* Sampler::Reset() no longer unloads instrument editor plugins, this is a
  workaround for the issue that instrument editor plugins were no longer
  available after sending a LSCP "RESET" command (probably due to a race).

* Bumped version (2.2.0.svn16).

1 Version SVN trunk (?)
2
3 * general changes:
4 - AbstractEngineChannel: fixed CCs not being forwarded to all
5 VirtualMIDIDevices.
6 - Fix compiler error with release tarball if no Bison installed
7 (SVN version still requires Flex and Bison being installed).
8 - Sampler::Reset() no longer unloads instrument editor plugins, this is a
9 workaround for the issue that instrument editor plugins were no longer
10 available after sending a LSCP "RESET" command (probably due to a race).
11
12 * Real-time instrument scripts:
13 - Fix: Do not share compiled instrument scripts among multiple engine
14 channels (sampler parts) as this can lead to crashes and would allow the
15 same global script variables to be accessible from multiple engine
16 channels which would not be the expected behaviour by instrument script
17 authors.
18
19 * GigaStudio/Gigasampler format engine:
20 - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
21 issues with .gig file.
22 - Use libgig's new method gig::File::GetSample() with method
23 gig::File::CountSamples() instead of now deprecated
24 gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
25 - Use libgig's new method gig::Instrument::GetRegionAt() with method
26 gig::Instrument:CountRegions() instead of now deprecated
27 gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
28 - Use libgig's gig::File::GetInstrument() method with method
29 gig::File::CountInstruments() instead of now deprecated
30 gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
31 - Show a more detailed error message on terminal if an appropriate editor
32 could not be found for a .gig instrument (if there is not any editor then
33 say so, if there is one but not capable to handle the instrument, then
34 make this case clear to the user; in both cases print the expected
35 location for instrument editor plugins).
36 - Fixed wrong velocity for release triggered samples: if and only if
37 note-off velocity is exactly zero (which means MIDI keyboard does not have
38 release velocity sensors) then use previous note-on velocity as note-off
39 velocity for release triggered samples instead.
40
41 * SFZ format engine:
42 - Fixed wrong velocity for release triggered samples: if and only if
43 note-off velocity is exactly zero (which means MIDI keyboard does not have
44 release velocity sensors) then use previous note-on velocity as note-off
45 velocity for release triggered samples instead.
46 - sfz.h: Added File::filename() method.
47 - sfz.h: Added File::checkFileModified() method allowing to detect file
48 changes (e.g. by other apps).
49 - sfz.h: Added Instrument::GetFile() method.
50 - Automatically reload .sfz files on file changes (e.g. by some external
51 text editor).
52
53 * MIDI driver:
54 - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
55 in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
56 - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
57
58 Version 2.2.0 (9 May 2021)
59
60 * general changes:
61 - Fixed compiler error in Pool.h.
62 - Require C++14 compiler support.
63 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
64 for checking in configure for C++14 support (as mandatory
65 requirement) and automatically adds compiler argument if required
66 (e.g. -std=C++14).
67 - RTMath: Implemented floating point comparison methods
68 fEqual32(float,float) and fEqual64(double,double) which take the
69 expected floating point tolerances into account.
70 - Added public API C++ class "LFO", which is a cluster class encapsulating
71 all the sampler's LFO implementations to be used by 3rd party applications
72 (e.g. by Gigedit).
73 - Added int math square LFO implementation.
74 - Added int math saw LFO implementation.
75 - Added numeric complex nr sine LFO implementation.
76 - Marked class LFOTriangleDiHarmonic as deprecated
77 (will be removed in future).
78 - Added LFOAll.h which includes all LFO implementation's header files.
79 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
80 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
81 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
82 SquareLFO -> LFOSquarePulse and separated the latter to its own header
83 file).
84 - Renamed type LFOSigned -> LFOTriangleSigned.
85 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
86 - Using now cubic interpolation as resampling algorithm by default; and
87 linear interpolation is deprecated now.
88 - Event:Init(): memset() entire Event::Param union to zero instead of trying
89 to do that for its individual members; the latter became error prone due
90 to the union's growing complexity meanwhile.
91 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
92 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
93 methods and marked the old ones as deprecated; and likewise added new
94 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
95 methods and marked those old ones deprecated as well.
96 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
97 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
98 - Implemented support for compressed RPN/NRPN message sequences (that is to
99 allow processing MIDI data entry messages without always having to be
100 preceded strictly by RPN/NRPN parameter selection messages on each value
101 change).
102 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
103 decrement).
104 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
105 MSB=127 and LSB=127) and which is disabling subsequent data
106 entry/increment/decrement CC messages.
107 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
108 instrument editor.
109 - Fixed playing noise at the end of a disk stream under certain conditions.
110 - Fixed potential crash with high pitch at end of RAM playback.
111 - Added configure checks whether C++ compiler supports so called
112 'designated initializers'.
113 - Added global backtraceAsString() function for debugging purposes
114 (POSIX systems only, no Windows implementation yet).
115 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
116 nameOfCaller() and setNameOfCaller().
117 - configure: Always check for availability of pthread_testcancel() and use
118 it if so (previously it was only used if explicitly enabled by configure
119 option).
120 - Thread class: raise compiler warning if pthread_testcancel() is not
121 available, because it can lead to deadlocks.
122 - Mutex class: Implemented optional bug detection and deadlock debugging
123 features.
124 - Ref<> class is now thread safe (as lock-free and wait-free
125 implementation).
126 - Fixed compilation error with Bison >= 3.6.0.
127 - Fixed rare crash when switching between instruments that had instrument
128 scripts loaded.
129 - Allow EffectChain::InsertEffect() as alternative to
130 EffectChain::AppendEffect() (i.e. with index equal to current chain size).
131 - ConstCapacityArray class: Fixed bug in remove() method.
132 - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
133 real-time instrument script was loaded.
134
135 * Real-time instrument scripts:
136 - Added method ScriptVM::setExitResultEnabled() which allows to
137 explicitly enable the built-in exit() function to optionally accept
138 one function argument; the value of the passed exit() function
139 argument will then become available by calling
140 VMExecContext::exitResult() after script execution.
141 - 64 bit support for NKSP integer scripts variables (declare $foo).
142 - Variable names, function names and preprocessor condition names must start
143 with a regular character (a-z or A-Z); starting them with a digit or
144 underscore is not allowed.
145 - NKSP parser fix: equal comparison operator "=" and not equal comparison
146 operator "#" must only accept integer operands.
147 - NKSP language: Implemented support for standard units like Hertz, seconds,
148 Bel including support for metric unit prefixes; so one can now e.g.
149 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
150 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
151 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
152 - NKSP language: Introduced "final" operator "!" which is specifically
153 intended for synthesis parameter values to denote that the synthesis
154 parameter value is intended to be the "final" value for that synthesis
155 parameter that should explicitly be used by the engine and thus causing
156 the sampler engine to ignore all other modulation sources for the same
157 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
158 variable or formula with this new "!" operator the expression is marked as
159 being "final".
160 - NKSP script editor API: Added support for detecting standard unit tokens
161 and their potential metric prefix token.
162 - NKSP language: Added support for NKSP real number literals and
163 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
164 - NKSP language: Added support for NKSP real number (floating point) script
165 variables (declare ~foo).
166 - NKSP language: Added support for NKSP real number (floating point) array
167 script variables (declare ?foo[]).
168 - Built-in script function "message()" accepts now real number argument as
169 well.
170 - Added built-in script function "real_to_int()" and its short hand form
171 "int()" for casting from real number to integer in NKSP scripts.
172 - Added built-in script function "int_to_real()" and its short hand form
173 "real()" for casting from integer to real number in NKSP scripts.
174 - Allow built-in exit() function to potentially accept real number type
175 argument as well.
176 - Built-in script functions may have a different return type depending on
177 the arguments passed to the function.
178 - Built-in script function "abs()" optionally accepts and returns real
179 number.
180 - Built-in script functions "min()" and "max()" optionally accept real
181 number arguments and return real number as result in that case.
182 - NKSP VM API: Allow units and 'final'ness to be returned as result from
183 built-in functions (added methods VMFunction::returnUnitType() and
184 VMFunction::returnsFinal() for that purpose which must be implemented by
185 built-in function implementations).
186 - NKSP language: Allow metric unit prefixes of numeric scalar and array
187 variables to be changed freely at runtime (unlike unit types like Hz etc.
188 which are still sticky, parse-time features of variables which cannot be
189 changed at runtime for the intentional sake of determinism).
190 - NKSP language: 'final' values are prohibited for array variables for now
191 (attempt causes a parsers error).
192 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
193 conditions of runtime control structures like if(), while(), select()
194 (attempt causes a parser error).
195 - NKSP VM API: Allow built-in functions to perform their own, individual
196 parse time checks of arguments going to be passed to the function at
197 runtime (added method VMFunction::checkArgs() for that purpose).
198 - NKSP language: raise parser warning if only one operand of binary
199 operators (like logical 'or' comparison) contain a 'final' value (because
200 it would always yield in a 'final' result in such cases).
201 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
202 different metric unit prefixes, which will behave as expected (e.g.
203 result of expression '1000us < 2ms' is true).
204 - NKSP language: Allow adding values with different metric unit prefixes
205 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
206 - NKSP language: Allow subtracting values with different metric unit
207 prefixes (e.g. result of expression '1ms - 20us' is '980us').
208 - NKSP language: Allow multiplying with any metric unit prefixes
209 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
210 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
211 we don't have any considerable practical use for a term like '4s^2'
212 (hence any attempt multiplying two unit types still causes parser error).
213 - NKSP language: Allow dividing by any metric unit prefixes and allow
214 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
215 yields in unit free result '8'). So this is now a way to cast units away
216 e.g. for passing the result to other expressions, certain function calls
217 or variables which are not accepting any units (or that specific unit).
218 - NKSP language: integer arrays and real number arrays can now be converted
219 to strings (e.g. for dumping their content with message() calls for
220 script debugging purposes).
221 - NKSP language: expressions and variables with units are now correctly
222 casted to strings (e.g. with message() calls).
223 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
224 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
225 floating point tolerances into account.
226 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
227 VMScalarNumberExpr::evalCastReal().
228 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
229 'VMIntArrayExpr' and 'VMRealArrayExpr'.
230 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
231 unitFactor() (runtime) methods.
232 - Built-in function "exit()" supports now returning units and 'final'ness
233 for test cases.
234 - The following built-in functions support now units as well: "abs()",
235 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
236 "real_to_int()", "int()", "int_to_real()" and "real()".
237 - Built-in functions "array_equal()", "search()" and "sort()" support now
238 real number arrays (correctly) as well.
239 - Added individual parse time checks of arguments to be passed to built-in
240 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
241 "array_equal()" and "search()" specific for their individual purposes.
242 - NKSP VM refactoring: Renamed all methods, functions and classes matching
243 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
244 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
245 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
246 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
247 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
248 isScalarNumber() -> isNumber()).
249 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
250 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
251 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
252 as convenient methods for automatically converting values to expected
253 metric value basis.
254 - Built-in function "wait()" accepts now both integers and real numbers as
255 argument.
256 - NKSP VM API cleanup: Get rid of legacy method
257 VMFunction::argType(vmint iArg) which was already superseded by its new
258 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
259 - NKSP parser: if wrong argument type was passed to a built-in function and
260 that built-in function accepts more than one data type for the argument,
261 then show all supported data types as parser error message.
262 - Built-in function "play_note()" accepts now real numbers and seconds as
263 unit type as well for its 3rd and 4th function arguments.
264 - The following built-in functions accept now real numbers as well for their
265 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
266 "change_attack()", "change_decay()", "change_release()",
267 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
268 "change_cutoff_sustain()", "change_cutoff_release()",
269 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
270 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
271 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
272 - Fixed built-in function "change_play_pos()" not having accepted metric
273 prefixes at all.
274 - Fixed the following built-in functions having misinterpreted values given
275 with unit type (for their 2nd argument) as if they were relative values
276 (that is as if they were passed without a unit type): "change_attack()",
277 "change_decay()", "change_release()", "change_cutoff_attack()",
278 "change_cutoff_decay()", "change_cutoff_release()".
279 - Fixed the following built-in functions having applied completely wrong
280 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
281 respective EGs being their modulation sink assume uint data type with
282 value range 0..1000 instead of 0.0..1.0.
283 - Added individual parse-time checks of function arguments for the following
284 built-in functions: "play_note()", "note_off()", "set_event_mark()",
285 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
286 "change_decay()", "change_release()", "change_cutoff_attack()",
287 "change_cutoff_decay()", "change_cutoff_release()",
288 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
289 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
290 "change_pan_time()".
291 - Don't abort function call if unit type was used and at the same time
292 'final' operator was omitted for the primary value argument of the
293 following built-in functions: "change_cutoff()", "change_attack()",
294 "change_decay()", "change_release()", "change_cutoff_attack()",
295 "change_cutoff_decay()", "change_cutoff_release()",
296 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
297 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
298 "change_pan_time()", instead imply 'final'ness at runtime and raise an
299 appropriate parser warning at parse time.
300 - Added built-in real number functions "round()", "ceil()", "floor()",
301 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
302 "cos()", "tan()", "asin()", "acos()", "atan()".
303 - Added built-in script real number constant "~NI_MATH_PI".
304 - Added built-in script real number constant "~NI_MATH_E".
305 - NKSP language: Allow unary '+' operator.
306 - Added built-in script functions "msb()" and "lsb()".
307 - NKSP language: Added support for RPN event handler
308 ("on rpn ... end on" in instrument scripts).
309 - NKSP language: Added support for NRPN event handler
310 ("on nrpn ... end on" in instrument scripts).
311 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
312 may be read from the new RPN/NRPN script handlers to get the (N)RPN
313 parameter that had been changed and its new value.
314 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
315 which are identifying the new (N)RPN handlers as such at script runtime.
316 - Implemented built-in script function "set_rpn()".
317 - Implemented built-in script function "set_nrpn()".
318 - Fix: built-in functions returning an array type were broken and caused a
319 crash when the built-in function's (supposed to be array) result value was
320 used by the script VM.
321 - Removed upper value constraint for 2nd argument of built-in functions
322 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
323 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
324 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
325 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
326 the LFO frequency / resonance / cutoff frequency.
327 - Reduced code involved for parsing NKSP variable declarations by using 2
328 generalized grammar rules with optional components (i.e. optional value
329 assignment and optional variable qualifiers) instead of previous linear
330 combinations of grammar rules, which also fixes some edge case.
331 - NKSP language parser: track code block locations also by a) raw byte
332 position in NKSP source code string and b) length of that code block in
333 bytes (along to the already existing code block tracking by line/column);
334 and added appropriate new members to public C++ API classes like
335 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
336 - NKSP language: Added support for 'patch' variable qualifier (capture their
337 locations and allow replacement of their assignment expression via VM C++
338 API).
339 - Fixed incorrect EG times if standard measuring unit was passed to built-in
340 functions "change_attack()", "change_decay()" or "change_release()".
341 - Fixed intermediate function result values never having reflected any
342 standard measuring unit type.
343 - Fixed re-entrant issue with function calls which caused wrong result
344 values if the same function was called multiple times in a term
345 (specifically if metric prefixes were used).
346 - NKSP language: Just throw a warning, not an error if an array variable of
347 size zero was declared.
348 - NKSP language: Allow omitting explicit array size on array variable
349 declaration if combined with immediate value assignment
350 (e.g. declare %foo[] := ( 1, 2, 3 ) ).
351 - NKSP language: emit warning if an array variable was declared with bigger
352 array size than amount of initial values been assigned, and initialize the
353 missing array elements with zero in this case.
354 - Fixed built-in NKSP exit() function to behave as return statement.
355 - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
356 data type.
357 - NKSP VM: Fixed the "release" handler being executed too often under
358 certain situations if polyphonic data was passed from "note" handler to
359 "release" handler.
360 - Fixed memory leak in NKSP parser: string tokens were allocated as C
361 strings and never freed.
362 - Fixed incorrect polyphonic data transfer from wrong note handler to
363 release handler; which also fixes no release handler being executed
364 sometimes, and due to the latter it also fixes potential crashes as some
365 polyphonic script events were never released and the engine hence was
366 running out of free script events.
367 - Fixed crash when handling array results of built-in functions
368 (e.g. "num_elements(by_marks($MARK_1)").
369 - NKSP VM: Fixed dead note events not been removed from user's event groups
370 (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
371 and set_event_mark() after max. size of event group list was exhausted).
372
373 * test cases:
374 - Fixed compiler errors in test cases.
375 - Updated README for how to compile & run test cases.
376 - Updated test case
377 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
378 expected behaviour of the Mutex class implementation (recursive
379 mutex type).
380 - Added test cases for NKSP core language aspects and core built-in
381 functions.
382 - Fixed thread tests segfaulting on Linux.
383 - NKSP: Added real number test cases for built-in functions exit(),
384 int_to_real(), real(), real_to_int() and int(), as well as for the
385 plus, minus and negate language operators.
386 - Added massive amount of NKSP test cases for standard measuring units and
387 'final' operator usage cases.
388 - Added NKSP test cases for (floating point tolerance aware) real number
389 equalness / unequalness comparison.
390 - Added NKSP int array and real array tests for value assignment and
391 initialization of arrays.
392 - Added NKSP test cases for built-in functions "round()", "ceil()",
393 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
394 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
395 - Added NKSP test cases for unary '+' operator.
396 - Added NKSP test cases for core built-in variables.
397 - Added thorough NKSP test cases for variable declarations.
398
399 * GigaStudio/Gigasampler format engine:
400 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
401 behaviour for start_level_mid.
402 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
403 level (see discussion "GigaStudio LFO compatibility" on mailing list
404 from 2019-09-26 for details).
405 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
406 see discussion "GigaStudio LFO compatibility" on mailing list from
407 2019-09-26 for details).
408 - Format extension: Added support for different LFO wave forms (currently
409 either sine [default], triangle, saw or square).
410 - Format extension: Added support for LFO phase displacement (0��..360��).
411 - Format extension: Added support for flipping LFO polarity on LFO 3
412 (in the original gig format this was only available for LFO 1 and LFO 2).
413 - Format extension: Support for additional filter types:
414 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
415 bandreject 2-pole.
416 - Fixd potential crash with polynomial interpolator and max. pitch.
417 - If minimum cutoff is defined, remap cutoff controller CC values to really
418 span the entire possible cutoff range (and avoiding a dead controller
419 zone).
420 - Implemented support for loading instrument scripts with 'patch' variables
421 (by patching these script variables with potentially overridden ones by
422 gig Instrument).
423
424 * SFZ format engine:
425 - Fixed support for regions with loccN/hiccN conditions on more than one
426 MIDI controller.
427 - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
428 'xfin_lovel' (patch by Christian Czezatke).
429
430 * Benchmarks:
431 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
432 algorithm (since result of 2nd run was not accumulated).
433 - Added benchmark for saw wave (benchmarks/saw.cpp).
434 - Added benchmark for sine wave (benchmarks/sine.cpp).
435 - Added benchmark for square wave (benchmarks/square.cpp).
436 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
437 which are large enough on modern systems.
438
439 Version 2.1.1 (27 Jul 2019)
440
441 * Real-time instrument scripts:
442 - Fixed behavior of built-in NKSP functions change_sustain(),
443 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
444 and change_cutoff_release().
445
446 * general changes:
447 - Only play release trigger samples on sustain pedal up if this behaviour
448 was explicitly requested by the instrument (otherwise only on note-off).
449 - Fixed compiler warnings.
450 - Fixed compilation error when cross-compiling to Mac.
451 - FX Sends: Provide more useful error messages on routing problems
452 (see bug #169).
453 - LSCP doc: Be more clear describing the two distinct approaches
454 of using external vs. internal effects (see bug #169).
455 - "optional" class: Fixed comparison operators.
456
457 * Gigasampler/GigaStudio format engine:
458 - Format extension: If requested by instrument then don't play release
459 trigger sample on note-off events.
460
461 * SFZ format engine:
462 - Fixed memory leak when releasing samples
463 (fixes bug #307, patch by Jacek Roszkowski)
464 - Fixed potential crash when a sample is shared by more than one region
465 (fixes bug #308, patch by Jacek Roszkowski).
466 - Opcode 'sample': Added support for built-in sample '*silence'
467 (fixes bug #310, patch by Jacek Roszkowski).
468
469 Version 2.1.0 (25 Nov 2017)
470
471 * SFZ format engine:
472 - added support for <global>, <master> and #define (patch by Alby M)
473 - Removed code duplication in SFZ file loading code.
474 - Added support for sfz extension opcode 'script' which may be used to
475 load real-time instrument script file (NKSP script language).
476 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
477 - Fixed unintended volume fade-in of voices under certain conditions.
478 - sfz parser: allow missing space between header and opcode
479
480 * Gigasampler/GigaStudio format engine:
481 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
482 cutoff settings.
483 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
484 all if an up-pitch of more than 40 semi tones was requested (I don't
485 think there is any stock gig sound that requires this behavior to
486 resemble its original sound).
487 - Added support for controlling whether the individual EGADSR stages may
488 be aborted (as LinuxSampler extension to the original GigaStudio 4
489 format).
490
491 * general changes:
492 - fixed printf type errors (mostly in debug messages)
493 - use unique_ptr instead of auto_ptr when building with C++11
494 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
495 allowing to sort data efficiently in real-time safe manner.
496 - RTList class: added methods for moving/inserting elements to arbitrary
497 position within a list.
498 - RTList class: added method fromPtr() for creating an Iterator object from
499 a raw element pointer.
500 - Attempt to partly fix resetting engine channels vs. resetting engine, an
501 overall cleanup of the Reset*(), ConnectAudioDevice(),
502 DisconnectAudioDevice() API methods would still be desirable though,
503 because the current situation is still inconsistent and error prone.
504 - Active voices are now internally grouped to "Note" objects, instead of
505 being directly assigned to a keyboard key. This allows more fine graded
506 processing of voices, which is i.e. required for certain instrument
507 script features.
508 - Fix: Release trigger voices were not spawned on sustain pedal up
509 (CC #64) events.
510 - Fix: Release trigger voices can now also distinguish correctly between
511 note-off and sustain pedal up events.
512 - All engines: Increased ramp speed of volume smoother and pan smoother
513 (while slow rate of crossfade smoother is preserved) to allow quick
514 volume and pan changes by instrument scripts for instance.
515 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
516 properly and thus were ignored for certain uses.
517 - Added new C++ API method
518 VirtualMidiDevice::SendChannelPressureToSampler().
519 - windows, 32-bit: fixed potential crashes by making sure the stack in
520 sub threads is 16-byte aligned
521 - fixed numerous compiler warnings
522 - Fixed invalid (note-on) event ID being assigned to new Note objects.
523 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
524 fixes potential undefined behavior.
525 - Fixed Note object leak when triggering notes on keys which did not
526 have a valid sample mapped (fixes bug #252).
527 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
528 - linuxsampler binary fix: option --create-instruments-db ignored
529 subsequent optional argument due to glibc's implementation oddity
530 which expects a "=" sign, but no space between them.
531
532 * packaging changes:
533 - removed unnecessary dependency to libuuid
534 (originated by libgig's usage of it)
535 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
536 auto detect whether it (sh/c)ould output its messages in color.
537 - Debian: Fixed packaging error about invalid "Source-Version"
538 substitution variable.
539 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
540 - Debian: Added build dependency to libsqlite3-dev for building
541 linuxsampler with instruments DB support.
542
543 * Real-time instrument scripts:
544 - Implemented scheduler for delayed MIDI events and for suspended scripts.
545 - Built-in script function "wait()": implemented support for function's
546 "duration-us" argument, thus scripts using this function are now
547 correctly resumed after the requested amount of microseconds.
548 - Built-in script function "play_note()": implemented support for
549 function's "duration-us" argument, thus notes triggered with this
550 argument are now correctly released after the requested amount of
551 microseconds.
552 - Fix: script events were not cleared when engine channel was reset,
553 potentially causing undefined behavior.
554 - Fixed crash which happened when trying to reference an undeclared
555 variable.
556 - Built-in script function "play_note()": Added support for passing
557 special value -1 for "duration-us" argument, which will cause the
558 triggered note to be released once the original note was released.
559 - Instrument script classes now exported with the liblinuxsampler C++ API.
560 - Added new API method ScriptVM::syntaxHighlighting() which provides
561 a convenient syntax highlighting backend for external instrument
562 script editor applications.
563 - Added new C++ API class "ScriptVMFactory".
564 - Extended parser issues to provide not only first line and first
565 column, but also last line and last column of issue (thus marking
566 the precise span of the issue within the source code).
567 - Reload script automatically after being modified by an instrument
568 editor.
569 - NKSP language grammar correction: allow empty event handler bodies
570 like "on note end on".
571 - Implemented built-in script function "change_vol()".
572 - Implemented built-in script function "change_tune()".
573 - Implemented built-in script function "change_pan()".
574 - Implemented built-in script function "change_cutoff()".
575 - Implemented built-in script function "change_reso()".
576 - Implemented built-in script function "event_status()".
577 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
578 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
579 "event_status()" function.
580 - NKSP language: Added support for bitwise operators ".or.", ".and."
581 and ".not.".
582 - NKSP language scanner: Fixed IDs matching to require at least one
583 character (i.e. when matching function names or variable names).
584 - NKSP language scanner: disabled unusued rules.
585 - Fixed behavior of play_note() and note_off() functions which must
586 be distinguished engine internally from "real" MIDI note on/off
587 events in order to avoid misbehaviors like hanging notes.
588 - Implemented built-in script variable "$KSP_TIMER".
589 - Implemented built-in script variable "$NKSP_REAL_TIMER".
590 - Implemented built-in script variable "$NKSP_PERF_TIMER".
591 - Implemented built-in script variable "$ENGINE_UPTIME".
592 - Implemented built-in script function "inc()".
593 - Implemented built-in script function "dec()".
594 - NKSP language fix: division expressions were evaluated too often.
595 - NKSP language fix: string concatenation operator was right
596 associative instead of left (to right).
597 - NKSP language correction: allow empty statements in entire language
598 (i.e. "if end if").
599 - Implemented built-in script function "stop_wait()".
600 - Implemented built-in script variable "$NI_CALLBACK_ID".
601 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
602 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

605 - Added built-in script constant "$NI_CB_TYPE_INIT".
606 - Added built-in script constant "$NI_CB_TYPE_NOTE".
607 - Added built-in script constant "$NI_CB_TYPE_RELEASE".

610 - Implemented built-in script function "change_attack()".
611 - Implemented built-in script function "change_decay()".
612 - Implemented built-in script function "change_release()".
613 - Fixed all change_*() built-in script functions to apply their
614 synthesis parameter changes immediately in case the respective note
615 was triggered at the same time, instead of scheduling the parameter
616 change, especially because it would cause some parameter types's
617 changes either to be ramped (i.e. change_vol()) or other types even
618 to have not effect at all (i.e. change_attack()).
619 - Implemented built-in script function "sh_left()".
620 - Implemented built-in script function "sh_right()".
621 - Implemented built-in script function "min()".
622 - Implemented built-in script function "max()".
623 - NKSP Fix: "init" event handler was not always executed when a script
624 was loaded.
625 - NKSP built-in wait() script function: abort script execution if
626 a negative or zero wait time was passed as argument (since this is
627 a common indication of a bug either of the script or even of the
628 engine, which could lead to RT instability or even worse).
629 - ScriptVM: Implemented automatic suspension of RT safety
630 threatening scripts.
631 - Provide more user friendly error messages on syntax errors.
632 - Fixed NKSP parser warning "Not a statement" when assigning an
633 initializer list to an array variable.

635 - Implemented built-in script function "in_range()".
636 - Implemented built-in script function "change_amp_lfo_depth()".
637 - Implemented built-in script function "change_amp_lfo_freq()".
638 - Implemented built-in script function "change_pitch_lfo_depth()".
639 - Implemented built-in script function "change_pitch_lfo_freq()".
640 - Implemented built-in script function "change_vol_time()".
641 - Implemented built-in script function "change_tune_time()".
642 - Implemented built-in script function "fade_in()".
643 - Implemented built-in script function "fade_out()".
644 - Fixed acceptance of wrong data type of parameters passed to built-in
645 script functions "change_vol()", "change_tune()", "change_pan()",
646 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
647 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
648 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
649 - Added built-in script function "get_event_par()" and implemented some
650 of its possible parameter selections.
651 - Added built-in script function "set_event_par()" and implemented some
652 of its possible parameter selections.
653 - Fixed a bunch of scheduler time related bugs.
654 - Fixed polyphonic variables not being reset to zero after usage.
655 - Built-in "ignore_event()" function: argument is now optional, like with
656 built-in function "ignore_controller()".
657 - Implemented built-in script function "change_velo()".
658 - Implemented built-in script function "change_note()".
659 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
660 intuitive behavior if used in combination with "change_vol_time()" or
661 "change_tune_time()" respectively: now tuning/volume changes are only
662 assigned (without delay) immediately to a new note if the respective
663 timing function has not been called before, otherwise the volume/tuning
664 changes are automatically faded (before, only the event's time stamp was
665 relevant).
666 - Implemented built-in script function "array_equal()".
667 - Implemented built-in script function "search()".
668 - Implemented built-in script function "sort()".
669 - NKSP Fix: Never suspend "init" event handlers.
670 - Implemented built-in script function "same_region()" (currently only
671 available for gig format engine).
672 - Added built-in script constant "$NKSP_LINEAR".
673 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
674 - Implemented built-in script function "change_vol_curve()".
675 - Implemented built-in script function "change_tune_curve()".
676 - built-in "play_note()" function now supports a sample playback start
677 offset with argument 3, where special value -1 means to use the regular
678 sample offset as defined by the instrument file.
679 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
680 - Built-in variable $EVENT_NOTE is now a read-only variable.
681 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
682 - built-in "play_note()" function now accepts -2 for its fourth argument
683 (note duration) which means the life time of the note shall be sticked
684 to the requested note number of argument 1.
685 - Fix: built-in "play_note()" function now returns 0 as result value if
686 -1 was passed for its fourth argument (note duration) and the respective
687 parent note is already gone.
688 - Implemented built-in script function "change_play_pos()".
689 - NKSP language: Added support for user declared const array variables.
690 - NKSP language: Raise parser warning if array variable is accessed with
691 an index that exceeds the array's size.
692 - NKSP language fix: Unknown characters were not handled correctly.
693 - NKSP language: Added support for "synchronized .. end synchronized"
694 code blocks.
695 - Implemented built-in script function "abort()" which allows to abort
696 another script handler by passing its callback ID.
697 - Fixed potential memory access bug and potential undefined behavior of
698 "init" event handlers.
699 - Print a time stamp along to each call of built-in function "message()".
700 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
701 to retrieve all code blocks filtered out by the preprocessor.
702 - Added built-in script function "fork()".
703 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
704 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
705 - Fixed potential crash when accessing dynamic built-in array variables.
706 - Added built-in script function "callback_status()".
707 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
708 - Added built-in constant $CALLBACK_STATUS_QUEUE.
709 - Added built-in constant $CALLBACK_STATUS_RUNNING.
710 - Removed max. value limitation of built-in functions "change_attack()",
711 "change_decay()" and "change_release()" to i.e. allow passing 2000000
712 for doubling the respective time.
713 - NKSP script editor syntax highlighting API: Fixed app termination due
714 to a lexer start condition stack underrun.
715 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
716 USE_CODE_IF_NOT() preprocessor statements.
717 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
718 can be set to disable all subsequent built-in "message()" function calls
719 on preprocessor level.
720 - Implemented built-in script function "change_sustain()".
721 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
722 to avoid the editor app to crash on ill-formed text input.
723 - Added built-in script function "change_pan_time()".
724 - Added built-in script function "change_pan_curve()".
725 - Added built-in script function "change_cutoff_attack()".
726 - Added built-in script function "change_cutoff_decay()".
727 - Added built-in script function "change_cutoff_sustain()".
728 - Added built-in script function "change_cutoff_release()".
729 - Added built-in script function "change_cutoff_lfo_depth()".
730 - Added built-in script function "change_cutoff_lfo_freq()".
731
732 * Instruments DB:
733 - Fixed memory access bug of general DB access code which lead to
734 undefined behavior.
735 - Cleanup of instruments DB file creation and opening code.
736 - The instrument DB path of linuxsampler's --create-instruments-db argument
737 is now optional, if it is missing, then a default location is used.
738 - Added support for scanning SFZ (.sfz) files.
739 - Added support for scanning Sound Font (.sf2) files.
740 - Fixed undefined DB transaction behavior.
741
742 Version 2.0.0 (15 July 2015)
743
744 * packaging changes:
745 - fixed building with newer MinGW-w64
746 - Mac OS X: support the new dir for Core Audio SDK
747 - Mac OS X: fixed building outside source directory
748 - made sure all source files for hostplugins are included when
749 doing "make dist"
750 - removed empty directories left from the cvs to svn migration
751 - fixed compilation with gcc 4.6.1
752 - another "make dist" fix, for the LV2 plugin
753 - made --enable-pthread-testcancel default on Mac OS X
754 - minor Makefile fix for building lscpparser when build and source
755 directories are separate
756 - Mac OS X: made it possible to specify plugin installation dir to
757 configure
758 - Mac OS X: Makefile fix for the install-strip target
759 - fixed compilation with gcc 4.7
760 - fixed configure script error with old autoconf versions
761 - lsatomic.h: use gcc provided atomic functions if building with
762 gcc 4.7 and C++11
763 - modernized configure script
764 - fixed linkage error when building with
765 LDFLAGS="-Wl,--no-undefined" (#190)
766 - fixed compilation with Clang 3.2
767 - removed usage of deprecated Automake variable INCLUDES
768 - fixed building with C++11
769 - build fix: ChangeFlagRelaxed.h was missing in makefile
770 - build fix: libsndfile compiler flags were missing in some
771 makefiles
772 - fix for building with bison 3.0 (#202)
773 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
774 on the process's main thread
775 - fixed build error on newer MinGW
776 - support building with older jack versions
777 - support building with spaces in vst sdk path
778 - enabled automake 'subdir-objects' option and moved external
779 source references (vst, au, asio) from makefiles to cpp files,
780 in order to get rid of warnings from automake 1.14
781
782 * general changes:
783 - Refactoring: moved the independent code from
784 the Gigasampler format engine to base classes
785 - command line option '--profile' is currently disabled, since the
786 respective profiling code is currently broken
787 - Introduced support for optional environment variable
788 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
789 where the sampler shall look for instrument editor plugins
790 (patch by Luis Garrido, slightly modified).
791 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
792 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
793 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
794 note (in this implementation of the sampler its simply hard routed to
795 the 1st effect send of the sampler channel, no matter what the actual
796 effect type is)
797 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
798 note (in this implementation of the sampler its simply hard routed to
799 the 2nd effect send of the sampler channel, no matter what the actual
800 effect type is)
801 - implemented support for internal LADSPA effects
802 - raised limit of program change queue from 100 to 512
803 (as suggested by Alex Stone)
804 - implemented sine LFO, pulse LFO and saw LFO
805 - experimental support for per voice equalization
806 - added command line option --exec-after-init
807 - Introduced new C++ API method:
808 EngineChannel::InstrumentFileName(int index)
809 allowing to retrieve the whole list of files used for the loaded
810 instrument on an engine channel (a.k.a. part). Some GigaStudio
811 instruments for example are splitted over several files like
812 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
813 - Added new C++ API method Sampler::GetGlobalMaxVoices().
814 - Added new C++ API method Sampler::GetGlobalMaxStreams().
815 - Added new C++ API method Sampler::SetGlobalMaxVoices().
816 - Added new C++ API method Sampler::SetGlobalMaxStreams().
817 - Various "const" and "restrict" optimizations.
818 - all engines: add pan CC value to instrument pan parameter before
819 applying panning, instead of using two separate pan functions in
820 series (#182)
821 - added a lock guard class for exception safe mutex handling and
822 used it everywhere appropriate
823 - Immediately apply scale tuning changes to active voices.
824 - Exposed scale tuning to C++ API (along to the already existing standard
825 SysEx way).
826 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
827 and broken for ppc64. (Seq_cst loads and stores are actually not
828 used in LS, so the bug wasn't noticable.)
829 - lsatomic.h: added ARMv7 support
830 - Added support for multiple MIDI input ports per sampler channel (and
831 added various new C++ methods for this new feature / design change, old
832 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
833 as deprecated but are still there and should provide full behavior
834 backward compatibility).
835 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
836 unsafe and caused compilation error with clang 2.x).
837 - Bugfix: only process the latest MIDI program change event.
838 - Introducing the LSCP shell, which provides convenient control of the
839 sampler from the command line by providing LSCP aware features.
840 - VirtualMidiDevice: Added support for program change.
841 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
842 - VirtualMidiDevice: Added support for pitch bend.
843 - Aftertouch: extended API to explicitly handle channel pressure and
844 polyphonic key pressure events (so far polyphonic pressure was not
845 supported at all, and channel pressure was rerouted as CC128 but not
846 used so far).
847 - Added initial support for real-time instrument scripts. The script VM
848 code is shared by all sampler engine implemementations, however only the
849 gig file format currently provides support for storing instrument scripts
850 (as LinuxSampler extension to the original GigaStudio 4 format).
851
852 * Gigasampler format engine:
853 - implemented the "round robin keyboard" dimension
854 - fixed round robin and random dimensions for cases when number of
855 dimension zones is not a power of two
856 - made round robin use a counter for each region instead of each
857 key
858 - bugfix: pitch LFO controller "internal+aftertouch" was broken
859 - bugfix: filter keyboard tracking was broken
860 - filter performance fix (an unnecessary copy was made of the
861 filter parameters in each sub fragment)
862 - handle special case when pan parameter in gig file has max or
863 min value
864 - Exclusive Groups: don't ever stop voices of the same note,
865 doesn't sound naturally with a drumkit
866 - fixed EG1 modulation when attack or release is zero
867 - Fixed support for 'aftertouch' attenuation controller.
868 - Fixed crash that happened with velocity split sounds under certain
869 conditions (see also previous commit on libgig).
870 - fixed behaviour of filter LFO
871
872 * SFZ format engine:
873 - Initial implementation (not usable yet)
874 - added support for v2 multiple stage envelope generators
875 - added a fine-tuned v1 envelope generator instead of using the
876 one from the gig engine

1100 the driver will automatically connect to other CoreMIDI clients' ports
1101 (e.g. external MIDI devices being attached to the Mac)
1102 - added support for MIDI note on velocity filter
1103 - CoreMIDI: fixed memory deallocation error

1257 which min and/or max values depend on the sample rate
1258 - fixed bug #162
1259 - bugfix: LADSPA_PATH was not evaluated correctly when containing
1260 multiple paths (#165)
1261 - thread safety fixes for the instrument loading thread
1262 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1263 (#176)
1264 - more thread safety fixes for the instrument loading thread
1265 - sfz/sf2 engine: fixed crash when using small audio fragment size
1266 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1267 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1268 introduced in previous fix)

1273 - Update effects on sample rate & period size changes (to avoid
1274 crashes and noise on such transitions).
1275 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1276 (fixes #208)
1277 - Fixed bug in LSCP grammar definition which caused a statement like
1278 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1279 practically irrelevant, however it caused problems with the new LSCP
1280 shell's auto completion feature).
1281 - Fixed MIDI program change messages being ignored if quickly executed
1282 after each other (fixes #231).
1283
1284 Version 1.0.0 (31 July 2009)
1285
1286 * packaging changes:
1287 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1288 causing e.g. the libgig test to fail when
1289 "./configure --disable-jack-driver" was used
1290 (patch by Alexis Ballier)
1291 - fixed compilation with gcc 4.3
1292 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1293 - fixed configure so it detects x86_64 (#107)
1294 - fixes for building with newer MinGW versions
1295 - fix for building with bison 2.4 (#111)
1296 - fixed building with libgig installed in a non-standard directory
1297 - minor fix in configure for mmsystem.h detection on MinGW
1298 - Windows: look for editor plugins and Fantasia using base
1299 directory of liblinuxsampler dll (look in the same directory and one
1300 directory above)
1301 - configure script fix: removed unconditional use of SSE
1302 - fixed building with sqlite installed in a non-standard directory
1303 - when cross-compiling, don't try to create instruments.db
1304 - fix for new mingw-w64 version, which has usleep
1305
1306 * general changes:
1307 - bugfix: on some POSIX systems instrument editor plugins refused to
1308 load as we used a non-portable Linux specific struct field
1309 (fixes bug #70, patch by Ronald Baljeu)
1310 - fixed endless loop which occured when loading an instrument editor
1311 plugin DLL on Windows systems failed
1312 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1313 - optimized the SynchronizedConfig class so it doesn't wait
1314 unnecessarily long after an update
1315 - added support for notifying instrument editors on note-on / note-off
1316 events (e.g. to highlight the pressed keys on the virtual keyboard
1317 of gigedit)
1318 - added support for triggering notes by instrument editors (see above)
1319 - be verbose on DLL load errors (on Linux)
1320 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1321 is only used by very few systems, most pick the int math
1322 implementation, which is usually faster)
1323 - fixes for audio drivers with varying buffer sizes
1324 - experimental support for running LinuxSampler as a DSSI, LV2 and
1325 VST plugin
1326 - notification events for stream/voice count statistics are now sent
1327 only when there are actual changes
1328 - added memory ordering constraints to improve stability on
1329 multi-core and multi-cpu systems
1330 - maximum voices and disk streams can now be altered at runtime
1331 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1332 - automatic stacktrace mechanism is now turned off by default and can
1333 be switched on by command line option "--stacktrace" (the automatic
1334 stacktrace mechanism seems to be broken on most systems at the moment)
1335 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1336 a pointer to the launched InstrumentEditor object
1337 - added optional 3rd party user data parameter for following
1338 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1339 InstrumentEditor::Launch(),
1340 InstrumentManager::LaunchInstrumentEditor()
1341 - theoretical fix: made SynchronizedConfig follow C++0x memory
1342 model more strictly
1343 - fixes for using large audio device buffers
1344 - Windows: add the installation directory to the DLL search path
1345 when loading an editor plugin (solves problems with VST and
1346 gigedit on systems with other GTK versions installed)
1347 - updated linuxsampler man page
1348
1349 * audio driver:
1350 - removed the nonsense audio channel constraint (which was hard coded to
1351 max. 100 audio channels) for most audio drivers
1352 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1353 opposed to the LSCP specs
1354 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1355 reflected the wrong value
1356 - fixed a memory management bug in ASIO driver
1357 - Makefile fix: JACK_CFLAGS wasn't used
1358 - JACK: use jack_client_open instead of the deprecated
1359 jack_client_new
1360 - added (experimental) CoreAudio driver
1361 - applied old fixes to the ASIO driver that were included in the
1362 previous binary release but accidentally never committed to CVS
1363 (fixes #117)
1364 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1365 win64)
1366 - VST: added support for sample rate and buffer size changes
1367 - VST: close editor (Fantasia) when the VST is removed
1368 - VST: avoid opening Fantasia more than once for each VST instance
1369 - VST: export main function as "main" on Linux too (fix for
1370 energyXT)
1371 - VST: changed number of output channels from one stereo to 16
1372 stereo
1373 - added channel routing, fxsends and midi maps to the settings
1374 stored in the plugin state
1375 - performance optimization of AudioChannel::MixTo() and
1376 AudioChannel::CopyTo() methods using GCC vector exensions
1377 (if available)
1378 - ASIO fixes: avoid initializing the device twice, avoid throwing
1379 exception when getting parameters from a disconnected device
1380
1381 * MIDI driver:
1382 - added JACK MIDI driver
1383 - dispatch bank select as ordinary CC as well, the user might seriously
1384 want to (mis)use it for some purpose ("fixed" in all current MIDI
1385 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1386 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1387 CoreMidi or AU
1388 - fixed mingw-w64 compilation error in MME driver
1389 - made program change handling in MIDI thread real-time safe by
1390 moving the logic to a non-RT thread
1391 - fixed minor memory leak in ALSA driver
1392
1393 * instruments database:
1394 - avoid time consuming samples scanning when adding instruments
1395 to the instruments database
1396 - added support for handling lost files in the instruments database
1397 - Implemented option for adding instruments in separate directories
1398 in the instruments database
1399 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1400 - work-around for missing fnmatch function on Windows to make
1401 instrument database compilable
1402 - added instrument database support on Windows
1403 works with both standalone mode and VST plugin.
1404 the instruments DB file is located in
1405 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1406 databases for each windows user
1407 if no DB is present it automatically creates the .linuxsampler subdir
1408 and then creates an empty DB
1409 - fixed recursive import, which was broken on Windows
1410
1411 * Gigasampler format engine:
1412 - fixed a memory leak that could happen when a channel was deleted
1413 while notes were playing
1414 - made it possible to load an instrument even if the audio thread
1415 isn't running
1416 - added partial support for the "Controller Triggered" MIDI rule,
1417 enough for piano gigs with pedal noise samples
1418 - minor fix: only mark FX sends as being modified if really the
1419 respective FX send MIDI controller was used
1420 - added support for GM global device volume SysEx message
1421 (can be selected at compile time to either apply globally to the
1422 whole sampler [default] or only to the sampler channels that are
1423 connected to the respective MIDI input port the SysEx message arrived
1424 on)
1425 - bugfix: notes triggered at position 0 in the audio buffer were
1426 sometimes wrongly killed in the same buffer, causing no sound to
1427 be played
1428 - added support for chromatic / drumkit mode Roland GS Sysex message
1429 which is usally used to switch a part between chromatic sounds and
1430 drumkit sounds (as opposed to their common default setting of MIDI
1431 part 10 being a drumkit part and all other ones chromatic parts), in
1432 LS however one can switch between the first 16 MIDI instrument maps
1433 defined for the sampler
1434 - made it possible to create multiple sample channels even if the
1435 audio thread isn't running
1436 - fixed crash when removing channel with active voices (#116)
1437 - bugfix: on sample reference changes (instrument editor), only
1438 un-cache the respective sample if it's really not used by any
1439 sampler engine anymore
1440 - re-cache samples in case they were changed by an instrument editor,
1441 e.g. when a sample was added while playing (#82)
1442 - fixed hanging notes which occured when note-off event had the exact
1443 same time stamp as the voice's note-on event and occured both in the
1444 same audio fragment cycle (fixes bug #112)
1445 - added support for the "fine tune" and "pitch bend range"
1446 instrument-level gig parameters
1447 - fixed minor artifacts in pitch bend handling
1448 - added support for GS Reset SysEx message
1449 - allow gig files to use unlimited downward pitch shifting
1450 - added a limit check for upward pitch shifting
1451 - bugfix: sometimes, when playing a note twice fast, the second
1452 note was silent
1453 - fixed crash happening when a pitch bend event arrived at the
1454 same time a new instrument was loading
1455
1456 * LSCP server:
1457 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1458 react on MIDI data arriving on certain sampler channels (so far only
1459 Note-On and Note-Off events are sent via this LSCP event)
1460 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1461 react on MIDI data arriving on certain MIDI input devices (so far only
1462 Note-On and Note-Off events are sent via this LSCP event)
1463 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1464 SET DB_INSTRUMENT FILE_PATH
1465 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1466 frontends to send MIDI messages to specific sampler channel
1467 - added two additional fields to GET FILE INSTRUMENT INFO command -
1468 KEY_BINDINGS and KEYSWITCH_BINDINGS
1469 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1470 was incorrect
1471 - Optimized the retrieval of the MIDI instrument mappings
1472 - added new LSCP command "SET VOICES" to globally alter the maximum
1473 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1474 be triggered respectively
1475 - added new LSCP command "SET STREAMS" to globally alter the maximum
1476 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1477 which will be triggered respectively
1478 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1479 a gigedit file dialog is opened)
1480 - close all connections when LSCPServer is deleted
1481 - hard close of all sockets on exit
1482 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1483 driver
1484
1485 * Bug fixes:
1486 - fixed a crash which occurs when removing a sampler channel waiting
1487 to start instrument loading after another channel
1488 - fixed a crash which occurs when removing a sampler channel with
1489 instrument loading in progress (bug #113)
1490 - fixed termination caused by uncaught exception when adding MIDI
1491 instrument with PERSISTENT load mode
1492 - fixed possible iterator invalidations when resetting the sampler
1493 - fixed memory leaks when issuing the following LSCP commands:
1494 GET AUDIO_OUTPUT_DRIVER INFO
1495 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1496 GET MIDI_INPUT_DRIVER INFO
1497 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1498 - fixed possible compilation error when sqlite is not present
1499 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1500 - fixed crash when changing the audio output device of a sampler
1501 channel with loaded instrument and start playing notes
1502 - fixed endless loop in Engine::SuspendAll() (bug #120)
1503 - fixed a low-level atomic load function that was broken on 64-bit
1504 PowerPC, which probably could cause crashes on that platform
1505 - fixed a memory management error which could cause a crash when a
1506 plugin was unloaded
1507 - bugfix: two private structs had the same name, which could cause
1508 problems if the linker chose the wrong constructor
1509 - fixed low-level ConditionServer usage bug that caused lockups on
1510 Windows
1511
1512
1513 Version 0.5.1 (6 December 2007)
1514
1515 * packaging changes:
1516 - added autoconf checks for pthread library
1517 - added autoconf check for pthread bug found on certain NPTL-enabled
1518 glibc versions (see Gentoo bug report #194076)
1519 - added autoconf checks for MS Windows
1520
1521 * general changes:
1522 - bugfix: the thread used by an editor plugin didn't die when the
1523 editor closed
1524 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1525 out all the space. operator--() did not apply size_mask after
1526 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1527 order to avoid problems with the _NonVolatileReader functions.
1528 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1529 GetWriteSpace(). Since this function is currently only used in
1530 the stream's qsort() compare function, it didn't trigger any
1531 bugs.
1532 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1533 24bit mode too. Faster method to read 24bit words on little
1534 endian machines (x86): replaced 3 byte reads + shifts with a 1
1535 unaligned 32bit read and shift
1536 - experimental support for MS Windows (MIDI input via MME, AUDIO
1537 output via ASIO)
1538 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1539 - support for monitoring the total number of active disk streams
1540 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1541 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1542
1543 * AUDIO driver:
1544 - added Windows ASIO low latency audio driver
1545
1546 * MIDI driver:
1547 - added MME Windows MIDI driver
1548
1549 * LSCP server:
1550 - added support for Windows style path / filenames, however with
1551 forward slash path separators instead of backslash
1552 (i.e. "C:/foo/bar.gig")
1553 - allow naughty liblscp to send non-string device parameters within
1554 apostrophes as well
1555 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1556 "LIST FILE INSTRUMENTS <file>" and
1557 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1558 about an arbitrary instrument file on the system where the sampler is
1559 running on
1560
1561 Version 0.5.0 (15 October 2007)
1562
1563 * packaging changes:
1564 - config.h is not going to be installed along with liblinuxsampler's
1565 API header files anymore
1566 - only the API relevant header (and source) files will be exported to
1567 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1568 - added completely new XCode project files for Mac OSX which is now
1569 capable to execute our autoconf environment, thus no need anymore
1570 to maintain the compile time configuration file (osx/version.h) for
1571 OSX manually (patch by Toshi Nagata)
1572 - fixed buggy boolean --enable-foo / --disable-foo configure script
1573 parameters
1574 - global.h now only covers global definitions that are needed for the
1575 C++ API header files, all implementation internal global definitions
1576 are now in global_private.h
1577 - atomic.h is not exposed to the C++ API anymore
1578 - no need to include config.h anymore for using LS's API header files
1579 - fixed warnings in API doc generation
1580
1581 * general changes:
1582 - replaced the old, confusing MIDI program change mechanism by a
1583 flexible MIDI instrument mapper which allows to map arbitrary
1584 (MIDI bank, MIDI program) pairs with arbitrary
1585 (engine type, instrument file, file index) triplets which will be
1586 loaded on the respective channel when such MIDI program change
1587 messages arrive, beside that, each entry allows to define a life-time
1588 strategy for the instrument, so the user can define whether the
1589 instrument should i.e. be permanently loaded (to be able to switch
1590 quickly among sounds) or i.e. loaded just on demand when the
1591 respective program change arrives (to safe RAM space), as well as a
1592 global volume factor for each entry, so the user can adjust the volume
1593 dynamic of his mapped instrument collection without having to modify
1594 the instrument files, also one can manage arbitrary amount of such
1595 MIDI instrument maps and assign each sampler channel individually
1596 a certain map, so that i.e. separation of normal instruments and
1597 drumkits is possible
1598 - new notification events for tracking changes to audio/MIDI devices,
1599 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1600 - sampler was limited to load max. 200 instruments in the background
1601 due to a constant size RingBuffer FIFO which is now replaced by a
1602 dynamic (unlimited) size std::list FIFO
1603 - added FX sends, these allow to route audio signals to arbitrary audio
1604 output channels for being processed by external effect processors
1605 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1606 controllers
1607 - global (sampler wide) volume can now be controlled at runtime
1608 - Implemented new, improved notification system
1609 - fixed compilation errors regarding OSX
1610 (patch by Toshi Nagata)
1611 - implemented instruments database
1612 - added support for escape sequences to the instruments database
1613 - added highly experimental support for on-the-fly instrument editing
1614 within the sampler's process (by using instrument editor plugins),
1615 you'll notice the new "Registered instrument editors:" message on
1616 startup, added a new LSCP command:
1617 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1618 to spawn a matching instrument editor for the instrument on the
1619 given sampler channel, the plugin path can be overridden at compile
1620 time with ./configure --enable-plugin-dir=/some/dir
1621 - added experimental code for synchronizing instrument editors hosted
1622 in the sampler's process to safely edit instruments while playing
1623 without a crash (hopefully) by either suspending single regions
1624 wherever possible or if unavoidable whole engine(s)
1625 - fixed several issues in fundamental "Thread" class: set scheduling
1626 policy and priority on thread level, set a minimum stack size for
1627 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1628 threads simply inherited properties of starting thread instead of
1629 setting their own policy and priority
1630 - minor fix in our automatic stack trace mechanism on crashes, the
1631 main process did not wait for the stack trace process to finish
1632 its output
1633 - fixed some minor memory leaks
1634 - reenabled assembly features support, at the moment only for
1635 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1636 - minor assembly fix in x86 features detection (don't use the PIC
1637 register, to avoid relocations in the text segment at runtime)
1638 - POSIX callback functions of Thread.h are hidden
1639
1640 * MIDI driver:
1641 - dispatch bank select (MSB and LSB) messages
1642
1643 * audio driver:
1644 - the ALSA audio output driver parameters now reflect the correct
1645 parameter value ranges for the respective selected sound card
1646 (patch by Till Wimmer, a bit fixed and extended)
1647
1648 * Gigasampler format engine:
1649 - if a filter is used and EG2 finishes before EG1, let the voice
1650 die when EG2 has finished (this fixes a problem with clicks and
1651 voice starvation for some gigs)
1652 - playback is no longer disabled during instrument loading
1653 - all notes playing on a channel that changes its instrument keep
1654 playing with the old instrument until they get a note off
1655 command
1656 - EG fix: a release value of zero could cause noises or crash
1657 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1658 - EG fine tuning: when attack is zero the EG starts at a level
1659 above max sustain level, which means that there is a decay phase
1660 even if sustain is 100%
1661 - more EG fixes: the level could sometimes go below zero and cause
1662 noises or crashes
1663 - minor fix of EGDecay (patch by Toshi Nagata)
1664 - fixed compiler error when --enable-override-filter-type was
1665 supplied to the configure script (fixes #46)
1666 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1667 instead of a fix value
1668 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1669 127 (solo mode) only kill voices if the respective mode really
1670 changed
1671
1672 * LSCP server:
1673 - fixed compile time error for old Bison versions
1674 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1675 - parser now supports extended ASCII character set
1676 (up to ASCII code 255, i.e. includes now umlauts and accents)
1677 - filename arguments in LSCP commands now allow to use escape
1678 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1679 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1680 code value like \xf2) (fixes bug #24)
1681 - the following LSCP commands now also support escape sequences for at
1682 least one of their text-based parameters (i.e. name, description):
1683 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1684 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1685 "SET DB_INSTRUMENT_DIRECTORY NAME",
1686 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1687 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1688 "FIND DB_INSTRUMENT_DIRECTORIES"
1689 - returns verbose syntax errors (line and column where syntax error
1690 occured, the unexpected character and the actually expected, possible
1691 character(s), the latter only if less than 5 possibilities)
1692 - made sure that LSCP syntax is not affected by gigedit locale
1693 settings
1694 - bugfix regarding strings parameter lists: all comma separated lists
1695 of strings were treated as being one string containing commas
1696 (fixes #57)
1697
1698 * Bug fixes:
1699 - fixed crash occurring on certain LSCP scripts (Bug 39)
1700 - another thread safety fix for lscp "load engine" and "set
1701 channel audio output device"
1702 - fixed a crash which occurs when reassigning the same engine
1703 on a sampler channel with connected MIDI device
1704 - fixed a crash which occurs when changing the number of ports of a MIDI
1705 device connected to a sampler channel to number less then or equal
1706 to the index of the port to which the sampler channel is connected.
1707 - The previous bindings were not been disconnected when altering
1708 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1709 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1710 - The active stream/voice count statistic was incorrect.
1711 - notification events were not been sent for some sampler
1712 channel changes
1713 - added default min and max values to restrict the number of allowed
1714 audio output channels and MIDI input ports
1715 - the connection to the PCM interface is now closed when destroying
1716 an audio output device
1717 - files with slash in their path or filename could not be loaded
1718
1719 * test cases:
1720 - updated and fixed (haven't been touched in a while)
1721
1722 Version 0.4.0 (24 November 2006)
1723
1724 * packaging changes:
1725 - changed deprecated copyright attribute to license; added ldconfig
1726 to post-(un)install steps; added devel package for liblinuxsampler;
1727 to linuxsampler.spec (RPM)
1728 - install necessary development header files for allowing 3rd party
1729 applications to link against liblinuxsampler
1730 - liblinuxsampler's API documentation can be generated with 'make docs'
1731 (Doxygen required)
1732 - added benchmark to automatically detect the best triangle LFO
1733 implementation (currently either an integer math solution or a
1734 di-harmonic approximation), automatic detection can be overriden
1735 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1736 configure script argument though (mandatory for cross-compilation)
1737 - do not automatically pick optimized gcc flags if the user already
1738 provided some on his own (as CXXFLAGS)
1739 - added compile time option to disable processing of All-Notes-Off MIDI
1740 messages
1741 - added compile time options to allow disabling the various audio and
1742 MIDI drivers
1743 - fixed automatic GCC CPU switch detection on PPC
1744 (patch by Ebrahim Mayat)
1745
1746 * Gigasampler format engine:
1747 - extensive synthesis optimization
1748 (reimplementation of EGs and LFO(s), removed synthesis parameter
1749 prerendering and the synthesis parameter matrix in general, splitting
1750 each audio fragment into subfragments now where each subfragment uses
1751 constant pitch and filter coefficients. The volume coefficient is
1752 linearly interpolated inside a subfragment, unless
1753 --disable-interpolate-volume is set.)
1754 - fine tuning of the EG modulation parameters
1755 - improved filter cutoff calculation by adding support for the
1756 following gig parameters: Cutoff freq (used when no cutoff
1757 controller is defined), Control invert, Minimum cutoff, Velocity
1758 curve and Velocity range. The keyboard tracking now scales
1759 cutoff frequency instead of resonance.
1760 - added support for gig parameter Resonance.
1761 - fixed bug in sysex handling (patch by Juan Linietsky)
1762 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1763 which can be overridden with --enable-global-attenuation
1764 - EG fixes: made the length of "attack hold" stage more
1765 accurate. Release stage can now start before attack stage
1766 ends. Cancel release didn't work when sustain was zero. Attack
1767 time now has a minimal value to prevent clicks.
1768 - fixed pitch changes larger than one octave
1769 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1770 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1771 all modes can be altered via standard GM messages, that is CC5 for
1772 altering portamento time, CC65 for enabling / disabling portamento
1773 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1774 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1775 parameter) and crossfade
1776 - added support for the "attenuation controller threshold" gig
1777 parameter
1778 - added smoothing of volume changes caused by control change
1779 messages
1780 - sample loop parameters are now taken from the DimensionRegion
1781 instead of the wave chunk
1782 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1783 not equal to a power of two
1784 - reimplementation of the filter algorithm. The new filter is more
1785 accurate and supports all gig filter types, including bandreject
1786 and lowpass turbo.
1787 - real support for 24 bit samples - samples are not truncated to
1788 16 bits anymore
1789 - support for aftertouch (channel pressure, not polyphonic
1790 aftertouch)
1791 - LFO1 behaviour fixed (dampening from max volume instead of
1792 amplifying from 0)
1793
1794 * LSCP server:
1795 - fixed application exit on broken pipe error (fixes bug #20)
1796 - fixed the notification messages delay due to lack of
1797 network activity (fixes bug #26)
1798 - fixed parser bug which occured on space(s) within device parameters
1799 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1800
1801 * audio driver:
1802 - added aRts audio output driver (by no means RT safe)
1803
1804 * MIDI driver:
1805 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1806 messages several times instead of once
1807 - API extension for MIDI drivers which already supply exact time stamps
1808 for events (i.e. for offline rendering based MIDI drivers)
1809 - added checks for bad MIDI data
1810
1811 * linuxsampler application:
1812 - show available sampler engine types on startup
1813
1814 * general changes:
1815 - support for muting sampler channels and solo mode of the same, two new
1816 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1817 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1818 introduced for this, the behavior is the same like on a mixer console
1819 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1820 --enable-process-muted-channels which can be used to enable the
1821 processing of muted channels.
1822 - support for sostenuto pedal
1823 - support for monitoring the total number of active voices
1824 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1825 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1826 - fixed some memory management errors
1827 - fixed some concurrency problems that could lead to crashes when
1828 LSCP commands were executed
1829 - fixed crash when instrument loading failed previously on the same
1830 sampler channel (fixes bug #36)
1831
1832 Version 0.3.3 (15 July 2005)
1833
1834 * packaging changes:
1835 - fixed compilation with gcc 4.0
1836
1837 * Gigasampler format engine:
1838 - LFO preprocessing was performed even though the respective LFO was
1839 disabled by the instrument patch (minor efficiency fix)
1840 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1841 for volume ramp downs in the same fragment (needed for current voice
1842 stealing implementation) then simply inform the user with a warning
1843 about possible click sounds and reduce the volume ramp down
1844 appropriately instead of cancelling the audio device connection
1845
1846 Version 0.3.2 (24 June 2005)
1847
1848 * packaging changes:
1849 - updated autotools build files to compile on OS X
1850 (conditional compilation of CoreMIDI and MidiShare drivers)
1851 - hand-crafted assembly optimization code can be disabled with
1852 './configure --disable-asm' (definitely not recommended)
1853 - fixed 'make dist' rule to include all necessary files
1854 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1855 (due to 'dist-bzip2' automake option)
1856
1857 * Gigasampler format engine:
1858 - support for the gig parameters for "release velocity response" curves
1859 - fine tuning of the EGADSR envelope
1860 - volume of release triggered samples now depends on note-on velocity,
1861 note length and gig parameter "release trigger decay" instead of
1862 note-off velocity.
1863 - revised voice stealing
1864 (fixes crash and endless loop caused by voice stealing)
1865 - don't reset scale tuning on instrument or audio output device change
1866 - handle key group conflicts right at the beginning of each fragment
1867 instead of when the respective voice is actually launched
1868 (fixes undefined behavior if stolen voices belonged to a key group -
1869 this case was followed by a "killed voice survived" error message)
1870 - fixed minor issue with null/silence samples
1871 (those stole voices even though they don't need a voice at all which
1872 resulted in "voice stealing didn't work out" messages)
1873 - don't reset volume, pan, pitch and MIDI controller values on
1874 instrument or audio output device change
1875
1876 * LSCP server:
1877 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1878 - fixed LSCP event "CHANNEL_INFO" notification
1879 (e.g. did not notify on volume changes or MIDI program change events)
1880
1881 * linuxsampler application:
1882 - added command line parameters --lscp-addr and --lscp-port to override
1883 default IP address and port of LSCP server
1884
1885 Version 0.3.1 (24 May 2005)
1886
1887 * initial release
