Revision 3763 - (show annotations) (download)
Sun Apr 5 20:15:57 2020 UTC (3 years, 11 months ago) by schoenebeck
File size: 99468 byte(s)
* Implemented global backtraceAsString() function for debugging purposes
  (POSIX systems only, no Windows implementation yet).

* Bumped version (2.1.1.svn51).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++14 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++14 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++14).
10 - RTMath: Implemented floating point comparison methods
11 fEqual32(float,float) and fEqual64(double,double) which take the
12 expected floating point tolerances into account.
13 - Added public API C++ class "LFO", which is a cluster class encapsulating
14 all the sampler's LFO implementations to be used by 3rd party applications
15 (e.g. by Gigedit).
16 - Added int math square LFO implementation.
17 - Added int math saw LFO implementation.
18 - Added numeric complex nr sine LFO implementation.
19 - Marked class LFOTriangleDiHarmonic as deprecated
20 (will be removed in future).
21 - Added LFOAll.h which includes all LFO implementation's header files.
22 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25 SquareLFO -> LFOSquarePulse and separated the latter to its own header
26 file).
27 - Renamed type LFOSigned -> LFOTriangleSigned.
28 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29 - Using now cubic interpolation as resampling algorithm by default; and
30 linear interpolation is deprecated now.
31 - Event:Init(): memset() entire Event::Param union to zero instead of trying
32 to do that for its individual members; the latter became error prone due
33 to the union's growing complexity meanwhile.
34 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36 methods and marked the old ones as deprecated; and likewise added new
37 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38 methods and marked those old ones deprecated as well.
39 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41 - Implemented support for compressed RPN/NRPN message sequences (that is to
42 allow processing MIDI data entry messages without always having to be
43 preceded strictly by RPN/NRPN parameter selection messages on each value
44 change).
45 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46 decrement).
47 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48 MSB=127 and LSB=127) and which is disabling subsequent data
49 entry/increment/decrement CC messages.
50 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51 instrument editor.
52 - Fixed playing noise at the end of a disk stream under certain conditions.
53 - Fixed potential crash with high pitch at end of RAM playback.
54 - Added configure checks whether C++ compiler supports so called
55 'designated initializers'.
56 - Added global backtraceAsString() function for debugging purposes
57 (POSIX systems only, no Windows implementation yet).
58
59 * Real-time instrument scripts:
60 - Added method ScriptVM::setExitResultEnabled() which allows to
61 explicitly enable the built-in exit() function to optionally accept
62 one function argument; the value of the passed exit() function
63 argument will then become available by calling
64 VMExecContext::exitResult() after script execution.
65 - 64 bit support for NKSP integer scripts variables (declare $foo).
66 - Variable names, function names and preprocessor condition names must start
67 with a regular character (a-z or A-Z); starting them with a digit or
68 underscore is not allowed.
69 - NKSP parser fix: equal comparison operator "=" and not equal comparison
70 operator "#" must only accept integer operands.
71 - NKSP language: Implemented support for standard units like Hertz, seconds,
72 Bel including support for metric unit prefixes; so one can now e.g.
73 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
74 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
75 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
76 - NKSP language: Introduced "final" operator "!" which is specifically
77 intended for synthesis parameter values to denote that the synthesis
78 parameter value is intended to be the "final" value for that synthesis
79 parameter that should explicitly be used by the engine and thus causing
80 the sampler engine to ignore all other modulation sources for the same
81 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
82 variable or formula with this new "!" operator the expression is marked as
83 being "final".
84 - NKSP script editor API: Added support for detecting standard unit tokens
85 and their potential metric prefix token.
86 - NKSP language: Added support for NKSP real number literals and
87 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
88 - NKSP language: Added support for NKSP real number (floating point) script
89 variables (declare ~foo).
90 - NKSP language: Added support for NKSP real number (floating point) array
91 script variables (declare ?foo[]).
92 - Built-in script function "message()" accepts now real number argument as
93 well.
94 - Added built-in script function "real_to_int()" and its short hand form
95 "int()" for casting from real number to integer in NKSP scripts.
96 - Added built-in script function "int_to_real()" and its short hand form
97 "real()" for casting from integer to real number in NKSP scripts.
98 - Allow built-in exit() function to potentially accept real number type
99 argument as well.
100 - Built-in script functions may have a different return type depending on
101 the arguments passed to the function.
102 - Built-in script function "abs()" optionally accepts and returns real
103 number.
104 - Built-in script functions "min()" and "max()" optionally accept real
105 number arguments and return real number as result in that case.
106 - NKSP VM API: Allow units and 'final'ness to be returned as result from
107 built-in functions (added methods VMFunction::returnUnitType() and
108 VMFunction::returnsFinal() for that purpose which must be implemented by
109 built-in function implementations).
110 - NKSP language: Allow metric unit prefixes of numeric scalar and array
111 variables to be changed freely at runtime (unlike unit types like Hz etc.
112 which are still sticky, parse-time features of variables which cannot be
113 changed at runtime for the intentional sake of determinism).
114 - NKSP language: 'final' values are prohibited for array variables for now
115 (attempt causes a parsers error).
116 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
117 conditions of runtime control structures like if(), while(), select()
118 (attempt causes a parser error).
119 - NKSP VM API: Allow built-in functions to perform their own, individual
120 parse time checks of arguments going to be passed to the function at
121 runtime (added method VMFunction::checkArgs() for that purpose).
122 - NKSP language: raise parser warning if only one operand of binary
123 operators (like logical 'or' comparison) contain a 'final' value (because
124 it would always yield in a 'final' result in such cases).
125 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
126 different metric unit prefixes, which will behave as expected (e.g.
127 result of expression '1000us < 2ms' is true).
128 - NKSP language: Allow adding values with different metric unit prefixes
129 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
130 - NKSP language: Allow subtracting values with different metric unit
131 prefixes (e.g. result of expression '1ms - 20us' is '980us').
132 - NKSP language: Allow multiplying with any metric unit prefixes
133 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
134 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
135 we don't have any considerable practical use for a term like '4s^2'
136 (hence any attempt multiplying two unit types still causes parser error).
137 - NKSP language: Allow dividing by any metric unit prefixes and allow
138 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
139 yields in unit free result '8'). So this is now a way to cast units away
140 e.g. for passing the result to other expressions, certain function calls
141 or variables which are not accepting any units (or that specific unit).
142 - NKSP language: integer arrays and real number arrays can now be converted
143 to strings (e.g. for dumping their content with message() calls for
144 script debugging purposes).
145 - NKSP language: expressions and variables with units are now correctly
146 casted to strings (e.g. with message() calls).
147 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
148 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
149 floating point tolerances into account.
150 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
151 VMScalarNumberExpr::evalCastReal().
152 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
153 'VMIntArrayExpr' and 'VMRealArrayExpr'.
154 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
155 unitFactor() (runtime) methods.
156 - Built-in function "exit()" supports now returning units and 'final'ness
157 for test cases.
158 - The following built-in functions support now units as well: "abs()",
159 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
160 "real_to_int()", "int()", "int_to_real()" and "real()".
161 - Built-in functions "array_equal()", "search()" and "sort()" support now
162 real number arrays (correctly) as well.
163 - Added individual parse time checks of arguments to be passed to built-in
164 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
165 "array_equal()" and "search()" specific for their individual purposes.
166 - NKSP VM refactoring: Renamed all methods, functions and classes matching
167 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
168 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
169 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
170 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
171 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
172 isScalarNumber() -> isNumber()).
173 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
174 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
175 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
176 as convenient methods for automatically converting values to expected
177 metric value basis.
178 - Built-in function "wait()" accepts now both integers and real numbers as
179 argument.
180 - NKSP VM API cleanup: Get rid of legacy method
181 VMFunction::argType(vmint iArg) which was already superseded by its new
182 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
183 - NKSP parser: if wrong argument type was passed to a built-in function and
184 that built-in function accepts more than one data type for the argument,
185 then show all supported data types as parser error message.
186 - Built-in function "play_note()" accepts now real numbers and seconds as
187 unit type as well for its 3rd and 4th function arguments.
188 - The following built-in functions accept now real numbers as well for their
189 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
190 "change_attack()", "change_decay()", "change_release()",
191 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
192 "change_cutoff_sustain()", "change_cutoff_release()",
193 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
195 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
196 - Fixed built-in function "change_play_pos()" not having accepted metric
197 prefixes at all.
198 - Fixed the following built-in functions having misinterpreted values given
199 with unit type (for their 2nd argument) as if they were relative values
200 (that is as if they were passed without a unit type): "change_attack()",
201 "change_decay()", "change_release()", "change_cutoff_attack()",
202 "change_cutoff_decay()", "change_cutoff_release()".
203 - Fixed the following built-in functions having applied completely wrong
204 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
205 respective EGs being their modulation sink assume uint data type with
206 value range 0..1000 instead of 0.0..1.0.
207 - Added individual parse-time checks of function arguments for the following
208 built-in functions: "play_note()", "note_off()", "set_event_mark()",
209 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
210 "change_decay()", "change_release()", "change_cutoff_attack()",
211 "change_cutoff_decay()", "change_cutoff_release()",
212 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
213 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
214 "change_pan_time()".
215 - Don't abort function call if unit type was used and at the same time
216 'final' operator was omitted for the primary value argument of the
217 following built-in functions: "change_cutoff()", "change_attack()",
218 "change_decay()", "change_release()", "change_cutoff_attack()",
219 "change_cutoff_decay()", "change_cutoff_release()",
220 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
221 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
222 "change_pan_time()", instead imply 'final'ness at runtime and raise an
223 appropriate parser warning at parse time.
224 - Added built-in real number functions "round()", "ceil()", "floor()",
225 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
226 "cos()", "tan()", "asin()", "acos()", "atan()".
227 - Added built-in script real number constant "~NI_MATH_PI".
228 - Added built-in script real number constant "~NI_MATH_E".
229 - NKSP language: Allow unary '+' operator.
230 - Added built-in script functions "msb()" and "lsb()".
231 - NKSP language: Added support for RPN event handler
232 ("on rpn ... end on" in instrument scripts).
233 - NKSP language: Added support for NRPN event handler
234 ("on nrpn ... end on" in instrument scripts).
235 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
236 may be read from the new RPN/NRPN script handlers to get the (N)RPN
237 parameter that had been changed and its new value.
238 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
239 which are identifying the new (N)RPN handlers as such at script runtime.
240 - Implemented built-in script function "set_rpn()".
241 - Implemented built-in script function "set_nrpn()".
242 - Fix: built-in functions returning an array type were broken and caused a
243 crash when the built-in function's (supposed to be array) result value was
244 used by the script VM.
245 - Removed upper value constraint for 2nd argument of built-in functions
246 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
247 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
248 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
249 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
250 the LFO frequency / resonance / cutoff frequency.
251 - Reduced code involved for parsing NKSP variable declarations by using 2
252 generalized grammar rules with optional components (i.e. optional value
253 assignment and optional variable qualifiers) instead of previous linear
254 combinations of grammar rules, which also fixes some edge case.
255 - NKSP language parser: track code block locations also by a) raw byte
256 position in NKSP source code string and b) length of that code block in
257 bytes (along to the already existing code block tracking by line/column);
258 and added appropriate new members to public C++ API classes like
259 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
260 - NKSP language: Added support for 'patch' variable qualifier (capture their
261 locations and allow replacement of their assignment expression via VM C++
262 API).
263 - Fixed incorrect EG times if standard measuring unit was passed to built-in
264 functions "change_attack()", "change_decay()" or "change_release()".
265 - Fixed intermediate function result values never having reflected any
266 standard measuring unit type.
267 - Fixed re-entrant issue with function calls which caused wrong result
268 values if the same function was called multiple times in a term
269 (specifically if metric prefixes were used).
270
271 * test cases:
272 - Fixed compiler errors in test cases.
273 - Updated README for how to compile & run test cases.
274 - Updated test case
275 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
276 expected behaviour of the Mutex class implementation (recursive
277 mutex type).
278 - Added test cases for NKSP core language aspects and core built-in
279 functions.
280 - Fixed thread tests segfaulting on Linux.
281 - NKSP: Added real number test cases for built-in functions exit(),
282 int_to_real(), real(), real_to_int() and int(), as well as for the
283 plus, minus and negate language operators.
284 - Added massive amount of NKSP test cases for standard measuring units and
285 'final' operator usage cases.
286 - Added NKSP test cases for (floating point tolerance aware) real number
287 equalness / unequalness comparison.
288 - Added NKSP int array and real array tests for value assignment and
289 initialization of arrays.
290 - Added NKSP test cases for built-in functions "round()", "ceil()",
291 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
292 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
293 - Added NKSP test cases for unary '+' operator.
294 - Added NKSP test cases for core built-in variables.
295 - Added thorough NKSP test cases for variable declarations.
296
297 * GigaStudio/Gigasampler format engine:
298 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
299 behaviour for start_level_mid.
300 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
301 level (see discussion "GigaStudio LFO compatibility" on mailing list
302 from 2019-09-26 for details).
303 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
304 see discussion "GigaStudio LFO compatibility" on mailing list from
305 2019-09-26 for details).
306 - Format extension: Added support for different LFO wave forms (currently
307 either sine [default], triangle, saw or square).
308 - Format extension: Added support for LFO phase displacement (0��..360��).
309 - Format extension: Added support for flipping LFO polarity on LFO 3
310 (in the original gig format this was only available for LFO 1 and LFO 2).
311 - Format extension: Support for additional filter types:
312 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
313 bandreject 2-pole.
314 - Fixd potential crash with polynomial interpolator and max. pitch.
315 - If minimum cutoff is defined, remap cutoff controller CC values to really
316 span the entire possible cutoff range (and avoiding a dead controller
317 zone).
318 - Implemented support for loading instrument scripts with 'patch' variables
319 (by patching these script variables with potentially overridden ones by
320 gig Instrument).
321
322 * SFZ format engine:
323 - Fixed support for regions with loccN/hiccN conditions on more than one
324 MIDI controller.
325
326 * Benchmarks:
327 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
328 algorithm (since result of 2nd run was not accumulated).
329 - Added benchmark for saw wave (benchmarks/saw.cpp).
330 - Added benchmark for sine wave (benchmarks/sine.cpp).
331 - Added benchmark for square wave (benchmarks/square.cpp).
332 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
333 which are large enough on modern systems.
334
335 Version 2.1.1 (27 Jul 2019)
336
337 * Real-time instrument scripts:
338 - Fixed behavior of built-in NKSP functions change_sustain(),
339 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
340 and change_cutoff_release().
341
342 * general changes:
343 - Only play release trigger samples on sustain pedal up if this behaviour
344 was explicitly requested by the instrument (otherwise only on note-off).
345 - Fixed compiler warnings.
346 - Fixed compilation error when cross-compiling to Mac.
347 - FX Sends: Provide more useful error messages on routing problems
348 (see bug #169).
349 - LSCP doc: Be more clear describing the two distinct approaches
350 of using external vs. internal effects (see bug #169).
351 - "optional" class: Fixed comparison operators.
352
353 * Gigasampler/GigaStudio format engine:
354 - Format extension: If requested by instrument then don't play release
355 trigger sample on note-off events.
356
357 * SFZ format engine:
358 - Fixed memory leak when releasing samples
359 (fixes bug #307, patch by Jacek Roszkowski)
360 - Fixed potential crash when a sample is shared by more than one region
361 (fixes bug #308, patch by Jacek Roszkowski).
362 - Opcode 'sample': Added support for built-in sample '*silence'
363 (fixes bug #310, patch by Jacek Roszkowski).
364
365 Version 2.1.0 (25 Nov 2017)
366
367 * SFZ format engine:
368 - added support for <global>, <master> and #define (patch by Alby M)
369 - Removed code duplication in SFZ file loading code.
370 - Added support for sfz extension opcode 'script' which may be used to
371 load real-time instrument script file (NKSP script language).
372 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
373 - Fixed unintended volume fade-in of voices under certain conditions.
374 - sfz parser: allow missing space between header and opcode
375
376 * Gigasampler/GigaStudio format engine:
377 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
378 cutoff settings.
379 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
380 all if an up-pitch of more than 40 semi tones was requested (I don't
381 think there is any stock gig sound that requires this behavior to
382 resemble its original sound).
383 - Added support for controlling whether the individual EGADSR stages may
384 be aborted (as LinuxSampler extension to the original GigaStudio 4
385 format).
386
387 * general changes:
388 - fixed printf type errors (mostly in debug messages)
389 - use unique_ptr instead of auto_ptr when building with C++11
390 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
391 allowing to sort data efficiently in real-time safe manner.
392 - RTList class: added methods for moving/inserting elements to arbitrary
393 position within a list.
394 - RTList class: added method fromPtr() for creating an Iterator object from
395 a raw element pointer.
396 - Attempt to partly fix resetting engine channels vs. resetting engine, an
397 overall cleanup of the Reset*(), ConnectAudioDevice(),
398 DisconnectAudioDevice() API methods would still be desirable though,
399 because the current situation is still inconsistent and error prone.
400 - Active voices are now internally grouped to "Note" objects, instead of
401 being directly assigned to a keyboard key. This allows more fine graded
402 processing of voices, which is i.e. required for certain instrument
403 script features.
404 - Fix: Release trigger voices were not spawned on sustain pedal up
405 (CC #64) events.
406 - Fix: Release trigger voices can now also distinguish correctly between
407 note-off and sustain pedal up events.
408 - All engines: Increased ramp speed of volume smoother and pan smoother
409 (while slow rate of crossfade smoother is preserved) to allow quick
410 volume and pan changes by instrument scripts for instance.
411 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
412 properly and thus were ignored for certain uses.
413 - Added new C++ API method
414 VirtualMidiDevice::SendChannelPressureToSampler().
415 - windows, 32-bit: fixed potential crashes by making sure the stack in
416 sub threads is 16-byte aligned
417 - fixed numerous compiler warnings
418 - Fixed invalid (note-on) event ID being assigned to new Note objects.
419 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
420 fixes potential undefined behavior.
421 - Fixed Note object leak when triggering notes on keys which did not
422 have a valid sample mapped (fixes bug #252).
423 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
424 - linuxsampler binary fix: option --create-instruments-db ignored
425 subsequent optional argument due to glibc's implementation oddity
426 which expects a "=" sign, but no space between them.
427
428 * packaging changes:
429 - removed unnecessary dependency to libuuid
430 (originated by libgig's usage of it)
431 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
432 auto detect whether it (sh/c)ould output its messages in color.
433 - Debian: Fixed packaging error about invalid "Source-Version"
434 substitution variable.
435 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".

437 linuxsampler with instruments DB support.
438
439 * Real-time instrument scripts:
440 - Implemented scheduler for delayed MIDI events and for suspended scripts.
441 - Built-in script function "wait()": implemented support for function's
442 "duration-us" argument, thus scripts using this function are now
443 correctly resumed after the requested amount of microseconds.
444 - Built-in script function "play_note()": implemented support for
445 function's "duration-us" argument, thus notes triggered with this
446 argument are now correctly released after the requested amount of
447 microseconds.
448 - Fix: script events were not cleared when engine channel was reset,
449 potentially causing undefined behavior.
450 - Fixed crash which happened when trying to reference an undeclared
451 variable.
452 - Built-in script function "play_note()": Added support for passing
453 special value -1 for "duration-us" argument, which will cause the
454 triggered note to be released once the original note was released.
455 - Instrument script classes now exported with the liblinuxsampler C++ API.
456 - Added new API method ScriptVM::syntaxHighlighting() which provides
457 a convenient syntax highlighting backend for external instrument
458 script editor applications.
459 - Added new C++ API class "ScriptVMFactory".
460 - Extended parser issues to provide not only first line and first
461 column, but also last line and last column of issue (thus marking
462 the precise span of the issue within the source code).
463 - Reload script automatically after being modified by an instrument
464 editor.
465 - NKSP language grammar correction: allow empty event handler bodies
466 like "on note end on".
467 - Implemented built-in script function "change_vol()".

472 - Implemented built-in script function "event_status()".
473 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
474 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
475 "event_status()" function.
476 - NKSP language: Added support for bitwise operators ".or.", ".and."
477 and ".not.".
478 - NKSP language scanner: Fixed IDs matching to require at least one
479 character (i.e. when matching function names or variable names).
480 - NKSP language scanner: disabled unusued rules.
481 - Fixed behavior of play_note() and note_off() functions which must
482 be distinguished engine internally from "real" MIDI note on/off
483 events in order to avoid misbehaviors like hanging notes.
484 - Implemented built-in script variable "$KSP_TIMER".
485 - Implemented built-in script variable "$NKSP_REAL_TIMER".
486 - Implemented built-in script variable "$NKSP_PERF_TIMER".

490 - NKSP language fix: division expressions were evaluated too often.
491 - NKSP language fix: string concatenation operator was right
492 associative instead of left (to right).
493 - NKSP language correction: allow empty statements in entire language
494 (i.e. "if end if").
495 - Implemented built-in script function "stop_wait()".

506 - Implemented built-in script function "change_attack()".
507 - Implemented built-in script function "change_decay()".
508 - Implemented built-in script function "change_release()".
509 - Fixed all change_*() built-in script functions to apply their
510 synthesis parameter changes immediately in case the respective note
511 was triggered at the same time, instead of scheduling the parameter
512 change, especially because it would cause some parameter types's
513 changes either to be ramped (i.e. change_vol()) or other types even
514 to have not effect at all (i.e. change_attack()).
515 - Implemented built-in script function "sh_left()".
516 - Implemented built-in script function "sh_right()".
517 - Implemented built-in script function "min()".
518 - Implemented built-in script function "max()".
519 - NKSP Fix: "init" event handler was not always executed when a script
520 was loaded.
521 - NKSP built-in wait() script function: abort script execution if
522 a negative or zero wait time was passed as argument (since this is
523 a common indication of a bug either of the script or even of the
524 engine, which could lead to RT instability or even worse).
525 - ScriptVM: Implemented automatic suspension of RT safety
526 threatening scripts.
527 - Provide more user friendly error messages on syntax errors.
528 - Fixed NKSP parser warning "Not a statement" when assigning an
529 initializer list to an array variable.

536 - Implemented built-in script function "change_vol_time()".
537 - Implemented built-in script function "change_tune_time()".
538 - Implemented built-in script function "fade_in()".
539 - Implemented built-in script function "fade_out()".
540 - Fixed acceptance of wrong data type of parameters passed to built-in
541 script functions "change_vol()", "change_tune()", "change_pan()",
542 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
543 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
544 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
545 - Added built-in script function "get_event_par()" and implemented some
546 of its possible parameter selections.
547 - Added built-in script function "set_event_par()" and implemented some
548 of its possible parameter selections.
549 - Fixed a bunch of scheduler time related bugs.
550 - Fixed polyphonic variables not being reset to zero after usage.
551 - Built-in "ignore_event()" function: argument is now optional, like with
552 built-in function "ignore_controller()".
553 - Implemented built-in script function "change_velo()".
554 - Implemented built-in script function "change_note()".
555 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
556 intuitive behavior if used in combination with "change_vol_time()" or
557 "change_tune_time()" respectively: now tuning/volume changes are only
558 assigned (without delay) immediately to a new note if the respective
559 timing function has not been called before, otherwise the volume/tuning
560 changes are automatically faded (before, only the event's time stamp was
561 relevant).
562 - Implemented built-in script function "array_equal()".
563 - Implemented built-in script function "search()".
564 - Implemented built-in script function "sort()".
565 - NKSP Fix: Never suspend "init" event handlers.
566 - Implemented built-in script function "same_region()" (currently only
567 available for gig format engine).
568 - Added built-in script constant "$NKSP_LINEAR".
569 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
570 - Implemented built-in script function "change_vol_curve()".
571 - Implemented built-in script function "change_tune_curve()".
572 - built-in "play_note()" function now supports a sample playback start
573 offset with argument 3, where special value -1 means to use the regular
574 sample offset as defined by the instrument file.
575 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
576 - Built-in variable $EVENT_NOTE is now a read-only variable.
577 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
578 - built-in "play_note()" function now accepts -2 for its fourth argument
579 (note duration) which means the life time of the note shall be sticked
580 to the requested note number of argument 1.
581 - Fix: built-in "play_note()" function now returns 0 as result value if
582 -1 was passed for its fourth argument (note duration) and the respective
583 parent note is already gone.
584 - Implemented built-in script function "change_play_pos()".
585 - NKSP language: Added support for user declared const array variables.
586 - NKSP language: Raise parser warning if array variable is accessed with
587 an index that exceeds the array's size.
588 - NKSP language fix: Unknown characters were not handled correctly.
589 - NKSP language: Added support for "synchronized .. end synchronized"
590 code blocks.
591 - Implemented built-in script function "abort()" which allows to abort
592 another script handler by passing its callback ID.
593 - Fixed potential memory access bug and potential undefined behavior of
594 "init" event handlers.
595 - Print a time stamp along to each call of built-in function "message()".
596 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
597 to retrieve all code blocks filtered out by the preprocessor.
598 - Added built-in script function "fork()".
599 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
600 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

602 - Added built-in script function "callback_status()".
603 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
604 - Added built-in constant $CALLBACK_STATUS_QUEUE.
605 - Added built-in constant $CALLBACK_STATUS_RUNNING.
606 - Removed max. value limitation of built-in functions "change_attack()",
607 "change_decay()" and "change_release()" to i.e. allow passing 2000000
608 for doubling the respective time.
609 - NKSP script editor syntax highlighting API: Fixed app termination due
610 to a lexer start condition stack underrun.
611 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
612 USE_CODE_IF_NOT() preprocessor statements.
613 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
614 can be set to disable all subsequent built-in "message()" function calls
615 on preprocessor level.
616 - Implemented built-in script function "change_sustain()".
617 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

633 is now optional, if it is missing, then a default location is used.
634 - Added support for scanning SFZ (.sfz) files.
635 - Added support for scanning Sound Font (.sf2) files.
636 - Fixed undefined DB transaction behavior.

650 - minor Makefile fix for building lscpparser when build and source
651 directories are separate
652 - Mac OS X: made it possible to specify plugin installation dir to
653 configure
654 - Mac OS X: Makefile fix for the install-strip target
655 - fixed compilation with gcc 4.7
656 - fixed configure script error with old autoconf versions
657 - lsatomic.h: use gcc provided atomic functions if building with
658 gcc 4.7 and C++11
659 - modernized configure script
660 - fixed linkage error when building with
661 LDFLAGS="-Wl,--no-undefined" (#190)
662 - fixed compilation with Clang 3.2
663 - removed usage of deprecated Automake variable INCLUDES
664 - fixed building with C++11
665 - build fix: ChangeFlagRelaxed.h was missing in makefile
666 - build fix: libsndfile compiler flags were missing in some
667 makefiles
668 - fix for building with bison 3.0 (#202)

670 on the process's main thread
671 - fixed build error on newer MinGW
672 - support building with older jack versions

676 in order to get rid of warnings from automake 1.14
677
678 * general changes:
679 - Refactoring: moved the independent code from
680 the Gigasampler format engine to base classes
681 - command line option '--profile' is currently disabled, since the
682 respective profiling code is currently broken
683 - Introduced support for optional environment variable
684 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
685 where the sampler shall look for instrument editor plugins
686 (patch by Luis Garrido, slightly modified).
687 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
688 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
689 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
690 note (in this implementation of the sampler its simply hard routed to
691 the 1st effect send of the sampler channel, no matter what the actual
692 effect type is)
693 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
694 note (in this implementation of the sampler its simply hard routed to
695 the 2nd effect send of the sampler channel, no matter what the actual
696 effect type is)
697 - implemented support for internal LADSPA effects
698 - raised limit of program change queue from 100 to 512
699 (as suggested by Alex Stone)
700 - implemented sine LFO, pulse LFO and saw LFO
701 - experimental support for per voice equalization
702 - added command line option --exec-after-init
703 - Introduced new C++ API method:
704 EngineChannel::InstrumentFileName(int index)
705 allowing to retrieve the whole list of files used for the loaded
706 instrument on an engine channel (a.k.a. part). Some GigaStudio
707 instruments for example are splitted over several files like
708 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
709 - Added new C++ API method Sampler::GetGlobalMaxVoices().
710 - Added new C++ API method Sampler::GetGlobalMaxStreams().
711 - Added new C++ API method Sampler::SetGlobalMaxVoices().
712 - Added new C++ API method Sampler::SetGlobalMaxStreams().
713 - Various "const" and "restrict" optimizations.
714 - all engines: add pan CC value to instrument pan parameter before
715 applying panning, instead of using two separate pan functions in
716 series (#182)
717 - added a lock guard class for exception safe mutex handling and
718 used it everywhere appropriate
719 - Immediately apply scale tuning changes to active voices.
720 - Exposed scale tuning to C++ API (along to the already existing standard
721 SysEx way).
722 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
723 and broken for ppc64. (Seq_cst loads and stores are actually not
724 used in LS, so the bug wasn't noticable.)
725 - lsatomic.h: added ARMv7 support
726 - Added support for multiple MIDI input ports per sampler channel (and
727 added various new C++ methods for this new feature / design change, old
728 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
729 as deprecated but are still there and should provide full behavior
730 backward compatibility).
731 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
732 unsafe and caused compilation error with clang 2.x).
733 - Bugfix: only process the latest MIDI program change event.
734 - Introducing the LSCP shell, which provides convenient control of the
735 sampler from the command line by providing LSCP aware features.
736 - VirtualMidiDevice: Added support for program change.
737 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
738 - VirtualMidiDevice: Added support for pitch bend.
739 - Aftertouch: extended API to explicitly handle channel pressure and
740 polyphonic key pressure events (so far polyphonic pressure was not
741 supported at all, and channel pressure was rerouted as CC128 but not
742 used so far).
743 - Added initial support for real-time instrument scripts. The script VM
744 code is shared by all sampler engine implemementations, however only the
745 gig file format currently provides support for storing instrument scripts
746 (as LinuxSampler extension to the original GigaStudio 4 format).
747
748 * Gigasampler format engine:
749 - implemented the "round robin keyboard" dimension
750 - fixed round robin and random dimensions for cases when number of
751 dimension zones is not a power of two

753 key
754 - bugfix: pitch LFO controller "internal+aftertouch" was broken
755 - bugfix: filter keyboard tracking was broken
756 - filter performance fix (an unnecessary copy was made of the
757 filter parameters in each sub fragment)
758 - handle special case when pan parameter in gig file has max or
759 min value
760 - Exclusive Groups: don't ever stop voices of the same note,
761 doesn't sound naturally with a drumkit
762 - fixed EG1 modulation when attack or release is zero
763 - Fixed support for 'aftertouch' attenuation controller.
764 - Fixed crash that happened with velocity split sounds under certain
765 conditions (see also previous commit on libgig).
766 - fixed behaviour of filter LFO
767
768 * SFZ format engine:
769 - Initial implementation (not usable yet)

778 multiple regions
779 - added some opcode aliases, like loopmode for loop_mode, to be
780 more compatible
781 - added support for trigger=release and rt_decay

798 - added support for loop_mode=one_shot
799 - fixed playback of 16 bit wav files on big endian CPUs
800 - added support for Ogg Vorbis sample files
801 - use loop markers from sample file if loop_start and loop_end are
802 not set in sfz file
803 - implemeted filters. Filter types: lowpass, bandpass, bandreject
804 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
805 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
806 cutoff_cc, cutoff_chanaft.
807 - bugfix: zero ampeg_sustain didn't work

996 the driver will automatically connect to other CoreMIDI clients' ports
997 (e.g. external MIDI devices being attached to the Mac)
998 - added support for MIDI note on velocity filter
999 - CoreMIDI: fixed memory deallocation error
1000 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
1001 virtual keyboards in frontends / instrument editors being stuck.

1135 a crash, or give "Handing back unknown region" error messages
1136 - bugfix: calling SET VOICES (which Fantasia does on start and
1137 refresh) could cause instruments to be unloaded

1170 crashes and noise on such transitions).
1171 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1172 (fixes #208)
1173 - Fixed bug in LSCP grammar definition which caused a statement like
1174 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1175 practically irrelevant, however it caused problems with the new LSCP
1176 shell's auto completion feature).
1177 - Fixed MIDI program change messages being ignored if quickly executed
1178 after each other (fixes #231).
1179
1180 Version 1.0.0 (31 July 2009)
1181
1182 * packaging changes:
1183 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1193 - minor fix in configure for mmsystem.h detection on MinGW
1194 - Windows: look for editor plugins and Fantasia using base
1195 directory of liblinuxsampler dll (look in the same directory and one
1196 directory above)
1197 - configure script fix: removed unconditional use of SSE
1198 - fixed building with sqlite installed in a non-standard directory
1199 - when cross-compiling, don't try to create instruments.db
1200 - fix for new mingw-w64 version, which has usleep
1201
1202 * general changes:
1203 - bugfix: on some POSIX systems instrument editor plugins refused to
1204 load as we used a non-portable Linux specific struct field
1205 (fixes bug #70, patch by Ronald Baljeu)
1206 - fixed endless loop which occured when loading an instrument editor
1207 plugin DLL on Windows systems failed
1208 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1209 - optimized the SynchronizedConfig class so it doesn't wait
1210 unnecessarily long after an update

1212 events (e.g. to highlight the pressed keys on the virtual keyboard
1213 of gigedit)
1214 - added support for triggering notes by instrument editors (see above)
1215 - be verbose on DLL load errors (on Linux)
1216 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1217 is only used by very few systems, most pick the int math
1218 implementation, which is usually faster)
1219 - fixes for audio drivers with varying buffer sizes
1220 - experimental support for running LinuxSampler as a DSSI, LV2 and
1221 VST plugin
1222 - notification events for stream/voice count statistics are now sent
1223 only when there are actual changes

1225 multi-core and multi-cpu systems
1226 - maximum voices and disk streams can now be altered at runtime
1227 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1228 - automatic stacktrace mechanism is now turned off by default and can
1229 be switched on by command line option "--stacktrace" (the automatic
1230 stacktrace mechanism seems to be broken on most systems at the moment)
1231 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1232 a pointer to the launched InstrumentEditor object
1233 - added optional 3rd party user data parameter for following
1234 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1235 InstrumentEditor::Launch(),
1236 InstrumentManager::LaunchInstrumentEditor()
1237 - theoretical fix: made SynchronizedConfig follow C++0x memory
1238 model more strictly
1239 - fixes for using large audio device buffers
1240 - Windows: add the installation directory to the DLL search path
1241 when loading an editor plugin (solves problems with VST and

1244
1245 * audio driver:
1246 - removed the nonsense audio channel constraint (which was hard coded to
1247 max. 100 audio channels) for most audio drivers
1248 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1249 opposed to the LSCP specs
1250 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1251 reflected the wrong value
1252 - fixed a memory management bug in ASIO driver
1253 - Makefile fix: JACK_CFLAGS wasn't used
1254 - JACK: use jack_client_open instead of the deprecated
1255 jack_client_new
1256 - added (experimental) CoreAudio driver

1261 win64)
1262 - VST: added support for sample rate and buffer size changes
1263 - VST: close editor (Fantasia) when the VST is removed
1264 - VST: avoid opening Fantasia more than once for each VST instance
1265 - VST: export main function as "main" on Linux too (fix for
1266 energyXT)
1267 - VST: changed number of output channels from one stereo to 16
1268 stereo
1269 - added channel routing, fxsends and midi maps to the settings
1270 stored in the plugin state
1271 - performance optimization of AudioChannel::MixTo() and
1272 AudioChannel::CopyTo() methods using GCC vector exensions
1273 (if available)
1274 - ASIO fixes: avoid initializing the device twice, avoid throwing
1275 exception when getting parameters from a disconnected device
1276
1277 * MIDI driver:
1278 - added JACK MIDI driver
1279 - dispatch bank select as ordinary CC as well, the user might seriously
1280 want to (mis)use it for some purpose ("fixed" in all current MIDI
1281 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1282 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1283 CoreMidi or AU
1284 - fixed mingw-w64 compilation error in MME driver
1285 - made program change handling in MIDI thread real-time safe by
1286 moving the logic to a non-RT thread
1287 - fixed minor memory leak in ALSA driver
1288
1289 * instruments database:
1290 - avoid time consuming samples scanning when adding instruments
1291 to the instruments database
1292 - added support for handling lost files in the instruments database
1293 - Implemented option for adding instruments in separate directories
1294 in the instruments database
1295 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1296 - work-around for missing fnmatch function on Windows to make
1297 instrument database compilable
1298 - added instrument database support on Windows
1299 works with both standalone mode and VST plugin.
1300 the instruments DB file is located in
1301 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1302 databases for each windows user
1303 if no DB is present it automatically creates the .linuxsampler subdir
1304 and then creates an empty DB
1305 - fixed recursive import, which was broken on Windows
1306
1307 * Gigasampler format engine:
1308 - fixed a memory leak that could happen when a channel was deleted
1309 while notes were playing
1310 - made it possible to load an instrument even if the audio thread
1311 isn't running
1312 - added partial support for the "Controller Triggered" MIDI rule,
1313 enough for piano gigs with pedal noise samples
1314 - minor fix: only mark FX sends as being modified if really the
1315 respective FX send MIDI controller was used
1316 - added support for GM global device volume SysEx message
1317 (can be selected at compile time to either apply globally to the
1318 whole sampler [default] or only to the sampler channels that are
1319 connected to the respective MIDI input port the SysEx message arrived
1320 on)
1321 - bugfix: notes triggered at position 0 in the audio buffer were
1322 sometimes wrongly killed in the same buffer, causing no sound to
1323 be played
1324 - added support for chromatic / drumkit mode Roland GS Sysex message
1325 which is usally used to switch a part between chromatic sounds and
1326 drumkit sounds (as opposed to their common default setting of MIDI
1327 part 10 being a drumkit part and all other ones chromatic parts), in
1328 LS however one can switch between the first 16 MIDI instrument maps
1329 defined for the sampler
1330 - made it possible to create multiple sample channels even if the
1331 audio thread isn't running
1332 - fixed crash when removing channel with active voices (#116)
1333 - bugfix: on sample reference changes (instrument editor), only
1334 un-cache the respective sample if it's really not used by any
1335 sampler engine anymore
1336 - re-cache samples in case they were changed by an instrument editor,
1337 e.g. when a sample was added while playing (#82)
1338 - fixed hanging notes which occured when note-off event had the exact
1339 same time stamp as the voice's note-on event and occured both in the
1340 same audio fragment cycle (fixes bug #112)
1341 - added support for the "fine tune" and "pitch bend range"
1342 instrument-level gig parameters
1343 - fixed minor artifacts in pitch bend handling
1344 - added support for GS Reset SysEx message
1345 - allow gig files to use unlimited downward pitch shifting
1346 - added a limit check for upward pitch shifting
1347 - bugfix: sometimes, when playing a note twice fast, the second
1348 note was silent
1349 - fixed crash happening when a pitch bend event arrived at the
1350 same time a new instrument was loading
1351
1352 * LSCP server:
1353 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1354 react on MIDI data arriving on certain sampler channels (so far only
1355 Note-On and Note-Off events are sent via this LSCP event)
1356 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1357 react on MIDI data arriving on certain MIDI input devices (so far only
1358 Note-On and Note-Off events are sent via this LSCP event)
1359 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1360 SET DB_INSTRUMENT FILE_PATH
1361 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1362 frontends to send MIDI messages to specific sampler channel
1363 - added two additional fields to GET FILE INSTRUMENT INFO command -
1364 KEY_BINDINGS and KEYSWITCH_BINDINGS
1365 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1366 was incorrect
1367 - Optimized the retrieval of the MIDI instrument mappings
1368 - added new LSCP command "SET VOICES" to globally alter the maximum
1369 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1370 be triggered respectively
1371 - added new LSCP command "SET STREAMS" to globally alter the maximum
1372 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1373 which will be triggered respectively
1374 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1375 a gigedit file dialog is opened)
1376 - close all connections when LSCPServer is deleted
1377 - hard close of all sockets on exit
1378 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1379 driver
1380
1381 * Bug fixes:
1382 - fixed a crash which occurs when removing a sampler channel waiting
1383 to start instrument loading after another channel
1384 - fixed a crash which occurs when removing a sampler channel with
1385 instrument loading in progress (bug #113)
1386 - fixed termination caused by uncaught exception when adding MIDI
1387 instrument with PERSISTENT load mode
1388 - fixed possible iterator invalidations when resetting the sampler
1389 - fixed memory leaks when issuing the following LSCP commands:
1390 GET AUDIO_OUTPUT_DRIVER INFO
1391 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1392 GET MIDI_INPUT_DRIVER INFO
1393 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1394 - fixed possible compilation error when sqlite is not present
1395 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1396 - fixed crash when changing the audio output device of a sampler
1397 channel with loaded instrument and start playing notes
1398 - fixed endless loop in Engine::SuspendAll() (bug #120)
1399 - fixed a low-level atomic load function that was broken on 64-bit
1400 PowerPC, which probably could cause crashes on that platform
1401 - fixed a memory management error which could cause a crash when a
1402 plugin was unloaded
1403 - bugfix: two private structs had the same name, which could cause
1404 problems if the linker chose the wrong constructor
1405 - fixed low-level ConditionServer usage bug that caused lockups on
1406 Windows
1407
1408
1409 Version 0.5.1 (6 December 2007)
1410
1411 * packaging changes:
1412 - added autoconf checks for pthread library
1413 - added autoconf check for pthread bug found on certain NPTL-enabled
1414 glibc versions (see Gentoo bug report #194076)
1415 - added autoconf checks for MS Windows
1416
1417 * general changes:
1418 - bugfix: the thread used by an editor plugin didn't die when the
1419 editor closed
1420 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1421 out all the space. operator--() did not apply size_mask after
1422 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1423 order to avoid problems with the _NonVolatileReader functions.
1424 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1425 GetWriteSpace(). Since this function is currently only used in
1426 the stream's qsort() compare function, it didn't trigger any
1427 bugs.
1428 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1429 24bit mode too. Faster method to read 24bit words on little
1430 endian machines (x86): replaced 3 byte reads + shifts with a 1
1431 unaligned 32bit read and shift
1432 - experimental support for MS Windows (MIDI input via MME, AUDIO
1433 output via ASIO)
1434 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1435 - support for monitoring the total number of active disk streams
1436 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1437 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1438
1439 * AUDIO driver:
1440 - added Windows ASIO low latency audio driver
1441
1442 * MIDI driver:
1443 - added MME Windows MIDI driver
1444
1445 * LSCP server:
1446 - added support for Windows style path / filenames, however with
1447 forward slash path separators instead of backslash
1448 (i.e. "C:/foo/bar.gig")
1449 - allow naughty liblscp to send non-string device parameters within
1450 apostrophes as well
1451 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1452 "LIST FILE INSTRUMENTS <file>" and
1453 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1454 about an arbitrary instrument file on the system where the sampler is
1455 running on
1456
1457 Version 0.5.0 (15 October 2007)
1458
1459 * packaging changes:
1460 - config.h is not going to be installed along with liblinuxsampler's
1461 API header files anymore
1462 - only the API relevant header (and source) files will be exported to
1463 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1464 - added completely new XCode project files for Mac OSX which is now
1465 capable to execute our autoconf environment, thus no need anymore
1466 to maintain the compile time configuration file (osx/version.h) for
1467 OSX manually (patch by Toshi Nagata)
1468 - fixed buggy boolean --enable-foo / --disable-foo configure script
1469 parameters
1470 - global.h now only covers global definitions that are needed for the
1471 C++ API header files, all implementation internal global definitions
1472 are now in global_private.h
1473 - atomic.h is not exposed to the C++ API anymore
1474 - no need to include config.h anymore for using LS's API header files
1475 - fixed warnings in API doc generation
1476
1477 * general changes:
1478 - replaced the old, confusing MIDI program change mechanism by a
1479 flexible MIDI instrument mapper which allows to map arbitrary
1480 (MIDI bank, MIDI program) pairs with arbitrary
1481 (engine type, instrument file, file index) triplets which will be
1482 loaded on the respective channel when such MIDI program change
1483 messages arrive, beside that, each entry allows to define a life-time
1484 strategy for the instrument, so the user can define whether the
1485 instrument should i.e. be permanently loaded (to be able to switch
1486 quickly among sounds) or i.e. loaded just on demand when the
1487 respective program change arrives (to safe RAM space), as well as a
1488 global volume factor for each entry, so the user can adjust the volume
1489 dynamic of his mapped instrument collection without having to modify
1490 the instrument files, also one can manage arbitrary amount of such
1491 MIDI instrument maps and assign each sampler channel individually
1492 a certain map, so that i.e. separation of normal instruments and
1493 drumkits is possible
1494 - new notification events for tracking changes to audio/MIDI devices,
1495 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1496 - sampler was limited to load max. 200 instruments in the background
1497 due to a constant size RingBuffer FIFO which is now replaced by a
1498 dynamic (unlimited) size std::list FIFO
1499 - added FX sends, these allow to route audio signals to arbitrary audio
1500 output channels for being processed by external effect processors
1501 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1502 controllers
1503 - global (sampler wide) volume can now be controlled at runtime
1504 - Implemented new, improved notification system
1505 - fixed compilation errors regarding OSX
1506 (patch by Toshi Nagata)
1507 - implemented instruments database
1508 - added support for escape sequences to the instruments database
1509 - added highly experimental support for on-the-fly instrument editing
1510 within the sampler's process (by using instrument editor plugins),
1511 you'll notice the new "Registered instrument editors:" message on
1512 startup, added a new LSCP command:
1513 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1514 to spawn a matching instrument editor for the instrument on the
1515 given sampler channel, the plugin path can be overridden at compile
1516 time with ./configure --enable-plugin-dir=/some/dir
1517 - added experimental code for synchronizing instrument editors hosted
1518 in the sampler's process to safely edit instruments while playing
1519 without a crash (hopefully) by either suspending single regions
1520 wherever possible or if unavoidable whole engine(s)
1521 - fixed several issues in fundamental "Thread" class: set scheduling
1522 policy and priority on thread level, set a minimum stack size for
1523 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1524 threads simply inherited properties of starting thread instead of
1525 setting their own policy and priority
1526 - minor fix in our automatic stack trace mechanism on crashes, the
1527 main process did not wait for the stack trace process to finish
1528 its output
1529 - fixed some minor memory leaks
1530 - reenabled assembly features support, at the moment only for
1531 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1532 - minor assembly fix in x86 features detection (don't use the PIC
1533 register, to avoid relocations in the text segment at runtime)
1534 - POSIX callback functions of Thread.h are hidden
1535
1536 * MIDI driver:
1537 - dispatch bank select (MSB and LSB) messages
1538
1539 * audio driver:
1540 - the ALSA audio output driver parameters now reflect the correct
1541 parameter value ranges for the respective selected sound card
1542 (patch by Till Wimmer, a bit fixed and extended)
1543
1544 * Gigasampler format engine:
1545 - if a filter is used and EG2 finishes before EG1, let the voice
1546 die when EG2 has finished (this fixes a problem with clicks and
1547 voice starvation for some gigs)
1548 - playback is no longer disabled during instrument loading
1549 - all notes playing on a channel that changes its instrument keep
1550 playing with the old instrument until they get a note off
1551 command
1552 - EG fix: a release value of zero could cause noises or crash
1553 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1554 - EG fine tuning: when attack is zero the EG starts at a level
1555 above max sustain level, which means that there is a decay phase
1556 even if sustain is 100%
1557 - more EG fixes: the level could sometimes go below zero and cause
1558 noises or crashes
1559 - minor fix of EGDecay (patch by Toshi Nagata)
1560 - fixed compiler error when --enable-override-filter-type was
1561 supplied to the configure script (fixes #46)
1562 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1563 instead of a fix value
1564 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1565 127 (solo mode) only kill voices if the respective mode really
1566 changed
1567
1568 * LSCP server:
1569 - fixed compile time error for old Bison versions
1570 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1571 - parser now supports extended ASCII character set
1572 (up to ASCII code 255, i.e. includes now umlauts and accents)
1573 - filename arguments in LSCP commands now allow to use escape
1574 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1575 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1576 code value like \xf2) (fixes bug #24)
1577 - the following LSCP commands now also support escape sequences for at
1578 least one of their text-based parameters (i.e. name, description):
1579 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1580 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1581 "SET DB_INSTRUMENT_DIRECTORY NAME",
1582 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1583 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1584 "FIND DB_INSTRUMENT_DIRECTORIES"
1585 - returns verbose syntax errors (line and column where syntax error
1586 occured, the unexpected character and the actually expected, possible
1587 character(s), the latter only if less than 5 possibilities)
1588 - made sure that LSCP syntax is not affected by gigedit locale
1589 settings
1590 - bugfix regarding strings parameter lists: all comma separated lists
1591 of strings were treated as being one string containing commas
1592 (fixes #57)
1593
1594 * Bug fixes:
1595 - fixed crash occurring on certain LSCP scripts (Bug 39)
1596 - another thread safety fix for lscp "load engine" and "set
1597 channel audio output device"
1598 - fixed a crash which occurs when reassigning the same engine
1599 on a sampler channel with connected MIDI device
1600 - fixed a crash which occurs when changing the number of ports of a MIDI
1601 device connected to a sampler channel to number less then or equal
1602 to the index of the port to which the sampler channel is connected.
1603 - The previous bindings were not been disconnected when altering
1604 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1605 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1606 - The active stream/voice count statistic was incorrect.
1607 - notification events were not been sent for some sampler
1608 channel changes
1609 - added default min and max values to restrict the number of allowed
1610 audio output channels and MIDI input ports
1611 - the connection to the PCM interface is now closed when destroying
1612 an audio output device
1613 - files with slash in their path or filename could not be loaded
1614
1615 * test cases:
1616 - updated and fixed (haven't been touched in a while)
1617
1618 Version 0.4.0 (24 November 2006)
1619
1620 * packaging changes:
1621 - changed deprecated copyright attribute to license; added ldconfig
1622 to post-(un)install steps; added devel package for liblinuxsampler;
1623 to linuxsampler.spec (RPM)
1624 - install necessary development header files for allowing 3rd party
1625 applications to link against liblinuxsampler
1626 - liblinuxsampler's API documentation can be generated with 'make docs'
1627 (Doxygen required)
1628 - added benchmark to automatically detect the best triangle LFO
1629 implementation (currently either an integer math solution or a
1630 di-harmonic approximation), automatic detection can be overriden
1631 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1632 configure script argument though (mandatory for cross-compilation)
1633 - do not automatically pick optimized gcc flags if the user already
1634 provided some on his own (as CXXFLAGS)
1635 - added compile time option to disable processing of All-Notes-Off MIDI
1636 messages
1637 - added compile time options to allow disabling the various audio and
1638 MIDI drivers
1639 - fixed automatic GCC CPU switch detection on PPC
1640 (patch by Ebrahim Mayat)
1641
1642 * Gigasampler format engine:
1643 - extensive synthesis optimization
1644 (reimplementation of EGs and LFO(s), removed synthesis parameter
1645 prerendering and the synthesis parameter matrix in general, splitting
1646 each audio fragment into subfragments now where each subfragment uses
1647 constant pitch and filter coefficients. The volume coefficient is
1648 linearly interpolated inside a subfragment, unless
1649 --disable-interpolate-volume is set.)
1650 - fine tuning of the EG modulation parameters
1651 - improved filter cutoff calculation by adding support for the
1652 following gig parameters: Cutoff freq (used when no cutoff
1653 controller is defined), Control invert, Minimum cutoff, Velocity
1654 curve and Velocity range. The keyboard tracking now scales
1655 cutoff frequency instead of resonance.
1656 - added support for gig parameter Resonance.
1657 - fixed bug in sysex handling (patch by Juan Linietsky)
1658 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1659 which can be overridden with --enable-global-attenuation
1660 - EG fixes: made the length of "attack hold" stage more
1661 accurate. Release stage can now start before attack stage
1662 ends. Cancel release didn't work when sustain was zero. Attack
1663 time now has a minimal value to prevent clicks.
1664 - fixed pitch changes larger than one octave
1665 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1666 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1667 all modes can be altered via standard GM messages, that is CC5 for
1668 altering portamento time, CC65 for enabling / disabling portamento
1669 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1670 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1671 parameter) and crossfade
1672 - added support for the "attenuation controller threshold" gig
1673 parameter
1674 - added smoothing of volume changes caused by control change
1675 messages
1676 - sample loop parameters are now taken from the DimensionRegion
1677 instead of the wave chunk
1678 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1679 not equal to a power of two
1680 - reimplementation of the filter algorithm. The new filter is more
1681 accurate and supports all gig filter types, including bandreject
1682 and lowpass turbo.
1683 - real support for 24 bit samples - samples are not truncated to
1684 16 bits anymore
1685 - support for aftertouch (channel pressure, not polyphonic
1686 aftertouch)
1687 - LFO1 behaviour fixed (dampening from max volume instead of
1688 amplifying from 0)
1689
1690 * LSCP server:
1691 - fixed application exit on broken pipe error (fixes bug #20)
1692 - fixed the notification messages delay due to lack of
1693 network activity (fixes bug #26)
1694 - fixed parser bug which occured on space(s) within device parameters
1695 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1696
1697 * audio driver:
1698 - added aRts audio output driver (by no means RT safe)
1699
1700 * MIDI driver:
1701 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1702 messages several times instead of once
1703 - API extension for MIDI drivers which already supply exact time stamps
1704 for events (i.e. for offline rendering based MIDI drivers)
1705 - added checks for bad MIDI data
1706
1707 * linuxsampler application:
1708 - show available sampler engine types on startup
1709
1710 * general changes:
1711 - support for muting sampler channels and solo mode of the same, two new
1712 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1713 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1714 introduced for this, the behavior is the same like on a mixer console
1715 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1716 --enable-process-muted-channels which can be used to enable the
1717 processing of muted channels.
1718 - support for sostenuto pedal
1719 - support for monitoring the total number of active voices
1720 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1721 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1722 - fixed some memory management errors
1723 - fixed some concurrency problems that could lead to crashes when
1724 LSCP commands were executed
1725 - fixed crash when instrument loading failed previously on the same
1726 sampler channel (fixes bug #36)
1727
1728 Version 0.3.3 (15 July 2005)
1729
1730 * packaging changes:
1731 - fixed compilation with gcc 4.0
1732
1733 * Gigasampler format engine:
1734 - LFO preprocessing was performed even though the respective LFO was
1735 disabled by the instrument patch (minor efficiency fix)
1736 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1737 for volume ramp downs in the same fragment (needed for current voice
1738 stealing implementation) then simply inform the user with a warning
1739 about possible click sounds and reduce the volume ramp down
1740 appropriately instead of cancelling the audio device connection
1741
1742 Version 0.3.2 (24 June 2005)
1743
1744 * packaging changes:
1745 - updated autotools build files to compile on OS X
1746 (conditional compilation of CoreMIDI and MidiShare drivers)
1747 - hand-crafted assembly optimization code can be disabled with
1748 './configure --disable-asm' (definitely not recommended)
1749 - fixed 'make dist' rule to include all necessary files
1750 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1751 (due to 'dist-bzip2' automake option)
1752
1753 * Gigasampler format engine:
1754 - support for the gig parameters for "release velocity response" curves
1755 - fine tuning of the EGADSR envelope
1756 - volume of release triggered samples now depends on note-on velocity,
1757 note length and gig parameter "release trigger decay" instead of
1758 note-off velocity.
1759 - revised voice stealing
1760 (fixes crash and endless loop caused by voice stealing)
1761 - don't reset scale tuning on instrument or audio output device change
1762 - handle key group conflicts right at the beginning of each fragment
1763 instead of when the respective voice is actually launched
1764 (fixes undefined behavior if stolen voices belonged to a key group -
1765 this case was followed by a "killed voice survived" error message)
1766 - fixed minor issue with null/silence samples
1767 (those stole voices even though they don't need a voice at all which
1768 resulted in "voice stealing didn't work out" messages)
1769 - don't reset volume, pan, pitch and MIDI controller values on
1770 instrument or audio output device change
1771
1772 * LSCP server:
1773 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1774 - fixed LSCP event "CHANNEL_INFO" notification
1775 (e.g. did not notify on volume changes or MIDI program change events)
1776
1777 * linuxsampler application:
1778 - added command line parameters --lscp-addr and --lscp-port to override
1779 default IP address and port of LSCP server
1780
1781 Version 0.3.1 (24 May 2005)
1782
1783 * initial release
