File size: 100728 byte(s)
* Fixed rare crash when switching between instruments that had instrument
  scripts loaded.

* Bumped version (2.1.1.svn61).

1 Version SVN trunk (?)
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 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59 nameOfCaller() and setNameOfCaller().
60 - configure: Always check for availability of pthread_testcancel() and use
61 it if so (previously it was only used if explicitly enabled by configure
62 option).
63 - Thread class: raise compiler warning if pthread_testcancel() is not
64 available, because it can lead to deadlocks.
65 - Mutex class: Implemented optional bug detection and deadlock debugging
66 features.
67 - Ref<> class is now thread safe (as lock-free and wait-free
68 implementation).
69 - Fixed compilation error with Bison >= 3.6.0.
70 - Fixed rare crash when switching between instruments that had instrument
71 scripts loaded.
73 * Real-time instrument scripts:
74 - Added method ScriptVM::setExitResultEnabled() which allows to
75 explicitly enable the built-in exit() function to optionally accept
76 one function argument; the value of the passed exit() function
77 argument will then become available by calling
78 VMExecContext::exitResult() after script execution.
79 - 64 bit support for NKSP integer scripts variables (declare $foo).
80 - Variable names, function names and preprocessor condition names must start
81 with a regular character (a-z or A-Z); starting them with a digit or
82 underscore is not allowed.
83 - NKSP parser fix: equal comparison operator "=" and not equal comparison
84 operator "#" must only accept integer operands.
85 - NKSP language: Implemented support for standard units like Hertz, seconds,
86 Bel including support for metric unit prefixes; so one can now e.g.
87 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
88 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
89 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
90 - NKSP language: Introduced "final" operator "!" which is specifically
91 intended for synthesis parameter values to denote that the synthesis
92 parameter value is intended to be the "final" value for that synthesis
93 parameter that should explicitly be used by the engine and thus causing
94 the sampler engine to ignore all other modulation sources for the same
95 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
96 variable or formula with this new "!" operator the expression is marked as
97 being "final".
98 - NKSP script editor API: Added support for detecting standard unit tokens
99 and their potential metric prefix token.
100 - NKSP language: Added support for NKSP real number literals and
101 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
102 - NKSP language: Added support for NKSP real number (floating point) script
103 variables (declare ~foo).
104 - NKSP language: Added support for NKSP real number (floating point) array
105 script variables (declare ?foo[]).
106 - Built-in script function "message()" accepts now real number argument as
107 well.
108 - Added built-in script function "real_to_int()" and its short hand form
109 "int()" for casting from real number to integer in NKSP scripts.
110 - Added built-in script function "int_to_real()" and its short hand form
111 "real()" for casting from integer to real number in NKSP scripts.
112 - Allow built-in exit() function to potentially accept real number type
113 argument as well.
114 - Built-in script functions may have a different return type depending on
115 the arguments passed to the function.
116 - Built-in script function "abs()" optionally accepts and returns real
117 number.
118 - Built-in script functions "min()" and "max()" optionally accept real
119 number arguments and return real number as result in that case.
120 - NKSP VM API: Allow units and 'final'ness to be returned as result from
121 built-in functions (added methods VMFunction::returnUnitType() and
122 VMFunction::returnsFinal() for that purpose which must be implemented by
123 built-in function implementations).
124 - NKSP language: Allow metric unit prefixes of numeric scalar and array
125 variables to be changed freely at runtime (unlike unit types like Hz etc.
126 which are still sticky, parse-time features of variables which cannot be
127 changed at runtime for the intentional sake of determinism).
128 - NKSP language: 'final' values are prohibited for array variables for now
129 (attempt causes a parsers error).
130 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
131 conditions of runtime control structures like if(), while(), select()
132 (attempt causes a parser error).
133 - NKSP VM API: Allow built-in functions to perform their own, individual
134 parse time checks of arguments going to be passed to the function at
135 runtime (added method VMFunction::checkArgs() for that purpose).
136 - NKSP language: raise parser warning if only one operand of binary
137 operators (like logical 'or' comparison) contain a 'final' value (because
138 it would always yield in a 'final' result in such cases).
139 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
140 different metric unit prefixes, which will behave as expected (e.g.
141 result of expression '1000us < 2ms' is true).
142 - NKSP language: Allow adding values with different metric unit prefixes
143 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
144 - NKSP language: Allow subtracting values with different metric unit
145 prefixes (e.g. result of expression '1ms - 20us' is '980us').
146 - NKSP language: Allow multiplying with any metric unit prefixes
147 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
148 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
149 we don't have any considerable practical use for a term like '4s^2'
150 (hence any attempt multiplying two unit types still causes parser error).
151 - NKSP language: Allow dividing by any metric unit prefixes and allow
152 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
153 yields in unit free result '8'). So this is now a way to cast units away
154 e.g. for passing the result to other expressions, certain function calls
155 or variables which are not accepting any units (or that specific unit).
156 - NKSP language: integer arrays and real number arrays can now be converted
157 to strings (e.g. for dumping their content with message() calls for
158 script debugging purposes).
159 - NKSP language: expressions and variables with units are now correctly
160 casted to strings (e.g. with message() calls).
161 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
162 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
163 floating point tolerances into account.
164 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
165 VMScalarNumberExpr::evalCastReal().
166 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
167 'VMIntArrayExpr' and 'VMRealArrayExpr'.
168 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
169 unitFactor() (runtime) methods.
170 - Built-in function "exit()" supports now returning units and 'final'ness
171 for test cases.
172 - The following built-in functions support now units as well: "abs()",
173 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
174 "real_to_int()", "int()", "int_to_real()" and "real()".
175 - Built-in functions "array_equal()", "search()" and "sort()" support now
176 real number arrays (correctly) as well.
177 - Added individual parse time checks of arguments to be passed to built-in
178 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
179 "array_equal()" and "search()" specific for their individual purposes.
180 - NKSP VM refactoring: Renamed all methods, functions and classes matching
181 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
182 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
183 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
184 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
185 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
186 isScalarNumber() -> isNumber()).
187 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
188 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
189 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
190 as convenient methods for automatically converting values to expected
191 metric value basis.
192 - Built-in function "wait()" accepts now both integers and real numbers as
193 argument.
194 - NKSP VM API cleanup: Get rid of legacy method
195 VMFunction::argType(vmint iArg) which was already superseded by its new
196 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
197 - NKSP parser: if wrong argument type was passed to a built-in function and
198 that built-in function accepts more than one data type for the argument,
199 then show all supported data types as parser error message.
200 - Built-in function "play_note()" accepts now real numbers and seconds as
201 unit type as well for its 3rd and 4th function arguments.
202 - The following built-in functions accept now real numbers as well for their
203 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
204 "change_attack()", "change_decay()", "change_release()",
205 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
206 "change_cutoff_sustain()", "change_cutoff_release()",
207 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
208 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
209 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
210 - Fixed built-in function "change_play_pos()" not having accepted metric
211 prefixes at all.
212 - Fixed the following built-in functions having misinterpreted values given
213 with unit type (for their 2nd argument) as if they were relative values
214 (that is as if they were passed without a unit type): "change_attack()",
215 "change_decay()", "change_release()", "change_cutoff_attack()",
216 "change_cutoff_decay()", "change_cutoff_release()".
217 - Fixed the following built-in functions having applied completely wrong
218 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
219 respective EGs being their modulation sink assume uint data type with
220 value range 0..1000 instead of 0.0..1.0.
221 - Added individual parse-time checks of function arguments for the following
222 built-in functions: "play_note()", "note_off()", "set_event_mark()",
223 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
224 "change_decay()", "change_release()", "change_cutoff_attack()",
225 "change_cutoff_decay()", "change_cutoff_release()",
226 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
227 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
228 "change_pan_time()".
229 - Don't abort function call if unit type was used and at the same time
230 'final' operator was omitted for the primary value argument of the
231 following built-in functions: "change_cutoff()", "change_attack()",
232 "change_decay()", "change_release()", "change_cutoff_attack()",
233 "change_cutoff_decay()", "change_cutoff_release()",
234 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
235 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
236 "change_pan_time()", instead imply 'final'ness at runtime and raise an
237 appropriate parser warning at parse time.
238 - Added built-in real number functions "round()", "ceil()", "floor()",
239 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
240 "cos()", "tan()", "asin()", "acos()", "atan()".
241 - Added built-in script real number constant "~NI_MATH_PI".
242 - Added built-in script real number constant "~NI_MATH_E".
243 - NKSP language: Allow unary '+' operator.
244 - Added built-in script functions "msb()" and "lsb()".
245 - NKSP language: Added support for RPN event handler
246 ("on rpn ... end on" in instrument scripts).
247 - NKSP language: Added support for NRPN event handler
248 ("on nrpn ... end on" in instrument scripts).
249 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
250 may be read from the new RPN/NRPN script handlers to get the (N)RPN
251 parameter that had been changed and its new value.
252 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
253 which are identifying the new (N)RPN handlers as such at script runtime.
254 - Implemented built-in script function "set_rpn()".
255 - Implemented built-in script function "set_nrpn()".
256 - Fix: built-in functions returning an array type were broken and caused a
257 crash when the built-in function's (supposed to be array) result value was
258 used by the script VM.
259 - Removed upper value constraint for 2nd argument of built-in functions
260 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
261 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
262 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
263 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
264 the LFO frequency / resonance / cutoff frequency.
265 - Reduced code involved for parsing NKSP variable declarations by using 2
266 generalized grammar rules with optional components (i.e. optional value
267 assignment and optional variable qualifiers) instead of previous linear
268 combinations of grammar rules, which also fixes some edge case.
269 - NKSP language parser: track code block locations also by a) raw byte
270 position in NKSP source code string and b) length of that code block in
271 bytes (along to the already existing code block tracking by line/column);
272 and added appropriate new members to public C++ API classes like
273 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
274 - NKSP language: Added support for 'patch' variable qualifier (capture their
275 locations and allow replacement of their assignment expression via VM C++
276 API).
277 - Fixed incorrect EG times if standard measuring unit was passed to built-in
278 functions "change_attack()", "change_decay()" or "change_release()".
279 - Fixed intermediate function result values never having reflected any
280 standard measuring unit type.
281 - Fixed re-entrant issue with function calls which caused wrong result
282 values if the same function was called multiple times in a term
283 (specifically if metric prefixes were used).
284 - NKSP language: Just throw a warning, not an error if an array variable of
285 size zero was declared.
286 - NKSP language: Allow omitting explicit array size on array variable
287 declaration if combined with immediate value assignment
288 (e.g. declare %foo[] := ( 1, 2, 3 ) ).
289 - NKSP language: emit warning if an array variable was declared with bigger
290 array size than amount of initial values been assigned, and initialize the
291 missing array elements with zero in this case.
293 * test cases:
294 - Fixed compiler errors in test cases.
295 - Updated README for how to compile & run test cases.
296 - Updated test case
297 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
298 expected behaviour of the Mutex class implementation (recursive
299 mutex type).
300 - Added test cases for NKSP core language aspects and core built-in
301 functions.
302 - Fixed thread tests segfaulting on Linux.
303 - NKSP: Added real number test cases for built-in functions exit(),
304 int_to_real(), real(), real_to_int() and int(), as well as for the
305 plus, minus and negate language operators.
306 - Added massive amount of NKSP test cases for standard measuring units and
307 'final' operator usage cases.
308 - Added NKSP test cases for (floating point tolerance aware) real number
309 equalness / unequalness comparison.
310 - Added NKSP int array and real array tests for value assignment and
311 initialization of arrays.
312 - Added NKSP test cases for built-in functions "round()", "ceil()",
313 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
314 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
315 - Added NKSP test cases for unary '+' operator.
316 - Added NKSP test cases for core built-in variables.
317 - Added thorough NKSP test cases for variable declarations.
319 * GigaStudio/Gigasampler format engine:
320 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
321 behaviour for start_level_mid.
322 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
323 level (see discussion "GigaStudio LFO compatibility" on mailing list
324 from 2019-09-26 for details).
325 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
326 see discussion "GigaStudio LFO compatibility" on mailing list from
327 2019-09-26 for details).
328 - Format extension: Added support for different LFO wave forms (currently
329 either sine [default], triangle, saw or square).
330 - Format extension: Added support for LFO phase displacement (0��..360��).
331 - Format extension: Added support for flipping LFO polarity on LFO 3
332 (in the original gig format this was only available for LFO 1 and LFO 2).
333 - Format extension: Support for additional filter types:
334 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
335 bandreject 2-pole.
336 - Fixd potential crash with polynomial interpolator and max. pitch.
337 - If minimum cutoff is defined, remap cutoff controller CC values to really
338 span the entire possible cutoff range (and avoiding a dead controller
339 zone).
340 - Implemented support for loading instrument scripts with 'patch' variables
341 (by patching these script variables with potentially overridden ones by
342 gig Instrument).
344 * SFZ format engine:
345 - Fixed support for regions with loccN/hiccN conditions on more than one
346 MIDI controller.
348 * Benchmarks:
349 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
350 algorithm (since result of 2nd run was not accumulated).
351 - Added benchmark for saw wave (benchmarks/saw.cpp).
352 - Added benchmark for sine wave (benchmarks/sine.cpp).
353 - Added benchmark for square wave (benchmarks/square.cpp).
354 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
355 which are large enough on modern systems.
357 Version 2.1.1 (27 Jul 2019)
359 * Real-time instrument scripts:
360 - Fixed behavior of built-in NKSP functions change_sustain(),
361 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
362 and change_cutoff_release().
364 * general changes:
365 - Only play release trigger samples on sustain pedal up if this behaviour
366 was explicitly requested by the instrument (otherwise only on note-off).
367 - Fixed compiler warnings.
368 - Fixed compilation error when cross-compiling to Mac.
369 - FX Sends: Provide more useful error messages on routing problems
370 (see bug #169).
371 - LSCP doc: Be more clear describing the two distinct approaches
372 of using external vs. internal effects (see bug #169).
373 - "optional" class: Fixed comparison operators.
375 * Gigasampler/GigaStudio format engine:
376 - Format extension: If requested by instrument then don't play release
377 trigger sample on note-off events.
379 * SFZ format engine:
380 - Fixed memory leak when releasing samples
381 (fixes bug #307, patch by Jacek Roszkowski)
382 - Fixed potential crash when a sample is shared by more than one region
383 (fixes bug #308, patch by Jacek Roszkowski).
384 - Opcode 'sample': Added support for built-in sample '*silence'
385 (fixes bug #310, patch by Jacek Roszkowski).
387 Version 2.1.0 (25 Nov 2017)
389 * SFZ format engine:
390 - added support for <global>, <master> and #define (patch by Alby M)
391 - Removed code duplication in SFZ file loading code.
392 - Added support for sfz extension opcode 'script' which may be used to
393 load real-time instrument script file (NKSP script language).
394 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
395 - Fixed unintended volume fade-in of voices under certain conditions.
396 - sfz parser: allow missing space between header and opcode
398 * Gigasampler/GigaStudio format engine:
399 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
400 cutoff settings.
401 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
402 all if an up-pitch of more than 40 semi tones was requested (I don't
403 think there is any stock gig sound that requires this behavior to
404 resemble its original sound).
405 - Added support for controlling whether the individual EGADSR stages may
406 be aborted (as LinuxSampler extension to the original GigaStudio 4
407 format).
409 * general changes:
410 - fixed printf type errors (mostly in debug messages)
411 - use unique_ptr instead of auto_ptr when building with C++11
412 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
413 allowing to sort data efficiently in real-time safe manner.
414 - RTList class: added methods for moving/inserting elements to arbitrary
415 position within a list.
416 - RTList class: added method fromPtr() for creating an Iterator object from
417 a raw element pointer.
418 - Attempt to partly fix resetting engine channels vs. resetting engine, an
419 overall cleanup of the Reset*(), ConnectAudioDevice(),
420 DisconnectAudioDevice() API methods would still be desirable though,
421 because the current situation is still inconsistent and error prone.
422 - Active voices are now internally grouped to "Note" objects, instead of
423 being directly assigned to a keyboard key. This allows more fine graded
424 processing of voices, which is i.e. required for certain instrument
425 script features.
426 - Fix: Release trigger voices were not spawned on sustain pedal up
427 (CC #64) events.
428 - Fix: Release trigger voices can now also distinguish correctly between
429 note-off and sustain pedal up events.
430 - All engines: Increased ramp speed of volume smoother and pan smoother
431 (while slow rate of crossfade smoother is preserved) to allow quick
432 volume and pan changes by instrument scripts for instance.
433 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
434 properly and thus were ignored for certain uses.
435 - Added new C++ API method
436 VirtualMidiDevice::SendChannelPressureToSampler().
437 - windows, 32-bit: fixed potential crashes by making sure the stack in
438 sub threads is 16-byte aligned
439 - fixed numerous compiler warnings
440 - Fixed invalid (note-on) event ID being assigned to new Note objects.
441 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
442 fixes potential undefined behavior.
443 - Fixed Note object leak when triggering notes on keys which did not
444 have a valid sample mapped (fixes bug #252).
445 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
446 - linuxsampler binary fix: option --create-instruments-db ignored
447 subsequent optional argument due to glibc's implementation oddity
448 which expects a "=" sign, but no space between them.
450 * packaging changes:
451 - removed unnecessary dependency to libuuid
452 (originated by libgig's usage of it)
453 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
454 auto detect whether it (sh/c)ould output its messages in color.
455 - Debian: Fixed packaging error about invalid "Source-Version"
456 substitution variable.
457 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".

459 linuxsampler with instruments DB support.
461 * Real-time instrument scripts:
462 - Implemented scheduler for delayed MIDI events and for suspended scripts.
463 - Built-in script function "wait()": implemented support for function's
464 "duration-us" argument, thus scripts using this function are now
465 correctly resumed after the requested amount of microseconds.
466 - Built-in script function "play_note()": implemented support for
467 function's "duration-us" argument, thus notes triggered with this
468 argument are now correctly released after the requested amount of
469 microseconds.
470 - Fix: script events were not cleared when engine channel was reset,
471 potentially causing undefined behavior.
472 - Fixed crash which happened when trying to reference an undeclared
473 variable.
474 - Built-in script function "play_note()": Added support for passing
475 special value -1 for "duration-us" argument, which will cause the
476 triggered note to be released once the original note was released.
477 - Instrument script classes now exported with the liblinuxsampler C++ API.
478 - Added new API method ScriptVM::syntaxHighlighting() which provides
479 a convenient syntax highlighting backend for external instrument
480 script editor applications.
481 - Added new C++ API class "ScriptVMFactory".
482 - Extended parser issues to provide not only first line and first
483 column, but also last line and last column of issue (thus marking
484 the precise span of the issue within the source code).
485 - Reload script automatically after being modified by an instrument
486 editor.
487 - NKSP language grammar correction: allow empty event handler bodies
488 like "on note end on".

494 - Implemented built-in script function "event_status()".
495 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
496 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
497 "event_status()" function.
498 - NKSP language: Added support for bitwise operators ".or.", ".and."
499 and ".not.".
500 - NKSP language scanner: Fixed IDs matching to require at least one
501 character (i.e. when matching function names or variable names).
502 - NKSP language scanner: disabled unusued rules.
503 - Fixed behavior of play_note() and note_off() functions which must
504 be distinguished engine internally from "real" MIDI note on/off
505 events in order to avoid misbehaviors like hanging notes.
506 - Implemented built-in script variable "$KSP_TIMER".
507 - Implemented built-in script variable "$NKSP_REAL_TIMER".
508 - Implemented built-in script variable "$NKSP_PERF_TIMER".

512 - NKSP language fix: division expressions were evaluated too often.
513 - NKSP language fix: string concatenation operator was right
514 associative instead of left (to right).
515 - NKSP language correction: allow empty statements in entire language
516 (i.e. "if end if").
517 - Implemented built-in script function "stop_wait()".

529 - Implemented built-in script function "change_decay()".
530 - Implemented built-in script function "change_release()".
531 - Fixed all change_*() built-in script functions to apply their
532 synthesis parameter changes immediately in case the respective note
533 was triggered at the same time, instead of scheduling the parameter
534 change, especially because it would cause some parameter types's
535 changes either to be ramped (i.e. change_vol()) or other types even
536 to have not effect at all (i.e. change_attack()).
537 - Implemented built-in script function "sh_left()".
538 - Implemented built-in script function "sh_right()".
539 - Implemented built-in script function "min()".
540 - Implemented built-in script function "max()".
541 - NKSP Fix: "init" event handler was not always executed when a script
542 was loaded.
543 - NKSP built-in wait() script function: abort script execution if
544 a negative or zero wait time was passed as argument (since this is
545 a common indication of a bug either of the script or even of the
546 engine, which could lead to RT instability or even worse).
547 - ScriptVM: Implemented automatic suspension of RT safety
548 threatening scripts.
549 - Provide more user friendly error messages on syntax errors.
550 - Fixed NKSP parser warning "Not a statement" when assigning an
551 initializer list to an array variable.

558 - Implemented built-in script function "change_vol_time()".
559 - Implemented built-in script function "change_tune_time()".
560 - Implemented built-in script function "fade_in()".
561 - Implemented built-in script function "fade_out()".
562 - Fixed acceptance of wrong data type of parameters passed to built-in
563 script functions "change_vol()", "change_tune()", "change_pan()",
564 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
565 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
566 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
567 - Added built-in script function "get_event_par()" and implemented some
568 of its possible parameter selections.
569 - Added built-in script function "set_event_par()" and implemented some
570 of its possible parameter selections.
571 - Fixed a bunch of scheduler time related bugs.
572 - Fixed polyphonic variables not being reset to zero after usage.
573 - Built-in "ignore_event()" function: argument is now optional, like with
574 built-in function "ignore_controller()".
575 - Implemented built-in script function "change_velo()".
576 - Implemented built-in script function "change_note()".
577 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
578 intuitive behavior if used in combination with "change_vol_time()" or
579 "change_tune_time()" respectively: now tuning/volume changes are only
580 assigned (without delay) immediately to a new note if the respective
581 timing function has not been called before, otherwise the volume/tuning
582 changes are automatically faded (before, only the event's time stamp was
583 relevant).
584 - Implemented built-in script function "array_equal()".
585 - Implemented built-in script function "search()".
586 - Implemented built-in script function "sort()".
587 - NKSP Fix: Never suspend "init" event handlers.
588 - Implemented built-in script function "same_region()" (currently only
589 available for gig format engine).
590 - Added built-in script constant "$NKSP_LINEAR".
591 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
592 - Implemented built-in script function "change_vol_curve()".
593 - Implemented built-in script function "change_tune_curve()".
594 - built-in "play_note()" function now supports a sample playback start
595 offset with argument 3, where special value -1 means to use the regular
596 sample offset as defined by the instrument file.
597 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
598 - Built-in variable $EVENT_NOTE is now a read-only variable.
599 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
600 - built-in "play_note()" function now accepts -2 for its fourth argument
601 (note duration) which means the life time of the note shall be sticked
602 to the requested note number of argument 1.
603 - Fix: built-in "play_note()" function now returns 0 as result value if
604 -1 was passed for its fourth argument (note duration) and the respective
605 parent note is already gone.
606 - Implemented built-in script function "change_play_pos()".
607 - NKSP language: Added support for user declared const array variables.
608 - NKSP language: Raise parser warning if array variable is accessed with
609 an index that exceeds the array's size.
610 - NKSP language fix: Unknown characters were not handled correctly.
611 - NKSP language: Added support for "synchronized .. end synchronized"
612 code blocks.
613 - Implemented built-in script function "abort()" which allows to abort
614 another script handler by passing its callback ID.
615 - Fixed potential memory access bug and potential undefined behavior of
616 "init" event handlers.
617 - Print a time stamp along to each call of built-in function "message()".
618 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
619 to retrieve all code blocks filtered out by the preprocessor.
620 - Added built-in script function "fork()".
621 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
622 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

626 - Added built-in constant $CALLBACK_STATUS_QUEUE.
627 - Added built-in constant $CALLBACK_STATUS_RUNNING.
628 - Removed max. value limitation of built-in functions "change_attack()",
629 "change_decay()" and "change_release()" to i.e. allow passing 2000000
630 for doubling the respective time.
631 - NKSP script editor syntax highlighting API: Fixed app termination due
632 to a lexer start condition stack underrun.
633 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
634 USE_CODE_IF_NOT() preprocessor statements.
635 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
636 can be set to disable all subsequent built-in "message()" function calls
637 on preprocessor level.
638 - Implemented built-in script function "change_sustain()".
639 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

652 undefined behavior.
653 - Cleanup of instruments DB file creation and opening code.

655 is now optional, if it is missing, then a default location is used.
656 - Added support for scanning SFZ (.sfz) files.
657 - Added support for scanning Sound Font (.sf2) files.
658 - Fixed undefined DB transaction behavior.

672 - minor Makefile fix for building lscpparser when build and source
673 directories are separate
674 - Mac OS X: made it possible to specify plugin installation dir to
675 configure
676 - Mac OS X: Makefile fix for the install-strip target
677 - fixed compilation with gcc 4.7
678 - fixed configure script error with old autoconf versions
679 - lsatomic.h: use gcc provided atomic functions if building with
680 gcc 4.7 and C++11
681 - modernized configure script
682 - fixed linkage error when building with
683 LDFLAGS="-Wl,--no-undefined" (#190)
684 - fixed compilation with Clang 3.2
685 - removed usage of deprecated Automake variable INCLUDES

688 - build fix: libsndfile compiler flags were missing in some
689 makefiles
690 - fix for building with bison 3.0 (#202)

692 on the process's main thread
693 - fixed build error on newer MinGW
694 - support building with older jack versions
695 - support building with spaces in vst sdk path
696 - enabled automake 'subdir-objects' option and moved external
697 source references (vst, au, asio) from makefiles to cpp files,
698 in order to get rid of warnings from automake 1.14
700 * general changes:
701 - Refactoring: moved the independent code from
702 the Gigasampler format engine to base classes
703 - command line option '--profile' is currently disabled, since the
704 respective profiling code is currently broken
705 - Introduced support for optional environment variable
706 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
707 where the sampler shall look for instrument editor plugins
708 (patch by Luis Garrido, slightly modified).
709 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
710 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
711 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
712 note (in this implementation of the sampler its simply hard routed to
713 the 1st effect send of the sampler channel, no matter what the actual
714 effect type is)
715 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
716 note (in this implementation of the sampler its simply hard routed to
717 the 2nd effect send of the sampler channel, no matter what the actual
718 effect type is)
719 - implemented support for internal LADSPA effects
720 - raised limit of program change queue from 100 to 512
721 (as suggested by Alex Stone)
722 - implemented sine LFO, pulse LFO and saw LFO
723 - experimental support for per voice equalization
724 - added command line option --exec-after-init
725 - Introduced new C++ API method:
726 EngineChannel::InstrumentFileName(int index)
727 allowing to retrieve the whole list of files used for the loaded
728 instrument on an engine channel (a.k.a. part). Some GigaStudio
729 instruments for example are splitted over several files like
730 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
731 - Added new C++ API method Sampler::GetGlobalMaxVoices().
732 - Added new C++ API method Sampler::GetGlobalMaxStreams().
733 - Added new C++ API method Sampler::SetGlobalMaxVoices().
734 - Added new C++ API method Sampler::SetGlobalMaxStreams().
735 - Various "const" and "restrict" optimizations.
736 - all engines: add pan CC value to instrument pan parameter before
737 applying panning, instead of using two separate pan functions in
738 series (#182)
739 - added a lock guard class for exception safe mutex handling and
740 used it everywhere appropriate
741 - Immediately apply scale tuning changes to active voices.
742 - Exposed scale tuning to C++ API (along to the already existing standard
743 SysEx way).
744 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
745 and broken for ppc64. (Seq_cst loads and stores are actually not
746 used in LS, so the bug wasn't noticable.)
747 - lsatomic.h: added ARMv7 support
748 - Added support for multiple MIDI input ports per sampler channel (and
749 added various new C++ methods for this new feature / design change, old
750 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
751 as deprecated but are still there and should provide full behavior
752 backward compatibility).
753 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
754 unsafe and caused compilation error with clang 2.x).
755 - Bugfix: only process the latest MIDI program change event.
756 - Introducing the LSCP shell, which provides convenient control of the
757 sampler from the command line by providing LSCP aware features.
758 - VirtualMidiDevice: Added support for program change.
759 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
760 - VirtualMidiDevice: Added support for pitch bend.
761 - Aftertouch: extended API to explicitly handle channel pressure and
762 polyphonic key pressure events (so far polyphonic pressure was not
763 supported at all, and channel pressure was rerouted as CC128 but not
764 used so far).
765 - Added initial support for real-time instrument scripts. The script VM
766 code is shared by all sampler engine implemementations, however only the
767 gig file format currently provides support for storing instrument scripts
768 (as LinuxSampler extension to the original GigaStudio 4 format).
770 * Gigasampler format engine:
771 - implemented the "round robin keyboard" dimension
772 - fixed round robin and random dimensions for cases when number of
773 dimension zones is not a power of two
774 - made round robin use a counter for each region instead of each
775 key
776 - bugfix: pitch LFO controller "internal+aftertouch" was broken
777 - bugfix: filter keyboard tracking was broken
778 - filter performance fix (an unnecessary copy was made of the
779 filter parameters in each sub fragment)
780 - handle special case when pan parameter in gig file has max or
781 min value
782 - Exclusive Groups: don't ever stop voices of the same note,
783 doesn't sound naturally with a drumkit
784 - fixed EG1 modulation when attack or release is zero
785 - Fixed support for 'aftertouch' attenuation controller.
786 - Fixed crash that happened with velocity split sounds under certain
787 conditions (see also previous commit on libgig).
788 - fixed behaviour of filter LFO
790 * SFZ format engine:
791 - Initial implementation (not usable yet)
792 - added support for v2 multiple stage envelope generators
793 - added a fine-tuned v1 envelope generator instead of using the
794 one from the gig engine
795 - fixed memory leak and memory handling errors
796 - added support for trigger=first, trigger=legato and sw_previous
797 - allow non-numerical key values ("C#4" for example)

799 - fixed error when unloading instrument with same sample used by
800 multiple regions
801 - added some opcode aliases, like loopmode for loop_mode, to be
802 more compatible
803 - added support for trigger=release and rt_decay
804 - added support for off_mode=normal
805 - added support for random, seq_position, seq_length and volume
806 - added v1 LFO opcodes to parser (no support in engine yet)
807 - added support for amp_veltrack and amp_velcurve_N
808 - fine-tuned the default velocity curve
809 - added support for transpose
810 - fixed crash when using sw_down/up
811 - improved logic for sw_lokey/hikey/up/down/last
812 - added more v1 aliases to parser
813 - reduced memory usage for sfz data
814 - RT-safeness: avoid malloc in audio thread
815 - fixed a bug that could cause voice stealing to fail
816 - optimized sample lookup
817 - improved support for exclusive groups (group, off_by and
818 off_mode)
819 - added support for controller triggered regions (on_locc/on_hicc)
820 - added support for loop_mode=one_shot
821 - fixed playback of 16 bit wav files on big endian CPUs
822 - added support for Ogg Vorbis sample files
823 - use loop markers from sample file if loop_start and loop_end are
824 not set in sfz file
825 - implemeted filters. Filter types: lowpass, bandpass, bandreject
826 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
827 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
828 cutoff_cc, cutoff_chanaft.
829 - bugfix: zero ampeg_sustain didn't work
830 - added support for velocity effect on amplifier envelope time
831 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
832 ampeg_vel2release)
833 - added support for EG hold (ampeg_hold)

1018 the driver will automatically connect to other CoreMIDI clients' ports
1019 (e.g. external MIDI devices being attached to the Mac)
1020 - added support for MIDI note on velocity filter
1021 - CoreMIDI: fixed memory deallocation error
1022 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1193 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1194 (fixes #208)
1195 - Fixed bug in LSCP grammar definition which caused a statement like
1196 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1197 practically irrelevant, however it caused problems with the new LSCP
1198 shell's auto completion feature).
1199 - Fixed MIDI program change messages being ignored if quickly executed
1200 after each other (fixes #231).
1202 Version 1.0.0 (31 July 2009)
1204 * packaging changes:

1217 directory of liblinuxsampler dll (look in the same directory and one
1218 directory above)
1219 - configure script fix: removed unconditional use of SSE
1220 - fixed building with sqlite installed in a non-standard directory
1221 - when cross-compiling, don't try to create instruments.db

1224 * general changes:
1225 - bugfix: on some POSIX systems instrument editor plugins refused to

1227 (fixes bug #70, patch by Ronald Baljeu)
1228 - fixed endless loop which occured when loading an instrument editor
1229 plugin DLL on Windows systems failed
1230 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1231 - optimized the SynchronizedConfig class so it doesn't wait
1232 unnecessarily long after an update

1234 events (e.g. to highlight the pressed keys on the virtual keyboard
1235 of gigedit)
1236 - added support for triggering notes by instrument editors (see above)
1237 - be verbose on DLL load errors (on Linux)
1238 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1239 is only used by very few systems, most pick the int math
1240 implementation, which is usually faster)
1241 - fixes for audio drivers with varying buffer sizes
1242 - experimental support for running LinuxSampler as a DSSI, LV2 and
1243 VST plugin
1244 - notification events for stream/voice count statistics are now sent

1247 multi-core and multi-cpu systems
1248 - maximum voices and disk streams can now be altered at runtime
1249 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1250 - automatic stacktrace mechanism is now turned off by default and can
1251 be switched on by command line option "--stacktrace" (the automatic
1252 stacktrace mechanism seems to be broken on most systems at the moment)
1253 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1254 a pointer to the launched InstrumentEditor object
1255 - added optional 3rd party user data parameter for following
1256 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1257 InstrumentEditor::Launch(),
1258 InstrumentManager::LaunchInstrumentEditor()
1259 - theoretical fix: made SynchronizedConfig follow C++0x memory
1260 model more strictly
1261 - fixes for using large audio device buffers
1262 - Windows: add the installation directory to the DLL search path
1263 when loading an editor plugin (solves problems with VST and
1264 gigedit on systems with other GTK versions installed)

1267 * audio driver:
1268 - removed the nonsense audio channel constraint (which was hard coded to
1269 max. 100 audio channels) for most audio drivers
1270 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1271 opposed to the LSCP specs
1272 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1273 reflected the wrong value
1274 - fixed a memory management bug in ASIO driver
1275 - Makefile fix: JACK_CFLAGS wasn't used
1276 - JACK: use jack_client_open instead of the deprecated

1283 win64)
1284 - VST: added support for sample rate and buffer size changes
1285 - VST: close editor (Fantasia) when the VST is removed
1286 - VST: avoid opening Fantasia more than once for each VST instance

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