* Allow EffectChain::InsertEffect() as alternative to
  EffectChain::AppendEffect() (i.e. with index equal to current chain size).

* Bumped version (2.1.1.svn67).

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.
72 - Allow EffectChain::InsertEffect() as alternative to
73 EffectChain::AppendEffect() (i.e. with index equal to current chain size).
75 * Real-time instrument scripts:
76 - Added method ScriptVM::setExitResultEnabled() which allows to
77 explicitly enable the built-in exit() function to optionally accept
78 one function argument; the value of the passed exit() function
79 argument will then become available by calling
80 VMExecContext::exitResult() after script execution.
81 - 64 bit support for NKSP integer scripts variables (declare $foo).
82 - Variable names, function names and preprocessor condition names must start
83 with a regular character (a-z or A-Z); starting them with a digit or
84 underscore is not allowed.
85 - NKSP parser fix: equal comparison operator "=" and not equal comparison
86 operator "#" must only accept integer operands.
87 - NKSP language: Implemented support for standard units like Hertz, seconds,
88 Bel including support for metric unit prefixes; so one can now e.g.
89 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
90 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
91 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
92 - NKSP language: Introduced "final" operator "!" which is specifically
93 intended for synthesis parameter values to denote that the synthesis
94 parameter value is intended to be the "final" value for that synthesis
95 parameter that should explicitly be used by the engine and thus causing
96 the sampler engine to ignore all other modulation sources for the same
97 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
98 variable or formula with this new "!" operator the expression is marked as
99 being "final".
100 - NKSP script editor API: Added support for detecting standard unit tokens
101 and their potential metric prefix token.
102 - NKSP language: Added support for NKSP real number literals and
103 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
104 - NKSP language: Added support for NKSP real number (floating point) script
105 variables (declare ~foo).
106 - NKSP language: Added support for NKSP real number (floating point) array
107 script variables (declare ?foo[]).
108 - Built-in script function "message()" accepts now real number argument as
109 well.
110 - Added built-in script function "real_to_int()" and its short hand form
111 "int()" for casting from real number to integer in NKSP scripts.
112 - Added built-in script function "int_to_real()" and its short hand form
113 "real()" for casting from integer to real number in NKSP scripts.
114 - Allow built-in exit() function to potentially accept real number type
115 argument as well.
116 - Built-in script functions may have a different return type depending on
117 the arguments passed to the function.
118 - Built-in script function "abs()" optionally accepts and returns real
119 number.
120 - Built-in script functions "min()" and "max()" optionally accept real
121 number arguments and return real number as result in that case.
122 - NKSP VM API: Allow units and 'final'ness to be returned as result from
123 built-in functions (added methods VMFunction::returnUnitType() and
124 VMFunction::returnsFinal() for that purpose which must be implemented by
125 built-in function implementations).
126 - NKSP language: Allow metric unit prefixes of numeric scalar and array
127 variables to be changed freely at runtime (unlike unit types like Hz etc.
128 which are still sticky, parse-time features of variables which cannot be
129 changed at runtime for the intentional sake of determinism).
130 - NKSP language: 'final' values are prohibited for array variables for now
131 (attempt causes a parsers error).
132 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
133 conditions of runtime control structures like if(), while(), select()
134 (attempt causes a parser error).
135 - NKSP VM API: Allow built-in functions to perform their own, individual
136 parse time checks of arguments going to be passed to the function at
137 runtime (added method VMFunction::checkArgs() for that purpose).
138 - NKSP language: raise parser warning if only one operand of binary
139 operators (like logical 'or' comparison) contain a 'final' value (because
140 it would always yield in a 'final' result in such cases).
141 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
142 different metric unit prefixes, which will behave as expected (e.g.
143 result of expression '1000us < 2ms' is true).
144 - NKSP language: Allow adding values with different metric unit prefixes
145 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
146 - NKSP language: Allow subtracting values with different metric unit
147 prefixes (e.g. result of expression '1ms - 20us' is '980us').
148 - NKSP language: Allow multiplying with any metric unit prefixes
149 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
150 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
151 we don't have any considerable practical use for a term like '4s^2'
152 (hence any attempt multiplying two unit types still causes parser error).
153 - NKSP language: Allow dividing by any metric unit prefixes and allow
154 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
155 yields in unit free result '8'). So this is now a way to cast units away
156 e.g. for passing the result to other expressions, certain function calls
157 or variables which are not accepting any units (or that specific unit).
158 - NKSP language: integer arrays and real number arrays can now be converted
159 to strings (e.g. for dumping their content with message() calls for
160 script debugging purposes).
161 - NKSP language: expressions and variables with units are now correctly
162 casted to strings (e.g. with message() calls).
163 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
164 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
165 floating point tolerances into account.
166 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
167 VMScalarNumberExpr::evalCastReal().
168 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
169 'VMIntArrayExpr' and 'VMRealArrayExpr'.
170 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
171 unitFactor() (runtime) methods.
172 - Built-in function "exit()" supports now returning units and 'final'ness
173 for test cases.
174 - The following built-in functions support now units as well: "abs()",
175 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
176 "real_to_int()", "int()", "int_to_real()" and "real()".
177 - Built-in functions "array_equal()", "search()" and "sort()" support now
178 real number arrays (correctly) as well.
179 - Added individual parse time checks of arguments to be passed to built-in
180 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
181 "array_equal()" and "search()" specific for their individual purposes.
182 - NKSP VM refactoring: Renamed all methods, functions and classes matching
183 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
184 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
185 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
186 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
187 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
188 isScalarNumber() -> isNumber()).
189 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
190 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
191 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
192 as convenient methods for automatically converting values to expected
193 metric value basis.
194 - Built-in function "wait()" accepts now both integers and real numbers as
195 argument.
196 - NKSP VM API cleanup: Get rid of legacy method
197 VMFunction::argType(vmint iArg) which was already superseded by its new
198 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
199 - NKSP parser: if wrong argument type was passed to a built-in function and
200 that built-in function accepts more than one data type for the argument,
201 then show all supported data types as parser error message.
202 - Built-in function "play_note()" accepts now real numbers and seconds as
203 unit type as well for its 3rd and 4th function arguments.
204 - The following built-in functions accept now real numbers as well for their
205 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
206 "change_attack()", "change_decay()", "change_release()",
207 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
208 "change_cutoff_sustain()", "change_cutoff_release()",
209 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
210 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
211 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
212 - Fixed built-in function "change_play_pos()" not having accepted metric
213 prefixes at all.
214 - Fixed the following built-in functions having misinterpreted values given
215 with unit type (for their 2nd argument) as if they were relative values
216 (that is as if they were passed without a unit type): "change_attack()",
217 "change_decay()", "change_release()", "change_cutoff_attack()",
218 "change_cutoff_decay()", "change_cutoff_release()".
219 - Fixed the following built-in functions having applied completely wrong
220 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
221 respective EGs being their modulation sink assume uint data type with
222 value range 0..1000 instead of 0.0..1.0.
223 - Added individual parse-time checks of function arguments for the following
224 built-in functions: "play_note()", "note_off()", "set_event_mark()",
225 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
226 "change_decay()", "change_release()", "change_cutoff_attack()",
227 "change_cutoff_decay()", "change_cutoff_release()",
228 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
229 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
230 "change_pan_time()".
231 - Don't abort function call if unit type was used and at the same time
232 'final' operator was omitted for the primary value argument of the
233 following built-in functions: "change_cutoff()", "change_attack()",
234 "change_decay()", "change_release()", "change_cutoff_attack()",
235 "change_cutoff_decay()", "change_cutoff_release()",
236 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
237 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
238 "change_pan_time()", instead imply 'final'ness at runtime and raise an
239 appropriate parser warning at parse time.
240 - Added built-in real number functions "round()", "ceil()", "floor()",
241 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
242 "cos()", "tan()", "asin()", "acos()", "atan()".
243 - Added built-in script real number constant "~NI_MATH_PI".
244 - Added built-in script real number constant "~NI_MATH_E".
245 - NKSP language: Allow unary '+' operator.
246 - Added built-in script functions "msb()" and "lsb()".
247 - NKSP language: Added support for RPN event handler
248 ("on rpn ... end on" in instrument scripts).
249 - NKSP language: Added support for NRPN event handler
250 ("on nrpn ... end on" in instrument scripts).
251 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
252 may be read from the new RPN/NRPN script handlers to get the (N)RPN
253 parameter that had been changed and its new value.
254 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
255 which are identifying the new (N)RPN handlers as such at script runtime.
256 - Implemented built-in script function "set_rpn()".
257 - Implemented built-in script function "set_nrpn()".
258 - Fix: built-in functions returning an array type were broken and caused a
259 crash when the built-in function's (supposed to be array) result value was
260 used by the script VM.
261 - Removed upper value constraint for 2nd argument of built-in functions
262 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
263 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
264 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
265 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
266 the LFO frequency / resonance / cutoff frequency.
267 - Reduced code involved for parsing NKSP variable declarations by using 2
268 generalized grammar rules with optional components (i.e. optional value
269 assignment and optional variable qualifiers) instead of previous linear
270 combinations of grammar rules, which also fixes some edge case.
271 - NKSP language parser: track code block locations also by a) raw byte
272 position in NKSP source code string and b) length of that code block in
273 bytes (along to the already existing code block tracking by line/column);
274 and added appropriate new members to public C++ API classes like
275 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
276 - NKSP language: Added support for 'patch' variable qualifier (capture their
277 locations and allow replacement of their assignment expression via VM C++
278 API).
279 - Fixed incorrect EG times if standard measuring unit was passed to built-in
280 functions "change_attack()", "change_decay()" or "change_release()".
281 - Fixed intermediate function result values never having reflected any
282 standard measuring unit type.
283 - Fixed re-entrant issue with function calls which caused wrong result
284 values if the same function was called multiple times in a term
285 (specifically if metric prefixes were used).
286 - NKSP language: Just throw a warning, not an error if an array variable of
287 size zero was declared.
288 - NKSP language: Allow omitting explicit array size on array variable
289 declaration if combined with immediate value assignment
290 (e.g. declare %foo[] := ( 1, 2, 3 ) ).
291 - NKSP language: emit warning if an array variable was declared with bigger
292 array size than amount of initial values been assigned, and initialize the
293 missing array elements with zero in this case.
294 - Fixed built-in NKSP exit() function to behave as return statement.
295 - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
296 data type.
297 - NKSP VM: Fixed the "release" handler being executed too often under
298 certain situations if polyphonic data was passed from "note" handler to
299 "release" handler.
300 - Fixed memory leak in NKSP parser: string tokens were allocated as C
301 strings and never freed.
303 * test cases:
304 - Fixed compiler errors in test cases.
305 - Updated README for how to compile & run test cases.
306 - Updated test case
307 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
308 expected behaviour of the Mutex class implementation (recursive
309 mutex type).
310 - Added test cases for NKSP core language aspects and core built-in
311 functions.
312 - Fixed thread tests segfaulting on Linux.
313 - NKSP: Added real number test cases for built-in functions exit(),
314 int_to_real(), real(), real_to_int() and int(), as well as for the
315 plus, minus and negate language operators.
316 - Added massive amount of NKSP test cases for standard measuring units and
317 'final' operator usage cases.
318 - Added NKSP test cases for (floating point tolerance aware) real number
319 equalness / unequalness comparison.
320 - Added NKSP int array and real array tests for value assignment and
321 initialization of arrays.
322 - Added NKSP test cases for built-in functions "round()", "ceil()",
323 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
324 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
325 - Added NKSP test cases for unary '+' operator.
326 - Added NKSP test cases for core built-in variables.
327 - Added thorough NKSP test cases for variable declarations.
329 * GigaStudio/Gigasampler format engine:
330 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
331 behaviour for start_level_mid.
332 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
333 level (see discussion "GigaStudio LFO compatibility" on mailing list
334 from 2019-09-26 for details).
335 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
336 see discussion "GigaStudio LFO compatibility" on mailing list from
337 2019-09-26 for details).
338 - Format extension: Added support for different LFO wave forms (currently
339 either sine [default], triangle, saw or square).
340 - Format extension: Added support for LFO phase displacement (0��..360��).
341 - Format extension: Added support for flipping LFO polarity on LFO 3
342 (in the original gig format this was only available for LFO 1 and LFO 2).
343 - Format extension: Support for additional filter types:
344 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
345 bandreject 2-pole.
346 - Fixd potential crash with polynomial interpolator and max. pitch.
347 - If minimum cutoff is defined, remap cutoff controller CC values to really
348 span the entire possible cutoff range (and avoiding a dead controller
349 zone).
350 - Implemented support for loading instrument scripts with 'patch' variables
351 (by patching these script variables with potentially overridden ones by
352 gig Instrument).
354 * SFZ format engine:
355 - Fixed support for regions with loccN/hiccN conditions on more than one
356 MIDI controller.
357 - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
358 'xfin_lovel' (patch by Christian Czezatke).
360 * Benchmarks:
361 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
362 algorithm (since result of 2nd run was not accumulated).
363 - Added benchmark for saw wave (benchmarks/saw.cpp).
364 - Added benchmark for sine wave (benchmarks/sine.cpp).
365 - Added benchmark for square wave (benchmarks/square.cpp).
366 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
367 which are large enough on modern systems.
369 Version 2.1.1 (27 Jul 2019)
371 * Real-time instrument scripts:
372 - Fixed behavior of built-in NKSP functions change_sustain(),
373 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
374 and change_cutoff_release().
376 * general changes:
377 - Only play release trigger samples on sustain pedal up if this behaviour
378 was explicitly requested by the instrument (otherwise only on note-off).
379 - Fixed compiler warnings.
380 - Fixed compilation error when cross-compiling to Mac.
381 - FX Sends: Provide more useful error messages on routing problems
382 (see bug #169).
383 - LSCP doc: Be more clear describing the two distinct approaches
384 of using external vs. internal effects (see bug #169).
385 - "optional" class: Fixed comparison operators.
387 * Gigasampler/GigaStudio format engine:
388 - Format extension: If requested by instrument then don't play release
389 trigger sample on note-off events.
391 * SFZ format engine:
392 - Fixed memory leak when releasing samples
393 (fixes bug #307, patch by Jacek Roszkowski)
394 - Fixed potential crash when a sample is shared by more than one region
395 (fixes bug #308, patch by Jacek Roszkowski).
396 - Opcode 'sample': Added support for built-in sample '*silence'
397 (fixes bug #310, patch by Jacek Roszkowski).
399 Version 2.1.0 (25 Nov 2017)
401 * SFZ format engine:
402 - added support for <global>, <master> and #define (patch by Alby M)
403 - Removed code duplication in SFZ file loading code.
404 - Added support for sfz extension opcode 'script' which may be used to
405 load real-time instrument script file (NKSP script language).
406 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
407 - Fixed unintended volume fade-in of voices under certain conditions.
408 - sfz parser: allow missing space between header and opcode
410 * Gigasampler/GigaStudio format engine:
411 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
412 cutoff settings.
413 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
414 all if an up-pitch of more than 40 semi tones was requested (I don't
415 think there is any stock gig sound that requires this behavior to
416 resemble its original sound).
417 - Added support for controlling whether the individual EGADSR stages may
418 be aborted (as LinuxSampler extension to the original GigaStudio 4
419 format).
421 * general changes:
422 - fixed printf type errors (mostly in debug messages)
423 - use unique_ptr instead of auto_ptr when building with C++11
424 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
425 allowing to sort data efficiently in real-time safe manner.
426 - RTList class: added methods for moving/inserting elements to arbitrary
427 position within a list.
428 - RTList class: added method fromPtr() for creating an Iterator object from
429 a raw element pointer.
430 - Attempt to partly fix resetting engine channels vs. resetting engine, an
431 overall cleanup of the Reset*(), ConnectAudioDevice(),
432 DisconnectAudioDevice() API methods would still be desirable though,
433 because the current situation is still inconsistent and error prone.
434 - Active voices are now internally grouped to "Note" objects, instead of
435 being directly assigned to a keyboard key. This allows more fine graded
436 processing of voices, which is i.e. required for certain instrument
437 script features.
438 - Fix: Release trigger voices were not spawned on sustain pedal up
439 (CC #64) events.
440 - Fix: Release trigger voices can now also distinguish correctly between
441 note-off and sustain pedal up events.
442 - All engines: Increased ramp speed of volume smoother and pan smoother
443 (while slow rate of crossfade smoother is preserved) to allow quick
444 volume and pan changes by instrument scripts for instance.
445 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
446 properly and thus were ignored for certain uses.
447 - Added new C++ API method
448 VirtualMidiDevice::SendChannelPressureToSampler().
449 - windows, 32-bit: fixed potential crashes by making sure the stack in
450 sub threads is 16-byte aligned
451 - fixed numerous compiler warnings
452 - Fixed invalid (note-on) event ID being assigned to new Note objects.
453 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
454 fixes potential undefined behavior.
455 - Fixed Note object leak when triggering notes on keys which did not
456 have a valid sample mapped (fixes bug #252).
457 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
458 - linuxsampler binary fix: option --create-instruments-db ignored
459 subsequent optional argument due to glibc's implementation oddity
460 which expects a "=" sign, but no space between them.
462 * packaging changes:
463 - removed unnecessary dependency to libuuid
464 (originated by libgig's usage of it)
465 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
466 auto detect whether it (sh/c)ould output its messages in color.
467 - Debian: Fixed packaging error about invalid "Source-Version"
468 substitution variable.
469 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
470 - Debian: Added build dependency to libsqlite3-dev for building
471 linuxsampler with instruments DB support.
473 * Real-time instrument scripts:
474 - Implemented scheduler for delayed MIDI events and for suspended scripts.
475 - Built-in script function "wait()": implemented support for function's
476 "duration-us" argument, thus scripts using this function are now
477 correctly resumed after the requested amount of microseconds.
478 - Built-in script function "play_note()": implemented support for
479 function's "duration-us" argument, thus notes triggered with this
480 argument are now correctly released after the requested amount of
481 microseconds.
482 - Fix: script events were not cleared when engine channel was reset,
483 potentially causing undefined behavior.
484 - Fixed crash which happened when trying to reference an undeclared
485 variable.
486 - Built-in script function "play_note()": Added support for passing
487 special value -1 for "duration-us" argument, which will cause the
488 triggered note to be released once the original note was released.
489 - Instrument script classes now exported with the liblinuxsampler C++ API.
490 - Added new API method ScriptVM::syntaxHighlighting() which provides
491 a convenient syntax highlighting backend for external instrument
492 script editor applications.
493 - Added new C++ API class "ScriptVMFactory".
494 - Extended parser issues to provide not only first line and first
495 column, but also last line and last column of issue (thus marking
496 the precise span of the issue within the source code).
497 - Reload script automatically after being modified by an instrument
498 editor.
499 - NKSP language grammar correction: allow empty event handler bodies
500 like "on note end on".

506 - Implemented built-in script function "event_status()".
507 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
508 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
509 "event_status()" function.
510 - NKSP language: Added support for bitwise operators ".or.", ".and."
511 and ".not.".
512 - NKSP language scanner: Fixed IDs matching to require at least one
513 character (i.e. when matching function names or variable names).
514 - NKSP language scanner: disabled unusued rules.
515 - Fixed behavior of play_note() and note_off() functions which must
516 be distinguished engine internally from "real" MIDI note on/off
517 events in order to avoid misbehaviors like hanging notes.
518 - Implemented built-in script variable "$KSP_TIMER".
519 - Implemented built-in script variable "$NKSP_REAL_TIMER".
520 - Implemented built-in script variable "$NKSP_PERF_TIMER".
521 - Implemented built-in script variable "$ENGINE_UPTIME".
522 - Implemented built-in script function "inc()".
523 - Implemented built-in script function "dec()".
524 - NKSP language fix: division expressions were evaluated too often.
525 - NKSP language fix: string concatenation operator was right
526 associative instead of left (to right).
527 - NKSP language correction: allow empty statements in entire language
528 (i.e. "if end if").
529 - Implemented built-in script function "stop_wait()".

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

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

636 - Added built-in script function "callback_status()".
637 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
638 - Added built-in constant $CALLBACK_STATUS_QUEUE.
639 - Added built-in constant $CALLBACK_STATUS_RUNNING.
640 - Removed max. value limitation of built-in functions "change_attack()",
641 "change_decay()" and "change_release()" to i.e. allow passing 2000000
642 for doubling the respective time.
643 - NKSP script editor syntax highlighting API: Fixed app termination due
644 to a lexer start condition stack underrun.
645 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
646 USE_CODE_IF_NOT() preprocessor statements.
647 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
648 can be set to disable all subsequent built-in "message()" function calls
649 on preprocessor level.
650 - Implemented built-in script function "change_sustain()".
651 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

662 * Instruments DB:
663 - Fixed memory access bug of general DB access code which lead to
664 undefined behavior.
665 - Cleanup of instruments DB file creation and opening code.
666 - The instrument DB path of linuxsampler's --create-instruments-db argument
667 is now optional, if it is missing, then a default location is used.
668 - Added support for scanning SFZ (.sfz) files.
669 - Added support for scanning Sound Font (.sf2) files.
670 - Fixed undefined DB transaction behavior.
672 Version 2.0.0 (15 July 2015)
674 * packaging changes:
675 - fixed building with newer MinGW-w64
676 - Mac OS X: support the new dir for Core Audio SDK
677 - Mac OS X: fixed building outside source directory
678 - made sure all source files for hostplugins are included when
679 doing "make dist"
680 - removed empty directories left from the cvs to svn migration
681 - fixed compilation with gcc 4.6.1
682 - another "make dist" fix, for the LV2 plugin
683 - made --enable-pthread-testcancel default on Mac OS X
684 - minor Makefile fix for building lscpparser when build and source
685 directories are separate
686 - Mac OS X: made it possible to specify plugin installation dir to
687 configure
688 - Mac OS X: Makefile fix for the install-strip target
689 - fixed compilation with gcc 4.7
690 - fixed configure script error with old autoconf versions
691 - lsatomic.h: use gcc provided atomic functions if building with
692 gcc 4.7 and C++11
693 - modernized configure script
694 - fixed linkage error when building with
695 LDFLAGS="-Wl,--no-undefined" (#190)
696 - fixed compilation with Clang 3.2
697 - removed usage of deprecated Automake variable INCLUDES
698 - fixed building with C++11
699 - build fix: ChangeFlagRelaxed.h was missing in makefile
700 - build fix: libsndfile compiler flags were missing in some
701 makefiles
702 - fix for building with bison 3.0 (#202)
703 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
704 on the process's main thread
705 - fixed build error on newer MinGW
706 - support building with older jack versions
707 - support building with spaces in vst sdk path
708 - enabled automake 'subdir-objects' option and moved external
709 source references (vst, au, asio) from makefiles to cpp files,
710 in order to get rid of warnings from automake 1.14
712 * general changes:
713 - Refactoring: moved the independent code from
714 the Gigasampler format engine to base classes
715 - command line option '--profile' is currently disabled, since the
716 respective profiling code is currently broken
717 - Introduced support for optional environment variable
718 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
719 where the sampler shall look for instrument editor plugins
720 (patch by Luis Garrido, slightly modified).
721 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
722 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
723 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
724 note (in this implementation of the sampler its simply hard routed to
725 the 1st effect send of the sampler channel, no matter what the actual
726 effect type is)
727 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
728 note (in this implementation of the sampler its simply hard routed to
729 the 2nd effect send of the sampler channel, no matter what the actual
730 effect type is)
731 - implemented support for internal LADSPA effects
732 - raised limit of program change queue from 100 to 512
733 (as suggested by Alex Stone)
734 - implemented sine LFO, pulse LFO and saw LFO
735 - experimental support for per voice equalization
736 - added command line option --exec-after-init
737 - Introduced new C++ API method:
738 EngineChannel::InstrumentFileName(int index)
739 allowing to retrieve the whole list of files used for the loaded
740 instrument on an engine channel (a.k.a. part). Some GigaStudio
741 instruments for example are splitted over several files like
742 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
743 - Added new C++ API method Sampler::GetGlobalMaxVoices().
744 - Added new C++ API method Sampler::GetGlobalMaxStreams().
745 - Added new C++ API method Sampler::SetGlobalMaxVoices().
746 - Added new C++ API method Sampler::SetGlobalMaxStreams().
747 - Various "const" and "restrict" optimizations.
748 - all engines: add pan CC value to instrument pan parameter before
749 applying panning, instead of using two separate pan functions in
750 series (#182)
751 - added a lock guard class for exception safe mutex handling and
752 used it everywhere appropriate
753 - Immediately apply scale tuning changes to active voices.
754 - Exposed scale tuning to C++ API (along to the already existing standard
755 SysEx way).
756 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
757 and broken for ppc64. (Seq_cst loads and stores are actually not
758 used in LS, so the bug wasn't noticable.)
759 - lsatomic.h: added ARMv7 support
760 - Added support for multiple MIDI input ports per sampler channel (and
761 added various new C++ methods for this new feature / design change, old
762 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
763 as deprecated but are still there and should provide full behavior
764 backward compatibility).
765 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
766 unsafe and caused compilation error with clang 2.x).
767 - Bugfix: only process the latest MIDI program change event.
768 - Introducing the LSCP shell, which provides convenient control of the
769 sampler from the command line by providing LSCP aware features.
770 - VirtualMidiDevice: Added support for program change.
771 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
772 - VirtualMidiDevice: Added support for pitch bend.
773 - Aftertouch: extended API to explicitly handle channel pressure and
774 polyphonic key pressure events (so far polyphonic pressure was not
775 supported at all, and channel pressure was rerouted as CC128 but not
776 used so far).
777 - Added initial support for real-time instrument scripts. The script VM
778 code is shared by all sampler engine implemementations, however only the
779 gig file format currently provides support for storing instrument scripts
780 (as LinuxSampler extension to the original GigaStudio 4 format).
782 * Gigasampler format engine:
783 - implemented the "round robin keyboard" dimension
784 - fixed round robin and random dimensions for cases when number of
785 dimension zones is not a power of two
786 - made round robin use a counter for each region instead of each
787 key
788 - bugfix: pitch LFO controller "internal+aftertouch" was broken
789 - bugfix: filter keyboard tracking was broken
790 - filter performance fix (an unnecessary copy was made of the
791 filter parameters in each sub fragment)
792 - handle special case when pan parameter in gig file has max or
793 min value
794 - Exclusive Groups: don't ever stop voices of the same note,
795 doesn't sound naturally with a drumkit
796 - fixed EG1 modulation when attack or release is zero
797 - Fixed support for 'aftertouch' attenuation controller.
798 - Fixed crash that happened with velocity split sounds under certain
799 conditions (see also previous commit on libgig).
800 - fixed behaviour of filter LFO
802 * SFZ format engine:
803 - Initial implementation (not usable yet)
804 - added support for v2 multiple stage envelope generators
805 - added a fine-tuned v1 envelope generator instead of using the
806 one from the gig engine
807 - fixed memory leak and memory handling errors
808 - added support for trigger=first, trigger=legato and sw_previous
809 - allow non-numerical key values ("C#4" for example)
810 - "key" opcode now sets pitch_keycenter too
811 - fixed error when unloading instrument with same sample used by
812 multiple regions
813 - added some opcode aliases, like loopmode for loop_mode, to be
814 more compatible
815 - added support for trigger=release and rt_decay
816 - added support for off_mode=normal
817 - added support for random, seq_position, seq_length and volume
818 - added v1 LFO opcodes to parser (no support in engine yet)
819 - added support for amp_veltrack and amp_velcurve_N
820 - fine-tuned the default velocity curve
821 - added support for transpose
822 - fixed crash when using sw_down/up
823 - improved logic for sw_lokey/hikey/up/down/last
824 - added more v1 aliases to parser
825 - reduced memory usage for sfz data
826 - RT-safeness: avoid malloc in audio thread
827 - fixed a bug that could cause voice stealing to fail
828 - optimized sample lookup
829 - improved support for exclusive groups (group, off_by and
830 off_mode)
831 - added support for controller triggered regions (on_locc/on_hicc)
832 - added support for loop_mode=one_shot
833 - fixed playback of 16 bit wav files on big endian CPUs
834 - added support for Ogg Vorbis sample files
835 - use loop markers from sample file if loop_start and loop_end are
836 not set in sfz file
837 - implemeted filters. Filter types: lowpass, bandpass, bandreject
838 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
839 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
840 cutoff_cc, cutoff_chanaft.
841 - bugfix: zero ampeg_sustain didn't work
842 - added support for velocity effect on amplifier envelope time
843 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
844 ampeg_vel2release)
845 - added support for EG hold (ampeg_hold)
846 - added support for sample offset (offset)
847 - use the newly introduced signal units model

853 pitcheg_vel2attack, pitcheg_vel2hold, pitcheg_vel2decay,
854 pitcheg_vel2sustain, pitcheg_vel2release, pitcheg_depth

1029 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1030 the driver will automatically connect to other CoreMIDI clients' ports
1031 (e.g. external MIDI devices being attached to the Mac)
1032 - added support for MIDI note on velocity filter
1033 - CoreMIDI: fixed memory deallocation error
1034 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
1035 virtual keyboards in frontends / instrument editors being stuck.

1170 - bugfix: calling SET VOICES (which Fantasia does on start and
1171 refresh) could cause instruments to be unloaded
1172 - Mac OS X: fixed name collision of enum in EffectControl and
1173 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp

1178 after MIDI/audio device creation failure
1179 - When creating MIDI instrument map entries with "PERSISTENT" type, the

1204 crashes and noise on such transitions).
1205 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1206 (fixes #208)
1207 - Fixed bug in LSCP grammar definition which caused a statement like
1208 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1209 practically irrelevant, however it caused problems with the new LSCP
1210 shell's auto completion feature).
1211 - Fixed MIDI program change messages being ignored if quickly executed
1212 after each other (fixes #231).
1214 Version 1.0.0 (31 July 2009)
1216 * packaging changes:

1229 directory of liblinuxsampler dll (look in the same directory and one
1230 directory above)
1231 - configure script fix: removed unconditional use of SSE
1232 - fixed building with sqlite installed in a non-standard directory
1233 - when cross-compiling, don't try to create instruments.db
1234 - fix for new mingw-w64 version, which has usleep
1236 * general changes:
1237 - bugfix: on some POSIX systems instrument editor plugins refused to
1238 load as we used a non-portable Linux specific struct field
1239 (fixes bug #70, patch by Ronald Baljeu)
1240 - fixed endless loop which occured when loading an instrument editor
1241 plugin DLL on Windows systems failed
1242 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1243 - optimized the SynchronizedConfig class so it doesn't wait
1244 unnecessarily long after an update

1246 events (e.g. to highlight the pressed keys on the virtual keyboard
1247 of gigedit)
1248 - added support for triggering notes by instrument editors (see above)
1249 - be verbose on DLL load errors (on Linux)
1250 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1251 is only used by very few systems, most pick the int math
1252 implementation, which is usually faster)
1253 - fixes for audio drivers with varying buffer sizes
1254 - experimental support for running LinuxSampler as a DSSI, LV2 and
1255 VST plugin
1256 - notification events for stream/voice count statistics are now sent
1257 only when there are actual changes
1258 - added memory ordering constraints to improve stability on
1259 multi-core and multi-cpu systems
1260 - maximum voices and disk streams can now be altered at runtime
1261 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1262 - automatic stacktrace mechanism is now turned off by default and can
1263 be switched on by command line option "--stacktrace" (the automatic
1264 stacktrace mechanism seems to be broken on most systems at the moment)
1265 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1266 a pointer to the launched InstrumentEditor object
1267 - added optional 3rd party user data parameter for following
1268 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1269 InstrumentEditor::Launch(),
1270 InstrumentManager::LaunchInstrumentEditor()
1271 - theoretical fix: made SynchronizedConfig follow C++0x memory
1272 model more strictly
1273 - fixes for using large audio device buffers
1274 - Windows: add the installation directory to the DLL search path
1275 when loading an editor plugin (solves problems with VST and
1276 gigedit on systems with other GTK versions installed)
1277 - updated linuxsampler man page
1279 * audio driver:
1280 - removed the nonsense audio channel constraint (which was hard coded to
1281 max. 100 audio channels) for most audio drivers
1282 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1283 opposed to the LSCP specs
1284 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1285 reflected the wrong value
1286 - fixed a memory management bug in ASIO driver
1287 - Makefile fix: JACK_CFLAGS wasn't used
1288 - JACK: use jack_client_open instead of the deprecated
1289 jack_client_new

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