ConstCapacityArray class: fix bug in remove() method

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

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

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

575 - Implemented built-in script function "change_amp_lfo_freq()".
576 - Implemented built-in script function "change_pitch_lfo_depth()".
577 - Implemented built-in script function "change_pitch_lfo_freq()".
578 - Implemented built-in script function "change_vol_time()".
579 - Implemented built-in script function "change_tune_time()".
580 - Implemented built-in script function "fade_in()".
581 - Implemented built-in script function "fade_out()".
582 - Fixed acceptance of wrong data type of parameters passed to built-in
583 script functions "change_vol()", "change_tune()", "change_pan()",
584 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
585 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
586 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
587 - Added built-in script function "get_event_par()" and implemented some
588 of its possible parameter selections.
589 - Added built-in script function "set_event_par()" and implemented some
590 of its possible parameter selections.
591 - Fixed a bunch of scheduler time related bugs.
592 - Fixed polyphonic variables not being reset to zero after usage.
593 - Built-in "ignore_event()" function: argument is now optional, like with
594 built-in function "ignore_controller()".
595 - Implemented built-in script function "change_velo()".
596 - Implemented built-in script function "change_note()".
597 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
598 intuitive behavior if used in combination with "change_vol_time()" or
599 "change_tune_time()" respectively: now tuning/volume changes are only
600 assigned (without delay) immediately to a new note if the respective
601 timing function has not been called before, otherwise the volume/tuning
602 changes are automatically faded (before, only the event's time stamp was
603 relevant).
604 - Implemented built-in script function "array_equal()".
605 - Implemented built-in script function "search()".
606 - Implemented built-in script function "sort()".
607 - NKSP Fix: Never suspend "init" event handlers.
608 - Implemented built-in script function "same_region()" (currently only
609 available for gig format engine).
610 - Added built-in script constant "$NKSP_LINEAR".
611 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
612 - Implemented built-in script function "change_vol_curve()".
613 - Implemented built-in script function "change_tune_curve()".
614 - built-in "play_note()" function now supports a sample playback start
615 offset with argument 3, where special value -1 means to use the regular
616 sample offset as defined by the instrument file.
617 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
618 - Built-in variable $EVENT_NOTE is now a read-only variable.
619 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
620 - built-in "play_note()" function now accepts -2 for its fourth argument
621 (note duration) which means the life time of the note shall be sticked
622 to the requested note number of argument 1.
623 - Fix: built-in "play_note()" function now returns 0 as result value if
624 -1 was passed for its fourth argument (note duration) and the respective
625 parent note is already gone.
626 - Implemented built-in script function "change_play_pos()".
627 - NKSP language: Added support for user declared const array variables.
628 - NKSP language: Raise parser warning if array variable is accessed with
629 an index that exceeds the array's size.
630 - NKSP language fix: Unknown characters were not handled correctly.
631 - NKSP language: Added support for "synchronized .. end synchronized"
632 code blocks.
633 - Implemented built-in script function "abort()" which allows to abort
634 another script handler by passing its callback ID.
635 - Fixed potential memory access bug and potential undefined behavior of
636 "init" event handlers.
637 - Print a time stamp along to each call of built-in function "message()".
638 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
639 to retrieve all code blocks filtered out by the preprocessor.
640 - Added built-in script function "fork()".
641 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
642 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
643 - Fixed potential crash when accessing dynamic built-in array variables.
644 - Added built-in script function "callback_status()".
645 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
646 - Added built-in constant $CALLBACK_STATUS_QUEUE.
647 - Added built-in constant $CALLBACK_STATUS_RUNNING.
648 - Removed max. value limitation of built-in functions "change_attack()",
649 "change_decay()" and "change_release()" to i.e. allow passing 2000000
650 for doubling the respective time.
651 - NKSP script editor syntax highlighting API: Fixed app termination due
652 to a lexer start condition stack underrun.
653 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
654 USE_CODE_IF_NOT() preprocessor statements.
655 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
656 can be set to disable all subsequent built-in "message()" function calls
657 on preprocessor level.
658 - Implemented built-in script function "change_sustain()".
659 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
660 to avoid the editor app to crash on ill-formed text input.

668 - Added built-in script function "change_cutoff_lfo_freq()".
669
670 * Instruments DB:
671 - Fixed memory access bug of general DB access code which lead to
672 undefined behavior.
673 - Cleanup of instruments DB file creation and opening code.
674 - The instrument DB path of linuxsampler's --create-instruments-db argument
675 is now optional, if it is missing, then a default location is used.
676 - Added support for scanning SFZ (.sfz) files.
677 - Added support for scanning Sound Font (.sf2) files.
678 - Fixed undefined DB transaction behavior.
679

692 - minor Makefile fix for building lscpparser when build and source
693 directories are separate
694 - Mac OS X: made it possible to specify plugin installation dir to
695 configure
696 - Mac OS X: Makefile fix for the install-strip target
697 - fixed compilation with gcc 4.7
698 - fixed configure script error with old autoconf versions
699 - lsatomic.h: use gcc provided atomic functions if building with
700 gcc 4.7 and C++11
701 - modernized configure script
702 - fixed linkage error when building with
703 LDFLAGS="-Wl,--no-undefined" (#190)
704 - fixed compilation with Clang 3.2
705 - removed usage of deprecated Automake variable INCLUDES
706 - fixed building with C++11
707 - build fix: ChangeFlagRelaxed.h was missing in makefile
708 - build fix: libsndfile compiler flags were missing in some
709 makefiles
710 - fix for building with bison 3.0 (#202)
711 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
712 on the process's main thread
713 - fixed build error on newer MinGW
714 - support building with older jack versions
715 - support building with spaces in vst sdk path
716 - enabled automake 'subdir-objects' option and moved external
717 source references (vst, au, asio) from makefiles to cpp files,
718 in order to get rid of warnings from automake 1.14
719
720 * general changes:
721 - Refactoring: moved the independent code from
722 the Gigasampler format engine to base classes
723 - command line option '--profile' is currently disabled, since the
724 respective profiling code is currently broken
725 - Introduced support for optional environment variable
726 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
727 where the sampler shall look for instrument editor plugins
728 (patch by Luis Garrido, slightly modified).
729 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
730 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
731 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
732 note (in this implementation of the sampler its simply hard routed to
733 the 1st effect send of the sampler channel, no matter what the actual
734 effect type is)
735 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
736 note (in this implementation of the sampler its simply hard routed to
737 the 2nd effect send of the sampler channel, no matter what the actual
738 effect type is)
739 - implemented support for internal LADSPA effects
740 - raised limit of program change queue from 100 to 512
741 (as suggested by Alex Stone)
742 - implemented sine LFO, pulse LFO and saw LFO
743 - experimental support for per voice equalization
744 - added command line option --exec-after-init
745 - Introduced new C++ API method:
746 EngineChannel::InstrumentFileName(int index)
747 allowing to retrieve the whole list of files used for the loaded
748 instrument on an engine channel (a.k.a. part). Some GigaStudio
749 instruments for example are splitted over several files like
750 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
751 - Added new C++ API method Sampler::GetGlobalMaxVoices().
752 - Added new C++ API method Sampler::GetGlobalMaxStreams().
753 - Added new C++ API method Sampler::SetGlobalMaxVoices().
754 - Added new C++ API method Sampler::SetGlobalMaxStreams().
755 - Various "const" and "restrict" optimizations.
756 - all engines: add pan CC value to instrument pan parameter before
757 applying panning, instead of using two separate pan functions in
758 series (#182)
759 - added a lock guard class for exception safe mutex handling and
760 used it everywhere appropriate
761 - Immediately apply scale tuning changes to active voices.
762 - Exposed scale tuning to C++ API (along to the already existing standard
763 SysEx way).
764 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
765 and broken for ppc64. (Seq_cst loads and stores are actually not
766 used in LS, so the bug wasn't noticable.)
767 - lsatomic.h: added ARMv7 support
768 - Added support for multiple MIDI input ports per sampler channel (and
769 added various new C++ methods for this new feature / design change, old
770 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
771 as deprecated but are still there and should provide full behavior
772 backward compatibility).
773 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
774 unsafe and caused compilation error with clang 2.x).
775 - Bugfix: only process the latest MIDI program change event.
776 - Introducing the LSCP shell, which provides convenient control of the
777 sampler from the command line by providing LSCP aware features.
778 - VirtualMidiDevice: Added support for program change.
779 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
780 - VirtualMidiDevice: Added support for pitch bend.
781 - Aftertouch: extended API to explicitly handle channel pressure and
782 polyphonic key pressure events (so far polyphonic pressure was not
783 supported at all, and channel pressure was rerouted as CC128 but not
784 used so far).
785 - Added initial support for real-time instrument scripts. The script VM
786 code is shared by all sampler engine implemementations, however only the
787 gig file format currently provides support for storing instrument scripts
788 (as LinuxSampler extension to the original GigaStudio 4 format).
789
790 * Gigasampler format engine:
791 - implemented the "round robin keyboard" dimension
792 - fixed round robin and random dimensions for cases when number of
793 dimension zones is not a power of two
794 - made round robin use a counter for each region instead of each
795 key
796 - bugfix: pitch LFO controller "internal+aftertouch" was broken
797 - bugfix: filter keyboard tracking was broken
798 - filter performance fix (an unnecessary copy was made of the
799 filter parameters in each sub fragment)
800 - handle special case when pan parameter in gig file has max or
801 min value
802 - Exclusive Groups: don't ever stop voices of the same note,
803 doesn't sound naturally with a drumkit
804 - fixed EG1 modulation when attack or release is zero
805 - Fixed support for 'aftertouch' attenuation controller.
806 - Fixed crash that happened with velocity split sounds under certain
807 conditions (see also previous commit on libgig).
808 - fixed behaviour of filter LFO
809
810 * SFZ format engine:
811 - Initial implementation (not usable yet)

816 - added support for trigger=first, trigger=legato and sw_previous
817 - allow non-numerical key values ("C#4" for example)
818 - "key" opcode now sets pitch_keycenter too
819 - fixed error when unloading instrument with same sample used by
820 multiple regions
821 - added some opcode aliases, like loopmode for loop_mode, to be
822 more compatible
823 - added support for trigger=release and rt_decay
824 - added support for off_mode=normal
825 - added support for random, seq_position, seq_length and volume

840 - added support for loop_mode=one_shot
841 - fixed playback of 16 bit wav files on big endian CPUs
842 - added support for Ogg Vorbis sample files
843 - use loop markers from sample file if loop_start and loop_end are
844 not set in sfz file
845 - implemeted filters. Filter types: lowpass, bandpass, bandreject
846 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
847 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
848 cutoff_cc, cutoff_chanaft.
849 - bugfix: zero ampeg_sustain didn't work
850 - added support for velocity effect on amplifier envelope time
851 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
852 ampeg_vel2release)
853 - added support for EG hold (ampeg_hold)
854 - added support for sample offset (offset)

1037 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1038 the driver will automatically connect to other CoreMIDI clients' ports
1039 (e.g. external MIDI devices being attached to the Mac)
1040 - added support for MIDI note on velocity filter
1041 - CoreMIDI: fixed memory deallocation error
1042 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1212 crashes and noise on such transitions).
1213 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1214 (fixes #208)
1215 - Fixed bug in LSCP grammar definition which caused a statement like
1216 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1217 practically irrelevant, however it caused problems with the new LSCP
1218 shell's auto completion feature).
1219 - Fixed MIDI program change messages being ignored if quickly executed
1220 after each other (fixes #231).
1221
1222 Version 1.0.0 (31 July 2009)
1223
1224 * packaging changes:
1225 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1235 - minor fix in configure for mmsystem.h detection on MinGW
1236 - Windows: look for editor plugins and Fantasia using base
1237 directory of liblinuxsampler dll (look in the same directory and one
1238 directory above)
1239 - configure script fix: removed unconditional use of SSE
1240 - fixed building with sqlite installed in a non-standard directory
1241 - when cross-compiling, don't try to create instruments.db
1242 - fix for new mingw-w64 version, which has usleep
1243
1244 * general changes:
1245 - bugfix: on some POSIX systems instrument editor plugins refused to
1246 load as we used a non-portable Linux specific struct field
1247 (fixes bug #70, patch by Ronald Baljeu)
1248 - fixed endless loop which occured when loading an instrument editor
1249 plugin DLL on Windows systems failed
1250 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1251 - optimized the SynchronizedConfig class so it doesn't wait
1252 unnecessarily long after an update

1254 events (e.g. to highlight the pressed keys on the virtual keyboard
1255 of gigedit)
1256 - added support for triggering notes by instrument editors (see above)
1257 - be verbose on DLL load errors (on Linux)
1258 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1259 is only used by very few systems, most pick the int math
1260 implementation, which is usually faster)
1261 - fixes for audio drivers with varying buffer sizes
1262 - experimental support for running LinuxSampler as a DSSI, LV2 and
1263 VST plugin
1264 - notification events for stream/voice count statistics are now sent
1265 only when there are actual changes
1266 - added memory ordering constraints to improve stability on
1267 multi-core and multi-cpu systems
1268 - maximum voices and disk streams can now be altered at runtime
1269 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1270 - automatic stacktrace mechanism is now turned off by default and can
1271 be switched on by command line option "--stacktrace" (the automatic
1272 stacktrace mechanism seems to be broken on most systems at the moment)
1273 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1274 a pointer to the launched InstrumentEditor object
1275 - added optional 3rd party user data parameter for following
1276 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1277 InstrumentEditor::Launch(),
1278 InstrumentManager::LaunchInstrumentEditor()
1279 - theoretical fix: made SynchronizedConfig follow C++0x memory
1280 model more strictly
1281 - fixes for using large audio device buffers
1282 - Windows: add the installation directory to the DLL search path
1283 when loading an editor plugin (solves problems with VST and
1284 gigedit on systems with other GTK versions installed)
1285 - updated linuxsampler man page
1286
1287 * audio driver:
1288 - removed the nonsense audio channel constraint (which was hard coded to
1289 max. 100 audio channels) for most audio drivers
1290 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1291 opposed to the LSCP specs
1292 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1293 reflected the wrong value
1294 - fixed a memory management bug in ASIO driver
1295 - Makefile fix: JACK_CFLAGS wasn't used
1296 - JACK: use jack_client_open instead of the deprecated
1297 jack_client_new
1298 - added (experimental) CoreAudio driver
1299 - applied old fixes to the ASIO driver that were included in the
1300 previous binary release but accidentally never committed to CVS
1301 (fixes #117)
1302 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1303 win64)
1304 - VST: added support for sample rate and buffer size changes
1305 - VST: close editor (Fantasia) when the VST is removed
1306 - VST: avoid opening Fantasia more than once for each VST instance
1307 - VST: export main function as "main" on Linux too (fix for
1308 energyXT)
1309 - VST: changed number of output channels from one stereo to 16
1310 stereo
1311 - added channel routing, fxsends and midi maps to the settings
1312 stored in the plugin state
1313 - performance optimization of AudioChannel::MixTo() and
1314 AudioChannel::CopyTo() methods using GCC vector exensions
1315 (if available)
1316 - ASIO fixes: avoid initializing the device twice, avoid throwing
1317 exception when getting parameters from a disconnected device
1318
1319 * MIDI driver:
1320 - added JACK MIDI driver
1321 - dispatch bank select as ordinary CC as well, the user might seriously
1322 want to (mis)use it for some purpose ("fixed" in all current MIDI
1323 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1324 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1325 CoreMidi or AU
1326 - fixed mingw-w64 compilation error in MME driver
1327 - made program change handling in MIDI thread real-time safe by
1328 moving the logic to a non-RT thread
1329 - fixed minor memory leak in ALSA driver
1330
1331 * instruments database:
1332 - avoid time consuming samples scanning when adding instruments
1333 to the instruments database
1334 - added support for handling lost files in the instruments database
1335 - Implemented option for adding instruments in separate directories
1336 in the instruments database
1337 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1338 - work-around for missing fnmatch function on Windows to make
1339 instrument database compilable
1340 - added instrument database support on Windows
1341 works with both standalone mode and VST plugin.
1342 the instruments DB file is located in
1343 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1344 databases for each windows user
1345 if no DB is present it automatically creates the .linuxsampler subdir
1346 and then creates an empty DB
1347 - fixed recursive import, which was broken on Windows
1348
1349 * Gigasampler format engine:
1350 - fixed a memory leak that could happen when a channel was deleted
1351 while notes were playing
1352 - made it possible to load an instrument even if the audio thread
1353 isn't running
1354 - added partial support for the "Controller Triggered" MIDI rule,
1355 enough for piano gigs with pedal noise samples
1356 - minor fix: only mark FX sends as being modified if really the
1357 respective FX send MIDI controller was used
1358 - added support for GM global device volume SysEx message
1359 (can be selected at compile time to either apply globally to the
1360 whole sampler [default] or only to the sampler channels that are
1361 connected to the respective MIDI input port the SysEx message arrived
1362 on)
1363 - bugfix: notes triggered at position 0 in the audio buffer were
1364 sometimes wrongly killed in the same buffer, causing no sound to
1365 be played
1366 - added support for chromatic / drumkit mode Roland GS Sysex message
1367 which is usally used to switch a part between chromatic sounds and
1368 drumkit sounds (as opposed to their common default setting of MIDI
1369 part 10 being a drumkit part and all other ones chromatic parts), in
1370 LS however one can switch between the first 16 MIDI instrument maps
1371 defined for the sampler
1372 - made it possible to create multiple sample channels even if the
1373 audio thread isn't running
1374 - fixed crash when removing channel with active voices (#116)
1375 - bugfix: on sample reference changes (instrument editor), only
1376 un-cache the respective sample if it's really not used by any
1377 sampler engine anymore
1378 - re-cache samples in case they were changed by an instrument editor,
1379 e.g. when a sample was added while playing (#82)
1380 - fixed hanging notes which occured when note-off event had the exact
1381 same time stamp as the voice's note-on event and occured both in the
1382 same audio fragment cycle (fixes bug #112)
1383 - added support for the "fine tune" and "pitch bend range"
1384 instrument-level gig parameters
1385 - fixed minor artifacts in pitch bend handling
1386 - added support for GS Reset SysEx message
1387 - allow gig files to use unlimited downward pitch shifting
1388 - added a limit check for upward pitch shifting
1389 - bugfix: sometimes, when playing a note twice fast, the second
1390 note was silent
1391 - fixed crash happening when a pitch bend event arrived at the
1392 same time a new instrument was loading
1393
1394 * LSCP server:
1395 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1396 react on MIDI data arriving on certain sampler channels (so far only
1397 Note-On and Note-Off events are sent via this LSCP event)
1398 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1399 react on MIDI data arriving on certain MIDI input devices (so far only
1400 Note-On and Note-Off events are sent via this LSCP event)
1401 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1402 SET DB_INSTRUMENT FILE_PATH
1403 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1404 frontends to send MIDI messages to specific sampler channel
1405 - added two additional fields to GET FILE INSTRUMENT INFO command -
1406 KEY_BINDINGS and KEYSWITCH_BINDINGS
1407 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1408 was incorrect
1409 - Optimized the retrieval of the MIDI instrument mappings
1410 - added new LSCP command "SET VOICES" to globally alter the maximum
1411 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1412 be triggered respectively
1413 - added new LSCP command "SET STREAMS" to globally alter the maximum
1414 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1415 which will be triggered respectively
1416 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1417 a gigedit file dialog is opened)
1418 - close all connections when LSCPServer is deleted
1419 - hard close of all sockets on exit
1420 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1421 driver
1422
1423 * Bug fixes:
1424 - fixed a crash which occurs when removing a sampler channel waiting
1425 to start instrument loading after another channel
1426 - fixed a crash which occurs when removing a sampler channel with
1427 instrument loading in progress (bug #113)
1428 - fixed termination caused by uncaught exception when adding MIDI
1429 instrument with PERSISTENT load mode
1430 - fixed possible iterator invalidations when resetting the sampler
1431 - fixed memory leaks when issuing the following LSCP commands:
1432 GET AUDIO_OUTPUT_DRIVER INFO
1433 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1434 GET MIDI_INPUT_DRIVER INFO
1435 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1436 - fixed possible compilation error when sqlite is not present
1437 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1438 - fixed crash when changing the audio output device of a sampler
1439 channel with loaded instrument and start playing notes
1440 - fixed endless loop in Engine::SuspendAll() (bug #120)
1441 - fixed a low-level atomic load function that was broken on 64-bit
1442 PowerPC, which probably could cause crashes on that platform
1443 - fixed a memory management error which could cause a crash when a
1444 plugin was unloaded
1445 - bugfix: two private structs had the same name, which could cause
1446 problems if the linker chose the wrong constructor
1447 - fixed low-level ConditionServer usage bug that caused lockups on
1448 Windows
1449
1450
1451 Version 0.5.1 (6 December 2007)
1452
1453 * packaging changes:
1454 - added autoconf checks for pthread library
1455 - added autoconf check for pthread bug found on certain NPTL-enabled
1456 glibc versions (see Gentoo bug report #194076)
1457 - added autoconf checks for MS Windows
1458
1459 * general changes:
1460 - bugfix: the thread used by an editor plugin didn't die when the
1461 editor closed
1462 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1463 out all the space. operator--() did not apply size_mask after
1464 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1465 order to avoid problems with the _NonVolatileReader functions.
1466 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1467 GetWriteSpace(). Since this function is currently only used in
1468 the stream's qsort() compare function, it didn't trigger any
1469 bugs.
1470 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1471 24bit mode too. Faster method to read 24bit words on little
1472 endian machines (x86): replaced 3 byte reads + shifts with a 1
1473 unaligned 32bit read and shift
1474 - experimental support for MS Windows (MIDI input via MME, AUDIO
1475 output via ASIO)
1476 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1477 - support for monitoring the total number of active disk streams
1478 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1479 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1480
1481 * AUDIO driver:
1482 - added Windows ASIO low latency audio driver
1483
1484 * MIDI driver:
1485 - added MME Windows MIDI driver
1486
1487 * LSCP server:
1488 - added support for Windows style path / filenames, however with
1489 forward slash path separators instead of backslash
1490 (i.e. "C:/foo/bar.gig")
1491 - allow naughty liblscp to send non-string device parameters within
1492 apostrophes as well
1493 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1494 "LIST FILE INSTRUMENTS <file>" and
1495 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1496 about an arbitrary instrument file on the system where the sampler is
1497 running on
1498
1499 Version 0.5.0 (15 October 2007)
1500
1501 * packaging changes:
1502 - config.h is not going to be installed along with liblinuxsampler's
1503 API header files anymore
1504 - only the API relevant header (and source) files will be exported to
1505 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1506 - added completely new XCode project files for Mac OSX which is now
1507 capable to execute our autoconf environment, thus no need anymore
1508 to maintain the compile time configuration file (osx/version.h) for
1509 OSX manually (patch by Toshi Nagata)
1510 - fixed buggy boolean --enable-foo / --disable-foo configure script
1511 parameters
1512 - global.h now only covers global definitions that are needed for the
1513 C++ API header files, all implementation internal global definitions
1514 are now in global_private.h
1515 - atomic.h is not exposed to the C++ API anymore
1516 - no need to include config.h anymore for using LS's API header files
1517 - fixed warnings in API doc generation
1518
1519 * general changes:
1520 - replaced the old, confusing MIDI program change mechanism by a
1521 flexible MIDI instrument mapper which allows to map arbitrary
1522 (MIDI bank, MIDI program) pairs with arbitrary
1523 (engine type, instrument file, file index) triplets which will be
1524 loaded on the respective channel when such MIDI program change
1525 messages arrive, beside that, each entry allows to define a life-time
1526 strategy for the instrument, so the user can define whether the
1527 instrument should i.e. be permanently loaded (to be able to switch
1528 quickly among sounds) or i.e. loaded just on demand when the
1529 respective program change arrives (to safe RAM space), as well as a
1530 global volume factor for each entry, so the user can adjust the volume
1531 dynamic of his mapped instrument collection without having to modify
1532 the instrument files, also one can manage arbitrary amount of such
1533 MIDI instrument maps and assign each sampler channel individually
1534 a certain map, so that i.e. separation of normal instruments and
1535 drumkits is possible
1536 - new notification events for tracking changes to audio/MIDI devices,
1537 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1538 - sampler was limited to load max. 200 instruments in the background
1539 due to a constant size RingBuffer FIFO which is now replaced by a
1540 dynamic (unlimited) size std::list FIFO
1541 - added FX sends, these allow to route audio signals to arbitrary audio
1542 output channels for being processed by external effect processors
1543 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1544 controllers
1545 - global (sampler wide) volume can now be controlled at runtime
1546 - Implemented new, improved notification system
1547 - fixed compilation errors regarding OSX
1548 (patch by Toshi Nagata)
1549 - implemented instruments database
1550 - added support for escape sequences to the instruments database
1551 - added highly experimental support for on-the-fly instrument editing
1552 within the sampler's process (by using instrument editor plugins),
1553 you'll notice the new "Registered instrument editors:" message on
1554 startup, added a new LSCP command:
1555 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1556 to spawn a matching instrument editor for the instrument on the
1557 given sampler channel, the plugin path can be overridden at compile
1558 time with ./configure --enable-plugin-dir=/some/dir
1559 - added experimental code for synchronizing instrument editors hosted
1560 in the sampler's process to safely edit instruments while playing
1561 without a crash (hopefully) by either suspending single regions
1562 wherever possible or if unavoidable whole engine(s)
1563 - fixed several issues in fundamental "Thread" class: set scheduling
1564 policy and priority on thread level, set a minimum stack size for
1565 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1566 threads simply inherited properties of starting thread instead of
1567 setting their own policy and priority
1568 - minor fix in our automatic stack trace mechanism on crashes, the
1569 main process did not wait for the stack trace process to finish
1570 its output
1571 - fixed some minor memory leaks
1572 - reenabled assembly features support, at the moment only for
1573 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1574 - minor assembly fix in x86 features detection (don't use the PIC
1575 register, to avoid relocations in the text segment at runtime)
1576 - POSIX callback functions of Thread.h are hidden
1577
1578 * MIDI driver:
1579 - dispatch bank select (MSB and LSB) messages
1580
1581 * audio driver:
1582 - the ALSA audio output driver parameters now reflect the correct
1583 parameter value ranges for the respective selected sound card
1584 (patch by Till Wimmer, a bit fixed and extended)
1585
1586 * Gigasampler format engine:
1587 - if a filter is used and EG2 finishes before EG1, let the voice
1588 die when EG2 has finished (this fixes a problem with clicks and
1589 voice starvation for some gigs)
1590 - playback is no longer disabled during instrument loading
1591 - all notes playing on a channel that changes its instrument keep
1592 playing with the old instrument until they get a note off
1593 command
1594 - EG fix: a release value of zero could cause noises or crash
1595 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1596 - EG fine tuning: when attack is zero the EG starts at a level
1597 above max sustain level, which means that there is a decay phase
1598 even if sustain is 100%
1599 - more EG fixes: the level could sometimes go below zero and cause
1600 noises or crashes
1601 - minor fix of EGDecay (patch by Toshi Nagata)
1602 - fixed compiler error when --enable-override-filter-type was
1603 supplied to the configure script (fixes #46)
1604 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1605 instead of a fix value
1606 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1607 127 (solo mode) only kill voices if the respective mode really
1608 changed
1609
1610 * LSCP server:
1611 - fixed compile time error for old Bison versions
1612 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1613 - parser now supports extended ASCII character set
1614 (up to ASCII code 255, i.e. includes now umlauts and accents)
1615 - filename arguments in LSCP commands now allow to use escape
1616 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1617 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1618 code value like \xf2) (fixes bug #24)
1619 - the following LSCP commands now also support escape sequences for at
1620 least one of their text-based parameters (i.e. name, description):
1621 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1622 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1623 "SET DB_INSTRUMENT_DIRECTORY NAME",
1624 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1625 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1626 "FIND DB_INSTRUMENT_DIRECTORIES"
1627 - returns verbose syntax errors (line and column where syntax error
1628 occured, the unexpected character and the actually expected, possible
1629 character(s), the latter only if less than 5 possibilities)
1630 - made sure that LSCP syntax is not affected by gigedit locale
1631 settings
1632 - bugfix regarding strings parameter lists: all comma separated lists
1633 of strings were treated as being one string containing commas
1634 (fixes #57)
1635
1636 * Bug fixes:
1637 - fixed crash occurring on certain LSCP scripts (Bug 39)
1638 - another thread safety fix for lscp "load engine" and "set
1639 channel audio output device"
1640 - fixed a crash which occurs when reassigning the same engine
1641 on a sampler channel with connected MIDI device
1642 - fixed a crash which occurs when changing the number of ports of a MIDI
1643 device connected to a sampler channel to number less then or equal
1644 to the index of the port to which the sampler channel is connected.
1645 - The previous bindings were not been disconnected when altering
1646 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1647 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1648 - The active stream/voice count statistic was incorrect.
1649 - notification events were not been sent for some sampler
1650 channel changes
1651 - added default min and max values to restrict the number of allowed
1652 audio output channels and MIDI input ports
1653 - the connection to the PCM interface is now closed when destroying
1654 an audio output device
1655 - files with slash in their path or filename could not be loaded
1656
1657 * test cases:
1658 - updated and fixed (haven't been touched in a while)
1659
1660 Version 0.4.0 (24 November 2006)
1661
1662 * packaging changes:
1663 - changed deprecated copyright attribute to license; added ldconfig
1664 to post-(un)install steps; added devel package for liblinuxsampler;
1665 to linuxsampler.spec (RPM)
1666 - install necessary development header files for allowing 3rd party
1667 applications to link against liblinuxsampler
1668 - liblinuxsampler's API documentation can be generated with 'make docs'
1669 (Doxygen required)
1670 - added benchmark to automatically detect the best triangle LFO
1671 implementation (currently either an integer math solution or a
1672 di-harmonic approximation), automatic detection can be overriden
1673 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1674 configure script argument though (mandatory for cross-compilation)
1675 - do not automatically pick optimized gcc flags if the user already
1676 provided some on his own (as CXXFLAGS)
1677 - added compile time option to disable processing of All-Notes-Off MIDI
1678 messages
1679 - added compile time options to allow disabling the various audio and
1680 MIDI drivers
1681 - fixed automatic GCC CPU switch detection on PPC
1682 (patch by Ebrahim Mayat)
1683
1684 * Gigasampler format engine:
1685 - extensive synthesis optimization
1686 (reimplementation of EGs and LFO(s), removed synthesis parameter
1687 prerendering and the synthesis parameter matrix in general, splitting
1688 each audio fragment into subfragments now where each subfragment uses
1689 constant pitch and filter coefficients. The volume coefficient is
1690 linearly interpolated inside a subfragment, unless
1691 --disable-interpolate-volume is set.)
1692 - fine tuning of the EG modulation parameters
1693 - improved filter cutoff calculation by adding support for the
1694 following gig parameters: Cutoff freq (used when no cutoff
1695 controller is defined), Control invert, Minimum cutoff, Velocity
1696 curve and Velocity range. The keyboard tracking now scales
1697 cutoff frequency instead of resonance.
1698 - added support for gig parameter Resonance.
1699 - fixed bug in sysex handling (patch by Juan Linietsky)
1700 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1701 which can be overridden with --enable-global-attenuation
1702 - EG fixes: made the length of "attack hold" stage more
1703 accurate. Release stage can now start before attack stage
1704 ends. Cancel release didn't work when sustain was zero. Attack
1705 time now has a minimal value to prevent clicks.
1706 - fixed pitch changes larger than one octave
1707 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1708 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1709 all modes can be altered via standard GM messages, that is CC5 for
1710 altering portamento time, CC65 for enabling / disabling portamento
1711 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1712 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1713 parameter) and crossfade
1714 - added support for the "attenuation controller threshold" gig
1715 parameter
1716 - added smoothing of volume changes caused by control change
1717 messages
1718 - sample loop parameters are now taken from the DimensionRegion
1719 instead of the wave chunk
1720 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1721 not equal to a power of two
1722 - reimplementation of the filter algorithm. The new filter is more
1723 accurate and supports all gig filter types, including bandreject
1724 and lowpass turbo.
1725 - real support for 24 bit samples - samples are not truncated to
1726 16 bits anymore
1727 - support for aftertouch (channel pressure, not polyphonic
1728 aftertouch)
1729 - LFO1 behaviour fixed (dampening from max volume instead of
1730 amplifying from 0)
1731
1732 * LSCP server:
1733 - fixed application exit on broken pipe error (fixes bug #20)
1734 - fixed the notification messages delay due to lack of
1735 network activity (fixes bug #26)
1736 - fixed parser bug which occured on space(s) within device parameters
1737 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1738
1739 * audio driver:
1740 - added aRts audio output driver (by no means RT safe)
1741
1742 * MIDI driver:
1743 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1744 messages several times instead of once
1745 - API extension for MIDI drivers which already supply exact time stamps
1746 for events (i.e. for offline rendering based MIDI drivers)
1747 - added checks for bad MIDI data
1748
1749 * linuxsampler application:
1750 - show available sampler engine types on startup
1751
1752 * general changes:
1753 - support for muting sampler channels and solo mode of the same, two new
1754 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1755 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1756 introduced for this, the behavior is the same like on a mixer console
1757 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1758 --enable-process-muted-channels which can be used to enable the
1759 processing of muted channels.
1760 - support for sostenuto pedal
1761 - support for monitoring the total number of active voices
1762 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1763 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1764 - fixed some memory management errors
1765 - fixed some concurrency problems that could lead to crashes when
1766 LSCP commands were executed
1767 - fixed crash when instrument loading failed previously on the same
1768 sampler channel (fixes bug #36)
1769
1770 Version 0.3.3 (15 July 2005)
1771
1772 * packaging changes:
1773 - fixed compilation with gcc 4.0
1774
1775 * Gigasampler format engine:
1776 - LFO preprocessing was performed even though the respective LFO was
1777 disabled by the instrument patch (minor efficiency fix)
1778 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1779 for volume ramp downs in the same fragment (needed for current voice
1780 stealing implementation) then simply inform the user with a warning
1781 about possible click sounds and reduce the volume ramp down
1782 appropriately instead of cancelling the audio device connection
1783
1784 Version 0.3.2 (24 June 2005)
1785
1786 * packaging changes:
1787 - updated autotools build files to compile on OS X
1788 (conditional compilation of CoreMIDI and MidiShare drivers)
1789 - hand-crafted assembly optimization code can be disabled with
1790 './configure --disable-asm' (definitely not recommended)
1791 - fixed 'make dist' rule to include all necessary files
1792 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1793 (due to 'dist-bzip2' automake option)
1794
1795 * Gigasampler format engine:
1796 - support for the gig parameters for "release velocity response" curves
1797 - fine tuning of the EGADSR envelope
1798 - volume of release triggered samples now depends on note-on velocity,
1799 note length and gig parameter "release trigger decay" instead of
1800 note-off velocity.
1801 - revised voice stealing
1802 (fixes crash and endless loop caused by voice stealing)
1803 - don't reset scale tuning on instrument or audio output device change
1804 - handle key group conflicts right at the beginning of each fragment
1805 instead of when the respective voice is actually launched
1806 (fixes undefined behavior if stolen voices belonged to a key group -
1807 this case was followed by a "killed voice survived" error message)
1808 - fixed minor issue with null/silence samples
1809 (those stole voices even though they don't need a voice at all which
1810 resulted in "voice stealing didn't work out" messages)
1811 - don't reset volume, pan, pitch and MIDI controller values on
1812 instrument or audio output device change
1813
1814 * LSCP server:
1815 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1816 - fixed LSCP event "CHANNEL_INFO" notification
1817 (e.g. did not notify on volume changes or MIDI program change events)
1818
1819 * linuxsampler application:
1820 - added command line parameters --lscp-addr and --lscp-port to override
1821 default IP address and port of LSCP server
1822
1823 Version 0.3.1 (24 May 2005)
1824
1825 * initial release
