NKSP: Fixed crash with built-in functions returning an array.

* Calling built-in functions returning an array type was broken and
  caused a crash when built-in function's NULL (supposed to be array)
  result value was used by the script VM.

* Bumped version (2.1.1.svn37).

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
51 * Real-time instrument scripts:
52 - Added method ScriptVM::setExitResultEnabled() which allows to
53 explicitly enable the built-in exit() function to optionally accept
54 one function argument; the value of the passed exit() function
55 argument will then become available by calling
56 VMExecContext::exitResult() after script execution.
57 - 64 bit support for NKSP integer scripts variables (declare $foo).
58 - Variable names, function names and preprocessor condition names must start
59 with a regular character (a-z or A-Z); starting them with a digit or
60 underscore is not allowed.
61 - NKSP parser fix: equal comparison operator "=" and not equal comparison
62 operator "#" must only accept integer operands.
63 - NKSP language: Implemented support for standard units like Hertz, seconds,
64 Bel including support for metric unit prefixes; so one can now e.g.
65 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
66 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
67 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
68 - NKSP language: Introduced "final" operator "!" which is specifically
69 intended for synthesis parameter values to denote that the synthesis
70 parameter value is intended to be the "final" value for that synthesis
71 parameter that should explicitly be used by the engine and thus causing
72 the sampler engine to ignore all other modulation sources for the same
73 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
74 variable or formula with this new "!" operator the expression is marked as
75 being "final".
76 - NKSP script editor API: Added support for detecting standard unit tokens
77 and their potential metric prefix token.
78 - NKSP language: Added support for NKSP real number literals and
79 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
80 - NKSP language: Added support for NKSP real number (floating point) script
81 variables (declare ~foo).
82 - NKSP language: Added support for NKSP real number (floating point) array
83 script variables (declare ?foo[]).
84 - Built-in script function "message()" accepts now real number argument as
85 well.
86 - Added built-in script function "real_to_int()" and its short hand form
87 "int()" for casting from real number to integer in NKSP scripts.
88 - Added built-in script function "int_to_real()" and its short hand form
89 "real()" for casting from integer to real number in NKSP scripts.
90 - Allow built-in exit() function to potentially accept real number type
91 argument as well.
92 - Built-in script functions may have a different return type depending on
93 the arguments passed to the function.
94 - Built-in script function "abs()" optionally accepts and returns real
95 number.
96 - Built-in script functions "min()" and "max()" optionally accept real
97 number arguments and return real number as result in that case.
98 - NKSP VM API: Allow units and 'final'ness to be returned as result from
99 built-in functions (added methods VMFunction::returnUnitType() and
100 VMFunction::returnsFinal() for that purpose which must be implemented by
101 built-in function implementations).
102 - NKSP language: Allow metric unit prefixes of numeric scalar and array
103 variables to be changed freely at runtime (unlike unit types like Hz etc.
104 which are still sticky, parse-time features of variables which cannot be
105 changed at runtime for the intentional sake of determinism).
106 - NKSP language: 'final' values are prohibited for array variables for now
107 (attempt causes a parsers error).
108 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
109 conditions of runtime control structures like if(), while(), select()
110 (attempt causes a parser error).
111 - NKSP VM API: Allow built-in functions to perform their own, individual
112 parse time checks of arguments going to be passed to the function at
113 runtime (added method VMFunction::checkArgs() for that purpose).
114 - NKSP language: raise parser warning if only one operand of binary
115 operators (like logical 'or' comparison) contain a 'final' value (because
116 it would always yield in a 'final' result in such cases).
117 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
118 different metric unit prefixes, which will behave as expected (e.g.
119 result of expression '1000us < 2ms' is true).
120 - NKSP language: Allow adding values with different metric unit prefixes
121 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
122 - NKSP language: Allow subtracting values with different metric unit
123 prefixes (e.g. result of expression '1ms - 20us' is '980us').
124 - NKSP language: Allow multiplying with any metric unit prefixes
125 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
126 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
127 we don't have any considerable practical use for a term like '4s^2'
128 (hence any attempt multiplying two unit types still causes parser error).
129 - NKSP language: Allow dividing by any metric unit prefixes and allow
130 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
131 yields in unit free result '8'). So this is now a way to cast units away
132 e.g. for passing the result to other expressions, certain function calls
133 or variables which are not accepting any units (or that specific unit).
134 - NKSP language: integer arrays and real number arrays can now be converted
135 to strings (e.g. for dumping their content with message() calls for
136 script debugging purposes).
137 - NKSP language: expressions and variables with units are now correctly
138 casted to strings (e.g. with message() calls).
139 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
140 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
141 floating point tolerances into account.
142 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
143 VMScalarNumberExpr::evalCastReal().
144 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
145 'VMIntArrayExpr' and 'VMRealArrayExpr'.
146 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
147 unitFactor() (runtime) methods.
148 - Built-in function "exit()" supports now returning units and 'final'ness
149 for test cases.
150 - The following built-in functions support now units as well: "abs()",
151 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
152 "real_to_int()", "int()", "int_to_real()" and "real()".
153 - Built-in functions "array_equal()", "search()" and "sort()" support now
154 real number arrays (correctly) as well.
155 - Added individual parse time checks of arguments to be passed to built-in
156 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
157 "array_equal()" and "search()" specific for their individual purposes.
158 - NKSP VM refactoring: Renamed all methods, functions and classes matching
159 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
160 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
161 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
162 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
163 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
164 isScalarNumber() -> isNumber()).
165 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
166 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
167 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
168 as convenient methods for automatically converting values to expected
169 metric value basis.
170 - Built-in function "wait()" accepts now both integers and real numbers as
171 argument.
172 - NKSP VM API cleanup: Get rid of legacy method
173 VMFunction::argType(vmint iArg) which was already superseded by its new
174 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
175 - NKSP parser: if wrong argument type was passed to a built-in function and
176 that built-in function accepts more than one data type for the argument,
177 then show all supported data types as parser error message.
178 - Built-in function "play_note()" accepts now real numbers and seconds as
179 unit type as well for its 3rd and 4th function arguments.
180 - The following built-in functions accept now real numbers as well for their
181 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
182 "change_attack()", "change_decay()", "change_release()",
183 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
184 "change_cutoff_sustain()", "change_cutoff_release()",
185 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
186 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
187 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
188 - Fixed built-in function "change_play_pos()" not having accepted metric
189 prefixes at all.
190 - Fixed the following built-in functions having misinterpreted values given
191 with unit type (for their 2nd argument) as if they were relative values
192 (that is as if they were passed without a unit type): "change_attack()",
193 "change_decay()", "change_release()", "change_cutoff_attack()",
194 "change_cutoff_decay()", "change_cutoff_release()".
195 - Fixed the following built-in functions having applied completely wrong
196 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
197 respective EGs being their modulation sink assume uint data type with
198 value range 0..1000 instead of 0.0..1.0.
199 - Added individual parse-time checks of function arguments for the following
200 built-in functions: "play_note()", "note_off()", "set_event_mark()",
201 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
202 "change_decay()", "change_release()", "change_cutoff_attack()",
203 "change_cutoff_decay()", "change_cutoff_release()",
204 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
205 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
206 "change_pan_time()".
207 - Don't abort function call if unit type was used and at the same time
208 'final' operator was omitted for the primary value argument of the
209 following built-in functions: "change_cutoff()", "change_attack()",
210 "change_decay()", "change_release()", "change_cutoff_attack()",
211 "change_cutoff_decay()", "change_cutoff_release()",
212 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
213 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
214 "change_pan_time()", instead imply 'final'ness at runtime and raise an
215 appropriate parser warning at parse time.
216 - Added built-in real number functions "round()", "ceil()", "floor()",
217 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
218 "cos()", "tan()", "asin()", "acos()", "atan()".
219 - Added built-in script real number constant "~NI_MATH_PI".
220 - Added built-in script real number constant "~NI_MATH_E".
221 - NKSP language: Allow unary '+' operator.
222 - Added built-in script functions "msb()" and "lsb()".
223 - NKSP language: Added support for RPN event handler
224 ("on rpn ... end on" in instrument scripts).
225 - NKSP language: Added support for NRPN event handler
226 ("on nrpn ... end on" in instrument scripts).
227 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
228 may be read from the new RPN/NRPN script handlers to get the (N)RPN
229 parameter that had been changed and its new value.
230 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
231 which are identifying the new (N)RPN handlers as such at script runtime.
232 - Implemented built-in script function "set_rpn()".
233 - Implemented built-in script function "set_nrpn()".
234 - Fix: built-in functions returning an array type were broken and caused a
235 crash when the built-in function's (supposed to be array) result value was
236 used by the script VM.
237
238 * test cases:
239 - Fixed compiler errors in test cases.
240 - Updated README for how to compile & run test cases.
241 - Updated test case
242 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
243 expected behaviour of the Mutex class implementation (recursive
244 mutex type).
245 - Added test cases for NKSP core language aspects and core built-in
246 functions.
247 - Fixed thread tests segfaulting on Linux.
248 - NKSP: Added real number test cases for built-in functions exit(),
249 int_to_real(), real(), real_to_int() and int(), as well as for the
250 plus, minus and negate language operators.
251 - Added massive amount of NKSP test cases for standard measuring units and
252 'final' operator usage cases.
253 - Added NKSP test cases for (floating point tolerance aware) real number
254 equalness / unequalness comparison.
255 - Added NKSP int array and real array tests for value assignment and
256 initialization of arrays.
257 - Added NKSP test cases for built-in functions "round()", "ceil()",
258 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
259 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
260 - Added NKSP test cases for unary '+' operator.
261 - Added NKSP test cases for core built-in variables.
262
263 * GigaStudio/Gigasampler format engine:
264 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
265 behaviour for start_level_mid.
266 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
267 level (see discussion "GigaStudio LFO compatibility" on mailing list
268 from 2019-09-26 for details).
269 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
270 see discussion "GigaStudio LFO compatibility" on mailing list from
271 2019-09-26 for details).
272 - Format extension: Added support for different LFO wave forms (currently
273 either sine [default], triangle, saw or square).
274 - Format extension: Added support for LFO phase displacement (0��..360��).
275 - Format extension: Added support for flipping LFO polarity on LFO 3
276 (in the original gig format this was only available for LFO 1 and LFO 2).
277 - Format extension: Support for additional filter types:
278 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
279 bandreject 2-pole.
280
281 * SFZ format engine:
282 - Fixed support for regions with loccN/hiccN conditions on more than one
283 MIDI controller.
284
285 * Benchmarks:
286 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
287 algorithm (since result of 2nd run was not accumulated).
288 - Added benchmark for saw wave (benchmarks/saw.cpp).
289 - Added benchmark for sine wave (benchmarks/sine.cpp).
290 - Added benchmark for square wave (benchmarks/square.cpp).
291 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
292 which are large enough on modern systems.
293
294 Version 2.1.1 (27 Jul 2019)
295
296 * Real-time instrument scripts:
297 - Fixed behavior of built-in NKSP functions change_sustain(),
298 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
299 and change_cutoff_release().
300
301 * general changes:
302 - Only play release trigger samples on sustain pedal up if this behaviour
303 was explicitly requested by the instrument (otherwise only on note-off).
304 - Fixed compiler warnings.
305 - Fixed compilation error when cross-compiling to Mac.
306 - FX Sends: Provide more useful error messages on routing problems
307 (see bug #169).
308 - LSCP doc: Be more clear describing the two distinct approaches
309 of using external vs. internal effects (see bug #169).
310 - "optional" class: Fixed comparison operators.
311
312 * Gigasampler/GigaStudio format engine:
313 - Format extension: If requested by instrument then don't play release
314 trigger sample on note-off events.
315
316 * SFZ format engine:
317 - Fixed memory leak when releasing samples
318 (fixes bug #307, patch by Jacek Roszkowski)
319 - Fixed potential crash when a sample is shared by more than one region
320 (fixes bug #308, patch by Jacek Roszkowski).
321 - Opcode 'sample': Added support for built-in sample '*silence'
322 (fixes bug #310, patch by Jacek Roszkowski).
323
324 Version 2.1.0 (25 Nov 2017)
325
326 * SFZ format engine:
327 - added support for <global>, <master> and #define (patch by Alby M)
328 - Removed code duplication in SFZ file loading code.
329 - Added support for sfz extension opcode 'script' which may be used to
330 load real-time instrument script file (NKSP script language).
331 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
332 - Fixed unintended volume fade-in of voices under certain conditions.
333 - sfz parser: allow missing space between header and opcode
334
335 * Gigasampler/GigaStudio format engine:
336 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
337 cutoff settings.
338 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
339 all if an up-pitch of more than 40 semi tones was requested (I don't
340 think there is any stock gig sound that requires this behavior to
341 resemble its original sound).
342 - Added support for controlling whether the individual EGADSR stages may
343 be aborted (as LinuxSampler extension to the original GigaStudio 4
344 format).
345
346 * general changes:
347 - fixed printf type errors (mostly in debug messages)
348 - use unique_ptr instead of auto_ptr when building with C++11
349 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
350 allowing to sort data efficiently in real-time safe manner.
351 - RTList class: added methods for moving/inserting elements to arbitrary
352 position within a list.
353 - RTList class: added method fromPtr() for creating an Iterator object from
354 a raw element pointer.
355 - Attempt to partly fix resetting engine channels vs. resetting engine, an
356 overall cleanup of the Reset*(), ConnectAudioDevice(),
357 DisconnectAudioDevice() API methods would still be desirable though,
358 because the current situation is still inconsistent and error prone.
359 - Active voices are now internally grouped to "Note" objects, instead of
360 being directly assigned to a keyboard key. This allows more fine graded
361 processing of voices, which is i.e. required for certain instrument
362 script features.
363 - Fix: Release trigger voices were not spawned on sustain pedal up
364 (CC #64) events.
365 - Fix: Release trigger voices can now also distinguish correctly between
366 note-off and sustain pedal up events.
367 - All engines: Increased ramp speed of volume smoother and pan smoother
368 (while slow rate of crossfade smoother is preserved) to allow quick
369 volume and pan changes by instrument scripts for instance.
370 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
371 properly and thus were ignored for certain uses.
372 - Added new C++ API method
373 VirtualMidiDevice::SendChannelPressureToSampler().
374 - windows, 32-bit: fixed potential crashes by making sure the stack in
375 sub threads is 16-byte aligned
376 - fixed numerous compiler warnings
377 - Fixed invalid (note-on) event ID being assigned to new Note objects.
378 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
379 fixes potential undefined behavior.
380 - Fixed Note object leak when triggering notes on keys which did not
381 have a valid sample mapped (fixes bug #252).
382 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
383 - linuxsampler binary fix: option --create-instruments-db ignored
384 subsequent optional argument due to glibc's implementation oddity
385 which expects a "=" sign, but no space between them.
386
387 * packaging changes:
388 - removed unnecessary dependency to libuuid
389 (originated by libgig's usage of it)
390 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
391 auto detect whether it (sh/c)ould output its messages in color.
392 - Debian: Fixed packaging error about invalid "Source-Version"
393 substitution variable.
394 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
395 - Debian: Added build dependency to libsqlite3-dev for building
396 linuxsampler with instruments DB support.
397
398 * Real-time instrument scripts:
399 - Implemented scheduler for delayed MIDI events and for suspended scripts.
400 - Built-in script function "wait()": implemented support for function's
401 "duration-us" argument, thus scripts using this function are now
402 correctly resumed after the requested amount of microseconds.
403 - Built-in script function "play_note()": implemented support for
404 function's "duration-us" argument, thus notes triggered with this
405 argument are now correctly released after the requested amount of
406 microseconds.
407 - Fix: script events were not cleared when engine channel was reset,
408 potentially causing undefined behavior.
409 - Fixed crash which happened when trying to reference an undeclared
410 variable.
411 - Built-in script function "play_note()": Added support for passing
412 special value -1 for "duration-us" argument, which will cause the
413 triggered note to be released once the original note was released.
414 - Instrument script classes now exported with the liblinuxsampler C++ API.
415 - Added new API method ScriptVM::syntaxHighlighting() which provides
416 a convenient syntax highlighting backend for external instrument
417 script editor applications.
418 - Added new C++ API class "ScriptVMFactory".
419 - Extended parser issues to provide not only first line and first
420 column, but also last line and last column of issue (thus marking
421 the precise span of the issue within the source code).
422 - Reload script automatically after being modified by an instrument
423 editor.
424 - NKSP language grammar correction: allow empty event handler bodies
425 like "on note end on".

434 "event_status()" function.
435 - NKSP language: Added support for bitwise operators ".or.", ".and."
436 and ".not.".
437 - NKSP language scanner: Fixed IDs matching to require at least one
438 character (i.e. when matching function names or variable names).
439 - NKSP language scanner: disabled unusued rules.
440 - Fixed behavior of play_note() and note_off() functions which must
441 be distinguished engine internally from "real" MIDI note on/off
442 events in order to avoid misbehaviors like hanging notes.
443 - Implemented built-in script variable "$KSP_TIMER".

448 - Implemented built-in script function "dec()".
449 - NKSP language fix: division expressions were evaluated too often.
450 - NKSP language fix: string concatenation operator was right
451 associative instead of left (to right).
452 - NKSP language correction: allow empty statements in entire language
453 (i.e. "if end if").

468 - Fixed all change_*() built-in script functions to apply their
469 synthesis parameter changes immediately in case the respective note
470 was triggered at the same time, instead of scheduling the parameter
471 change, especially because it would cause some parameter types's
472 changes either to be ramped (i.e. change_vol()) or other types even
473 to have not effect at all (i.e. change_attack()).
474 - Implemented built-in script function "sh_left()".
475 - Implemented built-in script function "sh_right()".
476 - Implemented built-in script function "min()".
477 - Implemented built-in script function "max()".

479 was loaded.
480 - NKSP built-in wait() script function: abort script execution if
481 a negative or zero wait time was passed as argument (since this is
482 a common indication of a bug either of the script or even of the
483 engine, which could lead to RT instability or even worse).
484 - ScriptVM: Implemented automatic suspension of RT safety
485 threatening scripts.

498 - Implemented built-in script function "fade_out()".
499 - Fixed acceptance of wrong data type of parameters passed to built-in
500 script functions "change_vol()", "change_tune()", "change_pan()",
501 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
502 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

504 - Added built-in script function "get_event_par()" and implemented some
505 of its possible parameter selections.
506 - Added built-in script function "set_event_par()" and implemented some
507 of its possible parameter selections.
508 - Fixed a bunch of scheduler time related bugs.
509 - Fixed polyphonic variables not being reset to zero after usage.
510 - Built-in "ignore_event()" function: argument is now optional, like with
511 built-in function "ignore_controller()".
512 - Implemented built-in script function "change_velo()".
513 - Implemented built-in script function "change_note()".
514 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
515 intuitive behavior if used in combination with "change_vol_time()" or
516 "change_tune_time()" respectively: now tuning/volume changes are only
517 assigned (without delay) immediately to a new note if the respective
518 timing function has not been called before, otherwise the volume/tuning
519 changes are automatically faded (before, only the event's time stamp was
520 relevant).
521 - Implemented built-in script function "array_equal()".
522 - Implemented built-in script function "search()".
523 - Implemented built-in script function "sort()".
524 - NKSP Fix: Never suspend "init" event handlers.

526 available for gig format engine).
527 - Added built-in script constant "$NKSP_LINEAR".
528 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
529 - Implemented built-in script function "change_vol_curve()".
530 - Implemented built-in script function "change_tune_curve()".
531 - built-in "play_note()" function now supports a sample playback start
532 offset with argument 3, where special value -1 means to use the regular
533 sample offset as defined by the instrument file.
534 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
535 - Built-in variable $EVENT_NOTE is now a read-only variable.
536 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
537 - built-in "play_note()" function now accepts -2 for its fourth argument
538 (note duration) which means the life time of the note shall be sticked
539 to the requested note number of argument 1.
540 - Fix: built-in "play_note()" function now returns 0 as result value if
541 -1 was passed for its fourth argument (note duration) and the respective
542 parent note is already gone.
543 - Implemented built-in script function "change_play_pos()".
544 - NKSP language: Added support for user declared const array variables.
545 - NKSP language: Raise parser warning if array variable is accessed with
546 an index that exceeds the array's size.
547 - NKSP language fix: Unknown characters were not handled correctly.
548 - NKSP language: Added support for "synchronized .. end synchronized"
549 code blocks.
550 - Implemented built-in script function "abort()" which allows to abort
551 another script handler by passing its callback ID.
552 - Fixed potential memory access bug and potential undefined behavior of
553 "init" event handlers.
554 - Print a time stamp along to each call of built-in function "message()".
555 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
556 to retrieve all code blocks filtered out by the preprocessor.

563 - Added built-in constant $CALLBACK_STATUS_QUEUE.
564 - Added built-in constant $CALLBACK_STATUS_RUNNING.
565 - Removed max. value limitation of built-in functions "change_attack()",
566 "change_decay()" and "change_release()" to i.e. allow passing 2000000
567 for doubling the respective time.
568 - NKSP script editor syntax highlighting API: Fixed app termination due
569 to a lexer start condition stack underrun.
570 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
571 USE_CODE_IF_NOT() preprocessor statements.
572 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
573 can be set to disable all subsequent built-in "message()" function calls
574 on preprocessor level.
575 - Implemented built-in script function "change_sustain()".
576 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
577 to avoid the editor app to crash on ill-formed text input.

589 undefined behavior.
590 - Cleanup of instruments DB file creation and opening code.

592 is now optional, if it is missing, then a default location is used.
593 - Added support for scanning SFZ (.sfz) files.
594 - Added support for scanning Sound Font (.sf2) files.
595 - Fixed undefined DB transaction behavior.

609 - minor Makefile fix for building lscpparser when build and source
610 directories are separate
611 - Mac OS X: made it possible to specify plugin installation dir to
612 configure
613 - Mac OS X: Makefile fix for the install-strip target
614 - fixed compilation with gcc 4.7
615 - fixed configure script error with old autoconf versions
616 - lsatomic.h: use gcc provided atomic functions if building with
617 gcc 4.7 and C++11
618 - modernized configure script
619 - fixed linkage error when building with
620 LDFLAGS="-Wl,--no-undefined" (#190)
621 - fixed compilation with Clang 3.2
622 - removed usage of deprecated Automake variable INCLUDES
623 - fixed building with C++11
624 - build fix: ChangeFlagRelaxed.h was missing in makefile

626 makefiles
627 - fix for building with bison 3.0 (#202)
628 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
629 on the process's main thread
630 - fixed build error on newer MinGW
631 - support building with older jack versions

635 in order to get rid of warnings from automake 1.14
636
637 * general changes:
638 - Refactoring: moved the independent code from
639 the Gigasampler format engine to base classes
640 - command line option '--profile' is currently disabled, since the
641 respective profiling code is currently broken
642 - Introduced support for optional environment variable
643 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
644 where the sampler shall look for instrument editor plugins
645 (patch by Luis Garrido, slightly modified).
646 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
647 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
648 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
649 note (in this implementation of the sampler its simply hard routed to
650 the 1st effect send of the sampler channel, no matter what the actual
651 effect type is)
652 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
653 note (in this implementation of the sampler its simply hard routed to
654 the 2nd effect send of the sampler channel, no matter what the actual
655 effect type is)
656 - implemented support for internal LADSPA effects
657 - raised limit of program change queue from 100 to 512
658 (as suggested by Alex Stone)
659 - implemented sine LFO, pulse LFO and saw LFO
660 - experimental support for per voice equalization
661 - added command line option --exec-after-init
662 - Introduced new C++ API method:
663 EngineChannel::InstrumentFileName(int index)
664 allowing to retrieve the whole list of files used for the loaded
665 instrument on an engine channel (a.k.a. part). Some GigaStudio
666 instruments for example are splitted over several files like
667 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
668 - Added new C++ API method Sampler::GetGlobalMaxVoices().
669 - Added new C++ API method Sampler::GetGlobalMaxStreams().
670 - Added new C++ API method Sampler::SetGlobalMaxVoices().
671 - Added new C++ API method Sampler::SetGlobalMaxStreams().
672 - Various "const" and "restrict" optimizations.
673 - all engines: add pan CC value to instrument pan parameter before
674 applying panning, instead of using two separate pan functions in
675 series (#182)
676 - added a lock guard class for exception safe mutex handling and
677 used it everywhere appropriate
678 - Immediately apply scale tuning changes to active voices.
679 - Exposed scale tuning to C++ API (along to the already existing standard
680 SysEx way).
681 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
682 and broken for ppc64. (Seq_cst loads and stores are actually not
683 used in LS, so the bug wasn't noticable.)
684 - lsatomic.h: added ARMv7 support
685 - Added support for multiple MIDI input ports per sampler channel (and
686 added various new C++ methods for this new feature / design change, old
687 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
688 as deprecated but are still there and should provide full behavior
689 backward compatibility).
690 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
691 unsafe and caused compilation error with clang 2.x).
692 - Bugfix: only process the latest MIDI program change event.
693 - Introducing the LSCP shell, which provides convenient control of the
694 sampler from the command line by providing LSCP aware features.
695 - VirtualMidiDevice: Added support for program change.
696 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
697 - VirtualMidiDevice: Added support for pitch bend.
698 - Aftertouch: extended API to explicitly handle channel pressure and
699 polyphonic key pressure events (so far polyphonic pressure was not
700 supported at all, and channel pressure was rerouted as CC128 but not
701 used so far).
702 - Added initial support for real-time instrument scripts. The script VM
703 code is shared by all sampler engine implemementations, however only the
704 gig file format currently provides support for storing instrument scripts
705 (as LinuxSampler extension to the original GigaStudio 4 format).
706
707 * Gigasampler format engine:
708 - implemented the "round robin keyboard" dimension
709 - fixed round robin and random dimensions for cases when number of
710 dimension zones is not a power of two

712 key
713 - bugfix: pitch LFO controller "internal+aftertouch" was broken
714 - bugfix: filter keyboard tracking was broken
715 - filter performance fix (an unnecessary copy was made of the
716 filter parameters in each sub fragment)
717 - handle special case when pan parameter in gig file has max or
718 min value
719 - Exclusive Groups: don't ever stop voices of the same note,
720 doesn't sound naturally with a drumkit
721 - fixed EG1 modulation when attack or release is zero
722 - Fixed support for 'aftertouch' attenuation controller.
723 - Fixed crash that happened with velocity split sounds under certain
724 conditions (see also previous commit on libgig).
725 - fixed behaviour of filter LFO
726
727 * SFZ format engine:

757 - added support for loop_mode=one_shot
758 - fixed playback of 16 bit wav files on big endian CPUs
759 - added support for Ogg Vorbis sample files
760 - use loop markers from sample file if loop_start and loop_end are
761 not set in sfz file
762 - implemeted filters. Filter types: lowpass, bandpass, bandreject
763 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
764 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
765 cutoff_cc, cutoff_chanaft.
766 - bugfix: zero ampeg_sustain didn't work

953 to them a la JACK, via the usual sampler APIs
954 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
955 the driver will automatically connect to other CoreMIDI clients' ports
956 (e.g. external MIDI devices being attached to the Mac)
957 - added support for MIDI note on velocity filter
958 - CoreMIDI: fixed memory deallocation error
959 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
960 virtual keyboards in frontends / instrument editors being stuck.
961 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

1030 - Added support for moving cursor left/right with arrow keys.
1031 - Added support for built-in LSCP reference documentation, which will
1032 automatically show the relevant LSCP reference section on screen as soon

1082 - Pass/preserve polyphonic variable data from respective "note" event
1083 handler to "release" event handler.
1084 - Fixed crash when using built-in script function "by_marks()".
1085

1090 channel to a different engine type
1091 - fixed crash when deleting a sampler channel or changing engine
1092 type while an instrument load was in progress
1093 - bugfix: playing a note while changing the instrument could cause
1094 a crash, or give "Handing back unknown region" error messages
1095 - bugfix: calling SET VOICES (which Fantasia does on start and
1096 refresh) could cause instruments to be unloaded
1097 - Mac OS X: fixed name collision of enum in EffectControl and
1098 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1099 - Mac OS X: fixed hanging threads

1106 took the full preloading time and on 1st program change the respective
1107 instrument was completely reloaded again.
1108 - fixed handling of rapid bank select and program change messages
1109 sent to the same sampler channel (patch from the Open Octave
1110 project, slightly adjusted)

1129 crashes and noise on such transitions).
1130 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1131 (fixes #208)
1132 - Fixed bug in LSCP grammar definition which caused a statement like
1133 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1134 practically irrelevant, however it caused problems with the new LSCP
1135 shell's auto completion feature).
1136 - Fixed MIDI program change messages being ignored if quickly executed
1137 after each other (fixes #231).
1138
1139 Version 1.0.0 (31 July 2009)
1140
1141 * packaging changes:
1142 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1143 causing e.g. the libgig test to fail when
1144 "./configure --disable-jack-driver" was used
1145 (patch by Alexis Ballier)
1146 - fixed compilation with gcc 4.3
1147 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1154 directory of liblinuxsampler dll (look in the same directory and one
1155 directory above)
1156 - configure script fix: removed unconditional use of SSE
1157 - fixed building with sqlite installed in a non-standard directory
1158 - when cross-compiling, don't try to create instruments.db
1159 - fix for new mingw-w64 version, which has usleep
1160
1161 * general changes:
1162 - bugfix: on some POSIX systems instrument editor plugins refused to
1163 load as we used a non-portable Linux specific struct field
1164 (fixes bug #70, patch by Ronald Baljeu)
1165 - fixed endless loop which occured when loading an instrument editor
1166 plugin DLL on Windows systems failed
1167 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1168 - optimized the SynchronizedConfig class so it doesn't wait
1169 unnecessarily long after an update
1170 - added support for notifying instrument editors on note-on / note-off
1171 events (e.g. to highlight the pressed keys on the virtual keyboard
1172 of gigedit)
1173 - added support for triggering notes by instrument editors (see above)
1174 - be verbose on DLL load errors (on Linux)
1175 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1176 is only used by very few systems, most pick the int math
1177 implementation, which is usually faster)
1178 - fixes for audio drivers with varying buffer sizes
1179 - experimental support for running LinuxSampler as a DSSI, LV2 and
1180 VST plugin
1181 - notification events for stream/voice count statistics are now sent
1182 only when there are actual changes

1184 multi-core and multi-cpu systems
1185 - maximum voices and disk streams can now be altered at runtime
1186 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1187 - automatic stacktrace mechanism is now turned off by default and can
1188 be switched on by command line option "--stacktrace" (the automatic
1189 stacktrace mechanism seems to be broken on most systems at the moment)
1190 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1191 a pointer to the launched InstrumentEditor object
1192 - added optional 3rd party user data parameter for following
1193 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1194 InstrumentEditor::Launch(),
1195 InstrumentManager::LaunchInstrumentEditor()
1196 - theoretical fix: made SynchronizedConfig follow C++0x memory
1197 model more strictly
1198 - fixes for using large audio device buffers
1199 - Windows: add the installation directory to the DLL search path
1200 when loading an editor plugin (solves problems with VST and
1201 gigedit on systems with other GTK versions installed)
1202 - updated linuxsampler man page
1203
1204 * audio driver:
1205 - removed the nonsense audio channel constraint (which was hard coded to
1206 max. 100 audio channels) for most audio drivers
1207 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1208 opposed to the LSCP specs
1209 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1210 reflected the wrong value
1211 - fixed a memory management bug in ASIO driver
1212 - Makefile fix: JACK_CFLAGS wasn't used
1213 - JACK: use jack_client_open instead of the deprecated
1214 jack_client_new
1215 - added (experimental) CoreAudio driver
1216 - applied old fixes to the ASIO driver that were included in the
1217 previous binary release but accidentally never committed to CVS

1220 win64)
1221 - VST: added support for sample rate and buffer size changes
1222 - VST: close editor (Fantasia) when the VST is removed
1223 - VST: avoid opening Fantasia more than once for each VST instance
1224 - VST: export main function as "main" on Linux too (fix for
1225 energyXT)
1226 - VST: changed number of output channels from one stereo to 16
1227 stereo
1228 - added channel routing, fxsends and midi maps to the settings
1229 stored in the plugin state
1230 - performance optimization of AudioChannel::MixTo() and
1231 AudioChannel::CopyTo() methods using GCC vector exensions
1232 (if available)
1233 - ASIO fixes: avoid initializing the device twice, avoid throwing
1234 exception when getting parameters from a disconnected device
1235
1236 * MIDI driver:
1237 - added JACK MIDI driver
1238 - dispatch bank select as ordinary CC as well, the user might seriously
1239 want to (mis)use it for some purpose ("fixed" in all current MIDI
1240 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1241 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1242 CoreMidi or AU
1243 - fixed mingw-w64 compilation error in MME driver
1244 - made program change handling in MIDI thread real-time safe by
1245 moving the logic to a non-RT thread

1252 - Implemented option for adding instruments in separate directories
1253 in the instruments database
1254 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1255 - work-around for missing fnmatch function on Windows to make
1256 instrument database compilable
1257 - added instrument database support on Windows
1258 works with both standalone mode and VST plugin.
1259 the instruments DB file is located in
1260 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1261 databases for each windows user
1262 if no DB is present it automatically creates the .linuxsampler subdir
1263 and then creates an empty DB
1264 - fixed recursive import, which was broken on Windows
1265
1266 * Gigasampler format engine:
1267 - fixed a memory leak that could happen when a channel was deleted
1268 while notes were playing
1269 - made it possible to load an instrument even if the audio thread
1270 isn't running
1271 - added partial support for the "Controller Triggered" MIDI rule,
1272 enough for piano gigs with pedal noise samples
1273 - minor fix: only mark FX sends as being modified if really the
1274 respective FX send MIDI controller was used
1275 - added support for GM global device volume SysEx message
1276 (can be selected at compile time to either apply globally to the
1277 whole sampler [default] or only to the sampler channels that are
1278 connected to the respective MIDI input port the SysEx message arrived
1279 on)
1280 - bugfix: notes triggered at position 0 in the audio buffer were
1281 sometimes wrongly killed in the same buffer, causing no sound to
1282 be played
1283 - added support for chromatic / drumkit mode Roland GS Sysex message
1284 which is usally used to switch a part between chromatic sounds and
1285 drumkit sounds (as opposed to their common default setting of MIDI
1286 part 10 being a drumkit part and all other ones chromatic parts), in
1287 LS however one can switch between the first 16 MIDI instrument maps
1288 defined for the sampler
1289 - made it possible to create multiple sample channels even if the
1290 audio thread isn't running
1291 - fixed crash when removing channel with active voices (#116)
1292 - bugfix: on sample reference changes (instrument editor), only
1293 un-cache the respective sample if it's really not used by any
1294 sampler engine anymore
1295 - re-cache samples in case they were changed by an instrument editor,
1296 e.g. when a sample was added while playing (#82)
1297 - fixed hanging notes which occured when note-off event had the exact
1298 same time stamp as the voice's note-on event and occured both in the
1299 same audio fragment cycle (fixes bug #112)
1300 - added support for the "fine tune" and "pitch bend range"
1301 instrument-level gig parameters
1302 - fixed minor artifacts in pitch bend handling
1303 - added support for GS Reset SysEx message
1304 - allow gig files to use unlimited downward pitch shifting
1305 - added a limit check for upward pitch shifting
1306 - bugfix: sometimes, when playing a note twice fast, the second
1307 note was silent
1308 - fixed crash happening when a pitch bend event arrived at the
1309 same time a new instrument was loading
1310
1311 * LSCP server:
1312 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1313 react on MIDI data arriving on certain sampler channels (so far only
1314 Note-On and Note-Off events are sent via this LSCP event)
1315 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1316 react on MIDI data arriving on certain MIDI input devices (so far only
1317 Note-On and Note-Off events are sent via this LSCP event)
1318 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1319 SET DB_INSTRUMENT FILE_PATH
1320 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1321 frontends to send MIDI messages to specific sampler channel
1322 - added two additional fields to GET FILE INSTRUMENT INFO command -
1323 KEY_BINDINGS and KEYSWITCH_BINDINGS
1324 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1325 was incorrect
1326 - Optimized the retrieval of the MIDI instrument mappings
1327 - added new LSCP command "SET VOICES" to globally alter the maximum
1328 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1329 be triggered respectively
1330 - added new LSCP command "SET STREAMS" to globally alter the maximum
1331 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1332 which will be triggered respectively
1333 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1334 a gigedit file dialog is opened)
1335 - close all connections when LSCPServer is deleted
1336 - hard close of all sockets on exit
1337 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1338 driver
1339
1340 * Bug fixes:
1341 - fixed a crash which occurs when removing a sampler channel waiting
1342 to start instrument loading after another channel
1343 - fixed a crash which occurs when removing a sampler channel with
1344 instrument loading in progress (bug #113)
1345 - fixed termination caused by uncaught exception when adding MIDI
1346 instrument with PERSISTENT load mode
1347 - fixed possible iterator invalidations when resetting the sampler
1348 - fixed memory leaks when issuing the following LSCP commands:
1349 GET AUDIO_OUTPUT_DRIVER INFO
1350 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1351 GET MIDI_INPUT_DRIVER INFO
1352 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1353 - fixed possible compilation error when sqlite is not present
1354 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1355 - fixed crash when changing the audio output device of a sampler
1356 channel with loaded instrument and start playing notes
1357 - fixed endless loop in Engine::SuspendAll() (bug #120)
1358 - fixed a low-level atomic load function that was broken on 64-bit
1359 PowerPC, which probably could cause crashes on that platform
1360 - fixed a memory management error which could cause a crash when a
1361 plugin was unloaded
1362 - bugfix: two private structs had the same name, which could cause
1363 problems if the linker chose the wrong constructor
1364 - fixed low-level ConditionServer usage bug that caused lockups on
1365 Windows
1366
1367
1368 Version 0.5.1 (6 December 2007)
1369
1370 * packaging changes:
1371 - added autoconf checks for pthread library
1372 - added autoconf check for pthread bug found on certain NPTL-enabled
1373 glibc versions (see Gentoo bug report #194076)
1374 - added autoconf checks for MS Windows
1375
1376 * general changes:
1377 - bugfix: the thread used by an editor plugin didn't die when the
1378 editor closed
1379 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1380 out all the space. operator--() did not apply size_mask after
1381 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1382 order to avoid problems with the _NonVolatileReader functions.
1383 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1384 GetWriteSpace(). Since this function is currently only used in
1385 the stream's qsort() compare function, it didn't trigger any
1386 bugs.
1387 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1388 24bit mode too. Faster method to read 24bit words on little
1389 endian machines (x86): replaced 3 byte reads + shifts with a 1
1390 unaligned 32bit read and shift
1391 - experimental support for MS Windows (MIDI input via MME, AUDIO
1392 output via ASIO)
1393 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1394 - support for monitoring the total number of active disk streams
1395 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1396 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1397
1398 * AUDIO driver:
1399 - added Windows ASIO low latency audio driver
1400
1401 * MIDI driver:
1402 - added MME Windows MIDI driver
1403
1404 * LSCP server:
1405 - added support for Windows style path / filenames, however with
1406 forward slash path separators instead of backslash
1407 (i.e. "C:/foo/bar.gig")
1408 - allow naughty liblscp to send non-string device parameters within
1409 apostrophes as well
1410 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1411 "LIST FILE INSTRUMENTS <file>" and
1412 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1413 about an arbitrary instrument file on the system where the sampler is
1414 running on
1415
1416 Version 0.5.0 (15 October 2007)
1417
1418 * packaging changes:
1419 - config.h is not going to be installed along with liblinuxsampler's
1420 API header files anymore
1421 - only the API relevant header (and source) files will be exported to
1422 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1423 - added completely new XCode project files for Mac OSX which is now
1424 capable to execute our autoconf environment, thus no need anymore
1425 to maintain the compile time configuration file (osx/version.h) for
1426 OSX manually (patch by Toshi Nagata)
1427 - fixed buggy boolean --enable-foo / --disable-foo configure script
1428 parameters
1429 - global.h now only covers global definitions that are needed for the
1430 C++ API header files, all implementation internal global definitions
1431 are now in global_private.h
1432 - atomic.h is not exposed to the C++ API anymore
1433 - no need to include config.h anymore for using LS's API header files
1434 - fixed warnings in API doc generation
1435
1436 * general changes:
1437 - replaced the old, confusing MIDI program change mechanism by a
1438 flexible MIDI instrument mapper which allows to map arbitrary
1439 (MIDI bank, MIDI program) pairs with arbitrary
1440 (engine type, instrument file, file index) triplets which will be
1441 loaded on the respective channel when such MIDI program change
1442 messages arrive, beside that, each entry allows to define a life-time
1443 strategy for the instrument, so the user can define whether the
1444 instrument should i.e. be permanently loaded (to be able to switch
1445 quickly among sounds) or i.e. loaded just on demand when the
1446 respective program change arrives (to safe RAM space), as well as a
1447 global volume factor for each entry, so the user can adjust the volume
1448 dynamic of his mapped instrument collection without having to modify
1449 the instrument files, also one can manage arbitrary amount of such
1450 MIDI instrument maps and assign each sampler channel individually
1451 a certain map, so that i.e. separation of normal instruments and
1452 drumkits is possible
1453 - new notification events for tracking changes to audio/MIDI devices,
1454 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1455 - sampler was limited to load max. 200 instruments in the background
1456 due to a constant size RingBuffer FIFO which is now replaced by a
1457 dynamic (unlimited) size std::list FIFO
1458 - added FX sends, these allow to route audio signals to arbitrary audio
1459 output channels for being processed by external effect processors
1460 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1461 controllers
1462 - global (sampler wide) volume can now be controlled at runtime
1463 - Implemented new, improved notification system
1464 - fixed compilation errors regarding OSX
1465 (patch by Toshi Nagata)
1466 - implemented instruments database
1467 - added support for escape sequences to the instruments database
1468 - added highly experimental support for on-the-fly instrument editing
1469 within the sampler's process (by using instrument editor plugins),
1470 you'll notice the new "Registered instrument editors:" message on
1471 startup, added a new LSCP command:
1472 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1473 to spawn a matching instrument editor for the instrument on the
1474 given sampler channel, the plugin path can be overridden at compile
1475 time with ./configure --enable-plugin-dir=/some/dir
1476 - added experimental code for synchronizing instrument editors hosted
1477 in the sampler's process to safely edit instruments while playing
1478 without a crash (hopefully) by either suspending single regions
1479 wherever possible or if unavoidable whole engine(s)
1480 - fixed several issues in fundamental "Thread" class: set scheduling
1481 policy and priority on thread level, set a minimum stack size for
1482 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1483 threads simply inherited properties of starting thread instead of
1484 setting their own policy and priority
1485 - minor fix in our automatic stack trace mechanism on crashes, the
1486 main process did not wait for the stack trace process to finish
1487 its output
1488 - fixed some minor memory leaks
1489 - reenabled assembly features support, at the moment only for
1490 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1491 - minor assembly fix in x86 features detection (don't use the PIC
1492 register, to avoid relocations in the text segment at runtime)
1493 - POSIX callback functions of Thread.h are hidden
1494
1495 * MIDI driver:
1496 - dispatch bank select (MSB and LSB) messages
1497
1498 * audio driver:
1499 - the ALSA audio output driver parameters now reflect the correct
1500 parameter value ranges for the respective selected sound card
1501 (patch by Till Wimmer, a bit fixed and extended)
1502
1503 * Gigasampler format engine:
1504 - if a filter is used and EG2 finishes before EG1, let the voice
1505 die when EG2 has finished (this fixes a problem with clicks and
1506 voice starvation for some gigs)
1507 - playback is no longer disabled during instrument loading
1508 - all notes playing on a channel that changes its instrument keep
1509 playing with the old instrument until they get a note off
1510 command
1511 - EG fix: a release value of zero could cause noises or crash
1512 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1513 - EG fine tuning: when attack is zero the EG starts at a level
1514 above max sustain level, which means that there is a decay phase
1515 even if sustain is 100%
1516 - more EG fixes: the level could sometimes go below zero and cause
1517 noises or crashes
1518 - minor fix of EGDecay (patch by Toshi Nagata)
1519 - fixed compiler error when --enable-override-filter-type was
1520 supplied to the configure script (fixes #46)
1521 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1522 instead of a fix value
1523 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1524 127 (solo mode) only kill voices if the respective mode really
1525 changed
1526
1527 * LSCP server:
1528 - fixed compile time error for old Bison versions
1529 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1530 - parser now supports extended ASCII character set
1531 (up to ASCII code 255, i.e. includes now umlauts and accents)
1532 - filename arguments in LSCP commands now allow to use escape
1533 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1534 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1535 code value like \xf2) (fixes bug #24)
1536 - the following LSCP commands now also support escape sequences for at
1537 least one of their text-based parameters (i.e. name, description):
1538 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1539 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1540 "SET DB_INSTRUMENT_DIRECTORY NAME",
1541 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1542 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1543 "FIND DB_INSTRUMENT_DIRECTORIES"
1544 - returns verbose syntax errors (line and column where syntax error
1545 occured, the unexpected character and the actually expected, possible
1546 character(s), the latter only if less than 5 possibilities)
1547 - made sure that LSCP syntax is not affected by gigedit locale
1548 settings
1549 - bugfix regarding strings parameter lists: all comma separated lists
1550 of strings were treated as being one string containing commas
1551 (fixes #57)
1552
1553 * Bug fixes:
1554 - fixed crash occurring on certain LSCP scripts (Bug 39)
1555 - another thread safety fix for lscp "load engine" and "set
1556 channel audio output device"
1557 - fixed a crash which occurs when reassigning the same engine
1558 on a sampler channel with connected MIDI device
1559 - fixed a crash which occurs when changing the number of ports of a MIDI
1560 device connected to a sampler channel to number less then or equal
1561 to the index of the port to which the sampler channel is connected.
1562 - The previous bindings were not been disconnected when altering
1563 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1564 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1565 - The active stream/voice count statistic was incorrect.
1566 - notification events were not been sent for some sampler
1567 channel changes
1568 - added default min and max values to restrict the number of allowed
1569 audio output channels and MIDI input ports
1570 - the connection to the PCM interface is now closed when destroying
1571 an audio output device
1572 - files with slash in their path or filename could not be loaded
1573
1574 * test cases:
1575 - updated and fixed (haven't been touched in a while)
1576
1577 Version 0.4.0 (24 November 2006)
1578
1579 * packaging changes:
1580 - changed deprecated copyright attribute to license; added ldconfig
1581 to post-(un)install steps; added devel package for liblinuxsampler;
1582 to linuxsampler.spec (RPM)
1583 - install necessary development header files for allowing 3rd party
1584 applications to link against liblinuxsampler
1585 - liblinuxsampler's API documentation can be generated with 'make docs'
1586 (Doxygen required)
1587 - added benchmark to automatically detect the best triangle LFO
1588 implementation (currently either an integer math solution or a
1589 di-harmonic approximation), automatic detection can be overriden
1590 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1591 configure script argument though (mandatory for cross-compilation)
1592 - do not automatically pick optimized gcc flags if the user already
1593 provided some on his own (as CXXFLAGS)
1594 - added compile time option to disable processing of All-Notes-Off MIDI
1595 messages
1596 - added compile time options to allow disabling the various audio and
1597 MIDI drivers
1598 - fixed automatic GCC CPU switch detection on PPC
1599 (patch by Ebrahim Mayat)
1600
1601 * Gigasampler format engine:
1602 - extensive synthesis optimization
1603 (reimplementation of EGs and LFO(s), removed synthesis parameter
1604 prerendering and the synthesis parameter matrix in general, splitting
1605 each audio fragment into subfragments now where each subfragment uses
1606 constant pitch and filter coefficients. The volume coefficient is
1607 linearly interpolated inside a subfragment, unless
1608 --disable-interpolate-volume is set.)
1609 - fine tuning of the EG modulation parameters
1610 - improved filter cutoff calculation by adding support for the
1611 following gig parameters: Cutoff freq (used when no cutoff
1612 controller is defined), Control invert, Minimum cutoff, Velocity
1613 curve and Velocity range. The keyboard tracking now scales
1614 cutoff frequency instead of resonance.
1615 - added support for gig parameter Resonance.
1616 - fixed bug in sysex handling (patch by Juan Linietsky)
1617 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1618 which can be overridden with --enable-global-attenuation
1619 - EG fixes: made the length of "attack hold" stage more
1620 accurate. Release stage can now start before attack stage
1621 ends. Cancel release didn't work when sustain was zero. Attack
1622 time now has a minimal value to prevent clicks.
1623 - fixed pitch changes larger than one octave
1624 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1625 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1626 all modes can be altered via standard GM messages, that is CC5 for
1627 altering portamento time, CC65 for enabling / disabling portamento
1628 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1629 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1630 parameter) and crossfade
1631 - added support for the "attenuation controller threshold" gig
1632 parameter
1633 - added smoothing of volume changes caused by control change
1634 messages
1635 - sample loop parameters are now taken from the DimensionRegion
1636 instead of the wave chunk
1637 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1638 not equal to a power of two
1639 - reimplementation of the filter algorithm. The new filter is more
1640 accurate and supports all gig filter types, including bandreject
1641 and lowpass turbo.
1642 - real support for 24 bit samples - samples are not truncated to
1643 16 bits anymore
1644 - support for aftertouch (channel pressure, not polyphonic
1645 aftertouch)
1646 - LFO1 behaviour fixed (dampening from max volume instead of
1647 amplifying from 0)
1648
1649 * LSCP server:
1650 - fixed application exit on broken pipe error (fixes bug #20)
1651 - fixed the notification messages delay due to lack of
1652 network activity (fixes bug #26)
1653 - fixed parser bug which occured on space(s) within device parameters
1654 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1655
1656 * audio driver:
1657 - added aRts audio output driver (by no means RT safe)
1658
1659 * MIDI driver:
1660 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1661 messages several times instead of once
1662 - API extension for MIDI drivers which already supply exact time stamps
1663 for events (i.e. for offline rendering based MIDI drivers)
1664 - added checks for bad MIDI data
1665
1666 * linuxsampler application:
1667 - show available sampler engine types on startup
1668
1669 * general changes:
1670 - support for muting sampler channels and solo mode of the same, two new
1671 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1672 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1673 introduced for this, the behavior is the same like on a mixer console
1674 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1675 --enable-process-muted-channels which can be used to enable the
1676 processing of muted channels.
1677 - support for sostenuto pedal
1678 - support for monitoring the total number of active voices
1679 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1680 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1681 - fixed some memory management errors
1682 - fixed some concurrency problems that could lead to crashes when
1683 LSCP commands were executed
1684 - fixed crash when instrument loading failed previously on the same
1685 sampler channel (fixes bug #36)
1686
1687 Version 0.3.3 (15 July 2005)
1688
1689 * packaging changes:
1690 - fixed compilation with gcc 4.0
1691
1692 * Gigasampler format engine:
1693 - LFO preprocessing was performed even though the respective LFO was
1694 disabled by the instrument patch (minor efficiency fix)
1695 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1696 for volume ramp downs in the same fragment (needed for current voice
1697 stealing implementation) then simply inform the user with a warning
1698 about possible click sounds and reduce the volume ramp down
1699 appropriately instead of cancelling the audio device connection
1700
1701 Version 0.3.2 (24 June 2005)
1702
1703 * packaging changes:
1704 - updated autotools build files to compile on OS X
1705 (conditional compilation of CoreMIDI and MidiShare drivers)
1706 - hand-crafted assembly optimization code can be disabled with
1707 './configure --disable-asm' (definitely not recommended)
1708 - fixed 'make dist' rule to include all necessary files
1709 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1710 (due to 'dist-bzip2' automake option)
1711
1712 * Gigasampler format engine:
1713 - support for the gig parameters for "release velocity response" curves
1714 - fine tuning of the EGADSR envelope
1715 - volume of release triggered samples now depends on note-on velocity,
1716 note length and gig parameter "release trigger decay" instead of
1717 note-off velocity.
1718 - revised voice stealing
1719 (fixes crash and endless loop caused by voice stealing)
1720 - don't reset scale tuning on instrument or audio output device change
1721 - handle key group conflicts right at the beginning of each fragment
1722 instead of when the respective voice is actually launched
1723 (fixes undefined behavior if stolen voices belonged to a key group -
1724 this case was followed by a "killed voice survived" error message)
1725 - fixed minor issue with null/silence samples
1726 (those stole voices even though they don't need a voice at all which
1727 resulted in "voice stealing didn't work out" messages)
1728 - don't reset volume, pan, pitch and MIDI controller values on
1729 instrument or audio output device change
1730
1731 * LSCP server:
1732 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1733 - fixed LSCP event "CHANNEL_INFO" notification
1734 (e.g. did not notify on volume changes or MIDI program change events)
1735
1736 * linuxsampler application:
1737 - added command line parameters --lscp-addr and --lscp-port to override
