NKSP: Reduced code for parsing NKSP variable declarations:

* Use 2 generalized grammar rules with optional components (i.e. optional
  value assignment and optional variable qualifiers) instead of previous
  linear combinations of grammar rules, which also fixes some edge case.

* Bumped version (2.1.1.svn44).

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
55 * Real-time instrument scripts:
56 - Added method ScriptVM::setExitResultEnabled() which allows to
57 explicitly enable the built-in exit() function to optionally accept
58 one function argument; the value of the passed exit() function
59 argument will then become available by calling
60 VMExecContext::exitResult() after script execution.
61 - 64 bit support for NKSP integer scripts variables (declare $foo).
62 - Variable names, function names and preprocessor condition names must start
63 with a regular character (a-z or A-Z); starting them with a digit or
64 underscore is not allowed.
65 - NKSP parser fix: equal comparison operator "=" and not equal comparison
66 operator "#" must only accept integer operands.
67 - NKSP language: Implemented support for standard units like Hertz, seconds,
68 Bel including support for metric unit prefixes; so one can now e.g.
69 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
70 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
71 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
72 - NKSP language: Introduced "final" operator "!" which is specifically
73 intended for synthesis parameter values to denote that the synthesis
74 parameter value is intended to be the "final" value for that synthesis
75 parameter that should explicitly be used by the engine and thus causing
76 the sampler engine to ignore all other modulation sources for the same
77 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
78 variable or formula with this new "!" operator the expression is marked as
79 being "final".
80 - NKSP script editor API: Added support for detecting standard unit tokens
81 and their potential metric prefix token.
82 - NKSP language: Added support for NKSP real number literals and
83 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
84 - NKSP language: Added support for NKSP real number (floating point) script
85 variables (declare ~foo).
86 - NKSP language: Added support for NKSP real number (floating point) array
87 script variables (declare ?foo[]).
88 - Built-in script function "message()" accepts now real number argument as
89 well.
90 - Added built-in script function "real_to_int()" and its short hand form
91 "int()" for casting from real number to integer in NKSP scripts.
92 - Added built-in script function "int_to_real()" and its short hand form
93 "real()" for casting from integer to real number in NKSP scripts.
94 - Allow built-in exit() function to potentially accept real number type
95 argument as well.
96 - Built-in script functions may have a different return type depending on
97 the arguments passed to the function.
98 - Built-in script function "abs()" optionally accepts and returns real
99 number.
100 - Built-in script functions "min()" and "max()" optionally accept real
101 number arguments and return real number as result in that case.
102 - NKSP VM API: Allow units and 'final'ness to be returned as result from
103 built-in functions (added methods VMFunction::returnUnitType() and
104 VMFunction::returnsFinal() for that purpose which must be implemented by
105 built-in function implementations).
106 - NKSP language: Allow metric unit prefixes of numeric scalar and array
107 variables to be changed freely at runtime (unlike unit types like Hz etc.
108 which are still sticky, parse-time features of variables which cannot be
109 changed at runtime for the intentional sake of determinism).
110 - NKSP language: 'final' values are prohibited for array variables for now
111 (attempt causes a parsers error).
112 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
113 conditions of runtime control structures like if(), while(), select()
114 (attempt causes a parser error).
115 - NKSP VM API: Allow built-in functions to perform their own, individual
116 parse time checks of arguments going to be passed to the function at
117 runtime (added method VMFunction::checkArgs() for that purpose).
118 - NKSP language: raise parser warning if only one operand of binary
119 operators (like logical 'or' comparison) contain a 'final' value (because
120 it would always yield in a 'final' result in such cases).
121 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
122 different metric unit prefixes, which will behave as expected (e.g.
123 result of expression '1000us < 2ms' is true).
124 - NKSP language: Allow adding values with different metric unit prefixes
125 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
126 - NKSP language: Allow subtracting values with different metric unit
127 prefixes (e.g. result of expression '1ms - 20us' is '980us').
128 - NKSP language: Allow multiplying with any metric unit prefixes
129 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
130 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
131 we don't have any considerable practical use for a term like '4s^2'
132 (hence any attempt multiplying two unit types still causes parser error).
133 - NKSP language: Allow dividing by any metric unit prefixes and allow
134 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
135 yields in unit free result '8'). So this is now a way to cast units away
136 e.g. for passing the result to other expressions, certain function calls
137 or variables which are not accepting any units (or that specific unit).
138 - NKSP language: integer arrays and real number arrays can now be converted
139 to strings (e.g. for dumping their content with message() calls for
140 script debugging purposes).
141 - NKSP language: expressions and variables with units are now correctly
142 casted to strings (e.g. with message() calls).
143 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
144 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
145 floating point tolerances into account.
146 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
147 VMScalarNumberExpr::evalCastReal().
148 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
149 'VMIntArrayExpr' and 'VMRealArrayExpr'.
150 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
151 unitFactor() (runtime) methods.
152 - Built-in function "exit()" supports now returning units and 'final'ness
153 for test cases.
154 - The following built-in functions support now units as well: "abs()",
155 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
156 "real_to_int()", "int()", "int_to_real()" and "real()".
157 - Built-in functions "array_equal()", "search()" and "sort()" support now
158 real number arrays (correctly) as well.
159 - Added individual parse time checks of arguments to be passed to built-in
160 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
161 "array_equal()" and "search()" specific for their individual purposes.
162 - NKSP VM refactoring: Renamed all methods, functions and classes matching
163 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
164 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
165 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
166 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
167 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
168 isScalarNumber() -> isNumber()).
169 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
170 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
171 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
172 as convenient methods for automatically converting values to expected
173 metric value basis.
174 - Built-in function "wait()" accepts now both integers and real numbers as
175 argument.
176 - NKSP VM API cleanup: Get rid of legacy method
177 VMFunction::argType(vmint iArg) which was already superseded by its new
178 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
179 - NKSP parser: if wrong argument type was passed to a built-in function and
180 that built-in function accepts more than one data type for the argument,
181 then show all supported data types as parser error message.
182 - Built-in function "play_note()" accepts now real numbers and seconds as
183 unit type as well for its 3rd and 4th function arguments.
184 - The following built-in functions accept now real numbers as well for their
185 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
186 "change_attack()", "change_decay()", "change_release()",
187 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
188 "change_cutoff_sustain()", "change_cutoff_release()",
189 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
190 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
191 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
192 - Fixed built-in function "change_play_pos()" not having accepted metric
193 prefixes at all.
194 - Fixed the following built-in functions having misinterpreted values given
195 with unit type (for their 2nd argument) as if they were relative values
196 (that is as if they were passed without a unit type): "change_attack()",
197 "change_decay()", "change_release()", "change_cutoff_attack()",
198 "change_cutoff_decay()", "change_cutoff_release()".
199 - Fixed the following built-in functions having applied completely wrong
200 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
201 respective EGs being their modulation sink assume uint data type with
202 value range 0..1000 instead of 0.0..1.0.
203 - Added individual parse-time checks of function arguments for the following
204 built-in functions: "play_note()", "note_off()", "set_event_mark()",
205 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
206 "change_decay()", "change_release()", "change_cutoff_attack()",
207 "change_cutoff_decay()", "change_cutoff_release()",
208 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
209 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
210 "change_pan_time()".
211 - Don't abort function call if unit type was used and at the same time
212 'final' operator was omitted for the primary value argument of the
213 following built-in functions: "change_cutoff()", "change_attack()",
214 "change_decay()", "change_release()", "change_cutoff_attack()",
215 "change_cutoff_decay()", "change_cutoff_release()",
216 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
217 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
218 "change_pan_time()", instead imply 'final'ness at runtime and raise an
219 appropriate parser warning at parse time.
220 - Added built-in real number functions "round()", "ceil()", "floor()",
221 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
222 "cos()", "tan()", "asin()", "acos()", "atan()".
223 - Added built-in script real number constant "~NI_MATH_PI".
224 - Added built-in script real number constant "~NI_MATH_E".
225 - NKSP language: Allow unary '+' operator.
226 - Added built-in script functions "msb()" and "lsb()".
227 - NKSP language: Added support for RPN event handler
228 ("on rpn ... end on" in instrument scripts).
229 - NKSP language: Added support for NRPN event handler
230 ("on nrpn ... end on" in instrument scripts).
231 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
232 may be read from the new RPN/NRPN script handlers to get the (N)RPN
233 parameter that had been changed and its new value.
234 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
235 which are identifying the new (N)RPN handlers as such at script runtime.
236 - Implemented built-in script function "set_rpn()".
237 - Implemented built-in script function "set_nrpn()".
238 - Fix: built-in functions returning an array type were broken and caused a
239 crash when the built-in function's (supposed to be array) result value was
240 used by the script VM.
241 - Removed upper value constraint for 2nd argument of built-in functions
242 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
243 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
244 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
245 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
246 the LFO frequency / resonance / cutoff frequency.
247 - Reduced code involved for parsing NKSP variable declarations by using 2
248 generalized grammar rules with optional components (i.e. optional value
249 assignment and optional variable qualifiers) instead of previous linear
250 combinations of grammar rules, which also fixes some edge case.
251
252 * test cases:
253 - Fixed compiler errors in test cases.
254 - Updated README for how to compile & run test cases.
255 - Updated test case
256 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
257 expected behaviour of the Mutex class implementation (recursive
258 mutex type).
259 - Added test cases for NKSP core language aspects and core built-in
260 functions.
261 - Fixed thread tests segfaulting on Linux.
262 - NKSP: Added real number test cases for built-in functions exit(),
263 int_to_real(), real(), real_to_int() and int(), as well as for the
264 plus, minus and negate language operators.
265 - Added massive amount of NKSP test cases for standard measuring units and
266 'final' operator usage cases.
267 - Added NKSP test cases for (floating point tolerance aware) real number
268 equalness / unequalness comparison.
269 - Added NKSP int array and real array tests for value assignment and
270 initialization of arrays.
271 - Added NKSP test cases for built-in functions "round()", "ceil()",
272 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
273 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
274 - Added NKSP test cases for unary '+' operator.
275 - Added NKSP test cases for core built-in variables.
276 - Added thorough NKSP test cases for variable declarations.
277
278 * GigaStudio/Gigasampler format engine:
279 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
280 behaviour for start_level_mid.
281 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
282 level (see discussion "GigaStudio LFO compatibility" on mailing list
283 from 2019-09-26 for details).
284 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
285 see discussion "GigaStudio LFO compatibility" on mailing list from
286 2019-09-26 for details).
287 - Format extension: Added support for different LFO wave forms (currently
288 either sine [default], triangle, saw or square).
289 - Format extension: Added support for LFO phase displacement (0��..360��).
290 - Format extension: Added support for flipping LFO polarity on LFO 3
291 (in the original gig format this was only available for LFO 1 and LFO 2).
292 - Format extension: Support for additional filter types:
293 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
294 bandreject 2-pole.
295 - Fixd potential crash with polynomial interpolator and max. pitch.
296 - If minimum cutoff is defined, remap cutoff controller CC values to really
297 span the entire possible cutoff range (and avoiding a dead controller
298 zone).
299
300 * SFZ format engine:
301 - Fixed support for regions with loccN/hiccN conditions on more than one
302 MIDI controller.
303
304 * Benchmarks:
305 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
306 algorithm (since result of 2nd run was not accumulated).
307 - Added benchmark for saw wave (benchmarks/saw.cpp).
308 - Added benchmark for sine wave (benchmarks/sine.cpp).
309 - Added benchmark for square wave (benchmarks/square.cpp).
310 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
311 which are large enough on modern systems.
312
313 Version 2.1.1 (27 Jul 2019)
314
315 * Real-time instrument scripts:
316 - Fixed behavior of built-in NKSP functions change_sustain(),
317 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
318 and change_cutoff_release().
319
320 * general changes:
321 - Only play release trigger samples on sustain pedal up if this behaviour
322 was explicitly requested by the instrument (otherwise only on note-off).
323 - Fixed compiler warnings.
324 - Fixed compilation error when cross-compiling to Mac.
325 - FX Sends: Provide more useful error messages on routing problems
326 (see bug #169).
327 - LSCP doc: Be more clear describing the two distinct approaches
328 of using external vs. internal effects (see bug #169).
329 - "optional" class: Fixed comparison operators.
330
331 * Gigasampler/GigaStudio format engine:
332 - Format extension: If requested by instrument then don't play release
333 trigger sample on note-off events.
334
335 * SFZ format engine:
336 - Fixed memory leak when releasing samples
337 (fixes bug #307, patch by Jacek Roszkowski)
338 - Fixed potential crash when a sample is shared by more than one region
339 (fixes bug #308, patch by Jacek Roszkowski).
340 - Opcode 'sample': Added support for built-in sample '*silence'
341 (fixes bug #310, patch by Jacek Roszkowski).
342
343 Version 2.1.0 (25 Nov 2017)
344
345 * SFZ format engine:
346 - added support for <global>, <master> and #define (patch by Alby M)
347 - Removed code duplication in SFZ file loading code.
348 - Added support for sfz extension opcode 'script' which may be used to
349 load real-time instrument script file (NKSP script language).
350 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
351 - Fixed unintended volume fade-in of voices under certain conditions.
352 - sfz parser: allow missing space between header and opcode
353
354 * Gigasampler/GigaStudio format engine:
355 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
356 cutoff settings.
357 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
358 all if an up-pitch of more than 40 semi tones was requested (I don't
359 think there is any stock gig sound that requires this behavior to
360 resemble its original sound).
361 - Added support for controlling whether the individual EGADSR stages may
362 be aborted (as LinuxSampler extension to the original GigaStudio 4
363 format).
364
365 * general changes:
366 - fixed printf type errors (mostly in debug messages)
367 - use unique_ptr instead of auto_ptr when building with C++11
368 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
369 allowing to sort data efficiently in real-time safe manner.
370 - RTList class: added methods for moving/inserting elements to arbitrary
371 position within a list.
372 - RTList class: added method fromPtr() for creating an Iterator object from
373 a raw element pointer.
374 - Attempt to partly fix resetting engine channels vs. resetting engine, an
375 overall cleanup of the Reset*(), ConnectAudioDevice(),
376 DisconnectAudioDevice() API methods would still be desirable though,
377 because the current situation is still inconsistent and error prone.
378 - Active voices are now internally grouped to "Note" objects, instead of
379 being directly assigned to a keyboard key. This allows more fine graded
380 processing of voices, which is i.e. required for certain instrument
381 script features.
382 - Fix: Release trigger voices were not spawned on sustain pedal up
383 (CC #64) events.
384 - Fix: Release trigger voices can now also distinguish correctly between
385 note-off and sustain pedal up events.
386 - All engines: Increased ramp speed of volume smoother and pan smoother
387 (while slow rate of crossfade smoother is preserved) to allow quick
388 volume and pan changes by instrument scripts for instance.
389 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
390 properly and thus were ignored for certain uses.
391 - Added new C++ API method
392 VirtualMidiDevice::SendChannelPressureToSampler().
393 - windows, 32-bit: fixed potential crashes by making sure the stack in
394 sub threads is 16-byte aligned
395 - fixed numerous compiler warnings
396 - Fixed invalid (note-on) event ID being assigned to new Note objects.
397 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
398 fixes potential undefined behavior.
399 - Fixed Note object leak when triggering notes on keys which did not
400 have a valid sample mapped (fixes bug #252).
401 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
402 - linuxsampler binary fix: option --create-instruments-db ignored
403 subsequent optional argument due to glibc's implementation oddity
404 which expects a "=" sign, but no space between them.
405
406 * packaging changes:
407 - removed unnecessary dependency to libuuid
408 (originated by libgig's usage of it)
409 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
410 auto detect whether it (sh/c)ould output its messages in color.
411 - Debian: Fixed packaging error about invalid "Source-Version"
412 substitution variable.
413 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
414 - Debian: Added build dependency to libsqlite3-dev for building
415 linuxsampler with instruments DB support.
416
417 * Real-time instrument scripts:
418 - Implemented scheduler for delayed MIDI events and for suspended scripts.
419 - Built-in script function "wait()": implemented support for function's
420 "duration-us" argument, thus scripts using this function are now
421 correctly resumed after the requested amount of microseconds.
422 - Built-in script function "play_note()": implemented support for
423 function's "duration-us" argument, thus notes triggered with this
424 argument are now correctly released after the requested amount of
425 microseconds.
426 - Fix: script events were not cleared when engine channel was reset,
427 potentially causing undefined behavior.
428 - Fixed crash which happened when trying to reference an undeclared
429 variable.
430 - Built-in script function "play_note()": Added support for passing
431 special value -1 for "duration-us" argument, which will cause the
432 triggered note to be released once the original note was released.
433 - Instrument script classes now exported with the liblinuxsampler C++ API.
434 - Added new API method ScriptVM::syntaxHighlighting() which provides
435 a convenient syntax highlighting backend for external instrument
436 script editor applications.
437 - Added new C++ API class "ScriptVMFactory".
438 - Extended parser issues to provide not only first line and first
439 column, but also last line and last column of issue (thus marking
440 the precise span of the issue within the source code).
441 - Reload script automatically after being modified by an instrument
442 editor.
443 - NKSP language grammar correction: allow empty event handler bodies
444 like "on note end on".
445 - Implemented built-in script function "change_vol()".
446 - Implemented built-in script function "change_tune()".

453 "event_status()" function.
454 - NKSP language: Added support for bitwise operators ".or.", ".and."
455 and ".not.".
456 - NKSP language scanner: Fixed IDs matching to require at least one
457 character (i.e. when matching function names or variable names).
458 - NKSP language scanner: disabled unusued rules.
459 - Fixed behavior of play_note() and note_off() functions which must
460 be distinguished engine internally from "real" MIDI note on/off
461 events in order to avoid misbehaviors like hanging notes.
462 - Implemented built-in script variable "$KSP_TIMER".
463 - Implemented built-in script variable "$NKSP_REAL_TIMER".

468 - NKSP language fix: division expressions were evaluated too often.
469 - NKSP language fix: string concatenation operator was right
470 associative instead of left (to right).
471 - NKSP language correction: allow empty statements in entire language
472 (i.e. "if end if").
473 - Implemented built-in script function "stop_wait()".

485 - Implemented built-in script function "change_decay()".
486 - Implemented built-in script function "change_release()".
487 - Fixed all change_*() built-in script functions to apply their
488 synthesis parameter changes immediately in case the respective note
489 was triggered at the same time, instead of scheduling the parameter
490 change, especially because it would cause some parameter types's
491 changes either to be ramped (i.e. change_vol()) or other types even
492 to have not effect at all (i.e. change_attack()).
493 - Implemented built-in script function "sh_left()".
494 - Implemented built-in script function "sh_right()".
495 - Implemented built-in script function "min()".
496 - Implemented built-in script function "max()".
497 - NKSP Fix: "init" event handler was not always executed when a script
498 was loaded.
499 - NKSP built-in wait() script function: abort script execution if
500 a negative or zero wait time was passed as argument (since this is
501 a common indication of a bug either of the script or even of the
502 engine, which could lead to RT instability or even worse).
503 - ScriptVM: Implemented automatic suspension of RT safety
504 threatening scripts.
505 - Provide more user friendly error messages on syntax errors.
506 - Fixed NKSP parser warning "Not a statement" when assigning an

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

581 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
582 - Added built-in constant $CALLBACK_STATUS_QUEUE.
583 - Added built-in constant $CALLBACK_STATUS_RUNNING.
584 - Removed max. value limitation of built-in functions "change_attack()",
585 "change_decay()" and "change_release()" to i.e. allow passing 2000000
586 for doubling the respective time.
587 - NKSP script editor syntax highlighting API: Fixed app termination due
588 to a lexer start condition stack underrun.
589 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
590 USE_CODE_IF_NOT() preprocessor statements.
591 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
592 can be set to disable all subsequent built-in "message()" function calls
593 on preprocessor level.
594 - Implemented built-in script function "change_sustain()".

631 configure
632 - Mac OS X: Makefile fix for the install-strip target
633 - fixed compilation with gcc 4.7
634 - fixed configure script error with old autoconf versions
635 - lsatomic.h: use gcc provided atomic functions if building with
636 gcc 4.7 and C++11
637 - modernized configure script
638 - fixed linkage error when building with
639 LDFLAGS="-Wl,--no-undefined" (#190)
640 - fixed compilation with Clang 3.2
641 - removed usage of deprecated Automake variable INCLUDES
642 - fixed building with C++11
643 - build fix: ChangeFlagRelaxed.h was missing in makefile
644 - build fix: libsndfile compiler flags were missing in some
645 makefiles
646 - fix for building with bison 3.0 (#202)
647 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
648 on the process's main thread
649 - fixed build error on newer MinGW
650 - support building with older jack versions
651 - support building with spaces in vst sdk path
652 - enabled automake 'subdir-objects' option and moved external

654 in order to get rid of warnings from automake 1.14
655
656 * general changes:
657 - Refactoring: moved the independent code from
658 the Gigasampler format engine to base classes
659 - command line option '--profile' is currently disabled, since the
660 respective profiling code is currently broken
661 - Introduced support for optional environment variable
662 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
663 where the sampler shall look for instrument editor plugins
664 (patch by Luis Garrido, slightly modified).
665 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
666 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
667 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
668 note (in this implementation of the sampler its simply hard routed to
669 the 1st effect send of the sampler channel, no matter what the actual
670 effect type is)
671 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
672 note (in this implementation of the sampler its simply hard routed to
673 the 2nd effect send of the sampler channel, no matter what the actual
674 effect type is)
675 - implemented support for internal LADSPA effects
676 - raised limit of program change queue from 100 to 512
677 (as suggested by Alex Stone)
678 - implemented sine LFO, pulse LFO and saw LFO
679 - experimental support for per voice equalization
680 - added command line option --exec-after-init
681 - Introduced new C++ API method:
682 EngineChannel::InstrumentFileName(int index)
683 allowing to retrieve the whole list of files used for the loaded
684 instrument on an engine channel (a.k.a. part). Some GigaStudio
685 instruments for example are splitted over several files like
686 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
687 - Added new C++ API method Sampler::GetGlobalMaxVoices().
688 - Added new C++ API method Sampler::GetGlobalMaxStreams().
689 - Added new C++ API method Sampler::SetGlobalMaxVoices().
690 - Added new C++ API method Sampler::SetGlobalMaxStreams().
691 - Various "const" and "restrict" optimizations.
692 - all engines: add pan CC value to instrument pan parameter before
693 applying panning, instead of using two separate pan functions in
694 series (#182)
695 - added a lock guard class for exception safe mutex handling and
696 used it everywhere appropriate
697 - Immediately apply scale tuning changes to active voices.
698 - Exposed scale tuning to C++ API (along to the already existing standard
699 SysEx way).
700 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
701 and broken for ppc64. (Seq_cst loads and stores are actually not
702 used in LS, so the bug wasn't noticable.)
703 - lsatomic.h: added ARMv7 support
704 - Added support for multiple MIDI input ports per sampler channel (and
705 added various new C++ methods for this new feature / design change, old
706 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
707 as deprecated but are still there and should provide full behavior
708 backward compatibility).
709 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
710 unsafe and caused compilation error with clang 2.x).
711 - Bugfix: only process the latest MIDI program change event.
712 - Introducing the LSCP shell, which provides convenient control of the
713 sampler from the command line by providing LSCP aware features.
714 - VirtualMidiDevice: Added support for program change.
715 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
716 - VirtualMidiDevice: Added support for pitch bend.
717 - Aftertouch: extended API to explicitly handle channel pressure and
718 polyphonic key pressure events (so far polyphonic pressure was not
719 supported at all, and channel pressure was rerouted as CC128 but not
720 used so far).
721 - Added initial support for real-time instrument scripts. The script VM
722 code is shared by all sampler engine implemementations, however only the
723 gig file format currently provides support for storing instrument scripts
724 (as LinuxSampler extension to the original GigaStudio 4 format).
725
726 * Gigasampler format engine:
727 - implemented the "round robin keyboard" dimension
728 - fixed round robin and random dimensions for cases when number of
729 dimension zones is not a power of two

731 key
732 - bugfix: pitch LFO controller "internal+aftertouch" was broken
733 - bugfix: filter keyboard tracking was broken
734 - filter performance fix (an unnecessary copy was made of the
735 filter parameters in each sub fragment)
736 - handle special case when pan parameter in gig file has max or
737 min value
738 - Exclusive Groups: don't ever stop voices of the same note,
739 doesn't sound naturally with a drumkit
740 - fixed EG1 modulation when attack or release is zero
741 - Fixed support for 'aftertouch' attenuation controller.
742 - Fixed crash that happened with velocity split sounds under certain
743 conditions (see also previous commit on libgig).
744 - fixed behaviour of filter LFO
745
746 * SFZ format engine:

776 - added support for loop_mode=one_shot
777 - fixed playback of 16 bit wav files on big endian CPUs
778 - added support for Ogg Vorbis sample files
779 - use loop markers from sample file if loop_start and loop_end are
780 not set in sfz file
781 - implemeted filters. Filter types: lowpass, bandpass, bandreject
782 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
783 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
784 cutoff_cc, cutoff_chanaft.
785 - bugfix: zero ampeg_sustain didn't work

922 - Listen to all interfaces on Mac OS X (INADDR_ANY)
923 - VST bugfix: If the host called resume() before and after
924 changing sample rate or block size, the number of channels was
925 incorrectly set to two. This caused silence in Cubase 5.
926 - save engine type (gig, sfz or sf2) in plugin state

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

1148 crashes and noise on such transitions).
1149 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1150 (fixes #208)
1151 - Fixed bug in LSCP grammar definition which caused a statement like
1152 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1153 practically irrelevant, however it caused problems with the new LSCP
1154 shell's auto completion feature).
1155 - Fixed MIDI program change messages being ignored if quickly executed
1156 after each other (fixes #231).
1157
1158 Version 1.0.0 (31 July 2009)
1159
1160 * packaging changes:
1161 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1173 directory of liblinuxsampler dll (look in the same directory and one
1174 directory above)
1175 - configure script fix: removed unconditional use of SSE
1176 - fixed building with sqlite installed in a non-standard directory
1177 - when cross-compiling, don't try to create instruments.db
1178 - fix for new mingw-w64 version, which has usleep
1179
1180 * general changes:
1181 - bugfix: on some POSIX systems instrument editor plugins refused to
1182 load as we used a non-portable Linux specific struct field
1183 (fixes bug #70, patch by Ronald Baljeu)
1184 - fixed endless loop which occured when loading an instrument editor
1185 plugin DLL on Windows systems failed
1186 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1187 - optimized the SynchronizedConfig class so it doesn't wait
1188 unnecessarily long after an update

1190 events (e.g. to highlight the pressed keys on the virtual keyboard
1191 of gigedit)
1192 - added support for triggering notes by instrument editors (see above)
1193 - be verbose on DLL load errors (on Linux)
1194 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1196 implementation, which is usually faster)
1197 - fixes for audio drivers with varying buffer sizes
1198 - experimental support for running LinuxSampler as a DSSI, LV2 and
1199 VST plugin

1205 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1206 - automatic stacktrace mechanism is now turned off by default and can
1207 be switched on by command line option "--stacktrace" (the automatic
1208 stacktrace mechanism seems to be broken on most systems at the moment)
1209 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1210 a pointer to the launched InstrumentEditor object
1211 - added optional 3rd party user data parameter for following
1212 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1213 InstrumentEditor::Launch(),
1214 InstrumentManager::LaunchInstrumentEditor()
1215 - theoretical fix: made SynchronizedConfig follow C++0x memory
1216 model more strictly
1217 - fixes for using large audio device buffers
1218 - Windows: add the installation directory to the DLL search path
1219 when loading an editor plugin (solves problems with VST and

1222
1223 * audio driver:
1224 - removed the nonsense audio channel constraint (which was hard coded to
1225 max. 100 audio channels) for most audio drivers
1226 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1227 opposed to the LSCP specs
1228 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1229 reflected the wrong value
1230 - fixed a memory management bug in ASIO driver
1231 - Makefile fix: JACK_CFLAGS wasn't used
1232 - JACK: use jack_client_open instead of the deprecated

1239 win64)
1240 - VST: added support for sample rate and buffer size changes
1241 - VST: close editor (Fantasia) when the VST is removed
1242 - VST: avoid opening Fantasia more than once for each VST instance
1243 - VST: export main function as "main" on Linux too (fix for
1244 energyXT)
1245 - VST: changed number of output channels from one stereo to 16
1246 stereo
1247 - added channel routing, fxsends and midi maps to the settings
1248 stored in the plugin state
1249 - performance optimization of AudioChannel::MixTo() and
1250 AudioChannel::CopyTo() methods using GCC vector exensions
1251 (if available)

1253 exception when getting parameters from a disconnected device
1254
1255 * MIDI driver:
1256 - added JACK MIDI driver
1257 - dispatch bank select as ordinary CC as well, the user might seriously
1258 want to (mis)use it for some purpose ("fixed" in all current MIDI
1259 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1260 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1261 CoreMidi or AU
1262 - fixed mingw-w64 compilation error in MME driver
1263 - made program change handling in MIDI thread real-time safe by
1264 moving the logic to a non-RT thread
1265 - fixed minor memory leak in ALSA driver
1266
1267 * instruments database:
1268 - avoid time consuming samples scanning when adding instruments
1269 to the instruments database
1270 - added support for handling lost files in the instruments database
1271 - Implemented option for adding instruments in separate directories
1272 in the instruments database
1273 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1274 - work-around for missing fnmatch function on Windows to make
1275 instrument database compilable
1276 - added instrument database support on Windows
1277 works with both standalone mode and VST plugin.
1278 the instruments DB file is located in
1279 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1280 databases for each windows user
1281 if no DB is present it automatically creates the .linuxsampler subdir
1282 and then creates an empty DB
1283 - fixed recursive import, which was broken on Windows
1284
1285 * Gigasampler format engine:
1286 - fixed a memory leak that could happen when a channel was deleted
1287 while notes were playing
1288 - made it possible to load an instrument even if the audio thread
1289 isn't running
1290 - added partial support for the "Controller Triggered" MIDI rule,
1291 enough for piano gigs with pedal noise samples
1292 - minor fix: only mark FX sends as being modified if really the
1293 respective FX send MIDI controller was used
1294 - added support for GM global device volume SysEx message
1295 (can be selected at compile time to either apply globally to the
1296 whole sampler [default] or only to the sampler channels that are
1297 connected to the respective MIDI input port the SysEx message arrived
1298 on)
1299 - bugfix: notes triggered at position 0 in the audio buffer were
1300 sometimes wrongly killed in the same buffer, causing no sound to
1301 be played
1302 - added support for chromatic / drumkit mode Roland GS Sysex message
1303 which is usally used to switch a part between chromatic sounds and
1304 drumkit sounds (as opposed to their common default setting of MIDI
1305 part 10 being a drumkit part and all other ones chromatic parts), in
1306 LS however one can switch between the first 16 MIDI instrument maps
1307 defined for the sampler
1308 - made it possible to create multiple sample channels even if the
1309 audio thread isn't running
1310 - fixed crash when removing channel with active voices (#116)
1311 - bugfix: on sample reference changes (instrument editor), only
1312 un-cache the respective sample if it's really not used by any
1313 sampler engine anymore
1314 - re-cache samples in case they were changed by an instrument editor,
1315 e.g. when a sample was added while playing (#82)
1316 - fixed hanging notes which occured when note-off event had the exact
1317 same time stamp as the voice's note-on event and occured both in the
1318 same audio fragment cycle (fixes bug #112)
1319 - added support for the "fine tune" and "pitch bend range"
1320 instrument-level gig parameters
1321 - fixed minor artifacts in pitch bend handling
1322 - added support for GS Reset SysEx message
1323 - allow gig files to use unlimited downward pitch shifting
1324 - added a limit check for upward pitch shifting
1325 - bugfix: sometimes, when playing a note twice fast, the second
1326 note was silent
1327 - fixed crash happening when a pitch bend event arrived at the
1328 same time a new instrument was loading
1329
1330 * LSCP server:
1331 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1332 react on MIDI data arriving on certain sampler channels (so far only
1333 Note-On and Note-Off events are sent via this LSCP event)
1334 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1335 react on MIDI data arriving on certain MIDI input devices (so far only
1336 Note-On and Note-Off events are sent via this LSCP event)
1337 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1338 SET DB_INSTRUMENT FILE_PATH
1339 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1340 frontends to send MIDI messages to specific sampler channel
1341 - added two additional fields to GET FILE INSTRUMENT INFO command -
1342 KEY_BINDINGS and KEYSWITCH_BINDINGS
1343 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1344 was incorrect
1345 - Optimized the retrieval of the MIDI instrument mappings
1346 - added new LSCP command "SET VOICES" to globally alter the maximum
1347 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1348 be triggered respectively
1349 - added new LSCP command "SET STREAMS" to globally alter the maximum
1350 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1351 which will be triggered respectively
1352 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1353 a gigedit file dialog is opened)
1354 - close all connections when LSCPServer is deleted
1355 - hard close of all sockets on exit
1356 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1357 driver
1358
1359 * Bug fixes:
1360 - fixed a crash which occurs when removing a sampler channel waiting
1361 to start instrument loading after another channel
1362 - fixed a crash which occurs when removing a sampler channel with
1363 instrument loading in progress (bug #113)
1364 - fixed termination caused by uncaught exception when adding MIDI
1365 instrument with PERSISTENT load mode
1366 - fixed possible iterator invalidations when resetting the sampler
1367 - fixed memory leaks when issuing the following LSCP commands:
1368 GET AUDIO_OUTPUT_DRIVER INFO
1369 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1370 GET MIDI_INPUT_DRIVER INFO
1371 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1372 - fixed possible compilation error when sqlite is not present
1373 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1374 - fixed crash when changing the audio output device of a sampler
1375 channel with loaded instrument and start playing notes
1376 - fixed endless loop in Engine::SuspendAll() (bug #120)
1377 - fixed a low-level atomic load function that was broken on 64-bit
1378 PowerPC, which probably could cause crashes on that platform
1379 - fixed a memory management error which could cause a crash when a
1380 plugin was unloaded
1381 - bugfix: two private structs had the same name, which could cause
1382 problems if the linker chose the wrong constructor
1383 - fixed low-level ConditionServer usage bug that caused lockups on
1384 Windows
1385
1386
1387 Version 0.5.1 (6 December 2007)
1388
1389 * packaging changes:
1390 - added autoconf checks for pthread library
1391 - added autoconf check for pthread bug found on certain NPTL-enabled
1392 glibc versions (see Gentoo bug report #194076)
1393 - added autoconf checks for MS Windows
1394
1395 * general changes:
1396 - bugfix: the thread used by an editor plugin didn't die when the
1397 editor closed
1398 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1399 out all the space. operator--() did not apply size_mask after
1400 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1401 order to avoid problems with the _NonVolatileReader functions.
1402 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1403 GetWriteSpace(). Since this function is currently only used in
1404 the stream's qsort() compare function, it didn't trigger any
1405 bugs.
1406 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1407 24bit mode too. Faster method to read 24bit words on little
1408 endian machines (x86): replaced 3 byte reads + shifts with a 1
1409 unaligned 32bit read and shift
1410 - experimental support for MS Windows (MIDI input via MME, AUDIO
1411 output via ASIO)
1412 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1413 - support for monitoring the total number of active disk streams
1414 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1415 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1416
1417 * AUDIO driver:
1418 - added Windows ASIO low latency audio driver
1419
1420 * MIDI driver:
1421 - added MME Windows MIDI driver
1422
1423 * LSCP server:
1424 - added support for Windows style path / filenames, however with
1425 forward slash path separators instead of backslash
1426 (i.e. "C:/foo/bar.gig")
1427 - allow naughty liblscp to send non-string device parameters within
1428 apostrophes as well
1429 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1430 "LIST FILE INSTRUMENTS <file>" and
1431 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1432 about an arbitrary instrument file on the system where the sampler is
1433 running on
1434
1435 Version 0.5.0 (15 October 2007)
1436
1437 * packaging changes:
1438 - config.h is not going to be installed along with liblinuxsampler's
1439 API header files anymore
1440 - only the API relevant header (and source) files will be exported to
1441 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1442 - added completely new XCode project files for Mac OSX which is now
1443 capable to execute our autoconf environment, thus no need anymore
1444 to maintain the compile time configuration file (osx/version.h) for
1445 OSX manually (patch by Toshi Nagata)
1446 - fixed buggy boolean --enable-foo / --disable-foo configure script
1447 parameters
1448 - global.h now only covers global definitions that are needed for the
1449 C++ API header files, all implementation internal global definitions
1450 are now in global_private.h
1451 - atomic.h is not exposed to the C++ API anymore
1452 - no need to include config.h anymore for using LS's API header files
1453 - fixed warnings in API doc generation
1454
1455 * general changes:
1456 - replaced the old, confusing MIDI program change mechanism by a
1457 flexible MIDI instrument mapper which allows to map arbitrary
1458 (MIDI bank, MIDI program) pairs with arbitrary
1459 (engine type, instrument file, file index) triplets which will be
1460 loaded on the respective channel when such MIDI program change
1461 messages arrive, beside that, each entry allows to define a life-time
1462 strategy for the instrument, so the user can define whether the
1463 instrument should i.e. be permanently loaded (to be able to switch
1464 quickly among sounds) or i.e. loaded just on demand when the
1465 respective program change arrives (to safe RAM space), as well as a
1466 global volume factor for each entry, so the user can adjust the volume
1467 dynamic of his mapped instrument collection without having to modify
1468 the instrument files, also one can manage arbitrary amount of such
1469 MIDI instrument maps and assign each sampler channel individually
1470 a certain map, so that i.e. separation of normal instruments and
1471 drumkits is possible
1472 - new notification events for tracking changes to audio/MIDI devices,
1473 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1474 - sampler was limited to load max. 200 instruments in the background
1475 due to a constant size RingBuffer FIFO which is now replaced by a
1476 dynamic (unlimited) size std::list FIFO
1477 - added FX sends, these allow to route audio signals to arbitrary audio
1478 output channels for being processed by external effect processors
1479 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1480 controllers
1481 - global (sampler wide) volume can now be controlled at runtime
1482 - Implemented new, improved notification system
1483 - fixed compilation errors regarding OSX
1484 (patch by Toshi Nagata)
1485 - implemented instruments database
1486 - added support for escape sequences to the instruments database
1487 - added highly experimental support for on-the-fly instrument editing
1488 within the sampler's process (by using instrument editor plugins),
1489 you'll notice the new "Registered instrument editors:" message on
1490 startup, added a new LSCP command:
1491 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1492 to spawn a matching instrument editor for the instrument on the
1493 given sampler channel, the plugin path can be overridden at compile
1494 time with ./configure --enable-plugin-dir=/some/dir
1495 - added experimental code for synchronizing instrument editors hosted
1496 in the sampler's process to safely edit instruments while playing
1497 without a crash (hopefully) by either suspending single regions
1498 wherever possible or if unavoidable whole engine(s)
1499 - fixed several issues in fundamental "Thread" class: set scheduling
1500 policy and priority on thread level, set a minimum stack size for
1501 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1502 threads simply inherited properties of starting thread instead of
1503 setting their own policy and priority
1504 - minor fix in our automatic stack trace mechanism on crashes, the
1505 main process did not wait for the stack trace process to finish
1506 its output
1507 - fixed some minor memory leaks
1508 - reenabled assembly features support, at the moment only for
1509 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1510 - minor assembly fix in x86 features detection (don't use the PIC
1511 register, to avoid relocations in the text segment at runtime)
1512 - POSIX callback functions of Thread.h are hidden
1513
1514 * MIDI driver:
1515 - dispatch bank select (MSB and LSB) messages
1516
1517 * audio driver:
1518 - the ALSA audio output driver parameters now reflect the correct
1519 parameter value ranges for the respective selected sound card
1520 (patch by Till Wimmer, a bit fixed and extended)
1521
1522 * Gigasampler format engine:
1523 - if a filter is used and EG2 finishes before EG1, let the voice
1524 die when EG2 has finished (this fixes a problem with clicks and
1525 voice starvation for some gigs)
1526 - playback is no longer disabled during instrument loading
1527 - all notes playing on a channel that changes its instrument keep
1528 playing with the old instrument until they get a note off
1529 command
1530 - EG fix: a release value of zero could cause noises or crash
1531 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1532 - EG fine tuning: when attack is zero the EG starts at a level
1533 above max sustain level, which means that there is a decay phase
1534 even if sustain is 100%
1535 - more EG fixes: the level could sometimes go below zero and cause
1536 noises or crashes
1537 - minor fix of EGDecay (patch by Toshi Nagata)
1538 - fixed compiler error when --enable-override-filter-type was
1539 supplied to the configure script (fixes #46)
1540 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1541 instead of a fix value
1542 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1543 127 (solo mode) only kill voices if the respective mode really
1544 changed
1545
1546 * LSCP server:
1547 - fixed compile time error for old Bison versions
1548 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1549 - parser now supports extended ASCII character set
1550 (up to ASCII code 255, i.e. includes now umlauts and accents)
1551 - filename arguments in LSCP commands now allow to use escape
1552 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1553 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1554 code value like \xf2) (fixes bug #24)
1555 - the following LSCP commands now also support escape sequences for at
1556 least one of their text-based parameters (i.e. name, description):
1557 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1558 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1559 "SET DB_INSTRUMENT_DIRECTORY NAME",
1560 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1561 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1562 "FIND DB_INSTRUMENT_DIRECTORIES"
1563 - returns verbose syntax errors (line and column where syntax error
1564 occured, the unexpected character and the actually expected, possible
1565 character(s), the latter only if less than 5 possibilities)
1566 - made sure that LSCP syntax is not affected by gigedit locale
1567 settings
1568 - bugfix regarding strings parameter lists: all comma separated lists
1569 of strings were treated as being one string containing commas
1570 (fixes #57)
1571
1572 * Bug fixes:
1573 - fixed crash occurring on certain LSCP scripts (Bug 39)
1574 - another thread safety fix for lscp "load engine" and "set
1575 channel audio output device"
1576 - fixed a crash which occurs when reassigning the same engine
1577 on a sampler channel with connected MIDI device
1578 - fixed a crash which occurs when changing the number of ports of a MIDI
1579 device connected to a sampler channel to number less then or equal
1580 to the index of the port to which the sampler channel is connected.
1581 - The previous bindings were not been disconnected when altering
1582 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1583 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1584 - The active stream/voice count statistic was incorrect.
1585 - notification events were not been sent for some sampler
1586 channel changes
1587 - added default min and max values to restrict the number of allowed
1588 audio output channels and MIDI input ports
1589 - the connection to the PCM interface is now closed when destroying
1590 an audio output device
1591 - files with slash in their path or filename could not be loaded
1592
1593 * test cases:
1594 - updated and fixed (haven't been touched in a while)
1595
1596 Version 0.4.0 (24 November 2006)
1597
1598 * packaging changes:
1599 - changed deprecated copyright attribute to license; added ldconfig
1600 to post-(un)install steps; added devel package for liblinuxsampler;
1601 to linuxsampler.spec (RPM)
1602 - install necessary development header files for allowing 3rd party
1603 applications to link against liblinuxsampler
1604 - liblinuxsampler's API documentation can be generated with 'make docs'
1605 (Doxygen required)
1606 - added benchmark to automatically detect the best triangle LFO
1607 implementation (currently either an integer math solution or a
1608 di-harmonic approximation), automatic detection can be overriden
1609 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1610 configure script argument though (mandatory for cross-compilation)
1611 - do not automatically pick optimized gcc flags if the user already
1612 provided some on his own (as CXXFLAGS)
1613 - added compile time option to disable processing of All-Notes-Off MIDI
1614 messages
1615 - added compile time options to allow disabling the various audio and
1616 MIDI drivers
1617 - fixed automatic GCC CPU switch detection on PPC
1618 (patch by Ebrahim Mayat)
1619
1620 * Gigasampler format engine:
1621 - extensive synthesis optimization
1622 (reimplementation of EGs and LFO(s), removed synthesis parameter
1623 prerendering and the synthesis parameter matrix in general, splitting
1624 each audio fragment into subfragments now where each subfragment uses
1625 constant pitch and filter coefficients. The volume coefficient is
1626 linearly interpolated inside a subfragment, unless
1627 --disable-interpolate-volume is set.)
1628 - fine tuning of the EG modulation parameters
1629 - improved filter cutoff calculation by adding support for the
1630 following gig parameters: Cutoff freq (used when no cutoff
1631 controller is defined), Control invert, Minimum cutoff, Velocity
1632 curve and Velocity range. The keyboard tracking now scales
1633 cutoff frequency instead of resonance.
1634 - added support for gig parameter Resonance.
1635 - fixed bug in sysex handling (patch by Juan Linietsky)
1636 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1637 which can be overridden with --enable-global-attenuation
1638 - EG fixes: made the length of "attack hold" stage more
1639 accurate. Release stage can now start before attack stage
1640 ends. Cancel release didn't work when sustain was zero. Attack
1641 time now has a minimal value to prevent clicks.
1642 - fixed pitch changes larger than one octave
1643 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1644 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1645 all modes can be altered via standard GM messages, that is CC5 for
1646 altering portamento time, CC65 for enabling / disabling portamento
1647 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1648 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1649 parameter) and crossfade
1650 - added support for the "attenuation controller threshold" gig
1651 parameter
1652 - added smoothing of volume changes caused by control change
1653 messages
1654 - sample loop parameters are now taken from the DimensionRegion
1655 instead of the wave chunk
1656 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1657 not equal to a power of two
1658 - reimplementation of the filter algorithm. The new filter is more
1659 accurate and supports all gig filter types, including bandreject
1660 and lowpass turbo.
1661 - real support for 24 bit samples - samples are not truncated to
1662 16 bits anymore
1663 - support for aftertouch (channel pressure, not polyphonic
1664 aftertouch)
1665 - LFO1 behaviour fixed (dampening from max volume instead of
1666 amplifying from 0)
1667
1668 * LSCP server:
1669 - fixed application exit on broken pipe error (fixes bug #20)
1670 - fixed the notification messages delay due to lack of
1671 network activity (fixes bug #26)
1672 - fixed parser bug which occured on space(s) within device parameters
1673 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1674
1675 * audio driver:
1676 - added aRts audio output driver (by no means RT safe)
1677
1678 * MIDI driver:
1679 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1680 messages several times instead of once
1681 - API extension for MIDI drivers which already supply exact time stamps
1682 for events (i.e. for offline rendering based MIDI drivers)
1683 - added checks for bad MIDI data
1684
1685 * linuxsampler application:
1686 - show available sampler engine types on startup
1687
1688 * general changes:
1689 - support for muting sampler channels and solo mode of the same, two new
1690 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1691 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1692 introduced for this, the behavior is the same like on a mixer console
1693 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1694 --enable-process-muted-channels which can be used to enable the
1695 processing of muted channels.
1696 - support for sostenuto pedal
1697 - support for monitoring the total number of active voices
1698 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1699 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1700 - fixed some memory management errors
1701 - fixed some concurrency problems that could lead to crashes when
1702 LSCP commands were executed
1703 - fixed crash when instrument loading failed previously on the same
1704 sampler channel (fixes bug #36)
1705
1706 Version 0.3.3 (15 July 2005)
1707
1708 * packaging changes:
1709 - fixed compilation with gcc 4.0
1710
1711 * Gigasampler format engine:
1712 - LFO preprocessing was performed even though the respective LFO was
1713 disabled by the instrument patch (minor efficiency fix)
1714 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1715 for volume ramp downs in the same fragment (needed for current voice
1716 stealing implementation) then simply inform the user with a warning
1717 about possible click sounds and reduce the volume ramp down
1718 appropriately instead of cancelling the audio device connection
1719
1720 Version 0.3.2 (24 June 2005)
1721
1722 * packaging changes:
1723 - updated autotools build files to compile on OS X
1724 (conditional compilation of CoreMIDI and MidiShare drivers)
1725 - hand-crafted assembly optimization code can be disabled with
1726 './configure --disable-asm' (definitely not recommended)
1727 - fixed 'make dist' rule to include all necessary files
1728 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1729 (due to 'dist-bzip2' automake option)
1730
1731 * Gigasampler format engine:
1732 - support for the gig parameters for "release velocity response" curves
1733 - fine tuning of the EGADSR envelope
1734 - volume of release triggered samples now depends on note-on velocity,

1736 note-off velocity.
1737 - revised voice stealing
1738 (fixes crash and endless loop caused by voice stealing)
1739 - don't reset scale tuning on instrument or audio output device change
1740 - handle key group conflicts right at the beginning of each fragment
1741 instead of when the respective voice is actually launched

1743 this case was followed by a "killed voice survived" error message)
1744 - fixed minor issue with null/silence samples
1745 (those stole voices even though they don't need a voice at all which
1746 resulted in "voice stealing didn't work out" messages)

1748 instrument or audio output device change
1749
