NKSP: Added support for RPN and NRPN event handlers:

* NKSP language: Added support for RPN event handler
  ("on rpn ... end on" in instrument scripts).

* NKSP language: Added support for NRPN event handler
  ("on nrpn ... end on" in instrument scripts).

* Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
  may be read from the new RPN/NRPN script handlers to get the (N)RPN
  parameter that had been changed and its new value.

* Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
  which are identifying the new (N)RPN handlers as such at script runtime.

* Bumped version (2.1.1.svn30).

1 Version SVN trunk (?)

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

433 - Implemented built-in script function "dec()".
434 - NKSP language fix: division expressions were evaluated too often.
435 - NKSP language fix: string concatenation operator was right
436 associative instead of left (to right).
437 - NKSP language correction: allow empty statements in entire language
438 (i.e. "if end if").

453 - Fixed all change_*() built-in script functions to apply their
454 synthesis parameter changes immediately in case the respective note
455 was triggered at the same time, instead of scheduling the parameter
456 change, especially because it would cause some parameter types's
457 changes either to be ramped (i.e. change_vol()) or other types even
458 to have not effect at all (i.e. change_attack()).
459 - Implemented built-in script function "sh_left()".
460 - Implemented built-in script function "sh_right()".
461 - Implemented built-in script function "min()".
462 - Implemented built-in script function "max()".

464 was loaded.
465 - NKSP built-in wait() script function: abort script execution if
466 a negative or zero wait time was passed as argument (since this is
467 a common indication of a bug either of the script or even of the
468 engine, which could lead to RT instability or even worse).
469 - ScriptVM: Implemented automatic suspension of RT safety
470 threatening scripts.

483 - Implemented built-in script function "fade_out()".
484 - Fixed acceptance of wrong data type of parameters passed to built-in
485 script functions "change_vol()", "change_tune()", "change_pan()",
486 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
487 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

489 - Added built-in script function "get_event_par()" and implemented some
490 of its possible parameter selections.
491 - Added built-in script function "set_event_par()" and implemented some
492 of its possible parameter selections.
493 - Fixed a bunch of scheduler time related bugs.
494 - Fixed polyphonic variables not being reset to zero after usage.
495 - Built-in "ignore_event()" function: argument is now optional, like with
496 built-in function "ignore_controller()".
497 - Implemented built-in script function "change_velo()".
498 - Implemented built-in script function "change_note()".
499 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
500 intuitive behavior if used in combination with "change_vol_time()" or
501 "change_tune_time()" respectively: now tuning/volume changes are only
502 assigned (without delay) immediately to a new note if the respective
503 timing function has not been called before, otherwise the volume/tuning
504 changes are automatically faded (before, only the event's time stamp was
505 relevant).
506 - Implemented built-in script function "array_equal()".
507 - Implemented built-in script function "search()".
508 - Implemented built-in script function "sort()".
509 - NKSP Fix: Never suspend "init" event handlers.

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

549 - Added built-in constant $CALLBACK_STATUS_RUNNING.
550 - Removed max. value limitation of built-in functions "change_attack()",
551 "change_decay()" and "change_release()" to i.e. allow passing 2000000
552 for doubling the respective time.
553 - NKSP script editor syntax highlighting API: Fixed app termination due
554 to a lexer start condition stack underrun.
555 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
556 USE_CODE_IF_NOT() preprocessor statements.
557 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
558 can be set to disable all subsequent built-in "message()" function calls
559 on preprocessor level.
560 - Implemented built-in script function "change_sustain()".
561 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
562 to avoid the editor app to crash on ill-formed text input.

574 undefined behavior.
575 - Cleanup of instruments DB file creation and opening code.

577 is now optional, if it is missing, then a default location is used.
578 - Added support for scanning SFZ (.sfz) files.
579 - Added support for scanning Sound Font (.sf2) files.
580 - Fixed undefined DB transaction behavior.

595 directories are separate
596 - Mac OS X: made it possible to specify plugin installation dir to
597 configure
598 - Mac OS X: Makefile fix for the install-strip target
599 - fixed compilation with gcc 4.7
600 - fixed configure script error with old autoconf versions
601 - lsatomic.h: use gcc provided atomic functions if building with
602 gcc 4.7 and C++11
603 - modernized configure script
604 - fixed linkage error when building with
605 LDFLAGS="-Wl,--no-undefined" (#190)
606 - fixed compilation with Clang 3.2
607 - removed usage of deprecated Automake variable INCLUDES
608 - fixed building with C++11
609 - build fix: ChangeFlagRelaxed.h was missing in makefile
610 - build fix: libsndfile compiler flags were missing in some
611 makefiles
612 - fix for building with bison 3.0 (#202)
613 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
614 on the process's main thread
615 - fixed build error on newer MinGW
616 - support building with older jack versions

620 in order to get rid of warnings from automake 1.14
621
622 * general changes:
623 - Refactoring: moved the independent code from
624 the Gigasampler format engine to base classes
625 - command line option '--profile' is currently disabled, since the
626 respective profiling code is currently broken
627 - Introduced support for optional environment variable
628 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
629 where the sampler shall look for instrument editor plugins
630 (patch by Luis Garrido, slightly modified).
631 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
632 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
633 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
634 note (in this implementation of the sampler its simply hard routed to
635 the 1st effect send of the sampler channel, no matter what the actual
636 effect type is)
637 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
638 note (in this implementation of the sampler its simply hard routed to
639 the 2nd effect send of the sampler channel, no matter what the actual
640 effect type is)
641 - implemented support for internal LADSPA effects
642 - raised limit of program change queue from 100 to 512
643 (as suggested by Alex Stone)
644 - implemented sine LFO, pulse LFO and saw LFO
645 - experimental support for per voice equalization
646 - added command line option --exec-after-init
647 - Introduced new C++ API method:
648 EngineChannel::InstrumentFileName(int index)
649 allowing to retrieve the whole list of files used for the loaded
650 instrument on an engine channel (a.k.a. part). Some GigaStudio
651 instruments for example are splitted over several files like
652 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
653 - Added new C++ API method Sampler::GetGlobalMaxVoices().
654 - Added new C++ API method Sampler::GetGlobalMaxStreams().
655 - Added new C++ API method Sampler::SetGlobalMaxVoices().
656 - Added new C++ API method Sampler::SetGlobalMaxStreams().
657 - Various "const" and "restrict" optimizations.
658 - all engines: add pan CC value to instrument pan parameter before
659 applying panning, instead of using two separate pan functions in
660 series (#182)
661 - added a lock guard class for exception safe mutex handling and
662 used it everywhere appropriate
663 - Immediately apply scale tuning changes to active voices.
664 - Exposed scale tuning to C++ API (along to the already existing standard
665 SysEx way).
666 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
667 and broken for ppc64. (Seq_cst loads and stores are actually not
668 used in LS, so the bug wasn't noticable.)
669 - lsatomic.h: added ARMv7 support
670 - Added support for multiple MIDI input ports per sampler channel (and
671 added various new C++ methods for this new feature / design change, old
672 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
673 as deprecated but are still there and should provide full behavior
674 backward compatibility).
675 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
676 unsafe and caused compilation error with clang 2.x).
677 - Bugfix: only process the latest MIDI program change event.
678 - Introducing the LSCP shell, which provides convenient control of the
679 sampler from the command line by providing LSCP aware features.
680 - VirtualMidiDevice: Added support for program change.
681 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
682 - VirtualMidiDevice: Added support for pitch bend.
683 - Aftertouch: extended API to explicitly handle channel pressure and
684 polyphonic key pressure events (so far polyphonic pressure was not
685 supported at all, and channel pressure was rerouted as CC128 but not
686 used so far).
687 - Added initial support for real-time instrument scripts. The script VM
688 code is shared by all sampler engine implemementations, however only the
689 gig file format currently provides support for storing instrument scripts
690 (as LinuxSampler extension to the original GigaStudio 4 format).
691
692 * Gigasampler format engine:
693 - implemented the "round robin keyboard" dimension

697 key
698 - bugfix: pitch LFO controller "internal+aftertouch" was broken
699 - bugfix: filter keyboard tracking was broken
700 - filter performance fix (an unnecessary copy was made of the
701 filter parameters in each sub fragment)
702 - handle special case when pan parameter in gig file has max or
703 min value
704 - Exclusive Groups: don't ever stop voices of the same note,
705 doesn't sound naturally with a drumkit
706 - fixed EG1 modulation when attack or release is zero
707 - Fixed support for 'aftertouch' attenuation controller.
708 - Fixed crash that happened with velocity split sounds under certain
709 conditions (see also previous commit on libgig).
710 - fixed behaviour of filter LFO
711
712 * SFZ format engine:

742 - added support for loop_mode=one_shot
743 - fixed playback of 16 bit wav files on big endian CPUs
744 - added support for Ogg Vorbis sample files
745 - use loop markers from sample file if loop_start and loop_end are
746 not set in sfz file
747 - implemeted filters. Filter types: lowpass, bandpass, bandreject
748 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
749 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
750 cutoff_cc, cutoff_chanaft.
751 - bugfix: zero ampeg_sustain didn't work

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

1015 - Added support for moving cursor left/right with arrow keys.
1016 - Added support for built-in LSCP reference documentation, which will
1017 automatically show the relevant LSCP reference section on screen as soon

1067 - Pass/preserve polyphonic variable data from respective "note" event
1068 handler to "release" event handler.
1069 - Fixed crash when using built-in script function "by_marks()".
1070

1075 channel to a different engine type
1076 - fixed crash when deleting a sampler channel or changing engine
1077 type while an instrument load was in progress
1078 - bugfix: playing a note while changing the instrument could cause
1079 a crash, or give "Handing back unknown region" error messages
1080 - bugfix: calling SET VOICES (which Fantasia does on start and
1081 refresh) could cause instruments to be unloaded
1082 - Mac OS X: fixed name collision of enum in EffectControl and
1083 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1084 - Mac OS X: fixed hanging threads
1085 - Windows: disabled the previous thread fix on non-Mac systems, as
1086 it caused hanging threads on Windows

1088 after MIDI/audio device creation failure
1089 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1090 instruments were uselessly precached with zero samples, however it still
1091 took the full preloading time and on 1st program change the respective
1092 instrument was completely reloaded again.
1093 - fixed handling of rapid bank select and program change messages
1094 sent to the same sampler channel (patch from the Open Octave
1095 project, slightly adjusted)

1114 crashes and noise on such transitions).
1115 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1116 (fixes #208)
1117 - Fixed bug in LSCP grammar definition which caused a statement like
1118 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1119 practically irrelevant, however it caused problems with the new LSCP
1120 shell's auto completion feature).
1121 - Fixed MIDI program change messages being ignored if quickly executed
1122 after each other (fixes #231).
1123
1124 Version 1.0.0 (31 July 2009)
1125
1126 * packaging changes:
1127 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1128 causing e.g. the libgig test to fail when
1129 "./configure --disable-jack-driver" was used
1130 (patch by Alexis Ballier)
1131 - fixed compilation with gcc 4.3
1132 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1137 - minor fix in configure for mmsystem.h detection on MinGW
1138 - Windows: look for editor plugins and Fantasia using base
1139 directory of liblinuxsampler dll (look in the same directory and one
1140 directory above)
1141 - configure script fix: removed unconditional use of SSE
1142 - fixed building with sqlite installed in a non-standard directory
1143 - when cross-compiling, don't try to create instruments.db
1144 - fix for new mingw-w64 version, which has usleep
1145
1146 * general changes:
1147 - bugfix: on some POSIX systems instrument editor plugins refused to
1148 load as we used a non-portable Linux specific struct field
1149 (fixes bug #70, patch by Ronald Baljeu)
1150 - fixed endless loop which occured when loading an instrument editor
1151 plugin DLL on Windows systems failed
1152 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1153 - optimized the SynchronizedConfig class so it doesn't wait
1154 unnecessarily long after an update
1155 - added support for notifying instrument editors on note-on / note-off
1156 events (e.g. to highlight the pressed keys on the virtual keyboard
1157 of gigedit)
1158 - added support for triggering notes by instrument editors (see above)
1159 - be verbose on DLL load errors (on Linux)
1160 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1161 is only used by very few systems, most pick the int math
1162 implementation, which is usually faster)
1163 - fixes for audio drivers with varying buffer sizes
1164 - experimental support for running LinuxSampler as a DSSI, LV2 and
1165 VST plugin
1166 - notification events for stream/voice count statistics are now sent
1167 only when there are actual changes
1168 - added memory ordering constraints to improve stability on
1169 multi-core and multi-cpu systems
1170 - maximum voices and disk streams can now be altered at runtime
1171 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1172 - automatic stacktrace mechanism is now turned off by default and can
1173 be switched on by command line option "--stacktrace" (the automatic
1174 stacktrace mechanism seems to be broken on most systems at the moment)
1175 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1176 a pointer to the launched InstrumentEditor object
1177 - added optional 3rd party user data parameter for following
1178 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1179 InstrumentEditor::Launch(),
1180 InstrumentManager::LaunchInstrumentEditor()
1181 - theoretical fix: made SynchronizedConfig follow C++0x memory
1182 model more strictly
1183 - fixes for using large audio device buffers
1184 - Windows: add the installation directory to the DLL search path
1185 when loading an editor plugin (solves problems with VST and
1186 gigedit on systems with other GTK versions installed)
1187 - updated linuxsampler man page
1188
1189 * audio driver:
1190 - removed the nonsense audio channel constraint (which was hard coded to
1191 max. 100 audio channels) for most audio drivers
1192 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1193 opposed to the LSCP specs
1194 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1195 reflected the wrong value
1196 - fixed a memory management bug in ASIO driver
1197 - Makefile fix: JACK_CFLAGS wasn't used
1198 - JACK: use jack_client_open instead of the deprecated
1199 jack_client_new
1200 - added (experimental) CoreAudio driver
1201 - applied old fixes to the ASIO driver that were included in the
1202 previous binary release but accidentally never committed to CVS
1203 (fixes #117)
1204 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1205 win64)
1206 - VST: added support for sample rate and buffer size changes
1207 - VST: close editor (Fantasia) when the VST is removed
1208 - VST: avoid opening Fantasia more than once for each VST instance
1209 - VST: export main function as "main" on Linux too (fix for
1210 energyXT)
1211 - VST: changed number of output channels from one stereo to 16
1212 stereo
1213 - added channel routing, fxsends and midi maps to the settings
1214 stored in the plugin state
1215 - performance optimization of AudioChannel::MixTo() and
1216 AudioChannel::CopyTo() methods using GCC vector exensions
1217 (if available)
1218 - ASIO fixes: avoid initializing the device twice, avoid throwing
1219 exception when getting parameters from a disconnected device
1220
1221 * MIDI driver:
1222 - added JACK MIDI driver
1223 - dispatch bank select as ordinary CC as well, the user might seriously
1224 want to (mis)use it for some purpose ("fixed" in all current MIDI
1225 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1226 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1227 CoreMidi or AU
1228 - fixed mingw-w64 compilation error in MME driver
1229 - made program change handling in MIDI thread real-time safe by
1230 moving the logic to a non-RT thread
1231 - fixed minor memory leak in ALSA driver
1232
1233 * instruments database:
1234 - avoid time consuming samples scanning when adding instruments
1235 to the instruments database
1236 - added support for handling lost files in the instruments database
1237 - Implemented option for adding instruments in separate directories
1238 in the instruments database
1239 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1240 - work-around for missing fnmatch function on Windows to make
1241 instrument database compilable
1242 - added instrument database support on Windows
1243 works with both standalone mode and VST plugin.
1244 the instruments DB file is located in
1245 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1246 databases for each windows user
1247 if no DB is present it automatically creates the .linuxsampler subdir
1248 and then creates an empty DB
1249 - fixed recursive import, which was broken on Windows
1250
1251 * Gigasampler format engine:
1252 - fixed a memory leak that could happen when a channel was deleted
1253 while notes were playing
1254 - made it possible to load an instrument even if the audio thread
1255 isn't running
1256 - added partial support for the "Controller Triggered" MIDI rule,
1257 enough for piano gigs with pedal noise samples
1258 - minor fix: only mark FX sends as being modified if really the
1259 respective FX send MIDI controller was used
1260 - added support for GM global device volume SysEx message
1261 (can be selected at compile time to either apply globally to the
1262 whole sampler [default] or only to the sampler channels that are
1263 connected to the respective MIDI input port the SysEx message arrived
1264 on)
1265 - bugfix: notes triggered at position 0 in the audio buffer were
1266 sometimes wrongly killed in the same buffer, causing no sound to
1267 be played
1268 - added support for chromatic / drumkit mode Roland GS Sysex message
1269 which is usally used to switch a part between chromatic sounds and
1270 drumkit sounds (as opposed to their common default setting of MIDI
1271 part 10 being a drumkit part and all other ones chromatic parts), in
1272 LS however one can switch between the first 16 MIDI instrument maps
1273 defined for the sampler
1274 - made it possible to create multiple sample channels even if the
1275 audio thread isn't running
1276 - fixed crash when removing channel with active voices (#116)
1277 - bugfix: on sample reference changes (instrument editor), only
1278 un-cache the respective sample if it's really not used by any
1279 sampler engine anymore
1280 - re-cache samples in case they were changed by an instrument editor,
1281 e.g. when a sample was added while playing (#82)
1282 - fixed hanging notes which occured when note-off event had the exact
1283 same time stamp as the voice's note-on event and occured both in the
1284 same audio fragment cycle (fixes bug #112)
1285 - added support for the "fine tune" and "pitch bend range"
1286 instrument-level gig parameters
1287 - fixed minor artifacts in pitch bend handling
1288 - added support for GS Reset SysEx message
1289 - allow gig files to use unlimited downward pitch shifting
1290 - added a limit check for upward pitch shifting
1291 - bugfix: sometimes, when playing a note twice fast, the second
1292 note was silent
1293 - fixed crash happening when a pitch bend event arrived at the
1294 same time a new instrument was loading
1295
1296 * LSCP server:
1297 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1298 react on MIDI data arriving on certain sampler channels (so far only
1299 Note-On and Note-Off events are sent via this LSCP event)
1300 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1301 react on MIDI data arriving on certain MIDI input devices (so far only
1302 Note-On and Note-Off events are sent via this LSCP event)
1303 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1304 SET DB_INSTRUMENT FILE_PATH
1305 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1306 frontends to send MIDI messages to specific sampler channel
1307 - added two additional fields to GET FILE INSTRUMENT INFO command -
1308 KEY_BINDINGS and KEYSWITCH_BINDINGS
1309 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1310 was incorrect
1311 - Optimized the retrieval of the MIDI instrument mappings
1312 - added new LSCP command "SET VOICES" to globally alter the maximum
1313 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1314 be triggered respectively
1315 - added new LSCP command "SET STREAMS" to globally alter the maximum
1316 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1317 which will be triggered respectively
1318 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1319 a gigedit file dialog is opened)
1320 - close all connections when LSCPServer is deleted
1321 - hard close of all sockets on exit
1322 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1323 driver
1324
1325 * Bug fixes:
1326 - fixed a crash which occurs when removing a sampler channel waiting
1327 to start instrument loading after another channel
1328 - fixed a crash which occurs when removing a sampler channel with
1329 instrument loading in progress (bug #113)
1330 - fixed termination caused by uncaught exception when adding MIDI
1331 instrument with PERSISTENT load mode
1332 - fixed possible iterator invalidations when resetting the sampler
1333 - fixed memory leaks when issuing the following LSCP commands:
1334 GET AUDIO_OUTPUT_DRIVER INFO
1335 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1336 GET MIDI_INPUT_DRIVER INFO
1337 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1338 - fixed possible compilation error when sqlite is not present
1339 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1340 - fixed crash when changing the audio output device of a sampler
1341 channel with loaded instrument and start playing notes
1342 - fixed endless loop in Engine::SuspendAll() (bug #120)
1343 - fixed a low-level atomic load function that was broken on 64-bit
1344 PowerPC, which probably could cause crashes on that platform
1345 - fixed a memory management error which could cause a crash when a
1346 plugin was unloaded
1347 - bugfix: two private structs had the same name, which could cause
1348 problems if the linker chose the wrong constructor
1349 - fixed low-level ConditionServer usage bug that caused lockups on
1350 Windows
1351
1352
1353 Version 0.5.1 (6 December 2007)
1354
1355 * packaging changes:
1356 - added autoconf checks for pthread library
1357 - added autoconf check for pthread bug found on certain NPTL-enabled
1358 glibc versions (see Gentoo bug report #194076)
1359 - added autoconf checks for MS Windows
1360
1361 * general changes:
1362 - bugfix: the thread used by an editor plugin didn't die when the
1363 editor closed
1364 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1365 out all the space. operator--() did not apply size_mask after
1366 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1367 order to avoid problems with the _NonVolatileReader functions.
1368 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1369 GetWriteSpace(). Since this function is currently only used in
1370 the stream's qsort() compare function, it didn't trigger any
1371 bugs.
1372 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1373 24bit mode too. Faster method to read 24bit words on little
1374 endian machines (x86): replaced 3 byte reads + shifts with a 1
1375 unaligned 32bit read and shift
1376 - experimental support for MS Windows (MIDI input via MME, AUDIO
1377 output via ASIO)
1378 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1379 - support for monitoring the total number of active disk streams
1380 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1381 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1382
1383 * AUDIO driver:
1384 - added Windows ASIO low latency audio driver
1385
1386 * MIDI driver:
1387 - added MME Windows MIDI driver
1388
1389 * LSCP server:
1390 - added support for Windows style path / filenames, however with
1391 forward slash path separators instead of backslash
1392 (i.e. "C:/foo/bar.gig")
1393 - allow naughty liblscp to send non-string device parameters within
1394 apostrophes as well
1395 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1396 "LIST FILE INSTRUMENTS <file>" and
1397 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1398 about an arbitrary instrument file on the system where the sampler is
1399 running on
1400
1401 Version 0.5.0 (15 October 2007)
1402
1403 * packaging changes:
1404 - config.h is not going to be installed along with liblinuxsampler's
1405 API header files anymore
1406 - only the API relevant header (and source) files will be exported to
1407 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1408 - added completely new XCode project files for Mac OSX which is now
1409 capable to execute our autoconf environment, thus no need anymore
1410 to maintain the compile time configuration file (osx/version.h) for
1411 OSX manually (patch by Toshi Nagata)
1412 - fixed buggy boolean --enable-foo / --disable-foo configure script
1413 parameters
1414 - global.h now only covers global definitions that are needed for the
1415 C++ API header files, all implementation internal global definitions
1416 are now in global_private.h
1417 - atomic.h is not exposed to the C++ API anymore
1418 - no need to include config.h anymore for using LS's API header files
1419 - fixed warnings in API doc generation
1420
1421 * general changes:
1422 - replaced the old, confusing MIDI program change mechanism by a
1423 flexible MIDI instrument mapper which allows to map arbitrary
1424 (MIDI bank, MIDI program) pairs with arbitrary
1425 (engine type, instrument file, file index) triplets which will be
1426 loaded on the respective channel when such MIDI program change
1427 messages arrive, beside that, each entry allows to define a life-time
1428 strategy for the instrument, so the user can define whether the
1429 instrument should i.e. be permanently loaded (to be able to switch
1430 quickly among sounds) or i.e. loaded just on demand when the
1431 respective program change arrives (to safe RAM space), as well as a
1432 global volume factor for each entry, so the user can adjust the volume
1433 dynamic of his mapped instrument collection without having to modify
1434 the instrument files, also one can manage arbitrary amount of such
1435 MIDI instrument maps and assign each sampler channel individually
1436 a certain map, so that i.e. separation of normal instruments and
1437 drumkits is possible
1438 - new notification events for tracking changes to audio/MIDI devices,
1439 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1440 - sampler was limited to load max. 200 instruments in the background
1441 due to a constant size RingBuffer FIFO which is now replaced by a
1442 dynamic (unlimited) size std::list FIFO
1443 - added FX sends, these allow to route audio signals to arbitrary audio
1444 output channels for being processed by external effect processors
1445 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1446 controllers
1447 - global (sampler wide) volume can now be controlled at runtime
1448 - Implemented new, improved notification system
1449 - fixed compilation errors regarding OSX
1450 (patch by Toshi Nagata)
1451 - implemented instruments database
1452 - added support for escape sequences to the instruments database
1453 - added highly experimental support for on-the-fly instrument editing
1454 within the sampler's process (by using instrument editor plugins),
1455 you'll notice the new "Registered instrument editors:" message on
1456 startup, added a new LSCP command:
1457 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1458 to spawn a matching instrument editor for the instrument on the
1459 given sampler channel, the plugin path can be overridden at compile
1460 time with ./configure --enable-plugin-dir=/some/dir
1461 - added experimental code for synchronizing instrument editors hosted
1462 in the sampler's process to safely edit instruments while playing
1463 without a crash (hopefully) by either suspending single regions
1464 wherever possible or if unavoidable whole engine(s)
1465 - fixed several issues in fundamental "Thread" class: set scheduling
1466 policy and priority on thread level, set a minimum stack size for
1467 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1468 threads simply inherited properties of starting thread instead of
1469 setting their own policy and priority
1470 - minor fix in our automatic stack trace mechanism on crashes, the
1471 main process did not wait for the stack trace process to finish
1472 its output
1473 - fixed some minor memory leaks
1474 - reenabled assembly features support, at the moment only for
1475 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1476 - minor assembly fix in x86 features detection (don't use the PIC
1477 register, to avoid relocations in the text segment at runtime)
1478 - POSIX callback functions of Thread.h are hidden
1479
1480 * MIDI driver:
1481 - dispatch bank select (MSB and LSB) messages
1482
1483 * audio driver:
1484 - the ALSA audio output driver parameters now reflect the correct
1485 parameter value ranges for the respective selected sound card
1486 (patch by Till Wimmer, a bit fixed and extended)
1487
1488 * Gigasampler format engine:
1489 - if a filter is used and EG2 finishes before EG1, let the voice
1490 die when EG2 has finished (this fixes a problem with clicks and
1491 voice starvation for some gigs)
1492 - playback is no longer disabled during instrument loading
1493 - all notes playing on a channel that changes its instrument keep
1494 playing with the old instrument until they get a note off
1495 command
1496 - EG fix: a release value of zero could cause noises or crash
1497 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1498 - EG fine tuning: when attack is zero the EG starts at a level
1499 above max sustain level, which means that there is a decay phase
1500 even if sustain is 100%
1501 - more EG fixes: the level could sometimes go below zero and cause
1502 noises or crashes
1503 - minor fix of EGDecay (patch by Toshi Nagata)
1504 - fixed compiler error when --enable-override-filter-type was
1505 supplied to the configure script (fixes #46)
1506 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1507 instead of a fix value
1508 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1509 127 (solo mode) only kill voices if the respective mode really
1510 changed
1511
1512 * LSCP server:
1513 - fixed compile time error for old Bison versions
1514 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1515 - parser now supports extended ASCII character set
1516 (up to ASCII code 255, i.e. includes now umlauts and accents)
1517 - filename arguments in LSCP commands now allow to use escape
1518 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1519 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1520 code value like \xf2) (fixes bug #24)
1521 - the following LSCP commands now also support escape sequences for at
1522 least one of their text-based parameters (i.e. name, description):
1523 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1524 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1525 "SET DB_INSTRUMENT_DIRECTORY NAME",
1526 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1527 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1528 "FIND DB_INSTRUMENT_DIRECTORIES"
1529 - returns verbose syntax errors (line and column where syntax error
1530 occured, the unexpected character and the actually expected, possible
1531 character(s), the latter only if less than 5 possibilities)
1532 - made sure that LSCP syntax is not affected by gigedit locale
1533 settings
1534 - bugfix regarding strings parameter lists: all comma separated lists
1535 of strings were treated as being one string containing commas
1536 (fixes #57)
1537
1538 * Bug fixes:
1539 - fixed crash occurring on certain LSCP scripts (Bug 39)
1540 - another thread safety fix for lscp "load engine" and "set
1541 channel audio output device"
1542 - fixed a crash which occurs when reassigning the same engine
1543 on a sampler channel with connected MIDI device
1544 - fixed a crash which occurs when changing the number of ports of a MIDI
1545 device connected to a sampler channel to number less then or equal
1546 to the index of the port to which the sampler channel is connected.
1547 - The previous bindings were not been disconnected when altering
1548 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1549 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1550 - The active stream/voice count statistic was incorrect.
1551 - notification events were not been sent for some sampler
1552 channel changes
1553 - added default min and max values to restrict the number of allowed
1554 audio output channels and MIDI input ports
1555 - the connection to the PCM interface is now closed when destroying
1556 an audio output device
1557 - files with slash in their path or filename could not be loaded
1558
1559 * test cases:
1560 - updated and fixed (haven't been touched in a while)
1561
1562 Version 0.4.0 (24 November 2006)
1563
1564 * packaging changes:
1565 - changed deprecated copyright attribute to license; added ldconfig
1566 to post-(un)install steps; added devel package for liblinuxsampler;
1567 to linuxsampler.spec (RPM)
1568 - install necessary development header files for allowing 3rd party
1569 applications to link against liblinuxsampler
1570 - liblinuxsampler's API documentation can be generated with 'make docs'
1571 (Doxygen required)
1572 - added benchmark to automatically detect the best triangle LFO
1573 implementation (currently either an integer math solution or a
1574 di-harmonic approximation), automatic detection can be overriden
1575 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1576 configure script argument though (mandatory for cross-compilation)
1577 - do not automatically pick optimized gcc flags if the user already
1578 provided some on his own (as CXXFLAGS)
1579 - added compile time option to disable processing of All-Notes-Off MIDI
1580 messages
1581 - added compile time options to allow disabling the various audio and
1582 MIDI drivers
1583 - fixed automatic GCC CPU switch detection on PPC
1584 (patch by Ebrahim Mayat)
1585
1586 * Gigasampler format engine:
1587 - extensive synthesis optimization
1588 (reimplementation of EGs and LFO(s), removed synthesis parameter
1589 prerendering and the synthesis parameter matrix in general, splitting
1590 each audio fragment into subfragments now where each subfragment uses
1591 constant pitch and filter coefficients. The volume coefficient is
1592 linearly interpolated inside a subfragment, unless
1593 --disable-interpolate-volume is set.)
1594 - fine tuning of the EG modulation parameters
1595 - improved filter cutoff calculation by adding support for the
1596 following gig parameters: Cutoff freq (used when no cutoff
1597 controller is defined), Control invert, Minimum cutoff, Velocity
1598 curve and Velocity range. The keyboard tracking now scales
1599 cutoff frequency instead of resonance.
1600 - added support for gig parameter Resonance.
1601 - fixed bug in sysex handling (patch by Juan Linietsky)
1602 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1603 which can be overridden with --enable-global-attenuation
1604 - EG fixes: made the length of "attack hold" stage more
1605 accurate. Release stage can now start before attack stage
1606 ends. Cancel release didn't work when sustain was zero. Attack
1607 time now has a minimal value to prevent clicks.
1608 - fixed pitch changes larger than one octave
1609 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1610 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1611 all modes can be altered via standard GM messages, that is CC5 for
1612 altering portamento time, CC65 for enabling / disabling portamento
1613 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1614 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1615 parameter) and crossfade
1616 - added support for the "attenuation controller threshold" gig
1617 parameter
1618 - added smoothing of volume changes caused by control change
1619 messages
1620 - sample loop parameters are now taken from the DimensionRegion
1621 instead of the wave chunk
1622 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1623 not equal to a power of two
1624 - reimplementation of the filter algorithm. The new filter is more
1625 accurate and supports all gig filter types, including bandreject
1626 and lowpass turbo.
1627 - real support for 24 bit samples - samples are not truncated to
1628 16 bits anymore
1629 - support for aftertouch (channel pressure, not polyphonic
1630 aftertouch)
1631 - LFO1 behaviour fixed (dampening from max volume instead of
1632 amplifying from 0)
1633
1634 * LSCP server:
1635 - fixed application exit on broken pipe error (fixes bug #20)
1636 - fixed the notification messages delay due to lack of
1637 network activity (fixes bug #26)
1638 - fixed parser bug which occured on space(s) within device parameters
1639 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1640
1641 * audio driver:
1642 - added aRts audio output driver (by no means RT safe)
1643
1644 * MIDI driver:
1645 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1646 messages several times instead of once
1647 - API extension for MIDI drivers which already supply exact time stamps
1648 for events (i.e. for offline rendering based MIDI drivers)
1649 - added checks for bad MIDI data
1650
1651 * linuxsampler application:
1652 - show available sampler engine types on startup
1653
1654 * general changes:
1655 - support for muting sampler channels and solo mode of the same, two new
1656 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1657 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1658 introduced for this, the behavior is the same like on a mixer console
1659 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1660 --enable-process-muted-channels which can be used to enable the
1661 processing of muted channels.
1662 - support for sostenuto pedal
1663 - support for monitoring the total number of active voices
1664 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1665 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1666 - fixed some memory management errors
1667 - fixed some concurrency problems that could lead to crashes when
1668 LSCP commands were executed
1669 - fixed crash when instrument loading failed previously on the same
1670 sampler channel (fixes bug #36)
1671
1672 Version 0.3.3 (15 July 2005)
1673
1674 * packaging changes:
1675 - fixed compilation with gcc 4.0
1676
1677 * Gigasampler format engine:
1678 - LFO preprocessing was performed even though the respective LFO was
1679 disabled by the instrument patch (minor efficiency fix)
1680 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1681 for volume ramp downs in the same fragment (needed for current voice
1682 stealing implementation) then simply inform the user with a warning
1683 about possible click sounds and reduce the volume ramp down
1684 appropriately instead of cancelling the audio device connection
1685
1686 Version 0.3.2 (24 June 2005)
1687
1688 * packaging changes:
1689 - updated autotools build files to compile on OS X
1690 (conditional compilation of CoreMIDI and MidiShare drivers)
1691 - hand-crafted assembly optimization code can be disabled with
1692 './configure --disable-asm' (definitely not recommended)
1693 - fixed 'make dist' rule to include all necessary files
1694 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1695 (due to 'dist-bzip2' automake option)
1696
1697 * Gigasampler format engine:
1698 - support for the gig parameters for "release velocity response" curves
1699 - fine tuning of the EGADSR envelope
1700 - volume of release triggered samples now depends on note-on velocity,
1701 note length and gig parameter "release trigger decay" instead of
1702 note-off velocity.
1703 - revised voice stealing
1704 (fixes crash and endless loop caused by voice stealing)
1705 - don't reset scale tuning on instrument or audio output device change
1706 - handle key group conflicts right at the beginning of each fragment
1707 instead of when the respective voice is actually launched
1708 (fixes undefined behavior if stolen voices belonged to a key group -
1709 this case was followed by a "killed voice survived" error message)
1710 - fixed minor issue with null/silence samples
1711 (those stole voices even though they don't need a voice at all which
1712 resulted in "voice stealing didn't work out" messages)
1713 - don't reset volume, pan, pitch and MIDI controller values on
1714 instrument or audio output device change
1715
1716 * LSCP server:
1717 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1718 - fixed LSCP event "CHANNEL_INFO" notification
1719 (e.g. did not notify on volume changes or MIDI program change events)
1720
1721 * linuxsampler application:
1722 - added command line parameters --lscp-addr and --lscp-port to override
1723 default IP address and port of LSCP server
1724
1725 Version 0.3.1 (24 May 2005)
1726
1727 * initial release
