NKSP: Implemented common real number math functions.

* Added built-in real number functions "round()", "ceil()", "floor()",
  "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
  "cos()", "tan()", "asin()", "acos()", "atan()".

* Added built-in script real number constant "~NI_MATH_PI".

* Added built-in script real number constant "~NI_MATH_E".

* Added NKSP test cases for built-in functions "round()", "ceil()",
  "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
  "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".

* Bumped version (2.1.1.svn14).

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

440 available for gig format engine).
441 - Added built-in script constant "$NKSP_LINEAR".
442 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
443 - Implemented built-in script function "change_vol_curve()".
444 - Implemented built-in script function "change_tune_curve()".
445 - built-in "play_note()" function now supports a sample playback start
446 offset with argument 3, where special value -1 means to use the regular
447 sample offset as defined by the instrument file.
448 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
449 - Built-in variable $EVENT_NOTE is now a read-only variable.
450 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
451 - built-in "play_note()" function now accepts -2 for its fourth argument
452 (note duration) which means the life time of the note shall be sticked
453 to the requested note number of argument 1.
454 - Fix: built-in "play_note()" function now returns 0 as result value if
455 -1 was passed for its fourth argument (note duration) and the respective
456 parent note is already gone.
457 - Implemented built-in script function "change_play_pos()".
458 - NKSP language: Added support for user declared const array variables.
459 - NKSP language: Raise parser warning if array variable is accessed with
460 an index that exceeds the array's size.
461 - NKSP language fix: Unknown characters were not handled correctly.
462 - NKSP language: Added support for "synchronized .. end synchronized"
463 code blocks.
464 - Implemented built-in script function "abort()" which allows to abort
465 another script handler by passing its callback ID.
466 - Fixed potential memory access bug and potential undefined behavior of
467 "init" event handlers.
468 - Print a time stamp along to each call of built-in function "message()".
469 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
470 to retrieve all code blocks filtered out by the preprocessor.
471 - Added built-in script function "fork()".
472 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
473 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
474 - Fixed potential crash when accessing dynamic built-in array variables.
475 - Added built-in script function "callback_status()".
476 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
477 - Added built-in constant $CALLBACK_STATUS_QUEUE.
478 - Added built-in constant $CALLBACK_STATUS_RUNNING.
479 - Removed max. value limitation of built-in functions "change_attack()",
480 "change_decay()" and "change_release()" to i.e. allow passing 2000000
481 for doubling the respective time.
482 - NKSP script editor syntax highlighting API: Fixed app termination due
483 to a lexer start condition stack underrun.
484 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
485 USE_CODE_IF_NOT() preprocessor statements.
486 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
487 can be set to disable all subsequent built-in "message()" function calls
488 on preprocessor level.
489 - Implemented built-in script function "change_sustain()".
490 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
491 to avoid the editor app to crash on ill-formed text input.
492 - Added built-in script function "change_pan_time()".
493 - Added built-in script function "change_pan_curve()".

498 - Added built-in script function "change_cutoff_lfo_depth()".
499 - Added built-in script function "change_cutoff_lfo_freq()".
501 * Instruments DB:
502 - Fixed memory access bug of general DB access code which lead to
503 undefined behavior.
504 - Cleanup of instruments DB file creation and opening code.
505 - The instrument DB path of linuxsampler's --create-instruments-db argument
506 is now optional, if it is missing, then a default location is used.
507 - Added support for scanning SFZ (.sfz) files.
508 - Added support for scanning Sound Font (.sf2) files.
509 - Fixed undefined DB transaction behavior.

521 - another "make dist" fix, for the LV2 plugin
522 - made --enable-pthread-testcancel default on Mac OS X
523 - minor Makefile fix for building lscpparser when build and source
524 directories are separate
525 - Mac OS X: made it possible to specify plugin installation dir to

527 - Mac OS X: Makefile fix for the install-strip target
528 - fixed compilation with gcc 4.7
529 - fixed configure script error with old autoconf versions
530 - lsatomic.h: use gcc provided atomic functions if building with
531 gcc 4.7 and C++11
532 - modernized configure script
533 - fixed linkage error when building with
534 LDFLAGS="-Wl,--no-undefined" (#190)

543 on the process's main thread
544 - fixed build error on newer MinGW

547 - enabled automake 'subdir-objects' option and moved external
548 source references (vst, au, asio) from makefiles to cpp files,
549 in order to get rid of warnings from automake 1.14
551 * general changes:
552 - Refactoring: moved the independent code from
553 the Gigasampler format engine to base classes
554 - command line option '--profile' is currently disabled, since the
555 respective profiling code is currently broken
556 - Introduced support for optional environment variable
557 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
558 where the sampler shall look for instrument editor plugins
559 (patch by Luis Garrido, slightly modified).
560 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
561 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
562 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
563 note (in this implementation of the sampler its simply hard routed to
564 the 1st effect send of the sampler channel, no matter what the actual
565 effect type is)
566 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
567 note (in this implementation of the sampler its simply hard routed to
568 the 2nd effect send of the sampler channel, no matter what the actual
569 effect type is)
570 - implemented support for internal LADSPA effects
571 - raised limit of program change queue from 100 to 512
572 (as suggested by Alex Stone)
573 - implemented sine LFO, pulse LFO and saw LFO
574 - experimental support for per voice equalization
575 - added command line option --exec-after-init
576 - Introduced new C++ API method:
577 EngineChannel::InstrumentFileName(int index)
578 allowing to retrieve the whole list of files used for the loaded
579 instrument on an engine channel (a.k.a. part). Some GigaStudio
580 instruments for example are splitted over several files like
581 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
582 - Added new C++ API method Sampler::GetGlobalMaxVoices().
583 - Added new C++ API method Sampler::GetGlobalMaxStreams().
584 - Added new C++ API method Sampler::SetGlobalMaxVoices().
585 - Added new C++ API method Sampler::SetGlobalMaxStreams().
586 - Various "const" and "restrict" optimizations.
587 - all engines: add pan CC value to instrument pan parameter before
588 applying panning, instead of using two separate pan functions in
589 series (#182)
590 - added a lock guard class for exception safe mutex handling and
591 used it everywhere appropriate
592 - Immediately apply scale tuning changes to active voices.
593 - Exposed scale tuning to C++ API (along to the already existing standard
594 SysEx way).
595 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
596 and broken for ppc64. (Seq_cst loads and stores are actually not
597 used in LS, so the bug wasn't noticable.)
598 - lsatomic.h: added ARMv7 support
599 - Added support for multiple MIDI input ports per sampler channel (and
600 added various new C++ methods for this new feature / design change, old
601 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
602 as deprecated but are still there and should provide full behavior
603 backward compatibility).
604 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
605 unsafe and caused compilation error with clang 2.x).
606 - Bugfix: only process the latest MIDI program change event.
607 - Introducing the LSCP shell, which provides convenient control of the
608 sampler from the command line by providing LSCP aware features.
609 - VirtualMidiDevice: Added support for program change.
610 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
611 - VirtualMidiDevice: Added support for pitch bend.
612 - Aftertouch: extended API to explicitly handle channel pressure and
613 polyphonic key pressure events (so far polyphonic pressure was not
614 supported at all, and channel pressure was rerouted as CC128 but not
615 used so far).
616 - Added initial support for real-time instrument scripts. The script VM
617 code is shared by all sampler engine implemementations, however only the
618 gig file format currently provides support for storing instrument scripts
619 (as LinuxSampler extension to the original GigaStudio 4 format).
621 * Gigasampler format engine:
622 - implemented the "round robin keyboard" dimension
623 - fixed round robin and random dimensions for cases when number of
624 dimension zones is not a power of two
625 - made round robin use a counter for each region instead of each
626 key
627 - bugfix: pitch LFO controller "internal+aftertouch" was broken
628 - bugfix: filter keyboard tracking was broken
629 - filter performance fix (an unnecessary copy was made of the
630 filter parameters in each sub fragment)
631 - handle special case when pan parameter in gig file has max or
632 min value
633 - Exclusive Groups: don't ever stop voices of the same note,
634 doesn't sound naturally with a drumkit
635 - fixed EG1 modulation when attack or release is zero
636 - Fixed support for 'aftertouch' attenuation controller.
637 - Fixed crash that happened with velocity split sounds under certain
638 conditions (see also previous commit on libgig).
639 - fixed behaviour of filter LFO
641 * SFZ format engine:
642 - Initial implementation (not usable yet)
643 - added support for v2 multiple stage envelope generators
644 - added a fine-tuned v1 envelope generator instead of using the
645 one from the gig engine
646 - fixed memory leak and memory handling errors
647 - added support for trigger=first, trigger=legato and sw_previous
648 - allow non-numerical key values ("C#4" for example)

650 - fixed error when unloading instrument with same sample used by
651 multiple regions
652 - added some opcode aliases, like loopmode for loop_mode, to be
653 more compatible
654 - added support for trigger=release and rt_decay
655 - added support for off_mode=normal
656 - added support for random, seq_position, seq_length and volume

669 off_mode)
670 - added support for controller triggered regions (on_locc/on_hicc)
671 - added support for loop_mode=one_shot
672 - fixed playback of 16 bit wav files on big endian CPUs
673 - added support for Ogg Vorbis sample files
674 - use loop markers from sample file if loop_start and loop_end are
675 not set in sfz file
676 - implemeted filters. Filter types: lowpass, bandpass, bandreject
677 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
678 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
679 cutoff_cc, cutoff_chanaft.
680 - bugfix: zero ampeg_sustain didn't work

943 be the case in other shells).
944 - Added support for moving cursor left/right with arrow keys.
945 - Added support for built-in LSCP reference documentation, which will

1007 - bugfix: playing a note while changing the instrument could cause
1008 a crash, or give "Handing back unknown region" error messages
1009 - bugfix: calling SET VOICES (which Fantasia does on start and
1010 refresh) could cause instruments to be unloaded
1011 - Mac OS X: fixed name collision of enum in EffectControl and
1012 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp

1015 it caused hanging threads on Windows
1016 - Fixed possible crashes due to corrupted MIDI/audio device list
1017 after MIDI/audio device creation failure
1018 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1019 instruments were uselessly precached with zero samples, however it still
1020 took the full preloading time and on 1st program change the respective
1021 instrument was completely reloaded again.
1022 - fixed handling of rapid bank select and program change messages
1023 sent to the same sampler channel (patch from the Open Octave
1024 project, slightly adjusted)

1043 crashes and noise on such transitions).
1044 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1045 (fixes #208)
1046 - Fixed bug in LSCP grammar definition which caused a statement like
1047 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1048 practically irrelevant, however it caused problems with the new LSCP
1049 shell's auto completion feature).
1050 - Fixed MIDI program change messages being ignored if quickly executed
1051 after each other (fixes #231).
1053 Version 1.0.0 (31 July 2009)
1055 * packaging changes:

1079 - fixed endless loop which occured when loading an instrument editor
1080 plugin DLL on Windows systems failed
1081 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1082 - optimized the SynchronizedConfig class so it doesn't wait
1083 unnecessarily long after an update

1085 events (e.g. to highlight the pressed keys on the virtual keyboard
1086 of gigedit)
1087 - added support for triggering notes by instrument editors (see above)
1088 - be verbose on DLL load errors (on Linux)
1089 - fixed di-harmonic triangle LFO implementation (this LFO implementation

1091 implementation, which is usually faster)
1092 - fixes for audio drivers with varying buffer sizes
1093 - experimental support for running LinuxSampler as a DSSI, LV2 and
1094 VST plugin
1095 - notification events for stream/voice count statistics are now sent

1099 - maximum voices and disk streams can now be altered at runtime
1100 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1101 - automatic stacktrace mechanism is now turned off by default and can
1102 be switched on by command line option "--stacktrace" (the automatic
1103 stacktrace mechanism seems to be broken on most systems at the moment)
1104 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1105 a pointer to the launched InstrumentEditor object
1106 - added optional 3rd party user data parameter for following
1107 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1108 InstrumentEditor::Launch(),
1109 InstrumentManager::LaunchInstrumentEditor()
1110 - theoretical fix: made SynchronizedConfig follow C++0x memory
1111 model more strictly
1112 - fixes for using large audio device buffers
1113 - Windows: add the installation directory to the DLL search path
1114 when loading an editor plugin (solves problems with VST and
1115 gigedit on systems with other GTK versions installed)
1116 - updated linuxsampler man page
1118 * audio driver:
1119 - removed the nonsense audio channel constraint (which was hard coded to
1120 max. 100 audio channels) for most audio drivers
1121 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1122 opposed to the LSCP specs
1123 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1124 reflected the wrong value
1125 - fixed a memory management bug in ASIO driver
1126 - Makefile fix: JACK_CFLAGS wasn't used
1127 - JACK: use jack_client_open instead of the deprecated

1134 win64)
1135 - VST: added support for sample rate and buffer size changes
1136 - VST: close editor (Fantasia) when the VST is removed
1137 - VST: avoid opening Fantasia more than once for each VST instance
1138 - VST: export main function as "main" on Linux too (fix for
1139 energyXT)
1140 - VST: changed number of output channels from one stereo to 16
1141 stereo
1142 - added channel routing, fxsends and midi maps to the settings
1143 stored in the plugin state
1144 - performance optimization of AudioChannel::MixTo() and
1145 AudioChannel::CopyTo() methods using GCC vector exensions
1146 (if available)
1147 - ASIO fixes: avoid initializing the device twice, avoid throwing
1148 exception when getting parameters from a disconnected device
1150 * MIDI driver:
1151 - added JACK MIDI driver
1152 - dispatch bank select as ordinary CC as well, the user might seriously
1153 want to (mis)use it for some purpose ("fixed" in all current MIDI
1154 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1155 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1156 CoreMidi or AU
1157 - fixed mingw-w64 compilation error in MME driver
1158 - made program change handling in MIDI thread real-time safe by
1159 moving the logic to a non-RT thread

1167 in the instruments database
1168 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1169 - work-around for missing fnmatch function on Windows to make
1170 instrument database compilable
1171 - added instrument database support on Windows
1172 works with both standalone mode and VST plugin.
1173 the instruments DB file is located in
1174 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1175 databases for each windows user
1176 if no DB is present it automatically creates the .linuxsampler subdir
1177 and then creates an empty DB
1178 - fixed recursive import, which was broken on Windows
1180 * Gigasampler format engine:
1181 - fixed a memory leak that could happen when a channel was deleted
1182 while notes were playing
1183 - made it possible to load an instrument even if the audio thread
1184 isn't running
1185 - added partial support for the "Controller Triggered" MIDI rule,
1186 enough for piano gigs with pedal noise samples
1187 - minor fix: only mark FX sends as being modified if really the
1188 respective FX send MIDI controller was used
1189 - added support for GM global device volume SysEx message
1190 (can be selected at compile time to either apply globally to the
1191 whole sampler [default] or only to the sampler channels that are
1192 connected to the respective MIDI input port the SysEx message arrived
1193 on)
1194 - bugfix: notes triggered at position 0 in the audio buffer were
1195 sometimes wrongly killed in the same buffer, causing no sound to
1196 be played
1197 - added support for chromatic / drumkit mode Roland GS Sysex message
1198 which is usally used to switch a part between chromatic sounds and
1199 drumkit sounds (as opposed to their common default setting of MIDI
1200 part 10 being a drumkit part and all other ones chromatic parts), in
1201 LS however one can switch between the first 16 MIDI instrument maps
1202 defined for the sampler
1203 - made it possible to create multiple sample channels even if the
1204 audio thread isn't running
1205 - fixed crash when removing channel with active voices (#116)
1206 - bugfix: on sample reference changes (instrument editor), only
1207 un-cache the respective sample if it's really not used by any
1208 sampler engine anymore
1209 - re-cache samples in case they were changed by an instrument editor,
1210 e.g. when a sample was added while playing (#82)
1211 - fixed hanging notes which occured when note-off event had the exact
1212 same time stamp as the voice's note-on event and occured both in the
1213 same audio fragment cycle (fixes bug #112)
1214 - added support for the "fine tune" and "pitch bend range"
1215 instrument-level gig parameters
1216 - fixed minor artifacts in pitch bend handling
1217 - added support for GS Reset SysEx message
1218 - allow gig files to use unlimited downward pitch shifting
1219 - added a limit check for upward pitch shifting
1220 - bugfix: sometimes, when playing a note twice fast, the second
1221 note was silent
1222 - fixed crash happening when a pitch bend event arrived at the
1223 same time a new instrument was loading
1225 * LSCP server:
1226 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1227 react on MIDI data arriving on certain sampler channels (so far only
1228 Note-On and Note-Off events are sent via this LSCP event)
1229 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1230 react on MIDI data arriving on certain MIDI input devices (so far only
1231 Note-On and Note-Off events are sent via this LSCP event)
1232 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1234 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1235 frontends to send MIDI messages to specific sampler channel
1236 - added two additional fields to GET FILE INSTRUMENT INFO command -
1238 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1239 was incorrect
1240 - Optimized the retrieval of the MIDI instrument mappings
1241 - added new LSCP command "SET VOICES" to globally alter the maximum
1242 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1243 be triggered respectively
1244 - added new LSCP command "SET STREAMS" to globally alter the maximum
1245 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1246 which will be triggered respectively
1247 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1248 a gigedit file dialog is opened)
1249 - close all connections when LSCPServer is deleted
1250 - hard close of all sockets on exit
1251 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1252 driver
1254 * Bug fixes:
1255 - fixed a crash which occurs when removing a sampler channel waiting
1256 to start instrument loading after another channel
1257 - fixed a crash which occurs when removing a sampler channel with
1258 instrument loading in progress (bug #113)
1259 - fixed termination caused by uncaught exception when adding MIDI
1260 instrument with PERSISTENT load mode
1261 - fixed possible iterator invalidations when resetting the sampler
1262 - fixed memory leaks when issuing the following LSCP commands:
1267 - fixed possible compilation error when sqlite is not present
1268 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1269 - fixed crash when changing the audio output device of a sampler
1270 channel with loaded instrument and start playing notes
1271 - fixed endless loop in Engine::SuspendAll() (bug #120)
1272 - fixed a low-level atomic load function that was broken on 64-bit
1273 PowerPC, which probably could cause crashes on that platform
1274 - fixed a memory management error which could cause a crash when a
1275 plugin was unloaded
1276 - bugfix: two private structs had the same name, which could cause
1277 problems if the linker chose the wrong constructor
1278 - fixed low-level ConditionServer usage bug that caused lockups on
1279 Windows
1282 Version 0.5.1 (6 December 2007)
1284 * packaging changes:
1285 - added autoconf checks for pthread library
1286 - added autoconf check for pthread bug found on certain NPTL-enabled
1287 glibc versions (see Gentoo bug report #194076)
1288 - added autoconf checks for MS Windows
1290 * general changes:
1291 - bugfix: the thread used by an editor plugin didn't die when the
1292 editor closed
1293 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1294 out all the space. operator--() did not apply size_mask after
1295 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1296 order to avoid problems with the _NonVolatileReader functions.
1297 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1298 GetWriteSpace(). Since this function is currently only used in
1299 the stream's qsort() compare function, it didn't trigger any
1300 bugs.
1301 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1302 24bit mode too. Faster method to read 24bit words on little
1303 endian machines (x86): replaced 3 byte reads + shifts with a 1
1304 unaligned 32bit read and shift
1305 - experimental support for MS Windows (MIDI input via MME, AUDIO
1306 output via ASIO)
1307 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1308 - support for monitoring the total number of active disk streams
1309 (new LSCP commands: GET TOTAL_STREAM_COUNT,

1320 forward slash path separators instead of backslash
1321 (i.e. "C:/foo/bar.gig")
1322 - allow naughty liblscp to send non-string device parameters within
1323 apostrophes as well
1324 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1325 "LIST FILE INSTRUMENTS <file>" and
1326 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1327 about an arbitrary instrument file on the system where the sampler is
1328 running on
1330 Version 0.5.0 (15 October 2007)
1332 * packaging changes:
1333 - config.h is not going to be installed along with liblinuxsampler's
1334 API header files anymore
1335 - only the API relevant header (and source) files will be exported to
1336 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1337 - added completely new XCode project files for Mac OSX which is now
1338 capable to execute our autoconf environment, thus no need anymore
1339 to maintain the compile time configuration file (osx/version.h) for
1340 OSX manually (patch by Toshi Nagata)
1341 - fixed buggy boolean --enable-foo / --disable-foo configure script
1342 parameters
1343 - global.h now only covers global definitions that are needed for the
1344 C++ API header files, all implementation internal global definitions
1345 are now in global_private.h
1346 - atomic.h is not exposed to the C++ API anymore
1347 - no need to include config.h anymore for using LS's API header files
1348 - fixed warnings in API doc generation
1350 * general changes:
1351 - replaced the old, confusing MIDI program change mechanism by a
1352 flexible MIDI instrument mapper which allows to map arbitrary
1353 (MIDI bank, MIDI program) pairs with arbitrary
1354 (engine type, instrument file, file index) triplets which will be
1355 loaded on the respective channel when such MIDI program change
1356 messages arrive, beside that, each entry allows to define a life-time
1357 strategy for the instrument, so the user can define whether the
1358 instrument should i.e. be permanently loaded (to be able to switch
1359 quickly among sounds) or i.e. loaded just on demand when the
1360 respective program change arrives (to safe RAM space), as well as a
1361 global volume factor for each entry, so the user can adjust the volume
1362 dynamic of his mapped instrument collection without having to modify
1363 the instrument files, also one can manage arbitrary amount of such
1364 MIDI instrument maps and assign each sampler channel individually
1365 a certain map, so that i.e. separation of normal instruments and
1366 drumkits is possible
1367 - new notification events for tracking changes to audio/MIDI devices,
1368 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1369 - sampler was limited to load max. 200 instruments in the background
1370 due to a constant size RingBuffer FIFO which is now replaced by a
1371 dynamic (unlimited) size std::list FIFO
1372 - added FX sends, these allow to route audio signals to arbitrary audio
1373 output channels for being processed by external effect processors
1374 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1375 controllers
1376 - global (sampler wide) volume can now be controlled at runtime
1377 - Implemented new, improved notification system
1378 - fixed compilation errors regarding OSX
1379 (patch by Toshi Nagata)
1380 - implemented instruments database
1381 - added support for escape sequences to the instruments database
1382 - added highly experimental support for on-the-fly instrument editing
1383 within the sampler's process (by using instrument editor plugins),
1384 you'll notice the new "Registered instrument editors:" message on
1385 startup, added a new LSCP command:
1386 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1387 to spawn a matching instrument editor for the instrument on the
1388 given sampler channel, the plugin path can be overridden at compile
1389 time with ./configure --enable-plugin-dir=/some/dir
1390 - added experimental code for synchronizing instrument editors hosted
1391 in the sampler's process to safely edit instruments while playing
1392 without a crash (hopefully) by either suspending single regions
1393 wherever possible or if unavoidable whole engine(s)
1394 - fixed several issues in fundamental "Thread" class: set scheduling
1395 policy and priority on thread level, set a minimum stack size for
1396 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1397 threads simply inherited properties of starting thread instead of
1398 setting their own policy and priority
1399 - minor fix in our automatic stack trace mechanism on crashes, the
1400 main process did not wait for the stack trace process to finish
1401 its output
1402 - fixed some minor memory leaks
1403 - reenabled assembly features support, at the moment only for
1404 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1405 - minor assembly fix in x86 features detection (don't use the PIC
1406 register, to avoid relocations in the text segment at runtime)
1407 - POSIX callback functions of Thread.h are hidden
1409 * MIDI driver:
1410 - dispatch bank select (MSB and LSB) messages
1412 * audio driver:
1413 - the ALSA audio output driver parameters now reflect the correct
1414 parameter value ranges for the respective selected sound card
1415 (patch by Till Wimmer, a bit fixed and extended)
1417 * Gigasampler format engine:
1418 - if a filter is used and EG2 finishes before EG1, let the voice
1419 die when EG2 has finished (this fixes a problem with clicks and
1420 voice starvation for some gigs)
1421 - playback is no longer disabled during instrument loading
1422 - all notes playing on a channel that changes its instrument keep
1423 playing with the old instrument until they get a note off
1424 command
1425 - EG fix: a release value of zero could cause noises or crash
1426 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1427 - EG fine tuning: when attack is zero the EG starts at a level
1428 above max sustain level, which means that there is a decay phase
1429 even if sustain is 100%
1430 - more EG fixes: the level could sometimes go below zero and cause
1431 noises or crashes
1432 - minor fix of EGDecay (patch by Toshi Nagata)
1433 - fixed compiler error when --enable-override-filter-type was
1434 supplied to the configure script (fixes #46)
1435 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1436 instead of a fix value
1437 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1438 127 (solo mode) only kill voices if the respective mode really
1439 changed
1441 * LSCP server:
1442 - fixed compile time error for old Bison versions
1443 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1444 - parser now supports extended ASCII character set
1445 (up to ASCII code 255, i.e. includes now umlauts and accents)
1446 - filename arguments in LSCP commands now allow to use escape
1447 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1448 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1449 code value like \xf2) (fixes bug #24)
1450 - the following LSCP commands now also support escape sequences for at
1451 least one of their text-based parameters (i.e. name, description):
1458 - returns verbose syntax errors (line and column where syntax error
1459 occured, the unexpected character and the actually expected, possible
1460 character(s), the latter only if less than 5 possibilities)
1461 - made sure that LSCP syntax is not affected by gigedit locale
1462 settings
1463 - bugfix regarding strings parameter lists: all comma separated lists
1464 of strings were treated as being one string containing commas
1465 (fixes #57)
1467 * Bug fixes:
1468 - fixed crash occurring on certain LSCP scripts (Bug 39)
1469 - another thread safety fix for lscp "load engine" and "set
1470 channel audio output device"
1471 - fixed a crash which occurs when reassigning the same engine
1472 on a sampler channel with connected MIDI device
1473 - fixed a crash which occurs when changing the number of ports of a MIDI
1474 device connected to a sampler channel to number less then or equal
1475 to the index of the port to which the sampler channel is connected.
1476 - The previous bindings were not been disconnected when altering
1477 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1478 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1479 - The active stream/voice count statistic was incorrect.
1480 - notification events were not been sent for some sampler
1481 channel changes
1482 - added default min and max values to restrict the number of allowed
1483 audio output channels and MIDI input ports
1484 - the connection to the PCM interface is now closed when destroying
1485 an audio output device
1486 - files with slash in their path or filename could not be loaded
1488 * test cases:
1489 - updated and fixed (haven't been touched in a while)
1491 Version 0.4.0 (24 November 2006)
1493 * packaging changes:
1494 - changed deprecated copyright attribute to license; added ldconfig
1495 to post-(un)install steps; added devel package for liblinuxsampler;
1496 to linuxsampler.spec (RPM)
1497 - install necessary development header files for allowing 3rd party
1498 applications to link against liblinuxsampler
1499 - liblinuxsampler's API documentation can be generated with 'make docs'
1500 (Doxygen required)
1501 - added benchmark to automatically detect the best triangle LFO
1502 implementation (currently either an integer math solution or a
1503 di-harmonic approximation), automatic detection can be overriden
1504 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1505 configure script argument though (mandatory for cross-compilation)
1506 - do not automatically pick optimized gcc flags if the user already
1507 provided some on his own (as CXXFLAGS)
1508 - added compile time option to disable processing of All-Notes-Off MIDI
1509 messages
1510 - added compile time options to allow disabling the various audio and
1511 MIDI drivers
1512 - fixed automatic GCC CPU switch detection on PPC
1513 (patch by Ebrahim Mayat)
1515 * Gigasampler format engine:
1516 - extensive synthesis optimization
1517 (reimplementation of EGs and LFO(s), removed synthesis parameter
1518 prerendering and the synthesis parameter matrix in general, splitting
1519 each audio fragment into subfragments now where each subfragment uses
1520 constant pitch and filter coefficients. The volume coefficient is
1521 linearly interpolated inside a subfragment, unless
1522 --disable-interpolate-volume is set.)
1523 - fine tuning of the EG modulation parameters
1524 - improved filter cutoff calculation by adding support for the
1525 following gig parameters: Cutoff freq (used when no cutoff
1526 controller is defined), Control invert, Minimum cutoff, Velocity
1527 curve and Velocity range. The keyboard tracking now scales
1528 cutoff frequency instead of resonance.
1529 - added support for gig parameter Resonance.
1530 - fixed bug in sysex handling (patch by Juan Linietsky)
1531 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1532 which can be overridden with --enable-global-attenuation
1533 - EG fixes: made the length of "attack hold" stage more
1534 accurate. Release stage can now start before attack stage
1535 ends. Cancel release didn't work when sustain was zero. Attack
1536 time now has a minimal value to prevent clicks.
1537 - fixed pitch changes larger than one octave
1538 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1539 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1540 all modes can be altered via standard GM messages, that is CC5 for
1541 altering portamento time, CC65 for enabling / disabling portamento
1542 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1543 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1544 parameter) and crossfade
1545 - added support for the "attenuation controller threshold" gig
1546 parameter
1547 - added smoothing of volume changes caused by control change
1548 messages
1549 - sample loop parameters are now taken from the DimensionRegion
1550 instead of the wave chunk
1551 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1552 not equal to a power of two
1553 - reimplementation of the filter algorithm. The new filter is more
1554 accurate and supports all gig filter types, including bandreject
1555 and lowpass turbo.
1556 - real support for 24 bit samples - samples are not truncated to
1557 16 bits anymore
1558 - support for aftertouch (channel pressure, not polyphonic
1559 aftertouch)
1560 - LFO1 behaviour fixed (dampening from max volume instead of
1561 amplifying from 0)
1563 * LSCP server:
1564 - fixed application exit on broken pipe error (fixes bug #20)
1565 - fixed the notification messages delay due to lack of
1566 network activity (fixes bug #26)
1567 - fixed parser bug which occured on space(s) within device parameters
1570 * audio driver:
1571 - added aRts audio output driver (by no means RT safe)
1573 * MIDI driver:
1574 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1575 messages several times instead of once
1576 - API extension for MIDI drivers which already supply exact time stamps
1577 for events (i.e. for offline rendering based MIDI drivers)
1578 - added checks for bad MIDI data
1580 * linuxsampler application:
1581 - show available sampler engine types on startup
1583 * general changes:
1584 - support for muting sampler channels and solo mode of the same, two new
1585 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1586 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1587 introduced for this, the behavior is the same like on a mixer console
1588 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1589 --enable-process-muted-channels which can be used to enable the
1590 processing of muted channels.
1591 - support for sostenuto pedal
1592 - support for monitoring the total number of active voices
1595 - fixed some memory management errors
1596 - fixed some concurrency problems that could lead to crashes when
1597 LSCP commands were executed
1598 - fixed crash when instrument loading failed previously on the same
1599 sampler channel (fixes bug #36)
1601 Version 0.3.3 (15 July 2005)
1603 * packaging changes:
1604 - fixed compilation with gcc 4.0
1606 * Gigasampler format engine:
1607 - LFO preprocessing was performed even though the respective LFO was
1608 disabled by the instrument patch (minor efficiency fix)
1609 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1610 for volume ramp downs in the same fragment (needed for current voice
1611 stealing implementation) then simply inform the user with a warning
1612 about possible click sounds and reduce the volume ramp down
1613 appropriately instead of cancelling the audio device connection
1615 Version 0.3.2 (24 June 2005)
1617 * packaging changes:
1618 - updated autotools build files to compile on OS X
1619 (conditional compilation of CoreMIDI and MidiShare drivers)
1620 - hand-crafted assembly optimization code can be disabled with
1621 './configure --disable-asm' (definitely not recommended)
1622 - fixed 'make dist' rule to include all necessary files
1623 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1624 (due to 'dist-bzip2' automake option)
1626 * Gigasampler format engine:
1627 - support for the gig parameters for "release velocity response" curves
1628 - fine tuning of the EGADSR envelope
1629 - volume of release triggered samples now depends on note-on velocity,
1630 note length and gig parameter "release trigger decay" instead of
1631 note-off velocity.
1632 - revised voice stealing
1633 (fixes crash and endless loop caused by voice stealing)
1634 - don't reset scale tuning on instrument or audio output device change
1635 - handle key group conflicts right at the beginning of each fragment
1636 instead of when the respective voice is actually launched
1637 (fixes undefined behavior if stolen voices belonged to a key group -
1638 this case was followed by a "killed voice survived" error message)
1639 - fixed minor issue with null/silence samples
1640 (those stole voices even though they don't need a voice at all which
1641 resulted in "voice stealing didn't work out" messages)
1642 - don't reset volume, pan, pitch and MIDI controller values on
1643 instrument or audio output device change
1645 * LSCP server:
1646 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1647 - fixed LSCP event "CHANNEL_INFO" notification
1648 (e.g. did not notify on volume changes or MIDI program change events)
1650 * linuxsampler application:
1651 - added command line parameters --lscp-addr and --lscp-port to override
1652 default IP address and port of LSCP server
1654 Version 0.3.1 (24 May 2005)
1656 * initial release
