* Added support for 'null function RPN/NRPN' (which is RPN/NRPN
  parameter MSB=127 and LSB=127, and which is disabling subsequent
  data entry/increment/decrement CC messages.

* Bumped version (2.1.1.svn35).

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

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

465 - Fixed all change_*() built-in script functions to apply their
466 synthesis parameter changes immediately in case the respective note
467 was triggered at the same time, instead of scheduling the parameter
468 change, especially because it would cause some parameter types's
469 changes either to be ramped (i.e. change_vol()) or other types even
470 to have not effect at all (i.e. change_attack()).
471 - Implemented built-in script function "sh_left()".
472 - Implemented built-in script function "sh_right()".
473 - Implemented built-in script function "min()".
474 - Implemented built-in script function "max()".
475 - NKSP Fix: "init" event handler was not always executed when a script
476 was loaded.
477 - NKSP built-in wait() script function: abort script execution if
478 a negative or zero wait time was passed as argument (since this is
479 a common indication of a bug either of the script or even of the
480 engine, which could lead to RT instability or even worse).
481 - ScriptVM: Implemented automatic suspension of RT safety
482 threatening scripts.

495 - Implemented built-in script function "fade_out()".
496 - Fixed acceptance of wrong data type of parameters passed to built-in
497 script functions "change_vol()", "change_tune()", "change_pan()",
498 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
499 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
500 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
501 - Added built-in script function "get_event_par()" and implemented some
502 of its possible parameter selections.
503 - Added built-in script function "set_event_par()" and implemented some
504 of its possible parameter selections.
505 - Fixed a bunch of scheduler time related bugs.
506 - Fixed polyphonic variables not being reset to zero after usage.
507 - Built-in "ignore_event()" function: argument is now optional, like with
508 built-in function "ignore_controller()".
509 - Implemented built-in script function "change_velo()".
510 - Implemented built-in script function "change_note()".
511 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
512 intuitive behavior if used in combination with "change_vol_time()" or
513 "change_tune_time()" respectively: now tuning/volume changes are only
514 assigned (without delay) immediately to a new note if the respective
515 timing function has not been called before, otherwise the volume/tuning
516 changes are automatically faded (before, only the event's time stamp was
517 relevant).
518 - Implemented built-in script function "array_equal()".
519 - Implemented built-in script function "search()".
520 - Implemented built-in script function "sort()".
521 - NKSP Fix: Never suspend "init" event handlers.

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

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

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

602 - removed empty directories left from the cvs to svn migration
603 - fixed compilation with gcc 4.6.1
604 - another "make dist" fix, for the LV2 plugin
605 - made --enable-pthread-testcancel default on Mac OS X
606 - minor Makefile fix for building lscpparser when build and source
607 directories are separate
608 - Mac OS X: made it possible to specify plugin installation dir to
609 configure
610 - Mac OS X: Makefile fix for the install-strip target
611 - fixed compilation with gcc 4.7
612 - fixed configure script error with old autoconf versions
613 - lsatomic.h: use gcc provided atomic functions if building with
614 gcc 4.7 and C++11
615 - modernized configure script
616 - fixed linkage error when building with
617 LDFLAGS="-Wl,--no-undefined" (#190)
618 - fixed compilation with Clang 3.2
619 - removed usage of deprecated Automake variable INCLUDES

621 - build fix: ChangeFlagRelaxed.h was missing in makefile
622 - build fix: libsndfile compiler flags were missing in some
623 makefiles
624 - fix for building with bison 3.0 (#202)
625 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
626 on the process's main thread
627 - fixed build error on newer MinGW
628 - support building with older jack versions
629 - support building with spaces in vst sdk path
630 - enabled automake 'subdir-objects' option and moved external
631 source references (vst, au, asio) from makefiles to cpp files,
632 in order to get rid of warnings from automake 1.14
634 * general changes:
635 - Refactoring: moved the independent code from
636 the Gigasampler format engine to base classes
637 - command line option '--profile' is currently disabled, since the
638 respective profiling code is currently broken
639 - Introduced support for optional environment variable
640 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
641 where the sampler shall look for instrument editor plugins
642 (patch by Luis Garrido, slightly modified).
643 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
644 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
645 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
646 note (in this implementation of the sampler its simply hard routed to
647 the 1st effect send of the sampler channel, no matter what the actual
648 effect type is)
649 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
650 note (in this implementation of the sampler its simply hard routed to
651 the 2nd effect send of the sampler channel, no matter what the actual
652 effect type is)
653 - implemented support for internal LADSPA effects
654 - raised limit of program change queue from 100 to 512
655 (as suggested by Alex Stone)
656 - implemented sine LFO, pulse LFO and saw LFO
657 - experimental support for per voice equalization
658 - added command line option --exec-after-init
659 - Introduced new C++ API method:
660 EngineChannel::InstrumentFileName(int index)
661 allowing to retrieve the whole list of files used for the loaded
662 instrument on an engine channel (a.k.a. part). Some GigaStudio
663 instruments for example are splitted over several files like
664 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
665 - Added new C++ API method Sampler::GetGlobalMaxVoices().
666 - Added new C++ API method Sampler::GetGlobalMaxStreams().
667 - Added new C++ API method Sampler::SetGlobalMaxVoices().
668 - Added new C++ API method Sampler::SetGlobalMaxStreams().
669 - Various "const" and "restrict" optimizations.
670 - all engines: add pan CC value to instrument pan parameter before
671 applying panning, instead of using two separate pan functions in
672 series (#182)
673 - added a lock guard class for exception safe mutex handling and
674 used it everywhere appropriate
675 - Immediately apply scale tuning changes to active voices.
676 - Exposed scale tuning to C++ API (along to the already existing standard
677 SysEx way).
678 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
679 and broken for ppc64. (Seq_cst loads and stores are actually not
680 used in LS, so the bug wasn't noticable.)
681 - lsatomic.h: added ARMv7 support
682 - Added support for multiple MIDI input ports per sampler channel (and
683 added various new C++ methods for this new feature / design change, old
684 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
685 as deprecated but are still there and should provide full behavior
686 backward compatibility).
687 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
688 unsafe and caused compilation error with clang 2.x).
689 - Bugfix: only process the latest MIDI program change event.
690 - Introducing the LSCP shell, which provides convenient control of the
691 sampler from the command line by providing LSCP aware features.
692 - VirtualMidiDevice: Added support for program change.
693 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
694 - VirtualMidiDevice: Added support for pitch bend.
695 - Aftertouch: extended API to explicitly handle channel pressure and
696 polyphonic key pressure events (so far polyphonic pressure was not
697 supported at all, and channel pressure was rerouted as CC128 but not
698 used so far).
699 - Added initial support for real-time instrument scripts. The script VM
700 code is shared by all sampler engine implemementations, however only the
701 gig file format currently provides support for storing instrument scripts
702 (as LinuxSampler extension to the original GigaStudio 4 format).
704 * Gigasampler format engine:
705 - implemented the "round robin keyboard" dimension
706 - fixed round robin and random dimensions for cases when number of
707 dimension zones is not a power of two
708 - made round robin use a counter for each region instead of each
709 key
710 - bugfix: pitch LFO controller "internal+aftertouch" was broken
711 - bugfix: filter keyboard tracking was broken
712 - filter performance fix (an unnecessary copy was made of the
713 filter parameters in each sub fragment)
714 - handle special case when pan parameter in gig file has max or
715 min value
716 - Exclusive Groups: don't ever stop voices of the same note,
717 doesn't sound naturally with a drumkit
718 - fixed EG1 modulation when attack or release is zero
719 - Fixed support for 'aftertouch' attenuation controller.
720 - Fixed crash that happened with velocity split sounds under certain
721 conditions (see also previous commit on libgig).
722 - fixed behaviour of filter LFO
724 * SFZ format engine:
725 - Initial implementation (not usable yet)
726 - added support for v2 multiple stage envelope generators
727 - added a fine-tuned v1 envelope generator instead of using the
728 one from the gig engine
729 - fixed memory leak and memory handling errors
730 - added support for trigger=first, trigger=legato and sw_previous
731 - allow non-numerical key values ("C#4" for example)

733 - fixed error when unloading instrument with same sample used by
734 multiple regions
735 - added some opcode aliases, like loopmode for loop_mode, to be
736 more compatible
737 - added support for trigger=release and rt_decay
738 - added support for off_mode=normal
739 - added support for random, seq_position, seq_length and volume

746 - added more v1 aliases to parser
747 - reduced memory usage for sfz data
748 - RT-safeness: avoid malloc in audio thread
749 - fixed a bug that could cause voice stealing to fail
750 - optimized sample lookup
751 - improved support for exclusive groups (group, off_by and
752 off_mode)
753 - added support for controller triggered regions (on_locc/on_hicc)
754 - added support for loop_mode=one_shot
755 - fixed playback of 16 bit wav files on big endian CPUs
756 - added support for Ogg Vorbis sample files
757 - use loop markers from sample file if loop_start and loop_end are
758 not set in sfz file
759 - implemeted filters. Filter types: lowpass, bandpass, bandreject
760 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
761 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
762 cutoff_cc, cutoff_chanaft.
763 - bugfix: zero ampeg_sustain didn't work
764 - added support for velocity effect on amplifier envelope time
765 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
766 ampeg_vel2release)
767 - added support for EG hold (ampeg_hold)

899 - AU bugfix: failed to destroy its audio/MIDI devices
900 - Listen to all interfaces on Mac OS X (INADDR_ANY)
901 - VST bugfix: If the host called resume() before and after
902 changing sample rate or block size, the number of channels was
903 incorrectly set to two. This caused silence in Cubase 5.
904 - save engine type (gig, sfz or sf2) in plugin state

952 the driver will automatically connect to other CoreMIDI clients' ports
953 (e.g. external MIDI devices being attached to the Mac)
954 - added support for MIDI note on velocity filter
955 - CoreMIDI: fixed memory deallocation error
956 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
957 virtual keyboards in frontends / instrument editors being stuck.
958 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
959 - Implemented missing handling of MIDI "running status".
960 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
961 - MME bugfix: driver wasn't closed properly

1016 (suggesting expected next non-terminal symbols)
1017 - Fixed client connection not being closed after network errors.
1019 * LSCP shell:
1020 - Added support for auto correction of obvious and trivial syntax mistakes.
1021 - Added support for auto completion by tab key.
1022 - Show currently available auto completion while typing.
1023 - Added support for browsing command history with up / down keys.
1024 - Show all possible next symbols immediately right to the current command

1026 be the case in other shells).
1027 - Added support for moving cursor left/right with arrow keys.
1028 - Added support for built-in LSCP reference documentation, which will
1029 automatically show the relevant LSCP reference section on screen as soon

1077 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1078 (i.e. return value of new script function "by_marks()").
1079 - Pass/preserve polyphonic variable data from respective "note" event
1080 handler to "release" event handler.

1087 channel to a different engine type
1088 - fixed crash when deleting a sampler channel or changing engine
1089 type while an instrument load was in progress
1090 - bugfix: playing a note while changing the instrument could cause
1091 a crash, or give "Handing back unknown region" error messages
1092 - bugfix: calling SET VOICES (which Fantasia does on start and
1093 refresh) could cause instruments to be unloaded
1094 - Mac OS X: fixed name collision of enum in EffectControl and
1095 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1096 - Mac OS X: fixed hanging threads
1097 - Windows: disabled the previous thread fix on non-Mac systems, as
1098 it caused hanging threads on Windows
1099 - Fixed possible crashes due to corrupted MIDI/audio device list
1100 after MIDI/audio device creation failure
1101 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1102 instruments were uselessly precached with zero samples, however it still
1103 took the full preloading time and on 1st program change the respective
1104 instrument was completely reloaded again.
1105 - fixed handling of rapid bank select and program change messages
1106 sent to the same sampler channel (patch from the Open Octave
1107 project, slightly adjusted)

1122 playing a note in a key group
1123 - fixed erroneous error message piping in VoiceBase.h
1124 (labelled "Disk stream not available in time")
1125 - Update effects on sample rate & period size changes (to avoid
1126 crashes and noise on such transitions).
1127 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1128 (fixes #208)
1129 - Fixed bug in LSCP grammar definition which caused a statement like
1130 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1131 practically irrelevant, however it caused problems with the new LSCP
1132 shell's auto completion feature).
1133 - Fixed MIDI program change messages being ignored if quickly executed
1134 after each other (fixes #231).
1136 Version 1.0.0 (31 July 2009)
1138 * packaging changes:
1139 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1140 causing e.g. the libgig test to fail when
1141 "./configure --disable-jack-driver" was used
1142 (patch by Alexis Ballier)
1143 - fixed compilation with gcc 4.3
1144 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1149 - minor fix in configure for mmsystem.h detection on MinGW
1150 - Windows: look for editor plugins and Fantasia using base
1151 directory of liblinuxsampler dll (look in the same directory and one
1152 directory above)
1153 - configure script fix: removed unconditional use of SSE
1154 - fixed building with sqlite installed in a non-standard directory
1155 - when cross-compiling, don't try to create instruments.db
1156 - fix for new mingw-w64 version, which has usleep
1158 * general changes:
1159 - bugfix: on some POSIX systems instrument editor plugins refused to
1160 load as we used a non-portable Linux specific struct field
1161 (fixes bug #70, patch by Ronald Baljeu)
1162 - fixed endless loop which occured when loading an instrument editor
1163 plugin DLL on Windows systems failed
1164 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1165 - optimized the SynchronizedConfig class so it doesn't wait
1166 unnecessarily long after an update
1167 - added support for notifying instrument editors on note-on / note-off
1168 events (e.g. to highlight the pressed keys on the virtual keyboard
1169 of gigedit)
1170 - added support for triggering notes by instrument editors (see above)
1171 - be verbose on DLL load errors (on Linux)
1172 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1173 is only used by very few systems, most pick the int math
1174 implementation, which is usually faster)
1175 - fixes for audio drivers with varying buffer sizes
1176 - experimental support for running LinuxSampler as a DSSI, LV2 and
1177 VST plugin
1178 - notification events for stream/voice count statistics are now sent
1179 only when there are actual changes
1180 - added memory ordering constraints to improve stability on
1181 multi-core and multi-cpu systems
1182 - maximum voices and disk streams can now be altered at runtime
1183 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1184 - automatic stacktrace mechanism is now turned off by default and can
1185 be switched on by command line option "--stacktrace" (the automatic
1186 stacktrace mechanism seems to be broken on most systems at the moment)
1187 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1188 a pointer to the launched InstrumentEditor object
1189 - added optional 3rd party user data parameter for following
1190 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1191 InstrumentEditor::Launch(),
1192 InstrumentManager::LaunchInstrumentEditor()
1193 - theoretical fix: made SynchronizedConfig follow C++0x memory
1194 model more strictly
1195 - fixes for using large audio device buffers
1196 - Windows: add the installation directory to the DLL search path
1197 when loading an editor plugin (solves problems with VST and
1198 gigedit on systems with other GTK versions installed)
1199 - updated linuxsampler man page
1201 * audio driver:
1202 - removed the nonsense audio channel constraint (which was hard coded to
1203 max. 100 audio channels) for most audio drivers
1204 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1205 opposed to the LSCP specs
1206 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1207 reflected the wrong value
1208 - fixed a memory management bug in ASIO driver
1209 - Makefile fix: JACK_CFLAGS wasn't used
1210 - JACK: use jack_client_open instead of the deprecated
1211 jack_client_new
1212 - added (experimental) CoreAudio driver
1213 - applied old fixes to the ASIO driver that were included in the
1214 previous binary release but accidentally never committed to CVS
1215 (fixes #117)
1216 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1217 win64)
1218 - VST: added support for sample rate and buffer size changes
1219 - VST: close editor (Fantasia) when the VST is removed
1220 - VST: avoid opening Fantasia more than once for each VST instance
1221 - VST: export main function as "main" on Linux too (fix for
1222 energyXT)
1223 - VST: changed number of output channels from one stereo to 16
1224 stereo
1225 - added channel routing, fxsends and midi maps to the settings
1226 stored in the plugin state
1227 - performance optimization of AudioChannel::MixTo() and
1228 AudioChannel::CopyTo() methods using GCC vector exensions
1229 (if available)
1230 - ASIO fixes: avoid initializing the device twice, avoid throwing
1231 exception when getting parameters from a disconnected device
1233 * MIDI driver:
1234 - added JACK MIDI driver
1235 - dispatch bank select as ordinary CC as well, the user might seriously
1236 want to (mis)use it for some purpose ("fixed" in all current MIDI
1237 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1238 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1239 CoreMidi or AU
1240 - fixed mingw-w64 compilation error in MME driver
1241 - made program change handling in MIDI thread real-time safe by
1242 moving the logic to a non-RT thread
1243 - fixed minor memory leak in ALSA driver
1245 * instruments database:
1246 - avoid time consuming samples scanning when adding instruments
1247 to the instruments database
1248 - added support for handling lost files in the instruments database
1249 - Implemented option for adding instruments in separate directories
1250 in the instruments database
1251 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1252 - work-around for missing fnmatch function on Windows to make
1253 instrument database compilable
1254 - added instrument database support on Windows
1255 works with both standalone mode and VST plugin.
1256 the instruments DB file is located in
1257 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1258 databases for each windows user
1259 if no DB is present it automatically creates the .linuxsampler subdir
1260 and then creates an empty DB
1261 - fixed recursive import, which was broken on Windows
1263 * Gigasampler format engine:
1264 - fixed a memory leak that could happen when a channel was deleted
1265 while notes were playing
1266 - made it possible to load an instrument even if the audio thread
1267 isn't running
1268 - added partial support for the "Controller Triggered" MIDI rule,
1269 enough for piano gigs with pedal noise samples
1270 - minor fix: only mark FX sends as being modified if really the
1271 respective FX send MIDI controller was used
1272 - added support for GM global device volume SysEx message
1273 (can be selected at compile time to either apply globally to the
1274 whole sampler [default] or only to the sampler channels that are
1275 connected to the respective MIDI input port the SysEx message arrived
1276 on)
1277 - bugfix: notes triggered at position 0 in the audio buffer were
1278 sometimes wrongly killed in the same buffer, causing no sound to
1279 be played
1280 - added support for chromatic / drumkit mode Roland GS Sysex message
1281 which is usally used to switch a part between chromatic sounds and
1282 drumkit sounds (as opposed to their common default setting of MIDI
1283 part 10 being a drumkit part and all other ones chromatic parts), in
1284 LS however one can switch between the first 16 MIDI instrument maps
1285 defined for the sampler
1286 - made it possible to create multiple sample channels even if the
1287 audio thread isn't running
1288 - fixed crash when removing channel with active voices (#116)
1289 - bugfix: on sample reference changes (instrument editor), only
1290 un-cache the respective sample if it's really not used by any
1291 sampler engine anymore
1292 - re-cache samples in case they were changed by an instrument editor,
1293 e.g. when a sample was added while playing (#82)
1294 - fixed hanging notes which occured when note-off event had the exact
1295 same time stamp as the voice's note-on event and occured both in the
1296 same audio fragment cycle (fixes bug #112)
1297 - added support for the "fine tune" and "pitch bend range"
1298 instrument-level gig parameters
1299 - fixed minor artifacts in pitch bend handling
1300 - added support for GS Reset SysEx message
1301 - allow gig files to use unlimited downward pitch shifting
1302 - added a limit check for upward pitch shifting
1303 - bugfix: sometimes, when playing a note twice fast, the second
1304 note was silent
1305 - fixed crash happening when a pitch bend event arrived at the
1306 same time a new instrument was loading
1308 * LSCP server:
1309 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1310 react on MIDI data arriving on certain sampler channels (so far only
1311 Note-On and Note-Off events are sent via this LSCP event)
1312 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1313 react on MIDI data arriving on certain MIDI input devices (so far only
1314 Note-On and Note-Off events are sent via this LSCP event)
1315 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1317 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1318 frontends to send MIDI messages to specific sampler channel
1319 - added two additional fields to GET FILE INSTRUMENT INFO command -
1321 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1322 was incorrect
1323 - Optimized the retrieval of the MIDI instrument mappings
1324 - added new LSCP command "SET VOICES" to globally alter the maximum
1325 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1326 be triggered respectively
1327 - added new LSCP command "SET STREAMS" to globally alter the maximum
1328 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1329 which will be triggered respectively
1330 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1331 a gigedit file dialog is opened)
1332 - close all connections when LSCPServer is deleted
1333 - hard close of all sockets on exit
1334 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1335 driver
1337 * Bug fixes:
1338 - fixed a crash which occurs when removing a sampler channel waiting
1339 to start instrument loading after another channel
1340 - fixed a crash which occurs when removing a sampler channel with
1341 instrument loading in progress (bug #113)
1342 - fixed termination caused by uncaught exception when adding MIDI
1343 instrument with PERSISTENT load mode
1344 - fixed possible iterator invalidations when resetting the sampler
1345 - fixed memory leaks when issuing the following LSCP commands:
1350 - fixed possible compilation error when sqlite is not present
1351 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1352 - fixed crash when changing the audio output device of a sampler
1353 channel with loaded instrument and start playing notes
1354 - fixed endless loop in Engine::SuspendAll() (bug #120)
1355 - fixed a low-level atomic load function that was broken on 64-bit
1356 PowerPC, which probably could cause crashes on that platform
1357 - fixed a memory management error which could cause a crash when a
1358 plugin was unloaded
1359 - bugfix: two private structs had the same name, which could cause
1360 problems if the linker chose the wrong constructor
1361 - fixed low-level ConditionServer usage bug that caused lockups on
1362 Windows
1365 Version 0.5.1 (6 December 2007)
1367 * packaging changes:
1368 - added autoconf checks for pthread library
1369 - added autoconf check for pthread bug found on certain NPTL-enabled
1370 glibc versions (see Gentoo bug report #194076)
1371 - added autoconf checks for MS Windows
1373 * general changes:
1374 - bugfix: the thread used by an editor plugin didn't die when the
1375 editor closed
1376 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1377 out all the space. operator--() did not apply size_mask after
1378 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1379 order to avoid problems with the _NonVolatileReader functions.
1380 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1381 GetWriteSpace(). Since this function is currently only used in
1382 the stream's qsort() compare function, it didn't trigger any
1383 bugs.
1384 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1385 24bit mode too. Faster method to read 24bit words on little
1386 endian machines (x86): replaced 3 byte reads + shifts with a 1
1387 unaligned 32bit read and shift
1388 - experimental support for MS Windows (MIDI input via MME, AUDIO
1389 output via ASIO)
1390 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1391 - support for monitoring the total number of active disk streams
1392 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1395 * AUDIO driver:
1396 - added Windows ASIO low latency audio driver
1398 * MIDI driver:
1399 - added MME Windows MIDI driver
1401 * LSCP server:
1402 - added support for Windows style path / filenames, however with
1403 forward slash path separators instead of backslash
1404 (i.e. "C:/foo/bar.gig")
1405 - allow naughty liblscp to send non-string device parameters within
1406 apostrophes as well
1407 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1408 "LIST FILE INSTRUMENTS <file>" and
1409 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1410 about an arbitrary instrument file on the system where the sampler is
1411 running on
1413 Version 0.5.0 (15 October 2007)
1415 * packaging changes:
1416 - config.h is not going to be installed along with liblinuxsampler's
1417 API header files anymore
1418 - only the API relevant header (and source) files will be exported to
1419 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1420 - added completely new XCode project files for Mac OSX which is now
1421 capable to execute our autoconf environment, thus no need anymore
1422 to maintain the compile time configuration file (osx/version.h) for
1423 OSX manually (patch by Toshi Nagata)
1424 - fixed buggy boolean --enable-foo / --disable-foo configure script
1425 parameters
1426 - global.h now only covers global definitions that are needed for the
1427 C++ API header files, all implementation internal global definitions
1428 are now in global_private.h
1429 - atomic.h is not exposed to the C++ API anymore
1430 - no need to include config.h anymore for using LS's API header files
1431 - fixed warnings in API doc generation
1433 * general changes:
1434 - replaced the old, confusing MIDI program change mechanism by a
1435 flexible MIDI instrument mapper which allows to map arbitrary
1436 (MIDI bank, MIDI program) pairs with arbitrary
1437 (engine type, instrument file, file index) triplets which will be
1438 loaded on the respective channel when such MIDI program change
1439 messages arrive, beside that, each entry allows to define a life-time
1440 strategy for the instrument, so the user can define whether the
1441 instrument should i.e. be permanently loaded (to be able to switch
1442 quickly among sounds) or i.e. loaded just on demand when the
1443 respective program change arrives (to safe RAM space), as well as a
1444 global volume factor for each entry, so the user can adjust the volume
1445 dynamic of his mapped instrument collection without having to modify
1446 the instrument files, also one can manage arbitrary amount of such
1447 MIDI instrument maps and assign each sampler channel individually
1448 a certain map, so that i.e. separation of normal instruments and
1449 drumkits is possible
1450 - new notification events for tracking changes to audio/MIDI devices,
1451 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1452 - sampler was limited to load max. 200 instruments in the background
1453 due to a constant size RingBuffer FIFO which is now replaced by a
1454 dynamic (unlimited) size std::list FIFO
1455 - added FX sends, these allow to route audio signals to arbitrary audio
1456 output channels for being processed by external effect processors
1457 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1458 controllers
1459 - global (sampler wide) volume can now be controlled at runtime
1460 - Implemented new, improved notification system
1461 - fixed compilation errors regarding OSX
1462 (patch by Toshi Nagata)
1463 - implemented instruments database
1464 - added support for escape sequences to the instruments database
1465 - added highly experimental support for on-the-fly instrument editing
1466 within the sampler's process (by using instrument editor plugins),
1467 you'll notice the new "Registered instrument editors:" message on
1468 startup, added a new LSCP command:
1469 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1470 to spawn a matching instrument editor for the instrument on the
1471 given sampler channel, the plugin path can be overridden at compile
1472 time with ./configure --enable-plugin-dir=/some/dir
1473 - added experimental code for synchronizing instrument editors hosted
1474 in the sampler's process to safely edit instruments while playing
1475 without a crash (hopefully) by either suspending single regions
1476 wherever possible or if unavoidable whole engine(s)
1477 - fixed several issues in fundamental "Thread" class: set scheduling
1478 policy and priority on thread level, set a minimum stack size for
1479 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1480 threads simply inherited properties of starting thread instead of
1481 setting their own policy and priority
1482 - minor fix in our automatic stack trace mechanism on crashes, the
1483 main process did not wait for the stack trace process to finish
1484 its output
1485 - fixed some minor memory leaks
1486 - reenabled assembly features support, at the moment only for
1487 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1488 - minor assembly fix in x86 features detection (don't use the PIC
1489 register, to avoid relocations in the text segment at runtime)
1490 - POSIX callback functions of Thread.h are hidden
1492 * MIDI driver:
1493 - dispatch bank select (MSB and LSB) messages
1495 * audio driver:
1496 - the ALSA audio output driver parameters now reflect the correct
1497 parameter value ranges for the respective selected sound card
1498 (patch by Till Wimmer, a bit fixed and extended)
1500 * Gigasampler format engine:
1501 - if a filter is used and EG2 finishes before EG1, let the voice
1502 die when EG2 has finished (this fixes a problem with clicks and
1503 voice starvation for some gigs)
1504 - playback is no longer disabled during instrument loading
1505 - all notes playing on a channel that changes its instrument keep
1506 playing with the old instrument until they get a note off
1507 command
1508 - EG fix: a release value of zero could cause noises or crash
1509 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1510 - EG fine tuning: when attack is zero the EG starts at a level
1511 above max sustain level, which means that there is a decay phase
1512 even if sustain is 100%
1513 - more EG fixes: the level could sometimes go below zero and cause
1514 noises or crashes
1515 - minor fix of EGDecay (patch by Toshi Nagata)
1516 - fixed compiler error when --enable-override-filter-type was
1517 supplied to the configure script (fixes #46)
1518 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1519 instead of a fix value
1520 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1521 127 (solo mode) only kill voices if the respective mode really
1522 changed
1524 * LSCP server:
1525 - fixed compile time error for old Bison versions
1526 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1527 - parser now supports extended ASCII character set
1528 (up to ASCII code 255, i.e. includes now umlauts and accents)
1529 - filename arguments in LSCP commands now allow to use escape
1530 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1531 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1532 code value like \xf2) (fixes bug #24)
1533 - the following LSCP commands now also support escape sequences for at
1534 least one of their text-based parameters (i.e. name, description):
1541 - returns verbose syntax errors (line and column where syntax error
1542 occured, the unexpected character and the actually expected, possible
1543 character(s), the latter only if less than 5 possibilities)
1544 - made sure that LSCP syntax is not affected by gigedit locale
1545 settings
1546 - bugfix regarding strings parameter lists: all comma separated lists
1547 of strings were treated as being one string containing commas
1548 (fixes #57)
1550 * Bug fixes:
1551 - fixed crash occurring on certain LSCP scripts (Bug 39)
1552 - another thread safety fix for lscp "load engine" and "set
1553 channel audio output device"
1554 - fixed a crash which occurs when reassigning the same engine
1555 on a sampler channel with connected MIDI device
1556 - fixed a crash which occurs when changing the number of ports of a MIDI
1557 device connected to a sampler channel to number less then or equal
1558 to the index of the port to which the sampler channel is connected.
1559 - The previous bindings were not been disconnected when altering
1560 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1561 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1562 - The active stream/voice count statistic was incorrect.
1563 - notification events were not been sent for some sampler
1564 channel changes
1565 - added default min and max values to restrict the number of allowed
1566 audio output channels and MIDI input ports
1567 - the connection to the PCM interface is now closed when destroying
1568 an audio output device
1569 - files with slash in their path or filename could not be loaded
1571 * test cases:
1572 - updated and fixed (haven't been touched in a while)
1574 Version 0.4.0 (24 November 2006)
1576 * packaging changes:
1577 - changed deprecated copyright attribute to license; added ldconfig
1578 to post-(un)install steps; added devel package for liblinuxsampler;
1579 to linuxsampler.spec (RPM)
1580 - install necessary development header files for allowing 3rd party
1581 applications to link against liblinuxsampler
1582 - liblinuxsampler's API documentation can be generated with 'make docs'
1583 (Doxygen required)
1584 - added benchmark to automatically detect the best triangle LFO
1585 implementation (currently either an integer math solution or a
1586 di-harmonic approximation), automatic detection can be overriden
1587 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1588 configure script argument though (mandatory for cross-compilation)
1589 - do not automatically pick optimized gcc flags if the user already
1590 provided some on his own (as CXXFLAGS)
1591 - added compile time option to disable processing of All-Notes-Off MIDI
1592 messages
1593 - added compile time options to allow disabling the various audio and
1594 MIDI drivers
1595 - fixed automatic GCC CPU switch detection on PPC
1596 (patch by Ebrahim Mayat)
1598 * Gigasampler format engine:
1599 - extensive synthesis optimization
1600 (reimplementation of EGs and LFO(s), removed synthesis parameter
1601 prerendering and the synthesis parameter matrix in general, splitting
1602 each audio fragment into subfragments now where each subfragment uses
1603 constant pitch and filter coefficients. The volume coefficient is
1604 linearly interpolated inside a subfragment, unless
1605 --disable-interpolate-volume is set.)
1606 - fine tuning of the EG modulation parameters
1607 - improved filter cutoff calculation by adding support for the
1608 following gig parameters: Cutoff freq (used when no cutoff
1609 controller is defined), Control invert, Minimum cutoff, Velocity
1610 curve and Velocity range. The keyboard tracking now scales
1611 cutoff frequency instead of resonance.
1612 - added support for gig parameter Resonance.
1613 - fixed bug in sysex handling (patch by Juan Linietsky)
1614 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1615 which can be overridden with --enable-global-attenuation
1616 - EG fixes: made the length of "attack hold" stage more
1617 accurate. Release stage can now start before attack stage
1618 ends. Cancel release didn't work when sustain was zero. Attack
1619 time now has a minimal value to prevent clicks.
1620 - fixed pitch changes larger than one octave
1621 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1622 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1623 all modes can be altered via standard GM messages, that is CC5 for
1624 altering portamento time, CC65 for enabling / disabling portamento
1625 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1626 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1627 parameter) and crossfade
1628 - added support for the "attenuation controller threshold" gig
1629 parameter
1630 - added smoothing of volume changes caused by control change
1631 messages
1632 - sample loop parameters are now taken from the DimensionRegion
1633 instead of the wave chunk
1634 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1635 not equal to a power of two
1636 - reimplementation of the filter algorithm. The new filter is more
1637 accurate and supports all gig filter types, including bandreject
1638 and lowpass turbo.
1639 - real support for 24 bit samples - samples are not truncated to
1640 16 bits anymore
1641 - support for aftertouch (channel pressure, not polyphonic
1642 aftertouch)
1643 - LFO1 behaviour fixed (dampening from max volume instead of
1644 amplifying from 0)
1646 * LSCP server:
1647 - fixed application exit on broken pipe error (fixes bug #20)
1648 - fixed the notification messages delay due to lack of
1649 network activity (fixes bug #26)
1650 - fixed parser bug which occured on space(s) within device parameters
1653 * audio driver:
1654 - added aRts audio output driver (by no means RT safe)
1656 * MIDI driver:
1657 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1658 messages several times instead of once
1659 - API extension for MIDI drivers which already supply exact time stamps
1660 for events (i.e. for offline rendering based MIDI drivers)
1661 - added checks for bad MIDI data
1663 * linuxsampler application:
1664 - show available sampler engine types on startup
1666 * general changes:
1667 - support for muting sampler channels and solo mode of the same, two new
1668 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1669 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1670 introduced for this, the behavior is the same like on a mixer console
1671 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1672 --enable-process-muted-channels which can be used to enable the
1673 processing of muted channels.
1674 - support for sostenuto pedal
1675 - support for monitoring the total number of active voices
1678 - fixed some memory management errors
1679 - fixed some concurrency problems that could lead to crashes when
1680 LSCP commands were executed
1681 - fixed crash when instrument loading failed previously on the same
1682 sampler channel (fixes bug #36)
1684 Version 0.3.3 (15 July 2005)
1686 * packaging changes:
1687 - fixed compilation with gcc 4.0
1689 * Gigasampler format engine:
1690 - LFO preprocessing was performed even though the respective LFO was
1691 disabled by the instrument patch (minor efficiency fix)
1692 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1693 for volume ramp downs in the same fragment (needed for current voice
1694 stealing implementation) then simply inform the user with a warning
1695 about possible click sounds and reduce the volume ramp down
1696 appropriately instead of cancelling the audio device connection
1698 Version 0.3.2 (24 June 2005)
1700 * packaging changes:
1701 - updated autotools build files to compile on OS X
1702 (conditional compilation of CoreMIDI and MidiShare drivers)
1703 - hand-crafted assembly optimization code can be disabled with
1704 './configure --disable-asm' (definitely not recommended)
1705 - fixed 'make dist' rule to include all necessary files
1706 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1707 (due to 'dist-bzip2' automake option)
1709 * Gigasampler format engine:
1710 - support for the gig parameters for "release velocity response" curves
1711 - fine tuning of the EGADSR envelope
1712 - volume of release triggered samples now depends on note-on velocity,
1713 note length and gig parameter "release trigger decay" instead of
1714 note-off velocity.
1715 - revised voice stealing
1716 (fixes crash and endless loop caused by voice stealing)
1717 - don't reset scale tuning on instrument or audio output device change
1718 - handle key group conflicts right at the beginning of each fragment
1719 instead of when the respective voice is actually launched
1720 (fixes undefined behavior if stolen voices belonged to a key group -
1721 this case was followed by a "killed voice survived" error message)
1722 - fixed minor issue with null/silence samples
1723 (those stole voices even though they don't need a voice at all which
1724 resulted in "voice stealing didn't work out" messages)
1725 - don't reset volume, pan, pitch and MIDI controller values on
1726 instrument or audio output device change
1728 * LSCP server:
1729 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1730 - fixed LSCP event "CHANNEL_INFO" notification
1731 (e.g. did not notify on volume changes or MIDI program change events)
1733 * linuxsampler application:
1734 - added command line parameters --lscp-addr and --lscp-port to override
1735 default IP address and port of LSCP server
1737 Version 0.3.1 (24 May 2005)
1739 * initial release
