Added support for MIDI CC #38 (data entry LSB):

* Combine data entry MSB and data entry LSB events' values to one 14-bit
  value, which allows higher resolution (N)RPN value handling.

* Handle now hard coded RPN events in separate method

* Handle now hard coded NRPN events in separate method

* Bumped version (2.1.1.svn29).

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

444 - Fixed all change_*() built-in script functions to apply their
445 synthesis parameter changes immediately in case the respective note
446 was triggered at the same time, instead of scheduling the parameter
447 change, especially because it would cause some parameter types's
448 changes either to be ramped (i.e. change_vol()) or other types even
449 to have not effect at all (i.e. change_attack()).
450 - Implemented built-in script function "sh_left()".
451 - Implemented built-in script function "sh_right()".
452 - Implemented built-in script function "min()".
453 - Implemented built-in script function "max()".
454 - NKSP Fix: "init" event handler was not always executed when a script
455 was loaded.
456 - NKSP built-in wait() script function: abort script execution if
457 a negative or zero wait time was passed as argument (since this is
458 a common indication of a bug either of the script or even of the
459 engine, which could lead to RT instability or even worse).
460 - ScriptVM: Implemented automatic suspension of RT safety
461 threatening scripts.

474 - Implemented built-in script function "fade_out()".
475 - Fixed acceptance of wrong data type of parameters passed to built-in
476 script functions "change_vol()", "change_tune()", "change_pan()",
477 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
478 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
479 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
480 - Added built-in script function "get_event_par()" and implemented some
481 of its possible parameter selections.
482 - Added built-in script function "set_event_par()" and implemented some
483 of its possible parameter selections.
484 - Fixed a bunch of scheduler time related bugs.
485 - Fixed polyphonic variables not being reset to zero after usage.
486 - Built-in "ignore_event()" function: argument is now optional, like with
487 built-in function "ignore_controller()".
488 - Implemented built-in script function "change_velo()".
489 - Implemented built-in script function "change_note()".
490 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
491 intuitive behavior if used in combination with "change_vol_time()" or
492 "change_tune_time()" respectively: now tuning/volume changes are only
493 assigned (without delay) immediately to a new note if the respective
494 timing function has not been called before, otherwise the volume/tuning
495 changes are automatically faded (before, only the event's time stamp was
496 relevant).
497 - Implemented built-in script function "array_equal()".
498 - Implemented built-in script function "search()".
499 - Implemented built-in script function "sort()".
500 - NKSP Fix: Never suspend "init" event handlers.
501 - Implemented built-in script function "same_region()" (currently only
502 available for gig format engine).
503 - Added built-in script constant "$NKSP_LINEAR".
504 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
505 - Implemented built-in script function "change_vol_curve()".
506 - Implemented built-in script function "change_tune_curve()".
507 - built-in "play_note()" function now supports a sample playback start
508 offset with argument 3, where special value -1 means to use the regular
509 sample offset as defined by the instrument file.
510 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
511 - Built-in variable $EVENT_NOTE is now a read-only variable.
512 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
513 - built-in "play_note()" function now accepts -2 for its fourth argument
514 (note duration) which means the life time of the note shall be sticked
515 to the requested note number of argument 1.
516 - Fix: built-in "play_note()" function now returns 0 as result value if
517 -1 was passed for its fourth argument (note duration) and the respective
518 parent note is already gone.
519 - Implemented built-in script function "change_play_pos()".
520 - NKSP language: Added support for user declared const array variables.
521 - NKSP language: Raise parser warning if array variable is accessed with
522 an index that exceeds the array's size.
523 - NKSP language fix: Unknown characters were not handled correctly.
524 - NKSP language: Added support for "synchronized .. end synchronized"
525 code blocks.
526 - Implemented built-in script function "abort()" which allows to abort
527 another script handler by passing its callback ID.
528 - Fixed potential memory access bug and potential undefined behavior of
529 "init" event handlers.
530 - Print a time stamp along to each call of built-in function "message()".
531 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
532 to retrieve all code blocks filtered out by the preprocessor.

540 - Added built-in constant $CALLBACK_STATUS_RUNNING.
541 - Removed max. value limitation of built-in functions "change_attack()",
542 "change_decay()" and "change_release()" to i.e. allow passing 2000000
543 for doubling the respective time.
544 - NKSP script editor syntax highlighting API: Fixed app termination due
545 to a lexer start condition stack underrun.
546 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
547 USE_CODE_IF_NOT() preprocessor statements.
548 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
549 can be set to disable all subsequent built-in "message()" function calls
550 on preprocessor level.
551 - Implemented built-in script function "change_sustain()".
552 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

568 is now optional, if it is missing, then a default location is used.
569 - Added support for scanning SFZ (.sfz) files.
570 - Added support for scanning Sound Font (.sf2) files.
571 - Fixed undefined DB transaction behavior.

583 - another "make dist" fix, for the LV2 plugin
584 - made --enable-pthread-testcancel default on Mac OS X
585 - minor Makefile fix for building lscpparser when build and source
586 directories are separate
587 - Mac OS X: made it possible to specify plugin installation dir to
588 configure
589 - Mac OS X: Makefile fix for the install-strip target
590 - fixed compilation with gcc 4.7
591 - fixed configure script error with old autoconf versions
592 - lsatomic.h: use gcc provided atomic functions if building with
593 gcc 4.7 and C++11
594 - modernized configure script
595 - fixed linkage error when building with
596 LDFLAGS="-Wl,--no-undefined" (#190)
597 - fixed compilation with Clang 3.2
598 - removed usage of deprecated Automake variable INCLUDES

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

712 - fixed error when unloading instrument with same sample used by
713 multiple regions
714 - added some opcode aliases, like loopmode for loop_mode, to be
715 more compatible
716 - added support for trigger=release and rt_decay
717 - added support for off_mode=normal
718 - added support for random, seq_position, seq_length and volume

725 - added more v1 aliases to parser
726 - reduced memory usage for sfz data
727 - RT-safeness: avoid malloc in audio thread
728 - fixed a bug that could cause voice stealing to fail
729 - optimized sample lookup
730 - improved support for exclusive groups (group, off_by and
731 off_mode)
732 - added support for controller triggered regions (on_locc/on_hicc)
733 - added support for loop_mode=one_shot
734 - fixed playback of 16 bit wav files on big endian CPUs
735 - added support for Ogg Vorbis sample files
736 - use loop markers from sample file if loop_start and loop_end are
737 not set in sfz file
738 - implemeted filters. Filter types: lowpass, bandpass, bandreject
739 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
740 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
741 cutoff_cc, cutoff_chanaft.
742 - bugfix: zero ampeg_sustain didn't work
743 - added support for velocity effect on amplifier envelope time
744 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
745 ampeg_vel2release)
746 - added support for EG hold (ampeg_hold)

932 (e.g. external MIDI devices being attached to the Mac)
933 - added support for MIDI note on velocity filter
934 - CoreMIDI: fixed memory deallocation error
935 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
936 virtual keyboards in frontends / instrument editors being stuck.

1058 - Pass/preserve polyphonic variable data from respective "note" event
1059 handler to "release" event handler.

1066 channel to a different engine type
1067 - fixed crash when deleting a sampler channel or changing engine

1069 - bugfix: playing a note while changing the instrument could cause
1070 a crash, or give "Handing back unknown region" error messages
1071 - bugfix: calling SET VOICES (which Fantasia does on start and
1072 refresh) could cause instruments to be unloaded
1073 - Mac OS X: fixed name collision of enum in EffectControl and
1074 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1075 - Mac OS X: fixed hanging threads
1076 - Windows: disabled the previous thread fix on non-Mac systems, as
1077 it caused hanging threads on Windows
1078 - Fixed possible crashes due to corrupted MIDI/audio device list
1079 after MIDI/audio device creation failure
1080 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1081 instruments were uselessly precached with zero samples, however it still
1082 took the full preloading time and on 1st program change the respective
1083 instrument was completely reloaded again.
1084 - fixed handling of rapid bank select and program change messages
1085 sent to the same sampler channel (patch from the Open Octave
1086 project, slightly adjusted)

1105 crashes and noise on such transitions).
1106 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1107 (fixes #208)
1108 - Fixed bug in LSCP grammar definition which caused a statement like
1109 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1110 practically irrelevant, however it caused problems with the new LSCP
1111 shell's auto completion feature).
1112 - Fixed MIDI program change messages being ignored if quickly executed
1113 after each other (fixes #231).
1115 Version 1.0.0 (31 July 2009)
1117 * packaging changes:
1118 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

1131 directory above)
1132 - configure script fix: removed unconditional use of SSE
1133 - fixed building with sqlite installed in a non-standard directory
1134 - when cross-compiling, don't try to create instruments.db
1135 - fix for new mingw-w64 version, which has usleep
1137 * general changes:
1138 - bugfix: on some POSIX systems instrument editor plugins refused to
1139 load as we used a non-portable Linux specific struct field
1140 (fixes bug #70, patch by Ronald Baljeu)
1141 - fixed endless loop which occured when loading an instrument editor
1142 plugin DLL on Windows systems failed
1143 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1144 - optimized the SynchronizedConfig class so it doesn't wait
1145 unnecessarily long after an update

1147 events (e.g. to highlight the pressed keys on the virtual keyboard
1148 of gigedit)
1149 - added support for triggering notes by instrument editors (see above)
1150 - be verbose on DLL load errors (on Linux)
1151 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1152 is only used by very few systems, most pick the int math
1153 implementation, which is usually faster)
1154 - fixes for audio drivers with varying buffer sizes
1155 - experimental support for running LinuxSampler as a DSSI, LV2 and
1156 VST plugin
1157 - notification events for stream/voice count statistics are now sent

1160 multi-core and multi-cpu systems
1161 - maximum voices and disk streams can now be altered at runtime
1162 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1163 - automatic stacktrace mechanism is now turned off by default and can
1164 be switched on by command line option "--stacktrace" (the automatic
1165 stacktrace mechanism seems to be broken on most systems at the moment)
1166 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1167 a pointer to the launched InstrumentEditor object
1168 - added optional 3rd party user data parameter for following
1169 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1170 InstrumentEditor::Launch(),
1171 InstrumentManager::LaunchInstrumentEditor()
1172 - theoretical fix: made SynchronizedConfig follow C++0x memory
1173 model more strictly
1174 - fixes for using large audio device buffers
1175 - Windows: add the installation directory to the DLL search path
1176 when loading an editor plugin (solves problems with VST and
1177 gigedit on systems with other GTK versions installed)
1178 - updated linuxsampler man page
1180 * audio driver:
1181 - removed the nonsense audio channel constraint (which was hard coded to
1182 max. 100 audio channels) for most audio drivers
1183 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1184 opposed to the LSCP specs
1185 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1186 reflected the wrong value
1187 - fixed a memory management bug in ASIO driver
1188 - Makefile fix: JACK_CFLAGS wasn't used
1189 - JACK: use jack_client_open instead of the deprecated
1190 jack_client_new
1191 - added (experimental) CoreAudio driver

1196 win64)
1197 - VST: added support for sample rate and buffer size changes
1198 - VST: close editor (Fantasia) when the VST is removed
1199 - VST: avoid opening Fantasia more than once for each VST instance
1200 - VST: export main function as "main" on Linux too (fix for
1201 energyXT)
1202 - VST: changed number of output channels from one stereo to 16
1203 stereo
1204 - added channel routing, fxsends and midi maps to the settings
1205 stored in the plugin state
1206 - performance optimization of AudioChannel::MixTo() and
1207 AudioChannel::CopyTo() methods using GCC vector exensions
1208 (if available)
1209 - ASIO fixes: avoid initializing the device twice, avoid throwing
1210 exception when getting parameters from a disconnected device
1212 * MIDI driver:
1213 - added JACK MIDI driver
1214 - dispatch bank select as ordinary CC as well, the user might seriously
1215 want to (mis)use it for some purpose ("fixed" in all current MIDI
1216 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1217 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1218 CoreMidi or AU
1219 - fixed mingw-w64 compilation error in MME driver
1220 - made program change handling in MIDI thread real-time safe by
1221 moving the logic to a non-RT thread
1222 - fixed minor memory leak in ALSA driver

1225 - avoid time consuming samples scanning when adding instruments
1226 to the instruments database
1227 - added support for handling lost files in the instruments database

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