Added new LFO implementations:

* Added int math square LFO implementation.

* Added int math saw LFO implementation.

* Added numeric complex nr sine LFO implementation.

* Added public API C++ class "LFO", which is a cluster class
  encapsulating all the sampler's LFO implementations to be used by
  3rd party applications (e.g. by Gigedit).

* Marked class LFOTriangleDiHarmonic as deprecated
  (will be removed in future).

* Added LFOAll.h which includes all LFO implementation's header files.

* Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
  algorithm (since result of 2nd run was not accumulated).

* Added benchmark for saw wave (benchmarks/saw.cpp).

* Added benchmark for sine wave (benchmarks/sine.cpp).

* Added benchmark for square wave (benchmarks/square.cpp).

* Increased amount of benchmarks runs by factor 6 to achieve benchmark
  times which are large enough on modern systems.

* Cleanup of LFO APIs.

* Bumped version (2.1.1.svn18).

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

449 of its possible parameter selections.
450 - Fixed a bunch of scheduler time related bugs.

458 "change_tune_time()" respectively: now tuning/volume changes are only
459 assigned (without delay) immediately to a new note if the respective
460 timing function has not been called before, otherwise the volume/tuning

471 - Implemented built-in script function "change_vol_curve()".
472 - Implemented built-in script function "change_tune_curve()".
473 - built-in "play_note()" function now supports a sample playback start
474 offset with argument 3, where special value -1 means to use the regular
475 sample offset as defined by the instrument file.
476 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
477 - Built-in variable $EVENT_NOTE is now a read-only variable.
478 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
479 - built-in "play_note()" function now accepts -2 for its fourth argument
480 (note duration) which means the life time of the note shall be sticked
481 to the requested note number of argument 1.
482 - Fix: built-in "play_note()" function now returns 0 as result value if
483 -1 was passed for its fourth argument (note duration) and the respective
484 parent note is already gone.
485 - Implemented built-in script function "change_play_pos()".
486 - NKSP language: Added support for user declared const array variables.
487 - NKSP language: Raise parser warning if array variable is accessed with
488 an index that exceeds the array's size.
489 - NKSP language fix: Unknown characters were not handled correctly.
490 - NKSP language: Added support for "synchronized .. end synchronized"

495 "init" event handlers.
496 - Print a time stamp along to each call of built-in function "message()".
497 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
498 to retrieve all code blocks filtered out by the preprocessor.

506 - Added built-in constant $CALLBACK_STATUS_RUNNING.
507 - Removed max. value limitation of built-in functions "change_attack()",
508 "change_decay()" and "change_release()" to i.e. allow passing 2000000
509 for doubling the respective time.
510 - NKSP script editor syntax highlighting API: Fixed app termination due
511 to a lexer start condition stack underrun.
512 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
513 USE_CODE_IF_NOT() preprocessor statements.
514 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
515 can be set to disable all subsequent built-in "message()" function calls
516 on preprocessor level.
517 - Implemented built-in script function "change_sustain()".

534 is now optional, if it is missing, then a default location is used.
535 - Added support for scanning SFZ (.sfz) files.
536 - Added support for scanning Sound Font (.sf2) files.

578
579 * general changes:
580 - Refactoring: moved the independent code from
581 the Gigasampler format engine to base classes
582 - command line option '--profile' is currently disabled, since the
583 respective profiling code is currently broken
584 - Introduced support for optional environment variable
585 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
586 where the sampler shall look for instrument editor plugins
587 (patch by Luis Garrido, slightly modified).
588 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
589 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
590 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
591 note (in this implementation of the sampler its simply hard routed to
592 the 1st effect send of the sampler channel, no matter what the actual
593 effect type is)
594 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
595 note (in this implementation of the sampler its simply hard routed to
596 the 2nd effect send of the sampler channel, no matter what the actual
597 effect type is)
598 - implemented support for internal LADSPA effects
599 - raised limit of program change queue from 100 to 512
600 (as suggested by Alex Stone)
601 - implemented sine LFO, pulse LFO and saw LFO
602 - experimental support for per voice equalization
603 - added command line option --exec-after-init
604 - Introduced new C++ API method:
605 EngineChannel::InstrumentFileName(int index)
606 allowing to retrieve the whole list of files used for the loaded
607 instrument on an engine channel (a.k.a. part). Some GigaStudio
608 instruments for example are splitted over several files like
609 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
610 - Added new C++ API method Sampler::GetGlobalMaxVoices().
611 - Added new C++ API method Sampler::GetGlobalMaxStreams().
612 - Added new C++ API method Sampler::SetGlobalMaxVoices().
613 - Added new C++ API method Sampler::SetGlobalMaxStreams().
614 - Various "const" and "restrict" optimizations.
615 - all engines: add pan CC value to instrument pan parameter before
616 applying panning, instead of using two separate pan functions in
617 series (#182)
618 - added a lock guard class for exception safe mutex handling and
619 used it everywhere appropriate
620 - Immediately apply scale tuning changes to active voices.
621 - Exposed scale tuning to C++ API (along to the already existing standard
622 SysEx way).
623 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
624 and broken for ppc64. (Seq_cst loads and stores are actually not
625 used in LS, so the bug wasn't noticable.)
626 - lsatomic.h: added ARMv7 support
627 - Added support for multiple MIDI input ports per sampler channel (and
628 added various new C++ methods for this new feature / design change, old
629 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
630 as deprecated but are still there and should provide full behavior
631 backward compatibility).
632 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
633 unsafe and caused compilation error with clang 2.x).
634 - Bugfix: only process the latest MIDI program change event.
635 - Introducing the LSCP shell, which provides convenient control of the
636 sampler from the command line by providing LSCP aware features.
637 - VirtualMidiDevice: Added support for program change.
638 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
639 - VirtualMidiDevice: Added support for pitch bend.
640 - Aftertouch: extended API to explicitly handle channel pressure and
641 polyphonic key pressure events (so far polyphonic pressure was not
642 supported at all, and channel pressure was rerouted as CC128 but not
643 used so far).
644 - Added initial support for real-time instrument scripts. The script VM
645 code is shared by all sampler engine implemementations, however only the
646 gig file format currently provides support for storing instrument scripts
647 (as LinuxSampler extension to the original GigaStudio 4 format).
648

654 key
655 - bugfix: pitch LFO controller "internal+aftertouch" was broken
656 - bugfix: filter keyboard tracking was broken
657 - filter performance fix (an unnecessary copy was made of the
658 filter parameters in each sub fragment)
659 - handle special case when pan parameter in gig file has max or
660 min value
661 - Exclusive Groups: don't ever stop voices of the same note,
662 doesn't sound naturally with a drumkit
663 - fixed EG1 modulation when attack or release is zero
664 - Fixed support for 'aftertouch' attenuation controller.
665 - Fixed crash that happened with velocity split sounds under certain
666 conditions (see also previous commit on libgig).
667 - fixed behaviour of filter LFO
668
669 * SFZ format engine:

699 - added support for loop_mode=one_shot
700 - fixed playback of 16 bit wav files on big endian CPUs
701 - added support for Ogg Vorbis sample files
702 - use loop markers from sample file if loop_start and loop_end are
703 not set in sfz file
704 - implemeted filters. Filter types: lowpass, bandpass, bandreject
705 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
706 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
707 cutoff_cc, cutoff_chanaft.
708 - bugfix: zero ampeg_sustain didn't work

844 - AU bugfix: failed to destroy its audio/MIDI devices
845 - Listen to all interfaces on Mac OS X (INADDR_ANY)
846 - VST bugfix: If the host called resume() before and after
847 changing sample rate or block size, the number of channels was
848 incorrectly set to two. This caused silence in Cubase 5.
849 - save engine type (gig, sfz or sf2) in plugin state
850 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
851 64 bit Windows

861 loaded a second time (this time it's for Linux and Mac, previous
862 similar fix was for Windows)
863 - thread safety fixes for the instrument loading thread

868 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
869 port and audio channel routing for DSSI plugins are now visible.
870 - LV2: use urid and atom extensions instead of deprecated uri-map
871 and event
872 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

897 the driver will automatically connect to other CoreMIDI clients' ports
898 (e.g. external MIDI devices being attached to the Mac)
899 - added support for MIDI note on velocity filter
900 - CoreMIDI: fixed memory deallocation error
901 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
902 virtual keyboards in frontends / instrument editors being stuck.
903 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

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

1021 - Built-in script functions "ignore_event()", "note_off()" and
1022 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1023 (i.e. return value of new script function "by_marks()").
1024 - Pass/preserve polyphonic variable data from respective "note" event
1025 handler to "release" event handler.
1026 - Fixed crash when using built-in script function "by_marks()".
1027

1032 channel to a different engine type
1033 - fixed crash when deleting a sampler channel or changing engine
1034 type while an instrument load was in progress
1035 - bugfix: playing a note while changing the instrument could cause
1036 a crash, or give "Handing back unknown region" error messages
1037 - bugfix: calling SET VOICES (which Fantasia does on start and
1038 refresh) could cause instruments to be unloaded
1039 - Mac OS X: fixed name collision of enum in EffectControl and
1040 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1041 - Mac OS X: fixed hanging threads
1042 - Windows: disabled the previous thread fix on non-Mac systems, as
1043 it caused hanging threads on Windows
1044 - Fixed possible crashes due to corrupted MIDI/audio device list
1045 after MIDI/audio device creation failure
1046 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1047 instruments were uselessly precached with zero samples, however it still
1048 took the full preloading time and on 1st program change the respective
1049 instrument was completely reloaded again.
1050 - fixed handling of rapid bank select and program change messages
1051 sent to the same sampler channel (patch from the Open Octave
1052 project, slightly adjusted)
1053 - fixed crash when trying to create an effect instance with controls
1054 which min and/or max values depend on the sample rate

1067 playing a note in a key group
1068 - fixed erroneous error message piping in VoiceBase.h
1069 (labelled "Disk stream not available in time")
1070 - Update effects on sample rate & period size changes (to avoid
1071 crashes and noise on such transitions).
1072 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1073 (fixes #208)
1074 - Fixed bug in LSCP grammar definition which caused a statement like
1075 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1076 practically irrelevant, however it caused problems with the new LSCP
1077 shell's auto completion feature).
1078 - Fixed MIDI program change messages being ignored if quickly executed
1079 after each other (fixes #231).
1080
1081 Version 1.0.0 (31 July 2009)
1082
1083 * packaging changes:
1084 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1085 causing e.g. the libgig test to fail when
1086 "./configure --disable-jack-driver" was used
1087 (patch by Alexis Ballier)
1088 - fixed compilation with gcc 4.3
1089 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1094 - minor fix in configure for mmsystem.h detection on MinGW
1095 - Windows: look for editor plugins and Fantasia using base
1096 directory of liblinuxsampler dll (look in the same directory and one
1097 directory above)
1098 - configure script fix: removed unconditional use of SSE
1099 - fixed building with sqlite installed in a non-standard directory
1100 - when cross-compiling, don't try to create instruments.db
1101 - fix for new mingw-w64 version, which has usleep
1102
1103 * general changes:
1104 - bugfix: on some POSIX systems instrument editor plugins refused to
1105 load as we used a non-portable Linux specific struct field
1106 (fixes bug #70, patch by Ronald Baljeu)
1107 - fixed endless loop which occured when loading an instrument editor
1108 plugin DLL on Windows systems failed
1109 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1110 - optimized the SynchronizedConfig class so it doesn't wait
1111 unnecessarily long after an update
1112 - added support for notifying instrument editors on note-on / note-off
1113 events (e.g. to highlight the pressed keys on the virtual keyboard
1114 of gigedit)
1115 - added support for triggering notes by instrument editors (see above)
1116 - be verbose on DLL load errors (on Linux)
1117 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1118 is only used by very few systems, most pick the int math
1119 implementation, which is usually faster)
1120 - fixes for audio drivers with varying buffer sizes
1121 - experimental support for running LinuxSampler as a DSSI, LV2 and
1122 VST plugin
1123 - notification events for stream/voice count statistics are now sent
1124 only when there are actual changes
1125 - added memory ordering constraints to improve stability on
1126 multi-core and multi-cpu systems
1127 - maximum voices and disk streams can now be altered at runtime
1128 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1129 - automatic stacktrace mechanism is now turned off by default and can
1130 be switched on by command line option "--stacktrace" (the automatic
1131 stacktrace mechanism seems to be broken on most systems at the moment)
1132 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1133 a pointer to the launched InstrumentEditor object
1134 - added optional 3rd party user data parameter for following
1135 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1136 InstrumentEditor::Launch(),
1137 InstrumentManager::LaunchInstrumentEditor()
1138 - theoretical fix: made SynchronizedConfig follow C++0x memory
1139 model more strictly
1140 - fixes for using large audio device buffers
1141 - Windows: add the installation directory to the DLL search path
1142 when loading an editor plugin (solves problems with VST and
1143 gigedit on systems with other GTK versions installed)
1144 - updated linuxsampler man page
1145
1146 * audio driver:
1147 - removed the nonsense audio channel constraint (which was hard coded to
1148 max. 100 audio channels) for most audio drivers
1149 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1150 opposed to the LSCP specs
1151 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1152 reflected the wrong value
1153 - fixed a memory management bug in ASIO driver
1154 - Makefile fix: JACK_CFLAGS wasn't used
1155 - JACK: use jack_client_open instead of the deprecated
1156 jack_client_new
1157 - added (experimental) CoreAudio driver
1158 - applied old fixes to the ASIO driver that were included in the
1159 previous binary release but accidentally never committed to CVS
1160 (fixes #117)
1161 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1162 win64)
1163 - VST: added support for sample rate and buffer size changes
1164 - VST: close editor (Fantasia) when the VST is removed
1165 - VST: avoid opening Fantasia more than once for each VST instance
1166 - VST: export main function as "main" on Linux too (fix for
1167 energyXT)
1168 - VST: changed number of output channels from one stereo to 16
1169 stereo
1170 - added channel routing, fxsends and midi maps to the settings
1171 stored in the plugin state
1172 - performance optimization of AudioChannel::MixTo() and
1173 AudioChannel::CopyTo() methods using GCC vector exensions
1174 (if available)
1175 - ASIO fixes: avoid initializing the device twice, avoid throwing
1176 exception when getting parameters from a disconnected device
1177
1178 * MIDI driver:
1179 - added JACK MIDI driver
1180 - dispatch bank select as ordinary CC as well, the user might seriously
1181 want to (mis)use it for some purpose ("fixed" in all current MIDI
1182 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1183 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1184 CoreMidi or AU
1185 - fixed mingw-w64 compilation error in MME driver
1186 - made program change handling in MIDI thread real-time safe by
1187 moving the logic to a non-RT thread
1188 - fixed minor memory leak in ALSA driver
1189
1190 * instruments database:
1191 - avoid time consuming samples scanning when adding instruments
1192 to the instruments database
1193 - added support for handling lost files in the instruments database
1194 - Implemented option for adding instruments in separate directories
1195 in the instruments database
1196 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1197 - work-around for missing fnmatch function on Windows to make
1198 instrument database compilable
1199 - added instrument database support on Windows
1200 works with both standalone mode and VST plugin.
1201 the instruments DB file is located in
1202 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1203 databases for each windows user
1204 if no DB is present it automatically creates the .linuxsampler subdir
1205 and then creates an empty DB
1206 - fixed recursive import, which was broken on Windows
1207
1208 * Gigasampler format engine:
1209 - fixed a memory leak that could happen when a channel was deleted
1210 while notes were playing
1211 - made it possible to load an instrument even if the audio thread
1212 isn't running
1213 - added partial support for the "Controller Triggered" MIDI rule,
1214 enough for piano gigs with pedal noise samples
1215 - minor fix: only mark FX sends as being modified if really the
1216 respective FX send MIDI controller was used
1217 - added support for GM global device volume SysEx message
1218 (can be selected at compile time to either apply globally to the
1219 whole sampler [default] or only to the sampler channels that are
1220 connected to the respective MIDI input port the SysEx message arrived
1221 on)
1222 - bugfix: notes triggered at position 0 in the audio buffer were
1223 sometimes wrongly killed in the same buffer, causing no sound to
1224 be played
1225 - added support for chromatic / drumkit mode Roland GS Sysex message
1226 which is usally used to switch a part between chromatic sounds and
1227 drumkit sounds (as opposed to their common default setting of MIDI
1228 part 10 being a drumkit part and all other ones chromatic parts), in
1229 LS however one can switch between the first 16 MIDI instrument maps
1230 defined for the sampler
1231 - made it possible to create multiple sample channels even if the
1232 audio thread isn't running
1233 - fixed crash when removing channel with active voices (#116)
1234 - bugfix: on sample reference changes (instrument editor), only
1235 un-cache the respective sample if it's really not used by any
1236 sampler engine anymore
1237 - re-cache samples in case they were changed by an instrument editor,
1238 e.g. when a sample was added while playing (#82)
1239 - fixed hanging notes which occured when note-off event had the exact
1240 same time stamp as the voice's note-on event and occured both in the
1241 same audio fragment cycle (fixes bug #112)
1242 - added support for the "fine tune" and "pitch bend range"
1243 instrument-level gig parameters
1244 - fixed minor artifacts in pitch bend handling
1245 - added support for GS Reset SysEx message
1246 - allow gig files to use unlimited downward pitch shifting
1247 - added a limit check for upward pitch shifting
1248 - bugfix: sometimes, when playing a note twice fast, the second
1249 note was silent
1250 - fixed crash happening when a pitch bend event arrived at the
1251 same time a new instrument was loading
1252
1253 * LSCP server:
1254 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1255 react on MIDI data arriving on certain sampler channels (so far only
1256 Note-On and Note-Off events are sent via this LSCP event)
1257 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1258 react on MIDI data arriving on certain MIDI input devices (so far only
1259 Note-On and Note-Off events are sent via this LSCP event)
1260 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1261 SET DB_INSTRUMENT FILE_PATH
1262 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1263 frontends to send MIDI messages to specific sampler channel
1264 - added two additional fields to GET FILE INSTRUMENT INFO command -
1265 KEY_BINDINGS and KEYSWITCH_BINDINGS
1266 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1267 was incorrect
1268 - Optimized the retrieval of the MIDI instrument mappings
1269 - added new LSCP command "SET VOICES" to globally alter the maximum
1270 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1271 be triggered respectively
1272 - added new LSCP command "SET STREAMS" to globally alter the maximum
1273 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1274 which will be triggered respectively
1275 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1276 a gigedit file dialog is opened)
1277 - close all connections when LSCPServer is deleted
1278 - hard close of all sockets on exit
1279 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1280 driver
1281
1282 * Bug fixes:
1283 - fixed a crash which occurs when removing a sampler channel waiting
1284 to start instrument loading after another channel
1285 - fixed a crash which occurs when removing a sampler channel with
1286 instrument loading in progress (bug #113)
1287 - fixed termination caused by uncaught exception when adding MIDI
1288 instrument with PERSISTENT load mode
1289 - fixed possible iterator invalidations when resetting the sampler
1290 - fixed memory leaks when issuing the following LSCP commands:
1291 GET AUDIO_OUTPUT_DRIVER INFO
1292 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1293 GET MIDI_INPUT_DRIVER INFO
1294 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1295 - fixed possible compilation error when sqlite is not present
1296 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1297 - fixed crash when changing the audio output device of a sampler
1298 channel with loaded instrument and start playing notes
1299 - fixed endless loop in Engine::SuspendAll() (bug #120)
1300 - fixed a low-level atomic load function that was broken on 64-bit
1301 PowerPC, which probably could cause crashes on that platform
1302 - fixed a memory management error which could cause a crash when a
1303 plugin was unloaded
1304 - bugfix: two private structs had the same name, which could cause
1305 problems if the linker chose the wrong constructor
1306 - fixed low-level ConditionServer usage bug that caused lockups on
1307 Windows
1308
1309
1310 Version 0.5.1 (6 December 2007)
1311
1312 * packaging changes:
1313 - added autoconf checks for pthread library
1314 - added autoconf check for pthread bug found on certain NPTL-enabled
1315 glibc versions (see Gentoo bug report #194076)
1316 - added autoconf checks for MS Windows
1317
1318 * general changes:
1319 - bugfix: the thread used by an editor plugin didn't die when the
1320 editor closed
1321 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1322 out all the space. operator--() did not apply size_mask after
1323 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1324 order to avoid problems with the _NonVolatileReader functions.
1325 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1326 GetWriteSpace(). Since this function is currently only used in
1327 the stream's qsort() compare function, it didn't trigger any
1328 bugs.
1329 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1330 24bit mode too. Faster method to read 24bit words on little
1331 endian machines (x86): replaced 3 byte reads + shifts with a 1
1332 unaligned 32bit read and shift
1333 - experimental support for MS Windows (MIDI input via MME, AUDIO
1334 output via ASIO)
1335 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1336 - support for monitoring the total number of active disk streams
1337 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1338 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1339
1340 * AUDIO driver:
1341 - added Windows ASIO low latency audio driver
1342
1343 * MIDI driver:
1344 - added MME Windows MIDI driver
1345
1346 * LSCP server:
1347 - added support for Windows style path / filenames, however with
1348 forward slash path separators instead of backslash
1349 (i.e. "C:/foo/bar.gig")
1350 - allow naughty liblscp to send non-string device parameters within
1351 apostrophes as well
1352 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1353 "LIST FILE INSTRUMENTS <file>" and
1354 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1355 about an arbitrary instrument file on the system where the sampler is
1356 running on
1357
1358 Version 0.5.0 (15 October 2007)
1359
1360 * packaging changes:
1361 - config.h is not going to be installed along with liblinuxsampler's
1362 API header files anymore
1363 - only the API relevant header (and source) files will be exported to
1364 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1365 - added completely new XCode project files for Mac OSX which is now
1366 capable to execute our autoconf environment, thus no need anymore
1367 to maintain the compile time configuration file (osx/version.h) for
1368 OSX manually (patch by Toshi Nagata)
1369 - fixed buggy boolean --enable-foo / --disable-foo configure script
1370 parameters
1371 - global.h now only covers global definitions that are needed for the
1372 C++ API header files, all implementation internal global definitions
1373 are now in global_private.h
1374 - atomic.h is not exposed to the C++ API anymore
1375 - no need to include config.h anymore for using LS's API header files
1376 - fixed warnings in API doc generation
1377
1378 * general changes:
1379 - replaced the old, confusing MIDI program change mechanism by a
1380 flexible MIDI instrument mapper which allows to map arbitrary
1381 (MIDI bank, MIDI program) pairs with arbitrary
1382 (engine type, instrument file, file index) triplets which will be
1383 loaded on the respective channel when such MIDI program change
1384 messages arrive, beside that, each entry allows to define a life-time
1385 strategy for the instrument, so the user can define whether the
1386 instrument should i.e. be permanently loaded (to be able to switch
1387 quickly among sounds) or i.e. loaded just on demand when the
1388 respective program change arrives (to safe RAM space), as well as a
1389 global volume factor for each entry, so the user can adjust the volume
1390 dynamic of his mapped instrument collection without having to modify
1391 the instrument files, also one can manage arbitrary amount of such
1392 MIDI instrument maps and assign each sampler channel individually
1393 a certain map, so that i.e. separation of normal instruments and
1394 drumkits is possible
1395 - new notification events for tracking changes to audio/MIDI devices,
1396 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1397 - sampler was limited to load max. 200 instruments in the background
1398 due to a constant size RingBuffer FIFO which is now replaced by a
1399 dynamic (unlimited) size std::list FIFO
1400 - added FX sends, these allow to route audio signals to arbitrary audio
1401 output channels for being processed by external effect processors
1402 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1403 controllers
1404 - global (sampler wide) volume can now be controlled at runtime
1405 - Implemented new, improved notification system
1406 - fixed compilation errors regarding OSX
1407 (patch by Toshi Nagata)
1408 - implemented instruments database
1409 - added support for escape sequences to the instruments database
1410 - added highly experimental support for on-the-fly instrument editing
1411 within the sampler's process (by using instrument editor plugins),
1412 you'll notice the new "Registered instrument editors:" message on
1413 startup, added a new LSCP command:
1414 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1415 to spawn a matching instrument editor for the instrument on the
1416 given sampler channel, the plugin path can be overridden at compile
1417 time with ./configure --enable-plugin-dir=/some/dir
1418 - added experimental code for synchronizing instrument editors hosted
1419 in the sampler's process to safely edit instruments while playing
1420 without a crash (hopefully) by either suspending single regions
1421 wherever possible or if unavoidable whole engine(s)
1422 - fixed several issues in fundamental "Thread" class: set scheduling
1423 policy and priority on thread level, set a minimum stack size for
1424 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1425 threads simply inherited properties of starting thread instead of
1426 setting their own policy and priority
1427 - minor fix in our automatic stack trace mechanism on crashes, the
1428 main process did not wait for the stack trace process to finish
1429 its output
1430 - fixed some minor memory leaks
1431 - reenabled assembly features support, at the moment only for
1432 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1433 - minor assembly fix in x86 features detection (don't use the PIC
1434 register, to avoid relocations in the text segment at runtime)
1435 - POSIX callback functions of Thread.h are hidden
1436
1437 * MIDI driver:
1438 - dispatch bank select (MSB and LSB) messages
1439
1440 * audio driver:
1441 - the ALSA audio output driver parameters now reflect the correct
1442 parameter value ranges for the respective selected sound card
1443 (patch by Till Wimmer, a bit fixed and extended)
1444
1445 * Gigasampler format engine:
1446 - if a filter is used and EG2 finishes before EG1, let the voice
1447 die when EG2 has finished (this fixes a problem with clicks and
1448 voice starvation for some gigs)
1449 - playback is no longer disabled during instrument loading
1450 - all notes playing on a channel that changes its instrument keep
1451 playing with the old instrument until they get a note off
1452 command
1453 - EG fix: a release value of zero could cause noises or crash
1454 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1455 - EG fine tuning: when attack is zero the EG starts at a level
1456 above max sustain level, which means that there is a decay phase
1457 even if sustain is 100%
1458 - more EG fixes: the level could sometimes go below zero and cause
1459 noises or crashes
1460 - minor fix of EGDecay (patch by Toshi Nagata)
1461 - fixed compiler error when --enable-override-filter-type was
1462 supplied to the configure script (fixes #46)
1463 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1464 instead of a fix value
1465 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1466 127 (solo mode) only kill voices if the respective mode really
1467 changed
1468
1469 * LSCP server:
1470 - fixed compile time error for old Bison versions
1471 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1472 - parser now supports extended ASCII character set
1473 (up to ASCII code 255, i.e. includes now umlauts and accents)
1474 - filename arguments in LSCP commands now allow to use escape
1475 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1476 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1477 code value like \xf2) (fixes bug #24)
1478 - the following LSCP commands now also support escape sequences for at
1479 least one of their text-based parameters (i.e. name, description):
1480 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1481 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1482 "SET DB_INSTRUMENT_DIRECTORY NAME",
1483 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1484 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1485 "FIND DB_INSTRUMENT_DIRECTORIES"
1486 - returns verbose syntax errors (line and column where syntax error
1487 occured, the unexpected character and the actually expected, possible
1488 character(s), the latter only if less than 5 possibilities)
1489 - made sure that LSCP syntax is not affected by gigedit locale
1490 settings
1491 - bugfix regarding strings parameter lists: all comma separated lists
1492 of strings were treated as being one string containing commas
1493 (fixes #57)
1494
1495 * Bug fixes:
1496 - fixed crash occurring on certain LSCP scripts (Bug 39)
1497 - another thread safety fix for lscp "load engine" and "set
1498 channel audio output device"
1499 - fixed a crash which occurs when reassigning the same engine
1500 on a sampler channel with connected MIDI device
1501 - fixed a crash which occurs when changing the number of ports of a MIDI
1502 device connected to a sampler channel to number less then or equal
1503 to the index of the port to which the sampler channel is connected.
1504 - The previous bindings were not been disconnected when altering
1505 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1506 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1507 - The active stream/voice count statistic was incorrect.
1508 - notification events were not been sent for some sampler
1509 channel changes
1510 - added default min and max values to restrict the number of allowed
1511 audio output channels and MIDI input ports
1512 - the connection to the PCM interface is now closed when destroying
1513 an audio output device
1514 - files with slash in their path or filename could not be loaded
1515
1516 * test cases:
1517 - updated and fixed (haven't been touched in a while)
1518
1519 Version 0.4.0 (24 November 2006)
1520
1521 * packaging changes:
1522 - changed deprecated copyright attribute to license; added ldconfig
1523 to post-(un)install steps; added devel package for liblinuxsampler;
1524 to linuxsampler.spec (RPM)
1525 - install necessary development header files for allowing 3rd party
1526 applications to link against liblinuxsampler
1527 - liblinuxsampler's API documentation can be generated with 'make docs'
1528 (Doxygen required)
1529 - added benchmark to automatically detect the best triangle LFO
1530 implementation (currently either an integer math solution or a
1531 di-harmonic approximation), automatic detection can be overriden
1532 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1533 configure script argument though (mandatory for cross-compilation)
1534 - do not automatically pick optimized gcc flags if the user already
1535 provided some on his own (as CXXFLAGS)
1536 - added compile time option to disable processing of All-Notes-Off MIDI
1537 messages
1538 - added compile time options to allow disabling the various audio and
1539 MIDI drivers
1540 - fixed automatic GCC CPU switch detection on PPC
1541 (patch by Ebrahim Mayat)
1542
1543 * Gigasampler format engine:
1544 - extensive synthesis optimization
1545 (reimplementation of EGs and LFO(s), removed synthesis parameter
1546 prerendering and the synthesis parameter matrix in general, splitting
1547 each audio fragment into subfragments now where each subfragment uses
1548 constant pitch and filter coefficients. The volume coefficient is
1549 linearly interpolated inside a subfragment, unless
1550 --disable-interpolate-volume is set.)
1551 - fine tuning of the EG modulation parameters
1552 - improved filter cutoff calculation by adding support for the
1553 following gig parameters: Cutoff freq (used when no cutoff
1554 controller is defined), Control invert, Minimum cutoff, Velocity
1555 curve and Velocity range. The keyboard tracking now scales
1556 cutoff frequency instead of resonance.
1557 - added support for gig parameter Resonance.
1558 - fixed bug in sysex handling (patch by Juan Linietsky)
1559 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1560 which can be overridden with --enable-global-attenuation
1561 - EG fixes: made the length of "attack hold" stage more
1562 accurate. Release stage can now start before attack stage
1563 ends. Cancel release didn't work when sustain was zero. Attack
1564 time now has a minimal value to prevent clicks.
1565 - fixed pitch changes larger than one octave
1566 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1567 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1568 all modes can be altered via standard GM messages, that is CC5 for
1569 altering portamento time, CC65 for enabling / disabling portamento
1570 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1571 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1572 parameter) and crossfade
1573 - added support for the "attenuation controller threshold" gig
1574 parameter
1575 - added smoothing of volume changes caused by control change
1576 messages
1577 - sample loop parameters are now taken from the DimensionRegion
1578 instead of the wave chunk
1579 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1580 not equal to a power of two
1581 - reimplementation of the filter algorithm. The new filter is more
1582 accurate and supports all gig filter types, including bandreject
1583 and lowpass turbo.
1584 - real support for 24 bit samples - samples are not truncated to
1585 16 bits anymore
1586 - support for aftertouch (channel pressure, not polyphonic
1587 aftertouch)
1588 - LFO1 behaviour fixed (dampening from max volume instead of
1589 amplifying from 0)
1590
1591 * LSCP server:
1592 - fixed application exit on broken pipe error (fixes bug #20)
1593 - fixed the notification messages delay due to lack of
1594 network activity (fixes bug #26)
1595 - fixed parser bug which occured on space(s) within device parameters
1596 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1597
1598 * audio driver:
1599 - added aRts audio output driver (by no means RT safe)
1600
1601 * MIDI driver:
1602 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1603 messages several times instead of once
1604 - API extension for MIDI drivers which already supply exact time stamps
1605 for events (i.e. for offline rendering based MIDI drivers)
1606 - added checks for bad MIDI data
1607
1608 * linuxsampler application:
1609 - show available sampler engine types on startup
1610
1611 * general changes:
1612 - support for muting sampler channels and solo mode of the same, two new
1613 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1614 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1615 introduced for this, the behavior is the same like on a mixer console
1616 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1617 --enable-process-muted-channels which can be used to enable the
1618 processing of muted channels.
1619 - support for sostenuto pedal
1620 - support for monitoring the total number of active voices
1621 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1622 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1623 - fixed some memory management errors
1624 - fixed some concurrency problems that could lead to crashes when
1625 LSCP commands were executed
1626 - fixed crash when instrument loading failed previously on the same
1627 sampler channel (fixes bug #36)
1628
1629 Version 0.3.3 (15 July 2005)
1630
1631 * packaging changes:
1632 - fixed compilation with gcc 4.0
1633
1634 * Gigasampler format engine:
1635 - LFO preprocessing was performed even though the respective LFO was
1636 disabled by the instrument patch (minor efficiency fix)
1637 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1638 for volume ramp downs in the same fragment (needed for current voice
1639 stealing implementation) then simply inform the user with a warning
1640 about possible click sounds and reduce the volume ramp down
1641 appropriately instead of cancelling the audio device connection
1642
1643 Version 0.3.2 (24 June 2005)
1644
1645 * packaging changes:
1646 - updated autotools build files to compile on OS X
1647 (conditional compilation of CoreMIDI and MidiShare drivers)
1648 - hand-crafted assembly optimization code can be disabled with
1649 './configure --disable-asm' (definitely not recommended)
1650 - fixed 'make dist' rule to include all necessary files
1651 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1652 (due to 'dist-bzip2' automake option)
1653
1654 * Gigasampler format engine:
1655 - support for the gig parameters for "release velocity response" curves
1656 - fine tuning of the EGADSR envelope
1657 - volume of release triggered samples now depends on note-on velocity,
1658 note length and gig parameter "release trigger decay" instead of
1659 note-off velocity.
1660 - revised voice stealing
1661 (fixes crash and endless loop caused by voice stealing)
1662 - don't reset scale tuning on instrument or audio output device change
1663 - handle key group conflicts right at the beginning of each fragment
1664 instead of when the respective voice is actually launched
1665 (fixes undefined behavior if stolen voices belonged to a key group -
1666 this case was followed by a "killed voice survived" error message)
1667 - fixed minor issue with null/silence samples
1668 (those stole voices even though they don't need a voice at all which
1669 resulted in "voice stealing didn't work out" messages)
1670 - don't reset volume, pan, pitch and MIDI controller values on
1671 instrument or audio output device change
1672
1673 * LSCP server:
1674 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1675 - fixed LSCP event "CHANNEL_INFO" notification
1676 (e.g. did not notify on volume changes or MIDI program change events)
1677
1678 * linuxsampler application:
1679 - added command line parameters --lscp-addr and --lscp-port to override
1680 default IP address and port of LSCP server
1681
1682 Version 0.3.1 (24 May 2005)
1683
1684 * initial release
