NKSP: Introducing variable return type for built-in functions.

* Changed method signature VMFunction::returnType() ->
  VMFunction::returnType(VMFnArgs* args) to allow built-in
  functions to proclaim a different result value type depending
  on the arguments to be passed to the function.

* Built-in script function abs() optionally accepts and returns
  real number.

* Built-in script functions min() and max() optionally accept
  real number arguments and return real number as result in that
  case.

* Added real number test cases for the built-in abs(), min() and
  max() functions.

* Bumped version (2.1.1.svn7).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++11 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++11 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++11).
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
14 * Real-time instrument scripts:
15 - Added method ScriptVM::setExitResultEnabled() which allows to
16 explicitly enable the built-in exit() function to optionally accept
17 one function argument; the value of the passed exit() function
18 argument will then become available by calling
19 VMExecContext::exitResult() after script execution.
20 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 - Variable names, function names and preprocessor condition names must start
22 with a regular character (a-z or A-Z); starting them with a digit or
23 underscore is not allowed.
24 - NKSP parser fix: equal comparison operator "=" and not equal comparison
25 operator "#" must only accept integer operands.
26 - NKSP language: Implemented support for standard units like Hertz, seconds,
27 Bel including support for metric unit prefixes; so one can now e.g.
28 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31 - NKSP language: Introduced "final" operator "!" which is specifically
32 intended for synthesis parameter values to denote that the synthesis
33 parameter value is intended to be the "final" value for that synthesis
34 parameter that should explicitly be used by the engine and thus causing
35 the sampler engine to ignore all other modulation sources for the same
36 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37 variable or formula with this new "!" operator the expression is marked as
38 being "final".
39 - NKSP script editor API: Added support for detecting standard unit tokens
40 and their potential metric prefix token.
41 - NKSP language: Added support for NKSP real number literals and
42 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43 - NKSP language: Added support for NKSP real number (floating point) script
44 variables (declare ~foo).
45 - NKSP language: Added support for NKSP real number (floating point) array
46 script variables (declare ?foo[]).
47 - Built-in script function "message()" accepts now real number argument as
48 well.
49 - Added built-in script function "real_to_int()" and its short hand form
50 "int()" for casting from real number to integer in NKSP scripts.
51 - Added built-in script function "int_to_real()" and its short hand form
52 "real()" for casting from integer to real number in NKSP scripts.
53 - Allow built-in exit() function to potentially accept real number type
54 argument as well.
55 - Built-in script functions may have a different return type depending on
56 the arguments passed to the function.
57 - Built-in script function "abs()" optionally accepts and returns real
58 number.
59 - Built-in script functions "min()" and "max()" optionally accept real
60 number arguments and return real number as result in that case.
61
62 * test cases:
63 - Fixed compiler errors in test cases.
64 - Updated README for how to compile & run test cases.
65 - Updated test case
66 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
67 expected behaviour of the Mutex class implementation (recursive
68 mutex type).
69 - Added test cases for NKSP core language aspects and core built-in
70 functions.
71 - Fixed thread tests segfaulting on Linux.
72 - NKSP: Added real number test cases for built-in functions exit(),
73 int_to_real(), real(), real_to_int() and int(), as well as for the
74 plus, minus and negate language operators.
75
76 Version 2.1.1 (27 Jul 2019)
77
78 * Real-time instrument scripts:
79 - Fixed behavior of built-in NKSP functions change_sustain(),
80 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
81 and change_cutoff_release().
82
83 * general changes:
84 - Only play release trigger samples on sustain pedal up if this behaviour
85 was explicitly requested by the instrument (otherwise only on note-off).
86 - Fixed compiler warnings.
87 - Fixed compilation error when cross-compiling to Mac.
88 - FX Sends: Provide more useful error messages on routing problems
89 (see bug #169).
90 - LSCP doc: Be more clear describing the two distinct approaches
91 of using external vs. internal effects (see bug #169).
92 - "optional" class: Fixed comparison operators.
93
94 * Gigasampler/GigaStudio format engine:
95 - Format extension: If requested by instrument then don't play release
96 trigger sample on note-off events.
97
98 * SFZ format engine:
99 - Fixed memory leak when releasing samples
100 (fixes bug #307, patch by Jacek Roszkowski)
101 - Fixed potential crash when a sample is shared by more than one region
102 (fixes bug #308, patch by Jacek Roszkowski).
103 - Opcode 'sample': Added support for built-in sample '*silence'
104 (fixes bug #310, patch by Jacek Roszkowski).
105
106 Version 2.1.0 (25 Nov 2017)
107
108 * SFZ format engine:
109 - added support for <global>, <master> and #define (patch by Alby M)
110 - Removed code duplication in SFZ file loading code.
111 - Added support for sfz extension opcode 'script' which may be used to
112 load real-time instrument script file (NKSP script language).
113 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
114 - Fixed unintended volume fade-in of voices under certain conditions.
115 - sfz parser: allow missing space between header and opcode
116
117 * Gigasampler/GigaStudio format engine:
118 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
119 cutoff settings.
120 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
121 all if an up-pitch of more than 40 semi tones was requested (I don't
122 think there is any stock gig sound that requires this behavior to
123 resemble its original sound).
124 - Added support for controlling whether the individual EGADSR stages may
125 be aborted (as LinuxSampler extension to the original GigaStudio 4
126 format).
127
128 * general changes:
129 - fixed printf type errors (mostly in debug messages)
130 - use unique_ptr instead of auto_ptr when building with C++11
131 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
132 allowing to sort data efficiently in real-time safe manner.
133 - RTList class: added methods for moving/inserting elements to arbitrary
134 position within a list.
135 - RTList class: added method fromPtr() for creating an Iterator object from
136 a raw element pointer.
137 - Attempt to partly fix resetting engine channels vs. resetting engine, an
138 overall cleanup of the Reset*(), ConnectAudioDevice(),
139 DisconnectAudioDevice() API methods would still be desirable though,
140 because the current situation is still inconsistent and error prone.
141 - Active voices are now internally grouped to "Note" objects, instead of
142 being directly assigned to a keyboard key. This allows more fine graded
143 processing of voices, which is i.e. required for certain instrument
144 script features.
145 - Fix: Release trigger voices were not spawned on sustain pedal up
146 (CC #64) events.
147 - Fix: Release trigger voices can now also distinguish correctly between
148 note-off and sustain pedal up events.
149 - All engines: Increased ramp speed of volume smoother and pan smoother
150 (while slow rate of crossfade smoother is preserved) to allow quick
151 volume and pan changes by instrument scripts for instance.
152 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
153 properly and thus were ignored for certain uses.
154 - Added new C++ API method
155 VirtualMidiDevice::SendChannelPressureToSampler().
156 - windows, 32-bit: fixed potential crashes by making sure the stack in
157 sub threads is 16-byte aligned
158 - fixed numerous compiler warnings
159 - Fixed invalid (note-on) event ID being assigned to new Note objects.
160 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
161 fixes potential undefined behavior.
162 - Fixed Note object leak when triggering notes on keys which did not
163 have a valid sample mapped (fixes bug #252).
164 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
165 - linuxsampler binary fix: option --create-instruments-db ignored
166 subsequent optional argument due to glibc's implementation oddity
167 which expects a "=" sign, but no space between them.
168
169 * packaging changes:
170 - removed unnecessary dependency to libuuid
171 (originated by libgig's usage of it)
172 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
173 auto detect whether it (sh/c)ould output its messages in color.
174 - Debian: Fixed packaging error about invalid "Source-Version"
175 substitution variable.
176 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
177 - Debian: Added build dependency to libsqlite3-dev for building
178 linuxsampler with instruments DB support.
179
180 * Real-time instrument scripts:
181 - Implemented scheduler for delayed MIDI events and for suspended scripts.
182 - Built-in script function "wait()": implemented support for function's
183 "duration-us" argument, thus scripts using this function are now
184 correctly resumed after the requested amount of microseconds.
185 - Built-in script function "play_note()": implemented support for
186 function's "duration-us" argument, thus notes triggered with this
187 argument are now correctly released after the requested amount of
188 microseconds.
189 - Fix: script events were not cleared when engine channel was reset,
190 potentially causing undefined behavior.
191 - Fixed crash which happened when trying to reference an undeclared
192 variable.
193 - Built-in script function "play_note()": Added support for passing
194 special value -1 for "duration-us" argument, which will cause the
195 triggered note to be released once the original note was released.
196 - Instrument script classes now exported with the liblinuxsampler C++ API.
197 - Added new API method ScriptVM::syntaxHighlighting() which provides
198 a convenient syntax highlighting backend for external instrument
199 script editor applications.
200 - Added new C++ API class "ScriptVMFactory".
201 - Extended parser issues to provide not only first line and first
202 column, but also last line and last column of issue (thus marking
203 the precise span of the issue within the source code).
204 - Reload script automatically after being modified by an instrument
205 editor.
206 - NKSP language grammar correction: allow empty event handler bodies
207 like "on note end on".
208 - Implemented built-in script function "change_vol()".
209 - Implemented built-in script function "change_tune()".
210 - Implemented built-in script function "change_pan()".
211 - Implemented built-in script function "change_cutoff()".
212 - Implemented built-in script function "change_reso()".
213 - Implemented built-in script function "event_status()".
214 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
215 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
216 "event_status()" function.
217 - NKSP language: Added support for bitwise operators ".or.", ".and."
218 and ".not.".
219 - NKSP language scanner: Fixed IDs matching to require at least one
220 character (i.e. when matching function names or variable names).
221 - NKSP language scanner: disabled unusued rules.
222 - Fixed behavior of play_note() and note_off() functions which must
223 be distinguished engine internally from "real" MIDI note on/off
224 events in order to avoid misbehaviors like hanging notes.
225 - Implemented built-in script variable "$KSP_TIMER".
226 - Implemented built-in script variable "$NKSP_REAL_TIMER".
227 - Implemented built-in script variable "$NKSP_PERF_TIMER".
228 - Implemented built-in script variable "$ENGINE_UPTIME".
229 - Implemented built-in script function "inc()".
230 - Implemented built-in script function "dec()".
231 - NKSP language fix: division expressions were evaluated too often.
232 - NKSP language fix: string concatenation operator was right
233 associative instead of left (to right).
234 - NKSP language correction: allow empty statements in entire language
235 (i.e. "if end if").
236 - Implemented built-in script function "stop_wait()".
237 - Implemented built-in script variable "$NI_CALLBACK_ID".
238 - Implemented built-in script variable "$NI_CALLBACK_TYPE".

244 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
245 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
246 - NKSP Language: Added support for user defined script functions.
247 - Implemented built-in script function "change_attack()".
248 - Implemented built-in script function "change_decay()".
249 - Implemented built-in script function "change_release()".
250 - Fixed all change_*() built-in script functions to apply their
251 synthesis parameter changes immediately in case the respective note
252 was triggered at the same time, instead of scheduling the parameter
253 change, especially because it would cause some parameter types's
254 changes either to be ramped (i.e. change_vol()) or other types even
255 to have not effect at all (i.e. change_attack()).
256 - Implemented built-in script function "sh_left()".
257 - Implemented built-in script function "sh_right()".
258 - Implemented built-in script function "min()".
259 - Implemented built-in script function "max()".
260 - NKSP Fix: "init" event handler was not always executed when a script
261 was loaded.
262 - NKSP built-in wait() script function: abort script execution if
263 a negative or zero wait time was passed as argument (since this is
264 a common indication of a bug either of the script or even of the
265 engine, which could lead to RT instability or even worse).
266 - ScriptVM: Implemented automatic suspension of RT safety
267 threatening scripts.
268 - Provide more user friendly error messages on syntax errors.
269 - Fixed NKSP parser warning "Not a statement" when assigning an
270 initializer list to an array variable.

274 - Implemented built-in script function "change_amp_lfo_freq()".
275 - Implemented built-in script function "change_pitch_lfo_depth()".
276 - Implemented built-in script function "change_pitch_lfo_freq()".
277 - Implemented built-in script function "change_vol_time()".
278 - Implemented built-in script function "change_tune_time()".
279 - Implemented built-in script function "fade_in()".
280 - Implemented built-in script function "fade_out()".
281 - Fixed acceptance of wrong data type of parameters passed to built-in
282 script functions "change_vol()", "change_tune()", "change_pan()",
283 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
284 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
285 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
286 - Added built-in script function "get_event_par()" and implemented some
287 of its possible parameter selections.
288 - Added built-in script function "set_event_par()" and implemented some
289 of its possible parameter selections.
290 - Fixed a bunch of scheduler time related bugs.
291 - Fixed polyphonic variables not being reset to zero after usage.
292 - Built-in "ignore_event()" function: argument is now optional, like with
293 built-in function "ignore_controller()".
294 - Implemented built-in script function "change_velo()".
295 - Implemented built-in script function "change_note()".
296 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
297 intuitive behavior if used in combination with "change_vol_time()" or
298 "change_tune_time()" respectively: now tuning/volume changes are only
299 assigned (without delay) immediately to a new note if the respective
300 timing function has not been called before, otherwise the volume/tuning
301 changes are automatically faded (before, only the event's time stamp was
302 relevant).
303 - Implemented built-in script function "array_equal()".
304 - Implemented built-in script function "search()".
305 - Implemented built-in script function "sort()".
306 - NKSP Fix: Never suspend "init" event handlers.
307 - Implemented built-in script function "same_region()" (currently only
308 available for gig format engine).
309 - Added built-in script constant "$NKSP_LINEAR".
310 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
311 - Implemented built-in script function "change_vol_curve()".
312 - Implemented built-in script function "change_tune_curve()".
313 - built-in "play_note()" function now supports a sample playback start
314 offset with argument 3, where special value -1 means to use the regular
315 sample offset as defined by the instrument file.
316 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
317 - Built-in variable $EVENT_NOTE is now a read-only variable.
318 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
319 - built-in "play_note()" function now accepts -2 for its fourth argument
320 (note duration) which means the life time of the note shall be sticked
321 to the requested note number of argument 1.
322 - Fix: built-in "play_note()" function now returns 0 as result value if
323 -1 was passed for its fourth argument (note duration) and the respective
324 parent note is already gone.
325 - Implemented built-in script function "change_play_pos()".
326 - NKSP language: Added support for user declared const array variables.
327 - NKSP language: Raise parser warning if array variable is accessed with
328 an index that exceeds the array's size.
329 - NKSP language fix: Unknown characters were not handled correctly.
330 - NKSP language: Added support for "synchronized .. end synchronized"
331 code blocks.
332 - Implemented built-in script function "abort()" which allows to abort
333 another script handler by passing its callback ID.
334 - Fixed potential memory access bug and potential undefined behavior of
335 "init" event handlers.
336 - Print a time stamp along to each call of built-in function "message()".
337 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
338 to retrieve all code blocks filtered out by the preprocessor.
339 - Added built-in script function "fork()".
340 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
341 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
342 - Fixed potential crash when accessing dynamic built-in array variables.
343 - Added built-in script function "callback_status()".
344 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
345 - Added built-in constant $CALLBACK_STATUS_QUEUE.
346 - Added built-in constant $CALLBACK_STATUS_RUNNING.
347 - Removed max. value limitation of built-in functions "change_attack()",
348 "change_decay()" and "change_release()" to i.e. allow passing 2000000
349 for doubling the respective time.
350 - NKSP script editor syntax highlighting API: Fixed app termination due
351 to a lexer start condition stack underrun.
352 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
353 USE_CODE_IF_NOT() preprocessor statements.
354 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
355 can be set to disable all subsequent built-in "message()" function calls
356 on preprocessor level.
357 - Implemented built-in script function "change_sustain()".
358 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
359 to avoid the editor app to crash on ill-formed text input.
360 - Added built-in script function "change_pan_time()".
361 - Added built-in script function "change_pan_curve()".

369 * Instruments DB:
370 - Fixed memory access bug of general DB access code which lead to
371 undefined behavior.
372 - Cleanup of instruments DB file creation and opening code.
373 - The instrument DB path of linuxsampler's --create-instruments-db argument
374 is now optional, if it is missing, then a default location is used.
375 - Added support for scanning SFZ (.sfz) files.
376 - Added support for scanning Sound Font (.sf2) files.
377 - Fixed undefined DB transaction behavior.

417 in order to get rid of warnings from automake 1.14
418
419 * general changes:
420 - Refactoring: moved the independent code from
421 the Gigasampler format engine to base classes
422 - command line option '--profile' is currently disabled, since the
423 respective profiling code is currently broken
424 - Introduced support for optional environment variable
425 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
426 where the sampler shall look for instrument editor plugins
427 (patch by Luis Garrido, slightly modified).
428 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
429 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
430 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
431 note (in this implementation of the sampler its simply hard routed to
432 the 1st effect send of the sampler channel, no matter what the actual
433 effect type is)
434 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
435 note (in this implementation of the sampler its simply hard routed to
436 the 2nd effect send of the sampler channel, no matter what the actual
437 effect type is)

448 instruments for example are splitted over several files like
449 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
450 - Added new C++ API method Sampler::GetGlobalMaxVoices().
451 - Added new C++ API method Sampler::GetGlobalMaxStreams().
452 - Added new C++ API method Sampler::SetGlobalMaxVoices().
453 - Added new C++ API method Sampler::SetGlobalMaxStreams().
454 - Various "const" and "restrict" optimizations.
455 - all engines: add pan CC value to instrument pan parameter before
456 applying panning, instead of using two separate pan functions in
457 series (#182)
458 - added a lock guard class for exception safe mutex handling and
459 used it everywhere appropriate
460 - Immediately apply scale tuning changes to active voices.
461 - Exposed scale tuning to C++ API (along to the already existing standard
462 SysEx way).
463 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
464 and broken for ppc64. (Seq_cst loads and stores are actually not
465 used in LS, so the bug wasn't noticable.)
466 - lsatomic.h: added ARMv7 support
467 - Added support for multiple MIDI input ports per sampler channel (and
468 added various new C++ methods for this new feature / design change, old
469 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
470 as deprecated but are still there and should provide full behavior
471 backward compatibility).
472 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
473 unsafe and caused compilation error with clang 2.x).
474 - Bugfix: only process the latest MIDI program change event.
475 - Introducing the LSCP shell, which provides convenient control of the
476 sampler from the command line by providing LSCP aware features.
477 - VirtualMidiDevice: Added support for program change.
478 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
479 - VirtualMidiDevice: Added support for pitch bend.
480 - Aftertouch: extended API to explicitly handle channel pressure and
481 polyphonic key pressure events (so far polyphonic pressure was not
482 supported at all, and channel pressure was rerouted as CC128 but not
483 used so far).
484 - Added initial support for real-time instrument scripts. The script VM
485 code is shared by all sampler engine implemementations, however only the
486 gig file format currently provides support for storing instrument scripts
487 (as LinuxSampler extension to the original GigaStudio 4 format).

739 - added support for MIDI note on velocity filter
740 - CoreMIDI: fixed memory deallocation error
741 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

850 - Giga format scripts: Implemented built-in script function
851 "gig_set_dim_zone(event_id, dimension, zone)".
852 - Implemented built-in script int array variable %KEY_DOWN.
853 - Implemented built-in script function "abs()".
854 - Implemented built-in script function "random()".

861 - Built-in script functions "ignore_event()", "note_off()" and
862 "gig_set_dim_zone()" now also accept an array of event IDs as argument
863 (i.e. return value of new script function "by_marks()").
864 - Pass/preserve polyphonic variable data from respective "note" event
865 handler to "release" event handler.
866 - Fixed crash when using built-in script function "by_marks()".
867
868 * Bug fixes:
869 - Fixed crash which may occur when MIDI key + transpose is out of range
870 - minor valgrind fixes
871 - fixed crash which occurred when changing an already deployed sampler
872 channel to a different engine type
873 - fixed crash when deleting a sampler channel or changing engine
874 type while an instrument load was in progress
875 - bugfix: playing a note while changing the instrument could cause
876 a crash, or give "Handing back unknown region" error messages
877 - bugfix: calling SET VOICES (which Fantasia does on start and
878 refresh) could cause instruments to be unloaded
879 - Mac OS X: fixed name collision of enum in EffectControl and
880 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
881 - Mac OS X: fixed hanging threads
882 - Windows: disabled the previous thread fix on non-Mac systems, as
883 it caused hanging threads on Windows
884 - Fixed possible crashes due to corrupted MIDI/audio device list
885 after MIDI/audio device creation failure
886 - When creating MIDI instrument map entries with "PERSISTENT" type, the
887 instruments were uselessly precached with zero samples, however it still
888 took the full preloading time and on 1st program change the respective
889 instrument was completely reloaded again.
890 - fixed handling of rapid bank select and program change messages
891 sent to the same sampler channel (patch from the Open Octave
892 project, slightly adjusted)
893 - fixed crash when trying to create an effect instance with controls
894 which min and/or max values depend on the sample rate
895 - fixed bug #162
896 - bugfix: LADSPA_PATH was not evaluated correctly when containing
897 multiple paths (#165)
898 - thread safety fixes for the instrument loading thread
899 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
900 (#176)
901 - more thread safety fixes for the instrument loading thread
902 - sfz/sf2 engine: fixed crash when using small audio fragment size
903 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
904 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
905 introduced in previous fix)
906 - fixed crash when a channel received a program change while
907 playing a note in a key group
908 - fixed erroneous error message piping in VoiceBase.h
909 (labelled "Disk stream not available in time")
910 - Update effects on sample rate & period size changes (to avoid
911 crashes and noise on such transitions).
912 - ignore missing LADSPA paths without ignoring valid LADSPA paths
913 (fixes #208)
914 - Fixed bug in LSCP grammar definition which caused a statement like
915 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
916 practically irrelevant, however it caused problems with the new LSCP
917 shell's auto completion feature).
918 - Fixed MIDI program change messages being ignored if quickly executed
919 after each other (fixes #231).
920
921 Version 1.0.0 (31 July 2009)
922
923 * packaging changes:
924 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
925 causing e.g. the libgig test to fail when
926 "./configure --disable-jack-driver" was used
927 (patch by Alexis Ballier)
928 - fixed compilation with gcc 4.3
929 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
930 - fixed configure so it detects x86_64 (#107)
931 - fixes for building with newer MinGW versions
932 - fix for building with bison 2.4 (#111)
933 - fixed building with libgig installed in a non-standard directory
934 - minor fix in configure for mmsystem.h detection on MinGW
935 - Windows: look for editor plugins and Fantasia using base
936 directory of liblinuxsampler dll (look in the same directory and one
937 directory above)
938 - configure script fix: removed unconditional use of SSE
939 - fixed building with sqlite installed in a non-standard directory
940 - when cross-compiling, don't try to create instruments.db
941 - fix for new mingw-w64 version, which has usleep
942
943 * general changes:
944 - bugfix: on some POSIX systems instrument editor plugins refused to
945 load as we used a non-portable Linux specific struct field
946 (fixes bug #70, patch by Ronald Baljeu)
947 - fixed endless loop which occured when loading an instrument editor
948 plugin DLL on Windows systems failed
949 - fixed memory leaks that occurred when liblinuxsampler was unloaded
950 - optimized the SynchronizedConfig class so it doesn't wait
951 unnecessarily long after an update
952 - added support for notifying instrument editors on note-on / note-off
953 events (e.g. to highlight the pressed keys on the virtual keyboard
954 of gigedit)
955 - added support for triggering notes by instrument editors (see above)
956 - be verbose on DLL load errors (on Linux)
957 - fixed di-harmonic triangle LFO implementation (this LFO implementation
958 is only used by very few systems, most pick the int math
959 implementation, which is usually faster)
960 - fixes for audio drivers with varying buffer sizes
961 - experimental support for running LinuxSampler as a DSSI, LV2 and
962 VST plugin
963 - notification events for stream/voice count statistics are now sent
964 only when there are actual changes
965 - added memory ordering constraints to improve stability on
966 multi-core and multi-cpu systems
967 - maximum voices and disk streams can now be altered at runtime
968 - fixed CPU feature detection on x86_64 (maybe fixes #108)
969 - automatic stacktrace mechanism is now turned off by default and can
970 be switched on by command line option "--stacktrace" (the automatic
971 stacktrace mechanism seems to be broken on most systems at the moment)
972 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
973 a pointer to the launched InstrumentEditor object
974 - added optional 3rd party user data parameter for following
975 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
976 InstrumentEditor::Launch(),
977 InstrumentManager::LaunchInstrumentEditor()
978 - theoretical fix: made SynchronizedConfig follow C++0x memory
979 model more strictly
980 - fixes for using large audio device buffers
981 - Windows: add the installation directory to the DLL search path
982 when loading an editor plugin (solves problems with VST and
983 gigedit on systems with other GTK versions installed)
984 - updated linuxsampler man page
985
986 * audio driver:
987 - removed the nonsense audio channel constraint (which was hard coded to
988 max. 100 audio channels) for most audio drivers
989 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
990 opposed to the LSCP specs
991 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
992 reflected the wrong value
993 - fixed a memory management bug in ASIO driver
994 - Makefile fix: JACK_CFLAGS wasn't used
995 - JACK: use jack_client_open instead of the deprecated
996 jack_client_new
997 - added (experimental) CoreAudio driver
998 - applied old fixes to the ASIO driver that were included in the
999 previous binary release but accidentally never committed to CVS
1000 (fixes #117)
1001 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1002 win64)
1003 - VST: added support for sample rate and buffer size changes
1004 - VST: close editor (Fantasia) when the VST is removed
1005 - VST: avoid opening Fantasia more than once for each VST instance
1006 - VST: export main function as "main" on Linux too (fix for
1007 energyXT)
1008 - VST: changed number of output channels from one stereo to 16
1009 stereo
1010 - added channel routing, fxsends and midi maps to the settings
1011 stored in the plugin state
1012 - performance optimization of AudioChannel::MixTo() and
1013 AudioChannel::CopyTo() methods using GCC vector exensions
1014 (if available)
1015 - ASIO fixes: avoid initializing the device twice, avoid throwing
1016 exception when getting parameters from a disconnected device
1017
1018 * MIDI driver:
1019 - added JACK MIDI driver
1020 - dispatch bank select as ordinary CC as well, the user might seriously
1021 want to (mis)use it for some purpose ("fixed" in all current MIDI
1022 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1023 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1024 CoreMidi or AU
1025 - fixed mingw-w64 compilation error in MME driver
1026 - made program change handling in MIDI thread real-time safe by
1027 moving the logic to a non-RT thread
1028 - fixed minor memory leak in ALSA driver
1029
1030 * instruments database:
1031 - avoid time consuming samples scanning when adding instruments
1032 to the instruments database
1033 - added support for handling lost files in the instruments database
1034 - Implemented option for adding instruments in separate directories
1035 in the instruments database
1036 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1037 - work-around for missing fnmatch function on Windows to make
1038 instrument database compilable
1039 - added instrument database support on Windows
1040 works with both standalone mode and VST plugin.
1041 the instruments DB file is located in
1042 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1043 databases for each windows user
1044 if no DB is present it automatically creates the .linuxsampler subdir
1045 and then creates an empty DB
1046 - fixed recursive import, which was broken on Windows
1047
1048 * Gigasampler format engine:
1049 - fixed a memory leak that could happen when a channel was deleted
1050 while notes were playing
1051 - made it possible to load an instrument even if the audio thread
1052 isn't running
1053 - added partial support for the "Controller Triggered" MIDI rule,
1054 enough for piano gigs with pedal noise samples
1055 - minor fix: only mark FX sends as being modified if really the
1056 respective FX send MIDI controller was used
1057 - added support for GM global device volume SysEx message
1058 (can be selected at compile time to either apply globally to the
1059 whole sampler [default] or only to the sampler channels that are
1060 connected to the respective MIDI input port the SysEx message arrived
1061 on)
1062 - bugfix: notes triggered at position 0 in the audio buffer were
1063 sometimes wrongly killed in the same buffer, causing no sound to
1064 be played
1065 - added support for chromatic / drumkit mode Roland GS Sysex message
1066 which is usally used to switch a part between chromatic sounds and
1067 drumkit sounds (as opposed to their common default setting of MIDI
1068 part 10 being a drumkit part and all other ones chromatic parts), in
1069 LS however one can switch between the first 16 MIDI instrument maps
1070 defined for the sampler
1071 - made it possible to create multiple sample channels even if the
1072 audio thread isn't running
1073 - fixed crash when removing channel with active voices (#116)
1074 - bugfix: on sample reference changes (instrument editor), only
1075 un-cache the respective sample if it's really not used by any
1076 sampler engine anymore
1077 - re-cache samples in case they were changed by an instrument editor,
1078 e.g. when a sample was added while playing (#82)
1079 - fixed hanging notes which occured when note-off event had the exact
1080 same time stamp as the voice's note-on event and occured both in the
1081 same audio fragment cycle (fixes bug #112)
1082 - added support for the "fine tune" and "pitch bend range"
1083 instrument-level gig parameters
1084 - fixed minor artifacts in pitch bend handling
1085 - added support for GS Reset SysEx message
1086 - allow gig files to use unlimited downward pitch shifting
1087 - added a limit check for upward pitch shifting
1088 - bugfix: sometimes, when playing a note twice fast, the second
1089 note was silent
1090 - fixed crash happening when a pitch bend event arrived at the
1091 same time a new instrument was loading
1092
1093 * LSCP server:
1094 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1095 react on MIDI data arriving on certain sampler channels (so far only
1096 Note-On and Note-Off events are sent via this LSCP event)
1097 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1098 react on MIDI data arriving on certain MIDI input devices (so far only
1099 Note-On and Note-Off events are sent via this LSCP event)
1100 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1101 SET DB_INSTRUMENT FILE_PATH
1102 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1103 frontends to send MIDI messages to specific sampler channel
1104 - added two additional fields to GET FILE INSTRUMENT INFO command -
1105 KEY_BINDINGS and KEYSWITCH_BINDINGS
1106 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1107 was incorrect
1108 - Optimized the retrieval of the MIDI instrument mappings
1109 - added new LSCP command "SET VOICES" to globally alter the maximum
1110 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1111 be triggered respectively
1112 - added new LSCP command "SET STREAMS" to globally alter the maximum
1113 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1114 which will be triggered respectively
1115 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1116 a gigedit file dialog is opened)
1117 - close all connections when LSCPServer is deleted
1118 - hard close of all sockets on exit
1119 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1120 driver
1121
1122 * Bug fixes:
1123 - fixed a crash which occurs when removing a sampler channel waiting
1124 to start instrument loading after another channel
1125 - fixed a crash which occurs when removing a sampler channel with
1126 instrument loading in progress (bug #113)
1127 - fixed termination caused by uncaught exception when adding MIDI
1128 instrument with PERSISTENT load mode
1129 - fixed possible iterator invalidations when resetting the sampler
1130 - fixed memory leaks when issuing the following LSCP commands:
1131 GET AUDIO_OUTPUT_DRIVER INFO
1132 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1133 GET MIDI_INPUT_DRIVER INFO
1134 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1135 - fixed possible compilation error when sqlite is not present
1136 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1137 - fixed crash when changing the audio output device of a sampler
1138 channel with loaded instrument and start playing notes
1139 - fixed endless loop in Engine::SuspendAll() (bug #120)
1140 - fixed a low-level atomic load function that was broken on 64-bit
1141 PowerPC, which probably could cause crashes on that platform
1142 - fixed a memory management error which could cause a crash when a
1143 plugin was unloaded
1144 - bugfix: two private structs had the same name, which could cause
1145 problems if the linker chose the wrong constructor
1146 - fixed low-level ConditionServer usage bug that caused lockups on
1147 Windows
1148
1149
1150 Version 0.5.1 (6 December 2007)
1151
1152 * packaging changes:
1153 - added autoconf checks for pthread library
1154 - added autoconf check for pthread bug found on certain NPTL-enabled
1155 glibc versions (see Gentoo bug report #194076)
1156 - added autoconf checks for MS Windows
1157
1158 * general changes:
1159 - bugfix: the thread used by an editor plugin didn't die when the
1160 editor closed
1161 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1162 out all the space. operator--() did not apply size_mask after
1163 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1164 order to avoid problems with the _NonVolatileReader functions.
1165 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1166 GetWriteSpace(). Since this function is currently only used in
1167 the stream's qsort() compare function, it didn't trigger any
1168 bugs.
1169 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1170 24bit mode too. Faster method to read 24bit words on little
1171 endian machines (x86): replaced 3 byte reads + shifts with a 1
1172 unaligned 32bit read and shift
1173 - experimental support for MS Windows (MIDI input via MME, AUDIO
1174 output via ASIO)
1175 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1176 - support for monitoring the total number of active disk streams
1177 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1178 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1179
1180 * AUDIO driver:
1181 - added Windows ASIO low latency audio driver
1182
1183 * MIDI driver:
1184 - added MME Windows MIDI driver
1185
1186 * LSCP server:
1187 - added support for Windows style path / filenames, however with
1188 forward slash path separators instead of backslash
1189 (i.e. "C:/foo/bar.gig")
1190 - allow naughty liblscp to send non-string device parameters within
1191 apostrophes as well
1192 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1193 "LIST FILE INSTRUMENTS <file>" and
1194 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1195 about an arbitrary instrument file on the system where the sampler is
1196 running on
1197
1198 Version 0.5.0 (15 October 2007)
1199
1200 * packaging changes:
1201 - config.h is not going to be installed along with liblinuxsampler's
1202 API header files anymore
1203 - only the API relevant header (and source) files will be exported to
1204 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1205 - added completely new XCode project files for Mac OSX which is now
1206 capable to execute our autoconf environment, thus no need anymore
1207 to maintain the compile time configuration file (osx/version.h) for
1208 OSX manually (patch by Toshi Nagata)
1209 - fixed buggy boolean --enable-foo / --disable-foo configure script
1210 parameters
1211 - global.h now only covers global definitions that are needed for the
1212 C++ API header files, all implementation internal global definitions
1213 are now in global_private.h
1214 - atomic.h is not exposed to the C++ API anymore
1215 - no need to include config.h anymore for using LS's API header files
1216 - fixed warnings in API doc generation
1217
1218 * general changes:
1219 - replaced the old, confusing MIDI program change mechanism by a
1220 flexible MIDI instrument mapper which allows to map arbitrary
1221 (MIDI bank, MIDI program) pairs with arbitrary
1222 (engine type, instrument file, file index) triplets which will be
1223 loaded on the respective channel when such MIDI program change
1224 messages arrive, beside that, each entry allows to define a life-time
1225 strategy for the instrument, so the user can define whether the
1226 instrument should i.e. be permanently loaded (to be able to switch
1227 quickly among sounds) or i.e. loaded just on demand when the
1228 respective program change arrives (to safe RAM space), as well as a
1229 global volume factor for each entry, so the user can adjust the volume
1230 dynamic of his mapped instrument collection without having to modify
1231 the instrument files, also one can manage arbitrary amount of such
1232 MIDI instrument maps and assign each sampler channel individually
1233 a certain map, so that i.e. separation of normal instruments and
1234 drumkits is possible
1235 - new notification events for tracking changes to audio/MIDI devices,
1236 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1237 - sampler was limited to load max. 200 instruments in the background
1238 due to a constant size RingBuffer FIFO which is now replaced by a
1239 dynamic (unlimited) size std::list FIFO
1240 - added FX sends, these allow to route audio signals to arbitrary audio
1241 output channels for being processed by external effect processors
1242 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1243 controllers
1244 - global (sampler wide) volume can now be controlled at runtime
1245 - Implemented new, improved notification system
1246 - fixed compilation errors regarding OSX
1247 (patch by Toshi Nagata)
1248 - implemented instruments database
1249 - added support for escape sequences to the instruments database
1250 - added highly experimental support for on-the-fly instrument editing
1251 within the sampler's process (by using instrument editor plugins),
1252 you'll notice the new "Registered instrument editors:" message on
1253 startup, added a new LSCP command:
1254 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1255 to spawn a matching instrument editor for the instrument on the
1256 given sampler channel, the plugin path can be overridden at compile
1257 time with ./configure --enable-plugin-dir=/some/dir
1258 - added experimental code for synchronizing instrument editors hosted
1259 in the sampler's process to safely edit instruments while playing
1260 without a crash (hopefully) by either suspending single regions
1261 wherever possible or if unavoidable whole engine(s)
1262 - fixed several issues in fundamental "Thread" class: set scheduling
1263 policy and priority on thread level, set a minimum stack size for
1264 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1265 threads simply inherited properties of starting thread instead of
1266 setting their own policy and priority
1267 - minor fix in our automatic stack trace mechanism on crashes, the
1268 main process did not wait for the stack trace process to finish
1269 its output
1270 - fixed some minor memory leaks
1271 - reenabled assembly features support, at the moment only for
1272 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1273 - minor assembly fix in x86 features detection (don't use the PIC
1274 register, to avoid relocations in the text segment at runtime)
1275 - POSIX callback functions of Thread.h are hidden
1276
1277 * MIDI driver:
1278 - dispatch bank select (MSB and LSB) messages
1279
1280 * audio driver:
1281 - the ALSA audio output driver parameters now reflect the correct
1282 parameter value ranges for the respective selected sound card
1283 (patch by Till Wimmer, a bit fixed and extended)
1284
1285 * Gigasampler format engine:
1286 - if a filter is used and EG2 finishes before EG1, let the voice
1287 die when EG2 has finished (this fixes a problem with clicks and
1288 voice starvation for some gigs)
1289 - playback is no longer disabled during instrument loading
1290 - all notes playing on a channel that changes its instrument keep
1291 playing with the old instrument until they get a note off
1292 command
1293 - EG fix: a release value of zero could cause noises or crash
1294 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1295 - EG fine tuning: when attack is zero the EG starts at a level
1296 above max sustain level, which means that there is a decay phase
1297 even if sustain is 100%
1298 - more EG fixes: the level could sometimes go below zero and cause
1299 noises or crashes
1300 - minor fix of EGDecay (patch by Toshi Nagata)
1301 - fixed compiler error when --enable-override-filter-type was
1302 supplied to the configure script (fixes #46)
1303 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1304 instead of a fix value
1305 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1306 127 (solo mode) only kill voices if the respective mode really
1307 changed
1308
1309 * LSCP server:
1310 - fixed compile time error for old Bison versions
1311 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1312 - parser now supports extended ASCII character set
1313 (up to ASCII code 255, i.e. includes now umlauts and accents)
1314 - filename arguments in LSCP commands now allow to use escape
1315 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1316 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1317 code value like \xf2) (fixes bug #24)
1318 - the following LSCP commands now also support escape sequences for at
1319 least one of their text-based parameters (i.e. name, description):
1320 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1321 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1322 "SET DB_INSTRUMENT_DIRECTORY NAME",
1323 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1324 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1325 "FIND DB_INSTRUMENT_DIRECTORIES"
1326 - returns verbose syntax errors (line and column where syntax error
1327 occured, the unexpected character and the actually expected, possible
1328 character(s), the latter only if less than 5 possibilities)
1329 - made sure that LSCP syntax is not affected by gigedit locale
1330 settings
1331 - bugfix regarding strings parameter lists: all comma separated lists
1332 of strings were treated as being one string containing commas
1333 (fixes #57)
1334
1335 * Bug fixes:
1336 - fixed crash occurring on certain LSCP scripts (Bug 39)
1337 - another thread safety fix for lscp "load engine" and "set
1338 channel audio output device"
1339 - fixed a crash which occurs when reassigning the same engine
1340 on a sampler channel with connected MIDI device
1341 - fixed a crash which occurs when changing the number of ports of a MIDI
1342 device connected to a sampler channel to number less then or equal
1343 to the index of the port to which the sampler channel is connected.
1344 - The previous bindings were not been disconnected when altering
1345 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1346 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1347 - The active stream/voice count statistic was incorrect.
1348 - notification events were not been sent for some sampler
1349 channel changes
1350 - added default min and max values to restrict the number of allowed
1351 audio output channels and MIDI input ports
1352 - the connection to the PCM interface is now closed when destroying
1353 an audio output device
1354 - files with slash in their path or filename could not be loaded
1355
1356 * test cases:
1357 - updated and fixed (haven't been touched in a while)
1358
1359 Version 0.4.0 (24 November 2006)
1360
1361 * packaging changes:
1362 - changed deprecated copyright attribute to license; added ldconfig
1363 to post-(un)install steps; added devel package for liblinuxsampler;
1364 to linuxsampler.spec (RPM)
1365 - install necessary development header files for allowing 3rd party
1366 applications to link against liblinuxsampler
1367 - liblinuxsampler's API documentation can be generated with 'make docs'
1368 (Doxygen required)
1369 - added benchmark to automatically detect the best triangle LFO
1370 implementation (currently either an integer math solution or a
1371 di-harmonic approximation), automatic detection can be overriden
1372 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1373 configure script argument though (mandatory for cross-compilation)
1374 - do not automatically pick optimized gcc flags if the user already
1375 provided some on his own (as CXXFLAGS)
1376 - added compile time option to disable processing of All-Notes-Off MIDI
1377 messages
1378 - added compile time options to allow disabling the various audio and
1379 MIDI drivers
1380 - fixed automatic GCC CPU switch detection on PPC
1381 (patch by Ebrahim Mayat)
1382
1383 * Gigasampler format engine:
1384 - extensive synthesis optimization
1385 (reimplementation of EGs and LFO(s), removed synthesis parameter
1386 prerendering and the synthesis parameter matrix in general, splitting
1387 each audio fragment into subfragments now where each subfragment uses
1388 constant pitch and filter coefficients. The volume coefficient is
1389 linearly interpolated inside a subfragment, unless
1390 --disable-interpolate-volume is set.)
1391 - fine tuning of the EG modulation parameters
1392 - improved filter cutoff calculation by adding support for the
1393 following gig parameters: Cutoff freq (used when no cutoff
1394 controller is defined), Control invert, Minimum cutoff, Velocity
1395 curve and Velocity range. The keyboard tracking now scales
1396 cutoff frequency instead of resonance.
1397 - added support for gig parameter Resonance.
1398 - fixed bug in sysex handling (patch by Juan Linietsky)
1399 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1400 which can be overridden with --enable-global-attenuation
1401 - EG fixes: made the length of "attack hold" stage more
1402 accurate. Release stage can now start before attack stage
1403 ends. Cancel release didn't work when sustain was zero. Attack
1404 time now has a minimal value to prevent clicks.
1405 - fixed pitch changes larger than one octave
1406 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1407 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1408 all modes can be altered via standard GM messages, that is CC5 for
1409 altering portamento time, CC65 for enabling / disabling portamento
1410 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1411 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1412 parameter) and crossfade
1413 - added support for the "attenuation controller threshold" gig
1414 parameter
1415 - added smoothing of volume changes caused by control change
1416 messages
1417 - sample loop parameters are now taken from the DimensionRegion
1418 instead of the wave chunk
1419 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1420 not equal to a power of two
1421 - reimplementation of the filter algorithm. The new filter is more
1422 accurate and supports all gig filter types, including bandreject
1423 and lowpass turbo.
1424 - real support for 24 bit samples - samples are not truncated to
1425 16 bits anymore
1426 - support for aftertouch (channel pressure, not polyphonic
1427 aftertouch)
1428 - LFO1 behaviour fixed (dampening from max volume instead of
1429 amplifying from 0)
1430
1431 * LSCP server:
1432 - fixed application exit on broken pipe error (fixes bug #20)
1433 - fixed the notification messages delay due to lack of
1434 network activity (fixes bug #26)
1435 - fixed parser bug which occured on space(s) within device parameters
1436 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1437
1438 * audio driver:
1439 - added aRts audio output driver (by no means RT safe)
1440
1441 * MIDI driver:
1442 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1443 messages several times instead of once
1444 - API extension for MIDI drivers which already supply exact time stamps
1445 for events (i.e. for offline rendering based MIDI drivers)
1446 - added checks for bad MIDI data
1447
1448 * linuxsampler application:
1449 - show available sampler engine types on startup
1450
1451 * general changes:
1452 - support for muting sampler channels and solo mode of the same, two new
1453 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1454 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1455 introduced for this, the behavior is the same like on a mixer console
1456 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1457 --enable-process-muted-channels which can be used to enable the
1458 processing of muted channels.
1459 - support for sostenuto pedal
1460 - support for monitoring the total number of active voices
1461 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1462 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1463 - fixed some memory management errors
1464 - fixed some concurrency problems that could lead to crashes when
1465 LSCP commands were executed
1466 - fixed crash when instrument loading failed previously on the same
1467 sampler channel (fixes bug #36)
1468
1469 Version 0.3.3 (15 July 2005)
1470
1471 * packaging changes:
1472 - fixed compilation with gcc 4.0
1473
1474 * Gigasampler format engine:
1475 - LFO preprocessing was performed even though the respective LFO was
1476 disabled by the instrument patch (minor efficiency fix)
1477 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1478 for volume ramp downs in the same fragment (needed for current voice
1479 stealing implementation) then simply inform the user with a warning
1480 about possible click sounds and reduce the volume ramp down
1481 appropriately instead of cancelling the audio device connection
1482
1483 Version 0.3.2 (24 June 2005)
1484
1485 * packaging changes:
1486 - updated autotools build files to compile on OS X
1487 (conditional compilation of CoreMIDI and MidiShare drivers)
1488 - hand-crafted assembly optimization code can be disabled with
1489 './configure --disable-asm' (definitely not recommended)
1490 - fixed 'make dist' rule to include all necessary files
1491 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1492 (due to 'dist-bzip2' automake option)
1493
1494 * Gigasampler format engine:
1495 - support for the gig parameters for "release velocity response" curves
1496 - fine tuning of the EGADSR envelope
1497 - volume of release triggered samples now depends on note-on velocity,
1498 note length and gig parameter "release trigger decay" instead of
1499 note-off velocity.
1500 - revised voice stealing
1501 (fixes crash and endless loop caused by voice stealing)
1502 - don't reset scale tuning on instrument or audio output device change
1503 - handle key group conflicts right at the beginning of each fragment
1504 instead of when the respective voice is actually launched
1505 (fixes undefined behavior if stolen voices belonged to a key group -
1506 this case was followed by a "killed voice survived" error message)
1507 - fixed minor issue with null/silence samples
1508 (those stole voices even though they don't need a voice at all which
1509 resulted in "voice stealing didn't work out" messages)
1510 - don't reset volume, pan, pitch and MIDI controller values on
1511 instrument or audio output device change
1512
1513 * LSCP server:
1514 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1515 - fixed LSCP event "CHANNEL_INFO" notification
1516 (e.g. did not notify on volume changes or MIDI program change events)
1517
1518 * linuxsampler application:
1519 - added command line parameters --lscp-addr and --lscp-port to override
1520 default IP address and port of LSCP server
1521
1522 Version 0.3.1 (24 May 2005)
1523
1524 * initial release
