* Added test cases for NKSP core language aspects and core built-in
  functions.
* NKSP: Added method ScriptVM::setExitResultEnabled() which allows
  to explicitly enable the built-in exit() function to optionally
  accept one function argument; the value of the passed exit()
  function argument will then become available by calling
  VMExecContext::exitResult() after script execution.
* Bumped version (2.1.1.svn2).

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

190 - Added built-in script constant "$NI_CB_TYPE_NOTE".
191 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
192 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
193 - NKSP Language: Added support for user defined script functions.
194 - Implemented built-in script function "change_attack()".
195 - Implemented built-in script function "change_decay()".
196 - Implemented built-in script function "change_release()".
197 - Fixed all change_*() built-in script functions to apply their
198 synthesis parameter changes immediately in case the respective note
199 was triggered at the same time, instead of scheduling the parameter
200 change, especially because it would cause some parameter types's
201 changes either to be ramped (i.e. change_vol()) or other types even
202 to have not effect at all (i.e. change_attack()).
203 - Implemented built-in script function "sh_left()".
204 - Implemented built-in script function "sh_right()".
205 - Implemented built-in script function "min()".
206 - Implemented built-in script function "max()".
207 - NKSP Fix: "init" event handler was not always executed when a script
208 was loaded.
209 - NKSP built-in wait() script function: abort script execution if
210 a negative or zero wait time was passed as argument (since this is
211 a common indication of a bug either of the script or even of the
212 engine, which could lead to RT instability or even worse).
213 - ScriptVM: Implemented automatic suspension of RT safety
214 threatening scripts.
215 - Provide more user friendly error messages on syntax errors.
216 - Fixed NKSP parser warning "Not a statement" when assigning an
217 initializer list to an array variable.

220 - Implemented built-in script function "change_amp_lfo_depth()".
221 - Implemented built-in script function "change_amp_lfo_freq()".
222 - Implemented built-in script function "change_pitch_lfo_depth()".
223 - Implemented built-in script function "change_pitch_lfo_freq()".
224 - Implemented built-in script function "change_vol_time()".
225 - Implemented built-in script function "change_tune_time()".
226 - Implemented built-in script function "fade_in()".
227 - Implemented built-in script function "fade_out()".
228 - Fixed acceptance of wrong data type of parameters passed to built-in
229 script functions "change_vol()", "change_tune()", "change_pan()",
230 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
231 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
232 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
233 - Added built-in script function "get_event_par()" and implemented some
234 of its possible parameter selections.
235 - Added built-in script function "set_event_par()" and implemented some
236 of its possible parameter selections.
237 - Fixed a bunch of scheduler time related bugs.
238 - Fixed polyphonic variables not being reset to zero after usage.
239 - Built-in "ignore_event()" function: argument is now optional, like with
240 built-in function "ignore_controller()".
241 - Implemented built-in script function "change_velo()".
242 - Implemented built-in script function "change_note()".
243 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
244 intuitive behavior if used in combination with "change_vol_time()" or
245 "change_tune_time()" respectively: now tuning/volume changes are only
246 assigned (without delay) immediately to a new note if the respective
247 timing function has not been called before, otherwise the volume/tuning
248 changes are automatically faded (before, only the event's time stamp was
249 relevant).
250 - Implemented built-in script function "array_equal()".
251 - Implemented built-in script function "search()".
252 - Implemented built-in script function "sort()".
253 - NKSP Fix: Never suspend "init" event handlers.
254 - Implemented built-in script function "same_region()" (currently only
255 available for gig format engine).
256 - Added built-in script constant "$NKSP_LINEAR".
257 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
258 - Implemented built-in script function "change_vol_curve()".
259 - Implemented built-in script function "change_tune_curve()".
260 - built-in "play_note()" function now supports a sample playback start
261 offset with argument 3, where special value -1 means to use the regular
262 sample offset as defined by the instrument file.
263 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
264 - Built-in variable $EVENT_NOTE is now a read-only variable.
265 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
266 - built-in "play_note()" function now accepts -2 for its fourth argument
267 (note duration) which means the life time of the note shall be sticked
268 to the requested note number of argument 1.
269 - Fix: built-in "play_note()" function now returns 0 as result value if
270 -1 was passed for its fourth argument (note duration) and the respective
271 parent note is already gone.
272 - Implemented built-in script function "change_play_pos()".
273 - NKSP language: Added support for user declared const array variables.
274 - NKSP language: Raise parser warning if array variable is accessed with
275 an index that exceeds the array's size.
276 - NKSP language fix: Unknown characters were not handled correctly.
277 - NKSP language: Added support for "synchronized .. end synchronized"
278 code blocks.
279 - Implemented built-in script function "abort()" which allows to abort
280 another script handler by passing its callback ID.
281 - Fixed potential memory access bug and potential undefined behavior of
282 "init" event handlers.
283 - Print a time stamp along to each call of built-in function "message()".
284 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
285 to retrieve all code blocks filtered out by the preprocessor.
286 - Added built-in script function "fork()".
287 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
288 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
289 - Fixed potential crash when accessing dynamic built-in array variables.
290 - Added built-in script function "callback_status()".
291 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
292 - Added built-in constant $CALLBACK_STATUS_QUEUE.
293 - Added built-in constant $CALLBACK_STATUS_RUNNING.
294 - Removed max. value limitation of built-in functions "change_attack()",
295 "change_decay()" and "change_release()" to i.e. allow passing 2000000
296 for doubling the respective time.
297 - NKSP script editor syntax highlighting API: Fixed app termination due
298 to a lexer start condition stack underrun.
299 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
300 USE_CODE_IF_NOT() preprocessor statements.
301 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
302 can be set to disable all subsequent built-in "message()" function calls
303 on preprocessor level.
304 - Implemented built-in script function "change_sustain()".
305 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
306 to avoid the editor app to crash on ill-formed text input.
307 - Added built-in script function "change_pan_time()".
308 - Added built-in script function "change_pan_curve()".
309 - Added built-in script function "change_cutoff_attack()".

313 - Added built-in script function "change_cutoff_lfo_depth()".
314 - Added built-in script function "change_cutoff_lfo_freq()".
315
316 * Instruments DB:
317 - Fixed memory access bug of general DB access code which lead to
318 undefined behavior.
319 - Cleanup of instruments DB file creation and opening code.
320 - The instrument DB path of linuxsampler's --create-instruments-db argument
321 is now optional, if it is missing, then a default location is used.
322 - Added support for scanning SFZ (.sfz) files.
323 - Added support for scanning Sound Font (.sf2) files.
324 - Fixed undefined DB transaction behavior.
325

331 - Mac OS X: fixed building outside source directory
332 - made sure all source files for hostplugins are included when
333 doing "make dist"
334 - removed empty directories left from the cvs to svn migration
335 - fixed compilation with gcc 4.6.1
336 - another "make dist" fix, for the LV2 plugin

342 - Mac OS X: Makefile fix for the install-strip target
343 - fixed compilation with gcc 4.7
344 - fixed configure script error with old autoconf versions
345 - lsatomic.h: use gcc provided atomic functions if building with
346 gcc 4.7 and C++11
347 - modernized configure script
348 - fixed linkage error when building with
349 LDFLAGS="-Wl,--no-undefined" (#190)
350 - fixed compilation with Clang 3.2
351 - removed usage of deprecated Automake variable INCLUDES
352 - fixed building with C++11

355 makefiles
356 - fix for building with bison 3.0 (#202)
357 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
358 on the process's main thread
359 - fixed build error on newer MinGW
360 - support building with older jack versions
361 - support building with spaces in vst sdk path
362 - enabled automake 'subdir-objects' option and moved external
363 source references (vst, au, asio) from makefiles to cpp files,
364 in order to get rid of warnings from automake 1.14
365
366 * general changes:
367 - Refactoring: moved the independent code from
368 the Gigasampler format engine to base classes
369 - command line option '--profile' is currently disabled, since the
370 respective profiling code is currently broken
371 - Introduced support for optional environment variable
372 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
373 where the sampler shall look for instrument editor plugins
374 (patch by Luis Garrido, slightly modified).
375 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
376 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
377 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
378 note (in this implementation of the sampler its simply hard routed to
379 the 1st effect send of the sampler channel, no matter what the actual
380 effect type is)
381 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
382 note (in this implementation of the sampler its simply hard routed to
383 the 2nd effect send of the sampler channel, no matter what the actual
384 effect type is)
385 - implemented support for internal LADSPA effects
386 - raised limit of program change queue from 100 to 512
387 (as suggested by Alex Stone)
388 - implemented sine LFO, pulse LFO and saw LFO
389 - experimental support for per voice equalization
390 - added command line option --exec-after-init
391 - Introduced new C++ API method:
392 EngineChannel::InstrumentFileName(int index)
393 allowing to retrieve the whole list of files used for the loaded
394 instrument on an engine channel (a.k.a. part). Some GigaStudio
395 instruments for example are splitted over several files like
396 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
397 - Added new C++ API method Sampler::GetGlobalMaxVoices().
398 - Added new C++ API method Sampler::GetGlobalMaxStreams().
399 - Added new C++ API method Sampler::SetGlobalMaxVoices().
400 - Added new C++ API method Sampler::SetGlobalMaxStreams().
401 - Various "const" and "restrict" optimizations.
402 - all engines: add pan CC value to instrument pan parameter before
403 applying panning, instead of using two separate pan functions in
404 series (#182)
405 - added a lock guard class for exception safe mutex handling and
406 used it everywhere appropriate
407 - Immediately apply scale tuning changes to active voices.
408 - Exposed scale tuning to C++ API (along to the already existing standard
409 SysEx way).
410 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
411 and broken for ppc64. (Seq_cst loads and stores are actually not
412 used in LS, so the bug wasn't noticable.)
413 - lsatomic.h: added ARMv7 support
414 - Added support for multiple MIDI input ports per sampler channel (and
415 added various new C++ methods for this new feature / design change, old
416 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
417 as deprecated but are still there and should provide full behavior
418 backward compatibility).
419 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
420 unsafe and caused compilation error with clang 2.x).
421 - Bugfix: only process the latest MIDI program change event.
422 - Introducing the LSCP shell, which provides convenient control of the
423 sampler from the command line by providing LSCP aware features.
424 - VirtualMidiDevice: Added support for program change.
425 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
426 - VirtualMidiDevice: Added support for pitch bend.
427 - Aftertouch: extended API to explicitly handle channel pressure and
428 polyphonic key pressure events (so far polyphonic pressure was not
429 supported at all, and channel pressure was rerouted as CC128 but not
430 used so far).
431 - Added initial support for real-time instrument scripts. The script VM
432 code is shared by all sampler engine implemementations, however only the
433 gig file format currently provides support for storing instrument scripts
434 (as LinuxSampler extension to the original GigaStudio 4 format).
435
436 * Gigasampler format engine:
437 - implemented the "round robin keyboard" dimension
438 - fixed round robin and random dimensions for cases when number of
439 dimension zones is not a power of two
440 - made round robin use a counter for each region instead of each
441 key
442 - bugfix: pitch LFO controller "internal+aftertouch" was broken
443 - bugfix: filter keyboard tracking was broken
444 - filter performance fix (an unnecessary copy was made of the
445 filter parameters in each sub fragment)
446 - handle special case when pan parameter in gig file has max or
447 min value
448 - Exclusive Groups: don't ever stop voices of the same note,
449 doesn't sound naturally with a drumkit
450 - fixed EG1 modulation when attack or release is zero
451 - Fixed support for 'aftertouch' attenuation controller.
452 - Fixed crash that happened with velocity split sounds under certain
453 conditions (see also previous commit on libgig).
454 - fixed behaviour of filter LFO
455
456 * SFZ format engine:
457 - Initial implementation (not usable yet)
458 - added support for v2 multiple stage envelope generators
459 - added a fine-tuned v1 envelope generator instead of using the
460 one from the gig engine
461 - fixed memory leak and memory handling errors

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