* sfz opcode 'sample': Added support for built-in sample '*silence'
  (fixes bug #310, patch by Jacek Roszkowski).
* sfz opcode 'sample': Show warning message for unknown or unsupported
  built-in sample types.
* Bumped version (2.1.0.svn7).

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

167 - Implemented built-in script function "change_attack()".
168 - Implemented built-in script function "change_decay()".
169 - Implemented built-in script function "change_release()".
170 - Fixed all change_*() built-in script functions to apply their
171 synthesis parameter changes immediately in case the respective note
172 was triggered at the same time, instead of scheduling the parameter
173 change, especially because it would cause some parameter types's
174 changes either to be ramped (i.e. change_vol()) or other types even
175 to have not effect at all (i.e. change_attack()).
176 - Implemented built-in script function "sh_left()".
177 - Implemented built-in script function "sh_right()".
178 - Implemented built-in script function "min()".
179 - Implemented built-in script function "max()".
180 - NKSP Fix: "init" event handler was not always executed when a script
181 was loaded.
182 - NKSP built-in wait() script function: abort script execution if
183 a negative or zero wait time was passed as argument (since this is
184 a common indication of a bug either of the script or even of the
185 engine, which could lead to RT instability or even worse).
186 - ScriptVM: Implemented automatic suspension of RT safety
187 threatening scripts.
188 - Provide more user friendly error messages on syntax errors.
189 - Fixed NKSP parser warning "Not a statement" when assigning an
190 initializer list to an array variable.

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

286 - Added built-in script function "change_cutoff_lfo_depth()".
287 - Added built-in script function "change_cutoff_lfo_freq()".
288
289 * Instruments DB:
290 - Fixed memory access bug of general DB access code which lead to
291 undefined behavior.
292 - Cleanup of instruments DB file creation and opening code.
293 - The instrument DB path of linuxsampler's --create-instruments-db argument
294 is now optional, if it is missing, then a default location is used.
295 - Added support for scanning SFZ (.sfz) files.
296 - Added support for scanning Sound Font (.sf2) files.
297 - Fixed undefined DB transaction behavior.
298

304 - Mac OS X: fixed building outside source directory
305 - made sure all source files for hostplugins are included when
306 doing "make dist"

315 - Mac OS X: Makefile fix for the install-strip target
316 - fixed compilation with gcc 4.7
317 - fixed configure script error with old autoconf versions

328 makefiles
329 - fix for building with bison 3.0 (#202)
330 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
331 on the process's main thread
332 - fixed build error on newer MinGW
333 - support building with older jack versions
334 - support building with spaces in vst sdk path
335 - enabled automake 'subdir-objects' option and moved external
336 source references (vst, au, asio) from makefiles to cpp files,
337 in order to get rid of warnings from automake 1.14
338
339 * general changes:
340 - Refactoring: moved the independent code from
341 the Gigasampler format engine to base classes
342 - command line option '--profile' is currently disabled, since the
343 respective profiling code is currently broken
344 - Introduced support for optional environment variable
345 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
346 where the sampler shall look for instrument editor plugins
347 (patch by Luis Garrido, slightly modified).
348 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
349 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
350 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
351 note (in this implementation of the sampler its simply hard routed to
352 the 1st effect send of the sampler channel, no matter what the actual
353 effect type is)
354 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
355 note (in this implementation of the sampler its simply hard routed to
356 the 2nd effect send of the sampler channel, no matter what the actual
357 effect type is)
358 - implemented support for internal LADSPA effects
359 - raised limit of program change queue from 100 to 512
360 (as suggested by Alex Stone)
361 - implemented sine LFO, pulse LFO and saw LFO
362 - experimental support for per voice equalization
363 - added command line option --exec-after-init
364 - Introduced new C++ API method:
365 EngineChannel::InstrumentFileName(int index)
366 allowing to retrieve the whole list of files used for the loaded
367 instrument on an engine channel (a.k.a. part). Some GigaStudio
368 instruments for example are splitted over several files like
369 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
370 - Added new C++ API method Sampler::GetGlobalMaxVoices().
371 - Added new C++ API method Sampler::GetGlobalMaxStreams().
372 - Added new C++ API method Sampler::SetGlobalMaxVoices().
373 - Added new C++ API method Sampler::SetGlobalMaxStreams().
374 - Various "const" and "restrict" optimizations.
375 - all engines: add pan CC value to instrument pan parameter before
376 applying panning, instead of using two separate pan functions in
377 series (#182)
378 - added a lock guard class for exception safe mutex handling and
379 used it everywhere appropriate
380 - Immediately apply scale tuning changes to active voices.
381 - Exposed scale tuning to C++ API (along to the already existing standard
382 SysEx way).
383 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
384 and broken for ppc64. (Seq_cst loads and stores are actually not
385 used in LS, so the bug wasn't noticable.)
386 - lsatomic.h: added ARMv7 support
387 - Added support for multiple MIDI input ports per sampler channel (and
388 added various new C++ methods for this new feature / design change, old
389 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
390 as deprecated but are still there and should provide full behavior
391 backward compatibility).
392 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
393 unsafe and caused compilation error with clang 2.x).
394 - Bugfix: only process the latest MIDI program change event.
395 - Introducing the LSCP shell, which provides convenient control of the
396 sampler from the command line by providing LSCP aware features.
397 - VirtualMidiDevice: Added support for program change.
398 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
399 - VirtualMidiDevice: Added support for pitch bend.
400 - Aftertouch: extended API to explicitly handle channel pressure and
401 polyphonic key pressure events (so far polyphonic pressure was not
402 supported at all, and channel pressure was rerouted as CC128 but not
403 used so far).
404 - Added initial support for real-time instrument scripts. The script VM
405 code is shared by all sampler engine implemementations, however only the
406 gig file format currently provides support for storing instrument scripts
407 (as LinuxSampler extension to the original GigaStudio 4 format).
408
409 * Gigasampler format engine:
410 - implemented the "round robin keyboard" dimension
411 - fixed round robin and random dimensions for cases when number of
412 dimension zones is not a power of two
413 - made round robin use a counter for each region instead of each
414 key
415 - bugfix: pitch LFO controller "internal+aftertouch" was broken
416 - bugfix: filter keyboard tracking was broken
417 - filter performance fix (an unnecessary copy was made of the
418 filter parameters in each sub fragment)
419 - handle special case when pan parameter in gig file has max or
420 min value
421 - Exclusive Groups: don't ever stop voices of the same note,
422 doesn't sound naturally with a drumkit
423 - fixed EG1 modulation when attack or release is zero
424 - Fixed support for 'aftertouch' attenuation controller.
425 - Fixed crash that happened with velocity split sounds under certain
426 conditions (see also previous commit on libgig).
427 - fixed behaviour of filter LFO
428
429 * SFZ format engine:
430 - Initial implementation (not usable yet)
431 - added support for v2 multiple stage envelope generators
432 - added a fine-tuned v1 envelope generator instead of using the
433 one from the gig engine
434 - fixed memory leak and memory handling errors
435 - added support for trigger=first, trigger=legato and sw_previous
436 - allow non-numerical key values ("C#4" for example)
437 - "key" opcode now sets pitch_keycenter too
438 - fixed error when unloading instrument with same sample used by
439 multiple regions
440 - added some opcode aliases, like loopmode for loop_mode, to be
441 more compatible
442 - added support for trigger=release and rt_decay
443 - added support for off_mode=normal
444 - added support for random, seq_position, seq_length and volume
445 - added v1 LFO opcodes to parser (no support in engine yet)
446 - added support for amp_veltrack and amp_velcurve_N
447 - fine-tuned the default velocity curve
448 - added support for transpose
449 - fixed crash when using sw_down/up
450 - improved logic for sw_lokey/hikey/up/down/last
451 - added more v1 aliases to parser
452 - reduced memory usage for sfz data
453 - RT-safeness: avoid malloc in audio thread
454 - fixed a bug that could cause voice stealing to fail
455 - optimized sample lookup
456 - improved support for exclusive groups (group, off_by and
457 off_mode)
458 - added support for controller triggered regions (on_locc/on_hicc)
459 - added support for loop_mode=one_shot

835 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
836 practically irrelevant, however it caused problems with the new LSCP
837 shell's auto completion feature).
838 - Fixed MIDI program change messages being ignored if quickly executed

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