* FX Sends: Provide more useful error messages on routing problems
  (see bug #169).
* LSCP reference doc: Be more clear describing the two distinct
  approaches of using external vs. internal effects (see bug #169).
* Bumped version (2.1.0.svn8).

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

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

197 - Implemented built-in script function "change_amp_lfo_depth()".
198 - Implemented built-in script function "change_amp_lfo_freq()".
199 - Implemented built-in script function "change_pitch_lfo_depth()".
200 - Implemented built-in script function "change_pitch_lfo_freq()".
201 - Implemented built-in script function "change_vol_time()".
202 - Implemented built-in script function "change_tune_time()".
203 - Implemented built-in script function "fade_in()".
204 - Implemented built-in script function "fade_out()".
205 - Fixed acceptance of wrong data type of parameters passed to built-in
206 script functions "change_vol()", "change_tune()", "change_pan()",
207 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
208 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
209 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
210 - Added built-in script function "get_event_par()" and implemented some
211 of its possible parameter selections.
212 - Added built-in script function "set_event_par()" and implemented some
213 of its possible parameter selections.
214 - Fixed a bunch of scheduler time related bugs.
215 - Fixed polyphonic variables not being reset to zero after usage.
216 - Built-in "ignore_event()" function: argument is now optional, like with
217 built-in function "ignore_controller()".
218 - Implemented built-in script function "change_velo()".
219 - Implemented built-in script function "change_note()".
220 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
221 intuitive behavior if used in combination with "change_vol_time()" or
222 "change_tune_time()" respectively: now tuning/volume changes are only
223 assigned (without delay) immediately to a new note if the respective
224 timing function has not been called before, otherwise the volume/tuning
225 changes are automatically faded (before, only the event's time stamp was
226 relevant).
227 - Implemented built-in script function "array_equal()".
228 - Implemented built-in script function "search()".
229 - Implemented built-in script function "sort()".
230 - NKSP Fix: Never suspend "init" event handlers.
231 - Implemented built-in script function "same_region()" (currently only
232 available for gig format engine).
233 - Added built-in script constant "$NKSP_LINEAR".
234 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
235 - Implemented built-in script function "change_vol_curve()".
236 - Implemented built-in script function "change_tune_curve()".
237 - built-in "play_note()" function now supports a sample playback start
238 offset with argument 3, where special value -1 means to use the regular
239 sample offset as defined by the instrument file.
240 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
241 - Built-in variable $EVENT_NOTE is now a read-only variable.
242 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
243 - built-in "play_note()" function now accepts -2 for its fourth argument
244 (note duration) which means the life time of the note shall be sticked
245 to the requested note number of argument 1.
246 - Fix: built-in "play_note()" function now returns 0 as result value if
247 -1 was passed for its fourth argument (note duration) and the respective
248 parent note is already gone.
249 - Implemented built-in script function "change_play_pos()".
250 - NKSP language: Added support for user declared const array variables.
251 - NKSP language: Raise parser warning if array variable is accessed with
252 an index that exceeds the array's size.
253 - NKSP language fix: Unknown characters were not handled correctly.
254 - NKSP language: Added support for "synchronized .. end synchronized"
255 code blocks.
256 - Implemented built-in script function "abort()" which allows to abort
257 another script handler by passing its callback ID.
258 - Fixed potential memory access bug and potential undefined behavior of
259 "init" event handlers.
260 - Print a time stamp along to each call of built-in function "message()".
261 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
262 to retrieve all code blocks filtered out by the preprocessor.
263 - Added built-in script function "fork()".
264 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
265 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
266 - Fixed potential crash when accessing dynamic built-in array variables.
267 - Added built-in script function "callback_status()".
268 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
269 - Added built-in constant $CALLBACK_STATUS_QUEUE.
270 - Added built-in constant $CALLBACK_STATUS_RUNNING.
271 - Removed max. value limitation of built-in functions "change_attack()",
272 "change_decay()" and "change_release()" to i.e. allow passing 2000000
273 for doubling the respective time.
274 - NKSP script editor syntax highlighting API: Fixed app termination due
275 to a lexer start condition stack underrun.
276 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
277 USE_CODE_IF_NOT() preprocessor statements.
278 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
279 can be set to disable all subsequent built-in "message()" function calls
280 on preprocessor level.
281 - Implemented built-in script function "change_sustain()".
282 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
283 to avoid the editor app to crash on ill-formed text input.
284 - Added built-in script function "change_pan_time()".
285 - Added built-in script function "change_pan_curve()".
286 - Added built-in script function "change_cutoff_attack()".
287 - Added built-in script function "change_cutoff_decay()".
288 - Added built-in script function "change_cutoff_sustain()".
289 - Added built-in script function "change_cutoff_release()".
290 - Added built-in script function "change_cutoff_lfo_depth()".
291 - Added built-in script function "change_cutoff_lfo_freq()".
292
293 * Instruments DB:
294 - Fixed memory access bug of general DB access code which lead to
295 undefined behavior.
296 - Cleanup of instruments DB file creation and opening code.
297 - The instrument DB path of linuxsampler's --create-instruments-db argument
298 is now optional, if it is missing, then a default location is used.
299 - Added support for scanning SFZ (.sfz) files.
300 - Added support for scanning Sound Font (.sf2) files.
301 - Fixed undefined DB transaction behavior.
302

306 - fixed building with newer MinGW-w64
307 - Mac OS X: support the new dir for Core Audio SDK
308 - Mac OS X: fixed building outside source directory
309 - made sure all source files for hostplugins are included when
310 doing "make dist"
311 - removed empty directories left from the cvs to svn migration
312 - fixed compilation with gcc 4.6.1
313 - another "make dist" fix, for the LV2 plugin
314 - made --enable-pthread-testcancel default on Mac OS X

319 - Mac OS X: Makefile fix for the install-strip target
320 - fixed compilation with gcc 4.7
321 - fixed configure script error with old autoconf versions
322 - lsatomic.h: use gcc provided atomic functions if building with

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

839 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
840 practically irrelevant, however it caused problems with the new LSCP
841 shell's auto completion feature).

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