* NKSP: Introducing 64 bit support for NKSP integer scripts
  variables (declare $foo).
* Require C++11 compiler support.
* Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
  for checking in configure for C++11 support (as mandatory
  requirement) and automatically adds compiler argument if required
  (e.g. -std=C++11).
* Bumped version (2.1.1.svn3).

1 Version SVN trunk (?)
2
3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++11 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++11 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++11).
10
11 * Real-time instrument scripts:
12 - Added method ScriptVM::setExitResultEnabled() which allows to
13 explicitly enable the built-in exit() function to optionally accept
14 one function argument; the value of the passed exit() function
15 argument will then become available by calling
16 VMExecContext::exitResult() after script execution.
17 - 64 bit support for NKSP integer scripts variables (declare $foo).
18
19 * test cases:
20 - Fixed compiler errors in test cases.
21 - Updated README for how to compile & run test cases.
22 - Updated test case
23 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
24 expected behaviour of the Mutex class implementation (recursive
25 mutex type).
26 - Added test cases for NKSP core language aspects and core built-in
27 functions.
28 - Fixed thread tests segfaulting on Linux.
29
30 Version 2.1.1 (27 Jul 2019)
31
32 * Real-time instrument scripts:
33 - Fixed behavior of built-in NKSP functions change_sustain(),
34 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
35 and change_cutoff_release().
36
37 * general changes:
38 - Only play release trigger samples on sustain pedal up if this behaviour
39 was explicitly requested by the instrument (otherwise only on note-off).
40 - Fixed compiler warnings.
41 - Fixed compilation error when cross-compiling to Mac.
42 - FX Sends: Provide more useful error messages on routing problems
43 (see bug #169).
44 - LSCP doc: Be more clear describing the two distinct approaches
45 of using external vs. internal effects (see bug #169).
46 - "optional" class: Fixed comparison operators.
47
48 * Gigasampler/GigaStudio format engine:
49 - Format extension: If requested by instrument then don't play release
50 trigger sample on note-off events.
51
52 * SFZ format engine:
53 - Fixed memory leak when releasing samples
54 (fixes bug #307, patch by Jacek Roszkowski)
55 - Fixed potential crash when a sample is shared by more than one region
56 (fixes bug #308, patch by Jacek Roszkowski).
57 - Opcode 'sample': Added support for built-in sample '*silence'
58 (fixes bug #310, patch by Jacek Roszkowski).
59
60 Version 2.1.0 (25 Nov 2017)
61
62 * SFZ format engine:
63 - added support for <global>, <master> and #define (patch by Alby M)
64 - Removed code duplication in SFZ file loading code.
65 - Added support for sfz extension opcode 'script' which may be used to
66 load real-time instrument script file (NKSP script language).
67 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
68 - Fixed unintended volume fade-in of voices under certain conditions.
69 - sfz parser: allow missing space between header and opcode
70
71 * Gigasampler/GigaStudio format engine:
72 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
73 cutoff settings.
74 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
75 all if an up-pitch of more than 40 semi tones was requested (I don't
76 think there is any stock gig sound that requires this behavior to
77 resemble its original sound).
78 - Added support for controlling whether the individual EGADSR stages may
79 be aborted (as LinuxSampler extension to the original GigaStudio 4
80 format).
81
82 * general changes:
83 - fixed printf type errors (mostly in debug messages)
84 - use unique_ptr instead of auto_ptr when building with C++11
85 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
86 allowing to sort data efficiently in real-time safe manner.
87 - RTList class: added methods for moving/inserting elements to arbitrary
88 position within a list.
89 - RTList class: added method fromPtr() for creating an Iterator object from
90 a raw element pointer.
91 - Attempt to partly fix resetting engine channels vs. resetting engine, an
92 overall cleanup of the Reset*(), ConnectAudioDevice(),
93 DisconnectAudioDevice() API methods would still be desirable though,
94 because the current situation is still inconsistent and error prone.
95 - Active voices are now internally grouped to "Note" objects, instead of
96 being directly assigned to a keyboard key. This allows more fine graded
97 processing of voices, which is i.e. required for certain instrument
98 script features.
99 - Fix: Release trigger voices were not spawned on sustain pedal up
100 (CC #64) events.
101 - Fix: Release trigger voices can now also distinguish correctly between
102 note-off and sustain pedal up events.
103 - All engines: Increased ramp speed of volume smoother and pan smoother
104 (while slow rate of crossfade smoother is preserved) to allow quick
105 volume and pan changes by instrument scripts for instance.
106 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
107 properly and thus were ignored for certain uses.
108 - Added new C++ API method
109 VirtualMidiDevice::SendChannelPressureToSampler().
110 - windows, 32-bit: fixed potential crashes by making sure the stack in
111 sub threads is 16-byte aligned
112 - fixed numerous compiler warnings
113 - Fixed invalid (note-on) event ID being assigned to new Note objects.
114 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
115 fixes potential undefined behavior.
116 - Fixed Note object leak when triggering notes on keys which did not
117 have a valid sample mapped (fixes bug #252).
118 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
119 - linuxsampler binary fix: option --create-instruments-db ignored
120 subsequent optional argument due to glibc's implementation oddity
121 which expects a "=" sign, but no space between them.
122
123 * packaging changes:
124 - removed unnecessary dependency to libuuid
125 (originated by libgig's usage of it)
126 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
127 auto detect whether it (sh/c)ould output its messages in color.
128 - Debian: Fixed packaging error about invalid "Source-Version"
129 substitution variable.
130 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
131 - Debian: Added build dependency to libsqlite3-dev for building
132 linuxsampler with instruments DB support.
133
134 * Real-time instrument scripts:
135 - Implemented scheduler for delayed MIDI events and for suspended scripts.
136 - Built-in script function "wait()": implemented support for function's
137 "duration-us" argument, thus scripts using this function are now
138 correctly resumed after the requested amount of microseconds.
139 - Built-in script function "play_note()": implemented support for
140 function's "duration-us" argument, thus notes triggered with this
141 argument are now correctly released after the requested amount of
142 microseconds.
143 - Fix: script events were not cleared when engine channel was reset,
144 potentially causing undefined behavior.
145 - Fixed crash which happened when trying to reference an undeclared
146 variable.
147 - Built-in script function "play_note()": Added support for passing
148 special value -1 for "duration-us" argument, which will cause the
149 triggered note to be released once the original note was released.
150 - Instrument script classes now exported with the liblinuxsampler C++ API.
151 - Added new API method ScriptVM::syntaxHighlighting() which provides
152 a convenient syntax highlighting backend for external instrument
153 script editor applications.
154 - Added new C++ API class "ScriptVMFactory".
155 - Extended parser issues to provide not only first line and first
156 column, but also last line and last column of issue (thus marking
157 the precise span of the issue within the source code).
158 - Reload script automatically after being modified by an instrument
159 editor.
160 - NKSP language grammar correction: allow empty event handler bodies
161 like "on note end on".
162 - Implemented built-in script function "change_vol()".
163 - Implemented built-in script function "change_tune()".
164 - Implemented built-in script function "change_pan()".
165 - Implemented built-in script function "change_cutoff()".
166 - Implemented built-in script function "change_reso()".
167 - Implemented built-in script function "event_status()".
168 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
169 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
170 "event_status()" function.
171 - NKSP language: Added support for bitwise operators ".or.", ".and."
172 and ".not.".
173 - NKSP language scanner: Fixed IDs matching to require at least one
174 character (i.e. when matching function names or variable names).
175 - NKSP language scanner: disabled unusued rules.
176 - Fixed behavior of play_note() and note_off() functions which must
177 be distinguished engine internally from "real" MIDI note on/off
178 events in order to avoid misbehaviors like hanging notes.
179 - Implemented built-in script variable "$KSP_TIMER".
180 - Implemented built-in script variable "$NKSP_REAL_TIMER".
181 - Implemented built-in script variable "$NKSP_PERF_TIMER".
182 - Implemented built-in script variable "$ENGINE_UPTIME".
183 - Implemented built-in script function "inc()".
184 - Implemented built-in script function "dec()".
185 - NKSP language fix: division expressions were evaluated too often.
186 - NKSP language fix: string concatenation operator was right
187 associative instead of left (to right).
188 - NKSP language correction: allow empty statements in entire language
189 (i.e. "if end if").
190 - Implemented built-in script function "stop_wait()".
191 - Implemented built-in script variable "$NI_CALLBACK_ID".
192 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
193 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
194 - Added support for read-only built-in variables (respectively
195 handled by the script parser).
196 - Added built-in script constant "$NI_CB_TYPE_INIT".
197 - Added built-in script constant "$NI_CB_TYPE_NOTE".
198 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
199 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
200 - NKSP Language: Added support for user defined script functions.
201 - Implemented built-in script function "change_attack()".
202 - Implemented built-in script function "change_decay()".
203 - Implemented built-in script function "change_release()".
204 - Fixed all change_*() built-in script functions to apply their
205 synthesis parameter changes immediately in case the respective note
206 was triggered at the same time, instead of scheduling the parameter
207 change, especially because it would cause some parameter types's
208 changes either to be ramped (i.e. change_vol()) or other types even
209 to have not effect at all (i.e. change_attack()).
210 - Implemented built-in script function "sh_left()".
211 - Implemented built-in script function "sh_right()".
212 - Implemented built-in script function "min()".
213 - Implemented built-in script function "max()".
214 - NKSP Fix: "init" event handler was not always executed when a script
215 was loaded.
216 - NKSP built-in wait() script function: abort script execution if
217 a negative or zero wait time was passed as argument (since this is
218 a common indication of a bug either of the script or even of the
219 engine, which could lead to RT instability or even worse).
220 - ScriptVM: Implemented automatic suspension of RT safety
221 threatening scripts.
222 - Provide more user friendly error messages on syntax errors.
223 - Fixed NKSP parser warning "Not a statement" when assigning an
224 initializer list to an array variable.

227 - Implemented built-in script function "change_amp_lfo_depth()".
228 - Implemented built-in script function "change_amp_lfo_freq()".
229 - Implemented built-in script function "change_pitch_lfo_depth()".
230 - Implemented built-in script function "change_pitch_lfo_freq()".
231 - Implemented built-in script function "change_vol_time()".
232 - Implemented built-in script function "change_tune_time()".
233 - Implemented built-in script function "fade_in()".
234 - Implemented built-in script function "fade_out()".
235 - Fixed acceptance of wrong data type of parameters passed to built-in
236 script functions "change_vol()", "change_tune()", "change_pan()",
237 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
238 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
239 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
240 - Added built-in script function "get_event_par()" and implemented some
241 of its possible parameter selections.
242 - Added built-in script function "set_event_par()" and implemented some
243 of its possible parameter selections.
244 - Fixed a bunch of scheduler time related bugs.
245 - Fixed polyphonic variables not being reset to zero after usage.
246 - Built-in "ignore_event()" function: argument is now optional, like with
247 built-in function "ignore_controller()".
248 - Implemented built-in script function "change_velo()".
249 - Implemented built-in script function "change_note()".
250 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
251 intuitive behavior if used in combination with "change_vol_time()" or
252 "change_tune_time()" respectively: now tuning/volume changes are only
253 assigned (without delay) immediately to a new note if the respective
254 timing function has not been called before, otherwise the volume/tuning
255 changes are automatically faded (before, only the event's time stamp was
256 relevant).
257 - Implemented built-in script function "array_equal()".
258 - Implemented built-in script function "search()".
259 - Implemented built-in script function "sort()".
260 - NKSP Fix: Never suspend "init" event handlers.
261 - Implemented built-in script function "same_region()" (currently only
262 available for gig format engine).
263 - Added built-in script constant "$NKSP_LINEAR".
264 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
265 - Implemented built-in script function "change_vol_curve()".
266 - Implemented built-in script function "change_tune_curve()".
267 - built-in "play_note()" function now supports a sample playback start
268 offset with argument 3, where special value -1 means to use the regular
269 sample offset as defined by the instrument file.
270 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
271 - Built-in variable $EVENT_NOTE is now a read-only variable.
272 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
273 - built-in "play_note()" function now accepts -2 for its fourth argument
274 (note duration) which means the life time of the note shall be sticked
275 to the requested note number of argument 1.
276 - Fix: built-in "play_note()" function now returns 0 as result value if
277 -1 was passed for its fourth argument (note duration) and the respective
278 parent note is already gone.
279 - Implemented built-in script function "change_play_pos()".
280 - NKSP language: Added support for user declared const array variables.
281 - NKSP language: Raise parser warning if array variable is accessed with
282 an index that exceeds the array's size.
283 - NKSP language fix: Unknown characters were not handled correctly.
284 - NKSP language: Added support for "synchronized .. end synchronized"
285 code blocks.
286 - Implemented built-in script function "abort()" which allows to abort
287 another script handler by passing its callback ID.
288 - Fixed potential memory access bug and potential undefined behavior of
289 "init" event handlers.
290 - Print a time stamp along to each call of built-in function "message()".
291 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
292 to retrieve all code blocks filtered out by the preprocessor.
293 - Added built-in script function "fork()".
294 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
295 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
296 - Fixed potential crash when accessing dynamic built-in array variables.
297 - Added built-in script function "callback_status()".
298 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
299 - Added built-in constant $CALLBACK_STATUS_QUEUE.
300 - Added built-in constant $CALLBACK_STATUS_RUNNING.
301 - Removed max. value limitation of built-in functions "change_attack()",
302 "change_decay()" and "change_release()" to i.e. allow passing 2000000
303 for doubling the respective time.
304 - NKSP script editor syntax highlighting API: Fixed app termination due
305 to a lexer start condition stack underrun.
306 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
307 USE_CODE_IF_NOT() preprocessor statements.
308 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
309 can be set to disable all subsequent built-in "message()" function calls
310 on preprocessor level.
311 - Implemented built-in script function "change_sustain()".
312 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
313 to avoid the editor app to crash on ill-formed text input.
314 - Added built-in script function "change_pan_time()".
315 - Added built-in script function "change_pan_curve()".
316 - Added built-in script function "change_cutoff_attack()".
317 - Added built-in script function "change_cutoff_decay()".
318 - Added built-in script function "change_cutoff_sustain()".
319 - Added built-in script function "change_cutoff_release()".
320 - Added built-in script function "change_cutoff_lfo_depth()".
321 - Added built-in script function "change_cutoff_lfo_freq()".
322
323 * Instruments DB:
324 - Fixed memory access bug of general DB access code which lead to
325 undefined behavior.
326 - Cleanup of instruments DB file creation and opening code.
327 - The instrument DB path of linuxsampler's --create-instruments-db argument
328 is now optional, if it is missing, then a default location is used.
329 - Added support for scanning SFZ (.sfz) files.
330 - Added support for scanning Sound Font (.sf2) files.
331 - Fixed undefined DB transaction behavior.
332

338 - Mac OS X: fixed building outside source directory
339 - made sure all source files for hostplugins are included when
340 doing "make dist"
341 - removed empty directories left from the cvs to svn migration
342 - fixed compilation with gcc 4.6.1
343 - another "make dist" fix, for the LV2 plugin
344 - made --enable-pthread-testcancel default on Mac OS X
345 - minor Makefile fix for building lscpparser when build and source

348 configure
349 - Mac OS X: Makefile fix for the install-strip target
350 - fixed compilation with gcc 4.7
351 - fixed configure script error with old autoconf versions
352 - lsatomic.h: use gcc provided atomic functions if building with
353 gcc 4.7 and C++11
354 - modernized configure script
355 - fixed linkage error when building with
356 LDFLAGS="-Wl,--no-undefined" (#190)
357 - fixed compilation with Clang 3.2
358 - removed usage of deprecated Automake variable INCLUDES
359 - fixed building with C++11
360 - build fix: ChangeFlagRelaxed.h was missing in makefile

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

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