File size: 30036 byte(s)
* added channel routing, fxsends and midi maps to the settings stored
  in the plugin state

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5 causing e.g. the libgig test to fail when
6 "./configure --disable-jack-driver" was used
7 (patch by Alexis Ballier)
8 - fixed compilation with gcc 4.3
9 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 - fixed configure so it detects x86_64 (#107)
11 - fixes for building with newer MinGW versions
12 - fix for building with bison 2.4 (#111)
13 - fixed building with libgig installed in a non-standard directory
14 - minor fix in configure for mmsystem.h detection on MinGW
15 - Windows: look for editor plugins and Fantasia using base
16 directory of liblinuxsampler dll
17 - configure script fix: removed unconditional use of SSE
18
19 * general changes:
20 - bugfix: on some POSIX systems instrument editor plugins refused to
21 load as we used a non-portable Linux specific struct field
22 (fixes bug #70, patch by Ronald Baljeu)
23 - fixed endless loop which occured when loading an instrument editor
24 plugin DLL on Windows systems failed
25 - fixed memory leaks that occurred when liblinuxsampler was unloaded
26 - optimized the SynchronizedConfig class so it doesn't wait
27 unnecessarily long after an update
28 - added support for notifying instrument editors on note-on / note-off
29 events (e.g. to highlight the pressed keys on the virtual keyboard
30 of gigedit)
31 - added support for triggering notes by instrument editors (see above)
32 - be verbose on DLL load errors (on Linux)
33 - fixed di-harmonic triangle LFO implementation (this LFO implementation
34 is only used by very few systems, most pick the int math
35 implementation, which is usually faster)
36 - fixes for audio drivers with varying buffer sizes
37 - experimental support for running LinuxSampler as a DSSI, LV2 and
38 VST plugin
39 - notification events for stream/voice count statistics are now sent
40 only when there are actual changes
41 - added memory ordering constraints to improve stability on
42 multi-core and multi-cpu systems
43 - maximum voices and disk streams can now be altered at runtime
44 - fixed CPU feature detection on x86_64 (maybe fixes #108)
45 - automatic stacktrace mechanism is now turned off by default and can
46 be switched on by command line option "--stacktrace" (the automatic
47 stacktrace mechanism seems to be broken on most systems at the moment)
48 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49 a pointer to the launched InstrumentEditor object
50 - added optional 3rd party user data parameter for following
51 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52 InstrumentEditor::Launch(),
53 InstrumentManager::LaunchInstrumentEditor()
54 - theoretical fix: made SynchronizedConfig follow C++0x memory
55 model more strictly
56 - fixes for using large audio device buffers
57
58 * audio driver:
59 - removed the nonsense audio channel constraint (which was hard coded to
60 max. 100 audio channels) for most audio drivers
61 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62 opposed to the LSCP specs
63 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64 reflected the wrong value
65 - fixed a memory management bug in ASIO driver
66 - Makefile fix: JACK_CFLAGS wasn't used
67 - JACK: use jack_client_open instead of the deprecated
68 jack_client_new
69 - added (experimental) CoreAudio driver
70 - applied old fixes to the ASIO driver that were included in the
71 previous binary release but accidentally never committed to CVS
72 (fixes #117)
73 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74 win64)
75 - VST: added support for sample rate and buffer size changes
76 - VST: close editor (Fantasia) when the VST is removed
77 - VST: avoid opening Fantasia more than once for each VST instance
78 - VST: export main function as "main" on Linux too (fix for
79 energyXT)
80 - VST: changed number of output channels from one stereo to 16
81 stereo
82 - added channel routing, fxsends and midi maps to the settings
83 stored in the plugin state
84
85 * MIDI driver:
86 - added JACK MIDI driver
87 - dispatch bank select as ordinary CC as well, the user might seriously
88 want to (mis)use it for some purpose ("fixed" in all current MIDI
89 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
90 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
91 CoreMidi or AU
92 - fixed mingw-w64 compilation error in MME driver
93
94 * instruments database:
95 - avoid time consuming samples scanning when adding instruments
96 to the instruments database
97 - added support for handling lost files in the instruments database
98 - Implemented option for adding instruments in separate directories
99 in the instruments database
100 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
101 - work-around for missing fnmatch function on Windows to make
102 instrument database compilable
103 - added instrument database support on Windows
104 works with both standalone mode and VST plugin.
105 the instruments DB file is located in
106 %USERPROFILE%\.linuxsampler\instruments.db which allows different
107 databases for each windows user
108 if no DB is present it automatically creates the .linuxsampler subdir
109 and then creates an empty DB
110
111 * Gigasampler format engine:
112 - fixed a memory leak that could happen when a channel was deleted
113 while notes were playing
114 - made it possible to load an instrument even if the audio thread
115 isn't running
116 - added partial support for the "Controller Triggered" MIDI rule,
117 enough for piano gigs with pedal noise samples
118 - minor fix: only mark FX sends as being modified if really the
119 respective FX send MIDI controller was used
120 - added support for GM global device volume SysEx message
121 (can be selected at compile time to either apply globally to the
122 whole sampler [default] or only to the sampler channels that are
123 connected to the respective MIDI input port the SysEx message arrived
124 on)
125 - bugfix: notes triggered at position 0 in the audio buffer were
126 sometimes wrongly killed in the same buffer, causing no sound to
127 be played
128 - added support for chromatic / drumkit mode Roland GS Sysex message
129 which is usally used to switch a part between chromatic sounds and
130 drumkit sounds (as opposed to their common default setting of MIDI
131 part 10 being a drumkit part and all other ones chromatic parts), in
132 LS however one can switch between the first 16 MIDI instrument maps
133 defined for the sampler
134 - made it possible to create multiple sample channels even if the
135 audio thread isn't running
136 - fixed crash when removing channel with active voices (#116)
137 - bugfix: on sample reference changes (instrument editor), only
138 un-cache the respective sample if it's really not used by any
139 sampler engine anymore
140 - re-cache samples in case they were changed by an instrument editor,
141 e.g. when a sample was added while playing (#82)
142 - fixed hanging notes which occured when note-off event had the exact
143 same time stamp as the voice's note-on event and occured both in the
144 same audio fragment cycle (fixes bug #112)
145 - added support for the "fine tune" and "pitch bend range"
146 instrument-level gig parameters
147 - fixed minor artifacts in pitch bend handling
148 - added support for GS Reset SysEx message
149 - allow gig files to use unlimited downward pitch shifting
150 - added a limit check for upward pitch shifting
151 - bugfix: sometimes, when playing a note twice fast, the second
152 note was silent
153
154 * LSCP server:
155 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
156 react on MIDI data arriving on certain sampler channels (so far only
157 Note-On and Note-Off events are sent via this LSCP event)
158 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
159 react on MIDI data arriving on certain MIDI input devices (so far only
160 Note-On and Note-Off events are sent via this LSCP event)
161 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
162 SET DB_INSTRUMENT FILE_PATH
163 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
164 frontends to send MIDI messages to specific sampler channel
165 - added two additional fields to GET FILE INSTRUMENT INFO command -
166 KEY_BINDINGS and KEYSWITCH_BINDINGS
167 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
168 was incorrect
169 - Optimized the retrieval of the MIDI instrument mappings
170 - added new LSCP command "SET VOICES" to globally alter the maximum
171 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
172 be triggered respectively
173 - added new LSCP command "SET STREAMS" to globally alter the maximum
174 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
175 which will be triggered respectively
176 - bugfix: retry if "select" returns EINTR (this fixes a crash when
177 a gigedit file dialog is opened)
178 - close all connections when LSCPServer is deleted
179 - hard close of all sockets on exit
180 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
181 driver
182
183 * Bug fixes:
184 - fixed a crash which occurs when removing a sampler channel waiting
185 to start instrument loading after another channel
186 - fixed a crash which occurs when removing a sampler channel with
187 instrument loading in progress (bug #113)
188 - fixed termination caused by uncaught exception when adding MIDI
189 instrument with PERSISTENT load mode
190 - fixed possible iterator invalidations when resetting the sampler
191 - fixed memory leaks when issuing the following LSCP commands:
192 GET AUDIO_OUTPUT_DRIVER INFO
193 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
194 GET MIDI_INPUT_DRIVER INFO
195 GET MIDI_INPUT_DRIVER_PARAMETER INFO
196 - fixed possible compilation error when sqlite is not present
197 - fixed orphaned pointers when setting maximum voices limit (bug #118)
198 - fixed crash when changing the audio output device of a sampler
199 channel with loaded instrument and start playing notes
200 - fixed endless loop in Engine::SuspendAll() (bug #120)
201 - fixed a low-level atomic load function that was broken on 64-bit
202 PowerPC, which probably could cause crashes on that platform
203 - fixed a memory management error which could cause a crash when a
204 plugin was unloaded
205 - bugfix: two private structs had the same name, which could cause
206 problems if the linker chose the wrong constructor
207
208
209 Version 0.5.1 (6 December 2007)
210
211 * packaging changes:
212 - added autoconf checks for pthread library
213 - added autoconf check for pthread bug found on certain NPTL-enabled
214 glibc versions (see Gentoo bug report #194076)
215 - added autoconf checks for MS Windows
216
217 * general changes:
218 - bugfix: the thread used by an editor plugin didn't die when the
219 editor closed
220 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
221 out all the space. operator--() did not apply size_mask after
222 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
223 order to avoid problems with the _NonVolatileReader functions.
224 - bugfix: Stream.h: added a missing divide by BytesPerSample in
225 GetWriteSpace(). Since this function is currently only used in
226 the stream's qsort() compare function, it didn't trigger any
227 bugs.
228 - Resampler.h, Synthesizer.h: cubic interpolation now works in
229 24bit mode too. Faster method to read 24bit words on little
230 endian machines (x86): replaced 3 byte reads + shifts with a 1
231 unaligned 32bit read and shift
232 - experimental support for MS Windows (MIDI input via MME, AUDIO
233 output via ASIO)
234 - made handling of SIGINT signal (Ctrl-C) a bit more robust
235 - support for monitoring the total number of active disk streams
236 (new LSCP commands: GET TOTAL_STREAM_COUNT,
237 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
238
239 * AUDIO driver:
240 - added Windows ASIO low latency audio driver
241
242 * MIDI driver:
243 - added MME Windows MIDI driver
244
245 * LSCP server:
246 - added support for Windows style path / filenames, however with
247 forward slash path separators instead of backslash
248 (i.e. "C:/foo/bar.gig")
249 - allow naughty liblscp to send non-string device parameters within
250 apostrophes as well
251 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
252 "LIST FILE INSTRUMENTS <file>" and
253 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
254 about an arbitrary instrument file on the system where the sampler is
255 running on
256
257 Version 0.5.0 (15 October 2007)
258
259 * packaging changes:
260 - config.h is not going to be installed along with liblinuxsampler's
261 API header files anymore
262 - only the API relevant header (and source) files will be exported to
263 the Doxygen API documentation (explicitly listed in Doxyfile.in)
264 - added completely new XCode project files for Mac OSX which is now
265 capable to execute our autoconf environment, thus no need anymore
266 to maintain the compile time configuration file (osx/version.h) for
267 OSX manually (patch by Toshi Nagata)
268 - fixed buggy boolean --enable-foo / --disable-foo configure script
269 parameters
270 - global.h now only covers global definitions that are needed for the
271 C++ API header files, all implementation internal global definitions
272 are now in global_private.h
273 - atomic.h is not exposed to the C++ API anymore
274 - no need to include config.h anymore for using LS's API header files
275 - fixed warnings in API doc generation
276
277 * general changes:
278 - replaced the old, confusing MIDI program change mechanism by a
279 flexible MIDI instrument mapper which allows to map arbitrary
280 (MIDI bank, MIDI program) pairs with arbitrary
281 (engine type, instrument file, file index) triplets which will be
282 loaded on the respective channel when such MIDI program change
283 messages arrive, beside that, each entry allows to define a life-time
284 strategy for the instrument, so the user can define whether the
285 instrument should i.e. be permanently loaded (to be able to switch
286 quickly among sounds) or i.e. loaded just on demand when the
287 respective program change arrives (to safe RAM space), as well as a
288 global volume factor for each entry, so the user can adjust the volume
289 dynamic of his mapped instrument collection without having to modify
290 the instrument files, also one can manage arbitrary amount of such
291 MIDI instrument maps and assign each sampler channel individually
292 a certain map, so that i.e. separation of normal instruments and
293 drumkits is possible
294 - new notification events for tracking changes to audio/MIDI devices,
295 MIDI instrument maps, MIDI instruments, FX sends, global volume.
296 - sampler was limited to load max. 200 instruments in the background
297 due to a constant size RingBuffer FIFO which is now replaced by a
298 dynamic (unlimited) size std::list FIFO
299 - added FX sends, these allow to route audio signals to arbitrary audio
300 output channels for being processed by external effect processors
301 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
302 controllers
303 - global (sampler wide) volume can now be controlled at runtime
304 - Implemented new, improved notification system
305 - fixed compilation errors regarding OSX
306 (patch by Toshi Nagata)
307 - implemented instruments database
308 - added support for escape sequences to the instruments database
309 - added highly experimental support for on-the-fly instrument editing
310 within the sampler's process (by using instrument editor plugins),
311 you'll notice the new "Registered instrument editors:" message on
312 startup, added a new LSCP command:
313 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
314 to spawn a matching instrument editor for the instrument on the
315 given sampler channel, the plugin path can be overridden at compile
316 time with ./configure --enable-plugin-dir=/some/dir
317 - added experimental code for synchronizing instrument editors hosted
318 in the sampler's process to safely edit instruments while playing
319 without a crash (hopefully) by either suspending single regions
320 wherever possible or if unavoidable whole engine(s)
321 - fixed several issues in fundamental "Thread" class: set scheduling
322 policy and priority on thread level, set a minimum stack size for
323 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
324 threads simply inherited properties of starting thread instead of
325 setting their own policy and priority
326 - minor fix in our automatic stack trace mechanism on crashes, the
327 main process did not wait for the stack trace process to finish
328 its output
329 - fixed some minor memory leaks
330 - reenabled assembly features support, at the moment only for
331 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
332 - minor assembly fix in x86 features detection (don't use the PIC
333 register, to avoid relocations in the text segment at runtime)
334 - POSIX callback functions of Thread.h are hidden
335
336 * MIDI driver:
337 - dispatch bank select (MSB and LSB) messages
338
339 * audio driver:
340 - the ALSA audio output driver parameters now reflect the correct
341 parameter value ranges for the respective selected sound card
342 (patch by Till Wimmer, a bit fixed and extended)
343
344 * Gigasampler format engine:
345 - if a filter is used and EG2 finishes before EG1, let the voice
346 die when EG2 has finished (this fixes a problem with clicks and
347 voice starvation for some gigs)
348 - playback is no longer disabled during instrument loading
349 - all notes playing on a channel that changes its instrument keep
350 playing with the old instrument until they get a note off
351 command
352 - EG fix: a release value of zero could cause noises or crash
353 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
354 - EG fine tuning: when attack is zero the EG starts at a level
355 above max sustain level, which means that there is a decay phase
356 even if sustain is 100%
357 - more EG fixes: the level could sometimes go below zero and cause
358 noises or crashes
359 - minor fix of EGDecay (patch by Toshi Nagata)
360 - fixed compiler error when --enable-override-filter-type was
361 supplied to the configure script (fixes #46)
362 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
363 instead of a fix value
364 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
365 127 (solo mode) only kill voices if the respective mode really
366 changed
367
368 * LSCP server:
369 - fixed compile time error for old Bison versions
370 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
371 - parser now supports extended ASCII character set
372 (up to ASCII code 255, i.e. includes now umlauts and accents)
373 - filename arguments in LSCP commands now allow to use escape
374 sequences, that is directly literal as one of: \', \", \\, \n, \r,
375 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
376 code value like \xf2) (fixes bug #24)
377 - the following LSCP commands now also support escape sequences for at
378 least one of their text-based parameters (i.e. name, description):
379 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
380 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
381 "SET DB_INSTRUMENT_DIRECTORY NAME",
382 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
383 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
384 "FIND DB_INSTRUMENT_DIRECTORIES"
385 - returns verbose syntax errors (line and column where syntax error
386 occured, the unexpected character and the actually expected, possible
387 character(s), the latter only if less than 5 possibilities)
388 - made sure that LSCP syntax is not affected by gigedit locale
389 settings
390 - bugfix regarding strings parameter lists: all comma separated lists
391 of strings were treated as being one string containing commas
392 (fixes #57)
393
394 * Bug fixes:
395 - fixed crash occurring on certain LSCP scripts (Bug 39)
396 - another thread safety fix for lscp "load engine" and "set
397 channel audio output device"
398 - fixed a crash which occurs when reassigning the same engine
399 on a sampler channel with connected MIDI device
400 - fixed a crash which occurs when changing the number of ports of a MIDI
401 device connected to a sampler channel to number less then or equal
402 to the index of the port to which the sampler channel is connected.
403 - The previous bindings were not been disconnected when altering
404 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
405 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
406 - The active stream/voice count statistic was incorrect.
407 - notification events were not been sent for some sampler
408 channel changes
409 - added default min and max values to restrict the number of allowed
410 audio output channels and MIDI input ports
411 - the connection to the PCM interface is now closed when destroying
412 an audio output device
413 - files with slash in their path or filename could not be loaded
414
415 * test cases:
416 - updated and fixed (haven't been touched in a while)
417
418 Version 0.4.0 (24 November 2006)
419
420 * packaging changes:
421 - changed deprecated copyright attribute to license; added ldconfig
422 to post-(un)install steps; added devel package for liblinuxsampler;
423 to linuxsampler.spec (RPM)
424 - install necessary development header files for allowing 3rd party
425 applications to link against liblinuxsampler
426 - liblinuxsampler's API documentation can be generated with 'make docs'
427 (Doxygen required)
428 - added benchmark to automatically detect the best triangle LFO
429 implementation (currently either an integer math solution or a
430 di-harmonic approximation), automatic detection can be overriden
431 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
432 configure script argument though (mandatory for cross-compilation)
433 - do not automatically pick optimized gcc flags if the user already
434 provided some on his own (as CXXFLAGS)
435 - added compile time option to disable processing of All-Notes-Off MIDI
436 messages
437 - added compile time options to allow disabling the various audio and
438 MIDI drivers
439 - fixed automatic GCC CPU switch detection on PPC
440 (patch by Ebrahim Mayat)
441
442 * Gigasampler format engine:
443 - extensive synthesis optimization
444 (reimplementation of EGs and LFO(s), removed synthesis parameter
445 prerendering and the synthesis parameter matrix in general, splitting
446 each audio fragment into subfragments now where each subfragment uses
447 constant pitch and filter coefficients. The volume coefficient is
448 linearly interpolated inside a subfragment, unless
449 --disable-interpolate-volume is set.)
450 - fine tuning of the EG modulation parameters
451 - improved filter cutoff calculation by adding support for the
452 following gig parameters: Cutoff freq (used when no cutoff
453 controller is defined), Control invert, Minimum cutoff, Velocity
454 curve and Velocity range. The keyboard tracking now scales
455 cutoff frequency instead of resonance.
456 - added support for gig parameter Resonance.
457 - fixed bug in sysex handling (patch by Juan Linietsky)
458 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
459 which can be overridden with --enable-global-attenuation
460 - EG fixes: made the length of "attack hold" stage more
461 accurate. Release stage can now start before attack stage
462 ends. Cancel release didn't work when sustain was zero. Attack
463 time now has a minimal value to prevent clicks.
464 - fixed pitch changes larger than one octave
465 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
466 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
467 all modes can be altered via standard GM messages, that is CC5 for
468 altering portamento time, CC65 for enabling / disabling portamento
469 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
470 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
471 parameter) and crossfade
472 - added support for the "attenuation controller threshold" gig
473 parameter
474 - added smoothing of volume changes caused by control change
475 messages
476 - sample loop parameters are now taken from the DimensionRegion
477 instead of the wave chunk
478 - fixed keyswitching for v3 gigs with a number of keyswitch splits
479 not equal to a power of two
480 - reimplementation of the filter algorithm. The new filter is more
481 accurate and supports all gig filter types, including bandreject
482 and lowpass turbo.
483 - real support for 24 bit samples - samples are not truncated to
484 16 bits anymore
485 - support for aftertouch (channel pressure, not polyphonic
486 aftertouch)
487 - LFO1 behaviour fixed (dampening from max volume instead of
488 amplifying from 0)
489
490 * LSCP server:
491 - fixed application exit on broken pipe error (fixes bug #20)
492 - fixed the notification messages delay due to lack of
493 network activity (fixes bug #26)
494 - fixed parser bug which occured on space(s) within device parameters
495 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
496
497 * audio driver:
498 - added aRts audio output driver (by no means RT safe)
499
500 * MIDI driver:
501 - fixed legacy sysex code which caused dispatching of MIDI SysEx
502 messages several times instead of once
503 - API extension for MIDI drivers which already supply exact time stamps
504 for events (i.e. for offline rendering based MIDI drivers)
505 - added checks for bad MIDI data
506
507 * linuxsampler application:
508 - show available sampler engine types on startup
509
510 * general changes:
511 - support for muting sampler channels and solo mode of the same, two new
512 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
513 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
514 introduced for this, the behavior is the same like on a mixer console
515 (patch by Grigor Iliev, a bit adjusted). Also added configure option
516 --enable-process-muted-channels which can be used to enable the
517 processing of muted channels.
518 - support for sostenuto pedal
519 - support for monitoring the total number of active voices
520 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
521 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
522 - fixed some memory management errors
523 - fixed some concurrency problems that could lead to crashes when
524 LSCP commands were executed
525 - fixed crash when instrument loading failed previously on the same
526 sampler channel (fixes bug #36)
527
528 Version 0.3.3 (15 July 2005)
529
530 * packaging changes:
531 - fixed compilation with gcc 4.0
532
533 * Gigasampler format engine:
534 - LFO preprocessing was performed even though the respective LFO was
535 disabled by the instrument patch (minor efficiency fix)
536 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
537 for volume ramp downs in the same fragment (needed for current voice
538 stealing implementation) then simply inform the user with a warning
539 about possible click sounds and reduce the volume ramp down
540 appropriately instead of cancelling the audio device connection
541
542 Version 0.3.2 (24 June 2005)
543
544 * packaging changes:
545 - updated autotools build files to compile on OS X
546 (conditional compilation of CoreMIDI and MidiShare drivers)
547 - hand-crafted assembly optimization code can be disabled with
548 './configure --disable-asm' (definitely not recommended)
549 - fixed 'make dist' rule to include all necessary files
550 - require automake (>= 1.5) for 'make -f Makefile.cvs'
551 (due to 'dist-bzip2' automake option)
552
553 * Gigasampler format engine:
554 - support for the gig parameters for "release velocity response" curves
555 - fine tuning of the EGADSR envelope
556 - volume of release triggered samples now depends on note-on velocity,
557 note length and gig parameter "release trigger decay" instead of
558 note-off velocity.
559 - revised voice stealing
560 (fixes crash and endless loop caused by voice stealing)
561 - don't reset scale tuning on instrument or audio output device change
562 - handle key group conflicts right at the beginning of each fragment
563 instead of when the respective voice is actually launched
564 (fixes undefined behavior if stolen voices belonged to a key group -
565 this case was followed by a "killed voice survived" error message)
566 - fixed minor issue with null/silence samples
567 (those stole voices even though they don't need a voice at all which
568 resulted in "voice stealing didn't work out" messages)
569 - don't reset volume, pan, pitch and MIDI controller values on
570 instrument or audio output device change
571
572 * LSCP server:
573 - fixed some crashes (patch by Grigor Iliev, fixes #19)
574 - fixed LSCP event "CHANNEL_INFO" notification
575 (e.g. did not notify on volume changes or MIDI program change events)
576
577 * linuxsampler application:
578 - added command line parameters --lscp-addr and --lscp-port to override
579 default IP address and port of LSCP server
580
581 Version 0.3.1 (24 May 2005)
582
583 * initial release
