* made program change handling in MIDI thread real-time safe by moving
  the logic to a non-RT thread

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 - fixed building with sqlite installed in a non-standard directory
19
20 * general changes:
21 - bugfix: on some POSIX systems instrument editor plugins refused to
22 load as we used a non-portable Linux specific struct field
23 (fixes bug #70, patch by Ronald Baljeu)
24 - fixed endless loop which occured when loading an instrument editor
25 plugin DLL on Windows systems failed
26 - fixed memory leaks that occurred when liblinuxsampler was unloaded
27 - optimized the SynchronizedConfig class so it doesn't wait
28 unnecessarily long after an update
29 - added support for notifying instrument editors on note-on / note-off
30 events (e.g. to highlight the pressed keys on the virtual keyboard
31 of gigedit)
32 - added support for triggering notes by instrument editors (see above)
33 - be verbose on DLL load errors (on Linux)
34 - fixed di-harmonic triangle LFO implementation (this LFO implementation
35 is only used by very few systems, most pick the int math
36 implementation, which is usually faster)
37 - fixes for audio drivers with varying buffer sizes
38 - experimental support for running LinuxSampler as a DSSI, LV2 and
39 VST plugin
40 - notification events for stream/voice count statistics are now sent
41 only when there are actual changes
42 - added memory ordering constraints to improve stability on
43 multi-core and multi-cpu systems
44 - maximum voices and disk streams can now be altered at runtime
45 - fixed CPU feature detection on x86_64 (maybe fixes #108)
46 - automatic stacktrace mechanism is now turned off by default and can
47 be switched on by command line option "--stacktrace" (the automatic
48 stacktrace mechanism seems to be broken on most systems at the moment)
49 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
50 a pointer to the launched InstrumentEditor object
51 - added optional 3rd party user data parameter for following
52 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
53 InstrumentEditor::Launch(),
54 InstrumentManager::LaunchInstrumentEditor()
55 - theoretical fix: made SynchronizedConfig follow C++0x memory
56 model more strictly
57 - fixes for using large audio device buffers
58
59 * audio driver:
60 - removed the nonsense audio channel constraint (which was hard coded to
61 max. 100 audio channels) for most audio drivers
62 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
63 opposed to the LSCP specs
64 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
65 reflected the wrong value
66 - fixed a memory management bug in ASIO driver
67 - Makefile fix: JACK_CFLAGS wasn't used
68 - JACK: use jack_client_open instead of the deprecated
69 jack_client_new
70 - added (experimental) CoreAudio driver
71 - applied old fixes to the ASIO driver that were included in the
72 previous binary release but accidentally never committed to CVS
73 (fixes #117)
74 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
75 win64)
76 - VST: added support for sample rate and buffer size changes
77 - VST: close editor (Fantasia) when the VST is removed
78 - VST: avoid opening Fantasia more than once for each VST instance
79 - VST: export main function as "main" on Linux too (fix for
80 energyXT)
81 - VST: changed number of output channels from one stereo to 16
82 stereo
83 - added channel routing, fxsends and midi maps to the settings
84 stored in the plugin state
85
86 * MIDI driver:
87 - added JACK MIDI driver
88 - dispatch bank select as ordinary CC as well, the user might seriously
89 want to (mis)use it for some purpose ("fixed" in all current MIDI
90 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
91 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
92 CoreMidi or AU
93 - fixed mingw-w64 compilation error in MME driver
94 - made program change handling in MIDI thread real-time safe by
95 moving the logic to a non-RT thread
96
97 * instruments database:
98 - avoid time consuming samples scanning when adding instruments
99 to the instruments database
100 - added support for handling lost files in the instruments database
101 - Implemented option for adding instruments in separate directories
102 in the instruments database
103 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
104 - work-around for missing fnmatch function on Windows to make
105 instrument database compilable
106 - added instrument database support on Windows
107 works with both standalone mode and VST plugin.
108 the instruments DB file is located in
109 %USERPROFILE%\.linuxsampler\instruments.db which allows different
110 databases for each windows user
111 if no DB is present it automatically creates the .linuxsampler subdir
112 and then creates an empty DB
113
114 * Gigasampler format engine:
115 - fixed a memory leak that could happen when a channel was deleted
116 while notes were playing
117 - made it possible to load an instrument even if the audio thread
118 isn't running
119 - added partial support for the "Controller Triggered" MIDI rule,
120 enough for piano gigs with pedal noise samples
121 - minor fix: only mark FX sends as being modified if really the
122 respective FX send MIDI controller was used
123 - added support for GM global device volume SysEx message
124 (can be selected at compile time to either apply globally to the
125 whole sampler [default] or only to the sampler channels that are
126 connected to the respective MIDI input port the SysEx message arrived
127 on)
128 - bugfix: notes triggered at position 0 in the audio buffer were
129 sometimes wrongly killed in the same buffer, causing no sound to
130 be played
131 - added support for chromatic / drumkit mode Roland GS Sysex message
132 which is usally used to switch a part between chromatic sounds and
133 drumkit sounds (as opposed to their common default setting of MIDI
134 part 10 being a drumkit part and all other ones chromatic parts), in
135 LS however one can switch between the first 16 MIDI instrument maps
136 defined for the sampler
137 - made it possible to create multiple sample channels even if the
138 audio thread isn't running
139 - fixed crash when removing channel with active voices (#116)
140 - bugfix: on sample reference changes (instrument editor), only
141 un-cache the respective sample if it's really not used by any
142 sampler engine anymore
143 - re-cache samples in case they were changed by an instrument editor,
144 e.g. when a sample was added while playing (#82)
145 - fixed hanging notes which occured when note-off event had the exact
146 same time stamp as the voice's note-on event and occured both in the
147 same audio fragment cycle (fixes bug #112)
148 - added support for the "fine tune" and "pitch bend range"
149 instrument-level gig parameters
150 - fixed minor artifacts in pitch bend handling
151 - added support for GS Reset SysEx message
152 - allow gig files to use unlimited downward pitch shifting
153 - added a limit check for upward pitch shifting
154 - bugfix: sometimes, when playing a note twice fast, the second
155 note was silent
156 - fixed crash happening when a pitch bend event arrived at the
157 same time a new instrument was loading
158
159 * LSCP server:
160 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
161 react on MIDI data arriving on certain sampler channels (so far only
162 Note-On and Note-Off events are sent via this LSCP event)
163 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
164 react on MIDI data arriving on certain MIDI input devices (so far only
165 Note-On and Note-Off events are sent via this LSCP event)
166 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
167 SET DB_INSTRUMENT FILE_PATH
168 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
169 frontends to send MIDI messages to specific sampler channel
170 - added two additional fields to GET FILE INSTRUMENT INFO command -
171 KEY_BINDINGS and KEYSWITCH_BINDINGS
172 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
173 was incorrect
174 - Optimized the retrieval of the MIDI instrument mappings
175 - added new LSCP command "SET VOICES" to globally alter the maximum
176 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
177 be triggered respectively
178 - added new LSCP command "SET STREAMS" to globally alter the maximum
179 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
180 which will be triggered respectively
181 - bugfix: retry if "select" returns EINTR (this fixes a crash when
182 a gigedit file dialog is opened)
183 - close all connections when LSCPServer is deleted
184 - hard close of all sockets on exit
185 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
186 driver
187
188 * Bug fixes:
189 - fixed a crash which occurs when removing a sampler channel waiting
190 to start instrument loading after another channel
191 - fixed a crash which occurs when removing a sampler channel with
192 instrument loading in progress (bug #113)
193 - fixed termination caused by uncaught exception when adding MIDI
194 instrument with PERSISTENT load mode
195 - fixed possible iterator invalidations when resetting the sampler
196 - fixed memory leaks when issuing the following LSCP commands:
197 GET AUDIO_OUTPUT_DRIVER INFO
198 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
199 GET MIDI_INPUT_DRIVER INFO
200 GET MIDI_INPUT_DRIVER_PARAMETER INFO
201 - fixed possible compilation error when sqlite is not present
202 - fixed orphaned pointers when setting maximum voices limit (bug #118)
203 - fixed crash when changing the audio output device of a sampler
204 channel with loaded instrument and start playing notes
205 - fixed endless loop in Engine::SuspendAll() (bug #120)
206 - fixed a low-level atomic load function that was broken on 64-bit
207 PowerPC, which probably could cause crashes on that platform
208 - fixed a memory management error which could cause a crash when a
209 plugin was unloaded
210 - bugfix: two private structs had the same name, which could cause
211 problems if the linker chose the wrong constructor
212
213
214 Version 0.5.1 (6 December 2007)
215
216 * packaging changes:
217 - added autoconf checks for pthread library
218 - added autoconf check for pthread bug found on certain NPTL-enabled
219 glibc versions (see Gentoo bug report #194076)
220 - added autoconf checks for MS Windows
221
222 * general changes:
223 - bugfix: the thread used by an editor plugin didn't die when the
224 editor closed
225 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
226 out all the space. operator--() did not apply size_mask after
227 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
228 order to avoid problems with the _NonVolatileReader functions.
229 - bugfix: Stream.h: added a missing divide by BytesPerSample in
230 GetWriteSpace(). Since this function is currently only used in
231 the stream's qsort() compare function, it didn't trigger any
232 bugs.
233 - Resampler.h, Synthesizer.h: cubic interpolation now works in
234 24bit mode too. Faster method to read 24bit words on little
235 endian machines (x86): replaced 3 byte reads + shifts with a 1
236 unaligned 32bit read and shift
237 - experimental support for MS Windows (MIDI input via MME, AUDIO
238 output via ASIO)
239 - made handling of SIGINT signal (Ctrl-C) a bit more robust
240 - support for monitoring the total number of active disk streams
241 (new LSCP commands: GET TOTAL_STREAM_COUNT,
242 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
243
244 * AUDIO driver:
245 - added Windows ASIO low latency audio driver
246
247 * MIDI driver:
248 - added MME Windows MIDI driver
249
250 * LSCP server:
251 - added support for Windows style path / filenames, however with
252 forward slash path separators instead of backslash
253 (i.e. "C:/foo/bar.gig")
254 - allow naughty liblscp to send non-string device parameters within
255 apostrophes as well
256 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
257 "LIST FILE INSTRUMENTS <file>" and
258 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
259 about an arbitrary instrument file on the system where the sampler is
260 running on
261
262 Version 0.5.0 (15 October 2007)
263
264 * packaging changes:
265 - config.h is not going to be installed along with liblinuxsampler's
266 API header files anymore
267 - only the API relevant header (and source) files will be exported to
268 the Doxygen API documentation (explicitly listed in Doxyfile.in)
269 - added completely new XCode project files for Mac OSX which is now
270 capable to execute our autoconf environment, thus no need anymore
271 to maintain the compile time configuration file (osx/version.h) for
272 OSX manually (patch by Toshi Nagata)
273 - fixed buggy boolean --enable-foo / --disable-foo configure script
274 parameters
275 - global.h now only covers global definitions that are needed for the
276 C++ API header files, all implementation internal global definitions
277 are now in global_private.h
278 - atomic.h is not exposed to the C++ API anymore
279 - no need to include config.h anymore for using LS's API header files
280 - fixed warnings in API doc generation
281
282 * general changes:
283 - replaced the old, confusing MIDI program change mechanism by a
284 flexible MIDI instrument mapper which allows to map arbitrary
285 (MIDI bank, MIDI program) pairs with arbitrary
286 (engine type, instrument file, file index) triplets which will be
287 loaded on the respective channel when such MIDI program change
288 messages arrive, beside that, each entry allows to define a life-time
289 strategy for the instrument, so the user can define whether the
290 instrument should i.e. be permanently loaded (to be able to switch
291 quickly among sounds) or i.e. loaded just on demand when the
292 respective program change arrives (to safe RAM space), as well as a
293 global volume factor for each entry, so the user can adjust the volume
294 dynamic of his mapped instrument collection without having to modify
295 the instrument files, also one can manage arbitrary amount of such
296 MIDI instrument maps and assign each sampler channel individually
297 a certain map, so that i.e. separation of normal instruments and
298 drumkits is possible
299 - new notification events for tracking changes to audio/MIDI devices,
300 MIDI instrument maps, MIDI instruments, FX sends, global volume.
301 - sampler was limited to load max. 200 instruments in the background
302 due to a constant size RingBuffer FIFO which is now replaced by a
303 dynamic (unlimited) size std::list FIFO
304 - added FX sends, these allow to route audio signals to arbitrary audio
305 output channels for being processed by external effect processors
306 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
307 controllers
308 - global (sampler wide) volume can now be controlled at runtime
309 - Implemented new, improved notification system
310 - fixed compilation errors regarding OSX
311 (patch by Toshi Nagata)
312 - implemented instruments database
313 - added support for escape sequences to the instruments database
314 - added highly experimental support for on-the-fly instrument editing
315 within the sampler's process (by using instrument editor plugins),
316 you'll notice the new "Registered instrument editors:" message on
317 startup, added a new LSCP command:
318 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
319 to spawn a matching instrument editor for the instrument on the
320 given sampler channel, the plugin path can be overridden at compile
321 time with ./configure --enable-plugin-dir=/some/dir
322 - added experimental code for synchronizing instrument editors hosted
323 in the sampler's process to safely edit instruments while playing
324 without a crash (hopefully) by either suspending single regions
325 wherever possible or if unavoidable whole engine(s)
326 - fixed several issues in fundamental "Thread" class: set scheduling
327 policy and priority on thread level, set a minimum stack size for
328 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
329 threads simply inherited properties of starting thread instead of
330 setting their own policy and priority
331 - minor fix in our automatic stack trace mechanism on crashes, the
332 main process did not wait for the stack trace process to finish
333 its output
334 - fixed some minor memory leaks
335 - reenabled assembly features support, at the moment only for
336 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
337 - minor assembly fix in x86 features detection (don't use the PIC
338 register, to avoid relocations in the text segment at runtime)
339 - POSIX callback functions of Thread.h are hidden
340
341 * MIDI driver:
342 - dispatch bank select (MSB and LSB) messages
343
344 * audio driver:
345 - the ALSA audio output driver parameters now reflect the correct
346 parameter value ranges for the respective selected sound card
347 (patch by Till Wimmer, a bit fixed and extended)
348
349 * Gigasampler format engine:
350 - if a filter is used and EG2 finishes before EG1, let the voice
351 die when EG2 has finished (this fixes a problem with clicks and
352 voice starvation for some gigs)
353 - playback is no longer disabled during instrument loading
354 - all notes playing on a channel that changes its instrument keep
355 playing with the old instrument until they get a note off
356 command
357 - EG fix: a release value of zero could cause noises or crash
358 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
359 - EG fine tuning: when attack is zero the EG starts at a level
360 above max sustain level, which means that there is a decay phase
361 even if sustain is 100%
362 - more EG fixes: the level could sometimes go below zero and cause
363 noises or crashes
364 - minor fix of EGDecay (patch by Toshi Nagata)
365 - fixed compiler error when --enable-override-filter-type was
366 supplied to the configure script (fixes #46)
367 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
368 instead of a fix value
369 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
370 127 (solo mode) only kill voices if the respective mode really
371 changed
372
373 * LSCP server:
374 - fixed compile time error for old Bison versions
375 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
376 - parser now supports extended ASCII character set
377 (up to ASCII code 255, i.e. includes now umlauts and accents)
378 - filename arguments in LSCP commands now allow to use escape
379 sequences, that is directly literal as one of: \', \", \\, \n, \r,
380 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
381 code value like \xf2) (fixes bug #24)
382 - the following LSCP commands now also support escape sequences for at
383 least one of their text-based parameters (i.e. name, description):
384 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
385 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
386 "SET DB_INSTRUMENT_DIRECTORY NAME",
387 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
388 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
389 "FIND DB_INSTRUMENT_DIRECTORIES"
390 - returns verbose syntax errors (line and column where syntax error
391 occured, the unexpected character and the actually expected, possible
392 character(s), the latter only if less than 5 possibilities)
393 - made sure that LSCP syntax is not affected by gigedit locale
394 settings
395 - bugfix regarding strings parameter lists: all comma separated lists
396 of strings were treated as being one string containing commas
397 (fixes #57)
398
399 * Bug fixes:
400 - fixed crash occurring on certain LSCP scripts (Bug 39)
401 - another thread safety fix for lscp "load engine" and "set
402 channel audio output device"
403 - fixed a crash which occurs when reassigning the same engine
404 on a sampler channel with connected MIDI device
405 - fixed a crash which occurs when changing the number of ports of a MIDI
406 device connected to a sampler channel to number less then or equal
407 to the index of the port to which the sampler channel is connected.
408 - The previous bindings were not been disconnected when altering
409 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
410 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
411 - The active stream/voice count statistic was incorrect.
412 - notification events were not been sent for some sampler
413 channel changes
414 - added default min and max values to restrict the number of allowed
415 audio output channels and MIDI input ports
416 - the connection to the PCM interface is now closed when destroying
417 an audio output device
418 - files with slash in their path or filename could not be loaded
419
420 * test cases:
421 - updated and fixed (haven't been touched in a while)
422
423 Version 0.4.0 (24 November 2006)
424
425 * packaging changes:
426 - changed deprecated copyright attribute to license; added ldconfig
427 to post-(un)install steps; added devel package for liblinuxsampler;
428 to linuxsampler.spec (RPM)
429 - install necessary development header files for allowing 3rd party
430 applications to link against liblinuxsampler
431 - liblinuxsampler's API documentation can be generated with 'make docs'
432 (Doxygen required)
433 - added benchmark to automatically detect the best triangle LFO
434 implementation (currently either an integer math solution or a
435 di-harmonic approximation), automatic detection can be overriden
436 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
437 configure script argument though (mandatory for cross-compilation)
438 - do not automatically pick optimized gcc flags if the user already
439 provided some on his own (as CXXFLAGS)
440 - added compile time option to disable processing of All-Notes-Off MIDI
441 messages
442 - added compile time options to allow disabling the various audio and
443 MIDI drivers
444 - fixed automatic GCC CPU switch detection on PPC
445 (patch by Ebrahim Mayat)
446
447 * Gigasampler format engine:
448 - extensive synthesis optimization
449 (reimplementation of EGs and LFO(s), removed synthesis parameter
450 prerendering and the synthesis parameter matrix in general, splitting
451 each audio fragment into subfragments now where each subfragment uses
452 constant pitch and filter coefficients. The volume coefficient is
453 linearly interpolated inside a subfragment, unless
454 --disable-interpolate-volume is set.)
455 - fine tuning of the EG modulation parameters
456 - improved filter cutoff calculation by adding support for the
457 following gig parameters: Cutoff freq (used when no cutoff
458 controller is defined), Control invert, Minimum cutoff, Velocity
459 curve and Velocity range. The keyboard tracking now scales
460 cutoff frequency instead of resonance.
461 - added support for gig parameter Resonance.
462 - fixed bug in sysex handling (patch by Juan Linietsky)
463 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
464 which can be overridden with --enable-global-attenuation
465 - EG fixes: made the length of "attack hold" stage more
466 accurate. Release stage can now start before attack stage
467 ends. Cancel release didn't work when sustain was zero. Attack
468 time now has a minimal value to prevent clicks.
469 - fixed pitch changes larger than one octave
470 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
471 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
472 all modes can be altered via standard GM messages, that is CC5 for
473 altering portamento time, CC65 for enabling / disabling portamento
474 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
475 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
476 parameter) and crossfade
477 - added support for the "attenuation controller threshold" gig
478 parameter
479 - added smoothing of volume changes caused by control change
480 messages
481 - sample loop parameters are now taken from the DimensionRegion
482 instead of the wave chunk
483 - fixed keyswitching for v3 gigs with a number of keyswitch splits
484 not equal to a power of two
485 - reimplementation of the filter algorithm. The new filter is more
486 accurate and supports all gig filter types, including bandreject
487 and lowpass turbo.
488 - real support for 24 bit samples - samples are not truncated to
489 16 bits anymore
490 - support for aftertouch (channel pressure, not polyphonic
491 aftertouch)
492 - LFO1 behaviour fixed (dampening from max volume instead of
493 amplifying from 0)
494
495 * LSCP server:
496 - fixed application exit on broken pipe error (fixes bug #20)
497 - fixed the notification messages delay due to lack of
498 network activity (fixes bug #26)
499 - fixed parser bug which occured on space(s) within device parameters
500 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
501
502 * audio driver:
503 - added aRts audio output driver (by no means RT safe)
504
505 * MIDI driver:
506 - fixed legacy sysex code which caused dispatching of MIDI SysEx
507 messages several times instead of once
508 - API extension for MIDI drivers which already supply exact time stamps
509 for events (i.e. for offline rendering based MIDI drivers)
510 - added checks for bad MIDI data
511
512 * linuxsampler application:
513 - show available sampler engine types on startup
514
515 * general changes:
516 - support for muting sampler channels and solo mode of the same, two new
517 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
518 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
519 introduced for this, the behavior is the same like on a mixer console
520 (patch by Grigor Iliev, a bit adjusted). Also added configure option
521 --enable-process-muted-channels which can be used to enable the
522 processing of muted channels.
523 - support for sostenuto pedal
524 - support for monitoring the total number of active voices
525 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
526 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
527 - fixed some memory management errors
528 - fixed some concurrency problems that could lead to crashes when
529 LSCP commands were executed
530 - fixed crash when instrument loading failed previously on the same
531 sampler channel (fixes bug #36)
532
533 Version 0.3.3 (15 July 2005)
534
535 * packaging changes:
536 - fixed compilation with gcc 4.0
537
538 * Gigasampler format engine:
539 - LFO preprocessing was performed even though the respective LFO was
540 disabled by the instrument patch (minor efficiency fix)
541 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
542 for volume ramp downs in the same fragment (needed for current voice
543 stealing implementation) then simply inform the user with a warning
544 about possible click sounds and reduce the volume ramp down
545 appropriately instead of cancelling the audio device connection
546
547 Version 0.3.2 (24 June 2005)
548
549 * packaging changes:
550 - updated autotools build files to compile on OS X
551 (conditional compilation of CoreMIDI and MidiShare drivers)
552 - hand-crafted assembly optimization code can be disabled with
553 './configure --disable-asm' (definitely not recommended)
554 - fixed 'make dist' rule to include all necessary files
555 - require automake (>= 1.5) for 'make -f Makefile.cvs'
556 (due to 'dist-bzip2' automake option)
557
558 * Gigasampler format engine:
559 - support for the gig parameters for "release velocity response" curves
560 - fine tuning of the EGADSR envelope
561 - volume of release triggered samples now depends on note-on velocity,
562 note length and gig parameter "release trigger decay" instead of
563 note-off velocity.
564 - revised voice stealing
565 (fixes crash and endless loop caused by voice stealing)
566 - don't reset scale tuning on instrument or audio output device change
567 - handle key group conflicts right at the beginning of each fragment
568 instead of when the respective voice is actually launched
569 (fixes undefined behavior if stolen voices belonged to a key group -
570 this case was followed by a "killed voice survived" error message)
571 - fixed minor issue with null/silence samples
572 (those stole voices even though they don't need a voice at all which
573 resulted in "voice stealing didn't work out" messages)
574 - don't reset volume, pan, pitch and MIDI controller values on
575 instrument or audio output device change
576
577 * LSCP server:
578 - fixed some crashes (patch by Grigor Iliev, fixes #19)
579 - fixed LSCP event "CHANNEL_INFO" notification
580 (e.g. did not notify on volume changes or MIDI program change events)
581
582 * linuxsampler application:
583 - added command line parameters --lscp-addr and --lscp-port to override
584 default IP address and port of LSCP server
585
586 Version 0.3.1 (24 May 2005)
587
588 * initial release
