Tue Jul 14 18:25:11 2009 UTC (10 years, 2 months ago) by persson
File size: 30813 byte(s)
* fixed instrument database recursive import, which was broken on
  Windows

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 (look in the same directory and one
17 directory above)
18 - configure script fix: removed unconditional use of SSE
19 - fixed building with sqlite installed in a non-standard directory
20 - when cross-compiling, don't try to create instruments.db
21 - fix for new mingw-w64 version, which has usleep
22
23 * general changes:
24 - bugfix: on some POSIX systems instrument editor plugins refused to
25 load as we used a non-portable Linux specific struct field
26 (fixes bug #70, patch by Ronald Baljeu)
27 - fixed endless loop which occured when loading an instrument editor
28 plugin DLL on Windows systems failed
29 - fixed memory leaks that occurred when liblinuxsampler was unloaded
30 - optimized the SynchronizedConfig class so it doesn't wait
31 unnecessarily long after an update
32 - added support for notifying instrument editors on note-on / note-off
33 events (e.g. to highlight the pressed keys on the virtual keyboard
34 of gigedit)
35 - added support for triggering notes by instrument editors (see above)
36 - be verbose on DLL load errors (on Linux)
37 - fixed di-harmonic triangle LFO implementation (this LFO implementation
38 is only used by very few systems, most pick the int math
39 implementation, which is usually faster)
40 - fixes for audio drivers with varying buffer sizes
41 - experimental support for running LinuxSampler as a DSSI, LV2 and
42 VST plugin
43 - notification events for stream/voice count statistics are now sent
44 only when there are actual changes
45 - added memory ordering constraints to improve stability on
46 multi-core and multi-cpu systems
47 - maximum voices and disk streams can now be altered at runtime
48 - fixed CPU feature detection on x86_64 (maybe fixes #108)
49 - automatic stacktrace mechanism is now turned off by default and can
50 be switched on by command line option "--stacktrace" (the automatic
51 stacktrace mechanism seems to be broken on most systems at the moment)
52 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
53 a pointer to the launched InstrumentEditor object
54 - added optional 3rd party user data parameter for following
55 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
56 InstrumentEditor::Launch(),
57 InstrumentManager::LaunchInstrumentEditor()
58 - theoretical fix: made SynchronizedConfig follow C++0x memory
59 model more strictly
60 - fixes for using large audio device buffers
61
62 * audio driver:
63 - removed the nonsense audio channel constraint (which was hard coded to
64 max. 100 audio channels) for most audio drivers
65 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
66 opposed to the LSCP specs
67 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
68 reflected the wrong value
69 - fixed a memory management bug in ASIO driver
70 - Makefile fix: JACK_CFLAGS wasn't used
71 - JACK: use jack_client_open instead of the deprecated
72 jack_client_new
73 - added (experimental) CoreAudio driver
74 - applied old fixes to the ASIO driver that were included in the
75 previous binary release but accidentally never committed to CVS
76 (fixes #117)
77 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
78 win64)
79 - VST: added support for sample rate and buffer size changes
80 - VST: close editor (Fantasia) when the VST is removed
81 - VST: avoid opening Fantasia more than once for each VST instance
82 - VST: export main function as "main" on Linux too (fix for
83 energyXT)
84 - VST: changed number of output channels from one stereo to 16
85 stereo
86 - added channel routing, fxsends and midi maps to the settings
87 stored in the plugin state
88 - performance optimization of AudioChannel::MixTo() and
89 AudioChannel::CopyTo() methods using GCC vector exensions
90 (if available)
91
92 * MIDI driver:
93 - added JACK MIDI driver
94 - dispatch bank select as ordinary CC as well, the user might seriously
95 want to (mis)use it for some purpose ("fixed" in all current MIDI
96 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
97 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
98 CoreMidi or AU
99 - fixed mingw-w64 compilation error in MME driver
100 - made program change handling in MIDI thread real-time safe by
101 moving the logic to a non-RT thread
102
103 * instruments database:
104 - avoid time consuming samples scanning when adding instruments
105 to the instruments database
106 - added support for handling lost files in the instruments database
107 - Implemented option for adding instruments in separate directories
108 in the instruments database
109 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
110 - work-around for missing fnmatch function on Windows to make
111 instrument database compilable
112 - added instrument database support on Windows
113 works with both standalone mode and VST plugin.
114 the instruments DB file is located in
115 %USERPROFILE%\.linuxsampler\instruments.db which allows different
116 databases for each windows user
117 if no DB is present it automatically creates the .linuxsampler subdir
118 and then creates an empty DB
119 - fixed recursive import, which was broken on Windows
120
121 * Gigasampler format engine:
122 - fixed a memory leak that could happen when a channel was deleted
123 while notes were playing
124 - made it possible to load an instrument even if the audio thread
125 isn't running
126 - added partial support for the "Controller Triggered" MIDI rule,
127 enough for piano gigs with pedal noise samples
128 - minor fix: only mark FX sends as being modified if really the
129 respective FX send MIDI controller was used
130 - added support for GM global device volume SysEx message
131 (can be selected at compile time to either apply globally to the
132 whole sampler [default] or only to the sampler channels that are
133 connected to the respective MIDI input port the SysEx message arrived
134 on)
135 - bugfix: notes triggered at position 0 in the audio buffer were
136 sometimes wrongly killed in the same buffer, causing no sound to
137 be played
138 - added support for chromatic / drumkit mode Roland GS Sysex message
139 which is usally used to switch a part between chromatic sounds and
140 drumkit sounds (as opposed to their common default setting of MIDI
141 part 10 being a drumkit part and all other ones chromatic parts), in
142 LS however one can switch between the first 16 MIDI instrument maps
143 defined for the sampler
144 - made it possible to create multiple sample channels even if the
145 audio thread isn't running
146 - fixed crash when removing channel with active voices (#116)
147 - bugfix: on sample reference changes (instrument editor), only
148 un-cache the respective sample if it's really not used by any
149 sampler engine anymore
150 - re-cache samples in case they were changed by an instrument editor,
151 e.g. when a sample was added while playing (#82)
152 - fixed hanging notes which occured when note-off event had the exact
153 same time stamp as the voice's note-on event and occured both in the
154 same audio fragment cycle (fixes bug #112)
155 - added support for the "fine tune" and "pitch bend range"
156 instrument-level gig parameters
157 - fixed minor artifacts in pitch bend handling
158 - added support for GS Reset SysEx message
159 - allow gig files to use unlimited downward pitch shifting
160 - added a limit check for upward pitch shifting
161 - bugfix: sometimes, when playing a note twice fast, the second
162 note was silent
163 - fixed crash happening when a pitch bend event arrived at the
164 same time a new instrument was loading
165
166 * LSCP server:
167 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
168 react on MIDI data arriving on certain sampler channels (so far only
169 Note-On and Note-Off events are sent via this LSCP event)
170 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
171 react on MIDI data arriving on certain MIDI input devices (so far only
172 Note-On and Note-Off events are sent via this LSCP event)
173 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
174 SET DB_INSTRUMENT FILE_PATH
175 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
176 frontends to send MIDI messages to specific sampler channel
177 - added two additional fields to GET FILE INSTRUMENT INFO command -
178 KEY_BINDINGS and KEYSWITCH_BINDINGS
179 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
180 was incorrect
181 - Optimized the retrieval of the MIDI instrument mappings
182 - added new LSCP command "SET VOICES" to globally alter the maximum
183 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
184 be triggered respectively
185 - added new LSCP command "SET STREAMS" to globally alter the maximum
186 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
187 which will be triggered respectively
188 - bugfix: retry if "select" returns EINTR (this fixes a crash when
189 a gigedit file dialog is opened)
190 - close all connections when LSCPServer is deleted
191 - hard close of all sockets on exit
192 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
193 driver
194
195 * Bug fixes:
196 - fixed a crash which occurs when removing a sampler channel waiting
197 to start instrument loading after another channel
198 - fixed a crash which occurs when removing a sampler channel with
199 instrument loading in progress (bug #113)
200 - fixed termination caused by uncaught exception when adding MIDI
201 instrument with PERSISTENT load mode
202 - fixed possible iterator invalidations when resetting the sampler
203 - fixed memory leaks when issuing the following LSCP commands:
204 GET AUDIO_OUTPUT_DRIVER INFO
205 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
206 GET MIDI_INPUT_DRIVER INFO
207 GET MIDI_INPUT_DRIVER_PARAMETER INFO
208 - fixed possible compilation error when sqlite is not present
209 - fixed orphaned pointers when setting maximum voices limit (bug #118)
210 - fixed crash when changing the audio output device of a sampler
211 channel with loaded instrument and start playing notes
212 - fixed endless loop in Engine::SuspendAll() (bug #120)
213 - fixed a low-level atomic load function that was broken on 64-bit
214 PowerPC, which probably could cause crashes on that platform
215 - fixed a memory management error which could cause a crash when a
216 plugin was unloaded
217 - bugfix: two private structs had the same name, which could cause
218 problems if the linker chose the wrong constructor
219 - fixed low-level ConditionServer usage bug that caused lockups on
220 Windows
221
222
223 Version 0.5.1 (6 December 2007)
224
225 * packaging changes:
226 - added autoconf checks for pthread library
227 - added autoconf check for pthread bug found on certain NPTL-enabled
228 glibc versions (see Gentoo bug report #194076)
229 - added autoconf checks for MS Windows
230
231 * general changes:
232 - bugfix: the thread used by an editor plugin didn't die when the
233 editor closed
234 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
235 out all the space. operator--() did not apply size_mask after
236 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
237 order to avoid problems with the _NonVolatileReader functions.
238 - bugfix: Stream.h: added a missing divide by BytesPerSample in
239 GetWriteSpace(). Since this function is currently only used in
240 the stream's qsort() compare function, it didn't trigger any
241 bugs.
242 - Resampler.h, Synthesizer.h: cubic interpolation now works in
243 24bit mode too. Faster method to read 24bit words on little
244 endian machines (x86): replaced 3 byte reads + shifts with a 1
245 unaligned 32bit read and shift
246 - experimental support for MS Windows (MIDI input via MME, AUDIO
247 output via ASIO)
248 - made handling of SIGINT signal (Ctrl-C) a bit more robust
249 - support for monitoring the total number of active disk streams
250 (new LSCP commands: GET TOTAL_STREAM_COUNT,
251 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
252
253 * AUDIO driver:
254 - added Windows ASIO low latency audio driver
255
256 * MIDI driver:
257 - added MME Windows MIDI driver
258
259 * LSCP server:
260 - added support for Windows style path / filenames, however with
261 forward slash path separators instead of backslash
262 (i.e. "C:/foo/bar.gig")
263 - allow naughty liblscp to send non-string device parameters within
264 apostrophes as well
265 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
266 "LIST FILE INSTRUMENTS <file>" and
267 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
268 about an arbitrary instrument file on the system where the sampler is
269 running on
270
271 Version 0.5.0 (15 October 2007)
272
273 * packaging changes:
274 - config.h is not going to be installed along with liblinuxsampler's
275 API header files anymore
276 - only the API relevant header (and source) files will be exported to
277 the Doxygen API documentation (explicitly listed in Doxyfile.in)
278 - added completely new XCode project files for Mac OSX which is now
279 capable to execute our autoconf environment, thus no need anymore
280 to maintain the compile time configuration file (osx/version.h) for
281 OSX manually (patch by Toshi Nagata)
282 - fixed buggy boolean --enable-foo / --disable-foo configure script
283 parameters
284 - global.h now only covers global definitions that are needed for the
285 C++ API header files, all implementation internal global definitions
286 are now in global_private.h
287 - atomic.h is not exposed to the C++ API anymore
288 - no need to include config.h anymore for using LS's API header files
289 - fixed warnings in API doc generation
290
291 * general changes:
292 - replaced the old, confusing MIDI program change mechanism by a
293 flexible MIDI instrument mapper which allows to map arbitrary
294 (MIDI bank, MIDI program) pairs with arbitrary
295 (engine type, instrument file, file index) triplets which will be
296 loaded on the respective channel when such MIDI program change
297 messages arrive, beside that, each entry allows to define a life-time
298 strategy for the instrument, so the user can define whether the
299 instrument should i.e. be permanently loaded (to be able to switch
300 quickly among sounds) or i.e. loaded just on demand when the
301 respective program change arrives (to safe RAM space), as well as a
302 global volume factor for each entry, so the user can adjust the volume
303 dynamic of his mapped instrument collection without having to modify
304 the instrument files, also one can manage arbitrary amount of such
305 MIDI instrument maps and assign each sampler channel individually
306 a certain map, so that i.e. separation of normal instruments and
307 drumkits is possible
308 - new notification events for tracking changes to audio/MIDI devices,
309 MIDI instrument maps, MIDI instruments, FX sends, global volume.
310 - sampler was limited to load max. 200 instruments in the background
311 due to a constant size RingBuffer FIFO which is now replaced by a
312 dynamic (unlimited) size std::list FIFO
313 - added FX sends, these allow to route audio signals to arbitrary audio
314 output channels for being processed by external effect processors
315 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
316 controllers
317 - global (sampler wide) volume can now be controlled at runtime
318 - Implemented new, improved notification system
319 - fixed compilation errors regarding OSX
320 (patch by Toshi Nagata)
321 - implemented instruments database
322 - added support for escape sequences to the instruments database
323 - added highly experimental support for on-the-fly instrument editing
324 within the sampler's process (by using instrument editor plugins),
325 you'll notice the new "Registered instrument editors:" message on
326 startup, added a new LSCP command:
327 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
328 to spawn a matching instrument editor for the instrument on the
329 given sampler channel, the plugin path can be overridden at compile
330 time with ./configure --enable-plugin-dir=/some/dir
331 - added experimental code for synchronizing instrument editors hosted
332 in the sampler's process to safely edit instruments while playing
333 without a crash (hopefully) by either suspending single regions
334 wherever possible or if unavoidable whole engine(s)
335 - fixed several issues in fundamental "Thread" class: set scheduling
336 policy and priority on thread level, set a minimum stack size for
337 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
338 threads simply inherited properties of starting thread instead of
339 setting their own policy and priority
340 - minor fix in our automatic stack trace mechanism on crashes, the
341 main process did not wait for the stack trace process to finish
342 its output
343 - fixed some minor memory leaks
344 - reenabled assembly features support, at the moment only for
345 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
346 - minor assembly fix in x86 features detection (don't use the PIC
347 register, to avoid relocations in the text segment at runtime)
348 - POSIX callback functions of Thread.h are hidden
349
350 * MIDI driver:
351 - dispatch bank select (MSB and LSB) messages
352
353 * audio driver:
354 - the ALSA audio output driver parameters now reflect the correct
355 parameter value ranges for the respective selected sound card
356 (patch by Till Wimmer, a bit fixed and extended)
357
358 * Gigasampler format engine:
359 - if a filter is used and EG2 finishes before EG1, let the voice
360 die when EG2 has finished (this fixes a problem with clicks and
361 voice starvation for some gigs)
362 - playback is no longer disabled during instrument loading
363 - all notes playing on a channel that changes its instrument keep
364 playing with the old instrument until they get a note off
365 command
366 - EG fix: a release value of zero could cause noises or crash
367 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
368 - EG fine tuning: when attack is zero the EG starts at a level
369 above max sustain level, which means that there is a decay phase
370 even if sustain is 100%
371 - more EG fixes: the level could sometimes go below zero and cause
372 noises or crashes
373 - minor fix of EGDecay (patch by Toshi Nagata)
374 - fixed compiler error when --enable-override-filter-type was
375 supplied to the configure script (fixes #46)
376 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
377 instead of a fix value
378 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
379 127 (solo mode) only kill voices if the respective mode really
380 changed
381
382 * LSCP server:
383 - fixed compile time error for old Bison versions
384 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
385 - parser now supports extended ASCII character set
386 (up to ASCII code 255, i.e. includes now umlauts and accents)
387 - filename arguments in LSCP commands now allow to use escape
388 sequences, that is directly literal as one of: \', \", \\, \n, \r,
389 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
390 code value like \xf2) (fixes bug #24)
391 - the following LSCP commands now also support escape sequences for at
392 least one of their text-based parameters (i.e. name, description):
393 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
394 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
395 "SET DB_INSTRUMENT_DIRECTORY NAME",
396 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
397 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
398 "FIND DB_INSTRUMENT_DIRECTORIES"
399 - returns verbose syntax errors (line and column where syntax error
400 occured, the unexpected character and the actually expected, possible
401 character(s), the latter only if less than 5 possibilities)
402 - made sure that LSCP syntax is not affected by gigedit locale
403 settings
404 - bugfix regarding strings parameter lists: all comma separated lists
405 of strings were treated as being one string containing commas
406 (fixes #57)
407
408 * Bug fixes:
409 - fixed crash occurring on certain LSCP scripts (Bug 39)
410 - another thread safety fix for lscp "load engine" and "set
411 channel audio output device"
412 - fixed a crash which occurs when reassigning the same engine
413 on a sampler channel with connected MIDI device
414 - fixed a crash which occurs when changing the number of ports of a MIDI
415 device connected to a sampler channel to number less then or equal
416 to the index of the port to which the sampler channel is connected.
417 - The previous bindings were not been disconnected when altering
418 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
419 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
420 - The active stream/voice count statistic was incorrect.
421 - notification events were not been sent for some sampler
422 channel changes
423 - added default min and max values to restrict the number of allowed
424 audio output channels and MIDI input ports
425 - the connection to the PCM interface is now closed when destroying
426 an audio output device
427 - files with slash in their path or filename could not be loaded
428
429 * test cases:
430 - updated and fixed (haven't been touched in a while)
431
432 Version 0.4.0 (24 November 2006)
433
434 * packaging changes:
435 - changed deprecated copyright attribute to license; added ldconfig
436 to post-(un)install steps; added devel package for liblinuxsampler;
437 to linuxsampler.spec (RPM)
438 - install necessary development header files for allowing 3rd party
439 applications to link against liblinuxsampler
440 - liblinuxsampler's API documentation can be generated with 'make docs'
441 (Doxygen required)
442 - added benchmark to automatically detect the best triangle LFO
443 implementation (currently either an integer math solution or a
444 di-harmonic approximation), automatic detection can be overriden
445 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
446 configure script argument though (mandatory for cross-compilation)
447 - do not automatically pick optimized gcc flags if the user already
448 provided some on his own (as CXXFLAGS)
449 - added compile time option to disable processing of All-Notes-Off MIDI
450 messages
451 - added compile time options to allow disabling the various audio and
452 MIDI drivers
453 - fixed automatic GCC CPU switch detection on PPC
454 (patch by Ebrahim Mayat)
455
456 * Gigasampler format engine:
457 - extensive synthesis optimization
458 (reimplementation of EGs and LFO(s), removed synthesis parameter
459 prerendering and the synthesis parameter matrix in general, splitting
460 each audio fragment into subfragments now where each subfragment uses
461 constant pitch and filter coefficients. The volume coefficient is
462 linearly interpolated inside a subfragment, unless
463 --disable-interpolate-volume is set.)
464 - fine tuning of the EG modulation parameters
465 - improved filter cutoff calculation by adding support for the
466 following gig parameters: Cutoff freq (used when no cutoff
467 controller is defined), Control invert, Minimum cutoff, Velocity
468 curve and Velocity range. The keyboard tracking now scales
469 cutoff frequency instead of resonance.
470 - added support for gig parameter Resonance.
471 - fixed bug in sysex handling (patch by Juan Linietsky)
472 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
473 which can be overridden with --enable-global-attenuation
474 - EG fixes: made the length of "attack hold" stage more
475 accurate. Release stage can now start before attack stage
476 ends. Cancel release didn't work when sustain was zero. Attack
477 time now has a minimal value to prevent clicks.
478 - fixed pitch changes larger than one octave
479 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
480 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
481 all modes can be altered via standard GM messages, that is CC5 for
482 altering portamento time, CC65 for enabling / disabling portamento
483 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
484 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
485 parameter) and crossfade
486 - added support for the "attenuation controller threshold" gig
487 parameter
488 - added smoothing of volume changes caused by control change
489 messages
490 - sample loop parameters are now taken from the DimensionRegion
491 instead of the wave chunk
492 - fixed keyswitching for v3 gigs with a number of keyswitch splits
493 not equal to a power of two
494 - reimplementation of the filter algorithm. The new filter is more
495 accurate and supports all gig filter types, including bandreject
496 and lowpass turbo.
497 - real support for 24 bit samples - samples are not truncated to
498 16 bits anymore
499 - support for aftertouch (channel pressure, not polyphonic
500 aftertouch)
501 - LFO1 behaviour fixed (dampening from max volume instead of
502 amplifying from 0)
503
504 * LSCP server:
505 - fixed application exit on broken pipe error (fixes bug #20)
506 - fixed the notification messages delay due to lack of
507 network activity (fixes bug #26)
508 - fixed parser bug which occured on space(s) within device parameters
509 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
510
511 * audio driver:
512 - added aRts audio output driver (by no means RT safe)
513
514 * MIDI driver:
515 - fixed legacy sysex code which caused dispatching of MIDI SysEx
516 messages several times instead of once
517 - API extension for MIDI drivers which already supply exact time stamps
518 for events (i.e. for offline rendering based MIDI drivers)
519 - added checks for bad MIDI data
520
521 * linuxsampler application:
522 - show available sampler engine types on startup
523
524 * general changes:
525 - support for muting sampler channels and solo mode of the same, two new
526 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
527 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
528 introduced for this, the behavior is the same like on a mixer console
529 (patch by Grigor Iliev, a bit adjusted). Also added configure option
530 --enable-process-muted-channels which can be used to enable the
531 processing of muted channels.
532 - support for sostenuto pedal
533 - support for monitoring the total number of active voices
534 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
535 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
536 - fixed some memory management errors
537 - fixed some concurrency problems that could lead to crashes when
538 LSCP commands were executed
539 - fixed crash when instrument loading failed previously on the same
540 sampler channel (fixes bug #36)
541
542 Version 0.3.3 (15 July 2005)
543
544 * packaging changes:
545 - fixed compilation with gcc 4.0
546
547 * Gigasampler format engine:
548 - LFO preprocessing was performed even though the respective LFO was
549 disabled by the instrument patch (minor efficiency fix)
550 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
551 for volume ramp downs in the same fragment (needed for current voice
552 stealing implementation) then simply inform the user with a warning
553 about possible click sounds and reduce the volume ramp down
554 appropriately instead of cancelling the audio device connection
555
556 Version 0.3.2 (24 June 2005)
557
558 * packaging changes:
559 - updated autotools build files to compile on OS X
560 (conditional compilation of CoreMIDI and MidiShare drivers)
561 - hand-crafted assembly optimization code can be disabled with
562 './configure --disable-asm' (definitely not recommended)
563 - fixed 'make dist' rule to include all necessary files
564 - require automake (>= 1.5) for 'make -f Makefile.cvs'
565 (due to 'dist-bzip2' automake option)
566
567 * Gigasampler format engine:
568 - support for the gig parameters for "release velocity response" curves
569 - fine tuning of the EGADSR envelope
570 - volume of release triggered samples now depends on note-on velocity,
571 note length and gig parameter "release trigger decay" instead of
572 note-off velocity.
573 - revised voice stealing
574 (fixes crash and endless loop caused by voice stealing)
575 - don't reset scale tuning on instrument or audio output device change
576 - handle key group conflicts right at the beginning of each fragment
577 instead of when the respective voice is actually launched
578 (fixes undefined behavior if stolen voices belonged to a key group -
579 this case was followed by a "killed voice survived" error message)
580 - fixed minor issue with null/silence samples
581 (those stole voices even though they don't need a voice at all which
582 resulted in "voice stealing didn't work out" messages)
583 - don't reset volume, pan, pitch and MIDI controller values on
584 instrument or audio output device change
585
586 * LSCP server:
587 - fixed some crashes (patch by Grigor Iliev, fixes #19)
588 - fixed LSCP event "CHANNEL_INFO" notification
589 (e.g. did not notify on volume changes or MIDI program change events)
590
591 * linuxsampler application:
592 - added command line parameters --lscp-addr and --lscp-port to override
593 default IP address and port of LSCP server
594
595 Version 0.3.1 (24 May 2005)
596
597 * initial release
