File size: 30670 byte(s)
* when cross-compiling, don't try to create instruments.db
* fix for new mingw-w64 version, which has usleep

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