Revision 1928 - (show annotations) (download)
Fri Jul 3 11:14:46 2009 UTC (10 years, 5 months ago) by schoenebeck
File size: 30387 byte(s)
* VST: look for the Fantasia binary in liblinuxsampler.dll's directory and
  in its parent directory (required for the next Windows installer which
  allows to install the 64 bit and 32 bit version of LinuxSampler VST
  alongside)

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