File size: 30219 byte(s)
* fixed crash happening when a pitch bend event arrived at the same
  time a new instrument was loading
* fixed building with sqlite installed in a non-standard directory

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