  the demands of the new engines for flexible signal processing.
* sf2: Initial implementation of vibrato LFO, fixes in modulation EG and
  and volume EG (work in progress)

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20
21 * general changes:
22 - Refactoring: moved the independent code from
23 the Gigasampler format engine to base classes
24 - command line option '--profile' is currently disabled, since the
25 respective profiling code is currently broken
26 - Introduced support for optional environment variable
27 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
28 where the sampler shall look for instrument editor plugins
29 (patch by Luis Garrido, slightly modified).
30 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
31 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
32 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
33 note (in this implementation of the sampler its simply hard routed to
34 the 1st effect send of the sampler channel, no matter what the actual
35 effect type is)
36 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
37 note (in this implementation of the sampler its simply hard routed to
38 the 2nd effect send of the sampler channel, no matter what the actual
39 effect type is)
40 - implemented support for internal LADSPA effects
41 - raised limit of program change queue from 100 to 512
42 (as suggested by Alex Stone)
43
44 * Gigasampler format engine:
45 - implemented the "round robin keyboard" dimension
46 - fixed round robin and random dimensions for cases when number of
47 dimension zones is not a power of two

58 - allow non-numerical key values ("C#4" for example)
59 - "key" opcode now sets pitch_keycenter too
60 - fixed error when unloading instrument with same sample used by
61 multiple regions

87 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
88 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
89 cutoff_cc, cutoff_chanaft.
90 - bugfix: zero ampeg_sustain didn't work
91 - added support for velocity effect on amplifier envelope time
92 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

109 * Host plugins:
110 - AU bugfix: failed to destroy its audio/MIDI devices
111 - Listen to all interfaces on Mac OS X (INADDR_ANY)
112 - VST bugfix: If the host called resume() before and after
113 changing sample rate or block size, the number of channels was

119 stereo
120 - VST: made it possible to build the VST plugin for Mac
121 - AU: link AU plugin dynamically if --disable-shared isn't
122 specified
123
124 * MIDI driver:
125 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
126 the ALSA sequencer client name
127 - removed limit of maximum amount of MIDI ports per MIDI device, since
128 there is no reason for this limit
129

169
170 * Bug fixes:
171 - Fixed crash which may occur when MIDI key + transpose is out of range
172 - minor valgrind fixes
173 - fixed crash which occurred when changing an already deployed sampler
174 channel to a different engine type
175 - fixed crash when deleting a sampler channel or changing engine
176 type while an instrument load was in progress
177 - bugfix: playing a note while changing the instrument could cause
178 a crash, or give "Handing back unknown region" error messages
179 - bugfix: calling SET VOICES (which Fantasia does on start and
180 refresh) could cause instruments to be unloaded
181 - Mac OS X: fixed name collision of enum in EffectControl and
182 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
183 - Mac OS X: fixed hanging threads
184 - Windows: disabled the previous thread fix on non-Mac systems, as
185 it caused hanging threads on Windows
186 - Fixed possible crashes due to corrupted MIDI/audio device list
187 after MIDI/audio device creation failure
188
189 Version 1.0.0 (31 July 2009)
190
191 * packaging changes:
192 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
193 causing e.g. the libgig test to fail when
194 "./configure --disable-jack-driver" was used
195 (patch by Alexis Ballier)
196 - fixed compilation with gcc 4.3
197 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
198 - fixed configure so it detects x86_64 (#107)
199 - fixes for building with newer MinGW versions
200 - fix for building with bison 2.4 (#111)
201 - fixed building with libgig installed in a non-standard directory
202 - minor fix in configure for mmsystem.h detection on MinGW
203 - Windows: look for editor plugins and Fantasia using base
204 directory of liblinuxsampler dll (look in the same directory and one
205 directory above)
206 - configure script fix: removed unconditional use of SSE
207 - fixed building with sqlite installed in a non-standard directory
208 - when cross-compiling, don't try to create instruments.db
209 - fix for new mingw-w64 version, which has usleep
210
211 * general changes:
212 - bugfix: on some POSIX systems instrument editor plugins refused to
213 load as we used a non-portable Linux specific struct field
214 (fixes bug #70, patch by Ronald Baljeu)
215 - fixed endless loop which occured when loading an instrument editor
216 plugin DLL on Windows systems failed
217 - fixed memory leaks that occurred when liblinuxsampler was unloaded
218 - optimized the SynchronizedConfig class so it doesn't wait
219 unnecessarily long after an update
220 - added support for notifying instrument editors on note-on / note-off
221 events (e.g. to highlight the pressed keys on the virtual keyboard
222 of gigedit)
223 - added support for triggering notes by instrument editors (see above)
224 - be verbose on DLL load errors (on Linux)
225 - fixed di-harmonic triangle LFO implementation (this LFO implementation
226 is only used by very few systems, most pick the int math
227 implementation, which is usually faster)
228 - fixes for audio drivers with varying buffer sizes
229 - experimental support for running LinuxSampler as a DSSI, LV2 and
230 VST plugin
231 - notification events for stream/voice count statistics are now sent
232 only when there are actual changes
233 - added memory ordering constraints to improve stability on
234 multi-core and multi-cpu systems
235 - maximum voices and disk streams can now be altered at runtime
236 - fixed CPU feature detection on x86_64 (maybe fixes #108)
237 - automatic stacktrace mechanism is now turned off by default and can
238 be switched on by command line option "--stacktrace" (the automatic
239 stacktrace mechanism seems to be broken on most systems at the moment)
240 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
241 a pointer to the launched InstrumentEditor object
242 - added optional 3rd party user data parameter for following
243 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
244 InstrumentEditor::Launch(),
245 InstrumentManager::LaunchInstrumentEditor()
246 - theoretical fix: made SynchronizedConfig follow C++0x memory
247 model more strictly
248 - fixes for using large audio device buffers
249 - Windows: add the installation directory to the DLL search path
250 when loading an editor plugin (solves problems with VST and
251 gigedit on systems with other GTK versions installed)
252
253 * audio driver:
254 - removed the nonsense audio channel constraint (which was hard coded to
255 max. 100 audio channels) for most audio drivers
256 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
257 opposed to the LSCP specs
258 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
259 reflected the wrong value
260 - fixed a memory management bug in ASIO driver
261 - Makefile fix: JACK_CFLAGS wasn't used
262 - JACK: use jack_client_open instead of the deprecated
263 jack_client_new
264 - added (experimental) CoreAudio driver
265 - applied old fixes to the ASIO driver that were included in the
266 previous binary release but accidentally never committed to CVS
267 (fixes #117)
268 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
269 win64)
270 - VST: added support for sample rate and buffer size changes
271 - VST: close editor (Fantasia) when the VST is removed
272 - VST: avoid opening Fantasia more than once for each VST instance
273 - VST: export main function as "main" on Linux too (fix for
274 energyXT)
275 - VST: changed number of output channels from one stereo to 16
276 stereo
277 - added channel routing, fxsends and midi maps to the settings
278 stored in the plugin state
279 - performance optimization of AudioChannel::MixTo() and
280 AudioChannel::CopyTo() methods using GCC vector exensions
281 (if available)
282 - ASIO fixes: avoid initializing the device twice, avoid throwing
283 exception when getting parameters from a disconnected device
284
285 * MIDI driver:
286 - added JACK MIDI driver
287 - dispatch bank select as ordinary CC as well, the user might seriously
288 want to (mis)use it for some purpose ("fixed" in all current MIDI
289 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
290 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
291 CoreMidi or AU
292 - fixed mingw-w64 compilation error in MME driver
293 - made program change handling in MIDI thread real-time safe by
294 moving the logic to a non-RT thread
295 - fixed minor memory leak in ALSA driver
296
297 * instruments database:
298 - avoid time consuming samples scanning when adding instruments
299 to the instruments database
300 - added support for handling lost files in the instruments database
301 - Implemented option for adding instruments in separate directories
302 in the instruments database
303 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
304 - work-around for missing fnmatch function on Windows to make
305 instrument database compilable
306 - added instrument database support on Windows
307 works with both standalone mode and VST plugin.
308 the instruments DB file is located in
309 %USERPROFILE%\.linuxsampler\instruments.db which allows different
310 databases for each windows user
311 if no DB is present it automatically creates the .linuxsampler subdir
312 and then creates an empty DB
313 - fixed recursive import, which was broken on Windows
314
315 * Gigasampler format engine:
316 - fixed a memory leak that could happen when a channel was deleted
317 while notes were playing
318 - made it possible to load an instrument even if the audio thread
319 isn't running
320 - added partial support for the "Controller Triggered" MIDI rule,
321 enough for piano gigs with pedal noise samples
322 - minor fix: only mark FX sends as being modified if really the
323 respective FX send MIDI controller was used
324 - added support for GM global device volume SysEx message
325 (can be selected at compile time to either apply globally to the
326 whole sampler [default] or only to the sampler channels that are
327 connected to the respective MIDI input port the SysEx message arrived
328 on)
329 - bugfix: notes triggered at position 0 in the audio buffer were
330 sometimes wrongly killed in the same buffer, causing no sound to
331 be played
332 - added support for chromatic / drumkit mode Roland GS Sysex message
333 which is usally used to switch a part between chromatic sounds and
334 drumkit sounds (as opposed to their common default setting of MIDI
335 part 10 being a drumkit part and all other ones chromatic parts), in
336 LS however one can switch between the first 16 MIDI instrument maps
337 defined for the sampler
338 - made it possible to create multiple sample channels even if the
339 audio thread isn't running
340 - fixed crash when removing channel with active voices (#116)
341 - bugfix: on sample reference changes (instrument editor), only
342 un-cache the respective sample if it's really not used by any
343 sampler engine anymore
344 - re-cache samples in case they were changed by an instrument editor,
345 e.g. when a sample was added while playing (#82)
346 - fixed hanging notes which occured when note-off event had the exact
347 same time stamp as the voice's note-on event and occured both in the
348 same audio fragment cycle (fixes bug #112)
349 - added support for the "fine tune" and "pitch bend range"
350 instrument-level gig parameters
351 - fixed minor artifacts in pitch bend handling
352 - added support for GS Reset SysEx message
353 - allow gig files to use unlimited downward pitch shifting
354 - added a limit check for upward pitch shifting
355 - bugfix: sometimes, when playing a note twice fast, the second
356 note was silent
357 - fixed crash happening when a pitch bend event arrived at the
358 same time a new instrument was loading
359
360 * LSCP server:
361 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
362 react on MIDI data arriving on certain sampler channels (so far only
363 Note-On and Note-Off events are sent via this LSCP event)
364 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
365 react on MIDI data arriving on certain MIDI input devices (so far only
366 Note-On and Note-Off events are sent via this LSCP event)
367 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
368 SET DB_INSTRUMENT FILE_PATH
369 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
370 frontends to send MIDI messages to specific sampler channel
371 - added two additional fields to GET FILE INSTRUMENT INFO command -
372 KEY_BINDINGS and KEYSWITCH_BINDINGS
373 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
374 was incorrect
375 - Optimized the retrieval of the MIDI instrument mappings
376 - added new LSCP command "SET VOICES" to globally alter the maximum
377 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
378 be triggered respectively
379 - added new LSCP command "SET STREAMS" to globally alter the maximum
380 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
381 which will be triggered respectively
382 - bugfix: retry if "select" returns EINTR (this fixes a crash when
383 a gigedit file dialog is opened)
384 - close all connections when LSCPServer is deleted
385 - hard close of all sockets on exit
386 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
387 driver
388
389 * Bug fixes:
390 - fixed a crash which occurs when removing a sampler channel waiting
391 to start instrument loading after another channel
392 - fixed a crash which occurs when removing a sampler channel with
393 instrument loading in progress (bug #113)
394 - fixed termination caused by uncaught exception when adding MIDI
395 instrument with PERSISTENT load mode
396 - fixed possible iterator invalidations when resetting the sampler
397 - fixed memory leaks when issuing the following LSCP commands:
398 GET AUDIO_OUTPUT_DRIVER INFO
399 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
400 GET MIDI_INPUT_DRIVER INFO
401 GET MIDI_INPUT_DRIVER_PARAMETER INFO
402 - fixed possible compilation error when sqlite is not present
403 - fixed orphaned pointers when setting maximum voices limit (bug #118)
404 - fixed crash when changing the audio output device of a sampler
405 channel with loaded instrument and start playing notes
406 - fixed endless loop in Engine::SuspendAll() (bug #120)
407 - fixed a low-level atomic load function that was broken on 64-bit
408 PowerPC, which probably could cause crashes on that platform
409 - fixed a memory management error which could cause a crash when a
410 plugin was unloaded
411 - bugfix: two private structs had the same name, which could cause
412 problems if the linker chose the wrong constructor
413 - fixed low-level ConditionServer usage bug that caused lockups on
414 Windows
415
416
417 Version 0.5.1 (6 December 2007)
418
419 * packaging changes:
420 - added autoconf checks for pthread library
421 - added autoconf check for pthread bug found on certain NPTL-enabled
422 glibc versions (see Gentoo bug report #194076)
423 - added autoconf checks for MS Windows
424
425 * general changes:
426 - bugfix: the thread used by an editor plugin didn't die when the
427 editor closed
428 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
429 out all the space. operator--() did not apply size_mask after
430 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
431 order to avoid problems with the _NonVolatileReader functions.
432 - bugfix: Stream.h: added a missing divide by BytesPerSample in
433 GetWriteSpace(). Since this function is currently only used in
434 the stream's qsort() compare function, it didn't trigger any
435 bugs.
436 - Resampler.h, Synthesizer.h: cubic interpolation now works in
437 24bit mode too. Faster method to read 24bit words on little
438 endian machines (x86): replaced 3 byte reads + shifts with a 1
439 unaligned 32bit read and shift
440 - experimental support for MS Windows (MIDI input via MME, AUDIO
441 output via ASIO)
442 - made handling of SIGINT signal (Ctrl-C) a bit more robust
443 - support for monitoring the total number of active disk streams
444 (new LSCP commands: GET TOTAL_STREAM_COUNT,
445 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
446
447 * AUDIO driver:
448 - added Windows ASIO low latency audio driver
449
450 * MIDI driver:
451 - added MME Windows MIDI driver
452
453 * LSCP server:
454 - added support for Windows style path / filenames, however with
455 forward slash path separators instead of backslash
456 (i.e. "C:/foo/bar.gig")
457 - allow naughty liblscp to send non-string device parameters within
458 apostrophes as well
459 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
460 "LIST FILE INSTRUMENTS <file>" and
461 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
462 about an arbitrary instrument file on the system where the sampler is
463 running on
464
465 Version 0.5.0 (15 October 2007)
466
467 * packaging changes:
468 - config.h is not going to be installed along with liblinuxsampler's
469 API header files anymore
470 - only the API relevant header (and source) files will be exported to
471 the Doxygen API documentation (explicitly listed in Doxyfile.in)
472 - added completely new XCode project files for Mac OSX which is now
473 capable to execute our autoconf environment, thus no need anymore
474 to maintain the compile time configuration file (osx/version.h) for
475 OSX manually (patch by Toshi Nagata)
476 - fixed buggy boolean --enable-foo / --disable-foo configure script
477 parameters
478 - global.h now only covers global definitions that are needed for the
479 C++ API header files, all implementation internal global definitions
480 are now in global_private.h
481 - atomic.h is not exposed to the C++ API anymore
482 - no need to include config.h anymore for using LS's API header files
483 - fixed warnings in API doc generation
484
485 * general changes:
486 - replaced the old, confusing MIDI program change mechanism by a
487 flexible MIDI instrument mapper which allows to map arbitrary
488 (MIDI bank, MIDI program) pairs with arbitrary
489 (engine type, instrument file, file index) triplets which will be
490 loaded on the respective channel when such MIDI program change
491 messages arrive, beside that, each entry allows to define a life-time
492 strategy for the instrument, so the user can define whether the
493 instrument should i.e. be permanently loaded (to be able to switch
494 quickly among sounds) or i.e. loaded just on demand when the
495 respective program change arrives (to safe RAM space), as well as a
496 global volume factor for each entry, so the user can adjust the volume
497 dynamic of his mapped instrument collection without having to modify
498 the instrument files, also one can manage arbitrary amount of such
499 MIDI instrument maps and assign each sampler channel individually
500 a certain map, so that i.e. separation of normal instruments and
501 drumkits is possible
502 - new notification events for tracking changes to audio/MIDI devices,
503 MIDI instrument maps, MIDI instruments, FX sends, global volume.
504 - sampler was limited to load max. 200 instruments in the background
505 due to a constant size RingBuffer FIFO which is now replaced by a
506 dynamic (unlimited) size std::list FIFO
507 - added FX sends, these allow to route audio signals to arbitrary audio
508 output channels for being processed by external effect processors
509 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
510 controllers
511 - global (sampler wide) volume can now be controlled at runtime
512 - Implemented new, improved notification system
513 - fixed compilation errors regarding OSX
514 (patch by Toshi Nagata)
515 - implemented instruments database
516 - added support for escape sequences to the instruments database
517 - added highly experimental support for on-the-fly instrument editing
518 within the sampler's process (by using instrument editor plugins),
519 you'll notice the new "Registered instrument editors:" message on
520 startup, added a new LSCP command:
521 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
522 to spawn a matching instrument editor for the instrument on the
523 given sampler channel, the plugin path can be overridden at compile
524 time with ./configure --enable-plugin-dir=/some/dir
525 - added experimental code for synchronizing instrument editors hosted
526 in the sampler's process to safely edit instruments while playing
527 without a crash (hopefully) by either suspending single regions
528 wherever possible or if unavoidable whole engine(s)
529 - fixed several issues in fundamental "Thread" class: set scheduling
530 policy and priority on thread level, set a minimum stack size for
531 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
532 threads simply inherited properties of starting thread instead of
533 setting their own policy and priority
534 - minor fix in our automatic stack trace mechanism on crashes, the
535 main process did not wait for the stack trace process to finish
536 its output
537 - fixed some minor memory leaks
538 - reenabled assembly features support, at the moment only for
539 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
540 - minor assembly fix in x86 features detection (don't use the PIC
541 register, to avoid relocations in the text segment at runtime)
542 - POSIX callback functions of Thread.h are hidden
543
544 * MIDI driver:
545 - dispatch bank select (MSB and LSB) messages
546
547 * audio driver:
548 - the ALSA audio output driver parameters now reflect the correct
549 parameter value ranges for the respective selected sound card
550 (patch by Till Wimmer, a bit fixed and extended)
551
552 * Gigasampler format engine:
553 - if a filter is used and EG2 finishes before EG1, let the voice
554 die when EG2 has finished (this fixes a problem with clicks and
555 voice starvation for some gigs)
556 - playback is no longer disabled during instrument loading
557 - all notes playing on a channel that changes its instrument keep
558 playing with the old instrument until they get a note off
559 command
560 - EG fix: a release value of zero could cause noises or crash
561 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
562 - EG fine tuning: when attack is zero the EG starts at a level
563 above max sustain level, which means that there is a decay phase
564 even if sustain is 100%
565 - more EG fixes: the level could sometimes go below zero and cause
566 noises or crashes
567 - minor fix of EGDecay (patch by Toshi Nagata)
568 - fixed compiler error when --enable-override-filter-type was
569 supplied to the configure script (fixes #46)
570 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
571 instead of a fix value
572 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
573 127 (solo mode) only kill voices if the respective mode really
574 changed
575
576 * LSCP server:
577 - fixed compile time error for old Bison versions
578 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
579 - parser now supports extended ASCII character set
580 (up to ASCII code 255, i.e. includes now umlauts and accents)
581 - filename arguments in LSCP commands now allow to use escape
582 sequences, that is directly literal as one of: \', \", \\, \n, \r,
583 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
584 code value like \xf2) (fixes bug #24)
585 - the following LSCP commands now also support escape sequences for at
586 least one of their text-based parameters (i.e. name, description):
587 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
588 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
589 "SET DB_INSTRUMENT_DIRECTORY NAME",
590 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
591 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
592 "FIND DB_INSTRUMENT_DIRECTORIES"
593 - returns verbose syntax errors (line and column where syntax error
594 occured, the unexpected character and the actually expected, possible
595 character(s), the latter only if less than 5 possibilities)
596 - made sure that LSCP syntax is not affected by gigedit locale
597 settings
598 - bugfix regarding strings parameter lists: all comma separated lists
599 of strings were treated as being one string containing commas
600 (fixes #57)
601
602 * Bug fixes:
603 - fixed crash occurring on certain LSCP scripts (Bug 39)
604 - another thread safety fix for lscp "load engine" and "set
605 channel audio output device"
606 - fixed a crash which occurs when reassigning the same engine
607 on a sampler channel with connected MIDI device
608 - fixed a crash which occurs when changing the number of ports of a MIDI
609 device connected to a sampler channel to number less then or equal
610 to the index of the port to which the sampler channel is connected.
611 - The previous bindings were not been disconnected when altering
612 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
613 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
614 - The active stream/voice count statistic was incorrect.
615 - notification events were not been sent for some sampler
616 channel changes
617 - added default min and max values to restrict the number of allowed
618 audio output channels and MIDI input ports
619 - the connection to the PCM interface is now closed when destroying
620 an audio output device
621 - files with slash in their path or filename could not be loaded
622
623 * test cases:
624 - updated and fixed (haven't been touched in a while)
625
626 Version 0.4.0 (24 November 2006)
627
628 * packaging changes:
629 - changed deprecated copyright attribute to license; added ldconfig
630 to post-(un)install steps; added devel package for liblinuxsampler;
631 to linuxsampler.spec (RPM)
632 - install necessary development header files for allowing 3rd party
633 applications to link against liblinuxsampler
634 - liblinuxsampler's API documentation can be generated with 'make docs'
635 (Doxygen required)
636 - added benchmark to automatically detect the best triangle LFO
637 implementation (currently either an integer math solution or a
638 di-harmonic approximation), automatic detection can be overriden
639 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
640 configure script argument though (mandatory for cross-compilation)
641 - do not automatically pick optimized gcc flags if the user already
642 provided some on his own (as CXXFLAGS)
643 - added compile time option to disable processing of All-Notes-Off MIDI
644 messages
645 - added compile time options to allow disabling the various audio and
646 MIDI drivers
647 - fixed automatic GCC CPU switch detection on PPC
648 (patch by Ebrahim Mayat)
649
650 * Gigasampler format engine:
651 - extensive synthesis optimization
652 (reimplementation of EGs and LFO(s), removed synthesis parameter
653 prerendering and the synthesis parameter matrix in general, splitting
654 each audio fragment into subfragments now where each subfragment uses
655 constant pitch and filter coefficients. The volume coefficient is
656 linearly interpolated inside a subfragment, unless
657 --disable-interpolate-volume is set.)
658 - fine tuning of the EG modulation parameters
659 - improved filter cutoff calculation by adding support for the
660 following gig parameters: Cutoff freq (used when no cutoff
661 controller is defined), Control invert, Minimum cutoff, Velocity
662 curve and Velocity range. The keyboard tracking now scales
663 cutoff frequency instead of resonance.
664 - added support for gig parameter Resonance.
665 - fixed bug in sysex handling (patch by Juan Linietsky)
666 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
667 which can be overridden with --enable-global-attenuation
668 - EG fixes: made the length of "attack hold" stage more
669 accurate. Release stage can now start before attack stage
670 ends. Cancel release didn't work when sustain was zero. Attack
671 time now has a minimal value to prevent clicks.
672 - fixed pitch changes larger than one octave
673 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
674 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
675 all modes can be altered via standard GM messages, that is CC5 for
676 altering portamento time, CC65 for enabling / disabling portamento
677 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
678 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
679 parameter) and crossfade
680 - added support for the "attenuation controller threshold" gig
681 parameter
682 - added smoothing of volume changes caused by control change
683 messages
684 - sample loop parameters are now taken from the DimensionRegion
685 instead of the wave chunk
686 - fixed keyswitching for v3 gigs with a number of keyswitch splits
687 not equal to a power of two
688 - reimplementation of the filter algorithm. The new filter is more
689 accurate and supports all gig filter types, including bandreject
690 and lowpass turbo.
691 - real support for 24 bit samples - samples are not truncated to
692 16 bits anymore
693 - support for aftertouch (channel pressure, not polyphonic
694 aftertouch)
695 - LFO1 behaviour fixed (dampening from max volume instead of
696 amplifying from 0)
697
698 * LSCP server:
699 - fixed application exit on broken pipe error (fixes bug #20)
700 - fixed the notification messages delay due to lack of
701 network activity (fixes bug #26)
702 - fixed parser bug which occured on space(s) within device parameters
703 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
704
705 * audio driver:
706 - added aRts audio output driver (by no means RT safe)
707
708 * MIDI driver:
709 - fixed legacy sysex code which caused dispatching of MIDI SysEx
710 messages several times instead of once
711 - API extension for MIDI drivers which already supply exact time stamps
712 for events (i.e. for offline rendering based MIDI drivers)
713 - added checks for bad MIDI data
714
715 * linuxsampler application:
716 - show available sampler engine types on startup
717
718 * general changes:
719 - support for muting sampler channels and solo mode of the same, two new
720 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
721 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
722 introduced for this, the behavior is the same like on a mixer console
723 (patch by Grigor Iliev, a bit adjusted). Also added configure option
724 --enable-process-muted-channels which can be used to enable the
725 processing of muted channels.
726 - support for sostenuto pedal
727 - support for monitoring the total number of active voices
728 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
729 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
730 - fixed some memory management errors
731 - fixed some concurrency problems that could lead to crashes when
732 LSCP commands were executed
733 - fixed crash when instrument loading failed previously on the same
734 sampler channel (fixes bug #36)
735
736 Version 0.3.3 (15 July 2005)
737
738 * packaging changes:
739 - fixed compilation with gcc 4.0
740
741 * Gigasampler format engine:
742 - LFO preprocessing was performed even though the respective LFO was
743 disabled by the instrument patch (minor efficiency fix)
744 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
745 for volume ramp downs in the same fragment (needed for current voice
746 stealing implementation) then simply inform the user with a warning
747 about possible click sounds and reduce the volume ramp down
748 appropriately instead of cancelling the audio device connection
749
750 Version 0.3.2 (24 June 2005)
751
752 * packaging changes:
753 - updated autotools build files to compile on OS X
754 (conditional compilation of CoreMIDI and MidiShare drivers)
755 - hand-crafted assembly optimization code can be disabled with
756 './configure --disable-asm' (definitely not recommended)
757 - fixed 'make dist' rule to include all necessary files
758 - require automake (>= 1.5) for 'make -f Makefile.cvs'
759 (due to 'dist-bzip2' automake option)
760
761 * Gigasampler format engine:
762 - support for the gig parameters for "release velocity response" curves
763 - fine tuning of the EGADSR envelope
764 - volume of release triggered samples now depends on note-on velocity,
765 note length and gig parameter "release trigger decay" instead of
766 note-off velocity.
767 - revised voice stealing
768 (fixes crash and endless loop caused by voice stealing)
769 - don't reset scale tuning on instrument or audio output device change
770 - handle key group conflicts right at the beginning of each fragment
771 instead of when the respective voice is actually launched
772 (fixes undefined behavior if stolen voices belonged to a key group -
773 this case was followed by a "killed voice survived" error message)
774 - fixed minor issue with null/silence samples
775 (those stole voices even though they don't need a voice at all which
776 resulted in "voice stealing didn't work out" messages)
777 - don't reset volume, pan, pitch and MIDI controller values on
778 instrument or audio output device change
779
780 * LSCP server:
781 - fixed some crashes (patch by Grigor Iliev, fixes #19)
782 - fixed LSCP event "CHANNEL_INFO" notification
783 (e.g. did not notify on volume changes or MIDI program change events)
784
785 * linuxsampler application:
786 - added command line parameters --lscp-addr and --lscp-port to override
787 default IP address and port of LSCP server
788
789 Version 0.3.1 (24 May 2005)
790
791 * initial release
