20 - Mac OS X: Makefile fix for the install-strip target
22 * general changes:
23 - Refactoring: moved the independent code from

143 - Listen to all interfaces on Mac OS X (INADDR_ANY)
144 - VST bugfix: If the host called resume() before and after
145 changing sample rate or block size, the number of channels was
146 incorrectly set to two. This caused silence in Cubase 5.
147 - save engine type (gig, sfz or sf2) in plugin state
148 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
149 64 bit Windows

154 specified
156 * MIDI driver:
157 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
158 the ALSA sequencer client name
159 - removed limit of maximum amount of MIDI ports per MIDI device, since
160 there is no reason for this limit
162 * audio driver:

202 * Bug fixes:
203 - Fixed crash which may occur when MIDI key + transpose is out of range
204 - minor valgrind fixes
205 - fixed crash which occurred when changing an already deployed sampler
206 channel to a different engine type
207 - fixed crash when deleting a sampler channel or changing engine
208 type while an instrument load was in progress
209 - bugfix: playing a note while changing the instrument could cause
210 a crash, or give "Handing back unknown region" error messages
211 - bugfix: calling SET VOICES (which Fantasia does on start and
212 refresh) could cause instruments to be unloaded
213 - Mac OS X: fixed name collision of enum in EffectControl and
214 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
215 - Mac OS X: fixed hanging threads
216 - Windows: disabled the previous thread fix on non-Mac systems, as
217 it caused hanging threads on Windows

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