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

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

36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to

127 * Host plugins:
128 - AU bugfix: failed to destroy its audio/MIDI devices
129 - Listen to all interfaces on Mac OS X (INADDR_ANY)
130 - VST bugfix: If the host called resume() before and after
131 changing sample rate or block size, the number of channels was
132 incorrectly set to two. This caused silence in Cubase 5.
133 - save engine type (gig, sfz or sf2) in plugin state
134 - VST: when opening Fantasia, look for both 32 and 64 bit Java on

140 specified
142 * MIDI driver:
143 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
144 the ALSA sequencer client name
145 - removed limit of maximum amount of MIDI ports per MIDI device, since
146 there is no reason for this limit
148 * audio driver:

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