3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
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 - Mac OS X: Makefile fix for the install-strip target
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken

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
39 the 2nd effect send of the sampler channel, no matter what the actual

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

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

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