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

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

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

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