1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
21
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

29 where the sampler shall look for instrument editor plugins
30 (patch by Luis Garrido, slightly modified).
31 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34 note (in this implementation of the sampler its simply hard routed to
35 the 1st effect send of the sampler channel, no matter what the actual
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

147 * MIDI driver:
148 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
149 the ALSA sequencer client name

195 - minor valgrind fixes
196 - fixed crash which occurred when changing an already deployed sampler
197 channel to a different engine type
198 - fixed crash when deleting a sampler channel or changing engine
199 type while an instrument load was in progress
200 - bugfix: playing a note while changing the instrument could cause
201 a crash, or give "Handing back unknown region" error messages
202 - bugfix: calling SET VOICES (which Fantasia does on start and
203 refresh) could cause instruments to be unloaded
204 - Mac OS X: fixed name collision of enum in EffectControl and

211
212 Version 1.0.0 (31 July 2009)
213
214 * packaging changes:
215 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
216 causing e.g. the libgig test to fail when
217 "./configure --disable-jack-driver" was used
218 (patch by Alexis Ballier)
219 - fixed compilation with gcc 4.3
220 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
221 - fixed configure so it detects x86_64 (#107)
222 - fixes for building with newer MinGW versions
223 - fix for building with bison 2.4 (#111)
224 - fixed building with libgig installed in a non-standard directory
225 - minor fix in configure for mmsystem.h detection on MinGW
226 - Windows: look for editor plugins and Fantasia using base
227 directory of liblinuxsampler dll (look in the same directory and one
228 directory above)
229 - configure script fix: removed unconditional use of SSE
230 - fixed building with sqlite installed in a non-standard directory
231 - when cross-compiling, don't try to create instruments.db
232 - fix for new mingw-w64 version, which has usleep
233
234 * general changes:
235 - bugfix: on some POSIX systems instrument editor plugins refused to
236 load as we used a non-portable Linux specific struct field
237 (fixes bug #70, patch by Ronald Baljeu)
238 - fixed endless loop which occured when loading an instrument editor
239 plugin DLL on Windows systems failed
240 - fixed memory leaks that occurred when liblinuxsampler was unloaded
241 - optimized the SynchronizedConfig class so it doesn't wait
242 unnecessarily long after an update
243 - added support for notifying instrument editors on note-on / note-off
244 events (e.g. to highlight the pressed keys on the virtual keyboard
245 of gigedit)
246 - added support for triggering notes by instrument editors (see above)
247 - be verbose on DLL load errors (on Linux)
248 - fixed di-harmonic triangle LFO implementation (this LFO implementation
249 is only used by very few systems, most pick the int math
250 implementation, which is usually faster)
251 - fixes for audio drivers with varying buffer sizes
252 - experimental support for running LinuxSampler as a DSSI, LV2 and
253 VST plugin
254 - notification events for stream/voice count statistics are now sent
255 only when there are actual changes
256 - added memory ordering constraints to improve stability on
257 multi-core and multi-cpu systems
258 - maximum voices and disk streams can now be altered at runtime
259 - fixed CPU feature detection on x86_64 (maybe fixes #108)
260 - automatic stacktrace mechanism is now turned off by default and can
261 be switched on by command line option "--stacktrace" (the automatic
262 stacktrace mechanism seems to be broken on most systems at the moment)
263 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
264 a pointer to the launched InstrumentEditor object
265 - added optional 3rd party user data parameter for following
266 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
267 InstrumentEditor::Launch(),
268 InstrumentManager::LaunchInstrumentEditor()
269 - theoretical fix: made SynchronizedConfig follow C++0x memory
270 model more strictly
271 - fixes for using large audio device buffers
272 - Windows: add the installation directory to the DLL search path
273 when loading an editor plugin (solves problems with VST and
274 gigedit on systems with other GTK versions installed)
275
276 * audio driver:
277 - removed the nonsense audio channel constraint (which was hard coded to
278 max. 100 audio channels) for most audio drivers
279 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
280 opposed to the LSCP specs
281 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
282 reflected the wrong value
283 - fixed a memory management bug in ASIO driver
284 - Makefile fix: JACK_CFLAGS wasn't used
285 - JACK: use jack_client_open instead of the deprecated
286 jack_client_new
287 - added (experimental) CoreAudio driver
288 - applied old fixes to the ASIO driver that were included in the
289 previous binary release but accidentally never committed to CVS
290 (fixes #117)
291 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
292 win64)
293 - VST: added support for sample rate and buffer size changes
294 - VST: close editor (Fantasia) when the VST is removed
295 - VST: avoid opening Fantasia more than once for each VST instance
296 - VST: export main function as "main" on Linux too (fix for
297 energyXT)
298 - VST: changed number of output channels from one stereo to 16
299 stereo
300 - added channel routing, fxsends and midi maps to the settings
301 stored in the plugin state
302 - performance optimization of AudioChannel::MixTo() and
303 AudioChannel::CopyTo() methods using GCC vector exensions
304 (if available)
305 - ASIO fixes: avoid initializing the device twice, avoid throwing
306 exception when getting parameters from a disconnected device
307
308 * MIDI driver:
309 - added JACK MIDI driver
310 - dispatch bank select as ordinary CC as well, the user might seriously
311 want to (mis)use it for some purpose ("fixed" in all current MIDI
312 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
313 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
314 CoreMidi or AU
315 - fixed mingw-w64 compilation error in MME driver
316 - made program change handling in MIDI thread real-time safe by
317 moving the logic to a non-RT thread
318 - fixed minor memory leak in ALSA driver
319
320 * instruments database:
321 - avoid time consuming samples scanning when adding instruments
322 to the instruments database
323 - added support for handling lost files in the instruments database
324 - Implemented option for adding instruments in separate directories
325 in the instruments database
326 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
327 - work-around for missing fnmatch function on Windows to make
328 instrument database compilable
329 - added instrument database support on Windows
330 works with both standalone mode and VST plugin.
331 the instruments DB file is located in
332 %USERPROFILE%\.linuxsampler\instruments.db which allows different
333 databases for each windows user
334 if no DB is present it automatically creates the .linuxsampler subdir
335 and then creates an empty DB
336 - fixed recursive import, which was broken on Windows
337
338 * Gigasampler format engine:
339 - fixed a memory leak that could happen when a channel was deleted
340 while notes were playing
341 - made it possible to load an instrument even if the audio thread
342 isn't running
343 - added partial support for the "Controller Triggered" MIDI rule,
344 enough for piano gigs with pedal noise samples
345 - minor fix: only mark FX sends as being modified if really the
346 respective FX send MIDI controller was used
347 - added support for GM global device volume SysEx message
348 (can be selected at compile time to either apply globally to the
349 whole sampler [default] or only to the sampler channels that are
350 connected to the respective MIDI input port the SysEx message arrived
351 on)
352 - bugfix: notes triggered at position 0 in the audio buffer were
353 sometimes wrongly killed in the same buffer, causing no sound to
354 be played
355 - added support for chromatic / drumkit mode Roland GS Sysex message
356 which is usally used to switch a part between chromatic sounds and
357 drumkit sounds (as opposed to their common default setting of MIDI
358 part 10 being a drumkit part and all other ones chromatic parts), in
359 LS however one can switch between the first 16 MIDI instrument maps
360 defined for the sampler
361 - made it possible to create multiple sample channels even if the
362 audio thread isn't running
363 - fixed crash when removing channel with active voices (#116)
364 - bugfix: on sample reference changes (instrument editor), only
365 un-cache the respective sample if it's really not used by any
366 sampler engine anymore
367 - re-cache samples in case they were changed by an instrument editor,
368 e.g. when a sample was added while playing (#82)
369 - fixed hanging notes which occured when note-off event had the exact
370 same time stamp as the voice's note-on event and occured both in the
371 same audio fragment cycle (fixes bug #112)
372 - added support for the "fine tune" and "pitch bend range"
373 instrument-level gig parameters
374 - fixed minor artifacts in pitch bend handling
375 - added support for GS Reset SysEx message
376 - allow gig files to use unlimited downward pitch shifting
377 - added a limit check for upward pitch shifting
378 - bugfix: sometimes, when playing a note twice fast, the second
379 note was silent
380 - fixed crash happening when a pitch bend event arrived at the
381 same time a new instrument was loading
382
383 * LSCP server:
384 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
385 react on MIDI data arriving on certain sampler channels (so far only
386 Note-On and Note-Off events are sent via this LSCP event)
387 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
388 react on MIDI data arriving on certain MIDI input devices (so far only
389 Note-On and Note-Off events are sent via this LSCP event)
390 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
391 SET DB_INSTRUMENT FILE_PATH
392 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
393 frontends to send MIDI messages to specific sampler channel
394 - added two additional fields to GET FILE INSTRUMENT INFO command -
395 KEY_BINDINGS and KEYSWITCH_BINDINGS
396 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
397 was incorrect
398 - Optimized the retrieval of the MIDI instrument mappings
399 - added new LSCP command "SET VOICES" to globally alter the maximum
400 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
401 be triggered respectively
402 - added new LSCP command "SET STREAMS" to globally alter the maximum
403 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
404 which will be triggered respectively
405 - bugfix: retry if "select" returns EINTR (this fixes a crash when
406 a gigedit file dialog is opened)
407 - close all connections when LSCPServer is deleted
408 - hard close of all sockets on exit
409 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
410 driver
411
412 * Bug fixes:
413 - fixed a crash which occurs when removing a sampler channel waiting
414 to start instrument loading after another channel
415 - fixed a crash which occurs when removing a sampler channel with
416 instrument loading in progress (bug #113)
417 - fixed termination caused by uncaught exception when adding MIDI
418 instrument with PERSISTENT load mode
419 - fixed possible iterator invalidations when resetting the sampler
420 - fixed memory leaks when issuing the following LSCP commands:
421 GET AUDIO_OUTPUT_DRIVER INFO
422 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
423 GET MIDI_INPUT_DRIVER INFO
424 GET MIDI_INPUT_DRIVER_PARAMETER INFO
425 - fixed possible compilation error when sqlite is not present
426 - fixed orphaned pointers when setting maximum voices limit (bug #118)
427 - fixed crash when changing the audio output device of a sampler
428 channel with loaded instrument and start playing notes
429 - fixed endless loop in Engine::SuspendAll() (bug #120)
430 - fixed a low-level atomic load function that was broken on 64-bit
431 PowerPC, which probably could cause crashes on that platform
432 - fixed a memory management error which could cause a crash when a
433 plugin was unloaded
434 - bugfix: two private structs had the same name, which could cause
435 problems if the linker chose the wrong constructor
436 - fixed low-level ConditionServer usage bug that caused lockups on
437 Windows
438
439
440 Version 0.5.1 (6 December 2007)
441
442 * packaging changes:
443 - added autoconf checks for pthread library
444 - added autoconf check for pthread bug found on certain NPTL-enabled
445 glibc versions (see Gentoo bug report #194076)
446 - added autoconf checks for MS Windows
447
448 * general changes:
449 - bugfix: the thread used by an editor plugin didn't die when the
450 editor closed
451 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
452 out all the space. operator--() did not apply size_mask after
453 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
454 order to avoid problems with the _NonVolatileReader functions.
455 - bugfix: Stream.h: added a missing divide by BytesPerSample in
456 GetWriteSpace(). Since this function is currently only used in
457 the stream's qsort() compare function, it didn't trigger any
458 bugs.
459 - Resampler.h, Synthesizer.h: cubic interpolation now works in
460 24bit mode too. Faster method to read 24bit words on little
461 endian machines (x86): replaced 3 byte reads + shifts with a 1
462 unaligned 32bit read and shift
463 - experimental support for MS Windows (MIDI input via MME, AUDIO
464 output via ASIO)
465 - made handling of SIGINT signal (Ctrl-C) a bit more robust
466 - support for monitoring the total number of active disk streams
467 (new LSCP commands: GET TOTAL_STREAM_COUNT,
468 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
469
470 * AUDIO driver:
471 - added Windows ASIO low latency audio driver
472
473 * MIDI driver:
474 - added MME Windows MIDI driver
475
476 * LSCP server:
477 - added support for Windows style path / filenames, however with
478 forward slash path separators instead of backslash
479 (i.e. "C:/foo/bar.gig")
480 - allow naughty liblscp to send non-string device parameters within
481 apostrophes as well
482 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
483 "LIST FILE INSTRUMENTS <file>" and
484 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
485 about an arbitrary instrument file on the system where the sampler is
486 running on
487
488 Version 0.5.0 (15 October 2007)
489
490 * packaging changes:
491 - config.h is not going to be installed along with liblinuxsampler's
492 API header files anymore
493 - only the API relevant header (and source) files will be exported to
494 the Doxygen API documentation (explicitly listed in Doxyfile.in)
495 - added completely new XCode project files for Mac OSX which is now
496 capable to execute our autoconf environment, thus no need anymore
497 to maintain the compile time configuration file (osx/version.h) for
498 OSX manually (patch by Toshi Nagata)
499 - fixed buggy boolean --enable-foo / --disable-foo configure script
500 parameters
501 - global.h now only covers global definitions that are needed for the
502 C++ API header files, all implementation internal global definitions
503 are now in global_private.h
504 - atomic.h is not exposed to the C++ API anymore
505 - no need to include config.h anymore for using LS's API header files
506 - fixed warnings in API doc generation
507
508 * general changes:
509 - replaced the old, confusing MIDI program change mechanism by a
510 flexible MIDI instrument mapper which allows to map arbitrary
511 (MIDI bank, MIDI program) pairs with arbitrary
512 (engine type, instrument file, file index) triplets which will be
513 loaded on the respective channel when such MIDI program change
514 messages arrive, beside that, each entry allows to define a life-time
515 strategy for the instrument, so the user can define whether the
516 instrument should i.e. be permanently loaded (to be able to switch
517 quickly among sounds) or i.e. loaded just on demand when the
518 respective program change arrives (to safe RAM space), as well as a
519 global volume factor for each entry, so the user can adjust the volume
520 dynamic of his mapped instrument collection without having to modify
521 the instrument files, also one can manage arbitrary amount of such
522 MIDI instrument maps and assign each sampler channel individually
523 a certain map, so that i.e. separation of normal instruments and
524 drumkits is possible
525 - new notification events for tracking changes to audio/MIDI devices,
526 MIDI instrument maps, MIDI instruments, FX sends, global volume.
527 - sampler was limited to load max. 200 instruments in the background
528 due to a constant size RingBuffer FIFO which is now replaced by a
529 dynamic (unlimited) size std::list FIFO
530 - added FX sends, these allow to route audio signals to arbitrary audio
531 output channels for being processed by external effect processors
532 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
533 controllers
534 - global (sampler wide) volume can now be controlled at runtime
535 - Implemented new, improved notification system
536 - fixed compilation errors regarding OSX
537 (patch by Toshi Nagata)
538 - implemented instruments database
539 - added support for escape sequences to the instruments database
540 - added highly experimental support for on-the-fly instrument editing
541 within the sampler's process (by using instrument editor plugins),
542 you'll notice the new "Registered instrument editors:" message on
543 startup, added a new LSCP command:
544 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
545 to spawn a matching instrument editor for the instrument on the
546 given sampler channel, the plugin path can be overridden at compile
547 time with ./configure --enable-plugin-dir=/some/dir
548 - added experimental code for synchronizing instrument editors hosted
549 in the sampler's process to safely edit instruments while playing
550 without a crash (hopefully) by either suspending single regions
551 wherever possible or if unavoidable whole engine(s)
552 - fixed several issues in fundamental "Thread" class: set scheduling
553 policy and priority on thread level, set a minimum stack size for
554 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
555 threads simply inherited properties of starting thread instead of
556 setting their own policy and priority
557 - minor fix in our automatic stack trace mechanism on crashes, the
558 main process did not wait for the stack trace process to finish
559 its output
560 - fixed some minor memory leaks
561 - reenabled assembly features support, at the moment only for
562 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
563 - minor assembly fix in x86 features detection (don't use the PIC
564 register, to avoid relocations in the text segment at runtime)
565 - POSIX callback functions of Thread.h are hidden
566
567 * MIDI driver:
568 - dispatch bank select (MSB and LSB) messages
569
570 * audio driver:
571 - the ALSA audio output driver parameters now reflect the correct
572 parameter value ranges for the respective selected sound card
573 (patch by Till Wimmer, a bit fixed and extended)
574
575 * Gigasampler format engine:
576 - if a filter is used and EG2 finishes before EG1, let the voice
577 die when EG2 has finished (this fixes a problem with clicks and
578 voice starvation for some gigs)
579 - playback is no longer disabled during instrument loading
580 - all notes playing on a channel that changes its instrument keep
581 playing with the old instrument until they get a note off
582 command
583 - EG fix: a release value of zero could cause noises or crash
584 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
585 - EG fine tuning: when attack is zero the EG starts at a level
586 above max sustain level, which means that there is a decay phase
587 even if sustain is 100%
588 - more EG fixes: the level could sometimes go below zero and cause
589 noises or crashes
590 - minor fix of EGDecay (patch by Toshi Nagata)
591 - fixed compiler error when --enable-override-filter-type was
592 supplied to the configure script (fixes #46)
593 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
594 instead of a fix value
595 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
596 127 (solo mode) only kill voices if the respective mode really
597 changed
598
599 * LSCP server:
600 - fixed compile time error for old Bison versions
601 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
602 - parser now supports extended ASCII character set
603 (up to ASCII code 255, i.e. includes now umlauts and accents)
604 - filename arguments in LSCP commands now allow to use escape
605 sequences, that is directly literal as one of: \', \", \\, \n, \r,
606 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
607 code value like \xf2) (fixes bug #24)
608 - the following LSCP commands now also support escape sequences for at
609 least one of their text-based parameters (i.e. name, description):
610 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
611 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
612 "SET DB_INSTRUMENT_DIRECTORY NAME",
613 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
614 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
615 "FIND DB_INSTRUMENT_DIRECTORIES"
616 - returns verbose syntax errors (line and column where syntax error
617 occured, the unexpected character and the actually expected, possible
618 character(s), the latter only if less than 5 possibilities)
619 - made sure that LSCP syntax is not affected by gigedit locale
620 settings
621 - bugfix regarding strings parameter lists: all comma separated lists
622 of strings were treated as being one string containing commas
623 (fixes #57)
624
625 * Bug fixes:
626 - fixed crash occurring on certain LSCP scripts (Bug 39)
627 - another thread safety fix for lscp "load engine" and "set
628 channel audio output device"
629 - fixed a crash which occurs when reassigning the same engine
630 on a sampler channel with connected MIDI device
631 - fixed a crash which occurs when changing the number of ports of a MIDI
632 device connected to a sampler channel to number less then or equal
633 to the index of the port to which the sampler channel is connected.
634 - The previous bindings were not been disconnected when altering
635 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
636 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
637 - The active stream/voice count statistic was incorrect.
638 - notification events were not been sent for some sampler
639 channel changes
640 - added default min and max values to restrict the number of allowed
641 audio output channels and MIDI input ports
642 - the connection to the PCM interface is now closed when destroying
643 an audio output device
644 - files with slash in their path or filename could not be loaded
645
646 * test cases:
647 - updated and fixed (haven't been touched in a while)
648
649 Version 0.4.0 (24 November 2006)
650
651 * packaging changes:
652 - changed deprecated copyright attribute to license; added ldconfig
653 to post-(un)install steps; added devel package for liblinuxsampler;
654 to linuxsampler.spec (RPM)
655 - install necessary development header files for allowing 3rd party
656 applications to link against liblinuxsampler
657 - liblinuxsampler's API documentation can be generated with 'make docs'
658 (Doxygen required)
659 - added benchmark to automatically detect the best triangle LFO
660 implementation (currently either an integer math solution or a
661 di-harmonic approximation), automatic detection can be overriden
662 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
663 configure script argument though (mandatory for cross-compilation)
664 - do not automatically pick optimized gcc flags if the user already
665 provided some on his own (as CXXFLAGS)
666 - added compile time option to disable processing of All-Notes-Off MIDI
667 messages
668 - added compile time options to allow disabling the various audio and
669 MIDI drivers
670 - fixed automatic GCC CPU switch detection on PPC
671 (patch by Ebrahim Mayat)
672
673 * Gigasampler format engine:
674 - extensive synthesis optimization
675 (reimplementation of EGs and LFO(s), removed synthesis parameter
676 prerendering and the synthesis parameter matrix in general, splitting
677 each audio fragment into subfragments now where each subfragment uses
678 constant pitch and filter coefficients. The volume coefficient is
679 linearly interpolated inside a subfragment, unless
680 --disable-interpolate-volume is set.)
681 - fine tuning of the EG modulation parameters
682 - improved filter cutoff calculation by adding support for the
683 following gig parameters: Cutoff freq (used when no cutoff
684 controller is defined), Control invert, Minimum cutoff, Velocity
685 curve and Velocity range. The keyboard tracking now scales
686 cutoff frequency instead of resonance.
687 - added support for gig parameter Resonance.
688 - fixed bug in sysex handling (patch by Juan Linietsky)
689 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
690 which can be overridden with --enable-global-attenuation
691 - EG fixes: made the length of "attack hold" stage more
692 accurate. Release stage can now start before attack stage
693 ends. Cancel release didn't work when sustain was zero. Attack
694 time now has a minimal value to prevent clicks.
695 - fixed pitch changes larger than one octave
696 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
697 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
698 all modes can be altered via standard GM messages, that is CC5 for
699 altering portamento time, CC65 for enabling / disabling portamento
700 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
701 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
702 parameter) and crossfade
703 - added support for the "attenuation controller threshold" gig
704 parameter
705 - added smoothing of volume changes caused by control change
706 messages
707 - sample loop parameters are now taken from the DimensionRegion
708 instead of the wave chunk
709 - fixed keyswitching for v3 gigs with a number of keyswitch splits
710 not equal to a power of two
711 - reimplementation of the filter algorithm. The new filter is more
712 accurate and supports all gig filter types, including bandreject
713 and lowpass turbo.
714 - real support for 24 bit samples - samples are not truncated to
715 16 bits anymore
716 - support for aftertouch (channel pressure, not polyphonic
717 aftertouch)
718 - LFO1 behaviour fixed (dampening from max volume instead of
719 amplifying from 0)
720
721 * LSCP server:
722 - fixed application exit on broken pipe error (fixes bug #20)
723 - fixed the notification messages delay due to lack of
724 network activity (fixes bug #26)
725 - fixed parser bug which occured on space(s) within device parameters
726 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
727
728 * audio driver:
729 - added aRts audio output driver (by no means RT safe)
730
731 * MIDI driver:
732 - fixed legacy sysex code which caused dispatching of MIDI SysEx
733 messages several times instead of once
734 - API extension for MIDI drivers which already supply exact time stamps
735 for events (i.e. for offline rendering based MIDI drivers)
736 - added checks for bad MIDI data
737
738 * linuxsampler application:
739 - show available sampler engine types on startup
740
741 * general changes:
742 - support for muting sampler channels and solo mode of the same, two new
743 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
744 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
745 introduced for this, the behavior is the same like on a mixer console
746 (patch by Grigor Iliev, a bit adjusted). Also added configure option
747 --enable-process-muted-channels which can be used to enable the
748 processing of muted channels.
749 - support for sostenuto pedal
750 - support for monitoring the total number of active voices
751 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
752 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
753 - fixed some memory management errors
754 - fixed some concurrency problems that could lead to crashes when
755 LSCP commands were executed
756 - fixed crash when instrument loading failed previously on the same
757 sampler channel (fixes bug #36)
758
759 Version 0.3.3 (15 July 2005)
760
761 * packaging changes:
762 - fixed compilation with gcc 4.0
763
764 * Gigasampler format engine:
765 - LFO preprocessing was performed even though the respective LFO was
766 disabled by the instrument patch (minor efficiency fix)
767 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
768 for volume ramp downs in the same fragment (needed for current voice
769 stealing implementation) then simply inform the user with a warning
770 about possible click sounds and reduce the volume ramp down
771 appropriately instead of cancelling the audio device connection
772
773 Version 0.3.2 (24 June 2005)
774
775 * packaging changes:
776 - updated autotools build files to compile on OS X
777 (conditional compilation of CoreMIDI and MidiShare drivers)
778 - hand-crafted assembly optimization code can be disabled with
779 './configure --disable-asm' (definitely not recommended)
780 - fixed 'make dist' rule to include all necessary files
781 - require automake (>= 1.5) for 'make -f Makefile.cvs'
782 (due to 'dist-bzip2' automake option)
783
784 * Gigasampler format engine:
785 - support for the gig parameters for "release velocity response" curves
786 - fine tuning of the EGADSR envelope
787 - volume of release triggered samples now depends on note-on velocity,
788 note length and gig parameter "release trigger decay" instead of
789 note-off velocity.
790 - revised voice stealing
791 (fixes crash and endless loop caused by voice stealing)
792 - don't reset scale tuning on instrument or audio output device change
793 - handle key group conflicts right at the beginning of each fragment
794 instead of when the respective voice is actually launched
795 (fixes undefined behavior if stolen voices belonged to a key group -
796 this case was followed by a "killed voice survived" error message)
797 - fixed minor issue with null/silence samples
798 (those stole voices even though they don't need a voice at all which
799 resulted in "voice stealing didn't work out" messages)
800 - don't reset volume, pan, pitch and MIDI controller values on
801 instrument or audio output device change
802
803 * LSCP server:
804 - fixed some crashes (patch by Grigor Iliev, fixes #19)
805 - fixed LSCP event "CHANNEL_INFO" notification
806 (e.g. did not notify on volume changes or MIDI program change events)
807
808 * linuxsampler application:
809 - added command line parameters --lscp-addr and --lscp-port to override
810 default IP address and port of LSCP server
811
812 Version 0.3.1 (24 May 2005)
813
814 * initial release
