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

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

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

258 channel to a different engine type
259 - fixed crash when deleting a sampler channel or changing engine
260 type while an instrument load was in progress
261 - bugfix: playing a note while changing the instrument could cause
262 a crash, or give "Handing back unknown region" error messages
263 - bugfix: calling SET VOICES (which Fantasia does on start and
264 refresh) could cause instruments to be unloaded
265 - Mac OS X: fixed name collision of enum in EffectControl and
266 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
267 - Mac OS X: fixed hanging threads
268 - Windows: disabled the previous thread fix on non-Mac systems, as
269 it caused hanging threads on Windows
270 - Fixed possible crashes due to corrupted MIDI/audio device list
271 after MIDI/audio device creation failure
272 - When creating MIDI instrument map entries with "PERSISTENT" type, the
273 instruments were uselessly precached with zero samples, however it still
274 took the full preloading time and on 1st program change the respective
275 instrument was completely reloaded again.
276 - fixed handling of rapid bank select and program change messages
277 sent to the same sampler channel (patch from the Open Octave
278 project, slightly adjusted)
279 - fixed crash when trying to create an effect instance with controls
280 which min and/or max values depend on the sample rate
281
282 Version 1.0.0 (31 July 2009)
283
284 * packaging changes:
285 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
286 causing e.g. the libgig test to fail when
287 "./configure --disable-jack-driver" was used
288 (patch by Alexis Ballier)
289 - fixed compilation with gcc 4.3
290 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
291 - fixed configure so it detects x86_64 (#107)
292 - fixes for building with newer MinGW versions
293 - fix for building with bison 2.4 (#111)
294 - fixed building with libgig installed in a non-standard directory
295 - minor fix in configure for mmsystem.h detection on MinGW
296 - Windows: look for editor plugins and Fantasia using base
297 directory of liblinuxsampler dll (look in the same directory and one
298 directory above)
299 - configure script fix: removed unconditional use of SSE
300 - fixed building with sqlite installed in a non-standard directory
301 - when cross-compiling, don't try to create instruments.db
302 - fix for new mingw-w64 version, which has usleep
303
304 * general changes:
305 - bugfix: on some POSIX systems instrument editor plugins refused to
306 load as we used a non-portable Linux specific struct field
307 (fixes bug #70, patch by Ronald Baljeu)
308 - fixed endless loop which occured when loading an instrument editor
309 plugin DLL on Windows systems failed
310 - fixed memory leaks that occurred when liblinuxsampler was unloaded
311 - optimized the SynchronizedConfig class so it doesn't wait
312 unnecessarily long after an update
313 - added support for notifying instrument editors on note-on / note-off
314 events (e.g. to highlight the pressed keys on the virtual keyboard
315 of gigedit)
316 - added support for triggering notes by instrument editors (see above)
317 - be verbose on DLL load errors (on Linux)
318 - fixed di-harmonic triangle LFO implementation (this LFO implementation
319 is only used by very few systems, most pick the int math
320 implementation, which is usually faster)
321 - fixes for audio drivers with varying buffer sizes
322 - experimental support for running LinuxSampler as a DSSI, LV2 and
323 VST plugin
324 - notification events for stream/voice count statistics are now sent
325 only when there are actual changes
326 - added memory ordering constraints to improve stability on
327 multi-core and multi-cpu systems
328 - maximum voices and disk streams can now be altered at runtime
329 - fixed CPU feature detection on x86_64 (maybe fixes #108)
330 - automatic stacktrace mechanism is now turned off by default and can
331 be switched on by command line option "--stacktrace" (the automatic
332 stacktrace mechanism seems to be broken on most systems at the moment)
333 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
334 a pointer to the launched InstrumentEditor object
335 - added optional 3rd party user data parameter for following
336 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
337 InstrumentEditor::Launch(),
338 InstrumentManager::LaunchInstrumentEditor()
339 - theoretical fix: made SynchronizedConfig follow C++0x memory
340 model more strictly
341 - fixes for using large audio device buffers
342 - Windows: add the installation directory to the DLL search path
343 when loading an editor plugin (solves problems with VST and
344 gigedit on systems with other GTK versions installed)
345
346 * audio driver:
347 - removed the nonsense audio channel constraint (which was hard coded to
348 max. 100 audio channels) for most audio drivers
349 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
350 opposed to the LSCP specs
351 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
352 reflected the wrong value
353 - fixed a memory management bug in ASIO driver
354 - Makefile fix: JACK_CFLAGS wasn't used
355 - JACK: use jack_client_open instead of the deprecated
356 jack_client_new
357 - added (experimental) CoreAudio driver
358 - applied old fixes to the ASIO driver that were included in the
359 previous binary release but accidentally never committed to CVS
360 (fixes #117)
361 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
362 win64)
363 - VST: added support for sample rate and buffer size changes
364 - VST: close editor (Fantasia) when the VST is removed
365 - VST: avoid opening Fantasia more than once for each VST instance
366 - VST: export main function as "main" on Linux too (fix for
367 energyXT)
368 - VST: changed number of output channels from one stereo to 16
369 stereo
370 - added channel routing, fxsends and midi maps to the settings
371 stored in the plugin state
372 - performance optimization of AudioChannel::MixTo() and
373 AudioChannel::CopyTo() methods using GCC vector exensions
374 (if available)
375 - ASIO fixes: avoid initializing the device twice, avoid throwing
376 exception when getting parameters from a disconnected device
377
378 * MIDI driver:
379 - added JACK MIDI driver
380 - dispatch bank select as ordinary CC as well, the user might seriously
381 want to (mis)use it for some purpose ("fixed" in all current MIDI
382 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
383 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
384 CoreMidi or AU
385 - fixed mingw-w64 compilation error in MME driver
386 - made program change handling in MIDI thread real-time safe by
387 moving the logic to a non-RT thread
388 - fixed minor memory leak in ALSA driver
389
390 * instruments database:
391 - avoid time consuming samples scanning when adding instruments
392 to the instruments database
393 - added support for handling lost files in the instruments database
394 - Implemented option for adding instruments in separate directories
395 in the instruments database
396 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
397 - work-around for missing fnmatch function on Windows to make
398 instrument database compilable
399 - added instrument database support on Windows
400 works with both standalone mode and VST plugin.
401 the instruments DB file is located in
402 %USERPROFILE%\.linuxsampler\instruments.db which allows different
403 databases for each windows user
404 if no DB is present it automatically creates the .linuxsampler subdir
405 and then creates an empty DB
406 - fixed recursive import, which was broken on Windows
407
408 * Gigasampler format engine:
409 - fixed a memory leak that could happen when a channel was deleted
410 while notes were playing
411 - made it possible to load an instrument even if the audio thread
412 isn't running
413 - added partial support for the "Controller Triggered" MIDI rule,
414 enough for piano gigs with pedal noise samples
415 - minor fix: only mark FX sends as being modified if really the
416 respective FX send MIDI controller was used
417 - added support for GM global device volume SysEx message
418 (can be selected at compile time to either apply globally to the
419 whole sampler [default] or only to the sampler channels that are
420 connected to the respective MIDI input port the SysEx message arrived
421 on)
422 - bugfix: notes triggered at position 0 in the audio buffer were
423 sometimes wrongly killed in the same buffer, causing no sound to
424 be played
425 - added support for chromatic / drumkit mode Roland GS Sysex message
426 which is usally used to switch a part between chromatic sounds and
427 drumkit sounds (as opposed to their common default setting of MIDI
428 part 10 being a drumkit part and all other ones chromatic parts), in
429 LS however one can switch between the first 16 MIDI instrument maps
430 defined for the sampler
431 - made it possible to create multiple sample channels even if the
432 audio thread isn't running
433 - fixed crash when removing channel with active voices (#116)
434 - bugfix: on sample reference changes (instrument editor), only
435 un-cache the respective sample if it's really not used by any
436 sampler engine anymore
437 - re-cache samples in case they were changed by an instrument editor,
438 e.g. when a sample was added while playing (#82)
439 - fixed hanging notes which occured when note-off event had the exact
440 same time stamp as the voice's note-on event and occured both in the
441 same audio fragment cycle (fixes bug #112)
442 - added support for the "fine tune" and "pitch bend range"
443 instrument-level gig parameters
444 - fixed minor artifacts in pitch bend handling
445 - added support for GS Reset SysEx message
446 - allow gig files to use unlimited downward pitch shifting
447 - added a limit check for upward pitch shifting
448 - bugfix: sometimes, when playing a note twice fast, the second
449 note was silent
450 - fixed crash happening when a pitch bend event arrived at the
451 same time a new instrument was loading
452
453 * LSCP server:
454 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
455 react on MIDI data arriving on certain sampler channels (so far only
456 Note-On and Note-Off events are sent via this LSCP event)
457 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
458 react on MIDI data arriving on certain MIDI input devices (so far only
459 Note-On and Note-Off events are sent via this LSCP event)
460 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
461 SET DB_INSTRUMENT FILE_PATH
462 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
463 frontends to send MIDI messages to specific sampler channel
464 - added two additional fields to GET FILE INSTRUMENT INFO command -
465 KEY_BINDINGS and KEYSWITCH_BINDINGS
466 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
467 was incorrect
468 - Optimized the retrieval of the MIDI instrument mappings
469 - added new LSCP command "SET VOICES" to globally alter the maximum
470 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
471 be triggered respectively
472 - added new LSCP command "SET STREAMS" to globally alter the maximum
473 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
474 which will be triggered respectively
475 - bugfix: retry if "select" returns EINTR (this fixes a crash when
476 a gigedit file dialog is opened)
477 - close all connections when LSCPServer is deleted
478 - hard close of all sockets on exit
479 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
480 driver
481
482 * Bug fixes:
483 - fixed a crash which occurs when removing a sampler channel waiting
484 to start instrument loading after another channel
485 - fixed a crash which occurs when removing a sampler channel with
486 instrument loading in progress (bug #113)
487 - fixed termination caused by uncaught exception when adding MIDI
488 instrument with PERSISTENT load mode
489 - fixed possible iterator invalidations when resetting the sampler
490 - fixed memory leaks when issuing the following LSCP commands:
491 GET AUDIO_OUTPUT_DRIVER INFO
492 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
493 GET MIDI_INPUT_DRIVER INFO
494 GET MIDI_INPUT_DRIVER_PARAMETER INFO
495 - fixed possible compilation error when sqlite is not present
496 - fixed orphaned pointers when setting maximum voices limit (bug #118)
497 - fixed crash when changing the audio output device of a sampler
498 channel with loaded instrument and start playing notes
499 - fixed endless loop in Engine::SuspendAll() (bug #120)
500 - fixed a low-level atomic load function that was broken on 64-bit
501 PowerPC, which probably could cause crashes on that platform
502 - fixed a memory management error which could cause a crash when a
503 plugin was unloaded
504 - bugfix: two private structs had the same name, which could cause
505 problems if the linker chose the wrong constructor
506 - fixed low-level ConditionServer usage bug that caused lockups on
507 Windows
508
509
510 Version 0.5.1 (6 December 2007)
511
512 * packaging changes:
513 - added autoconf checks for pthread library
514 - added autoconf check for pthread bug found on certain NPTL-enabled
515 glibc versions (see Gentoo bug report #194076)
516 - added autoconf checks for MS Windows
517
518 * general changes:
519 - bugfix: the thread used by an editor plugin didn't die when the
520 editor closed
521 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
522 out all the space. operator--() did not apply size_mask after
523 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
524 order to avoid problems with the _NonVolatileReader functions.
525 - bugfix: Stream.h: added a missing divide by BytesPerSample in
526 GetWriteSpace(). Since this function is currently only used in
527 the stream's qsort() compare function, it didn't trigger any
528 bugs.
529 - Resampler.h, Synthesizer.h: cubic interpolation now works in
530 24bit mode too. Faster method to read 24bit words on little
531 endian machines (x86): replaced 3 byte reads + shifts with a 1
532 unaligned 32bit read and shift
533 - experimental support for MS Windows (MIDI input via MME, AUDIO
534 output via ASIO)
535 - made handling of SIGINT signal (Ctrl-C) a bit more robust
536 - support for monitoring the total number of active disk streams
537 (new LSCP commands: GET TOTAL_STREAM_COUNT,
538 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
539
540 * AUDIO driver:
541 - added Windows ASIO low latency audio driver
542
543 * MIDI driver:
544 - added MME Windows MIDI driver
545
546 * LSCP server:
547 - added support for Windows style path / filenames, however with
548 forward slash path separators instead of backslash
549 (i.e. "C:/foo/bar.gig")
550 - allow naughty liblscp to send non-string device parameters within
551 apostrophes as well
552 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
553 "LIST FILE INSTRUMENTS <file>" and
554 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
555 about an arbitrary instrument file on the system where the sampler is
556 running on
557
558 Version 0.5.0 (15 October 2007)
559
560 * packaging changes:
561 - config.h is not going to be installed along with liblinuxsampler's
562 API header files anymore
563 - only the API relevant header (and source) files will be exported to
564 the Doxygen API documentation (explicitly listed in Doxyfile.in)
565 - added completely new XCode project files for Mac OSX which is now
566 capable to execute our autoconf environment, thus no need anymore
567 to maintain the compile time configuration file (osx/version.h) for
568 OSX manually (patch by Toshi Nagata)
569 - fixed buggy boolean --enable-foo / --disable-foo configure script
570 parameters
571 - global.h now only covers global definitions that are needed for the
572 C++ API header files, all implementation internal global definitions
573 are now in global_private.h
574 - atomic.h is not exposed to the C++ API anymore
575 - no need to include config.h anymore for using LS's API header files
576 - fixed warnings in API doc generation
577
578 * general changes:
579 - replaced the old, confusing MIDI program change mechanism by a
580 flexible MIDI instrument mapper which allows to map arbitrary
581 (MIDI bank, MIDI program) pairs with arbitrary
582 (engine type, instrument file, file index) triplets which will be
583 loaded on the respective channel when such MIDI program change
584 messages arrive, beside that, each entry allows to define a life-time
585 strategy for the instrument, so the user can define whether the
586 instrument should i.e. be permanently loaded (to be able to switch
587 quickly among sounds) or i.e. loaded just on demand when the
588 respective program change arrives (to safe RAM space), as well as a
589 global volume factor for each entry, so the user can adjust the volume
590 dynamic of his mapped instrument collection without having to modify
591 the instrument files, also one can manage arbitrary amount of such
592 MIDI instrument maps and assign each sampler channel individually
593 a certain map, so that i.e. separation of normal instruments and
594 drumkits is possible
595 - new notification events for tracking changes to audio/MIDI devices,
596 MIDI instrument maps, MIDI instruments, FX sends, global volume.
597 - sampler was limited to load max. 200 instruments in the background
598 due to a constant size RingBuffer FIFO which is now replaced by a
599 dynamic (unlimited) size std::list FIFO
600 - added FX sends, these allow to route audio signals to arbitrary audio
601 output channels for being processed by external effect processors
602 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
603 controllers
604 - global (sampler wide) volume can now be controlled at runtime
605 - Implemented new, improved notification system
606 - fixed compilation errors regarding OSX
607 (patch by Toshi Nagata)
608 - implemented instruments database
609 - added support for escape sequences to the instruments database
610 - added highly experimental support for on-the-fly instrument editing
611 within the sampler's process (by using instrument editor plugins),
612 you'll notice the new "Registered instrument editors:" message on
613 startup, added a new LSCP command:
614 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
615 to spawn a matching instrument editor for the instrument on the
616 given sampler channel, the plugin path can be overridden at compile
617 time with ./configure --enable-plugin-dir=/some/dir
618 - added experimental code for synchronizing instrument editors hosted
619 in the sampler's process to safely edit instruments while playing
620 without a crash (hopefully) by either suspending single regions
621 wherever possible or if unavoidable whole engine(s)
622 - fixed several issues in fundamental "Thread" class: set scheduling
623 policy and priority on thread level, set a minimum stack size for
624 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
625 threads simply inherited properties of starting thread instead of
626 setting their own policy and priority
627 - minor fix in our automatic stack trace mechanism on crashes, the
628 main process did not wait for the stack trace process to finish
629 its output
630 - fixed some minor memory leaks
631 - reenabled assembly features support, at the moment only for
632 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
633 - minor assembly fix in x86 features detection (don't use the PIC
634 register, to avoid relocations in the text segment at runtime)
635 - POSIX callback functions of Thread.h are hidden
636
637 * MIDI driver:
638 - dispatch bank select (MSB and LSB) messages
639
640 * audio driver:
641 - the ALSA audio output driver parameters now reflect the correct
642 parameter value ranges for the respective selected sound card
643 (patch by Till Wimmer, a bit fixed and extended)
644
645 * Gigasampler format engine:
646 - if a filter is used and EG2 finishes before EG1, let the voice
647 die when EG2 has finished (this fixes a problem with clicks and
648 voice starvation for some gigs)
649 - playback is no longer disabled during instrument loading
650 - all notes playing on a channel that changes its instrument keep
651 playing with the old instrument until they get a note off
652 command
653 - EG fix: a release value of zero could cause noises or crash
654 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
655 - EG fine tuning: when attack is zero the EG starts at a level
656 above max sustain level, which means that there is a decay phase
657 even if sustain is 100%
658 - more EG fixes: the level could sometimes go below zero and cause
659 noises or crashes
660 - minor fix of EGDecay (patch by Toshi Nagata)
661 - fixed compiler error when --enable-override-filter-type was
662 supplied to the configure script (fixes #46)
663 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
664 instead of a fix value
665 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
666 127 (solo mode) only kill voices if the respective mode really
667 changed
668
669 * LSCP server:
670 - fixed compile time error for old Bison versions
671 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
672 - parser now supports extended ASCII character set
673 (up to ASCII code 255, i.e. includes now umlauts and accents)
674 - filename arguments in LSCP commands now allow to use escape
675 sequences, that is directly literal as one of: \', \", \\, \n, \r,
676 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
677 code value like \xf2) (fixes bug #24)
678 - the following LSCP commands now also support escape sequences for at
679 least one of their text-based parameters (i.e. name, description):
680 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
681 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
682 "SET DB_INSTRUMENT_DIRECTORY NAME",
683 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
684 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
685 "FIND DB_INSTRUMENT_DIRECTORIES"
686 - returns verbose syntax errors (line and column where syntax error
687 occured, the unexpected character and the actually expected, possible
688 character(s), the latter only if less than 5 possibilities)
689 - made sure that LSCP syntax is not affected by gigedit locale
690 settings
691 - bugfix regarding strings parameter lists: all comma separated lists
692 of strings were treated as being one string containing commas
693 (fixes #57)
694
695 * Bug fixes:
696 - fixed crash occurring on certain LSCP scripts (Bug 39)
697 - another thread safety fix for lscp "load engine" and "set
698 channel audio output device"
699 - fixed a crash which occurs when reassigning the same engine
700 on a sampler channel with connected MIDI device
701 - fixed a crash which occurs when changing the number of ports of a MIDI
702 device connected to a sampler channel to number less then or equal
703 to the index of the port to which the sampler channel is connected.
704 - The previous bindings were not been disconnected when altering
705 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
706 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
707 - The active stream/voice count statistic was incorrect.
708 - notification events were not been sent for some sampler
709 channel changes
710 - added default min and max values to restrict the number of allowed
711 audio output channels and MIDI input ports
712 - the connection to the PCM interface is now closed when destroying
713 an audio output device
714 - files with slash in their path or filename could not be loaded
715
716 * test cases:
717 - updated and fixed (haven't been touched in a while)
718
719 Version 0.4.0 (24 November 2006)
720
721 * packaging changes:
722 - changed deprecated copyright attribute to license; added ldconfig
723 to post-(un)install steps; added devel package for liblinuxsampler;
724 to linuxsampler.spec (RPM)
725 - install necessary development header files for allowing 3rd party
726 applications to link against liblinuxsampler
727 - liblinuxsampler's API documentation can be generated with 'make docs'
728 (Doxygen required)
729 - added benchmark to automatically detect the best triangle LFO
730 implementation (currently either an integer math solution or a
731 di-harmonic approximation), automatic detection can be overriden
732 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
733 configure script argument though (mandatory for cross-compilation)
734 - do not automatically pick optimized gcc flags if the user already
735 provided some on his own (as CXXFLAGS)
736 - added compile time option to disable processing of All-Notes-Off MIDI
737 messages
738 - added compile time options to allow disabling the various audio and
739 MIDI drivers
740 - fixed automatic GCC CPU switch detection on PPC
741 (patch by Ebrahim Mayat)
742
743 * Gigasampler format engine:
744 - extensive synthesis optimization
745 (reimplementation of EGs and LFO(s), removed synthesis parameter
746 prerendering and the synthesis parameter matrix in general, splitting
747 each audio fragment into subfragments now where each subfragment uses
748 constant pitch and filter coefficients. The volume coefficient is
749 linearly interpolated inside a subfragment, unless
750 --disable-interpolate-volume is set.)
751 - fine tuning of the EG modulation parameters
752 - improved filter cutoff calculation by adding support for the
753 following gig parameters: Cutoff freq (used when no cutoff
754 controller is defined), Control invert, Minimum cutoff, Velocity
755 curve and Velocity range. The keyboard tracking now scales
756 cutoff frequency instead of resonance.
757 - added support for gig parameter Resonance.
758 - fixed bug in sysex handling (patch by Juan Linietsky)
759 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
760 which can be overridden with --enable-global-attenuation
761 - EG fixes: made the length of "attack hold" stage more
762 accurate. Release stage can now start before attack stage
763 ends. Cancel release didn't work when sustain was zero. Attack
764 time now has a minimal value to prevent clicks.
765 - fixed pitch changes larger than one octave
766 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
767 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
768 all modes can be altered via standard GM messages, that is CC5 for
769 altering portamento time, CC65 for enabling / disabling portamento
770 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
771 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
772 parameter) and crossfade
773 - added support for the "attenuation controller threshold" gig
774 parameter
775 - added smoothing of volume changes caused by control change
776 messages
777 - sample loop parameters are now taken from the DimensionRegion
778 instead of the wave chunk
779 - fixed keyswitching for v3 gigs with a number of keyswitch splits
780 not equal to a power of two
781 - reimplementation of the filter algorithm. The new filter is more
782 accurate and supports all gig filter types, including bandreject
783 and lowpass turbo.
784 - real support for 24 bit samples - samples are not truncated to
785 16 bits anymore
786 - support for aftertouch (channel pressure, not polyphonic
787 aftertouch)
788 - LFO1 behaviour fixed (dampening from max volume instead of
789 amplifying from 0)
790
791 * LSCP server:
792 - fixed application exit on broken pipe error (fixes bug #20)
793 - fixed the notification messages delay due to lack of
794 network activity (fixes bug #26)
795 - fixed parser bug which occured on space(s) within device parameters
796 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
797
798 * audio driver:
799 - added aRts audio output driver (by no means RT safe)
800
801 * MIDI driver:
802 - fixed legacy sysex code which caused dispatching of MIDI SysEx
803 messages several times instead of once
804 - API extension for MIDI drivers which already supply exact time stamps
805 for events (i.e. for offline rendering based MIDI drivers)
806 - added checks for bad MIDI data
807
808 * linuxsampler application:
809 - show available sampler engine types on startup
810
811 * general changes:
812 - support for muting sampler channels and solo mode of the same, two new
813 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
814 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
815 introduced for this, the behavior is the same like on a mixer console
816 (patch by Grigor Iliev, a bit adjusted). Also added configure option
817 --enable-process-muted-channels which can be used to enable the
818 processing of muted channels.
819 - support for sostenuto pedal
820 - support for monitoring the total number of active voices
821 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
822 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
823 - fixed some memory management errors
824 - fixed some concurrency problems that could lead to crashes when
825 LSCP commands were executed
826 - fixed crash when instrument loading failed previously on the same
827 sampler channel (fixes bug #36)
828
829 Version 0.3.3 (15 July 2005)
830
831 * packaging changes:
832 - fixed compilation with gcc 4.0
833
834 * Gigasampler format engine:
835 - LFO preprocessing was performed even though the respective LFO was
836 disabled by the instrument patch (minor efficiency fix)
837 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
838 for volume ramp downs in the same fragment (needed for current voice
839 stealing implementation) then simply inform the user with a warning
840 about possible click sounds and reduce the volume ramp down
841 appropriately instead of cancelling the audio device connection
842
843 Version 0.3.2 (24 June 2005)
844
845 * packaging changes:
846 - updated autotools build files to compile on OS X
847 (conditional compilation of CoreMIDI and MidiShare drivers)
848 - hand-crafted assembly optimization code can be disabled with
849 './configure --disable-asm' (definitely not recommended)
850 - fixed 'make dist' rule to include all necessary files
851 - require automake (>= 1.5) for 'make -f Makefile.cvs'
852 (due to 'dist-bzip2' automake option)
853
854 * Gigasampler format engine:
855 - support for the gig parameters for "release velocity response" curves
856 - fine tuning of the EGADSR envelope
857 - volume of release triggered samples now depends on note-on velocity,
858 note length and gig parameter "release trigger decay" instead of
859 note-off velocity.
860 - revised voice stealing
861 (fixes crash and endless loop caused by voice stealing)
862 - don't reset scale tuning on instrument or audio output device change
863 - handle key group conflicts right at the beginning of each fragment
864 instead of when the respective voice is actually launched
865 (fixes undefined behavior if stolen voices belonged to a key group -
866 this case was followed by a "killed voice survived" error message)
867 - fixed minor issue with null/silence samples
868 (those stole voices even though they don't need a voice at all which
869 resulted in "voice stealing didn't work out" messages)
870 - don't reset volume, pan, pitch and MIDI controller values on
871 instrument or audio output device change
872
873 * LSCP server:
874 - fixed some crashes (patch by Grigor Iliev, fixes #19)
875 - fixed LSCP event "CHANNEL_INFO" notification
876 (e.g. did not notify on volume changes or MIDI program change events)
877
878 * linuxsampler application:
879 - added command line parameters --lscp-addr and --lscp-port to override
880 default IP address and port of LSCP server
881
882 Version 0.3.1 (24 May 2005)
883
884 * initial release
