* fixed bug #162

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 "state" extension 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
27 - Introduced support for optional environment variable
28 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
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
40 effect type is)
41 - implemented support for internal LADSPA effects
42 - raised limit of program change queue from 100 to 512
43 (as suggested by Alex Stone)
44 - implemented sine LFO, pulse LFO and saw LFO

278 channel to a different engine type
279 - fixed crash when deleting a sampler channel or changing engine
280 type while an instrument load was in progress
281 - bugfix: playing a note while changing the instrument could cause
282 a crash, or give "Handing back unknown region" error messages
283 - bugfix: calling SET VOICES (which Fantasia does on start and
284 refresh) could cause instruments to be unloaded
285 - Mac OS X: fixed name collision of enum in EffectControl and
286 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
287 - Mac OS X: fixed hanging threads
288 - Windows: disabled the previous thread fix on non-Mac systems, as
289 it caused hanging threads on Windows
290 - Fixed possible crashes due to corrupted MIDI/audio device list
291 after MIDI/audio device creation failure
292 - When creating MIDI instrument map entries with "PERSISTENT" type, the
293 instruments were uselessly precached with zero samples, however it still
294 took the full preloading time and on 1st program change the respective
295 instrument was completely reloaded again.
296 - fixed handling of rapid bank select and program change messages
297 sent to the same sampler channel (patch from the Open Octave
298 project, slightly adjusted)
299 - fixed crash when trying to create an effect instance with controls
300 which min and/or max values depend on the sample rate
301 - fixed bug #162
302
303 Version 1.0.0 (31 July 2009)
304
305 * packaging changes:
306 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
307 causing e.g. the libgig test to fail when
308 "./configure --disable-jack-driver" was used

315 - fixed building with libgig installed in a non-standard directory
316 - minor fix in configure for mmsystem.h detection on MinGW
317 - Windows: look for editor plugins and Fantasia using base
318 directory of liblinuxsampler dll (look in the same directory and one
319 directory above)
320 - configure script fix: removed unconditional use of SSE
321 - fixed building with sqlite installed in a non-standard directory
322 - when cross-compiling, don't try to create instruments.db
323 - fix for new mingw-w64 version, which has usleep
324
325 * general changes:
326 - bugfix: on some POSIX systems instrument editor plugins refused to
327 load as we used a non-portable Linux specific struct field
328 (fixes bug #70, patch by Ronald Baljeu)
329 - fixed endless loop which occured when loading an instrument editor
330 plugin DLL on Windows systems failed
331 - fixed memory leaks that occurred when liblinuxsampler was unloaded
332 - optimized the SynchronizedConfig class so it doesn't wait
333 unnecessarily long after an update
334 - added support for notifying instrument editors on note-on / note-off
335 events (e.g. to highlight the pressed keys on the virtual keyboard
336 of gigedit)
337 - added support for triggering notes by instrument editors (see above)
338 - be verbose on DLL load errors (on Linux)
339 - fixed di-harmonic triangle LFO implementation (this LFO implementation
340 is only used by very few systems, most pick the int math
341 implementation, which is usually faster)
342 - fixes for audio drivers with varying buffer sizes
343 - experimental support for running LinuxSampler as a DSSI, LV2 and
344 VST plugin
345 - notification events for stream/voice count statistics are now sent
346 only when there are actual changes
347 - added memory ordering constraints to improve stability on
348 multi-core and multi-cpu systems
349 - maximum voices and disk streams can now be altered at runtime
350 - fixed CPU feature detection on x86_64 (maybe fixes #108)
351 - automatic stacktrace mechanism is now turned off by default and can
352 be switched on by command line option "--stacktrace" (the automatic
353 stacktrace mechanism seems to be broken on most systems at the moment)
354 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
355 a pointer to the launched InstrumentEditor object
356 - added optional 3rd party user data parameter for following
357 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
358 InstrumentEditor::Launch(),
359 InstrumentManager::LaunchInstrumentEditor()
360 - theoretical fix: made SynchronizedConfig follow C++0x memory
361 model more strictly
362 - fixes for using large audio device buffers
363 - Windows: add the installation directory to the DLL search path
364 when loading an editor plugin (solves problems with VST and
365 gigedit on systems with other GTK versions installed)
366
367 * audio driver:
368 - removed the nonsense audio channel constraint (which was hard coded to
369 max. 100 audio channels) for most audio drivers
370 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
371 opposed to the LSCP specs
372 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
373 reflected the wrong value
374 - fixed a memory management bug in ASIO driver
375 - Makefile fix: JACK_CFLAGS wasn't used
376 - JACK: use jack_client_open instead of the deprecated
377 jack_client_new
378 - added (experimental) CoreAudio driver
379 - applied old fixes to the ASIO driver that were included in the
380 previous binary release but accidentally never committed to CVS
381 (fixes #117)
382 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
383 win64)
384 - VST: added support for sample rate and buffer size changes
385 - VST: close editor (Fantasia) when the VST is removed
386 - VST: avoid opening Fantasia more than once for each VST instance
387 - VST: export main function as "main" on Linux too (fix for
388 energyXT)
389 - VST: changed number of output channels from one stereo to 16
390 stereo
391 - added channel routing, fxsends and midi maps to the settings
392 stored in the plugin state
393 - performance optimization of AudioChannel::MixTo() and
394 AudioChannel::CopyTo() methods using GCC vector exensions
395 (if available)
396 - ASIO fixes: avoid initializing the device twice, avoid throwing
397 exception when getting parameters from a disconnected device
398
399 * MIDI driver:
400 - added JACK MIDI driver
401 - dispatch bank select as ordinary CC as well, the user might seriously
402 want to (mis)use it for some purpose ("fixed" in all current MIDI
403 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
404 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
405 CoreMidi or AU
406 - fixed mingw-w64 compilation error in MME driver
407 - made program change handling in MIDI thread real-time safe by
408 moving the logic to a non-RT thread
409 - fixed minor memory leak in ALSA driver
410
411 * instruments database:
412 - avoid time consuming samples scanning when adding instruments
413 to the instruments database

418 - work-around for missing fnmatch function on Windows to make
419 instrument database compilable
420 - added instrument database support on Windows
421 works with both standalone mode and VST plugin.
422 the instruments DB file is located in
423 %USERPROFILE%\.linuxsampler\instruments.db which allows different
424 databases for each windows user
425 if no DB is present it automatically creates the .linuxsampler subdir
426 and then creates an empty DB
427 - fixed recursive import, which was broken on Windows
428
429 * Gigasampler format engine:
430 - fixed a memory leak that could happen when a channel was deleted
431 while notes were playing
432 - made it possible to load an instrument even if the audio thread
433 isn't running
434 - added partial support for the "Controller Triggered" MIDI rule,
435 enough for piano gigs with pedal noise samples
436 - minor fix: only mark FX sends as being modified if really the
437 respective FX send MIDI controller was used
438 - added support for GM global device volume SysEx message
439 (can be selected at compile time to either apply globally to the
440 whole sampler [default] or only to the sampler channels that are
441 connected to the respective MIDI input port the SysEx message arrived
442 on)
443 - bugfix: notes triggered at position 0 in the audio buffer were
444 sometimes wrongly killed in the same buffer, causing no sound to
445 be played
446 - added support for chromatic / drumkit mode Roland GS Sysex message
447 which is usally used to switch a part between chromatic sounds and
448 drumkit sounds (as opposed to their common default setting of MIDI
449 part 10 being a drumkit part and all other ones chromatic parts), in
450 LS however one can switch between the first 16 MIDI instrument maps
451 defined for the sampler
452 - made it possible to create multiple sample channels even if the
453 audio thread isn't running
454 - fixed crash when removing channel with active voices (#116)
455 - bugfix: on sample reference changes (instrument editor), only
456 un-cache the respective sample if it's really not used by any
457 sampler engine anymore
458 - re-cache samples in case they were changed by an instrument editor,
459 e.g. when a sample was added while playing (#82)
460 - fixed hanging notes which occured when note-off event had the exact
461 same time stamp as the voice's note-on event and occured both in the
462 same audio fragment cycle (fixes bug #112)
463 - added support for the "fine tune" and "pitch bend range"
464 instrument-level gig parameters
465 - fixed minor artifacts in pitch bend handling
466 - added support for GS Reset SysEx message
467 - allow gig files to use unlimited downward pitch shifting
468 - added a limit check for upward pitch shifting
469 - bugfix: sometimes, when playing a note twice fast, the second
470 note was silent
471 - fixed crash happening when a pitch bend event arrived at the
472 same time a new instrument was loading
473
474 * LSCP server:
475 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
476 react on MIDI data arriving on certain sampler channels (so far only
477 Note-On and Note-Off events are sent via this LSCP event)
478 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
479 react on MIDI data arriving on certain MIDI input devices (so far only
480 Note-On and Note-Off events are sent via this LSCP event)
481 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
482 SET DB_INSTRUMENT FILE_PATH
483 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
484 frontends to send MIDI messages to specific sampler channel
485 - added two additional fields to GET FILE INSTRUMENT INFO command -
486 KEY_BINDINGS and KEYSWITCH_BINDINGS
487 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
488 was incorrect
489 - Optimized the retrieval of the MIDI instrument mappings
490 - added new LSCP command "SET VOICES" to globally alter the maximum
491 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
492 be triggered respectively
493 - added new LSCP command "SET STREAMS" to globally alter the maximum
494 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
495 which will be triggered respectively
496 - bugfix: retry if "select" returns EINTR (this fixes a crash when
497 a gigedit file dialog is opened)
498 - close all connections when LSCPServer is deleted
499 - hard close of all sockets on exit
500 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
501 driver
502
503 * Bug fixes:
504 - fixed a crash which occurs when removing a sampler channel waiting
505 to start instrument loading after another channel
506 - fixed a crash which occurs when removing a sampler channel with
507 instrument loading in progress (bug #113)
508 - fixed termination caused by uncaught exception when adding MIDI
509 instrument with PERSISTENT load mode
510 - fixed possible iterator invalidations when resetting the sampler
511 - fixed memory leaks when issuing the following LSCP commands:
512 GET AUDIO_OUTPUT_DRIVER INFO
513 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
514 GET MIDI_INPUT_DRIVER INFO
515 GET MIDI_INPUT_DRIVER_PARAMETER INFO
516 - fixed possible compilation error when sqlite is not present
517 - fixed orphaned pointers when setting maximum voices limit (bug #118)
518 - fixed crash when changing the audio output device of a sampler
519 channel with loaded instrument and start playing notes
520 - fixed endless loop in Engine::SuspendAll() (bug #120)
521 - fixed a low-level atomic load function that was broken on 64-bit
522 PowerPC, which probably could cause crashes on that platform
523 - fixed a memory management error which could cause a crash when a
524 plugin was unloaded
525 - bugfix: two private structs had the same name, which could cause
526 problems if the linker chose the wrong constructor
527 - fixed low-level ConditionServer usage bug that caused lockups on
528 Windows
529
530
531 Version 0.5.1 (6 December 2007)
532
533 * packaging changes:
534 - added autoconf checks for pthread library
535 - added autoconf check for pthread bug found on certain NPTL-enabled
536 glibc versions (see Gentoo bug report #194076)
537 - added autoconf checks for MS Windows
538
539 * general changes:
540 - bugfix: the thread used by an editor plugin didn't die when the
541 editor closed
542 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
543 out all the space. operator--() did not apply size_mask after
544 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
545 order to avoid problems with the _NonVolatileReader functions.
546 - bugfix: Stream.h: added a missing divide by BytesPerSample in
547 GetWriteSpace(). Since this function is currently only used in
548 the stream's qsort() compare function, it didn't trigger any
549 bugs.
550 - Resampler.h, Synthesizer.h: cubic interpolation now works in
551 24bit mode too. Faster method to read 24bit words on little
552 endian machines (x86): replaced 3 byte reads + shifts with a 1
553 unaligned 32bit read and shift
554 - experimental support for MS Windows (MIDI input via MME, AUDIO
555 output via ASIO)
556 - made handling of SIGINT signal (Ctrl-C) a bit more robust
557 - support for monitoring the total number of active disk streams
558 (new LSCP commands: GET TOTAL_STREAM_COUNT,
559 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
560
561 * AUDIO driver:
562 - added Windows ASIO low latency audio driver
563
564 * MIDI driver:
565 - added MME Windows MIDI driver
566
567 * LSCP server:
568 - added support for Windows style path / filenames, however with
569 forward slash path separators instead of backslash
570 (i.e. "C:/foo/bar.gig")
571 - allow naughty liblscp to send non-string device parameters within
572 apostrophes as well
573 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
574 "LIST FILE INSTRUMENTS <file>" and
575 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
576 about an arbitrary instrument file on the system where the sampler is
577 running on
578
579 Version 0.5.0 (15 October 2007)
580
581 * packaging changes:
582 - config.h is not going to be installed along with liblinuxsampler's
583 API header files anymore
584 - only the API relevant header (and source) files will be exported to
585 the Doxygen API documentation (explicitly listed in Doxyfile.in)
586 - added completely new XCode project files for Mac OSX which is now
587 capable to execute our autoconf environment, thus no need anymore
588 to maintain the compile time configuration file (osx/version.h) for
589 OSX manually (patch by Toshi Nagata)
590 - fixed buggy boolean --enable-foo / --disable-foo configure script
591 parameters
592 - global.h now only covers global definitions that are needed for the
593 C++ API header files, all implementation internal global definitions
594 are now in global_private.h
595 - atomic.h is not exposed to the C++ API anymore
596 - no need to include config.h anymore for using LS's API header files
597 - fixed warnings in API doc generation
598
599 * general changes:
600 - replaced the old, confusing MIDI program change mechanism by a
601 flexible MIDI instrument mapper which allows to map arbitrary
602 (MIDI bank, MIDI program) pairs with arbitrary
603 (engine type, instrument file, file index) triplets which will be
604 loaded on the respective channel when such MIDI program change
605 messages arrive, beside that, each entry allows to define a life-time
606 strategy for the instrument, so the user can define whether the
607 instrument should i.e. be permanently loaded (to be able to switch
608 quickly among sounds) or i.e. loaded just on demand when the
609 respective program change arrives (to safe RAM space), as well as a
610 global volume factor for each entry, so the user can adjust the volume
611 dynamic of his mapped instrument collection without having to modify
612 the instrument files, also one can manage arbitrary amount of such
613 MIDI instrument maps and assign each sampler channel individually
614 a certain map, so that i.e. separation of normal instruments and
615 drumkits is possible
616 - new notification events for tracking changes to audio/MIDI devices,
617 MIDI instrument maps, MIDI instruments, FX sends, global volume.
618 - sampler was limited to load max. 200 instruments in the background
619 due to a constant size RingBuffer FIFO which is now replaced by a
620 dynamic (unlimited) size std::list FIFO
621 - added FX sends, these allow to route audio signals to arbitrary audio
622 output channels for being processed by external effect processors
623 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
624 controllers
625 - global (sampler wide) volume can now be controlled at runtime
626 - Implemented new, improved notification system
627 - fixed compilation errors regarding OSX
628 (patch by Toshi Nagata)
629 - implemented instruments database
630 - added support for escape sequences to the instruments database
631 - added highly experimental support for on-the-fly instrument editing
632 within the sampler's process (by using instrument editor plugins),
633 you'll notice the new "Registered instrument editors:" message on
634 startup, added a new LSCP command:
635 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
636 to spawn a matching instrument editor for the instrument on the
637 given sampler channel, the plugin path can be overridden at compile
638 time with ./configure --enable-plugin-dir=/some/dir
639 - added experimental code for synchronizing instrument editors hosted
640 in the sampler's process to safely edit instruments while playing
641 without a crash (hopefully) by either suspending single regions
642 wherever possible or if unavoidable whole engine(s)
643 - fixed several issues in fundamental "Thread" class: set scheduling
644 policy and priority on thread level, set a minimum stack size for
645 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
646 threads simply inherited properties of starting thread instead of
647 setting their own policy and priority
648 - minor fix in our automatic stack trace mechanism on crashes, the
649 main process did not wait for the stack trace process to finish
650 its output
651 - fixed some minor memory leaks
652 - reenabled assembly features support, at the moment only for
653 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
654 - minor assembly fix in x86 features detection (don't use the PIC
655 register, to avoid relocations in the text segment at runtime)
656 - POSIX callback functions of Thread.h are hidden
657
658 * MIDI driver:
659 - dispatch bank select (MSB and LSB) messages
660
661 * audio driver:
662 - the ALSA audio output driver parameters now reflect the correct
663 parameter value ranges for the respective selected sound card
664 (patch by Till Wimmer, a bit fixed and extended)
665
666 * Gigasampler format engine:
667 - if a filter is used and EG2 finishes before EG1, let the voice
668 die when EG2 has finished (this fixes a problem with clicks and
669 voice starvation for some gigs)
670 - playback is no longer disabled during instrument loading
671 - all notes playing on a channel that changes its instrument keep
672 playing with the old instrument until they get a note off
673 command
674 - EG fix: a release value of zero could cause noises or crash
675 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
676 - EG fine tuning: when attack is zero the EG starts at a level
677 above max sustain level, which means that there is a decay phase
678 even if sustain is 100%
679 - more EG fixes: the level could sometimes go below zero and cause
680 noises or crashes
681 - minor fix of EGDecay (patch by Toshi Nagata)
682 - fixed compiler error when --enable-override-filter-type was
683 supplied to the configure script (fixes #46)
684 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
685 instead of a fix value
686 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
687 127 (solo mode) only kill voices if the respective mode really
688 changed
689
690 * LSCP server:
691 - fixed compile time error for old Bison versions
692 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
693 - parser now supports extended ASCII character set
694 (up to ASCII code 255, i.e. includes now umlauts and accents)
695 - filename arguments in LSCP commands now allow to use escape
696 sequences, that is directly literal as one of: \', \", \\, \n, \r,
697 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
698 code value like \xf2) (fixes bug #24)
699 - the following LSCP commands now also support escape sequences for at
700 least one of their text-based parameters (i.e. name, description):
701 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
702 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
703 "SET DB_INSTRUMENT_DIRECTORY NAME",
704 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
705 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
706 "FIND DB_INSTRUMENT_DIRECTORIES"
707 - returns verbose syntax errors (line and column where syntax error
708 occured, the unexpected character and the actually expected, possible
709 character(s), the latter only if less than 5 possibilities)
710 - made sure that LSCP syntax is not affected by gigedit locale
711 settings
712 - bugfix regarding strings parameter lists: all comma separated lists
713 of strings were treated as being one string containing commas
714 (fixes #57)
715
716 * Bug fixes:
717 - fixed crash occurring on certain LSCP scripts (Bug 39)
718 - another thread safety fix for lscp "load engine" and "set
719 channel audio output device"
720 - fixed a crash which occurs when reassigning the same engine
721 on a sampler channel with connected MIDI device
722 - fixed a crash which occurs when changing the number of ports of a MIDI
723 device connected to a sampler channel to number less then or equal
724 to the index of the port to which the sampler channel is connected.
725 - The previous bindings were not been disconnected when altering
726 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
727 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
728 - The active stream/voice count statistic was incorrect.
729 - notification events were not been sent for some sampler
730 channel changes
731 - added default min and max values to restrict the number of allowed
732 audio output channels and MIDI input ports
733 - the connection to the PCM interface is now closed when destroying
734 an audio output device
735 - files with slash in their path or filename could not be loaded
736
737 * test cases:
738 - updated and fixed (haven't been touched in a while)
739
740 Version 0.4.0 (24 November 2006)
741
742 * packaging changes:
743 - changed deprecated copyright attribute to license; added ldconfig
744 to post-(un)install steps; added devel package for liblinuxsampler;
745 to linuxsampler.spec (RPM)
746 - install necessary development header files for allowing 3rd party
747 applications to link against liblinuxsampler
748 - liblinuxsampler's API documentation can be generated with 'make docs'
749 (Doxygen required)
750 - added benchmark to automatically detect the best triangle LFO
751 implementation (currently either an integer math solution or a
752 di-harmonic approximation), automatic detection can be overriden
753 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
754 configure script argument though (mandatory for cross-compilation)
755 - do not automatically pick optimized gcc flags if the user already
756 provided some on his own (as CXXFLAGS)
757 - added compile time option to disable processing of All-Notes-Off MIDI
758 messages
759 - added compile time options to allow disabling the various audio and
760 MIDI drivers
761 - fixed automatic GCC CPU switch detection on PPC
762 (patch by Ebrahim Mayat)
763
764 * Gigasampler format engine:
765 - extensive synthesis optimization
766 (reimplementation of EGs and LFO(s), removed synthesis parameter
767 prerendering and the synthesis parameter matrix in general, splitting
768 each audio fragment into subfragments now where each subfragment uses
769 constant pitch and filter coefficients. The volume coefficient is
770 linearly interpolated inside a subfragment, unless
771 --disable-interpolate-volume is set.)
772 - fine tuning of the EG modulation parameters
773 - improved filter cutoff calculation by adding support for the
774 following gig parameters: Cutoff freq (used when no cutoff
775 controller is defined), Control invert, Minimum cutoff, Velocity
776 curve and Velocity range. The keyboard tracking now scales
777 cutoff frequency instead of resonance.
778 - added support for gig parameter Resonance.
779 - fixed bug in sysex handling (patch by Juan Linietsky)
780 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
781 which can be overridden with --enable-global-attenuation
782 - EG fixes: made the length of "attack hold" stage more
783 accurate. Release stage can now start before attack stage
784 ends. Cancel release didn't work when sustain was zero. Attack
785 time now has a minimal value to prevent clicks.
786 - fixed pitch changes larger than one octave
787 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
788 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
789 all modes can be altered via standard GM messages, that is CC5 for
790 altering portamento time, CC65 for enabling / disabling portamento
791 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
792 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
793 parameter) and crossfade
794 - added support for the "attenuation controller threshold" gig
795 parameter
796 - added smoothing of volume changes caused by control change
797 messages
798 - sample loop parameters are now taken from the DimensionRegion
799 instead of the wave chunk
800 - fixed keyswitching for v3 gigs with a number of keyswitch splits
801 not equal to a power of two
802 - reimplementation of the filter algorithm. The new filter is more
803 accurate and supports all gig filter types, including bandreject
804 and lowpass turbo.
805 - real support for 24 bit samples - samples are not truncated to
806 16 bits anymore
807 - support for aftertouch (channel pressure, not polyphonic
808 aftertouch)
809 - LFO1 behaviour fixed (dampening from max volume instead of
810 amplifying from 0)
811
812 * LSCP server:
813 - fixed application exit on broken pipe error (fixes bug #20)
814 - fixed the notification messages delay due to lack of
815 network activity (fixes bug #26)
816 - fixed parser bug which occured on space(s) within device parameters
817 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
818
819 * audio driver:
820 - added aRts audio output driver (by no means RT safe)
821
822 * MIDI driver:
823 - fixed legacy sysex code which caused dispatching of MIDI SysEx
824 messages several times instead of once
825 - API extension for MIDI drivers which already supply exact time stamps
826 for events (i.e. for offline rendering based MIDI drivers)
827 - added checks for bad MIDI data
828
829 * linuxsampler application:
830 - show available sampler engine types on startup
831
832 * general changes:
833 - support for muting sampler channels and solo mode of the same, two new
834 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
835 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
836 introduced for this, the behavior is the same like on a mixer console
837 (patch by Grigor Iliev, a bit adjusted). Also added configure option
838 --enable-process-muted-channels which can be used to enable the
839 processing of muted channels.
840 - support for sostenuto pedal
841 - support for monitoring the total number of active voices
842 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
843 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
844 - fixed some memory management errors
845 - fixed some concurrency problems that could lead to crashes when
846 LSCP commands were executed
847 - fixed crash when instrument loading failed previously on the same
848 sampler channel (fixes bug #36)
849
850 Version 0.3.3 (15 July 2005)
851
852 * packaging changes:
853 - fixed compilation with gcc 4.0
854
855 * Gigasampler format engine:
856 - LFO preprocessing was performed even though the respective LFO was
857 disabled by the instrument patch (minor efficiency fix)
858 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
859 for volume ramp downs in the same fragment (needed for current voice
860 stealing implementation) then simply inform the user with a warning
861 about possible click sounds and reduce the volume ramp down
862 appropriately instead of cancelling the audio device connection
863
864 Version 0.3.2 (24 June 2005)
865
866 * packaging changes:
867 - updated autotools build files to compile on OS X
868 (conditional compilation of CoreMIDI and MidiShare drivers)
869 - hand-crafted assembly optimization code can be disabled with
870 './configure --disable-asm' (definitely not recommended)
871 - fixed 'make dist' rule to include all necessary files
872 - require automake (>= 1.5) for 'make -f Makefile.cvs'
873 (due to 'dist-bzip2' automake option)
874
875 * Gigasampler format engine:
876 - support for the gig parameters for "release velocity response" curves
877 - fine tuning of the EGADSR envelope
878 - volume of release triggered samples now depends on note-on velocity,
879 note length and gig parameter "release trigger decay" instead of
880 note-off velocity.
881 - revised voice stealing
882 (fixes crash and endless loop caused by voice stealing)
883 - don't reset scale tuning on instrument or audio output device change
884 - handle key group conflicts right at the beginning of each fragment
885 instead of when the respective voice is actually launched
886 (fixes undefined behavior if stolen voices belonged to a key group -
887 this case was followed by a "killed voice survived" error message)
888 - fixed minor issue with null/silence samples
889 (those stole voices even though they don't need a voice at all which
890 resulted in "voice stealing didn't work out" messages)
891 - don't reset volume, pan, pitch and MIDI controller values on
892 instrument or audio output device change
893
894 * LSCP server:
895 - fixed some crashes (patch by Grigor Iliev, fixes #19)
896 - fixed LSCP event "CHANNEL_INFO" notification
897 (e.g. did not notify on volume changes or MIDI program change events)
898
899 * linuxsampler application:
900 - added command line parameters --lscp-addr and --lscp-port to override
901 default IP address and port of LSCP server
902
903 Version 0.3.1 (24 May 2005)
904
905 * initial release
