* bugfix: instrument loading crashed for sfz and sf2 in Ardour (#176)
* more thread safety fixes for the instrument loading thread

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
45 - experimental support for per voice equalization
46 - added command line option --exec-after-init
47
48 * Gigasampler format engine:
49 - implemented the "round robin keyboard" dimension
50 - fixed round robin and random dimensions for cases when number of
51 dimension zones is not a power of two
52 - made round robin use a counter for each region instead of each
53 key
54
55 * SFZ format engine:
56 - Initial implementation (not usable yet)
57 - added support for v2 multiple stage envelope generators

59 one from the gig engine
60 - fixed memory leak and memory handling errors
61 - added support for trigger=first, trigger=legato and sw_previous
62 - allow non-numerical key values ("C#4" for example)
63 - "key" opcode now sets pitch_keycenter too
64 - fixed error when unloading instrument with same sample used by
65 multiple regions

302 - bugfix: calling SET VOICES (which Fantasia does on start and
303 refresh) could cause instruments to be unloaded
304 - Mac OS X: fixed name collision of enum in EffectControl and
305 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
306 - Mac OS X: fixed hanging threads
307 - Windows: disabled the previous thread fix on non-Mac systems, as
308 it caused hanging threads on Windows

310 after MIDI/audio device creation failure
311 - When creating MIDI instrument map entries with "PERSISTENT" type, the
312 instruments were uselessly precached with zero samples, however it still
313 took the full preloading time and on 1st program change the respective
314 instrument was completely reloaded again.
315 - fixed handling of rapid bank select and program change messages
316 sent to the same sampler channel (patch from the Open Octave
317 project, slightly adjusted)

328 Version 1.0.0 (31 July 2009)
329
330 * packaging changes:

333 "./configure --disable-jack-driver" was used
334 (patch by Alexis Ballier)
335 - fixed compilation with gcc 4.3
336 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
337 - fixed configure so it detects x86_64 (#107)
338 - fixes for building with newer MinGW versions
339 - fix for building with bison 2.4 (#111)
340 - fixed building with libgig installed in a non-standard directory
341 - minor fix in configure for mmsystem.h detection on MinGW
342 - Windows: look for editor plugins and Fantasia using base
343 directory of liblinuxsampler dll (look in the same directory and one
344 directory above)
345 - configure script fix: removed unconditional use of SSE
346 - fixed building with sqlite installed in a non-standard directory
347 - when cross-compiling, don't try to create instruments.db
348 - fix for new mingw-w64 version, which has usleep
349
350 * general changes:
351 - bugfix: on some POSIX systems instrument editor plugins refused to
352 load as we used a non-portable Linux specific struct field
353 (fixes bug #70, patch by Ronald Baljeu)
354 - fixed endless loop which occured when loading an instrument editor
355 plugin DLL on Windows systems failed
356 - fixed memory leaks that occurred when liblinuxsampler was unloaded
357 - optimized the SynchronizedConfig class so it doesn't wait
358 unnecessarily long after an update
359 - added support for notifying instrument editors on note-on / note-off
360 events (e.g. to highlight the pressed keys on the virtual keyboard
361 of gigedit)
362 - added support for triggering notes by instrument editors (see above)
363 - be verbose on DLL load errors (on Linux)
364 - fixed di-harmonic triangle LFO implementation (this LFO implementation
365 is only used by very few systems, most pick the int math
366 implementation, which is usually faster)
367 - fixes for audio drivers with varying buffer sizes
368 - experimental support for running LinuxSampler as a DSSI, LV2 and
369 VST plugin
370 - notification events for stream/voice count statistics are now sent
371 only when there are actual changes

373 multi-core and multi-cpu systems
374 - maximum voices and disk streams can now be altered at runtime
375 - fixed CPU feature detection on x86_64 (maybe fixes #108)
376 - automatic stacktrace mechanism is now turned off by default and can
377 be switched on by command line option "--stacktrace" (the automatic
378 stacktrace mechanism seems to be broken on most systems at the moment)
379 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
380 a pointer to the launched InstrumentEditor object
381 - added optional 3rd party user data parameter for following
382 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
383 InstrumentEditor::Launch(),
384 InstrumentManager::LaunchInstrumentEditor()
385 - theoretical fix: made SynchronizedConfig follow C++0x memory
386 model more strictly
387 - fixes for using large audio device buffers
388 - Windows: add the installation directory to the DLL search path
389 when loading an editor plugin (solves problems with VST and
390 gigedit on systems with other GTK versions installed)
391
392 * audio driver:
393 - removed the nonsense audio channel constraint (which was hard coded to
394 max. 100 audio channels) for most audio drivers
395 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
396 opposed to the LSCP specs
397 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
398 reflected the wrong value
399 - fixed a memory management bug in ASIO driver
400 - Makefile fix: JACK_CFLAGS wasn't used
401 - JACK: use jack_client_open instead of the deprecated
402 jack_client_new

405 previous binary release but accidentally never committed to CVS
406 (fixes #117)

408 win64)
409 - VST: added support for sample rate and buffer size changes
410 - VST: close editor (Fantasia) when the VST is removed
411 - VST: avoid opening Fantasia more than once for each VST instance
412 - VST: export main function as "main" on Linux too (fix for
413 energyXT)
414 - VST: changed number of output channels from one stereo to 16
415 stereo
416 - added channel routing, fxsends and midi maps to the settings
417 stored in the plugin state
418 - performance optimization of AudioChannel::MixTo() and
419 AudioChannel::CopyTo() methods using GCC vector exensions
420 (if available)
421 - ASIO fixes: avoid initializing the device twice, avoid throwing
422 exception when getting parameters from a disconnected device
423
424 * MIDI driver:
425 - added JACK MIDI driver
426 - dispatch bank select as ordinary CC as well, the user might seriously
427 want to (mis)use it for some purpose ("fixed" in all current MIDI
428 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
429 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
430 CoreMidi or AU
431 - fixed mingw-w64 compilation error in MME driver
432 - made program change handling in MIDI thread real-time safe by
433 moving the logic to a non-RT thread
434 - fixed minor memory leak in ALSA driver
435
436 * instruments database:
437 - avoid time consuming samples scanning when adding instruments
438 to the instruments database
439 - added support for handling lost files in the instruments database
440 - Implemented option for adding instruments in separate directories
441 in the instruments database
442 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
443 - work-around for missing fnmatch function on Windows to make
444 instrument database compilable
445 - added instrument database support on Windows
446 works with both standalone mode and VST plugin.
447 the instruments DB file is located in
448 %USERPROFILE%\.linuxsampler\instruments.db which allows different
449 databases for each windows user
450 if no DB is present it automatically creates the .linuxsampler subdir
451 and then creates an empty DB
452 - fixed recursive import, which was broken on Windows
453
454 * Gigasampler format engine:
455 - fixed a memory leak that could happen when a channel was deleted
456 while notes were playing
457 - made it possible to load an instrument even if the audio thread
458 isn't running
459 - added partial support for the "Controller Triggered" MIDI rule,
460 enough for piano gigs with pedal noise samples
461 - minor fix: only mark FX sends as being modified if really the
462 respective FX send MIDI controller was used
463 - added support for GM global device volume SysEx message
464 (can be selected at compile time to either apply globally to the
465 whole sampler [default] or only to the sampler channels that are
466 connected to the respective MIDI input port the SysEx message arrived
467 on)
468 - bugfix: notes triggered at position 0 in the audio buffer were
469 sometimes wrongly killed in the same buffer, causing no sound to
470 be played
471 - added support for chromatic / drumkit mode Roland GS Sysex message
472 which is usally used to switch a part between chromatic sounds and
473 drumkit sounds (as opposed to their common default setting of MIDI
474 part 10 being a drumkit part and all other ones chromatic parts), in
475 LS however one can switch between the first 16 MIDI instrument maps
476 defined for the sampler
477 - made it possible to create multiple sample channels even if the
478 audio thread isn't running
479 - fixed crash when removing channel with active voices (#116)
480 - bugfix: on sample reference changes (instrument editor), only
481 un-cache the respective sample if it's really not used by any
482 sampler engine anymore
483 - re-cache samples in case they were changed by an instrument editor,
484 e.g. when a sample was added while playing (#82)
485 - fixed hanging notes which occured when note-off event had the exact
486 same time stamp as the voice's note-on event and occured both in the
487 same audio fragment cycle (fixes bug #112)
488 - added support for the "fine tune" and "pitch bend range"
489 instrument-level gig parameters
490 - fixed minor artifacts in pitch bend handling
491 - added support for GS Reset SysEx message
492 - allow gig files to use unlimited downward pitch shifting
493 - added a limit check for upward pitch shifting
494 - bugfix: sometimes, when playing a note twice fast, the second
495 note was silent
496 - fixed crash happening when a pitch bend event arrived at the
497 same time a new instrument was loading
498
499 * LSCP server:
500 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
501 react on MIDI data arriving on certain sampler channels (so far only
502 Note-On and Note-Off events are sent via this LSCP event)
503 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
504 react on MIDI data arriving on certain MIDI input devices (so far only
505 Note-On and Note-Off events are sent via this LSCP event)
506 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
507 SET DB_INSTRUMENT FILE_PATH
508 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
509 frontends to send MIDI messages to specific sampler channel
510 - added two additional fields to GET FILE INSTRUMENT INFO command -
511 KEY_BINDINGS and KEYSWITCH_BINDINGS
512 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
513 was incorrect
514 - Optimized the retrieval of the MIDI instrument mappings
515 - added new LSCP command "SET VOICES" to globally alter the maximum
516 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
517 be triggered respectively
518 - added new LSCP command "SET STREAMS" to globally alter the maximum
519 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
520 which will be triggered respectively
521 - bugfix: retry if "select" returns EINTR (this fixes a crash when
522 a gigedit file dialog is opened)
523 - close all connections when LSCPServer is deleted
524 - hard close of all sockets on exit
525 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
526 driver
527
528 * Bug fixes:
529 - fixed a crash which occurs when removing a sampler channel waiting
530 to start instrument loading after another channel
531 - fixed a crash which occurs when removing a sampler channel with
532 instrument loading in progress (bug #113)
533 - fixed termination caused by uncaught exception when adding MIDI
534 instrument with PERSISTENT load mode
535 - fixed possible iterator invalidations when resetting the sampler
536 - fixed memory leaks when issuing the following LSCP commands:
537 GET AUDIO_OUTPUT_DRIVER INFO
538 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
539 GET MIDI_INPUT_DRIVER INFO
540 GET MIDI_INPUT_DRIVER_PARAMETER INFO
541 - fixed possible compilation error when sqlite is not present
542 - fixed orphaned pointers when setting maximum voices limit (bug #118)
543 - fixed crash when changing the audio output device of a sampler
544 channel with loaded instrument and start playing notes
545 - fixed endless loop in Engine::SuspendAll() (bug #120)
546 - fixed a low-level atomic load function that was broken on 64-bit
547 PowerPC, which probably could cause crashes on that platform
548 - fixed a memory management error which could cause a crash when a
549 plugin was unloaded
550 - bugfix: two private structs had the same name, which could cause
551 problems if the linker chose the wrong constructor
552 - fixed low-level ConditionServer usage bug that caused lockups on
553 Windows
554
555
556 Version 0.5.1 (6 December 2007)
557
558 * packaging changes:
559 - added autoconf checks for pthread library
560 - added autoconf check for pthread bug found on certain NPTL-enabled
561 glibc versions (see Gentoo bug report #194076)
562 - added autoconf checks for MS Windows
563
564 * general changes:
565 - bugfix: the thread used by an editor plugin didn't die when the
566 editor closed
567 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
568 out all the space. operator--() did not apply size_mask after
569 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
570 order to avoid problems with the _NonVolatileReader functions.
571 - bugfix: Stream.h: added a missing divide by BytesPerSample in
572 GetWriteSpace(). Since this function is currently only used in
573 the stream's qsort() compare function, it didn't trigger any
574 bugs.
575 - Resampler.h, Synthesizer.h: cubic interpolation now works in
576 24bit mode too. Faster method to read 24bit words on little
577 endian machines (x86): replaced 3 byte reads + shifts with a 1
578 unaligned 32bit read and shift
579 - experimental support for MS Windows (MIDI input via MME, AUDIO
580 output via ASIO)
581 - made handling of SIGINT signal (Ctrl-C) a bit more robust
582 - support for monitoring the total number of active disk streams
583 (new LSCP commands: GET TOTAL_STREAM_COUNT,
584 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
585
586 * AUDIO driver:
587 - added Windows ASIO low latency audio driver
588
589 * MIDI driver:
590 - added MME Windows MIDI driver
591
592 * LSCP server:
593 - added support for Windows style path / filenames, however with
594 forward slash path separators instead of backslash
595 (i.e. "C:/foo/bar.gig")
596 - allow naughty liblscp to send non-string device parameters within
597 apostrophes as well
598 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
599 "LIST FILE INSTRUMENTS <file>" and
600 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
601 about an arbitrary instrument file on the system where the sampler is
602 running on
603
604 Version 0.5.0 (15 October 2007)
605
606 * packaging changes:
607 - config.h is not going to be installed along with liblinuxsampler's
608 API header files anymore
609 - only the API relevant header (and source) files will be exported to
610 the Doxygen API documentation (explicitly listed in Doxyfile.in)
611 - added completely new XCode project files for Mac OSX which is now
612 capable to execute our autoconf environment, thus no need anymore
613 to maintain the compile time configuration file (osx/version.h) for
614 OSX manually (patch by Toshi Nagata)
615 - fixed buggy boolean --enable-foo / --disable-foo configure script
616 parameters
617 - global.h now only covers global definitions that are needed for the
618 C++ API header files, all implementation internal global definitions
619 are now in global_private.h
620 - atomic.h is not exposed to the C++ API anymore
621 - no need to include config.h anymore for using LS's API header files
622 - fixed warnings in API doc generation
623
624 * general changes:
625 - replaced the old, confusing MIDI program change mechanism by a
626 flexible MIDI instrument mapper which allows to map arbitrary
627 (MIDI bank, MIDI program) pairs with arbitrary
628 (engine type, instrument file, file index) triplets which will be
629 loaded on the respective channel when such MIDI program change
630 messages arrive, beside that, each entry allows to define a life-time
631 strategy for the instrument, so the user can define whether the
632 instrument should i.e. be permanently loaded (to be able to switch
633 quickly among sounds) or i.e. loaded just on demand when the
634 respective program change arrives (to safe RAM space), as well as a
635 global volume factor for each entry, so the user can adjust the volume
636 dynamic of his mapped instrument collection without having to modify
637 the instrument files, also one can manage arbitrary amount of such
638 MIDI instrument maps and assign each sampler channel individually
639 a certain map, so that i.e. separation of normal instruments and
640 drumkits is possible
641 - new notification events for tracking changes to audio/MIDI devices,
642 MIDI instrument maps, MIDI instruments, FX sends, global volume.
643 - sampler was limited to load max. 200 instruments in the background
644 due to a constant size RingBuffer FIFO which is now replaced by a
645 dynamic (unlimited) size std::list FIFO
646 - added FX sends, these allow to route audio signals to arbitrary audio
647 output channels for being processed by external effect processors
648 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
649 controllers
650 - global (sampler wide) volume can now be controlled at runtime
651 - Implemented new, improved notification system
652 - fixed compilation errors regarding OSX
653 (patch by Toshi Nagata)
654 - implemented instruments database
655 - added support for escape sequences to the instruments database
656 - added highly experimental support for on-the-fly instrument editing
657 within the sampler's process (by using instrument editor plugins),
658 you'll notice the new "Registered instrument editors:" message on
659 startup, added a new LSCP command:
660 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
661 to spawn a matching instrument editor for the instrument on the
662 given sampler channel, the plugin path can be overridden at compile
663 time with ./configure --enable-plugin-dir=/some/dir
664 - added experimental code for synchronizing instrument editors hosted
665 in the sampler's process to safely edit instruments while playing
666 without a crash (hopefully) by either suspending single regions
667 wherever possible or if unavoidable whole engine(s)
668 - fixed several issues in fundamental "Thread" class: set scheduling
669 policy and priority on thread level, set a minimum stack size for
670 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
671 threads simply inherited properties of starting thread instead of
672 setting their own policy and priority
673 - minor fix in our automatic stack trace mechanism on crashes, the
674 main process did not wait for the stack trace process to finish
675 its output
676 - fixed some minor memory leaks
677 - reenabled assembly features support, at the moment only for
678 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
679 - minor assembly fix in x86 features detection (don't use the PIC
680 register, to avoid relocations in the text segment at runtime)
681 - POSIX callback functions of Thread.h are hidden
682
683 * MIDI driver:
684 - dispatch bank select (MSB and LSB) messages
685
686 * audio driver:
687 - the ALSA audio output driver parameters now reflect the correct
688 parameter value ranges for the respective selected sound card
689 (patch by Till Wimmer, a bit fixed and extended)
690
691 * Gigasampler format engine:
692 - if a filter is used and EG2 finishes before EG1, let the voice
693 die when EG2 has finished (this fixes a problem with clicks and
694 voice starvation for some gigs)
695 - playback is no longer disabled during instrument loading
696 - all notes playing on a channel that changes its instrument keep
697 playing with the old instrument until they get a note off
698 command
699 - EG fix: a release value of zero could cause noises or crash
700 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
701 - EG fine tuning: when attack is zero the EG starts at a level
702 above max sustain level, which means that there is a decay phase
703 even if sustain is 100%
704 - more EG fixes: the level could sometimes go below zero and cause
705 noises or crashes
706 - minor fix of EGDecay (patch by Toshi Nagata)
707 - fixed compiler error when --enable-override-filter-type was
708 supplied to the configure script (fixes #46)
709 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
710 instead of a fix value
711 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
712 127 (solo mode) only kill voices if the respective mode really
713 changed
714
715 * LSCP server:
716 - fixed compile time error for old Bison versions
717 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
718 - parser now supports extended ASCII character set
719 (up to ASCII code 255, i.e. includes now umlauts and accents)
720 - filename arguments in LSCP commands now allow to use escape
721 sequences, that is directly literal as one of: \', \", \\, \n, \r,
722 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
723 code value like \xf2) (fixes bug #24)
724 - the following LSCP commands now also support escape sequences for at
725 least one of their text-based parameters (i.e. name, description):
726 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
727 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
728 "SET DB_INSTRUMENT_DIRECTORY NAME",
729 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
730 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
731 "FIND DB_INSTRUMENT_DIRECTORIES"
732 - returns verbose syntax errors (line and column where syntax error
733 occured, the unexpected character and the actually expected, possible
734 character(s), the latter only if less than 5 possibilities)
735 - made sure that LSCP syntax is not affected by gigedit locale
736 settings
737 - bugfix regarding strings parameter lists: all comma separated lists
738 of strings were treated as being one string containing commas
739 (fixes #57)
740
741 * Bug fixes:
742 - fixed crash occurring on certain LSCP scripts (Bug 39)
743 - another thread safety fix for lscp "load engine" and "set
744 channel audio output device"
745 - fixed a crash which occurs when reassigning the same engine
746 on a sampler channel with connected MIDI device
747 - fixed a crash which occurs when changing the number of ports of a MIDI
748 device connected to a sampler channel to number less then or equal
749 to the index of the port to which the sampler channel is connected.
750 - The previous bindings were not been disconnected when altering
751 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
752 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
753 - The active stream/voice count statistic was incorrect.
754 - notification events were not been sent for some sampler
755 channel changes
756 - added default min and max values to restrict the number of allowed
757 audio output channels and MIDI input ports
758 - the connection to the PCM interface is now closed when destroying
759 an audio output device
760 - files with slash in their path or filename could not be loaded
761
762 * test cases:
763 - updated and fixed (haven't been touched in a while)
764
765 Version 0.4.0 (24 November 2006)
766
767 * packaging changes:
768 - changed deprecated copyright attribute to license; added ldconfig
769 to post-(un)install steps; added devel package for liblinuxsampler;
770 to linuxsampler.spec (RPM)
771 - install necessary development header files for allowing 3rd party
772 applications to link against liblinuxsampler
773 - liblinuxsampler's API documentation can be generated with 'make docs'
774 (Doxygen required)
775 - added benchmark to automatically detect the best triangle LFO
776 implementation (currently either an integer math solution or a
777 di-harmonic approximation), automatic detection can be overriden
778 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
779 configure script argument though (mandatory for cross-compilation)
780 - do not automatically pick optimized gcc flags if the user already
781 provided some on his own (as CXXFLAGS)
782 - added compile time option to disable processing of All-Notes-Off MIDI
783 messages
784 - added compile time options to allow disabling the various audio and
785 MIDI drivers
786 - fixed automatic GCC CPU switch detection on PPC
787 (patch by Ebrahim Mayat)
788
789 * Gigasampler format engine:
790 - extensive synthesis optimization
791 (reimplementation of EGs and LFO(s), removed synthesis parameter
792 prerendering and the synthesis parameter matrix in general, splitting
793 each audio fragment into subfragments now where each subfragment uses
794 constant pitch and filter coefficients. The volume coefficient is
795 linearly interpolated inside a subfragment, unless
796 --disable-interpolate-volume is set.)
797 - fine tuning of the EG modulation parameters
798 - improved filter cutoff calculation by adding support for the
799 following gig parameters: Cutoff freq (used when no cutoff
800 controller is defined), Control invert, Minimum cutoff, Velocity
801 curve and Velocity range. The keyboard tracking now scales
802 cutoff frequency instead of resonance.
803 - added support for gig parameter Resonance.
804 - fixed bug in sysex handling (patch by Juan Linietsky)
805 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
806 which can be overridden with --enable-global-attenuation
807 - EG fixes: made the length of "attack hold" stage more
808 accurate. Release stage can now start before attack stage
809 ends. Cancel release didn't work when sustain was zero. Attack
810 time now has a minimal value to prevent clicks.
811 - fixed pitch changes larger than one octave
812 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
813 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
814 all modes can be altered via standard GM messages, that is CC5 for
815 altering portamento time, CC65 for enabling / disabling portamento
816 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
817 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
818 parameter) and crossfade
819 - added support for the "attenuation controller threshold" gig
820 parameter
821 - added smoothing of volume changes caused by control change
822 messages
823 - sample loop parameters are now taken from the DimensionRegion
824 instead of the wave chunk
825 - fixed keyswitching for v3 gigs with a number of keyswitch splits
826 not equal to a power of two
827 - reimplementation of the filter algorithm. The new filter is more
828 accurate and supports all gig filter types, including bandreject
829 and lowpass turbo.
830 - real support for 24 bit samples - samples are not truncated to
831 16 bits anymore
832 - support for aftertouch (channel pressure, not polyphonic
833 aftertouch)
834 - LFO1 behaviour fixed (dampening from max volume instead of
835 amplifying from 0)
836
837 * LSCP server:
838 - fixed application exit on broken pipe error (fixes bug #20)
839 - fixed the notification messages delay due to lack of
840 network activity (fixes bug #26)
841 - fixed parser bug which occured on space(s) within device parameters
842 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
843
844 * audio driver:
845 - added aRts audio output driver (by no means RT safe)
846
847 * MIDI driver:
848 - fixed legacy sysex code which caused dispatching of MIDI SysEx
849 messages several times instead of once
850 - API extension for MIDI drivers which already supply exact time stamps
851 for events (i.e. for offline rendering based MIDI drivers)
852 - added checks for bad MIDI data
853
854 * linuxsampler application:
855 - show available sampler engine types on startup
856
857 * general changes:
858 - support for muting sampler channels and solo mode of the same, two new
859 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
860 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
861 introduced for this, the behavior is the same like on a mixer console
862 (patch by Grigor Iliev, a bit adjusted). Also added configure option
863 --enable-process-muted-channels which can be used to enable the
864 processing of muted channels.
865 - support for sostenuto pedal
866 - support for monitoring the total number of active voices
867 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
868 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
869 - fixed some memory management errors
870 - fixed some concurrency problems that could lead to crashes when
871 LSCP commands were executed
872 - fixed crash when instrument loading failed previously on the same
873 sampler channel (fixes bug #36)
874
875 Version 0.3.3 (15 July 2005)
876
877 * packaging changes:
878 - fixed compilation with gcc 4.0
879
880 * Gigasampler format engine:
881 - LFO preprocessing was performed even though the respective LFO was
882 disabled by the instrument patch (minor efficiency fix)
883 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
884 for volume ramp downs in the same fragment (needed for current voice
885 stealing implementation) then simply inform the user with a warning
886 about possible click sounds and reduce the volume ramp down
887 appropriately instead of cancelling the audio device connection
888
889 Version 0.3.2 (24 June 2005)
890
891 * packaging changes:
892 - updated autotools build files to compile on OS X
893 (conditional compilation of CoreMIDI and MidiShare drivers)
894 - hand-crafted assembly optimization code can be disabled with
895 './configure --disable-asm' (definitely not recommended)
896 - fixed 'make dist' rule to include all necessary files
897 - require automake (>= 1.5) for 'make -f Makefile.cvs'
898 (due to 'dist-bzip2' automake option)
899
900 * Gigasampler format engine:
901 - support for the gig parameters for "release velocity response" curves
902 - fine tuning of the EGADSR envelope
903 - volume of release triggered samples now depends on note-on velocity,
904 note length and gig parameter "release trigger decay" instead of
905 note-off velocity.
906 - revised voice stealing
907 (fixes crash and endless loop caused by voice stealing)
908 - don't reset scale tuning on instrument or audio output device change
909 - handle key group conflicts right at the beginning of each fragment
910 instead of when the respective voice is actually launched
911 (fixes undefined behavior if stolen voices belonged to a key group -
912 this case was followed by a "killed voice survived" error message)
913 - fixed minor issue with null/silence samples
914 (those stole voices even though they don't need a voice at all which
915 resulted in "voice stealing didn't work out" messages)
916 - don't reset volume, pan, pitch and MIDI controller values on
917 instrument or audio output device change
918
919 * LSCP server:
920 - fixed some crashes (patch by Grigor Iliev, fixes #19)
921 - fixed LSCP event "CHANNEL_INFO" notification
922 (e.g. did not notify on volume changes or MIDI program change events)
923
