2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK
6 - Mac OS X: fixed building outside source directory
7 - made sure all source files for hostplugins are included when
8 doing "make dist"
9 - removed empty directories left from the cvs to svn migration
10 - fixed compilation with gcc 4.6.1
11 - another "make dist" fix, for the LV2 plugin
12 - made --enable-pthread-testcancel default on Mac OS X
13 - minor Makefile fix for building lscpparser when build and source
14 directories are separate
15 - Mac OS X: made it possible to specify plugin installation dir to
16 configure
17 - Mac OS X: Makefile fix for the install-strip target
18 - fixed compilation with gcc 4.7
19 - fixed configure script error with old autoconf versions
20 - lsatomic.h: use gcc provided atomic functions if building with
21 gcc 4.7 and C++11
22 - modernized configure script
23
24 * general changes:
25 - Refactoring: moved the independent code from
26 the Gigasampler format engine to base classes
27 - command line option '--profile' is currently disabled, since the
28 respective profiling code is currently broken
29 - Introduced support for optional environment variable
30 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
31 where the sampler shall look for instrument editor plugins
32 (patch by Luis Garrido, slightly modified).
33 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
34 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
35 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
36 note (in this implementation of the sampler its simply hard routed to
37 the 1st effect send of the sampler channel, no matter what the actual
38 effect type is)
39 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
40 note (in this implementation of the sampler its simply hard routed to
41 the 2nd effect send of the sampler channel, no matter what the actual
42 effect type is)
43 - implemented support for internal LADSPA effects
44 - raised limit of program change queue from 100 to 512
45 (as suggested by Alex Stone)
46 - implemented sine LFO, pulse LFO and saw LFO
47 - experimental support for per voice equalization
48 - added command line option --exec-after-init
49 - Introduced new C++ API method:
50 EngineChannel::InstrumentFileName(int index)
51 allowing to retrieve the whole list of files used for the loaded
52 instrument on an engine channel (a.k.a. part). Some GigaStudio
53 instruments for example are splitted over several files like
54 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
55 - Added new C++ API method Sampler::GetGlobalMaxVoices().
56 - Added new C++ API method Sampler::GetGlobalMaxStreams().

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

262 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
263 port and audio channel routing for DSSI plugins are now visible.
264 - LV2: use urid and atom extensions instead of deprecated uri-map
265 and event
266 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

283 to them a la JACK, via the usual sampler APIs
284 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
285 the driver will automatically connect to other CoreMIDI clients' ports
286 (e.g. external MIDI devices being attached to the Mac)
287
288 * audio driver:
289 - ASIO driver fixes for newer gcc versions (fix from PortAudio)

332 channel to a different engine type
333 - fixed crash when deleting a sampler channel or changing engine
334 type while an instrument load was in progress
335 - bugfix: playing a note while changing the instrument could cause
336 a crash, or give "Handing back unknown region" error messages
337 - bugfix: calling SET VOICES (which Fantasia does on start and
338 refresh) could cause instruments to be unloaded
339 - Mac OS X: fixed name collision of enum in EffectControl and
340 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
341 - Mac OS X: fixed hanging threads
342 - Windows: disabled the previous thread fix on non-Mac systems, as
343 it caused hanging threads on Windows
344 - Fixed possible crashes due to corrupted MIDI/audio device list
345 after MIDI/audio device creation failure
346 - When creating MIDI instrument map entries with "PERSISTENT" type, the
347 instruments were uselessly precached with zero samples, however it still
348 took the full preloading time and on 1st program change the respective
349 instrument was completely reloaded again.
350 - fixed handling of rapid bank select and program change messages
351 sent to the same sampler channel (patch from the Open Octave
352 project, slightly adjusted)
353 - fixed crash when trying to create an effect instance with controls
354 which min and/or max values depend on the sample rate

369 (labelled "Disk stream not available in time")
370
371 Version 1.0.0 (31 July 2009)
372
373 * packaging changes:
374 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

395 load as we used a non-portable Linux specific struct field
396 (fixes bug #70, patch by Ronald Baljeu)
397 - fixed endless loop which occured when loading an instrument editor
398 plugin DLL on Windows systems failed
399 - fixed memory leaks that occurred when liblinuxsampler was unloaded
400 - optimized the SynchronizedConfig class so it doesn't wait
401 unnecessarily long after an update
402 - added support for notifying instrument editors on note-on / note-off
403 events (e.g. to highlight the pressed keys on the virtual keyboard
404 of gigedit)
405 - added support for triggering notes by instrument editors (see above)
406 - be verbose on DLL load errors (on Linux)
407 - fixed di-harmonic triangle LFO implementation (this LFO implementation

409 implementation, which is usually faster)
410 - fixes for audio drivers with varying buffer sizes
411 - experimental support for running LinuxSampler as a DSSI, LV2 and
412 VST plugin
413 - notification events for stream/voice count statistics are now sent
414 only when there are actual changes
415 - added memory ordering constraints to improve stability on
416 multi-core and multi-cpu systems
417 - maximum voices and disk streams can now be altered at runtime
418 - fixed CPU feature detection on x86_64 (maybe fixes #108)
419 - automatic stacktrace mechanism is now turned off by default and can
420 be switched on by command line option "--stacktrace" (the automatic
421 stacktrace mechanism seems to be broken on most systems at the moment)
422 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
423 a pointer to the launched InstrumentEditor object
424 - added optional 3rd party user data parameter for following
425 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
426 InstrumentEditor::Launch(),
427 InstrumentManager::LaunchInstrumentEditor()
428 - theoretical fix: made SynchronizedConfig follow C++0x memory
429 model more strictly
430 - fixes for using large audio device buffers
431 - Windows: add the installation directory to the DLL search path
432 when loading an editor plugin (solves problems with VST and
433 gigedit on systems with other GTK versions installed)
434
435 * audio driver:
436 - removed the nonsense audio channel constraint (which was hard coded to
437 max. 100 audio channels) for most audio drivers
438 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
439 opposed to the LSCP specs
440 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
441 reflected the wrong value
442 - fixed a memory management bug in ASIO driver
443 - Makefile fix: JACK_CFLAGS wasn't used
444 - JACK: use jack_client_open instead of the deprecated
445 jack_client_new
446 - added (experimental) CoreAudio driver
447 - applied old fixes to the ASIO driver that were included in the
448 previous binary release but accidentally never committed to CVS
449 (fixes #117)
450 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
451 win64)
452 - VST: added support for sample rate and buffer size changes
453 - VST: close editor (Fantasia) when the VST is removed
454 - VST: avoid opening Fantasia more than once for each VST instance
455 - VST: export main function as "main" on Linux too (fix for
456 energyXT)
457 - VST: changed number of output channels from one stereo to 16
458 stereo
459 - added channel routing, fxsends and midi maps to the settings
460 stored in the plugin state
461 - performance optimization of AudioChannel::MixTo() and
462 AudioChannel::CopyTo() methods using GCC vector exensions
463 (if available)
464 - ASIO fixes: avoid initializing the device twice, avoid throwing
465 exception when getting parameters from a disconnected device
466
467 * MIDI driver:
468 - added JACK MIDI driver
469 - dispatch bank select as ordinary CC as well, the user might seriously
470 want to (mis)use it for some purpose ("fixed" in all current MIDI
471 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
472 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
473 CoreMidi or AU
474 - fixed mingw-w64 compilation error in MME driver
475 - made program change handling in MIDI thread real-time safe by
476 moving the logic to a non-RT thread
477 - fixed minor memory leak in ALSA driver
478
479 * instruments database:
480 - avoid time consuming samples scanning when adding instruments
481 to the instruments database
482 - added support for handling lost files in the instruments database
483 - Implemented option for adding instruments in separate directories
484 in the instruments database
485 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
486 - work-around for missing fnmatch function on Windows to make
487 instrument database compilable
488 - added instrument database support on Windows
489 works with both standalone mode and VST plugin.
490 the instruments DB file is located in
491 %USERPROFILE%\.linuxsampler\instruments.db which allows different
492 databases for each windows user
493 if no DB is present it automatically creates the .linuxsampler subdir
494 and then creates an empty DB
495 - fixed recursive import, which was broken on Windows
496
497 * Gigasampler format engine:
498 - fixed a memory leak that could happen when a channel was deleted
499 while notes were playing
500 - made it possible to load an instrument even if the audio thread
501 isn't running
502 - added partial support for the "Controller Triggered" MIDI rule,
503 enough for piano gigs with pedal noise samples
504 - minor fix: only mark FX sends as being modified if really the
505 respective FX send MIDI controller was used
506 - added support for GM global device volume SysEx message
507 (can be selected at compile time to either apply globally to the
508 whole sampler [default] or only to the sampler channels that are
509 connected to the respective MIDI input port the SysEx message arrived
510 on)
511 - bugfix: notes triggered at position 0 in the audio buffer were
512 sometimes wrongly killed in the same buffer, causing no sound to
513 be played
514 - added support for chromatic / drumkit mode Roland GS Sysex message
515 which is usally used to switch a part between chromatic sounds and
516 drumkit sounds (as opposed to their common default setting of MIDI
517 part 10 being a drumkit part and all other ones chromatic parts), in
518 LS however one can switch between the first 16 MIDI instrument maps
519 defined for the sampler
520 - made it possible to create multiple sample channels even if the
521 audio thread isn't running
522 - fixed crash when removing channel with active voices (#116)
523 - bugfix: on sample reference changes (instrument editor), only
524 un-cache the respective sample if it's really not used by any
525 sampler engine anymore
526 - re-cache samples in case they were changed by an instrument editor,
527 e.g. when a sample was added while playing (#82)
528 - fixed hanging notes which occured when note-off event had the exact
529 same time stamp as the voice's note-on event and occured both in the
530 same audio fragment cycle (fixes bug #112)
531 - added support for the "fine tune" and "pitch bend range"
532 instrument-level gig parameters
533 - fixed minor artifacts in pitch bend handling
534 - added support for GS Reset SysEx message
535 - allow gig files to use unlimited downward pitch shifting
536 - added a limit check for upward pitch shifting
537 - bugfix: sometimes, when playing a note twice fast, the second
538 note was silent
539 - fixed crash happening when a pitch bend event arrived at the
540 same time a new instrument was loading
541
542 * LSCP server:
543 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
544 react on MIDI data arriving on certain sampler channels (so far only
545 Note-On and Note-Off events are sent via this LSCP event)
546 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
547 react on MIDI data arriving on certain MIDI input devices (so far only
548 Note-On and Note-Off events are sent via this LSCP event)
549 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
550 SET DB_INSTRUMENT FILE_PATH
551 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
552 frontends to send MIDI messages to specific sampler channel
553 - added two additional fields to GET FILE INSTRUMENT INFO command -
554 KEY_BINDINGS and KEYSWITCH_BINDINGS
555 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
556 was incorrect
557 - Optimized the retrieval of the MIDI instrument mappings
558 - added new LSCP command "SET VOICES" to globally alter the maximum
559 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
560 be triggered respectively
561 - added new LSCP command "SET STREAMS" to globally alter the maximum
562 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
563 which will be triggered respectively
564 - bugfix: retry if "select" returns EINTR (this fixes a crash when
565 a gigedit file dialog is opened)
566 - close all connections when LSCPServer is deleted
567 - hard close of all sockets on exit
568 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
569 driver
570
571 * Bug fixes:
572 - fixed a crash which occurs when removing a sampler channel waiting
573 to start instrument loading after another channel
574 - fixed a crash which occurs when removing a sampler channel with
575 instrument loading in progress (bug #113)
576 - fixed termination caused by uncaught exception when adding MIDI
577 instrument with PERSISTENT load mode
578 - fixed possible iterator invalidations when resetting the sampler
579 - fixed memory leaks when issuing the following LSCP commands:
580 GET AUDIO_OUTPUT_DRIVER INFO
581 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
582 GET MIDI_INPUT_DRIVER INFO
583 GET MIDI_INPUT_DRIVER_PARAMETER INFO
584 - fixed possible compilation error when sqlite is not present
585 - fixed orphaned pointers when setting maximum voices limit (bug #118)
586 - fixed crash when changing the audio output device of a sampler
587 channel with loaded instrument and start playing notes
588 - fixed endless loop in Engine::SuspendAll() (bug #120)
589 - fixed a low-level atomic load function that was broken on 64-bit
590 PowerPC, which probably could cause crashes on that platform
591 - fixed a memory management error which could cause a crash when a
592 plugin was unloaded
593 - bugfix: two private structs had the same name, which could cause
594 problems if the linker chose the wrong constructor
595 - fixed low-level ConditionServer usage bug that caused lockups on
596 Windows
597
598
599 Version 0.5.1 (6 December 2007)
600
601 * packaging changes:
602 - added autoconf checks for pthread library
603 - added autoconf check for pthread bug found on certain NPTL-enabled
604 glibc versions (see Gentoo bug report #194076)
605 - added autoconf checks for MS Windows
606
607 * general changes:
608 - bugfix: the thread used by an editor plugin didn't die when the
609 editor closed
610 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
611 out all the space. operator--() did not apply size_mask after
612 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
613 order to avoid problems with the _NonVolatileReader functions.
614 - bugfix: Stream.h: added a missing divide by BytesPerSample in
615 GetWriteSpace(). Since this function is currently only used in
616 the stream's qsort() compare function, it didn't trigger any
617 bugs.
618 - Resampler.h, Synthesizer.h: cubic interpolation now works in
619 24bit mode too. Faster method to read 24bit words on little
620 endian machines (x86): replaced 3 byte reads + shifts with a 1
621 unaligned 32bit read and shift
622 - experimental support for MS Windows (MIDI input via MME, AUDIO
623 output via ASIO)
624 - made handling of SIGINT signal (Ctrl-C) a bit more robust
625 - support for monitoring the total number of active disk streams
626 (new LSCP commands: GET TOTAL_STREAM_COUNT,
627 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
628
629 * AUDIO driver:
630 - added Windows ASIO low latency audio driver
631
632 * MIDI driver:
633 - added MME Windows MIDI driver
634
635 * LSCP server:
636 - added support for Windows style path / filenames, however with
637 forward slash path separators instead of backslash
638 (i.e. "C:/foo/bar.gig")
639 - allow naughty liblscp to send non-string device parameters within
640 apostrophes as well
641 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
642 "LIST FILE INSTRUMENTS <file>" and
643 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
644 about an arbitrary instrument file on the system where the sampler is
645 running on
646
647 Version 0.5.0 (15 October 2007)
648
649 * packaging changes:
650 - config.h is not going to be installed along with liblinuxsampler's
651 API header files anymore
652 - only the API relevant header (and source) files will be exported to
653 the Doxygen API documentation (explicitly listed in Doxyfile.in)
654 - added completely new XCode project files for Mac OSX which is now
655 capable to execute our autoconf environment, thus no need anymore
656 to maintain the compile time configuration file (osx/version.h) for
657 OSX manually (patch by Toshi Nagata)
658 - fixed buggy boolean --enable-foo / --disable-foo configure script
659 parameters
660 - global.h now only covers global definitions that are needed for the
661 C++ API header files, all implementation internal global definitions
662 are now in global_private.h
663 - atomic.h is not exposed to the C++ API anymore
664 - no need to include config.h anymore for using LS's API header files
665 - fixed warnings in API doc generation
666
667 * general changes:
668 - replaced the old, confusing MIDI program change mechanism by a
669 flexible MIDI instrument mapper which allows to map arbitrary
670 (MIDI bank, MIDI program) pairs with arbitrary
671 (engine type, instrument file, file index) triplets which will be
672 loaded on the respective channel when such MIDI program change
673 messages arrive, beside that, each entry allows to define a life-time
674 strategy for the instrument, so the user can define whether the
675 instrument should i.e. be permanently loaded (to be able to switch
676 quickly among sounds) or i.e. loaded just on demand when the
677 respective program change arrives (to safe RAM space), as well as a
678 global volume factor for each entry, so the user can adjust the volume
679 dynamic of his mapped instrument collection without having to modify
680 the instrument files, also one can manage arbitrary amount of such
681 MIDI instrument maps and assign each sampler channel individually
682 a certain map, so that i.e. separation of normal instruments and
683 drumkits is possible
684 - new notification events for tracking changes to audio/MIDI devices,
685 MIDI instrument maps, MIDI instruments, FX sends, global volume.
686 - sampler was limited to load max. 200 instruments in the background
687 due to a constant size RingBuffer FIFO which is now replaced by a
688 dynamic (unlimited) size std::list FIFO
689 - added FX sends, these allow to route audio signals to arbitrary audio
690 output channels for being processed by external effect processors
691 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
692 controllers
693 - global (sampler wide) volume can now be controlled at runtime
694 - Implemented new, improved notification system
695 - fixed compilation errors regarding OSX
696 (patch by Toshi Nagata)
697 - implemented instruments database
698 - added support for escape sequences to the instruments database
699 - added highly experimental support for on-the-fly instrument editing
700 within the sampler's process (by using instrument editor plugins),
701 you'll notice the new "Registered instrument editors:" message on
702 startup, added a new LSCP command:
703 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
704 to spawn a matching instrument editor for the instrument on the
705 given sampler channel, the plugin path can be overridden at compile
706 time with ./configure --enable-plugin-dir=/some/dir
707 - added experimental code for synchronizing instrument editors hosted
708 in the sampler's process to safely edit instruments while playing
709 without a crash (hopefully) by either suspending single regions
710 wherever possible or if unavoidable whole engine(s)
711 - fixed several issues in fundamental "Thread" class: set scheduling
712 policy and priority on thread level, set a minimum stack size for
713 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
714 threads simply inherited properties of starting thread instead of
715 setting their own policy and priority
716 - minor fix in our automatic stack trace mechanism on crashes, the
717 main process did not wait for the stack trace process to finish
718 its output
719 - fixed some minor memory leaks
720 - reenabled assembly features support, at the moment only for
721 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
722 - minor assembly fix in x86 features detection (don't use the PIC
723 register, to avoid relocations in the text segment at runtime)
724 - POSIX callback functions of Thread.h are hidden
725
726 * MIDI driver:
727 - dispatch bank select (MSB and LSB) messages
728
729 * audio driver:
730 - the ALSA audio output driver parameters now reflect the correct
731 parameter value ranges for the respective selected sound card
732 (patch by Till Wimmer, a bit fixed and extended)
733
734 * Gigasampler format engine:
735 - if a filter is used and EG2 finishes before EG1, let the voice
736 die when EG2 has finished (this fixes a problem with clicks and
737 voice starvation for some gigs)
738 - playback is no longer disabled during instrument loading
739 - all notes playing on a channel that changes its instrument keep
740 playing with the old instrument until they get a note off
741 command
742 - EG fix: a release value of zero could cause noises or crash
743 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
744 - EG fine tuning: when attack is zero the EG starts at a level
745 above max sustain level, which means that there is a decay phase
746 even if sustain is 100%
747 - more EG fixes: the level could sometimes go below zero and cause
748 noises or crashes
749 - minor fix of EGDecay (patch by Toshi Nagata)
750 - fixed compiler error when --enable-override-filter-type was
751 supplied to the configure script (fixes #46)
752 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
753 instead of a fix value
754 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
755 127 (solo mode) only kill voices if the respective mode really
756 changed
757
758 * LSCP server:
759 - fixed compile time error for old Bison versions
760 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
761 - parser now supports extended ASCII character set
762 (up to ASCII code 255, i.e. includes now umlauts and accents)
763 - filename arguments in LSCP commands now allow to use escape
764 sequences, that is directly literal as one of: \', \", \\, \n, \r,
765 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
766 code value like \xf2) (fixes bug #24)
767 - the following LSCP commands now also support escape sequences for at
768 least one of their text-based parameters (i.e. name, description):
769 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
770 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
771 "SET DB_INSTRUMENT_DIRECTORY NAME",
772 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
773 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
774 "FIND DB_INSTRUMENT_DIRECTORIES"
775 - returns verbose syntax errors (line and column where syntax error
776 occured, the unexpected character and the actually expected, possible
777 character(s), the latter only if less than 5 possibilities)
778 - made sure that LSCP syntax is not affected by gigedit locale
779 settings
780 - bugfix regarding strings parameter lists: all comma separated lists
781 of strings were treated as being one string containing commas
782 (fixes #57)
783
784 * Bug fixes:
785 - fixed crash occurring on certain LSCP scripts (Bug 39)
786 - another thread safety fix for lscp "load engine" and "set
787 channel audio output device"
788 - fixed a crash which occurs when reassigning the same engine
789 on a sampler channel with connected MIDI device
790 - fixed a crash which occurs when changing the number of ports of a MIDI
791 device connected to a sampler channel to number less then or equal
792 to the index of the port to which the sampler channel is connected.
793 - The previous bindings were not been disconnected when altering
794 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
795 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
796 - The active stream/voice count statistic was incorrect.
797 - notification events were not been sent for some sampler
798 channel changes
799 - added default min and max values to restrict the number of allowed
800 audio output channels and MIDI input ports
801 - the connection to the PCM interface is now closed when destroying
802 an audio output device
803 - files with slash in their path or filename could not be loaded
804
805 * test cases:
806 - updated and fixed (haven't been touched in a while)
807
808 Version 0.4.0 (24 November 2006)
809
810 * packaging changes:
811 - changed deprecated copyright attribute to license; added ldconfig
812 to post-(un)install steps; added devel package for liblinuxsampler;
813 to linuxsampler.spec (RPM)
814 - install necessary development header files for allowing 3rd party
815 applications to link against liblinuxsampler
816 - liblinuxsampler's API documentation can be generated with 'make docs'
817 (Doxygen required)
818 - added benchmark to automatically detect the best triangle LFO
819 implementation (currently either an integer math solution or a
820 di-harmonic approximation), automatic detection can be overriden
821 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
822 configure script argument though (mandatory for cross-compilation)
823 - do not automatically pick optimized gcc flags if the user already
824 provided some on his own (as CXXFLAGS)
825 - added compile time option to disable processing of All-Notes-Off MIDI
826 messages
827 - added compile time options to allow disabling the various audio and
828 MIDI drivers
829 - fixed automatic GCC CPU switch detection on PPC
830 (patch by Ebrahim Mayat)
831
832 * Gigasampler format engine:
833 - extensive synthesis optimization
834 (reimplementation of EGs and LFO(s), removed synthesis parameter
835 prerendering and the synthesis parameter matrix in general, splitting
836 each audio fragment into subfragments now where each subfragment uses
837 constant pitch and filter coefficients. The volume coefficient is
838 linearly interpolated inside a subfragment, unless
839 --disable-interpolate-volume is set.)
840 - fine tuning of the EG modulation parameters
841 - improved filter cutoff calculation by adding support for the
842 following gig parameters: Cutoff freq (used when no cutoff
843 controller is defined), Control invert, Minimum cutoff, Velocity
844 curve and Velocity range. The keyboard tracking now scales
845 cutoff frequency instead of resonance.
846 - added support for gig parameter Resonance.
847 - fixed bug in sysex handling (patch by Juan Linietsky)
848 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
849 which can be overridden with --enable-global-attenuation
850 - EG fixes: made the length of "attack hold" stage more
851 accurate. Release stage can now start before attack stage
852 ends. Cancel release didn't work when sustain was zero. Attack
853 time now has a minimal value to prevent clicks.
854 - fixed pitch changes larger than one octave
855 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
856 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
857 all modes can be altered via standard GM messages, that is CC5 for
858 altering portamento time, CC65 for enabling / disabling portamento
859 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
860 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
861 parameter) and crossfade
862 - added support for the "attenuation controller threshold" gig
863 parameter
864 - added smoothing of volume changes caused by control change
865 messages
866 - sample loop parameters are now taken from the DimensionRegion
867 instead of the wave chunk
868 - fixed keyswitching for v3 gigs with a number of keyswitch splits
869 not equal to a power of two
870 - reimplementation of the filter algorithm. The new filter is more
871 accurate and supports all gig filter types, including bandreject
872 and lowpass turbo.
873 - real support for 24 bit samples - samples are not truncated to
874 16 bits anymore
875 - support for aftertouch (channel pressure, not polyphonic
876 aftertouch)
877 - LFO1 behaviour fixed (dampening from max volume instead of
878 amplifying from 0)
879
880 * LSCP server:
881 - fixed application exit on broken pipe error (fixes bug #20)
882 - fixed the notification messages delay due to lack of
883 network activity (fixes bug #26)
884 - fixed parser bug which occured on space(s) within device parameters
885 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
886
887 * audio driver:
888 - added aRts audio output driver (by no means RT safe)
889
890 * MIDI driver:
891 - fixed legacy sysex code which caused dispatching of MIDI SysEx
892 messages several times instead of once
893 - API extension for MIDI drivers which already supply exact time stamps
894 for events (i.e. for offline rendering based MIDI drivers)
895 - added checks for bad MIDI data
896
897 * linuxsampler application:
898 - show available sampler engine types on startup
899
900 * general changes:
901 - support for muting sampler channels and solo mode of the same, two new
902 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
903 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
904 introduced for this, the behavior is the same like on a mixer console
905 (patch by Grigor Iliev, a bit adjusted). Also added configure option
906 --enable-process-muted-channels which can be used to enable the
907 processing of muted channels.
908 - support for sostenuto pedal
909 - support for monitoring the total number of active voices
910 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
911 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
912 - fixed some memory management errors
913 - fixed some concurrency problems that could lead to crashes when
914 LSCP commands were executed
915 - fixed crash when instrument loading failed previously on the same
916 sampler channel (fixes bug #36)
917
918 Version 0.3.3 (15 July 2005)
919
920 * packaging changes:
921 - fixed compilation with gcc 4.0
922
923 * Gigasampler format engine:
924 - LFO preprocessing was performed even though the respective LFO was
925 disabled by the instrument patch (minor efficiency fix)
926 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
927 for volume ramp downs in the same fragment (needed for current voice
928 stealing implementation) then simply inform the user with a warning
929 about possible click sounds and reduce the volume ramp down
930 appropriately instead of cancelling the audio device connection
931
932 Version 0.3.2 (24 June 2005)
933
934 * packaging changes:
935 - updated autotools build files to compile on OS X
936 (conditional compilation of CoreMIDI and MidiShare drivers)
937 - hand-crafted assembly optimization code can be disabled with
938 './configure --disable-asm' (definitely not recommended)
939 - fixed 'make dist' rule to include all necessary files
940 - require automake (>= 1.5) for 'make -f Makefile.cvs'
941 (due to 'dist-bzip2' automake option)
942
943 * Gigasampler format engine:
944 - support for the gig parameters for "release velocity response" curves
945 - fine tuning of the EGADSR envelope
946 - volume of release triggered samples now depends on note-on velocity,
947 note length and gig parameter "release trigger decay" instead of
948 note-off velocity.
949 - revised voice stealing
950 (fixes crash and endless loop caused by voice stealing)
951 - don't reset scale tuning on instrument or audio output device change
952 - handle key group conflicts right at the beginning of each fragment
953 instead of when the respective voice is actually launched
954 (fixes undefined behavior if stolen voices belonged to a key group -
955 this case was followed by a "killed voice survived" error message)
956 - fixed minor issue with null/silence samples
957 (those stole voices even though they don't need a voice at all which
958 resulted in "voice stealing didn't work out" messages)
959 - don't reset volume, pan, pitch and MIDI controller values on
960 instrument or audio output device change
961
962 * LSCP server:
963 - fixed some crashes (patch by Grigor Iliev, fixes #19)
964 - fixed LSCP event "CHANNEL_INFO" notification
965 (e.g. did not notify on volume changes or MIDI program change events)
966
967 * linuxsampler application:
968 - added command line parameters --lscp-addr and --lscp-port to override
969 default IP address and port of LSCP server
970
971 Version 0.3.1 (24 May 2005)
972
973 * initial release
