291     took the full preloading time and on 1st program change the respective
292     instrument was completely reloaded again.

294     sent to the same sampler channel (patch from the Open Octave
295     project, slightly adjusted)

313 persson 1897 - Windows: look for editor plugins and Fantasia using base
314 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
315     directory above)
316 persson 1899 - configure script fix: removed unconditional use of SSE
317 persson 1923 - fixed building with sqlite installed in a non-standard directory

319     - fix for new mingw-w64 version, which has usleep
320 schoenebeck 1639
321 schoenebeck 1601 * general changes:
322     - bugfix: on some POSIX systems instrument editor plugins refused to
323     load as we used a non-portable Linux specific struct field
324     (fixes bug #70, patch by Ronald Baljeu)
325 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
326     plugin DLL on Windows systems failed
327 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
328     - optimized the SynchronizedConfig class so it doesn't wait
329     unnecessarily long after an update
330 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
331     events (e.g. to highlight the pressed keys on the virtual keyboard
332     of gigedit)
333 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
334 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
335 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
336     is only used by very few systems, most pick the int math
337     implementation, which is usually faster)
338 persson 1748 - fixes for audio drivers with varying buffer sizes
339 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
340     VST plugin
341 iliev 1789 - notification events for stream/voice count statistics are now sent

344     multi-core and multi-cpu systems
345 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
346 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
347 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
348     be switched on by command line option "--stacktrace" (the automatic
349     stacktrace mechanism seems to be broken on most systems at the moment)
350 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
351     a pointer to the launched InstrumentEditor object
352 schoenebeck 1876 - added optional 3rd party user data parameter for following
353     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
354     InstrumentEditor::Launch(),
355     InstrumentManager::LaunchInstrumentEditor()
356 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
357     model more strictly
358 persson 1895 - fixes for using large audio device buffers
359 persson 1951 - Windows: add the installation directory to the DLL search path
360     when loading an editor plugin (solves problems with VST and
361     gigedit on systems with other GTK versions installed)
362 schoenebeck 1601
363 schoenebeck 1599 * audio driver:
364     - removed the nonsense audio channel constraint (which was hard coded to
365     max. 100 audio channels) for most audio drivers
366 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
367     opposed to the LSCP specs
368 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
369     reflected the wrong value
370 persson 1644 - fixed a memory management bug in ASIO driver
371 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
372 persson 1777 - JACK: use jack_client_open instead of the deprecated
373 persson 1748 jack_client_new
374 iliev 1829 - added (experimental) CoreAudio driver
375 persson 1888 - applied old fixes to the ASIO driver that were included in the
376     previous binary release but accidentally never committed to CVS
377     (fixes #117)
378 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
379     win64)
380 persson 1895 - VST: added support for sample rate and buffer size changes
381     - VST: close editor (Fantasia) when the VST is removed
382 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
383     - VST: export main function as "main" on Linux too (fix for
384     energyXT)
385 persson 1917 - VST: changed number of output channels from one stereo to 16
386     stereo
387 persson 1922 - added channel routing, fxsends and midi maps to the settings
388     stored in the plugin state
389 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
390     AudioChannel::CopyTo() methods using GCC vector exensions
391     (if available)
392 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
393     exception when getting parameters from a disconnected device
394 schoenebeck 1599
395 persson 1651 * MIDI driver:
396     - added JACK MIDI driver
397 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
398     want to (mis)use it for some purpose ("fixed" in all current MIDI
399     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
400 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
401 persson 1887 CoreMidi or AU
402 persson 1889 - fixed mingw-w64 compilation error in MME driver
403 persson 1924 - made program change handling in MIDI thread real-time safe by
404     moving the logic to a non-RT thread
405 persson 1951 - fixed minor memory leak in ALSA driver
406 persson 1651
407 schoenebeck 1604 * instruments database:
408 iliev 1603 - avoid time consuming samples scanning when adding instruments
409     to the instruments database
410 iliev 1727 - added support for handling lost files in the instruments database
411 iliev 1781 - Implemented option for adding instruments in separate directories
412     in the instruments database
413     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
414 persson 1908 - work-around for missing fnmatch function on Windows to make
415     instrument database compilable
416 schoenebeck 1930 - added instrument database support on Windows
417     works with both standalone mode and VST plugin.
418     the instruments DB file is located in
419     %USERPROFILE%\.linuxsampler\instruments.db which allows different
420     databases for each windows user
421     if no DB is present it automatically creates the .linuxsampler subdir
422     and then creates an empty DB
423 persson 1943 - fixed recursive import, which was broken on Windows
424 iliev 1603
425 persson 1644 * Gigasampler format engine:
426     - fixed a memory leak that could happen when a channel was deleted
427     while notes were playing
428 persson 1646 - made it possible to load an instrument even if the audio thread
429     isn't running
430 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
431     enough for piano gigs with pedal noise samples
432 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
433     respective FX send MIDI controller was used
434 schoenebeck 1724 - added support for GM global device volume SysEx message
435 schoenebeck 1762 (can be selected at compile time to either apply globally to the
436     whole sampler [default] or only to the sampler channels that are
437     connected to the respective MIDI input port the SysEx message arrived
438     on)
439 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
440     sometimes wrongly killed in the same buffer, causing no sound to
441     be played
442 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
443     which is usally used to switch a part between chromatic sounds and
444     drumkit sounds (as opposed to their common default setting of MIDI
445     part 10 being a drumkit part and all other ones chromatic parts), in
446     LS however one can switch between the first 16 MIDI instrument maps
447     defined for the sampler
448 persson 1764 - made it possible to create multiple sample channels even if the
449     audio thread isn't running
450 persson 1844 - fixed crash when removing channel with active voices (#116)
451 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
452     un-cache the respective sample if it's really not used by any
453     sampler engine anymore
454     - re-cache samples in case they were changed by an instrument editor,
455     e.g. when a sample was added while playing (#82)
456 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
457     same time stamp as the voice's note-on event and occured both in the
458     same audio fragment cycle (fixes bug #112)
459 persson 1858 - added support for the "fine tune" and "pitch bend range"
460     instrument-level gig parameters
461     - fixed minor artifacts in pitch bend handling
462 schoenebeck 1860 - added support for GS Reset SysEx message
463 persson 1862 - allow gig files to use unlimited downward pitch shifting
464     - added a limit check for upward pitch shifting
465 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
466     note was silent
467 persson 1923 - fixed crash happening when a pitch bend event arrived at the
468     same time a new instrument was loading
469 persson 1644
470 schoenebeck 1687 * LSCP server:
471     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
472     react on MIDI data arriving on certain sampler channels (so far only
473     Note-On and Note-Off events are sent via this LSCP event)
474 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
475     react on MIDI data arriving on certain MIDI input devices (so far only
476     Note-On and Note-Off events are sent via this LSCP event)
477 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
478     SET DB_INSTRUMENT FILE_PATH
479 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
480     frontends to send MIDI messages to specific sampler channel
481     - added two additional fields to GET FILE INSTRUMENT INFO command -
482     KEY_BINDINGS and KEYSWITCH_BINDINGS
483 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
484     was incorrect
485 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
486 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
487     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
488     be triggered respectively
489     - added new LSCP command "SET STREAMS" to globally alter the maximum
490     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
491     which will be triggered respectively
492 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
493     a gigedit file dialog is opened)
494 iliev 1848 - close all connections when LSCPServer is deleted
495 iliev 1882 - hard close of all sockets on exit
496 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
497     driver
498 schoenebeck 1687
499 iliev 1761 * Bug fixes:
500     - fixed a crash which occurs when removing a sampler channel waiting
501     to start instrument loading after another channel
502 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
503     instrument loading in progress (bug #113)
504 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
505     instrument with PERSISTENT load mode
506 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
507     - fixed memory leaks when issuing the following LSCP commands:
508     GET AUDIO_OUTPUT_DRIVER INFO
509     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
510     GET MIDI_INPUT_DRIVER INFO
511     GET MIDI_INPUT_DRIVER_PARAMETER INFO
512     - fixed possible compilation error when sqlite is not present
513 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
514 iliev 1847 - fixed crash when changing the audio output device of a sampler
515     channel with loaded instrument and start playing notes
516 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
517 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
518     PowerPC, which probably could cause crashes on that platform
519 persson 1889 - fixed a memory management error which could cause a crash when a
520     plugin was unloaded
521 persson 1896 - bugfix: two private structs had the same name, which could cause
522     problems if the linker chose the wrong constructor
523 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
524     Windows
525 iliev 1761
526    
527 schoenebeck 1560 Version 0.5.1 (6 December 2007)
528 schoenebeck 1454
529     * packaging changes:
530     - added autoconf checks for pthread library
531     - added autoconf check for pthread bug found on certain NPTL-enabled
532     glibc versions (see Gentoo bug report #194076)
533 senoner 1502 - added autoconf checks for MS Windows
534 schoenebeck 1454
535 persson 1455 * general changes:
536     - bugfix: the thread used by an editor plugin didn't die when the
537     editor closed
538 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
539     out all the space. operator--() did not apply size_mask after
540     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
541     order to avoid problems with the _NonVolatileReader functions.
542     - bugfix: Stream.h: added a missing divide by BytesPerSample in
543     GetWriteSpace(). Since this function is currently only used in
544     the stream's qsort() compare function, it didn't trigger any
545     bugs.
546     - Resampler.h, Synthesizer.h: cubic interpolation now works in
547     24bit mode too. Faster method to read 24bit words on little
548     endian machines (x86): replaced 3 byte reads + shifts with a 1
549     unaligned 32bit read and shift
550     - experimental support for MS Windows (MIDI input via MME, AUDIO
551     output via ASIO)
552     - made handling of SIGINT signal (Ctrl-C) a bit more robust
553 iliev 1541 - support for monitoring the total number of active disk streams
554     (new LSCP commands: GET TOTAL_STREAM_COUNT,
555     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
556 persson 1455
557 senoner 1500 * AUDIO driver:
558 persson 1534 - added Windows ASIO low latency audio driver
559 senoner 1500
560 senoner 1485 * MIDI driver:
561 schoenebeck 1495 - added MME Windows MIDI driver
562 senoner 1485
563 schoenebeck 1471 * LSCP server:
564     - added support for Windows style path / filenames, however with
565     forward slash path separators instead of backslash
566     (i.e. "C:/foo/bar.gig")
567 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
568     apostrophes as well
569 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
570     "LIST FILE INSTRUMENTS <file>" and
571     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
572     about an arbitrary instrument file on the system where the sampler is
573     running on
574 schoenebeck 1471
575 schoenebeck 1424 Version 0.5.0 (15 October 2007)
576 schoenebeck 947
577 schoenebeck 1065 * packaging changes:
578 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
579     API header files anymore
580 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
581     the Doxygen API documentation (explicitly listed in Doxyfile.in)
582 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
583     capable to execute our autoconf environment, thus no need anymore
584     to maintain the compile time configuration file (osx/version.h) for
585     OSX manually (patch by Toshi Nagata)
586 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
587     parameters
588 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
589     C++ API header files, all implementation internal global definitions
590     are now in global_private.h
591     - atomic.h is not exposed to the C++ API anymore
592     - no need to include config.h anymore for using LS's API header files
593     - fixed warnings in API doc generation
594 schoenebeck 1065
595 schoenebeck 947 * general changes:
596     - replaced the old, confusing MIDI program change mechanism by a
597     flexible MIDI instrument mapper which allows to map arbitrary
598 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
599 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
600     loaded on the respective channel when such MIDI program change
601     messages arrive, beside that, each entry allows to define a life-time
602     strategy for the instrument, so the user can define whether the
603     instrument should i.e. be permanently loaded (to be able to switch
604     quickly among sounds) or i.e. loaded just on demand when the
605     respective program change arrives (to safe RAM space), as well as a
606     global volume factor for each entry, so the user can adjust the volume
607     dynamic of his mapped instrument collection without having to modify
608 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
609     MIDI instrument maps and assign each sampler channel individually
610     a certain map, so that i.e. separation of normal instruments and
611     drumkits is possible
612 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
613     MIDI instrument maps, MIDI instruments, FX sends, global volume.
614 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
615     due to a constant size RingBuffer FIFO which is now replaced by a
616     dynamic (unlimited) size std::list FIFO
617 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
618     output channels for being processed by external effect processors
619     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
620     controllers
621 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
622 iliev 1130 - Implemented new, improved notification system
623 schoenebeck 1149 - fixed compilation errors regarding OSX
624     (patch by Toshi Nagata)
625 iliev 1161 - implemented instruments database
626 iliev 1345 - added support for escape sequences to the instruments database
627 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
628     within the sampler's process (by using instrument editor plugins),
629     you'll notice the new "Registered instrument editors:" message on
630 schoenebeck 1407 startup, added a new LSCP command:
631     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
632 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
633     given sampler channel, the plugin path can be overridden at compile
634     time with ./configure --enable-plugin-dir=/some/dir
635 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
636     in the sampler's process to safely edit instruments while playing
637     without a crash (hopefully) by either suspending single regions
638     wherever possible or if unavoidable whole engine(s)
639 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
640     policy and priority on thread level, set a minimum stack size for
641     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
642     threads simply inherited properties of starting thread instead of
643     setting their own policy and priority
644 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
645     main process did not wait for the stack trace process to finish
646     its output
647 persson 1248 - fixed some minor memory leaks
648 schoenebeck 1259 - reenabled assembly features support, at the moment only for
649     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
650 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
651     register, to avoid relocations in the text segment at runtime)
652 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
653 schoenebeck 947
654     * MIDI driver:
655     - dispatch bank select (MSB and LSB) messages
656    
657 schoenebeck 1049 * audio driver:
658     - the ALSA audio output driver parameters now reflect the correct
659     parameter value ranges for the respective selected sound card
660     (patch by Till Wimmer, a bit fixed and extended)
661    
662 persson 951 * Gigasampler format engine:
663     - if a filter is used and EG2 finishes before EG1, let the voice
664     die when EG2 has finished (this fixes a problem with clicks and
665     voice starvation for some gigs)
666 persson 1038 - playback is no longer disabled during instrument loading
667     - all notes playing on a channel that changes its instrument keep
668     playing with the old instrument until they get a note off
669     command
670 persson 1039 - EG fix: a release value of zero could cause noises or crash
671 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
672 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
673     above max sustain level, which means that there is a decay phase
674     even if sustain is 100%
675 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
676     noises or crashes
677 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
678 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
679     supplied to the configure script (fixes #46)
680 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
681     instead of a fix value
682 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
683     127 (solo mode) only kill voices if the respective mode really
684     changed
685 persson 951
686 schoenebeck 1244 * LSCP server:
687     - fixed compile time error for old Bison versions
688     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
689 schoenebeck 1245 - parser now supports extended ASCII character set
690     (up to ASCII code 255, i.e. includes now umlauts and accents)
691     - filename arguments in LSCP commands now allow to use escape
692     sequences, that is directly literal as one of: \', \", \\, \n, \r,
693     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
694     code value like \xf2) (fixes bug #24)
695 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
696     least one of their text-based parameters (i.e. name, description):
697     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
698     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
699     "SET DB_INSTRUMENT_DIRECTORY NAME",
700     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
701     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
702     "FIND DB_INSTRUMENT_DIRECTORIES"
703 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
704     occured, the unexpected character and the actually expected, possible
705     character(s), the latter only if less than 5 possibilities)
706 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
707     settings
708 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
709     of strings were treated as being one string containing commas
710     (fixes #57)
711 schoenebeck 1244
712 iliev 959 * Bug fixes:
713     - fixed crash occurring on certain LSCP scripts (Bug 39)
714 persson 1038 - another thread safety fix for lscp "load engine" and "set
715     channel audio output device"
716 iliev 1283 - fixed a crash which occurs when reassigning the same engine
717     on a sampler channel with connected MIDI device
718 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
719     device connected to a sampler channel to number less then or equal
720     to the index of the port to which the sampler channel is connected.
721 iliev 1296 - The previous bindings were not been disconnected when altering
722     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
723     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
724 iliev 1297 - The active stream/voice count statistic was incorrect.
725 iliev 1298 - notification events were not been sent for some sampler
726     channel changes
727 iliev 1305 - added default min and max values to restrict the number of allowed
728     audio output channels and MIDI input ports
729 iliev 1306 - the connection to the PCM interface is now closed when destroying
730     an audio output device
731 schoenebeck 1332 - files with slash in their path or filename could not be loaded
732 iliev 959
733 schoenebeck 1221 * test cases:
734     - updated and fixed (haven't been touched in a while)
735    
736 schoenebeck 937 Version 0.4.0 (24 November 2006)
737 persson 696
738 schoenebeck 697 * packaging changes:
739 capela 868 - changed deprecated copyright attribute to license; added ldconfig
740     to post-(un)install steps; added devel package for liblinuxsampler;
741     to linuxsampler.spec (RPM)
742 schoenebeck 697 - install necessary development header files for allowing 3rd party
743     applications to link against liblinuxsampler
744     - liblinuxsampler's API documentation can be generated with 'make docs'
745     (Doxygen required)
746 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
747     implementation (currently either an integer math solution or a
748     di-harmonic approximation), automatic detection can be overriden
749     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
750     configure script argument though (mandatory for cross-compilation)
751 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
752     provided some on his own (as CXXFLAGS)
753 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
754     messages
755 schoenebeck 852 - added compile time options to allow disabling the various audio and
756     MIDI drivers
757 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
758     (patch by Ebrahim Mayat)
759 schoenebeck 697
760 persson 696 * Gigasampler format engine:
761 schoenebeck 738 - extensive synthesis optimization
762     (reimplementation of EGs and LFO(s), removed synthesis parameter
763     prerendering and the synthesis parameter matrix in general, splitting
764     each audio fragment into subfragments now where each subfragment uses
765 persson 830 constant pitch and filter coefficients. The volume coefficient is
766     linearly interpolated inside a subfragment, unless
767     --disable-interpolate-volume is set.)
768 persson 696 - fine tuning of the EG modulation parameters
769 persson 729 - improved filter cutoff calculation by adding support for the
770     following gig parameters: Cutoff freq (used when no cutoff
771     controller is defined), Control invert, Minimum cutoff, Velocity
772 persson 791 curve and Velocity range. The keyboard tracking now scales
773     cutoff frequency instead of resonance.
774 persson 877 - added support for gig parameter Resonance.
775 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
776 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
777     which can be overridden with --enable-global-attenuation
778 persson 783 - EG fixes: made the length of "attack hold" stage more
779     accurate. Release stage can now start before attack stage
780 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
781     time now has a minimal value to prevent clicks.
782 persson 799 - fixed pitch changes larger than one octave
783 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
784     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
785     all modes can be altered via standard GM messages, that is CC5 for
786     altering portamento time, CC65 for enabling / disabling portamento
787     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
788 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
789     parameter) and crossfade
790 persson 831 - added support for the "attenuation controller threshold" gig
791     parameter
792 persson 832 - added smoothing of volume changes caused by control change
793     messages
794 persson 865 - sample loop parameters are now taken from the DimensionRegion
795     instead of the wave chunk
796     - fixed keyswitching for v3 gigs with a number of keyswitch splits
797     not equal to a power of two
798 persson 877 - reimplementation of the filter algorithm. The new filter is more
799     accurate and supports all gig filter types, including bandreject
800     and lowpass turbo.
801 persson 903 - real support for 24 bit samples - samples are not truncated to
802     16 bits anymore
803     - support for aftertouch (channel pressure, not polyphonic
804     aftertouch)
805 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
806     amplifying from 0)
807 persson 696
808 schoenebeck 711 * LSCP server:
809     - fixed application exit on broken pipe error (fixes bug #20)
810 iliev 793 - fixed the notification messages delay due to lack of
811     network activity (fixes bug #26)
812 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
813     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
814 schoenebeck 711
815 schoenebeck 838 * audio driver:
816     - added aRts audio output driver (by no means RT safe)
817    
818 schoenebeck 775 * MIDI driver:
819     - fixed legacy sysex code which caused dispatching of MIDI SysEx
820     messages several times instead of once
821 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
822     for events (i.e. for offline rendering based MIDI drivers)
823 persson 922 - added checks for bad MIDI data
824 schoenebeck 775
825 schoenebeck 900 * linuxsampler application:
826     - show available sampler engine types on startup
827    
828 schoenebeck 705 * general changes:
829     - support for muting sampler channels and solo mode of the same, two new
830     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
831     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
832     introduced for this, the behavior is the same like on a mixer console
833 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
834     --enable-process-muted-channels which can be used to enable the
835     processing of muted channels.
836 iliev 777 - support for sostenuto pedal
837 iliev 779 - support for monitoring the total number of active voices
838 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
839     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
840 persson 835 - fixed some memory management errors
841 persson 841 - fixed some concurrency problems that could lead to crashes when
842     LSCP commands were executed
843 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
844     sampler channel (fixes bug #36)
845 schoenebeck 705
846 schoenebeck 692 Version 0.3.3 (15 July 2005)
847 schoenebeck 686
848     * packaging changes:
849     - fixed compilation with gcc 4.0
850    
851 schoenebeck 687 * Gigasampler format engine:
852     - LFO preprocessing was performed even though the respective LFO was
853     disabled by the instrument patch (minor efficiency fix)
854 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
855     for volume ramp downs in the same fragment (needed for current voice
856     stealing implementation) then simply inform the user with a warning
857     about possible click sounds and reduce the volume ramp down
858     appropriately instead of cancelling the audio device connection
859 schoenebeck 687
860 schoenebeck 677 Version 0.3.2 (24 June 2005)
861 schoenebeck 609
862     * packaging changes:
863     - updated autotools build files to compile on OS X
864     (conditional compilation of CoreMIDI and MidiShare drivers)
865 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
866     './configure --disable-asm' (definitely not recommended)
867 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
868     - require automake (>= 1.5) for 'make -f Makefile.cvs'
869     (due to 'dist-bzip2' automake option)
870 schoenebeck 649
871     * Gigasampler format engine:
872     - support for the gig parameters for "release velocity response" curves
873     - fine tuning of the EGADSR envelope
874     - volume of release triggered samples now depends on note-on velocity,
875     note length and gig parameter "release trigger decay" instead of
876     note-off velocity.
877 schoenebeck 663 - revised voice stealing
878     (fixes crash and endless loop caused by voice stealing)
879 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
880 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
881     instead of when the respective voice is actually launched
882     (fixes undefined behavior if stolen voices belonged to a key group -
883     this case was followed by a "killed voice survived" error message)
884 schoenebeck 669 - fixed minor issue with null/silence samples
885     (those stole voices even though they don't need a voice at all which
886     resulted in "voice stealing didn't work out" messages)
887 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
888     instrument or audio output device change
889 schoenebeck 654
890 schoenebeck 620 * LSCP server:
891 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
892 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
893 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
894 schoenebeck 609
895 schoenebeck 668 * linuxsampler application:
896     - added command line parameters --lscp-addr and --lscp-port to override
897     default IP address and port of LSCP server
898    
899 schoenebeck 579 Version 0.3.1 (24 May 2005)
900    
901     * initial release
