2    
3 capela 2174 * plugin changes:
4     - LV2 Persist + Files support (patch by David Robillard)
5    
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8 persson 2183 - 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"

17     * general changes:
18 iliev 2012 - Refactoring: moved the independent code from
19     the Gigasampler format engine to base classes
20 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
21     respective profiling code is currently broken
22 schoenebeck 2053 - Introduced support for optional environment variable

30     the 1st effect send of the sampler channel, no matter what the actual
31     effect type is)
32     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
33     note (in this implementation of the sampler its simply hard routed to
34     the 2nd effect send of the sampler channel, no matter what the actual
35     effect type is)

176 schoenebeck 1599
177 schoenebeck 1639 * packaging changes:

196 schoenebeck 1639
197 schoenebeck 1601 * general changes:
198     - bugfix: on some POSIX systems instrument editor plugins refused to

223 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
224     be switched on by command line option "--stacktrace" (the automatic
225     stacktrace mechanism seems to be broken on most systems at the moment)
226 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
227     a pointer to the launched InstrumentEditor object
228 schoenebeck 1876 - added optional 3rd party user data parameter for following
229     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
230     InstrumentEditor::Launch(),

242 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
243     opposed to the LSCP specs
244 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)

249 persson 1748 jack_client_new
250 iliev 1829 - added (experimental) CoreAudio driver
251 persson 1888 - applied old fixes to the ASIO driver that were included in the
252     previous binary release but accidentally never committed to CVS
253     (fixes #117)
254 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
255     win64)

266     AudioChannel::CopyTo() methods using GCC vector exensions
267     (if available)
268 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
269     exception when getting parameters from a disconnected device
270 schoenebeck 1599
271 persson 1651 * MIDI driver:
272     - added JACK MIDI driver
273 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

291     instrument database compilable
292 schoenebeck 1930 - added instrument database support on Windows
293     works with both standalone mode and VST plugin.
294     the instruments DB file is located in
295     %USERPROFILE%\.linuxsampler\instruments.db which allows different
296     databases for each windows user
297     if no DB is present it automatically creates the .linuxsampler subdir
298     and then creates an empty DB
299 persson 1943 - fixed recursive import, which was broken on Windows
300 iliev 1603
301 persson 1644 * Gigasampler format engine:
302     - fixed a memory leak that could happen when a channel was deleted
303     while notes were playing
304 persson 1646 - made it possible to load an instrument even if the audio thread
305     isn't running
306 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
307     enough for piano gigs with pedal noise samples
308 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
309     respective FX send MIDI controller was used
310 schoenebeck 1724 - added support for GM global device volume SysEx message
311 schoenebeck 1762 (can be selected at compile time to either apply globally to the
312     whole sampler [default] or only to the sampler channels that are
313     connected to the respective MIDI input port the SysEx message arrived
314     on)
315 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
316     sometimes wrongly killed in the same buffer, causing no sound to
317     be played
318 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
319     which is usally used to switch a part between chromatic sounds and
320     drumkit sounds (as opposed to their common default setting of MIDI
321     part 10 being a drumkit part and all other ones chromatic parts), in
322     LS however one can switch between the first 16 MIDI instrument maps
323     defined for the sampler
324 persson 1764 - made it possible to create multiple sample channels even if the
325     audio thread isn't running
326 persson 1844 - fixed crash when removing channel with active voices (#116)

328     un-cache the respective sample if it's really not used by any
329     sampler engine anymore
330     - re-cache samples in case they were changed by an instrument editor,
331     e.g. when a sample was added while playing (#82)
332 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
333     same time stamp as the voice's note-on event and occured both in the
334     same audio fragment cycle (fixes bug #112)
335 persson 1858 - added support for the "fine tune" and "pitch bend range"
336     instrument-level gig parameters
337     - fixed minor artifacts in pitch bend handling
338 schoenebeck 1860 - added support for GS Reset SysEx message
339 persson 1862 - allow gig files to use unlimited downward pitch shifting
340     - added a limit check for upward pitch shifting
341 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
342     note was silent
343 persson 1923 - fixed crash happening when a pitch bend event arrived at the
344     same time a new instrument was loading
345 persson 1644
346 schoenebeck 1687 * LSCP server:
347     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
348     react on MIDI data arriving on certain sampler channels (so far only
349     Note-On and Note-Off events are sent via this LSCP event)
350 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
351     react on MIDI data arriving on certain MIDI input devices (so far only
352     Note-On and Note-Off events are sent via this LSCP event)
353 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
354     SET DB_INSTRUMENT FILE_PATH
355 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
356     frontends to send MIDI messages to specific sampler channel
357     - added two additional fields to GET FILE INSTRUMENT INFO command -
358     KEY_BINDINGS and KEYSWITCH_BINDINGS
359 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
360     was incorrect
361 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
362 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
363     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
364     be triggered respectively
365     - added new LSCP command "SET STREAMS" to globally alter the maximum
366     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
367     which will be triggered respectively
368 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
369     a gigedit file dialog is opened)

386     GET MIDI_INPUT_DRIVER INFO
387     GET MIDI_INPUT_DRIVER_PARAMETER INFO
388     - fixed possible compilation error when sqlite is not present
389 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
390 iliev 1847 - fixed crash when changing the audio output device of a sampler
391     channel with loaded instrument and start playing notes
392 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
393 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
394     PowerPC, which probably could cause crashes on that platform
395 persson 1889 - fixed a memory management error which could cause a crash when a
396     plugin was unloaded
397 persson 1896 - bugfix: two private structs had the same name, which could cause
398     problems if the linker chose the wrong constructor
399 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
400     Windows

403 schoenebeck 1560 Version 0.5.1 (6 December 2007)
404 schoenebeck 1454
405     * packaging changes:
406     - added autoconf checks for pthread library
407     - added autoconf check for pthread bug found on certain NPTL-enabled
408     glibc versions (see Gentoo bug report #194076)
409 senoner 1502 - added autoconf checks for MS Windows
410 schoenebeck 1454
411 persson 1455 * general changes:
412     - bugfix: the thread used by an editor plugin didn't die when the
413     editor closed
414 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
415     out all the space. operator--() did not apply size_mask after
416     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
417     order to avoid problems with the _NonVolatileReader functions.
418     - bugfix: Stream.h: added a missing divide by BytesPerSample in
419     GetWriteSpace(). Since this function is currently only used in
420     the stream's qsort() compare function, it didn't trigger any
421     bugs.
422     - Resampler.h, Synthesizer.h: cubic interpolation now works in
423     24bit mode too. Faster method to read 24bit words on little
424     endian machines (x86): replaced 3 byte reads + shifts with a 1
425     unaligned 32bit read and shift
426     - experimental support for MS Windows (MIDI input via MME, AUDIO
427     output via ASIO)
428     - made handling of SIGINT signal (Ctrl-C) a bit more robust
429 iliev 1541 - support for monitoring the total number of active disk streams
430     (new LSCP commands: GET TOTAL_STREAM_COUNT,
431     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
432 persson 1455
433 senoner 1500 * AUDIO driver:
434 persson 1534 - added Windows ASIO low latency audio driver
435 senoner 1500
436 senoner 1485 * MIDI driver:
437 schoenebeck 1495 - added MME Windows MIDI driver
438 senoner 1485
439 schoenebeck 1471 * LSCP server:
440     - added support for Windows style path / filenames, however with
441     forward slash path separators instead of backslash
442     (i.e. "C:/foo/bar.gig")
443 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
444     apostrophes as well
445 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
446     "LIST FILE INSTRUMENTS <file>" and
447     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
448     about an arbitrary instrument file on the system where the sampler is
449     running on
450 schoenebeck 1471
451 schoenebeck 1424 Version 0.5.0 (15 October 2007)
452 schoenebeck 947
453 schoenebeck 1065 * packaging changes:
454 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
455     API header files anymore
456 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
457     the Doxygen API documentation (explicitly listed in Doxyfile.in)
458 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
459     capable to execute our autoconf environment, thus no need anymore
460     to maintain the compile time configuration file (osx/version.h) for
461     OSX manually (patch by Toshi Nagata)
462 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
463     parameters
464 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
465     C++ API header files, all implementation internal global definitions
466     are now in global_private.h
467     - atomic.h is not exposed to the C++ API anymore
468     - no need to include config.h anymore for using LS's API header files
469     - fixed warnings in API doc generation
470 schoenebeck 1065
471 schoenebeck 947 * general changes:
472     - replaced the old, confusing MIDI program change mechanism by a
473     flexible MIDI instrument mapper which allows to map arbitrary
474 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
475 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
476     loaded on the respective channel when such MIDI program change
477     messages arrive, beside that, each entry allows to define a life-time
478     strategy for the instrument, so the user can define whether the
479     instrument should i.e. be permanently loaded (to be able to switch
480     quickly among sounds) or i.e. loaded just on demand when the
481     respective program change arrives (to safe RAM space), as well as a
482     global volume factor for each entry, so the user can adjust the volume
483     dynamic of his mapped instrument collection without having to modify
484 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
485     MIDI instrument maps and assign each sampler channel individually
486     a certain map, so that i.e. separation of normal instruments and
487     drumkits is possible
488 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
489     MIDI instrument maps, MIDI instruments, FX sends, global volume.
490 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
491     due to a constant size RingBuffer FIFO which is now replaced by a
492     dynamic (unlimited) size std::list FIFO
493 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
494     output channels for being processed by external effect processors
495     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
496     controllers
497 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
498 iliev 1130 - Implemented new, improved notification system
499 schoenebeck 1149 - fixed compilation errors regarding OSX
500     (patch by Toshi Nagata)
501 iliev 1161 - implemented instruments database
502 iliev 1345 - added support for escape sequences to the instruments database
503 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
504     within the sampler's process (by using instrument editor plugins),
505     you'll notice the new "Registered instrument editors:" message on
506 schoenebeck 1407 startup, added a new LSCP command:
507     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
508 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
509     given sampler channel, the plugin path can be overridden at compile
510     time with ./configure --enable-plugin-dir=/some/dir
511 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
512     in the sampler's process to safely edit instruments while playing
513     without a crash (hopefully) by either suspending single regions
514     wherever possible or if unavoidable whole engine(s)
515 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
516     policy and priority on thread level, set a minimum stack size for
517     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
518     threads simply inherited properties of starting thread instead of
519     setting their own policy and priority
520 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
521     main process did not wait for the stack trace process to finish
522     its output
523 persson 1248 - fixed some minor memory leaks
524 schoenebeck 1259 - reenabled assembly features support, at the moment only for
525     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
526 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
527     register, to avoid relocations in the text segment at runtime)
528 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
529 schoenebeck 947
530     * MIDI driver:
531     - dispatch bank select (MSB and LSB) messages
532    
533 schoenebeck 1049 * audio driver:
534     - the ALSA audio output driver parameters now reflect the correct
535     parameter value ranges for the respective selected sound card
536     (patch by Till Wimmer, a bit fixed and extended)
537    
538 persson 951 * Gigasampler format engine:
539     - if a filter is used and EG2 finishes before EG1, let the voice
540     die when EG2 has finished (this fixes a problem with clicks and
541     voice starvation for some gigs)
542 persson 1038 - playback is no longer disabled during instrument loading
543     - all notes playing on a channel that changes its instrument keep
544     playing with the old instrument until they get a note off
545     command
546 persson 1039 - EG fix: a release value of zero could cause noises or crash
547 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
548 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
549     above max sustain level, which means that there is a decay phase
550     even if sustain is 100%
551 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
552     noises or crashes
553 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
554 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
555     supplied to the configure script (fixes #46)
556 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
557     instead of a fix value
558 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
559     127 (solo mode) only kill voices if the respective mode really
560     changed
561 persson 951
562 schoenebeck 1244 * LSCP server:
563     - fixed compile time error for old Bison versions
564     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
565 schoenebeck 1245 - parser now supports extended ASCII character set
566     (up to ASCII code 255, i.e. includes now umlauts and accents)
567     - filename arguments in LSCP commands now allow to use escape
568     sequences, that is directly literal as one of: \', \", \\, \n, \r,
569     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
570     code value like \xf2) (fixes bug #24)
571 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
572     least one of their text-based parameters (i.e. name, description):
573     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
574     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
575     "SET DB_INSTRUMENT_DIRECTORY NAME",
576     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
577     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
578     "FIND DB_INSTRUMENT_DIRECTORIES"
579 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
580     occured, the unexpected character and the actually expected, possible
581     character(s), the latter only if less than 5 possibilities)
582 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
583     settings
584 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
585     of strings were treated as being one string containing commas
586     (fixes #57)
587 schoenebeck 1244
588 iliev 959 * Bug fixes:
589     - fixed crash occurring on certain LSCP scripts (Bug 39)
590 persson 1038 - another thread safety fix for lscp "load engine" and "set
591     channel audio output device"
592 iliev 1283 - fixed a crash which occurs when reassigning the same engine
593     on a sampler channel with connected MIDI device
594 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
595     device connected to a sampler channel to number less then or equal
596     to the index of the port to which the sampler channel is connected.
597 iliev 1296 - The previous bindings were not been disconnected when altering
598     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
599     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
600 iliev 1297 - The active stream/voice count statistic was incorrect.
601 iliev 1298 - notification events were not been sent for some sampler
602     channel changes
603 iliev 1305 - added default min and max values to restrict the number of allowed
604     audio output channels and MIDI input ports
605 iliev 1306 - the connection to the PCM interface is now closed when destroying
606     an audio output device
607 schoenebeck 1332 - files with slash in their path or filename could not be loaded
608 iliev 959
609 schoenebeck 1221 * test cases:
610     - updated and fixed (haven't been touched in a while)
611    
612 schoenebeck 937 Version 0.4.0 (24 November 2006)
613 persson 696
614 schoenebeck 697 * packaging changes:
615 capela 868 - changed deprecated copyright attribute to license; added ldconfig
616     to post-(un)install steps; added devel package for liblinuxsampler;
617     to linuxsampler.spec (RPM)
618 schoenebeck 697 - install necessary development header files for allowing 3rd party
619     applications to link against liblinuxsampler
620     - liblinuxsampler's API documentation can be generated with 'make docs'
621     (Doxygen required)
622 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
623     implementation (currently either an integer math solution or a
624     di-harmonic approximation), automatic detection can be overriden
625     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
626     configure script argument though (mandatory for cross-compilation)
627 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
628     provided some on his own (as CXXFLAGS)
629 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
630     messages
631 schoenebeck 852 - added compile time options to allow disabling the various audio and
632     MIDI drivers
633 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
634     (patch by Ebrahim Mayat)
635 schoenebeck 697
636 persson 696 * Gigasampler format engine:
637 schoenebeck 738 - extensive synthesis optimization
638     (reimplementation of EGs and LFO(s), removed synthesis parameter
639     prerendering and the synthesis parameter matrix in general, splitting
640     each audio fragment into subfragments now where each subfragment uses
641 persson 830 constant pitch and filter coefficients. The volume coefficient is
642     linearly interpolated inside a subfragment, unless
643     --disable-interpolate-volume is set.)
644 persson 696 - fine tuning of the EG modulation parameters
645 persson 729 - improved filter cutoff calculation by adding support for the
646     following gig parameters: Cutoff freq (used when no cutoff
647     controller is defined), Control invert, Minimum cutoff, Velocity
648 persson 791 curve and Velocity range. The keyboard tracking now scales
649     cutoff frequency instead of resonance.
650 persson 877 - added support for gig parameter Resonance.
651 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
652 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
653     which can be overridden with --enable-global-attenuation
654 persson 783 - EG fixes: made the length of "attack hold" stage more
655     accurate. Release stage can now start before attack stage
656 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
657     time now has a minimal value to prevent clicks.
658 persson 799 - fixed pitch changes larger than one octave
659 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
660     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
661     all modes can be altered via standard GM messages, that is CC5 for
662     altering portamento time, CC65 for enabling / disabling portamento
663     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
664 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
665     parameter) and crossfade
666 persson 831 - added support for the "attenuation controller threshold" gig
667     parameter
668 persson 832 - added smoothing of volume changes caused by control change
669     messages
670 persson 865 - sample loop parameters are now taken from the DimensionRegion
671     instead of the wave chunk
672     - fixed keyswitching for v3 gigs with a number of keyswitch splits
673     not equal to a power of two
674 persson 877 - reimplementation of the filter algorithm. The new filter is more
675     accurate and supports all gig filter types, including bandreject
676     and lowpass turbo.
677 persson 903 - real support for 24 bit samples - samples are not truncated to
678     16 bits anymore
679     - support for aftertouch (channel pressure, not polyphonic
680     aftertouch)
681 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
682     amplifying from 0)
683 persson 696
684 schoenebeck 711 * LSCP server:
685     - fixed application exit on broken pipe error (fixes bug #20)
686 iliev 793 - fixed the notification messages delay due to lack of
687     network activity (fixes bug #26)
688 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
689     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
690 schoenebeck 711
691 schoenebeck 838 * audio driver:
692     - added aRts audio output driver (by no means RT safe)
693    
694 schoenebeck 775 * MIDI driver:
695     - fixed legacy sysex code which caused dispatching of MIDI SysEx
696     messages several times instead of once
697 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
698     for events (i.e. for offline rendering based MIDI drivers)
699 persson 922 - added checks for bad MIDI data
700 schoenebeck 775
701 schoenebeck 900 * linuxsampler application:
702     - show available sampler engine types on startup
703    
704 schoenebeck 705 * general changes:
705     - support for muting sampler channels and solo mode of the same, two new
706     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
707     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
708     introduced for this, the behavior is the same like on a mixer console
709 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
710     --enable-process-muted-channels which can be used to enable the
711     processing of muted channels.
712 iliev 777 - support for sostenuto pedal
713 iliev 779 - support for monitoring the total number of active voices
714 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
715     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
716 persson 835 - fixed some memory management errors
717 persson 841 - fixed some concurrency problems that could lead to crashes when
718     LSCP commands were executed
719 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
720     sampler channel (fixes bug #36)
721 schoenebeck 705
722 schoenebeck 692 Version 0.3.3 (15 July 2005)
723 schoenebeck 686
724     * packaging changes:
725     - fixed compilation with gcc 4.0
726    
727 schoenebeck 687 * Gigasampler format engine:
728     - LFO preprocessing was performed even though the respective LFO was
729     disabled by the instrument patch (minor efficiency fix)
730 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
731     for volume ramp downs in the same fragment (needed for current voice
732     stealing implementation) then simply inform the user with a warning
733     about possible click sounds and reduce the volume ramp down
734     appropriately instead of cancelling the audio device connection
735 schoenebeck 687
736 schoenebeck 677 Version 0.3.2 (24 June 2005)
737 schoenebeck 609
738     * packaging changes:
739     - updated autotools build files to compile on OS X
740     (conditional compilation of CoreMIDI and MidiShare drivers)
741 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
742     './configure --disable-asm' (definitely not recommended)
743 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
744     - require automake (>= 1.5) for 'make -f Makefile.cvs'
745     (due to 'dist-bzip2' automake option)
746 schoenebeck 649
747     * Gigasampler format engine:
748     - support for the gig parameters for "release velocity response" curves
749     - fine tuning of the EGADSR envelope
750     - volume of release triggered samples now depends on note-on velocity,
751     note length and gig parameter "release trigger decay" instead of
752     note-off velocity.
753 schoenebeck 663 - revised voice stealing
754     (fixes crash and endless loop caused by voice stealing)
755 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
756 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
757     instead of when the respective voice is actually launched
758     (fixes undefined behavior if stolen voices belonged to a key group -
759     this case was followed by a "killed voice survived" error message)
760 schoenebeck 669 - fixed minor issue with null/silence samples
761     (those stole voices even though they don't need a voice at all which
762     resulted in "voice stealing didn't work out" messages)
763 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
764     instrument or audio output device change
765 schoenebeck 654
766 schoenebeck 620 * LSCP server:
767 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
768 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
769 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
770 schoenebeck 609
771 schoenebeck 668 * linuxsampler application:
772     - added command line parameters --lscp-addr and --lscp-port to override
773     default IP address and port of LSCP server
774    
775 schoenebeck 579 Version 0.3.1 (24 May 2005)
776    
777     * initial release
