16 persson 2086
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
23     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory

27     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
28     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
29     note (in this implementation of the sampler its simply hard routed to
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)

171 schoenebeck 1599
172 schoenebeck 1639 * packaging changes:

191 schoenebeck 1639
192 schoenebeck 1601 * general changes:
193     - bugfix: on some POSIX systems instrument editor plugins refused to

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

235     - removed the nonsense audio channel constraint (which was hard coded to
236     max. 100 audio channels) for most audio drivers
237 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
238     opposed to the LSCP specs
239 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
240     reflected the wrong value

244 persson 1748 jack_client_new
245 iliev 1829 - added (experimental) CoreAudio driver
246 persson 1888 - applied old fixes to the ASIO driver that were included in the
247     previous binary release but accidentally never committed to CVS
248     (fixes #117)
249 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
250     win64)
251 persson 1895 - VST: added support for sample rate and buffer size changes
252     - VST: close editor (Fantasia) when the VST is removed

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

285 persson 1908 - work-around for missing fnmatch function on Windows to make
286     instrument database compilable
287 schoenebeck 1930 - added instrument database support on Windows
288     works with both standalone mode and VST plugin.
289     the instruments DB file is located in
290     %USERPROFILE%\.linuxsampler\instruments.db which allows different
291     databases for each windows user
292     if no DB is present it automatically creates the .linuxsampler subdir
293     and then creates an empty DB
294 persson 1943 - fixed recursive import, which was broken on Windows
295 iliev 1603
296 persson 1644 * Gigasampler format engine:
297     - fixed a memory leak that could happen when a channel was deleted
298     while notes were playing
299 persson 1646 - made it possible to load an instrument even if the audio thread
300     isn't running
301 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
302     enough for piano gigs with pedal noise samples
303 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
304     respective FX send MIDI controller was used
305 schoenebeck 1724 - added support for GM global device volume SysEx message
306 schoenebeck 1762 (can be selected at compile time to either apply globally to the
307     whole sampler [default] or only to the sampler channels that are
308     connected to the respective MIDI input port the SysEx message arrived
309     on)
310 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
311     sometimes wrongly killed in the same buffer, causing no sound to
312     be played
313 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
314     which is usally used to switch a part between chromatic sounds and
315     drumkit sounds (as opposed to their common default setting of MIDI
316     part 10 being a drumkit part and all other ones chromatic parts), in
317     LS however one can switch between the first 16 MIDI instrument maps
318     defined for the sampler
319 persson 1764 - made it possible to create multiple sample channels even if the
320     audio thread isn't running
321 persson 1844 - fixed crash when removing channel with active voices (#116)
322 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
323     un-cache the respective sample if it's really not used by any
324     sampler engine anymore
325     - re-cache samples in case they were changed by an instrument editor,
326     e.g. when a sample was added while playing (#82)
327 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
328     same time stamp as the voice's note-on event and occured both in the
329     same audio fragment cycle (fixes bug #112)
330 persson 1858 - added support for the "fine tune" and "pitch bend range"
331     instrument-level gig parameters
332     - fixed minor artifacts in pitch bend handling
333 schoenebeck 1860 - added support for GS Reset SysEx message
334 persson 1862 - allow gig files to use unlimited downward pitch shifting
335     - added a limit check for upward pitch shifting
336 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
337     note was silent
338 persson 1923 - fixed crash happening when a pitch bend event arrived at the
339     same time a new instrument was loading
340 persson 1644
341 schoenebeck 1687 * LSCP server:
342     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
343     react on MIDI data arriving on certain sampler channels (so far only
344     Note-On and Note-Off events are sent via this LSCP event)
345 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
346     react on MIDI data arriving on certain MIDI input devices (so far only
347     Note-On and Note-Off events are sent via this LSCP event)
348 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
349     SET DB_INSTRUMENT FILE_PATH
350 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
351     frontends to send MIDI messages to specific sampler channel
352     - added two additional fields to GET FILE INSTRUMENT INFO command -
353     KEY_BINDINGS and KEYSWITCH_BINDINGS
354 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
355     was incorrect
356 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
357 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
358     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
359     be triggered respectively
360     - added new LSCP command "SET STREAMS" to globally alter the maximum
361     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
362     which will be triggered respectively
363 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
364     a gigedit file dialog is opened)
365 iliev 1848 - close all connections when LSCPServer is deleted
366 iliev 1882 - hard close of all sockets on exit

385 iliev 1847 - fixed crash when changing the audio output device of a sampler
386     channel with loaded instrument and start playing notes
387 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
388 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
389     PowerPC, which probably could cause crashes on that platform
390 persson 1889 - fixed a memory management error which could cause a crash when a
391     plugin was unloaded
392 persson 1896 - bugfix: two private structs had the same name, which could cause
393     problems if the linker chose the wrong constructor
394 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
395     Windows

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