9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X

20 persson 2208 - Mac OS X: Makefile fix for the install-strip target
21 persson 2086
22     * general changes:
23 iliev 2012 - Refactoring: moved the independent code from
24     the Gigasampler format engine to base classes
25 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
26     respective profiling code is currently broken
27 schoenebeck 2053 - Introduced support for optional environment variable
28     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29     where the sampler shall look for instrument editor plugins

32     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34     note (in this implementation of the sampler its simply hard routed to
35     the 1st effect send of the sampler channel, no matter what the actual
36     effect type is)
37     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 2nd effect send of the sampler channel, no matter what the actual
40     effect type is)

204 schoenebeck 1599
205 schoenebeck 1639 * packaging changes:
206     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

224 schoenebeck 1639
225 schoenebeck 1601 * general changes:
226     - bugfix: on some POSIX systems instrument editor plugins refused to

228     (fixes bug #70, patch by Ronald Baljeu)
229 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
230     plugin DLL on Windows systems failed

238 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
239 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

241     implementation, which is usually faster)
242 persson 1748 - fixes for audio drivers with varying buffer sizes
243 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
244     VST plugin

251 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
252     be switched on by command line option "--stacktrace" (the automatic
253     stacktrace mechanism seems to be broken on most systems at the moment)
254 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
255     a pointer to the launched InstrumentEditor object
256 schoenebeck 1876 - added optional 3rd party user data parameter for following
257     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
258     InstrumentEditor::Launch(),

277 persson 1748 jack_client_new
278 iliev 1829 - added (experimental) CoreAudio driver
279 persson 1888 - applied old fixes to the ASIO driver that were included in the
280     previous binary release but accidentally never committed to CVS
281     (fixes #117)
282 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
283     win64)
284 persson 1895 - VST: added support for sample rate and buffer size changes
285     - VST: close editor (Fantasia) when the VST is removed

294     AudioChannel::CopyTo() methods using GCC vector exensions
295     (if available)
296 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
297     exception when getting parameters from a disconnected device
298 schoenebeck 1599
299 persson 1651 * MIDI driver:
300     - added JACK MIDI driver
301 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
302     want to (mis)use it for some purpose ("fixed" in all current MIDI
303     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
304 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
305 persson 1887 CoreMidi or AU
306 persson 1889 - fixed mingw-w64 compilation error in MME driver

318 persson 1908 - work-around for missing fnmatch function on Windows to make
319     instrument database compilable
320 schoenebeck 1930 - added instrument database support on Windows
321     works with both standalone mode and VST plugin.
322     the instruments DB file is located in
323     %USERPROFILE%\.linuxsampler\instruments.db which allows different
324     databases for each windows user
325     if no DB is present it automatically creates the .linuxsampler subdir
326     and then creates an empty DB
327 persson 1943 - fixed recursive import, which was broken on Windows
328 iliev 1603
329 persson 1644 * Gigasampler format engine:
330     - fixed a memory leak that could happen when a channel was deleted
331     while notes were playing
332 persson 1646 - made it possible to load an instrument even if the audio thread
333     isn't running
334 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
335     enough for piano gigs with pedal noise samples
336 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
337     respective FX send MIDI controller was used
338 schoenebeck 1724 - added support for GM global device volume SysEx message
339 schoenebeck 1762 (can be selected at compile time to either apply globally to the
340     whole sampler [default] or only to the sampler channels that are
341     connected to the respective MIDI input port the SysEx message arrived
342     on)
343 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
344     sometimes wrongly killed in the same buffer, causing no sound to
345     be played
346 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
347     which is usally used to switch a part between chromatic sounds and
348     drumkit sounds (as opposed to their common default setting of MIDI
349     part 10 being a drumkit part and all other ones chromatic parts), in
350     LS however one can switch between the first 16 MIDI instrument maps
351     defined for the sampler
352 persson 1764 - made it possible to create multiple sample channels even if the
353     audio thread isn't running
354 persson 1844 - fixed crash when removing channel with active voices (#116)
355 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
356     un-cache the respective sample if it's really not used by any
357     sampler engine anymore
358     - re-cache samples in case they were changed by an instrument editor,
359     e.g. when a sample was added while playing (#82)
360 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
361     same time stamp as the voice's note-on event and occured both in the
362     same audio fragment cycle (fixes bug #112)
363 persson 1858 - added support for the "fine tune" and "pitch bend range"
364     instrument-level gig parameters
365     - fixed minor artifacts in pitch bend handling
366 schoenebeck 1860 - added support for GS Reset SysEx message
367 persson 1862 - allow gig files to use unlimited downward pitch shifting
368     - added a limit check for upward pitch shifting
369 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
370     note was silent
371 persson 1923 - fixed crash happening when a pitch bend event arrived at the
372     same time a new instrument was loading
373 persson 1644
374 schoenebeck 1687 * LSCP server:
375     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
376     react on MIDI data arriving on certain sampler channels (so far only
377     Note-On and Note-Off events are sent via this LSCP event)
378 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
379     react on MIDI data arriving on certain MIDI input devices (so far only
380     Note-On and Note-Off events are sent via this LSCP event)
381 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
382     SET DB_INSTRUMENT FILE_PATH
383 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
384     frontends to send MIDI messages to specific sampler channel
385     - added two additional fields to GET FILE INSTRUMENT INFO command -
386     KEY_BINDINGS and KEYSWITCH_BINDINGS
387 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
388     was incorrect
389 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
390 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
391     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
392     be triggered respectively
393     - added new LSCP command "SET STREAMS" to globally alter the maximum
394     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
395     which will be triggered respectively
396 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
397     a gigedit file dialog is opened)
398 iliev 1848 - close all connections when LSCPServer is deleted
399 iliev 1882 - hard close of all sockets on exit
400 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
401     driver
402 schoenebeck 1687
403 iliev 1761 * Bug fixes:
404     - fixed a crash which occurs when removing a sampler channel waiting
405     to start instrument loading after another channel
406 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
407     instrument loading in progress (bug #113)
408 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
409     instrument with PERSISTENT load mode
410 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
411     - fixed memory leaks when issuing the following LSCP commands:

413     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
414     GET MIDI_INPUT_DRIVER INFO
415     GET MIDI_INPUT_DRIVER_PARAMETER INFO
416     - fixed possible compilation error when sqlite is not present
417 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
418 iliev 1847 - fixed crash when changing the audio output device of a sampler
419     channel with loaded instrument and start playing notes
420 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
421 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
422     PowerPC, which probably could cause crashes on that platform
423 persson 1889 - fixed a memory management error which could cause a crash when a
424     plugin was unloaded
425 persson 1896 - bugfix: two private structs had the same name, which could cause
426     problems if the linker chose the wrong constructor
427 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
428     Windows

431 schoenebeck 1560 Version 0.5.1 (6 December 2007)
432 schoenebeck 1454
433     * packaging changes:
434     - added autoconf checks for pthread library
435     - added autoconf check for pthread bug found on certain NPTL-enabled
436     glibc versions (see Gentoo bug report #194076)
437 senoner 1502 - added autoconf checks for MS Windows
438 schoenebeck 1454
439 persson 1455 * general changes:
440     - bugfix: the thread used by an editor plugin didn't die when the
441     editor closed
442 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
443     out all the space. operator--() did not apply size_mask after
444     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
445     order to avoid problems with the _NonVolatileReader functions.
446     - bugfix: Stream.h: added a missing divide by BytesPerSample in
447     GetWriteSpace(). Since this function is currently only used in
448     the stream's qsort() compare function, it didn't trigger any
449     bugs.
450     - Resampler.h, Synthesizer.h: cubic interpolation now works in
451     24bit mode too. Faster method to read 24bit words on little
452     endian machines (x86): replaced 3 byte reads + shifts with a 1
453     unaligned 32bit read and shift
454     - experimental support for MS Windows (MIDI input via MME, AUDIO
455     output via ASIO)
456     - made handling of SIGINT signal (Ctrl-C) a bit more robust
457 iliev 1541 - support for monitoring the total number of active disk streams
458     (new LSCP commands: GET TOTAL_STREAM_COUNT,
459     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
460 persson 1455
461 senoner 1500 * AUDIO driver:
462 persson 1534 - added Windows ASIO low latency audio driver
463 senoner 1500
464 senoner 1485 * MIDI driver:
465 schoenebeck 1495 - added MME Windows MIDI driver
466 senoner 1485
467 schoenebeck 1471 * LSCP server:
468     - added support for Windows style path / filenames, however with
469     forward slash path separators instead of backslash
470     (i.e. "C:/foo/bar.gig")
471 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
472     apostrophes as well
473 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
474     "LIST FILE INSTRUMENTS <file>" and
475     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
476     about an arbitrary instrument file on the system where the sampler is
477     running on
478 schoenebeck 1471
479 schoenebeck 1424 Version 0.5.0 (15 October 2007)
480 schoenebeck 947
481 schoenebeck 1065 * packaging changes:
482 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
483     API header files anymore
484 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
485     the Doxygen API documentation (explicitly listed in Doxyfile.in)
486 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
487     capable to execute our autoconf environment, thus no need anymore
488     to maintain the compile time configuration file (osx/version.h) for
489     OSX manually (patch by Toshi Nagata)
490 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
491     parameters
492 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
493     C++ API header files, all implementation internal global definitions
494     are now in global_private.h
495     - atomic.h is not exposed to the C++ API anymore
496     - no need to include config.h anymore for using LS's API header files
497     - fixed warnings in API doc generation
498 schoenebeck 1065
499 schoenebeck 947 * general changes:
500     - replaced the old, confusing MIDI program change mechanism by a
501     flexible MIDI instrument mapper which allows to map arbitrary
502 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
503 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
504     loaded on the respective channel when such MIDI program change
505     messages arrive, beside that, each entry allows to define a life-time
506     strategy for the instrument, so the user can define whether the
507     instrument should i.e. be permanently loaded (to be able to switch
508     quickly among sounds) or i.e. loaded just on demand when the
509     respective program change arrives (to safe RAM space), as well as a
510     global volume factor for each entry, so the user can adjust the volume
511     dynamic of his mapped instrument collection without having to modify
512 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
513     MIDI instrument maps and assign each sampler channel individually
514     a certain map, so that i.e. separation of normal instruments and
515     drumkits is possible
516 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
517     MIDI instrument maps, MIDI instruments, FX sends, global volume.
518 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
519     due to a constant size RingBuffer FIFO which is now replaced by a
520     dynamic (unlimited) size std::list FIFO
521 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
522     output channels for being processed by external effect processors
523     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
524     controllers
525 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
526 iliev 1130 - Implemented new, improved notification system
527 schoenebeck 1149 - fixed compilation errors regarding OSX
528     (patch by Toshi Nagata)
529 iliev 1161 - implemented instruments database
530 iliev 1345 - added support for escape sequences to the instruments database
531 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
532     within the sampler's process (by using instrument editor plugins),
533     you'll notice the new "Registered instrument editors:" message on
534 schoenebeck 1407 startup, added a new LSCP command:
535     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
536 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
537     given sampler channel, the plugin path can be overridden at compile
538     time with ./configure --enable-plugin-dir=/some/dir
539 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
540     in the sampler's process to safely edit instruments while playing
541     without a crash (hopefully) by either suspending single regions
542     wherever possible or if unavoidable whole engine(s)
543 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
544     policy and priority on thread level, set a minimum stack size for
545     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
546     threads simply inherited properties of starting thread instead of
547     setting their own policy and priority
548 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
549     main process did not wait for the stack trace process to finish
550     its output
551 persson 1248 - fixed some minor memory leaks
552 schoenebeck 1259 - reenabled assembly features support, at the moment only for
553     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
554 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
555     register, to avoid relocations in the text segment at runtime)
556 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
557 schoenebeck 947
558     * MIDI driver:
559     - dispatch bank select (MSB and LSB) messages
560    
561 schoenebeck 1049 * audio driver:
562     - the ALSA audio output driver parameters now reflect the correct
563     parameter value ranges for the respective selected sound card
564     (patch by Till Wimmer, a bit fixed and extended)
565    
566 persson 951 * Gigasampler format engine:
567     - if a filter is used and EG2 finishes before EG1, let the voice
568     die when EG2 has finished (this fixes a problem with clicks and
569     voice starvation for some gigs)
570 persson 1038 - playback is no longer disabled during instrument loading
571     - all notes playing on a channel that changes its instrument keep
572     playing with the old instrument until they get a note off
573     command
574 persson 1039 - EG fix: a release value of zero could cause noises or crash
575 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
576 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
577     above max sustain level, which means that there is a decay phase
578     even if sustain is 100%
579 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
580     noises or crashes
581 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
582 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
583     supplied to the configure script (fixes #46)
584 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
585     instead of a fix value
586 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
587     127 (solo mode) only kill voices if the respective mode really
588     changed
589 persson 951
590 schoenebeck 1244 * LSCP server:
591     - fixed compile time error for old Bison versions
592     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
593 schoenebeck 1245 - parser now supports extended ASCII character set
594     (up to ASCII code 255, i.e. includes now umlauts and accents)
595     - filename arguments in LSCP commands now allow to use escape
596     sequences, that is directly literal as one of: \', \", \\, \n, \r,
597     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
598     code value like \xf2) (fixes bug #24)
599 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
600     least one of their text-based parameters (i.e. name, description):
601     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
602     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
603     "SET DB_INSTRUMENT_DIRECTORY NAME",
604     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
605     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
606     "FIND DB_INSTRUMENT_DIRECTORIES"
607 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
608     occured, the unexpected character and the actually expected, possible
609     character(s), the latter only if less than 5 possibilities)
610 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
611     settings
612 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
613     of strings were treated as being one string containing commas
614     (fixes #57)
615 schoenebeck 1244
616 iliev 959 * Bug fixes:
617     - fixed crash occurring on certain LSCP scripts (Bug 39)
618 persson 1038 - another thread safety fix for lscp "load engine" and "set
619     channel audio output device"
620 iliev 1283 - fixed a crash which occurs when reassigning the same engine
621     on a sampler channel with connected MIDI device
622 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
623     device connected to a sampler channel to number less then or equal
624     to the index of the port to which the sampler channel is connected.
625 iliev 1296 - The previous bindings were not been disconnected when altering
626     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
627     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
628 iliev 1297 - The active stream/voice count statistic was incorrect.
629 iliev 1298 - notification events were not been sent for some sampler
630     channel changes
631 iliev 1305 - added default min and max values to restrict the number of allowed
632     audio output channels and MIDI input ports
633 iliev 1306 - the connection to the PCM interface is now closed when destroying
634     an audio output device
635 schoenebeck 1332 - files with slash in their path or filename could not be loaded
636 iliev 959
637 schoenebeck 1221 * test cases:
638     - updated and fixed (haven't been touched in a while)
639    
640 schoenebeck 937 Version 0.4.0 (24 November 2006)
641 persson 696
642 schoenebeck 697 * packaging changes:
643 capela 868 - changed deprecated copyright attribute to license; added ldconfig
644     to post-(un)install steps; added devel package for liblinuxsampler;
645     to linuxsampler.spec (RPM)
646 schoenebeck 697 - install necessary development header files for allowing 3rd party
647     applications to link against liblinuxsampler
648     - liblinuxsampler's API documentation can be generated with 'make docs'
649     (Doxygen required)
650 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
651     implementation (currently either an integer math solution or a
652     di-harmonic approximation), automatic detection can be overriden
653     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
654     configure script argument though (mandatory for cross-compilation)
655 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
656     provided some on his own (as CXXFLAGS)
657 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
658     messages
659 schoenebeck 852 - added compile time options to allow disabling the various audio and
660     MIDI drivers
661 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
662     (patch by Ebrahim Mayat)
663 schoenebeck 697
664 persson 696 * Gigasampler format engine:
665 schoenebeck 738 - extensive synthesis optimization
666     (reimplementation of EGs and LFO(s), removed synthesis parameter
667     prerendering and the synthesis parameter matrix in general, splitting
668     each audio fragment into subfragments now where each subfragment uses
669 persson 830 constant pitch and filter coefficients. The volume coefficient is
670     linearly interpolated inside a subfragment, unless
671     --disable-interpolate-volume is set.)
672 persson 696 - fine tuning of the EG modulation parameters
673 persson 729 - improved filter cutoff calculation by adding support for the
674     following gig parameters: Cutoff freq (used when no cutoff
675     controller is defined), Control invert, Minimum cutoff, Velocity
676 persson 791 curve and Velocity range. The keyboard tracking now scales
677     cutoff frequency instead of resonance.
678 persson 877 - added support for gig parameter Resonance.
679 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
680 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
681     which can be overridden with --enable-global-attenuation
682 persson 783 - EG fixes: made the length of "attack hold" stage more
683     accurate. Release stage can now start before attack stage
684 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
685     time now has a minimal value to prevent clicks.
686 persson 799 - fixed pitch changes larger than one octave
687 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
688     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
689     all modes can be altered via standard GM messages, that is CC5 for
690     altering portamento time, CC65 for enabling / disabling portamento
691     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
692 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
693     parameter) and crossfade
694 persson 831 - added support for the "attenuation controller threshold" gig
695     parameter
696 persson 832 - added smoothing of volume changes caused by control change
697     messages
698 persson 865 - sample loop parameters are now taken from the DimensionRegion
699     instead of the wave chunk
700     - fixed keyswitching for v3 gigs with a number of keyswitch splits
701     not equal to a power of two
702 persson 877 - reimplementation of the filter algorithm. The new filter is more
703     accurate and supports all gig filter types, including bandreject
704     and lowpass turbo.
705 persson 903 - real support for 24 bit samples - samples are not truncated to
706     16 bits anymore
707     - support for aftertouch (channel pressure, not polyphonic
708     aftertouch)
709 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
710     amplifying from 0)
711 persson 696
712 schoenebeck 711 * LSCP server:
713     - fixed application exit on broken pipe error (fixes bug #20)
714 iliev 793 - fixed the notification messages delay due to lack of
715     network activity (fixes bug #26)
716 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
717     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
718 schoenebeck 711
719 schoenebeck 838 * audio driver:
720     - added aRts audio output driver (by no means RT safe)
721    
722 schoenebeck 775 * MIDI driver:
723     - fixed legacy sysex code which caused dispatching of MIDI SysEx
724     messages several times instead of once
725 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
726     for events (i.e. for offline rendering based MIDI drivers)
727 persson 922 - added checks for bad MIDI data
728 schoenebeck 775
729 schoenebeck 900 * linuxsampler application:
730     - show available sampler engine types on startup
731    
732 schoenebeck 705 * general changes:
733     - support for muting sampler channels and solo mode of the same, two new
734     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
735     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
736     introduced for this, the behavior is the same like on a mixer console
737 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
738     --enable-process-muted-channels which can be used to enable the
739     processing of muted channels.
740 iliev 777 - support for sostenuto pedal
741 iliev 779 - support for monitoring the total number of active voices
742 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
743     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
744 persson 835 - fixed some memory management errors
745 persson 841 - fixed some concurrency problems that could lead to crashes when
746     LSCP commands were executed
747 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
748     sampler channel (fixes bug #36)
749 schoenebeck 705
750 schoenebeck 692 Version 0.3.3 (15 July 2005)
751 schoenebeck 686
752     * packaging changes:
753     - fixed compilation with gcc 4.0
754    
755 schoenebeck 687 * Gigasampler format engine:
756     - LFO preprocessing was performed even though the respective LFO was
757     disabled by the instrument patch (minor efficiency fix)
758 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
759     for volume ramp downs in the same fragment (needed for current voice
760     stealing implementation) then simply inform the user with a warning
761     about possible click sounds and reduce the volume ramp down
762     appropriately instead of cancelling the audio device connection
763 schoenebeck 687
764 schoenebeck 677 Version 0.3.2 (24 June 2005)
765 schoenebeck 609
766     * packaging changes:
767     - updated autotools build files to compile on OS X
768     (conditional compilation of CoreMIDI and MidiShare drivers)
769 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
770     './configure --disable-asm' (definitely not recommended)
771 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
772     - require automake (>= 1.5) for 'make -f Makefile.cvs'
773     (due to 'dist-bzip2' automake option)
774 schoenebeck 649
775     * Gigasampler format engine:
776     - support for the gig parameters for "release velocity response" curves
777     - fine tuning of the EGADSR envelope
778     - volume of release triggered samples now depends on note-on velocity,
779     note length and gig parameter "release trigger decay" instead of
780     note-off velocity.
781 schoenebeck 663 - revised voice stealing
782     (fixes crash and endless loop caused by voice stealing)
783 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
784 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
785     instead of when the respective voice is actually launched
786     (fixes undefined behavior if stolen voices belonged to a key group -
787     this case was followed by a "killed voice survived" error message)
788 schoenebeck 669 - fixed minor issue with null/silence samples
789     (those stole voices even though they don't need a voice at all which
790     resulted in "voice stealing didn't work out" messages)
791 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
792     instrument or audio output device change
793 schoenebeck 654
794 schoenebeck 620 * LSCP server:
795 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
796 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
797 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
798 schoenebeck 609
799 schoenebeck 668 * linuxsampler application:
800     - added command line parameters --lscp-addr and --lscp-port to override
801     default IP address and port of LSCP server
802    
803 schoenebeck 579 Version 0.3.1 (24 May 2005)
