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

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

210     after MIDI/audio device creation failure
211 iliev 2012

213 schoenebeck 1599
214 schoenebeck 1639 * packaging changes:
215     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

233 schoenebeck 1639
234 schoenebeck 1601 * general changes:
235     - bugfix: on some POSIX systems instrument editor plugins refused to

237     (fixes bug #70, patch by Ronald Baljeu)
238 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
239     plugin DLL on Windows systems failed
240 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
241     - optimized the SynchronizedConfig class so it doesn't wait
242     unnecessarily long after an update
243 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off

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

250     implementation, which is usually faster)
251 persson 1748 - fixes for audio drivers with varying buffer sizes
252 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
253     VST plugin

260 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
261     be switched on by command line option "--stacktrace" (the automatic
262     stacktrace mechanism seems to be broken on most systems at the moment)
263 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
264     a pointer to the launched InstrumentEditor object
265 schoenebeck 1876 - added optional 3rd party user data parameter for following
266     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
267     InstrumentEditor::Launch(),

269 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
270     model more strictly
271 persson 1895 - fixes for using large audio device buffers
272 persson 1951 - Windows: add the installation directory to the DLL search path

275 schoenebeck 1601
276 schoenebeck 1599 * audio driver:
277     - removed the nonsense audio channel constraint (which was hard coded to
278     max. 100 audio channels) for most audio drivers
279 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
280     opposed to the LSCP specs
281 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
282     reflected the wrong value
283 persson 1644 - fixed a memory management bug in ASIO driver
284 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

286 persson 1748 jack_client_new
287 iliev 1829 - added (experimental) CoreAudio driver
288 persson 1888 - applied old fixes to the ASIO driver that were included in the
289     previous binary release but accidentally never committed to CVS
290     (fixes #117)
291 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
292     win64)
293 persson 1895 - VST: added support for sample rate and buffer size changes
294     - VST: close editor (Fantasia) when the VST is removed

303     AudioChannel::CopyTo() methods using GCC vector exensions
304     (if available)
305 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
306     exception when getting parameters from a disconnected device
307 schoenebeck 1599
308 persson 1651 * MIDI driver:
309     - added JACK MIDI driver
310 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

312     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
313 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
314 persson 1887 CoreMidi or AU
315 persson 1889 - fixed mingw-w64 compilation error in MME driver

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

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

440 schoenebeck 1560 Version 0.5.1 (6 December 2007)
441 schoenebeck 1454
442     * packaging changes:
443     - added autoconf checks for pthread library
444     - added autoconf check for pthread bug found on certain NPTL-enabled
445     glibc versions (see Gentoo bug report #194076)
446 senoner 1502 - added autoconf checks for MS Windows
447 schoenebeck 1454
448 persson 1455 * general changes:
449     - bugfix: the thread used by an editor plugin didn't die when the
450     editor closed
451 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
452     out all the space. operator--() did not apply size_mask after
453     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
454     order to avoid problems with the _NonVolatileReader functions.
455     - bugfix: Stream.h: added a missing divide by BytesPerSample in
456     GetWriteSpace(). Since this function is currently only used in
457     the stream's qsort() compare function, it didn't trigger any
458     bugs.
459     - Resampler.h, Synthesizer.h: cubic interpolation now works in
460     24bit mode too. Faster method to read 24bit words on little
461     endian machines (x86): replaced 3 byte reads + shifts with a 1
462     unaligned 32bit read and shift
463     - experimental support for MS Windows (MIDI input via MME, AUDIO
464     output via ASIO)
465     - made handling of SIGINT signal (Ctrl-C) a bit more robust
466 iliev 1541 - support for monitoring the total number of active disk streams
467     (new LSCP commands: GET TOTAL_STREAM_COUNT,
468     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
469 persson 1455
470 senoner 1500 * AUDIO driver:
471 persson 1534 - added Windows ASIO low latency audio driver
472 senoner 1500
473 senoner 1485 * MIDI driver:
474 schoenebeck 1495 - added MME Windows MIDI driver
475 senoner 1485
476 schoenebeck 1471 * LSCP server:
477     - added support for Windows style path / filenames, however with
478     forward slash path separators instead of backslash
479     (i.e. "C:/foo/bar.gig")
480 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
481     apostrophes as well
482 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
483     "LIST FILE INSTRUMENTS <file>" and
484     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
485     about an arbitrary instrument file on the system where the sampler is
486     running on
487 schoenebeck 1471
488 schoenebeck 1424 Version 0.5.0 (15 October 2007)
489 schoenebeck 947
490 schoenebeck 1065 * packaging changes:
491 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
492     API header files anymore
493 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
494     the Doxygen API documentation (explicitly listed in Doxyfile.in)
495 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
496     capable to execute our autoconf environment, thus no need anymore
497     to maintain the compile time configuration file (osx/version.h) for
498     OSX manually (patch by Toshi Nagata)
499 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
500     parameters
501 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
502     C++ API header files, all implementation internal global definitions
503     are now in global_private.h
504     - atomic.h is not exposed to the C++ API anymore
505     - no need to include config.h anymore for using LS's API header files
506     - fixed warnings in API doc generation
507 schoenebeck 1065
508 schoenebeck 947 * general changes:
509     - replaced the old, confusing MIDI program change mechanism by a
510     flexible MIDI instrument mapper which allows to map arbitrary
511 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
512 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
513     loaded on the respective channel when such MIDI program change
514     messages arrive, beside that, each entry allows to define a life-time
515     strategy for the instrument, so the user can define whether the
516     instrument should i.e. be permanently loaded (to be able to switch
517     quickly among sounds) or i.e. loaded just on demand when the
518     respective program change arrives (to safe RAM space), as well as a
519     global volume factor for each entry, so the user can adjust the volume
520     dynamic of his mapped instrument collection without having to modify
521 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
522     MIDI instrument maps and assign each sampler channel individually
523     a certain map, so that i.e. separation of normal instruments and
524     drumkits is possible
525 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
526     MIDI instrument maps, MIDI instruments, FX sends, global volume.
527 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
528     due to a constant size RingBuffer FIFO which is now replaced by a
529     dynamic (unlimited) size std::list FIFO
530 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
531     output channels for being processed by external effect processors
532     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
533     controllers
534 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
535 iliev 1130 - Implemented new, improved notification system
536 schoenebeck 1149 - fixed compilation errors regarding OSX
537     (patch by Toshi Nagata)
538 iliev 1161 - implemented instruments database
539 iliev 1345 - added support for escape sequences to the instruments database
540 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
541     within the sampler's process (by using instrument editor plugins),
542     you'll notice the new "Registered instrument editors:" message on
543 schoenebeck 1407 startup, added a new LSCP command:
544     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
545 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
546     given sampler channel, the plugin path can be overridden at compile
547     time with ./configure --enable-plugin-dir=/some/dir
548 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
549     in the sampler's process to safely edit instruments while playing
550     without a crash (hopefully) by either suspending single regions
551     wherever possible or if unavoidable whole engine(s)
552 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
553     policy and priority on thread level, set a minimum stack size for
554     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
555     threads simply inherited properties of starting thread instead of
556     setting their own policy and priority
557 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
558     main process did not wait for the stack trace process to finish
559     its output
560 persson 1248 - fixed some minor memory leaks
561 schoenebeck 1259 - reenabled assembly features support, at the moment only for
562     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
563 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
564     register, to avoid relocations in the text segment at runtime)
565 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
566 schoenebeck 947
567     * MIDI driver:
568     - dispatch bank select (MSB and LSB) messages
569    
570 schoenebeck 1049 * audio driver:
571     - the ALSA audio output driver parameters now reflect the correct
572     parameter value ranges for the respective selected sound card
573     (patch by Till Wimmer, a bit fixed and extended)
574    
575 persson 951 * Gigasampler format engine:
576     - if a filter is used and EG2 finishes before EG1, let the voice
577     die when EG2 has finished (this fixes a problem with clicks and
578     voice starvation for some gigs)
579 persson 1038 - playback is no longer disabled during instrument loading
580     - all notes playing on a channel that changes its instrument keep
581     playing with the old instrument until they get a note off
582     command
583 persson 1039 - EG fix: a release value of zero could cause noises or crash
584 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
585 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
586     above max sustain level, which means that there is a decay phase
587     even if sustain is 100%
588 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
589     noises or crashes
590 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
591 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
592     supplied to the configure script (fixes #46)
593 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
594     instead of a fix value
595 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
596     127 (solo mode) only kill voices if the respective mode really
597     changed
598 persson 951
599 schoenebeck 1244 * LSCP server:
600     - fixed compile time error for old Bison versions
601     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
602 schoenebeck 1245 - parser now supports extended ASCII character set
603     (up to ASCII code 255, i.e. includes now umlauts and accents)
604     - filename arguments in LSCP commands now allow to use escape
605     sequences, that is directly literal as one of: \', \", \\, \n, \r,
606     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
607     code value like \xf2) (fixes bug #24)
608 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
609     least one of their text-based parameters (i.e. name, description):
610     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
611     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
612     "SET DB_INSTRUMENT_DIRECTORY NAME",
613     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
614     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
615     "FIND DB_INSTRUMENT_DIRECTORIES"
616 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
617     occured, the unexpected character and the actually expected, possible
618     character(s), the latter only if less than 5 possibilities)
619 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
620     settings
621 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
622     of strings were treated as being one string containing commas
623     (fixes #57)
624 schoenebeck 1244
625 iliev 959 * Bug fixes:
626     - fixed crash occurring on certain LSCP scripts (Bug 39)
627 persson 1038 - another thread safety fix for lscp "load engine" and "set
628     channel audio output device"
629 iliev 1283 - fixed a crash which occurs when reassigning the same engine
630     on a sampler channel with connected MIDI device
631 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
632     device connected to a sampler channel to number less then or equal
633     to the index of the port to which the sampler channel is connected.
634 iliev 1296 - The previous bindings were not been disconnected when altering
635     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
636     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
637 iliev 1297 - The active stream/voice count statistic was incorrect.
638 iliev 1298 - notification events were not been sent for some sampler
639     channel changes
640 iliev 1305 - added default min and max values to restrict the number of allowed
641     audio output channels and MIDI input ports
642 iliev 1306 - the connection to the PCM interface is now closed when destroying
643     an audio output device
644 schoenebeck 1332 - files with slash in their path or filename could not be loaded
645 iliev 959
646 schoenebeck 1221 * test cases:
647     - updated and fixed (haven't been touched in a while)
648    
649 schoenebeck 937 Version 0.4.0 (24 November 2006)
650 persson 696
651 schoenebeck 697 * packaging changes:
652 capela 868 - changed deprecated copyright attribute to license; added ldconfig
653     to post-(un)install steps; added devel package for liblinuxsampler;
654     to linuxsampler.spec (RPM)
655 schoenebeck 697 - install necessary development header files for allowing 3rd party
656     applications to link against liblinuxsampler
657     - liblinuxsampler's API documentation can be generated with 'make docs'
658     (Doxygen required)
659 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
660     implementation (currently either an integer math solution or a
661     di-harmonic approximation), automatic detection can be overriden
662     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
663     configure script argument though (mandatory for cross-compilation)
664 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
665     provided some on his own (as CXXFLAGS)
666 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
667     messages
668 schoenebeck 852 - added compile time options to allow disabling the various audio and
669     MIDI drivers
670 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
671     (patch by Ebrahim Mayat)
672 schoenebeck 697
673 persson 696 * Gigasampler format engine:
674 schoenebeck 738 - extensive synthesis optimization
675     (reimplementation of EGs and LFO(s), removed synthesis parameter
676     prerendering and the synthesis parameter matrix in general, splitting
677     each audio fragment into subfragments now where each subfragment uses
678 persson 830 constant pitch and filter coefficients. The volume coefficient is
679     linearly interpolated inside a subfragment, unless
680     --disable-interpolate-volume is set.)
681 persson 696 - fine tuning of the EG modulation parameters
682 persson 729 - improved filter cutoff calculation by adding support for the
683     following gig parameters: Cutoff freq (used when no cutoff
684     controller is defined), Control invert, Minimum cutoff, Velocity
685 persson 791 curve and Velocity range. The keyboard tracking now scales
686     cutoff frequency instead of resonance.
687 persson 877 - added support for gig parameter Resonance.
688 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
689 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
690     which can be overridden with --enable-global-attenuation
691 persson 783 - EG fixes: made the length of "attack hold" stage more
692     accurate. Release stage can now start before attack stage
693 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
694     time now has a minimal value to prevent clicks.
695 persson 799 - fixed pitch changes larger than one octave
696 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
697     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
698     all modes can be altered via standard GM messages, that is CC5 for
699     altering portamento time, CC65 for enabling / disabling portamento
700     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
701 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
702     parameter) and crossfade
703 persson 831 - added support for the "attenuation controller threshold" gig
704     parameter
705 persson 832 - added smoothing of volume changes caused by control change
706     messages
707 persson 865 - sample loop parameters are now taken from the DimensionRegion
708     instead of the wave chunk
709     - fixed keyswitching for v3 gigs with a number of keyswitch splits
710     not equal to a power of two
711 persson 877 - reimplementation of the filter algorithm. The new filter is more
712     accurate and supports all gig filter types, including bandreject
713     and lowpass turbo.
714 persson 903 - real support for 24 bit samples - samples are not truncated to
715     16 bits anymore
716     - support for aftertouch (channel pressure, not polyphonic
717     aftertouch)
718 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
719     amplifying from 0)
720 persson 696
721 schoenebeck 711 * LSCP server:
722     - fixed application exit on broken pipe error (fixes bug #20)
723 iliev 793 - fixed the notification messages delay due to lack of
724     network activity (fixes bug #26)
725 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
726     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
727 schoenebeck 711
728 schoenebeck 838 * audio driver:
729     - added aRts audio output driver (by no means RT safe)
730    
731 schoenebeck 775 * MIDI driver:
732     - fixed legacy sysex code which caused dispatching of MIDI SysEx
733     messages several times instead of once
734 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
735     for events (i.e. for offline rendering based MIDI drivers)
736 persson 922 - added checks for bad MIDI data
737 schoenebeck 775
738 schoenebeck 900 * linuxsampler application:
739     - show available sampler engine types on startup
740    
741 schoenebeck 705 * general changes:
742     - support for muting sampler channels and solo mode of the same, two new
743     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
744     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
745     introduced for this, the behavior is the same like on a mixer console
746 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
747     --enable-process-muted-channels which can be used to enable the
748     processing of muted channels.
749 iliev 777 - support for sostenuto pedal
750 iliev 779 - support for monitoring the total number of active voices
751 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
752     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
753 persson 835 - fixed some memory management errors
754 persson 841 - fixed some concurrency problems that could lead to crashes when
755     LSCP commands were executed
756 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
757     sampler channel (fixes bug #36)
758 schoenebeck 705
759 schoenebeck 692 Version 0.3.3 (15 July 2005)
760 schoenebeck 686
761     * packaging changes:
762     - fixed compilation with gcc 4.0
763    
764 schoenebeck 687 * Gigasampler format engine:
765     - LFO preprocessing was performed even though the respective LFO was
766     disabled by the instrument patch (minor efficiency fix)
767 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
768     for volume ramp downs in the same fragment (needed for current voice
769     stealing implementation) then simply inform the user with a warning
770     about possible click sounds and reduce the volume ramp down
771     appropriately instead of cancelling the audio device connection
772 schoenebeck 687
773 schoenebeck 677 Version 0.3.2 (24 June 2005)
774 schoenebeck 609
775     * packaging changes:
776     - updated autotools build files to compile on OS X
777     (conditional compilation of CoreMIDI and MidiShare drivers)
778 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
779     './configure --disable-asm' (definitely not recommended)
780 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
781     - require automake (>= 1.5) for 'make -f Makefile.cvs'
782     (due to 'dist-bzip2' automake option)
783 schoenebeck 649
784     * Gigasampler format engine:
785     - support for the gig parameters for "release velocity response" curves
786     - fine tuning of the EGADSR envelope
787     - volume of release triggered samples now depends on note-on velocity,
788     note length and gig parameter "release trigger decay" instead of
789     note-off velocity.
790 schoenebeck 663 - revised voice stealing
791     (fixes crash and endless loop caused by voice stealing)
792 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
793 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
794     instead of when the respective voice is actually launched
795     (fixes undefined behavior if stolen voices belonged to a key group -
796     this case was followed by a "killed voice survived" error message)
797 schoenebeck 669 - fixed minor issue with null/silence samples
798     (those stole voices even though they don't need a voice at all which
799     resulted in "voice stealing didn't work out" messages)
800 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
801     instrument or audio output device change
802 schoenebeck 654
803 schoenebeck 620 * LSCP server:
804 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
805 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
806 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
807 schoenebeck 609
808 schoenebeck 668 * linuxsampler application:
809     - added command line parameters --lscp-addr and --lscp-port to override
810     default IP address and port of LSCP server
811    
812 schoenebeck 579 Version 0.3.1 (24 May 2005)
813
