  time (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
  ampeg_vel2release)

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4     - LV2 Persist + Files support (patch by David Robillard)
5    
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8    
9     * general changes:
10 iliev 2012 - Refactoring: moved the independent code from
11     the Gigasampler format engine to base classes
12 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
13     respective profiling code is currently broken
14 schoenebeck 2053 - Introduced support for optional environment variable
15     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16     where the sampler shall look for instrument editor plugins
17     (patch by Luis Garrido, slightly modified).
18 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21     note (in this implementation of the sampler its simply hard routed to
22     the 1st effect send of the sampler channel, no matter what the actual
23     effect type is)
24     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25     note (in this implementation of the sampler its simply hard routed to
26     the 2nd effect send of the sampler channel, no matter what the actual
27     effect type is)
28 schoenebeck 2124 - implemented support for internal LADSPA effects
29 schoenebeck 2140 - raised limit of program change queue from 100 to 512
30     (as suggested by Alex Stone)

160 schoenebeck 1599
161 schoenebeck 1639 * packaging changes:
162     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

207 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
208     be switched on by command line option "--stacktrace" (the automatic
209     stacktrace mechanism seems to be broken on most systems at the moment)
210 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
211     a pointer to the launched InstrumentEditor object
212 schoenebeck 1876 - added optional 3rd party user data parameter for following
213     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
214     InstrumentEditor::Launch(),

226 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
227     opposed to the LSCP specs
228 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
229     reflected the wrong value

233 persson 1748 jack_client_new
234 iliev 1829 - added (experimental) CoreAudio driver
235 persson 1888 - applied old fixes to the ASIO driver that were included in the
236     previous binary release but accidentally never committed to CVS
237     (fixes #117)
238 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
239     win64)
240 persson 1895 - VST: added support for sample rate and buffer size changes
241     - VST: close editor (Fantasia) when the VST is removed

250     AudioChannel::CopyTo() methods using GCC vector exensions
251     (if available)
252 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
253     exception when getting parameters from a disconnected device
254 schoenebeck 1599
255 persson 1651 * MIDI driver:
256     - added JACK MIDI driver
257 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

274 persson 1908 - work-around for missing fnmatch function on Windows to make
275     instrument database compilable
276 schoenebeck 1930 - added instrument database support on Windows
277     works with both standalone mode and VST plugin.
278     the instruments DB file is located in
279     %USERPROFILE%\.linuxsampler\instruments.db which allows different
280     databases for each windows user
281     if no DB is present it automatically creates the .linuxsampler subdir
282     and then creates an empty DB
283 persson 1943 - fixed recursive import, which was broken on Windows
284 iliev 1603
285 persson 1644 * Gigasampler format engine:
286     - fixed a memory leak that could happen when a channel was deleted
287     while notes were playing
288 persson 1646 - made it possible to load an instrument even if the audio thread
289     isn't running
290 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
291     enough for piano gigs with pedal noise samples
292 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
293     respective FX send MIDI controller was used
294 schoenebeck 1724 - added support for GM global device volume SysEx message
295 schoenebeck 1762 (can be selected at compile time to either apply globally to the
296     whole sampler [default] or only to the sampler channels that are
297     connected to the respective MIDI input port the SysEx message arrived
298     on)
299 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
300     sometimes wrongly killed in the same buffer, causing no sound to
301     be played
302 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
303     which is usally used to switch a part between chromatic sounds and
304     drumkit sounds (as opposed to their common default setting of MIDI
305     part 10 being a drumkit part and all other ones chromatic parts), in
306     LS however one can switch between the first 16 MIDI instrument maps
307     defined for the sampler
308 persson 1764 - made it possible to create multiple sample channels even if the
309     audio thread isn't running
310 persson 1844 - fixed crash when removing channel with active voices (#116)
311 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
312     un-cache the respective sample if it's really not used by any
313     sampler engine anymore
314     - re-cache samples in case they were changed by an instrument editor,
315     e.g. when a sample was added while playing (#82)
316 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
317     same time stamp as the voice's note-on event and occured both in the
318     same audio fragment cycle (fixes bug #112)
319 persson 1858 - added support for the "fine tune" and "pitch bend range"
320     instrument-level gig parameters
321     - fixed minor artifacts in pitch bend handling
322 schoenebeck 1860 - added support for GS Reset SysEx message
323 persson 1862 - allow gig files to use unlimited downward pitch shifting
324     - added a limit check for upward pitch shifting
325 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
326     note was silent
327 persson 1923 - fixed crash happening when a pitch bend event arrived at the
328     same time a new instrument was loading
329 persson 1644
330 schoenebeck 1687 * LSCP server:
331     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
332     react on MIDI data arriving on certain sampler channels (so far only
333     Note-On and Note-Off events are sent via this LSCP event)
334 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
335     react on MIDI data arriving on certain MIDI input devices (so far only
336     Note-On and Note-Off events are sent via this LSCP event)
337 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
338     SET DB_INSTRUMENT FILE_PATH
339 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
340     frontends to send MIDI messages to specific sampler channel
341     - added two additional fields to GET FILE INSTRUMENT INFO command -
342     KEY_BINDINGS and KEYSWITCH_BINDINGS
343 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
344     was incorrect
345 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
346 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
347     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
348     be triggered respectively
349     - added new LSCP command "SET STREAMS" to globally alter the maximum
350     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
351     which will be triggered respectively
352 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
353     a gigedit file dialog is opened)
354 iliev 1848 - close all connections when LSCPServer is deleted
355 iliev 1882 - hard close of all sockets on exit
356 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
357     driver

373 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
374 iliev 1847 - fixed crash when changing the audio output device of a sampler
375     channel with loaded instrument and start playing notes
376 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
377 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
378     PowerPC, which probably could cause crashes on that platform
379 persson 1889 - fixed a memory management error which could cause a crash when a
380     plugin was unloaded

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