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 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14     - another "make dist" fix, for LV2 plugin
15     - made --enable-pthread-testcancel default on Mac OS X
16 persson 2086
17     * general changes:
18 iliev 2012 - Refactoring: moved the independent code from
19     the Gigasampler format engine to base classes
20 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
21     respective profiling code is currently broken
22 schoenebeck 2053 - Introduced support for optional environment variable
23     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory

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

173 schoenebeck 1599
174 schoenebeck 1639 * packaging changes:
175     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

193 schoenebeck 1639
194 schoenebeck 1601 * general changes:
195     - bugfix: on some POSIX systems instrument editor plugins refused to
196     load as we used a non-portable Linux specific struct field
197     (fixes bug #70, patch by Ronald Baljeu)
198 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
199     plugin DLL on Windows systems failed

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

236 schoenebeck 1599 * audio driver:
237     - removed the nonsense audio channel constraint (which was hard coded to
238     max. 100 audio channels) for most audio drivers
239 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
240     opposed to the LSCP specs
241 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
242     reflected the wrong value
243 persson 1644 - fixed a memory management bug in ASIO driver
244 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

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

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

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

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

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