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 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X

19     configure
20 persson 2086
21     * general changes:
22 iliev 2012 - Refactoring: moved the independent code from
23     the Gigasampler format engine to base classes
24 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
25     respective profiling code is currently broken
26 schoenebeck 2053 - Introduced support for optional environment variable
27     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory

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

191 schoenebeck 1599
192 schoenebeck 1639 * packaging changes:

211 schoenebeck 1639
212 schoenebeck 1601 * general changes:
213     - bugfix: on some POSIX systems instrument editor plugins refused to

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

237 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
238 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
239     be switched on by command line option "--stacktrace" (the automatic
240     stacktrace mechanism seems to be broken on most systems at the moment)
241 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
242     a pointer to the launched InstrumentEditor object
243 schoenebeck 1876 - added optional 3rd party user data parameter for following
244     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
245     InstrumentEditor::Launch(),

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

254 schoenebeck 1599 * audio driver:
255     - removed the nonsense audio channel constraint (which was hard coded to
256     max. 100 audio channels) for most audio drivers
257 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
258     opposed to the LSCP specs
259 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
260     reflected the wrong value

264 persson 1748 jack_client_new
265 iliev 1829 - added (experimental) CoreAudio driver
266 persson 1888 - applied old fixes to the ASIO driver that were included in the
267     previous binary release but accidentally never committed to CVS
268     (fixes #117)
269 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
270     win64)
271 persson 1895 - VST: added support for sample rate and buffer size changes
272     - VST: close editor (Fantasia) when the VST is removed

281     AudioChannel::CopyTo() methods using GCC vector exensions
282     (if available)
283 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
284     exception when getting parameters from a disconnected device
285 schoenebeck 1599
286 persson 1651 * MIDI driver:
287     - added JACK MIDI driver
288 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
289     want to (mis)use it for some purpose ("fixed" in all current MIDI
290     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
291 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
292 persson 1887 CoreMidi or AU

300     to the instruments database
301 iliev 1727 - added support for handling lost files in the instruments database
302 iliev 1781 - Implemented option for adding instruments in separate directories
303     in the instruments database
304     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
305 persson 1908 - work-around for missing fnmatch function on Windows to make
306     instrument database compilable
307 schoenebeck 1930 - added instrument database support on Windows
308     works with both standalone mode and VST plugin.
309     the instruments DB file is located in
310     %USERPROFILE%\.linuxsampler\instruments.db which allows different
311     databases for each windows user
312     if no DB is present it automatically creates the .linuxsampler subdir
313     and then creates an empty DB
314 persson 1943 - fixed recursive import, which was broken on Windows
315 iliev 1603
316 persson 1644 * Gigasampler format engine:
317     - fixed a memory leak that could happen when a channel was deleted
318     while notes were playing
319 persson 1646 - made it possible to load an instrument even if the audio thread
320     isn't running
321 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
322     enough for piano gigs with pedal noise samples
323 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
324     respective FX send MIDI controller was used
325 schoenebeck 1724 - added support for GM global device volume SysEx message
326 schoenebeck 1762 (can be selected at compile time to either apply globally to the
327     whole sampler [default] or only to the sampler channels that are
328     connected to the respective MIDI input port the SysEx message arrived
329     on)
330 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
331     sometimes wrongly killed in the same buffer, causing no sound to
332     be played
333 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
334     which is usally used to switch a part between chromatic sounds and
335     drumkit sounds (as opposed to their common default setting of MIDI
336     part 10 being a drumkit part and all other ones chromatic parts), in
337     LS however one can switch between the first 16 MIDI instrument maps
338     defined for the sampler
339 persson 1764 - made it possible to create multiple sample channels even if the
340     audio thread isn't running
341 persson 1844 - fixed crash when removing channel with active voices (#116)
342 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
343     un-cache the respective sample if it's really not used by any
344     sampler engine anymore
345     - re-cache samples in case they were changed by an instrument editor,
346     e.g. when a sample was added while playing (#82)
347 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
348     same time stamp as the voice's note-on event and occured both in the
349     same audio fragment cycle (fixes bug #112)
350 persson 1858 - added support for the "fine tune" and "pitch bend range"
351     instrument-level gig parameters
352     - fixed minor artifacts in pitch bend handling
353 schoenebeck 1860 - added support for GS Reset SysEx message
354 persson 1862 - allow gig files to use unlimited downward pitch shifting
355     - added a limit check for upward pitch shifting
356 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
357     note was silent
358 persson 1923 - fixed crash happening when a pitch bend event arrived at the
359     same time a new instrument was loading
360 persson 1644
361 schoenebeck 1687 * LSCP server:
362     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
363     react on MIDI data arriving on certain sampler channels (so far only
364     Note-On and Note-Off events are sent via this LSCP event)
365 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
366     react on MIDI data arriving on certain MIDI input devices (so far only
367     Note-On and Note-Off events are sent via this LSCP event)
368 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
369     SET DB_INSTRUMENT FILE_PATH
370 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
371     frontends to send MIDI messages to specific sampler channel
372     - added two additional fields to GET FILE INSTRUMENT INFO command -
373     KEY_BINDINGS and KEYSWITCH_BINDINGS
374 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
375     was incorrect
376 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
377 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
378     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
379     be triggered respectively
380     - added new LSCP command "SET STREAMS" to globally alter the maximum
381     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
382     which will be triggered respectively
383 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
384     a gigedit file dialog is opened)
385 iliev 1848 - close all connections when LSCPServer is deleted
386 iliev 1882 - hard close of all sockets on exit
387 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
388     driver
389 schoenebeck 1687
390 iliev 1761 * Bug fixes:
391     - fixed a crash which occurs when removing a sampler channel waiting
392     to start instrument loading after another channel
393 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
394     instrument loading in progress (bug #113)
395 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
396     instrument with PERSISTENT load mode
397 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
398     - fixed memory leaks when issuing the following LSCP commands:
399     GET AUDIO_OUTPUT_DRIVER INFO
400     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
401     GET MIDI_INPUT_DRIVER INFO
402     GET MIDI_INPUT_DRIVER_PARAMETER INFO
403     - fixed possible compilation error when sqlite is not present
404 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
405 iliev 1847 - fixed crash when changing the audio output device of a sampler
406     channel with loaded instrument and start playing notes
407 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
408 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
409     PowerPC, which probably could cause crashes on that platform
410 persson 1889 - fixed a memory management error which could cause a crash when a
411     plugin was unloaded
412 persson 1896 - bugfix: two private structs had the same name, which could cause
413     problems if the linker chose the wrong constructor
414 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
415     Windows

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