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 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
16 persson 2197 - minor Makefile fix for building lscpparser when build and source
17     directories are separate
18 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

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

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

214     after MIDI/audio device creation failure
215 iliev 2012

217 schoenebeck 1599
218 schoenebeck 1639 * packaging changes:
219     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

237 schoenebeck 1639
238 schoenebeck 1601 * general changes:
239     - bugfix: on some POSIX systems instrument editor plugins refused to
240     load as we used a non-portable Linux specific struct field
241     (fixes bug #70, patch by Ronald Baljeu)
242 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
243     plugin DLL on Windows systems failed
244 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
245     - optimized the SynchronizedConfig class so it doesn't wait
246     unnecessarily long after an update
247 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off

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

264 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
265     be switched on by command line option "--stacktrace" (the automatic
266     stacktrace mechanism seems to be broken on most systems at the moment)
267 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
268     a pointer to the launched InstrumentEditor object
269 schoenebeck 1876 - added optional 3rd party user data parameter for following
270     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
271     InstrumentEditor::Launch(),
272     InstrumentManager::LaunchInstrumentEditor()
273 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
274     model more strictly
275 persson 1895 - fixes for using large audio device buffers
276 persson 1951 - Windows: add the installation directory to the DLL search path

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

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

307     AudioChannel::CopyTo() methods using GCC vector exensions
308     (if available)
309 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
310     exception when getting parameters from a disconnected device
311 schoenebeck 1599
312 persson 1651 * MIDI driver:
313     - added JACK MIDI driver
314 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
315     want to (mis)use it for some purpose ("fixed" in all current MIDI
316     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
317 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
318 persson 1887 CoreMidi or AU
319 persson 1889 - fixed mingw-w64 compilation error in MME driver
320 persson 1924 - made program change handling in MIDI thread real-time safe by

326     to the instruments database
327 iliev 1727 - added support for handling lost files in the instruments database
328 iliev 1781 - Implemented option for adding instruments in separate directories
329     in the instruments database
330     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
331 persson 1908 - work-around for missing fnmatch function on Windows to make
332     instrument database compilable
333 schoenebeck 1930 - added instrument database support on Windows
334     works with both standalone mode and VST plugin.
335     the instruments DB file is located in
336     %USERPROFILE%\.linuxsampler\instruments.db which allows different
337     databases for each windows user
338     if no DB is present it automatically creates the .linuxsampler subdir
339     and then creates an empty DB
340 persson 1943 - fixed recursive import, which was broken on Windows
341 iliev 1603
342 persson 1644 * Gigasampler format engine:
343     - fixed a memory leak that could happen when a channel was deleted
344     while notes were playing
345 persson 1646 - made it possible to load an instrument even if the audio thread
346     isn't running
347 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
348     enough for piano gigs with pedal noise samples
349 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
350     respective FX send MIDI controller was used
351 schoenebeck 1724 - added support for GM global device volume SysEx message
352 schoenebeck 1762 (can be selected at compile time to either apply globally to the
353     whole sampler [default] or only to the sampler channels that are
354     connected to the respective MIDI input port the SysEx message arrived
355     on)
356 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
357     sometimes wrongly killed in the same buffer, causing no sound to
358     be played
359 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
360     which is usally used to switch a part between chromatic sounds and
361     drumkit sounds (as opposed to their common default setting of MIDI
362     part 10 being a drumkit part and all other ones chromatic parts), in
363     LS however one can switch between the first 16 MIDI instrument maps
364     defined for the sampler
365 persson 1764 - made it possible to create multiple sample channels even if the
366     audio thread isn't running
367 persson 1844 - fixed crash when removing channel with active voices (#116)
368 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
369     un-cache the respective sample if it's really not used by any
370     sampler engine anymore
371     - re-cache samples in case they were changed by an instrument editor,
372     e.g. when a sample was added while playing (#82)
373 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
374     same time stamp as the voice's note-on event and occured both in the
375     same audio fragment cycle (fixes bug #112)
376 persson 1858 - added support for the "fine tune" and "pitch bend range"

384 persson 1923 - fixed crash happening when a pitch bend event arrived at the
385     same time a new instrument was loading
386 persson 1644
387 schoenebeck 1687 * LSCP server:
388     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
389     react on MIDI data arriving on certain sampler channels (so far only
390     Note-On and Note-Off events are sent via this LSCP event)
391 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
392     react on MIDI data arriving on certain MIDI input devices (so far only
393     Note-On and Note-Off events are sent via this LSCP event)
394 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
395     SET DB_INSTRUMENT FILE_PATH

402 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
403 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
404     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
405     be triggered respectively
406     - added new LSCP command "SET STREAMS" to globally alter the maximum
407     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
408     which will be triggered respectively
409 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
410     a gigedit file dialog is opened)
411 iliev 1848 - close all connections when LSCPServer is deleted
412 iliev 1882 - hard close of all sockets on exit
413 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
414     driver
415 schoenebeck 1687
416 iliev 1761 * Bug fixes:
417     - fixed a crash which occurs when removing a sampler channel waiting
418     to start instrument loading after another channel
419 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
420     instrument loading in progress (bug #113)
421 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
422     instrument with PERSISTENT load mode

430 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
431 iliev 1847 - fixed crash when changing the audio output device of a sampler
432     channel with loaded instrument and start playing notes
433 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
434 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
435     PowerPC, which probably could cause crashes on that platform
436 persson 1889 - fixed a memory management error which could cause a crash when a
437     plugin was unloaded
438 persson 1896 - bugfix: two private structs had the same name, which could cause
439     problems if the linker chose the wrong constructor
440 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
441     Windows

443    
444 schoenebeck 1560 Version 0.5.1 (6 December 2007)
445 schoenebeck 1454
446     * packaging changes:
447     - added autoconf checks for pthread library
448     - added autoconf check for pthread bug found on certain NPTL-enabled
449     glibc versions (see Gentoo bug report #194076)
450 senoner 1502 - added autoconf checks for MS Windows
451 schoenebeck 1454
452 persson 1455 * general changes:
453     - bugfix: the thread used by an editor plugin didn't die when the
454     editor closed
455 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
456     out all the space. operator--() did not apply size_mask after
457     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
458     order to avoid problems with the _NonVolatileReader functions.
459     - bugfix: Stream.h: added a missing divide by BytesPerSample in
460     GetWriteSpace(). Since this function is currently only used in
461     the stream's qsort() compare function, it didn't trigger any
462     bugs.
463     - Resampler.h, Synthesizer.h: cubic interpolation now works in
464     24bit mode too. Faster method to read 24bit words on little
465     endian machines (x86): replaced 3 byte reads + shifts with a 1
466     unaligned 32bit read and shift
467     - experimental support for MS Windows (MIDI input via MME, AUDIO
468     output via ASIO)
469     - made handling of SIGINT signal (Ctrl-C) a bit more robust
470 iliev 1541 - support for monitoring the total number of active disk streams
471     (new LSCP commands: GET TOTAL_STREAM_COUNT,
472     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
473 persson 1455
474 senoner 1500 * AUDIO driver:
475 persson 1534 - added Windows ASIO low latency audio driver
476 senoner 1500
477 senoner 1485 * MIDI driver:
478 schoenebeck 1495 - added MME Windows MIDI driver
479 senoner 1485
480 schoenebeck 1471 * LSCP server:
481     - added support for Windows style path / filenames, however with
482     forward slash path separators instead of backslash
483     (i.e. "C:/foo/bar.gig")
484 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
485     apostrophes as well
486 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
487     "LIST FILE INSTRUMENTS <file>" and
488     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
489     about an arbitrary instrument file on the system where the sampler is
490     running on
491 schoenebeck 1471
492 schoenebeck 1424 Version 0.5.0 (15 October 2007)
493 schoenebeck 947
494 schoenebeck 1065 * packaging changes:
495 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
496     API header files anymore
497 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
498     the Doxygen API documentation (explicitly listed in Doxyfile.in)
499 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
500     capable to execute our autoconf environment, thus no need anymore
501     to maintain the compile time configuration file (osx/version.h) for
502     OSX manually (patch by Toshi Nagata)
503 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
504     parameters
505 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
506     C++ API header files, all implementation internal global definitions
507     are now in global_private.h
508     - atomic.h is not exposed to the C++ API anymore
509     - no need to include config.h anymore for using LS's API header files
510     - fixed warnings in API doc generation
511 schoenebeck 1065
512 schoenebeck 947 * general changes:
513     - replaced the old, confusing MIDI program change mechanism by a
514     flexible MIDI instrument mapper which allows to map arbitrary
515 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
516 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
517     loaded on the respective channel when such MIDI program change
518     messages arrive, beside that, each entry allows to define a life-time
519     strategy for the instrument, so the user can define whether the
520     instrument should i.e. be permanently loaded (to be able to switch
521     quickly among sounds) or i.e. loaded just on demand when the
522     respective program change arrives (to safe RAM space), as well as a
523     global volume factor for each entry, so the user can adjust the volume
524     dynamic of his mapped instrument collection without having to modify
525 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
526     MIDI instrument maps and assign each sampler channel individually
527     a certain map, so that i.e. separation of normal instruments and
528     drumkits is possible
529 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
530     MIDI instrument maps, MIDI instruments, FX sends, global volume.
531 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
532     due to a constant size RingBuffer FIFO which is now replaced by a
533     dynamic (unlimited) size std::list FIFO
534 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
535     output channels for being processed by external effect processors
536     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
537     controllers
538 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
539 iliev 1130 - Implemented new, improved notification system
540 schoenebeck 1149 - fixed compilation errors regarding OSX
541     (patch by Toshi Nagata)
542 iliev 1161 - implemented instruments database
543 iliev 1345 - added support for escape sequences to the instruments database
544 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
545     within the sampler's process (by using instrument editor plugins),
546     you'll notice the new "Registered instrument editors:" message on
547 schoenebeck 1407 startup, added a new LSCP command:
548     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
549 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
550     given sampler channel, the plugin path can be overridden at compile
551     time with ./configure --enable-plugin-dir=/some/dir
552 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
553     in the sampler's process to safely edit instruments while playing
554     without a crash (hopefully) by either suspending single regions
555     wherever possible or if unavoidable whole engine(s)
556 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
557     policy and priority on thread level, set a minimum stack size for
558     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
559     threads simply inherited properties of starting thread instead of
560     setting their own policy and priority
561 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
562     main process did not wait for the stack trace process to finish
563     its output
564 persson 1248 - fixed some minor memory leaks
565 schoenebeck 1259 - reenabled assembly features support, at the moment only for
566     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
567 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
568     register, to avoid relocations in the text segment at runtime)
569 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
570 schoenebeck 947
571     * MIDI driver:
572     - dispatch bank select (MSB and LSB) messages
573    
574 schoenebeck 1049 * audio driver:
575     - the ALSA audio output driver parameters now reflect the correct
576     parameter value ranges for the respective selected sound card
577     (patch by Till Wimmer, a bit fixed and extended)
578    
579 persson 951 * Gigasampler format engine:
580     - if a filter is used and EG2 finishes before EG1, let the voice
581     die when EG2 has finished (this fixes a problem with clicks and
582     voice starvation for some gigs)
583 persson 1038 - playback is no longer disabled during instrument loading
584     - all notes playing on a channel that changes its instrument keep
585     playing with the old instrument until they get a note off
586     command
587 persson 1039 - EG fix: a release value of zero could cause noises or crash
588 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
589 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
590     above max sustain level, which means that there is a decay phase
591     even if sustain is 100%
592 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
593     noises or crashes
594 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
595 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
596     supplied to the configure script (fixes #46)
597 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
598     instead of a fix value
599 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
600     127 (solo mode) only kill voices if the respective mode really
601     changed
602 persson 951
603 schoenebeck 1244 * LSCP server:
604     - fixed compile time error for old Bison versions
605     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
606 schoenebeck 1245 - parser now supports extended ASCII character set
607     (up to ASCII code 255, i.e. includes now umlauts and accents)
608     - filename arguments in LSCP commands now allow to use escape
609     sequences, that is directly literal as one of: \', \", \\, \n, \r,
610     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
611     code value like \xf2) (fixes bug #24)
612 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
613     least one of their text-based parameters (i.e. name, description):
614     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
615     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
616     "SET DB_INSTRUMENT_DIRECTORY NAME",
617     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
618     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
619     "FIND DB_INSTRUMENT_DIRECTORIES"
620 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
621     occured, the unexpected character and the actually expected, possible
622     character(s), the latter only if less than 5 possibilities)
623 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
624     settings
625 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
626     of strings were treated as being one string containing commas
627     (fixes #57)
628 schoenebeck 1244
629 iliev 959 * Bug fixes:
630     - fixed crash occurring on certain LSCP scripts (Bug 39)
631 persson 1038 - another thread safety fix for lscp "load engine" and "set
632     channel audio output device"
633 iliev 1283 - fixed a crash which occurs when reassigning the same engine
634     on a sampler channel with connected MIDI device
635 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
636     device connected to a sampler channel to number less then or equal
637     to the index of the port to which the sampler channel is connected.
638 iliev 1296 - The previous bindings were not been disconnected when altering
639     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
640     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
641 iliev 1297 - The active stream/voice count statistic was incorrect.
642 iliev 1298 - notification events were not been sent for some sampler
643     channel changes
644 iliev 1305 - added default min and max values to restrict the number of allowed
645     audio output channels and MIDI input ports
646 iliev 1306 - the connection to the PCM interface is now closed when destroying
647     an audio output device
648 schoenebeck 1332 - files with slash in their path or filename could not be loaded
649 iliev 959
650 schoenebeck 1221 * test cases:
651     - updated and fixed (haven't been touched in a while)
652    
653 schoenebeck 937 Version 0.4.0 (24 November 2006)
654 persson 696
655 schoenebeck 697 * packaging changes:
656 capela 868 - changed deprecated copyright attribute to license; added ldconfig
657     to post-(un)install steps; added devel package for liblinuxsampler;
658     to linuxsampler.spec (RPM)
659 schoenebeck 697 - install necessary development header files for allowing 3rd party
660     applications to link against liblinuxsampler
661     - liblinuxsampler's API documentation can be generated with 'make docs'
662     (Doxygen required)
663 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
664     implementation (currently either an integer math solution or a
665     di-harmonic approximation), automatic detection can be overriden
666     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
667     configure script argument though (mandatory for cross-compilation)
668 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
669     provided some on his own (as CXXFLAGS)
670 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
671     messages
672 schoenebeck 852 - added compile time options to allow disabling the various audio and
673     MIDI drivers
674 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
675     (patch by Ebrahim Mayat)
676 schoenebeck 697
677 persson 696 * Gigasampler format engine:
678 schoenebeck 738 - extensive synthesis optimization
679     (reimplementation of EGs and LFO(s), removed synthesis parameter
680     prerendering and the synthesis parameter matrix in general, splitting
681     each audio fragment into subfragments now where each subfragment uses
682 persson 830 constant pitch and filter coefficients. The volume coefficient is
683     linearly interpolated inside a subfragment, unless
684     --disable-interpolate-volume is set.)
685 persson 696 - fine tuning of the EG modulation parameters
686 persson 729 - improved filter cutoff calculation by adding support for the
687     following gig parameters: Cutoff freq (used when no cutoff
688     controller is defined), Control invert, Minimum cutoff, Velocity
689 persson 791 curve and Velocity range. The keyboard tracking now scales
690     cutoff frequency instead of resonance.
691 persson 877 - added support for gig parameter Resonance.
692 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
693 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
694     which can be overridden with --enable-global-attenuation
695 persson 783 - EG fixes: made the length of "attack hold" stage more
696     accurate. Release stage can now start before attack stage
697 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
698     time now has a minimal value to prevent clicks.
699 persson 799 - fixed pitch changes larger than one octave
700 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
701     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
702     all modes can be altered via standard GM messages, that is CC5 for
703     altering portamento time, CC65 for enabling / disabling portamento
704     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
705 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
706     parameter) and crossfade
707 persson 831 - added support for the "attenuation controller threshold" gig
708     parameter
709 persson 832 - added smoothing of volume changes caused by control change
710     messages
711 persson 865 - sample loop parameters are now taken from the DimensionRegion
712     instead of the wave chunk
713     - fixed keyswitching for v3 gigs with a number of keyswitch splits
714     not equal to a power of two
715 persson 877 - reimplementation of the filter algorithm. The new filter is more
716     accurate and supports all gig filter types, including bandreject
717     and lowpass turbo.
718 persson 903 - real support for 24 bit samples - samples are not truncated to
719     16 bits anymore
720     - support for aftertouch (channel pressure, not polyphonic
721     aftertouch)
722 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
723     amplifying from 0)
724 persson 696
725 schoenebeck 711 * LSCP server:
726     - fixed application exit on broken pipe error (fixes bug #20)
727 iliev 793 - fixed the notification messages delay due to lack of
728     network activity (fixes bug #26)
729 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
730     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
731 schoenebeck 711
732 schoenebeck 838 * audio driver:
733     - added aRts audio output driver (by no means RT safe)
734    
735 schoenebeck 775 * MIDI driver:
736     - fixed legacy sysex code which caused dispatching of MIDI SysEx
737     messages several times instead of once
738 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
739     for events (i.e. for offline rendering based MIDI drivers)
740 persson 922 - added checks for bad MIDI data
741 schoenebeck 775
742 schoenebeck 900 * linuxsampler application:
743     - show available sampler engine types on startup
744    
745 schoenebeck 705 * general changes:
746     - support for muting sampler channels and solo mode of the same, two new
747     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
748     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
749     introduced for this, the behavior is the same like on a mixer console
750 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
751     --enable-process-muted-channels which can be used to enable the
752     processing of muted channels.
753 iliev 777 - support for sostenuto pedal
754 iliev 779 - support for monitoring the total number of active voices
755 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
756     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
757 persson 835 - fixed some memory management errors
758 persson 841 - fixed some concurrency problems that could lead to crashes when
759     LSCP commands were executed
760 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
761     sampler channel (fixes bug #36)
762 schoenebeck 705
763 schoenebeck 692 Version 0.3.3 (15 July 2005)
764 schoenebeck 686
765     * packaging changes:
766     - fixed compilation with gcc 4.0
767    
768 schoenebeck 687 * Gigasampler format engine:
769     - LFO preprocessing was performed even though the respective LFO was
770     disabled by the instrument patch (minor efficiency fix)
771 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
772     for volume ramp downs in the same fragment (needed for current voice
773     stealing implementation) then simply inform the user with a warning
774     about possible click sounds and reduce the volume ramp down
775     appropriately instead of cancelling the audio device connection
776 schoenebeck 687
777 schoenebeck 677 Version 0.3.2 (24 June 2005)
778 schoenebeck 609
779     * packaging changes:
780     - updated autotools build files to compile on OS X
781     (conditional compilation of CoreMIDI and MidiShare drivers)
782 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
783     './configure --disable-asm' (definitely not recommended)
784 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
785     - require automake (>= 1.5) for 'make -f Makefile.cvs'
786     (due to 'dist-bzip2' automake option)
787 schoenebeck 649
788     * Gigasampler format engine:
789     - support for the gig parameters for "release velocity response" curves
790     - fine tuning of the EGADSR envelope
791     - volume of release triggered samples now depends on note-on velocity,
792     note length and gig parameter "release trigger decay" instead of
793     note-off velocity.
794 schoenebeck 663 - revised voice stealing
795     (fixes crash and endless loop caused by voice stealing)
796 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
797 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
798     instead of when the respective voice is actually launched
799     (fixes undefined behavior if stolen voices belonged to a key group -
800     this case was followed by a "killed voice survived" error message)
801 schoenebeck 669 - fixed minor issue with null/silence samples
802     (those stole voices even though they don't need a voice at all which
803     resulted in "voice stealing didn't work out" messages)
804 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
805     instrument or audio output device change
806 schoenebeck 654
807 schoenebeck 620 * LSCP server:
808 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
809 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
810 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
811 schoenebeck 609
812 schoenebeck 668 * linuxsampler application:
813     - added command line parameters --lscp-addr and --lscp-port to override
814     default IP address and port of LSCP server
815    
816 schoenebeck 579 Version 0.3.1 (24 May 2005)
817    
818     * initial release
