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)

210 schoenebeck 1599
211 schoenebeck 1639 * packaging changes:
212     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

230 schoenebeck 1639
231 schoenebeck 1601 * general changes:
232     - bugfix: on some POSIX systems instrument editor plugins refused to
233     load as we used a non-portable Linux specific struct field
234     (fixes bug #70, patch by Ronald Baljeu)
235 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
236     plugin DLL on Windows systems failed
237 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
238     - optimized the SynchronizedConfig class so it doesn't wait
239     unnecessarily long after an update
240 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
241     events (e.g. to highlight the pressed keys on the virtual keyboard
242     of gigedit)

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

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

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

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

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

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

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

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

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

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

436    
437 schoenebeck 1560 Version 0.5.1 (6 December 2007)
438 schoenebeck 1454
439     * packaging changes:
440     - added autoconf checks for pthread library
441     - added autoconf check for pthread bug found on certain NPTL-enabled
442     glibc versions (see Gentoo bug report #194076)
443 senoner 1502 - added autoconf checks for MS Windows
444 schoenebeck 1454
445 persson 1455 * general changes:
446     - bugfix: the thread used by an editor plugin didn't die when the
447     editor closed
448 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
449     out all the space. operator--() did not apply size_mask after
450     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
451     order to avoid problems with the _NonVolatileReader functions.
452     - bugfix: Stream.h: added a missing divide by BytesPerSample in
453     GetWriteSpace(). Since this function is currently only used in
454     the stream's qsort() compare function, it didn't trigger any
455     bugs.
456     - Resampler.h, Synthesizer.h: cubic interpolation now works in
457     24bit mode too. Faster method to read 24bit words on little
458     endian machines (x86): replaced 3 byte reads + shifts with a 1
459     unaligned 32bit read and shift
460     - experimental support for MS Windows (MIDI input via MME, AUDIO
461     output via ASIO)
462     - made handling of SIGINT signal (Ctrl-C) a bit more robust
463 iliev 1541 - support for monitoring the total number of active disk streams
464     (new LSCP commands: GET TOTAL_STREAM_COUNT,
465     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
466 persson 1455
467 senoner 1500 * AUDIO driver:
468 persson 1534 - added Windows ASIO low latency audio driver
469 senoner 1500
470 senoner 1485 * MIDI driver:
471 schoenebeck 1495 - added MME Windows MIDI driver
472 senoner 1485
473 schoenebeck 1471 * LSCP server:
474     - added support for Windows style path / filenames, however with
475     forward slash path separators instead of backslash
476     (i.e. "C:/foo/bar.gig")
477 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
478     apostrophes as well
479 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
480     "LIST FILE INSTRUMENTS <file>" and
481     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
482     about an arbitrary instrument file on the system where the sampler is
483     running on
484 schoenebeck 1471
485 schoenebeck 1424 Version 0.5.0 (15 October 2007)
486 schoenebeck 947
487 schoenebeck 1065 * packaging changes:
488 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
489     API header files anymore
490 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
491     the Doxygen API documentation (explicitly listed in Doxyfile.in)
492 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
493     capable to execute our autoconf environment, thus no need anymore
494     to maintain the compile time configuration file (osx/version.h) for
495     OSX manually (patch by Toshi Nagata)
496 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
497     parameters
498 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
499     C++ API header files, all implementation internal global definitions
500     are now in global_private.h
501     - atomic.h is not exposed to the C++ API anymore
502     - no need to include config.h anymore for using LS's API header files
503     - fixed warnings in API doc generation
504 schoenebeck 1065
505 schoenebeck 947 * general changes:
506     - replaced the old, confusing MIDI program change mechanism by a
507     flexible MIDI instrument mapper which allows to map arbitrary
508 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
509 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
510     loaded on the respective channel when such MIDI program change
511     messages arrive, beside that, each entry allows to define a life-time
512     strategy for the instrument, so the user can define whether the
513     instrument should i.e. be permanently loaded (to be able to switch
514     quickly among sounds) or i.e. loaded just on demand when the
515     respective program change arrives (to safe RAM space), as well as a
516     global volume factor for each entry, so the user can adjust the volume
517     dynamic of his mapped instrument collection without having to modify
518 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
519     MIDI instrument maps and assign each sampler channel individually
520     a certain map, so that i.e. separation of normal instruments and
521     drumkits is possible
522 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
523     MIDI instrument maps, MIDI instruments, FX sends, global volume.
524 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
525     due to a constant size RingBuffer FIFO which is now replaced by a
526     dynamic (unlimited) size std::list FIFO
527 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
528     output channels for being processed by external effect processors
529     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
530     controllers
531 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
532 iliev 1130 - Implemented new, improved notification system
533 schoenebeck 1149 - fixed compilation errors regarding OSX
534     (patch by Toshi Nagata)
535 iliev 1161 - implemented instruments database
536 iliev 1345 - added support for escape sequences to the instruments database
537 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
538     within the sampler's process (by using instrument editor plugins),
539     you'll notice the new "Registered instrument editors:" message on
540 schoenebeck 1407 startup, added a new LSCP command:
541     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
542 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
543     given sampler channel, the plugin path can be overridden at compile
544     time with ./configure --enable-plugin-dir=/some/dir
545 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
546     in the sampler's process to safely edit instruments while playing
547     without a crash (hopefully) by either suspending single regions
548     wherever possible or if unavoidable whole engine(s)
549 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
550     policy and priority on thread level, set a minimum stack size for
551     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
552     threads simply inherited properties of starting thread instead of
553     setting their own policy and priority
554 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
555     main process did not wait for the stack trace process to finish
556     its output
557 persson 1248 - fixed some minor memory leaks
558 schoenebeck 1259 - reenabled assembly features support, at the moment only for
559     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
560 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
561     register, to avoid relocations in the text segment at runtime)
562 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
563 schoenebeck 947
564     * MIDI driver:
565     - dispatch bank select (MSB and LSB) messages
566    
567 schoenebeck 1049 * audio driver:
568     - the ALSA audio output driver parameters now reflect the correct
569     parameter value ranges for the respective selected sound card
570     (patch by Till Wimmer, a bit fixed and extended)
571    
572 persson 951 * Gigasampler format engine:
573     - if a filter is used and EG2 finishes before EG1, let the voice
574     die when EG2 has finished (this fixes a problem with clicks and
575     voice starvation for some gigs)
576 persson 1038 - playback is no longer disabled during instrument loading
577     - all notes playing on a channel that changes its instrument keep
578     playing with the old instrument until they get a note off
579     command
580 persson 1039 - EG fix: a release value of zero could cause noises or crash
581 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
582 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
583     above max sustain level, which means that there is a decay phase
584     even if sustain is 100%
585 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
586     noises or crashes
587 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
588 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
589     supplied to the configure script (fixes #46)
590 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
591     instead of a fix value
592 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
593     127 (solo mode) only kill voices if the respective mode really
594     changed
595 persson 951
596 schoenebeck 1244 * LSCP server:
597     - fixed compile time error for old Bison versions
598     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
599 schoenebeck 1245 - parser now supports extended ASCII character set
600     (up to ASCII code 255, i.e. includes now umlauts and accents)
601     - filename arguments in LSCP commands now allow to use escape
602     sequences, that is directly literal as one of: \', \", \\, \n, \r,
603     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
604     code value like \xf2) (fixes bug #24)
605 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
606     least one of their text-based parameters (i.e. name, description):
607     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
608     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
609     "SET DB_INSTRUMENT_DIRECTORY NAME",
610     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
611     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
612     "FIND DB_INSTRUMENT_DIRECTORIES"
613 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
614     occured, the unexpected character and the actually expected, possible
615     character(s), the latter only if less than 5 possibilities)
616 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
617     settings
618 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
619     of strings were treated as being one string containing commas
620     (fixes #57)
621 schoenebeck 1244
622 iliev 959 * Bug fixes:
623     - fixed crash occurring on certain LSCP scripts (Bug 39)
624 persson 1038 - another thread safety fix for lscp "load engine" and "set
625     channel audio output device"
626 iliev 1283 - fixed a crash which occurs when reassigning the same engine
627     on a sampler channel with connected MIDI device
628 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
629     device connected to a sampler channel to number less then or equal
630     to the index of the port to which the sampler channel is connected.
631 iliev 1296 - The previous bindings were not been disconnected when altering
632     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
633     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
634 iliev 1297 - The active stream/voice count statistic was incorrect.
635 iliev 1298 - notification events were not been sent for some sampler
636     channel changes
637 iliev 1305 - added default min and max values to restrict the number of allowed
638     audio output channels and MIDI input ports
639 iliev 1306 - the connection to the PCM interface is now closed when destroying
640     an audio output device
641 schoenebeck 1332 - files with slash in their path or filename could not be loaded
642 iliev 959
643 schoenebeck 1221 * test cases:
644     - updated and fixed (haven't been touched in a while)
645    
646 schoenebeck 937 Version 0.4.0 (24 November 2006)
647 persson 696
648 schoenebeck 697 * packaging changes:
649 capela 868 - changed deprecated copyright attribute to license; added ldconfig
650     to post-(un)install steps; added devel package for liblinuxsampler;
651     to linuxsampler.spec (RPM)
652 schoenebeck 697 - install necessary development header files for allowing 3rd party
653     applications to link against liblinuxsampler
654     - liblinuxsampler's API documentation can be generated with 'make docs'
655     (Doxygen required)
656 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
657     implementation (currently either an integer math solution or a
658     di-harmonic approximation), automatic detection can be overriden
659     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
660     configure script argument though (mandatory for cross-compilation)
661 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
662     provided some on his own (as CXXFLAGS)
663 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
664     messages
665 schoenebeck 852 - added compile time options to allow disabling the various audio and
666     MIDI drivers
667 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
668     (patch by Ebrahim Mayat)
669 schoenebeck 697
670 persson 696 * Gigasampler format engine:
671 schoenebeck 738 - extensive synthesis optimization
672     (reimplementation of EGs and LFO(s), removed synthesis parameter
673     prerendering and the synthesis parameter matrix in general, splitting
674     each audio fragment into subfragments now where each subfragment uses
675 persson 830 constant pitch and filter coefficients. The volume coefficient is
676     linearly interpolated inside a subfragment, unless
677     --disable-interpolate-volume is set.)
678 persson 696 - fine tuning of the EG modulation parameters
679 persson 729 - improved filter cutoff calculation by adding support for the
680     following gig parameters: Cutoff freq (used when no cutoff
681     controller is defined), Control invert, Minimum cutoff, Velocity
682 persson 791 curve and Velocity range. The keyboard tracking now scales
683     cutoff frequency instead of resonance.
684 persson 877 - added support for gig parameter Resonance.
685 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
686 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
687     which can be overridden with --enable-global-attenuation
688 persson 783 - EG fixes: made the length of "attack hold" stage more
689     accurate. Release stage can now start before attack stage
690 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
691     time now has a minimal value to prevent clicks.
692 persson 799 - fixed pitch changes larger than one octave
693 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
694     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
695     all modes can be altered via standard GM messages, that is CC5 for
696     altering portamento time, CC65 for enabling / disabling portamento
697     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
698 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
699     parameter) and crossfade
700 persson 831 - added support for the "attenuation controller threshold" gig
701     parameter
702 persson 832 - added smoothing of volume changes caused by control change
703     messages
704 persson 865 - sample loop parameters are now taken from the DimensionRegion
705     instead of the wave chunk
706     - fixed keyswitching for v3 gigs with a number of keyswitch splits
707     not equal to a power of two
708 persson 877 - reimplementation of the filter algorithm. The new filter is more
709     accurate and supports all gig filter types, including bandreject
710     and lowpass turbo.
711 persson 903 - real support for 24 bit samples - samples are not truncated to
712     16 bits anymore
713     - support for aftertouch (channel pressure, not polyphonic
714     aftertouch)
715 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
716     amplifying from 0)
717 persson 696
718 schoenebeck 711 * LSCP server:
719     - fixed application exit on broken pipe error (fixes bug #20)
720 iliev 793 - fixed the notification messages delay due to lack of
721     network activity (fixes bug #26)
722 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
723     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
724 schoenebeck 711
725 schoenebeck 838 * audio driver:
726     - added aRts audio output driver (by no means RT safe)
727    
728 schoenebeck 775 * MIDI driver:
729     - fixed legacy sysex code which caused dispatching of MIDI SysEx
730     messages several times instead of once
731 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
732     for events (i.e. for offline rendering based MIDI drivers)
733 persson 922 - added checks for bad MIDI data
734 schoenebeck 775
735 schoenebeck 900 * linuxsampler application:
736     - show available sampler engine types on startup
737    
738 schoenebeck 705 * general changes:
739     - support for muting sampler channels and solo mode of the same, two new
740     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
741     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
742     introduced for this, the behavior is the same like on a mixer console
743 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
744     --enable-process-muted-channels which can be used to enable the
745     processing of muted channels.
746 iliev 777 - support for sostenuto pedal
747 iliev 779 - support for monitoring the total number of active voices
748 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
749     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
750 persson 835 - fixed some memory management errors
751 persson 841 - fixed some concurrency problems that could lead to crashes when
752     LSCP commands were executed
753 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
754     sampler channel (fixes bug #36)
755 schoenebeck 705
756 schoenebeck 692 Version 0.3.3 (15 July 2005)
757 schoenebeck 686
758     * packaging changes:
759     - fixed compilation with gcc 4.0
760    
761 schoenebeck 687 * Gigasampler format engine:
762     - LFO preprocessing was performed even though the respective LFO was
763     disabled by the instrument patch (minor efficiency fix)
764 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
765     for volume ramp downs in the same fragment (needed for current voice
766     stealing implementation) then simply inform the user with a warning
767     about possible click sounds and reduce the volume ramp down
768     appropriately instead of cancelling the audio device connection
769 schoenebeck 687
770 schoenebeck 677 Version 0.3.2 (24 June 2005)
771 schoenebeck 609
772     * packaging changes:
773     - updated autotools build files to compile on OS X
774     (conditional compilation of CoreMIDI and MidiShare drivers)
775 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
776     './configure --disable-asm' (definitely not recommended)
777 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
778     - require automake (>= 1.5) for 'make -f Makefile.cvs'
779     (due to 'dist-bzip2' automake option)
780 schoenebeck 649
781     * Gigasampler format engine:
782     - support for the gig parameters for "release velocity response" curves
783     - fine tuning of the EGADSR envelope
784     - volume of release triggered samples now depends on note-on velocity,
785     note length and gig parameter "release trigger decay" instead of
786     note-off velocity.
787 schoenebeck 663 - revised voice stealing
788     (fixes crash and endless loop caused by voice stealing)
789 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
790 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
791     instead of when the respective voice is actually launched
792     (fixes undefined behavior if stolen voices belonged to a key group -
793     this case was followed by a "killed voice survived" error message)
794 schoenebeck 669 - fixed minor issue with null/silence samples
795     (those stole voices even though they don't need a voice at all which
796     resulted in "voice stealing didn't work out" messages)
797 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
798     instrument or audio output device change
799 schoenebeck 654
800 schoenebeck 620 * LSCP server:
801 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
802 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
803 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
804 schoenebeck 609
805 schoenebeck 668 * linuxsampler application:
806     - added command line parameters --lscp-addr and --lscp-port to override
807     default IP address and port of LSCP server
808    
809 schoenebeck 579 Version 0.3.1 (24 May 2005)
810    
811     * initial release
