1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4     - LV2 Persist + Files support (patch by David Robillard)
5    
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8    
9     * general changes:
10 iliev 2012 - Refactoring: moved the independent code from
11     the Gigasampler format engine to base classes
12 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
13     respective profiling code is currently broken
14 schoenebeck 2053 - Introduced support for optional environment variable
15     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory

17     (patch by Luis Garrido, slightly modified).
18 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21     note (in this implementation of the sampler its simply hard routed to
22     the 1st effect send of the sampler channel, no matter what the actual
23     effect type is)
24     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25     note (in this implementation of the sampler its simply hard routed to
26     the 2nd effect send of the sampler channel, no matter what the actual
27     effect type is)
28 schoenebeck 2124 - implemented support for internal LADSPA effects

94 persson 2045 - VST bugfix: If the host called resume() before and after
95     changing sample rate or block size, the number of channels was
96     incorrectly set to two. This caused silence in Cubase 5.

157 schoenebeck 1599
158 schoenebeck 1639 * packaging changes:
159     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

223 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
224     opposed to the LSCP specs
225 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
226     reflected the wrong value
227 persson 1644 - fixed a memory management bug in ASIO driver
228 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

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

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

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

371 iliev 1847 - fixed crash when changing the audio output device of a sampler
372     channel with loaded instrument and start playing notes
373 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
374 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

376 persson 1889 - fixed a memory management error which could cause a crash when a
377     plugin was unloaded
378 persson 1896 - bugfix: two private structs had the same name, which could cause

380 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
381     Windows
382 iliev 1761
383    
384 schoenebeck 1560 Version 0.5.1 (6 December 2007)
385 schoenebeck 1454
386     * packaging changes:
387     - added autoconf checks for pthread library
388     - added autoconf check for pthread bug found on certain NPTL-enabled
389     glibc versions (see Gentoo bug report #194076)
390 senoner 1502 - added autoconf checks for MS Windows
391 schoenebeck 1454
392 persson 1455 * general changes:
393     - bugfix: the thread used by an editor plugin didn't die when the
394     editor closed
395 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
396     out all the space. operator--() did not apply size_mask after
397     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
398     order to avoid problems with the _NonVolatileReader functions.
399     - bugfix: Stream.h: added a missing divide by BytesPerSample in
400     GetWriteSpace(). Since this function is currently only used in
401     the stream's qsort() compare function, it didn't trigger any
402     bugs.
403     - Resampler.h, Synthesizer.h: cubic interpolation now works in
404     24bit mode too. Faster method to read 24bit words on little
405     endian machines (x86): replaced 3 byte reads + shifts with a 1
406     unaligned 32bit read and shift
407     - experimental support for MS Windows (MIDI input via MME, AUDIO
408     output via ASIO)
409     - made handling of SIGINT signal (Ctrl-C) a bit more robust
410 iliev 1541 - support for monitoring the total number of active disk streams
411     (new LSCP commands: GET TOTAL_STREAM_COUNT,
412     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
413 persson 1455
414 senoner 1500 * AUDIO driver:
415 persson 1534 - added Windows ASIO low latency audio driver
416 senoner 1500
417 senoner 1485 * MIDI driver:
418 schoenebeck 1495 - added MME Windows MIDI driver
419 senoner 1485
420 schoenebeck 1471 * LSCP server:
421     - added support for Windows style path / filenames, however with
422     forward slash path separators instead of backslash
423     (i.e. "C:/foo/bar.gig")
424 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
425     apostrophes as well
426 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
427     "LIST FILE INSTRUMENTS <file>" and
428     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
429     about an arbitrary instrument file on the system where the sampler is
430     running on
431 schoenebeck 1471
432 schoenebeck 1424 Version 0.5.0 (15 October 2007)
433 schoenebeck 947
434 schoenebeck 1065 * packaging changes:
435 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
436     API header files anymore
437 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
438     the Doxygen API documentation (explicitly listed in Doxyfile.in)
439 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
440     capable to execute our autoconf environment, thus no need anymore
441     to maintain the compile time configuration file (osx/version.h) for
442     OSX manually (patch by Toshi Nagata)
443 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
444     parameters
445 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
446     C++ API header files, all implementation internal global definitions
447     are now in global_private.h
448     - atomic.h is not exposed to the C++ API anymore
449     - no need to include config.h anymore for using LS's API header files
450     - fixed warnings in API doc generation
451 schoenebeck 1065
452 schoenebeck 947 * general changes:
453     - replaced the old, confusing MIDI program change mechanism by a
454     flexible MIDI instrument mapper which allows to map arbitrary
455 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
456 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
457     loaded on the respective channel when such MIDI program change
458     messages arrive, beside that, each entry allows to define a life-time
459     strategy for the instrument, so the user can define whether the
460     instrument should i.e. be permanently loaded (to be able to switch
461     quickly among sounds) or i.e. loaded just on demand when the
462     respective program change arrives (to safe RAM space), as well as a
463     global volume factor for each entry, so the user can adjust the volume
464     dynamic of his mapped instrument collection without having to modify
465 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
466     MIDI instrument maps and assign each sampler channel individually
467     a certain map, so that i.e. separation of normal instruments and
468     drumkits is possible
469 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
470     MIDI instrument maps, MIDI instruments, FX sends, global volume.
471 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
472     due to a constant size RingBuffer FIFO which is now replaced by a
473     dynamic (unlimited) size std::list FIFO
474 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
475     output channels for being processed by external effect processors
476     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
477     controllers
478 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
479 iliev 1130 - Implemented new, improved notification system
480 schoenebeck 1149 - fixed compilation errors regarding OSX
481     (patch by Toshi Nagata)
482 iliev 1161 - implemented instruments database
483 iliev 1345 - added support for escape sequences to the instruments database
484 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
485     within the sampler's process (by using instrument editor plugins),
486     you'll notice the new "Registered instrument editors:" message on
487 schoenebeck 1407 startup, added a new LSCP command:
488     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
489 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
490     given sampler channel, the plugin path can be overridden at compile
491     time with ./configure --enable-plugin-dir=/some/dir
492 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
493     in the sampler's process to safely edit instruments while playing
494     without a crash (hopefully) by either suspending single regions
495     wherever possible or if unavoidable whole engine(s)
496 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
497     policy and priority on thread level, set a minimum stack size for
498     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
499     threads simply inherited properties of starting thread instead of
500     setting their own policy and priority
501 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
502     main process did not wait for the stack trace process to finish
503     its output
504 persson 1248 - fixed some minor memory leaks
505 schoenebeck 1259 - reenabled assembly features support, at the moment only for
506     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
507 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
508     register, to avoid relocations in the text segment at runtime)
509 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
510 schoenebeck 947
511     * MIDI driver:
512     - dispatch bank select (MSB and LSB) messages
513    
514 schoenebeck 1049 * audio driver:
515     - the ALSA audio output driver parameters now reflect the correct
516     parameter value ranges for the respective selected sound card
517     (patch by Till Wimmer, a bit fixed and extended)
518    
519 persson 951 * Gigasampler format engine:
520     - if a filter is used and EG2 finishes before EG1, let the voice
521     die when EG2 has finished (this fixes a problem with clicks and
522     voice starvation for some gigs)
523 persson 1038 - playback is no longer disabled during instrument loading
524     - all notes playing on a channel that changes its instrument keep
525     playing with the old instrument until they get a note off
526     command
527 persson 1039 - EG fix: a release value of zero could cause noises or crash
528 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
529 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
530     above max sustain level, which means that there is a decay phase
531     even if sustain is 100%
532 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
533     noises or crashes
534 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
535 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
536     supplied to the configure script (fixes #46)
537 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
538     instead of a fix value
539 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
540     127 (solo mode) only kill voices if the respective mode really
541     changed
542 persson 951
543 schoenebeck 1244 * LSCP server:
544     - fixed compile time error for old Bison versions
545     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
546 schoenebeck 1245 - parser now supports extended ASCII character set
547     (up to ASCII code 255, i.e. includes now umlauts and accents)
548     - filename arguments in LSCP commands now allow to use escape
549     sequences, that is directly literal as one of: \', \", \\, \n, \r,
550     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
551     code value like \xf2) (fixes bug #24)
552 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
553     least one of their text-based parameters (i.e. name, description):
554     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
555     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
556     "SET DB_INSTRUMENT_DIRECTORY NAME",
557     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
558     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
559     "FIND DB_INSTRUMENT_DIRECTORIES"
560 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
561     occured, the unexpected character and the actually expected, possible
562     character(s), the latter only if less than 5 possibilities)
563 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
564     settings
565 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
566     of strings were treated as being one string containing commas
567     (fixes #57)
568 schoenebeck 1244
569 iliev 959 * Bug fixes:
570     - fixed crash occurring on certain LSCP scripts (Bug 39)
571 persson 1038 - another thread safety fix for lscp "load engine" and "set
572     channel audio output device"
573 iliev 1283 - fixed a crash which occurs when reassigning the same engine
574     on a sampler channel with connected MIDI device
575 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
576     device connected to a sampler channel to number less then or equal
577     to the index of the port to which the sampler channel is connected.
578 iliev 1296 - The previous bindings were not been disconnected when altering
579     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
580     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
581 iliev 1297 - The active stream/voice count statistic was incorrect.
582 iliev 1298 - notification events were not been sent for some sampler
583     channel changes
584 iliev 1305 - added default min and max values to restrict the number of allowed
585     audio output channels and MIDI input ports
586 iliev 1306 - the connection to the PCM interface is now closed when destroying
587     an audio output device
588 schoenebeck 1332 - files with slash in their path or filename could not be loaded
589 iliev 959
590 schoenebeck 1221 * test cases:
591     - updated and fixed (haven't been touched in a while)
592    
593 schoenebeck 937 Version 0.4.0 (24 November 2006)
594 persson 696
595 schoenebeck 697 * packaging changes:
596 capela 868 - changed deprecated copyright attribute to license; added ldconfig
597     to post-(un)install steps; added devel package for liblinuxsampler;
598     to linuxsampler.spec (RPM)
599 schoenebeck 697 - install necessary development header files for allowing 3rd party
600     applications to link against liblinuxsampler
601     - liblinuxsampler's API documentation can be generated with 'make docs'
602     (Doxygen required)
603 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
604     implementation (currently either an integer math solution or a
605     di-harmonic approximation), automatic detection can be overriden
606     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
607     configure script argument though (mandatory for cross-compilation)
608 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
609     provided some on his own (as CXXFLAGS)
610 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
611     messages
612 schoenebeck 852 - added compile time options to allow disabling the various audio and
613     MIDI drivers
614 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
615     (patch by Ebrahim Mayat)
616 schoenebeck 697
617 persson 696 * Gigasampler format engine:
618 schoenebeck 738 - extensive synthesis optimization
619     (reimplementation of EGs and LFO(s), removed synthesis parameter
620     prerendering and the synthesis parameter matrix in general, splitting
621     each audio fragment into subfragments now where each subfragment uses
622 persson 830 constant pitch and filter coefficients. The volume coefficient is
623     linearly interpolated inside a subfragment, unless
624     --disable-interpolate-volume is set.)
625 persson 696 - fine tuning of the EG modulation parameters
626 persson 729 - improved filter cutoff calculation by adding support for the
627     following gig parameters: Cutoff freq (used when no cutoff
628     controller is defined), Control invert, Minimum cutoff, Velocity
629 persson 791 curve and Velocity range. The keyboard tracking now scales
630     cutoff frequency instead of resonance.
631 persson 877 - added support for gig parameter Resonance.
632 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
633 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
634     which can be overridden with --enable-global-attenuation
635 persson 783 - EG fixes: made the length of "attack hold" stage more
636     accurate. Release stage can now start before attack stage
637 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
638     time now has a minimal value to prevent clicks.
639 persson 799 - fixed pitch changes larger than one octave
640 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
641     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
642     all modes can be altered via standard GM messages, that is CC5 for
643     altering portamento time, CC65 for enabling / disabling portamento
644     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
645 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
646     parameter) and crossfade
647 persson 831 - added support for the "attenuation controller threshold" gig
648     parameter
649 persson 832 - added smoothing of volume changes caused by control change
650     messages
651 persson 865 - sample loop parameters are now taken from the DimensionRegion
652     instead of the wave chunk
653     - fixed keyswitching for v3 gigs with a number of keyswitch splits
654     not equal to a power of two
655 persson 877 - reimplementation of the filter algorithm. The new filter is more
656     accurate and supports all gig filter types, including bandreject
657     and lowpass turbo.
658 persson 903 - real support for 24 bit samples - samples are not truncated to
659     16 bits anymore
660     - support for aftertouch (channel pressure, not polyphonic
661     aftertouch)
662 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
663     amplifying from 0)
664 persson 696
665 schoenebeck 711 * LSCP server:
666     - fixed application exit on broken pipe error (fixes bug #20)
667 iliev 793 - fixed the notification messages delay due to lack of
668     network activity (fixes bug #26)
669 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
670     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
671 schoenebeck 711
672 schoenebeck 838 * audio driver:
673     - added aRts audio output driver (by no means RT safe)
674    
675 schoenebeck 775 * MIDI driver:
676     - fixed legacy sysex code which caused dispatching of MIDI SysEx
677     messages several times instead of once
678 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
679     for events (i.e. for offline rendering based MIDI drivers)
680 persson 922 - added checks for bad MIDI data
681 schoenebeck 775
682 schoenebeck 900 * linuxsampler application:
683     - show available sampler engine types on startup
684    
685 schoenebeck 705 * general changes:
686     - support for muting sampler channels and solo mode of the same, two new
687     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
688     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
689     introduced for this, the behavior is the same like on a mixer console
690 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
691     --enable-process-muted-channels which can be used to enable the
692     processing of muted channels.
693 iliev 777 - support for sostenuto pedal
694 iliev 779 - support for monitoring the total number of active voices
695 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
696     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
697 persson 835 - fixed some memory management errors
698 persson 841 - fixed some concurrency problems that could lead to crashes when
699     LSCP commands were executed
700 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
701     sampler channel (fixes bug #36)
702 schoenebeck 705
703 schoenebeck 692 Version 0.3.3 (15 July 2005)
704 schoenebeck 686
705     * packaging changes:
706     - fixed compilation with gcc 4.0
707    
708 schoenebeck 687 * Gigasampler format engine:
709     - LFO preprocessing was performed even though the respective LFO was
710     disabled by the instrument patch (minor efficiency fix)
711 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
712     for volume ramp downs in the same fragment (needed for current voice
713     stealing implementation) then simply inform the user with a warning
714     about possible click sounds and reduce the volume ramp down
715     appropriately instead of cancelling the audio device connection
716 schoenebeck 687
717 schoenebeck 677 Version 0.3.2 (24 June 2005)
718 schoenebeck 609
719     * packaging changes:
720     - updated autotools build files to compile on OS X
721     (conditional compilation of CoreMIDI and MidiShare drivers)
722 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
723     './configure --disable-asm' (definitely not recommended)
724 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
725     - require automake (>= 1.5) for 'make -f Makefile.cvs'
726     (due to 'dist-bzip2' automake option)
727 schoenebeck 649
728     * Gigasampler format engine:
729     - support for the gig parameters for "release velocity response" curves
730     - fine tuning of the EGADSR envelope
731     - volume of release triggered samples now depends on note-on velocity,
732     note length and gig parameter "release trigger decay" instead of
733     note-off velocity.
734 schoenebeck 663 - revised voice stealing
735     (fixes crash and endless loop caused by voice stealing)
736 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
737 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
738     instead of when the respective voice is actually launched
739     (fixes undefined behavior if stolen voices belonged to a key group -
740     this case was followed by a "killed voice survived" error message)
741 schoenebeck 669 - fixed minor issue with null/silence samples
742     (those stole voices even though they don't need a voice at all which
743     resulted in "voice stealing didn't work out" messages)
744 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
745     instrument or audio output device change
746 schoenebeck 654
747 schoenebeck 620 * LSCP server:
748 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
749 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
750 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
751 schoenebeck 609
752 schoenebeck 668 * linuxsampler application:
753     - added command line parameters --lscp-addr and --lscp-port to override
754     default IP address and port of LSCP server
755    
756 schoenebeck 579 Version 0.3.1 (24 May 2005)
757    
758     * initial release
