2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5    
6     * general changes:
7 iliev 2012 - Refactoring: moved the independent code from
8     the Gigasampler format engine to base classes
9 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
10     respective profiling code is currently broken
11 schoenebeck 2053 - Introduced support for optional environment variable
12     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13     where the sampler shall look for instrument editor plugins

15 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18     note (in this implementation of the sampler its simply hard routed to
19     the 1st effect send of the sampler channel, no matter what the actual
20     effect type is)
21     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22     note (in this implementation of the sampler its simply hard routed to
23     the 2nd effect send of the sampler channel, no matter what the actual
24     effect type is)

124 schoenebeck 1599
125 schoenebeck 1639 * packaging changes:
126     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
127     causing e.g. the libgig test to fail when

144 schoenebeck 1639
145 schoenebeck 1601 * general changes:
146     - bugfix: on some POSIX systems instrument editor plugins refused to

171 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
172     be switched on by command line option "--stacktrace" (the automatic
173     stacktrace mechanism seems to be broken on most systems at the moment)
174 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
175     a pointer to the launched InstrumentEditor object
176 schoenebeck 1876 - added optional 3rd party user data parameter for following
177     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
178     InstrumentEditor::Launch(),

187 schoenebeck 1599 * audio driver:
188     - removed the nonsense audio channel constraint (which was hard coded to
189     max. 100 audio channels) for most audio drivers
190 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
191     opposed to the LSCP specs
192 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
193     reflected the wrong value

197 persson 1748 jack_client_new
198 iliev 1829 - added (experimental) CoreAudio driver
199 persson 1888 - applied old fixes to the ASIO driver that were included in the
200     previous binary release but accidentally never committed to CVS
201     (fixes #117)
202 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
203     win64)
204 persson 1895 - VST: added support for sample rate and buffer size changes
205     - VST: close editor (Fantasia) when the VST is removed

214     AudioChannel::CopyTo() methods using GCC vector exensions
215     (if available)
216 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
217     exception when getting parameters from a disconnected device
218 schoenebeck 1599
219 persson 1651 * MIDI driver:
220     - added JACK MIDI driver
221 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
222     want to (mis)use it for some purpose ("fixed" in all current MIDI
223     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
224 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
225 persson 1887 CoreMidi or AU
226 persson 1889 - fixed mingw-w64 compilation error in MME driver
227 persson 1924 - made program change handling in MIDI thread real-time safe by
228     moving the logic to a non-RT thread

235 iliev 1781 - Implemented option for adding instruments in separate directories
236     in the instruments database
237     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
238 persson 1908 - work-around for missing fnmatch function on Windows to make
239     instrument database compilable
240 schoenebeck 1930 - added instrument database support on Windows
241     works with both standalone mode and VST plugin.
242     the instruments DB file is located in
243     %USERPROFILE%\.linuxsampler\instruments.db which allows different
244     databases for each windows user
245     if no DB is present it automatically creates the .linuxsampler subdir
246     and then creates an empty DB
247 persson 1943 - fixed recursive import, which was broken on Windows
248 iliev 1603
249 persson 1644 * Gigasampler format engine:
250     - fixed a memory leak that could happen when a channel was deleted
251     while notes were playing
252 persson 1646 - made it possible to load an instrument even if the audio thread
253     isn't running
254 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
255     enough for piano gigs with pedal noise samples
256 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
257     respective FX send MIDI controller was used
258 schoenebeck 1724 - added support for GM global device volume SysEx message
259 schoenebeck 1762 (can be selected at compile time to either apply globally to the
260     whole sampler [default] or only to the sampler channels that are
261     connected to the respective MIDI input port the SysEx message arrived
262     on)
263 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
264     sometimes wrongly killed in the same buffer, causing no sound to
265     be played
266 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
267     which is usally used to switch a part between chromatic sounds and
268     drumkit sounds (as opposed to their common default setting of MIDI
269     part 10 being a drumkit part and all other ones chromatic parts), in
270     LS however one can switch between the first 16 MIDI instrument maps
271     defined for the sampler
272 persson 1764 - made it possible to create multiple sample channels even if the
273     audio thread isn't running
274 persson 1844 - fixed crash when removing channel with active voices (#116)
275 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
276     un-cache the respective sample if it's really not used by any
277     sampler engine anymore
278     - re-cache samples in case they were changed by an instrument editor,
279     e.g. when a sample was added while playing (#82)
280 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
281     same time stamp as the voice's note-on event and occured both in the
282     same audio fragment cycle (fixes bug #112)
283 persson 1858 - added support for the "fine tune" and "pitch bend range"
284     instrument-level gig parameters
285     - fixed minor artifacts in pitch bend handling
286 schoenebeck 1860 - added support for GS Reset SysEx message
287 persson 1862 - allow gig files to use unlimited downward pitch shifting
288     - added a limit check for upward pitch shifting
289 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
290     note was silent
291 persson 1923 - fixed crash happening when a pitch bend event arrived at the
292     same time a new instrument was loading
293 persson 1644
294 schoenebeck 1687 * LSCP server:
295     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
296     react on MIDI data arriving on certain sampler channels (so far only
297     Note-On and Note-Off events are sent via this LSCP event)
298 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
299     react on MIDI data arriving on certain MIDI input devices (so far only
300     Note-On and Note-Off events are sent via this LSCP event)
301 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
302     SET DB_INSTRUMENT FILE_PATH
303 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
304     frontends to send MIDI messages to specific sampler channel
305     - added two additional fields to GET FILE INSTRUMENT INFO command -
306     KEY_BINDINGS and KEYSWITCH_BINDINGS
307 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
308     was incorrect
309 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
310 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
311     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
312     be triggered respectively
313     - added new LSCP command "SET STREAMS" to globally alter the maximum
314     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
315     which will be triggered respectively
316 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
317     a gigedit file dialog is opened)
318 iliev 1848 - close all connections when LSCPServer is deleted
319 iliev 1882 - hard close of all sockets on exit
320 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
321     driver
322 schoenebeck 1687

333     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
334     GET MIDI_INPUT_DRIVER INFO
335     GET MIDI_INPUT_DRIVER_PARAMETER INFO

337 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
338 iliev 1847 - fixed crash when changing the audio output device of a sampler
339     channel with loaded instrument and start playing notes
340 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
341 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
342     PowerPC, which probably could cause crashes on that platform
343 persson 1889 - fixed a memory management error which could cause a crash when a
344     plugin was unloaded
345 persson 1896 - bugfix: two private structs had the same name, which could cause

351 schoenebeck 1560 Version 0.5.1 (6 December 2007)
352 schoenebeck 1454
353     * packaging changes:
354     - added autoconf checks for pthread library
355     - added autoconf check for pthread bug found on certain NPTL-enabled
356     glibc versions (see Gentoo bug report #194076)
357 senoner 1502 - added autoconf checks for MS Windows
358 schoenebeck 1454
359 persson 1455 * general changes:
360     - bugfix: the thread used by an editor plugin didn't die when the
361     editor closed
362 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
363     out all the space. operator--() did not apply size_mask after
364     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
365     order to avoid problems with the _NonVolatileReader functions.
366     - bugfix: Stream.h: added a missing divide by BytesPerSample in
367     GetWriteSpace(). Since this function is currently only used in
368     the stream's qsort() compare function, it didn't trigger any
369     bugs.
370     - Resampler.h, Synthesizer.h: cubic interpolation now works in
371     24bit mode too. Faster method to read 24bit words on little
372     endian machines (x86): replaced 3 byte reads + shifts with a 1
373     unaligned 32bit read and shift
374     - experimental support for MS Windows (MIDI input via MME, AUDIO
375     output via ASIO)
376     - made handling of SIGINT signal (Ctrl-C) a bit more robust
377 iliev 1541 - support for monitoring the total number of active disk streams
378     (new LSCP commands: GET TOTAL_STREAM_COUNT,
379     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
380 persson 1455
381 senoner 1500 * AUDIO driver:
382 persson 1534 - added Windows ASIO low latency audio driver
383 senoner 1500
384 senoner 1485 * MIDI driver:
385 schoenebeck 1495 - added MME Windows MIDI driver
386 senoner 1485
387 schoenebeck 1471 * LSCP server:
388     - added support for Windows style path / filenames, however with
389     forward slash path separators instead of backslash
390     (i.e. "C:/foo/bar.gig")
391 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
392     apostrophes as well
393 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
394     "LIST FILE INSTRUMENTS <file>" and
395     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
396     about an arbitrary instrument file on the system where the sampler is
397     running on
398 schoenebeck 1471
399 schoenebeck 1424 Version 0.5.0 (15 October 2007)
400 schoenebeck 947
401 schoenebeck 1065 * packaging changes:
402 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
403     API header files anymore
404 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
405     the Doxygen API documentation (explicitly listed in Doxyfile.in)
406 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
407     capable to execute our autoconf environment, thus no need anymore
408     to maintain the compile time configuration file (osx/version.h) for
409     OSX manually (patch by Toshi Nagata)
410 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
411     parameters
412 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
413     C++ API header files, all implementation internal global definitions
414     are now in global_private.h
415     - atomic.h is not exposed to the C++ API anymore
416     - no need to include config.h anymore for using LS's API header files
417     - fixed warnings in API doc generation
418 schoenebeck 1065
419 schoenebeck 947 * general changes:
420     - replaced the old, confusing MIDI program change mechanism by a
421     flexible MIDI instrument mapper which allows to map arbitrary
422 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
423 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
424     loaded on the respective channel when such MIDI program change
425     messages arrive, beside that, each entry allows to define a life-time
426     strategy for the instrument, so the user can define whether the
427     instrument should i.e. be permanently loaded (to be able to switch
428     quickly among sounds) or i.e. loaded just on demand when the
429     respective program change arrives (to safe RAM space), as well as a
430     global volume factor for each entry, so the user can adjust the volume
431     dynamic of his mapped instrument collection without having to modify
432 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
433     MIDI instrument maps and assign each sampler channel individually
434     a certain map, so that i.e. separation of normal instruments and
435     drumkits is possible
436 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
437     MIDI instrument maps, MIDI instruments, FX sends, global volume.
438 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
439     due to a constant size RingBuffer FIFO which is now replaced by a
440     dynamic (unlimited) size std::list FIFO
441 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
442     output channels for being processed by external effect processors
443     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
444     controllers
445 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
446 iliev 1130 - Implemented new, improved notification system
447 schoenebeck 1149 - fixed compilation errors regarding OSX
448     (patch by Toshi Nagata)
449 iliev 1161 - implemented instruments database
450 iliev 1345 - added support for escape sequences to the instruments database
451 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
452     within the sampler's process (by using instrument editor plugins),
453     you'll notice the new "Registered instrument editors:" message on
454 schoenebeck 1407 startup, added a new LSCP command:
455     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
456 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
457     given sampler channel, the plugin path can be overridden at compile
458     time with ./configure --enable-plugin-dir=/some/dir
459 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
460     in the sampler's process to safely edit instruments while playing
461     without a crash (hopefully) by either suspending single regions
462     wherever possible or if unavoidable whole engine(s)
463 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
464     policy and priority on thread level, set a minimum stack size for
465     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
466     threads simply inherited properties of starting thread instead of
467     setting their own policy and priority
468 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
469     main process did not wait for the stack trace process to finish
470     its output
471 persson 1248 - fixed some minor memory leaks
472 schoenebeck 1259 - reenabled assembly features support, at the moment only for
473     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
474 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
475     register, to avoid relocations in the text segment at runtime)
476 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
477 schoenebeck 947
478     * MIDI driver:
479     - dispatch bank select (MSB and LSB) messages
480    
481 schoenebeck 1049 * audio driver:
482     - the ALSA audio output driver parameters now reflect the correct
483     parameter value ranges for the respective selected sound card
484     (patch by Till Wimmer, a bit fixed and extended)
485    
486 persson 951 * Gigasampler format engine:
487     - if a filter is used and EG2 finishes before EG1, let the voice
488     die when EG2 has finished (this fixes a problem with clicks and
489     voice starvation for some gigs)
490 persson 1038 - playback is no longer disabled during instrument loading
491     - all notes playing on a channel that changes its instrument keep
492     playing with the old instrument until they get a note off
493     command
494 persson 1039 - EG fix: a release value of zero could cause noises or crash
495 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
496 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
497     above max sustain level, which means that there is a decay phase
498     even if sustain is 100%
499 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
500     noises or crashes
501 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
502 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
503     supplied to the configure script (fixes #46)
504 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
505     instead of a fix value
506 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
507     127 (solo mode) only kill voices if the respective mode really
508     changed
509 persson 951
510 schoenebeck 1244 * LSCP server:
511     - fixed compile time error for old Bison versions
512     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
513 schoenebeck 1245 - parser now supports extended ASCII character set
514     (up to ASCII code 255, i.e. includes now umlauts and accents)
515     - filename arguments in LSCP commands now allow to use escape
516     sequences, that is directly literal as one of: \', \", \\, \n, \r,
517     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
518     code value like \xf2) (fixes bug #24)
519 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
520     least one of their text-based parameters (i.e. name, description):
521     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
522     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
523     "SET DB_INSTRUMENT_DIRECTORY NAME",
524     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
525     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
526     "FIND DB_INSTRUMENT_DIRECTORIES"
527 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
528     occured, the unexpected character and the actually expected, possible
529     character(s), the latter only if less than 5 possibilities)
530 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
531     settings
532 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
533     of strings were treated as being one string containing commas
534     (fixes #57)
535 schoenebeck 1244
536 iliev 959 * Bug fixes:
537     - fixed crash occurring on certain LSCP scripts (Bug 39)
538 persson 1038 - another thread safety fix for lscp "load engine" and "set
539     channel audio output device"
540 iliev 1283 - fixed a crash which occurs when reassigning the same engine
541     on a sampler channel with connected MIDI device
542 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
543     device connected to a sampler channel to number less then or equal
544     to the index of the port to which the sampler channel is connected.
545 iliev 1296 - The previous bindings were not been disconnected when altering
546     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
547     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
548 iliev 1297 - The active stream/voice count statistic was incorrect.
549 iliev 1298 - notification events were not been sent for some sampler
550     channel changes
551 iliev 1305 - added default min and max values to restrict the number of allowed
552     audio output channels and MIDI input ports
553 iliev 1306 - the connection to the PCM interface is now closed when destroying
554     an audio output device
555 schoenebeck 1332 - files with slash in their path or filename could not be loaded
556 iliev 959
557 schoenebeck 1221 * test cases:
558     - updated and fixed (haven't been touched in a while)
559    
560 schoenebeck 937 Version 0.4.0 (24 November 2006)
561 persson 696
562 schoenebeck 697 * packaging changes:
563 capela 868 - changed deprecated copyright attribute to license; added ldconfig
564     to post-(un)install steps; added devel package for liblinuxsampler;
565     to linuxsampler.spec (RPM)
566 schoenebeck 697 - install necessary development header files for allowing 3rd party
567     applications to link against liblinuxsampler
568     - liblinuxsampler's API documentation can be generated with 'make docs'
569     (Doxygen required)
570 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
571     implementation (currently either an integer math solution or a
572     di-harmonic approximation), automatic detection can be overriden
573     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
574     configure script argument though (mandatory for cross-compilation)
575 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
576     provided some on his own (as CXXFLAGS)
577 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
578     messages
579 schoenebeck 852 - added compile time options to allow disabling the various audio and
580     MIDI drivers
581 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
582     (patch by Ebrahim Mayat)
583 schoenebeck 697
584 persson 696 * Gigasampler format engine:
585 schoenebeck 738 - extensive synthesis optimization
586     (reimplementation of EGs and LFO(s), removed synthesis parameter
587     prerendering and the synthesis parameter matrix in general, splitting
588     each audio fragment into subfragments now where each subfragment uses
589 persson 830 constant pitch and filter coefficients. The volume coefficient is
590     linearly interpolated inside a subfragment, unless
591     --disable-interpolate-volume is set.)
592 persson 696 - fine tuning of the EG modulation parameters
593 persson 729 - improved filter cutoff calculation by adding support for the
594     following gig parameters: Cutoff freq (used when no cutoff
595     controller is defined), Control invert, Minimum cutoff, Velocity
596 persson 791 curve and Velocity range. The keyboard tracking now scales
597     cutoff frequency instead of resonance.
598 persson 877 - added support for gig parameter Resonance.
599 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
600 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
601     which can be overridden with --enable-global-attenuation
602 persson 783 - EG fixes: made the length of "attack hold" stage more
603     accurate. Release stage can now start before attack stage
604 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
605     time now has a minimal value to prevent clicks.
606 persson 799 - fixed pitch changes larger than one octave
607 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
608     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
609     all modes can be altered via standard GM messages, that is CC5 for
610     altering portamento time, CC65 for enabling / disabling portamento
611     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
612 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
613     parameter) and crossfade
614 persson 831 - added support for the "attenuation controller threshold" gig
615     parameter
616 persson 832 - added smoothing of volume changes caused by control change
617     messages
618 persson 865 - sample loop parameters are now taken from the DimensionRegion
619     instead of the wave chunk
620     - fixed keyswitching for v3 gigs with a number of keyswitch splits
621     not equal to a power of two
622 persson 877 - reimplementation of the filter algorithm. The new filter is more
623     accurate and supports all gig filter types, including bandreject
624     and lowpass turbo.
625 persson 903 - real support for 24 bit samples - samples are not truncated to
626     16 bits anymore
627     - support for aftertouch (channel pressure, not polyphonic
628     aftertouch)
629 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
630     amplifying from 0)
631 persson 696
632 schoenebeck 711 * LSCP server:
633     - fixed application exit on broken pipe error (fixes bug #20)
634 iliev 793 - fixed the notification messages delay due to lack of
635     network activity (fixes bug #26)
636 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
637     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
638 schoenebeck 711
639 schoenebeck 838 * audio driver:
640     - added aRts audio output driver (by no means RT safe)
641    
642 schoenebeck 775 * MIDI driver:
643     - fixed legacy sysex code which caused dispatching of MIDI SysEx
644     messages several times instead of once
645 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
646     for events (i.e. for offline rendering based MIDI drivers)
647 persson 922 - added checks for bad MIDI data
648 schoenebeck 775
649 schoenebeck 900 * linuxsampler application:
650     - show available sampler engine types on startup
651    
652 schoenebeck 705 * general changes:
653     - support for muting sampler channels and solo mode of the same, two new
654     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
655     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
656     introduced for this, the behavior is the same like on a mixer console
657 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
658     --enable-process-muted-channels which can be used to enable the
659     processing of muted channels.
660 iliev 777 - support for sostenuto pedal
661 iliev 779 - support for monitoring the total number of active voices
662 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
663     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
664 persson 835 - fixed some memory management errors
665 persson 841 - fixed some concurrency problems that could lead to crashes when
666     LSCP commands were executed
667 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
668     sampler channel (fixes bug #36)
669 schoenebeck 705
670 schoenebeck 692 Version 0.3.3 (15 July 2005)
671 schoenebeck 686
672     * packaging changes:
673     - fixed compilation with gcc 4.0
674    
675 schoenebeck 687 * Gigasampler format engine:
676     - LFO preprocessing was performed even though the respective LFO was
677     disabled by the instrument patch (minor efficiency fix)
678 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
679     for volume ramp downs in the same fragment (needed for current voice
680     stealing implementation) then simply inform the user with a warning
681     about possible click sounds and reduce the volume ramp down
682     appropriately instead of cancelling the audio device connection
683 schoenebeck 687
684 schoenebeck 677 Version 0.3.2 (24 June 2005)
685 schoenebeck 609
686     * packaging changes:
687     - updated autotools build files to compile on OS X
688     (conditional compilation of CoreMIDI and MidiShare drivers)
689 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
690     './configure --disable-asm' (definitely not recommended)
691 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
692     - require automake (>= 1.5) for 'make -f Makefile.cvs'
693     (due to 'dist-bzip2' automake option)
694 schoenebeck 649
695     * Gigasampler format engine:
696     - support for the gig parameters for "release velocity response" curves
697     - fine tuning of the EGADSR envelope
698     - volume of release triggered samples now depends on note-on velocity,
699     note length and gig parameter "release trigger decay" instead of
700     note-off velocity.
701 schoenebeck 663 - revised voice stealing
702     (fixes crash and endless loop caused by voice stealing)
703 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
704 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
705     instead of when the respective voice is actually launched
706     (fixes undefined behavior if stolen voices belonged to a key group -
707     this case was followed by a "killed voice survived" error message)
708 schoenebeck 669 - fixed minor issue with null/silence samples
709     (those stole voices even though they don't need a voice at all which
710     resulted in "voice stealing didn't work out" messages)
711 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
712     instrument or audio output device change
713 schoenebeck 654
714 schoenebeck 620 * LSCP server:
715 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
716 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
717 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
718 schoenebeck 609
719 schoenebeck 668 * linuxsampler application:
720     - added command line parameters --lscp-addr and --lscp-port to override
721     default IP address and port of LSCP server
722    
723 schoenebeck 579 Version 0.3.1 (24 May 2005)
724    
725     * initial release
