* implemented Roland GS NRPN 1ArrH which allows to set volume per note
* implemented Roland GS NRPN 1CrrH which allows to set pan per note
* implemented Roland GS NRPN 1DrrH which allows to set reverb send per
  note (in this implementation of the sampler its simply hard routed to
  the 1st effect send of the sampler channel, no matter what the actual
  effect type is)
* implemented Roland GS NRPN 1ErrH which allows to set chorus send per
  note (in this implementation of the sampler its simply hard routed to
  the 2nd effect send of the sampler channel, no matter what the actual
  effect type is)
* bumped version to 1.0.0cvs4

121     unnecessarily long after an update
122 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
123     events (e.g. to highlight the pressed keys on the virtual keyboard

139 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
140     be switched on by command line option "--stacktrace" (the automatic
141     stacktrace mechanism seems to be broken on most systems at the moment)
142 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
143     a pointer to the launched InstrumentEditor object
144 schoenebeck 1876 - added optional 3rd party user data parameter for following
145     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
146     InstrumentEditor::Launch(),

165 persson 1748 jack_client_new
166 iliev 1829 - added (experimental) CoreAudio driver
167 persson 1888 - applied old fixes to the ASIO driver that were included in the
168     previous binary release but accidentally never committed to CVS
169     (fixes #117)
170 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
171     win64)
172 persson 1895 - VST: added support for sample rate and buffer size changes
173     - VST: close editor (Fantasia) when the VST is removed

182     AudioChannel::CopyTo() methods using GCC vector exensions
183     (if available)
184 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
185     exception when getting parameters from a disconnected device
186 schoenebeck 1599
187 persson 1651 * MIDI driver:
188     - added JACK MIDI driver
189 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
190     want to (mis)use it for some purpose ("fixed" in all current MIDI
191     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
192 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
193 persson 1887 CoreMidi or AU
194 persson 1889 - fixed mingw-w64 compilation error in MME driver
195 persson 1924 - made program change handling in MIDI thread real-time safe by

206 persson 1908 - work-around for missing fnmatch function on Windows to make
207     instrument database compilable
208 schoenebeck 1930 - added instrument database support on Windows
209     works with both standalone mode and VST plugin.
210     the instruments DB file is located in
211     %USERPROFILE%\.linuxsampler\instruments.db which allows different
212     databases for each windows user
213     if no DB is present it automatically creates the .linuxsampler subdir
214     and then creates an empty DB
215 persson 1943 - fixed recursive import, which was broken on Windows
216 iliev 1603
217 persson 1644 * Gigasampler format engine:
218     - fixed a memory leak that could happen when a channel was deleted
219     while notes were playing
220 persson 1646 - made it possible to load an instrument even if the audio thread
221     isn't running
222 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
223     enough for piano gigs with pedal noise samples
224 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
225     respective FX send MIDI controller was used
226 schoenebeck 1724 - added support for GM global device volume SysEx message
227 schoenebeck 1762 (can be selected at compile time to either apply globally to the
228     whole sampler [default] or only to the sampler channels that are
229     connected to the respective MIDI input port the SysEx message arrived
230     on)
231 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
232     sometimes wrongly killed in the same buffer, causing no sound to
233     be played
234 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
235     which is usally used to switch a part between chromatic sounds and
236     drumkit sounds (as opposed to their common default setting of MIDI
237     part 10 being a drumkit part and all other ones chromatic parts), in
238     LS however one can switch between the first 16 MIDI instrument maps
239     defined for the sampler
240 persson 1764 - made it possible to create multiple sample channels even if the
241     audio thread isn't running
242 persson 1844 - fixed crash when removing channel with active voices (#116)
243 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
244     un-cache the respective sample if it's really not used by any
245     sampler engine anymore
246     - re-cache samples in case they were changed by an instrument editor,
247     e.g. when a sample was added while playing (#82)
248 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
249     same time stamp as the voice's note-on event and occured both in the
250     same audio fragment cycle (fixes bug #112)
251 persson 1858 - added support for the "fine tune" and "pitch bend range"
252     instrument-level gig parameters
253     - fixed minor artifacts in pitch bend handling
254 schoenebeck 1860 - added support for GS Reset SysEx message
255 persson 1862 - allow gig files to use unlimited downward pitch shifting
256     - added a limit check for upward pitch shifting
257 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
258     note was silent
259 persson 1923 - fixed crash happening when a pitch bend event arrived at the
260     same time a new instrument was loading
261 persson 1644
262 schoenebeck 1687 * LSCP server:
263     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
264     react on MIDI data arriving on certain sampler channels (so far only
265     Note-On and Note-Off events are sent via this LSCP event)
266 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
267     react on MIDI data arriving on certain MIDI input devices (so far only
268     Note-On and Note-Off events are sent via this LSCP event)
269 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
270     SET DB_INSTRUMENT FILE_PATH
271 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
272     frontends to send MIDI messages to specific sampler channel
273     - added two additional fields to GET FILE INSTRUMENT INFO command -
274     KEY_BINDINGS and KEYSWITCH_BINDINGS
275 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
276     was incorrect
277 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
278 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
279     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
280     be triggered respectively
281     - added new LSCP command "SET STREAMS" to globally alter the maximum
282     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
283     which will be triggered respectively
284 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
285     a gigedit file dialog is opened)
286 iliev 1848 - close all connections when LSCPServer is deleted
287 iliev 1882 - hard close of all sockets on exit
288 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
289     driver
290 schoenebeck 1687
291 iliev 1761 * Bug fixes:
292     - fixed a crash which occurs when removing a sampler channel waiting
293     to start instrument loading after another channel
294 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
295     instrument loading in progress (bug #113)
296 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
297     instrument with PERSISTENT load mode
298 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

301     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
302     GET MIDI_INPUT_DRIVER INFO
303     GET MIDI_INPUT_DRIVER_PARAMETER INFO
304     - fixed possible compilation error when sqlite is not present
305 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
306 iliev 1847 - fixed crash when changing the audio output device of a sampler
307     channel with loaded instrument and start playing notes
308 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
309 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
310     PowerPC, which probably could cause crashes on that platform
311 persson 1889 - fixed a memory management error which could cause a crash when a
312     plugin was unloaded
313 persson 1896 - bugfix: two private structs had the same name, which could cause
314     problems if the linker chose the wrong constructor
315 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
316     Windows
317 iliev 1761
318    
319 schoenebeck 1560 Version 0.5.1 (6 December 2007)
320 schoenebeck 1454
321     * packaging changes:
322     - added autoconf checks for pthread library
323     - added autoconf check for pthread bug found on certain NPTL-enabled
324     glibc versions (see Gentoo bug report #194076)
325 senoner 1502 - added autoconf checks for MS Windows
326 schoenebeck 1454
327 persson 1455 * general changes:
328     - bugfix: the thread used by an editor plugin didn't die when the
329     editor closed
330 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
331     out all the space. operator--() did not apply size_mask after
332     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
333     order to avoid problems with the _NonVolatileReader functions.
334     - bugfix: Stream.h: added a missing divide by BytesPerSample in
335     GetWriteSpace(). Since this function is currently only used in
336     the stream's qsort() compare function, it didn't trigger any
337     bugs.
338     - Resampler.h, Synthesizer.h: cubic interpolation now works in
339     24bit mode too. Faster method to read 24bit words on little
340     endian machines (x86): replaced 3 byte reads + shifts with a 1
341     unaligned 32bit read and shift
342     - experimental support for MS Windows (MIDI input via MME, AUDIO
343     output via ASIO)
344     - made handling of SIGINT signal (Ctrl-C) a bit more robust
345 iliev 1541 - support for monitoring the total number of active disk streams
346     (new LSCP commands: GET TOTAL_STREAM_COUNT,
347     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
348 persson 1455
349 senoner 1500 * AUDIO driver:

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