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
14     (patch by Luis Garrido, slightly modified).
15 iliev 2012
16 persson 2043 * Gigasampler format engine:
17     - implemented the "round robin keyboard" dimension
18     - fixed round robin and random dimensions for cases when number of

80 schoenebeck 1599
81 schoenebeck 1639 * packaging changes:
82     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

109     unnecessarily long after an update
110 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
111     events (e.g. to highlight the pressed keys on the virtual keyboard
112     of gigedit)

126 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
127 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
128     be switched on by command line option "--stacktrace" (the automatic
129     stacktrace mechanism seems to be broken on most systems at the moment)
130 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
131     a pointer to the launched InstrumentEditor object
132 schoenebeck 1876 - added optional 3rd party user data parameter for following
133     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

144     - removed the nonsense audio channel constraint (which was hard coded to
145     max. 100 audio channels) for most audio drivers
146 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
147     opposed to the LSCP specs

153 persson 1748 jack_client_new
154 iliev 1829 - added (experimental) CoreAudio driver
155 persson 1888 - applied old fixes to the ASIO driver that were included in the
156     previous binary release but accidentally never committed to CVS
157     (fixes #117)
158 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
159     win64)
160 persson 1895 - VST: added support for sample rate and buffer size changes
161     - VST: close editor (Fantasia) when the VST is removed

170     AudioChannel::CopyTo() methods using GCC vector exensions
171     (if available)
172 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
173     exception when getting parameters from a disconnected device
174 schoenebeck 1599
175 persson 1651 * MIDI driver:
176     - added JACK MIDI driver
177 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
178     want to (mis)use it for some purpose ("fixed" in all current MIDI
179     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
180 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
181 persson 1887 CoreMidi or AU
182 persson 1889 - fixed mingw-w64 compilation error in MME driver
183 persson 1924 - made program change handling in MIDI thread real-time safe by
184     moving the logic to a non-RT thread

195     instrument database compilable
196 schoenebeck 1930 - added instrument database support on Windows
197     works with both standalone mode and VST plugin.
198     the instruments DB file is located in
199     %USERPROFILE%\.linuxsampler\instruments.db which allows different
200     databases for each windows user
201     if no DB is present it automatically creates the .linuxsampler subdir
202     and then creates an empty DB
203 persson 1943 - fixed recursive import, which was broken on Windows
204 iliev 1603
205 persson 1644 * Gigasampler format engine:
206     - fixed a memory leak that could happen when a channel was deleted
207     while notes were playing
208 persson 1646 - made it possible to load an instrument even if the audio thread
209     isn't running
210 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
211     enough for piano gigs with pedal noise samples
212 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
213     respective FX send MIDI controller was used
214 schoenebeck 1724 - added support for GM global device volume SysEx message
215 schoenebeck 1762 (can be selected at compile time to either apply globally to the
216     whole sampler [default] or only to the sampler channels that are
217     connected to the respective MIDI input port the SysEx message arrived
218     on)
219 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
220     sometimes wrongly killed in the same buffer, causing no sound to
221     be played
222 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
223     which is usally used to switch a part between chromatic sounds and
224     drumkit sounds (as opposed to their common default setting of MIDI
225     part 10 being a drumkit part and all other ones chromatic parts), in
226     LS however one can switch between the first 16 MIDI instrument maps
227     defined for the sampler
228 persson 1764 - made it possible to create multiple sample channels even if the
229     audio thread isn't running
230 persson 1844 - fixed crash when removing channel with active voices (#116)
231 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
232     un-cache the respective sample if it's really not used by any
233     sampler engine anymore
234     - re-cache samples in case they were changed by an instrument editor,
235     e.g. when a sample was added while playing (#82)
236 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
237     same time stamp as the voice's note-on event and occured both in the
238     same audio fragment cycle (fixes bug #112)
239 persson 1858 - added support for the "fine tune" and "pitch bend range"
240     instrument-level gig parameters
241     - fixed minor artifacts in pitch bend handling
242 schoenebeck 1860 - added support for GS Reset SysEx message
243 persson 1862 - allow gig files to use unlimited downward pitch shifting
244     - added a limit check for upward pitch shifting
245 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
246     note was silent
247 persson 1923 - fixed crash happening when a pitch bend event arrived at the
248     same time a new instrument was loading
249 persson 1644
250 schoenebeck 1687 * LSCP server:
251     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
252     react on MIDI data arriving on certain sampler channels (so far only
253     Note-On and Note-Off events are sent via this LSCP event)
254 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
255     react on MIDI data arriving on certain MIDI input devices (so far only
256     Note-On and Note-Off events are sent via this LSCP event)
257 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
258     SET DB_INSTRUMENT FILE_PATH
259 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
260     frontends to send MIDI messages to specific sampler channel
261     - added two additional fields to GET FILE INSTRUMENT INFO command -
262     KEY_BINDINGS and KEYSWITCH_BINDINGS
263 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
264     was incorrect
265 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
266 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
267     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
268     be triggered respectively
269     - added new LSCP command "SET STREAMS" to globally alter the maximum
270     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
271     which will be triggered respectively
272 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
273     a gigedit file dialog is opened)
274 iliev 1848 - close all connections when LSCPServer is deleted
275 iliev 1882 - hard close of all sockets on exit
276 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
277     driver
278 schoenebeck 1687
279 iliev 1761 * Bug fixes:
280     - fixed a crash which occurs when removing a sampler channel waiting
281     to start instrument loading after another channel
282 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
283     instrument loading in progress (bug #113)
284 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
285     instrument with PERSISTENT load mode
286 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
287     - fixed memory leaks when issuing the following LSCP commands:
288     GET AUDIO_OUTPUT_DRIVER INFO
289     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
290     GET MIDI_INPUT_DRIVER INFO
291     GET MIDI_INPUT_DRIVER_PARAMETER INFO
292     - fixed possible compilation error when sqlite is not present
293 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
294 iliev 1847 - fixed crash when changing the audio output device of a sampler
295     channel with loaded instrument and start playing notes
296 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
297 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
298     PowerPC, which probably could cause crashes on that platform
299 persson 1889 - fixed a memory management error which could cause a crash when a
300     plugin was unloaded
301 persson 1896 - bugfix: two private structs had the same name, which could cause
302     problems if the linker chose the wrong constructor
303 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
304     Windows
305 iliev 1761
306    
307 schoenebeck 1560 Version 0.5.1 (6 December 2007)
308 schoenebeck 1454
309     * packaging changes:
310     - added autoconf checks for pthread library
311     - added autoconf check for pthread bug found on certain NPTL-enabled
312     glibc versions (see Gentoo bug report #194076)
313 senoner 1502 - added autoconf checks for MS Windows
314 schoenebeck 1454
315 persson 1455 * general changes:
316     - bugfix: the thread used by an editor plugin didn't die when the
317     editor closed
318 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
319     out all the space. operator--() did not apply size_mask after
320     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
321     order to avoid problems with the _NonVolatileReader functions.
322     - bugfix: Stream.h: added a missing divide by BytesPerSample in
323     GetWriteSpace(). Since this function is currently only used in
324     the stream's qsort() compare function, it didn't trigger any
325     bugs.
326     - Resampler.h, Synthesizer.h: cubic interpolation now works in
327     24bit mode too. Faster method to read 24bit words on little
328     endian machines (x86): replaced 3 byte reads + shifts with a 1
329     unaligned 32bit read and shift
330     - experimental support for MS Windows (MIDI input via MME, AUDIO
331     output via ASIO)
332     - made handling of SIGINT signal (Ctrl-C) a bit more robust
333 iliev 1541 - support for monitoring the total number of active disk streams
334     (new LSCP commands: GET TOTAL_STREAM_COUNT,
335     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
336 persson 1455
337 senoner 1500 * AUDIO driver:
338 persson 1534 - added Windows ASIO low latency audio driver
339 senoner 1500
340 senoner 1485 * MIDI driver:
341 schoenebeck 1495 - added MME Windows MIDI driver
342 senoner 1485
343 schoenebeck 1471 * LSCP server:
344     - added support for Windows style path / filenames, however with
345     forward slash path separators instead of backslash
346     (i.e. "C:/foo/bar.gig")
347 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
348     apostrophes as well
349 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
350     "LIST FILE INSTRUMENTS <file>" and
351     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
352     about an arbitrary instrument file on the system where the sampler is
353     running on
354 schoenebeck 1471
355 schoenebeck 1424 Version 0.5.0 (15 October 2007)
356 schoenebeck 947
357 schoenebeck 1065 * packaging changes:
358 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
359     API header files anymore
360 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
361     the Doxygen API documentation (explicitly listed in Doxyfile.in)
362 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
363     capable to execute our autoconf environment, thus no need anymore
364     to maintain the compile time configuration file (osx/version.h) for
365     OSX manually (patch by Toshi Nagata)
366 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
367     parameters
368 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
369     C++ API header files, all implementation internal global definitions
370     are now in global_private.h
371     - atomic.h is not exposed to the C++ API anymore
372     - no need to include config.h anymore for using LS's API header files
373     - fixed warnings in API doc generation
374 schoenebeck 1065
375 schoenebeck 947 * general changes:
376     - replaced the old, confusing MIDI program change mechanism by a
377     flexible MIDI instrument mapper which allows to map arbitrary
378 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
379 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
380     loaded on the respective channel when such MIDI program change
381     messages arrive, beside that, each entry allows to define a life-time
382     strategy for the instrument, so the user can define whether the
383     instrument should i.e. be permanently loaded (to be able to switch
384     quickly among sounds) or i.e. loaded just on demand when the
385     respective program change arrives (to safe RAM space), as well as a
386     global volume factor for each entry, so the user can adjust the volume
387     dynamic of his mapped instrument collection without having to modify
388 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
389     MIDI instrument maps and assign each sampler channel individually
390     a certain map, so that i.e. separation of normal instruments and
391     drumkits is possible
392 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
393     MIDI instrument maps, MIDI instruments, FX sends, global volume.
394 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
395     due to a constant size RingBuffer FIFO which is now replaced by a
396     dynamic (unlimited) size std::list FIFO
397 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
398     output channels for being processed by external effect processors
399     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
400     controllers
401 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
402 iliev 1130 - Implemented new, improved notification system
403 schoenebeck 1149 - fixed compilation errors regarding OSX
404     (patch by Toshi Nagata)
405 iliev 1161 - implemented instruments database
406 iliev 1345 - added support for escape sequences to the instruments database
407 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
408     within the sampler's process (by using instrument editor plugins),
409     you'll notice the new "Registered instrument editors:" message on
410 schoenebeck 1407 startup, added a new LSCP command:
411     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
412 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
413     given sampler channel, the plugin path can be overridden at compile
414     time with ./configure --enable-plugin-dir=/some/dir
415 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
416     in the sampler's process to safely edit instruments while playing
417     without a crash (hopefully) by either suspending single regions
418     wherever possible or if unavoidable whole engine(s)
419 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
420     policy and priority on thread level, set a minimum stack size for
421     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
422     threads simply inherited properties of starting thread instead of
423     setting their own policy and priority
424 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
425     main process did not wait for the stack trace process to finish
426     its output
427 persson 1248 - fixed some minor memory leaks
428 schoenebeck 1259 - reenabled assembly features support, at the moment only for
429     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
430 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
431     register, to avoid relocations in the text segment at runtime)
432 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
433 schoenebeck 947
434     * MIDI driver:
435     - dispatch bank select (MSB and LSB) messages
436    
437 schoenebeck 1049 * audio driver:
438     - the ALSA audio output driver parameters now reflect the correct
439     parameter value ranges for the respective selected sound card
440     (patch by Till Wimmer, a bit fixed and extended)
441    
442 persson 951 * Gigasampler format engine:
443     - if a filter is used and EG2 finishes before EG1, let the voice
444     die when EG2 has finished (this fixes a problem with clicks and
445     voice starvation for some gigs)
446 persson 1038 - playback is no longer disabled during instrument loading
447     - all notes playing on a channel that changes its instrument keep
448     playing with the old instrument until they get a note off
449     command
450 persson 1039 - EG fix: a release value of zero could cause noises or crash
451 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
452 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
453     above max sustain level, which means that there is a decay phase
454     even if sustain is 100%
455 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
456     noises or crashes
457 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
458 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
459     supplied to the configure script (fixes #46)
460 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
461     instead of a fix value
462 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
463     127 (solo mode) only kill voices if the respective mode really
464     changed
465 persson 951
466 schoenebeck 1244 * LSCP server:
467     - fixed compile time error for old Bison versions
468     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
469 schoenebeck 1245 - parser now supports extended ASCII character set
470     (up to ASCII code 255, i.e. includes now umlauts and accents)
471     - filename arguments in LSCP commands now allow to use escape
472     sequences, that is directly literal as one of: \', \", \\, \n, \r,
473     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
474     code value like \xf2) (fixes bug #24)
475 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
476     least one of their text-based parameters (i.e. name, description):
477     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
478     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
479     "SET DB_INSTRUMENT_DIRECTORY NAME",
480     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
481     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
482     "FIND DB_INSTRUMENT_DIRECTORIES"
483 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
484     occured, the unexpected character and the actually expected, possible
485     character(s), the latter only if less than 5 possibilities)
486 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
487     settings
488 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
489     of strings were treated as being one string containing commas
490     (fixes #57)
491 schoenebeck 1244
492 iliev 959 * Bug fixes:
493     - fixed crash occurring on certain LSCP scripts (Bug 39)
494 persson 1038 - another thread safety fix for lscp "load engine" and "set
495     channel audio output device"
496 iliev 1283 - fixed a crash which occurs when reassigning the same engine
497     on a sampler channel with connected MIDI device
498 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
499     device connected to a sampler channel to number less then or equal
500     to the index of the port to which the sampler channel is connected.
501 iliev 1296 - The previous bindings were not been disconnected when altering
502     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
503     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
504 iliev 1297 - The active stream/voice count statistic was incorrect.
505 iliev 1298 - notification events were not been sent for some sampler
506     channel changes
507 iliev 1305 - added default min and max values to restrict the number of allowed
508     audio output channels and MIDI input ports
509 iliev 1306 - the connection to the PCM interface is now closed when destroying
510     an audio output device
511 schoenebeck 1332 - files with slash in their path or filename could not be loaded
512 iliev 959
513 schoenebeck 1221 * test cases:
514     - updated and fixed (haven't been touched in a while)
515    
516 schoenebeck 937 Version 0.4.0 (24 November 2006)
517 persson 696
518 schoenebeck 697 * packaging changes:
519 capela 868 - changed deprecated copyright attribute to license; added ldconfig
520     to post-(un)install steps; added devel package for liblinuxsampler;
521     to linuxsampler.spec (RPM)
522 schoenebeck 697 - install necessary development header files for allowing 3rd party
523     applications to link against liblinuxsampler
524     - liblinuxsampler's API documentation can be generated with 'make docs'
525     (Doxygen required)
526 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
527     implementation (currently either an integer math solution or a
528     di-harmonic approximation), automatic detection can be overriden
529     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
530     configure script argument though (mandatory for cross-compilation)
531 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
532     provided some on his own (as CXXFLAGS)
533 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
534     messages
535 schoenebeck 852 - added compile time options to allow disabling the various audio and
536     MIDI drivers
537 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
538     (patch by Ebrahim Mayat)
539 schoenebeck 697
540 persson 696 * Gigasampler format engine:
541 schoenebeck 738 - extensive synthesis optimization
542     (reimplementation of EGs and LFO(s), removed synthesis parameter
543     prerendering and the synthesis parameter matrix in general, splitting
544     each audio fragment into subfragments now where each subfragment uses
545 persson 830 constant pitch and filter coefficients. The volume coefficient is
546     linearly interpolated inside a subfragment, unless
547     --disable-interpolate-volume is set.)
548 persson 696 - fine tuning of the EG modulation parameters
549 persson 729 - improved filter cutoff calculation by adding support for the
550     following gig parameters: Cutoff freq (used when no cutoff
551     controller is defined), Control invert, Minimum cutoff, Velocity
552 persson 791 curve and Velocity range. The keyboard tracking now scales
553     cutoff frequency instead of resonance.
554 persson 877 - added support for gig parameter Resonance.
555 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
556 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
557     which can be overridden with --enable-global-attenuation
558 persson 783 - EG fixes: made the length of "attack hold" stage more
559     accurate. Release stage can now start before attack stage
560 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
561     time now has a minimal value to prevent clicks.
562 persson 799 - fixed pitch changes larger than one octave
563 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
564     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
565     all modes can be altered via standard GM messages, that is CC5 for
566     altering portamento time, CC65 for enabling / disabling portamento
567     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
568 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
569     parameter) and crossfade
570 persson 831 - added support for the "attenuation controller threshold" gig
571     parameter
572 persson 832 - added smoothing of volume changes caused by control change
573     messages
574 persson 865 - sample loop parameters are now taken from the DimensionRegion
575     instead of the wave chunk
576     - fixed keyswitching for v3 gigs with a number of keyswitch splits
577     not equal to a power of two
578 persson 877 - reimplementation of the filter algorithm. The new filter is more
579     accurate and supports all gig filter types, including bandreject
580     and lowpass turbo.
581 persson 903 - real support for 24 bit samples - samples are not truncated to
582     16 bits anymore
583     - support for aftertouch (channel pressure, not polyphonic
584     aftertouch)
585 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
586     amplifying from 0)
587 persson 696
588 schoenebeck 711 * LSCP server:
589     - fixed application exit on broken pipe error (fixes bug #20)
590 iliev 793 - fixed the notification messages delay due to lack of
591     network activity (fixes bug #26)
592 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
593     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
594 schoenebeck 711
595 schoenebeck 838 * audio driver:
596     - added aRts audio output driver (by no means RT safe)
597    
598 schoenebeck 775 * MIDI driver:
599     - fixed legacy sysex code which caused dispatching of MIDI SysEx
600     messages several times instead of once
601 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
602     for events (i.e. for offline rendering based MIDI drivers)
603 persson 922 - added checks for bad MIDI data
604 schoenebeck 775
605 schoenebeck 900 * linuxsampler application:
606     - show available sampler engine types on startup
607    
608 schoenebeck 705 * general changes:
609     - support for muting sampler channels and solo mode of the same, two new
610     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
611     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
612     introduced for this, the behavior is the same like on a mixer console
613 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
614     --enable-process-muted-channels which can be used to enable the
615     processing of muted channels.
616 iliev 777 - support for sostenuto pedal
617 iliev 779 - support for monitoring the total number of active voices
618 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
619     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
620 persson 835 - fixed some memory management errors
621 persson 841 - fixed some concurrency problems that could lead to crashes when
622     LSCP commands were executed
623 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
624     sampler channel (fixes bug #36)
625 schoenebeck 705
626 schoenebeck 692 Version 0.3.3 (15 July 2005)
627 schoenebeck 686
628     * packaging changes:
629     - fixed compilation with gcc 4.0
630    
631 schoenebeck 687 * Gigasampler format engine:
632     - LFO preprocessing was performed even though the respective LFO was
633     disabled by the instrument patch (minor efficiency fix)
634 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
635     for volume ramp downs in the same fragment (needed for current voice
636     stealing implementation) then simply inform the user with a warning
637     about possible click sounds and reduce the volume ramp down
638     appropriately instead of cancelling the audio device connection
639 schoenebeck 687
640 schoenebeck 677 Version 0.3.2 (24 June 2005)
641 schoenebeck 609
642     * packaging changes:
643     - updated autotools build files to compile on OS X
644     (conditional compilation of CoreMIDI and MidiShare drivers)
645 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
646     './configure --disable-asm' (definitely not recommended)
647 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
648     - require automake (>= 1.5) for 'make -f Makefile.cvs'
649     (due to 'dist-bzip2' automake option)
650 schoenebeck 649
651     * Gigasampler format engine:
652     - support for the gig parameters for "release velocity response" curves
653     - fine tuning of the EGADSR envelope
654     - volume of release triggered samples now depends on note-on velocity,
655     note length and gig parameter "release trigger decay" instead of
656     note-off velocity.
657 schoenebeck 663 - revised voice stealing
658     (fixes crash and endless loop caused by voice stealing)
659 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
660 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
661     instead of when the respective voice is actually launched
662     (fixes undefined behavior if stolen voices belonged to a key group -
663     this case was followed by a "killed voice survived" error message)
664 schoenebeck 669 - fixed minor issue with null/silence samples
665     (those stole voices even though they don't need a voice at all which
666     resulted in "voice stealing didn't work out" messages)
667 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
668     instrument or audio output device change
669 schoenebeck 654
670 schoenebeck 620 * LSCP server:
671 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
672 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
673 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
674 schoenebeck 609
675 schoenebeck 668 * linuxsampler application:
676     - added command line parameters --lscp-addr and --lscp-port to override
677     default IP address and port of LSCP server
678    
679 schoenebeck 579 Version 0.3.1 (24 May 2005)
680    
681     * initial release
