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 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
19     dimension zones is not a power of two
20     - made round robin use a counter for each region instead of each
21     key
22    
23 schoenebeck 2047 * SFZ format engine:
24 iliev 2012 - Initial implementation (not usable yet)
25 persson 2055 - added support for v2 multiple stage envelope generators
26     - added a fine-tuned v1 envelope generator instead of using the

29 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
30 persson 2058 - allow non-numerical key values ("C#4" for example)
31     - "key" opcode now sets pitch_keycenter too
32     - fixed error when unloading instrument with same sample used by

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

107     unnecessarily long after an update
108 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
109     events (e.g. to highlight the pressed keys on the virtual keyboard
110     of gigedit)
111 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
112 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
113 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

141 schoenebeck 1599 * audio driver:
142     - removed the nonsense audio channel constraint (which was hard coded to
143     max. 100 audio channels) for most audio drivers
144 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
145     opposed to the LSCP specs
146 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
147     reflected the wrong value

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

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

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