* sfz engine: use loop markers from sample file if loop_start and
  loop_end are not set in sfz file

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5    
6     * general changes:
7 iliev 2012 - Refactoring: moved the independent code from
8     the Gigasampler format engine to base classes
9 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
10     respective profiling code is currently broken
11 schoenebeck 2053 - Introduced support for optional environment variable
12     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13     where the sampler shall look for instrument editor plugins
14     (patch by Luis Garrido, slightly modified).
15 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
16     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
17     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
18     note (in this implementation of the sampler its simply hard routed to
19     the 1st effect send of the sampler channel, no matter what the actual
20     effect type is)
21     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
22     note (in this implementation of the sampler its simply hard routed to
23     the 2nd effect send of the sampler channel, no matter what the actual
24     effect type is)
25 schoenebeck 2124 - implemented support for internal LADSPA effects
26 schoenebeck 2140 - raised limit of program change queue from 100 to 512
27     (as suggested by Alex Stone)

29 persson 2043 * Gigasampler format engine:
30     - implemented the "round robin keyboard" dimension
31     - fixed round robin and random dimensions for cases when number of
32     dimension zones is not a power of two
33     - made round robin use a counter for each region instead of each
34     key
35    
36 schoenebeck 2047 * SFZ format engine:
37 iliev 2012 - Initial implementation (not usable yet)
38 persson 2055 - added support for v2 multiple stage envelope generators
39     - added a fine-tuned v1 envelope generator instead of using the
40     one from the gig engine
41 persson 2058 - fixed memory leak and memory handling errors
42 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
43 persson 2058 - allow non-numerical key values ("C#4" for example)
44     - "key" opcode now sets pitch_keycenter too
45     - fixed error when unloading instrument with same sample used by
46     multiple regions
47     - added some opcode aliases, like loopmode for loop_mode, to be
48     more compatible
49 persson 2061 - added support for trigger=release and rt_decay
50 persson 2063 - added support for off_mode=normal
51 persson 2072 - added support for random, seq_position, seq_length and volume

61     - fixed a bug that could cause voice stealing to fail
62 persson 2106 - optimized sample lookup
63 persson 2114 - improved support for exclusive groups (group, off_by and
64     off_mode)
65 persson 2115 - added support for controller triggered regions (on_locc/on_hicc)
66     - added support for loop_mode=one_shot
67 persson 2119 - fixed playback of 16 bit wav files on big endian CPUs

80 persson 2045 - VST bugfix: If the host called resume() before and after
81     changing sample rate or block size, the number of channels was
82     incorrectly set to two. This caused silence in Cubase 5.
83 persson 2165 - save engine type (gig, sfz or sf2) in plugin state
84     - VST: when opening Fantasia, look for both 32 and 64 bit Java on
85     64 bit Windows

134 persson 2162 - bugfix: playing a note while changing the instrument could cause
135     a crash, or give "Handing back unknown region" error messages
136 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
137     refresh) could cause instruments to be unloaded
138 iliev 2012
139 persson 1957 Version 1.0.0 (31 July 2009)
140 schoenebeck 1599
141 schoenebeck 1639 * packaging changes:
142     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

160 schoenebeck 1639
161 schoenebeck 1601 * general changes:
162     - bugfix: on some POSIX systems instrument editor plugins refused to

164     (fixes bug #70, patch by Ronald Baljeu)
165 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
166     plugin DLL on Windows systems failed

174 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
175 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

177     implementation, which is usually faster)
178 persson 1748 - fixes for audio drivers with varying buffer sizes
179 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
180     VST plugin

187 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
188     be switched on by command line option "--stacktrace" (the automatic
189     stacktrace mechanism seems to be broken on most systems at the moment)
190 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
191     a pointer to the launched InstrumentEditor object
192 schoenebeck 1876 - added optional 3rd party user data parameter for following
193     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
194     InstrumentEditor::Launch(),

196 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
197     model more strictly
198 persson 1895 - fixes for using large audio device buffers
199 persson 1951 - Windows: add the installation directory to the DLL search path

202 schoenebeck 1601
203 schoenebeck 1599 * audio driver:
204     - removed the nonsense audio channel constraint (which was hard coded to
205     max. 100 audio channels) for most audio drivers
206 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
207     opposed to the LSCP specs
208 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
209     reflected the wrong value
210 persson 1644 - fixed a memory management bug in ASIO driver
211 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
212 persson 1777 - JACK: use jack_client_open instead of the deprecated
213 persson 1748 jack_client_new
214 iliev 1829 - added (experimental) CoreAudio driver
215 persson 1888 - applied old fixes to the ASIO driver that were included in the
216     previous binary release but accidentally never committed to CVS
217     (fixes #117)
218 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
219     win64)
220 persson 1895 - VST: added support for sample rate and buffer size changes
221     - VST: close editor (Fantasia) when the VST is removed
222 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

230     AudioChannel::CopyTo() methods using GCC vector exensions
231     (if available)
232 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
233     exception when getting parameters from a disconnected device
234 schoenebeck 1599
235 persson 1651 * MIDI driver:
236     - added JACK MIDI driver
237 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
238     want to (mis)use it for some purpose ("fixed" in all current MIDI
239     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
240 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
241 persson 1887 CoreMidi or AU
242 persson 1889 - fixed mingw-w64 compilation error in MME driver
243 persson 1924 - made program change handling in MIDI thread real-time safe by
244     moving the logic to a non-RT thread

249     to the instruments database
250 iliev 1727 - added support for handling lost files in the instruments database
251 iliev 1781 - Implemented option for adding instruments in separate directories
252     in the instruments database
253     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
254 persson 1908 - work-around for missing fnmatch function on Windows to make
255     instrument database compilable
256 schoenebeck 1930 - added instrument database support on Windows
257     works with both standalone mode and VST plugin.
258     the instruments DB file is located in
259     %USERPROFILE%\.linuxsampler\instruments.db which allows different
260     databases for each windows user
261     if no DB is present it automatically creates the .linuxsampler subdir
262     and then creates an empty DB
263 persson 1943 - fixed recursive import, which was broken on Windows
264 iliev 1603
265 persson 1644 * Gigasampler format engine:
266     - fixed a memory leak that could happen when a channel was deleted
267     while notes were playing
268 persson 1646 - made it possible to load an instrument even if the audio thread
269     isn't running
270 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
271     enough for piano gigs with pedal noise samples
272 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
273     respective FX send MIDI controller was used
274 schoenebeck 1724 - added support for GM global device volume SysEx message
275 schoenebeck 1762 (can be selected at compile time to either apply globally to the
276     whole sampler [default] or only to the sampler channels that are
277     connected to the respective MIDI input port the SysEx message arrived
278     on)
279 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
280     sometimes wrongly killed in the same buffer, causing no sound to
281     be played
282 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
283     which is usally used to switch a part between chromatic sounds and
284     drumkit sounds (as opposed to their common default setting of MIDI
285     part 10 being a drumkit part and all other ones chromatic parts), in
286     LS however one can switch between the first 16 MIDI instrument maps
287     defined for the sampler
288 persson 1764 - made it possible to create multiple sample channels even if the
289     audio thread isn't running
290 persson 1844 - fixed crash when removing channel with active voices (#116)
291 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
292     un-cache the respective sample if it's really not used by any
293     sampler engine anymore
294     - re-cache samples in case they were changed by an instrument editor,
295     e.g. when a sample was added while playing (#82)
296 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
297     same time stamp as the voice's note-on event and occured both in the
298     same audio fragment cycle (fixes bug #112)
299 persson 1858 - added support for the "fine tune" and "pitch bend range"
300     instrument-level gig parameters
301     - fixed minor artifacts in pitch bend handling
302 schoenebeck 1860 - added support for GS Reset SysEx message
303 persson 1862 - allow gig files to use unlimited downward pitch shifting
304     - added a limit check for upward pitch shifting
305 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
306     note was silent
307 persson 1923 - fixed crash happening when a pitch bend event arrived at the
308     same time a new instrument was loading
309 persson 1644
310 schoenebeck 1687 * LSCP server:
311     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
312     react on MIDI data arriving on certain sampler channels (so far only
313     Note-On and Note-Off events are sent via this LSCP event)
314 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
315     react on MIDI data arriving on certain MIDI input devices (so far only
316     Note-On and Note-Off events are sent via this LSCP event)
317 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
318     SET DB_INSTRUMENT FILE_PATH
319 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
320     frontends to send MIDI messages to specific sampler channel
321     - added two additional fields to GET FILE INSTRUMENT INFO command -
322     KEY_BINDINGS and KEYSWITCH_BINDINGS
323 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
324     was incorrect
325 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
326 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
327     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
328     be triggered respectively
329     - added new LSCP command "SET STREAMS" to globally alter the maximum
330     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
331     which will be triggered respectively
332 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
333     a gigedit file dialog is opened)
334 iliev 1848 - close all connections when LSCPServer is deleted
335 iliev 1882 - hard close of all sockets on exit
336 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
337     driver
338 schoenebeck 1687
339 iliev 1761 * Bug fixes:
340     - fixed a crash which occurs when removing a sampler channel waiting
341     to start instrument loading after another channel

349     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
350     GET MIDI_INPUT_DRIVER INFO
351     GET MIDI_INPUT_DRIVER_PARAMETER INFO

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

363 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
364     Windows
365 iliev 1761
366    
367 schoenebeck 1560 Version 0.5.1 (6 December 2007)
368 schoenebeck 1454
369     * packaging changes:
370     - added autoconf checks for pthread library
371     - added autoconf check for pthread bug found on certain NPTL-enabled
372     glibc versions (see Gentoo bug report #194076)
373 senoner 1502 - added autoconf checks for MS Windows
374 schoenebeck 1454
375 persson 1455 * general changes:
376     - bugfix: the thread used by an editor plugin didn't die when the
377     editor closed
378 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
379     out all the space. operator--() did not apply size_mask after
380     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
381     order to avoid problems with the _NonVolatileReader functions.
382     - bugfix: Stream.h: added a missing divide by BytesPerSample in
383     GetWriteSpace(). Since this function is currently only used in
384     the stream's qsort() compare function, it didn't trigger any
385     bugs.
386     - Resampler.h, Synthesizer.h: cubic interpolation now works in
387     24bit mode too. Faster method to read 24bit words on little
388     endian machines (x86): replaced 3 byte reads + shifts with a 1
389     unaligned 32bit read and shift
390     - experimental support for MS Windows (MIDI input via MME, AUDIO
391     output via ASIO)
392     - made handling of SIGINT signal (Ctrl-C) a bit more robust
393 iliev 1541 - support for monitoring the total number of active disk streams
394     (new LSCP commands: GET TOTAL_STREAM_COUNT,
395     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
396 persson 1455
397 senoner 1500 * AUDIO driver:
398 persson 1534 - added Windows ASIO low latency audio driver
399 senoner 1500
400 senoner 1485 * MIDI driver:
401 schoenebeck 1495 - added MME Windows MIDI driver
402 senoner 1485
403 schoenebeck 1471 * LSCP server:
404     - added support for Windows style path / filenames, however with
405     forward slash path separators instead of backslash
406     (i.e. "C:/foo/bar.gig")
407 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
408     apostrophes as well
409 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
410     "LIST FILE INSTRUMENTS <file>" and
411     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
412     about an arbitrary instrument file on the system where the sampler is
413     running on
414 schoenebeck 1471
415 schoenebeck 1424 Version 0.5.0 (15 October 2007)
416 schoenebeck 947
417 schoenebeck 1065 * packaging changes:
418 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
419     API header files anymore
420 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
421     the Doxygen API documentation (explicitly listed in Doxyfile.in)
422 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
423     capable to execute our autoconf environment, thus no need anymore
424     to maintain the compile time configuration file (osx/version.h) for
425     OSX manually (patch by Toshi Nagata)
426 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
427     parameters
428 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
429     C++ API header files, all implementation internal global definitions
430     are now in global_private.h
431     - atomic.h is not exposed to the C++ API anymore
432     - no need to include config.h anymore for using LS's API header files
433     - fixed warnings in API doc generation
434 schoenebeck 1065
435 schoenebeck 947 * general changes:
436     - replaced the old, confusing MIDI program change mechanism by a
437     flexible MIDI instrument mapper which allows to map arbitrary
438 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
439 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
440     loaded on the respective channel when such MIDI program change
441     messages arrive, beside that, each entry allows to define a life-time
442     strategy for the instrument, so the user can define whether the
443     instrument should i.e. be permanently loaded (to be able to switch
444     quickly among sounds) or i.e. loaded just on demand when the
445     respective program change arrives (to safe RAM space), as well as a
446     global volume factor for each entry, so the user can adjust the volume
447     dynamic of his mapped instrument collection without having to modify
448 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
449     MIDI instrument maps and assign each sampler channel individually
450     a certain map, so that i.e. separation of normal instruments and
451     drumkits is possible
452 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
453     MIDI instrument maps, MIDI instruments, FX sends, global volume.
454 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
455     due to a constant size RingBuffer FIFO which is now replaced by a
456     dynamic (unlimited) size std::list FIFO
457 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
458     output channels for being processed by external effect processors
459     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
460     controllers
461 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
462 iliev 1130 - Implemented new, improved notification system
463 schoenebeck 1149 - fixed compilation errors regarding OSX
464     (patch by Toshi Nagata)
465 iliev 1161 - implemented instruments database
466 iliev 1345 - added support for escape sequences to the instruments database
467 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
468     within the sampler's process (by using instrument editor plugins),
469     you'll notice the new "Registered instrument editors:" message on
470 schoenebeck 1407 startup, added a new LSCP command:
471     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
472 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
473     given sampler channel, the plugin path can be overridden at compile
474     time with ./configure --enable-plugin-dir=/some/dir
475 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
476     in the sampler's process to safely edit instruments while playing
477     without a crash (hopefully) by either suspending single regions
478     wherever possible or if unavoidable whole engine(s)
479 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
480     policy and priority on thread level, set a minimum stack size for
481     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
482     threads simply inherited properties of starting thread instead of
483     setting their own policy and priority
484 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
485     main process did not wait for the stack trace process to finish
486     its output
487 persson 1248 - fixed some minor memory leaks
488 schoenebeck 1259 - reenabled assembly features support, at the moment only for
489     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
490 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
491     register, to avoid relocations in the text segment at runtime)
492 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
493 schoenebeck 947
494     * MIDI driver:
495     - dispatch bank select (MSB and LSB) messages
496    
497 schoenebeck 1049 * audio driver:
498     - the ALSA audio output driver parameters now reflect the correct
499     parameter value ranges for the respective selected sound card
500     (patch by Till Wimmer, a bit fixed and extended)
501    
502 persson 951 * Gigasampler format engine:
503     - if a filter is used and EG2 finishes before EG1, let the voice
504     die when EG2 has finished (this fixes a problem with clicks and
505     voice starvation for some gigs)
506 persson 1038 - playback is no longer disabled during instrument loading
507     - all notes playing on a channel that changes its instrument keep
508     playing with the old instrument until they get a note off
509     command
510 persson 1039 - EG fix: a release value of zero could cause noises or crash
511 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
512 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
513     above max sustain level, which means that there is a decay phase
514     even if sustain is 100%
515 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
516     noises or crashes
517 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
518 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
519     supplied to the configure script (fixes #46)
520 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
521     instead of a fix value
522 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
523     127 (solo mode) only kill voices if the respective mode really
524     changed
525 persson 951
526 schoenebeck 1244 * LSCP server:
527     - fixed compile time error for old Bison versions
528     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
529 schoenebeck 1245 - parser now supports extended ASCII character set
530     (up to ASCII code 255, i.e. includes now umlauts and accents)
531     - filename arguments in LSCP commands now allow to use escape
532     sequences, that is directly literal as one of: \', \", \\, \n, \r,
533     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
534     code value like \xf2) (fixes bug #24)
535 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
536     least one of their text-based parameters (i.e. name, description):
537     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
538     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
539     "SET DB_INSTRUMENT_DIRECTORY NAME",
540     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
541     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
542     "FIND DB_INSTRUMENT_DIRECTORIES"
543 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
544     occured, the unexpected character and the actually expected, possible
545     character(s), the latter only if less than 5 possibilities)
546 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
547     settings
548 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
549     of strings were treated as being one string containing commas
550     (fixes #57)
551 schoenebeck 1244
552 iliev 959 * Bug fixes:
553     - fixed crash occurring on certain LSCP scripts (Bug 39)
554 persson 1038 - another thread safety fix for lscp "load engine" and "set
555     channel audio output device"
556 iliev 1283 - fixed a crash which occurs when reassigning the same engine
557     on a sampler channel with connected MIDI device
558 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
559     device connected to a sampler channel to number less then or equal
560     to the index of the port to which the sampler channel is connected.
561 iliev 1296 - The previous bindings were not been disconnected when altering
562     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
563     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
564 iliev 1297 - The active stream/voice count statistic was incorrect.
565 iliev 1298 - notification events were not been sent for some sampler
566     channel changes
567 iliev 1305 - added default min and max values to restrict the number of allowed
568     audio output channels and MIDI input ports
569 iliev 1306 - the connection to the PCM interface is now closed when destroying
570     an audio output device
571 schoenebeck 1332 - files with slash in their path or filename could not be loaded
572 iliev 959
573 schoenebeck 1221 * test cases:
574     - updated and fixed (haven't been touched in a while)
575    
576 schoenebeck 937 Version 0.4.0 (24 November 2006)
577 persson 696
578 schoenebeck 697 * packaging changes:
579 capela 868 - changed deprecated copyright attribute to license; added ldconfig
580     to post-(un)install steps; added devel package for liblinuxsampler;
581     to linuxsampler.spec (RPM)
582 schoenebeck 697 - install necessary development header files for allowing 3rd party
583     applications to link against liblinuxsampler
584     - liblinuxsampler's API documentation can be generated with 'make docs'
585     (Doxygen required)
586 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
587     implementation (currently either an integer math solution or a
588     di-harmonic approximation), automatic detection can be overriden
589     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
590     configure script argument though (mandatory for cross-compilation)
591 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
592     provided some on his own (as CXXFLAGS)
593 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
594     messages
595 schoenebeck 852 - added compile time options to allow disabling the various audio and
596     MIDI drivers
597 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
598     (patch by Ebrahim Mayat)
599 schoenebeck 697
600 persson 696 * Gigasampler format engine:
601 schoenebeck 738 - extensive synthesis optimization
602     (reimplementation of EGs and LFO(s), removed synthesis parameter
603     prerendering and the synthesis parameter matrix in general, splitting
604     each audio fragment into subfragments now where each subfragment uses
605 persson 830 constant pitch and filter coefficients. The volume coefficient is
606     linearly interpolated inside a subfragment, unless
607     --disable-interpolate-volume is set.)
608 persson 696 - fine tuning of the EG modulation parameters
609 persson 729 - improved filter cutoff calculation by adding support for the
610     following gig parameters: Cutoff freq (used when no cutoff
611     controller is defined), Control invert, Minimum cutoff, Velocity
612 persson 791 curve and Velocity range. The keyboard tracking now scales
613     cutoff frequency instead of resonance.
614 persson 877 - added support for gig parameter Resonance.
615 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
616 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
617     which can be overridden with --enable-global-attenuation
618 persson 783 - EG fixes: made the length of "attack hold" stage more
619     accurate. Release stage can now start before attack stage
620 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
621     time now has a minimal value to prevent clicks.
622 persson 799 - fixed pitch changes larger than one octave
623 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
624     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
625     all modes can be altered via standard GM messages, that is CC5 for
626     altering portamento time, CC65 for enabling / disabling portamento
627     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
628 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
629     parameter) and crossfade
630 persson 831 - added support for the "attenuation controller threshold" gig
631     parameter
632 persson 832 - added smoothing of volume changes caused by control change
633     messages
634 persson 865 - sample loop parameters are now taken from the DimensionRegion
635     instead of the wave chunk
636     - fixed keyswitching for v3 gigs with a number of keyswitch splits
637     not equal to a power of two
638 persson 877 - reimplementation of the filter algorithm. The new filter is more
639     accurate and supports all gig filter types, including bandreject
640     and lowpass turbo.
641 persson 903 - real support for 24 bit samples - samples are not truncated to
642     16 bits anymore
643     - support for aftertouch (channel pressure, not polyphonic
644     aftertouch)
645 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
646     amplifying from 0)
647 persson 696
648 schoenebeck 711 * LSCP server:
649     - fixed application exit on broken pipe error (fixes bug #20)
650 iliev 793 - fixed the notification messages delay due to lack of
651     network activity (fixes bug #26)
652 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
653     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
654 schoenebeck 711
655 schoenebeck 838 * audio driver:
656     - added aRts audio output driver (by no means RT safe)
657    
658 schoenebeck 775 * MIDI driver:
659     - fixed legacy sysex code which caused dispatching of MIDI SysEx
660     messages several times instead of once
661 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
662     for events (i.e. for offline rendering based MIDI drivers)
663 persson 922 - added checks for bad MIDI data
664 schoenebeck 775
665 schoenebeck 900 * linuxsampler application:
666     - show available sampler engine types on startup
667    
668 schoenebeck 705 * general changes:
669     - support for muting sampler channels and solo mode of the same, two new
670     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
671     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
672     introduced for this, the behavior is the same like on a mixer console
673 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
674     --enable-process-muted-channels which can be used to enable the
675     processing of muted channels.
676 iliev 777 - support for sostenuto pedal
677 iliev 779 - support for monitoring the total number of active voices
678 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
679     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
680 persson 835 - fixed some memory management errors
681 persson 841 - fixed some concurrency problems that could lead to crashes when
682     LSCP commands were executed
683 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
684     sampler channel (fixes bug #36)
685 schoenebeck 705
686 schoenebeck 692 Version 0.3.3 (15 July 2005)
687 schoenebeck 686
688     * packaging changes:
689     - fixed compilation with gcc 4.0
690    
691 schoenebeck 687 * Gigasampler format engine:
692     - LFO preprocessing was performed even though the respective LFO was
693     disabled by the instrument patch (minor efficiency fix)
694 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
695     for volume ramp downs in the same fragment (needed for current voice
696     stealing implementation) then simply inform the user with a warning
697     about possible click sounds and reduce the volume ramp down
698     appropriately instead of cancelling the audio device connection
699 schoenebeck 687
700 schoenebeck 677 Version 0.3.2 (24 June 2005)
701 schoenebeck 609
702     * packaging changes:
703     - updated autotools build files to compile on OS X
704     (conditional compilation of CoreMIDI and MidiShare drivers)
705 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
706     './configure --disable-asm' (definitely not recommended)
707 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
708     - require automake (>= 1.5) for 'make -f Makefile.cvs'
709     (due to 'dist-bzip2' automake option)
710 schoenebeck 649
711     * Gigasampler format engine:
712     - support for the gig parameters for "release velocity response" curves
713     - fine tuning of the EGADSR envelope
714     - volume of release triggered samples now depends on note-on velocity,
715     note length and gig parameter "release trigger decay" instead of
716     note-off velocity.
717 schoenebeck 663 - revised voice stealing
718     (fixes crash and endless loop caused by voice stealing)
719 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
720 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
721     instead of when the respective voice is actually launched
722     (fixes undefined behavior if stolen voices belonged to a key group -
723     this case was followed by a "killed voice survived" error message)
724 schoenebeck 669 - fixed minor issue with null/silence samples
725     (those stole voices even though they don't need a voice at all which
726     resulted in "voice stealing didn't work out" messages)
727 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
728     instrument or audio output device change
729 schoenebeck 654
730 schoenebeck 620 * LSCP server:
731 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
732 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
733 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
734 schoenebeck 609
735 schoenebeck 668 * linuxsampler application:
736     - added command line parameters --lscp-addr and --lscp-port to override
737     default IP address and port of LSCP server
738    
739 schoenebeck 579 Version 0.3.1 (24 May 2005)
740    
741     * initial release
