* sfz: added support for sample offset (offset)

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
21
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken
27 - Introduced support for optional environment variable
28 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29 where the sampler shall look for instrument editor plugins
30 (patch by Luis Garrido, slightly modified).
31 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34 note (in this implementation of the sampler its simply hard routed to
35 the 1st effect send of the sampler channel, no matter what the actual
36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to
39 the 2nd effect send of the sampler channel, no matter what the actual
40 effect type is)
41 - implemented support for internal LADSPA effects
42 - raised limit of program change queue from 100 to 512
43 (as suggested by Alex Stone)
44
45 * Gigasampler format engine:
46 - implemented the "round robin keyboard" dimension
47 - fixed round robin and random dimensions for cases when number of
48 dimension zones is not a power of two

50 key
51
52 * SFZ format engine:
53 - Initial implementation (not usable yet)

59 - allow non-numerical key values ("C#4" for example)
60 - "key" opcode now sets pitch_keycenter too
61 - fixed error when unloading instrument with same sample used by
62 multiple regions
63 - added some opcode aliases, like loopmode for loop_mode, to be
64 more compatible

88 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
89 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
90 cutoff_cc, cutoff_chanaft.
91 - bugfix: zero ampeg_sustain didn't work
92 - added support for velocity effect on amplifier envelope time
93 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
94 ampeg_vel2release)

112 * Host plugins:
113 - AU bugfix: failed to destroy its audio/MIDI devices
114 - Listen to all interfaces on Mac OS X (INADDR_ANY)
115 - VST bugfix: If the host called resume() before and after
116 changing sample rate or block size, the number of channels was
117 incorrectly set to two. This caused silence in Cubase 5.
118 - save engine type (gig, sfz or sf2) in plugin state
119 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
120 64 bit Windows
121 - AU: changed number of output channels from one stereo to 16
122 stereo
123 - VST: made it possible to build the VST plugin for Mac
124 - AU: link AU plugin dynamically if --disable-shared isn't
125 specified
126
127 * MIDI driver:
128 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
129 the ALSA sequencer client name
130 - removed limit of maximum amount of MIDI ports per MIDI device, since
131 there is no reason for this limit

169 - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",
170 "SUBSCRIBE EFFECT_INSTANCE_INFO", "SUBSCRIBE SEND_EFFECT_CHAIN_COUNT",
171 "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
172
173 * Bug fixes:
174 - Fixed crash which may occur when MIDI key + transpose is out of range
175 - minor valgrind fixes
176 - fixed crash which occurred when changing an already deployed sampler
177 channel to a different engine type
178 - fixed crash when deleting a sampler channel or changing engine
179 type while an instrument load was in progress
180 - bugfix: playing a note while changing the instrument could cause
181 a crash, or give "Handing back unknown region" error messages
182 - bugfix: calling SET VOICES (which Fantasia does on start and
183 refresh) could cause instruments to be unloaded
184 - Mac OS X: fixed name collision of enum in EffectControl and
185 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
186 - Mac OS X: fixed hanging threads
187 - Windows: disabled the previous thread fix on non-Mac systems, as
188 it caused hanging threads on Windows
189 - Fixed possible crashes due to corrupted MIDI/audio device list
190 after MIDI/audio device creation failure
191
192 Version 1.0.0 (31 July 2009)
193
194 * packaging changes:
195 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
196 causing e.g. the libgig test to fail when
197 "./configure --disable-jack-driver" was used
198 (patch by Alexis Ballier)
199 - fixed compilation with gcc 4.3
200 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
201 - fixed configure so it detects x86_64 (#107)
202 - fixes for building with newer MinGW versions
203 - fix for building with bison 2.4 (#111)
204 - fixed building with libgig installed in a non-standard directory
205 - minor fix in configure for mmsystem.h detection on MinGW
206 - Windows: look for editor plugins and Fantasia using base
207 directory of liblinuxsampler dll (look in the same directory and one
208 directory above)
209 - configure script fix: removed unconditional use of SSE
210 - fixed building with sqlite installed in a non-standard directory
211 - when cross-compiling, don't try to create instruments.db
212 - fix for new mingw-w64 version, which has usleep
213
214 * general changes:
215 - bugfix: on some POSIX systems instrument editor plugins refused to
216 load as we used a non-portable Linux specific struct field
217 (fixes bug #70, patch by Ronald Baljeu)
218 - fixed endless loop which occured when loading an instrument editor
219 plugin DLL on Windows systems failed
220 - fixed memory leaks that occurred when liblinuxsampler was unloaded
221 - optimized the SynchronizedConfig class so it doesn't wait
222 unnecessarily long after an update
223 - added support for notifying instrument editors on note-on / note-off
224 events (e.g. to highlight the pressed keys on the virtual keyboard
225 of gigedit)
226 - added support for triggering notes by instrument editors (see above)
227 - be verbose on DLL load errors (on Linux)
228 - fixed di-harmonic triangle LFO implementation (this LFO implementation
229 is only used by very few systems, most pick the int math
230 implementation, which is usually faster)
231 - fixes for audio drivers with varying buffer sizes
232 - experimental support for running LinuxSampler as a DSSI, LV2 and
233 VST plugin
234 - notification events for stream/voice count statistics are now sent
235 only when there are actual changes
236 - added memory ordering constraints to improve stability on
237 multi-core and multi-cpu systems
238 - maximum voices and disk streams can now be altered at runtime
239 - fixed CPU feature detection on x86_64 (maybe fixes #108)
240 - automatic stacktrace mechanism is now turned off by default and can
241 be switched on by command line option "--stacktrace" (the automatic
242 stacktrace mechanism seems to be broken on most systems at the moment)
243 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
244 a pointer to the launched InstrumentEditor object
245 - added optional 3rd party user data parameter for following
246 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
247 InstrumentEditor::Launch(),
248 InstrumentManager::LaunchInstrumentEditor()
249 - theoretical fix: made SynchronizedConfig follow C++0x memory
250 model more strictly
251 - fixes for using large audio device buffers
252 - Windows: add the installation directory to the DLL search path
253 when loading an editor plugin (solves problems with VST and
254 gigedit on systems with other GTK versions installed)
255
256 * audio driver:
257 - removed the nonsense audio channel constraint (which was hard coded to
258 max. 100 audio channels) for most audio drivers
259 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
260 opposed to the LSCP specs
261 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
262 reflected the wrong value
263 - fixed a memory management bug in ASIO driver
264 - Makefile fix: JACK_CFLAGS wasn't used
265 - JACK: use jack_client_open instead of the deprecated
266 jack_client_new
267 - added (experimental) CoreAudio driver
268 - applied old fixes to the ASIO driver that were included in the
269 previous binary release but accidentally never committed to CVS
270 (fixes #117)
271 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
272 win64)
273 - VST: added support for sample rate and buffer size changes
274 - VST: close editor (Fantasia) when the VST is removed
275 - VST: avoid opening Fantasia more than once for each VST instance
276 - VST: export main function as "main" on Linux too (fix for
277 energyXT)
278 - VST: changed number of output channels from one stereo to 16
279 stereo
280 - added channel routing, fxsends and midi maps to the settings
281 stored in the plugin state
282 - performance optimization of AudioChannel::MixTo() and
283 AudioChannel::CopyTo() methods using GCC vector exensions
284 (if available)
285 - ASIO fixes: avoid initializing the device twice, avoid throwing
286 exception when getting parameters from a disconnected device
287
288 * MIDI driver:
289 - added JACK MIDI driver
290 - dispatch bank select as ordinary CC as well, the user might seriously
291 want to (mis)use it for some purpose ("fixed" in all current MIDI
292 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
293 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
294 CoreMidi or AU
295 - fixed mingw-w64 compilation error in MME driver
296 - made program change handling in MIDI thread real-time safe by
297 moving the logic to a non-RT thread
298 - fixed minor memory leak in ALSA driver
299
300 * instruments database:
301 - avoid time consuming samples scanning when adding instruments
302 to the instruments database
303 - added support for handling lost files in the instruments database
304 - Implemented option for adding instruments in separate directories
305 in the instruments database
306 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
307 - work-around for missing fnmatch function on Windows to make
308 instrument database compilable
309 - added instrument database support on Windows
310 works with both standalone mode and VST plugin.
311 the instruments DB file is located in
312 %USERPROFILE%\.linuxsampler\instruments.db which allows different
313 databases for each windows user
314 if no DB is present it automatically creates the .linuxsampler subdir
315 and then creates an empty DB
316 - fixed recursive import, which was broken on Windows
317
318 * Gigasampler format engine:
319 - fixed a memory leak that could happen when a channel was deleted
320 while notes were playing
321 - made it possible to load an instrument even if the audio thread
322 isn't running
323 - added partial support for the "Controller Triggered" MIDI rule,
324 enough for piano gigs with pedal noise samples
325 - minor fix: only mark FX sends as being modified if really the
326 respective FX send MIDI controller was used
327 - added support for GM global device volume SysEx message
328 (can be selected at compile time to either apply globally to the
329 whole sampler [default] or only to the sampler channels that are
330 connected to the respective MIDI input port the SysEx message arrived
331 on)
332 - bugfix: notes triggered at position 0 in the audio buffer were
333 sometimes wrongly killed in the same buffer, causing no sound to
334 be played
335 - added support for chromatic / drumkit mode Roland GS Sysex message
336 which is usally used to switch a part between chromatic sounds and
337 drumkit sounds (as opposed to their common default setting of MIDI
338 part 10 being a drumkit part and all other ones chromatic parts), in
339 LS however one can switch between the first 16 MIDI instrument maps
340 defined for the sampler
341 - made it possible to create multiple sample channels even if the
342 audio thread isn't running
343 - fixed crash when removing channel with active voices (#116)
344 - bugfix: on sample reference changes (instrument editor), only
345 un-cache the respective sample if it's really not used by any
346 sampler engine anymore
347 - re-cache samples in case they were changed by an instrument editor,
348 e.g. when a sample was added while playing (#82)
349 - fixed hanging notes which occured when note-off event had the exact
350 same time stamp as the voice's note-on event and occured both in the
351 same audio fragment cycle (fixes bug #112)
352 - added support for the "fine tune" and "pitch bend range"
353 instrument-level gig parameters
354 - fixed minor artifacts in pitch bend handling
355 - added support for GS Reset SysEx message
356 - allow gig files to use unlimited downward pitch shifting
357 - added a limit check for upward pitch shifting
358 - bugfix: sometimes, when playing a note twice fast, the second
359 note was silent
360 - fixed crash happening when a pitch bend event arrived at the
361 same time a new instrument was loading
362
363 * LSCP server:
364 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
365 react on MIDI data arriving on certain sampler channels (so far only
366 Note-On and Note-Off events are sent via this LSCP event)
367 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
368 react on MIDI data arriving on certain MIDI input devices (so far only
369 Note-On and Note-Off events are sent via this LSCP event)
370 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
371 SET DB_INSTRUMENT FILE_PATH
372 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
373 frontends to send MIDI messages to specific sampler channel
374 - added two additional fields to GET FILE INSTRUMENT INFO command -
375 KEY_BINDINGS and KEYSWITCH_BINDINGS
376 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
377 was incorrect
378 - Optimized the retrieval of the MIDI instrument mappings
379 - added new LSCP command "SET VOICES" to globally alter the maximum
380 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
381 be triggered respectively
382 - added new LSCP command "SET STREAMS" to globally alter the maximum
383 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
384 which will be triggered respectively
385 - bugfix: retry if "select" returns EINTR (this fixes a crash when
386 a gigedit file dialog is opened)
387 - close all connections when LSCPServer is deleted
388 - hard close of all sockets on exit
389 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
390 driver
391
392 * Bug fixes:
393 - fixed a crash which occurs when removing a sampler channel waiting
394 to start instrument loading after another channel
395 - fixed a crash which occurs when removing a sampler channel with
396 instrument loading in progress (bug #113)
397 - fixed termination caused by uncaught exception when adding MIDI
398 instrument with PERSISTENT load mode
399 - fixed possible iterator invalidations when resetting the sampler
400 - fixed memory leaks when issuing the following LSCP commands:
401 GET AUDIO_OUTPUT_DRIVER INFO
402 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
403 GET MIDI_INPUT_DRIVER INFO
404 GET MIDI_INPUT_DRIVER_PARAMETER INFO
405 - fixed possible compilation error when sqlite is not present
406 - fixed orphaned pointers when setting maximum voices limit (bug #118)
407 - fixed crash when changing the audio output device of a sampler
408 channel with loaded instrument and start playing notes
409 - fixed endless loop in Engine::SuspendAll() (bug #120)
410 - fixed a low-level atomic load function that was broken on 64-bit
411 PowerPC, which probably could cause crashes on that platform
412 - fixed a memory management error which could cause a crash when a
413 plugin was unloaded
414 - bugfix: two private structs had the same name, which could cause
415 problems if the linker chose the wrong constructor
416 - fixed low-level ConditionServer usage bug that caused lockups on
417 Windows
418
419
420 Version 0.5.1 (6 December 2007)
421
422 * packaging changes:
423 - added autoconf checks for pthread library
424 - added autoconf check for pthread bug found on certain NPTL-enabled
425 glibc versions (see Gentoo bug report #194076)
426 - added autoconf checks for MS Windows
427
428 * general changes:
429 - bugfix: the thread used by an editor plugin didn't die when the
430 editor closed
431 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
432 out all the space. operator--() did not apply size_mask after
433 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
434 order to avoid problems with the _NonVolatileReader functions.
435 - bugfix: Stream.h: added a missing divide by BytesPerSample in
436 GetWriteSpace(). Since this function is currently only used in
437 the stream's qsort() compare function, it didn't trigger any
438 bugs.
439 - Resampler.h, Synthesizer.h: cubic interpolation now works in
440 24bit mode too. Faster method to read 24bit words on little
441 endian machines (x86): replaced 3 byte reads + shifts with a 1
442 unaligned 32bit read and shift
443 - experimental support for MS Windows (MIDI input via MME, AUDIO
444 output via ASIO)
445 - made handling of SIGINT signal (Ctrl-C) a bit more robust
446 - support for monitoring the total number of active disk streams
447 (new LSCP commands: GET TOTAL_STREAM_COUNT,
448 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
449
450 * AUDIO driver:
451 - added Windows ASIO low latency audio driver
452
453 * MIDI driver:
454 - added MME Windows MIDI driver
455
456 * LSCP server:
457 - added support for Windows style path / filenames, however with
458 forward slash path separators instead of backslash
459 (i.e. "C:/foo/bar.gig")
460 - allow naughty liblscp to send non-string device parameters within
461 apostrophes as well
462 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
463 "LIST FILE INSTRUMENTS <file>" and
464 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
465 about an arbitrary instrument file on the system where the sampler is
466 running on
467
468 Version 0.5.0 (15 October 2007)
469
470 * packaging changes:
471 - config.h is not going to be installed along with liblinuxsampler's
472 API header files anymore
473 - only the API relevant header (and source) files will be exported to
474 the Doxygen API documentation (explicitly listed in Doxyfile.in)
475 - added completely new XCode project files for Mac OSX which is now
476 capable to execute our autoconf environment, thus no need anymore
477 to maintain the compile time configuration file (osx/version.h) for
478 OSX manually (patch by Toshi Nagata)
479 - fixed buggy boolean --enable-foo / --disable-foo configure script
480 parameters
481 - global.h now only covers global definitions that are needed for the
482 C++ API header files, all implementation internal global definitions
483 are now in global_private.h
484 - atomic.h is not exposed to the C++ API anymore
485 - no need to include config.h anymore for using LS's API header files
486 - fixed warnings in API doc generation
487
488 * general changes:
489 - replaced the old, confusing MIDI program change mechanism by a
490 flexible MIDI instrument mapper which allows to map arbitrary
491 (MIDI bank, MIDI program) pairs with arbitrary
492 (engine type, instrument file, file index) triplets which will be
493 loaded on the respective channel when such MIDI program change
494 messages arrive, beside that, each entry allows to define a life-time
495 strategy for the instrument, so the user can define whether the
496 instrument should i.e. be permanently loaded (to be able to switch
497 quickly among sounds) or i.e. loaded just on demand when the
498 respective program change arrives (to safe RAM space), as well as a
499 global volume factor for each entry, so the user can adjust the volume
500 dynamic of his mapped instrument collection without having to modify
501 the instrument files, also one can manage arbitrary amount of such
502 MIDI instrument maps and assign each sampler channel individually
503 a certain map, so that i.e. separation of normal instruments and
504 drumkits is possible
505 - new notification events for tracking changes to audio/MIDI devices,
506 MIDI instrument maps, MIDI instruments, FX sends, global volume.
507 - sampler was limited to load max. 200 instruments in the background
508 due to a constant size RingBuffer FIFO which is now replaced by a
509 dynamic (unlimited) size std::list FIFO
510 - added FX sends, these allow to route audio signals to arbitrary audio
511 output channels for being processed by external effect processors
512 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
513 controllers
514 - global (sampler wide) volume can now be controlled at runtime
515 - Implemented new, improved notification system
516 - fixed compilation errors regarding OSX
517 (patch by Toshi Nagata)
518 - implemented instruments database
519 - added support for escape sequences to the instruments database
520 - added highly experimental support for on-the-fly instrument editing
521 within the sampler's process (by using instrument editor plugins),
522 you'll notice the new "Registered instrument editors:" message on
523 startup, added a new LSCP command:
524 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
525 to spawn a matching instrument editor for the instrument on the
526 given sampler channel, the plugin path can be overridden at compile
527 time with ./configure --enable-plugin-dir=/some/dir
528 - added experimental code for synchronizing instrument editors hosted
529 in the sampler's process to safely edit instruments while playing
530 without a crash (hopefully) by either suspending single regions
531 wherever possible or if unavoidable whole engine(s)
532 - fixed several issues in fundamental "Thread" class: set scheduling
533 policy and priority on thread level, set a minimum stack size for
534 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
535 threads simply inherited properties of starting thread instead of
536 setting their own policy and priority
537 - minor fix in our automatic stack trace mechanism on crashes, the
538 main process did not wait for the stack trace process to finish
539 its output
540 - fixed some minor memory leaks
541 - reenabled assembly features support, at the moment only for
542 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
543 - minor assembly fix in x86 features detection (don't use the PIC
544 register, to avoid relocations in the text segment at runtime)
545 - POSIX callback functions of Thread.h are hidden
546
547 * MIDI driver:
548 - dispatch bank select (MSB and LSB) messages
549
550 * audio driver:
551 - the ALSA audio output driver parameters now reflect the correct
552 parameter value ranges for the respective selected sound card
553 (patch by Till Wimmer, a bit fixed and extended)
554
555 * Gigasampler format engine:
556 - if a filter is used and EG2 finishes before EG1, let the voice
557 die when EG2 has finished (this fixes a problem with clicks and
558 voice starvation for some gigs)
559 - playback is no longer disabled during instrument loading
560 - all notes playing on a channel that changes its instrument keep
561 playing with the old instrument until they get a note off
562 command
563 - EG fix: a release value of zero could cause noises or crash
564 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
565 - EG fine tuning: when attack is zero the EG starts at a level
566 above max sustain level, which means that there is a decay phase
567 even if sustain is 100%
568 - more EG fixes: the level could sometimes go below zero and cause
569 noises or crashes
570 - minor fix of EGDecay (patch by Toshi Nagata)
571 - fixed compiler error when --enable-override-filter-type was
572 supplied to the configure script (fixes #46)
573 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
574 instead of a fix value
575 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
576 127 (solo mode) only kill voices if the respective mode really
577 changed
578
579 * LSCP server:
580 - fixed compile time error for old Bison versions
581 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
582 - parser now supports extended ASCII character set
583 (up to ASCII code 255, i.e. includes now umlauts and accents)
584 - filename arguments in LSCP commands now allow to use escape
585 sequences, that is directly literal as one of: \', \", \\, \n, \r,
586 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
587 code value like \xf2) (fixes bug #24)
588 - the following LSCP commands now also support escape sequences for at
589 least one of their text-based parameters (i.e. name, description):
590 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
591 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
592 "SET DB_INSTRUMENT_DIRECTORY NAME",
593 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
594 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
595 "FIND DB_INSTRUMENT_DIRECTORIES"
596 - returns verbose syntax errors (line and column where syntax error
597 occured, the unexpected character and the actually expected, possible
598 character(s), the latter only if less than 5 possibilities)
599 - made sure that LSCP syntax is not affected by gigedit locale
600 settings
601 - bugfix regarding strings parameter lists: all comma separated lists
602 of strings were treated as being one string containing commas
603 (fixes #57)
604
605 * Bug fixes:
606 - fixed crash occurring on certain LSCP scripts (Bug 39)
607 - another thread safety fix for lscp "load engine" and "set
608 channel audio output device"
609 - fixed a crash which occurs when reassigning the same engine
610 on a sampler channel with connected MIDI device
611 - fixed a crash which occurs when changing the number of ports of a MIDI
612 device connected to a sampler channel to number less then or equal
613 to the index of the port to which the sampler channel is connected.
614 - The previous bindings were not been disconnected when altering
615 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
616 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
617 - The active stream/voice count statistic was incorrect.
618 - notification events were not been sent for some sampler
619 channel changes
620 - added default min and max values to restrict the number of allowed
621 audio output channels and MIDI input ports
622 - the connection to the PCM interface is now closed when destroying
623 an audio output device
624 - files with slash in their path or filename could not be loaded
625
626 * test cases:
627 - updated and fixed (haven't been touched in a while)
628
629 Version 0.4.0 (24 November 2006)
630
631 * packaging changes:
632 - changed deprecated copyright attribute to license; added ldconfig
633 to post-(un)install steps; added devel package for liblinuxsampler;
634 to linuxsampler.spec (RPM)
635 - install necessary development header files for allowing 3rd party
636 applications to link against liblinuxsampler
637 - liblinuxsampler's API documentation can be generated with 'make docs'
638 (Doxygen required)
639 - added benchmark to automatically detect the best triangle LFO
640 implementation (currently either an integer math solution or a
641 di-harmonic approximation), automatic detection can be overriden
642 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
643 configure script argument though (mandatory for cross-compilation)
644 - do not automatically pick optimized gcc flags if the user already
645 provided some on his own (as CXXFLAGS)
646 - added compile time option to disable processing of All-Notes-Off MIDI
647 messages
648 - added compile time options to allow disabling the various audio and
649 MIDI drivers
650 - fixed automatic GCC CPU switch detection on PPC
651 (patch by Ebrahim Mayat)
652
653 * Gigasampler format engine:
654 - extensive synthesis optimization
655 (reimplementation of EGs and LFO(s), removed synthesis parameter
656 prerendering and the synthesis parameter matrix in general, splitting
657 each audio fragment into subfragments now where each subfragment uses
658 constant pitch and filter coefficients. The volume coefficient is
659 linearly interpolated inside a subfragment, unless
660 --disable-interpolate-volume is set.)
661 - fine tuning of the EG modulation parameters
662 - improved filter cutoff calculation by adding support for the
663 following gig parameters: Cutoff freq (used when no cutoff
664 controller is defined), Control invert, Minimum cutoff, Velocity
665 curve and Velocity range. The keyboard tracking now scales
666 cutoff frequency instead of resonance.
667 - added support for gig parameter Resonance.
668 - fixed bug in sysex handling (patch by Juan Linietsky)
669 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
670 which can be overridden with --enable-global-attenuation
671 - EG fixes: made the length of "attack hold" stage more
672 accurate. Release stage can now start before attack stage
673 ends. Cancel release didn't work when sustain was zero. Attack
674 time now has a minimal value to prevent clicks.
675 - fixed pitch changes larger than one octave
676 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
677 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
678 all modes can be altered via standard GM messages, that is CC5 for
679 altering portamento time, CC65 for enabling / disabling portamento
680 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
681 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
682 parameter) and crossfade
683 - added support for the "attenuation controller threshold" gig
684 parameter
685 - added smoothing of volume changes caused by control change
686 messages
687 - sample loop parameters are now taken from the DimensionRegion
688 instead of the wave chunk
689 - fixed keyswitching for v3 gigs with a number of keyswitch splits
690 not equal to a power of two
691 - reimplementation of the filter algorithm. The new filter is more
692 accurate and supports all gig filter types, including bandreject
693 and lowpass turbo.
694 - real support for 24 bit samples - samples are not truncated to
695 16 bits anymore
696 - support for aftertouch (channel pressure, not polyphonic
697 aftertouch)
698 - LFO1 behaviour fixed (dampening from max volume instead of
699 amplifying from 0)
700
701 * LSCP server:
702 - fixed application exit on broken pipe error (fixes bug #20)
703 - fixed the notification messages delay due to lack of
704 network activity (fixes bug #26)
705 - fixed parser bug which occured on space(s) within device parameters
706 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
707
708 * audio driver:
709 - added aRts audio output driver (by no means RT safe)
710
711 * MIDI driver:
712 - fixed legacy sysex code which caused dispatching of MIDI SysEx
713 messages several times instead of once
714 - API extension for MIDI drivers which already supply exact time stamps
715 for events (i.e. for offline rendering based MIDI drivers)
716 - added checks for bad MIDI data
717
718 * linuxsampler application:
719 - show available sampler engine types on startup
720
721 * general changes:
722 - support for muting sampler channels and solo mode of the same, two new
723 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
724 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
725 introduced for this, the behavior is the same like on a mixer console
726 (patch by Grigor Iliev, a bit adjusted). Also added configure option
727 --enable-process-muted-channels which can be used to enable the
728 processing of muted channels.
729 - support for sostenuto pedal
730 - support for monitoring the total number of active voices
731 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
732 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
733 - fixed some memory management errors
734 - fixed some concurrency problems that could lead to crashes when
735 LSCP commands were executed
736 - fixed crash when instrument loading failed previously on the same
737 sampler channel (fixes bug #36)
738
739 Version 0.3.3 (15 July 2005)
740
741 * packaging changes:
742 - fixed compilation with gcc 4.0
743
744 * Gigasampler format engine:
745 - LFO preprocessing was performed even though the respective LFO was
746 disabled by the instrument patch (minor efficiency fix)
747 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
748 for volume ramp downs in the same fragment (needed for current voice
749 stealing implementation) then simply inform the user with a warning
750 about possible click sounds and reduce the volume ramp down
751 appropriately instead of cancelling the audio device connection
752
753 Version 0.3.2 (24 June 2005)
754
755 * packaging changes:
756 - updated autotools build files to compile on OS X
757 (conditional compilation of CoreMIDI and MidiShare drivers)
758 - hand-crafted assembly optimization code can be disabled with
759 './configure --disable-asm' (definitely not recommended)
760 - fixed 'make dist' rule to include all necessary files
761 - require automake (>= 1.5) for 'make -f Makefile.cvs'
762 (due to 'dist-bzip2' automake option)
763
764 * Gigasampler format engine:
765 - support for the gig parameters for "release velocity response" curves
766 - fine tuning of the EGADSR envelope
767 - volume of release triggered samples now depends on note-on velocity,
768 note length and gig parameter "release trigger decay" instead of
769 note-off velocity.
770 - revised voice stealing
771 (fixes crash and endless loop caused by voice stealing)
772 - don't reset scale tuning on instrument or audio output device change
773 - handle key group conflicts right at the beginning of each fragment
774 instead of when the respective voice is actually launched
775 (fixes undefined behavior if stolen voices belonged to a key group -
776 this case was followed by a "killed voice survived" error message)
777 - fixed minor issue with null/silence samples
778 (those stole voices even though they don't need a voice at all which
779 resulted in "voice stealing didn't work out" messages)
780 - don't reset volume, pan, pitch and MIDI controller values on
781 instrument or audio output device change
782
783 * LSCP server:
784 - fixed some crashes (patch by Grigor Iliev, fixes #19)
785 - fixed LSCP event "CHANNEL_INFO" notification
786 (e.g. did not notify on volume changes or MIDI program change events)
787
788 * linuxsampler application:
789 - added command line parameters --lscp-addr and --lscp-port to override
790 default IP address and port of LSCP server
791
792 Version 0.3.1 (24 May 2005)
793
794 * initial release
