* sfz engine: implemented opcodes volume_onccN, volume_curveccN

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)

158 * MIDI driver:
159 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
160 the ALSA sequencer client name

206 - minor valgrind fixes
207 - fixed crash which occurred when changing an already deployed sampler
208 channel to a different engine type
209 - fixed crash when deleting a sampler channel or changing engine
210 type while an instrument load was in progress
211 - bugfix: playing a note while changing the instrument could cause
212 a crash, or give "Handing back unknown region" error messages
213 - bugfix: calling SET VOICES (which Fantasia does on start and
214 refresh) could cause instruments to be unloaded
215 - Mac OS X: fixed name collision of enum in EffectControl and

222
223 Version 1.0.0 (31 July 2009)
224
225 * packaging changes:
226 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
227 causing e.g. the libgig test to fail when
228 "./configure --disable-jack-driver" was used
229 (patch by Alexis Ballier)
230 - fixed compilation with gcc 4.3
231 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
232 - fixed configure so it detects x86_64 (#107)
233 - fixes for building with newer MinGW versions
234 - fix for building with bison 2.4 (#111)
235 - fixed building with libgig installed in a non-standard directory
236 - minor fix in configure for mmsystem.h detection on MinGW
237 - Windows: look for editor plugins and Fantasia using base
238 directory of liblinuxsampler dll (look in the same directory and one
239 directory above)
240 - configure script fix: removed unconditional use of SSE
241 - fixed building with sqlite installed in a non-standard directory
242 - when cross-compiling, don't try to create instruments.db
243 - fix for new mingw-w64 version, which has usleep
244
245 * general changes:
246 - bugfix: on some POSIX systems instrument editor plugins refused to
247 load as we used a non-portable Linux specific struct field
248 (fixes bug #70, patch by Ronald Baljeu)
249 - fixed endless loop which occured when loading an instrument editor
250 plugin DLL on Windows systems failed
251 - fixed memory leaks that occurred when liblinuxsampler was unloaded
252 - optimized the SynchronizedConfig class so it doesn't wait
253 unnecessarily long after an update
254 - added support for notifying instrument editors on note-on / note-off
255 events (e.g. to highlight the pressed keys on the virtual keyboard
256 of gigedit)
257 - added support for triggering notes by instrument editors (see above)
258 - be verbose on DLL load errors (on Linux)
259 - fixed di-harmonic triangle LFO implementation (this LFO implementation
260 is only used by very few systems, most pick the int math
261 implementation, which is usually faster)
262 - fixes for audio drivers with varying buffer sizes
263 - experimental support for running LinuxSampler as a DSSI, LV2 and
264 VST plugin
265 - notification events for stream/voice count statistics are now sent
266 only when there are actual changes
267 - added memory ordering constraints to improve stability on
268 multi-core and multi-cpu systems
269 - maximum voices and disk streams can now be altered at runtime
270 - fixed CPU feature detection on x86_64 (maybe fixes #108)
271 - automatic stacktrace mechanism is now turned off by default and can
272 be switched on by command line option "--stacktrace" (the automatic
273 stacktrace mechanism seems to be broken on most systems at the moment)
274 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
275 a pointer to the launched InstrumentEditor object
276 - added optional 3rd party user data parameter for following
277 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
278 InstrumentEditor::Launch(),
279 InstrumentManager::LaunchInstrumentEditor()
280 - theoretical fix: made SynchronizedConfig follow C++0x memory
281 model more strictly
282 - fixes for using large audio device buffers
283 - Windows: add the installation directory to the DLL search path
284 when loading an editor plugin (solves problems with VST and
285 gigedit on systems with other GTK versions installed)
286
287 * audio driver:
288 - removed the nonsense audio channel constraint (which was hard coded to
289 max. 100 audio channels) for most audio drivers
290 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
291 opposed to the LSCP specs
292 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
293 reflected the wrong value
294 - fixed a memory management bug in ASIO driver
295 - Makefile fix: JACK_CFLAGS wasn't used
296 - JACK: use jack_client_open instead of the deprecated
297 jack_client_new
298 - added (experimental) CoreAudio driver
299 - applied old fixes to the ASIO driver that were included in the
300 previous binary release but accidentally never committed to CVS
301 (fixes #117)
302 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
303 win64)
304 - VST: added support for sample rate and buffer size changes
305 - VST: close editor (Fantasia) when the VST is removed
306 - VST: avoid opening Fantasia more than once for each VST instance
307 - VST: export main function as "main" on Linux too (fix for
308 energyXT)
309 - VST: changed number of output channels from one stereo to 16
310 stereo
311 - added channel routing, fxsends and midi maps to the settings
312 stored in the plugin state
313 - performance optimization of AudioChannel::MixTo() and
314 AudioChannel::CopyTo() methods using GCC vector exensions
315 (if available)
316 - ASIO fixes: avoid initializing the device twice, avoid throwing
317 exception when getting parameters from a disconnected device
318
319 * MIDI driver:
320 - added JACK MIDI driver
321 - dispatch bank select as ordinary CC as well, the user might seriously
322 want to (mis)use it for some purpose ("fixed" in all current MIDI
323 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
324 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
325 CoreMidi or AU
326 - fixed mingw-w64 compilation error in MME driver
327 - made program change handling in MIDI thread real-time safe by
328 moving the logic to a non-RT thread
329 - fixed minor memory leak in ALSA driver
330
331 * instruments database:
332 - avoid time consuming samples scanning when adding instruments
333 to the instruments database
334 - added support for handling lost files in the instruments database
335 - Implemented option for adding instruments in separate directories
336 in the instruments database
337 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
338 - work-around for missing fnmatch function on Windows to make
339 instrument database compilable
340 - added instrument database support on Windows
341 works with both standalone mode and VST plugin.
342 the instruments DB file is located in
343 %USERPROFILE%\.linuxsampler\instruments.db which allows different
344 databases for each windows user
345 if no DB is present it automatically creates the .linuxsampler subdir
346 and then creates an empty DB
347 - fixed recursive import, which was broken on Windows
348
349 * Gigasampler format engine:
350 - fixed a memory leak that could happen when a channel was deleted
351 while notes were playing
352 - made it possible to load an instrument even if the audio thread
353 isn't running
354 - added partial support for the "Controller Triggered" MIDI rule,
355 enough for piano gigs with pedal noise samples
356 - minor fix: only mark FX sends as being modified if really the
357 respective FX send MIDI controller was used
358 - added support for GM global device volume SysEx message
359 (can be selected at compile time to either apply globally to the
360 whole sampler [default] or only to the sampler channels that are
361 connected to the respective MIDI input port the SysEx message arrived
362 on)
363 - bugfix: notes triggered at position 0 in the audio buffer were
364 sometimes wrongly killed in the same buffer, causing no sound to
365 be played
366 - added support for chromatic / drumkit mode Roland GS Sysex message
367 which is usally used to switch a part between chromatic sounds and
368 drumkit sounds (as opposed to their common default setting of MIDI
369 part 10 being a drumkit part and all other ones chromatic parts), in
370 LS however one can switch between the first 16 MIDI instrument maps
371 defined for the sampler
372 - made it possible to create multiple sample channels even if the
373 audio thread isn't running
374 - fixed crash when removing channel with active voices (#116)
375 - bugfix: on sample reference changes (instrument editor), only
376 un-cache the respective sample if it's really not used by any
377 sampler engine anymore
378 - re-cache samples in case they were changed by an instrument editor,
379 e.g. when a sample was added while playing (#82)
380 - fixed hanging notes which occured when note-off event had the exact
381 same time stamp as the voice's note-on event and occured both in the
382 same audio fragment cycle (fixes bug #112)
383 - added support for the "fine tune" and "pitch bend range"
384 instrument-level gig parameters
385 - fixed minor artifacts in pitch bend handling
386 - added support for GS Reset SysEx message
387 - allow gig files to use unlimited downward pitch shifting
388 - added a limit check for upward pitch shifting
389 - bugfix: sometimes, when playing a note twice fast, the second
390 note was silent
391 - fixed crash happening when a pitch bend event arrived at the
392 same time a new instrument was loading
393
394 * LSCP server:
395 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
396 react on MIDI data arriving on certain sampler channels (so far only
397 Note-On and Note-Off events are sent via this LSCP event)
398 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
399 react on MIDI data arriving on certain MIDI input devices (so far only
400 Note-On and Note-Off events are sent via this LSCP event)
401 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
402 SET DB_INSTRUMENT FILE_PATH
403 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
404 frontends to send MIDI messages to specific sampler channel
405 - added two additional fields to GET FILE INSTRUMENT INFO command -
406 KEY_BINDINGS and KEYSWITCH_BINDINGS
407 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
408 was incorrect
409 - Optimized the retrieval of the MIDI instrument mappings
410 - added new LSCP command "SET VOICES" to globally alter the maximum
411 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
412 be triggered respectively
413 - added new LSCP command "SET STREAMS" to globally alter the maximum
414 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
415 which will be triggered respectively
416 - bugfix: retry if "select" returns EINTR (this fixes a crash when
417 a gigedit file dialog is opened)
418 - close all connections when LSCPServer is deleted
419 - hard close of all sockets on exit
420 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
421 driver
422
423 * Bug fixes:
424 - fixed a crash which occurs when removing a sampler channel waiting
425 to start instrument loading after another channel
426 - fixed a crash which occurs when removing a sampler channel with
427 instrument loading in progress (bug #113)
428 - fixed termination caused by uncaught exception when adding MIDI
429 instrument with PERSISTENT load mode
430 - fixed possible iterator invalidations when resetting the sampler
431 - fixed memory leaks when issuing the following LSCP commands:
432 GET AUDIO_OUTPUT_DRIVER INFO
433 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
434 GET MIDI_INPUT_DRIVER INFO
435 GET MIDI_INPUT_DRIVER_PARAMETER INFO
436 - fixed possible compilation error when sqlite is not present
437 - fixed orphaned pointers when setting maximum voices limit (bug #118)
438 - fixed crash when changing the audio output device of a sampler
439 channel with loaded instrument and start playing notes
440 - fixed endless loop in Engine::SuspendAll() (bug #120)
441 - fixed a low-level atomic load function that was broken on 64-bit
442 PowerPC, which probably could cause crashes on that platform
443 - fixed a memory management error which could cause a crash when a
444 plugin was unloaded
445 - bugfix: two private structs had the same name, which could cause
446 problems if the linker chose the wrong constructor
447 - fixed low-level ConditionServer usage bug that caused lockups on
448 Windows
449
450
451 Version 0.5.1 (6 December 2007)
452
453 * packaging changes:
454 - added autoconf checks for pthread library
455 - added autoconf check for pthread bug found on certain NPTL-enabled
456 glibc versions (see Gentoo bug report #194076)
457 - added autoconf checks for MS Windows
458
459 * general changes:
460 - bugfix: the thread used by an editor plugin didn't die when the
461 editor closed
462 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
463 out all the space. operator--() did not apply size_mask after
464 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
465 order to avoid problems with the _NonVolatileReader functions.
466 - bugfix: Stream.h: added a missing divide by BytesPerSample in
467 GetWriteSpace(). Since this function is currently only used in
468 the stream's qsort() compare function, it didn't trigger any
469 bugs.
470 - Resampler.h, Synthesizer.h: cubic interpolation now works in
471 24bit mode too. Faster method to read 24bit words on little
472 endian machines (x86): replaced 3 byte reads + shifts with a 1
473 unaligned 32bit read and shift
474 - experimental support for MS Windows (MIDI input via MME, AUDIO
475 output via ASIO)
476 - made handling of SIGINT signal (Ctrl-C) a bit more robust
477 - support for monitoring the total number of active disk streams
478 (new LSCP commands: GET TOTAL_STREAM_COUNT,
479 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
480
481 * AUDIO driver:
482 - added Windows ASIO low latency audio driver
483
484 * MIDI driver:
485 - added MME Windows MIDI driver
486
487 * LSCP server:
488 - added support for Windows style path / filenames, however with
489 forward slash path separators instead of backslash
490 (i.e. "C:/foo/bar.gig")
491 - allow naughty liblscp to send non-string device parameters within
492 apostrophes as well
493 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
494 "LIST FILE INSTRUMENTS <file>" and
495 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
496 about an arbitrary instrument file on the system where the sampler is
497 running on
498
499 Version 0.5.0 (15 October 2007)
500
501 * packaging changes:
502 - config.h is not going to be installed along with liblinuxsampler's
503 API header files anymore
504 - only the API relevant header (and source) files will be exported to
505 the Doxygen API documentation (explicitly listed in Doxyfile.in)
506 - added completely new XCode project files for Mac OSX which is now
507 capable to execute our autoconf environment, thus no need anymore
508 to maintain the compile time configuration file (osx/version.h) for
509 OSX manually (patch by Toshi Nagata)
510 - fixed buggy boolean --enable-foo / --disable-foo configure script
511 parameters
512 - global.h now only covers global definitions that are needed for the
513 C++ API header files, all implementation internal global definitions
514 are now in global_private.h
515 - atomic.h is not exposed to the C++ API anymore
516 - no need to include config.h anymore for using LS's API header files
517 - fixed warnings in API doc generation
518
519 * general changes:
520 - replaced the old, confusing MIDI program change mechanism by a
521 flexible MIDI instrument mapper which allows to map arbitrary
522 (MIDI bank, MIDI program) pairs with arbitrary
523 (engine type, instrument file, file index) triplets which will be
524 loaded on the respective channel when such MIDI program change
525 messages arrive, beside that, each entry allows to define a life-time
526 strategy for the instrument, so the user can define whether the
527 instrument should i.e. be permanently loaded (to be able to switch
528 quickly among sounds) or i.e. loaded just on demand when the
529 respective program change arrives (to safe RAM space), as well as a
530 global volume factor for each entry, so the user can adjust the volume
531 dynamic of his mapped instrument collection without having to modify
532 the instrument files, also one can manage arbitrary amount of such
533 MIDI instrument maps and assign each sampler channel individually
534 a certain map, so that i.e. separation of normal instruments and
535 drumkits is possible
536 - new notification events for tracking changes to audio/MIDI devices,
537 MIDI instrument maps, MIDI instruments, FX sends, global volume.
538 - sampler was limited to load max. 200 instruments in the background
539 due to a constant size RingBuffer FIFO which is now replaced by a
540 dynamic (unlimited) size std::list FIFO
541 - added FX sends, these allow to route audio signals to arbitrary audio
542 output channels for being processed by external effect processors
543 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
544 controllers
545 - global (sampler wide) volume can now be controlled at runtime
546 - Implemented new, improved notification system
547 - fixed compilation errors regarding OSX
548 (patch by Toshi Nagata)
549 - implemented instruments database
550 - added support for escape sequences to the instruments database
551 - added highly experimental support for on-the-fly instrument editing
552 within the sampler's process (by using instrument editor plugins),
553 you'll notice the new "Registered instrument editors:" message on
554 startup, added a new LSCP command:
555 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
556 to spawn a matching instrument editor for the instrument on the
557 given sampler channel, the plugin path can be overridden at compile
558 time with ./configure --enable-plugin-dir=/some/dir
559 - added experimental code for synchronizing instrument editors hosted
560 in the sampler's process to safely edit instruments while playing
561 without a crash (hopefully) by either suspending single regions
562 wherever possible or if unavoidable whole engine(s)
563 - fixed several issues in fundamental "Thread" class: set scheduling
564 policy and priority on thread level, set a minimum stack size for
565 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
566 threads simply inherited properties of starting thread instead of
567 setting their own policy and priority
568 - minor fix in our automatic stack trace mechanism on crashes, the
569 main process did not wait for the stack trace process to finish
570 its output
571 - fixed some minor memory leaks
572 - reenabled assembly features support, at the moment only for
573 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
574 - minor assembly fix in x86 features detection (don't use the PIC
575 register, to avoid relocations in the text segment at runtime)
576 - POSIX callback functions of Thread.h are hidden
577
578 * MIDI driver:
579 - dispatch bank select (MSB and LSB) messages
580
581 * audio driver:
582 - the ALSA audio output driver parameters now reflect the correct
583 parameter value ranges for the respective selected sound card
584 (patch by Till Wimmer, a bit fixed and extended)
585
586 * Gigasampler format engine:
587 - if a filter is used and EG2 finishes before EG1, let the voice
588 die when EG2 has finished (this fixes a problem with clicks and
589 voice starvation for some gigs)
590 - playback is no longer disabled during instrument loading
591 - all notes playing on a channel that changes its instrument keep
592 playing with the old instrument until they get a note off
593 command
594 - EG fix: a release value of zero could cause noises or crash
595 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
596 - EG fine tuning: when attack is zero the EG starts at a level
597 above max sustain level, which means that there is a decay phase
598 even if sustain is 100%
599 - more EG fixes: the level could sometimes go below zero and cause
600 noises or crashes
601 - minor fix of EGDecay (patch by Toshi Nagata)
602 - fixed compiler error when --enable-override-filter-type was
603 supplied to the configure script (fixes #46)
604 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
605 instead of a fix value
606 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
607 127 (solo mode) only kill voices if the respective mode really
608 changed
609
610 * LSCP server:
611 - fixed compile time error for old Bison versions
612 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
613 - parser now supports extended ASCII character set
614 (up to ASCII code 255, i.e. includes now umlauts and accents)
615 - filename arguments in LSCP commands now allow to use escape
616 sequences, that is directly literal as one of: \', \", \\, \n, \r,
617 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
618 code value like \xf2) (fixes bug #24)
619 - the following LSCP commands now also support escape sequences for at
620 least one of their text-based parameters (i.e. name, description):
621 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
622 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
623 "SET DB_INSTRUMENT_DIRECTORY NAME",
624 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
625 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
626 "FIND DB_INSTRUMENT_DIRECTORIES"
627 - returns verbose syntax errors (line and column where syntax error
628 occured, the unexpected character and the actually expected, possible
629 character(s), the latter only if less than 5 possibilities)
630 - made sure that LSCP syntax is not affected by gigedit locale
631 settings
632 - bugfix regarding strings parameter lists: all comma separated lists
633 of strings were treated as being one string containing commas
634 (fixes #57)
635
636 * Bug fixes:
637 - fixed crash occurring on certain LSCP scripts (Bug 39)
638 - another thread safety fix for lscp "load engine" and "set
639 channel audio output device"
640 - fixed a crash which occurs when reassigning the same engine
641 on a sampler channel with connected MIDI device
642 - fixed a crash which occurs when changing the number of ports of a MIDI
643 device connected to a sampler channel to number less then or equal
644 to the index of the port to which the sampler channel is connected.
645 - The previous bindings were not been disconnected when altering
646 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
647 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
648 - The active stream/voice count statistic was incorrect.
649 - notification events were not been sent for some sampler
650 channel changes
651 - added default min and max values to restrict the number of allowed
652 audio output channels and MIDI input ports
653 - the connection to the PCM interface is now closed when destroying
654 an audio output device
655 - files with slash in their path or filename could not be loaded
656
657 * test cases:
658 - updated and fixed (haven't been touched in a while)
659
660 Version 0.4.0 (24 November 2006)
661
662 * packaging changes:
663 - changed deprecated copyright attribute to license; added ldconfig
664 to post-(un)install steps; added devel package for liblinuxsampler;
665 to linuxsampler.spec (RPM)
666 - install necessary development header files for allowing 3rd party
667 applications to link against liblinuxsampler
668 - liblinuxsampler's API documentation can be generated with 'make docs'
669 (Doxygen required)
670 - added benchmark to automatically detect the best triangle LFO
671 implementation (currently either an integer math solution or a
672 di-harmonic approximation), automatic detection can be overriden
673 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
674 configure script argument though (mandatory for cross-compilation)
675 - do not automatically pick optimized gcc flags if the user already
676 provided some on his own (as CXXFLAGS)
677 - added compile time option to disable processing of All-Notes-Off MIDI
678 messages
679 - added compile time options to allow disabling the various audio and
680 MIDI drivers
681 - fixed automatic GCC CPU switch detection on PPC
682 (patch by Ebrahim Mayat)
683
684 * Gigasampler format engine:
685 - extensive synthesis optimization
686 (reimplementation of EGs and LFO(s), removed synthesis parameter
687 prerendering and the synthesis parameter matrix in general, splitting
688 each audio fragment into subfragments now where each subfragment uses
689 constant pitch and filter coefficients. The volume coefficient is
690 linearly interpolated inside a subfragment, unless
691 --disable-interpolate-volume is set.)
692 - fine tuning of the EG modulation parameters
693 - improved filter cutoff calculation by adding support for the
694 following gig parameters: Cutoff freq (used when no cutoff
695 controller is defined), Control invert, Minimum cutoff, Velocity
696 curve and Velocity range. The keyboard tracking now scales
697 cutoff frequency instead of resonance.
698 - added support for gig parameter Resonance.
699 - fixed bug in sysex handling (patch by Juan Linietsky)
700 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
701 which can be overridden with --enable-global-attenuation
702 - EG fixes: made the length of "attack hold" stage more
703 accurate. Release stage can now start before attack stage
704 ends. Cancel release didn't work when sustain was zero. Attack
705 time now has a minimal value to prevent clicks.
706 - fixed pitch changes larger than one octave
707 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
708 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
709 all modes can be altered via standard GM messages, that is CC5 for
710 altering portamento time, CC65 for enabling / disabling portamento
711 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
712 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
713 parameter) and crossfade
714 - added support for the "attenuation controller threshold" gig
715 parameter
716 - added smoothing of volume changes caused by control change
717 messages
718 - sample loop parameters are now taken from the DimensionRegion
719 instead of the wave chunk
720 - fixed keyswitching for v3 gigs with a number of keyswitch splits
721 not equal to a power of two
722 - reimplementation of the filter algorithm. The new filter is more
723 accurate and supports all gig filter types, including bandreject
724 and lowpass turbo.
725 - real support for 24 bit samples - samples are not truncated to
726 16 bits anymore
727 - support for aftertouch (channel pressure, not polyphonic
728 aftertouch)
729 - LFO1 behaviour fixed (dampening from max volume instead of
730 amplifying from 0)
731
732 * LSCP server:
733 - fixed application exit on broken pipe error (fixes bug #20)
734 - fixed the notification messages delay due to lack of
735 network activity (fixes bug #26)
736 - fixed parser bug which occured on space(s) within device parameters
737 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
738
739 * audio driver:
740 - added aRts audio output driver (by no means RT safe)
741
742 * MIDI driver:
743 - fixed legacy sysex code which caused dispatching of MIDI SysEx
744 messages several times instead of once
745 - API extension for MIDI drivers which already supply exact time stamps
746 for events (i.e. for offline rendering based MIDI drivers)
747 - added checks for bad MIDI data
748
749 * linuxsampler application:
750 - show available sampler engine types on startup
751
752 * general changes:
753 - support for muting sampler channels and solo mode of the same, two new
754 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
755 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
756 introduced for this, the behavior is the same like on a mixer console
757 (patch by Grigor Iliev, a bit adjusted). Also added configure option
758 --enable-process-muted-channels which can be used to enable the
759 processing of muted channels.
760 - support for sostenuto pedal
761 - support for monitoring the total number of active voices
762 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
763 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
764 - fixed some memory management errors
765 - fixed some concurrency problems that could lead to crashes when
766 LSCP commands were executed
767 - fixed crash when instrument loading failed previously on the same
768 sampler channel (fixes bug #36)
769
770 Version 0.3.3 (15 July 2005)
771
772 * packaging changes:
773 - fixed compilation with gcc 4.0
774
775 * Gigasampler format engine:
776 - LFO preprocessing was performed even though the respective LFO was
777 disabled by the instrument patch (minor efficiency fix)
778 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
779 for volume ramp downs in the same fragment (needed for current voice
780 stealing implementation) then simply inform the user with a warning
781 about possible click sounds and reduce the volume ramp down
782 appropriately instead of cancelling the audio device connection
783
784 Version 0.3.2 (24 June 2005)
785
786 * packaging changes:
787 - updated autotools build files to compile on OS X
788 (conditional compilation of CoreMIDI and MidiShare drivers)
789 - hand-crafted assembly optimization code can be disabled with
790 './configure --disable-asm' (definitely not recommended)
791 - fixed 'make dist' rule to include all necessary files
792 - require automake (>= 1.5) for 'make -f Makefile.cvs'
793 (due to 'dist-bzip2' automake option)
794
795 * Gigasampler format engine:
796 - support for the gig parameters for "release velocity response" curves
797 - fine tuning of the EGADSR envelope
798 - volume of release triggered samples now depends on note-on velocity,
799 note length and gig parameter "release trigger decay" instead of
800 note-off velocity.
801 - revised voice stealing
802 (fixes crash and endless loop caused by voice stealing)
803 - don't reset scale tuning on instrument or audio output device change
804 - handle key group conflicts right at the beginning of each fragment
805 instead of when the respective voice is actually launched
806 (fixes undefined behavior if stolen voices belonged to a key group -
807 this case was followed by a "killed voice survived" error message)
808 - fixed minor issue with null/silence samples
809 (those stole voices even though they don't need a voice at all which
810 resulted in "voice stealing didn't work out" messages)
811 - don't reset volume, pan, pitch and MIDI controller values on
812 instrument or audio output device change
813
814 * LSCP server:
815 - fixed some crashes (patch by Grigor Iliev, fixes #19)
816 - fixed LSCP event "CHANNEL_INFO" notification
817 (e.g. did not notify on volume changes or MIDI program change events)
818
819 * linuxsampler application:
820 - added command line parameters --lscp-addr and --lscp-port to override
821 default IP address and port of LSCP server
822
823 Version 0.3.1 (24 May 2005)
824
825 * initial release
