2
3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
5
6 * packaging changes:
7 - fixed building with newer MinGW-w64

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

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

227 channel to a different engine type
228 - fixed crash when deleting a sampler channel or changing engine
229 type while an instrument load was in progress
230 - bugfix: playing a note while changing the instrument could cause
231 a crash, or give "Handing back unknown region" error messages
232 - bugfix: calling SET VOICES (which Fantasia does on start and
233 refresh) could cause instruments to be unloaded
234 - Mac OS X: fixed name collision of enum in EffectControl and

241
242 Version 1.0.0 (31 July 2009)
243
244 * packaging changes:
245 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
246 causing e.g. the libgig test to fail when
247 "./configure --disable-jack-driver" was used
248 (patch by Alexis Ballier)
249 - fixed compilation with gcc 4.3
250 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

252 - fixes for building with newer MinGW versions
253 - fix for building with bison 2.4 (#111)
254 - fixed building with libgig installed in a non-standard directory
255 - minor fix in configure for mmsystem.h detection on MinGW
256 - Windows: look for editor plugins and Fantasia using base
257 directory of liblinuxsampler dll (look in the same directory and one
258 directory above)
259 - configure script fix: removed unconditional use of SSE
260 - fixed building with sqlite installed in a non-standard directory
261 - when cross-compiling, don't try to create instruments.db
262 - fix for new mingw-w64 version, which has usleep
263
264 * general changes:
265 - bugfix: on some POSIX systems instrument editor plugins refused to
266 load as we used a non-portable Linux specific struct field
267 (fixes bug #70, patch by Ronald Baljeu)
268 - fixed endless loop which occured when loading an instrument editor
269 plugin DLL on Windows systems failed
270 - fixed memory leaks that occurred when liblinuxsampler was unloaded
271 - optimized the SynchronizedConfig class so it doesn't wait
272 unnecessarily long after an update
273 - added support for notifying instrument editors on note-on / note-off
274 events (e.g. to highlight the pressed keys on the virtual keyboard
275 of gigedit)
276 - added support for triggering notes by instrument editors (see above)
277 - be verbose on DLL load errors (on Linux)
278 - fixed di-harmonic triangle LFO implementation (this LFO implementation
279 is only used by very few systems, most pick the int math
280 implementation, which is usually faster)
281 - fixes for audio drivers with varying buffer sizes
282 - experimental support for running LinuxSampler as a DSSI, LV2 and
283 VST plugin
284 - notification events for stream/voice count statistics are now sent
285 only when there are actual changes
286 - added memory ordering constraints to improve stability on
287 multi-core and multi-cpu systems
288 - maximum voices and disk streams can now be altered at runtime
289 - fixed CPU feature detection on x86_64 (maybe fixes #108)
290 - automatic stacktrace mechanism is now turned off by default and can
291 be switched on by command line option "--stacktrace" (the automatic
292 stacktrace mechanism seems to be broken on most systems at the moment)
293 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
294 a pointer to the launched InstrumentEditor object
295 - added optional 3rd party user data parameter for following
296 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
297 InstrumentEditor::Launch(),
298 InstrumentManager::LaunchInstrumentEditor()
299 - theoretical fix: made SynchronizedConfig follow C++0x memory
300 model more strictly
301 - fixes for using large audio device buffers
302 - Windows: add the installation directory to the DLL search path
303 when loading an editor plugin (solves problems with VST and
304 gigedit on systems with other GTK versions installed)
305
306 * audio driver:
307 - removed the nonsense audio channel constraint (which was hard coded to
308 max. 100 audio channels) for most audio drivers
309 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
310 opposed to the LSCP specs
311 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
312 reflected the wrong value
313 - fixed a memory management bug in ASIO driver
314 - Makefile fix: JACK_CFLAGS wasn't used
315 - JACK: use jack_client_open instead of the deprecated
316 jack_client_new
317 - added (experimental) CoreAudio driver
318 - applied old fixes to the ASIO driver that were included in the
319 previous binary release but accidentally never committed to CVS
320 (fixes #117)
321 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
322 win64)
323 - VST: added support for sample rate and buffer size changes
324 - VST: close editor (Fantasia) when the VST is removed
325 - VST: avoid opening Fantasia more than once for each VST instance
326 - VST: export main function as "main" on Linux too (fix for
327 energyXT)
328 - VST: changed number of output channels from one stereo to 16
329 stereo
330 - added channel routing, fxsends and midi maps to the settings
331 stored in the plugin state
332 - performance optimization of AudioChannel::MixTo() and
333 AudioChannel::CopyTo() methods using GCC vector exensions
334 (if available)
335 - ASIO fixes: avoid initializing the device twice, avoid throwing
336 exception when getting parameters from a disconnected device
337
338 * MIDI driver:
339 - added JACK MIDI driver
340 - dispatch bank select as ordinary CC as well, the user might seriously
341 want to (mis)use it for some purpose ("fixed" in all current MIDI
342 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
343 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
344 CoreMidi or AU
345 - fixed mingw-w64 compilation error in MME driver
346 - made program change handling in MIDI thread real-time safe by
347 moving the logic to a non-RT thread
348 - fixed minor memory leak in ALSA driver
349
350 * instruments database:
351 - avoid time consuming samples scanning when adding instruments
352 to the instruments database
353 - added support for handling lost files in the instruments database
354 - Implemented option for adding instruments in separate directories
355 in the instruments database
356 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
357 - work-around for missing fnmatch function on Windows to make
358 instrument database compilable
359 - added instrument database support on Windows
360 works with both standalone mode and VST plugin.
361 the instruments DB file is located in
362 %USERPROFILE%\.linuxsampler\instruments.db which allows different
363 databases for each windows user
364 if no DB is present it automatically creates the .linuxsampler subdir
365 and then creates an empty DB
366 - fixed recursive import, which was broken on Windows
367
368 * Gigasampler format engine:
369 - fixed a memory leak that could happen when a channel was deleted
370 while notes were playing
371 - made it possible to load an instrument even if the audio thread
372 isn't running
373 - added partial support for the "Controller Triggered" MIDI rule,
374 enough for piano gigs with pedal noise samples
375 - minor fix: only mark FX sends as being modified if really the
376 respective FX send MIDI controller was used
377 - added support for GM global device volume SysEx message
378 (can be selected at compile time to either apply globally to the
379 whole sampler [default] or only to the sampler channels that are
380 connected to the respective MIDI input port the SysEx message arrived
381 on)
382 - bugfix: notes triggered at position 0 in the audio buffer were
383 sometimes wrongly killed in the same buffer, causing no sound to
384 be played
385 - added support for chromatic / drumkit mode Roland GS Sysex message
386 which is usally used to switch a part between chromatic sounds and
387 drumkit sounds (as opposed to their common default setting of MIDI
388 part 10 being a drumkit part and all other ones chromatic parts), in
389 LS however one can switch between the first 16 MIDI instrument maps
390 defined for the sampler
391 - made it possible to create multiple sample channels even if the
392 audio thread isn't running
393 - fixed crash when removing channel with active voices (#116)
394 - bugfix: on sample reference changes (instrument editor), only
395 un-cache the respective sample if it's really not used by any
396 sampler engine anymore
397 - re-cache samples in case they were changed by an instrument editor,
398 e.g. when a sample was added while playing (#82)
399 - fixed hanging notes which occured when note-off event had the exact
400 same time stamp as the voice's note-on event and occured both in the
401 same audio fragment cycle (fixes bug #112)
402 - added support for the "fine tune" and "pitch bend range"
403 instrument-level gig parameters
404 - fixed minor artifacts in pitch bend handling
405 - added support for GS Reset SysEx message
406 - allow gig files to use unlimited downward pitch shifting
407 - added a limit check for upward pitch shifting
408 - bugfix: sometimes, when playing a note twice fast, the second
409 note was silent
410 - fixed crash happening when a pitch bend event arrived at the
411 same time a new instrument was loading
412
413 * LSCP server:
414 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
415 react on MIDI data arriving on certain sampler channels (so far only
416 Note-On and Note-Off events are sent via this LSCP event)
417 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
418 react on MIDI data arriving on certain MIDI input devices (so far only
419 Note-On and Note-Off events are sent via this LSCP event)
420 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
421 SET DB_INSTRUMENT FILE_PATH
422 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
423 frontends to send MIDI messages to specific sampler channel
424 - added two additional fields to GET FILE INSTRUMENT INFO command -
425 KEY_BINDINGS and KEYSWITCH_BINDINGS
426 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
427 was incorrect
428 - Optimized the retrieval of the MIDI instrument mappings
429 - added new LSCP command "SET VOICES" to globally alter the maximum
430 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
431 be triggered respectively
432 - added new LSCP command "SET STREAMS" to globally alter the maximum
433 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
434 which will be triggered respectively
435 - bugfix: retry if "select" returns EINTR (this fixes a crash when
436 a gigedit file dialog is opened)
437 - close all connections when LSCPServer is deleted
438 - hard close of all sockets on exit
439 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
440 driver
441
442 * Bug fixes:
443 - fixed a crash which occurs when removing a sampler channel waiting
444 to start instrument loading after another channel
445 - fixed a crash which occurs when removing a sampler channel with
446 instrument loading in progress (bug #113)
447 - fixed termination caused by uncaught exception when adding MIDI
448 instrument with PERSISTENT load mode
449 - fixed possible iterator invalidations when resetting the sampler
450 - fixed memory leaks when issuing the following LSCP commands:
451 GET AUDIO_OUTPUT_DRIVER INFO
452 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
453 GET MIDI_INPUT_DRIVER INFO
454 GET MIDI_INPUT_DRIVER_PARAMETER INFO
455 - fixed possible compilation error when sqlite is not present
456 - fixed orphaned pointers when setting maximum voices limit (bug #118)
457 - fixed crash when changing the audio output device of a sampler
458 channel with loaded instrument and start playing notes
459 - fixed endless loop in Engine::SuspendAll() (bug #120)
460 - fixed a low-level atomic load function that was broken on 64-bit
461 PowerPC, which probably could cause crashes on that platform
462 - fixed a memory management error which could cause a crash when a
463 plugin was unloaded
464 - bugfix: two private structs had the same name, which could cause
465 problems if the linker chose the wrong constructor
466 - fixed low-level ConditionServer usage bug that caused lockups on
467 Windows

470 Version 0.5.1 (6 December 2007)
471
472 * packaging changes:
473 - added autoconf checks for pthread library
474 - added autoconf check for pthread bug found on certain NPTL-enabled
475 glibc versions (see Gentoo bug report #194076)
476 - added autoconf checks for MS Windows
477
478 * general changes:
479 - bugfix: the thread used by an editor plugin didn't die when the
480 editor closed
481 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
482 out all the space. operator--() did not apply size_mask after
483 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
484 order to avoid problems with the _NonVolatileReader functions.
485 - bugfix: Stream.h: added a missing divide by BytesPerSample in
486 GetWriteSpace(). Since this function is currently only used in
487 the stream's qsort() compare function, it didn't trigger any
488 bugs.
489 - Resampler.h, Synthesizer.h: cubic interpolation now works in
490 24bit mode too. Faster method to read 24bit words on little
491 endian machines (x86): replaced 3 byte reads + shifts with a 1
492 unaligned 32bit read and shift
493 - experimental support for MS Windows (MIDI input via MME, AUDIO
494 output via ASIO)
495 - made handling of SIGINT signal (Ctrl-C) a bit more robust
496 - support for monitoring the total number of active disk streams
497 (new LSCP commands: GET TOTAL_STREAM_COUNT,
498 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
499
500 * AUDIO driver:
501 - added Windows ASIO low latency audio driver
502
503 * MIDI driver:
504 - added MME Windows MIDI driver
505
506 * LSCP server:
507 - added support for Windows style path / filenames, however with
508 forward slash path separators instead of backslash
509 (i.e. "C:/foo/bar.gig")
510 - allow naughty liblscp to send non-string device parameters within
511 apostrophes as well
512 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
513 "LIST FILE INSTRUMENTS <file>" and
514 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
515 about an arbitrary instrument file on the system where the sampler is
516 running on
517
518 Version 0.5.0 (15 October 2007)
519
520 * packaging changes:
521 - config.h is not going to be installed along with liblinuxsampler's
522 API header files anymore
523 - only the API relevant header (and source) files will be exported to
524 the Doxygen API documentation (explicitly listed in Doxyfile.in)
525 - added completely new XCode project files for Mac OSX which is now
526 capable to execute our autoconf environment, thus no need anymore
527 to maintain the compile time configuration file (osx/version.h) for
528 OSX manually (patch by Toshi Nagata)
529 - fixed buggy boolean --enable-foo / --disable-foo configure script
530 parameters
531 - global.h now only covers global definitions that are needed for the
532 C++ API header files, all implementation internal global definitions
533 are now in global_private.h
534 - atomic.h is not exposed to the C++ API anymore
535 - no need to include config.h anymore for using LS's API header files
536 - fixed warnings in API doc generation
537
538 * general changes:
539 - replaced the old, confusing MIDI program change mechanism by a
540 flexible MIDI instrument mapper which allows to map arbitrary
541 (MIDI bank, MIDI program) pairs with arbitrary
542 (engine type, instrument file, file index) triplets which will be
543 loaded on the respective channel when such MIDI program change
544 messages arrive, beside that, each entry allows to define a life-time
545 strategy for the instrument, so the user can define whether the
546 instrument should i.e. be permanently loaded (to be able to switch
547 quickly among sounds) or i.e. loaded just on demand when the
548 respective program change arrives (to safe RAM space), as well as a
549 global volume factor for each entry, so the user can adjust the volume
550 dynamic of his mapped instrument collection without having to modify
551 the instrument files, also one can manage arbitrary amount of such
552 MIDI instrument maps and assign each sampler channel individually
553 a certain map, so that i.e. separation of normal instruments and
554 drumkits is possible
555 - new notification events for tracking changes to audio/MIDI devices,
556 MIDI instrument maps, MIDI instruments, FX sends, global volume.
557 - sampler was limited to load max. 200 instruments in the background
558 due to a constant size RingBuffer FIFO which is now replaced by a
559 dynamic (unlimited) size std::list FIFO
560 - added FX sends, these allow to route audio signals to arbitrary audio
561 output channels for being processed by external effect processors
562 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
563 controllers
564 - global (sampler wide) volume can now be controlled at runtime
565 - Implemented new, improved notification system
566 - fixed compilation errors regarding OSX
567 (patch by Toshi Nagata)
568 - implemented instruments database
569 - added support for escape sequences to the instruments database
570 - added highly experimental support for on-the-fly instrument editing
571 within the sampler's process (by using instrument editor plugins),
572 you'll notice the new "Registered instrument editors:" message on
573 startup, added a new LSCP command:
574 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
575 to spawn a matching instrument editor for the instrument on the
576 given sampler channel, the plugin path can be overridden at compile
577 time with ./configure --enable-plugin-dir=/some/dir
578 - added experimental code for synchronizing instrument editors hosted
579 in the sampler's process to safely edit instruments while playing
580 without a crash (hopefully) by either suspending single regions
581 wherever possible or if unavoidable whole engine(s)
582 - fixed several issues in fundamental "Thread" class: set scheduling
583 policy and priority on thread level, set a minimum stack size for
584 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
585 threads simply inherited properties of starting thread instead of
586 setting their own policy and priority
587 - minor fix in our automatic stack trace mechanism on crashes, the
588 main process did not wait for the stack trace process to finish
589 its output
590 - fixed some minor memory leaks
591 - reenabled assembly features support, at the moment only for
592 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
593 - minor assembly fix in x86 features detection (don't use the PIC
594 register, to avoid relocations in the text segment at runtime)
595 - POSIX callback functions of Thread.h are hidden
596
597 * MIDI driver:
598 - dispatch bank select (MSB and LSB) messages
599
600 * audio driver:
601 - the ALSA audio output driver parameters now reflect the correct
602 parameter value ranges for the respective selected sound card
603 (patch by Till Wimmer, a bit fixed and extended)
604
605 * Gigasampler format engine:
606 - if a filter is used and EG2 finishes before EG1, let the voice
607 die when EG2 has finished (this fixes a problem with clicks and
608 voice starvation for some gigs)
609 - playback is no longer disabled during instrument loading
610 - all notes playing on a channel that changes its instrument keep
611 playing with the old instrument until they get a note off
612 command
613 - EG fix: a release value of zero could cause noises or crash
614 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
615 - EG fine tuning: when attack is zero the EG starts at a level
616 above max sustain level, which means that there is a decay phase
617 even if sustain is 100%
618 - more EG fixes: the level could sometimes go below zero and cause
619 noises or crashes
620 - minor fix of EGDecay (patch by Toshi Nagata)
621 - fixed compiler error when --enable-override-filter-type was
622 supplied to the configure script (fixes #46)
623 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
624 instead of a fix value
625 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
626 127 (solo mode) only kill voices if the respective mode really
627 changed
628
629 * LSCP server:
630 - fixed compile time error for old Bison versions
631 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
632 - parser now supports extended ASCII character set
633 (up to ASCII code 255, i.e. includes now umlauts and accents)
634 - filename arguments in LSCP commands now allow to use escape
635 sequences, that is directly literal as one of: \', \", \\, \n, \r,
636 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
637 code value like \xf2) (fixes bug #24)
638 - the following LSCP commands now also support escape sequences for at
639 least one of their text-based parameters (i.e. name, description):
640 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
641 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
642 "SET DB_INSTRUMENT_DIRECTORY NAME",
643 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
644 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
645 "FIND DB_INSTRUMENT_DIRECTORIES"
646 - returns verbose syntax errors (line and column where syntax error
647 occured, the unexpected character and the actually expected, possible
648 character(s), the latter only if less than 5 possibilities)
649 - made sure that LSCP syntax is not affected by gigedit locale
650 settings
651 - bugfix regarding strings parameter lists: all comma separated lists
652 of strings were treated as being one string containing commas
653 (fixes #57)
654
655 * Bug fixes:
656 - fixed crash occurring on certain LSCP scripts (Bug 39)
657 - another thread safety fix for lscp "load engine" and "set
658 channel audio output device"
659 - fixed a crash which occurs when reassigning the same engine
660 on a sampler channel with connected MIDI device
661 - fixed a crash which occurs when changing the number of ports of a MIDI
662 device connected to a sampler channel to number less then or equal
663 to the index of the port to which the sampler channel is connected.
664 - The previous bindings were not been disconnected when altering
665 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
666 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
667 - The active stream/voice count statistic was incorrect.
668 - notification events were not been sent for some sampler
669 channel changes
670 - added default min and max values to restrict the number of allowed
671 audio output channels and MIDI input ports
672 - the connection to the PCM interface is now closed when destroying
673 an audio output device
674 - files with slash in their path or filename could not be loaded
675
676 * test cases:
677 - updated and fixed (haven't been touched in a while)
678
679 Version 0.4.0 (24 November 2006)
680
681 * packaging changes:
682 - changed deprecated copyright attribute to license; added ldconfig
683 to post-(un)install steps; added devel package for liblinuxsampler;
684 to linuxsampler.spec (RPM)
685 - install necessary development header files for allowing 3rd party
686 applications to link against liblinuxsampler
687 - liblinuxsampler's API documentation can be generated with 'make docs'
688 (Doxygen required)
689 - added benchmark to automatically detect the best triangle LFO
690 implementation (currently either an integer math solution or a
691 di-harmonic approximation), automatic detection can be overriden
692 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
693 configure script argument though (mandatory for cross-compilation)
694 - do not automatically pick optimized gcc flags if the user already
695 provided some on his own (as CXXFLAGS)
696 - added compile time option to disable processing of All-Notes-Off MIDI
697 messages
698 - added compile time options to allow disabling the various audio and
699 MIDI drivers
700 - fixed automatic GCC CPU switch detection on PPC
701 (patch by Ebrahim Mayat)
702
703 * Gigasampler format engine:
704 - extensive synthesis optimization
705 (reimplementation of EGs and LFO(s), removed synthesis parameter
706 prerendering and the synthesis parameter matrix in general, splitting
707 each audio fragment into subfragments now where each subfragment uses
708 constant pitch and filter coefficients. The volume coefficient is
709 linearly interpolated inside a subfragment, unless
710 --disable-interpolate-volume is set.)
711 - fine tuning of the EG modulation parameters
712 - improved filter cutoff calculation by adding support for the
713 following gig parameters: Cutoff freq (used when no cutoff
714 controller is defined), Control invert, Minimum cutoff, Velocity
715 curve and Velocity range. The keyboard tracking now scales
716 cutoff frequency instead of resonance.
717 - added support for gig parameter Resonance.
718 - fixed bug in sysex handling (patch by Juan Linietsky)
719 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
720 which can be overridden with --enable-global-attenuation
721 - EG fixes: made the length of "attack hold" stage more
722 accurate. Release stage can now start before attack stage
723 ends. Cancel release didn't work when sustain was zero. Attack
724 time now has a minimal value to prevent clicks.
725 - fixed pitch changes larger than one octave
726 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
727 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
728 all modes can be altered via standard GM messages, that is CC5 for
729 altering portamento time, CC65 for enabling / disabling portamento
730 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
731 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
732 parameter) and crossfade
733 - added support for the "attenuation controller threshold" gig
734 parameter
735 - added smoothing of volume changes caused by control change
736 messages
737 - sample loop parameters are now taken from the DimensionRegion
738 instead of the wave chunk
739 - fixed keyswitching for v3 gigs with a number of keyswitch splits
740 not equal to a power of two
741 - reimplementation of the filter algorithm. The new filter is more
742 accurate and supports all gig filter types, including bandreject
743 and lowpass turbo.
744 - real support for 24 bit samples - samples are not truncated to
745 16 bits anymore
746 - support for aftertouch (channel pressure, not polyphonic
747 aftertouch)
748 - LFO1 behaviour fixed (dampening from max volume instead of
749 amplifying from 0)
750
751 * LSCP server:
752 - fixed application exit on broken pipe error (fixes bug #20)
753 - fixed the notification messages delay due to lack of
754 network activity (fixes bug #26)
755 - fixed parser bug which occured on space(s) within device parameters
756 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
757
758 * audio driver:
759 - added aRts audio output driver (by no means RT safe)
760
761 * MIDI driver:
762 - fixed legacy sysex code which caused dispatching of MIDI SysEx
763 messages several times instead of once
764 - API extension for MIDI drivers which already supply exact time stamps
765 for events (i.e. for offline rendering based MIDI drivers)
766 - added checks for bad MIDI data
767
768 * linuxsampler application:
769 - show available sampler engine types on startup
770
771 * general changes:
772 - support for muting sampler channels and solo mode of the same, two new
773 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
774 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
775 introduced for this, the behavior is the same like on a mixer console
776 (patch by Grigor Iliev, a bit adjusted). Also added configure option
777 --enable-process-muted-channels which can be used to enable the
778 processing of muted channels.
779 - support for sostenuto pedal
780 - support for monitoring the total number of active voices
781 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
782 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
783 - fixed some memory management errors
784 - fixed some concurrency problems that could lead to crashes when
785 LSCP commands were executed
786 - fixed crash when instrument loading failed previously on the same
787 sampler channel (fixes bug #36)
788
789 Version 0.3.3 (15 July 2005)
790
791 * packaging changes:
792 - fixed compilation with gcc 4.0
793
794 * Gigasampler format engine:
795 - LFO preprocessing was performed even though the respective LFO was
796 disabled by the instrument patch (minor efficiency fix)
797 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
798 for volume ramp downs in the same fragment (needed for current voice
799 stealing implementation) then simply inform the user with a warning
800 about possible click sounds and reduce the volume ramp down
801 appropriately instead of cancelling the audio device connection
802
803 Version 0.3.2 (24 June 2005)
804
805 * packaging changes:
806 - updated autotools build files to compile on OS X
807 (conditional compilation of CoreMIDI and MidiShare drivers)
808 - hand-crafted assembly optimization code can be disabled with
809 './configure --disable-asm' (definitely not recommended)
810 - fixed 'make dist' rule to include all necessary files
811 - require automake (>= 1.5) for 'make -f Makefile.cvs'
812 (due to 'dist-bzip2' automake option)
813
814 * Gigasampler format engine:
815 - support for the gig parameters for "release velocity response" curves
816 - fine tuning of the EGADSR envelope
817 - volume of release triggered samples now depends on note-on velocity,
818 note length and gig parameter "release trigger decay" instead of
819 note-off velocity.
820 - revised voice stealing
821 (fixes crash and endless loop caused by voice stealing)
822 - don't reset scale tuning on instrument or audio output device change
823 - handle key group conflicts right at the beginning of each fragment
824 instead of when the respective voice is actually launched
825 (fixes undefined behavior if stolen voices belonged to a key group -
826 this case was followed by a "killed voice survived" error message)
827 - fixed minor issue with null/silence samples
828 (those stole voices even though they don't need a voice at all which
829 resulted in "voice stealing didn't work out" messages)
830 - don't reset volume, pan, pitch and MIDI controller values on
831 instrument or audio output device change
832
833 * LSCP server:
834 - fixed some crashes (patch by Grigor Iliev, fixes #19)
835 - fixed LSCP event "CHANNEL_INFO" notification
836 (e.g. did not notify on volume changes or MIDI program change events)
837
838 * linuxsampler application:
839 - added command line parameters --lscp-addr and --lscp-port to override
840 default IP address and port of LSCP server
841
842 Version 0.3.1 (24 May 2005)
843
844 * initial release
