File size: 48637 byte(s)
* Introduced new C++ API method EngineChannel::InstrumentFileName(int index)
  allowing to retrieve the whole list of files used for the loaded
  instrument on an engine channel (a.k.a. part). Some GigaStudio instruments
  for example are splitted over several files like "Foo.gig", "Foo.gx01",
  "Foo.gx02", ...
* Bumped version to 1.0.0.svn18

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 "state" extension 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 - implemented sine LFO, pulse LFO and saw LFO
45 - experimental support for per voice equalization
46 - added command line option --exec-after-init
47 - Introduced new C++ API method:
48 EngineChannel::InstrumentFileName(int index)
49 allowing to retrieve the whole list of files used for the loaded
50 instrument on an engine channel (a.k.a. part). Some GigaStudio
51 instruments for example are splitted over several files like
52 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
53

307 a crash, or give "Handing back unknown region" error messages
308 - bugfix: calling SET VOICES (which Fantasia does on start and
309 refresh) could cause instruments to be unloaded
310 - Mac OS X: fixed name collision of enum in EffectControl and
311 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
312 - Mac OS X: fixed hanging threads
313 - Windows: disabled the previous thread fix on non-Mac systems, as
314 it caused hanging threads on Windows
315 - Fixed possible crashes due to corrupted MIDI/audio device list
316 after MIDI/audio device creation failure
317 - When creating MIDI instrument map entries with "PERSISTENT" type, the
318 instruments were uselessly precached with zero samples, however it still
319 took the full preloading time and on 1st program change the respective
320 instrument was completely reloaded again.
321 - fixed handling of rapid bank select and program change messages
322 sent to the same sampler channel (patch from the Open Octave
323 project, slightly adjusted)

336
337 * packaging changes:
338 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
339 causing e.g. the libgig test to fail when
340 "./configure --disable-jack-driver" was used
341 (patch by Alexis Ballier)
342 - fixed compilation with gcc 4.3
343 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

345 - fixes for building with newer MinGW versions
346 - fix for building with bison 2.4 (#111)
347 - fixed building with libgig installed in a non-standard directory
348 - minor fix in configure for mmsystem.h detection on MinGW
349 - Windows: look for editor plugins and Fantasia using base
350 directory of liblinuxsampler dll (look in the same directory and one
351 directory above)
352 - configure script fix: removed unconditional use of SSE
353 - fixed building with sqlite installed in a non-standard directory
354 - when cross-compiling, don't try to create instruments.db
355 - fix for new mingw-w64 version, which has usleep
356
357 * general changes:
358 - bugfix: on some POSIX systems instrument editor plugins refused to
359 load as we used a non-portable Linux specific struct field
360 (fixes bug #70, patch by Ronald Baljeu)
361 - fixed endless loop which occured when loading an instrument editor
362 plugin DLL on Windows systems failed
363 - fixed memory leaks that occurred when liblinuxsampler was unloaded
364 - optimized the SynchronizedConfig class so it doesn't wait
365 unnecessarily long after an update
366 - added support for notifying instrument editors on note-on / note-off
367 events (e.g. to highlight the pressed keys on the virtual keyboard
368 of gigedit)
369 - added support for triggering notes by instrument editors (see above)
370 - be verbose on DLL load errors (on Linux)
371 - fixed di-harmonic triangle LFO implementation (this LFO implementation
372 is only used by very few systems, most pick the int math
373 implementation, which is usually faster)
374 - fixes for audio drivers with varying buffer sizes
375 - experimental support for running LinuxSampler as a DSSI, LV2 and
376 VST plugin
377 - notification events for stream/voice count statistics are now sent
378 only when there are actual changes

380 multi-core and multi-cpu systems
381 - maximum voices and disk streams can now be altered at runtime
382 - fixed CPU feature detection on x86_64 (maybe fixes #108)
383 - automatic stacktrace mechanism is now turned off by default and can
384 be switched on by command line option "--stacktrace" (the automatic
385 stacktrace mechanism seems to be broken on most systems at the moment)
386 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
387 a pointer to the launched InstrumentEditor object
388 - added optional 3rd party user data parameter for following
389 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
390 InstrumentEditor::Launch(),
391 InstrumentManager::LaunchInstrumentEditor()
392 - theoretical fix: made SynchronizedConfig follow C++0x memory
393 model more strictly
394 - fixes for using large audio device buffers
395 - Windows: add the installation directory to the DLL search path
396 when loading an editor plugin (solves problems with VST and
397 gigedit on systems with other GTK versions installed)
398
399 * audio driver:
400 - removed the nonsense audio channel constraint (which was hard coded to
401 max. 100 audio channels) for most audio drivers
402 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
403 opposed to the LSCP specs
404 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
405 reflected the wrong value
406 - fixed a memory management bug in ASIO driver
407 - Makefile fix: JACK_CFLAGS wasn't used
408 - JACK: use jack_client_open instead of the deprecated
409 jack_client_new
410 - added (experimental) CoreAudio driver
411 - applied old fixes to the ASIO driver that were included in the
412 previous binary release but accidentally never committed to CVS
413 (fixes #117)

415 win64)
416 - VST: added support for sample rate and buffer size changes
417 - VST: close editor (Fantasia) when the VST is removed
418 - VST: avoid opening Fantasia more than once for each VST instance
419 - VST: export main function as "main" on Linux too (fix for
420 energyXT)
421 - VST: changed number of output channels from one stereo to 16
422 stereo
423 - added channel routing, fxsends and midi maps to the settings
424 stored in the plugin state
425 - performance optimization of AudioChannel::MixTo() and
426 AudioChannel::CopyTo() methods using GCC vector exensions
427 (if available)
428 - ASIO fixes: avoid initializing the device twice, avoid throwing
429 exception when getting parameters from a disconnected device
430
431 * MIDI driver:
432 - added JACK MIDI driver
433 - dispatch bank select as ordinary CC as well, the user might seriously
434 want to (mis)use it for some purpose ("fixed" in all current MIDI
435 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
436 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
437 CoreMidi or AU
438 - fixed mingw-w64 compilation error in MME driver
439 - made program change handling in MIDI thread real-time safe by
440 moving the logic to a non-RT thread
441 - fixed minor memory leak in ALSA driver
442
443 * instruments database:
444 - avoid time consuming samples scanning when adding instruments
445 to the instruments database
446 - added support for handling lost files in the instruments database
447 - Implemented option for adding instruments in separate directories
448 in the instruments database
449 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
450 - work-around for missing fnmatch function on Windows to make
451 instrument database compilable
452 - added instrument database support on Windows
453 works with both standalone mode and VST plugin.
454 the instruments DB file is located in
455 %USERPROFILE%\.linuxsampler\instruments.db which allows different
456 databases for each windows user
457 if no DB is present it automatically creates the .linuxsampler subdir
458 and then creates an empty DB
459 - fixed recursive import, which was broken on Windows
460
461 * Gigasampler format engine:
462 - fixed a memory leak that could happen when a channel was deleted
463 while notes were playing
464 - made it possible to load an instrument even if the audio thread
465 isn't running
466 - added partial support for the "Controller Triggered" MIDI rule,
467 enough for piano gigs with pedal noise samples
468 - minor fix: only mark FX sends as being modified if really the
469 respective FX send MIDI controller was used
470 - added support for GM global device volume SysEx message
471 (can be selected at compile time to either apply globally to the
472 whole sampler [default] or only to the sampler channels that are
473 connected to the respective MIDI input port the SysEx message arrived
474 on)
475 - bugfix: notes triggered at position 0 in the audio buffer were
476 sometimes wrongly killed in the same buffer, causing no sound to
477 be played
478 - added support for chromatic / drumkit mode Roland GS Sysex message
479 which is usally used to switch a part between chromatic sounds and
480 drumkit sounds (as opposed to their common default setting of MIDI
481 part 10 being a drumkit part and all other ones chromatic parts), in
482 LS however one can switch between the first 16 MIDI instrument maps
483 defined for the sampler
484 - made it possible to create multiple sample channels even if the
485 audio thread isn't running
486 - fixed crash when removing channel with active voices (#116)
487 - bugfix: on sample reference changes (instrument editor), only
488 un-cache the respective sample if it's really not used by any
489 sampler engine anymore
490 - re-cache samples in case they were changed by an instrument editor,
491 e.g. when a sample was added while playing (#82)
492 - fixed hanging notes which occured when note-off event had the exact
493 same time stamp as the voice's note-on event and occured both in the
494 same audio fragment cycle (fixes bug #112)
495 - added support for the "fine tune" and "pitch bend range"
496 instrument-level gig parameters
497 - fixed minor artifacts in pitch bend handling
498 - added support for GS Reset SysEx message
499 - allow gig files to use unlimited downward pitch shifting
500 - added a limit check for upward pitch shifting
501 - bugfix: sometimes, when playing a note twice fast, the second
502 note was silent
503 - fixed crash happening when a pitch bend event arrived at the
504 same time a new instrument was loading
505
506 * LSCP server:
507 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
508 react on MIDI data arriving on certain sampler channels (so far only
509 Note-On and Note-Off events are sent via this LSCP event)
510 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
511 react on MIDI data arriving on certain MIDI input devices (so far only
512 Note-On and Note-Off events are sent via this LSCP event)
513 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
514 SET DB_INSTRUMENT FILE_PATH
515 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
516 frontends to send MIDI messages to specific sampler channel
517 - added two additional fields to GET FILE INSTRUMENT INFO command -
518 KEY_BINDINGS and KEYSWITCH_BINDINGS
519 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
520 was incorrect
521 - Optimized the retrieval of the MIDI instrument mappings
522 - added new LSCP command "SET VOICES" to globally alter the maximum
523 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
524 be triggered respectively
525 - added new LSCP command "SET STREAMS" to globally alter the maximum
526 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
527 which will be triggered respectively
528 - bugfix: retry if "select" returns EINTR (this fixes a crash when
529 a gigedit file dialog is opened)
530 - close all connections when LSCPServer is deleted
531 - hard close of all sockets on exit
532 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
533 driver
534
535 * Bug fixes:
536 - fixed a crash which occurs when removing a sampler channel waiting
537 to start instrument loading after another channel
538 - fixed a crash which occurs when removing a sampler channel with
539 instrument loading in progress (bug #113)
540 - fixed termination caused by uncaught exception when adding MIDI
541 instrument with PERSISTENT load mode
542 - fixed possible iterator invalidations when resetting the sampler
543 - fixed memory leaks when issuing the following LSCP commands:
544 GET AUDIO_OUTPUT_DRIVER INFO
545 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
546 GET MIDI_INPUT_DRIVER INFO
547 GET MIDI_INPUT_DRIVER_PARAMETER INFO
548 - fixed possible compilation error when sqlite is not present
549 - fixed orphaned pointers when setting maximum voices limit (bug #118)
550 - fixed crash when changing the audio output device of a sampler
551 channel with loaded instrument and start playing notes
552 - fixed endless loop in Engine::SuspendAll() (bug #120)
553 - fixed a low-level atomic load function that was broken on 64-bit
554 PowerPC, which probably could cause crashes on that platform
555 - fixed a memory management error which could cause a crash when a
556 plugin was unloaded
557 - bugfix: two private structs had the same name, which could cause
558 problems if the linker chose the wrong constructor
559 - fixed low-level ConditionServer usage bug that caused lockups on
560 Windows
561
562
563 Version 0.5.1 (6 December 2007)
564
565 * packaging changes:
566 - added autoconf checks for pthread library
567 - added autoconf check for pthread bug found on certain NPTL-enabled
568 glibc versions (see Gentoo bug report #194076)
569 - added autoconf checks for MS Windows
570
571 * general changes:
572 - bugfix: the thread used by an editor plugin didn't die when the
573 editor closed
574 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
575 out all the space. operator--() did not apply size_mask after
576 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
577 order to avoid problems with the _NonVolatileReader functions.
578 - bugfix: Stream.h: added a missing divide by BytesPerSample in
579 GetWriteSpace(). Since this function is currently only used in
580 the stream's qsort() compare function, it didn't trigger any
581 bugs.
582 - Resampler.h, Synthesizer.h: cubic interpolation now works in
583 24bit mode too. Faster method to read 24bit words on little
584 endian machines (x86): replaced 3 byte reads + shifts with a 1
585 unaligned 32bit read and shift
586 - experimental support for MS Windows (MIDI input via MME, AUDIO
587 output via ASIO)
588 - made handling of SIGINT signal (Ctrl-C) a bit more robust
589 - support for monitoring the total number of active disk streams
590 (new LSCP commands: GET TOTAL_STREAM_COUNT,
591 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
592
593 * AUDIO driver:
594 - added Windows ASIO low latency audio driver
595
596 * MIDI driver:
597 - added MME Windows MIDI driver
598
599 * LSCP server:
600 - added support for Windows style path / filenames, however with
601 forward slash path separators instead of backslash
602 (i.e. "C:/foo/bar.gig")
603 - allow naughty liblscp to send non-string device parameters within
604 apostrophes as well
605 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
606 "LIST FILE INSTRUMENTS <file>" and
607 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
608 about an arbitrary instrument file on the system where the sampler is
609 running on
610
611 Version 0.5.0 (15 October 2007)
612
613 * packaging changes:
614 - config.h is not going to be installed along with liblinuxsampler's
615 API header files anymore
616 - only the API relevant header (and source) files will be exported to
617 the Doxygen API documentation (explicitly listed in Doxyfile.in)
618 - added completely new XCode project files for Mac OSX which is now
619 capable to execute our autoconf environment, thus no need anymore
620 to maintain the compile time configuration file (osx/version.h) for
621 OSX manually (patch by Toshi Nagata)
622 - fixed buggy boolean --enable-foo / --disable-foo configure script
623 parameters
624 - global.h now only covers global definitions that are needed for the
625 C++ API header files, all implementation internal global definitions
626 are now in global_private.h
627 - atomic.h is not exposed to the C++ API anymore
628 - no need to include config.h anymore for using LS's API header files
629 - fixed warnings in API doc generation
630
631 * general changes:
632 - replaced the old, confusing MIDI program change mechanism by a
633 flexible MIDI instrument mapper which allows to map arbitrary
634 (MIDI bank, MIDI program) pairs with arbitrary
635 (engine type, instrument file, file index) triplets which will be
636 loaded on the respective channel when such MIDI program change
637 messages arrive, beside that, each entry allows to define a life-time
638 strategy for the instrument, so the user can define whether the
639 instrument should i.e. be permanently loaded (to be able to switch
640 quickly among sounds) or i.e. loaded just on demand when the
641 respective program change arrives (to safe RAM space), as well as a
642 global volume factor for each entry, so the user can adjust the volume
643 dynamic of his mapped instrument collection without having to modify
644 the instrument files, also one can manage arbitrary amount of such
645 MIDI instrument maps and assign each sampler channel individually
646 a certain map, so that i.e. separation of normal instruments and
647 drumkits is possible
648 - new notification events for tracking changes to audio/MIDI devices,
649 MIDI instrument maps, MIDI instruments, FX sends, global volume.
650 - sampler was limited to load max. 200 instruments in the background
651 due to a constant size RingBuffer FIFO which is now replaced by a
652 dynamic (unlimited) size std::list FIFO
653 - added FX sends, these allow to route audio signals to arbitrary audio
654 output channels for being processed by external effect processors
655 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
656 controllers
657 - global (sampler wide) volume can now be controlled at runtime
658 - Implemented new, improved notification system
659 - fixed compilation errors regarding OSX
660 (patch by Toshi Nagata)
661 - implemented instruments database
662 - added support for escape sequences to the instruments database
663 - added highly experimental support for on-the-fly instrument editing
664 within the sampler's process (by using instrument editor plugins),
665 you'll notice the new "Registered instrument editors:" message on
666 startup, added a new LSCP command:
667 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
668 to spawn a matching instrument editor for the instrument on the
669 given sampler channel, the plugin path can be overridden at compile
670 time with ./configure --enable-plugin-dir=/some/dir
671 - added experimental code for synchronizing instrument editors hosted
672 in the sampler's process to safely edit instruments while playing
673 without a crash (hopefully) by either suspending single regions
674 wherever possible or if unavoidable whole engine(s)
675 - fixed several issues in fundamental "Thread" class: set scheduling
676 policy and priority on thread level, set a minimum stack size for
677 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
678 threads simply inherited properties of starting thread instead of
679 setting their own policy and priority
680 - minor fix in our automatic stack trace mechanism on crashes, the
681 main process did not wait for the stack trace process to finish
682 its output
683 - fixed some minor memory leaks
684 - reenabled assembly features support, at the moment only for
685 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
686 - minor assembly fix in x86 features detection (don't use the PIC
687 register, to avoid relocations in the text segment at runtime)
688 - POSIX callback functions of Thread.h are hidden
689
690 * MIDI driver:
691 - dispatch bank select (MSB and LSB) messages
692
693 * audio driver:
694 - the ALSA audio output driver parameters now reflect the correct
695 parameter value ranges for the respective selected sound card
696 (patch by Till Wimmer, a bit fixed and extended)
697
698 * Gigasampler format engine:
699 - if a filter is used and EG2 finishes before EG1, let the voice
700 die when EG2 has finished (this fixes a problem with clicks and
701 voice starvation for some gigs)
702 - playback is no longer disabled during instrument loading
703 - all notes playing on a channel that changes its instrument keep
704 playing with the old instrument until they get a note off
705 command
706 - EG fix: a release value of zero could cause noises or crash
707 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
708 - EG fine tuning: when attack is zero the EG starts at a level
709 above max sustain level, which means that there is a decay phase
710 even if sustain is 100%
711 - more EG fixes: the level could sometimes go below zero and cause
712 noises or crashes
713 - minor fix of EGDecay (patch by Toshi Nagata)
714 - fixed compiler error when --enable-override-filter-type was
715 supplied to the configure script (fixes #46)
716 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
717 instead of a fix value
718 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
719 127 (solo mode) only kill voices if the respective mode really
720 changed
721
722 * LSCP server:
723 - fixed compile time error for old Bison versions
724 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
725 - parser now supports extended ASCII character set
726 (up to ASCII code 255, i.e. includes now umlauts and accents)
727 - filename arguments in LSCP commands now allow to use escape
728 sequences, that is directly literal as one of: \', \", \\, \n, \r,
729 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
730 code value like \xf2) (fixes bug #24)
731 - the following LSCP commands now also support escape sequences for at
732 least one of their text-based parameters (i.e. name, description):
733 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
734 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
735 "SET DB_INSTRUMENT_DIRECTORY NAME",
736 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
737 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
738 "FIND DB_INSTRUMENT_DIRECTORIES"
739 - returns verbose syntax errors (line and column where syntax error
740 occured, the unexpected character and the actually expected, possible
741 character(s), the latter only if less than 5 possibilities)
742 - made sure that LSCP syntax is not affected by gigedit locale
743 settings
744 - bugfix regarding strings parameter lists: all comma separated lists
745 of strings were treated as being one string containing commas
746 (fixes #57)
747
748 * Bug fixes:
749 - fixed crash occurring on certain LSCP scripts (Bug 39)
750 - another thread safety fix for lscp "load engine" and "set
751 channel audio output device"
752 - fixed a crash which occurs when reassigning the same engine
753 on a sampler channel with connected MIDI device
754 - fixed a crash which occurs when changing the number of ports of a MIDI
755 device connected to a sampler channel to number less then or equal
756 to the index of the port to which the sampler channel is connected.
757 - The previous bindings were not been disconnected when altering
758 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
759 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
760 - The active stream/voice count statistic was incorrect.
761 - notification events were not been sent for some sampler
762 channel changes
763 - added default min and max values to restrict the number of allowed
764 audio output channels and MIDI input ports
765 - the connection to the PCM interface is now closed when destroying
766 an audio output device
767 - files with slash in their path or filename could not be loaded
768
769 * test cases:
770 - updated and fixed (haven't been touched in a while)
771
772 Version 0.4.0 (24 November 2006)
773
774 * packaging changes:
775 - changed deprecated copyright attribute to license; added ldconfig
776 to post-(un)install steps; added devel package for liblinuxsampler;
777 to linuxsampler.spec (RPM)
778 - install necessary development header files for allowing 3rd party
779 applications to link against liblinuxsampler
780 - liblinuxsampler's API documentation can be generated with 'make docs'
781 (Doxygen required)
782 - added benchmark to automatically detect the best triangle LFO
783 implementation (currently either an integer math solution or a
784 di-harmonic approximation), automatic detection can be overriden
785 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
786 configure script argument though (mandatory for cross-compilation)
787 - do not automatically pick optimized gcc flags if the user already
788 provided some on his own (as CXXFLAGS)
789 - added compile time option to disable processing of All-Notes-Off MIDI
790 messages
791 - added compile time options to allow disabling the various audio and
792 MIDI drivers
793 - fixed automatic GCC CPU switch detection on PPC
794 (patch by Ebrahim Mayat)
795
796 * Gigasampler format engine:
797 - extensive synthesis optimization
798 (reimplementation of EGs and LFO(s), removed synthesis parameter
799 prerendering and the synthesis parameter matrix in general, splitting
800 each audio fragment into subfragments now where each subfragment uses
801 constant pitch and filter coefficients. The volume coefficient is
802 linearly interpolated inside a subfragment, unless
803 --disable-interpolate-volume is set.)
804 - fine tuning of the EG modulation parameters
805 - improved filter cutoff calculation by adding support for the
806 following gig parameters: Cutoff freq (used when no cutoff
807 controller is defined), Control invert, Minimum cutoff, Velocity
808 curve and Velocity range. The keyboard tracking now scales
809 cutoff frequency instead of resonance.
810 - added support for gig parameter Resonance.
811 - fixed bug in sysex handling (patch by Juan Linietsky)
812 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
813 which can be overridden with --enable-global-attenuation
814 - EG fixes: made the length of "attack hold" stage more
815 accurate. Release stage can now start before attack stage
816 ends. Cancel release didn't work when sustain was zero. Attack
817 time now has a minimal value to prevent clicks.
818 - fixed pitch changes larger than one octave
819 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
820 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
821 all modes can be altered via standard GM messages, that is CC5 for
822 altering portamento time, CC65 for enabling / disabling portamento
823 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
824 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
825 parameter) and crossfade
826 - added support for the "attenuation controller threshold" gig
827 parameter
828 - added smoothing of volume changes caused by control change
829 messages
830 - sample loop parameters are now taken from the DimensionRegion
831 instead of the wave chunk
832 - fixed keyswitching for v3 gigs with a number of keyswitch splits
833 not equal to a power of two
834 - reimplementation of the filter algorithm. The new filter is more
835 accurate and supports all gig filter types, including bandreject
836 and lowpass turbo.
837 - real support for 24 bit samples - samples are not truncated to
838 16 bits anymore
839 - support for aftertouch (channel pressure, not polyphonic
840 aftertouch)
841 - LFO1 behaviour fixed (dampening from max volume instead of
842 amplifying from 0)
843
844 * LSCP server:
845 - fixed application exit on broken pipe error (fixes bug #20)
846 - fixed the notification messages delay due to lack of
847 network activity (fixes bug #26)
848 - fixed parser bug which occured on space(s) within device parameters
849 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
850
851 * audio driver:
852 - added aRts audio output driver (by no means RT safe)
853
854 * MIDI driver:
855 - fixed legacy sysex code which caused dispatching of MIDI SysEx
856 messages several times instead of once
857 - API extension for MIDI drivers which already supply exact time stamps
858 for events (i.e. for offline rendering based MIDI drivers)
859 - added checks for bad MIDI data
860
861 * linuxsampler application:
862 - show available sampler engine types on startup
863
864 * general changes:
865 - support for muting sampler channels and solo mode of the same, two new
866 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
867 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
868 introduced for this, the behavior is the same like on a mixer console
869 (patch by Grigor Iliev, a bit adjusted). Also added configure option
870 --enable-process-muted-channels which can be used to enable the
871 processing of muted channels.
872 - support for sostenuto pedal
873 - support for monitoring the total number of active voices
874 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
875 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
876 - fixed some memory management errors
877 - fixed some concurrency problems that could lead to crashes when
878 LSCP commands were executed
879 - fixed crash when instrument loading failed previously on the same
880 sampler channel (fixes bug #36)
881
882 Version 0.3.3 (15 July 2005)
883
884 * packaging changes:
885 - fixed compilation with gcc 4.0
886
887 * Gigasampler format engine:
888 - LFO preprocessing was performed even though the respective LFO was
889 disabled by the instrument patch (minor efficiency fix)
890 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
891 for volume ramp downs in the same fragment (needed for current voice
892 stealing implementation) then simply inform the user with a warning
893 about possible click sounds and reduce the volume ramp down
894 appropriately instead of cancelling the audio device connection
895
896 Version 0.3.2 (24 June 2005)
897
898 * packaging changes:
899 - updated autotools build files to compile on OS X
900 (conditional compilation of CoreMIDI and MidiShare drivers)
901 - hand-crafted assembly optimization code can be disabled with
902 './configure --disable-asm' (definitely not recommended)
903 - fixed 'make dist' rule to include all necessary files
904 - require automake (>= 1.5) for 'make -f Makefile.cvs'
905 (due to 'dist-bzip2' automake option)
906
907 * Gigasampler format engine:
908 - support for the gig parameters for "release velocity response" curves
909 - fine tuning of the EGADSR envelope
910 - volume of release triggered samples now depends on note-on velocity,
911 note length and gig parameter "release trigger decay" instead of
912 note-off velocity.
913 - revised voice stealing
914 (fixes crash and endless loop caused by voice stealing)
915 - don't reset scale tuning on instrument or audio output device change
916 - handle key group conflicts right at the beginning of each fragment
917 instead of when the respective voice is actually launched
