* fixed compilation with gcc 4.7

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 - fixed compilation with gcc 4.7
22
23 * general changes:
24 - Refactoring: moved the independent code from
25 the Gigasampler format engine to base classes
26 - command line option '--profile' is currently disabled, since the
27 respective profiling code is currently broken
28 - Introduced support for optional environment variable
29 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
30 where the sampler shall look for instrument editor plugins
31 (patch by Luis Garrido, slightly modified).
32 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
33 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
34 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
35 note (in this implementation of the sampler its simply hard routed to
36 the 1st effect send of the sampler channel, no matter what the actual
37 effect type is)
38 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
39 note (in this implementation of the sampler its simply hard routed to
40 the 2nd effect send of the sampler channel, no matter what the actual
41 effect type is)
42 - implemented support for internal LADSPA effects
43 - raised limit of program change queue from 100 to 512
44 (as suggested by Alex Stone)
45 - implemented sine LFO, pulse LFO and saw LFO
46 - experimental support for per voice equalization
47 - added command line option --exec-after-init
48 - Introduced new C++ API method:
49 EngineChannel::InstrumentFileName(int index)
50 allowing to retrieve the whole list of files used for the loaded
51 instrument on an engine channel (a.k.a. part). Some GigaStudio
52 instruments for example are splitted over several files like
53 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
54

56 - implemented the "round robin keyboard" dimension
57 - fixed round robin and random dimensions for cases when number of
58 dimension zones is not a power of two

309 - bugfix: calling SET VOICES (which Fantasia does on start and
310 refresh) could cause instruments to be unloaded
311 - Mac OS X: fixed name collision of enum in EffectControl and
312 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
313 - Mac OS X: fixed hanging threads
314 - Windows: disabled the previous thread fix on non-Mac systems, as
315 it caused hanging threads on Windows

317 after MIDI/audio device creation failure
318 - When creating MIDI instrument map entries with "PERSISTENT" type, the
319 instruments were uselessly precached with zero samples, however it still
320 took the full preloading time and on 1st program change the respective
321 instrument was completely reloaded again.
322 - fixed handling of rapid bank select and program change messages
323 sent to the same sampler channel (patch from the Open Octave
324 project, slightly adjusted)

341 "./configure --disable-jack-driver" was used
342 (patch by Alexis Ballier)
343 - fixed compilation with gcc 4.3
344 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

349 - minor fix in configure for mmsystem.h detection on MinGW
350 - Windows: look for editor plugins and Fantasia using base
351 directory of liblinuxsampler dll (look in the same directory and one
352 directory above)
353 - configure script fix: removed unconditional use of SSE
354 - fixed building with sqlite installed in a non-standard directory

357
358 * general changes:
359 - bugfix: on some POSIX systems instrument editor plugins refused to
360 load as we used a non-portable Linux specific struct field
361 (fixes bug #70, patch by Ronald Baljeu)
362 - fixed endless loop which occured when loading an instrument editor
363 plugin DLL on Windows systems failed
364 - fixed memory leaks that occurred when liblinuxsampler was unloaded
365 - optimized the SynchronizedConfig class so it doesn't wait
366 unnecessarily long after an update

368 events (e.g. to highlight the pressed keys on the virtual keyboard
369 of gigedit)
370 - added support for triggering notes by instrument editors (see above)
371 - be verbose on DLL load errors (on Linux)
372 - fixed di-harmonic triangle LFO implementation (this LFO implementation
373 is only used by very few systems, most pick the int math
374 implementation, which is usually faster)
375 - fixes for audio drivers with varying buffer sizes
376 - experimental support for running LinuxSampler as a DSSI, LV2 and
377 VST plugin
378 - notification events for stream/voice count statistics are now sent
379 only when there are actual changes

383 - fixed CPU feature detection on x86_64 (maybe fixes #108)
384 - automatic stacktrace mechanism is now turned off by default and can
385 be switched on by command line option "--stacktrace" (the automatic
386 stacktrace mechanism seems to be broken on most systems at the moment)
387 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
388 a pointer to the launched InstrumentEditor object
389 - added optional 3rd party user data parameter for following
390 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
391 InstrumentEditor::Launch(),
392 InstrumentManager::LaunchInstrumentEditor()
393 - theoretical fix: made SynchronizedConfig follow C++0x memory
394 model more strictly
395 - fixes for using large audio device buffers
396 - Windows: add the installation directory to the DLL search path
397 when loading an editor plugin (solves problems with VST and
398 gigedit on systems with other GTK versions installed)
399
400 * audio driver:
401 - removed the nonsense audio channel constraint (which was hard coded to
402 max. 100 audio channels) for most audio drivers
403 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
404 opposed to the LSCP specs
405 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
406 reflected the wrong value
407 - fixed a memory management bug in ASIO driver
408 - Makefile fix: JACK_CFLAGS wasn't used
409 - JACK: use jack_client_open instead of the deprecated
410 jack_client_new

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