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        - fixed configure script error with old autoconf versions
23        - lsatomic.h: use gcc provided atomic functions if building with
24          gcc 4.7 and C++11
25    
26      * general changes:
27        - Refactoring: moved the independent code from
28          the Gigasampler format engine to base classes
29        - command line option '--profile' is currently disabled, since the
30          respective profiling code is currently broken
31        - Introduced support for optional environment variable
32          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33          where the sampler shall look for instrument editor plugins
34          (patch by Luis Garrido, slightly modified).
35        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 1st effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42          note (in this implementation of the sampler its simply hard routed to
43          the 2nd effect send of the sampler channel, no matter what the actual
44          effect type is)
45        - implemented support for internal LADSPA effects
46        - raised limit of program change queue from 100 to 512
47          (as suggested by Alex Stone)
48        - implemented sine LFO, pulse LFO and saw LFO
49        - experimental support for per voice equalization
50        - added command line option --exec-after-init
51        - Introduced new C++ API method:
52          EngineChannel::InstrumentFileName(int index)
53          allowing to retrieve the whole list of files used for the loaded
54          instrument on an engine channel (a.k.a. part). Some GigaStudio
55          instruments for example are splitted over several files like
56          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57    
58      * Gigasampler format engine:
59        - implemented the "round robin keyboard" dimension
60        - fixed round robin and random dimensions for cases when number of
61          dimension zones is not a power of two
62        - made round robin use a counter for each region instead of each
63          key
64

71        - added support for trigger=first, trigger=legato and sw_previous
72        - allow non-numerical key values ("C#4" for example)
73        - "key" opcode now sets pitch_keycenter too
74        - fixed error when unloading instrument with same sample used by
75          multiple regions
76        - added some opcode aliases, like loopmode for loop_mode, to be
77          more compatible
78        - added support for trigger=release and rt_decay
79        - added support for off_mode=normal

82        - added support for amp_veltrack and amp_velcurve_N
83        - fine-tuned the default velocity curve
84        - added support for transpose
85        - fixed crash when using sw_down/up
86        - improved logic for sw_lokey/hikey/up/down/last
87        - added more v1 aliases to parser

307      * Bug fixes:
308        - Fixed crash which may occur when MIDI key + transpose is out of range
309        - minor valgrind fixes
310        - fixed crash which occurred when changing an already deployed sampler
311          channel to a different engine type
312        - fixed crash when deleting a sampler channel or changing engine
313          type while an instrument load was in progress
314        - bugfix: playing a note while changing the instrument could cause
315          a crash, or give "Handing back unknown region" error messages
316        - bugfix: calling SET VOICES (which Fantasia does on start and
317          refresh) could cause instruments to be unloaded
318        - Mac OS X: fixed name collision of enum in EffectControl and
319          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
320        - Mac OS X: fixed hanging threads

322          it caused hanging threads on Windows
323        - Fixed possible crashes due to corrupted MIDI/audio device list
324          after MIDI/audio device creation failure
325        - When creating MIDI instrument map entries with "PERSISTENT" type, the
326          instruments were uselessly precached with zero samples, however it still
327          took the full preloading time and on 1st program change the respective
328          instrument was completely reloaded again.
329        - fixed handling of rapid bank select and program change messages
330          sent to the same sampler channel (patch from the Open Octave
331          project, slightly adjusted)

333          which min and/or max values depend on the sample rate
334        - fixed bug #162
335        - bugfix: LADSPA_PATH was not evaluated correctly when containing
336          multiple paths (#165)
337        - thread safety fixes for the instrument loading thread
338        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
339          (#176)
340        - more thread safety fixes for the instrument loading thread
341        - sfz/sf2 engine: fixed crash when using small audio fragment size
342        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
343        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
344          introduced in previous fix)
345        - fixed crash when a channel received a program change while
346          playing a note in a key group
347    
348    Version 1.0.0 (31 July 2009)
349    
350      * packaging changes:
351        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
352          causing e.g. the libgig test to fail when
353          "./configure --disable-jack-driver" was used
354          (patch by Alexis Ballier)
355        - fixed compilation with gcc 4.3
356        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
357        - fixed configure so it detects x86_64 (#107)
358        - fixes for building with newer MinGW versions
359        - fix for building with bison 2.4 (#111)
360        - fixed building with libgig installed in a non-standard directory
361        - minor fix in configure for mmsystem.h detection on MinGW
362        - Windows: look for editor plugins and Fantasia using base
363          directory of liblinuxsampler dll (look in the same directory and one
364          directory above)
365        - configure script fix: removed unconditional use of SSE
366        - fixed building with sqlite installed in a non-standard directory
367        - when cross-compiling, don't try to create instruments.db
368        - fix for new mingw-w64 version, which has usleep
369    
370      * general changes:
371        - bugfix: on some POSIX systems instrument editor plugins refused to
372          load as we used a non-portable Linux specific struct field
373          (fixes bug #70, patch by Ronald Baljeu)
374        - fixed endless loop which occured when loading an instrument editor
375          plugin DLL on Windows systems failed
376        - fixed memory leaks that occurred when liblinuxsampler was unloaded
377        - optimized the SynchronizedConfig class so it doesn't wait
378          unnecessarily long after an update
379        - added support for notifying instrument editors on note-on / note-off
380          events (e.g. to highlight the pressed keys on the virtual keyboard
381          of gigedit)
382        - added support for triggering notes by instrument editors (see above)
383        - be verbose on DLL load errors (on Linux)
384        - fixed di-harmonic triangle LFO implementation (this LFO implementation
385          is only used by very few systems, most pick the int math
386          implementation, which is usually faster)
387        - fixes for audio drivers with varying buffer sizes
388        - experimental support for running LinuxSampler as a DSSI, LV2 and
389          VST plugin
390        - notification events for stream/voice count statistics are now sent
391          only when there are actual changes
392        - added memory ordering constraints to improve stability on
393          multi-core and multi-cpu systems
394        - maximum voices and disk streams can now be altered at runtime
395        - fixed CPU feature detection on x86_64 (maybe fixes #108)
396        - automatic stacktrace mechanism is now turned off by default and can
397          be switched on by command line option "--stacktrace" (the automatic
398          stacktrace mechanism seems to be broken on most systems at the moment)
399        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
400          a pointer to the launched InstrumentEditor object
401        - added optional 3rd party user data parameter for following
402          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
403          InstrumentEditor::Launch(),
404          InstrumentManager::LaunchInstrumentEditor()
405        - theoretical fix: made SynchronizedConfig follow C++0x memory
406          model more strictly
407        - fixes for using large audio device buffers
408        - Windows: add the installation directory to the DLL search path
409          when loading an editor plugin (solves problems with VST and
410          gigedit on systems with other GTK versions installed)
411    
412      * audio driver:
413        - removed the nonsense audio channel constraint (which was hard coded to
414          max. 100 audio channels) for most audio drivers
415        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
416          opposed to the LSCP specs
417        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
418          reflected the wrong value
419        - fixed a memory management bug in ASIO driver
420        - Makefile fix: JACK_CFLAGS wasn't used
421        - JACK: use jack_client_open instead of the deprecated
422          jack_client_new
423        - added (experimental) CoreAudio driver
424        - applied old fixes to the ASIO driver that were included in the
425          previous binary release but accidentally never committed to CVS
426          (fixes #117)
427        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
428          win64)
429        - VST: added support for sample rate and buffer size changes
430        - VST: close editor (Fantasia) when the VST is removed
431        - VST: avoid opening Fantasia more than once for each VST instance
432        - VST: export main function as "main" on Linux too (fix for
433          energyXT)
434        - VST: changed number of output channels from one stereo to 16
435          stereo
436        - added channel routing, fxsends and midi maps to the settings
437          stored in the plugin state
438        - performance optimization of AudioChannel::MixTo() and
439          AudioChannel::CopyTo() methods using GCC vector exensions
440          (if available)
441        - ASIO fixes: avoid initializing the device twice, avoid throwing
442          exception when getting parameters from a disconnected device
443    
444      * MIDI driver:
445        - added JACK MIDI driver
446        - dispatch bank select as ordinary CC as well, the user might seriously
447          want to (mis)use it for some purpose ("fixed" in all current MIDI
448          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
449        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
450          CoreMidi or AU
451        - fixed mingw-w64 compilation error in MME driver
452        - made program change handling in MIDI thread real-time safe by
453          moving the logic to a non-RT thread
454        - fixed minor memory leak in ALSA driver
455    
456      * instruments database:
457        - avoid time consuming samples scanning when adding instruments
458          to the instruments database
459        - added support for handling lost files in the instruments database
460        - Implemented option for adding instruments in separate directories
461          in the instruments database
462          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
463        - work-around for missing fnmatch function on Windows to make
464          instrument database compilable
465        - added instrument database support on Windows
466          works with both standalone mode and VST plugin.
467          the instruments DB file is located in
468          %USERPROFILE%\.linuxsampler\instruments.db which allows different
469          databases for each windows user
470          if no DB is present it automatically creates the .linuxsampler subdir
471          and then creates an empty DB
472        - fixed recursive import, which was broken on Windows
473    
474      * Gigasampler format engine:
475        - fixed a memory leak that could happen when a channel was deleted
476          while notes were playing
477        - made it possible to load an instrument even if the audio thread
478          isn't running
479        - added partial support for the "Controller Triggered" MIDI rule,
480          enough for piano gigs with pedal noise samples
481        - minor fix: only mark FX sends as being modified if really the
482          respective FX send MIDI controller was used
483        - added support for GM global device volume SysEx message
484          (can be selected at compile time to either apply globally to the
485          whole sampler [default] or only to the sampler channels that are
486          connected to the respective MIDI input port the SysEx message arrived
487          on)
488        - bugfix: notes triggered at position 0 in the audio buffer were
489          sometimes wrongly killed in the same buffer, causing no sound to
490          be played
491        - added support for chromatic / drumkit mode Roland GS Sysex message
492          which is usally used to switch a part between chromatic sounds and
493          drumkit sounds (as opposed to their common default setting of MIDI
494          part 10 being a drumkit part and all other ones chromatic parts), in
495          LS however one can switch between the first 16 MIDI instrument maps
496          defined for the sampler
497        - made it possible to create multiple sample channels even if the
498          audio thread isn't running
499        - fixed crash when removing channel with active voices (#116)
500        - bugfix: on sample reference changes (instrument editor), only
501          un-cache the respective sample if it's really not used by any
502          sampler engine anymore
503        - re-cache samples in case they were changed by an instrument editor,
504          e.g. when a sample was added while playing (#82)
505        - fixed hanging notes which occured when note-off event had the exact
506          same time stamp as the voice's note-on event and occured both in the
507          same audio fragment cycle (fixes bug #112)
508        - added support for the "fine tune" and "pitch bend range"
509          instrument-level gig parameters
510        - fixed minor artifacts in pitch bend handling
511        - added support for GS Reset SysEx message
512        - allow gig files to use unlimited downward pitch shifting
513        - added a limit check for upward pitch shifting
514        - bugfix: sometimes, when playing a note twice fast, the second
515          note was silent
516        - fixed crash happening when a pitch bend event arrived at the
517          same time a new instrument was loading
518    
519      * LSCP server:
520        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
521          react on MIDI data arriving on certain sampler channels (so far only
522          Note-On and Note-Off events are sent via this LSCP event)
523        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
524          react on MIDI data arriving on certain MIDI input devices (so far only
525          Note-On and Note-Off events are sent via this LSCP event)
526        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
527          SET DB_INSTRUMENT FILE_PATH
528        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
529          frontends to send MIDI messages to specific sampler channel
530        - added two additional fields to GET FILE INSTRUMENT INFO command -
531          KEY_BINDINGS and KEYSWITCH_BINDINGS
532        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
533          was incorrect
534        - Optimized the retrieval of the MIDI instrument mappings
535        - added new LSCP command "SET VOICES" to globally alter the maximum
536          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
537          be triggered respectively
538        - added new LSCP command "SET STREAMS" to globally alter the maximum
539          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
540          which will be triggered respectively
541        - bugfix: retry if "select" returns EINTR (this fixes a crash when
542          a gigedit file dialog is opened)
543        - close all connections when LSCPServer is deleted
544        - hard close of all sockets on exit
545        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
546          driver
547    
548      * Bug fixes:
549        - fixed a crash which occurs when removing a sampler channel waiting
550          to start instrument loading after another channel
551        - fixed a crash which occurs when removing a sampler channel with
552          instrument loading in progress (bug #113)
553        - fixed termination caused by uncaught exception when adding MIDI
554          instrument with PERSISTENT load mode
555        - fixed possible iterator invalidations when resetting the sampler
556        - fixed memory leaks when issuing the following LSCP commands:
557          GET AUDIO_OUTPUT_DRIVER INFO
558          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
559          GET MIDI_INPUT_DRIVER INFO
560          GET MIDI_INPUT_DRIVER_PARAMETER INFO
561        - fixed possible compilation error when sqlite is not present
562        - fixed orphaned pointers when setting maximum voices limit (bug #118)
563        - fixed crash when changing the audio output device of a sampler
564          channel with loaded instrument and start playing notes
565        - fixed endless loop in Engine::SuspendAll() (bug #120)
566        - fixed a low-level atomic load function that was broken on 64-bit
567          PowerPC, which probably could cause crashes on that platform
568        - fixed a memory management error which could cause a crash when a
569          plugin was unloaded
570        - bugfix: two private structs had the same name, which could cause
571          problems if the linker chose the wrong constructor
572        - fixed low-level ConditionServer usage bug that caused lockups on
573          Windows
574    
575    
576    Version 0.5.1 (6 December 2007)
577    
578      * packaging changes:
579        - added autoconf checks for pthread library
580        - added autoconf check for pthread bug found on certain NPTL-enabled
581          glibc versions (see Gentoo bug report #194076)
582        - added autoconf checks for MS Windows
583    
584      * general changes:
585        - bugfix: the thread used by an editor plugin didn't die when the
586          editor closed
587        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
588          out all the space. operator--() did not apply size_mask after
589          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
590          order to avoid problems with the _NonVolatileReader functions.
591        - bugfix: Stream.h: added a missing divide by BytesPerSample in
592          GetWriteSpace(). Since this function is currently only used in
593          the stream's qsort() compare function, it didn't trigger any
594          bugs.
595        - Resampler.h, Synthesizer.h: cubic interpolation now works in
596          24bit mode too. Faster method to read 24bit words on little
597          endian machines (x86): replaced 3 byte reads + shifts with a 1
598          unaligned 32bit read and shift
599        - experimental support for MS Windows (MIDI input via MME, AUDIO
600          output via ASIO)
601        - made handling of SIGINT signal (Ctrl-C) a bit more robust
602        - support for monitoring the total number of active disk streams
603          (new LSCP commands: GET TOTAL_STREAM_COUNT,
604          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
605    
606      * AUDIO driver:
607        - added Windows ASIO low latency audio driver
608    
609      * MIDI driver:
610        - added MME Windows MIDI driver
611    
612      * LSCP server:
613        - added support for Windows style path / filenames, however with
614          forward slash path separators instead of backslash
615          (i.e. "C:/foo/bar.gig")
616        - allow naughty liblscp to send non-string device parameters within
617          apostrophes as well
618        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
619          "LIST FILE INSTRUMENTS <file>" and
620          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
621          about an arbitrary instrument file on the system where the sampler is
622          running on
623    
624    Version 0.5.0 (15 October 2007)
625    
626      * packaging changes:
627        - config.h is not going to be installed along with liblinuxsampler's
628          API header files anymore
629        - only the API relevant header (and source) files will be exported to
630          the Doxygen API documentation (explicitly listed in Doxyfile.in)
631        - added completely new XCode project files for Mac OSX which is now
632          capable to execute our autoconf environment, thus no need anymore
633          to maintain the compile time configuration file (osx/version.h) for
634          OSX manually (patch by Toshi Nagata)
635        - fixed buggy boolean --enable-foo / --disable-foo configure script
636          parameters
637        - global.h now only covers global definitions that are needed for the
638          C++ API header files, all implementation internal global definitions
639          are now in global_private.h
640        - atomic.h is not exposed to the C++ API anymore
641        - no need to include config.h anymore for using LS's API header files
642        - fixed warnings in API doc generation
643    
644      * general changes:
645        - replaced the old, confusing MIDI program change mechanism by a
646          flexible MIDI instrument mapper which allows to map arbitrary
647          (MIDI bank, MIDI program) pairs with arbitrary
648          (engine type, instrument file, file index) triplets which will be
649          loaded on the respective channel when such MIDI program change
650          messages arrive, beside that, each entry allows to define a life-time
651          strategy for the instrument, so the user can define whether the
652          instrument should i.e. be permanently loaded (to be able to switch
653          quickly among sounds) or i.e. loaded just on demand when the
654          respective program change arrives (to safe RAM space), as well as a
655          global volume factor for each entry, so the user can adjust the volume
656          dynamic of his mapped instrument collection without having to modify
657          the instrument files, also one can manage arbitrary amount of such
658          MIDI instrument maps and assign each sampler channel individually
659          a certain map, so that i.e. separation of normal instruments and
660          drumkits is possible
661        - new notification events for tracking changes to audio/MIDI devices,
662          MIDI instrument maps, MIDI instruments, FX sends, global volume.
663        - sampler was limited to load max. 200 instruments in the background
664          due to a constant size RingBuffer FIFO which is now replaced by a
665          dynamic (unlimited) size std::list FIFO
666        - added FX sends, these allow to route audio signals to arbitrary audio
667          output channels for being processed by external effect processors
668          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
669          controllers
670        - global (sampler wide) volume can now be controlled at runtime
671        - Implemented new, improved notification system
672        - fixed compilation errors regarding OSX
673          (patch by Toshi Nagata)
674        - implemented instruments database
675        - added support for escape sequences to the instruments database
676        - added highly experimental support for on-the-fly instrument editing
677          within the sampler's process (by using instrument editor plugins),
678          you'll notice the new "Registered instrument editors:" message on
679          startup, added a new LSCP command:
680          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
681          to spawn a matching instrument editor for the instrument on the
682          given sampler channel, the plugin path can be overridden at compile
683          time with ./configure --enable-plugin-dir=/some/dir
684        - added experimental code for synchronizing instrument editors hosted
685          in the sampler's process to safely edit instruments while playing
686          without a crash (hopefully) by either suspending single regions
687          wherever possible or if unavoidable whole engine(s)
688        - fixed several issues in fundamental "Thread" class: set scheduling
689          policy and priority on thread level, set a minimum stack size for
690          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
691          threads simply inherited properties of starting thread instead of
692          setting their own policy and priority
693        - minor fix in our automatic stack trace mechanism on crashes, the
694          main process did not wait for the stack trace process to finish
695          its output
696        - fixed some minor memory leaks
697        - reenabled assembly features support, at the moment only for
698          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
699        - minor assembly fix in x86 features detection (don't use the PIC
700          register, to avoid relocations in the text segment at runtime)
701        - POSIX callback functions of Thread.h are hidden
702    
703      * MIDI driver:
704        - dispatch bank select (MSB and LSB) messages
705    
706      * audio driver:
707        - the ALSA audio output driver parameters now reflect the correct
708          parameter value ranges for the respective selected sound card
709          (patch by Till Wimmer, a bit fixed and extended)
710    
711      * Gigasampler format engine:
712        - if a filter is used and EG2 finishes before EG1, let the voice
713          die when EG2 has finished (this fixes a problem with clicks and
714          voice starvation for some gigs)
715        - playback is no longer disabled during instrument loading
716        - all notes playing on a channel that changes its instrument keep
717          playing with the old instrument until they get a note off
718          command
719        - EG fix: a release value of zero could cause noises or crash
720        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
721        - EG fine tuning: when attack is zero the EG starts at a level
722          above max sustain level, which means that there is a decay phase
723          even if sustain is 100%
724        - more EG fixes: the level could sometimes go below zero and cause
725          noises or crashes
726        - minor fix of EGDecay (patch by Toshi Nagata)
727        - fixed compiler error when --enable-override-filter-type was
728          supplied to the configure script (fixes #46)
729        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
730          instead of a fix value
731        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
732          127 (solo mode) only kill voices if the respective mode really
733          changed
734    
735      * LSCP server:
736        - fixed compile time error for old Bison versions
737          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
738        - parser now supports extended ASCII character set
739          (up to ASCII code 255, i.e. includes now umlauts and accents)
740        - filename arguments in LSCP commands now allow to use escape
741          sequences, that is directly literal as one of: \', \", \\, \n, \r,
742          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
743          code value like \xf2) (fixes bug #24)
744        - the following LSCP commands now also support escape sequences for at
745          least one of their text-based parameters (i.e. name, description):
746          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
747          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
748          "SET DB_INSTRUMENT_DIRECTORY NAME",
749          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
750          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
751          "FIND DB_INSTRUMENT_DIRECTORIES"
752        - returns verbose syntax errors (line and column where syntax error
753          occured, the unexpected character and the actually expected, possible
754          character(s), the latter only if less than 5 possibilities)
755        - made sure that LSCP syntax is not affected by gigedit locale
756          settings
757        - bugfix regarding strings parameter lists: all comma separated lists
758          of strings were treated as being one string containing commas
759          (fixes #57)
760    
761      * Bug fixes:
762        - fixed crash occurring on certain LSCP scripts (Bug 39)
763        - another thread safety fix for lscp "load engine" and "set
764          channel audio output device"
765        - fixed a crash which occurs when reassigning the same engine
766          on a sampler channel with connected MIDI device
767        - fixed a crash which occurs when changing the number of ports of a MIDI
768          device connected to a sampler channel to number less then or equal
769          to the index of the port to which the sampler channel is connected.
770        - The previous bindings were not been disconnected when altering
771          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
772          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
773        - The active stream/voice count statistic was incorrect.
774        - notification events were not been sent for some sampler
775          channel changes
776        - added default min and max values to restrict the number of allowed
777          audio output channels and MIDI input ports
778        - the connection to the PCM interface is now closed when destroying
779          an audio output device
780        - files with slash in their path or filename could not be loaded
781    
782      * test cases:
783        - updated and fixed (haven't been touched in a while)
784    
785    Version 0.4.0 (24 November 2006)
786    
787      * packaging changes:
788        - changed deprecated copyright attribute to license; added ldconfig
789          to post-(un)install steps; added devel package for liblinuxsampler;
790          to linuxsampler.spec (RPM)
791        - install necessary development header files for allowing 3rd party
792          applications to link against liblinuxsampler
793        - liblinuxsampler's API documentation can be generated with 'make docs'
794          (Doxygen required)
795        - added benchmark to automatically detect the best triangle LFO
796          implementation (currently either an integer math solution or a
797          di-harmonic approximation), automatic detection can be overriden
798          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
799          configure script argument though (mandatory for cross-compilation)
800        - do not automatically pick optimized gcc flags if the user already
801          provided some on his own (as CXXFLAGS)
802        - added compile time option to disable processing of All-Notes-Off MIDI
803          messages
804        - added compile time options to allow disabling the various audio and
805          MIDI drivers
806        - fixed automatic GCC CPU switch detection on PPC
807          (patch by Ebrahim Mayat)
808    
809      * Gigasampler format engine:
810        - extensive synthesis optimization
811          (reimplementation of EGs and LFO(s), removed synthesis parameter
812          prerendering and the synthesis parameter matrix in general, splitting
813          each audio fragment into subfragments now where each subfragment uses
814          constant pitch and filter coefficients. The volume coefficient is
815          linearly interpolated inside a subfragment, unless
816          --disable-interpolate-volume is set.)
817        - fine tuning of the EG modulation parameters
818        - improved filter cutoff calculation by adding support for the
819          following gig parameters: Cutoff freq (used when no cutoff
820          controller is defined), Control invert, Minimum cutoff, Velocity
821          curve and Velocity range. The keyboard tracking now scales
822          cutoff frequency instead of resonance.
823        - added support for gig parameter Resonance.
824        - fixed bug in sysex handling (patch by Juan Linietsky)
825        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
826          which can be overridden with --enable-global-attenuation
827        - EG fixes: made the length of "attack hold" stage more
828          accurate. Release stage can now start before attack stage
829          ends. Cancel release didn't work when sustain was zero. Attack
830          time now has a minimal value to prevent clicks.
831        - fixed pitch changes larger than one octave
832        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
833        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
834          all modes can be altered via standard GM messages, that is CC5 for
835          altering portamento time, CC65 for enabling / disabling portamento
836          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
837        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
838          parameter) and crossfade
839        - added support for the "attenuation controller threshold" gig
840          parameter
841        - added smoothing of volume changes caused by control change
842          messages
843        - sample loop parameters are now taken from the DimensionRegion
844          instead of the wave chunk
845        - fixed keyswitching for v3 gigs with a number of keyswitch splits
846          not equal to a power of two
847        - reimplementation of the filter algorithm. The new filter is more
848          accurate and supports all gig filter types, including bandreject
849          and lowpass turbo.
850        - real support for 24 bit samples - samples are not truncated to
851          16 bits anymore
852        - support for aftertouch (channel pressure, not polyphonic
853          aftertouch)
854        - LFO1 behaviour fixed (dampening from max volume instead of
855          amplifying from 0)
856    
857      * LSCP server:
858        - fixed application exit on broken pipe error (fixes bug #20)
859        - fixed the notification messages delay due to lack of
860          network activity (fixes bug #26)
861        - fixed parser bug which occured on space(s) within device parameters
862          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
863    
864      * audio driver:
865        - added aRts audio output driver (by no means RT safe)
866    
867      * MIDI driver:
868        - fixed legacy sysex code which caused dispatching of MIDI SysEx
869          messages several times instead of once
870        - API extension for MIDI drivers which already supply exact time stamps
871          for events (i.e. for offline rendering based MIDI drivers)
872        - added checks for bad MIDI data
873    
874      * linuxsampler application:
875        - show available sampler engine types on startup
876    
877      * general changes:
878        - support for muting sampler channels and solo mode of the same, two new
879          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
880          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
881          introduced for this, the behavior is the same like on a mixer console
882          (patch by Grigor Iliev, a bit adjusted). Also added configure option
883          --enable-process-muted-channels which can be used to enable the
884          processing of muted channels.
885        - support for sostenuto pedal
886        - support for monitoring the total number of active voices
887          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
888          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
889        - fixed some memory management errors
890        - fixed some concurrency problems that could lead to crashes when
891          LSCP commands were executed
892        - fixed crash when instrument loading failed previously on the same
893          sampler channel (fixes bug #36)
894    
895    Version 0.3.3 (15 July 2005)
896    
897      * packaging changes:
898        - fixed compilation with gcc 4.0
899    
900      * Gigasampler format engine:
901        - LFO preprocessing was performed even though the respective LFO was
902          disabled by the instrument patch (minor efficiency fix)
903        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
904          for volume ramp downs in the same fragment (needed for current voice
905          stealing implementation) then simply inform the user with a warning
906          about possible click sounds and reduce the volume ramp down
907          appropriately instead of cancelling the audio device connection
908
