1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23            
24      * general changes:
25        - Refactoring: moved the independent code from
26          the Gigasampler format engine to base classes
27        - command line option '--profile' is currently disabled, since the
28          respective profiling code is currently broken
29        - Introduced support for optional environment variable
30          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
31          where the sampler shall look for instrument editor plugins
32          (patch by Luis Garrido, slightly modified).
33        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
34        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
35        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
36          note (in this implementation of the sampler its simply hard routed to
37          the 1st effect send of the sampler channel, no matter what the actual
38          effect type is)
39        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
40          note (in this implementation of the sampler its simply hard routed to
41          the 2nd effect send of the sampler channel, no matter what the actual
42          effect type is)
43        - implemented support for internal LADSPA effects
44        - raised limit of program change queue from 100 to 512
45          (as suggested by Alex Stone)

48        - added command line option --exec-after-init
49        - Introduced new C++ API method:
50          EngineChannel::InstrumentFileName(int index)
51          allowing to retrieve the whole list of files used for the loaded
52          instrument on an engine channel (a.k.a. part). Some GigaStudio
53          instruments for example are splitted over several files like
54          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
55        - Added new C++ API method Sampler::GetGlobalMaxVoices().
56        - Added new C++ API method Sampler::GetGlobalMaxStreams().

65          key
66    
67      * SFZ format engine:
68        - Initial implementation (not usable yet)

79          more compatible
80        - added support for trigger=release and rt_decay
81        - added support for off_mode=normal
82        - added support for random, seq_position, seq_length and volume

242          incorrectly set to two. This caused silence in Cubase 5.
243        - save engine type (gig, sfz or sf2) in plugin state
244        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
245          64 bit Windows
246        - AU: changed number of output channels from one stereo to 16
247          stereo

253          the plugin was loaded a second time (#174)
254        - plugin bugfix: instrument loading hang when the plugin was
255          loaded a second time (this time it's for Linux and Mac, previous
256          similar fix was for Windows)
257        - thread safety fixes for the instrument loading thread
258        - LV2: use the new lv2 package if present
259        - VST: try to open Fantasia automatically on Linux and Mac too (on
260          Linux, the Fantasia jar should be placed in <prefix>/share/java)
261        - VST: fixed crashes on Linux Ardour and EnergyXT
262        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
263          port and audio channel routing for DSSI plugins are now visible.
264        - LV2: use urid and atom extensions instead of deprecated uri-map
265          and event
266        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
267        - LV2: changed number of output channels to 16 stereo, just like
268          the VST and AU plugins
269        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
270        - LV2: made LV2 plugin buildable on Windows and Mac

272          sampler's internal MIDI instrument mapping system
273

275        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
276          the ALSA sequencer client name
277        - removed limit of maximum amount of MIDI ports per MIDI device, since
278          there is no reason for this limit
279        - MME: fixed memory handling bug found with cppcheck
280        - MME: removed compiler warning
281        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
282          which allows to retrieve the list of CoreMIDI clients / ports and to connect
283          to them a la JACK, via the usual sampler APIs
284        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
285          the driver will automatically connect to other CoreMIDI clients' ports
286          (e.g. external MIDI devices being attached to the Mac)
287    
288      * audio driver:
289        - ASIO driver fixes for newer gcc versions (fix from PortAudio)

332          channel to a different engine type
333        - fixed crash when deleting a sampler channel or changing engine
334          type while an instrument load was in progress
335        - bugfix: playing a note while changing the instrument could cause
336          a crash, or give "Handing back unknown region" error messages
337        - bugfix: calling SET VOICES (which Fantasia does on start and
338          refresh) could cause instruments to be unloaded
339        - Mac OS X: fixed name collision of enum in EffectControl and
340          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
341        - Mac OS X: fixed hanging threads
342        - Windows: disabled the previous thread fix on non-Mac systems, as
343          it caused hanging threads on Windows
344        - Fixed possible crashes due to corrupted MIDI/audio device list
345          after MIDI/audio device creation failure
346        - When creating MIDI instrument map entries with "PERSISTENT" type, the
347          instruments were uselessly precached with zero samples, however it still
348          took the full preloading time and on 1st program change the respective
349          instrument was completely reloaded again.
350        - fixed handling of rapid bank select and program change messages
351          sent to the same sampler channel (patch from the Open Octave
352          project, slightly adjusted)
353        - fixed crash when trying to create an effect instance with controls
354          which min and/or max values depend on the sample rate
355        - fixed bug #162
356        - bugfix: LADSPA_PATH was not evaluated correctly when containing
357          multiple paths (#165)
358        - thread safety fixes for the instrument loading thread
359        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
360          (#176)
361        - more thread safety fixes for the instrument loading thread
362        - sfz/sf2 engine: fixed crash when using small audio fragment size
363        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
364        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
365          introduced in previous fix)
366        - fixed crash when a channel received a program change while
367          playing a note in a key group
368        - fixed erroneous error message piping in VoiceBase.h
369          (labelled "Disk stream not available in time")
370    
371    Version 1.0.0 (31 July 2009)
372    
373      * packaging changes:
374        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
375          causing e.g. the libgig test to fail when
376          "./configure --disable-jack-driver" was used
377          (patch by Alexis Ballier)
378        - fixed compilation with gcc 4.3
379        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
380        - fixed configure so it detects x86_64 (#107)
381        - fixes for building with newer MinGW versions
382        - fix for building with bison 2.4 (#111)
383        - fixed building with libgig installed in a non-standard directory
384        - minor fix in configure for mmsystem.h detection on MinGW
385        - Windows: look for editor plugins and Fantasia using base
386          directory of liblinuxsampler dll (look in the same directory and one
387          directory above)
388        - configure script fix: removed unconditional use of SSE
389        - fixed building with sqlite installed in a non-standard directory
390        - when cross-compiling, don't try to create instruments.db
391        - fix for new mingw-w64 version, which has usleep
392    
393      * general changes:
394        - bugfix: on some POSIX systems instrument editor plugins refused to
395          load as we used a non-portable Linux specific struct field
396          (fixes bug #70, patch by Ronald Baljeu)
397        - fixed endless loop which occured when loading an instrument editor
398          plugin DLL on Windows systems failed
399        - fixed memory leaks that occurred when liblinuxsampler was unloaded
400        - optimized the SynchronizedConfig class so it doesn't wait
401          unnecessarily long after an update
402        - added support for notifying instrument editors on note-on / note-off
403          events (e.g. to highlight the pressed keys on the virtual keyboard
404          of gigedit)
405        - added support for triggering notes by instrument editors (see above)
406        - be verbose on DLL load errors (on Linux)
407        - fixed di-harmonic triangle LFO implementation (this LFO implementation
408          is only used by very few systems, most pick the int math
409          implementation, which is usually faster)
410        - fixes for audio drivers with varying buffer sizes
411        - experimental support for running LinuxSampler as a DSSI, LV2 and
412          VST plugin
413        - notification events for stream/voice count statistics are now sent
414          only when there are actual changes
415        - added memory ordering constraints to improve stability on
416          multi-core and multi-cpu systems
417        - maximum voices and disk streams can now be altered at runtime
418        - fixed CPU feature detection on x86_64 (maybe fixes #108)
419        - automatic stacktrace mechanism is now turned off by default and can
420          be switched on by command line option "--stacktrace" (the automatic
421          stacktrace mechanism seems to be broken on most systems at the moment)
422        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
423          a pointer to the launched InstrumentEditor object
424        - added optional 3rd party user data parameter for following
425          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
426          InstrumentEditor::Launch(),
427          InstrumentManager::LaunchInstrumentEditor()
428        - theoretical fix: made SynchronizedConfig follow C++0x memory
429          model more strictly
430        - fixes for using large audio device buffers
431        - Windows: add the installation directory to the DLL search path
432          when loading an editor plugin (solves problems with VST and
433          gigedit on systems with other GTK versions installed)
434    
435      * audio driver:
436        - removed the nonsense audio channel constraint (which was hard coded to
437          max. 100 audio channels) for most audio drivers
438        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
439          opposed to the LSCP specs
440        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
441          reflected the wrong value
442        - fixed a memory management bug in ASIO driver
443        - Makefile fix: JACK_CFLAGS wasn't used
444        - JACK: use jack_client_open instead of the deprecated
445          jack_client_new
446        - added (experimental) CoreAudio driver
447        - applied old fixes to the ASIO driver that were included in the
448          previous binary release but accidentally never committed to CVS
449          (fixes #117)
450        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
451          win64)
452        - VST: added support for sample rate and buffer size changes
453        - VST: close editor (Fantasia) when the VST is removed
454        - VST: avoid opening Fantasia more than once for each VST instance
455        - VST: export main function as "main" on Linux too (fix for
456          energyXT)
457        - VST: changed number of output channels from one stereo to 16
458          stereo
459        - added channel routing, fxsends and midi maps to the settings
460          stored in the plugin state
461        - performance optimization of AudioChannel::MixTo() and
462          AudioChannel::CopyTo() methods using GCC vector exensions
463          (if available)
464        - ASIO fixes: avoid initializing the device twice, avoid throwing
465          exception when getting parameters from a disconnected device
466    
467      * MIDI driver:
468        - added JACK MIDI driver
469        - dispatch bank select as ordinary CC as well, the user might seriously
470          want to (mis)use it for some purpose ("fixed" in all current MIDI
471          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
472        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
473          CoreMidi or AU
474        - fixed mingw-w64 compilation error in MME driver
475        - made program change handling in MIDI thread real-time safe by
476          moving the logic to a non-RT thread
477        - fixed minor memory leak in ALSA driver
478    
479      * instruments database:
480        - avoid time consuming samples scanning when adding instruments
481          to the instruments database
482        - added support for handling lost files in the instruments database
483        - Implemented option for adding instruments in separate directories
484          in the instruments database
485          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
486        - work-around for missing fnmatch function on Windows to make
487          instrument database compilable
488        - added instrument database support on Windows
489          works with both standalone mode and VST plugin.
490          the instruments DB file is located in
491          %USERPROFILE%\.linuxsampler\instruments.db which allows different
492          databases for each windows user
493          if no DB is present it automatically creates the .linuxsampler subdir
494          and then creates an empty DB
495        - fixed recursive import, which was broken on Windows
496    
497      * Gigasampler format engine:
498        - fixed a memory leak that could happen when a channel was deleted
499          while notes were playing
500        - made it possible to load an instrument even if the audio thread
501          isn't running
502        - added partial support for the "Controller Triggered" MIDI rule,
503          enough for piano gigs with pedal noise samples
504        - minor fix: only mark FX sends as being modified if really the
505          respective FX send MIDI controller was used
506        - added support for GM global device volume SysEx message
507          (can be selected at compile time to either apply globally to the
508          whole sampler [default] or only to the sampler channels that are
509          connected to the respective MIDI input port the SysEx message arrived
510          on)
511        - bugfix: notes triggered at position 0 in the audio buffer were
512          sometimes wrongly killed in the same buffer, causing no sound to
513          be played
514        - added support for chromatic / drumkit mode Roland GS Sysex message
515          which is usally used to switch a part between chromatic sounds and
516          drumkit sounds (as opposed to their common default setting of MIDI
517          part 10 being a drumkit part and all other ones chromatic parts), in
518          LS however one can switch between the first 16 MIDI instrument maps
519          defined for the sampler
520        - made it possible to create multiple sample channels even if the
521          audio thread isn't running
522        - fixed crash when removing channel with active voices (#116)
523        - bugfix: on sample reference changes (instrument editor), only
524          un-cache the respective sample if it's really not used by any
525          sampler engine anymore
526        - re-cache samples in case they were changed by an instrument editor,
527          e.g. when a sample was added while playing (#82)
528        - fixed hanging notes which occured when note-off event had the exact
529          same time stamp as the voice's note-on event and occured both in the
530          same audio fragment cycle (fixes bug #112)
531        - added support for the "fine tune" and "pitch bend range"
532          instrument-level gig parameters
533        - fixed minor artifacts in pitch bend handling
534        - added support for GS Reset SysEx message
535        - allow gig files to use unlimited downward pitch shifting
536        - added a limit check for upward pitch shifting
537        - bugfix: sometimes, when playing a note twice fast, the second
538          note was silent
539        - fixed crash happening when a pitch bend event arrived at the
540          same time a new instrument was loading
541    
542      * LSCP server:
543        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
544          react on MIDI data arriving on certain sampler channels (so far only
545          Note-On and Note-Off events are sent via this LSCP event)
546        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
547          react on MIDI data arriving on certain MIDI input devices (so far only
548          Note-On and Note-Off events are sent via this LSCP event)
549        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
550          SET DB_INSTRUMENT FILE_PATH
551        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
552          frontends to send MIDI messages to specific sampler channel
553        - added two additional fields to GET FILE INSTRUMENT INFO command -
554          KEY_BINDINGS and KEYSWITCH_BINDINGS
555        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
556          was incorrect
557        - Optimized the retrieval of the MIDI instrument mappings
558        - added new LSCP command "SET VOICES" to globally alter the maximum
559          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
560          be triggered respectively
561        - added new LSCP command "SET STREAMS" to globally alter the maximum
562          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
563          which will be triggered respectively
564        - bugfix: retry if "select" returns EINTR (this fixes a crash when
565          a gigedit file dialog is opened)
566        - close all connections when LSCPServer is deleted
567        - hard close of all sockets on exit
568        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
569          driver
570    
571      * Bug fixes:
572        - fixed a crash which occurs when removing a sampler channel waiting
573          to start instrument loading after another channel
574        - fixed a crash which occurs when removing a sampler channel with
575          instrument loading in progress (bug #113)
576        - fixed termination caused by uncaught exception when adding MIDI
577          instrument with PERSISTENT load mode
578        - fixed possible iterator invalidations when resetting the sampler
579        - fixed memory leaks when issuing the following LSCP commands:
580          GET AUDIO_OUTPUT_DRIVER INFO
581          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
582          GET MIDI_INPUT_DRIVER INFO
583          GET MIDI_INPUT_DRIVER_PARAMETER INFO
584        - fixed possible compilation error when sqlite is not present
585        - fixed orphaned pointers when setting maximum voices limit (bug #118)
586        - fixed crash when changing the audio output device of a sampler
587          channel with loaded instrument and start playing notes
588        - fixed endless loop in Engine::SuspendAll() (bug #120)
589        - fixed a low-level atomic load function that was broken on 64-bit
590          PowerPC, which probably could cause crashes on that platform
591        - fixed a memory management error which could cause a crash when a
592          plugin was unloaded
593        - bugfix: two private structs had the same name, which could cause
594          problems if the linker chose the wrong constructor
595        - fixed low-level ConditionServer usage bug that caused lockups on
596          Windows
597    
598    
599    Version 0.5.1 (6 December 2007)
600    
601      * packaging changes:
602        - added autoconf checks for pthread library
603        - added autoconf check for pthread bug found on certain NPTL-enabled
604          glibc versions (see Gentoo bug report #194076)
605        - added autoconf checks for MS Windows
606    
607      * general changes:
608        - bugfix: the thread used by an editor plugin didn't die when the
609          editor closed
610        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
611          out all the space. operator--() did not apply size_mask after
612          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
613          order to avoid problems with the _NonVolatileReader functions.
614        - bugfix: Stream.h: added a missing divide by BytesPerSample in
615          GetWriteSpace(). Since this function is currently only used in
616          the stream's qsort() compare function, it didn't trigger any
617          bugs.
618        - Resampler.h, Synthesizer.h: cubic interpolation now works in
619          24bit mode too. Faster method to read 24bit words on little
620          endian machines (x86): replaced 3 byte reads + shifts with a 1
621          unaligned 32bit read and shift
622        - experimental support for MS Windows (MIDI input via MME, AUDIO
623          output via ASIO)
624        - made handling of SIGINT signal (Ctrl-C) a bit more robust
625        - support for monitoring the total number of active disk streams
626          (new LSCP commands: GET TOTAL_STREAM_COUNT,
627          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
628    
629      * AUDIO driver:
630        - added Windows ASIO low latency audio driver
631    
632      * MIDI driver:
633        - added MME Windows MIDI driver
634    
635      * LSCP server:
636        - added support for Windows style path / filenames, however with
637          forward slash path separators instead of backslash
638          (i.e. "C:/foo/bar.gig")
639        - allow naughty liblscp to send non-string device parameters within
640          apostrophes as well
641        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
642          "LIST FILE INSTRUMENTS <file>" and
643          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
644          about an arbitrary instrument file on the system where the sampler is
645          running on
646    
647    Version 0.5.0 (15 October 2007)
648    
649      * packaging changes:
650        - config.h is not going to be installed along with liblinuxsampler's
651          API header files anymore
652        - only the API relevant header (and source) files will be exported to
653          the Doxygen API documentation (explicitly listed in Doxyfile.in)
654        - added completely new XCode project files for Mac OSX which is now
655          capable to execute our autoconf environment, thus no need anymore
656          to maintain the compile time configuration file (osx/version.h) for
657          OSX manually (patch by Toshi Nagata)
658        - fixed buggy boolean --enable-foo / --disable-foo configure script
659          parameters
660        - global.h now only covers global definitions that are needed for the
661          C++ API header files, all implementation internal global definitions
662          are now in global_private.h
663        - atomic.h is not exposed to the C++ API anymore
664        - no need to include config.h anymore for using LS's API header files
665        - fixed warnings in API doc generation
666    
667      * general changes:
668        - replaced the old, confusing MIDI program change mechanism by a
669          flexible MIDI instrument mapper which allows to map arbitrary
670          (MIDI bank, MIDI program) pairs with arbitrary
671          (engine type, instrument file, file index) triplets which will be
672          loaded on the respective channel when such MIDI program change
673          messages arrive, beside that, each entry allows to define a life-time
674          strategy for the instrument, so the user can define whether the
675          instrument should i.e. be permanently loaded (to be able to switch
676          quickly among sounds) or i.e. loaded just on demand when the
677          respective program change arrives (to safe RAM space), as well as a
678          global volume factor for each entry, so the user can adjust the volume
679          dynamic of his mapped instrument collection without having to modify
680          the instrument files, also one can manage arbitrary amount of such
681          MIDI instrument maps and assign each sampler channel individually
682          a certain map, so that i.e. separation of normal instruments and
683          drumkits is possible
684        - new notification events for tracking changes to audio/MIDI devices,
685          MIDI instrument maps, MIDI instruments, FX sends, global volume.
686        - sampler was limited to load max. 200 instruments in the background
687          due to a constant size RingBuffer FIFO which is now replaced by a
688          dynamic (unlimited) size std::list FIFO
689        - added FX sends, these allow to route audio signals to arbitrary audio
690          output channels for being processed by external effect processors
691          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
692          controllers
693        - global (sampler wide) volume can now be controlled at runtime
694        - Implemented new, improved notification system
695        - fixed compilation errors regarding OSX
696          (patch by Toshi Nagata)
697        - implemented instruments database
698        - added support for escape sequences to the instruments database
699        - added highly experimental support for on-the-fly instrument editing
700          within the sampler's process (by using instrument editor plugins),
701          you'll notice the new "Registered instrument editors:" message on
702          startup, added a new LSCP command:
703          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
704          to spawn a matching instrument editor for the instrument on the
705          given sampler channel, the plugin path can be overridden at compile
706          time with ./configure --enable-plugin-dir=/some/dir
707        - added experimental code for synchronizing instrument editors hosted
708          in the sampler's process to safely edit instruments while playing
709          without a crash (hopefully) by either suspending single regions
710          wherever possible or if unavoidable whole engine(s)
711        - fixed several issues in fundamental "Thread" class: set scheduling
712          policy and priority on thread level, set a minimum stack size for
713          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
714          threads simply inherited properties of starting thread instead of
715          setting their own policy and priority
716        - minor fix in our automatic stack trace mechanism on crashes, the
717          main process did not wait for the stack trace process to finish
718          its output
719        - fixed some minor memory leaks
720        - reenabled assembly features support, at the moment only for
721          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
722        - minor assembly fix in x86 features detection (don't use the PIC
723          register, to avoid relocations in the text segment at runtime)
724        - POSIX callback functions of Thread.h are hidden
725    
726      * MIDI driver:
727        - dispatch bank select (MSB and LSB) messages
728    
729      * audio driver:
730        - the ALSA audio output driver parameters now reflect the correct
731          parameter value ranges for the respective selected sound card
732          (patch by Till Wimmer, a bit fixed and extended)
733    
734      * Gigasampler format engine:
735        - if a filter is used and EG2 finishes before EG1, let the voice
736          die when EG2 has finished (this fixes a problem with clicks and
737          voice starvation for some gigs)
738        - playback is no longer disabled during instrument loading
739        - all notes playing on a channel that changes its instrument keep
740          playing with the old instrument until they get a note off
741          command
742        - EG fix: a release value of zero could cause noises or crash
743        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
744        - EG fine tuning: when attack is zero the EG starts at a level
745          above max sustain level, which means that there is a decay phase
746          even if sustain is 100%
747        - more EG fixes: the level could sometimes go below zero and cause
748          noises or crashes
749        - minor fix of EGDecay (patch by Toshi Nagata)
750        - fixed compiler error when --enable-override-filter-type was
751          supplied to the configure script (fixes #46)
752        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
753          instead of a fix value
754        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
755          127 (solo mode) only kill voices if the respective mode really
756          changed
757    
758      * LSCP server:
759        - fixed compile time error for old Bison versions
760          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
761        - parser now supports extended ASCII character set
762          (up to ASCII code 255, i.e. includes now umlauts and accents)
763        - filename arguments in LSCP commands now allow to use escape
764          sequences, that is directly literal as one of: \', \", \\, \n, \r,
765          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
766          code value like \xf2) (fixes bug #24)
767        - the following LSCP commands now also support escape sequences for at
768          least one of their text-based parameters (i.e. name, description):
769          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
770          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
771          "SET DB_INSTRUMENT_DIRECTORY NAME",
772          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
773          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
774          "FIND DB_INSTRUMENT_DIRECTORIES"
775        - returns verbose syntax errors (line and column where syntax error
776          occured, the unexpected character and the actually expected, possible
777          character(s), the latter only if less than 5 possibilities)
778        - made sure that LSCP syntax is not affected by gigedit locale
779          settings
780        - bugfix regarding strings parameter lists: all comma separated lists
781          of strings were treated as being one string containing commas
782          (fixes #57)
783    
784      * Bug fixes:
785        - fixed crash occurring on certain LSCP scripts (Bug 39)
786        - another thread safety fix for lscp "load engine" and "set
787          channel audio output device"
788        - fixed a crash which occurs when reassigning the same engine
789          on a sampler channel with connected MIDI device
790        - fixed a crash which occurs when changing the number of ports of a MIDI
791          device connected to a sampler channel to number less then or equal
792          to the index of the port to which the sampler channel is connected.
793        - The previous bindings were not been disconnected when altering
794          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
795          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
796        - The active stream/voice count statistic was incorrect.
797        - notification events were not been sent for some sampler
798          channel changes
799        - added default min and max values to restrict the number of allowed
800          audio output channels and MIDI input ports
801        - the connection to the PCM interface is now closed when destroying
802          an audio output device
803        - files with slash in their path or filename could not be loaded
804    
805      * test cases:
806        - updated and fixed (haven't been touched in a while)
807    
808    Version 0.4.0 (24 November 2006)
809    
810      * packaging changes:
811        - changed deprecated copyright attribute to license; added ldconfig
812          to post-(un)install steps; added devel package for liblinuxsampler;
813          to linuxsampler.spec (RPM)
814        - install necessary development header files for allowing 3rd party
815          applications to link against liblinuxsampler
816        - liblinuxsampler's API documentation can be generated with 'make docs'
817          (Doxygen required)
818        - added benchmark to automatically detect the best triangle LFO
819          implementation (currently either an integer math solution or a
820          di-harmonic approximation), automatic detection can be overriden
821          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
822          configure script argument though (mandatory for cross-compilation)
823        - do not automatically pick optimized gcc flags if the user already
824          provided some on his own (as CXXFLAGS)
825        - added compile time option to disable processing of All-Notes-Off MIDI
826          messages
827        - added compile time options to allow disabling the various audio and
828          MIDI drivers
829        - fixed automatic GCC CPU switch detection on PPC
830          (patch by Ebrahim Mayat)
831    
832      * Gigasampler format engine:
833        - extensive synthesis optimization
834          (reimplementation of EGs and LFO(s), removed synthesis parameter
835          prerendering and the synthesis parameter matrix in general, splitting
836          each audio fragment into subfragments now where each subfragment uses
837          constant pitch and filter coefficients. The volume coefficient is
838          linearly interpolated inside a subfragment, unless
839          --disable-interpolate-volume is set.)
840        - fine tuning of the EG modulation parameters
841        - improved filter cutoff calculation by adding support for the
842          following gig parameters: Cutoff freq (used when no cutoff
843          controller is defined), Control invert, Minimum cutoff, Velocity
844          curve and Velocity range. The keyboard tracking now scales
845          cutoff frequency instead of resonance.
846        - added support for gig parameter Resonance.
847        - fixed bug in sysex handling (patch by Juan Linietsky)
848        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
849          which can be overridden with --enable-global-attenuation
850        - EG fixes: made the length of "attack hold" stage more
851          accurate. Release stage can now start before attack stage
852          ends. Cancel release didn't work when sustain was zero. Attack
853          time now has a minimal value to prevent clicks.
854        - fixed pitch changes larger than one octave
855        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
856        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
857          all modes can be altered via standard GM messages, that is CC5 for
858          altering portamento time, CC65 for enabling / disabling portamento
859          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
860        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
861          parameter) and crossfade
862        - added support for the "attenuation controller threshold" gig
863          parameter
864        - added smoothing of volume changes caused by control change
865          messages
866        - sample loop parameters are now taken from the DimensionRegion
867          instead of the wave chunk
868        - fixed keyswitching for v3 gigs with a number of keyswitch splits
869          not equal to a power of two
870        - reimplementation of the filter algorithm. The new filter is more
871          accurate and supports all gig filter types, including bandreject
872          and lowpass turbo.
873        - real support for 24 bit samples - samples are not truncated to
874          16 bits anymore
875        - support for aftertouch (channel pressure, not polyphonic
876          aftertouch)
877        - LFO1 behaviour fixed (dampening from max volume instead of
878          amplifying from 0)
879    
880      * LSCP server:
881        - fixed application exit on broken pipe error (fixes bug #20)
882        - fixed the notification messages delay due to lack of
883          network activity (fixes bug #26)
884        - fixed parser bug which occured on space(s) within device parameters
885          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
886    
887      * audio driver:
888        - added aRts audio output driver (by no means RT safe)
889    
890      * MIDI driver:
891        - fixed legacy sysex code which caused dispatching of MIDI SysEx
892          messages several times instead of once
893        - API extension for MIDI drivers which already supply exact time stamps
894          for events (i.e. for offline rendering based MIDI drivers)
895        - added checks for bad MIDI data
896    
897      * linuxsampler application:
898        - show available sampler engine types on startup
899    
900      * general changes:
901        - support for muting sampler channels and solo mode of the same, two new
902          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
903          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
904          introduced for this, the behavior is the same like on a mixer console
905          (patch by Grigor Iliev, a bit adjusted). Also added configure option
906          --enable-process-muted-channels which can be used to enable the
907          processing of muted channels.
908        - support for sostenuto pedal
909        - support for monitoring the total number of active voices
910          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
911          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
912        - fixed some memory management errors
913        - fixed some concurrency problems that could lead to crashes when
914          LSCP commands were executed
915        - fixed crash when instrument loading failed previously on the same
916          sampler channel (fixes bug #36)
917    
918    Version 0.3.3 (15 July 2005)
919    
920      * packaging changes:
921      - fixed compilation with gcc 4.0      - fixed compilation with gcc 4.0
922    
923    * Gigasampler format engine:    * Gigasampler format engine:
924      - LFO preprocessing was performed even though the respective LFO was      - LFO preprocessing was performed even though the respective LFO was
925        disabled by the instrument patch (minor efficiency fix)        disabled by the instrument patch (minor efficiency fix)
926        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
927          for volume ramp downs in the same fragment (needed for current voice
928          stealing implementation) then simply inform the user with a warning
929          about possible click sounds and reduce the volume ramp down
930          appropriately instead of cancelling the audio device connection
931
