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

29        - build fix: libsndfile compiler flags were missing in some
30          makefiles
31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback

34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37    
38      * general changes:
39        - Refactoring: moved the independent code from
40          the Gigasampler format engine to base classes
41        - command line option '--profile' is currently disabled, since the
42          respective profiling code is currently broken
43        - Introduced support for optional environment variable
44          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45          where the sampler shall look for instrument editor plugins
46          (patch by Luis Garrido, slightly modified).
47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512
59          (as suggested by Alex Stone)
60        - implemented sine LFO, pulse LFO and saw LFO
61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86    
87      * Gigasampler format engine:
88        - implemented the "round robin keyboard" dimension
89        - fixed round robin and random dimensions for cases when number of
90          dimension zones is not a power of two
91        - made round robin use a counter for each region instead of each
92          key
93        - bugfix: pitch LFO controller "internal+aftertouch" was broken
94        - bugfix: filter keyboard tracking was broken
95        - filter performance fix (an unnecessary copy was made of the
96          filter parameters in each sub fragment)
97        - handle special case when pan parameter in gig file has max or
98          min value
99        - Exclusive Groups: don't ever stop voices of the same note,
100          doesn't sound naturally with a drumkit
101        - fixed EG1 modulation when attack or release is zero
102    
103      * SFZ format engine:
104        - Initial implementation (not usable yet)
105        - added support for v2 multiple stage envelope generators
106        - added a fine-tuned v1 envelope generator instead of using the
107          one from the gig engine
108        - fixed memory leak and memory handling errors
109        - added support for trigger=first, trigger=legato and sw_previous
110        - allow non-numerical key values ("C#4" for example)
111        - "key" opcode now sets pitch_keycenter too
112        - fixed error when unloading instrument with same sample used by
113          multiple regions
114        - added some opcode aliases, like loopmode for loop_mode, to be
115          more compatible
116        - added support for trigger=release and rt_decay

273        - Listen to all interfaces on Mac OS X (INADDR_ANY)
274        - VST bugfix: If the host called resume() before and after
275          changing sample rate or block size, the number of channels was
276          incorrectly set to two. This caused silence in Cubase 5.
277        - save engine type (gig, sfz or sf2) in plugin state
278        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
279          64 bit Windows
280        - AU: changed number of output channels from one stereo to 16
281          stereo
282        - VST: made it possible to build the VST plugin for Mac

287          the plugin was loaded a second time (#174)
288        - plugin bugfix: instrument loading hang when the plugin was
289          loaded a second time (this time it's for Linux and Mac, previous
290          similar fix was for Windows)
291        - thread safety fixes for the instrument loading thread
292        - LV2: use the new lv2 package if present
293        - VST: try to open Fantasia automatically on Linux and Mac too (on
294          Linux, the Fantasia jar should be placed in <prefix>/share/java)
295        - VST: fixed crashes on Linux Ardour and EnergyXT
296        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
297          port and audio channel routing for DSSI plugins are now visible.
298        - LV2: use urid and atom extensions instead of deprecated uri-map
299          and event
300        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
301        - LV2: changed number of output channels to 16 stereo, just like
302          the VST and AU plugins
303        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
304        - LV2: made LV2 plugin buildable on Windows and Mac

310          the ALSA sequencer client name
311        - removed limit of maximum amount of MIDI ports per MIDI device, since
312          there is no reason for this limit
313        - MME: fixed memory handling bug found with cppcheck
314        - MME: removed compiler warning
315        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
316          which allows to retrieve the list of CoreMIDI clients / ports and to connect
317          to them a la JACK, via the usual sampler APIs
318        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
319          the driver will automatically connect to other CoreMIDI clients' ports
320          (e.g. external MIDI devices being attached to the Mac)
321        - added support for MIDI note on velocity filter
322        - CoreMIDI: fixed memory deallocation error
323        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

326        - Implemented missing handling of MIDI "running status".
327        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
328        - MME bugfix: driver wasn't closed properly
329    
330      * audio driver:
331        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
332        - JACK audio: react on sample rate changes.

376      * Bug fixes:
377        - Fixed crash which may occur when MIDI key + transpose is out of range
378        - minor valgrind fixes
379        - fixed crash which occurred when changing an already deployed sampler
380          channel to a different engine type
381        - fixed crash when deleting a sampler channel or changing engine
382          type while an instrument load was in progress
383        - bugfix: playing a note while changing the instrument could cause
384          a crash, or give "Handing back unknown region" error messages
385        - bugfix: calling SET VOICES (which Fantasia does on start and
386          refresh) could cause instruments to be unloaded
387        - Mac OS X: fixed name collision of enum in EffectControl and
388          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
389        - Mac OS X: fixed hanging threads
390        - Windows: disabled the previous thread fix on non-Mac systems, as
391          it caused hanging threads on Windows
392        - Fixed possible crashes due to corrupted MIDI/audio device list
393          after MIDI/audio device creation failure
394        - When creating MIDI instrument map entries with "PERSISTENT" type, the
395          instruments were uselessly precached with zero samples, however it still
396          took the full preloading time and on 1st program change the respective
397          instrument was completely reloaded again.
398        - fixed handling of rapid bank select and program change messages
399          sent to the same sampler channel (patch from the Open Octave
400          project, slightly adjusted)
401        - fixed crash when trying to create an effect instance with controls
402          which min and/or max values depend on the sample rate

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