1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * 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().

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

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

98        - added support for loop_mode=one_shot
99        - fixed playback of 16 bit wav files on big endian CPUs

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

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

273          sampler's internal MIDI instrument mapping system
274

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

332        - fixed crash which occurred when changing an already deployed sampler
333          channel to a different engine type
334        - fixed crash when deleting a sampler channel or changing engine
335          type while an instrument load was in progress
336        - bugfix: playing a note while changing the instrument could cause
337          a crash, or give "Handing back unknown region" error messages
338        - bugfix: calling SET VOICES (which Fantasia does on start and
339          refresh) could cause instruments to be unloaded
340        - Mac OS X: fixed name collision of enum in EffectControl and
341          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
342        - Mac OS X: fixed hanging threads
343        - Windows: disabled the previous thread fix on non-Mac systems, as
344          it caused hanging threads on Windows
345        - Fixed possible crashes due to corrupted MIDI/audio device list
346          after MIDI/audio device creation failure
347        - When creating MIDI instrument map entries with "PERSISTENT" type, the
348          instruments were uselessly precached with zero samples, however it still
349          took the full preloading time and on 1st program change the respective
350          instrument was completely reloaded again.
351        - fixed handling of rapid bank select and program change messages
352          sent to the same sampler channel (patch from the Open Octave
353          project, slightly adjusted)
354        - fixed crash when trying to create an effect instance with controls
355          which min and/or max values depend on the sample rate
356        - fixed bug #162
357        - bugfix: LADSPA_PATH was not evaluated correctly when containing
358          multiple paths (#165)
359        - thread safety fixes for the instrument loading thread
360        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
361          (#176)
362        - more thread safety fixes for the instrument loading thread
363        - sfz/sf2 engine: fixed crash when using small audio fragment size
364        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
365        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
366          introduced in previous fix)
367        - fixed crash when a channel received a program change while
368          playing a note in a key group
369        - fixed erroneous error message piping in VoiceBase.h
370          (labelled "Disk stream not available in time")
371    
372    Version 1.0.0 (31 July 2009)
373    
374      * packaging changes:
375        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
376          causing e.g. the libgig test to fail when
377          "./configure --disable-jack-driver" was used
378          (patch by Alexis Ballier)
379        - fixed compilation with gcc 4.3
380        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
381        - fixed configure so it detects x86_64 (#107)
382        - fixes for building with newer MinGW versions
383        - fix for building with bison 2.4 (#111)
384        - fixed building with libgig installed in a non-standard directory
385        - minor fix in configure for mmsystem.h detection on MinGW
386        - Windows: look for editor plugins and Fantasia using base
387          directory of liblinuxsampler dll (look in the same directory and one
388          directory above)
389        - configure script fix: removed unconditional use of SSE
390        - fixed building with sqlite installed in a non-standard directory
391        - when cross-compiling, don't try to create instruments.db
392        - fix for new mingw-w64 version, which has usleep
393    
394      * general changes:
395        - bugfix: on some POSIX systems instrument editor plugins refused to
396          load as we used a non-portable Linux specific struct field
397          (fixes bug #70, patch by Ronald Baljeu)
398        - fixed endless loop which occured when loading an instrument editor
399          plugin DLL on Windows systems failed
400        - fixed memory leaks that occurred when liblinuxsampler was unloaded
401        - optimized the SynchronizedConfig class so it doesn't wait
402          unnecessarily long after an update
403        - added support for notifying instrument editors on note-on / note-off
404          events (e.g. to highlight the pressed keys on the virtual keyboard
405          of gigedit)
406        - added support for triggering notes by instrument editors (see above)
407        - be verbose on DLL load errors (on Linux)
408        - fixed di-harmonic triangle LFO implementation (this LFO implementation
409          is only used by very few systems, most pick the int math
410          implementation, which is usually faster)
411        - fixes for audio drivers with varying buffer sizes
412        - experimental support for running LinuxSampler as a DSSI, LV2 and
413          VST plugin
414        - notification events for stream/voice count statistics are now sent
415          only when there are actual changes
416        - added memory ordering constraints to improve stability on
417          multi-core and multi-cpu systems
418        - maximum voices and disk streams can now be altered at runtime
419        - fixed CPU feature detection on x86_64 (maybe fixes #108)
420        - automatic stacktrace mechanism is now turned off by default and can
421          be switched on by command line option "--stacktrace" (the automatic
422          stacktrace mechanism seems to be broken on most systems at the moment)
423        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
424          a pointer to the launched InstrumentEditor object
425        - added optional 3rd party user data parameter for following
426          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
427          InstrumentEditor::Launch(),
428          InstrumentManager::LaunchInstrumentEditor()
429        - theoretical fix: made SynchronizedConfig follow C++0x memory
430          model more strictly
431        - fixes for using large audio device buffers
432        - Windows: add the installation directory to the DLL search path
433          when loading an editor plugin (solves problems with VST and
434          gigedit on systems with other GTK versions installed)
435    
436      * audio driver:
437        - removed the nonsense audio channel constraint (which was hard coded to
438          max. 100 audio channels) for most audio drivers
439        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
440          opposed to the LSCP specs
441        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
442          reflected the wrong value
443        - fixed a memory management bug in ASIO driver
444        - Makefile fix: JACK_CFLAGS wasn't used
445        - JACK: use jack_client_open instead of the deprecated
446          jack_client_new
447        - added (experimental) CoreAudio driver
448        - applied old fixes to the ASIO driver that were included in the
449          previous binary release but accidentally never committed to CVS
450          (fixes #117)
451        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
452          win64)
453        - VST: added support for sample rate and buffer size changes
454        - VST: close editor (Fantasia) when the VST is removed
455        - VST: avoid opening Fantasia more than once for each VST instance
456        - VST: export main function as "main" on Linux too (fix for
457          energyXT)
458        - VST: changed number of output channels from one stereo to 16
459          stereo
460        - added channel routing, fxsends and midi maps to the settings
461          stored in the plugin state
462        - performance optimization of AudioChannel::MixTo() and
463          AudioChannel::CopyTo() methods using GCC vector exensions
464          (if available)
465        - ASIO fixes: avoid initializing the device twice, avoid throwing
466          exception when getting parameters from a disconnected device
467    
468      * MIDI driver:
469        - added JACK MIDI driver
470        - dispatch bank select as ordinary CC as well, the user might seriously
471          want to (mis)use it for some purpose ("fixed" in all current MIDI
472          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
473        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
474          CoreMidi or AU
475        - fixed mingw-w64 compilation error in MME driver
476        - made program change handling in MIDI thread real-time safe by
477          moving the logic to a non-RT thread
478        - fixed minor memory leak in ALSA driver
479    
480      * instruments database:
481        - avoid time consuming samples scanning when adding instruments
482          to the instruments database
483        - added support for handling lost files in the instruments database
484        - Implemented option for adding instruments in separate directories
485          in the instruments database
486          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
487        - work-around for missing fnmatch function on Windows to make
488          instrument database compilable
489        - added instrument database support on Windows
490          works with both standalone mode and VST plugin.
491          the instruments DB file is located in
492          %USERPROFILE%\.linuxsampler\instruments.db which allows different
493          databases for each windows user
494          if no DB is present it automatically creates the .linuxsampler subdir
495          and then creates an empty DB
496        - fixed recursive import, which was broken on Windows
497    
498      * Gigasampler format engine:
499        - fixed a memory leak that could happen when a channel was deleted
500          while notes were playing
501        - made it possible to load an instrument even if the audio thread
502          isn't running
503        - added partial support for the "Controller Triggered" MIDI rule,
504          enough for piano gigs with pedal noise samples
505        - minor fix: only mark FX sends as being modified if really the
506          respective FX send MIDI controller was used
507        - added support for GM global device volume SysEx message
508          (can be selected at compile time to either apply globally to the
509          whole sampler [default] or only to the sampler channels that are
510          connected to the respective MIDI input port the SysEx message arrived
511          on)
512        - bugfix: notes triggered at position 0 in the audio buffer were
513          sometimes wrongly killed in the same buffer, causing no sound to
514          be played
515        - added support for chromatic / drumkit mode Roland GS Sysex message
516          which is usally used to switch a part between chromatic sounds and
517          drumkit sounds (as opposed to their common default setting of MIDI
518          part 10 being a drumkit part and all other ones chromatic parts), in
519          LS however one can switch between the first 16 MIDI instrument maps
520          defined for the sampler
521        - made it possible to create multiple sample channels even if the
522          audio thread isn't running
523        - fixed crash when removing channel with active voices (#116)
524        - bugfix: on sample reference changes (instrument editor), only
525          un-cache the respective sample if it's really not used by any
526          sampler engine anymore
527        - re-cache samples in case they were changed by an instrument editor,
528          e.g. when a sample was added while playing (#82)
529        - fixed hanging notes which occured when note-off event had the exact
530          same time stamp as the voice's note-on event and occured both in the
531          same audio fragment cycle (fixes bug #112)
532        - added support for the "fine tune" and "pitch bend range"
533          instrument-level gig parameters
534        - fixed minor artifacts in pitch bend handling
535        - added support for GS Reset SysEx message
536        - allow gig files to use unlimited downward pitch shifting
537        - added a limit check for upward pitch shifting
538        - bugfix: sometimes, when playing a note twice fast, the second
539          note was silent
540        - fixed crash happening when a pitch bend event arrived at the
541          same time a new instrument was loading
542    
543      * LSCP server:
544        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
545          react on MIDI data arriving on certain sampler channels (so far only
546          Note-On and Note-Off events are sent via this LSCP event)
547        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
548          react on MIDI data arriving on certain MIDI input devices (so far only
549          Note-On and Note-Off events are sent via this LSCP event)
550        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
551          SET DB_INSTRUMENT FILE_PATH
552        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
553          frontends to send MIDI messages to specific sampler channel
554        - added two additional fields to GET FILE INSTRUMENT INFO command -
555          KEY_BINDINGS and KEYSWITCH_BINDINGS
556        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
557          was incorrect
558        - Optimized the retrieval of the MIDI instrument mappings
559        - added new LSCP command "SET VOICES" to globally alter the maximum
560          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
561          be triggered respectively
562        - added new LSCP command "SET STREAMS" to globally alter the maximum
563          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
564          which will be triggered respectively
565        - bugfix: retry if "select" returns EINTR (this fixes a crash when
566          a gigedit file dialog is opened)
567        - close all connections when LSCPServer is deleted
568        - hard close of all sockets on exit
569        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
570          driver
571    
572      * Bug fixes:
573        - fixed a crash which occurs when removing a sampler channel waiting
574          to start instrument loading after another channel
575        - fixed a crash which occurs when removing a sampler channel with
576          instrument loading in progress (bug #113)
577        - fixed termination caused by uncaught exception when adding MIDI
578          instrument with PERSISTENT load mode
579        - fixed possible iterator invalidations when resetting the sampler
580        - fixed memory leaks when issuing the following LSCP commands:
581          GET AUDIO_OUTPUT_DRIVER INFO
582          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
583          GET MIDI_INPUT_DRIVER INFO
584          GET MIDI_INPUT_DRIVER_PARAMETER INFO
585        - fixed possible compilation error when sqlite is not present
586        - fixed orphaned pointers when setting maximum voices limit (bug #118)
587        - fixed crash when changing the audio output device of a sampler
588          channel with loaded instrument and start playing notes
589        - fixed endless loop in Engine::SuspendAll() (bug #120)
590        - fixed a low-level atomic load function that was broken on 64-bit
591          PowerPC, which probably could cause crashes on that platform
592        - fixed a memory management error which could cause a crash when a
593          plugin was unloaded
594        - bugfix: two private structs had the same name, which could cause
595          problems if the linker chose the wrong constructor
596        - fixed low-level ConditionServer usage bug that caused lockups on
597          Windows
598    
599    
600    Version 0.5.1 (6 December 2007)
601    
602      * packaging changes:
603        - added autoconf checks for pthread library
604        - added autoconf check for pthread bug found on certain NPTL-enabled
605          glibc versions (see Gentoo bug report #194076)
606        - added autoconf checks for MS Windows
607    
608      * general changes:
609        - bugfix: the thread used by an editor plugin didn't die when the
610          editor closed
611        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
612          out all the space. operator--() did not apply size_mask after
613          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
614          order to avoid problems with the _NonVolatileReader functions.
615        - bugfix: Stream.h: added a missing divide by BytesPerSample in
616          GetWriteSpace(). Since this function is currently only used in
617          the stream's qsort() compare function, it didn't trigger any
618          bugs.
619        - Resampler.h, Synthesizer.h: cubic interpolation now works in
620          24bit mode too. Faster method to read 24bit words on little
621          endian machines (x86): replaced 3 byte reads + shifts with a 1
622          unaligned 32bit read and shift
623        - experimental support for MS Windows (MIDI input via MME, AUDIO
624          output via ASIO)
625        - made handling of SIGINT signal (Ctrl-C) a bit more robust
626        - support for monitoring the total number of active disk streams
627          (new LSCP commands: GET TOTAL_STREAM_COUNT,
628          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
629    
630      * AUDIO driver:
631        - added Windows ASIO low latency audio driver
632    
633      * MIDI driver:
634        - added MME Windows MIDI driver
635    
636      * LSCP server:
637        - added support for Windows style path / filenames, however with
638          forward slash path separators instead of backslash
639          (i.e. "C:/foo/bar.gig")
640        - allow naughty liblscp to send non-string device parameters within
641          apostrophes as well
642        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
643          "LIST FILE INSTRUMENTS <file>" and
644          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
645          about an arbitrary instrument file on the system where the sampler is
646          running on
647    
648    Version 0.5.0 (15 October 2007)
649    
650      * packaging changes:
651        - config.h is not going to be installed along with liblinuxsampler's
652          API header files anymore
653        - only the API relevant header (and source) files will be exported to
654          the Doxygen API documentation (explicitly listed in Doxyfile.in)
655        - added completely new XCode project files for Mac OSX which is now
656          capable to execute our autoconf environment, thus no need anymore
657          to maintain the compile time configuration file (osx/version.h) for
658          OSX manually (patch by Toshi Nagata)
659        - fixed buggy boolean --enable-foo / --disable-foo configure script
660          parameters
661        - global.h now only covers global definitions that are needed for the
662          C++ API header files, all implementation internal global definitions
663          are now in global_private.h
664        - atomic.h is not exposed to the C++ API anymore
665        - no need to include config.h anymore for using LS's API header files
666        - fixed warnings in API doc generation
667

694      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
695        - Implemented new, improved notification system
696        - fixed compilation errors regarding OSX
697          (patch by Toshi Nagata)
698        - implemented instruments database
699        - added support for escape sequences to the instruments database
700        - added highly experimental support for on-the-fly instrument editing
701          within the sampler's process (by using instrument editor plugins),
702          you'll notice the new "Registered instrument editors:" message on
703          startup, added a new LSCP command:
704          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
705          to spawn a matching instrument editor for the instrument on the
706          given sampler channel, the plugin path can be overridden at compile
707          time with ./configure --enable-plugin-dir=/some/dir
708        - added experimental code for synchronizing instrument editors hosted
709          in the sampler's process to safely edit instruments while playing
710          without a crash (hopefully) by either suspending single regions
711          wherever possible or if unavoidable whole engine(s)
712        - fixed several issues in fundamental "Thread" class: set scheduling
713          policy and priority on thread level, set a minimum stack size for
714          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
715          threads simply inherited properties of starting thread instead of
716          setting their own policy and priority
717        - minor fix in our automatic stack trace mechanism on crashes, the
718          main process did not wait for the stack trace process to finish
719          its output
720        - fixed some minor memory leaks
721        - reenabled assembly features support, at the moment only for
722          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
723        - minor assembly fix in x86 features detection (don't use the PIC
724          register, to avoid relocations in the text segment at runtime)
725        - POSIX callback functions of Thread.h are hidden
726

748        - more EG fixes: the level could sometimes go below zero and cause
749          noises or crashes
750        - minor fix of EGDecay (patch by Toshi Nagata)
751        - fixed compiler error when --enable-override-filter-type was
752          supplied to the configure script (fixes #46)
753        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
754          instead of a fix value
755        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
756          127 (solo mode) only kill voices if the respective mode really
757          changed

759      * LSCP server:
760        - fixed compile time error for old Bison versions
761          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
762        - parser now supports extended ASCII character set
763          (up to ASCII code 255, i.e. includes now umlauts and accents)
764        - filename arguments in LSCP commands now allow to use escape
765          sequences, that is directly literal as one of: \', \", \\, \n, \r,
766          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
767          code value like \xf2) (fixes bug #24)
768        - the following LSCP commands now also support escape sequences for at
769          least one of their text-based parameters (i.e. name, description):
770          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
771          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
772          "SET DB_INSTRUMENT_DIRECTORY NAME",
773          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
774          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
775          "FIND DB_INSTRUMENT_DIRECTORIES"
776        - returns verbose syntax errors (line and column where syntax error
777          occured, the unexpected character and the actually expected, possible
778          character(s), the latter only if less than 5 possibilities)
779        - made sure that LSCP syntax is not affected by gigedit locale
780          settings
781        - bugfix regarding strings parameter lists: all comma separated lists
782          of strings were treated as being one string containing commas

787      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
788        channel audio output device"        channel audio output device"
789        - fixed a crash which occurs when reassigning the same engine
790          on a sampler channel with connected MIDI device
791        - fixed a crash which occurs when changing the number of ports of a MIDI
792          device connected to a sampler channel to number less then or equal
793          to the index of the port to which the sampler channel is connected.
794        - The previous bindings were not been disconnected when altering
795          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
796          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
797        - The active stream/voice count statistic was incorrect.
798        - notification events were not been sent for some sampler
799          channel changes
800        - added default min and max values to restrict the number of allowed
801          audio output channels and MIDI input ports
802        - the connection to the PCM interface is now closed when destroying
803          an audio output device
804        - files with slash in their path or filename could not be loaded
