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        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
26        - removed usage of deprecated Automake variable INCLUDES
27    
28      * general changes:
29        - Refactoring: moved the independent code from
30          the Gigasampler format engine to base classes
31        - command line option '--profile' is currently disabled, since the
32          respective profiling code is currently broken
33        - Introduced support for optional environment variable
34          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
35          where the sampler shall look for instrument editor plugins
36          (patch by Luis Garrido, slightly modified).
37        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
38        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
39        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
40          note (in this implementation of the sampler its simply hard routed to
41          the 1st effect send of the sampler channel, no matter what the actual
42          effect type is)
43        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
44          note (in this implementation of the sampler its simply hard routed to
45          the 2nd effect send of the sampler channel, no matter what the actual
46          effect type is)
47        - implemented support for internal LADSPA effects
48        - raised limit of program change queue from 100 to 512
49          (as suggested by Alex Stone)

56          instrument on an engine channel (a.k.a. part). Some GigaStudio
57          instruments for example are splitted over several files like
58          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
59        - Added new C++ API method Sampler::GetGlobalMaxVoices().
60        - Added new C++ API method Sampler::GetGlobalMaxStreams().

69        - implemented the "round robin keyboard" dimension
70        - fixed round robin and random dimensions for cases when number of
71          dimension zones is not a power of two

73          key
74        - bugfix: pitch LFO controller "internal+aftertouch" was broken
75        - bugfix: filter keyboard tracking was broken
76        - filter performance fix (an unnecessary copy was made of the
77          filter parameters in each sub fragment)
78        - handle special case when pan parameter in gig file has max or
79          min value
80        - Exclusive Groups: don't ever stop voices of the same note,
81          doesn't sound naturally with a drumkit
82        - fixed EG1 modulation when attack or release is zero
83    
84      * SFZ format engine:
85        - Initial implementation (not usable yet)
86        - added support for v2 multiple stage envelope generators
87        - added a fine-tuned v1 envelope generator instead of using the

257          incorrectly set to two. This caused silence in Cubase 5.
258        - save engine type (gig, sfz or sf2) in plugin state
259        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
260          64 bit Windows

272        - thread safety fixes for the instrument loading thread
273        - LV2: use the new lv2 package if present
274        - VST: try to open Fantasia automatically on Linux and Mac too (on
275          Linux, the Fantasia jar should be placed in <prefix>/share/java)
276        - VST: fixed crashes on Linux Ardour and EnergyXT
277        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
278          port and audio channel routing for DSSI plugins are now visible.
279        - LV2: use urid and atom extensions instead of deprecated uri-map
280          and event
281        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
282        - LV2: changed number of output channels to 16 stereo, just like
283          the VST and AU plugins

293          there is no reason for this limit
294        - MME: fixed memory handling bug found with cppcheck
295        - MME: removed compiler warning
296        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
297          which allows to retrieve the list of CoreMIDI clients / ports and to connect
298          to them a la JACK, via the usual sampler APIs
299        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
300          the driver will automatically connect to other CoreMIDI clients' ports
301          (e.g. external MIDI devices being attached to the Mac)
302        - added support for MIDI note on velocity filter
303        - CoreMIDI: fixed memory deallocation error

315    
316      * LSCP server:

352    
353      * Bug fixes:
354        - Fixed crash which may occur when MIDI key + transpose is out of range
355        - minor valgrind fixes
356        - fixed crash which occurred when changing an already deployed sampler
357          channel to a different engine type
358        - fixed crash when deleting a sampler channel or changing engine
359          type while an instrument load was in progress
360        - bugfix: playing a note while changing the instrument could cause
361          a crash, or give "Handing back unknown region" error messages
362        - bugfix: calling SET VOICES (which Fantasia does on start and
363          refresh) could cause instruments to be unloaded
364        - Mac OS X: fixed name collision of enum in EffectControl and
365          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
366        - Mac OS X: fixed hanging threads
367        - Windows: disabled the previous thread fix on non-Mac systems, as
368          it caused hanging threads on Windows
369        - Fixed possible crashes due to corrupted MIDI/audio device list
370          after MIDI/audio device creation failure
371        - When creating MIDI instrument map entries with "PERSISTENT" type, the
372          instruments were uselessly precached with zero samples, however it still
373          took the full preloading time and on 1st program change the respective
374          instrument was completely reloaded again.
375        - fixed handling of rapid bank select and program change messages
376          sent to the same sampler channel (patch from the Open Octave
377          project, slightly adjusted)
378        - fixed crash when trying to create an effect instance with controls
379          which min and/or max values depend on the sample rate

387        - sfz/sf2 engine: fixed crash when using small audio fragment size
388        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
389        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
390          introduced in previous fix)
391        - fixed crash when a channel received a program change while
392          playing a note in a key group
393        - fixed erroneous error message piping in VoiceBase.h
394          (labelled "Disk stream not available in time")
395        - Update effects on sample rate & period size changes (to avoid
396          crashes and noise on such transitions).
397    
398    Version 1.0.0 (31 July 2009)
399    
400      * packaging changes:
401        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
402          causing e.g. the libgig test to fail when
403          "./configure --disable-jack-driver" was used
404          (patch by Alexis Ballier)
405        - fixed compilation with gcc 4.3
406        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
407        - fixed configure so it detects x86_64 (#107)
408        - fixes for building with newer MinGW versions
409        - fix for building with bison 2.4 (#111)
410        - fixed building with libgig installed in a non-standard directory
411        - minor fix in configure for mmsystem.h detection on MinGW
412        - Windows: look for editor plugins and Fantasia using base
413          directory of liblinuxsampler dll (look in the same directory and one
414          directory above)
415        - configure script fix: removed unconditional use of SSE
416        - fixed building with sqlite installed in a non-standard directory
417        - when cross-compiling, don't try to create instruments.db
418        - fix for new mingw-w64 version, which has usleep
419    
420      * general changes:
421        - bugfix: on some POSIX systems instrument editor plugins refused to
422          load as we used a non-portable Linux specific struct field
423          (fixes bug #70, patch by Ronald Baljeu)
424        - fixed endless loop which occured when loading an instrument editor
425          plugin DLL on Windows systems failed
426        - fixed memory leaks that occurred when liblinuxsampler was unloaded
427        - optimized the SynchronizedConfig class so it doesn't wait
428          unnecessarily long after an update
429        - added support for notifying instrument editors on note-on / note-off
430          events (e.g. to highlight the pressed keys on the virtual keyboard
431          of gigedit)
432        - added support for triggering notes by instrument editors (see above)
433        - be verbose on DLL load errors (on Linux)
434        - fixed di-harmonic triangle LFO implementation (this LFO implementation
435          is only used by very few systems, most pick the int math
436          implementation, which is usually faster)
437        - fixes for audio drivers with varying buffer sizes
438        - experimental support for running LinuxSampler as a DSSI, LV2 and
439          VST plugin
440        - notification events for stream/voice count statistics are now sent
441          only when there are actual changes
442        - added memory ordering constraints to improve stability on
443          multi-core and multi-cpu systems
444        - maximum voices and disk streams can now be altered at runtime
445        - fixed CPU feature detection on x86_64 (maybe fixes #108)
446        - automatic stacktrace mechanism is now turned off by default and can
447          be switched on by command line option "--stacktrace" (the automatic
448          stacktrace mechanism seems to be broken on most systems at the moment)
449        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
450          a pointer to the launched InstrumentEditor object
451        - added optional 3rd party user data parameter for following
452          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
453          InstrumentEditor::Launch(),
454          InstrumentManager::LaunchInstrumentEditor()
455        - theoretical fix: made SynchronizedConfig follow C++0x memory
456          model more strictly
457        - fixes for using large audio device buffers
458        - Windows: add the installation directory to the DLL search path
459          when loading an editor plugin (solves problems with VST and
460          gigedit on systems with other GTK versions installed)
461    
462      * audio driver:
463        - removed the nonsense audio channel constraint (which was hard coded to
464          max. 100 audio channels) for most audio drivers
465        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
466          opposed to the LSCP specs
467        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
468          reflected the wrong value
469        - fixed a memory management bug in ASIO driver
470        - Makefile fix: JACK_CFLAGS wasn't used
471        - JACK: use jack_client_open instead of the deprecated
472          jack_client_new
473        - added (experimental) CoreAudio driver
474        - applied old fixes to the ASIO driver that were included in the
475          previous binary release but accidentally never committed to CVS
476          (fixes #117)
477        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
478          win64)
479        - VST: added support for sample rate and buffer size changes
480        - VST: close editor (Fantasia) when the VST is removed
481        - VST: avoid opening Fantasia more than once for each VST instance
482        - VST: export main function as "main" on Linux too (fix for
483          energyXT)
484        - VST: changed number of output channels from one stereo to 16
485          stereo
486        - added channel routing, fxsends and midi maps to the settings
487          stored in the plugin state
488        - performance optimization of AudioChannel::MixTo() and
489          AudioChannel::CopyTo() methods using GCC vector exensions
490          (if available)
491        - ASIO fixes: avoid initializing the device twice, avoid throwing
492          exception when getting parameters from a disconnected device
493    
494      * MIDI driver:
495        - added JACK MIDI driver
496        - dispatch bank select as ordinary CC as well, the user might seriously
497          want to (mis)use it for some purpose ("fixed" in all current MIDI
498          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
499        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
500          CoreMidi or AU
501        - fixed mingw-w64 compilation error in MME driver
502        - made program change handling in MIDI thread real-time safe by
503          moving the logic to a non-RT thread
504        - fixed minor memory leak in ALSA driver
505    
506      * instruments database:
507        - avoid time consuming samples scanning when adding instruments
508          to the instruments database
509        - added support for handling lost files in the instruments database
510        - Implemented option for adding instruments in separate directories
511          in the instruments database
512          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
513        - work-around for missing fnmatch function on Windows to make
514          instrument database compilable
515        - added instrument database support on Windows
516          works with both standalone mode and VST plugin.
517          the instruments DB file is located in
518          %USERPROFILE%\.linuxsampler\instruments.db which allows different
519          databases for each windows user
520          if no DB is present it automatically creates the .linuxsampler subdir
521          and then creates an empty DB
522        - fixed recursive import, which was broken on Windows
523    
524      * Gigasampler format engine:
525        - fixed a memory leak that could happen when a channel was deleted
526          while notes were playing
527        - made it possible to load an instrument even if the audio thread
528          isn't running
529        - added partial support for the "Controller Triggered" MIDI rule,
530          enough for piano gigs with pedal noise samples
531        - minor fix: only mark FX sends as being modified if really the
532          respective FX send MIDI controller was used
533        - added support for GM global device volume SysEx message
534          (can be selected at compile time to either apply globally to the
535          whole sampler [default] or only to the sampler channels that are
536          connected to the respective MIDI input port the SysEx message arrived
537          on)
538        - bugfix: notes triggered at position 0 in the audio buffer were
539          sometimes wrongly killed in the same buffer, causing no sound to
540          be played
541        - added support for chromatic / drumkit mode Roland GS Sysex message
542          which is usally used to switch a part between chromatic sounds and
543          drumkit sounds (as opposed to their common default setting of MIDI
544          part 10 being a drumkit part and all other ones chromatic parts), in
545          LS however one can switch between the first 16 MIDI instrument maps
546          defined for the sampler
547        - made it possible to create multiple sample channels even if the
548          audio thread isn't running
549        - fixed crash when removing channel with active voices (#116)
550        - bugfix: on sample reference changes (instrument editor), only
551          un-cache the respective sample if it's really not used by any
552          sampler engine anymore
553        - re-cache samples in case they were changed by an instrument editor,
554          e.g. when a sample was added while playing (#82)
555        - fixed hanging notes which occured when note-off event had the exact
556          same time stamp as the voice's note-on event and occured both in the
557          same audio fragment cycle (fixes bug #112)
558        - added support for the "fine tune" and "pitch bend range"
559          instrument-level gig parameters
560        - fixed minor artifacts in pitch bend handling
561        - added support for GS Reset SysEx message
562        - allow gig files to use unlimited downward pitch shifting
563        - added a limit check for upward pitch shifting
564        - bugfix: sometimes, when playing a note twice fast, the second
565          note was silent
566        - fixed crash happening when a pitch bend event arrived at the
567          same time a new instrument was loading
568    
569      * LSCP server:
570        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
571          react on MIDI data arriving on certain sampler channels (so far only
572          Note-On and Note-Off events are sent via this LSCP event)
573        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
574          react on MIDI data arriving on certain MIDI input devices (so far only
575          Note-On and Note-Off events are sent via this LSCP event)
576        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
577          SET DB_INSTRUMENT FILE_PATH
578        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
579          frontends to send MIDI messages to specific sampler channel
580        - added two additional fields to GET FILE INSTRUMENT INFO command -
581          KEY_BINDINGS and KEYSWITCH_BINDINGS
582        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
583          was incorrect
584        - Optimized the retrieval of the MIDI instrument mappings
585        - added new LSCP command "SET VOICES" to globally alter the maximum
586          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
587          be triggered respectively
588        - added new LSCP command "SET STREAMS" to globally alter the maximum
589          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
590          which will be triggered respectively
591        - bugfix: retry if "select" returns EINTR (this fixes a crash when
592          a gigedit file dialog is opened)
593        - close all connections when LSCPServer is deleted
594        - hard close of all sockets on exit
595        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
596          driver
597    
598      * Bug fixes:
599        - fixed a crash which occurs when removing a sampler channel waiting
600          to start instrument loading after another channel
601        - fixed a crash which occurs when removing a sampler channel with
602          instrument loading in progress (bug #113)
603        - fixed termination caused by uncaught exception when adding MIDI
604          instrument with PERSISTENT load mode
605        - fixed possible iterator invalidations when resetting the sampler
606        - fixed memory leaks when issuing the following LSCP commands:
607          GET AUDIO_OUTPUT_DRIVER INFO
608          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
609          GET MIDI_INPUT_DRIVER INFO
610          GET MIDI_INPUT_DRIVER_PARAMETER INFO
611        - fixed possible compilation error when sqlite is not present
612        - fixed orphaned pointers when setting maximum voices limit (bug #118)
613        - fixed crash when changing the audio output device of a sampler
614          channel with loaded instrument and start playing notes
615        - fixed endless loop in Engine::SuspendAll() (bug #120)
616        - fixed a low-level atomic load function that was broken on 64-bit
617          PowerPC, which probably could cause crashes on that platform
618        - fixed a memory management error which could cause a crash when a
619          plugin was unloaded
620        - bugfix: two private structs had the same name, which could cause
621          problems if the linker chose the wrong constructor
622        - fixed low-level ConditionServer usage bug that caused lockups on
623          Windows
624    
625    
626    Version 0.5.1 (6 December 2007)
627    
628      * packaging changes:
629        - added autoconf checks for pthread library
630        - added autoconf check for pthread bug found on certain NPTL-enabled
631          glibc versions (see Gentoo bug report #194076)
632        - added autoconf checks for MS Windows
633    
634      * general changes:
635        - bugfix: the thread used by an editor plugin didn't die when the
636          editor closed
637        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
638          out all the space. operator--() did not apply size_mask after
639          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
640          order to avoid problems with the _NonVolatileReader functions.
641        - bugfix: Stream.h: added a missing divide by BytesPerSample in
642          GetWriteSpace(). Since this function is currently only used in
643          the stream's qsort() compare function, it didn't trigger any
644          bugs.
645        - Resampler.h, Synthesizer.h: cubic interpolation now works in
646          24bit mode too. Faster method to read 24bit words on little
647          endian machines (x86): replaced 3 byte reads + shifts with a 1
648          unaligned 32bit read and shift
649        - experimental support for MS Windows (MIDI input via MME, AUDIO
650          output via ASIO)
651        - made handling of SIGINT signal (Ctrl-C) a bit more robust
652        - support for monitoring the total number of active disk streams
653          (new LSCP commands: GET TOTAL_STREAM_COUNT,
654          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
655    
656      * AUDIO driver:
657        - added Windows ASIO low latency audio driver
658    
659      * MIDI driver:
660        - added MME Windows MIDI driver
661    
662      * LSCP server:
663        - added support for Windows style path / filenames, however with
664          forward slash path separators instead of backslash
665          (i.e. "C:/foo/bar.gig")
666        - allow naughty liblscp to send non-string device parameters within
667          apostrophes as well
668        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
669          "LIST FILE INSTRUMENTS <file>" and
670          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
671          about an arbitrary instrument file on the system where the sampler is
672          running on
673    
674    Version 0.5.0 (15 October 2007)
675    
676      * packaging changes:
677        - config.h is not going to be installed along with liblinuxsampler's
678          API header files anymore
679      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
680        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
681        - added completely new XCode project files for Mac OSX which is now
682          capable to execute our autoconf environment, thus no need anymore
683          to maintain the compile time configuration file (osx/version.h) for
684          OSX manually (patch by Toshi Nagata)
685        - fixed buggy boolean --enable-foo / --disable-foo configure script
686          parameters
687        - global.h now only covers global definitions that are needed for the
688          C++ API header files, all implementation internal global definitions
689          are now in global_private.h
690        - atomic.h is not exposed to the C++ API anymore
691        - no need to include config.h anymore for using LS's API header files
692        - fixed warnings in API doc generation
693    
694    * general changes:    * general changes:

720      - global (sampler wide) volume can now be controlled at runtime      - global (sampler wide) volume can now be controlled at runtime
721      - Implemented new, improved notification system      - Implemented new, improved notification system
722        - fixed compilation errors regarding OSX
723          (patch by Toshi Nagata)
724        - implemented instruments database
725        - added support for escape sequences to the instruments database
726        - added highly experimental support for on-the-fly instrument editing
727          within the sampler's process (by using instrument editor plugins),
728          you'll notice the new "Registered instrument editors:" message on
729          startup, added a new LSCP command:
730          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
731          to spawn a matching instrument editor for the instrument on the
732          given sampler channel, the plugin path can be overridden at compile
733          time with ./configure --enable-plugin-dir=/some/dir
734        - added experimental code for synchronizing instrument editors hosted
735          in the sampler's process to safely edit instruments while playing
736          without a crash (hopefully) by either suspending single regions
737          wherever possible or if unavoidable whole engine(s)
738        - fixed several issues in fundamental "Thread" class: set scheduling
739          policy and priority on thread level, set a minimum stack size for
740          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
741          threads simply inherited properties of starting thread instead of

743        - minor fix in our automatic stack trace mechanism on crashes, the
744          main process did not wait for the stack trace process to finish
745          its output
746        - fixed some minor memory leaks
747        - reenabled assembly features support, at the moment only for
748          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
749        - minor assembly fix in x86 features detection (don't use the PIC
750          register, to avoid relocations in the text segment at runtime)
751        - POSIX callback functions of Thread.h are hidden

776        - minor fix of EGDecay (patch by Toshi Nagata)
777        - fixed compiler error when --enable-override-filter-type was
778          supplied to the configure script (fixes #46)
779        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
780          instead of a fix value
781        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
782          127 (solo mode) only kill voices if the respective mode really
783          changed
784    
785      * LSCP server:
786        - fixed compile time error for old Bison versions
787          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
788        - parser now supports extended ASCII character set
789          (up to ASCII code 255, i.e. includes now umlauts and accents)
790        - filename arguments in LSCP commands now allow to use escape
791          sequences, that is directly literal as one of: \', \", \\, \n, \r,
792          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
793          code value like \xf2) (fixes bug #24)
794        - the following LSCP commands now also support escape sequences for at
795          least one of their text-based parameters (i.e. name, description):
796          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
797          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
798          "SET DB_INSTRUMENT_DIRECTORY NAME",
799          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
800          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
801          "FIND DB_INSTRUMENT_DIRECTORIES"
802        - returns verbose syntax errors (line and column where syntax error
803          occured, the unexpected character and the actually expected, possible
804          character(s), the latter only if less than 5 possibilities)
805        - made sure that LSCP syntax is not affected by gigedit locale
806          settings
807        - bugfix regarding strings parameter lists: all comma separated lists
808          of strings were treated as being one string containing commas
809          (fixes #57)

813      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
814        channel audio output device"        channel audio output device"
815        - fixed a crash which occurs when reassigning the same engine
816          on a sampler channel with connected MIDI device
817        - fixed a crash which occurs when changing the number of ports of a MIDI
818          device connected to a sampler channel to number less then or equal
819          to the index of the port to which the sampler channel is connected.
820        - The previous bindings were not been disconnected when altering
821          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
822          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
823        - The active stream/voice count statistic was incorrect.
824        - notification events were not been sent for some sampler
825          channel changes
826        - added default min and max values to restrict the number of allowed
827          audio output channels and MIDI input ports
828        - the connection to the PCM interface is now closed when destroying
829          an audio output device
830        - files with slash in their path or filename could not be loaded
831
