31    
32      * general changes:
33        - Refactoring: moved the independent code from
34          the Gigasampler format engine to base classes
35        - command line option '--profile' is currently disabled, since the
36          respective profiling code is currently broken
37        - Introduced support for optional environment variable
38          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
39          where the sampler shall look for instrument editor plugins
40          (patch by Luis Garrido, slightly modified).
41        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
42        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
43        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
44          note (in this implementation of the sampler its simply hard routed to
45          the 1st effect send of the sampler channel, no matter what the actual
46          effect type is)
47        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
48          note (in this implementation of the sampler its simply hard routed to
49          the 2nd effect send of the sampler channel, no matter what the actual
50          effect type is)
51        - implemented support for internal LADSPA effects
52        - raised limit of program change queue from 100 to 512
53          (as suggested by Alex Stone)
54        - implemented sine LFO, pulse LFO and saw LFO
55        - experimental support for per voice equalization
56        - added command line option --exec-after-init
57        - Introduced new C++ API method:
58          EngineChannel::InstrumentFileName(int index)
59          allowing to retrieve the whole list of files used for the loaded
60          instrument on an engine channel (a.k.a. part). Some GigaStudio
61          instruments for example are splitted over several files like
62          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
63        - Added new C++ API method Sampler::GetGlobalMaxVoices().
64        - Added new C++ API method Sampler::GetGlobalMaxStreams().
65        - Added new C++ API method Sampler::SetGlobalMaxVoices().
66        - Added new C++ API method Sampler::SetGlobalMaxStreams().
67        - Various "const" and "restrict" optimizations.
68        - all engines: add pan CC value to instrument pan parameter before
69          applying panning, instead of using two separate pan functions in
70          series (#182)
71        - added a lock guard class for exception safe mutex handling and
72          used it everywhere appropriate
73        - Immediately apply scale tuning changes to active voices.
74        - Exposed scale tuning to C++ API (along to the already existing standard
75          SysEx way).
76        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
77          and broken for ppc64. (Seq_cst loads and stores are actually not
78          used in LS, so the bug wasn't noticable.)
79        - lsatomic.h: added ARMv7 support
80    
81      * Gigasampler format engine:
82        - implemented the "round robin keyboard" dimension
83        - fixed round robin and random dimensions for cases when number of
84          dimension zones is not a power of two
85        - made round robin use a counter for each region instead of each
86          key
87        - bugfix: pitch LFO controller "internal+aftertouch" was broken
88        - bugfix: filter keyboard tracking was broken
89        - filter performance fix (an unnecessary copy was made of the
90          filter parameters in each sub fragment)
91        - handle special case when pan parameter in gig file has max or
92          min value
93        - Exclusive Groups: don't ever stop voices of the same note,
94          doesn't sound naturally with a drumkit
95        - fixed EG1 modulation when attack or release is zero
96    
97      * SFZ format engine:
98        - Initial implementation (not usable yet)
99        - added support for v2 multiple stage envelope generators
100        - added a fine-tuned v1 envelope generator instead of using the
101          one from the gig engine
102        - fixed memory leak and memory handling errors
103        - added support for trigger=first, trigger=legato and sw_previous
104        - allow non-numerical key values ("C#4" for example)
105        - "key" opcode now sets pitch_keycenter too
106        - fixed error when unloading instrument with same sample used by
107          multiple regions
108        - added some opcode aliases, like loopmode for loop_mode, to be
109          more compatible
110        - added support for trigger=release and rt_decay
111        - added support for off_mode=normal

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

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

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

320        - Implemented missing handling of MIDI "running status".
321        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
322        - MME bugfix: driver wasn't closed properly
323    
324      * audio driver:
325        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
326        - JACK audio: react on sample rate changes.
327        - JACK audio: react on buffer size changes.
328        - JACK audio: jack_port_get_buffer() was cached and called outside
329          RT context.
330        - ASIO driver: removed compiler warnings
331    
332      * LSCP server:

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

406          introduced in previous fix)
407        - fixed crash when a channel received a program change while
408          playing a note in a key group
409        - fixed erroneous error message piping in VoiceBase.h
410          (labelled "Disk stream not available in time")
411        - Update effects on sample rate & period size changes (to avoid
412          crashes and noise on such transitions).
413    
414    Version 1.0.0 (31 July 2009)
415    
416      * packaging changes:
417        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
418          causing e.g. the libgig test to fail when
419          "./configure --disable-jack-driver" was used
420          (patch by Alexis Ballier)
421        - fixed compilation with gcc 4.3
422        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
423        - fixed configure so it detects x86_64 (#107)
424        - fixes for building with newer MinGW versions
425        - fix for building with bison 2.4 (#111)
426        - fixed building with libgig installed in a non-standard directory
427        - minor fix in configure for mmsystem.h detection on MinGW
428        - Windows: look for editor plugins and Fantasia using base
429          directory of liblinuxsampler dll (look in the same directory and one
430          directory above)
431        - configure script fix: removed unconditional use of SSE
432        - fixed building with sqlite installed in a non-standard directory
433        - when cross-compiling, don't try to create instruments.db
434        - fix for new mingw-w64 version, which has usleep
435    
436      * general changes:
437        - bugfix: on some POSIX systems instrument editor plugins refused to
438          load as we used a non-portable Linux specific struct field
439          (fixes bug #70, patch by Ronald Baljeu)
440        - fixed endless loop which occured when loading an instrument editor
441          plugin DLL on Windows systems failed
442        - fixed memory leaks that occurred when liblinuxsampler was unloaded
443        - optimized the SynchronizedConfig class so it doesn't wait
444          unnecessarily long after an update
445        - added support for notifying instrument editors on note-on / note-off
446          events (e.g. to highlight the pressed keys on the virtual keyboard
447          of gigedit)
448        - added support for triggering notes by instrument editors (see above)
449        - be verbose on DLL load errors (on Linux)
450        - fixed di-harmonic triangle LFO implementation (this LFO implementation
451          is only used by very few systems, most pick the int math
452          implementation, which is usually faster)
453        - fixes for audio drivers with varying buffer sizes
454        - experimental support for running LinuxSampler as a DSSI, LV2 and
455          VST plugin
456        - notification events for stream/voice count statistics are now sent
457          only when there are actual changes
458        - added memory ordering constraints to improve stability on
459          multi-core and multi-cpu systems
460        - maximum voices and disk streams can now be altered at runtime
461        - fixed CPU feature detection on x86_64 (maybe fixes #108)
462        - automatic stacktrace mechanism is now turned off by default and can
463          be switched on by command line option "--stacktrace" (the automatic
464          stacktrace mechanism seems to be broken on most systems at the moment)
465        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
466          a pointer to the launched InstrumentEditor object
467        - added optional 3rd party user data parameter for following
468          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
469          InstrumentEditor::Launch(),
470          InstrumentManager::LaunchInstrumentEditor()
471        - theoretical fix: made SynchronizedConfig follow C++0x memory
472          model more strictly
473        - fixes for using large audio device buffers
474        - Windows: add the installation directory to the DLL search path
475          when loading an editor plugin (solves problems with VST and
476          gigedit on systems with other GTK versions installed)
477    
478      * audio driver:
479        - removed the nonsense audio channel constraint (which was hard coded to
480          max. 100 audio channels) for most audio drivers
481        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
482          opposed to the LSCP specs
483        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
484          reflected the wrong value
485        - fixed a memory management bug in ASIO driver
486        - Makefile fix: JACK_CFLAGS wasn't used
487        - JACK: use jack_client_open instead of the deprecated
488          jack_client_new
489        - added (experimental) CoreAudio driver
490        - applied old fixes to the ASIO driver that were included in the
491          previous binary release but accidentally never committed to CVS
492          (fixes #117)
493        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
494          win64)
495        - VST: added support for sample rate and buffer size changes
496        - VST: close editor (Fantasia) when the VST is removed
497        - VST: avoid opening Fantasia more than once for each VST instance
498        - VST: export main function as "main" on Linux too (fix for
499          energyXT)
500        - VST: changed number of output channels from one stereo to 16
501          stereo
502        - added channel routing, fxsends and midi maps to the settings
503          stored in the plugin state
504        - performance optimization of AudioChannel::MixTo() and
505          AudioChannel::CopyTo() methods using GCC vector exensions
506          (if available)
507        - ASIO fixes: avoid initializing the device twice, avoid throwing
508          exception when getting parameters from a disconnected device
509    
510      * MIDI driver:
511        - added JACK MIDI driver
512        - dispatch bank select as ordinary CC as well, the user might seriously
513          want to (mis)use it for some purpose ("fixed" in all current MIDI
514          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
515        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
516          CoreMidi or AU
517        - fixed mingw-w64 compilation error in MME driver
518        - made program change handling in MIDI thread real-time safe by
519          moving the logic to a non-RT thread
520        - fixed minor memory leak in ALSA driver
521    
522      * instruments database:
523        - avoid time consuming samples scanning when adding instruments
524          to the instruments database
525        - added support for handling lost files in the instruments database
526        - Implemented option for adding instruments in separate directories
527          in the instruments database
528          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
529        - work-around for missing fnmatch function on Windows to make
530          instrument database compilable
531        - added instrument database support on Windows
532          works with both standalone mode and VST plugin.
533          the instruments DB file is located in
534          %USERPROFILE%\.linuxsampler\instruments.db which allows different
535          databases for each windows user
536          if no DB is present it automatically creates the .linuxsampler subdir
537          and then creates an empty DB
538        - fixed recursive import, which was broken on Windows
539    
540      * Gigasampler format engine:
541        - fixed a memory leak that could happen when a channel was deleted
542          while notes were playing
543        - made it possible to load an instrument even if the audio thread
544          isn't running
545        - added partial support for the "Controller Triggered" MIDI rule,
546          enough for piano gigs with pedal noise samples
547        - minor fix: only mark FX sends as being modified if really the
548          respective FX send MIDI controller was used
549        - added support for GM global device volume SysEx message
550          (can be selected at compile time to either apply globally to the
551          whole sampler [default] or only to the sampler channels that are
552          connected to the respective MIDI input port the SysEx message arrived
553          on)
554        - bugfix: notes triggered at position 0 in the audio buffer were
555          sometimes wrongly killed in the same buffer, causing no sound to
556          be played
557        - added support for chromatic / drumkit mode Roland GS Sysex message
558          which is usally used to switch a part between chromatic sounds and
559          drumkit sounds (as opposed to their common default setting of MIDI
560          part 10 being a drumkit part and all other ones chromatic parts), in
561          LS however one can switch between the first 16 MIDI instrument maps
562          defined for the sampler
563        - made it possible to create multiple sample channels even if the
564          audio thread isn't running
565        - fixed crash when removing channel with active voices (#116)
566        - bugfix: on sample reference changes (instrument editor), only
567          un-cache the respective sample if it's really not used by any
568          sampler engine anymore
569        - re-cache samples in case they were changed by an instrument editor,
570          e.g. when a sample was added while playing (#82)
571        - fixed hanging notes which occured when note-off event had the exact
572          same time stamp as the voice's note-on event and occured both in the
573          same audio fragment cycle (fixes bug #112)
574        - added support for the "fine tune" and "pitch bend range"
575          instrument-level gig parameters
576        - fixed minor artifacts in pitch bend handling
577        - added support for GS Reset SysEx message
578        - allow gig files to use unlimited downward pitch shifting
579        - added a limit check for upward pitch shifting
580        - bugfix: sometimes, when playing a note twice fast, the second
581          note was silent
582        - fixed crash happening when a pitch bend event arrived at the
583          same time a new instrument was loading
584    
585      * LSCP server:
586        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
587          react on MIDI data arriving on certain sampler channels (so far only
588          Note-On and Note-Off events are sent via this LSCP event)
589        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
590          react on MIDI data arriving on certain MIDI input devices (so far only
591          Note-On and Note-Off events are sent via this LSCP event)
592        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
593          SET DB_INSTRUMENT FILE_PATH
594        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
595          frontends to send MIDI messages to specific sampler channel
596        - added two additional fields to GET FILE INSTRUMENT INFO command -
597          KEY_BINDINGS and KEYSWITCH_BINDINGS
598        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
599          was incorrect
600        - Optimized the retrieval of the MIDI instrument mappings
601        - added new LSCP command "SET VOICES" to globally alter the maximum
602          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
603          be triggered respectively
604        - added new LSCP command "SET STREAMS" to globally alter the maximum
605          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
606          which will be triggered respectively
607        - bugfix: retry if "select" returns EINTR (this fixes a crash when
608          a gigedit file dialog is opened)
609        - close all connections when LSCPServer is deleted
610        - hard close of all sockets on exit
611        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
612          driver
613    
614      * Bug fixes:
615        - fixed a crash which occurs when removing a sampler channel waiting
616          to start instrument loading after another channel
617        - fixed a crash which occurs when removing a sampler channel with
618          instrument loading in progress (bug #113)
619        - fixed termination caused by uncaught exception when adding MIDI
620          instrument with PERSISTENT load mode
621        - fixed possible iterator invalidations when resetting the sampler
622        - fixed memory leaks when issuing the following LSCP commands:
623          GET AUDIO_OUTPUT_DRIVER INFO
624          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
625          GET MIDI_INPUT_DRIVER INFO
626          GET MIDI_INPUT_DRIVER_PARAMETER INFO
627        - fixed possible compilation error when sqlite is not present
628        - fixed orphaned pointers when setting maximum voices limit (bug #118)
629        - fixed crash when changing the audio output device of a sampler
630          channel with loaded instrument and start playing notes
631        - fixed endless loop in Engine::SuspendAll() (bug #120)
632        - fixed a low-level atomic load function that was broken on 64-bit
633          PowerPC, which probably could cause crashes on that platform
634        - fixed a memory management error which could cause a crash when a
635          plugin was unloaded
636        - bugfix: two private structs had the same name, which could cause
637          problems if the linker chose the wrong constructor
638        - fixed low-level ConditionServer usage bug that caused lockups on
639          Windows
640    
641    
642    Version 0.5.1 (6 December 2007)
643    
644      * packaging changes:
645        - added autoconf checks for pthread library
646        - added autoconf check for pthread bug found on certain NPTL-enabled
647          glibc versions (see Gentoo bug report #194076)
648        - added autoconf checks for MS Windows
649    
650      * general changes:
651        - bugfix: the thread used by an editor plugin didn't die when the
652          editor closed
653        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
654          out all the space. operator--() did not apply size_mask after
655          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
656          order to avoid problems with the _NonVolatileReader functions.
657        - bugfix: Stream.h: added a missing divide by BytesPerSample in
658          GetWriteSpace(). Since this function is currently only used in
659          the stream's qsort() compare function, it didn't trigger any
660          bugs.
661        - Resampler.h, Synthesizer.h: cubic interpolation now works in
662          24bit mode too. Faster method to read 24bit words on little
663          endian machines (x86): replaced 3 byte reads + shifts with a 1
664          unaligned 32bit read and shift
665        - experimental support for MS Windows (MIDI input via MME, AUDIO
666          output via ASIO)
667        - made handling of SIGINT signal (Ctrl-C) a bit more robust
668        - support for monitoring the total number of active disk streams
669          (new LSCP commands: GET TOTAL_STREAM_COUNT,
670          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
671    
672      * AUDIO driver:
673        - added Windows ASIO low latency audio driver
674    
675      * MIDI driver:
676        - added MME Windows MIDI driver
677    
678      * LSCP server:
679        - added support for Windows style path / filenames, however with
680          forward slash path separators instead of backslash
681          (i.e. "C:/foo/bar.gig")
682        - allow naughty liblscp to send non-string device parameters within
683          apostrophes as well
684        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
685          "LIST FILE INSTRUMENTS <file>" and
686          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
687          about an arbitrary instrument file on the system where the sampler is
688          running on
689    
690    Version 0.5.0 (15 October 2007)
691    
692      * packaging changes:
693        - config.h is not going to be installed along with liblinuxsampler's
694          API header files anymore
695      - only the API relevant header (and source) files will be exported to      - only the API relevant header (and source) files will be exported to
696        the Doxygen API documentation (explicitly listed in Doxyfile.in)        the Doxygen API documentation (explicitly listed in Doxyfile.in)
697        - added completely new XCode project files for Mac OSX which is now
698          capable to execute our autoconf environment, thus no need anymore
699          to maintain the compile time configuration file (osx/version.h) for
700          OSX manually (patch by Toshi Nagata)
701        - fixed buggy boolean --enable-foo / --disable-foo configure script
702          parameters
703        - global.h now only covers global definitions that are needed for the
704          C++ API header files, all implementation internal global definitions
705          are now in global_private.h
706        - atomic.h is not exposed to the C++ API anymore
707        - no need to include config.h anymore for using LS's API header files
708        - fixed warnings in API doc generation
709

742        - added highly experimental support for on-the-fly instrument editing
743          within the sampler's process (by using instrument editor plugins),
744          you'll notice the new "Registered instrument editors:" message on
745          startup, added a new LSCP command:
746          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
747          to spawn a matching instrument editor for the instrument on the
748          given sampler channel, the plugin path can be overridden at compile
749          time with ./configure --enable-plugin-dir=/some/dir
750        - added experimental code for synchronizing instrument editors hosted
751          in the sampler's process to safely edit instruments while playing
752          without a crash (hopefully) by either suspending single regions
753          wherever possible or if unavoidable whole engine(s)
754        - fixed several issues in fundamental "Thread" class: set scheduling
755          policy and priority on thread level, set a minimum stack size for
756          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
757          threads simply inherited properties of starting thread instead of
758          setting their own policy and priority
759        - minor fix in our automatic stack trace mechanism on crashes, the
760          main process did not wait for the stack trace process to finish
761          its output
762        - fixed some minor memory leaks
763        - reenabled assembly features support, at the moment only for
764          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
765        - minor assembly fix in x86 features detection (don't use the PIC
766          register, to avoid relocations in the text segment at runtime)
767        - POSIX callback functions of Thread.h are hidden
768

790        - more EG fixes: the level could sometimes go below zero and cause
791          noises or crashes
792        - minor fix of EGDecay (patch by Toshi Nagata)
793        - fixed compiler error when --enable-override-filter-type was
794          supplied to the configure script (fixes #46)
795        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
796          instead of a fix value
797        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
798          127 (solo mode) only kill voices if the respective mode really
799          changed
800    
801      * LSCP server:
802        - fixed compile time error for old Bison versions
803          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
804        - parser now supports extended ASCII character set
805          (up to ASCII code 255, i.e. includes now umlauts and accents)
806        - filename arguments in LSCP commands now allow to use escape
807          sequences, that is directly literal as one of: \', \", \\, \n, \r,
808          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
809          code value like \xf2) (fixes bug #24)
810        - the following LSCP commands now also support escape sequences for at
811          least one of their text-based parameters (i.e. name, description):
812          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
813          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
814          "SET DB_INSTRUMENT_DIRECTORY NAME",
815          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
816          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
817          "FIND DB_INSTRUMENT_DIRECTORIES"
818        - returns verbose syntax errors (line and column where syntax error
819          occured, the unexpected character and the actually expected, possible
820          character(s), the latter only if less than 5 possibilities)
821        - made sure that LSCP syntax is not affected by gigedit locale
822          settings
823        - bugfix regarding strings parameter lists: all comma separated lists
824          of strings were treated as being one string containing commas
825          (fixes #57)
826    
827    * Bug fixes:    * Bug fixes:
828      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
829      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
830        channel audio output device"        channel audio output device"
831        - fixed a crash which occurs when reassigning the same engine
832          on a sampler channel with connected MIDI device
833        - fixed a crash which occurs when changing the number of ports of a MIDI
834          device connected to a sampler channel to number less then or equal
835          to the index of the port to which the sampler channel is connected.
836        - The previous bindings were not been disconnected when altering
837          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
838          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
839        - The active stream/voice count statistic was incorrect.
840        - notification events were not been sent for some sampler
841          channel changes
842        - added default min and max values to restrict the number of allowed
843          audio output channels and MIDI input ports
844        - the connection to the PCM interface is now closed when destroying
845          an audio output device
846        - files with slash in their path or filename could not be loaded
847    
848      * test cases:
849        - updated and fixed (haven't been touched in a while)
