3      * plugin changes:
4        - LV2 "state" extension support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21        - fixed compilation with gcc 4.7
22        - fixed configure script error with old autoconf versions
23        - lsatomic.h: use gcc provided atomic functions if building with
24          gcc 4.7 and C++11
25    
26      * general changes:
27        - Refactoring: moved the independent code from
28          the Gigasampler format engine to base classes
29        - command line option '--profile' is currently disabled, since the
30          respective profiling code is currently broken
31        - Introduced support for optional environment variable
32          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33          where the sampler shall look for instrument editor plugins
34          (patch by Luis Garrido, slightly modified).
35        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 1st effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42          note (in this implementation of the sampler its simply hard routed to
43          the 2nd effect send of the sampler channel, no matter what the actual
44          effect type is)
45        - implemented support for internal LADSPA effects
46        - raised limit of program change queue from 100 to 512
47          (as suggested by Alex Stone)
48        - implemented sine LFO, pulse LFO and saw LFO
49        - experimental support for per voice equalization
50        - added command line option --exec-after-init
51        - Introduced new C++ API method:
52          EngineChannel::InstrumentFileName(int index)
53          allowing to retrieve the whole list of files used for the loaded
54          instrument on an engine channel (a.k.a. part). Some GigaStudio
55          instruments for example are splitted over several files like
56          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57    
58      * Gigasampler format engine:
59        - implemented the "round robin keyboard" dimension
60        - fixed round robin and random dimensions for cases when number of
61          dimension zones is not a power of two
62        - made round robin use a counter for each region instead of each
63          key
64

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

82        - added support for amp_veltrack and amp_velcurve_N
83        - fine-tuned the default velocity curve
84        - added support for transpose
85        - fixed crash when using sw_down/up
86        - improved logic for sw_lokey/hikey/up/down/last
87        - added more v1 aliases to parser

249          the plugin was loaded a second time (#174)
250        - plugin bugfix: instrument loading hang when the plugin was
251          loaded a second time (this time it's for Linux and Mac, previous

253        - thread safety fixes for the instrument loading thread
254        - LV2: use the new lv2 package if present

257        - VST: fixed crashes on Linux Ardour and EnergyXT
258        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
259          port and audio channel routing for DSSI plugins are now visible.

309      * Bug fixes:
310        - Fixed crash which may occur when MIDI key + transpose is out of range
311        - minor valgrind fixes
312        - fixed crash which occurred when changing an already deployed sampler
313          channel to a different engine type
314        - fixed crash when deleting a sampler channel or changing engine
315          type while an instrument load was in progress
316        - bugfix: playing a note while changing the instrument could cause
317          a crash, or give "Handing back unknown region" error messages
318        - bugfix: calling SET VOICES (which Fantasia does on start and
319          refresh) could cause instruments to be unloaded
320        - Mac OS X: fixed name collision of enum in EffectControl and
321          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
322        - Mac OS X: fixed hanging threads
323        - Windows: disabled the previous thread fix on non-Mac systems, as
324          it caused hanging threads on Windows
325        - Fixed possible crashes due to corrupted MIDI/audio device list
326          after MIDI/audio device creation failure
327        - When creating MIDI instrument map entries with "PERSISTENT" type, the
328          instruments were uselessly precached with zero samples, however it still
329          took the full preloading time and on 1st program change the respective
330          instrument was completely reloaded again.
331        - fixed handling of rapid bank select and program change messages
332          sent to the same sampler channel (patch from the Open Octave
333          project, slightly adjusted)

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