1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
26    
27      * general changes:
28        - Refactoring: moved the independent code from
29          the Gigasampler format engine to base classes
30        - command line option '--profile' is currently disabled, since the
31          respective profiling code is currently broken
32        - Introduced support for optional environment variable
33          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34          where the sampler shall look for instrument editor plugins
35          (patch by Luis Garrido, slightly modified).
36        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39          note (in this implementation of the sampler its simply hard routed to
40          the 1st effect send of the sampler channel, no matter what the actual
41          effect type is)
42        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43          note (in this implementation of the sampler its simply hard routed to
44          the 2nd effect send of the sampler channel, no matter what the actual
45          effect type is)
46        - implemented support for internal LADSPA effects
47        - raised limit of program change queue from 100 to 512
48          (as suggested by Alex Stone)

51        - added command line option --exec-after-init
52        - Introduced new C++ API method:
53          EngineChannel::InstrumentFileName(int index)
54          allowing to retrieve the whole list of files used for the loaded
55          instrument on an engine channel (a.k.a. part). Some GigaStudio
56          instruments for example are splitted over several files like
57          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58        - Added new C++ API method Sampler::GetGlobalMaxVoices().
59        - Added new C++ API method Sampler::GetGlobalMaxStreams().
60        - Added new C++ API method Sampler::SetGlobalMaxVoices().
61        - Added new C++ API method Sampler::SetGlobalMaxStreams().
62        - Various "const" and "restrict" optimizations.

64          applying panning, instead of using two separate pan functions in
65          series (#182)
66    
67      * Gigasampler format engine:
68        - implemented the "round robin keyboard" dimension
69        - fixed round robin and random dimensions for cases when number of
70          dimension zones is not a power of two
71        - made round robin use a counter for each region instead of each
72          key
73        - bugfix: pitch LFO controller "internal+aftertouch" was broken
74        - bugfix: filter keyboard tracking was broken
75        - filter performance fix (an unnecessary copy was made of the
76          filter parameters in each sub fragment)
77        - handle special case when pan parameter in gig file has max or
78          min value
79        - Exclusive Groups: don't ever stop voices of the same note,
80          doesn't sound naturally with a drumkit
81    
82      * SFZ format engine:
83        - Initial implementation (not usable yet)
84        - added support for v2 multiple stage envelope generators
85        - added a fine-tuned v1 envelope generator instead of using the
86          one from the gig engine
87        - fixed memory leak and memory handling errors
88        - added support for trigger=first, trigger=legato and sw_previous
89        - allow non-numerical key values ("C#4" for example)

253          incorrectly set to two. This caused silence in Cubase 5.
254        - save engine type (gig, sfz or sf2) in plugin state
255        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
256          64 bit Windows
257        - AU: changed number of output channels from one stereo to 16
258          stereo

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

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

333        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
334          <effect-chain> <effect-chain-pos> <effect-instance>"
335        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
336          <effect-chain> <chain-pos>"
337        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
338          <fx_send_id> <effect_chain> <chain_pos>"
339        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
340        - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",
341          "SUBSCRIBE EFFECT_INSTANCE_INFO", "SUBSCRIBE SEND_EFFECT_CHAIN_COUNT",
342          "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
343    
344      * Bug fixes:
345        - Fixed crash which may occur when MIDI key + transpose is out of range
346        - minor valgrind fixes
347        - fixed crash which occurred when changing an already deployed sampler
348          channel to a different engine type
349        - fixed crash when deleting a sampler channel or changing engine
350          type while an instrument load was in progress
351        - bugfix: playing a note while changing the instrument could cause
352          a crash, or give "Handing back unknown region" error messages
353        - bugfix: calling SET VOICES (which Fantasia does on start and
354          refresh) could cause instruments to be unloaded
355        - Mac OS X: fixed name collision of enum in EffectControl and
356          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
357        - Mac OS X: fixed hanging threads
358        - Windows: disabled the previous thread fix on non-Mac systems, as
359          it caused hanging threads on Windows
360        - Fixed possible crashes due to corrupted MIDI/audio device list
361          after MIDI/audio device creation failure
362        - When creating MIDI instrument map entries with "PERSISTENT" type, the
363          instruments were uselessly precached with zero samples, however it still
364          took the full preloading time and on 1st program change the respective
365          instrument was completely reloaded again.
366        - fixed handling of rapid bank select and program change messages
367          sent to the same sampler channel (patch from the Open Octave
368          project, slightly adjusted)
369        - fixed crash when trying to create an effect instance with controls
370          which min and/or max values depend on the sample rate

378        - sfz/sf2 engine: fixed crash when using small audio fragment size
379        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
380        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
381          introduced in previous fix)
382        - fixed crash when a channel received a program change while
383          playing a note in a key group
384        - fixed erroneous error message piping in VoiceBase.h
385          (labelled "Disk stream not available in time")
386    
387    Version 1.0.0 (31 July 2009)
388    
389      * packaging changes:
390        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
391          causing e.g. the libgig test to fail when
392          "./configure --disable-jack-driver" was used
393          (patch by Alexis Ballier)
394        - fixed compilation with gcc 4.3
395        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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

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

745      * audio driver:
746        - the ALSA audio output driver parameters now reflect the correct
747          parameter value ranges for the respective selected sound card
748          (patch by Till Wimmer, a bit fixed and extended)

758      - EG fix: a release value of zero could cause noises or crash      - EG fix: a release value of zero could cause noises or crash
759      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)      - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
760        - EG fine tuning: when attack is zero the EG starts at a level
761          above max sustain level, which means that there is a decay phase
762          even if sustain is 100%
763        - more EG fixes: the level could sometimes go below zero and cause
764          noises or crashes
765        - minor fix of EGDecay (patch by Toshi Nagata)
766        - fixed compiler error when --enable-override-filter-type was
767          supplied to the configure script (fixes #46)
768        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
769          instead of a fix value
770        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
771          127 (solo mode) only kill voices if the respective mode really
772          changed
773    
774      * LSCP server:
775        - fixed compile time error for old Bison versions
776          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
777        - parser now supports extended ASCII character set
778          (up to ASCII code 255, i.e. includes now umlauts and accents)
779        - filename arguments in LSCP commands now allow to use escape
780          sequences, that is directly literal as one of: \', \", \\, \n, \r,
781          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
782          code value like \xf2) (fixes bug #24)
783        - the following LSCP commands now also support escape sequences for at
784          least one of their text-based parameters (i.e. name, description):
785          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
786          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
787          "SET DB_INSTRUMENT_DIRECTORY NAME",
788          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
789          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
790          "FIND DB_INSTRUMENT_DIRECTORIES"
791        - returns verbose syntax errors (line and column where syntax error
792          occured, the unexpected character and the actually expected, possible
793          character(s), the latter only if less than 5 possibilities)
794        - made sure that LSCP syntax is not affected by gigedit locale
795          settings
796        - bugfix regarding strings parameter lists: all comma separated lists
797          of strings were treated as being one string containing commas
798          (fixes #57)

801      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
802      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
803        channel audio output device"        channel audio output device"
804        - fixed a crash which occurs when reassigning the same engine
805          on a sampler channel with connected MIDI device
806        - fixed a crash which occurs when changing the number of ports of a MIDI
807          device connected to a sampler channel to number less then or equal
808          to the index of the port to which the sampler channel is connected.
809        - The previous bindings were not been disconnected when altering
810          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
811          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
812        - The active stream/voice count statistic was incorrect.
813        - notification events were not been sent for some sampler
814          channel changes
815        - added default min and max values to restrict the number of allowed
816          audio output channels and MIDI input ports
817        - the connection to the PCM interface is now closed when destroying
818          an audio output device
819        - files with slash in their path or filename could not be loaded
820
