1  Version CVS HEAD (?)  Version CVS HEAD (?)
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
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

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().

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
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

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

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

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

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

336        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
337          <fx_send_id> <effect_chain> <chain_pos>"
338        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
339        - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",
343      * Bug fixes:
344        - Fixed crash which may occur when MIDI key + transpose is out of range
345        - minor valgrind fixes
346        - fixed crash which occurred when changing an already deployed sampler
347          channel to a different engine type
348        - fixed crash when deleting a sampler channel or changing engine
349          type while an instrument load was in progress
350        - bugfix: playing a note while changing the instrument could cause
351          a crash, or give "Handing back unknown region" error messages
352        - bugfix: calling SET VOICES (which Fantasia does on start and
353          refresh) could cause instruments to be unloaded
354        - Mac OS X: fixed name collision of enum in EffectControl and
355          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
356        - Mac OS X: fixed hanging threads
357        - Windows: disabled the previous thread fix on non-Mac systems, as
358          it caused hanging threads on Windows
359        - Fixed possible crashes due to corrupted MIDI/audio device list
360          after MIDI/audio device creation failure
361        - When creating MIDI instrument map entries with "PERSISTENT" type, the
362          instruments were uselessly precached with zero samples, however it still
363          took the full preloading time and on 1st program change the respective
364          instrument was completely reloaded again.
365        - fixed handling of rapid bank select and program change messages
366          sent to the same sampler channel (patch from the Open Octave
367          project, slightly adjusted)
368        - fixed crash when trying to create an effect instance with controls
369          which min and/or max values depend on the sample rate
370        - fixed bug #162
371        - bugfix: LADSPA_PATH was not evaluated correctly when containing
372          multiple paths (#165)
373        - thread safety fixes for the instrument loading thread
374        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
375          (#176)
376        - more thread safety fixes for the instrument loading thread
377        - sfz/sf2 engine: fixed crash when using small audio fragment size
378        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
379        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
380          introduced in previous fix)
381        - fixed crash when a channel received a program change while
382          playing a note in a key group
383        - fixed erroneous error message piping in VoiceBase.h
384          (labelled "Disk stream not available in time")
386    Version 1.0.0 (31 July 2009)
388      * packaging changes:
389        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
390          causing e.g. the libgig test to fail when
391          "./configure --disable-jack-driver" was used
392          (patch by Alexis Ballier)
393        - fixed compilation with gcc 4.3
394        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
395        - fixed configure so it detects x86_64 (#107)
396        - fixes for building with newer MinGW versions
397        - fix for building with bison 2.4 (#111)
398        - fixed building with libgig installed in a non-standard directory
399        - minor fix in configure for mmsystem.h detection on MinGW
400        - Windows: look for editor plugins and Fantasia using base
401          directory of liblinuxsampler dll (look in the same directory and one
402          directory above)
403        - configure script fix: removed unconditional use of SSE
404        - fixed building with sqlite installed in a non-standard directory
405        - when cross-compiling, don't try to create instruments.db
406        - fix for new mingw-w64 version, which has usleep
408      * general changes:
409        - bugfix: on some POSIX systems instrument editor plugins refused to
410          load as we used a non-portable Linux specific struct field
411          (fixes bug #70, patch by Ronald Baljeu)
412        - fixed endless loop which occured when loading an instrument editor
413          plugin DLL on Windows systems failed
414        - fixed memory leaks that occurred when liblinuxsampler was unloaded
415        - optimized the SynchronizedConfig class so it doesn't wait
416          unnecessarily long after an update
417        - added support for notifying instrument editors on note-on / note-off
418          events (e.g. to highlight the pressed keys on the virtual keyboard
419          of gigedit)
420        - added support for triggering notes by instrument editors (see above)
421        - be verbose on DLL load errors (on Linux)
422        - fixed di-harmonic triangle LFO implementation (this LFO implementation
423          is only used by very few systems, most pick the int math
424          implementation, which is usually faster)
425        - fixes for audio drivers with varying buffer sizes
426        - experimental support for running LinuxSampler as a DSSI, LV2 and
427          VST plugin
428        - notification events for stream/voice count statistics are now sent
429          only when there are actual changes
430        - added memory ordering constraints to improve stability on
431          multi-core and multi-cpu systems
432        - maximum voices and disk streams can now be altered at runtime
433        - fixed CPU feature detection on x86_64 (maybe fixes #108)
434        - automatic stacktrace mechanism is now turned off by default and can
435          be switched on by command line option "--stacktrace" (the automatic
436          stacktrace mechanism seems to be broken on most systems at the moment)
437        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
438          a pointer to the launched InstrumentEditor object
439        - added optional 3rd party user data parameter for following
440          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
441          InstrumentEditor::Launch(),
442          InstrumentManager::LaunchInstrumentEditor()
443        - theoretical fix: made SynchronizedConfig follow C++0x memory
444          model more strictly
445        - fixes for using large audio device buffers
446        - Windows: add the installation directory to the DLL search path
447          when loading an editor plugin (solves problems with VST and
448          gigedit on systems with other GTK versions installed)
450      * audio driver:
451        - removed the nonsense audio channel constraint (which was hard coded to
452          max. 100 audio channels) for most audio drivers
453        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
454          opposed to the LSCP specs
455        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
456          reflected the wrong value
457        - fixed a memory management bug in ASIO driver
458        - Makefile fix: JACK_CFLAGS wasn't used
459        - JACK: use jack_client_open instead of the deprecated
460          jack_client_new
461        - added (experimental) CoreAudio driver
462        - applied old fixes to the ASIO driver that were included in the
463          previous binary release but accidentally never committed to CVS
464          (fixes #117)
465        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
466          win64)
467        - VST: added support for sample rate and buffer size changes
468        - VST: close editor (Fantasia) when the VST is removed
469        - VST: avoid opening Fantasia more than once for each VST instance
470        - VST: export main function as "main" on Linux too (fix for
471          energyXT)
472        - VST: changed number of output channels from one stereo to 16
473          stereo
474        - added channel routing, fxsends and midi maps to the settings
475          stored in the plugin state
476        - performance optimization of AudioChannel::MixTo() and
477          AudioChannel::CopyTo() methods using GCC vector exensions
478          (if available)
479        - ASIO fixes: avoid initializing the device twice, avoid throwing
480          exception when getting parameters from a disconnected device
482      * MIDI driver:
483        - added JACK MIDI driver
484        - dispatch bank select as ordinary CC as well, the user might seriously
485          want to (mis)use it for some purpose ("fixed" in all current MIDI
486          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
487        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
488          CoreMidi or AU
489        - fixed mingw-w64 compilation error in MME driver
490        - made program change handling in MIDI thread real-time safe by
491          moving the logic to a non-RT thread
492        - fixed minor memory leak in ALSA driver
494      * instruments database:
495        - avoid time consuming samples scanning when adding instruments
496          to the instruments database
497        - added support for handling lost files in the instruments database
498        - Implemented option for adding instruments in separate directories
499          in the instruments database
500          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
501        - work-around for missing fnmatch function on Windows to make
502          instrument database compilable
503        - added instrument database support on Windows
504          works with both standalone mode and VST plugin.
505          the instruments DB file is located in
506          %USERPROFILE%\.linuxsampler\instruments.db which allows different
507          databases for each windows user
508          if no DB is present it automatically creates the .linuxsampler subdir
509          and then creates an empty DB
510        - fixed recursive import, which was broken on Windows
512      * Gigasampler format engine:
513        - fixed a memory leak that could happen when a channel was deleted
514          while notes were playing
515        - made it possible to load an instrument even if the audio thread
516          isn't running
517        - added partial support for the "Controller Triggered" MIDI rule,
518          enough for piano gigs with pedal noise samples
519        - minor fix: only mark FX sends as being modified if really the
520          respective FX send MIDI controller was used
521        - added support for GM global device volume SysEx message
522          (can be selected at compile time to either apply globally to the
523          whole sampler [default] or only to the sampler channels that are
524          connected to the respective MIDI input port the SysEx message arrived
525          on)
526        - bugfix: notes triggered at position 0 in the audio buffer were
527          sometimes wrongly killed in the same buffer, causing no sound to
528          be played
529        - added support for chromatic / drumkit mode Roland GS Sysex message
530          which is usally used to switch a part between chromatic sounds and
531          drumkit sounds (as opposed to their common default setting of MIDI
532          part 10 being a drumkit part and all other ones chromatic parts), in
533          LS however one can switch between the first 16 MIDI instrument maps
534          defined for the sampler
535        - made it possible to create multiple sample channels even if the
536          audio thread isn't running
537        - fixed crash when removing channel with active voices (#116)
538        - bugfix: on sample reference changes (instrument editor), only
539          un-cache the respective sample if it's really not used by any
540          sampler engine anymore
541        - re-cache samples in case they were changed by an instrument editor,
542          e.g. when a sample was added while playing (#82)
543        - fixed hanging notes which occured when note-off event had the exact
544          same time stamp as the voice's note-on event and occured both in the
545          same audio fragment cycle (fixes bug #112)
546        - added support for the "fine tune" and "pitch bend range"
547          instrument-level gig parameters
548        - fixed minor artifacts in pitch bend handling
549        - added support for GS Reset SysEx message
550        - allow gig files to use unlimited downward pitch shifting
551        - added a limit check for upward pitch shifting
552        - bugfix: sometimes, when playing a note twice fast, the second
553          note was silent
554        - fixed crash happening when a pitch bend event arrived at the
555          same time a new instrument was loading
557      * LSCP server:
558        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
559          react on MIDI data arriving on certain sampler channels (so far only
560          Note-On and Note-Off events are sent via this LSCP event)
561        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
562          react on MIDI data arriving on certain MIDI input devices (so far only
563          Note-On and Note-Off events are sent via this LSCP event)
564        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
566        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
567          frontends to send MIDI messages to specific sampler channel
568        - added two additional fields to GET FILE INSTRUMENT INFO command -
570        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
571          was incorrect
572        - Optimized the retrieval of the MIDI instrument mappings
573        - added new LSCP command "SET VOICES" to globally alter the maximum
574          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
575          be triggered respectively
576        - added new LSCP command "SET STREAMS" to globally alter the maximum
577          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
578          which will be triggered respectively
579        - bugfix: retry if "select" returns EINTR (this fixes a crash when
580          a gigedit file dialog is opened)
581        - close all connections when LSCPServer is deleted
582        - hard close of all sockets on exit
583        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
584          driver
586      * Bug fixes:
587        - fixed a crash which occurs when removing a sampler channel waiting
588          to start instrument loading after another channel
589        - fixed a crash which occurs when removing a sampler channel with
590          instrument loading in progress (bug #113)
591        - fixed termination caused by uncaught exception when adding MIDI
592          instrument with PERSISTENT load mode
593        - fixed possible iterator invalidations when resetting the sampler
594        - fixed memory leaks when issuing the following LSCP commands:
599        - fixed possible compilation error when sqlite is not present
600        - fixed orphaned pointers when setting maximum voices limit (bug #118)
601        - fixed crash when changing the audio output device of a sampler
602          channel with loaded instrument and start playing notes
603        - fixed endless loop in Engine::SuspendAll() (bug #120)
604        - fixed a low-level atomic load function that was broken on 64-bit
605          PowerPC, which probably could cause crashes on that platform
606        - fixed a memory management error which could cause a crash when a
607          plugin was unloaded
608        - bugfix: two private structs had the same name, which could cause
609          problems if the linker chose the wrong constructor
610        - fixed low-level ConditionServer usage bug that caused lockups on
611          Windows
614    Version 0.5.1 (6 December 2007)
616      * packaging changes:
617        - added autoconf checks for pthread library
618        - added autoconf check for pthread bug found on certain NPTL-enabled
619          glibc versions (see Gentoo bug report #194076)
620        - added autoconf checks for MS Windows
622      * general changes:
623        - bugfix: the thread used by an editor plugin didn't die when the
624          editor closed
625        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
626          out all the space. operator--() did not apply size_mask after
627          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
628          order to avoid problems with the _NonVolatileReader functions.
629        - bugfix: Stream.h: added a missing divide by BytesPerSample in
630          GetWriteSpace(). Since this function is currently only used in
631          the stream's qsort() compare function, it didn't trigger any
632          bugs.
633        - Resampler.h, Synthesizer.h: cubic interpolation now works in
634          24bit mode too. Faster method to read 24bit words on little
635          endian machines (x86): replaced 3 byte reads + shifts with a 1
636          unaligned 32bit read and shift
637        - experimental support for MS Windows (MIDI input via MME, AUDIO
638          output via ASIO)
639        - made handling of SIGINT signal (Ctrl-C) a bit more robust
640        - support for monitoring the total number of active disk streams
641          (new LSCP commands: GET TOTAL_STREAM_COUNT,
644      * AUDIO driver:
645        - added Windows ASIO low latency audio driver
647      * MIDI driver:
648        - added MME Windows MIDI driver
650      * LSCP server:
651        - added support for Windows style path / filenames, however with
652          forward slash path separators instead of backslash
653          (i.e. "C:/foo/bar.gig")
654        - allow naughty liblscp to send non-string device parameters within
655          apostrophes as well
656        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
657          "LIST FILE INSTRUMENTS <file>" and
658          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
659          about an arbitrary instrument file on the system where the sampler is
660          running on
662    Version 0.5.0 (15 October 2007)
664      * packaging changes:
665        - config.h is not going to be installed along with liblinuxsampler's
666          API header files anymore
667        - only the API relevant header (and source) files will be exported to
668          the Doxygen API documentation (explicitly listed in Doxyfile.in)
669        - added completely new XCode project files for Mac OSX which is now
670          capable to execute our autoconf environment, thus no need anymore
671          to maintain the compile time configuration file (osx/version.h) for
672          OSX manually (patch by Toshi Nagata)
673        - fixed buggy boolean --enable-foo / --disable-foo configure script
674          parameters
675        - global.h now only covers global definitions that are needed for the
676          C++ API header files, all implementation internal global definitions
677          are now in global_private.h
678        - atomic.h is not exposed to the C++ API anymore
679        - no need to include config.h anymore for using LS's API header files
680        - fixed warnings in API doc generation
682      * general changes:
683        - replaced the old, confusing MIDI program change mechanism by a
684          flexible MIDI instrument mapper which allows to map arbitrary
685          (MIDI bank, MIDI program) pairs with arbitrary
686          (engine type, instrument file, file index) triplets which will be
687          loaded on the respective channel when such MIDI program change
688          messages arrive, beside that, each entry allows to define a life-time
689          strategy for the instrument, so the user can define whether the
690          instrument should i.e. be permanently loaded (to be able to switch
691          quickly among sounds) or i.e. loaded just on demand when the
692          respective program change arrives (to safe RAM space), as well as a
693          global volume factor for each entry, so the user can adjust the volume
694          dynamic of his mapped instrument collection without having to modify
695          the instrument files, also one can manage arbitrary amount of such
696          MIDI instrument maps and assign each sampler channel individually
697          a certain map, so that i.e. separation of normal instruments and
698          drumkits is possible
699        - new notification events for tracking changes to audio/MIDI devices,
700          MIDI instrument maps, MIDI instruments, FX sends, global volume.
701        - sampler was limited to load max. 200 instruments in the background
702          due to a constant size RingBuffer FIFO which is now replaced by a
703          dynamic (unlimited) size std::list FIFO
704        - added FX sends, these allow to route audio signals to arbitrary audio
705          output channels for being processed by external effect processors
706          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
707          controllers
708        - global (sampler wide) volume can now be controlled at runtime
709        - Implemented new, improved notification system
710        - fixed compilation errors regarding OSX
711          (patch by Toshi Nagata)
712        - implemented instruments database
713        - added support for escape sequences to the instruments database
714        - added highly experimental support for on-the-fly instrument editing
715          within the sampler's process (by using instrument editor plugins),
716          you'll notice the new "Registered instrument editors:" message on
717          startup, added a new LSCP command:
718          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
719          to spawn a matching instrument editor for the instrument on the
720          given sampler channel, the plugin path can be overridden at compile
721          time with ./configure --enable-plugin-dir=/some/dir
722        - added experimental code for synchronizing instrument editors hosted
723          in the sampler's process to safely edit instruments while playing
724          without a crash (hopefully) by either suspending single regions
725          wherever possible or if unavoidable whole engine(s)
726        - fixed several issues in fundamental "Thread" class: set scheduling
727          policy and priority on thread level, set a minimum stack size for
728          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
729          threads simply inherited properties of starting thread instead of
730          setting their own policy and priority
731        - minor fix in our automatic stack trace mechanism on crashes, the
732          main process did not wait for the stack trace process to finish
733          its output
734        - fixed some minor memory leaks
735        - reenabled assembly features support, at the moment only for
736          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
737        - minor assembly fix in x86 features detection (don't use the PIC
738          register, to avoid relocations in the text segment at runtime)
739        - POSIX callback functions of Thread.h are hidden
741      * MIDI driver:
742        - dispatch bank select (MSB and LSB) messages
744      * audio driver:
745        - the ALSA audio output driver parameters now reflect the correct
746          parameter value ranges for the respective selected sound card
747          (patch by Till Wimmer, a bit fixed and extended)
749      * Gigasampler format engine:
750        - if a filter is used and EG2 finishes before EG1, let the voice
751          die when EG2 has finished (this fixes a problem with clicks and
752          voice starvation for some gigs)
753        - playback is no longer disabled during instrument loading
754        - all notes playing on a channel that changes its instrument keep
755          playing with the old instrument until they get a note off
756          command
757        - EG fix: a release value of zero could cause noises or crash
758        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
759        - EG fine tuning: when attack is zero the EG starts at a level
760          above max sustain level, which means that there is a decay phase
761          even if sustain is 100%
762        - more EG fixes: the level could sometimes go below zero and cause
763          noises or crashes
764        - minor fix of EGDecay (patch by Toshi Nagata)
765        - fixed compiler error when --enable-override-filter-type was
766          supplied to the configure script (fixes #46)
767        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
768          instead of a fix value
769        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
770          127 (solo mode) only kill voices if the respective mode really
771          changed
773      * LSCP server:
774        - fixed compile time error for old Bison versions
775          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
776        - parser now supports extended ASCII character set
777          (up to ASCII code 255, i.e. includes now umlauts and accents)
778        - filename arguments in LSCP commands now allow to use escape
779          sequences, that is directly literal as one of: \', \", \\, \n, \r,
780          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
781          code value like \xf2) (fixes bug #24)
782        - the following LSCP commands now also support escape sequences for at
783          least one of their text-based parameters (i.e. name, description):
790        - returns verbose syntax errors (line and column where syntax error
791          occured, the unexpected character and the actually expected, possible
792          character(s), the latter only if less than 5 possibilities)
793        - made sure that LSCP syntax is not affected by gigedit locale
794          settings
795        - bugfix regarding strings parameter lists: all comma separated lists
796          of strings were treated as being one string containing commas
797          (fixes #57)
799      * Bug fixes:
800        - fixed crash occurring on certain LSCP scripts (Bug 39)
801        - another thread safety fix for lscp "load engine" and "set
802          channel audio output device"
803        - fixed a crash which occurs when reassigning the same engine
804          on a sampler channel with connected MIDI device
805        - fixed a crash which occurs when changing the number of ports of a MIDI
806          device connected to a sampler channel to number less then or equal
807          to the index of the port to which the sampler channel is connected.
808        - The previous bindings were not been disconnected when altering
809          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
810          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
811        - The active stream/voice count statistic was incorrect.
812        - notification events were not been sent for some sampler
813          channel changes
814        - added default min and max values to restrict the number of allowed
815          audio output channels and MIDI input ports
816        - the connection to the PCM interface is now closed when destroying
817          an audio output device
818        - files with slash in their path or filename could not be loaded
820      * test cases:
821        - updated and fixed (haven't been touched in a while)
823    Version 0.4.0 (24 November 2006)
825      * packaging changes:
826        - changed deprecated copyright attribute to license; added ldconfig
827          to post-(un)install steps; added devel package for liblinuxsampler;
828          to linuxsampler.spec (RPM)

863        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
864          which can be overridden with --enable-global-attenuation
865        - EG fixes: made the length of "attack hold" stage more
866          accurate. Release stage can now start before attack stage
867          ends. Cancel release didn't work when sustain was zero. Attack
868          time now has a minimal value to prevent clicks.
869        - fixed pitch changes larger than one octave
870        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
871        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
872          all modes can be altered via standard GM messages, that is CC5 for
873          altering portamento time, CC65 for enabling / disabling portamento
874          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
875        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
876          parameter) and crossfade
877        - added support for the "attenuation controller threshold" gig
878          parameter
879        - added smoothing of volume changes caused by control change
880          messages
881        - sample loop parameters are now taken from the DimensionRegion
882          instead of the wave chunk
883        - fixed keyswitching for v3 gigs with a number of keyswitch splits
884          not equal to a power of two
885        - reimplementation of the filter algorithm. The new filter is more
886          accurate and supports all gig filter types, including bandreject
887          and lowpass turbo.
888        - real support for 24 bit samples - samples are not truncated to
889          16 bits anymore
890        - support for aftertouch (channel pressure, not polyphonic
891          aftertouch)
892        - LFO1 behaviour fixed (dampening from max volume instead of
893          amplifying from 0)
