1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
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    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).

32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)

50        - fixed round robin and random dimensions for cases when number of
51          dimension zones is not a power of two
52        - made round robin use a counter for each region instead of each
53          key
54    
55      * SFZ format engine:
56        - Initial implementation (not usable yet)
57        - added support for v2 multiple stage envelope generators

81        - optimized sample lookup
82        - improved support for exclusive groups (group, off_by and
83          off_mode)

287          channel to a different engine type
288        - fixed crash when deleting a sampler channel or changing engine
289          type while an instrument load was in progress
290        - bugfix: playing a note while changing the instrument could cause
291          a crash, or give "Handing back unknown region" error messages
292        - bugfix: calling SET VOICES (which Fantasia does on start and
293          refresh) could cause instruments to be unloaded

298          it caused hanging threads on Windows
299        - Fixed possible crashes due to corrupted MIDI/audio device list
300          after MIDI/audio device creation failure
301        - When creating MIDI instrument map entries with "PERSISTENT" type, the
302          instruments were uselessly precached with zero samples, however it still
303          took the full preloading time and on 1st program change the respective
304          instrument was completely reloaded again.
305        - fixed handling of rapid bank select and program change messages
306          sent to the same sampler channel (patch from the Open Octave
307          project, slightly adjusted)
308        - fixed crash when trying to create an effect instance with controls
309          which min and/or max values depend on the sample rate
310        - fixed bug #162
311        - bugfix: LADSPA_PATH was not evaluated correctly when containing
312          multiple paths (#165)

314    Version 1.0.0 (31 July 2009)
315    
316      * packaging changes:
317        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
318          causing e.g. the libgig test to fail when
319          "./configure --disable-jack-driver" was used
320          (patch by Alexis Ballier)
321        - fixed compilation with gcc 4.3

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

732          on a sampler channel with connected MIDI device
733        - fixed a crash which occurs when changing the number of ports of a MIDI
734          device connected to a sampler channel to number less then or equal
735          to the index of the port to which the sampler channel is connected.
736        - The previous bindings were not been disconnected when altering
737          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
738          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
739        - The active stream/voice count statistic was incorrect.
740        - notification events were not been sent for some sampler
741          channel changes
742        - added default min and max values to restrict the number of allowed
743          audio output channels and MIDI input ports
744        - the connection to the PCM interface is now closed when destroying
745          an audio output device
746        - files with slash in their path or filename could not be loaded

789        - added support for gig parameter Resonance.
790        - fixed bug in sysex handling (patch by Juan Linietsky)
791        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
792          which can be overridden with --enable-global-attenuation
793        - EG fixes: made the length of "attack hold" stage more
794          accurate. Release stage can now start before attack stage
795          ends. Cancel release didn't work when sustain was zero. Attack
796          time now has a minimal value to prevent clicks.
797        - fixed pitch changes larger than one octave
798        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
799        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
800          all modes can be altered via standard GM messages, that is CC5 for
801          altering portamento time, CC65 for enabling / disabling portamento
802          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
803        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
804          parameter) and crossfade
805        - added support for the "attenuation controller threshold" gig
806          parameter
807        - added smoothing of volume changes caused by control change
808          messages
809        - sample loop parameters are now taken from the DimensionRegion
810          instead of the wave chunk
811        - fixed keyswitching for v3 gigs with a number of keyswitch splits
812          not equal to a power of two
813        - reimplementation of the filter algorithm. The new filter is more
814          accurate and supports all gig filter types, including bandreject
815          and lowpass turbo.
816        - real support for 24 bit samples - samples are not truncated to
817          16 bits anymore
818        - support for aftertouch (channel pressure, not polyphonic
819          aftertouch)
820        - LFO1 behaviour fixed (dampening from max volume instead of
821          amplifying from 0)
822

828          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
829    
830      * audio driver:
831        - added aRts audio output driver (by no means RT safe)
832    
833      * MIDI driver:
834        - fixed legacy sysex code which caused dispatching of MIDI SysEx
835          messages several times instead of once
836        - API extension for MIDI drivers which already supply exact time stamps
837          for events (i.e. for offline rendering based MIDI drivers)
838        - added checks for bad MIDI data
839    
840      * linuxsampler application:
841        - show available sampler engine types on startup
