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

97          one from the gig engine
98        - fixed memory leak and memory handling errors
99        - added support for trigger=first, trigger=legato and sw_previous
100        - allow non-numerical key values ("C#4" for example)
101        - "key" opcode now sets pitch_keycenter too
102        - fixed error when unloading instrument with same sample used by
103          multiple regions
104        - added some opcode aliases, like loopmode for loop_mode, to be
105          more compatible
106        - added support for trigger=release and rt_decay
107        - added support for off_mode=normal

266          incorrectly set to two. This caused silence in Cubase 5.
267        - save engine type (gig, sfz or sf2) in plugin state
268        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
269          64 bit Windows
270        - AU: changed number of output channels from one stereo to 16
271          stereo

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

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

289          and event
290        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

304        - MME: removed compiler warning
305        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
306          which allows to retrieve the list of CoreMIDI clients / ports and to connect
307          to them a la JACK, via the usual sampler APIs
308        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
309          the driver will automatically connect to other CoreMIDI clients' ports
310          (e.g. external MIDI devices being attached to the Mac)
311        - added support for MIDI note on velocity filter
312        - CoreMIDI: fixed memory deallocation error

325          RT context.
326        - ASIO driver: removed compiler warnings
328      * LSCP server:
329        - added support for sending MIDI CC messages via LSCP command
330          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
331        - added LSCP command "GET AVAILABLE_EFFECTS"
332        - added LSCP command "LIST AVAILABLE_EFFECTS"

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

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

886      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
887        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
888          which can be overridden with --enable-global-attenuation
889        - EG fixes: made the length of "attack hold" stage more
890          accurate. Release stage can now start before attack stage
891          ends. Cancel release didn't work when sustain was zero. Attack
892          time now has a minimal value to prevent clicks.
893        - fixed pitch changes larger than one octave
894        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
895        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
896          all modes can be altered via standard GM messages, that is CC5 for
897          altering portamento time, CC65 for enabling / disabling portamento
898          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
899        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
900          parameter) and crossfade
901        - added support for the "attenuation controller threshold" gig
902          parameter
903        - added smoothing of volume changes caused by control change
904          messages
905        - sample loop parameters are now taken from the DimensionRegion
906          instead of the wave chunk
907        - fixed keyswitching for v3 gigs with a number of keyswitch splits
908          not equal to a power of two
909        - reimplementation of the filter algorithm. The new filter is more
910          accurate and supports all gig filter types, including bandreject
911          and lowpass turbo.
912        - real support for 24 bit samples - samples are not truncated to
913          16 bits anymore
914        - support for aftertouch (channel pressure, not polyphonic
915          aftertouch)
916        - LFO1 behaviour fixed (dampening from max volume instead of
917          amplifying from 0)
