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

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

22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)

28        - build fix: ChangeFlagRelaxed.h was missing in makefile
29        - build fix: libsndfile compiler flags were missing in some
30          makefiles
31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37    
38      * general changes:
39        - Refactoring: moved the independent code from
40          the Gigasampler format engine to base classes
41        - command line option '--profile' is currently disabled, since the
42          respective profiling code is currently broken
43        - Introduced support for optional environment variable
44          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45          where the sampler shall look for instrument editor plugins
46          (patch by Luis Garrido, slightly modified).
47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512
59          (as suggested by Alex Stone)
60        - implemented sine LFO, pulse LFO and saw LFO
61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86        - Added support for multiple MIDI input ports per sampler channel (and
87          added various new C++ methods for this new feature / design change, old
88          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89          as deprecated but are still there and should provide full behavior
90          backward compatibility).
91        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92          unsafe and caused compilation error with clang 2.x).
93    
94      * Gigasampler format engine:
95        - implemented the "round robin keyboard" dimension
96        - fixed round robin and random dimensions for cases when number of
97          dimension zones is not a power of two
98        - made round robin use a counter for each region instead of each
99          key
100        - bugfix: pitch LFO controller "internal+aftertouch" was broken
101        - bugfix: filter keyboard tracking was broken
102        - filter performance fix (an unnecessary copy was made of the
103          filter parameters in each sub fragment)
104        - handle special case when pan parameter in gig file has max or
105          min value
106        - Exclusive Groups: don't ever stop voices of the same note,
107          doesn't sound naturally with a drumkit
108        - fixed EG1 modulation when attack or release is zero
109    
110      * SFZ format engine:
111        - Initial implementation (not usable yet)
112        - added support for v2 multiple stage envelope generators
113        - added a fine-tuned v1 envelope generator instead of using the
114          one from the gig engine
115        - fixed memory leak and memory handling errors
116        - added support for trigger=first, trigger=legato and sw_previous
117        - allow non-numerical key values ("C#4" for example)
118        - "key" opcode now sets pitch_keycenter too
119        - fixed error when unloading instrument with same sample used by
120          multiple regions
121        - added some opcode aliases, like loopmode for loop_mode, to be
122          more compatible
123        - added support for trigger=release and rt_decay

280        - Listen to all interfaces on Mac OS X (INADDR_ANY)
281        - VST bugfix: If the host called resume() before and after
282          changing sample rate or block size, the number of channels was
283          incorrectly set to two. This caused silence in Cubase 5.
284        - save engine type (gig, sfz or sf2) in plugin state
285        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
286          64 bit Windows
287        - AU: changed number of output channels from one stereo to 16
288          stereo
289        - VST: made it possible to build the VST plugin for Mac
290        - AU: link AU plugin dynamically if --disable-shared isn't
291          specified
292        - LV2 "state" extension support (patch by David Robillard)

294          the plugin was loaded a second time (#174)
295        - plugin bugfix: instrument loading hang when the plugin was
296          loaded a second time (this time it's for Linux and Mac, previous
297          similar fix was for Windows)
298        - thread safety fixes for the instrument loading thread
299        - LV2: use the new lv2 package if present
300        - VST: try to open Fantasia automatically on Linux and Mac too (on
301          Linux, the Fantasia jar should be placed in <prefix>/share/java)
302        - VST: fixed crashes on Linux Ardour and EnergyXT
303        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
304          port and audio channel routing for DSSI plugins are now visible.
305        - LV2: use urid and atom extensions instead of deprecated uri-map
306          and event
307        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
308        - LV2: changed number of output channels to 16 stereo, just like
309          the VST and AU plugins
310        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
311        - LV2: made LV2 plugin buildable on Windows and Mac
312        - VST: implemented retrieval and switching of programs using the
313          sampler's internal MIDI instrument mapping system
314

316        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
317          the ALSA sequencer client name
318        - removed limit of maximum amount of MIDI ports per MIDI device, since
319          there is no reason for this limit
320        - MME: fixed memory handling bug found with cppcheck
321        - MME: removed compiler warning
322        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
323          which allows to retrieve the list of CoreMIDI clients / ports and to connect
324          to them a la JACK, via the usual sampler APIs
325        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
326          the driver will automatically connect to other CoreMIDI clients' ports
327          (e.g. external MIDI devices being attached to the Mac)
328        - added support for MIDI note on velocity filter
329        - CoreMIDI: fixed memory deallocation error
330        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

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

420          introduced in previous fix)
421        - fixed crash when a channel received a program change while
422          playing a note in a key group
423        - fixed erroneous error message piping in VoiceBase.h
424          (labelled "Disk stream not available in time")
425        - Update effects on sample rate & period size changes (to avoid
426          crashes and noise on such transitions).
427    
428    Version 1.0.0 (31 July 2009)
429    
430      * packaging changes:
431        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
432          causing e.g. the libgig test to fail when
433          "./configure --disable-jack-driver" was used
434          (patch by Alexis Ballier)
435        - fixed compilation with gcc 4.3
436        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
437        - fixed configure so it detects x86_64 (#107)
438        - fixes for building with newer MinGW versions
439        - fix for building with bison 2.4 (#111)
440        - fixed building with libgig installed in a non-standard directory
441        - minor fix in configure for mmsystem.h detection on MinGW
442        - Windows: look for editor plugins and Fantasia using base
443          directory of liblinuxsampler dll (look in the same directory and one
444          directory above)
445        - configure script fix: removed unconditional use of SSE
446        - fixed building with sqlite installed in a non-standard directory
447        - when cross-compiling, don't try to create instruments.db
448        - fix for new mingw-w64 version, which has usleep
449    
450      * general changes:
451        - bugfix: on some POSIX systems instrument editor plugins refused to
452          load as we used a non-portable Linux specific struct field
453          (fixes bug #70, patch by Ronald Baljeu)
454        - fixed endless loop which occured when loading an instrument editor
455          plugin DLL on Windows systems failed
456        - fixed memory leaks that occurred when liblinuxsampler was unloaded
457        - optimized the SynchronizedConfig class so it doesn't wait
458          unnecessarily long after an update
459        - added support for notifying instrument editors on note-on / note-off
460          events (e.g. to highlight the pressed keys on the virtual keyboard
461          of gigedit)
462        - added support for triggering notes by instrument editors (see above)
463        - be verbose on DLL load errors (on Linux)
464        - fixed di-harmonic triangle LFO implementation (this LFO implementation
465          is only used by very few systems, most pick the int math
466          implementation, which is usually faster)
467        - fixes for audio drivers with varying buffer sizes
468        - experimental support for running LinuxSampler as a DSSI, LV2 and
469          VST plugin
470        - notification events for stream/voice count statistics are now sent
471          only when there are actual changes
472        - added memory ordering constraints to improve stability on
473          multi-core and multi-cpu systems
474        - maximum voices and disk streams can now be altered at runtime
475        - fixed CPU feature detection on x86_64 (maybe fixes #108)
476        - automatic stacktrace mechanism is now turned off by default and can
477          be switched on by command line option "--stacktrace" (the automatic
478          stacktrace mechanism seems to be broken on most systems at the moment)
479        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
480          a pointer to the launched InstrumentEditor object
481        - added optional 3rd party user data parameter for following
482          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
483          InstrumentEditor::Launch(),
484          InstrumentManager::LaunchInstrumentEditor()
485        - theoretical fix: made SynchronizedConfig follow C++0x memory
486          model more strictly
487        - fixes for using large audio device buffers
488        - Windows: add the installation directory to the DLL search path
489          when loading an editor plugin (solves problems with VST and
490          gigedit on systems with other GTK versions installed)
491    
492      * audio driver:
493        - removed the nonsense audio channel constraint (which was hard coded to
494          max. 100 audio channels) for most audio drivers
495        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
496          opposed to the LSCP specs
497        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
498          reflected the wrong value
499        - fixed a memory management bug in ASIO driver
500        - Makefile fix: JACK_CFLAGS wasn't used
501        - JACK: use jack_client_open instead of the deprecated
502          jack_client_new
503        - added (experimental) CoreAudio driver
504        - applied old fixes to the ASIO driver that were included in the
505          previous binary release but accidentally never committed to CVS
506          (fixes #117)
507        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
508          win64)
509        - VST: added support for sample rate and buffer size changes
510        - VST: close editor (Fantasia) when the VST is removed
511        - VST: avoid opening Fantasia more than once for each VST instance
512        - VST: export main function as "main" on Linux too (fix for
513          energyXT)
514        - VST: changed number of output channels from one stereo to 16
515          stereo
516        - added channel routing, fxsends and midi maps to the settings
517          stored in the plugin state
518        - performance optimization of AudioChannel::MixTo() and
519          AudioChannel::CopyTo() methods using GCC vector exensions
520          (if available)
521        - ASIO fixes: avoid initializing the device twice, avoid throwing
522          exception when getting parameters from a disconnected device
523    
524      * MIDI driver:
525        - added JACK MIDI driver
526        - dispatch bank select as ordinary CC as well, the user might seriously
527          want to (mis)use it for some purpose ("fixed" in all current MIDI
528          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
529        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
530          CoreMidi or AU
531        - fixed mingw-w64 compilation error in MME driver
532        - made program change handling in MIDI thread real-time safe by
533          moving the logic to a non-RT thread
534        - fixed minor memory leak in ALSA driver
535    
536      * instruments database:
537        - avoid time consuming samples scanning when adding instruments
538          to the instruments database
539        - added support for handling lost files in the instruments database
540        - Implemented option for adding instruments in separate directories
541          in the instruments database
542          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
543        - work-around for missing fnmatch function on Windows to make
544          instrument database compilable
545        - added instrument database support on Windows
546          works with both standalone mode and VST plugin.
547          the instruments DB file is located in
548          %USERPROFILE%\.linuxsampler\instruments.db which allows different
549          databases for each windows user
550          if no DB is present it automatically creates the .linuxsampler subdir
551          and then creates an empty DB
552        - fixed recursive import, which was broken on Windows
553    
554      * Gigasampler format engine:
555        - fixed a memory leak that could happen when a channel was deleted
556          while notes were playing
557        - made it possible to load an instrument even if the audio thread
558          isn't running
559        - added partial support for the "Controller Triggered" MIDI rule,
560          enough for piano gigs with pedal noise samples
561        - minor fix: only mark FX sends as being modified if really the
562          respective FX send MIDI controller was used
563        - added support for GM global device volume SysEx message
564          (can be selected at compile time to either apply globally to the
565          whole sampler [default] or only to the sampler channels that are
566          connected to the respective MIDI input port the SysEx message arrived
567          on)
568        - bugfix: notes triggered at position 0 in the audio buffer were
569          sometimes wrongly killed in the same buffer, causing no sound to
570          be played
571        - added support for chromatic / drumkit mode Roland GS Sysex message
572          which is usally used to switch a part between chromatic sounds and
573          drumkit sounds (as opposed to their common default setting of MIDI
574          part 10 being a drumkit part and all other ones chromatic parts), in
575          LS however one can switch between the first 16 MIDI instrument maps
576          defined for the sampler
577        - made it possible to create multiple sample channels even if the
578          audio thread isn't running
579        - fixed crash when removing channel with active voices (#116)
580        - bugfix: on sample reference changes (instrument editor), only
581          un-cache the respective sample if it's really not used by any
582          sampler engine anymore
583        - re-cache samples in case they were changed by an instrument editor,
584          e.g. when a sample was added while playing (#82)
585        - fixed hanging notes which occured when note-off event had the exact
586          same time stamp as the voice's note-on event and occured both in the
587          same audio fragment cycle (fixes bug #112)
588        - added support for the "fine tune" and "pitch bend range"
589          instrument-level gig parameters
590        - fixed minor artifacts in pitch bend handling
591        - added support for GS Reset SysEx message
592        - allow gig files to use unlimited downward pitch shifting
593        - added a limit check for upward pitch shifting
594        - bugfix: sometimes, when playing a note twice fast, the second
595          note was silent
596        - fixed crash happening when a pitch bend event arrived at the
597          same time a new instrument was loading
598    
599      * LSCP server:
600        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
601          react on MIDI data arriving on certain sampler channels (so far only
602          Note-On and Note-Off events are sent via this LSCP event)
603        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
604          react on MIDI data arriving on certain MIDI input devices (so far only
605          Note-On and Note-Off events are sent via this LSCP event)
606        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
607          SET DB_INSTRUMENT FILE_PATH
608        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
609          frontends to send MIDI messages to specific sampler channel
610        - added two additional fields to GET FILE INSTRUMENT INFO command -
611          KEY_BINDINGS and KEYSWITCH_BINDINGS
612        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
613          was incorrect
614        - Optimized the retrieval of the MIDI instrument mappings
615        - added new LSCP command "SET VOICES" to globally alter the maximum
616          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
617          be triggered respectively
618        - added new LSCP command "SET STREAMS" to globally alter the maximum
619          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
620          which will be triggered respectively
621        - bugfix: retry if "select" returns EINTR (this fixes a crash when
622          a gigedit file dialog is opened)
623        - close all connections when LSCPServer is deleted
624        - hard close of all sockets on exit
625        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
626          driver
627    
628      * Bug fixes:
629        - fixed a crash which occurs when removing a sampler channel waiting
630          to start instrument loading after another channel
631        - fixed a crash which occurs when removing a sampler channel with
632          instrument loading in progress (bug #113)
633        - fixed termination caused by uncaught exception when adding MIDI
634          instrument with PERSISTENT load mode
635        - fixed possible iterator invalidations when resetting the sampler
636        - fixed memory leaks when issuing the following LSCP commands:
637          GET AUDIO_OUTPUT_DRIVER INFO
638          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
639          GET MIDI_INPUT_DRIVER INFO
640          GET MIDI_INPUT_DRIVER_PARAMETER INFO
641        - fixed possible compilation error when sqlite is not present
642        - fixed orphaned pointers when setting maximum voices limit (bug #118)
643        - fixed crash when changing the audio output device of a sampler
644          channel with loaded instrument and start playing notes
645        - fixed endless loop in Engine::SuspendAll() (bug #120)
646        - fixed a low-level atomic load function that was broken on 64-bit
647          PowerPC, which probably could cause crashes on that platform
648        - fixed a memory management error which could cause a crash when a
649          plugin was unloaded
650        - bugfix: two private structs had the same name, which could cause
651          problems if the linker chose the wrong constructor
652        - fixed low-level ConditionServer usage bug that caused lockups on
653          Windows
654    
655    
656    Version 0.5.1 (6 December 2007)
657    
658      * packaging changes:
659        - added autoconf checks for pthread library
660        - added autoconf check for pthread bug found on certain NPTL-enabled
661          glibc versions (see Gentoo bug report #194076)
662        - added autoconf checks for MS Windows
663    
664      * general changes:
665        - bugfix: the thread used by an editor plugin didn't die when the
666          editor closed
667        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
668          out all the space. operator--() did not apply size_mask after
669          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
670          order to avoid problems with the _NonVolatileReader functions.
671        - bugfix: Stream.h: added a missing divide by BytesPerSample in
672          GetWriteSpace(). Since this function is currently only used in
673          the stream's qsort() compare function, it didn't trigger any
674          bugs.
675        - Resampler.h, Synthesizer.h: cubic interpolation now works in
676          24bit mode too. Faster method to read 24bit words on little
677          endian machines (x86): replaced 3 byte reads + shifts with a 1
678          unaligned 32bit read and shift
679        - experimental support for MS Windows (MIDI input via MME, AUDIO
680          output via ASIO)
681        - made handling of SIGINT signal (Ctrl-C) a bit more robust
682        - support for monitoring the total number of active disk streams
683          (new LSCP commands: GET TOTAL_STREAM_COUNT,
684          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
685    
686      * AUDIO driver:
687        - added Windows ASIO low latency audio driver
688    
689      * MIDI driver:
690        - added MME Windows MIDI driver
691    
692      * LSCP server:
693        - added support for Windows style path / filenames, however with
694          forward slash path separators instead of backslash
695          (i.e. "C:/foo/bar.gig")
696        - allow naughty liblscp to send non-string device parameters within
697          apostrophes as well
698        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
699          "LIST FILE INSTRUMENTS <file>" and
700          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
701          about an arbitrary instrument file on the system where the sampler is
702          running on
703    
704    Version 0.5.0 (15 October 2007)
705    
706      * packaging changes:
707        - config.h is not going to be installed along with liblinuxsampler's
708          API header files anymore
709        - only the API relevant header (and source) files will be exported to
710          the Doxygen API documentation (explicitly listed in Doxyfile.in)
711        - added completely new XCode project files for Mac OSX which is now
712          capable to execute our autoconf environment, thus no need anymore
713          to maintain the compile time configuration file (osx/version.h) for
714          OSX manually (patch by Toshi Nagata)
715        - fixed buggy boolean --enable-foo / --disable-foo configure script
716          parameters
717        - global.h now only covers global definitions that are needed for the
718          C++ API header files, all implementation internal global definitions
719          are now in global_private.h
720        - atomic.h is not exposed to the C++ API anymore
721        - no need to include config.h anymore for using LS's API header files
722        - fixed warnings in API doc generation
723    
724      * general changes:
725        - replaced the old, confusing MIDI program change mechanism by a
726          flexible MIDI instrument mapper which allows to map arbitrary
727          (MIDI bank, MIDI program) pairs with arbitrary
728          (engine type, instrument file, file index) triplets which will be
729          loaded on the respective channel when such MIDI program change
730          messages arrive, beside that, each entry allows to define a life-time
731          strategy for the instrument, so the user can define whether the
732          instrument should i.e. be permanently loaded (to be able to switch
733          quickly among sounds) or i.e. loaded just on demand when the
734          respective program change arrives (to safe RAM space), as well as a
735          global volume factor for each entry, so the user can adjust the volume
736          dynamic of his mapped instrument collection without having to modify
737          the instrument files, also one can manage arbitrary amount of such
738          MIDI instrument maps and assign each sampler channel individually
739          a certain map, so that i.e. separation of normal instruments and
740          drumkits is possible
741        - new notification events for tracking changes to audio/MIDI devices,
742          MIDI instrument maps, MIDI instruments, FX sends, global volume.
743        - sampler was limited to load max. 200 instruments in the background
744          due to a constant size RingBuffer FIFO which is now replaced by a
745          dynamic (unlimited) size std::list FIFO
746        - added FX sends, these allow to route audio signals to arbitrary audio
747          output channels for being processed by external effect processors
748          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
749          controllers
750        - global (sampler wide) volume can now be controlled at runtime
751        - Implemented new, improved notification system
752        - fixed compilation errors regarding OSX
753          (patch by Toshi Nagata)
754        - implemented instruments database
755        - added support for escape sequences to the instruments database
756        - added highly experimental support for on-the-fly instrument editing
757          within the sampler's process (by using instrument editor plugins),
758          you'll notice the new "Registered instrument editors:" message on
759          startup, added a new LSCP command:
760          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
761          to spawn a matching instrument editor for the instrument on the
762          given sampler channel, the plugin path can be overridden at compile
763          time with ./configure --enable-plugin-dir=/some/dir
764        - added experimental code for synchronizing instrument editors hosted
765          in the sampler's process to safely edit instruments while playing
766          without a crash (hopefully) by either suspending single regions
767          wherever possible or if unavoidable whole engine(s)
768        - fixed several issues in fundamental "Thread" class: set scheduling
769          policy and priority on thread level, set a minimum stack size for
770          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
771          threads simply inherited properties of starting thread instead of
772          setting their own policy and priority
773        - minor fix in our automatic stack trace mechanism on crashes, the
774          main process did not wait for the stack trace process to finish
775          its output
776        - fixed some minor memory leaks
777        - reenabled assembly features support, at the moment only for
778          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
779        - minor assembly fix in x86 features detection (don't use the PIC
780          register, to avoid relocations in the text segment at runtime)
781        - POSIX callback functions of Thread.h are hidden
782    
783      * MIDI driver:
784        - dispatch bank select (MSB and LSB) messages
785    
786      * audio driver:
787        - the ALSA audio output driver parameters now reflect the correct
788          parameter value ranges for the respective selected sound card
789          (patch by Till Wimmer, a bit fixed and extended)
790    
791      * Gigasampler format engine:
792        - if a filter is used and EG2 finishes before EG1, let the voice
793          die when EG2 has finished (this fixes a problem with clicks and
794          voice starvation for some gigs)
795        - playback is no longer disabled during instrument loading
796        - all notes playing on a channel that changes its instrument keep
797          playing with the old instrument until they get a note off
798          command
799        - EG fix: a release value of zero could cause noises or crash
800        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
801        - EG fine tuning: when attack is zero the EG starts at a level
802          above max sustain level, which means that there is a decay phase
803          even if sustain is 100%
804        - more EG fixes: the level could sometimes go below zero and cause
805          noises or crashes
806        - minor fix of EGDecay (patch by Toshi Nagata)
807        - fixed compiler error when --enable-override-filter-type was
808          supplied to the configure script (fixes #46)
809        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
810          instead of a fix value
811        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
812          127 (solo mode) only kill voices if the respective mode really
813          changed
814    
815      * LSCP server:
816        - fixed compile time error for old Bison versions
817          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
818        - parser now supports extended ASCII character set
819          (up to ASCII code 255, i.e. includes now umlauts and accents)
820        - filename arguments in LSCP commands now allow to use escape
821          sequences, that is directly literal as one of: \', \", \\, \n, \r,
822          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
823          code value like \xf2) (fixes bug #24)
824        - the following LSCP commands now also support escape sequences for at
825          least one of their text-based parameters (i.e. name, description):
826          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
827          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
828          "SET DB_INSTRUMENT_DIRECTORY NAME",
829          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
830          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
831          "FIND DB_INSTRUMENT_DIRECTORIES"
832        - returns verbose syntax errors (line and column where syntax error
833          occured, the unexpected character and the actually expected, possible
834          character(s), the latter only if less than 5 possibilities)
835        - made sure that LSCP syntax is not affected by gigedit locale
836          settings
837        - bugfix regarding strings parameter lists: all comma separated lists
838          of strings were treated as being one string containing commas
839          (fixes #57)
840    
841      * Bug fixes:
842        - fixed crash occurring on certain LSCP scripts (Bug 39)
843        - another thread safety fix for lscp "load engine" and "set
844          channel audio output device"
845        - fixed a crash which occurs when reassigning the same engine
846          on a sampler channel with connected MIDI device
847        - fixed a crash which occurs when changing the number of ports of a MIDI
848          device connected to a sampler channel to number less then or equal
849          to the index of the port to which the sampler channel is connected.
850        - The previous bindings were not been disconnected when altering
851          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
852          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
853        - The active stream/voice count statistic was incorrect.
854        - notification events were not been sent for some sampler
855          channel changes
856        - added default min and max values to restrict the number of allowed
857          audio output channels and MIDI input ports
858        - the connection to the PCM interface is now closed when destroying
859          an audio output device
860        - files with slash in their path or filename could not be loaded
861    
862      * test cases:
863        - updated and fixed (haven't been touched in a while)
864    
865    Version 0.4.0 (24 November 2006)
866    
867      * packaging changes:
868        - changed deprecated copyright attribute to license; added ldconfig
869          to post-(un)install steps; added devel package for liblinuxsampler;
870          to linuxsampler.spec (RPM)
