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        - enabled automake 'subdir-objects' option and moved external
38          source references (vst, au, asio) from makefiles to cpp files,
39          in order to get rid of warnings from automake 1.14
40    
41      * general changes:
42        - Refactoring: moved the independent code from
43          the Gigasampler format engine to base classes
44        - command line option '--profile' is currently disabled, since the
45          respective profiling code is currently broken
46        - Introduced support for optional environment variable
47          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48          where the sampler shall look for instrument editor plugins
49          (patch by Luis Garrido, slightly modified).
50        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53          note (in this implementation of the sampler its simply hard routed to
54          the 1st effect send of the sampler channel, no matter what the actual
55          effect type is)
56        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57          note (in this implementation of the sampler its simply hard routed to
58          the 2nd effect send of the sampler channel, no matter what the actual
59          effect type is)
60        - implemented support for internal LADSPA effects
61        - raised limit of program change queue from 100 to 512
62          (as suggested by Alex Stone)
63        - implemented sine LFO, pulse LFO and saw LFO
64        - experimental support for per voice equalization
65        - added command line option --exec-after-init
66        - Introduced new C++ API method:
67          EngineChannel::InstrumentFileName(int index)
68          allowing to retrieve the whole list of files used for the loaded
69          instrument on an engine channel (a.k.a. part). Some GigaStudio
70          instruments for example are splitted over several files like
71          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72        - Added new C++ API method Sampler::GetGlobalMaxVoices().
73        - Added new C++ API method Sampler::GetGlobalMaxStreams().
74        - Added new C++ API method Sampler::SetGlobalMaxVoices().
75        - Added new C++ API method Sampler::SetGlobalMaxStreams().
76        - Various "const" and "restrict" optimizations.
77        - all engines: add pan CC value to instrument pan parameter before
78          applying panning, instead of using two separate pan functions in
79          series (#182)
80        - added a lock guard class for exception safe mutex handling and
81          used it everywhere appropriate
82        - Immediately apply scale tuning changes to active voices.
83        - Exposed scale tuning to C++ API (along to the already existing standard
84          SysEx way).
85        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86          and broken for ppc64. (Seq_cst loads and stores are actually not
87          used in LS, so the bug wasn't noticable.)
88        - lsatomic.h: added ARMv7 support
89        - Added support for multiple MIDI input ports per sampler channel (and
90          added various new C++ methods for this new feature / design change, old
91          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92          as deprecated but are still there and should provide full behavior
93          backward compatibility).
94        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95          unsafe and caused compilation error with clang 2.x).
96        - Bugfix: only process the latest MIDI program change event.
97        - Introducing the LSCP shell, which provides convenient control of the
98          sampler from the command line by providing LSCP aware features.
99        - VirtualMidiDevice: Added support for program change.
100        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101        - VirtualMidiDevice: Added support for pitch bend.
102    
103      * Gigasampler format engine:
104        - implemented the "round robin keyboard" dimension
105        - fixed round robin and random dimensions for cases when number of
106          dimension zones is not a power of two
107        - made round robin use a counter for each region instead of each
108          key
109        - bugfix: pitch LFO controller "internal+aftertouch" was broken
110        - bugfix: filter keyboard tracking was broken
111        - filter performance fix (an unnecessary copy was made of the
112          filter parameters in each sub fragment)
113        - handle special case when pan parameter in gig file has max or
114          min value
115        - Exclusive Groups: don't ever stop voices of the same note,
116          doesn't sound naturally with a drumkit
117        - fixed EG1 modulation when attack or release is zero
118

279    
280      * SoundFont format engine:
281        - Initial implementation (not usable yet)
282        - RT-safeness: avoid malloc in audio thread
283        - fixed a bug that could cause voice stealing to fail

285        - initial implementation of Vibrato LFO and Modulation LFO
286        - initial implementation of cutoff filter
287        - use linear decay and release for filter and pitch EG

290        - AU bugfix: failed to destroy its audio/MIDI devices
291        - Listen to all interfaces on Mac OS X (INADDR_ANY)
292        - VST bugfix: If the host called resume() before and after
293          changing sample rate or block size, the number of channels was
294          incorrectly set to two. This caused silence in Cubase 5.
295        - save engine type (gig, sfz or sf2) in plugin state
296        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
297          64 bit Windows
298        - AU: changed number of output channels from one stereo to 16
299          stereo
300        - VST: made it possible to build the VST plugin for Mac
301        - AU: link AU plugin dynamically if --disable-shared isn't
302          specified
303        - LV2 "state" extension support (patch by David Robillard)

305          the plugin was loaded a second time (#174)
306        - plugin bugfix: instrument loading hang when the plugin was
307          loaded a second time (this time it's for Linux and Mac, previous
308          similar fix was for Windows)
309        - thread safety fixes for the instrument loading thread
310        - LV2: use the new lv2 package if present
311        - VST: try to open Fantasia automatically on Linux and Mac too (on
312          Linux, the Fantasia jar should be placed in <prefix>/share/java)
313        - VST: fixed crashes on Linux Ardour and EnergyXT
314        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
315          port and audio channel routing for DSSI plugins are now visible.
316        - LV2: use urid and atom extensions instead of deprecated uri-map
317          and event
318        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
319        - LV2: changed number of output channels to 16 stereo, just like
320          the VST and AU plugins
321        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
322        - LV2: made LV2 plugin buildable on Windows and Mac
323        - VST: implemented retrieval and switching of programs using the
324          sampler's internal MIDI instrument mapping system
325    
326      * MIDI driver:
327        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
328          the ALSA sequencer client name
329        - removed limit of maximum amount of MIDI ports per MIDI device, since
330          there is no reason for this limit
331        - MME: fixed memory handling bug found with cppcheck
332        - MME: removed compiler warning
333        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
334          which allows to retrieve the list of CoreMIDI clients / ports and to connect
335          to them a la JACK, via the usual sampler APIs
336        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
337          the driver will automatically connect to other CoreMIDI clients' ports
338          (e.g. external MIDI devices being attached to the Mac)
339        - added support for MIDI note on velocity filter
340        - CoreMIDI: fixed memory deallocation error
341        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
342          virtual keyboards in frontends / instrument editors being stuck.
343        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
344        - Implemented missing handling of MIDI "running status".
345        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.

361        - added support for sending MIDI CC messages via LSCP command
362          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

410        - fixed crash when deleting a sampler channel or changing engine
411          type while an instrument load was in progress
412        - bugfix: playing a note while changing the instrument could cause
413          a crash, or give "Handing back unknown region" error messages
414        - bugfix: calling SET VOICES (which Fantasia does on start and
415          refresh) could cause instruments to be unloaded
416        - Mac OS X: fixed name collision of enum in EffectControl and
417          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
418        - Mac OS X: fixed hanging threads
419        - Windows: disabled the previous thread fix on non-Mac systems, as
420          it caused hanging threads on Windows
421        - Fixed possible crashes due to corrupted MIDI/audio device list
422          after MIDI/audio device creation failure
423        - When creating MIDI instrument map entries with "PERSISTENT" type, the
424          instruments were uselessly precached with zero samples, however it still
425          took the full preloading time and on 1st program change the respective
426          instrument was completely reloaded again.
427        - fixed handling of rapid bank select and program change messages
428          sent to the same sampler channel (patch from the Open Octave
429          project, slightly adjusted)
430        - fixed crash when trying to create an effect instance with controls
431          which min and/or max values depend on the sample rate

442          introduced in previous fix)
443        - fixed crash when a channel received a program change while
444          playing a note in a key group
445        - fixed erroneous error message piping in VoiceBase.h
446          (labelled "Disk stream not available in time")
447        - Update effects on sample rate & period size changes (to avoid
448          crashes and noise on such transitions).
449        - ignore missing LADSPA paths without ignoring valid LADSPA paths
450          (fixes #208)
451        - Fixed bug in LSCP grammar definition which caused a statement like
452          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
453          practically irrelevant, however it caused problems with the new LSCP
454          shell's auto completion feature).
455    
456    Version 1.0.0 (31 July 2009)
457    
458      * packaging changes:
459        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
460          causing e.g. the libgig test to fail when
461          "./configure --disable-jack-driver" was used
462          (patch by Alexis Ballier)
463        - fixed compilation with gcc 4.3
464        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
465        - fixed configure so it detects x86_64 (#107)
466        - fixes for building with newer MinGW versions
467        - fix for building with bison 2.4 (#111)
468        - fixed building with libgig installed in a non-standard directory
469        - minor fix in configure for mmsystem.h detection on MinGW
470        - Windows: look for editor plugins and Fantasia using base
471          directory of liblinuxsampler dll (look in the same directory and one
472          directory above)
473        - configure script fix: removed unconditional use of SSE
474        - fixed building with sqlite installed in a non-standard directory
475        - when cross-compiling, don't try to create instruments.db
476        - fix for new mingw-w64 version, which has usleep
477    
478      * general changes:
479        - bugfix: on some POSIX systems instrument editor plugins refused to
480          load as we used a non-portable Linux specific struct field
481          (fixes bug #70, patch by Ronald Baljeu)
482        - fixed endless loop which occured when loading an instrument editor
483          plugin DLL on Windows systems failed
484        - fixed memory leaks that occurred when liblinuxsampler was unloaded
485        - optimized the SynchronizedConfig class so it doesn't wait
486          unnecessarily long after an update
487        - added support for notifying instrument editors on note-on / note-off
488          events (e.g. to highlight the pressed keys on the virtual keyboard
489          of gigedit)
490        - added support for triggering notes by instrument editors (see above)
491        - be verbose on DLL load errors (on Linux)
492        - fixed di-harmonic triangle LFO implementation (this LFO implementation
493          is only used by very few systems, most pick the int math
494          implementation, which is usually faster)
495        - fixes for audio drivers with varying buffer sizes
496        - experimental support for running LinuxSampler as a DSSI, LV2 and
497          VST plugin
498        - notification events for stream/voice count statistics are now sent
499          only when there are actual changes
500        - added memory ordering constraints to improve stability on
501          multi-core and multi-cpu systems
502        - maximum voices and disk streams can now be altered at runtime
503        - fixed CPU feature detection on x86_64 (maybe fixes #108)
504        - automatic stacktrace mechanism is now turned off by default and can
505          be switched on by command line option "--stacktrace" (the automatic
506          stacktrace mechanism seems to be broken on most systems at the moment)
507        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
508          a pointer to the launched InstrumentEditor object
509        - added optional 3rd party user data parameter for following
510          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
511          InstrumentEditor::Launch(),
512          InstrumentManager::LaunchInstrumentEditor()
513        - theoretical fix: made SynchronizedConfig follow C++0x memory
514          model more strictly
515        - fixes for using large audio device buffers
516        - Windows: add the installation directory to the DLL search path
517          when loading an editor plugin (solves problems with VST and
518          gigedit on systems with other GTK versions installed)
519        - updated linuxsampler man page
520    
521      * audio driver:
522        - removed the nonsense audio channel constraint (which was hard coded to
523          max. 100 audio channels) for most audio drivers
524        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
525          opposed to the LSCP specs
526        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
527          reflected the wrong value
528        - fixed a memory management bug in ASIO driver
529        - Makefile fix: JACK_CFLAGS wasn't used
530        - JACK: use jack_client_open instead of the deprecated
531          jack_client_new
532        - added (experimental) CoreAudio driver
533        - applied old fixes to the ASIO driver that were included in the
534          previous binary release but accidentally never committed to CVS
535          (fixes #117)
536        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
537          win64)
538        - VST: added support for sample rate and buffer size changes
539        - VST: close editor (Fantasia) when the VST is removed
540        - VST: avoid opening Fantasia more than once for each VST instance
541        - VST: export main function as "main" on Linux too (fix for
542          energyXT)
543        - VST: changed number of output channels from one stereo to 16
544          stereo
545        - added channel routing, fxsends and midi maps to the settings
546          stored in the plugin state
547        - performance optimization of AudioChannel::MixTo() and
548          AudioChannel::CopyTo() methods using GCC vector exensions
549          (if available)
550        - ASIO fixes: avoid initializing the device twice, avoid throwing
551          exception when getting parameters from a disconnected device
552    
553      * MIDI driver:
554        - added JACK MIDI driver
555        - dispatch bank select as ordinary CC as well, the user might seriously
556          want to (mis)use it for some purpose ("fixed" in all current MIDI
557          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
558        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
559          CoreMidi or AU
560        - fixed mingw-w64 compilation error in MME driver
561        - made program change handling in MIDI thread real-time safe by
562          moving the logic to a non-RT thread
563        - fixed minor memory leak in ALSA driver
564    
565      * instruments database:
566        - avoid time consuming samples scanning when adding instruments
567          to the instruments database
568        - added support for handling lost files in the instruments database
569        - Implemented option for adding instruments in separate directories
570          in the instruments database
571          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
572        - work-around for missing fnmatch function on Windows to make
573          instrument database compilable
574        - added instrument database support on Windows
575          works with both standalone mode and VST plugin.
576          the instruments DB file is located in
577          %USERPROFILE%\.linuxsampler\instruments.db which allows different
578          databases for each windows user
579          if no DB is present it automatically creates the .linuxsampler subdir
580          and then creates an empty DB
581        - fixed recursive import, which was broken on Windows
582    
583      * Gigasampler format engine:
584        - fixed a memory leak that could happen when a channel was deleted
585          while notes were playing
586        - made it possible to load an instrument even if the audio thread
587          isn't running
588        - added partial support for the "Controller Triggered" MIDI rule,
589          enough for piano gigs with pedal noise samples
590        - minor fix: only mark FX sends as being modified if really the
591          respective FX send MIDI controller was used
592        - added support for GM global device volume SysEx message
593          (can be selected at compile time to either apply globally to the
594          whole sampler [default] or only to the sampler channels that are
595          connected to the respective MIDI input port the SysEx message arrived
596          on)
597        - bugfix: notes triggered at position 0 in the audio buffer were
598          sometimes wrongly killed in the same buffer, causing no sound to
599          be played
600        - added support for chromatic / drumkit mode Roland GS Sysex message
601          which is usally used to switch a part between chromatic sounds and
602          drumkit sounds (as opposed to their common default setting of MIDI
603          part 10 being a drumkit part and all other ones chromatic parts), in
604          LS however one can switch between the first 16 MIDI instrument maps
605          defined for the sampler
606        - made it possible to create multiple sample channels even if the
607          audio thread isn't running
608        - fixed crash when removing channel with active voices (#116)
609        - bugfix: on sample reference changes (instrument editor), only
610          un-cache the respective sample if it's really not used by any
611          sampler engine anymore
612        - re-cache samples in case they were changed by an instrument editor,
613          e.g. when a sample was added while playing (#82)
614        - fixed hanging notes which occured when note-off event had the exact
615          same time stamp as the voice's note-on event and occured both in the
616          same audio fragment cycle (fixes bug #112)
617        - added support for the "fine tune" and "pitch bend range"
618          instrument-level gig parameters
619        - fixed minor artifacts in pitch bend handling
620        - added support for GS Reset SysEx message
621        - allow gig files to use unlimited downward pitch shifting
622        - added a limit check for upward pitch shifting
623        - bugfix: sometimes, when playing a note twice fast, the second
624          note was silent
625        - fixed crash happening when a pitch bend event arrived at the
626          same time a new instrument was loading
627    
628      * LSCP server:
629        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
630          react on MIDI data arriving on certain sampler channels (so far only
631          Note-On and Note-Off events are sent via this LSCP event)
632        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
633          react on MIDI data arriving on certain MIDI input devices (so far only
634          Note-On and Note-Off events are sent via this LSCP event)
635        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
636          SET DB_INSTRUMENT FILE_PATH
637        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
638          frontends to send MIDI messages to specific sampler channel
639        - added two additional fields to GET FILE INSTRUMENT INFO command -
640          KEY_BINDINGS and KEYSWITCH_BINDINGS
641        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
642          was incorrect
643        - Optimized the retrieval of the MIDI instrument mappings
644        - added new LSCP command "SET VOICES" to globally alter the maximum
645          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
646          be triggered respectively
647        - added new LSCP command "SET STREAMS" to globally alter the maximum
648          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
649          which will be triggered respectively
650        - bugfix: retry if "select" returns EINTR (this fixes a crash when
651          a gigedit file dialog is opened)
652        - close all connections when LSCPServer is deleted
653        - hard close of all sockets on exit
654        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
655          driver
656    
657      * Bug fixes:
658        - fixed a crash which occurs when removing a sampler channel waiting
659          to start instrument loading after another channel
660        - fixed a crash which occurs when removing a sampler channel with
661          instrument loading in progress (bug #113)
662        - fixed termination caused by uncaught exception when adding MIDI
663          instrument with PERSISTENT load mode
664        - fixed possible iterator invalidations when resetting the sampler
665        - fixed memory leaks when issuing the following LSCP commands:
666          GET AUDIO_OUTPUT_DRIVER INFO
667          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
668          GET MIDI_INPUT_DRIVER INFO
669          GET MIDI_INPUT_DRIVER_PARAMETER INFO
670        - fixed possible compilation error when sqlite is not present
671        - fixed orphaned pointers when setting maximum voices limit (bug #118)
672        - fixed crash when changing the audio output device of a sampler
673          channel with loaded instrument and start playing notes
674        - fixed endless loop in Engine::SuspendAll() (bug #120)
675        - fixed a low-level atomic load function that was broken on 64-bit
676          PowerPC, which probably could cause crashes on that platform
677        - fixed a memory management error which could cause a crash when a
678          plugin was unloaded
679        - bugfix: two private structs had the same name, which could cause
680          problems if the linker chose the wrong constructor
681        - fixed low-level ConditionServer usage bug that caused lockups on
682          Windows
683    
684    
685    Version 0.5.1 (6 December 2007)
686    
687      * packaging changes:
688        - added autoconf checks for pthread library
689        - added autoconf check for pthread bug found on certain NPTL-enabled
690          glibc versions (see Gentoo bug report #194076)
691        - added autoconf checks for MS Windows
692    
693      * general changes:
694        - bugfix: the thread used by an editor plugin didn't die when the
695          editor closed
696        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
697          out all the space. operator--() did not apply size_mask after
698          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
699          order to avoid problems with the _NonVolatileReader functions.
700        - bugfix: Stream.h: added a missing divide by BytesPerSample in
701          GetWriteSpace(). Since this function is currently only used in
702          the stream's qsort() compare function, it didn't trigger any
703          bugs.
704        - Resampler.h, Synthesizer.h: cubic interpolation now works in
705          24bit mode too. Faster method to read 24bit words on little
706          endian machines (x86): replaced 3 byte reads + shifts with a 1
707          unaligned 32bit read and shift
708        - experimental support for MS Windows (MIDI input via MME, AUDIO
709          output via ASIO)
710        - made handling of SIGINT signal (Ctrl-C) a bit more robust
711        - support for monitoring the total number of active disk streams
712          (new LSCP commands: GET TOTAL_STREAM_COUNT,
713          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
714    
715      * AUDIO driver:
716        - added Windows ASIO low latency audio driver
717    
718      * MIDI driver:
719        - added MME Windows MIDI driver
720    
721      * LSCP server:
722        - added support for Windows style path / filenames, however with
723          forward slash path separators instead of backslash
724          (i.e. "C:/foo/bar.gig")
725        - allow naughty liblscp to send non-string device parameters within
726          apostrophes as well
727        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
728          "LIST FILE INSTRUMENTS <file>" and
729          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
730          about an arbitrary instrument file on the system where the sampler is
731          running on
732    
733    Version 0.5.0 (15 October 2007)
734    
735      * packaging changes:
736        - config.h is not going to be installed along with liblinuxsampler's
737          API header files anymore
738        - only the API relevant header (and source) files will be exported to
739          the Doxygen API documentation (explicitly listed in Doxyfile.in)
740        - added completely new XCode project files for Mac OSX which is now
741          capable to execute our autoconf environment, thus no need anymore
742          to maintain the compile time configuration file (osx/version.h) for
743          OSX manually (patch by Toshi Nagata)
744        - fixed buggy boolean --enable-foo / --disable-foo configure script
745          parameters
746        - global.h now only covers global definitions that are needed for the
747          C++ API header files, all implementation internal global definitions
748          are now in global_private.h
749        - atomic.h is not exposed to the C++ API anymore
750        - no need to include config.h anymore for using LS's API header files
751        - fixed warnings in API doc generation
752    
753      * general changes:
754        - replaced the old, confusing MIDI program change mechanism by a
755          flexible MIDI instrument mapper which allows to map arbitrary
756          (MIDI bank, MIDI program) pairs with arbitrary
757          (engine type, instrument file, file index) triplets which will be
758          loaded on the respective channel when such MIDI program change
759          messages arrive, beside that, each entry allows to define a life-time
760          strategy for the instrument, so the user can define whether the
761          instrument should i.e. be permanently loaded (to be able to switch
762          quickly among sounds) or i.e. loaded just on demand when the
763          respective program change arrives (to safe RAM space), as well as a
764          global volume factor for each entry, so the user can adjust the volume
765          dynamic of his mapped instrument collection without having to modify
766          the instrument files, also one can manage arbitrary amount of such
767          MIDI instrument maps and assign each sampler channel individually
768          a certain map, so that i.e. separation of normal instruments and
769          drumkits is possible
770        - new notification events for tracking changes to audio/MIDI devices,
771          MIDI instrument maps, MIDI instruments, FX sends, global volume.
772        - sampler was limited to load max. 200 instruments in the background
773          due to a constant size RingBuffer FIFO which is now replaced by a
774          dynamic (unlimited) size std::list FIFO
775        - added FX sends, these allow to route audio signals to arbitrary audio
776          output channels for being processed by external effect processors
777          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
778          controllers
779        - global (sampler wide) volume can now be controlled at runtime
780        - Implemented new, improved notification system
781        - fixed compilation errors regarding OSX
782          (patch by Toshi Nagata)
783        - implemented instruments database
784        - added support for escape sequences to the instruments database
785        - added highly experimental support for on-the-fly instrument editing
786          within the sampler's process (by using instrument editor plugins),
787          you'll notice the new "Registered instrument editors:" message on
788          startup, added a new LSCP command:
789          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
790          to spawn a matching instrument editor for the instrument on the
791          given sampler channel, the plugin path can be overridden at compile
792          time with ./configure --enable-plugin-dir=/some/dir
793        - added experimental code for synchronizing instrument editors hosted
794          in the sampler's process to safely edit instruments while playing
795          without a crash (hopefully) by either suspending single regions
796          wherever possible or if unavoidable whole engine(s)
797        - fixed several issues in fundamental "Thread" class: set scheduling
798          policy and priority on thread level, set a minimum stack size for
799          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
800          threads simply inherited properties of starting thread instead of
801          setting their own policy and priority
802        - minor fix in our automatic stack trace mechanism on crashes, the
803          main process did not wait for the stack trace process to finish
804          its output
805        - fixed some minor memory leaks
806        - reenabled assembly features support, at the moment only for
807          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
808        - minor assembly fix in x86 features detection (don't use the PIC
809          register, to avoid relocations in the text segment at runtime)
810        - POSIX callback functions of Thread.h are hidden
811    
812      * MIDI driver:
813        - dispatch bank select (MSB and LSB) messages
814    
815      * audio driver:
816        - the ALSA audio output driver parameters now reflect the correct
817          parameter value ranges for the respective selected sound card
818          (patch by Till Wimmer, a bit fixed and extended)
819    
820      * Gigasampler format engine:
821        - if a filter is used and EG2 finishes before EG1, let the voice
822          die when EG2 has finished (this fixes a problem with clicks and
823          voice starvation for some gigs)
824        - playback is no longer disabled during instrument loading
825        - all notes playing on a channel that changes its instrument keep
826          playing with the old instrument until they get a note off
827          command
828        - EG fix: a release value of zero could cause noises or crash
829        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
830        - EG fine tuning: when attack is zero the EG starts at a level
831          above max sustain level, which means that there is a decay phase
832          even if sustain is 100%
833        - more EG fixes: the level could sometimes go below zero and cause
834          noises or crashes
835        - minor fix of EGDecay (patch by Toshi Nagata)
836        - fixed compiler error when --enable-override-filter-type was
837          supplied to the configure script (fixes #46)
838        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
839          instead of a fix value
840        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
841          127 (solo mode) only kill voices if the respective mode really
842          changed
843    
844      * LSCP server:
845        - fixed compile time error for old Bison versions
846          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
847        - parser now supports extended ASCII character set
848          (up to ASCII code 255, i.e. includes now umlauts and accents)
849        - filename arguments in LSCP commands now allow to use escape
850          sequences, that is directly literal as one of: \', \", \\, \n, \r,
851          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
852          code value like \xf2) (fixes bug #24)
853        - the following LSCP commands now also support escape sequences for at
854          least one of their text-based parameters (i.e. name, description):
855          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
856          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
857          "SET DB_INSTRUMENT_DIRECTORY NAME",
858          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
859          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
860          "FIND DB_INSTRUMENT_DIRECTORIES"
861        - returns verbose syntax errors (line and column where syntax error
862          occured, the unexpected character and the actually expected, possible
863          character(s), the latter only if less than 5 possibilities)
864        - made sure that LSCP syntax is not affected by gigedit locale
865          settings
866        - bugfix regarding strings parameter lists: all comma separated lists
867          of strings were treated as being one string containing commas
868          (fixes #57)
869    
870      * Bug fixes:
871        - fixed crash occurring on certain LSCP scripts (Bug 39)
872        - another thread safety fix for lscp "load engine" and "set
873          channel audio output device"
874        - fixed a crash which occurs when reassigning the same engine
875          on a sampler channel with connected MIDI device
876        - fixed a crash which occurs when changing the number of ports of a MIDI
877          device connected to a sampler channel to number less then or equal
878          to the index of the port to which the sampler channel is connected.
879        - The previous bindings were not been disconnected when altering
880          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
881          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
882        - The active stream/voice count statistic was incorrect.
883        - notification events were not been sent for some sampler
884          channel changes
885        - added default min and max values to restrict the number of allowed
886          audio output channels and MIDI input ports
887        - the connection to the PCM interface is now closed when destroying
888          an audio output device
889        - files with slash in their path or filename could not be loaded
890    
891      * test cases:
892        - updated and fixed (haven't been touched in a while)
893
