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        - Aftertouch: extended API to explicitly handle channel pressure and
103          polyphonic key pressure events (so far polyphonic pressure was not
104          supported at all, and channel pressure was rerouted as CC128 but not
105          used so far).
106        - Added initial support for real-time instrument scripts. The script VM
107          code is shared by all sampler engine implemementations, however only the
108          gig file format currently provides support for storing instrument scripts
109          (as LinuxSampler extension to the original GigaStudio 4 format).
110    
111      * Gigasampler format engine:
112        - implemented the "round robin keyboard" dimension
113        - fixed round robin and random dimensions for cases when number of
114          dimension zones is not a power of two
115        - made round robin use a counter for each region instead of each
116          key
117        - bugfix: pitch LFO controller "internal+aftertouch" was broken
118        - bugfix: filter keyboard tracking was broken
119        - filter performance fix (an unnecessary copy was made of the
120          filter parameters in each sub fragment)
121        - handle special case when pan parameter in gig file has max or
122          min value
123        - Exclusive Groups: don't ever stop voices of the same note,
124          doesn't sound naturally with a drumkit
125        - fixed EG1 modulation when attack or release is zero
126        - Fixed support for 'aftertouch' attenuation controller.
127        - Fixed crash that happened with velocity split sounds under certain
128          conditions (see also previous commit on libgig).
129

133        - added a fine-tuned v1 envelope generator instead of using the
134          one from the gig engine

136        - added support for trigger=first, trigger=legato and sw_previous
137        - allow non-numerical key values ("C#4" for example)
138        - "key" opcode now sets pitch_keycenter too
139        - fixed error when unloading instrument with same sample used by
140          multiple regions

148        - fine-tuned the default velocity curve
149        - added support for transpose
150        - fixed crash when using sw_down/up
151        - improved logic for sw_lokey/hikey/up/down/last
152        - added more v1 aliases to parser
153        - reduced memory usage for sfz data
154        - RT-safeness: avoid malloc in audio thread
155        - fixed a bug that could cause voice stealing to fail
156        - optimized sample lookup

289          (modified patch which was originally posted by Sergey on LS mailing list)
290        - bugfix: generation of velocity curves etc should not be done
291          after each "#include", only after the main file is parsed
292        - bugfix: line numbers in error messages were wrong after "#include"
293    
294      * SoundFont format engine:
295        - Initial implementation (not usable yet)
296        - RT-safeness: avoid malloc in audio thread
297        - fixed a bug that could cause voice stealing to fail

300        - initial implementation of cutoff filter
301        - use linear decay and release for filter and pitch EG
302    
303      * Host plugins (VST, AU, LV2, DSSI):
304        - AU bugfix: failed to destroy its audio/MIDI devices
305        - Listen to all interfaces on Mac OS X (INADDR_ANY)
306        - VST bugfix: If the host called resume() before and after
307          changing sample rate or block size, the number of channels was
308          incorrectly set to two. This caused silence in Cubase 5.
309        - save engine type (gig, sfz or sf2) in plugin state
310        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
311          64 bit Windows
312        - AU: changed number of output channels from one stereo to 16
313          stereo
314        - VST: made it possible to build the VST plugin for Mac
315        - AU: link AU plugin dynamically if --disable-shared isn't
316          specified
317        - LV2 "state" extension support (patch by David Robillard)
318        - VST bugfix: instrument loading hang and crashed the host when
319          the plugin was loaded a second time (#174)
320        - plugin bugfix: instrument loading hang when the plugin was
321          loaded a second time (this time it's for Linux and Mac, previous
322          similar fix was for Windows)
323        - thread safety fixes for the instrument loading thread
324        - LV2: use the new lv2 package if present
325        - VST: try to open Fantasia automatically on Linux and Mac too (on
326          Linux, the Fantasia jar should be placed in <prefix>/share/java)
327        - VST: fixed crashes on Linux Ardour and EnergyXT
328        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
329          port and audio channel routing for DSSI plugins are now visible.

475        - Pass/preserve polyphonic variable data from respective "note" event
476          handler to "release" event handler.
477    
478      * Bug fixes:
479        - Fixed crash which may occur when MIDI key + transpose is out of range
480        - minor valgrind fixes
481        - fixed crash which occurred when changing an already deployed sampler
482          channel to a different engine type
483        - fixed crash when deleting a sampler channel or changing engine
484          type while an instrument load was in progress
485        - bugfix: playing a note while changing the instrument could cause
486          a crash, or give "Handing back unknown region" error messages
487        - bugfix: calling SET VOICES (which Fantasia does on start and
488          refresh) could cause instruments to be unloaded
489        - Mac OS X: fixed name collision of enum in EffectControl and
490          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
491        - Mac OS X: fixed hanging threads
492        - Windows: disabled the previous thread fix on non-Mac systems, as
493          it caused hanging threads on Windows
494        - Fixed possible crashes due to corrupted MIDI/audio device list
495          after MIDI/audio device creation failure
496        - When creating MIDI instrument map entries with "PERSISTENT" type, the
497          instruments were uselessly precached with zero samples, however it still
498          took the full preloading time and on 1st program change the respective
499          instrument was completely reloaded again.
500        - fixed handling of rapid bank select and program change messages
501          sent to the same sampler channel (patch from the Open Octave
502          project, slightly adjusted)
503        - fixed crash when trying to create an effect instance with controls
504          which min and/or max values depend on the sample rate
505        - fixed bug #162
506        - bugfix: LADSPA_PATH was not evaluated correctly when containing
507          multiple paths (#165)

513        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
514        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
515          introduced in previous fix)
516        - fixed crash when a channel received a program change while
517          playing a note in a key group
518        - fixed erroneous error message piping in VoiceBase.h
519          (labelled "Disk stream not available in time")
520        - Update effects on sample rate & period size changes (to avoid
521          crashes and noise on such transitions).
522        - ignore missing LADSPA paths without ignoring valid LADSPA paths
523          (fixes #208)
524        - Fixed bug in LSCP grammar definition which caused a statement like
525          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
526          practically irrelevant, however it caused problems with the new LSCP
527          shell's auto completion feature).
528    
529    Version 1.0.0 (31 July 2009)
530    
531      * packaging changes:
532        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
533          causing e.g. the libgig test to fail when
534          "./configure --disable-jack-driver" was used
535          (patch by Alexis Ballier)
536        - fixed compilation with gcc 4.3
537        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
538        - fixed configure so it detects x86_64 (#107)
539        - fixes for building with newer MinGW versions
540        - fix for building with bison 2.4 (#111)
541        - fixed building with libgig installed in a non-standard directory
542        - minor fix in configure for mmsystem.h detection on MinGW
543        - Windows: look for editor plugins and Fantasia using base
544          directory of liblinuxsampler dll (look in the same directory and one
545          directory above)
546        - configure script fix: removed unconditional use of SSE
547        - fixed building with sqlite installed in a non-standard directory
548        - when cross-compiling, don't try to create instruments.db
549        - fix for new mingw-w64 version, which has usleep
550    
551      * general changes:
552        - bugfix: on some POSIX systems instrument editor plugins refused to
553          load as we used a non-portable Linux specific struct field
554          (fixes bug #70, patch by Ronald Baljeu)
555        - fixed endless loop which occured when loading an instrument editor
556          plugin DLL on Windows systems failed
557        - fixed memory leaks that occurred when liblinuxsampler was unloaded
558        - optimized the SynchronizedConfig class so it doesn't wait
559          unnecessarily long after an update
560        - added support for notifying instrument editors on note-on / note-off
561          events (e.g. to highlight the pressed keys on the virtual keyboard
562          of gigedit)
563        - added support for triggering notes by instrument editors (see above)
564        - be verbose on DLL load errors (on Linux)
565        - fixed di-harmonic triangle LFO implementation (this LFO implementation
566          is only used by very few systems, most pick the int math
567          implementation, which is usually faster)
568        - fixes for audio drivers with varying buffer sizes
569        - experimental support for running LinuxSampler as a DSSI, LV2 and
570          VST plugin
571        - notification events for stream/voice count statistics are now sent
572          only when there are actual changes
573        - added memory ordering constraints to improve stability on
574          multi-core and multi-cpu systems
575        - maximum voices and disk streams can now be altered at runtime
576        - fixed CPU feature detection on x86_64 (maybe fixes #108)
577        - automatic stacktrace mechanism is now turned off by default and can
578          be switched on by command line option "--stacktrace" (the automatic
579          stacktrace mechanism seems to be broken on most systems at the moment)
580        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
581          a pointer to the launched InstrumentEditor object
582        - added optional 3rd party user data parameter for following
583          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
584          InstrumentEditor::Launch(),
585          InstrumentManager::LaunchInstrumentEditor()
586        - theoretical fix: made SynchronizedConfig follow C++0x memory
587          model more strictly
588        - fixes for using large audio device buffers
589        - Windows: add the installation directory to the DLL search path
590          when loading an editor plugin (solves problems with VST and
591          gigedit on systems with other GTK versions installed)
592        - updated linuxsampler man page
593    
594      * audio driver:
595        - removed the nonsense audio channel constraint (which was hard coded to
596          max. 100 audio channels) for most audio drivers
597        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
598          opposed to the LSCP specs
599        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
600          reflected the wrong value
601        - fixed a memory management bug in ASIO driver
602        - Makefile fix: JACK_CFLAGS wasn't used
603        - JACK: use jack_client_open instead of the deprecated
604          jack_client_new
605        - added (experimental) CoreAudio driver
606        - applied old fixes to the ASIO driver that were included in the
607          previous binary release but accidentally never committed to CVS
608          (fixes #117)
609        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
610          win64)
611        - VST: added support for sample rate and buffer size changes
612        - VST: close editor (Fantasia) when the VST is removed
613        - VST: avoid opening Fantasia more than once for each VST instance
614        - VST: export main function as "main" on Linux too (fix for
615          energyXT)
616        - VST: changed number of output channels from one stereo to 16
617          stereo
618        - added channel routing, fxsends and midi maps to the settings
619          stored in the plugin state
620        - performance optimization of AudioChannel::MixTo() and
621          AudioChannel::CopyTo() methods using GCC vector exensions
622          (if available)
623        - ASIO fixes: avoid initializing the device twice, avoid throwing
624          exception when getting parameters from a disconnected device
625    
626      * MIDI driver:
627        - added JACK MIDI driver
628        - dispatch bank select as ordinary CC as well, the user might seriously
629          want to (mis)use it for some purpose ("fixed" in all current MIDI
630          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
631        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
632          CoreMidi or AU
633        - fixed mingw-w64 compilation error in MME driver
634        - made program change handling in MIDI thread real-time safe by
635          moving the logic to a non-RT thread
636        - fixed minor memory leak in ALSA driver
637    
638      * instruments database:
639        - avoid time consuming samples scanning when adding instruments
640          to the instruments database
641        - added support for handling lost files in the instruments database
642        - Implemented option for adding instruments in separate directories
643          in the instruments database
644          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
645        - work-around for missing fnmatch function on Windows to make
646          instrument database compilable
647        - added instrument database support on Windows
648          works with both standalone mode and VST plugin.
649          the instruments DB file is located in
650          %USERPROFILE%\.linuxsampler\instruments.db which allows different
651          databases for each windows user
652          if no DB is present it automatically creates the .linuxsampler subdir
653          and then creates an empty DB
654        - fixed recursive import, which was broken on Windows
655    
656      * Gigasampler format engine:
657        - fixed a memory leak that could happen when a channel was deleted
658          while notes were playing
659        - made it possible to load an instrument even if the audio thread
660          isn't running
661        - added partial support for the "Controller Triggered" MIDI rule,
662          enough for piano gigs with pedal noise samples
663        - minor fix: only mark FX sends as being modified if really the
664          respective FX send MIDI controller was used
665        - added support for GM global device volume SysEx message
666          (can be selected at compile time to either apply globally to the
667          whole sampler [default] or only to the sampler channels that are
668          connected to the respective MIDI input port the SysEx message arrived
669          on)
670        - bugfix: notes triggered at position 0 in the audio buffer were
671          sometimes wrongly killed in the same buffer, causing no sound to
672          be played
673        - added support for chromatic / drumkit mode Roland GS Sysex message
674          which is usally used to switch a part between chromatic sounds and
675          drumkit sounds (as opposed to their common default setting of MIDI
676          part 10 being a drumkit part and all other ones chromatic parts), in
677          LS however one can switch between the first 16 MIDI instrument maps
678          defined for the sampler
679        - made it possible to create multiple sample channels even if the
680          audio thread isn't running
681        - fixed crash when removing channel with active voices (#116)
682        - bugfix: on sample reference changes (instrument editor), only
683          un-cache the respective sample if it's really not used by any
684          sampler engine anymore
685        - re-cache samples in case they were changed by an instrument editor,
686          e.g. when a sample was added while playing (#82)
687        - fixed hanging notes which occured when note-off event had the exact
688          same time stamp as the voice's note-on event and occured both in the
689          same audio fragment cycle (fixes bug #112)
690        - added support for the "fine tune" and "pitch bend range"
691          instrument-level gig parameters
692        - fixed minor artifacts in pitch bend handling
693        - added support for GS Reset SysEx message
694        - allow gig files to use unlimited downward pitch shifting
695        - added a limit check for upward pitch shifting
696        - bugfix: sometimes, when playing a note twice fast, the second
697          note was silent
698        - fixed crash happening when a pitch bend event arrived at the
699          same time a new instrument was loading
700    
701      * LSCP server:
702        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
703          react on MIDI data arriving on certain sampler channels (so far only
704          Note-On and Note-Off events are sent via this LSCP event)
705        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
706          react on MIDI data arriving on certain MIDI input devices (so far only
707          Note-On and Note-Off events are sent via this LSCP event)
708        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
709          SET DB_INSTRUMENT FILE_PATH
710        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
711          frontends to send MIDI messages to specific sampler channel
712        - added two additional fields to GET FILE INSTRUMENT INFO command -
713          KEY_BINDINGS and KEYSWITCH_BINDINGS
714        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
715          was incorrect
716        - Optimized the retrieval of the MIDI instrument mappings
717        - added new LSCP command "SET VOICES" to globally alter the maximum
718          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
719          be triggered respectively
720        - added new LSCP command "SET STREAMS" to globally alter the maximum
721          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
722          which will be triggered respectively
723        - bugfix: retry if "select" returns EINTR (this fixes a crash when
724          a gigedit file dialog is opened)
725        - close all connections when LSCPServer is deleted
726        - hard close of all sockets on exit
727        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
728          driver
729    
730      * Bug fixes:
731        - fixed a crash which occurs when removing a sampler channel waiting
732          to start instrument loading after another channel
733        - fixed a crash which occurs when removing a sampler channel with
734          instrument loading in progress (bug #113)
735        - fixed termination caused by uncaught exception when adding MIDI
736          instrument with PERSISTENT load mode
737        - fixed possible iterator invalidations when resetting the sampler
738        - fixed memory leaks when issuing the following LSCP commands:
739          GET AUDIO_OUTPUT_DRIVER INFO
740          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
741          GET MIDI_INPUT_DRIVER INFO
742          GET MIDI_INPUT_DRIVER_PARAMETER INFO
743        - fixed possible compilation error when sqlite is not present
744        - fixed orphaned pointers when setting maximum voices limit (bug #118)
745        - fixed crash when changing the audio output device of a sampler
746          channel with loaded instrument and start playing notes
747        - fixed endless loop in Engine::SuspendAll() (bug #120)
748        - fixed a low-level atomic load function that was broken on 64-bit
749          PowerPC, which probably could cause crashes on that platform
750        - fixed a memory management error which could cause a crash when a
751          plugin was unloaded
752        - bugfix: two private structs had the same name, which could cause
753          problems if the linker chose the wrong constructor
754        - fixed low-level ConditionServer usage bug that caused lockups on
755          Windows
756    
757    
758    Version 0.5.1 (6 December 2007)
759    
760      * packaging changes:
761        - added autoconf checks for pthread library
762        - added autoconf check for pthread bug found on certain NPTL-enabled
763          glibc versions (see Gentoo bug report #194076)
764        - added autoconf checks for MS Windows
765    
766      * general changes:
767        - bugfix: the thread used by an editor plugin didn't die when the
768          editor closed
769        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
770          out all the space. operator--() did not apply size_mask after
771          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
772          order to avoid problems with the _NonVolatileReader functions.
773        - bugfix: Stream.h: added a missing divide by BytesPerSample in
774          GetWriteSpace(). Since this function is currently only used in
775          the stream's qsort() compare function, it didn't trigger any
776          bugs.
777        - Resampler.h, Synthesizer.h: cubic interpolation now works in
778          24bit mode too. Faster method to read 24bit words on little
779          endian machines (x86): replaced 3 byte reads + shifts with a 1
780          unaligned 32bit read and shift
781        - experimental support for MS Windows (MIDI input via MME, AUDIO
782          output via ASIO)
783        - made handling of SIGINT signal (Ctrl-C) a bit more robust
784        - support for monitoring the total number of active disk streams
785          (new LSCP commands: GET TOTAL_STREAM_COUNT,
786          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
787    
788      * AUDIO driver:
789        - added Windows ASIO low latency audio driver
790    
791      * MIDI driver:
792        - added MME Windows MIDI driver
793    
794      * LSCP server:
795        - added support for Windows style path / filenames, however with
796          forward slash path separators instead of backslash
797          (i.e. "C:/foo/bar.gig")
798        - allow naughty liblscp to send non-string device parameters within
799          apostrophes as well
800        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
801          "LIST FILE INSTRUMENTS <file>" and
802          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
803          about an arbitrary instrument file on the system where the sampler is
804          running on
805    
806    Version 0.5.0 (15 October 2007)
807    
808      * packaging changes:
809        - config.h is not going to be installed along with liblinuxsampler's
810          API header files anymore
811        - only the API relevant header (and source) files will be exported to
812          the Doxygen API documentation (explicitly listed in Doxyfile.in)
813        - added completely new XCode project files for Mac OSX which is now
814          capable to execute our autoconf environment, thus no need anymore
815          to maintain the compile time configuration file (osx/version.h) for
816          OSX manually (patch by Toshi Nagata)
817        - fixed buggy boolean --enable-foo / --disable-foo configure script
818          parameters
819        - global.h now only covers global definitions that are needed for the
820          C++ API header files, all implementation internal global definitions
821          are now in global_private.h
822        - atomic.h is not exposed to the C++ API anymore
823        - no need to include config.h anymore for using LS's API header files
824        - fixed warnings in API doc generation
825    
826      * general changes:
827        - replaced the old, confusing MIDI program change mechanism by a
828          flexible MIDI instrument mapper which allows to map arbitrary
829          (MIDI bank, MIDI program) pairs with arbitrary
830          (engine type, instrument file, file index) triplets which will be
831          loaded on the respective channel when such MIDI program change
832          messages arrive, beside that, each entry allows to define a life-time
833          strategy for the instrument, so the user can define whether the
834          instrument should i.e. be permanently loaded (to be able to switch
835          quickly among sounds) or i.e. loaded just on demand when the
836          respective program change arrives (to safe RAM space), as well as a
837          global volume factor for each entry, so the user can adjust the volume
838          dynamic of his mapped instrument collection without having to modify
839          the instrument files, also one can manage arbitrary amount of such
840          MIDI instrument maps and assign each sampler channel individually
841          a certain map, so that i.e. separation of normal instruments and
842          drumkits is possible
843        - new notification events for tracking changes to audio/MIDI devices,
844          MIDI instrument maps, MIDI instruments, FX sends, global volume.
845        - sampler was limited to load max. 200 instruments in the background
846          due to a constant size RingBuffer FIFO which is now replaced by a
847          dynamic (unlimited) size std::list FIFO
848        - added FX sends, these allow to route audio signals to arbitrary audio
849          output channels for being processed by external effect processors
850          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
851          controllers
852        - global (sampler wide) volume can now be controlled at runtime
853        - Implemented new, improved notification system
854        - fixed compilation errors regarding OSX
855          (patch by Toshi Nagata)
856        - implemented instruments database
857        - added support for escape sequences to the instruments database
858        - added highly experimental support for on-the-fly instrument editing
859          within the sampler's process (by using instrument editor plugins),
860          you'll notice the new "Registered instrument editors:" message on
861          startup, added a new LSCP command:
862          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
863          to spawn a matching instrument editor for the instrument on the
864          given sampler channel, the plugin path can be overridden at compile
865          time with ./configure --enable-plugin-dir=/some/dir
866        - added experimental code for synchronizing instrument editors hosted
867          in the sampler's process to safely edit instruments while playing
868          without a crash (hopefully) by either suspending single regions
869          wherever possible or if unavoidable whole engine(s)
870        - fixed several issues in fundamental "Thread" class: set scheduling
871          policy and priority on thread level, set a minimum stack size for
872          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
873          threads simply inherited properties of starting thread instead of
874          setting their own policy and priority
875        - minor fix in our automatic stack trace mechanism on crashes, the
876          main process did not wait for the stack trace process to finish
877          its output
878        - fixed some minor memory leaks
879        - reenabled assembly features support, at the moment only for
880          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
881        - minor assembly fix in x86 features detection (don't use the PIC
882          register, to avoid relocations in the text segment at runtime)
883        - POSIX callback functions of Thread.h are hidden
884    
885      * MIDI driver:
886        - dispatch bank select (MSB and LSB) messages
887    
888      * audio driver:
889        - the ALSA audio output driver parameters now reflect the correct
890          parameter value ranges for the respective selected sound card
891          (patch by Till Wimmer, a bit fixed and extended)
892    
893      * Gigasampler format engine:
894        - if a filter is used and EG2 finishes before EG1, let the voice
895          die when EG2 has finished (this fixes a problem with clicks and
896          voice starvation for some gigs)
897        - playback is no longer disabled during instrument loading
898        - all notes playing on a channel that changes its instrument keep
899          playing with the old instrument until they get a note off
900          command
901        - EG fix: a release value of zero could cause noises or crash
902        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
903        - EG fine tuning: when attack is zero the EG starts at a level
904          above max sustain level, which means that there is a decay phase
905          even if sustain is 100%
906        - more EG fixes: the level could sometimes go below zero and cause
907          noises or crashes
908        - minor fix of EGDecay (patch by Toshi Nagata)
909        - fixed compiler error when --enable-override-filter-type was
910          supplied to the configure script (fixes #46)
911        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
912          instead of a fix value
913        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
914          127 (solo mode) only kill voices if the respective mode really
915          changed
916    
917      * LSCP server:
918        - fixed compile time error for old Bison versions
919          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
920        - parser now supports extended ASCII character set
921          (up to ASCII code 255, i.e. includes now umlauts and accents)
922        - filename arguments in LSCP commands now allow to use escape
923          sequences, that is directly literal as one of: \', \", \\, \n, \r,
924          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
925          code value like \xf2) (fixes bug #24)
926        - the following LSCP commands now also support escape sequences for at
927          least one of their text-based parameters (i.e. name, description):
928          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
929          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
930          "SET DB_INSTRUMENT_DIRECTORY NAME",
931          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
932          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
933          "FIND DB_INSTRUMENT_DIRECTORIES"
934        - returns verbose syntax errors (line and column where syntax error
935          occured, the unexpected character and the actually expected, possible
936          character(s), the latter only if less than 5 possibilities)
937        - made sure that LSCP syntax is not affected by gigedit locale
938          settings
939        - bugfix regarding strings parameter lists: all comma separated lists
940          of strings were treated as being one string containing commas
941          (fixes #57)
942    
943      * Bug fixes:
944        - fixed crash occurring on certain LSCP scripts (Bug 39)
945        - another thread safety fix for lscp "load engine" and "set
946          channel audio output device"
947        - fixed a crash which occurs when reassigning the same engine
948          on a sampler channel with connected MIDI device
949        - fixed a crash which occurs when changing the number of ports of a MIDI
950          device connected to a sampler channel to number less then or equal
951          to the index of the port to which the sampler channel is connected.
952        - The previous bindings were not been disconnected when altering
953          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
954          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
955        - The active stream/voice count statistic was incorrect.
956        - notification events were not been sent for some sampler
957          channel changes
958        - added default min and max values to restrict the number of allowed
959          audio output channels and MIDI input ports
960        - the connection to the PCM interface is now closed when destroying
961          an audio output device
962        - files with slash in their path or filename could not be loaded
963    
964      * test cases:
965        - updated and fixed (haven't been touched in a while)
966    
967    Version 0.4.0 (24 November 2006)
968    
969      * packaging changes:
970        - changed deprecated copyright attribute to license; added ldconfig
971          to post-(un)install steps; added devel package for liblinuxsampler;
972          to linuxsampler.spec (RPM)
973      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party
974        applications to link against liblinuxsampler        applications to link against liblinuxsampler
975      - liblinuxsampler's API documentation can be generated with 'make docs'      - liblinuxsampler's API documentation can be generated with 'make docs'
976        (Doxygen required)        (Doxygen required)
977        - added benchmark to automatically detect the best triangle LFO
978          implementation (currently either an integer math solution or a
979          di-harmonic approximation), automatic detection can be overriden
980          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
981          configure script argument though (mandatory for cross-compilation)
982        - do not automatically pick optimized gcc flags if the user already
983          provided some on his own (as CXXFLAGS)
984        - added compile time option to disable processing of All-Notes-Off MIDI
985          messages
986        - added compile time options to allow disabling the various audio and
987          MIDI drivers
988        - fixed automatic GCC CPU switch detection on PPC
989          (patch by Ebrahim Mayat)
990    
991    * Gigasampler format engine:    * Gigasampler format engine:
992        - extensive synthesis optimization
993          (reimplementation of EGs and LFO(s), removed synthesis parameter
994          prerendering and the synthesis parameter matrix in general, splitting
995          each audio fragment into subfragments now where each subfragment uses
996          constant pitch and filter coefficients. The volume coefficient is
997          linearly interpolated inside a subfragment, unless
998          --disable-interpolate-volume is set.)
999      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
1000        - improved filter cutoff calculation by adding support for the
1001          following gig parameters: Cutoff freq (used when no cutoff
1002          controller is defined), Control invert, Minimum cutoff, Velocity
1003          curve and Velocity range. The keyboard tracking now scales
1004          cutoff frequency instead of resonance.
1005        - added support for gig parameter Resonance.
1006        - fixed bug in sysex handling (patch by Juan Linietsky)
1007        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1008          which can be overridden with --enable-global-attenuation
1009        - EG fixes: made the length of "attack hold" stage more
1010          accurate. Release stage can now start before attack stage
1011          ends. Cancel release didn't work when sustain was zero. Attack
1012          time now has a minimal value to prevent clicks.
1013        - fixed pitch changes larger than one octave
1014        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1015        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1016          all modes can be altered via standard GM messages, that is CC5 for
1017          altering portamento time, CC65 for enabling / disabling portamento
1018          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1019        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1020          parameter) and crossfade
1021        - added support for the "attenuation controller threshold" gig
1022          parameter
1023        - added smoothing of volume changes caused by control change
1024          messages
1025        - sample loop parameters are now taken from the DimensionRegion
1026          instead of the wave chunk
1027        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1028          not equal to a power of two
1029        - reimplementation of the filter algorithm. The new filter is more
1030          accurate and supports all gig filter types, including bandreject
1031          and lowpass turbo.
1032        - real support for 24 bit samples - samples are not truncated to
1033          16 bits anymore
1034        - support for aftertouch (channel pressure, not polyphonic
1035          aftertouch)
1036        - LFO1 behaviour fixed (dampening from max volume instead of
1037          amplifying from 0)
1038    
1039      * LSCP server:
1040        - fixed application exit on broken pipe error (fixes bug #20)
1041        - fixed the notification messages delay due to lack of
1042          network activity (fixes bug #26)
1043        - fixed parser bug which occured on space(s) within device parameters
1044          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1045    
1046      * audio driver:
1047        - added aRts audio output driver (by no means RT safe)
1048    
1049      * MIDI driver:
1050        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1051          messages several times instead of once
1052        - API extension for MIDI drivers which already supply exact time stamps
1053          for events (i.e. for offline rendering based MIDI drivers)
1054        - added checks for bad MIDI data
1055    
1056      * linuxsampler application:
1057        - show available sampler engine types on startup
1058    
1059    * general changes:    * general changes:
1060      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new
1061        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1062        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1063        introduced for this, the behavior is the same like on a mixer console        introduced for this, the behavior is the same like on a mixer console
1064        (patch by Grigor Iliev, a bit adjusted)        (patch by Grigor Iliev, a bit adjusted). Also added configure option
1065          --enable-process-muted-channels which can be used to enable the
1066          processing of muted channels.
1067        - support for sostenuto pedal
1068        - support for monitoring the total number of active voices
1069          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1070          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1071        - fixed some memory management errors
1072        - fixed some concurrency problems that could lead to crashes when
1073          LSCP commands were executed
1074        - fixed crash when instrument loading failed previously on the same
1075          sampler channel (fixes bug #36)
