40        - support building with older jack versions
41        - support building with spaces in vst sdk path
42        - enabled automake 'subdir-objects' option and moved external
43          source references (vst, au, asio) from makefiles to cpp files,
44          in order to get rid of warnings from automake 1.14
45    
46      * general changes:
47        - Refactoring: moved the independent code from
48          the Gigasampler format engine to base classes
49        - command line option '--profile' is currently disabled, since the
50          respective profiling code is currently broken
51        - Introduced support for optional environment variable
52          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
53          where the sampler shall look for instrument editor plugins
54          (patch by Luis Garrido, slightly modified).
55        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
56        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
57        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
58          note (in this implementation of the sampler its simply hard routed to
59          the 1st effect send of the sampler channel, no matter what the actual
60          effect type is)
61        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
62          note (in this implementation of the sampler its simply hard routed to
63          the 2nd effect send of the sampler channel, no matter what the actual
64          effect type is)
65        - implemented support for internal LADSPA effects
66        - raised limit of program change queue from 100 to 512
67          (as suggested by Alex Stone)
68        - implemented sine LFO, pulse LFO and saw LFO
69        - experimental support for per voice equalization
70        - added command line option --exec-after-init
71        - Introduced new C++ API method:
72          EngineChannel::InstrumentFileName(int index)
73          allowing to retrieve the whole list of files used for the loaded
74          instrument on an engine channel (a.k.a. part). Some GigaStudio
75          instruments for example are splitted over several files like
76          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
77        - Added new C++ API method Sampler::GetGlobalMaxVoices().
78        - Added new C++ API method Sampler::GetGlobalMaxStreams().
79        - Added new C++ API method Sampler::SetGlobalMaxVoices().
80        - Added new C++ API method Sampler::SetGlobalMaxStreams().
81        - Various "const" and "restrict" optimizations.
82        - all engines: add pan CC value to instrument pan parameter before
83          applying panning, instead of using two separate pan functions in
84          series (#182)
85        - added a lock guard class for exception safe mutex handling and
86          used it everywhere appropriate
87        - Immediately apply scale tuning changes to active voices.
88        - Exposed scale tuning to C++ API (along to the already existing standard
89          SysEx way).
90        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
91          and broken for ppc64. (Seq_cst loads and stores are actually not
92          used in LS, so the bug wasn't noticable.)
93        - lsatomic.h: added ARMv7 support
94        - Added support for multiple MIDI input ports per sampler channel (and
95          added various new C++ methods for this new feature / design change, old
96          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
97          as deprecated but are still there and should provide full behavior
98          backward compatibility).
99        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
100          unsafe and caused compilation error with clang 2.x).
101        - Bugfix: only process the latest MIDI program change event.
102        - Introducing the LSCP shell, which provides convenient control of the
103          sampler from the command line by providing LSCP aware features.
104        - VirtualMidiDevice: Added support for program change.
105        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
106        - VirtualMidiDevice: Added support for pitch bend.
107        - Aftertouch: extended API to explicitly handle channel pressure and
108          polyphonic key pressure events (so far polyphonic pressure was not
109          supported at all, and channel pressure was rerouted as CC128 but not
110          used so far).
111        - Added initial support for real-time instrument scripts. The script VM
112          code is shared by all sampler engine implemementations, however only the
113          gig file format currently provides support for storing instrument scripts
114          (as LinuxSampler extension to the original GigaStudio 4 format).
115    
116      * Gigasampler format engine:
117        - implemented the "round robin keyboard" dimension
118        - fixed round robin and random dimensions for cases when number of
119          dimension zones is not a power of two
120        - made round robin use a counter for each region instead of each
121          key
122        - bugfix: pitch LFO controller "internal+aftertouch" was broken
123        - bugfix: filter keyboard tracking was broken
124        - filter performance fix (an unnecessary copy was made of the
125          filter parameters in each sub fragment)
126        - handle special case when pan parameter in gig file has max or
127          min value
128        - Exclusive Groups: don't ever stop voices of the same note,
129          doesn't sound naturally with a drumkit
130        - fixed EG1 modulation when attack or release is zero
131        - Fixed support for 'aftertouch' attenuation controller.
132        - Fixed crash that happened with velocity split sounds under certain
133          conditions (see also previous commit on libgig).

154        - fine-tuned the default velocity curve
155        - added support for transpose
156        - fixed crash when using sw_down/up
157        - improved logic for sw_lokey/hikey/up/down/last
158        - added more v1 aliases to parser
159        - reduced memory usage for sfz data
160        - RT-safeness: avoid malloc in audio thread
161        - fixed a bug that could cause voice stealing to fail

298        - bugfix: line numbers in error messages were wrong after "#include"
299        - added support for float and 32 bit sample files
300    
301      * SoundFont format engine:

311        - AU bugfix: failed to destroy its audio/MIDI devices
312        - Listen to all interfaces on Mac OS X (INADDR_ANY)
313        - VST bugfix: If the host called resume() before and after
314          changing sample rate or block size, the number of channels was
315          incorrectly set to two. This caused silence in Cubase 5.
316        - save engine type (gig, sfz or sf2) in plugin state
317        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

323          specified
324        - LV2 "state" extension support (patch by David Robillard)
325        - VST bugfix: instrument loading hang and crashed the host when
326          the plugin was loaded a second time (#174)
327        - plugin bugfix: instrument loading hang when the plugin was
328          loaded a second time (this time it's for Linux and Mac, previous
329          similar fix was for Windows)
330        - thread safety fixes for the instrument loading thread
331        - LV2: use the new lv2 package if present
332        - VST: try to open Fantasia automatically on Linux and Mac too (on
333          Linux, the Fantasia jar should be placed in <prefix>/share/java)
334        - VST: fixed crashes on Linux Ardour and EnergyXT
335        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
336          port and audio channel routing for DSSI plugins are now visible.
337        - LV2: use urid and atom extensions instead of deprecated uri-map
338          and event
339        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
340        - LV2: changed number of output channels to 16 stereo, just like
341          the VST and AU plugins
342        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
343        - LV2: made LV2 plugin buildable on Windows and Mac

345          sampler's internal MIDI instrument mapping system
346    
347      * Instrument editor interface:
348        - Changed instrument editor plugin interface, providing additional
349          informations like the EngineChannel for which the instrument editor was
350          spawned for. This allows the instrument editors to interact more actively
351          with the sampler.
352    
353      * MIDI driver:
354        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
355          the ALSA sequencer client name

359        - MME: removed compiler warning
360        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
361          which allows to retrieve the list of CoreMIDI clients / ports and to connect
362          to them a la JACK, via the usual sampler APIs
363        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
364          the driver will automatically connect to other CoreMIDI clients' ports
365          (e.g. external MIDI devices being attached to the Mac)
366        - added support for MIDI note on velocity filter
367        - CoreMIDI: fixed memory deallocation error
368        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
369          virtual keyboards in frontends / instrument editors being stuck.
370        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
371        - Implemented missing handling of MIDI "running status".
372        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
373        - MME bugfix: driver wasn't closed properly
374        - CoreMIDI: automatically connect to all input sources by default (driver
375          parameter "AUTO_BIND").
376        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
377        - CoreMIDI: fixed minor memory leak
378    
379      * audio driver:
380        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
381        - JACK audio: react on sample rate changes.

384          RT context.
385        - ASIO driver: removed compiler warnings
386        - CoreAudio: fixed minor error handling bug
387        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
388        - JACK audio: return the JACK server's current sample rate as default value
389          for audio device parameter "SAMPLERATE" (fixes #166).
390    
391      * LSCP server:
392        - added support for sending MIDI CC messages via LSCP command
393          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

426          "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
427        - provide comprehensive error messages on LSCP syntax errors
428          (suggesting expected next non-terminal symbols)

437          be the case in other shells).
438        - Added support for moving cursor left/right with arrow keys.
439        - Added support for built-in LSCP reference documentation, which will
440          automatically show the relevant LSCP reference section on screen as soon
441          as one specific LSCP command was detected while typing on the command
442          line.
443

459        - Implemented built-in script function "ignore_controller()" (may have one
460          or no argument).
461        - Implemented built-in script function "set_controller()".
462        - Added extended script VM for the Gigasampler/GigaStudio format sampler
463          engine, which extends the general instrument script VM with Giga format
464          specific variables and functions.
465        - Giga format scripts: added built-in script int constant variables
466          $GIG_DIM_CHANNEL, $GIG_DIM_LAYER, $GIG_DIM_VELOCITY, $GIG_DIM_AFTERTOUCH,

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

524        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
525          (#176)
526        - more thread safety fixes for the instrument loading thread
527        - sfz/sf2 engine: fixed crash when using small audio fragment size
528        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
529        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
530          introduced in previous fix)
531        - fixed crash when a channel received a program change while
532          playing a note in a key group
533        - fixed erroneous error message piping in VoiceBase.h
534          (labelled "Disk stream not available in time")
535        - Update effects on sample rate & period size changes (to avoid
536          crashes and noise on such transitions).
537        - ignore missing LADSPA paths without ignoring valid LADSPA paths
538          (fixes #208)
539        - Fixed bug in LSCP grammar definition which caused a statement like
540          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
541          practically irrelevant, however it caused problems with the new LSCP
542          shell's auto completion feature).
543        - Fixed MIDI program change messages being ignored if quickly executed
544          after each other (fixes #231).
545    
546    Version 1.0.0 (31 July 2009)
547    
548      * packaging changes:
549        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
550          causing e.g. the libgig test to fail when
551          "./configure --disable-jack-driver" was used
552          (patch by Alexis Ballier)
553        - fixed compilation with gcc 4.3
554        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
555        - fixed configure so it detects x86_64 (#107)
556        - fixes for building with newer MinGW versions
557        - fix for building with bison 2.4 (#111)
558        - fixed building with libgig installed in a non-standard directory
559        - minor fix in configure for mmsystem.h detection on MinGW
560        - Windows: look for editor plugins and Fantasia using base
561          directory of liblinuxsampler dll (look in the same directory and one
562          directory above)
563        - configure script fix: removed unconditional use of SSE
564        - fixed building with sqlite installed in a non-standard directory
565        - when cross-compiling, don't try to create instruments.db
566        - fix for new mingw-w64 version, which has usleep
567    
568      * general changes:
569        - bugfix: on some POSIX systems instrument editor plugins refused to
570          load as we used a non-portable Linux specific struct field
571          (fixes bug #70, patch by Ronald Baljeu)
572        - fixed endless loop which occured when loading an instrument editor
573          plugin DLL on Windows systems failed
574        - fixed memory leaks that occurred when liblinuxsampler was unloaded
575        - optimized the SynchronizedConfig class so it doesn't wait
576          unnecessarily long after an update
577        - added support for notifying instrument editors on note-on / note-off
578          events (e.g. to highlight the pressed keys on the virtual keyboard
579          of gigedit)
580        - added support for triggering notes by instrument editors (see above)
581        - be verbose on DLL load errors (on Linux)
582        - fixed di-harmonic triangle LFO implementation (this LFO implementation
583          is only used by very few systems, most pick the int math
584          implementation, which is usually faster)
585        - fixes for audio drivers with varying buffer sizes
586        - experimental support for running LinuxSampler as a DSSI, LV2 and
587          VST plugin
588        - notification events for stream/voice count statistics are now sent
589          only when there are actual changes
590        - added memory ordering constraints to improve stability on
591          multi-core and multi-cpu systems
592        - maximum voices and disk streams can now be altered at runtime
593        - fixed CPU feature detection on x86_64 (maybe fixes #108)
594        - automatic stacktrace mechanism is now turned off by default and can
595          be switched on by command line option "--stacktrace" (the automatic
596          stacktrace mechanism seems to be broken on most systems at the moment)
597        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
598          a pointer to the launched InstrumentEditor object
599        - added optional 3rd party user data parameter for following
600          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
601          InstrumentEditor::Launch(),
602          InstrumentManager::LaunchInstrumentEditor()
603        - theoretical fix: made SynchronizedConfig follow C++0x memory
604          model more strictly
605        - fixes for using large audio device buffers
606        - Windows: add the installation directory to the DLL search path
607          when loading an editor plugin (solves problems with VST and
608          gigedit on systems with other GTK versions installed)
609        - updated linuxsampler man page
610    
611      * audio driver:
612        - removed the nonsense audio channel constraint (which was hard coded to
613          max. 100 audio channels) for most audio drivers
614        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
615          opposed to the LSCP specs
616        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
617          reflected the wrong value
618        - fixed a memory management bug in ASIO driver
619        - Makefile fix: JACK_CFLAGS wasn't used
620        - JACK: use jack_client_open instead of the deprecated
621          jack_client_new
622        - added (experimental) CoreAudio driver
623        - applied old fixes to the ASIO driver that were included in the
624          previous binary release but accidentally never committed to CVS
625          (fixes #117)
626        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
627          win64)
628        - VST: added support for sample rate and buffer size changes
629        - VST: close editor (Fantasia) when the VST is removed
630        - VST: avoid opening Fantasia more than once for each VST instance
631        - VST: export main function as "main" on Linux too (fix for
632          energyXT)
633        - VST: changed number of output channels from one stereo to 16
634          stereo
635        - added channel routing, fxsends and midi maps to the settings
636          stored in the plugin state
637        - performance optimization of AudioChannel::MixTo() and
638          AudioChannel::CopyTo() methods using GCC vector exensions
639          (if available)
640        - ASIO fixes: avoid initializing the device twice, avoid throwing
641          exception when getting parameters from a disconnected device
642    
643      * MIDI driver:
644        - added JACK MIDI driver
645        - dispatch bank select as ordinary CC as well, the user might seriously
646          want to (mis)use it for some purpose ("fixed" in all current MIDI
647          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
648        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
649          CoreMidi or AU
650        - fixed mingw-w64 compilation error in MME driver
651        - made program change handling in MIDI thread real-time safe by
652          moving the logic to a non-RT thread
653        - fixed minor memory leak in ALSA driver
654    
655      * instruments database:
656        - avoid time consuming samples scanning when adding instruments
657          to the instruments database
658        - added support for handling lost files in the instruments database
659        - Implemented option for adding instruments in separate directories
660          in the instruments database
661          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
662        - work-around for missing fnmatch function on Windows to make
663          instrument database compilable
664        - added instrument database support on Windows
665          works with both standalone mode and VST plugin.
666          the instruments DB file is located in
667          %USERPROFILE%\.linuxsampler\instruments.db which allows different
668          databases for each windows user
669          if no DB is present it automatically creates the .linuxsampler subdir
670          and then creates an empty DB
671        - fixed recursive import, which was broken on Windows
672    
673      * Gigasampler format engine:
674        - fixed a memory leak that could happen when a channel was deleted
675          while notes were playing
676        - made it possible to load an instrument even if the audio thread
677          isn't running
678        - added partial support for the "Controller Triggered" MIDI rule,
679          enough for piano gigs with pedal noise samples
680        - minor fix: only mark FX sends as being modified if really the
681          respective FX send MIDI controller was used
682        - added support for GM global device volume SysEx message
683          (can be selected at compile time to either apply globally to the
684          whole sampler [default] or only to the sampler channels that are
685          connected to the respective MIDI input port the SysEx message arrived
686          on)
687        - bugfix: notes triggered at position 0 in the audio buffer were
688          sometimes wrongly killed in the same buffer, causing no sound to
689          be played
690        - added support for chromatic / drumkit mode Roland GS Sysex message
691          which is usally used to switch a part between chromatic sounds and
692          drumkit sounds (as opposed to their common default setting of MIDI
693          part 10 being a drumkit part and all other ones chromatic parts), in
694          LS however one can switch between the first 16 MIDI instrument maps
695          defined for the sampler
696        - made it possible to create multiple sample channels even if the
697          audio thread isn't running
698        - fixed crash when removing channel with active voices (#116)
699        - bugfix: on sample reference changes (instrument editor), only
700          un-cache the respective sample if it's really not used by any
701          sampler engine anymore
702        - re-cache samples in case they were changed by an instrument editor,
703          e.g. when a sample was added while playing (#82)
704        - fixed hanging notes which occured when note-off event had the exact
705          same time stamp as the voice's note-on event and occured both in the
706          same audio fragment cycle (fixes bug #112)
707        - added support for the "fine tune" and "pitch bend range"
708          instrument-level gig parameters
709        - fixed minor artifacts in pitch bend handling
710        - added support for GS Reset SysEx message
711        - allow gig files to use unlimited downward pitch shifting
712        - added a limit check for upward pitch shifting
713        - bugfix: sometimes, when playing a note twice fast, the second
714          note was silent
715        - fixed crash happening when a pitch bend event arrived at the
716          same time a new instrument was loading
717    
718      * LSCP server:
719        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
720          react on MIDI data arriving on certain sampler channels (so far only
721          Note-On and Note-Off events are sent via this LSCP event)
722        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
723          react on MIDI data arriving on certain MIDI input devices (so far only
724          Note-On and Note-Off events are sent via this LSCP event)
725        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
726          SET DB_INSTRUMENT FILE_PATH
727        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
728          frontends to send MIDI messages to specific sampler channel
729        - added two additional fields to GET FILE INSTRUMENT INFO command -
730          KEY_BINDINGS and KEYSWITCH_BINDINGS
731        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
732          was incorrect
733        - Optimized the retrieval of the MIDI instrument mappings
734        - added new LSCP command "SET VOICES" to globally alter the maximum
735          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
736          be triggered respectively
737        - added new LSCP command "SET STREAMS" to globally alter the maximum
738          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
739          which will be triggered respectively
740        - bugfix: retry if "select" returns EINTR (this fixes a crash when
741          a gigedit file dialog is opened)
742        - close all connections when LSCPServer is deleted
743        - hard close of all sockets on exit
744        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
745          driver
746    
747      * Bug fixes:
748        - fixed a crash which occurs when removing a sampler channel waiting
749          to start instrument loading after another channel
750        - fixed a crash which occurs when removing a sampler channel with
751          instrument loading in progress (bug #113)
752        - fixed termination caused by uncaught exception when adding MIDI
753          instrument with PERSISTENT load mode
754        - fixed possible iterator invalidations when resetting the sampler
755        - fixed memory leaks when issuing the following LSCP commands:
756          GET AUDIO_OUTPUT_DRIVER INFO
757          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
758          GET MIDI_INPUT_DRIVER INFO
759          GET MIDI_INPUT_DRIVER_PARAMETER INFO
760        - fixed possible compilation error when sqlite is not present
761        - fixed orphaned pointers when setting maximum voices limit (bug #118)
762        - fixed crash when changing the audio output device of a sampler
763          channel with loaded instrument and start playing notes
764        - fixed endless loop in Engine::SuspendAll() (bug #120)
765        - fixed a low-level atomic load function that was broken on 64-bit
766          PowerPC, which probably could cause crashes on that platform
767        - fixed a memory management error which could cause a crash when a
768          plugin was unloaded
769        - bugfix: two private structs had the same name, which could cause
770          problems if the linker chose the wrong constructor
771        - fixed low-level ConditionServer usage bug that caused lockups on
772          Windows
773    
774    
775    Version 0.5.1 (6 December 2007)
776    
777      * packaging changes:
778        - added autoconf checks for pthread library
779        - added autoconf check for pthread bug found on certain NPTL-enabled
780          glibc versions (see Gentoo bug report #194076)
781        - added autoconf checks for MS Windows
782    
783      * general changes:
784        - bugfix: the thread used by an editor plugin didn't die when the
785          editor closed
786        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
787          out all the space. operator--() did not apply size_mask after
788          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
789          order to avoid problems with the _NonVolatileReader functions.
790        - bugfix: Stream.h: added a missing divide by BytesPerSample in
791          GetWriteSpace(). Since this function is currently only used in
792          the stream's qsort() compare function, it didn't trigger any
793          bugs.
794        - Resampler.h, Synthesizer.h: cubic interpolation now works in
795          24bit mode too. Faster method to read 24bit words on little
796          endian machines (x86): replaced 3 byte reads + shifts with a 1
797          unaligned 32bit read and shift
798        - experimental support for MS Windows (MIDI input via MME, AUDIO
799          output via ASIO)
800        - made handling of SIGINT signal (Ctrl-C) a bit more robust
801        - support for monitoring the total number of active disk streams
802          (new LSCP commands: GET TOTAL_STREAM_COUNT,
803          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
804    
805      * AUDIO driver:
806        - added Windows ASIO low latency audio driver
807    
808      * MIDI driver:
809        - added MME Windows MIDI driver
810    
811      * LSCP server:
812        - added support for Windows style path / filenames, however with
813          forward slash path separators instead of backslash
814          (i.e. "C:/foo/bar.gig")
815        - allow naughty liblscp to send non-string device parameters within
816          apostrophes as well
817        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
818          "LIST FILE INSTRUMENTS <file>" and
819          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
820          about an arbitrary instrument file on the system where the sampler is
821          running on
822    
823    Version 0.5.0 (15 October 2007)
824    
825      * packaging changes:
826        - config.h is not going to be installed along with liblinuxsampler's
827          API header files anymore
828        - only the API relevant header (and source) files will be exported to
829          the Doxygen API documentation (explicitly listed in Doxyfile.in)
830        - added completely new XCode project files for Mac OSX which is now
831          capable to execute our autoconf environment, thus no need anymore
832          to maintain the compile time configuration file (osx/version.h) for
833          OSX manually (patch by Toshi Nagata)
834        - fixed buggy boolean --enable-foo / --disable-foo configure script
835          parameters
836        - global.h now only covers global definitions that are needed for the
837          C++ API header files, all implementation internal global definitions
838          are now in global_private.h
839        - atomic.h is not exposed to the C++ API anymore
840        - no need to include config.h anymore for using LS's API header files
841        - fixed warnings in API doc generation
842    
843      * general changes:
844        - replaced the old, confusing MIDI program change mechanism by a
845          flexible MIDI instrument mapper which allows to map arbitrary
846          (MIDI bank, MIDI program) pairs with arbitrary
847          (engine type, instrument file, file index) triplets which will be
848          loaded on the respective channel when such MIDI program change
849          messages arrive, beside that, each entry allows to define a life-time
850          strategy for the instrument, so the user can define whether the
851          instrument should i.e. be permanently loaded (to be able to switch
852          quickly among sounds) or i.e. loaded just on demand when the
853          respective program change arrives (to safe RAM space), as well as a
854          global volume factor for each entry, so the user can adjust the volume
855          dynamic of his mapped instrument collection without having to modify
856          the instrument files, also one can manage arbitrary amount of such
857          MIDI instrument maps and assign each sampler channel individually
858          a certain map, so that i.e. separation of normal instruments and
859          drumkits is possible
860        - new notification events for tracking changes to audio/MIDI devices,
861          MIDI instrument maps, MIDI instruments, FX sends, global volume.
862        - sampler was limited to load max. 200 instruments in the background
863          due to a constant size RingBuffer FIFO which is now replaced by a
864          dynamic (unlimited) size std::list FIFO
865        - added FX sends, these allow to route audio signals to arbitrary audio
866          output channels for being processed by external effect processors
867          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
868          controllers
869        - global (sampler wide) volume can now be controlled at runtime
870        - Implemented new, improved notification system
871        - fixed compilation errors regarding OSX
872          (patch by Toshi Nagata)
873        - implemented instruments database
874        - added support for escape sequences to the instruments database
875        - added highly experimental support for on-the-fly instrument editing
876          within the sampler's process (by using instrument editor plugins),
877          you'll notice the new "Registered instrument editors:" message on
878          startup, added a new LSCP command:
879          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
880          to spawn a matching instrument editor for the instrument on the
881          given sampler channel, the plugin path can be overridden at compile
882          time with ./configure --enable-plugin-dir=/some/dir
883        - added experimental code for synchronizing instrument editors hosted
884          in the sampler's process to safely edit instruments while playing
885          without a crash (hopefully) by either suspending single regions
886          wherever possible or if unavoidable whole engine(s)
887        - fixed several issues in fundamental "Thread" class: set scheduling
888          policy and priority on thread level, set a minimum stack size for
889          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
890          threads simply inherited properties of starting thread instead of
891          setting their own policy and priority
892        - minor fix in our automatic stack trace mechanism on crashes, the
893          main process did not wait for the stack trace process to finish
894          its output
895        - fixed some minor memory leaks
896        - reenabled assembly features support, at the moment only for
897          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
898        - minor assembly fix in x86 features detection (don't use the PIC
899          register, to avoid relocations in the text segment at runtime)
900        - POSIX callback functions of Thread.h are hidden
901    
902      * MIDI driver:
903        - dispatch bank select (MSB and LSB) messages
904    
905      * audio driver:
906        - the ALSA audio output driver parameters now reflect the correct
907          parameter value ranges for the respective selected sound card
908          (patch by Till Wimmer, a bit fixed and extended)
909    
910      * Gigasampler format engine:
911        - if a filter is used and EG2 finishes before EG1, let the voice
912          die when EG2 has finished (this fixes a problem with clicks and
913          voice starvation for some gigs)
914        - playback is no longer disabled during instrument loading
915        - all notes playing on a channel that changes its instrument keep
916          playing with the old instrument until they get a note off
917          command
918        - EG fix: a release value of zero could cause noises or crash
919        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
920        - EG fine tuning: when attack is zero the EG starts at a level
921          above max sustain level, which means that there is a decay phase
922          even if sustain is 100%
923        - more EG fixes: the level could sometimes go below zero and cause
924          noises or crashes
925        - minor fix of EGDecay (patch by Toshi Nagata)
926        - fixed compiler error when --enable-override-filter-type was
927          supplied to the configure script (fixes #46)
928        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
929          instead of a fix value
930        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
931          127 (solo mode) only kill voices if the respective mode really
932          changed
933    
934      * LSCP server:
935        - fixed compile time error for old Bison versions
936          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
937        - parser now supports extended ASCII character set
938          (up to ASCII code 255, i.e. includes now umlauts and accents)
939        - filename arguments in LSCP commands now allow to use escape
940          sequences, that is directly literal as one of: \', \", \\, \n, \r,
941          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
942          code value like \xf2) (fixes bug #24)
943        - the following LSCP commands now also support escape sequences for at
944          least one of their text-based parameters (i.e. name, description):
945          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
946          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
947          "SET DB_INSTRUMENT_DIRECTORY NAME",
948          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
949          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
950          "FIND DB_INSTRUMENT_DIRECTORIES"
951        - returns verbose syntax errors (line and column where syntax error
952          occured, the unexpected character and the actually expected, possible
953          character(s), the latter only if less than 5 possibilities)
954        - made sure that LSCP syntax is not affected by gigedit locale
955          settings
956        - bugfix regarding strings parameter lists: all comma separated lists
957          of strings were treated as being one string containing commas
958          (fixes #57)
959    
960      * Bug fixes:
961        - fixed crash occurring on certain LSCP scripts (Bug 39)
962        - another thread safety fix for lscp "load engine" and "set
963          channel audio output device"
964        - fixed a crash which occurs when reassigning the same engine
965          on a sampler channel with connected MIDI device
966        - fixed a crash which occurs when changing the number of ports of a MIDI
967          device connected to a sampler channel to number less then or equal
968          to the index of the port to which the sampler channel is connected.
969        - The previous bindings were not been disconnected when altering
970          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
971          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
972        - The active stream/voice count statistic was incorrect.
973        - notification events were not been sent for some sampler
974          channel changes
975        - added default min and max values to restrict the number of allowed
976          audio output channels and MIDI input ports
977        - the connection to the PCM interface is now closed when destroying
978          an audio output device
979        - files with slash in their path or filename could not be loaded
980    
981      * test cases:
982        - updated and fixed (haven't been touched in a while)
983    
984    Version 0.4.0 (24 November 2006)
985    
986      * packaging changes:
987        - changed deprecated copyright attribute to license; added ldconfig
988          to post-(un)install steps; added devel package for liblinuxsampler;
989          to linuxsampler.spec (RPM)
990        - install necessary development header files for allowing 3rd party
991          applications to link against liblinuxsampler
992        - liblinuxsampler's API documentation can be generated with 'make docs'
993          (Doxygen required)
994        - added benchmark to automatically detect the best triangle LFO
995          implementation (currently either an integer math solution or a
996          di-harmonic approximation), automatic detection can be overriden
997          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
998          configure script argument though (mandatory for cross-compilation)
999        - do not automatically pick optimized gcc flags if the user already
1000          provided some on his own (as CXXFLAGS)
1001        - added compile time option to disable processing of All-Notes-Off MIDI
1002          messages
1003        - added compile time options to allow disabling the various audio and
1004          MIDI drivers
1005        - fixed automatic GCC CPU switch detection on PPC
1006          (patch by Ebrahim Mayat)
1007    
1008      * Gigasampler format engine:
1009        - extensive synthesis optimization
1010          (reimplementation of EGs and LFO(s), removed synthesis parameter
1011          prerendering and the synthesis parameter matrix in general, splitting
1012          each audio fragment into subfragments now where each subfragment uses
1013          constant pitch and filter coefficients. The volume coefficient is
1014          linearly interpolated inside a subfragment, unless
1015          --disable-interpolate-volume is set.)
1016        - fine tuning of the EG modulation parameters
1017        - improved filter cutoff calculation by adding support for the
1018          following gig parameters: Cutoff freq (used when no cutoff
1019          controller is defined), Control invert, Minimum cutoff, Velocity
1020          curve and Velocity range. The keyboard tracking now scales
1021          cutoff frequency instead of resonance.
1022        - added support for gig parameter Resonance.
1023        - fixed bug in sysex handling (patch by Juan Linietsky)
1024        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1025          which can be overridden with --enable-global-attenuation
1026        - EG fixes: made the length of "attack hold" stage more
1027          accurate. Release stage can now start before attack stage
1028          ends. Cancel release didn't work when sustain was zero. Attack
1029          time now has a minimal value to prevent clicks.
1030        - fixed pitch changes larger than one octave
1031        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1032        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1033          all modes can be altered via standard GM messages, that is CC5 for
1034          altering portamento time, CC65 for enabling / disabling portamento
1035          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1036        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1037          parameter) and crossfade
1038        - added support for the "attenuation controller threshold" gig
1039          parameter
1040        - added smoothing of volume changes caused by control change
1041          messages
1042        - sample loop parameters are now taken from the DimensionRegion
1043          instead of the wave chunk
1044        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1045          not equal to a power of two
1046        - reimplementation of the filter algorithm. The new filter is more
1047          accurate and supports all gig filter types, including bandreject
1048          and lowpass turbo.
1049        - real support for 24 bit samples - samples are not truncated to
1050          16 bits anymore
1051        - support for aftertouch (channel pressure, not polyphonic
1052          aftertouch)
1053        - LFO1 behaviour fixed (dampening from max volume instead of
1054          amplifying from 0)
1055    
1056      * LSCP server:
1057        - fixed application exit on broken pipe error (fixes bug #20)
1058        - fixed the notification messages delay due to lack of
1059          network activity (fixes bug #26)
1060        - fixed parser bug which occured on space(s) within device parameters
1061          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1062    
1063      * audio driver:
1064        - added aRts audio output driver (by no means RT safe)
1065    
1066      * MIDI driver:
1067        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1068          messages several times instead of once
1069        - API extension for MIDI drivers which already supply exact time stamps
1070          for events (i.e. for offline rendering based MIDI drivers)
1071        - added checks for bad MIDI data
1072    
1073      * linuxsampler application:
1074        - show available sampler engine types on startup
1075    
1076      * general changes:
1077        - support for muting sampler channels and solo mode of the same, two new
1078          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1079          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1080          introduced for this, the behavior is the same like on a mixer console
1081          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1082          --enable-process-muted-channels which can be used to enable the
1083          processing of muted channels.
1084        - support for sostenuto pedal
1085        - support for monitoring the total number of active voices
1086          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1087          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1088        - fixed some memory management errors
1089        - fixed some concurrency problems that could lead to crashes when
1090          LSCP commands were executed
1091        - fixed crash when instrument loading failed previously on the same
1092          sampler channel (fixes bug #36)
1093    
1094    Version 0.3.3 (15 July 2005)
1095    
1096      * packaging changes:
1097        - fixed compilation with gcc 4.0
1098    
1099      * Gigasampler format engine:
1100        - LFO preprocessing was performed even though the respective LFO was
1101          disabled by the instrument patch (minor efficiency fix)
1102        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1103          for volume ramp downs in the same fragment (needed for current voice
1104          stealing implementation) then simply inform the user with a warning
1105          about possible click sounds and reduce the volume ramp down
1106          appropriately instead of cancelling the audio device connection
1107    
1108    Version 0.3.2 (24 June 2005)
1109    
1110    * packaging changes:    * packaging changes:
1111      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
1112        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
1113        - hand-crafted assembly optimization code can be disabled with
1114          './configure --disable-asm' (definitely not recommended)
1115        - fixed 'make dist' rule to include all necessary files
1116        - require automake (>= 1.5) for 'make -f Makefile.cvs'
1117          (due to 'dist-bzip2' automake option)
1118    
1119      * Gigasampler format engine:
1120        - support for the gig parameters for "release velocity response" curves
1121        - fine tuning of the EGADSR envelope
1122        - volume of release triggered samples now depends on note-on velocity,
1123          note length and gig parameter "release trigger decay" instead of
1124          note-off velocity.
1125        - revised voice stealing
1126          (fixes crash and endless loop caused by voice stealing)
1127        - don't reset scale tuning on instrument or audio output device change
1128        - handle key group conflicts right at the beginning of each fragment
1129          instead of when the respective voice is actually launched
1130          (fixes undefined behavior if stolen voices belonged to a key group -
1131          this case was followed by a "killed voice survived" error message)
1132        - fixed minor issue with null/silence samples
1133          (those stole voices even though they don't need a voice at all which
1134          resulted in "voice stealing didn't work out" messages)
1135        - don't reset volume, pan, pitch and MIDI controller values on
1136          instrument or audio output device change
1137    
1138      * LSCP server:
1139        - fixed some crashes (patch by Grigor Iliev, fixes #19)
1140        - fixed LSCP event "CHANNEL_INFO" notification
1141          (e.g. did not notify on volume changes or MIDI program change events)
1142    
1143      * linuxsampler application:
1144        - added command line parameters --lscp-addr and --lscp-port to override
1145          default IP address and port of LSCP server
1146
