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

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

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

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

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

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

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

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

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

438          be the case in other shells).
439        - Added support for moving cursor left/right with arrow keys.
440        - Added support for built-in LSCP reference documentation, which will
441          automatically show the relevant LSCP reference section on screen as soon
442          as one specific LSCP command was detected while typing on the command
443          line.
444

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

491        - Pass/preserve polyphonic variable data from respective "note" event
492          handler to "release" event handler.
493    
494      * Bug fixes:
495        - Fixed crash which may occur when MIDI key + transpose is out of range
496        - minor valgrind fixes
497        - fixed crash which occurred when changing an already deployed sampler
498          channel to a different engine type
499        - fixed crash when deleting a sampler channel or changing engine
500          type while an instrument load was in progress
501        - bugfix: playing a note while changing the instrument could cause
502          a crash, or give "Handing back unknown region" error messages
503        - bugfix: calling SET VOICES (which Fantasia does on start and
504          refresh) could cause instruments to be unloaded
505        - Mac OS X: fixed name collision of enum in EffectControl and
506          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
507        - Mac OS X: fixed hanging threads
508        - Windows: disabled the previous thread fix on non-Mac systems, as
509          it caused hanging threads on Windows
510        - Fixed possible crashes due to corrupted MIDI/audio device list
511          after MIDI/audio device creation failure
512        - When creating MIDI instrument map entries with "PERSISTENT" type, the
513          instruments were uselessly precached with zero samples, however it still
514          took the full preloading time and on 1st program change the respective
515          instrument was completely reloaded again.
516        - fixed handling of rapid bank select and program change messages
517          sent to the same sampler channel (patch from the Open Octave
518          project, slightly adjusted)
519        - fixed crash when trying to create an effect instance with controls
520          which min and/or max values depend on the sample rate
521        - fixed bug #162

525        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
526          (#176)
527        - more thread safety fixes for the instrument loading thread
528        - sfz/sf2 engine: fixed crash when using small audio fragment size
529        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
530        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
531          introduced in previous fix)
532        - fixed crash when a channel received a program change while
533          playing a note in a key group
534        - fixed erroneous error message piping in VoiceBase.h
535          (labelled "Disk stream not available in time")
536        - Update effects on sample rate & period size changes (to avoid
537          crashes and noise on such transitions).
538        - ignore missing LADSPA paths without ignoring valid LADSPA paths
539          (fixes #208)
540        - Fixed bug in LSCP grammar definition which caused a statement like
541          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
542          practically irrelevant, however it caused problems with the new LSCP
543          shell's auto completion feature).
544        - Fixed MIDI program change messages being ignored if quickly executed
545          after each other (fixes #231).
546    
547    Version 1.0.0 (31 July 2009)
548    
549      * packaging changes:
550        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
551          causing e.g. the libgig test to fail when
552          "./configure --disable-jack-driver" was used
553          (patch by Alexis Ballier)
554        - fixed compilation with gcc 4.3
555        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
556        - fixed configure so it detects x86_64 (#107)
557        - fixes for building with newer MinGW versions
558        - fix for building with bison 2.4 (#111)
559        - fixed building with libgig installed in a non-standard directory
560        - minor fix in configure for mmsystem.h detection on MinGW
561        - Windows: look for editor plugins and Fantasia using base
562          directory of liblinuxsampler dll (look in the same directory and one
563          directory above)
564        - configure script fix: removed unconditional use of SSE
565        - fixed building with sqlite installed in a non-standard directory
566        - when cross-compiling, don't try to create instruments.db
567        - fix for new mingw-w64 version, which has usleep
568    
569      * general changes:
570        - bugfix: on some POSIX systems instrument editor plugins refused to
571          load as we used a non-portable Linux specific struct field
572          (fixes bug #70, patch by Ronald Baljeu)
573        - fixed endless loop which occured when loading an instrument editor
574          plugin DLL on Windows systems failed
575        - fixed memory leaks that occurred when liblinuxsampler was unloaded
576        - optimized the SynchronizedConfig class so it doesn't wait
577          unnecessarily long after an update
578        - added support for notifying instrument editors on note-on / note-off
579          events (e.g. to highlight the pressed keys on the virtual keyboard
580          of gigedit)
581        - added support for triggering notes by instrument editors (see above)
582        - be verbose on DLL load errors (on Linux)
583        - fixed di-harmonic triangle LFO implementation (this LFO implementation
584          is only used by very few systems, most pick the int math
585          implementation, which is usually faster)
586        - fixes for audio drivers with varying buffer sizes
587        - experimental support for running LinuxSampler as a DSSI, LV2 and
588          VST plugin
589        - notification events for stream/voice count statistics are now sent
590          only when there are actual changes
591        - added memory ordering constraints to improve stability on
592          multi-core and multi-cpu systems
593        - maximum voices and disk streams can now be altered at runtime
594        - fixed CPU feature detection on x86_64 (maybe fixes #108)
595        - automatic stacktrace mechanism is now turned off by default and can
596          be switched on by command line option "--stacktrace" (the automatic
597          stacktrace mechanism seems to be broken on most systems at the moment)
598        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
599          a pointer to the launched InstrumentEditor object
600        - added optional 3rd party user data parameter for following
601          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
602          InstrumentEditor::Launch(),
603          InstrumentManager::LaunchInstrumentEditor()
604        - theoretical fix: made SynchronizedConfig follow C++0x memory
605          model more strictly
606        - fixes for using large audio device buffers
607        - Windows: add the installation directory to the DLL search path
608          when loading an editor plugin (solves problems with VST and
609          gigedit on systems with other GTK versions installed)
610        - updated linuxsampler man page
611    
612      * audio driver:
613        - removed the nonsense audio channel constraint (which was hard coded to
614          max. 100 audio channels) for most audio drivers
615        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
616          opposed to the LSCP specs
617        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
618          reflected the wrong value
619        - fixed a memory management bug in ASIO driver
620        - Makefile fix: JACK_CFLAGS wasn't used
621        - JACK: use jack_client_open instead of the deprecated
622          jack_client_new
623        - added (experimental) CoreAudio driver
624        - applied old fixes to the ASIO driver that were included in the
625          previous binary release but accidentally never committed to CVS
626          (fixes #117)
627        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
628          win64)
629        - VST: added support for sample rate and buffer size changes
630        - VST: close editor (Fantasia) when the VST is removed
631        - VST: avoid opening Fantasia more than once for each VST instance
632        - VST: export main function as "main" on Linux too (fix for
633          energyXT)
634        - VST: changed number of output channels from one stereo to 16
635          stereo
636        - added channel routing, fxsends and midi maps to the settings
637          stored in the plugin state
638        - performance optimization of AudioChannel::MixTo() and
639          AudioChannel::CopyTo() methods using GCC vector exensions
640          (if available)
641        - ASIO fixes: avoid initializing the device twice, avoid throwing
642          exception when getting parameters from a disconnected device
643    
644      * MIDI driver:
645        - added JACK MIDI driver
646        - dispatch bank select as ordinary CC as well, the user might seriously
647          want to (mis)use it for some purpose ("fixed" in all current MIDI
648          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
649        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
650          CoreMidi or AU
651        - fixed mingw-w64 compilation error in MME driver
652        - made program change handling in MIDI thread real-time safe by
653          moving the logic to a non-RT thread
654        - fixed minor memory leak in ALSA driver
655    
656      * instruments database:
657        - avoid time consuming samples scanning when adding instruments
658          to the instruments database
659        - added support for handling lost files in the instruments database
660        - Implemented option for adding instruments in separate directories
661          in the instruments database
662          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
663        - work-around for missing fnmatch function on Windows to make
664          instrument database compilable
665        - added instrument database support on Windows
666          works with both standalone mode and VST plugin.
667          the instruments DB file is located in
668          %USERPROFILE%\.linuxsampler\instruments.db which allows different
669          databases for each windows user
670          if no DB is present it automatically creates the .linuxsampler subdir
671          and then creates an empty DB
672        - fixed recursive import, which was broken on Windows
673    
674      * Gigasampler format engine:
675        - fixed a memory leak that could happen when a channel was deleted
676          while notes were playing
677        - made it possible to load an instrument even if the audio thread
678          isn't running
679        - added partial support for the "Controller Triggered" MIDI rule,
680          enough for piano gigs with pedal noise samples
681        - minor fix: only mark FX sends as being modified if really the
682          respective FX send MIDI controller was used
683        - added support for GM global device volume SysEx message
684          (can be selected at compile time to either apply globally to the
685          whole sampler [default] or only to the sampler channels that are
686          connected to the respective MIDI input port the SysEx message arrived
687          on)
688        - bugfix: notes triggered at position 0 in the audio buffer were
689          sometimes wrongly killed in the same buffer, causing no sound to
690          be played
691        - added support for chromatic / drumkit mode Roland GS Sysex message
692          which is usally used to switch a part between chromatic sounds and
693          drumkit sounds (as opposed to their common default setting of MIDI
694          part 10 being a drumkit part and all other ones chromatic parts), in
695          LS however one can switch between the first 16 MIDI instrument maps
696          defined for the sampler
697        - made it possible to create multiple sample channels even if the
698          audio thread isn't running
699        - fixed crash when removing channel with active voices (#116)
700        - bugfix: on sample reference changes (instrument editor), only
701          un-cache the respective sample if it's really not used by any
702          sampler engine anymore
703        - re-cache samples in case they were changed by an instrument editor,
704          e.g. when a sample was added while playing (#82)
705        - fixed hanging notes which occured when note-off event had the exact
706          same time stamp as the voice's note-on event and occured both in the
707          same audio fragment cycle (fixes bug #112)
708        - added support for the "fine tune" and "pitch bend range"
709          instrument-level gig parameters
710        - fixed minor artifacts in pitch bend handling
711        - added support for GS Reset SysEx message
712        - allow gig files to use unlimited downward pitch shifting
713        - added a limit check for upward pitch shifting
714        - bugfix: sometimes, when playing a note twice fast, the second
715          note was silent
716        - fixed crash happening when a pitch bend event arrived at the
717          same time a new instrument was loading
718    
719      * LSCP server:
720        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
721          react on MIDI data arriving on certain sampler channels (so far only
722          Note-On and Note-Off events are sent via this LSCP event)
723        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
724          react on MIDI data arriving on certain MIDI input devices (so far only
725          Note-On and Note-Off events are sent via this LSCP event)
726        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
727          SET DB_INSTRUMENT FILE_PATH
728        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
729          frontends to send MIDI messages to specific sampler channel
730        - added two additional fields to GET FILE INSTRUMENT INFO command -
731          KEY_BINDINGS and KEYSWITCH_BINDINGS
732        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
733          was incorrect
734        - Optimized the retrieval of the MIDI instrument mappings
735        - added new LSCP command "SET VOICES" to globally alter the maximum
736          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
737          be triggered respectively
738        - added new LSCP command "SET STREAMS" to globally alter the maximum
739          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
740          which will be triggered respectively
741        - bugfix: retry if "select" returns EINTR (this fixes a crash when
742          a gigedit file dialog is opened)
743        - close all connections when LSCPServer is deleted
744        - hard close of all sockets on exit
745        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
746          driver
747    
748      * Bug fixes:
749        - fixed a crash which occurs when removing a sampler channel waiting
750          to start instrument loading after another channel
751        - fixed a crash which occurs when removing a sampler channel with
752          instrument loading in progress (bug #113)
753        - fixed termination caused by uncaught exception when adding MIDI
754          instrument with PERSISTENT load mode
755        - fixed possible iterator invalidations when resetting the sampler
756        - fixed memory leaks when issuing the following LSCP commands:
757          GET AUDIO_OUTPUT_DRIVER INFO
758          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
759          GET MIDI_INPUT_DRIVER INFO
760          GET MIDI_INPUT_DRIVER_PARAMETER INFO
761        - fixed possible compilation error when sqlite is not present
762        - fixed orphaned pointers when setting maximum voices limit (bug #118)
763        - fixed crash when changing the audio output device of a sampler
764          channel with loaded instrument and start playing notes
765        - fixed endless loop in Engine::SuspendAll() (bug #120)
766        - fixed a low-level atomic load function that was broken on 64-bit
767          PowerPC, which probably could cause crashes on that platform
768        - fixed a memory management error which could cause a crash when a
769          plugin was unloaded
770        - bugfix: two private structs had the same name, which could cause
771          problems if the linker chose the wrong constructor
772        - fixed low-level ConditionServer usage bug that caused lockups on
773          Windows
774    
775    
776    Version 0.5.1 (6 December 2007)
777    
778      * packaging changes:
779        - added autoconf checks for pthread library
780        - added autoconf check for pthread bug found on certain NPTL-enabled
781          glibc versions (see Gentoo bug report #194076)
782        - added autoconf checks for MS Windows
783    
784      * general changes:
785        - bugfix: the thread used by an editor plugin didn't die when the
786          editor closed
787        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
788          out all the space. operator--() did not apply size_mask after
789          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
790          order to avoid problems with the _NonVolatileReader functions.
791        - bugfix: Stream.h: added a missing divide by BytesPerSample in
792          GetWriteSpace(). Since this function is currently only used in
793          the stream's qsort() compare function, it didn't trigger any
794          bugs.
795        - Resampler.h, Synthesizer.h: cubic interpolation now works in
796          24bit mode too. Faster method to read 24bit words on little
797          endian machines (x86): replaced 3 byte reads + shifts with a 1
798          unaligned 32bit read and shift
799        - experimental support for MS Windows (MIDI input via MME, AUDIO
800          output via ASIO)
801        - made handling of SIGINT signal (Ctrl-C) a bit more robust
802        - support for monitoring the total number of active disk streams
803          (new LSCP commands: GET TOTAL_STREAM_COUNT,
804          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
805    
806      * AUDIO driver:
807        - added Windows ASIO low latency audio driver
808    
809      * MIDI driver:
810        - added MME Windows MIDI driver
811    
812      * LSCP server:
813        - added support for Windows style path / filenames, however with
814          forward slash path separators instead of backslash
815          (i.e. "C:/foo/bar.gig")
816        - allow naughty liblscp to send non-string device parameters within
817          apostrophes as well
818        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
819          "LIST FILE INSTRUMENTS <file>" and
820          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
821          about an arbitrary instrument file on the system where the sampler is
822          running on
823    
824    Version 0.5.0 (15 October 2007)
825    
826      * packaging changes:
827        - config.h is not going to be installed along with liblinuxsampler's
828          API header files anymore
829        - only the API relevant header (and source) files will be exported to
830          the Doxygen API documentation (explicitly listed in Doxyfile.in)
831        - added completely new XCode project files for Mac OSX which is now
832          capable to execute our autoconf environment, thus no need anymore
833          to maintain the compile time configuration file (osx/version.h) for
834          OSX manually (patch by Toshi Nagata)
835        - fixed buggy boolean --enable-foo / --disable-foo configure script
836          parameters
837        - global.h now only covers global definitions that are needed for the
838          C++ API header files, all implementation internal global definitions
839          are now in global_private.h
840        - atomic.h is not exposed to the C++ API anymore
841        - no need to include config.h anymore for using LS's API header files
842        - fixed warnings in API doc generation
843    
844      * general changes:
845        - replaced the old, confusing MIDI program change mechanism by a
846          flexible MIDI instrument mapper which allows to map arbitrary
847          (MIDI bank, MIDI program) pairs with arbitrary
848          (engine type, instrument file, file index) triplets which will be
849          loaded on the respective channel when such MIDI program change
850          messages arrive, beside that, each entry allows to define a life-time
851          strategy for the instrument, so the user can define whether the
852          instrument should i.e. be permanently loaded (to be able to switch
853          quickly among sounds) or i.e. loaded just on demand when the
854          respective program change arrives (to safe RAM space), as well as a
855          global volume factor for each entry, so the user can adjust the volume
856          dynamic of his mapped instrument collection without having to modify
857          the instrument files, also one can manage arbitrary amount of such
858          MIDI instrument maps and assign each sampler channel individually
859          a certain map, so that i.e. separation of normal instruments and
860          drumkits is possible
861        - new notification events for tracking changes to audio/MIDI devices,
862          MIDI instrument maps, MIDI instruments, FX sends, global volume.
863        - sampler was limited to load max. 200 instruments in the background
864          due to a constant size RingBuffer FIFO which is now replaced by a
865          dynamic (unlimited) size std::list FIFO
866        - added FX sends, these allow to route audio signals to arbitrary audio
867          output channels for being processed by external effect processors
868          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
869          controllers
870        - global (sampler wide) volume can now be controlled at runtime
871        - Implemented new, improved notification system
872        - fixed compilation errors regarding OSX
873          (patch by Toshi Nagata)
874        - implemented instruments database
875        - added support for escape sequences to the instruments database
876        - added highly experimental support for on-the-fly instrument editing
877          within the sampler's process (by using instrument editor plugins),
878          you'll notice the new "Registered instrument editors:" message on
879          startup, added a new LSCP command:
880          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
881          to spawn a matching instrument editor for the instrument on the
882          given sampler channel, the plugin path can be overridden at compile
883          time with ./configure --enable-plugin-dir=/some/dir
884        - added experimental code for synchronizing instrument editors hosted
885          in the sampler's process to safely edit instruments while playing
886          without a crash (hopefully) by either suspending single regions
887          wherever possible or if unavoidable whole engine(s)
888        - fixed several issues in fundamental "Thread" class: set scheduling
889          policy and priority on thread level, set a minimum stack size for
890          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
891          threads simply inherited properties of starting thread instead of
892          setting their own policy and priority
893        - minor fix in our automatic stack trace mechanism on crashes, the
894          main process did not wait for the stack trace process to finish
895          its output
896        - fixed some minor memory leaks
897        - reenabled assembly features support, at the moment only for
898          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
899        - minor assembly fix in x86 features detection (don't use the PIC
900          register, to avoid relocations in the text segment at runtime)
901        - POSIX callback functions of Thread.h are hidden
902    
903      * MIDI driver:
904        - dispatch bank select (MSB and LSB) messages
905    
906      * audio driver:
907        - the ALSA audio output driver parameters now reflect the correct
908          parameter value ranges for the respective selected sound card
909          (patch by Till Wimmer, a bit fixed and extended)
910    
911      * Gigasampler format engine:
912        - if a filter is used and EG2 finishes before EG1, let the voice
913          die when EG2 has finished (this fixes a problem with clicks and
914          voice starvation for some gigs)
915        - playback is no longer disabled during instrument loading
916        - all notes playing on a channel that changes its instrument keep
917          playing with the old instrument until they get a note off
918          command
919        - EG fix: a release value of zero could cause noises or crash
920        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
921        - EG fine tuning: when attack is zero the EG starts at a level
922          above max sustain level, which means that there is a decay phase
923          even if sustain is 100%
924        - more EG fixes: the level could sometimes go below zero and cause
925          noises or crashes
926        - minor fix of EGDecay (patch by Toshi Nagata)
927        - fixed compiler error when --enable-override-filter-type was
928          supplied to the configure script (fixes #46)
929        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
930          instead of a fix value
931        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
932          127 (solo mode) only kill voices if the respective mode really
933          changed
934    
935      * LSCP server:
936        - fixed compile time error for old Bison versions
937          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
938        - parser now supports extended ASCII character set
939          (up to ASCII code 255, i.e. includes now umlauts and accents)
940        - filename arguments in LSCP commands now allow to use escape
941          sequences, that is directly literal as one of: \', \", \\, \n, \r,
942          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
943          code value like \xf2) (fixes bug #24)
944        - the following LSCP commands now also support escape sequences for at
945          least one of their text-based parameters (i.e. name, description):
946          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
947          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
948          "SET DB_INSTRUMENT_DIRECTORY NAME",
949          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
950          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
951          "FIND DB_INSTRUMENT_DIRECTORIES"
952        - returns verbose syntax errors (line and column where syntax error
953          occured, the unexpected character and the actually expected, possible
954          character(s), the latter only if less than 5 possibilities)
955        - made sure that LSCP syntax is not affected by gigedit locale
956          settings
957        - bugfix regarding strings parameter lists: all comma separated lists
958          of strings were treated as being one string containing commas
959          (fixes #57)
960    
961      * Bug fixes:
962        - fixed crash occurring on certain LSCP scripts (Bug 39)
963        - another thread safety fix for lscp "load engine" and "set
964          channel audio output device"
965        - fixed a crash which occurs when reassigning the same engine
966          on a sampler channel with connected MIDI device
967        - fixed a crash which occurs when changing the number of ports of a MIDI
968          device connected to a sampler channel to number less then or equal
969          to the index of the port to which the sampler channel is connected.
970        - The previous bindings were not been disconnected when altering
971          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
972          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
973        - The active stream/voice count statistic was incorrect.
974        - notification events were not been sent for some sampler
975          channel changes
976        - added default min and max values to restrict the number of allowed
977          audio output channels and MIDI input ports
978        - the connection to the PCM interface is now closed when destroying
979          an audio output device
980        - files with slash in their path or filename could not be loaded
981    
982      * test cases:
983        - updated and fixed (haven't been touched in a while)
984    
985    Version 0.4.0 (24 November 2006)
986    
987      * packaging changes:
988        - changed deprecated copyright attribute to license; added ldconfig
989          to post-(un)install steps; added devel package for liblinuxsampler;
990          to linuxsampler.spec (RPM)
991        - install necessary development header files for allowing 3rd party
992          applications to link against liblinuxsampler
993        - liblinuxsampler's API documentation can be generated with 'make docs'
994          (Doxygen required)
995        - added benchmark to automatically detect the best triangle LFO
996          implementation (currently either an integer math solution or a
997          di-harmonic approximation), automatic detection can be overriden
998          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
999          configure script argument though (mandatory for cross-compilation)
1000        - do not automatically pick optimized gcc flags if the user already
1001          provided some on his own (as CXXFLAGS)
1002        - added compile time option to disable processing of All-Notes-Off MIDI
1003          messages
1004        - added compile time options to allow disabling the various audio and
1005          MIDI drivers
1006        - fixed automatic GCC CPU switch detection on PPC
1007          (patch by Ebrahim Mayat)
1008    
1009      * Gigasampler format engine:
1010        - extensive synthesis optimization
1011          (reimplementation of EGs and LFO(s), removed synthesis parameter
1012          prerendering and the synthesis parameter matrix in general, splitting
1013          each audio fragment into subfragments now where each subfragment uses
1014          constant pitch and filter coefficients. The volume coefficient is
1015          linearly interpolated inside a subfragment, unless
1016          --disable-interpolate-volume is set.)
1017        - fine tuning of the EG modulation parameters
1018        - improved filter cutoff calculation by adding support for the
1019          following gig parameters: Cutoff freq (used when no cutoff
1020          controller is defined), Control invert, Minimum cutoff, Velocity
1021          curve and Velocity range. The keyboard tracking now scales
1022          cutoff frequency instead of resonance.
1023        - added support for gig parameter Resonance.
1024        - fixed bug in sysex handling (patch by Juan Linietsky)
1025        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1026          which can be overridden with --enable-global-attenuation
1027        - EG fixes: made the length of "attack hold" stage more
1028          accurate. Release stage can now start before attack stage
1029          ends. Cancel release didn't work when sustain was zero. Attack
1030          time now has a minimal value to prevent clicks.
1031        - fixed pitch changes larger than one octave
1032        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1033        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1034          all modes can be altered via standard GM messages, that is CC5 for
1035          altering portamento time, CC65 for enabling / disabling portamento
1036          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1037        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1038          parameter) and crossfade
1039        - added support for the "attenuation controller threshold" gig
1040          parameter
1041        - added smoothing of volume changes caused by control change
1042          messages
1043        - sample loop parameters are now taken from the DimensionRegion
1044          instead of the wave chunk
1045        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1046          not equal to a power of two
1047        - reimplementation of the filter algorithm. The new filter is more
1048          accurate and supports all gig filter types, including bandreject
1049          and lowpass turbo.
1050        - real support for 24 bit samples - samples are not truncated to
1051          16 bits anymore
1052        - support for aftertouch (channel pressure, not polyphonic
1053          aftertouch)
1054        - LFO1 behaviour fixed (dampening from max volume instead of
1055          amplifying from 0)
1056    
1057      * LSCP server:
1058        - fixed application exit on broken pipe error (fixes bug #20)
1059        - fixed the notification messages delay due to lack of
1060          network activity (fixes bug #26)
1061        - fixed parser bug which occured on space(s) within device parameters
1062          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1063    
1064      * audio driver:
1065        - added aRts audio output driver (by no means RT safe)
1066    
1067      * MIDI driver:
1068        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1069          messages several times instead of once
1070        - API extension for MIDI drivers which already supply exact time stamps
1071          for events (i.e. for offline rendering based MIDI drivers)
1072        - added checks for bad MIDI data
1073    
1074      * linuxsampler application:
1075        - show available sampler engine types on startup
1076    
1077      * general changes:
1078        - support for muting sampler channels and solo mode of the same, two new
1079          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1080          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1081          introduced for this, the behavior is the same like on a mixer console
1082          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1083          --enable-process-muted-channels which can be used to enable the
1084          processing of muted channels.
1085        - support for sostenuto pedal
1086        - support for monitoring the total number of active voices
1087          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1088          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1089        - fixed some memory management errors
1090        - fixed some concurrency problems that could lead to crashes when
1091          LSCP commands were executed
1092        - fixed crash when instrument loading failed previously on the same
1093          sampler channel (fixes bug #36)
1094    
1095    Version 0.3.3 (15 July 2005)
1096    
1097      * packaging changes:
1098        - fixed compilation with gcc 4.0
1099    
1100      * Gigasampler format engine:
1101        - LFO preprocessing was performed even though the respective LFO was
1102          disabled by the instrument patch (minor efficiency fix)
1103        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1104          for volume ramp downs in the same fragment (needed for current voice
1105          stealing implementation) then simply inform the user with a warning
1106          about possible click sounds and reduce the volume ramp down
1107          appropriately instead of cancelling the audio device connection
1108    
1109    Version 0.3.2 (24 June 2005)
1110    
1111    * packaging changes:    * packaging changes:
1112      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
1113        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
1114        - hand-crafted assembly optimization code can be disabled with
1115          './configure --disable-asm' (definitely not recommended)
1116        - fixed 'make dist' rule to include all necessary files
1117        - require automake (>= 1.5) for 'make -f Makefile.cvs'
1118          (due to 'dist-bzip2' automake option)
1119    
1120      * Gigasampler format engine:
1121        - support for the gig parameters for "release velocity response" curves
1122        - fine tuning of the EGADSR envelope
1123        - volume of release triggered samples now depends on note-on velocity,
1124          note length and gig parameter "release trigger decay" instead of
1125          note-off velocity.
1126        - revised voice stealing
1127          (fixes crash and endless loop caused by voice stealing)
1128        - don't reset scale tuning on instrument or audio output device change
1129        - handle key group conflicts right at the beginning of each fragment
1130          instead of when the respective voice is actually launched
1131          (fixes undefined behavior if stolen voices belonged to a key group -
1132          this case was followed by a "killed voice survived" error message)
1133        - fixed minor issue with null/silence samples
1134          (those stole voices even though they don't need a voice at all which
1135          resulted in "voice stealing didn't work out" messages)
1136        - don't reset volume, pan, pitch and MIDI controller values on
1137          instrument or audio output device change
1138    
1139      * LSCP server:
1140        - fixed some crashes (patch by Grigor Iliev, fixes #19)
1141        - fixed LSCP event "CHANNEL_INFO" notification
1142          (e.g. did not notify on volume changes or MIDI program change events)
1143    
1144      * linuxsampler application:
1145        - added command line parameters --lscp-addr and --lscp-port to override
1146          default IP address and port of LSCP server
1147
