4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when

9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)

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

149        - fine-tuned the default velocity curve
150        - added support for transpose
151        - fixed crash when using sw_down/up
152        - improved logic for sw_lokey/hikey/up/down/last
153        - added more v1 aliases to parser
154        - reduced memory usage for sfz data

292          after each "#include", only after the main file is parsed
293        - bugfix: line numbers in error messages were wrong after "#include"
294    
295      * SoundFont format engine:
296        - Initial implementation (not usable yet)
297        - RT-safeness: avoid malloc in audio thread
298        - fixed a bug that could cause voice stealing to fail

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

447        - Implemented built-in script function "set_controller()".
448        - Added extended script VM for the Gigasampler/GigaStudio format sampler
449          engine, which extends the general instrument script VM with Giga format

481        - minor valgrind fixes
482        - fixed crash which occurred when changing an already deployed sampler
483          channel to a different engine type
484        - fixed crash when deleting a sampler channel or changing engine
485          type while an instrument load was in progress
486        - bugfix: playing a note while changing the instrument could cause
487          a crash, or give "Handing back unknown region" error messages
488        - bugfix: calling SET VOICES (which Fantasia does on start and
489          refresh) could cause instruments to be unloaded
490        - Mac OS X: fixed name collision of enum in EffectControl and
491          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
492        - Mac OS X: fixed hanging threads
493        - Windows: disabled the previous thread fix on non-Mac systems, as
494          it caused hanging threads on Windows
495        - Fixed possible crashes due to corrupted MIDI/audio device list
496          after MIDI/audio device creation failure
497        - When creating MIDI instrument map entries with "PERSISTENT" type, the
498          instruments were uselessly precached with zero samples, however it still
499          took the full preloading time and on 1st program change the respective
500          instrument was completely reloaded again.
501        - fixed handling of rapid bank select and program change messages
502          sent to the same sampler channel (patch from the Open Octave
503          project, slightly adjusted)
504        - fixed crash when trying to create an effect instance with controls
505          which min and/or max values depend on the sample rate

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