31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37        - enabled automake 'subdir-objects' option and moved external
38          source references (vst, au, asio) from makefiles to cpp files,
39          in order to get rid of warnings from automake 1.14
40    
41      * general changes:
42        - Refactoring: moved the independent code from
43          the Gigasampler format engine to base classes
44        - command line option '--profile' is currently disabled, since the
45          respective profiling code is currently broken
46        - Introduced support for optional environment variable
47          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48          where the sampler shall look for instrument editor plugins
49          (patch by Luis Garrido, slightly modified).
50        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53          note (in this implementation of the sampler its simply hard routed to
54          the 1st effect send of the sampler channel, no matter what the actual
55          effect type is)
56        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57          note (in this implementation of the sampler its simply hard routed to
58          the 2nd effect send of the sampler channel, no matter what the actual
59          effect type is)
60        - implemented support for internal LADSPA effects
61        - raised limit of program change queue from 100 to 512
62          (as suggested by Alex Stone)
63        - implemented sine LFO, pulse LFO and saw LFO
64        - experimental support for per voice equalization
65        - added command line option --exec-after-init
66        - Introduced new C++ API method:
67          EngineChannel::InstrumentFileName(int index)
68          allowing to retrieve the whole list of files used for the loaded
69          instrument on an engine channel (a.k.a. part). Some GigaStudio
70          instruments for example are splitted over several files like
71          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72        - Added new C++ API method Sampler::GetGlobalMaxVoices().
73        - Added new C++ API method Sampler::GetGlobalMaxStreams().
74        - Added new C++ API method Sampler::SetGlobalMaxVoices().
75        - Added new C++ API method Sampler::SetGlobalMaxStreams().
76        - Various "const" and "restrict" optimizations.
77        - all engines: add pan CC value to instrument pan parameter before
78          applying panning, instead of using two separate pan functions in
79          series (#182)
80        - added a lock guard class for exception safe mutex handling and
81          used it everywhere appropriate
82        - Immediately apply scale tuning changes to active voices.
83        - Exposed scale tuning to C++ API (along to the already existing standard
84          SysEx way).
85        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86          and broken for ppc64. (Seq_cst loads and stores are actually not
87          used in LS, so the bug wasn't noticable.)
88        - lsatomic.h: added ARMv7 support
89        - Added support for multiple MIDI input ports per sampler channel (and
90          added various new C++ methods for this new feature / design change, old
91          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92          as deprecated but are still there and should provide full behavior
93          backward compatibility).
94        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95          unsafe and caused compilation error with clang 2.x).
96        - Bugfix: only process the latest MIDI program change event.
97        - Introducing the LSCP shell, which provides convenient control of the
98          sampler from the command line by providing LSCP aware features.
99        - VirtualMidiDevice: Added support for program change.
100        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101        - VirtualMidiDevice: Added support for pitch bend.
102    
103      * Gigasampler format engine:
104        - implemented the "round robin keyboard" dimension
105        - fixed round robin and random dimensions for cases when number of
106          dimension zones is not a power of two
107        - made round robin use a counter for each region instead of each
108          key
109        - bugfix: pitch LFO controller "internal+aftertouch" was broken
110        - bugfix: filter keyboard tracking was broken
111        - filter performance fix (an unnecessary copy was made of the
112          filter parameters in each sub fragment)
113        - handle special case when pan parameter in gig file has max or
114          min value
115        - Exclusive Groups: don't ever stop voices of the same note,
116          doesn't sound naturally with a drumkit
117        - fixed EG1 modulation when attack or release is zero
118

280          after each "#include", only after the main file is parsed
281        - bugfix: line numbers in error messages were wrong after "#include"
282    
283      * SoundFont format engine:
284        - Initial implementation (not usable yet)
285        - RT-safeness: avoid malloc in audio thread

294        - Listen to all interfaces on Mac OS X (INADDR_ANY)
295        - VST bugfix: If the host called resume() before and after
296          changing sample rate or block size, the number of channels was
297          incorrectly set to two. This caused silence in Cubase 5.
298        - save engine type (gig, sfz or sf2) in plugin state
299        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
300          64 bit Windows
301        - AU: changed number of output channels from one stereo to 16
302          stereo
303        - VST: made it possible to build the VST plugin for Mac

308          the plugin was loaded a second time (#174)
309        - plugin bugfix: instrument loading hang when the plugin was
310          loaded a second time (this time it's for Linux and Mac, previous
311          similar fix was for Windows)
312        - thread safety fixes for the instrument loading thread
313        - LV2: use the new lv2 package if present
314        - VST: try to open Fantasia automatically on Linux and Mac too (on
315          Linux, the Fantasia jar should be placed in <prefix>/share/java)
316        - VST: fixed crashes on Linux Ardour and EnergyXT
317        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
318          port and audio channel routing for DSSI plugins are now visible.
319        - LV2: use urid and atom extensions instead of deprecated uri-map
320          and event
321        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
322        - LV2: changed number of output channels to 16 stereo, just like
323          the VST and AU plugins
324        - LV2: fixed save/restore of SFZ state (patch by David Robillard)

327          sampler's internal MIDI instrument mapping system
328    
329      * MIDI driver:
330        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
331          the ALSA sequencer client name
332        - removed limit of maximum amount of MIDI ports per MIDI device, since
333          there is no reason for this limit
334        - MME: fixed memory handling bug found with cppcheck
335        - MME: removed compiler warning
336        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
337          which allows to retrieve the list of CoreMIDI clients / ports and to connect
338          to them a la JACK, via the usual sampler APIs
339        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
340          the driver will automatically connect to other CoreMIDI clients' ports
341          (e.g. external MIDI devices being attached to the Mac)
342        - added support for MIDI note on velocity filter
343        - CoreMIDI: fixed memory deallocation error
344        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
345          virtual keyboards in frontends / instrument editors being stuck.
346        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
347        - Implemented missing handling of MIDI "running status".
348        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
349        - MME bugfix: driver wasn't closed properly
350    
351      * audio driver:

399        - provide comprehensive error messages on LSCP syntax errors
400          (suggesting expected next non-terminal symbols)
401    
402      * LSCP shell:
403        - Added support for auto correction of obvious and trivial syntax mistakes.
404        - Added support for auto completion by tab key.
405        - Show currently available auto completion while typing.
406        - Added support for browsing command history with up / down keys.
407        - Show all possible next symbols immediately right to the current command
408          line while typing (no double tab required for this feature, as it would
409          be the case in other shells).
410        - Added support for moving cursor left/right with arrow keys.
411        - Added support for built-in LSCP reference documentation, which will
412          automatically show the relevant LSCP reference section on screen as soon
413          as one specific LSCP command was detected while typing on the command
414          line.
415    
416      * Bug fixes:
417        - Fixed crash which may occur when MIDI key + transpose is out of range
418        - minor valgrind fixes
419        - fixed crash which occurred when changing an already deployed sampler
420          channel to a different engine type
421        - fixed crash when deleting a sampler channel or changing engine
422          type while an instrument load was in progress
423        - bugfix: playing a note while changing the instrument could cause
424          a crash, or give "Handing back unknown region" error messages
425        - bugfix: calling SET VOICES (which Fantasia does on start and
426          refresh) could cause instruments to be unloaded
427        - Mac OS X: fixed name collision of enum in EffectControl and
428          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
429        - Mac OS X: fixed hanging threads
430        - Windows: disabled the previous thread fix on non-Mac systems, as
431          it caused hanging threads on Windows
432        - Fixed possible crashes due to corrupted MIDI/audio device list
433          after MIDI/audio device creation failure
434        - When creating MIDI instrument map entries with "PERSISTENT" type, the
435          instruments were uselessly precached with zero samples, however it still
436          took the full preloading time and on 1st program change the respective
437          instrument was completely reloaded again.
438        - fixed handling of rapid bank select and program change messages
439          sent to the same sampler channel (patch from the Open Octave
440          project, slightly adjusted)
441        - fixed crash when trying to create an effect instance with controls
442          which min and/or max values depend on the sample rate
443        - fixed bug #162
444        - bugfix: LADSPA_PATH was not evaluated correctly when containing
445          multiple paths (#165)
446        - thread safety fixes for the instrument loading thread
447        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
448          (#176)
449        - more thread safety fixes for the instrument loading thread
450        - sfz/sf2 engine: fixed crash when using small audio fragment size
451        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
452        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
453          introduced in previous fix)
454        - fixed crash when a channel received a program change while
455          playing a note in a key group
456        - fixed erroneous error message piping in VoiceBase.h
457          (labelled "Disk stream not available in time")
458        - Update effects on sample rate & period size changes (to avoid
459          crashes and noise on such transitions).
460        - ignore missing LADSPA paths without ignoring valid LADSPA paths
461          (fixes #208)
462        - Fixed bug in LSCP grammar definition which caused a statement like
463          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
464          practically irrelevant, however it caused problems with the new LSCP
465          shell's auto completion feature).
466    
467    Version 1.0.0 (31 July 2009)
468    
469      * packaging changes:
470        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
471          causing e.g. the libgig test to fail when
472          "./configure --disable-jack-driver" was used
473          (patch by Alexis Ballier)
474        - fixed compilation with gcc 4.3
475        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
476        - fixed configure so it detects x86_64 (#107)
477        - fixes for building with newer MinGW versions
478        - fix for building with bison 2.4 (#111)
479        - fixed building with libgig installed in a non-standard directory
480        - minor fix in configure for mmsystem.h detection on MinGW
481        - Windows: look for editor plugins and Fantasia using base
482          directory of liblinuxsampler dll (look in the same directory and one
483          directory above)
484        - configure script fix: removed unconditional use of SSE
485        - fixed building with sqlite installed in a non-standard directory
486        - when cross-compiling, don't try to create instruments.db
487        - fix for new mingw-w64 version, which has usleep
488    
489      * general changes:
490        - bugfix: on some POSIX systems instrument editor plugins refused to
491          load as we used a non-portable Linux specific struct field
492          (fixes bug #70, patch by Ronald Baljeu)
493        - fixed endless loop which occured when loading an instrument editor
494          plugin DLL on Windows systems failed
495        - fixed memory leaks that occurred when liblinuxsampler was unloaded
496        - optimized the SynchronizedConfig class so it doesn't wait
497          unnecessarily long after an update
498        - added support for notifying instrument editors on note-on / note-off
499          events (e.g. to highlight the pressed keys on the virtual keyboard
500          of gigedit)
501        - added support for triggering notes by instrument editors (see above)
502        - be verbose on DLL load errors (on Linux)
503        - fixed di-harmonic triangle LFO implementation (this LFO implementation
504          is only used by very few systems, most pick the int math
505          implementation, which is usually faster)
506        - fixes for audio drivers with varying buffer sizes
507        - experimental support for running LinuxSampler as a DSSI, LV2 and
508          VST plugin
509        - notification events for stream/voice count statistics are now sent
510          only when there are actual changes
511        - added memory ordering constraints to improve stability on
512          multi-core and multi-cpu systems
513        - maximum voices and disk streams can now be altered at runtime
514        - fixed CPU feature detection on x86_64 (maybe fixes #108)
515        - automatic stacktrace mechanism is now turned off by default and can
516          be switched on by command line option "--stacktrace" (the automatic
517          stacktrace mechanism seems to be broken on most systems at the moment)
518        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
519          a pointer to the launched InstrumentEditor object
520        - added optional 3rd party user data parameter for following
521          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
522          InstrumentEditor::Launch(),
523          InstrumentManager::LaunchInstrumentEditor()
524        - theoretical fix: made SynchronizedConfig follow C++0x memory
525          model more strictly
526        - fixes for using large audio device buffers
527        - Windows: add the installation directory to the DLL search path
528          when loading an editor plugin (solves problems with VST and
529          gigedit on systems with other GTK versions installed)
530        - updated linuxsampler man page
531    
532      * audio driver:
533        - removed the nonsense audio channel constraint (which was hard coded to
534          max. 100 audio channels) for most audio drivers
535        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
536          opposed to the LSCP specs
537        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
538          reflected the wrong value
539        - fixed a memory management bug in ASIO driver
540        - Makefile fix: JACK_CFLAGS wasn't used
541        - JACK: use jack_client_open instead of the deprecated
542          jack_client_new
543        - added (experimental) CoreAudio driver
544        - applied old fixes to the ASIO driver that were included in the
545          previous binary release but accidentally never committed to CVS
546          (fixes #117)
547        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
548          win64)
549        - VST: added support for sample rate and buffer size changes
550        - VST: close editor (Fantasia) when the VST is removed
551        - VST: avoid opening Fantasia more than once for each VST instance
552        - VST: export main function as "main" on Linux too (fix for
553          energyXT)
554        - VST: changed number of output channels from one stereo to 16
555          stereo
556        - added channel routing, fxsends and midi maps to the settings
557          stored in the plugin state
558        - performance optimization of AudioChannel::MixTo() and
559          AudioChannel::CopyTo() methods using GCC vector exensions
560          (if available)
561        - ASIO fixes: avoid initializing the device twice, avoid throwing
562          exception when getting parameters from a disconnected device
563    
564      * MIDI driver:
565        - added JACK MIDI driver
566        - dispatch bank select as ordinary CC as well, the user might seriously
567          want to (mis)use it for some purpose ("fixed" in all current MIDI
568          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
569        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
570          CoreMidi or AU
571        - fixed mingw-w64 compilation error in MME driver
572        - made program change handling in MIDI thread real-time safe by
573          moving the logic to a non-RT thread
574        - fixed minor memory leak in ALSA driver
575    
576      * instruments database:
577        - avoid time consuming samples scanning when adding instruments
578          to the instruments database
579        - added support for handling lost files in the instruments database
580        - Implemented option for adding instruments in separate directories
581          in the instruments database
582          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
583        - work-around for missing fnmatch function on Windows to make
584          instrument database compilable
585        - added instrument database support on Windows
586          works with both standalone mode and VST plugin.
587          the instruments DB file is located in
588          %USERPROFILE%\.linuxsampler\instruments.db which allows different
589          databases for each windows user
590          if no DB is present it automatically creates the .linuxsampler subdir
591          and then creates an empty DB
592        - fixed recursive import, which was broken on Windows
593    
594      * Gigasampler format engine:
595        - fixed a memory leak that could happen when a channel was deleted
596          while notes were playing
597        - made it possible to load an instrument even if the audio thread
598          isn't running
599        - added partial support for the "Controller Triggered" MIDI rule,
600          enough for piano gigs with pedal noise samples
601        - minor fix: only mark FX sends as being modified if really the
602          respective FX send MIDI controller was used
603        - added support for GM global device volume SysEx message
604          (can be selected at compile time to either apply globally to the
605          whole sampler [default] or only to the sampler channels that are
606          connected to the respective MIDI input port the SysEx message arrived
607          on)
608        - bugfix: notes triggered at position 0 in the audio buffer were
609          sometimes wrongly killed in the same buffer, causing no sound to
610          be played
611        - added support for chromatic / drumkit mode Roland GS Sysex message
612          which is usally used to switch a part between chromatic sounds and
613          drumkit sounds (as opposed to their common default setting of MIDI
614          part 10 being a drumkit part and all other ones chromatic parts), in
615          LS however one can switch between the first 16 MIDI instrument maps
616          defined for the sampler
617        - made it possible to create multiple sample channels even if the
618          audio thread isn't running
619        - fixed crash when removing channel with active voices (#116)
620        - bugfix: on sample reference changes (instrument editor), only
621          un-cache the respective sample if it's really not used by any
622          sampler engine anymore
623        - re-cache samples in case they were changed by an instrument editor,
624          e.g. when a sample was added while playing (#82)
625        - fixed hanging notes which occured when note-off event had the exact
626          same time stamp as the voice's note-on event and occured both in the
627          same audio fragment cycle (fixes bug #112)
628        - added support for the "fine tune" and "pitch bend range"
629          instrument-level gig parameters
630        - fixed minor artifacts in pitch bend handling
631        - added support for GS Reset SysEx message
632        - allow gig files to use unlimited downward pitch shifting
633        - added a limit check for upward pitch shifting
634        - bugfix: sometimes, when playing a note twice fast, the second
635          note was silent
636        - fixed crash happening when a pitch bend event arrived at the
637          same time a new instrument was loading
638    
639      * LSCP server:
640        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
641          react on MIDI data arriving on certain sampler channels (so far only
642          Note-On and Note-Off events are sent via this LSCP event)
643        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
644          react on MIDI data arriving on certain MIDI input devices (so far only
645          Note-On and Note-Off events are sent via this LSCP event)
646        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
647          SET DB_INSTRUMENT FILE_PATH
648        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
649          frontends to send MIDI messages to specific sampler channel
650        - added two additional fields to GET FILE INSTRUMENT INFO command -
651          KEY_BINDINGS and KEYSWITCH_BINDINGS
652        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
653          was incorrect
654        - Optimized the retrieval of the MIDI instrument mappings
655        - added new LSCP command "SET VOICES" to globally alter the maximum
656          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
657          be triggered respectively
658        - added new LSCP command "SET STREAMS" to globally alter the maximum
659          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
660          which will be triggered respectively
661        - bugfix: retry if "select" returns EINTR (this fixes a crash when
662          a gigedit file dialog is opened)
663        - close all connections when LSCPServer is deleted
664        - hard close of all sockets on exit
665        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
666          driver
667    
668      * Bug fixes:
669        - fixed a crash which occurs when removing a sampler channel waiting
670          to start instrument loading after another channel
671        - fixed a crash which occurs when removing a sampler channel with
672          instrument loading in progress (bug #113)
673        - fixed termination caused by uncaught exception when adding MIDI
674          instrument with PERSISTENT load mode
675        - fixed possible iterator invalidations when resetting the sampler
676        - fixed memory leaks when issuing the following LSCP commands:
677          GET AUDIO_OUTPUT_DRIVER INFO
678          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
679          GET MIDI_INPUT_DRIVER INFO
680          GET MIDI_INPUT_DRIVER_PARAMETER INFO
681        - fixed possible compilation error when sqlite is not present
682        - fixed orphaned pointers when setting maximum voices limit (bug #118)
683        - fixed crash when changing the audio output device of a sampler
684          channel with loaded instrument and start playing notes
685        - fixed endless loop in Engine::SuspendAll() (bug #120)
686        - fixed a low-level atomic load function that was broken on 64-bit
687          PowerPC, which probably could cause crashes on that platform
688        - fixed a memory management error which could cause a crash when a
689          plugin was unloaded
690        - bugfix: two private structs had the same name, which could cause
691          problems if the linker chose the wrong constructor
692        - fixed low-level ConditionServer usage bug that caused lockups on
693          Windows
694    
695    
696    Version 0.5.1 (6 December 2007)
697    
698      * packaging changes:
699        - added autoconf checks for pthread library
700        - added autoconf check for pthread bug found on certain NPTL-enabled
701          glibc versions (see Gentoo bug report #194076)
702        - added autoconf checks for MS Windows
703    
704      * general changes:
705        - bugfix: the thread used by an editor plugin didn't die when the
706          editor closed
707        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
708          out all the space. operator--() did not apply size_mask after
709          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
710          order to avoid problems with the _NonVolatileReader functions.
711        - bugfix: Stream.h: added a missing divide by BytesPerSample in
712          GetWriteSpace(). Since this function is currently only used in
713          the stream's qsort() compare function, it didn't trigger any
714          bugs.
715        - Resampler.h, Synthesizer.h: cubic interpolation now works in
716          24bit mode too. Faster method to read 24bit words on little
717          endian machines (x86): replaced 3 byte reads + shifts with a 1
718          unaligned 32bit read and shift
719        - experimental support for MS Windows (MIDI input via MME, AUDIO
720          output via ASIO)
721        - made handling of SIGINT signal (Ctrl-C) a bit more robust
722        - support for monitoring the total number of active disk streams
723          (new LSCP commands: GET TOTAL_STREAM_COUNT,
724          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
725    
726      * AUDIO driver:
727        - added Windows ASIO low latency audio driver
728    
729      * MIDI driver:
730        - added MME Windows MIDI driver
731    
732      * LSCP server:
733        - added support for Windows style path / filenames, however with
734          forward slash path separators instead of backslash
735          (i.e. "C:/foo/bar.gig")
736        - allow naughty liblscp to send non-string device parameters within
737          apostrophes as well
738        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
739          "LIST FILE INSTRUMENTS <file>" and
740          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
741          about an arbitrary instrument file on the system where the sampler is
742          running on
743    
744    Version 0.5.0 (15 October 2007)
745    
746      * packaging changes:
747        - config.h is not going to be installed along with liblinuxsampler's
748          API header files anymore
749        - only the API relevant header (and source) files will be exported to
750          the Doxygen API documentation (explicitly listed in Doxyfile.in)
751        - added completely new XCode project files for Mac OSX which is now
752          capable to execute our autoconf environment, thus no need anymore
753          to maintain the compile time configuration file (osx/version.h) for
754          OSX manually (patch by Toshi Nagata)
755        - fixed buggy boolean --enable-foo / --disable-foo configure script
756          parameters
757        - global.h now only covers global definitions that are needed for the
758          C++ API header files, all implementation internal global definitions
759          are now in global_private.h
760        - atomic.h is not exposed to the C++ API anymore
761        - no need to include config.h anymore for using LS's API header files
762        - fixed warnings in API doc generation
763    
764      * general changes:
765        - replaced the old, confusing MIDI program change mechanism by a
766          flexible MIDI instrument mapper which allows to map arbitrary
767          (MIDI bank, MIDI program) pairs with arbitrary
768          (engine type, instrument file, file index) triplets which will be
769          loaded on the respective channel when such MIDI program change
770          messages arrive, beside that, each entry allows to define a life-time
771          strategy for the instrument, so the user can define whether the
772          instrument should i.e. be permanently loaded (to be able to switch
773          quickly among sounds) or i.e. loaded just on demand when the
774          respective program change arrives (to safe RAM space), as well as a
775          global volume factor for each entry, so the user can adjust the volume
776          dynamic of his mapped instrument collection without having to modify
777          the instrument files, also one can manage arbitrary amount of such
778          MIDI instrument maps and assign each sampler channel individually
779          a certain map, so that i.e. separation of normal instruments and
780          drumkits is possible
781        - new notification events for tracking changes to audio/MIDI devices,
782          MIDI instrument maps, MIDI instruments, FX sends, global volume.
783        - sampler was limited to load max. 200 instruments in the background
784          due to a constant size RingBuffer FIFO which is now replaced by a
785          dynamic (unlimited) size std::list FIFO
786        - added FX sends, these allow to route audio signals to arbitrary audio
787          output channels for being processed by external effect processors
788          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
789          controllers
790        - global (sampler wide) volume can now be controlled at runtime
791        - Implemented new, improved notification system
792        - fixed compilation errors regarding OSX
793          (patch by Toshi Nagata)
794        - implemented instruments database
795        - added support for escape sequences to the instruments database
796        - added highly experimental support for on-the-fly instrument editing
797          within the sampler's process (by using instrument editor plugins),
798          you'll notice the new "Registered instrument editors:" message on
799          startup, added a new LSCP command:
800          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
801          to spawn a matching instrument editor for the instrument on the
802          given sampler channel, the plugin path can be overridden at compile
803          time with ./configure --enable-plugin-dir=/some/dir
804        - added experimental code for synchronizing instrument editors hosted
805          in the sampler's process to safely edit instruments while playing
806          without a crash (hopefully) by either suspending single regions
807          wherever possible or if unavoidable whole engine(s)
808        - fixed several issues in fundamental "Thread" class: set scheduling
809          policy and priority on thread level, set a minimum stack size for
810          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
811          threads simply inherited properties of starting thread instead of
812          setting their own policy and priority
813        - minor fix in our automatic stack trace mechanism on crashes, the
814          main process did not wait for the stack trace process to finish
815          its output
816        - fixed some minor memory leaks
817        - reenabled assembly features support, at the moment only for
818          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
819        - minor assembly fix in x86 features detection (don't use the PIC
820          register, to avoid relocations in the text segment at runtime)
821        - POSIX callback functions of Thread.h are hidden
822    
823      * MIDI driver:
824        - dispatch bank select (MSB and LSB) messages
825    
826      * audio driver:
827        - the ALSA audio output driver parameters now reflect the correct
828          parameter value ranges for the respective selected sound card
829          (patch by Till Wimmer, a bit fixed and extended)
830    
831      * Gigasampler format engine:
832        - if a filter is used and EG2 finishes before EG1, let the voice
833          die when EG2 has finished (this fixes a problem with clicks and
834          voice starvation for some gigs)
835        - playback is no longer disabled during instrument loading
836        - all notes playing on a channel that changes its instrument keep
837          playing with the old instrument until they get a note off
838          command
839        - EG fix: a release value of zero could cause noises or crash
840        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
841        - EG fine tuning: when attack is zero the EG starts at a level
842          above max sustain level, which means that there is a decay phase
843          even if sustain is 100%
844        - more EG fixes: the level could sometimes go below zero and cause
845          noises or crashes
846        - minor fix of EGDecay (patch by Toshi Nagata)
847        - fixed compiler error when --enable-override-filter-type was
848          supplied to the configure script (fixes #46)
849        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
850          instead of a fix value
851        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
852          127 (solo mode) only kill voices if the respective mode really
853          changed
854    
855      * LSCP server:
856        - fixed compile time error for old Bison versions
857          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
858        - parser now supports extended ASCII character set
859          (up to ASCII code 255, i.e. includes now umlauts and accents)
860        - filename arguments in LSCP commands now allow to use escape
861          sequences, that is directly literal as one of: \', \", \\, \n, \r,
862          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
863          code value like \xf2) (fixes bug #24)
864        - the following LSCP commands now also support escape sequences for at
865          least one of their text-based parameters (i.e. name, description):
866          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
867          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
868          "SET DB_INSTRUMENT_DIRECTORY NAME",
869          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
870          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
871          "FIND DB_INSTRUMENT_DIRECTORIES"
872        - returns verbose syntax errors (line and column where syntax error
873          occured, the unexpected character and the actually expected, possible
874          character(s), the latter only if less than 5 possibilities)
875        - made sure that LSCP syntax is not affected by gigedit locale
876          settings
877        - bugfix regarding strings parameter lists: all comma separated lists
878          of strings were treated as being one string containing commas
879          (fixes #57)
880    
881      * Bug fixes:
882        - fixed crash occurring on certain LSCP scripts (Bug 39)
883        - another thread safety fix for lscp "load engine" and "set
884          channel audio output device"
885        - fixed a crash which occurs when reassigning the same engine
886          on a sampler channel with connected MIDI device
887        - fixed a crash which occurs when changing the number of ports of a MIDI
888          device connected to a sampler channel to number less then or equal
889          to the index of the port to which the sampler channel is connected.
890        - The previous bindings were not been disconnected when altering
891          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
892          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
893        - The active stream/voice count statistic was incorrect.
894        - notification events were not been sent for some sampler
895          channel changes
896        - added default min and max values to restrict the number of allowed
897          audio output channels and MIDI input ports
898        - the connection to the PCM interface is now closed when destroying
899          an audio output device
900        - files with slash in their path or filename could not be loaded
901    
902      * test cases:
903        - updated and fixed (haven't been touched in a while)
904    
905    Version 0.4.0 (24 November 2006)
906    
907      * packaging changes:
908        - changed deprecated copyright attribute to license; added ldconfig
909          to post-(un)install steps; added devel package for liblinuxsampler;
910          to linuxsampler.spec (RPM)
911      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party

922        - added compile time option to disable processing of All-Notes-Off MIDI
923          messages
924        - added compile time options to allow disabling the various audio and
925          MIDI drivers
926        - fixed automatic GCC CPU switch detection on PPC
927          (patch by Ebrahim Mayat)
928    
929    * Gigasampler format engine:    * Gigasampler format engine:
930        - extensive synthesis optimization
931          (reimplementation of EGs and LFO(s), removed synthesis parameter
932          prerendering and the synthesis parameter matrix in general, splitting
933          each audio fragment into subfragments now where each subfragment uses
934          constant pitch and filter coefficients. The volume coefficient is
935          linearly interpolated inside a subfragment, unless
936          --disable-interpolate-volume is set.)
937      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters

942        cutoff frequency, not just resonance.        cutoff frequency instead of resonance.
943        - added support for gig parameter Resonance.
944        - fixed bug in sysex handling (patch by Juan Linietsky)
945        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
946          which can be overridden with --enable-global-attenuation
947        - EG fixes: made the length of "attack hold" stage more
948          accurate. Release stage can now start before attack stage
949          ends. Cancel release didn't work when sustain was zero. Attack
950          time now has a minimal value to prevent clicks.
951        - fixed pitch changes larger than one octave
952        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
953        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
954          all modes can be altered via standard GM messages, that is CC5 for
955          altering portamento time, CC65 for enabling / disabling portamento
956          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
957        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
958          parameter) and crossfade
959        - added support for the "attenuation controller threshold" gig
960          parameter
961        - added smoothing of volume changes caused by control change
962          messages
963        - sample loop parameters are now taken from the DimensionRegion
964          instead of the wave chunk
965        - fixed keyswitching for v3 gigs with a number of keyswitch splits
966          not equal to a power of two
967        - reimplementation of the filter algorithm. The new filter is more
968          accurate and supports all gig filter types, including bandreject
969          and lowpass turbo.
970        - real support for 24 bit samples - samples are not truncated to
971          16 bits anymore
972        - support for aftertouch (channel pressure, not polyphonic
973          aftertouch)
974        - LFO1 behaviour fixed (dampening from max volume instead of
975          amplifying from 0)
976    
977    * LSCP server:    * LSCP server:
978      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
979        - fixed the notification messages delay due to lack of
980          network activity (fixes bug #26)
981        - fixed parser bug which occured on space(s) within device parameters
982          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
983    
984      * audio driver:
985        - added aRts audio output driver (by no means RT safe)
986    
987      * MIDI driver:
988        - fixed legacy sysex code which caused dispatching of MIDI SysEx
989          messages several times instead of once
990        - API extension for MIDI drivers which already supply exact time stamps
991          for events (i.e. for offline rendering based MIDI drivers)
992        - added checks for bad MIDI data
993    
994      * linuxsampler application:
995        - show available sampler engine types on startup
996
