28        - build fix: ChangeFlagRelaxed.h was missing in makefile
29        - build fix: libsndfile compiler flags were missing in some
30          makefiles
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
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.
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
119      * SFZ format engine:

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

307          loaded a second time (this time it's for Linux and Mac, previous
308          similar fix was for Windows)
309        - thread safety fixes for the instrument loading thread
310        - LV2: use the new lv2 package if present
311        - VST: try to open Fantasia automatically on Linux and Mac too (on
312          Linux, the Fantasia jar should be placed in <prefix>/share/java)
313        - VST: fixed crashes on Linux Ardour and EnergyXT
314        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
315          port and audio channel routing for DSSI plugins are now visible.
316        - LV2: use urid and atom extensions instead of deprecated uri-map
317          and event
318        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
319        - LV2: changed number of output channels to 16 stereo, just like
320          the VST and AU plugins
321        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
322        - LV2: made LV2 plugin buildable on Windows and Mac
323        - VST: implemented retrieval and switching of programs using the
324          sampler's internal MIDI instrument mapping system
326      * MIDI driver:
327        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
328          the ALSA sequencer client name
329        - removed limit of maximum amount of MIDI ports per MIDI device, since
330          there is no reason for this limit
331        - MME: fixed memory handling bug found with cppcheck
332        - MME: removed compiler warning
333        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
334          which allows to retrieve the list of CoreMIDI clients / ports and to connect
335          to them a la JACK, via the usual sampler APIs
336        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
337          the driver will automatically connect to other CoreMIDI clients' ports
338          (e.g. external MIDI devices being attached to the Mac)
339        - added support for MIDI note on velocity filter
340        - CoreMIDI: fixed memory deallocation error
341        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
342          virtual keyboards in frontends / instrument editors being stuck.
343        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
344        - Implemented missing handling of MIDI "running status".
345        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
346        - MME bugfix: driver wasn't closed properly
348      * audio driver:
349        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
350        - JACK audio: react on sample rate changes.
351        - JACK audio: react on buffer size changes.
352        - JACK audio: jack_port_get_buffer() was cached and called outside
353          RT context.
354        - ASIO driver: removed compiler warnings
355        - CoreAudio: fixed minor error handling bug
356        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
357        - JACK audio: return the JACK server's current sample rate as default value
358          for audio device parameter "SAMPLERATE" (fixes #166).
360      * LSCP server:
361        - added support for sending MIDI CC messages via LSCP command
362          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
363        - added LSCP command "GET AVAILABLE_EFFECTS"
364        - added LSCP command "LIST AVAILABLE_EFFECTS"

391          <fx_send_id> <effect_chain> <chain_pos>"
392        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
393        - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",
396        - provide comprehensive error messages on LSCP syntax errors
397          (suggesting expected next non-terminal symbols)
399      * LSCP shell:
400        - Added support for auto correction of obvious and trivial syntax mistakes.
401        - Added support for auto completion by tab key.
402        - Show currently available auto completion while typing.
403        - Added support for browsing command history with up / down keys.
404        - Show all possible next symbols immediately right to the current command
405          line while typing (no double tab required for this feature, as it would
406          be the case in other shells).
407        - Added support for moving cursor left/right with arrow keys.
409      * Bug fixes:
410        - Fixed crash which may occur when MIDI key + transpose is out of range
411        - minor valgrind fixes

414        - fixed crash when deleting a sampler channel or changing engine
415          type while an instrument load was in progress
416        - bugfix: playing a note while changing the instrument could cause
417          a crash, or give "Handing back unknown region" error messages
418        - bugfix: calling SET VOICES (which Fantasia does on start and
419          refresh) could cause instruments to be unloaded
420        - Mac OS X: fixed name collision of enum in EffectControl and
421          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
422        - Mac OS X: fixed hanging threads
423        - Windows: disabled the previous thread fix on non-Mac systems, as
424          it caused hanging threads on Windows
425        - Fixed possible crashes due to corrupted MIDI/audio device list
426          after MIDI/audio device creation failure
427        - When creating MIDI instrument map entries with "PERSISTENT" type, the
428          instruments were uselessly precached with zero samples, however it still
429          took the full preloading time and on 1st program change the respective
430          instrument was completely reloaded again.
431        - fixed handling of rapid bank select and program change messages
432          sent to the same sampler channel (patch from the Open Octave
433          project, slightly adjusted)
434        - fixed crash when trying to create an effect instance with controls
435          which min and/or max values depend on the sample rate
436        - fixed bug #162

438          multiple paths (#165)
439        - thread safety fixes for the instrument loading thread
440        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
441          (#176)

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

937      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
938        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
939          which can be overridden with --enable-global-attenuation
940        - EG fixes: made the length of "attack hold" stage more
941          accurate. Release stage can now start before attack stage
942          ends. Cancel release didn't work when sustain was zero. Attack
943          time now has a minimal value to prevent clicks.
944        - fixed pitch changes larger than one octave
945        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
946        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
947          all modes can be altered via standard GM messages, that is CC5 for
948          altering portamento time, CC65 for enabling / disabling portamento
949          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
950        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
951          parameter) and crossfade

953          parameter
954        - added smoothing of volume changes caused by control change
955          messages
956        - sample loop parameters are now taken from the DimensionRegion
957          instead of the wave chunk
958        - fixed keyswitching for v3 gigs with a number of keyswitch splits
959          not equal to a power of two
960        - reimplementation of the filter algorithm. The new filter is more
961          accurate and supports all gig filter types, including bandreject
962          and lowpass turbo.
963        - real support for 24 bit samples - samples are not truncated to
964          16 bits anymore
965        - support for aftertouch (channel pressure, not polyphonic
966          aftertouch)
967        - LFO1 behaviour fixed (dampening from max volume instead of
968          amplifying from 0)
