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

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

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

326          the ALSA sequencer client name
327        - removed limit of maximum amount of MIDI ports per MIDI device, since
328          there is no reason for this limit
329        - MME: fixed memory handling bug found with cppcheck
330        - MME: removed compiler warning
331        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
332          which allows to retrieve the list of CoreMIDI clients / ports and to connect
333          to them a la JACK, via the usual sampler APIs
334        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
335          the driver will automatically connect to other CoreMIDI clients' ports
336          (e.g. external MIDI devices being attached to the Mac)
337        - added support for MIDI note on velocity filter
338        - CoreMIDI: fixed memory deallocation error
339        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
340          virtual keyboards in frontends / instrument editors being stuck.
341        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
342        - Implemented missing handling of MIDI "running status".
343        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
344        - MME bugfix: driver wasn't closed properly
345    
346      * audio driver:
347        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
348        - JACK audio: react on sample rate changes.
349        - JACK audio: react on buffer size changes.
350        - JACK audio: jack_port_get_buffer() was cached and called outside
351          RT context.
352        - ASIO driver: removed compiler warnings
353        - CoreAudio: fixed minor error handling bug
354        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
355        - JACK audio: return the JACK server's current sample rate as default value
356          for audio device parameter "SAMPLERATE" (fixes #166).
357    
358      * LSCP server:
359        - added support for sending MIDI CC messages via LSCP command
360          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

395          (suggesting expected next non-terminal symbols)
396    
397      * LSCP shell:
398        - Added support for auto correction of obvious and trivial syntax mistakes.
399        - Added support for auto completion by tab key.

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

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

910          messages
911        - added compile time options to allow disabling the various audio and
912          MIDI drivers
913        - fixed automatic GCC CPU switch detection on PPC
914          (patch by Ebrahim Mayat)
915    
916    * Gigasampler format engine:    * Gigasampler format engine:
917        - extensive synthesis optimization
918          (reimplementation of EGs and LFO(s), removed synthesis parameter
919          prerendering and the synthesis parameter matrix in general, splitting
920          each audio fragment into subfragments now where each subfragment uses
921          constant pitch and filter coefficients. The volume coefficient is
922          linearly interpolated inside a subfragment, unless
923          --disable-interpolate-volume is set.)
924      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters

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