9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin

18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with

22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)

27        - fixed building with C++11
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
38      * general changes:
39        - Refactoring: moved the independent code from
40          the Gigasampler format engine to base classes
41        - command line option '--profile' is currently disabled, since the
42          respective profiling code is currently broken
43        - Introduced support for optional environment variable
44          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45          where the sampler shall look for instrument editor plugins
46          (patch by Luis Garrido, slightly modified).
47        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50          note (in this implementation of the sampler its simply hard routed to
51          the 1st effect send of the sampler channel, no matter what the actual
52          effect type is)
53        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54          note (in this implementation of the sampler its simply hard routed to
55          the 2nd effect send of the sampler channel, no matter what the actual
56          effect type is)
57        - implemented support for internal LADSPA effects
58        - raised limit of program change queue from 100 to 512
59          (as suggested by Alex Stone)
60        - implemented sine LFO, pulse LFO and saw LFO
61        - experimental support for per voice equalization
62        - added command line option --exec-after-init
63        - Introduced new C++ API method:
64          EngineChannel::InstrumentFileName(int index)
65          allowing to retrieve the whole list of files used for the loaded
66          instrument on an engine channel (a.k.a. part). Some GigaStudio
67          instruments for example are splitted over several files like
68          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69        - Added new C++ API method Sampler::GetGlobalMaxVoices().
70        - Added new C++ API method Sampler::GetGlobalMaxStreams().
71        - Added new C++ API method Sampler::SetGlobalMaxVoices().
72        - Added new C++ API method Sampler::SetGlobalMaxStreams().
73        - Various "const" and "restrict" optimizations.
74        - all engines: add pan CC value to instrument pan parameter before
75          applying panning, instead of using two separate pan functions in
76          series (#182)
77        - added a lock guard class for exception safe mutex handling and
78          used it everywhere appropriate
79        - Immediately apply scale tuning changes to active voices.
80        - Exposed scale tuning to C++ API (along to the already existing standard
81          SysEx way).
82        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83          and broken for ppc64. (Seq_cst loads and stores are actually not
84          used in LS, so the bug wasn't noticable.)
85        - lsatomic.h: added ARMv7 support
86        - Added support for multiple MIDI input ports per sampler channel (and
87          added various new C++ methods for this new feature / design change, old
88          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89          as deprecated but are still there and should provide full behavior
90          backward compatibility).
91        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92          unsafe and caused compilation error with clang 2.x).
93        - Bugfix: only process the latest MIDI program change event.
94        - Introducing the LSCP shell, which provides convenient control of the
95          sampler from the command line by providing LSCP aware features.
97      * Gigasampler format engine:
98        - implemented the "round robin keyboard" dimension
99        - fixed round robin and random dimensions for cases when number of
100          dimension zones is not a power of two
101        - made round robin use a counter for each region instead of each
102          key
103        - bugfix: pitch LFO controller "internal+aftertouch" was broken
104        - bugfix: filter keyboard tracking was broken
105        - filter performance fix (an unnecessary copy was made of the
106          filter parameters in each sub fragment)
107        - handle special case when pan parameter in gig file has max or
108          min value
109        - Exclusive Groups: don't ever stop voices of the same note,
110          doesn't sound naturally with a drumkit
111        - fixed EG1 modulation when attack or release is zero
113      * SFZ format engine:
114        - Initial implementation (not usable yet)
115        - added support for v2 multiple stage envelope generators
116        - added a fine-tuned v1 envelope generator instead of using the
117          one from the gig engine
118        - fixed memory leak and memory handling errors
119        - added support for trigger=first, trigger=legato and sw_previous
120        - allow non-numerical key values ("C#4" for example)
121        - "key" opcode now sets pitch_keycenter too
122        - fixed error when unloading instrument with same sample used by
123          multiple regions

284        - VST bugfix: If the host called resume() before and after
285          changing sample rate or block size, the number of channels was
286          incorrectly set to two. This caused silence in Cubase 5.
287        - save engine type (gig, sfz or sf2) in plugin state
288        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
289          64 bit Windows
290        - AU: changed number of output channels from one stereo to 16
291          stereo
292        - VST: made it possible to build the VST plugin for Mac

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

319        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
320          the ALSA sequencer client name
321        - removed limit of maximum amount of MIDI ports per MIDI device, since
322          there is no reason for this limit
323        - MME: fixed memory handling bug found with cppcheck
324        - MME: removed compiler warning
325        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
326          which allows to retrieve the list of CoreMIDI clients / ports and to connect
327          to them a la JACK, via the usual sampler APIs
328        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
329          the driver will automatically connect to other CoreMIDI clients' ports
330          (e.g. external MIDI devices being attached to the Mac)
331        - added support for MIDI note on velocity filter
332        - CoreMIDI: fixed memory deallocation error
333        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

345          RT context.
346        - ASIO driver: removed compiler warnings
347        - CoreAudio: fixed minor error handling bug
348        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

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

433        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
434          introduced in previous fix)
435        - fixed crash when a channel received a program change while
436          playing a note in a key group
437        - fixed erroneous error message piping in VoiceBase.h
438          (labelled "Disk stream not available in time")
439        - Update effects on sample rate & period size changes (to avoid
440          crashes and noise on such transitions).
441        - ignore missing LADSPA paths without ignoring valid LADSPA paths
442          (fixes #208)
444    Version 1.0.0 (31 July 2009)
446      * packaging changes:
447        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
448          causing e.g. the libgig test to fail when
449          "./configure --disable-jack-driver" was used
450          (patch by Alexis Ballier)
451        - fixed compilation with gcc 4.3
452        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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

922        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
923          which can be overridden with --enable-global-attenuation
924        - EG fixes: made the length of "attack hold" stage more
925          accurate. Release stage can now start before attack stage
926          ends. Cancel release didn't work when sustain was zero. Attack
927          time now has a minimal value to prevent clicks.
928        - fixed pitch changes larger than one octave
929        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
930        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
931          all modes can be altered via standard GM messages, that is CC5 for
932          altering portamento time, CC65 for enabling / disabling portamento
933          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
934        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
935          parameter) and crossfade

937          parameter
938        - added smoothing of volume changes caused by control change
939          messages
940        - sample loop parameters are now taken from the DimensionRegion
941          instead of the wave chunk
942        - fixed keyswitching for v3 gigs with a number of keyswitch splits
943          not equal to a power of two
944        - reimplementation of the filter algorithm. The new filter is more
945          accurate and supports all gig filter types, including bandreject
946          and lowpass turbo.
947        - real support for 24 bit samples - samples are not truncated to
948          16 bits anymore
949        - support for aftertouch (channel pressure, not polyphonic
950          aftertouch)
951        - LFO1 behaviour fixed (dampening from max volume instead of
952          amplifying from 0)
