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

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

300          the plugin was loaded a second time (#174)
301        - plugin bugfix: instrument loading hang when the plugin was
302          loaded a second time (this time it's for Linux and Mac, previous
303          similar fix was for Windows)
304        - thread safety fixes for the instrument loading thread
305        - LV2: use the new lv2 package if present
306        - VST: try to open Fantasia automatically on Linux and Mac too (on
307          Linux, the Fantasia jar should be placed in <prefix>/share/java)
308        - VST: fixed crashes on Linux Ardour and EnergyXT
309        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
310          port and audio channel routing for DSSI plugins are now visible.
311        - LV2: use urid and atom extensions instead of deprecated uri-map
312          and event
313        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
314        - LV2: changed number of output channels to 16 stereo, just like
315          the VST and AU plugins
316        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
317        - LV2: made LV2 plugin buildable on Windows and Mac
318        - VST: implemented retrieval and switching of programs using the
319          sampler's internal MIDI instrument mapping system
320    
321      * MIDI driver:
322        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
323          the ALSA sequencer client name
324        - removed limit of maximum amount of MIDI ports per MIDI device, since
325          there is no reason for this limit
326        - MME: fixed memory handling bug found with cppcheck
327        - MME: removed compiler warning
328        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
329          which allows to retrieve the list of CoreMIDI clients / ports and to connect
330          to them a la JACK, via the usual sampler APIs
331        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
332          the driver will automatically connect to other CoreMIDI clients' ports

353          for audio device parameter "SAMPLERATE" (fixes #166).
354

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

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

460        - minor fix in configure for mmsystem.h detection on MinGW
461        - Windows: look for editor plugins and Fantasia using base
462          directory of liblinuxsampler dll (look in the same directory and one
463          directory above)
464        - configure script fix: removed unconditional use of SSE
465        - fixed building with sqlite installed in a non-standard directory
466        - when cross-compiling, don't try to create instruments.db
467        - fix for new mingw-w64 version, which has usleep
468    
469      * general changes:
470        - bugfix: on some POSIX systems instrument editor plugins refused to
471          load as we used a non-portable Linux specific struct field
472          (fixes bug #70, patch by Ronald Baljeu)
473        - fixed endless loop which occured when loading an instrument editor
474          plugin DLL on Windows systems failed
475        - fixed memory leaks that occurred when liblinuxsampler was unloaded
476        - optimized the SynchronizedConfig class so it doesn't wait
477          unnecessarily long after an update
478        - added support for notifying instrument editors on note-on / note-off
479          events (e.g. to highlight the pressed keys on the virtual keyboard
480          of gigedit)
481        - added support for triggering notes by instrument editors (see above)
482        - be verbose on DLL load errors (on Linux)
483        - fixed di-harmonic triangle LFO implementation (this LFO implementation
484          is only used by very few systems, most pick the int math
485          implementation, which is usually faster)
486        - fixes for audio drivers with varying buffer sizes
487        - experimental support for running LinuxSampler as a DSSI, LV2 and
488          VST plugin
489        - notification events for stream/voice count statistics are now sent
490          only when there are actual changes
491        - added memory ordering constraints to improve stability on
492          multi-core and multi-cpu systems
493        - maximum voices and disk streams can now be altered at runtime
494        - fixed CPU feature detection on x86_64 (maybe fixes #108)
495        - automatic stacktrace mechanism is now turned off by default and can
496          be switched on by command line option "--stacktrace" (the automatic
497          stacktrace mechanism seems to be broken on most systems at the moment)
498        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
499          a pointer to the launched InstrumentEditor object
500        - added optional 3rd party user data parameter for following
501          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
502          InstrumentEditor::Launch(),
503          InstrumentManager::LaunchInstrumentEditor()
504        - theoretical fix: made SynchronizedConfig follow C++0x memory
505          model more strictly
506        - fixes for using large audio device buffers
507        - Windows: add the installation directory to the DLL search path
508          when loading an editor plugin (solves problems with VST and
509          gigedit on systems with other GTK versions installed)
510        - updated linuxsampler man page
511    
512      * audio driver:
513        - removed the nonsense audio channel constraint (which was hard coded to
514          max. 100 audio channels) for most audio drivers
515        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
516          opposed to the LSCP specs
517        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
518          reflected the wrong value
519        - fixed a memory management bug in ASIO driver
520        - Makefile fix: JACK_CFLAGS wasn't used
521        - JACK: use jack_client_open instead of the deprecated
522          jack_client_new
523        - added (experimental) CoreAudio driver
524        - applied old fixes to the ASIO driver that were included in the
525          previous binary release but accidentally never committed to CVS
526          (fixes #117)
527        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
528          win64)
529        - VST: added support for sample rate and buffer size changes
530        - VST: close editor (Fantasia) when the VST is removed
531        - VST: avoid opening Fantasia more than once for each VST instance
532        - VST: export main function as "main" on Linux too (fix for
533          energyXT)
534        - VST: changed number of output channels from one stereo to 16
535          stereo
536        - added channel routing, fxsends and midi maps to the settings
537          stored in the plugin state
538        - performance optimization of AudioChannel::MixTo() and
539          AudioChannel::CopyTo() methods using GCC vector exensions
540          (if available)
541        - ASIO fixes: avoid initializing the device twice, avoid throwing
542          exception when getting parameters from a disconnected device
543    
544      * MIDI driver:
545        - added JACK MIDI driver
546        - dispatch bank select as ordinary CC as well, the user might seriously
547          want to (mis)use it for some purpose ("fixed" in all current MIDI
548          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
549        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
550          CoreMidi or AU
551        - fixed mingw-w64 compilation error in MME driver
552        - made program change handling in MIDI thread real-time safe by
553          moving the logic to a non-RT thread
554        - fixed minor memory leak in ALSA driver
555    
556      * instruments database:
557        - avoid time consuming samples scanning when adding instruments
558          to the instruments database
559        - added support for handling lost files in the instruments database
560        - Implemented option for adding instruments in separate directories
561          in the instruments database
562          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
563        - work-around for missing fnmatch function on Windows to make
564          instrument database compilable
565        - added instrument database support on Windows
566          works with both standalone mode and VST plugin.
567          the instruments DB file is located in
568          %USERPROFILE%\.linuxsampler\instruments.db which allows different
569          databases for each windows user
570          if no DB is present it automatically creates the .linuxsampler subdir
571          and then creates an empty DB
572        - fixed recursive import, which was broken on Windows
573    
574      * Gigasampler format engine:
575        - fixed a memory leak that could happen when a channel was deleted
576          while notes were playing
577        - made it possible to load an instrument even if the audio thread
578          isn't running
579        - added partial support for the "Controller Triggered" MIDI rule,
580          enough for piano gigs with pedal noise samples
581        - minor fix: only mark FX sends as being modified if really the
582          respective FX send MIDI controller was used
583        - added support for GM global device volume SysEx message
584          (can be selected at compile time to either apply globally to the
585          whole sampler [default] or only to the sampler channels that are
586          connected to the respective MIDI input port the SysEx message arrived
587          on)
588        - bugfix: notes triggered at position 0 in the audio buffer were
589          sometimes wrongly killed in the same buffer, causing no sound to
590          be played
591        - added support for chromatic / drumkit mode Roland GS Sysex message
592          which is usally used to switch a part between chromatic sounds and
593          drumkit sounds (as opposed to their common default setting of MIDI
594          part 10 being a drumkit part and all other ones chromatic parts), in
595          LS however one can switch between the first 16 MIDI instrument maps
596          defined for the sampler
597        - made it possible to create multiple sample channels even if the
598          audio thread isn't running
599        - fixed crash when removing channel with active voices (#116)
600        - bugfix: on sample reference changes (instrument editor), only
601          un-cache the respective sample if it's really not used by any
602          sampler engine anymore
603        - re-cache samples in case they were changed by an instrument editor,
604          e.g. when a sample was added while playing (#82)
605        - fixed hanging notes which occured when note-off event had the exact
606          same time stamp as the voice's note-on event and occured both in the
607          same audio fragment cycle (fixes bug #112)
608        - added support for the "fine tune" and "pitch bend range"
609          instrument-level gig parameters
610        - fixed minor artifacts in pitch bend handling
611        - added support for GS Reset SysEx message
612        - allow gig files to use unlimited downward pitch shifting
613        - added a limit check for upward pitch shifting
614        - bugfix: sometimes, when playing a note twice fast, the second
615          note was silent
616        - fixed crash happening when a pitch bend event arrived at the
617          same time a new instrument was loading
618    
619      * LSCP server:
620        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
621          react on MIDI data arriving on certain sampler channels (so far only
622          Note-On and Note-Off events are sent via this LSCP event)
623        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
624          react on MIDI data arriving on certain MIDI input devices (so far only
625          Note-On and Note-Off events are sent via this LSCP event)
626        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
627          SET DB_INSTRUMENT FILE_PATH
628        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
629          frontends to send MIDI messages to specific sampler channel
630        - added two additional fields to GET FILE INSTRUMENT INFO command -
631          KEY_BINDINGS and KEYSWITCH_BINDINGS
632        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
633          was incorrect
634        - Optimized the retrieval of the MIDI instrument mappings
635        - added new LSCP command "SET VOICES" to globally alter the maximum
636          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
637          be triggered respectively
638        - added new LSCP command "SET STREAMS" to globally alter the maximum
639          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
640          which will be triggered respectively
641        - bugfix: retry if "select" returns EINTR (this fixes a crash when
642          a gigedit file dialog is opened)
643        - close all connections when LSCPServer is deleted
644        - hard close of all sockets on exit
645        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
646          driver
647    
648      * Bug fixes:
649        - fixed a crash which occurs when removing a sampler channel waiting
650          to start instrument loading after another channel
651        - fixed a crash which occurs when removing a sampler channel with
652          instrument loading in progress (bug #113)
653        - fixed termination caused by uncaught exception when adding MIDI
654          instrument with PERSISTENT load mode
655        - fixed possible iterator invalidations when resetting the sampler
656        - fixed memory leaks when issuing the following LSCP commands:
657          GET AUDIO_OUTPUT_DRIVER INFO
658          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
659          GET MIDI_INPUT_DRIVER INFO
660          GET MIDI_INPUT_DRIVER_PARAMETER INFO
661        - fixed possible compilation error when sqlite is not present
662        - fixed orphaned pointers when setting maximum voices limit (bug #118)
663        - fixed crash when changing the audio output device of a sampler
664          channel with loaded instrument and start playing notes
665        - fixed endless loop in Engine::SuspendAll() (bug #120)
666        - fixed a low-level atomic load function that was broken on 64-bit
667          PowerPC, which probably could cause crashes on that platform
668        - fixed a memory management error which could cause a crash when a
669          plugin was unloaded
670        - bugfix: two private structs had the same name, which could cause
671          problems if the linker chose the wrong constructor
672        - fixed low-level ConditionServer usage bug that caused lockups on
673          Windows
674    
675    
676    Version 0.5.1 (6 December 2007)
677    
678      * packaging changes:
679        - added autoconf checks for pthread library
680        - added autoconf check for pthread bug found on certain NPTL-enabled
681          glibc versions (see Gentoo bug report #194076)
682        - added autoconf checks for MS Windows
683    
684      * general changes:
685        - bugfix: the thread used by an editor plugin didn't die when the
686          editor closed
687        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
688          out all the space. operator--() did not apply size_mask after
689          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
690          order to avoid problems with the _NonVolatileReader functions.
691        - bugfix: Stream.h: added a missing divide by BytesPerSample in
692          GetWriteSpace(). Since this function is currently only used in
693          the stream's qsort() compare function, it didn't trigger any
694          bugs.
695        - Resampler.h, Synthesizer.h: cubic interpolation now works in
696          24bit mode too. Faster method to read 24bit words on little
697          endian machines (x86): replaced 3 byte reads + shifts with a 1
698          unaligned 32bit read and shift
699        - experimental support for MS Windows (MIDI input via MME, AUDIO
700          output via ASIO)
701        - made handling of SIGINT signal (Ctrl-C) a bit more robust
702        - support for monitoring the total number of active disk streams
703          (new LSCP commands: GET TOTAL_STREAM_COUNT,
704          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
705    
706      * AUDIO driver:
707        - added Windows ASIO low latency audio driver
708    
709      * MIDI driver:
710        - added MME Windows MIDI driver
711    
712      * LSCP server:
713        - added support for Windows style path / filenames, however with
714          forward slash path separators instead of backslash
715          (i.e. "C:/foo/bar.gig")
716        - allow naughty liblscp to send non-string device parameters within
717          apostrophes as well
718        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
719          "LIST FILE INSTRUMENTS <file>" and
720          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
721          about an arbitrary instrument file on the system where the sampler is
722          running on
723    
724    Version 0.5.0 (15 October 2007)
725    
726      * packaging changes:
727        - config.h is not going to be installed along with liblinuxsampler's
728          API header files anymore
729        - only the API relevant header (and source) files will be exported to
730          the Doxygen API documentation (explicitly listed in Doxyfile.in)
731        - added completely new XCode project files for Mac OSX which is now
732          capable to execute our autoconf environment, thus no need anymore
733          to maintain the compile time configuration file (osx/version.h) for
734          OSX manually (patch by Toshi Nagata)
735        - fixed buggy boolean --enable-foo / --disable-foo configure script
736          parameters
737        - global.h now only covers global definitions that are needed for the
738          C++ API header files, all implementation internal global definitions
739          are now in global_private.h
740        - atomic.h is not exposed to the C++ API anymore
741        - no need to include config.h anymore for using LS's API header files
742        - fixed warnings in API doc generation
743    
744      * general changes:
745        - replaced the old, confusing MIDI program change mechanism by a
746          flexible MIDI instrument mapper which allows to map arbitrary
747          (MIDI bank, MIDI program) pairs with arbitrary
748          (engine type, instrument file, file index) triplets which will be
749          loaded on the respective channel when such MIDI program change
750          messages arrive, beside that, each entry allows to define a life-time
751          strategy for the instrument, so the user can define whether the
752          instrument should i.e. be permanently loaded (to be able to switch
753          quickly among sounds) or i.e. loaded just on demand when the
754          respective program change arrives (to safe RAM space), as well as a
755          global volume factor for each entry, so the user can adjust the volume
756          dynamic of his mapped instrument collection without having to modify
757          the instrument files, also one can manage arbitrary amount of such
758          MIDI instrument maps and assign each sampler channel individually
759          a certain map, so that i.e. separation of normal instruments and
760          drumkits is possible
761        - new notification events for tracking changes to audio/MIDI devices,
762          MIDI instrument maps, MIDI instruments, FX sends, global volume.
763        - sampler was limited to load max. 200 instruments in the background
764          due to a constant size RingBuffer FIFO which is now replaced by a
765          dynamic (unlimited) size std::list FIFO
766        - added FX sends, these allow to route audio signals to arbitrary audio
767          output channels for being processed by external effect processors
768          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
769          controllers
770        - global (sampler wide) volume can now be controlled at runtime
771        - Implemented new, improved notification system
772        - fixed compilation errors regarding OSX
773          (patch by Toshi Nagata)
774        - implemented instruments database
775        - added support for escape sequences to the instruments database
776        - added highly experimental support for on-the-fly instrument editing
777          within the sampler's process (by using instrument editor plugins),
778          you'll notice the new "Registered instrument editors:" message on
779          startup, added a new LSCP command:
780          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
781          to spawn a matching instrument editor for the instrument on the
782          given sampler channel, the plugin path can be overridden at compile
783          time with ./configure --enable-plugin-dir=/some/dir
784        - added experimental code for synchronizing instrument editors hosted
785          in the sampler's process to safely edit instruments while playing
786          without a crash (hopefully) by either suspending single regions
787          wherever possible or if unavoidable whole engine(s)
788        - fixed several issues in fundamental "Thread" class: set scheduling
789          policy and priority on thread level, set a minimum stack size for
790          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
791          threads simply inherited properties of starting thread instead of
792          setting their own policy and priority
793        - minor fix in our automatic stack trace mechanism on crashes, the
794          main process did not wait for the stack trace process to finish
795          its output
796        - fixed some minor memory leaks
797        - reenabled assembly features support, at the moment only for
798          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
799        - minor assembly fix in x86 features detection (don't use the PIC
800          register, to avoid relocations in the text segment at runtime)
801        - POSIX callback functions of Thread.h are hidden
802    
803      * MIDI driver:
804        - dispatch bank select (MSB and LSB) messages
805    
806      * audio driver:
807        - the ALSA audio output driver parameters now reflect the correct
808          parameter value ranges for the respective selected sound card
809          (patch by Till Wimmer, a bit fixed and extended)
810    
811      * Gigasampler format engine:
812        - if a filter is used and EG2 finishes before EG1, let the voice
813          die when EG2 has finished (this fixes a problem with clicks and
814          voice starvation for some gigs)
815        - playback is no longer disabled during instrument loading
816        - all notes playing on a channel that changes its instrument keep
817          playing with the old instrument until they get a note off
818          command
819        - EG fix: a release value of zero could cause noises or crash
820        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
821        - EG fine tuning: when attack is zero the EG starts at a level
822          above max sustain level, which means that there is a decay phase
823          even if sustain is 100%
824        - more EG fixes: the level could sometimes go below zero and cause
825          noises or crashes
826        - minor fix of EGDecay (patch by Toshi Nagata)
827        - fixed compiler error when --enable-override-filter-type was
828          supplied to the configure script (fixes #46)
829        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
830          instead of a fix value
831        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
832          127 (solo mode) only kill voices if the respective mode really
833          changed
834    
835      * LSCP server:
836        - fixed compile time error for old Bison versions
837          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
838        - parser now supports extended ASCII character set
839          (up to ASCII code 255, i.e. includes now umlauts and accents)
840        - filename arguments in LSCP commands now allow to use escape
841          sequences, that is directly literal as one of: \', \", \\, \n, \r,
842          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
843          code value like \xf2) (fixes bug #24)
844        - the following LSCP commands now also support escape sequences for at
845          least one of their text-based parameters (i.e. name, description):
846          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
847          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
848          "SET DB_INSTRUMENT_DIRECTORY NAME",
849          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
850          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
851          "FIND DB_INSTRUMENT_DIRECTORIES"
852        - returns verbose syntax errors (line and column where syntax error
853          occured, the unexpected character and the actually expected, possible
854          character(s), the latter only if less than 5 possibilities)
855        - made sure that LSCP syntax is not affected by gigedit locale
856          settings
857        - bugfix regarding strings parameter lists: all comma separated lists
858          of strings were treated as being one string containing commas
859          (fixes #57)
860    
861      * Bug fixes:
862        - fixed crash occurring on certain LSCP scripts (Bug 39)
863        - another thread safety fix for lscp "load engine" and "set
864          channel audio output device"
865        - fixed a crash which occurs when reassigning the same engine
866          on a sampler channel with connected MIDI device
867        - fixed a crash which occurs when changing the number of ports of a MIDI
868          device connected to a sampler channel to number less then or equal
869          to the index of the port to which the sampler channel is connected.
870        - The previous bindings were not been disconnected when altering
871          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
872          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
873        - The active stream/voice count statistic was incorrect.
874        - notification events were not been sent for some sampler
875          channel changes
876        - added default min and max values to restrict the number of allowed
877          audio output channels and MIDI input ports
878        - the connection to the PCM interface is now closed when destroying
879          an audio output device
880        - files with slash in their path or filename could not be loaded
881    
882      * test cases:
883        - updated and fixed (haven't been touched in a while)
884    
885    Version 0.4.0 (24 November 2006)
886    
887      * packaging changes:
888        - changed deprecated copyright attribute to license; added ldconfig
889          to post-(un)install steps; added devel package for liblinuxsampler;
890          to linuxsampler.spec (RPM)
891        - install necessary development header files for allowing 3rd party
892          applications to link against liblinuxsampler
893        - liblinuxsampler's API documentation can be generated with 'make docs'
894          (Doxygen required)
895        - added benchmark to automatically detect the best triangle LFO
896          implementation (currently either an integer math solution or a
897          di-harmonic approximation), automatic detection can be overriden
898          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
899          configure script argument though (mandatory for cross-compilation)
900        - do not automatically pick optimized gcc flags if the user already
901          provided some on his own (as CXXFLAGS)
902        - added compile time option to disable processing of All-Notes-Off MIDI
903          messages
904        - added compile time options to allow disabling the various audio and
905          MIDI drivers
906        - fixed automatic GCC CPU switch detection on PPC
907          (patch by Ebrahim Mayat)
908    
909      * Gigasampler format engine:
910        - extensive synthesis optimization
911          (reimplementation of EGs and LFO(s), removed synthesis parameter
912          prerendering and the synthesis parameter matrix in general, splitting
913          each audio fragment into subfragments now where each subfragment uses
914          constant pitch and filter coefficients. The volume coefficient is
915          linearly interpolated inside a subfragment, unless
916          --disable-interpolate-volume is set.)
917        - fine tuning of the EG modulation parameters
918        - improved filter cutoff calculation by adding support for the
919          following gig parameters: Cutoff freq (used when no cutoff
920          controller is defined), Control invert, Minimum cutoff, Velocity
921          curve and Velocity range. The keyboard tracking now scales
922          cutoff frequency instead of resonance.
923        - added support for gig parameter Resonance.
924        - fixed bug in sysex handling (patch by Juan Linietsky)
925        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
926          which can be overridden with --enable-global-attenuation
927        - EG fixes: made the length of "attack hold" stage more
928          accurate. Release stage can now start before attack stage
929          ends. Cancel release didn't work when sustain was zero. Attack
930          time now has a minimal value to prevent clicks.
931        - fixed pitch changes larger than one octave
932        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
933        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
934          all modes can be altered via standard GM messages, that is CC5 for
935          altering portamento time, CC65 for enabling / disabling portamento
936          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
937        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
938          parameter) and crossfade
939        - added support for the "attenuation controller threshold" gig
940          parameter
941        - added smoothing of volume changes caused by control change
942          messages
943        - sample loop parameters are now taken from the DimensionRegion
944          instead of the wave chunk
945        - fixed keyswitching for v3 gigs with a number of keyswitch splits
946          not equal to a power of two
947        - reimplementation of the filter algorithm. The new filter is more
948          accurate and supports all gig filter types, including bandreject
949          and lowpass turbo.
950        - real support for 24 bit samples - samples are not truncated to
951          16 bits anymore
952        - support for aftertouch (channel pressure, not polyphonic
953          aftertouch)
954        - LFO1 behaviour fixed (dampening from max volume instead of
955          amplifying from 0)
956    
957      * LSCP server:
958        - fixed application exit on broken pipe error (fixes bug #20)
959        - fixed the notification messages delay due to lack of
960          network activity (fixes bug #26)
961        - fixed parser bug which occured on space(s) within device parameters
962          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
963    
964      * audio driver:
965        - added aRts audio output driver (by no means RT safe)
966    
967      * MIDI driver:
968        - fixed legacy sysex code which caused dispatching of MIDI SysEx
969          messages several times instead of once
970        - API extension for MIDI drivers which already supply exact time stamps
971          for events (i.e. for offline rendering based MIDI drivers)
972        - added checks for bad MIDI data
973    
974      * linuxsampler application:
975        - show available sampler engine types on startup
976    
977      * general changes:
978        - support for muting sampler channels and solo mode of the same, two new
979          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
980          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
981          introduced for this, the behavior is the same like on a mixer console
982          (patch by Grigor Iliev, a bit adjusted). Also added configure option
983          --enable-process-muted-channels which can be used to enable the
984          processing of muted channels.
985        - support for sostenuto pedal
986        - support for monitoring the total number of active voices
987          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
988          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
989        - fixed some memory management errors
990        - fixed some concurrency problems that could lead to crashes when
991          LSCP commands were executed
992        - fixed crash when instrument loading failed previously on the same
993          sampler channel (fixes bug #36)
994    
995    Version 0.3.3 (15 July 2005)
996    
997      * packaging changes:
998        - fixed compilation with gcc 4.0
999    
1000      * Gigasampler format engine:
1001        - LFO preprocessing was performed even though the respective LFO was
1002          disabled by the instrument patch (minor efficiency fix)
1003        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1004          for volume ramp downs in the same fragment (needed for current voice
1005          stealing implementation) then simply inform the user with a warning
1006          about possible click sounds and reduce the volume ramp down
1007          appropriately instead of cancelling the audio device connection
1008    
1009    Version 0.3.2 (24 June 2005)
1010    
1011      * packaging changes:
1012        - updated autotools build files to compile on OS X
1013          (conditional compilation of CoreMIDI and MidiShare drivers)
1014        - hand-crafted assembly optimization code can be disabled with
1015          './configure --disable-asm' (definitely not recommended)
1016        - fixed 'make dist' rule to include all necessary files
1017        - require automake (>= 1.5) for 'make -f Makefile.cvs'
1018          (due to 'dist-bzip2' automake option)
1019    
1020      * Gigasampler format engine:
1021        - support for the gig parameters for "release velocity response" curves
1022        - fine tuning of the EGADSR envelope
1023        - volume of release triggered samples now depends on note-on velocity,
1024          note length and gig parameter "release trigger decay" instead of
1025          note-off velocity.
1026        - revised voice stealing
1027          (fixes crash and endless loop caused by voice stealing)
1028        - don't reset scale tuning on instrument or audio output device change
1029        - handle key group conflicts right at the beginning of each fragment
1030          instead of when the respective voice is actually launched
1031          (fixes undefined behavior if stolen voices belonged to a key group -
1032          this case was followed by a "killed voice survived" error message)
1033        - fixed minor issue with null/silence samples
1034          (those stole voices even though they don't need a voice at all which
1035          resulted in "voice stealing didn't work out" messages)
1036        - don't reset volume, pan, pitch and MIDI controller values on
1037          instrument or audio output device change
1038    
1039      * LSCP server:
1040        - fixed some crashes (patch by Grigor Iliev, fixes #19)
1041        - fixed LSCP event "CHANNEL_INFO" notification
1042          (e.g. did not notify on volume changes or MIDI program change events)
1043    
1044      * linuxsampler application:
1045        - added command line parameters --lscp-addr and --lscp-port to override
1046          default IP address and port of LSCP server
1047    
1048  Version 0.3.1 (24 May 2005)  Version 0.3.1 (24 May 2005)
