# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
10      * packaging changes:
11        - removed unnecessary dependency to libuuid
12          (originated by libgig's usage of it)

16      * packaging changes:
17        - fixed building with newer MinGW-w64
18        - Mac OS X: support the new dir for Core Audio SDK
19        - Mac OS X: fixed building outside source directory
20        - made sure all source files for hostplugins are included when
21          doing "make dist"
22        - removed empty directories left from the cvs to svn migration
23        - fixed compilation with gcc 4.6.1
24        - another "make dist" fix, for the LV2 plugin
25        - made --enable-pthread-testcancel default on Mac OS X
26        - minor Makefile fix for building lscpparser when build and source
27          directories are separate
28        - Mac OS X: made it possible to specify plugin installation dir to

47        - fixed build error on newer MinGW
48        - support building with older jack versions
49        - support building with spaces in vst sdk path
50        - enabled automake 'subdir-objects' option and moved external
51          source references (vst, au, asio) from makefiles to cpp files,
52          in order to get rid of warnings from automake 1.14
54      * general changes:
55        - Refactoring: moved the independent code from
56          the Gigasampler format engine to base classes
57        - command line option '--profile' is currently disabled, since the
58          respective profiling code is currently broken
59        - Introduced support for optional environment variable
60          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
61          where the sampler shall look for instrument editor plugins
62          (patch by Luis Garrido, slightly modified).
63        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
64        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
65        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
66          note (in this implementation of the sampler its simply hard routed to
67          the 1st effect send of the sampler channel, no matter what the actual
68          effect type is)
69        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
70          note (in this implementation of the sampler its simply hard routed to
71          the 2nd effect send of the sampler channel, no matter what the actual
72          effect type is)
73        - implemented support for internal LADSPA effects
74        - raised limit of program change queue from 100 to 512
75          (as suggested by Alex Stone)
76        - implemented sine LFO, pulse LFO and saw LFO
77        - experimental support for per voice equalization
78        - added command line option --exec-after-init
79        - Introduced new C++ API method:
80          EngineChannel::InstrumentFileName(int index)
81          allowing to retrieve the whole list of files used for the loaded
82          instrument on an engine channel (a.k.a. part). Some GigaStudio
83          instruments for example are splitted over several files like
84          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
85        - Added new C++ API method Sampler::GetGlobalMaxVoices().
86        - Added new C++ API method Sampler::GetGlobalMaxStreams().
87        - Added new C++ API method Sampler::SetGlobalMaxVoices().
88        - Added new C++ API method Sampler::SetGlobalMaxStreams().
89        - Various "const" and "restrict" optimizations.
90        - all engines: add pan CC value to instrument pan parameter before
91          applying panning, instead of using two separate pan functions in
92          series (#182)
93        - added a lock guard class for exception safe mutex handling and
94          used it everywhere appropriate
95        - Immediately apply scale tuning changes to active voices.
96        - Exposed scale tuning to C++ API (along to the already existing standard
97          SysEx way).
98        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
99          and broken for ppc64. (Seq_cst loads and stores are actually not
100          used in LS, so the bug wasn't noticable.)
101        - lsatomic.h: added ARMv7 support
102        - Added support for multiple MIDI input ports per sampler channel (and
103          added various new C++ methods for this new feature / design change, old
104          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
105          as deprecated but are still there and should provide full behavior
106          backward compatibility).
107        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
108          unsafe and caused compilation error with clang 2.x).
109        - Bugfix: only process the latest MIDI program change event.
110        - Introducing the LSCP shell, which provides convenient control of the
111          sampler from the command line by providing LSCP aware features.
112        - VirtualMidiDevice: Added support for program change.
113        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
114        - VirtualMidiDevice: Added support for pitch bend.
115        - Aftertouch: extended API to explicitly handle channel pressure and
116          polyphonic key pressure events (so far polyphonic pressure was not
117          supported at all, and channel pressure was rerouted as CC128 but not
118          used so far).
119        - Added initial support for real-time instrument scripts. The script VM
120          code is shared by all sampler engine implemementations, however only the
121          gig file format currently provides support for storing instrument scripts
122          (as LinuxSampler extension to the original GigaStudio 4 format).
124      * Gigasampler format engine:
125        - implemented the "round robin keyboard" dimension
126        - fixed round robin and random dimensions for cases when number of
127          dimension zones is not a power of two
128        - made round robin use a counter for each region instead of each
129          key
130        - bugfix: pitch LFO controller "internal+aftertouch" was broken
131        - bugfix: filter keyboard tracking was broken
132        - filter performance fix (an unnecessary copy was made of the
133          filter parameters in each sub fragment)
134        - handle special case when pan parameter in gig file has max or
135          min value
136        - Exclusive Groups: don't ever stop voices of the same note,
137          doesn't sound naturally with a drumkit
138        - fixed EG1 modulation when attack or release is zero
139        - Fixed support for 'aftertouch' attenuation controller.
140        - Fixed crash that happened with velocity split sounds under certain
141          conditions (see also previous commit on libgig).
142        - fixed behaviour of filter LFO
144      * SFZ format engine:
145        - Initial implementation (not usable yet)

150        - added support for trigger=first, trigger=legato and sw_previous
151        - allow non-numerical key values ("C#4" for example)
152        - "key" opcode now sets pitch_keycenter too
153        - fixed error when unloading instrument with same sample used by
154          multiple regions

161        - added support for amp_veltrack and amp_velcurve_N
162        - fine-tuned the default velocity curve
163        - added support for transpose
164        - fixed crash when using sw_down/up
165        - improved logic for sw_lokey/hikey/up/down/last
166        - added more v1 aliases to parser
167        - reduced memory usage for sfz data
168        - RT-safeness: avoid malloc in audio thread
169        - fixed a bug that could cause voice stealing to fail
170        - optimized sample lookup
171        - improved support for exclusive groups (group, off_by and

305          after each "#include", only after the main file is parsed
306        - bugfix: line numbers in error messages were wrong after "#include"
307        - added support for float and 32 bit sample files
309      * SoundFont format engine:

321        - VST bugfix: If the host called resume() before and after
322          changing sample rate or block size, the number of channels was
323          incorrectly set to two. This caused silence in Cubase 5.
324        - save engine type (gig, sfz or sf2) in plugin state
325        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
326          64 bit Windows

334          the plugin was loaded a second time (#174)
335        - plugin bugfix: instrument loading hang when the plugin was
336          loaded a second time (this time it's for Linux and Mac, previous
337          similar fix was for Windows)
338        - thread safety fixes for the instrument loading thread
339        - LV2: use the new lv2 package if present
340        - VST: try to open Fantasia automatically on Linux and Mac too (on
341          Linux, the Fantasia jar should be placed in <prefix>/share/java)
342        - VST: fixed crashes on Linux Ardour and EnergyXT
343        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
344          port and audio channel routing for DSSI plugins are now visible.
345        - LV2: use urid and atom extensions instead of deprecated uri-map
346          and event
347        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

356        - Changed instrument editor plugin interface, providing additional
357          informations like the EngineChannel for which the instrument editor was
358          spawned for. This allows the instrument editors to interact more actively
359          with the sampler.
361      * MIDI driver:
362        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
363          the ALSA sequencer client name

365          there is no reason for this limit
366        - MME: fixed memory handling bug found with cppcheck
367        - MME: removed compiler warning
368        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
369          which allows to retrieve the list of CoreMIDI clients / ports and to connect
370          to them a la JACK, via the usual sampler APIs
371        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
372          the driver will automatically connect to other CoreMIDI clients' ports
373          (e.g. external MIDI devices being attached to the Mac)
374        - added support for MIDI note on velocity filter
375        - CoreMIDI: fixed memory deallocation error
376        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
377          virtual keyboards in frontends / instrument editors being stuck.
378        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
379        - Implemented missing handling of MIDI "running status".
380        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
381        - MME bugfix: driver wasn't closed properly
382        - CoreMIDI: automatically connect to all input sources by default (driver
383          parameter "AUTO_BIND").
384        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
385        - CoreMIDI: fixed minor memory leak
387      * audio driver:
388        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
389        - JACK audio: react on sample rate changes.
390        - JACK audio: react on buffer size changes.
391        - JACK audio: jack_port_get_buffer() was cached and called outside
392          RT context.
393        - ASIO driver: removed compiler warnings
394        - CoreAudio: fixed minor error handling bug
395        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
396        - JACK audio: return the JACK server's current sample rate as default value
397          for audio device parameter "SAMPLERATE" (fixes #166).
399      * LSCP server:
400        - added support for sending MIDI CC messages via LSCP command
401          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"
402        - added LSCP command "GET AVAILABLE_EFFECTS"
403        - added LSCP command "LIST AVAILABLE_EFFECTS"

436          (suggesting expected next non-terminal symbols)
438      * LSCP shell:
439        - Added support for auto correction of obvious and trivial syntax mistakes.
440        - Added support for auto completion by tab key.
441        - Show currently available auto completion while typing.
442        - Added support for browsing command history with up / down keys.
443        - Show all possible next symbols immediately right to the current command
444          line while typing (no double tab required for this feature, as it would
445          be the case in other shells).
446        - Added support for moving cursor left/right with arrow keys.
447        - Added support for built-in LSCP reference documentation, which will
448          automatically show the relevant LSCP reference section on screen as soon
449          as one specific LSCP command was detected while typing on the command
450          line.
452      * Real-time instrument scripts:

495        - Built-in script functions "ignore_event()", "note_off()" and
496          "gig_set_dim_zone()" now also accept an array of event IDs as argument
497          (i.e. return value of new script function "by_marks()").
498        - Pass/preserve polyphonic variable data from respective "note" event
499          handler to "release" event handler.
501      * Bug fixes:
502        - Fixed crash which may occur when MIDI key + transpose is out of range
503        - minor valgrind fixes
504        - fixed crash which occurred when changing an already deployed sampler
505          channel to a different engine type
506        - fixed crash when deleting a sampler channel or changing engine
507          type while an instrument load was in progress
508        - bugfix: playing a note while changing the instrument could cause
509          a crash, or give "Handing back unknown region" error messages
510        - bugfix: calling SET VOICES (which Fantasia does on start and
511          refresh) could cause instruments to be unloaded
512        - Mac OS X: fixed name collision of enum in EffectControl and
513          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
514        - Mac OS X: fixed hanging threads
515        - Windows: disabled the previous thread fix on non-Mac systems, as
516          it caused hanging threads on Windows
517        - Fixed possible crashes due to corrupted MIDI/audio device list
518          after MIDI/audio device creation failure
519        - When creating MIDI instrument map entries with "PERSISTENT" type, the
520          instruments were uselessly precached with zero samples, however it still
521          took the full preloading time and on 1st program change the respective
522          instrument was completely reloaded again.
523        - fixed handling of rapid bank select and program change messages
524          sent to the same sampler channel (patch from the Open Octave
525          project, slightly adjusted)
526        - fixed crash when trying to create an effect instance with controls
527          which min and/or max values depend on the sample rate

538          introduced in previous fix)
539        - fixed crash when a channel received a program change while
540          playing a note in a key group
541        - fixed erroneous error message piping in VoiceBase.h
542          (labelled "Disk stream not available in time")
543        - Update effects on sample rate & period size changes (to avoid
544          crashes and noise on such transitions).
545        - ignore missing LADSPA paths without ignoring valid LADSPA paths
546          (fixes #208)
547        - Fixed bug in LSCP grammar definition which caused a statement like
548          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
549          practically irrelevant, however it caused problems with the new LSCP
550          shell's auto completion feature).
551        - Fixed MIDI program change messages being ignored if quickly executed
552          after each other (fixes #231).
554    Version 1.0.0 (31 July 2009)
556      * packaging changes:
557        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
558          causing e.g. the libgig test to fail when
559          "./configure --disable-jack-driver" was used
560          (patch by Alexis Ballier)
561        - fixed compilation with gcc 4.3
562        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
563        - fixed configure so it detects x86_64 (#107)
564        - fixes for building with newer MinGW versions
565        - fix for building with bison 2.4 (#111)
566        - fixed building with libgig installed in a non-standard directory
567        - minor fix in configure for mmsystem.h detection on MinGW
568        - Windows: look for editor plugins and Fantasia using base
569          directory of liblinuxsampler dll (look in the same directory and one
570          directory above)
571        - configure script fix: removed unconditional use of SSE
572        - fixed building with sqlite installed in a non-standard directory
573        - when cross-compiling, don't try to create instruments.db
574        - fix for new mingw-w64 version, which has usleep
576      * general changes:
577        - bugfix: on some POSIX systems instrument editor plugins refused to
578          load as we used a non-portable Linux specific struct field
579          (fixes bug #70, patch by Ronald Baljeu)
580        - fixed endless loop which occured when loading an instrument editor
581          plugin DLL on Windows systems failed
582        - fixed memory leaks that occurred when liblinuxsampler was unloaded
583        - optimized the SynchronizedConfig class so it doesn't wait
584          unnecessarily long after an update
585        - added support for notifying instrument editors on note-on / note-off
586          events (e.g. to highlight the pressed keys on the virtual keyboard
587          of gigedit)
588        - added support for triggering notes by instrument editors (see above)
589        - be verbose on DLL load errors (on Linux)
590        - fixed di-harmonic triangle LFO implementation (this LFO implementation
591          is only used by very few systems, most pick the int math
592          implementation, which is usually faster)
593        - fixes for audio drivers with varying buffer sizes
594        - experimental support for running LinuxSampler as a DSSI, LV2 and
595          VST plugin
596        - notification events for stream/voice count statistics are now sent
597          only when there are actual changes
598        - added memory ordering constraints to improve stability on
599          multi-core and multi-cpu systems
600        - maximum voices and disk streams can now be altered at runtime
601        - fixed CPU feature detection on x86_64 (maybe fixes #108)
602        - automatic stacktrace mechanism is now turned off by default and can
603          be switched on by command line option "--stacktrace" (the automatic
604          stacktrace mechanism seems to be broken on most systems at the moment)
605        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
606          a pointer to the launched InstrumentEditor object
607        - added optional 3rd party user data parameter for following
608          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
609          InstrumentEditor::Launch(),
610          InstrumentManager::LaunchInstrumentEditor()
611        - theoretical fix: made SynchronizedConfig follow C++0x memory
612          model more strictly
613        - fixes for using large audio device buffers
614        - Windows: add the installation directory to the DLL search path
615          when loading an editor plugin (solves problems with VST and
616          gigedit on systems with other GTK versions installed)
617        - updated linuxsampler man page
619      * audio driver:
620        - removed the nonsense audio channel constraint (which was hard coded to
621          max. 100 audio channels) for most audio drivers
622        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
623          opposed to the LSCP specs
624        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
625          reflected the wrong value
626        - fixed a memory management bug in ASIO driver
627        - Makefile fix: JACK_CFLAGS wasn't used
628        - JACK: use jack_client_open instead of the deprecated
629          jack_client_new
630        - added (experimental) CoreAudio driver
631        - applied old fixes to the ASIO driver that were included in the
632          previous binary release but accidentally never committed to CVS
633          (fixes #117)
634        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
635          win64)
636        - VST: added support for sample rate and buffer size changes
637        - VST: close editor (Fantasia) when the VST is removed
638        - VST: avoid opening Fantasia more than once for each VST instance
639        - VST: export main function as "main" on Linux too (fix for
640          energyXT)
641        - VST: changed number of output channels from one stereo to 16
642          stereo
643        - added channel routing, fxsends and midi maps to the settings
644          stored in the plugin state
645        - performance optimization of AudioChannel::MixTo() and
646          AudioChannel::CopyTo() methods using GCC vector exensions
647          (if available)
648        - ASIO fixes: avoid initializing the device twice, avoid throwing
649          exception when getting parameters from a disconnected device
651      * MIDI driver:
652        - added JACK MIDI driver
653        - dispatch bank select as ordinary CC as well, the user might seriously
654          want to (mis)use it for some purpose ("fixed" in all current MIDI
655          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
656        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
657          CoreMidi or AU
658        - fixed mingw-w64 compilation error in MME driver
659        - made program change handling in MIDI thread real-time safe by
660          moving the logic to a non-RT thread
661        - fixed minor memory leak in ALSA driver
663      * instruments database:
664        - avoid time consuming samples scanning when adding instruments
665          to the instruments database
666        - added support for handling lost files in the instruments database
667        - Implemented option for adding instruments in separate directories
668          in the instruments database
669          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
670        - work-around for missing fnmatch function on Windows to make
671          instrument database compilable
672        - added instrument database support on Windows
673          works with both standalone mode and VST plugin.
674          the instruments DB file is located in
675          %USERPROFILE%\.linuxsampler\instruments.db which allows different
676          databases for each windows user
677          if no DB is present it automatically creates the .linuxsampler subdir
678          and then creates an empty DB
679        - fixed recursive import, which was broken on Windows
681      * Gigasampler format engine:
682        - fixed a memory leak that could happen when a channel was deleted
683          while notes were playing
684        - made it possible to load an instrument even if the audio thread
685          isn't running
686        - added partial support for the "Controller Triggered" MIDI rule,
687          enough for piano gigs with pedal noise samples
688        - minor fix: only mark FX sends as being modified if really the
689          respective FX send MIDI controller was used
690        - added support for GM global device volume SysEx message
691          (can be selected at compile time to either apply globally to the
692          whole sampler [default] or only to the sampler channels that are
693          connected to the respective MIDI input port the SysEx message arrived
694          on)
695        - bugfix: notes triggered at position 0 in the audio buffer were
696          sometimes wrongly killed in the same buffer, causing no sound to
697          be played
698        - added support for chromatic / drumkit mode Roland GS Sysex message
699          which is usally used to switch a part between chromatic sounds and
700          drumkit sounds (as opposed to their common default setting of MIDI
701          part 10 being a drumkit part and all other ones chromatic parts), in
702          LS however one can switch between the first 16 MIDI instrument maps
703          defined for the sampler
704        - made it possible to create multiple sample channels even if the
705          audio thread isn't running
706        - fixed crash when removing channel with active voices (#116)
707        - bugfix: on sample reference changes (instrument editor), only
708          un-cache the respective sample if it's really not used by any
709          sampler engine anymore
710        - re-cache samples in case they were changed by an instrument editor,
711          e.g. when a sample was added while playing (#82)
712        - fixed hanging notes which occured when note-off event had the exact
713          same time stamp as the voice's note-on event and occured both in the
714          same audio fragment cycle (fixes bug #112)
715        - added support for the "fine tune" and "pitch bend range"
716          instrument-level gig parameters
717        - fixed minor artifacts in pitch bend handling
718        - added support for GS Reset SysEx message
719        - allow gig files to use unlimited downward pitch shifting
720        - added a limit check for upward pitch shifting
721        - bugfix: sometimes, when playing a note twice fast, the second
722          note was silent
723        - fixed crash happening when a pitch bend event arrived at the
724          same time a new instrument was loading
726      * LSCP server:
727        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
728          react on MIDI data arriving on certain sampler channels (so far only
729          Note-On and Note-Off events are sent via this LSCP event)
730        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
731          react on MIDI data arriving on certain MIDI input devices (so far only
732          Note-On and Note-Off events are sent via this LSCP event)
733        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
735        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
736          frontends to send MIDI messages to specific sampler channel
737        - added two additional fields to GET FILE INSTRUMENT INFO command -
739        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
740          was incorrect
741        - Optimized the retrieval of the MIDI instrument mappings
742        - added new LSCP command "SET VOICES" to globally alter the maximum
743          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
744          be triggered respectively
745        - added new LSCP command "SET STREAMS" to globally alter the maximum
746          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
747          which will be triggered respectively
748        - bugfix: retry if "select" returns EINTR (this fixes a crash when
749          a gigedit file dialog is opened)
750        - close all connections when LSCPServer is deleted
751        - hard close of all sockets on exit
752        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
753          driver
755      * Bug fixes:
756        - fixed a crash which occurs when removing a sampler channel waiting
757          to start instrument loading after another channel
758        - fixed a crash which occurs when removing a sampler channel with
759          instrument loading in progress (bug #113)
760        - fixed termination caused by uncaught exception when adding MIDI
761          instrument with PERSISTENT load mode
762        - fixed possible iterator invalidations when resetting the sampler
763        - fixed memory leaks when issuing the following LSCP commands:
768        - fixed possible compilation error when sqlite is not present
769        - fixed orphaned pointers when setting maximum voices limit (bug #118)
770        - fixed crash when changing the audio output device of a sampler
771          channel with loaded instrument and start playing notes
772        - fixed endless loop in Engine::SuspendAll() (bug #120)
773        - fixed a low-level atomic load function that was broken on 64-bit
774          PowerPC, which probably could cause crashes on that platform
775        - fixed a memory management error which could cause a crash when a
776          plugin was unloaded
777        - bugfix: two private structs had the same name, which could cause
778          problems if the linker chose the wrong constructor
779        - fixed low-level ConditionServer usage bug that caused lockups on
780          Windows
783    Version 0.5.1 (6 December 2007)
785      * packaging changes:
786        - added autoconf checks for pthread library
787        - added autoconf check for pthread bug found on certain NPTL-enabled
788          glibc versions (see Gentoo bug report #194076)
789        - added autoconf checks for MS Windows
791      * general changes:
792        - bugfix: the thread used by an editor plugin didn't die when the
793          editor closed
794        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
795          out all the space. operator--() did not apply size_mask after
796          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
797          order to avoid problems with the _NonVolatileReader functions.
798        - bugfix: Stream.h: added a missing divide by BytesPerSample in
799          GetWriteSpace(). Since this function is currently only used in
800          the stream's qsort() compare function, it didn't trigger any
801          bugs.
802        - Resampler.h, Synthesizer.h: cubic interpolation now works in
803          24bit mode too. Faster method to read 24bit words on little
804          endian machines (x86): replaced 3 byte reads + shifts with a 1
805          unaligned 32bit read and shift
806        - experimental support for MS Windows (MIDI input via MME, AUDIO
807          output via ASIO)
808        - made handling of SIGINT signal (Ctrl-C) a bit more robust
809        - support for monitoring the total number of active disk streams
810          (new LSCP commands: GET TOTAL_STREAM_COUNT,
813      * AUDIO driver:
814        - added Windows ASIO low latency audio driver
816      * MIDI driver:
817        - added MME Windows MIDI driver
819      * LSCP server:
820        - added support for Windows style path / filenames, however with
821          forward slash path separators instead of backslash
822          (i.e. "C:/foo/bar.gig")
823        - allow naughty liblscp to send non-string device parameters within
824          apostrophes as well
825        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
826          "LIST FILE INSTRUMENTS <file>" and
827          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
828          about an arbitrary instrument file on the system where the sampler is
829          running on
831    Version 0.5.0 (15 October 2007)
833    * packaging changes:    * packaging changes:
834        - config.h is not going to be installed along with liblinuxsampler's
835          API header files anymore
836        - only the API relevant header (and source) files will be exported to
837          the Doxygen API documentation (explicitly listed in Doxyfile.in)
838        - added completely new XCode project files for Mac OSX which is now
839          capable to execute our autoconf environment, thus no need anymore
840          to maintain the compile time configuration file (osx/version.h) for
841          OSX manually (patch by Toshi Nagata)
842        - fixed buggy boolean --enable-foo / --disable-foo configure script
843          parameters
844        - global.h now only covers global definitions that are needed for the
845          C++ API header files, all implementation internal global definitions
846          are now in global_private.h
847        - atomic.h is not exposed to the C++ API anymore
848        - no need to include config.h anymore for using LS's API header files
849        - fixed warnings in API doc generation
851      * general changes:
852        - replaced the old, confusing MIDI program change mechanism by a
853          flexible MIDI instrument mapper which allows to map arbitrary
854          (MIDI bank, MIDI program) pairs with arbitrary
855          (engine type, instrument file, file index) triplets which will be
856          loaded on the respective channel when such MIDI program change
857          messages arrive, beside that, each entry allows to define a life-time
858          strategy for the instrument, so the user can define whether the
859          instrument should i.e. be permanently loaded (to be able to switch
860          quickly among sounds) or i.e. loaded just on demand when the
861          respective program change arrives (to safe RAM space), as well as a
862          global volume factor for each entry, so the user can adjust the volume
863          dynamic of his mapped instrument collection without having to modify
864          the instrument files, also one can manage arbitrary amount of such
865          MIDI instrument maps and assign each sampler channel individually
866          a certain map, so that i.e. separation of normal instruments and
867          drumkits is possible
868        - new notification events for tracking changes to audio/MIDI devices,
869          MIDI instrument maps, MIDI instruments, FX sends, global volume.
870        - sampler was limited to load max. 200 instruments in the background
871          due to a constant size RingBuffer FIFO which is now replaced by a
872          dynamic (unlimited) size std::list FIFO
873        - added FX sends, these allow to route audio signals to arbitrary audio
874          output channels for being processed by external effect processors
875          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
876          controllers
877        - global (sampler wide) volume can now be controlled at runtime
878        - Implemented new, improved notification system
879        - fixed compilation errors regarding OSX
880          (patch by Toshi Nagata)
881        - implemented instruments database
882        - added support for escape sequences to the instruments database
883        - added highly experimental support for on-the-fly instrument editing
884          within the sampler's process (by using instrument editor plugins),
885          you'll notice the new "Registered instrument editors:" message on
886          startup, added a new LSCP command:
887          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
888          to spawn a matching instrument editor for the instrument on the
889          given sampler channel, the plugin path can be overridden at compile
890          time with ./configure --enable-plugin-dir=/some/dir
891        - added experimental code for synchronizing instrument editors hosted
892          in the sampler's process to safely edit instruments while playing
893          without a crash (hopefully) by either suspending single regions
894          wherever possible or if unavoidable whole engine(s)
895        - fixed several issues in fundamental "Thread" class: set scheduling
896          policy and priority on thread level, set a minimum stack size for
897          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
898          threads simply inherited properties of starting thread instead of
899          setting their own policy and priority
900        - minor fix in our automatic stack trace mechanism on crashes, the
901          main process did not wait for the stack trace process to finish
902          its output
903        - fixed some minor memory leaks
904        - reenabled assembly features support, at the moment only for
905          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
906        - minor assembly fix in x86 features detection (don't use the PIC
907          register, to avoid relocations in the text segment at runtime)
908        - POSIX callback functions of Thread.h are hidden
910      * MIDI driver:
911        - dispatch bank select (MSB and LSB) messages
913      * audio driver:
914        - the ALSA audio output driver parameters now reflect the correct
915          parameter value ranges for the respective selected sound card
916          (patch by Till Wimmer, a bit fixed and extended)
918      * Gigasampler format engine:
919        - if a filter is used and EG2 finishes before EG1, let the voice
920          die when EG2 has finished (this fixes a problem with clicks and
921          voice starvation for some gigs)
922        - playback is no longer disabled during instrument loading
923        - all notes playing on a channel that changes its instrument keep
924          playing with the old instrument until they get a note off
925          command
926        - EG fix: a release value of zero could cause noises or crash
927        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
928        - EG fine tuning: when attack is zero the EG starts at a level
929          above max sustain level, which means that there is a decay phase
930          even if sustain is 100%
931        - more EG fixes: the level could sometimes go below zero and cause
932          noises or crashes
933        - minor fix of EGDecay (patch by Toshi Nagata)
934        - fixed compiler error when --enable-override-filter-type was
935          supplied to the configure script (fixes #46)
936        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
937          instead of a fix value
938        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
939          127 (solo mode) only kill voices if the respective mode really
940          changed
942      * LSCP server:
943        - fixed compile time error for old Bison versions
944          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
945        - parser now supports extended ASCII character set
946          (up to ASCII code 255, i.e. includes now umlauts and accents)
947        - filename arguments in LSCP commands now allow to use escape
948          sequences, that is directly literal as one of: \', \", \\, \n, \r,
949          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
950          code value like \xf2) (fixes bug #24)
951        - the following LSCP commands now also support escape sequences for at
952          least one of their text-based parameters (i.e. name, description):
959        - returns verbose syntax errors (line and column where syntax error
960          occured, the unexpected character and the actually expected, possible
961          character(s), the latter only if less than 5 possibilities)
962        - made sure that LSCP syntax is not affected by gigedit locale
963          settings
964        - bugfix regarding strings parameter lists: all comma separated lists
965          of strings were treated as being one string containing commas
966          (fixes #57)
968      * Bug fixes:
969        - fixed crash occurring on certain LSCP scripts (Bug 39)
970        - another thread safety fix for lscp "load engine" and "set
971          channel audio output device"
972        - fixed a crash which occurs when reassigning the same engine
973          on a sampler channel with connected MIDI device
974        - fixed a crash which occurs when changing the number of ports of a MIDI
975          device connected to a sampler channel to number less then or equal
976          to the index of the port to which the sampler channel is connected.
977        - The previous bindings were not been disconnected when altering
978          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
979          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
980        - The active stream/voice count statistic was incorrect.
981        - notification events were not been sent for some sampler
982          channel changes
983        - added default min and max values to restrict the number of allowed
984          audio output channels and MIDI input ports
985        - the connection to the PCM interface is now closed when destroying
986          an audio output device
987        - files with slash in their path or filename could not be loaded
989      * test cases:
990        - updated and fixed (haven't been touched in a while)
992    Version 0.4.0 (24 November 2006)
994      * packaging changes:
995        - changed deprecated copyright attribute to license; added ldconfig
996          to post-(un)install steps; added devel package for liblinuxsampler;
997          to linuxsampler.spec (RPM)

1033          which can be overridden with --enable-global-attenuation
1034        - EG fixes: made the length of "attack hold" stage more
1035          accurate. Release stage can now start before attack stage
1036          ends. Cancel release didn't work when sustain was zero. Attack
1037          time now has a minimal value to prevent clicks.
1038        - fixed pitch changes larger than one octave
1039        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1040        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1041          all modes can be altered via standard GM messages, that is CC5 for
1042          altering portamento time, CC65 for enabling / disabling portamento
1043          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1044        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1045          parameter) and crossfade
1046        - added support for the "attenuation controller threshold" gig
1047          parameter
1048        - added smoothing of volume changes caused by control change
1049          messages
1050        - sample loop parameters are now taken from the DimensionRegion
1051          instead of the wave chunk
1052        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1053          not equal to a power of two
1054        - reimplementation of the filter algorithm. The new filter is more
1055          accurate and supports all gig filter types, including bandreject
1056          and lowpass turbo.
1057        - real support for 24 bit samples - samples are not truncated to
1058          16 bits anymore
1059        - support for aftertouch (channel pressure, not polyphonic
1060          aftertouch)
1061        - LFO1 behaviour fixed (dampening from max volume instead of
1062          amplifying from 0)
