31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37        - enabled automake 'subdir-objects' option and moved external
38          source references (vst, au, asio) from makefiles to cpp files,
39          in order to get rid of warnings from automake 1.14
40    
41      * general changes:
42        - Refactoring: moved the independent code from
43          the Gigasampler format engine to base classes
44        - command line option '--profile' is currently disabled, since the
45          respective profiling code is currently broken
46        - Introduced support for optional environment variable
47          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48          where the sampler shall look for instrument editor plugins
49          (patch by Luis Garrido, slightly modified).
50        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53          note (in this implementation of the sampler its simply hard routed to
54          the 1st effect send of the sampler channel, no matter what the actual
55          effect type is)
56        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57          note (in this implementation of the sampler its simply hard routed to
58          the 2nd effect send of the sampler channel, no matter what the actual
59          effect type is)
60        - implemented support for internal LADSPA effects
61        - raised limit of program change queue from 100 to 512
62          (as suggested by Alex Stone)
63        - implemented sine LFO, pulse LFO and saw LFO
64        - experimental support for per voice equalization
65        - added command line option --exec-after-init
66        - Introduced new C++ API method:
67          EngineChannel::InstrumentFileName(int index)
68          allowing to retrieve the whole list of files used for the loaded
69          instrument on an engine channel (a.k.a. part). Some GigaStudio
70          instruments for example are splitted over several files like
71          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72        - Added new C++ API method Sampler::GetGlobalMaxVoices().
73        - Added new C++ API method Sampler::GetGlobalMaxStreams().
74        - Added new C++ API method Sampler::SetGlobalMaxVoices().
75        - Added new C++ API method Sampler::SetGlobalMaxStreams().
76        - Various "const" and "restrict" optimizations.
77        - all engines: add pan CC value to instrument pan parameter before
78          applying panning, instead of using two separate pan functions in
79          series (#182)
80        - added a lock guard class for exception safe mutex handling and
81          used it everywhere appropriate
82        - Immediately apply scale tuning changes to active voices.
83        - Exposed scale tuning to C++ API (along to the already existing standard
84          SysEx way).
85        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86          and broken for ppc64. (Seq_cst loads and stores are actually not
87          used in LS, so the bug wasn't noticable.)
88        - lsatomic.h: added ARMv7 support
89        - Added support for multiple MIDI input ports per sampler channel (and
90          added various new C++ methods for this new feature / design change, old
91          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92          as deprecated but are still there and should provide full behavior
93          backward compatibility).
94        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95          unsafe and caused compilation error with clang 2.x).
96        - Bugfix: only process the latest MIDI program change event.
97        - Introducing the LSCP shell, which provides convenient control of the
98          sampler from the command line by providing LSCP aware features.
99        - VirtualMidiDevice: Added support for program change.
100        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101        - VirtualMidiDevice: Added support for pitch bend.
102        - Aftertouch: extended API to explicitly handle channel pressure and
103          polyphonic key pressure events (so far polyphonic pressure was not
104          supported at all, and channel pressure was rerouted as CC128 but not
105          used so far).
106    
107      * Gigasampler format engine:
108        - implemented the "round robin keyboard" dimension
109        - fixed round robin and random dimensions for cases when number of
110          dimension zones is not a power of two
111        - made round robin use a counter for each region instead of each
112          key
113        - bugfix: pitch LFO controller "internal+aftertouch" was broken
114        - bugfix: filter keyboard tracking was broken
115        - filter performance fix (an unnecessary copy was made of the
116          filter parameters in each sub fragment)
117        - handle special case when pan parameter in gig file has max or
118          min value
119        - Exclusive Groups: don't ever stop voices of the same note,
120          doesn't sound naturally with a drumkit
121        - fixed EG1 modulation when attack or release is zero
122        - Fixed support for 'aftertouch' attenuation controller.
123

130        - added support for trigger=first, trigger=legato and sw_previous
131        - allow non-numerical key values ("C#4" for example)
132        - "key" opcode now sets pitch_keycenter too
133        - fixed error when unloading instrument with same sample used by
134          multiple regions
135        - added some opcode aliases, like loopmode for loop_mode, to be
136          more compatible

285          after each "#include", only after the main file is parsed
286        - bugfix: line numbers in error messages were wrong after "#include"
287    
288      * SoundFont format engine:

298        - AU bugfix: failed to destroy its audio/MIDI devices
299        - Listen to all interfaces on Mac OS X (INADDR_ANY)
300        - VST bugfix: If the host called resume() before and after
301          changing sample rate or block size, the number of channels was
302          incorrectly set to two. This caused silence in Cubase 5.
303        - save engine type (gig, sfz or sf2) in plugin state
304        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
305          64 bit Windows
306        - AU: changed number of output channels from one stereo to 16
307          stereo

313          the plugin was loaded a second time (#174)
314        - plugin bugfix: instrument loading hang when the plugin was
315          loaded a second time (this time it's for Linux and Mac, previous
316          similar fix was for Windows)
317        - thread safety fixes for the instrument loading thread
318        - LV2: use the new lv2 package if present
319        - VST: try to open Fantasia automatically on Linux and Mac too (on
320          Linux, the Fantasia jar should be placed in <prefix>/share/java)
321        - VST: fixed crashes on Linux Ardour and EnergyXT
322        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
323          port and audio channel routing for DSSI plugins are now visible.
324        - LV2: use urid and atom extensions instead of deprecated uri-map
325          and event
326        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
327        - LV2: changed number of output channels to 16 stereo, just like
328          the VST and AU plugins
329        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
330        - LV2: made LV2 plugin buildable on Windows and Mac
331        - VST: implemented retrieval and switching of programs using the
332          sampler's internal MIDI instrument mapping system
333    
334      * MIDI driver:
335        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
336          the ALSA sequencer client name
337        - removed limit of maximum amount of MIDI ports per MIDI device, since
338          there is no reason for this limit
339        - MME: fixed memory handling bug found with cppcheck
340        - MME: removed compiler warning
341        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
342          which allows to retrieve the list of CoreMIDI clients / ports and to connect
343          to them a la JACK, via the usual sampler APIs
344        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
345          the driver will automatically connect to other CoreMIDI clients' ports
346          (e.g. external MIDI devices being attached to the Mac)
347        - added support for MIDI note on velocity filter
348        - CoreMIDI: fixed memory deallocation error
349        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
350          virtual keyboards in frontends / instrument editors being stuck.
351        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
352        - Implemented missing handling of MIDI "running status".
353        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
354        - MME bugfix: driver wasn't closed properly
355    
356      * audio driver:

366          for audio device parameter "SAMPLERATE" (fixes #166).
367    
368      * LSCP server:
369        - added support for sending MIDI CC messages via LSCP command

404        - provide comprehensive error messages on LSCP syntax errors
405          (suggesting expected next non-terminal symbols)
406    
407      * LSCP shell:
408        - Added support for auto correction of obvious and trivial syntax mistakes.
409        - Added support for auto completion by tab key.
410        - Show currently available auto completion while typing.
411        - Added support for browsing command history with up / down keys.
412        - Show all possible next symbols immediately right to the current command
413          line while typing (no double tab required for this feature, as it would
414          be the case in other shells).
415        - Added support for moving cursor left/right with arrow keys.
416        - Added support for built-in LSCP reference documentation, which will
417          automatically show the relevant LSCP reference section on screen as soon
418          as one specific LSCP command was detected while typing on the command
419          line.
420    
421      * Bug fixes:
422        - Fixed crash which may occur when MIDI key + transpose is out of range
423        - minor valgrind fixes
424        - fixed crash which occurred when changing an already deployed sampler
425          channel to a different engine type
426        - fixed crash when deleting a sampler channel or changing engine
427          type while an instrument load was in progress
428        - bugfix: playing a note while changing the instrument could cause
429          a crash, or give "Handing back unknown region" error messages
430        - bugfix: calling SET VOICES (which Fantasia does on start and
431          refresh) could cause instruments to be unloaded
432        - Mac OS X: fixed name collision of enum in EffectControl and
433          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
434        - Mac OS X: fixed hanging threads
435        - Windows: disabled the previous thread fix on non-Mac systems, as
436          it caused hanging threads on Windows
437        - Fixed possible crashes due to corrupted MIDI/audio device list
438          after MIDI/audio device creation failure
439        - When creating MIDI instrument map entries with "PERSISTENT" type, the
440          instruments were uselessly precached with zero samples, however it still
441          took the full preloading time and on 1st program change the respective
442          instrument was completely reloaded again.
443        - fixed handling of rapid bank select and program change messages
444          sent to the same sampler channel (patch from the Open Octave
445          project, slightly adjusted)
446        - fixed crash when trying to create an effect instance with controls
447          which min and/or max values depend on the sample rate
448        - fixed bug #162
449        - bugfix: LADSPA_PATH was not evaluated correctly when containing
450          multiple paths (#165)
451        - thread safety fixes for the instrument loading thread
452        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
453          (#176)
454        - more thread safety fixes for the instrument loading thread
455        - sfz/sf2 engine: fixed crash when using small audio fragment size
456        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
457        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
458          introduced in previous fix)
459        - fixed crash when a channel received a program change while
460          playing a note in a key group
461        - fixed erroneous error message piping in VoiceBase.h
462          (labelled "Disk stream not available in time")
463        - Update effects on sample rate & period size changes (to avoid
464          crashes and noise on such transitions).
465        - ignore missing LADSPA paths without ignoring valid LADSPA paths
466          (fixes #208)
467        - Fixed bug in LSCP grammar definition which caused a statement like
468          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
469          practically irrelevant, however it caused problems with the new LSCP
470          shell's auto completion feature).
471    
472    Version 1.0.0 (31 July 2009)
473    
474      * packaging changes:
475        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
476          causing e.g. the libgig test to fail when
477          "./configure --disable-jack-driver" was used
478          (patch by Alexis Ballier)
479        - fixed compilation with gcc 4.3
480        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
481        - fixed configure so it detects x86_64 (#107)
482        - fixes for building with newer MinGW versions
483        - fix for building with bison 2.4 (#111)
484        - fixed building with libgig installed in a non-standard directory
485        - minor fix in configure for mmsystem.h detection on MinGW
486        - Windows: look for editor plugins and Fantasia using base
487          directory of liblinuxsampler dll (look in the same directory and one
488          directory above)
489        - configure script fix: removed unconditional use of SSE
490        - fixed building with sqlite installed in a non-standard directory
491        - when cross-compiling, don't try to create instruments.db
492        - fix for new mingw-w64 version, which has usleep
493    
494      * general changes:
495        - bugfix: on some POSIX systems instrument editor plugins refused to
496          load as we used a non-portable Linux specific struct field
497          (fixes bug #70, patch by Ronald Baljeu)
498        - fixed endless loop which occured when loading an instrument editor
499          plugin DLL on Windows systems failed
500        - fixed memory leaks that occurred when liblinuxsampler was unloaded
501        - optimized the SynchronizedConfig class so it doesn't wait
502          unnecessarily long after an update
503        - added support for notifying instrument editors on note-on / note-off
504          events (e.g. to highlight the pressed keys on the virtual keyboard
505          of gigedit)
506        - added support for triggering notes by instrument editors (see above)
507        - be verbose on DLL load errors (on Linux)
508        - fixed di-harmonic triangle LFO implementation (this LFO implementation
509          is only used by very few systems, most pick the int math
510          implementation, which is usually faster)
511        - fixes for audio drivers with varying buffer sizes
512        - experimental support for running LinuxSampler as a DSSI, LV2 and
513          VST plugin
514        - notification events for stream/voice count statistics are now sent
515          only when there are actual changes
516        - added memory ordering constraints to improve stability on
517          multi-core and multi-cpu systems
518        - maximum voices and disk streams can now be altered at runtime
519        - fixed CPU feature detection on x86_64 (maybe fixes #108)
520        - automatic stacktrace mechanism is now turned off by default and can
521          be switched on by command line option "--stacktrace" (the automatic
522          stacktrace mechanism seems to be broken on most systems at the moment)
523        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
524          a pointer to the launched InstrumentEditor object
525        - added optional 3rd party user data parameter for following
526          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
527          InstrumentEditor::Launch(),
528          InstrumentManager::LaunchInstrumentEditor()
529        - theoretical fix: made SynchronizedConfig follow C++0x memory
530          model more strictly
531        - fixes for using large audio device buffers
532        - Windows: add the installation directory to the DLL search path
533          when loading an editor plugin (solves problems with VST and
534          gigedit on systems with other GTK versions installed)
535        - updated linuxsampler man page
536    
537      * audio driver:
538        - removed the nonsense audio channel constraint (which was hard coded to
539          max. 100 audio channels) for most audio drivers
540        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
541          opposed to the LSCP specs
542        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
543          reflected the wrong value
544        - fixed a memory management bug in ASIO driver
545        - Makefile fix: JACK_CFLAGS wasn't used
546        - JACK: use jack_client_open instead of the deprecated
547          jack_client_new
548        - added (experimental) CoreAudio driver
549        - applied old fixes to the ASIO driver that were included in the
550          previous binary release but accidentally never committed to CVS
551          (fixes #117)
552        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
553          win64)
554        - VST: added support for sample rate and buffer size changes
555        - VST: close editor (Fantasia) when the VST is removed
556        - VST: avoid opening Fantasia more than once for each VST instance
557        - VST: export main function as "main" on Linux too (fix for
558          energyXT)
559        - VST: changed number of output channels from one stereo to 16
560          stereo
561        - added channel routing, fxsends and midi maps to the settings
562          stored in the plugin state
563        - performance optimization of AudioChannel::MixTo() and
564          AudioChannel::CopyTo() methods using GCC vector exensions
565          (if available)
566        - ASIO fixes: avoid initializing the device twice, avoid throwing
567          exception when getting parameters from a disconnected device
568    
569      * MIDI driver:
570        - added JACK MIDI driver
571        - dispatch bank select as ordinary CC as well, the user might seriously
572          want to (mis)use it for some purpose ("fixed" in all current MIDI
573          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
574        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
575          CoreMidi or AU
576        - fixed mingw-w64 compilation error in MME driver
577        - made program change handling in MIDI thread real-time safe by
578          moving the logic to a non-RT thread
579        - fixed minor memory leak in ALSA driver
580    
581      * instruments database:
582        - avoid time consuming samples scanning when adding instruments
583          to the instruments database
584        - added support for handling lost files in the instruments database
585        - Implemented option for adding instruments in separate directories
586          in the instruments database
587          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
588        - work-around for missing fnmatch function on Windows to make
589          instrument database compilable
590        - added instrument database support on Windows
591          works with both standalone mode and VST plugin.
592          the instruments DB file is located in
593          %USERPROFILE%\.linuxsampler\instruments.db which allows different
594          databases for each windows user
595          if no DB is present it automatically creates the .linuxsampler subdir
596          and then creates an empty DB
597        - fixed recursive import, which was broken on Windows
598    
599      * Gigasampler format engine:
600        - fixed a memory leak that could happen when a channel was deleted
601          while notes were playing
602        - made it possible to load an instrument even if the audio thread
603          isn't running
604        - added partial support for the "Controller Triggered" MIDI rule,
605          enough for piano gigs with pedal noise samples
606        - minor fix: only mark FX sends as being modified if really the
607          respective FX send MIDI controller was used
608        - added support for GM global device volume SysEx message
609          (can be selected at compile time to either apply globally to the
610          whole sampler [default] or only to the sampler channels that are
611          connected to the respective MIDI input port the SysEx message arrived
612          on)
613        - bugfix: notes triggered at position 0 in the audio buffer were
614          sometimes wrongly killed in the same buffer, causing no sound to
615          be played
616        - added support for chromatic / drumkit mode Roland GS Sysex message
617          which is usally used to switch a part between chromatic sounds and
618          drumkit sounds (as opposed to their common default setting of MIDI
619          part 10 being a drumkit part and all other ones chromatic parts), in
620          LS however one can switch between the first 16 MIDI instrument maps
621          defined for the sampler
622        - made it possible to create multiple sample channels even if the
623          audio thread isn't running
624        - fixed crash when removing channel with active voices (#116)
625        - bugfix: on sample reference changes (instrument editor), only
626          un-cache the respective sample if it's really not used by any
627          sampler engine anymore
628        - re-cache samples in case they were changed by an instrument editor,
629          e.g. when a sample was added while playing (#82)
630        - fixed hanging notes which occured when note-off event had the exact
631          same time stamp as the voice's note-on event and occured both in the
632          same audio fragment cycle (fixes bug #112)
633        - added support for the "fine tune" and "pitch bend range"
634          instrument-level gig parameters
635        - fixed minor artifacts in pitch bend handling
636        - added support for GS Reset SysEx message
637        - allow gig files to use unlimited downward pitch shifting
638        - added a limit check for upward pitch shifting
639        - bugfix: sometimes, when playing a note twice fast, the second
640          note was silent
641        - fixed crash happening when a pitch bend event arrived at the
642          same time a new instrument was loading
643    
644      * LSCP server:
645        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
646          react on MIDI data arriving on certain sampler channels (so far only
647          Note-On and Note-Off events are sent via this LSCP event)
648        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
649          react on MIDI data arriving on certain MIDI input devices (so far only
650          Note-On and Note-Off events are sent via this LSCP event)
651        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
652          SET DB_INSTRUMENT FILE_PATH
653        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
654          frontends to send MIDI messages to specific sampler channel
655        - added two additional fields to GET FILE INSTRUMENT INFO command -
656          KEY_BINDINGS and KEYSWITCH_BINDINGS
657        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
658          was incorrect
659        - Optimized the retrieval of the MIDI instrument mappings
660        - added new LSCP command "SET VOICES" to globally alter the maximum
661          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
662          be triggered respectively
663        - added new LSCP command "SET STREAMS" to globally alter the maximum
664          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
665          which will be triggered respectively
666        - bugfix: retry if "select" returns EINTR (this fixes a crash when
667          a gigedit file dialog is opened)
668        - close all connections when LSCPServer is deleted
669        - hard close of all sockets on exit
670        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
671          driver
672    
673      * Bug fixes:
674        - fixed a crash which occurs when removing a sampler channel waiting
675          to start instrument loading after another channel
676        - fixed a crash which occurs when removing a sampler channel with
677          instrument loading in progress (bug #113)
678        - fixed termination caused by uncaught exception when adding MIDI
679          instrument with PERSISTENT load mode
680        - fixed possible iterator invalidations when resetting the sampler
681        - fixed memory leaks when issuing the following LSCP commands:
682          GET AUDIO_OUTPUT_DRIVER INFO
683          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
684          GET MIDI_INPUT_DRIVER INFO
685          GET MIDI_INPUT_DRIVER_PARAMETER INFO
686        - fixed possible compilation error when sqlite is not present
687        - fixed orphaned pointers when setting maximum voices limit (bug #118)
688        - fixed crash when changing the audio output device of a sampler
689          channel with loaded instrument and start playing notes
690        - fixed endless loop in Engine::SuspendAll() (bug #120)
691        - fixed a low-level atomic load function that was broken on 64-bit
692          PowerPC, which probably could cause crashes on that platform
693        - fixed a memory management error which could cause a crash when a
694          plugin was unloaded
695        - bugfix: two private structs had the same name, which could cause
696          problems if the linker chose the wrong constructor
697        - fixed low-level ConditionServer usage bug that caused lockups on
698          Windows
699    
700    
701    Version 0.5.1 (6 December 2007)
702    
703      * packaging changes:
704        - added autoconf checks for pthread library
705        - added autoconf check for pthread bug found on certain NPTL-enabled
706          glibc versions (see Gentoo bug report #194076)
707        - added autoconf checks for MS Windows
708    
709      * general changes:
710        - bugfix: the thread used by an editor plugin didn't die when the
711          editor closed
712        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
713          out all the space. operator--() did not apply size_mask after
714          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
715          order to avoid problems with the _NonVolatileReader functions.
716        - bugfix: Stream.h: added a missing divide by BytesPerSample in
717          GetWriteSpace(). Since this function is currently only used in
718          the stream's qsort() compare function, it didn't trigger any
719          bugs.
720        - Resampler.h, Synthesizer.h: cubic interpolation now works in
721          24bit mode too. Faster method to read 24bit words on little
722          endian machines (x86): replaced 3 byte reads + shifts with a 1
723          unaligned 32bit read and shift
724        - experimental support for MS Windows (MIDI input via MME, AUDIO
725          output via ASIO)
726        - made handling of SIGINT signal (Ctrl-C) a bit more robust
727        - support for monitoring the total number of active disk streams
728          (new LSCP commands: GET TOTAL_STREAM_COUNT,
729          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
730    
731      * AUDIO driver:
732        - added Windows ASIO low latency audio driver
733    
734      * MIDI driver:
735        - added MME Windows MIDI driver
736    
737      * LSCP server:
738        - added support for Windows style path / filenames, however with
739          forward slash path separators instead of backslash
740          (i.e. "C:/foo/bar.gig")
741        - allow naughty liblscp to send non-string device parameters within
742          apostrophes as well
743        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
744          "LIST FILE INSTRUMENTS <file>" and
745          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
746          about an arbitrary instrument file on the system where the sampler is
747          running on
748    
749    Version 0.5.0 (15 October 2007)
750    
751      * packaging changes:
752        - config.h is not going to be installed along with liblinuxsampler's
753          API header files anymore
754        - only the API relevant header (and source) files will be exported to
755          the Doxygen API documentation (explicitly listed in Doxyfile.in)
756        - added completely new XCode project files for Mac OSX which is now
757          capable to execute our autoconf environment, thus no need anymore
758          to maintain the compile time configuration file (osx/version.h) for
759          OSX manually (patch by Toshi Nagata)
760        - fixed buggy boolean --enable-foo / --disable-foo configure script
761          parameters
762        - global.h now only covers global definitions that are needed for the
763          C++ API header files, all implementation internal global definitions
764          are now in global_private.h
765        - atomic.h is not exposed to the C++ API anymore
766        - no need to include config.h anymore for using LS's API header files
767        - fixed warnings in API doc generation
768    
769      * general changes:
770        - replaced the old, confusing MIDI program change mechanism by a
771          flexible MIDI instrument mapper which allows to map arbitrary
772          (MIDI bank, MIDI program) pairs with arbitrary
773          (engine type, instrument file, file index) triplets which will be
774          loaded on the respective channel when such MIDI program change
775          messages arrive, beside that, each entry allows to define a life-time
776          strategy for the instrument, so the user can define whether the
777          instrument should i.e. be permanently loaded (to be able to switch
778          quickly among sounds) or i.e. loaded just on demand when the
779          respective program change arrives (to safe RAM space), as well as a
780          global volume factor for each entry, so the user can adjust the volume
781          dynamic of his mapped instrument collection without having to modify
782          the instrument files, also one can manage arbitrary amount of such
783          MIDI instrument maps and assign each sampler channel individually
784          a certain map, so that i.e. separation of normal instruments and
785          drumkits is possible
786        - new notification events for tracking changes to audio/MIDI devices,
787          MIDI instrument maps, MIDI instruments, FX sends, global volume.
788        - sampler was limited to load max. 200 instruments in the background
789          due to a constant size RingBuffer FIFO which is now replaced by a
790          dynamic (unlimited) size std::list FIFO
791        - added FX sends, these allow to route audio signals to arbitrary audio
792          output channels for being processed by external effect processors
793          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
794          controllers
795        - global (sampler wide) volume can now be controlled at runtime
796        - Implemented new, improved notification system
797        - fixed compilation errors regarding OSX
798          (patch by Toshi Nagata)
799        - implemented instruments database
800        - added support for escape sequences to the instruments database
801        - added highly experimental support for on-the-fly instrument editing
802          within the sampler's process (by using instrument editor plugins),
803          you'll notice the new "Registered instrument editors:" message on
804          startup, added a new LSCP command:
805          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
806          to spawn a matching instrument editor for the instrument on the
807          given sampler channel, the plugin path can be overridden at compile
808          time with ./configure --enable-plugin-dir=/some/dir
809        - added experimental code for synchronizing instrument editors hosted
810          in the sampler's process to safely edit instruments while playing
811          without a crash (hopefully) by either suspending single regions
812          wherever possible or if unavoidable whole engine(s)
813        - fixed several issues in fundamental "Thread" class: set scheduling
814          policy and priority on thread level, set a minimum stack size for
815          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
816          threads simply inherited properties of starting thread instead of
817          setting their own policy and priority
818        - minor fix in our automatic stack trace mechanism on crashes, the
819          main process did not wait for the stack trace process to finish
820          its output
821        - fixed some minor memory leaks
822        - reenabled assembly features support, at the moment only for
823          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
824        - minor assembly fix in x86 features detection (don't use the PIC
825          register, to avoid relocations in the text segment at runtime)
826        - POSIX callback functions of Thread.h are hidden
827    
828      * MIDI driver:
829        - dispatch bank select (MSB and LSB) messages
830    
831      * audio driver:
832        - the ALSA audio output driver parameters now reflect the correct
833          parameter value ranges for the respective selected sound card
834          (patch by Till Wimmer, a bit fixed and extended)
835    
836      * Gigasampler format engine:
837        - if a filter is used and EG2 finishes before EG1, let the voice
838          die when EG2 has finished (this fixes a problem with clicks and
839          voice starvation for some gigs)
840        - playback is no longer disabled during instrument loading
841        - all notes playing on a channel that changes its instrument keep
842          playing with the old instrument until they get a note off
843          command
844        - EG fix: a release value of zero could cause noises or crash
845        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
846        - EG fine tuning: when attack is zero the EG starts at a level
847          above max sustain level, which means that there is a decay phase
848          even if sustain is 100%
849        - more EG fixes: the level could sometimes go below zero and cause
850          noises or crashes
851        - minor fix of EGDecay (patch by Toshi Nagata)
852        - fixed compiler error when --enable-override-filter-type was
853          supplied to the configure script (fixes #46)
854        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
855          instead of a fix value
856        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
857          127 (solo mode) only kill voices if the respective mode really
858          changed
859    
860      * LSCP server:
861        - fixed compile time error for old Bison versions
862          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
863        - parser now supports extended ASCII character set
864          (up to ASCII code 255, i.e. includes now umlauts and accents)
865        - filename arguments in LSCP commands now allow to use escape
866          sequences, that is directly literal as one of: \', \", \\, \n, \r,
867          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
868          code value like \xf2) (fixes bug #24)
869        - the following LSCP commands now also support escape sequences for at
870          least one of their text-based parameters (i.e. name, description):
871          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
872          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
873          "SET DB_INSTRUMENT_DIRECTORY NAME",
874          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
875          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
876          "FIND DB_INSTRUMENT_DIRECTORIES"
877        - returns verbose syntax errors (line and column where syntax error
878          occured, the unexpected character and the actually expected, possible
879          character(s), the latter only if less than 5 possibilities)
880        - made sure that LSCP syntax is not affected by gigedit locale
881          settings
882        - bugfix regarding strings parameter lists: all comma separated lists
883          of strings were treated as being one string containing commas
884          (fixes #57)
885    
886      * Bug fixes:
887        - fixed crash occurring on certain LSCP scripts (Bug 39)
888        - another thread safety fix for lscp "load engine" and "set
889          channel audio output device"
890        - fixed a crash which occurs when reassigning the same engine
891          on a sampler channel with connected MIDI device
892        - fixed a crash which occurs when changing the number of ports of a MIDI
893          device connected to a sampler channel to number less then or equal
894          to the index of the port to which the sampler channel is connected.
895        - The previous bindings were not been disconnected when altering
896          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
897          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
898        - The active stream/voice count statistic was incorrect.
899        - notification events were not been sent for some sampler
900          channel changes
901        - added default min and max values to restrict the number of allowed
902          audio output channels and MIDI input ports
903        - the connection to the PCM interface is now closed when destroying
904          an audio output device
905        - files with slash in their path or filename could not be loaded
906    
907      * test cases:
908        - updated and fixed (haven't been touched in a while)
909    
910    Version 0.4.0 (24 November 2006)
911    
912      * packaging changes:
913        - changed deprecated copyright attribute to license; added ldconfig
914          to post-(un)install steps; added devel package for liblinuxsampler;
915          to linuxsampler.spec (RPM)
916      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party
917        applications to link against liblinuxsampler        applications to link against liblinuxsampler
918      - liblinuxsampler's API documentation can be generated with 'make docs'      - liblinuxsampler's API documentation can be generated with 'make docs'
919        (Doxygen required)        (Doxygen required)
920        - added benchmark to automatically detect the best triangle LFO
921          implementation (currently either an integer math solution or a
922          di-harmonic approximation), automatic detection can be overriden
923          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
924          configure script argument though (mandatory for cross-compilation)
925        - do not automatically pick optimized gcc flags if the user already
926          provided some on his own (as CXXFLAGS)
927        - added compile time option to disable processing of All-Notes-Off MIDI
928          messages
929        - added compile time options to allow disabling the various audio and
930          MIDI drivers
931        - fixed automatic GCC CPU switch detection on PPC
932          (patch by Ebrahim Mayat)
933    
934    * Gigasampler format engine:    * Gigasampler format engine:
935        - extensive synthesis optimization
936          (reimplementation of EGs and LFO(s), removed synthesis parameter
937          prerendering and the synthesis parameter matrix in general, splitting
938          each audio fragment into subfragments now where each subfragment uses
939          constant pitch and filter coefficients. The volume coefficient is
940          linearly interpolated inside a subfragment, unless
941          --disable-interpolate-volume is set.)
942      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
943        - improved filter cutoff calculation by adding support for the
944          following gig parameters: Cutoff freq (used when no cutoff
945          controller is defined), Control invert, Minimum cutoff, Velocity
946          curve and Velocity range. The keyboard tracking now scales
947          cutoff frequency instead of resonance.
948        - added support for gig parameter Resonance.
949        - fixed bug in sysex handling (patch by Juan Linietsky)
950        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
951          which can be overridden with --enable-global-attenuation
952        - EG fixes: made the length of "attack hold" stage more
953          accurate. Release stage can now start before attack stage
954          ends. Cancel release didn't work when sustain was zero. Attack
955          time now has a minimal value to prevent clicks.
956        - fixed pitch changes larger than one octave
957        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
958        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
959          all modes can be altered via standard GM messages, that is CC5 for
960          altering portamento time, CC65 for enabling / disabling portamento
961          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
962        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
963          parameter) and crossfade
964        - added support for the "attenuation controller threshold" gig
965          parameter
966        - added smoothing of volume changes caused by control change
967          messages
968        - sample loop parameters are now taken from the DimensionRegion
969          instead of the wave chunk
970        - fixed keyswitching for v3 gigs with a number of keyswitch splits
971          not equal to a power of two
972        - reimplementation of the filter algorithm. The new filter is more
973          accurate and supports all gig filter types, including bandreject
974          and lowpass turbo.
975        - real support for 24 bit samples - samples are not truncated to
976          16 bits anymore
977        - support for aftertouch (channel pressure, not polyphonic
978          aftertouch)
979        - LFO1 behaviour fixed (dampening from max volume instead of
980          amplifying from 0)
981    
982    * LSCP server:    * LSCP server:
983      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
984        - fixed the notification messages delay due to lack of
985          network activity (fixes bug #26)
986        - fixed parser bug which occured on space(s) within device parameters
987          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
988    
989      * audio driver:
990        - added aRts audio output driver (by no means RT safe)
991    
992      * MIDI driver:
993        - fixed legacy sysex code which caused dispatching of MIDI SysEx
994          messages several times instead of once
995        - API extension for MIDI drivers which already supply exact time stamps
996          for events (i.e. for offline rendering based MIDI drivers)
997        - added checks for bad MIDI data
998    
999      * linuxsampler application:
1000        - show available sampler engine types on startup
1001    
1002    * general changes:    * general changes:
1003      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new
1004        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new        LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1005        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were        fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1006        introduced for this, the behavior is the same like on a mixer console        introduced for this, the behavior is the same like on a mixer console
1007        (patch by Grigor Iliev, a bit adjusted)        (patch by Grigor Iliev, a bit adjusted). Also added configure option
1008          --enable-process-muted-channels which can be used to enable the
1009          processing of muted channels.
1010        - support for sostenuto pedal
1011        - support for monitoring the total number of active voices
1012          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1013          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1014        - fixed some memory management errors
1015        - fixed some concurrency problems that could lead to crashes when
1016          LSCP commands were executed
1017        - fixed crash when instrument loading failed previously on the same
1018          sampler channel (fixes bug #36)
