2    
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
26        - removed usage of deprecated Automake variable INCLUDES
27        - fixed building with C++11
28        - build fix: ChangeFlagRelaxed.h was missing in makefile
29        - build fix: libsndfile compiler flags were missing in some
30          makefiles
31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34    
35      * general changes:
36        - Refactoring: moved the independent code from
37          the Gigasampler format engine to base classes
38        - command line option '--profile' is currently disabled, since the
39          respective profiling code is currently broken
40        - Introduced support for optional environment variable
41          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
42          where the sampler shall look for instrument editor plugins
43          (patch by Luis Garrido, slightly modified).
44        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
45        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
46        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
47          note (in this implementation of the sampler its simply hard routed to
48          the 1st effect send of the sampler channel, no matter what the actual
49          effect type is)
50        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
51          note (in this implementation of the sampler its simply hard routed to
52          the 2nd effect send of the sampler channel, no matter what the actual
53          effect type is)
54        - implemented support for internal LADSPA effects
55        - raised limit of program change queue from 100 to 512
56          (as suggested by Alex Stone)
57        - implemented sine LFO, pulse LFO and saw LFO
58        - experimental support for per voice equalization
59        - added command line option --exec-after-init
60        - Introduced new C++ API method:
61          EngineChannel::InstrumentFileName(int index)
62          allowing to retrieve the whole list of files used for the loaded
63          instrument on an engine channel (a.k.a. part). Some GigaStudio
64          instruments for example are splitted over several files like
65          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
66        - Added new C++ API method Sampler::GetGlobalMaxVoices().
67        - Added new C++ API method Sampler::GetGlobalMaxStreams().
68        - Added new C++ API method Sampler::SetGlobalMaxVoices().
69        - Added new C++ API method Sampler::SetGlobalMaxStreams().
70        - Various "const" and "restrict" optimizations.
71        - all engines: add pan CC value to instrument pan parameter before
72          applying panning, instead of using two separate pan functions in
73          series (#182)
74        - added a lock guard class for exception safe mutex handling and
75          used it everywhere appropriate
76        - Immediately apply scale tuning changes to active voices.
77        - Exposed scale tuning to C++ API (along to the already existing standard
78          SysEx way).
79        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
80          and broken for ppc64. (Seq_cst loads and stores are actually not
81          used in LS, so the bug wasn't noticable.)
82        - lsatomic.h: added ARMv7 support
83    
84      * Gigasampler format engine:
85        - implemented the "round robin keyboard" dimension
86        - fixed round robin and random dimensions for cases when number of
87          dimension zones is not a power of two
88        - made round robin use a counter for each region instead of each
89          key
90        - bugfix: pitch LFO controller "internal+aftertouch" was broken
91        - bugfix: filter keyboard tracking was broken
92        - filter performance fix (an unnecessary copy was made of the
93          filter parameters in each sub fragment)
94        - handle special case when pan parameter in gig file has max or
95          min value
96        - Exclusive Groups: don't ever stop voices of the same note,
97          doesn't sound naturally with a drumkit
98        - fixed EG1 modulation when attack or release is zero
99    
100      * SFZ format engine:
101        - Initial implementation (not usable yet)
102        - added support for v2 multiple stage envelope generators
103        - added a fine-tuned v1 envelope generator instead of using the
104          one from the gig engine
105        - fixed memory leak and memory handling errors
106        - added support for trigger=first, trigger=legato and sw_previous
107        - allow non-numerical key values ("C#4" for example)
108        - "key" opcode now sets pitch_keycenter too
109        - fixed error when unloading instrument with same sample used by
110          multiple regions
111        - added some opcode aliases, like loopmode for loop_mode, to be
112          more compatible
113        - added support for trigger=release and rt_decay

270        - Listen to all interfaces on Mac OS X (INADDR_ANY)
271        - VST bugfix: If the host called resume() before and after
272          changing sample rate or block size, the number of channels was
273          incorrectly set to two. This caused silence in Cubase 5.
274        - save engine type (gig, sfz or sf2) in plugin state
275        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
276          64 bit Windows
277        - AU: changed number of output channels from one stereo to 16
278          stereo
279        - VST: made it possible to build the VST plugin for Mac

286          loaded a second time (this time it's for Linux and Mac, previous
287          similar fix was for Windows)
288        - thread safety fixes for the instrument loading thread
289        - LV2: use the new lv2 package if present
290        - VST: try to open Fantasia automatically on Linux and Mac too (on
291          Linux, the Fantasia jar should be placed in <prefix>/share/java)
292        - VST: fixed crashes on Linux Ardour and EnergyXT
293        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
294          port and audio channel routing for DSSI plugins are now visible.
295        - LV2: use urid and atom extensions instead of deprecated uri-map
296          and event
297        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
298        - LV2: changed number of output channels to 16 stereo, just like
299          the VST and AU plugins
300        - LV2: fixed save/restore of SFZ state (patch by David Robillard)

307          the ALSA sequencer client name
308        - removed limit of maximum amount of MIDI ports per MIDI device, since
309          there is no reason for this limit
310        - MME: fixed memory handling bug found with cppcheck
311        - MME: removed compiler warning
312        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
313          which allows to retrieve the list of CoreMIDI clients / ports and to connect
314          to them a la JACK, via the usual sampler APIs
315        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
316          the driver will automatically connect to other CoreMIDI clients' ports
317          (e.g. external MIDI devices being attached to the Mac)
318        - added support for MIDI note on velocity filter
319        - CoreMIDI: fixed memory deallocation error
320        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

323        - Implemented missing handling of MIDI "running status".
324        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
325        - MME bugfix: driver wasn't closed properly
326    
327      * audio driver:
328        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
329        - JACK audio: react on sample rate changes.
330        - JACK audio: react on buffer size changes.
331        - JACK audio: jack_port_get_buffer() was cached and called outside

373      * Bug fixes:
374        - Fixed crash which may occur when MIDI key + transpose is out of range
375        - minor valgrind fixes
376        - fixed crash which occurred when changing an already deployed sampler
377          channel to a different engine type
378        - fixed crash when deleting a sampler channel or changing engine
379          type while an instrument load was in progress
380        - bugfix: playing a note while changing the instrument could cause
381          a crash, or give "Handing back unknown region" error messages
382        - bugfix: calling SET VOICES (which Fantasia does on start and
383          refresh) could cause instruments to be unloaded
384        - Mac OS X: fixed name collision of enum in EffectControl and
385          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
386        - Mac OS X: fixed hanging threads
387        - Windows: disabled the previous thread fix on non-Mac systems, as
388          it caused hanging threads on Windows
389        - Fixed possible crashes due to corrupted MIDI/audio device list
390          after MIDI/audio device creation failure
391        - When creating MIDI instrument map entries with "PERSISTENT" type, the
392          instruments were uselessly precached with zero samples, however it still
393          took the full preloading time and on 1st program change the respective
394          instrument was completely reloaded again.
395        - fixed handling of rapid bank select and program change messages
396          sent to the same sampler channel (patch from the Open Octave
397          project, slightly adjusted)
398        - fixed crash when trying to create an effect instance with controls
399          which min and/or max values depend on the sample rate

408        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
409        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
410          introduced in previous fix)
411        - fixed crash when a channel received a program change while
412          playing a note in a key group
413        - fixed erroneous error message piping in VoiceBase.h
414          (labelled "Disk stream not available in time")
415        - Update effects on sample rate & period size changes (to avoid
416          crashes and noise on such transitions).
417    
418    Version 1.0.0 (31 July 2009)
419    
420      * packaging changes:
421        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
422          causing e.g. the libgig test to fail when
423          "./configure --disable-jack-driver" was used
424          (patch by Alexis Ballier)
425        - fixed compilation with gcc 4.3
426        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
427        - fixed configure so it detects x86_64 (#107)
428        - fixes for building with newer MinGW versions
429        - fix for building with bison 2.4 (#111)
430        - fixed building with libgig installed in a non-standard directory
431        - minor fix in configure for mmsystem.h detection on MinGW
432        - Windows: look for editor plugins and Fantasia using base
433          directory of liblinuxsampler dll (look in the same directory and one
434          directory above)
435        - configure script fix: removed unconditional use of SSE
436        - fixed building with sqlite installed in a non-standard directory
437        - when cross-compiling, don't try to create instruments.db
438        - fix for new mingw-w64 version, which has usleep
439    
440      * general changes:
441        - bugfix: on some POSIX systems instrument editor plugins refused to
442          load as we used a non-portable Linux specific struct field
443          (fixes bug #70, patch by Ronald Baljeu)
444        - fixed endless loop which occured when loading an instrument editor
445          plugin DLL on Windows systems failed
446        - fixed memory leaks that occurred when liblinuxsampler was unloaded
447        - optimized the SynchronizedConfig class so it doesn't wait
448          unnecessarily long after an update
449        - added support for notifying instrument editors on note-on / note-off
450          events (e.g. to highlight the pressed keys on the virtual keyboard
451          of gigedit)
452        - added support for triggering notes by instrument editors (see above)
453        - be verbose on DLL load errors (on Linux)
454        - fixed di-harmonic triangle LFO implementation (this LFO implementation
455          is only used by very few systems, most pick the int math
456          implementation, which is usually faster)
457        - fixes for audio drivers with varying buffer sizes
458        - experimental support for running LinuxSampler as a DSSI, LV2 and
459          VST plugin
460        - notification events for stream/voice count statistics are now sent
461          only when there are actual changes
462        - added memory ordering constraints to improve stability on
463          multi-core and multi-cpu systems
464        - maximum voices and disk streams can now be altered at runtime
465        - fixed CPU feature detection on x86_64 (maybe fixes #108)
466        - automatic stacktrace mechanism is now turned off by default and can
467          be switched on by command line option "--stacktrace" (the automatic
468          stacktrace mechanism seems to be broken on most systems at the moment)
469        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
470          a pointer to the launched InstrumentEditor object
471        - added optional 3rd party user data parameter for following
472          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
473          InstrumentEditor::Launch(),
474          InstrumentManager::LaunchInstrumentEditor()
475        - theoretical fix: made SynchronizedConfig follow C++0x memory
476          model more strictly
477        - fixes for using large audio device buffers
478        - Windows: add the installation directory to the DLL search path
479          when loading an editor plugin (solves problems with VST and
480          gigedit on systems with other GTK versions installed)
481    
482      * audio driver:
483        - removed the nonsense audio channel constraint (which was hard coded to
484          max. 100 audio channels) for most audio drivers
485        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
486          opposed to the LSCP specs
487        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
488          reflected the wrong value
489        - fixed a memory management bug in ASIO driver
490        - Makefile fix: JACK_CFLAGS wasn't used
491        - JACK: use jack_client_open instead of the deprecated
492          jack_client_new
493        - added (experimental) CoreAudio driver
494        - applied old fixes to the ASIO driver that were included in the
495          previous binary release but accidentally never committed to CVS
496          (fixes #117)
497        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
498          win64)
499        - VST: added support for sample rate and buffer size changes
500        - VST: close editor (Fantasia) when the VST is removed
501        - VST: avoid opening Fantasia more than once for each VST instance
502        - VST: export main function as "main" on Linux too (fix for
503          energyXT)
504        - VST: changed number of output channels from one stereo to 16
505          stereo
506        - added channel routing, fxsends and midi maps to the settings
507          stored in the plugin state
508        - performance optimization of AudioChannel::MixTo() and
509          AudioChannel::CopyTo() methods using GCC vector exensions
510          (if available)
511        - ASIO fixes: avoid initializing the device twice, avoid throwing
512          exception when getting parameters from a disconnected device
513    
514      * MIDI driver:
515        - added JACK MIDI driver
516        - dispatch bank select as ordinary CC as well, the user might seriously
517          want to (mis)use it for some purpose ("fixed" in all current MIDI
518          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
519        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
520          CoreMidi or AU
521        - fixed mingw-w64 compilation error in MME driver
522        - made program change handling in MIDI thread real-time safe by
523          moving the logic to a non-RT thread
524        - fixed minor memory leak in ALSA driver
525    
526      * instruments database:
527        - avoid time consuming samples scanning when adding instruments
528          to the instruments database
529        - added support for handling lost files in the instruments database
530        - Implemented option for adding instruments in separate directories
531          in the instruments database
532          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
533        - work-around for missing fnmatch function on Windows to make
534          instrument database compilable
535        - added instrument database support on Windows
536          works with both standalone mode and VST plugin.
537          the instruments DB file is located in
538          %USERPROFILE%\.linuxsampler\instruments.db which allows different
539          databases for each windows user
540          if no DB is present it automatically creates the .linuxsampler subdir
541          and then creates an empty DB
542        - fixed recursive import, which was broken on Windows
543    
544      * Gigasampler format engine:
545        - fixed a memory leak that could happen when a channel was deleted
546          while notes were playing
547        - made it possible to load an instrument even if the audio thread
548          isn't running
549        - added partial support for the "Controller Triggered" MIDI rule,
550          enough for piano gigs with pedal noise samples
551        - minor fix: only mark FX sends as being modified if really the
552          respective FX send MIDI controller was used
553        - added support for GM global device volume SysEx message
554          (can be selected at compile time to either apply globally to the
555          whole sampler [default] or only to the sampler channels that are
556          connected to the respective MIDI input port the SysEx message arrived
557          on)
558        - bugfix: notes triggered at position 0 in the audio buffer were
559          sometimes wrongly killed in the same buffer, causing no sound to
560          be played
561        - added support for chromatic / drumkit mode Roland GS Sysex message
562          which is usally used to switch a part between chromatic sounds and
563          drumkit sounds (as opposed to their common default setting of MIDI
564          part 10 being a drumkit part and all other ones chromatic parts), in
565          LS however one can switch between the first 16 MIDI instrument maps
566          defined for the sampler
567        - made it possible to create multiple sample channels even if the
568          audio thread isn't running
569        - fixed crash when removing channel with active voices (#116)
570        - bugfix: on sample reference changes (instrument editor), only
571          un-cache the respective sample if it's really not used by any
572          sampler engine anymore
573        - re-cache samples in case they were changed by an instrument editor,
574          e.g. when a sample was added while playing (#82)
575        - fixed hanging notes which occured when note-off event had the exact
576          same time stamp as the voice's note-on event and occured both in the
577          same audio fragment cycle (fixes bug #112)
578        - added support for the "fine tune" and "pitch bend range"
579          instrument-level gig parameters
580        - fixed minor artifacts in pitch bend handling
581        - added support for GS Reset SysEx message
582        - allow gig files to use unlimited downward pitch shifting
583        - added a limit check for upward pitch shifting
584        - bugfix: sometimes, when playing a note twice fast, the second
585          note was silent
586        - fixed crash happening when a pitch bend event arrived at the
587          same time a new instrument was loading
588    
589      * LSCP server:
590        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
591          react on MIDI data arriving on certain sampler channels (so far only
592          Note-On and Note-Off events are sent via this LSCP event)
593        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
594          react on MIDI data arriving on certain MIDI input devices (so far only
595          Note-On and Note-Off events are sent via this LSCP event)
596        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
597          SET DB_INSTRUMENT FILE_PATH
598        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
599          frontends to send MIDI messages to specific sampler channel
600        - added two additional fields to GET FILE INSTRUMENT INFO command -
601          KEY_BINDINGS and KEYSWITCH_BINDINGS
602        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
603          was incorrect
604        - Optimized the retrieval of the MIDI instrument mappings
605        - added new LSCP command "SET VOICES" to globally alter the maximum
606          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
607          be triggered respectively
608        - added new LSCP command "SET STREAMS" to globally alter the maximum
609          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
610          which will be triggered respectively
611        - bugfix: retry if "select" returns EINTR (this fixes a crash when
612          a gigedit file dialog is opened)
613        - close all connections when LSCPServer is deleted
614        - hard close of all sockets on exit
615        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
616          driver
617    
618      * Bug fixes:
619        - fixed a crash which occurs when removing a sampler channel waiting
620          to start instrument loading after another channel
621        - fixed a crash which occurs when removing a sampler channel with
622          instrument loading in progress (bug #113)
623        - fixed termination caused by uncaught exception when adding MIDI
624          instrument with PERSISTENT load mode
625        - fixed possible iterator invalidations when resetting the sampler
626        - fixed memory leaks when issuing the following LSCP commands:
627          GET AUDIO_OUTPUT_DRIVER INFO
628          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
629          GET MIDI_INPUT_DRIVER INFO
630          GET MIDI_INPUT_DRIVER_PARAMETER INFO
631        - fixed possible compilation error when sqlite is not present
632        - fixed orphaned pointers when setting maximum voices limit (bug #118)
633        - fixed crash when changing the audio output device of a sampler
634          channel with loaded instrument and start playing notes
635        - fixed endless loop in Engine::SuspendAll() (bug #120)
636        - fixed a low-level atomic load function that was broken on 64-bit
637          PowerPC, which probably could cause crashes on that platform
638        - fixed a memory management error which could cause a crash when a
639          plugin was unloaded
640        - bugfix: two private structs had the same name, which could cause
641          problems if the linker chose the wrong constructor
642        - fixed low-level ConditionServer usage bug that caused lockups on
643          Windows
644    
645    
646    Version 0.5.1 (6 December 2007)
647    
648      * packaging changes:
649        - added autoconf checks for pthread library
650        - added autoconf check for pthread bug found on certain NPTL-enabled
651          glibc versions (see Gentoo bug report #194076)
652        - added autoconf checks for MS Windows
653    
654      * general changes:
655        - bugfix: the thread used by an editor plugin didn't die when the
656          editor closed
657        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
658          out all the space. operator--() did not apply size_mask after
659          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
660          order to avoid problems with the _NonVolatileReader functions.
661        - bugfix: Stream.h: added a missing divide by BytesPerSample in
662          GetWriteSpace(). Since this function is currently only used in
663          the stream's qsort() compare function, it didn't trigger any
664          bugs.
665        - Resampler.h, Synthesizer.h: cubic interpolation now works in
666          24bit mode too. Faster method to read 24bit words on little
667          endian machines (x86): replaced 3 byte reads + shifts with a 1
668          unaligned 32bit read and shift
669        - experimental support for MS Windows (MIDI input via MME, AUDIO
670          output via ASIO)
671        - made handling of SIGINT signal (Ctrl-C) a bit more robust
672        - support for monitoring the total number of active disk streams
673          (new LSCP commands: GET TOTAL_STREAM_COUNT,
674          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
675    
676      * AUDIO driver:
677        - added Windows ASIO low latency audio driver
678    
679      * MIDI driver:
680        - added MME Windows MIDI driver
681    
682      * LSCP server:
683        - added support for Windows style path / filenames, however with
684          forward slash path separators instead of backslash
685          (i.e. "C:/foo/bar.gig")
686        - allow naughty liblscp to send non-string device parameters within
687          apostrophes as well
688        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
689          "LIST FILE INSTRUMENTS <file>" and
690          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
691          about an arbitrary instrument file on the system where the sampler is
692          running on
693    
694    Version 0.5.0 (15 October 2007)
695    
696      * packaging changes:
697        - config.h is not going to be installed along with liblinuxsampler's
698          API header files anymore
699        - only the API relevant header (and source) files will be exported to
700          the Doxygen API documentation (explicitly listed in Doxyfile.in)
701        - added completely new XCode project files for Mac OSX which is now
702          capable to execute our autoconf environment, thus no need anymore
703          to maintain the compile time configuration file (osx/version.h) for
704          OSX manually (patch by Toshi Nagata)
705        - fixed buggy boolean --enable-foo / --disable-foo configure script
706          parameters
707        - global.h now only covers global definitions that are needed for the
708          C++ API header files, all implementation internal global definitions
709          are now in global_private.h
710        - atomic.h is not exposed to the C++ API anymore
711        - no need to include config.h anymore for using LS's API header files
712        - fixed warnings in API doc generation
713    
714      * general changes:
715        - replaced the old, confusing MIDI program change mechanism by a
716          flexible MIDI instrument mapper which allows to map arbitrary
717          (MIDI bank, MIDI program) pairs with arbitrary
718          (engine type, instrument file, file index) triplets which will be
719          loaded on the respective channel when such MIDI program change
720          messages arrive, beside that, each entry allows to define a life-time
721          strategy for the instrument, so the user can define whether the
722          instrument should i.e. be permanently loaded (to be able to switch
723          quickly among sounds) or i.e. loaded just on demand when the
724          respective program change arrives (to safe RAM space), as well as a
725          global volume factor for each entry, so the user can adjust the volume
726          dynamic of his mapped instrument collection without having to modify
727          the instrument files, also one can manage arbitrary amount of such
728          MIDI instrument maps and assign each sampler channel individually
729          a certain map, so that i.e. separation of normal instruments and
730          drumkits is possible
731        - new notification events for tracking changes to audio/MIDI devices,
732          MIDI instrument maps, MIDI instruments, FX sends, global volume.
733        - sampler was limited to load max. 200 instruments in the background
734          due to a constant size RingBuffer FIFO which is now replaced by a
735          dynamic (unlimited) size std::list FIFO
736        - added FX sends, these allow to route audio signals to arbitrary audio
737          output channels for being processed by external effect processors
738          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
739          controllers
740        - global (sampler wide) volume can now be controlled at runtime
741        - Implemented new, improved notification system
742        - fixed compilation errors regarding OSX
743          (patch by Toshi Nagata)
744        - implemented instruments database
745        - added support for escape sequences to the instruments database
746        - added highly experimental support for on-the-fly instrument editing
747          within the sampler's process (by using instrument editor plugins),
748          you'll notice the new "Registered instrument editors:" message on
749          startup, added a new LSCP command:
750          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
751          to spawn a matching instrument editor for the instrument on the
752          given sampler channel, the plugin path can be overridden at compile
753          time with ./configure --enable-plugin-dir=/some/dir
754        - added experimental code for synchronizing instrument editors hosted
755          in the sampler's process to safely edit instruments while playing
756          without a crash (hopefully) by either suspending single regions
757          wherever possible or if unavoidable whole engine(s)
758        - fixed several issues in fundamental "Thread" class: set scheduling
759          policy and priority on thread level, set a minimum stack size for
760          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
761          threads simply inherited properties of starting thread instead of
762          setting their own policy and priority
763        - minor fix in our automatic stack trace mechanism on crashes, the
764          main process did not wait for the stack trace process to finish
765          its output
766        - fixed some minor memory leaks
767        - reenabled assembly features support, at the moment only for
768          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
769        - minor assembly fix in x86 features detection (don't use the PIC
770          register, to avoid relocations in the text segment at runtime)
771        - POSIX callback functions of Thread.h are hidden
772    
773      * MIDI driver:
774        - dispatch bank select (MSB and LSB) messages
775    
776      * audio driver:
777        - the ALSA audio output driver parameters now reflect the correct
778          parameter value ranges for the respective selected sound card
779          (patch by Till Wimmer, a bit fixed and extended)
780    
781      * Gigasampler format engine:
782        - if a filter is used and EG2 finishes before EG1, let the voice
783          die when EG2 has finished (this fixes a problem with clicks and
784          voice starvation for some gigs)
785        - playback is no longer disabled during instrument loading
786        - all notes playing on a channel that changes its instrument keep
787          playing with the old instrument until they get a note off
788          command
789        - EG fix: a release value of zero could cause noises or crash
790        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
791        - EG fine tuning: when attack is zero the EG starts at a level
792          above max sustain level, which means that there is a decay phase
793          even if sustain is 100%
794        - more EG fixes: the level could sometimes go below zero and cause
795          noises or crashes
796        - minor fix of EGDecay (patch by Toshi Nagata)
797        - fixed compiler error when --enable-override-filter-type was
798          supplied to the configure script (fixes #46)
799        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
800          instead of a fix value
801        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
802          127 (solo mode) only kill voices if the respective mode really
803          changed
804    
805      * LSCP server:
806        - fixed compile time error for old Bison versions
807          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
808        - parser now supports extended ASCII character set
809          (up to ASCII code 255, i.e. includes now umlauts and accents)
810        - filename arguments in LSCP commands now allow to use escape
811          sequences, that is directly literal as one of: \', \", \\, \n, \r,
812          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
813          code value like \xf2) (fixes bug #24)
814        - the following LSCP commands now also support escape sequences for at
815          least one of their text-based parameters (i.e. name, description):
816          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
817          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
818          "SET DB_INSTRUMENT_DIRECTORY NAME",
819          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
820          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
821          "FIND DB_INSTRUMENT_DIRECTORIES"
822        - returns verbose syntax errors (line and column where syntax error
823          occured, the unexpected character and the actually expected, possible
824          character(s), the latter only if less than 5 possibilities)
825        - made sure that LSCP syntax is not affected by gigedit locale
826          settings
827        - bugfix regarding strings parameter lists: all comma separated lists
828          of strings were treated as being one string containing commas
829          (fixes #57)
830    
831      * Bug fixes:
832        - fixed crash occurring on certain LSCP scripts (Bug 39)
833        - another thread safety fix for lscp "load engine" and "set
834          channel audio output device"
835        - fixed a crash which occurs when reassigning the same engine
836          on a sampler channel with connected MIDI device
837        - fixed a crash which occurs when changing the number of ports of a MIDI
838          device connected to a sampler channel to number less then or equal
839          to the index of the port to which the sampler channel is connected.
840        - The previous bindings were not been disconnected when altering
841          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
842          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
843        - The active stream/voice count statistic was incorrect.
844        - notification events were not been sent for some sampler
845          channel changes
846        - added default min and max values to restrict the number of allowed
847          audio output channels and MIDI input ports
848        - the connection to the PCM interface is now closed when destroying
849          an audio output device
850        - files with slash in their path or filename could not be loaded
851    
852      * test cases:
853        - updated and fixed (haven't been touched in a while)
854    
855    Version 0.4.0 (24 November 2006)
856    
857      * packaging changes:
858        - changed deprecated copyright attribute to license; added ldconfig
859          to post-(un)install steps; added devel package for liblinuxsampler;
860          to linuxsampler.spec (RPM)
861        - install necessary development header files for allowing 3rd party
862          applications to link against liblinuxsampler
863        - liblinuxsampler's API documentation can be generated with 'make docs'
864          (Doxygen required)
865        - added benchmark to automatically detect the best triangle LFO
866          implementation (currently either an integer math solution or a
867          di-harmonic approximation), automatic detection can be overriden
868          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
869          configure script argument though (mandatory for cross-compilation)
870        - do not automatically pick optimized gcc flags if the user already
871          provided some on his own (as CXXFLAGS)
872        - added compile time option to disable processing of All-Notes-Off MIDI
873          messages
874        - added compile time options to allow disabling the various audio and
875          MIDI drivers
876        - fixed automatic GCC CPU switch detection on PPC
877          (patch by Ebrahim Mayat)
878    
879      * Gigasampler format engine:
880        - extensive synthesis optimization
881          (reimplementation of EGs and LFO(s), removed synthesis parameter
882          prerendering and the synthesis parameter matrix in general, splitting
883          each audio fragment into subfragments now where each subfragment uses
884          constant pitch and filter coefficients. The volume coefficient is
885          linearly interpolated inside a subfragment, unless
886          --disable-interpolate-volume is set.)
887        - fine tuning of the EG modulation parameters
888        - improved filter cutoff calculation by adding support for the
889          following gig parameters: Cutoff freq (used when no cutoff
890          controller is defined), Control invert, Minimum cutoff, Velocity
891          curve and Velocity range. The keyboard tracking now scales
892          cutoff frequency instead of resonance.
893        - added support for gig parameter Resonance.
894        - fixed bug in sysex handling (patch by Juan Linietsky)
895        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
896          which can be overridden with --enable-global-attenuation
897        - EG fixes: made the length of "attack hold" stage more
898          accurate. Release stage can now start before attack stage
899          ends. Cancel release didn't work when sustain was zero. Attack
900          time now has a minimal value to prevent clicks.
901        - fixed pitch changes larger than one octave
902        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
903        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
904          all modes can be altered via standard GM messages, that is CC5 for
905          altering portamento time, CC65 for enabling / disabling portamento
906          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
907        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
908          parameter) and crossfade
909        - added support for the "attenuation controller threshold" gig
910          parameter
911        - added smoothing of volume changes caused by control change
912          messages
913        - sample loop parameters are now taken from the DimensionRegion
914          instead of the wave chunk
915        - fixed keyswitching for v3 gigs with a number of keyswitch splits
916          not equal to a power of two
917        - reimplementation of the filter algorithm. The new filter is more
918          accurate and supports all gig filter types, including bandreject
919          and lowpass turbo.
920        - real support for 24 bit samples - samples are not truncated to
921          16 bits anymore
922        - support for aftertouch (channel pressure, not polyphonic
923          aftertouch)
924        - LFO1 behaviour fixed (dampening from max volume instead of
925          amplifying from 0)
926    
927      * LSCP server:
928        - fixed application exit on broken pipe error (fixes bug #20)
929        - fixed the notification messages delay due to lack of
930          network activity (fixes bug #26)
931        - fixed parser bug which occured on space(s) within device parameters
932          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
933    
934      * audio driver:
935        - added aRts audio output driver (by no means RT safe)
936    
937      * MIDI driver:
938        - fixed legacy sysex code which caused dispatching of MIDI SysEx
939          messages several times instead of once
940        - API extension for MIDI drivers which already supply exact time stamps
941          for events (i.e. for offline rendering based MIDI drivers)
942        - added checks for bad MIDI data
943    
944      * linuxsampler application:
945        - show available sampler engine types on startup
946    
947      * general changes:
948        - support for muting sampler channels and solo mode of the same, two new
949          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
950          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
951          introduced for this, the behavior is the same like on a mixer console
952          (patch by Grigor Iliev, a bit adjusted). Also added configure option
953          --enable-process-muted-channels which can be used to enable the
954          processing of muted channels.
955        - support for sostenuto pedal
956        - support for monitoring the total number of active voices
957          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
958          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
959        - fixed some memory management errors
960        - fixed some concurrency problems that could lead to crashes when
961          LSCP commands were executed
962        - fixed crash when instrument loading failed previously on the same
963          sampler channel (fixes bug #36)
964    
965    Version 0.3.3 (15 July 2005)
966    
967      * packaging changes:
968        - fixed compilation with gcc 4.0
969    
970      * Gigasampler format engine:
971        - LFO preprocessing was performed even though the respective LFO was
972          disabled by the instrument patch (minor efficiency fix)
973        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
974          for volume ramp downs in the same fragment (needed for current voice
975          stealing implementation) then simply inform the user with a warning
976          about possible click sounds and reduce the volume ramp down
977          appropriately instead of cancelling the audio device connection
978    
979    Version 0.3.2 (24 June 2005)
980    
981      * packaging changes:
982      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
983        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
984      - hand-crafted assembly optimization code can be disabled with      - hand-crafted assembly optimization code can be disabled with
985        './configure --disable-asm' (definitely not recommended)        './configure --disable-asm' (definitely not recommended)
986    * support for the gig parameters for "release velocity response"      - fixed 'make dist' rule to include all necessary files
987      curves      - require automake (>= 1.5) for 'make -f Makefile.cvs'
988    * fine tuning of the EGADSR envelope        (due to 'dist-bzip2' automake option)
989    
990      * Gigasampler format engine:
991        - support for the gig parameters for "release velocity response" curves
992        - fine tuning of the EGADSR envelope
993        - volume of release triggered samples now depends on note-on velocity,
994          note length and gig parameter "release trigger decay" instead of
995          note-off velocity.
996        - revised voice stealing
997          (fixes crash and endless loop caused by voice stealing)
998        - don't reset scale tuning on instrument or audio output device change
999        - handle key group conflicts right at the beginning of each fragment
1000          instead of when the respective voice is actually launched
1001          (fixes undefined behavior if stolen voices belonged to a key group -
1002          this case was followed by a "killed voice survived" error message)
1003        - fixed minor issue with null/silence samples
1004          (those stole voices even though they don't need a voice at all which
1005          resulted in "voice stealing didn't work out" messages)
1006        - don't reset volume, pan, pitch and MIDI controller values on
1007          instrument or audio output device change
1008    
1009    * LSCP server:    * LSCP server:
1010      - fixed some crashes (patch by Grigor Iliev, fixes #19)      - fixed some crashes (patch by Grigor Iliev, fixes #19)
1011    * volume of release triggered samples now depends on note-on      - fixed LSCP event "CHANNEL_INFO" notification
1012      velocity, note length and gig parameter "release trigger decay"        (e.g. did not notify on volume changes or MIDI program change events)
1013      instead of note-off velocity.  
1014      * linuxsampler application:
1015        - added command line parameters --lscp-addr and --lscp-port to override
1016          default IP address and port of LSCP server
1017    
1018  Version 0.3.1 (24 May 2005)  Version 0.3.1 (24 May 2005)
