1    Version CVS HEAD (?)
2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).
31        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)

46    
47      * Gigasampler format engine:

49        - fixed round robin and random dimensions for cases when number of
50          dimension zones is not a power of two
51        - made round robin use a counter for each region instead of each
52          key
53    
54      * SFZ format engine:
55        - Initial implementation (not usable yet)
56        - added support for v2 multiple stage envelope generators

80        - optimized sample lookup
81        - improved support for exclusive groups (group, off_by and
82          off_mode)

254      * Bug fixes:
255        - Fixed crash which may occur when MIDI key + transpose is out of range
256        - minor valgrind fixes
257        - fixed crash which occurred when changing an already deployed sampler
258          channel to a different engine type
259        - fixed crash when deleting a sampler channel or changing engine
260          type while an instrument load was in progress
261        - bugfix: playing a note while changing the instrument could cause
262          a crash, or give "Handing back unknown region" error messages
263        - bugfix: calling SET VOICES (which Fantasia does on start and
264          refresh) could cause instruments to be unloaded
265        - Mac OS X: fixed name collision of enum in EffectControl and
266          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
267        - Mac OS X: fixed hanging threads
268        - Windows: disabled the previous thread fix on non-Mac systems, as
269          it caused hanging threads on Windows
270        - Fixed possible crashes due to corrupted MIDI/audio device list
271          after MIDI/audio device creation failure
272        - When creating MIDI instrument map entries with "PERSISTENT" type, the
273          instruments were uselessly precached with zero samples, however it still
274          took the full preloading time and on 1st program change the respective
275          instrument was completely reloaded again.
276        - fixed handling of rapid bank select and program change messages
277          sent to the same sampler channel (patch from the Open Octave
278          project, slightly adjusted)
279        - fixed crash when trying to create an effect instance with controls
280          which min and/or max values depend on the sample rate
281    
282    Version 1.0.0 (31 July 2009)
283    
284      * packaging changes:
285        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
286          causing e.g. the libgig test to fail when
287          "./configure --disable-jack-driver" was used
288          (patch by Alexis Ballier)
289        - fixed compilation with gcc 4.3
290        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
291        - fixed configure so it detects x86_64 (#107)
292        - fixes for building with newer MinGW versions
293        - fix for building with bison 2.4 (#111)
294        - fixed building with libgig installed in a non-standard directory
295        - minor fix in configure for mmsystem.h detection on MinGW
296        - Windows: look for editor plugins and Fantasia using base
297          directory of liblinuxsampler dll (look in the same directory and one
298          directory above)
299        - configure script fix: removed unconditional use of SSE
300        - fixed building with sqlite installed in a non-standard directory
301        - when cross-compiling, don't try to create instruments.db
302        - fix for new mingw-w64 version, which has usleep
303    
304      * general changes:
305        - bugfix: on some POSIX systems instrument editor plugins refused to
306          load as we used a non-portable Linux specific struct field
307          (fixes bug #70, patch by Ronald Baljeu)
308        - fixed endless loop which occured when loading an instrument editor
309          plugin DLL on Windows systems failed
310        - fixed memory leaks that occurred when liblinuxsampler was unloaded
311        - optimized the SynchronizedConfig class so it doesn't wait
312          unnecessarily long after an update
313        - added support for notifying instrument editors on note-on / note-off
314          events (e.g. to highlight the pressed keys on the virtual keyboard
315          of gigedit)
316        - added support for triggering notes by instrument editors (see above)
317        - be verbose on DLL load errors (on Linux)
318        - fixed di-harmonic triangle LFO implementation (this LFO implementation
319          is only used by very few systems, most pick the int math
320          implementation, which is usually faster)
321        - fixes for audio drivers with varying buffer sizes
322        - experimental support for running LinuxSampler as a DSSI, LV2 and
323          VST plugin
324        - notification events for stream/voice count statistics are now sent
325          only when there are actual changes
326        - added memory ordering constraints to improve stability on
327          multi-core and multi-cpu systems
328        - maximum voices and disk streams can now be altered at runtime
329        - fixed CPU feature detection on x86_64 (maybe fixes #108)
330        - automatic stacktrace mechanism is now turned off by default and can
331          be switched on by command line option "--stacktrace" (the automatic
332          stacktrace mechanism seems to be broken on most systems at the moment)
333        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
334          a pointer to the launched InstrumentEditor object
335        - added optional 3rd party user data parameter for following
336          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
337          InstrumentEditor::Launch(),
338          InstrumentManager::LaunchInstrumentEditor()
339        - theoretical fix: made SynchronizedConfig follow C++0x memory
340          model more strictly
341        - fixes for using large audio device buffers
342        - Windows: add the installation directory to the DLL search path
343          when loading an editor plugin (solves problems with VST and
344          gigedit on systems with other GTK versions installed)
345    
346      * audio driver:
347        - removed the nonsense audio channel constraint (which was hard coded to
348          max. 100 audio channels) for most audio drivers
349        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
350          opposed to the LSCP specs
351        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
352          reflected the wrong value
353        - fixed a memory management bug in ASIO driver
354        - Makefile fix: JACK_CFLAGS wasn't used
355        - JACK: use jack_client_open instead of the deprecated
356          jack_client_new
357        - added (experimental) CoreAudio driver
358        - applied old fixes to the ASIO driver that were included in the
359          previous binary release but accidentally never committed to CVS
360          (fixes #117)
361        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
362          win64)
363        - VST: added support for sample rate and buffer size changes
364        - VST: close editor (Fantasia) when the VST is removed
365        - VST: avoid opening Fantasia more than once for each VST instance
366        - VST: export main function as "main" on Linux too (fix for
367          energyXT)
368        - VST: changed number of output channels from one stereo to 16
369          stereo
370        - added channel routing, fxsends and midi maps to the settings
371          stored in the plugin state
372        - performance optimization of AudioChannel::MixTo() and
373          AudioChannel::CopyTo() methods using GCC vector exensions
374          (if available)
375        - ASIO fixes: avoid initializing the device twice, avoid throwing
376          exception when getting parameters from a disconnected device
377    
378      * MIDI driver:
379        - added JACK MIDI driver
380        - dispatch bank select as ordinary CC as well, the user might seriously
381          want to (mis)use it for some purpose ("fixed" in all current MIDI
382          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
383        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
384          CoreMidi or AU
385        - fixed mingw-w64 compilation error in MME driver
386        - made program change handling in MIDI thread real-time safe by
387          moving the logic to a non-RT thread
388        - fixed minor memory leak in ALSA driver
389    
390      * instruments database:
391        - avoid time consuming samples scanning when adding instruments
392          to the instruments database
393        - added support for handling lost files in the instruments database
394        - Implemented option for adding instruments in separate directories
395          in the instruments database
396          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
397        - work-around for missing fnmatch function on Windows to make
398          instrument database compilable
399        - added instrument database support on Windows
400          works with both standalone mode and VST plugin.
401          the instruments DB file is located in
402          %USERPROFILE%\.linuxsampler\instruments.db which allows different
403          databases for each windows user
404          if no DB is present it automatically creates the .linuxsampler subdir
405          and then creates an empty DB
406        - fixed recursive import, which was broken on Windows
407    
408      * Gigasampler format engine:
409        - fixed a memory leak that could happen when a channel was deleted
410          while notes were playing
411        - made it possible to load an instrument even if the audio thread
412          isn't running
413        - added partial support for the "Controller Triggered" MIDI rule,
414          enough for piano gigs with pedal noise samples
415        - minor fix: only mark FX sends as being modified if really the
416          respective FX send MIDI controller was used
417        - added support for GM global device volume SysEx message
418          (can be selected at compile time to either apply globally to the
419          whole sampler [default] or only to the sampler channels that are
420          connected to the respective MIDI input port the SysEx message arrived
421          on)
422        - bugfix: notes triggered at position 0 in the audio buffer were
423          sometimes wrongly killed in the same buffer, causing no sound to
424          be played
425        - added support for chromatic / drumkit mode Roland GS Sysex message
426          which is usally used to switch a part between chromatic sounds and
427          drumkit sounds (as opposed to their common default setting of MIDI
428          part 10 being a drumkit part and all other ones chromatic parts), in
429          LS however one can switch between the first 16 MIDI instrument maps
430          defined for the sampler
431        - made it possible to create multiple sample channels even if the
432          audio thread isn't running
433        - fixed crash when removing channel with active voices (#116)
434        - bugfix: on sample reference changes (instrument editor), only
435          un-cache the respective sample if it's really not used by any
436          sampler engine anymore
437        - re-cache samples in case they were changed by an instrument editor,
438          e.g. when a sample was added while playing (#82)
439        - fixed hanging notes which occured when note-off event had the exact
440          same time stamp as the voice's note-on event and occured both in the
441          same audio fragment cycle (fixes bug #112)
442        - added support for the "fine tune" and "pitch bend range"
443          instrument-level gig parameters
444        - fixed minor artifacts in pitch bend handling
445        - added support for GS Reset SysEx message
446        - allow gig files to use unlimited downward pitch shifting
447        - added a limit check for upward pitch shifting
448        - bugfix: sometimes, when playing a note twice fast, the second
449          note was silent
450        - fixed crash happening when a pitch bend event arrived at the
451          same time a new instrument was loading
452    
453      * LSCP server:
454        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
455          react on MIDI data arriving on certain sampler channels (so far only
456          Note-On and Note-Off events are sent via this LSCP event)
457        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
458          react on MIDI data arriving on certain MIDI input devices (so far only
459          Note-On and Note-Off events are sent via this LSCP event)
460        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
461          SET DB_INSTRUMENT FILE_PATH
462        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
463          frontends to send MIDI messages to specific sampler channel
464        - added two additional fields to GET FILE INSTRUMENT INFO command -
465          KEY_BINDINGS and KEYSWITCH_BINDINGS
466        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
467          was incorrect
468        - Optimized the retrieval of the MIDI instrument mappings
469        - added new LSCP command "SET VOICES" to globally alter the maximum
470          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
471          be triggered respectively
472        - added new LSCP command "SET STREAMS" to globally alter the maximum
473          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
474          which will be triggered respectively
475        - bugfix: retry if "select" returns EINTR (this fixes a crash when
476          a gigedit file dialog is opened)
477        - close all connections when LSCPServer is deleted
478        - hard close of all sockets on exit
479        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
480          driver
481    
482      * Bug fixes:
483        - fixed a crash which occurs when removing a sampler channel waiting
484          to start instrument loading after another channel
485        - fixed a crash which occurs when removing a sampler channel with
486          instrument loading in progress (bug #113)
487        - fixed termination caused by uncaught exception when adding MIDI
488          instrument with PERSISTENT load mode
489        - fixed possible iterator invalidations when resetting the sampler
490        - fixed memory leaks when issuing the following LSCP commands:
491          GET AUDIO_OUTPUT_DRIVER INFO
492          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
493          GET MIDI_INPUT_DRIVER INFO
494          GET MIDI_INPUT_DRIVER_PARAMETER INFO
495        - fixed possible compilation error when sqlite is not present
496        - fixed orphaned pointers when setting maximum voices limit (bug #118)
497        - fixed crash when changing the audio output device of a sampler
498          channel with loaded instrument and start playing notes
499        - fixed endless loop in Engine::SuspendAll() (bug #120)
500        - fixed a low-level atomic load function that was broken on 64-bit
501          PowerPC, which probably could cause crashes on that platform
502        - fixed a memory management error which could cause a crash when a
503          plugin was unloaded
504        - bugfix: two private structs had the same name, which could cause
505          problems if the linker chose the wrong constructor
506        - fixed low-level ConditionServer usage bug that caused lockups on
507          Windows
508    
509    
510    Version 0.5.1 (6 December 2007)
511    
512      * packaging changes:
513        - added autoconf checks for pthread library
514        - added autoconf check for pthread bug found on certain NPTL-enabled
515          glibc versions (see Gentoo bug report #194076)
516        - added autoconf checks for MS Windows
517    
518      * general changes:
519        - bugfix: the thread used by an editor plugin didn't die when the
520          editor closed
521        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
522          out all the space. operator--() did not apply size_mask after
523          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
524          order to avoid problems with the _NonVolatileReader functions.
525        - bugfix: Stream.h: added a missing divide by BytesPerSample in
526          GetWriteSpace(). Since this function is currently only used in
527          the stream's qsort() compare function, it didn't trigger any
528          bugs.
529        - Resampler.h, Synthesizer.h: cubic interpolation now works in
530          24bit mode too. Faster method to read 24bit words on little
531          endian machines (x86): replaced 3 byte reads + shifts with a 1
532          unaligned 32bit read and shift
533        - experimental support for MS Windows (MIDI input via MME, AUDIO
534          output via ASIO)
535        - made handling of SIGINT signal (Ctrl-C) a bit more robust
536        - support for monitoring the total number of active disk streams
537          (new LSCP commands: GET TOTAL_STREAM_COUNT,
538          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
539    
540      * AUDIO driver:
541        - added Windows ASIO low latency audio driver
542    
543      * MIDI driver:
544        - added MME Windows MIDI driver
545    
546      * LSCP server:
547        - added support for Windows style path / filenames, however with
548          forward slash path separators instead of backslash
549          (i.e. "C:/foo/bar.gig")
550        - allow naughty liblscp to send non-string device parameters within
551          apostrophes as well
552        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
553          "LIST FILE INSTRUMENTS <file>" and
554          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
555          about an arbitrary instrument file on the system where the sampler is
556          running on
557    
558    Version 0.5.0 (15 October 2007)
559    
560      * packaging changes:
561        - config.h is not going to be installed along with liblinuxsampler's
562          API header files anymore
563        - only the API relevant header (and source) files will be exported to
564          the Doxygen API documentation (explicitly listed in Doxyfile.in)
565        - added completely new XCode project files for Mac OSX which is now
566          capable to execute our autoconf environment, thus no need anymore
567          to maintain the compile time configuration file (osx/version.h) for
568          OSX manually (patch by Toshi Nagata)
569        - fixed buggy boolean --enable-foo / --disable-foo configure script
570          parameters
571        - global.h now only covers global definitions that are needed for the
572          C++ API header files, all implementation internal global definitions
573          are now in global_private.h
574        - atomic.h is not exposed to the C++ API anymore
575        - no need to include config.h anymore for using LS's API header files
576        - fixed warnings in API doc generation
577    
578      * general changes:
579        - replaced the old, confusing MIDI program change mechanism by a
580          flexible MIDI instrument mapper which allows to map arbitrary
581          (MIDI bank, MIDI program) pairs with arbitrary
582          (engine type, instrument file, file index) triplets which will be
583          loaded on the respective channel when such MIDI program change
584          messages arrive, beside that, each entry allows to define a life-time
585          strategy for the instrument, so the user can define whether the
586          instrument should i.e. be permanently loaded (to be able to switch
587          quickly among sounds) or i.e. loaded just on demand when the
588          respective program change arrives (to safe RAM space), as well as a
589          global volume factor for each entry, so the user can adjust the volume
590          dynamic of his mapped instrument collection without having to modify
591          the instrument files, also one can manage arbitrary amount of such
592          MIDI instrument maps and assign each sampler channel individually
593          a certain map, so that i.e. separation of normal instruments and
594          drumkits is possible
595        - new notification events for tracking changes to audio/MIDI devices,
596          MIDI instrument maps, MIDI instruments, FX sends, global volume.
597        - sampler was limited to load max. 200 instruments in the background
598          due to a constant size RingBuffer FIFO which is now replaced by a
599          dynamic (unlimited) size std::list FIFO
600        - added FX sends, these allow to route audio signals to arbitrary audio
601          output channels for being processed by external effect processors
602          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
603          controllers
604        - global (sampler wide) volume can now be controlled at runtime
605        - Implemented new, improved notification system
606        - fixed compilation errors regarding OSX
607          (patch by Toshi Nagata)
608        - implemented instruments database
609        - added support for escape sequences to the instruments database
610        - added highly experimental support for on-the-fly instrument editing
611          within the sampler's process (by using instrument editor plugins),
612          you'll notice the new "Registered instrument editors:" message on
613          startup, added a new LSCP command:
614          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
615          to spawn a matching instrument editor for the instrument on the
616          given sampler channel, the plugin path can be overridden at compile
617          time with ./configure --enable-plugin-dir=/some/dir
618        - added experimental code for synchronizing instrument editors hosted
619          in the sampler's process to safely edit instruments while playing
620          without a crash (hopefully) by either suspending single regions
621          wherever possible or if unavoidable whole engine(s)
622        - fixed several issues in fundamental "Thread" class: set scheduling
623          policy and priority on thread level, set a minimum stack size for
624          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
625          threads simply inherited properties of starting thread instead of
626          setting their own policy and priority
627        - minor fix in our automatic stack trace mechanism on crashes, the
628          main process did not wait for the stack trace process to finish
629          its output
630        - fixed some minor memory leaks
631        - reenabled assembly features support, at the moment only for
632          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
633        - minor assembly fix in x86 features detection (don't use the PIC
634          register, to avoid relocations in the text segment at runtime)
635        - POSIX callback functions of Thread.h are hidden
636    
637      * MIDI driver:
638        - dispatch bank select (MSB and LSB) messages
639    
640      * audio driver:
641        - the ALSA audio output driver parameters now reflect the correct
642          parameter value ranges for the respective selected sound card
643          (patch by Till Wimmer, a bit fixed and extended)
644    
645      * Gigasampler format engine:
646        - if a filter is used and EG2 finishes before EG1, let the voice
647          die when EG2 has finished (this fixes a problem with clicks and
648          voice starvation for some gigs)
649        - playback is no longer disabled during instrument loading
650        - all notes playing on a channel that changes its instrument keep
651          playing with the old instrument until they get a note off
652          command
653        - EG fix: a release value of zero could cause noises or crash
654        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
655        - EG fine tuning: when attack is zero the EG starts at a level
656          above max sustain level, which means that there is a decay phase
657          even if sustain is 100%
658        - more EG fixes: the level could sometimes go below zero and cause
659          noises or crashes
660        - minor fix of EGDecay (patch by Toshi Nagata)
661        - fixed compiler error when --enable-override-filter-type was
662          supplied to the configure script (fixes #46)
663        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
664          instead of a fix value
665        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
666          127 (solo mode) only kill voices if the respective mode really
667          changed
668    
669      * LSCP server:
670        - fixed compile time error for old Bison versions
671          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
672        - parser now supports extended ASCII character set
673          (up to ASCII code 255, i.e. includes now umlauts and accents)
674        - filename arguments in LSCP commands now allow to use escape
675          sequences, that is directly literal as one of: \', \", \\, \n, \r,
676          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
677          code value like \xf2) (fixes bug #24)
678        - the following LSCP commands now also support escape sequences for at
679          least one of their text-based parameters (i.e. name, description):
680          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
681          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
682          "SET DB_INSTRUMENT_DIRECTORY NAME",
683          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
684          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
685          "FIND DB_INSTRUMENT_DIRECTORIES"
686        - returns verbose syntax errors (line and column where syntax error
687          occured, the unexpected character and the actually expected, possible
688          character(s), the latter only if less than 5 possibilities)
689        - made sure that LSCP syntax is not affected by gigedit locale
690          settings
691        - bugfix regarding strings parameter lists: all comma separated lists
692          of strings were treated as being one string containing commas
693          (fixes #57)
694    
695      * Bug fixes:
696        - fixed crash occurring on certain LSCP scripts (Bug 39)
697        - another thread safety fix for lscp "load engine" and "set
698          channel audio output device"
699        - fixed a crash which occurs when reassigning the same engine
700          on a sampler channel with connected MIDI device
701        - fixed a crash which occurs when changing the number of ports of a MIDI
702          device connected to a sampler channel to number less then or equal
703          to the index of the port to which the sampler channel is connected.
704        - The previous bindings were not been disconnected when altering
705          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
706          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
707        - The active stream/voice count statistic was incorrect.
708        - notification events were not been sent for some sampler
709          channel changes
710        - added default min and max values to restrict the number of allowed
711          audio output channels and MIDI input ports
712        - the connection to the PCM interface is now closed when destroying
713          an audio output device
714        - files with slash in their path or filename could not be loaded
715    
716      * test cases:
717        - updated and fixed (haven't been touched in a while)
718    
719    Version 0.4.0 (24 November 2006)
720    
721      * packaging changes:
722        - changed deprecated copyright attribute to license; added ldconfig
723          to post-(un)install steps; added devel package for liblinuxsampler;
724          to linuxsampler.spec (RPM)
725        - install necessary development header files for allowing 3rd party
726          applications to link against liblinuxsampler
727        - liblinuxsampler's API documentation can be generated with 'make docs'
728          (Doxygen required)
729        - added benchmark to automatically detect the best triangle LFO
730          implementation (currently either an integer math solution or a
731          di-harmonic approximation), automatic detection can be overriden
732          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
733          configure script argument though (mandatory for cross-compilation)
734        - do not automatically pick optimized gcc flags if the user already
735          provided some on his own (as CXXFLAGS)
736        - added compile time option to disable processing of All-Notes-Off MIDI
737          messages
738        - added compile time options to allow disabling the various audio and
739          MIDI drivers
740        - fixed automatic GCC CPU switch detection on PPC
741          (patch by Ebrahim Mayat)
742    
743      * Gigasampler format engine:
744        - extensive synthesis optimization
745          (reimplementation of EGs and LFO(s), removed synthesis parameter
746          prerendering and the synthesis parameter matrix in general, splitting
747          each audio fragment into subfragments now where each subfragment uses
748          constant pitch and filter coefficients. The volume coefficient is
749          linearly interpolated inside a subfragment, unless
750          --disable-interpolate-volume is set.)
751        - fine tuning of the EG modulation parameters
752        - improved filter cutoff calculation by adding support for the
753          following gig parameters: Cutoff freq (used when no cutoff
754          controller is defined), Control invert, Minimum cutoff, Velocity
755          curve and Velocity range. The keyboard tracking now scales
756          cutoff frequency instead of resonance.
757        - added support for gig parameter Resonance.
758        - fixed bug in sysex handling (patch by Juan Linietsky)
759        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
760          which can be overridden with --enable-global-attenuation
761        - EG fixes: made the length of "attack hold" stage more
762          accurate. Release stage can now start before attack stage
763          ends. Cancel release didn't work when sustain was zero. Attack
764          time now has a minimal value to prevent clicks.
765        - fixed pitch changes larger than one octave
766        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
767        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
768          all modes can be altered via standard GM messages, that is CC5 for
769          altering portamento time, CC65 for enabling / disabling portamento
770          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
771        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
772          parameter) and crossfade
773        - added support for the "attenuation controller threshold" gig
774          parameter
775        - added smoothing of volume changes caused by control change
776          messages
777        - sample loop parameters are now taken from the DimensionRegion
778          instead of the wave chunk
779        - fixed keyswitching for v3 gigs with a number of keyswitch splits
780          not equal to a power of two
781        - reimplementation of the filter algorithm. The new filter is more
782          accurate and supports all gig filter types, including bandreject
783          and lowpass turbo.
784        - real support for 24 bit samples - samples are not truncated to
785          16 bits anymore
786        - support for aftertouch (channel pressure, not polyphonic
787          aftertouch)
788        - LFO1 behaviour fixed (dampening from max volume instead of
789          amplifying from 0)
790    
791      * LSCP server:
792        - fixed application exit on broken pipe error (fixes bug #20)
793        - fixed the notification messages delay due to lack of
794          network activity (fixes bug #26)
795        - fixed parser bug which occured on space(s) within device parameters
796          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
797    
798      * audio driver:
799        - added aRts audio output driver (by no means RT safe)
800    
801      * MIDI driver:
802        - fixed legacy sysex code which caused dispatching of MIDI SysEx
803          messages several times instead of once
804        - API extension for MIDI drivers which already supply exact time stamps
805          for events (i.e. for offline rendering based MIDI drivers)
806        - added checks for bad MIDI data
807    
808      * linuxsampler application:
809        - show available sampler engine types on startup
810    
811      * general changes:
812        - support for muting sampler channels and solo mode of the same, two new
813          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
814          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
815          introduced for this, the behavior is the same like on a mixer console
816          (patch by Grigor Iliev, a bit adjusted). Also added configure option
817          --enable-process-muted-channels which can be used to enable the
818          processing of muted channels.
819        - support for sostenuto pedal
820        - support for monitoring the total number of active voices
821          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
822          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
823        - fixed some memory management errors
824        - fixed some concurrency problems that could lead to crashes when
825          LSCP commands were executed
826        - fixed crash when instrument loading failed previously on the same
827          sampler channel (fixes bug #36)
