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).

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)

49          dimension zones is not a power of two
50        - made round robin use a counter for each region instead of each
51          key
52    
53      * SFZ format engine:
54        - Initial implementation (not usable yet)
55        - added support for v2 multiple stage envelope generators
56        - added a fine-tuned v1 envelope generator instead of using the
57          one from the gig engine

78        - fixed a bug that could cause voice stealing to fail
79        - optimized sample lookup
80        - improved support for exclusive groups (group, off_by and
81          off_mode)
82        - added support for controller triggered regions (on_locc/on_hicc)
83        - added support for loop_mode=one_shot
84        - fixed playback of 16 bit wav files on big endian CPUs

152        - bugfix: pitch LFO controller "internal+aftertouch" was broken
153        - bugfix: filter keyboard tracking was broken
154        - filter performance fix (an unnecessary copy was made of the

156    
157      * Host plugins:
158        - AU bugfix: failed to destroy its audio/MIDI devices
159        - Listen to all interfaces on Mac OS X (INADDR_ANY)
160        - VST bugfix: If the host called resume() before and after
161          changing sample rate or block size, the number of channels was
162          incorrectly set to two. This caused silence in Cubase 5.
163        - save engine type (gig, sfz or sf2) in plugin state
164        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

218      * Bug fixes:
219        - Fixed crash which may occur when MIDI key + transpose is out of range
220        - minor valgrind fixes
221        - fixed crash which occurred when changing an already deployed sampler
222          channel to a different engine type
223        - fixed crash when deleting a sampler channel or changing engine
224          type while an instrument load was in progress
225        - bugfix: playing a note while changing the instrument could cause
226          a crash, or give "Handing back unknown region" error messages
227        - bugfix: calling SET VOICES (which Fantasia does on start and
228          refresh) could cause instruments to be unloaded
229        - Mac OS X: fixed name collision of enum in EffectControl and
230          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
231        - Mac OS X: fixed hanging threads
232        - Windows: disabled the previous thread fix on non-Mac systems, as
233          it caused hanging threads on Windows
234        - Fixed possible crashes due to corrupted MIDI/audio device list
235          after MIDI/audio device creation failure
236    
237    Version 1.0.0 (31 July 2009)
238    
239      * packaging changes:
240        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
241          causing e.g. the libgig test to fail when
242          "./configure --disable-jack-driver" was used
243          (patch by Alexis Ballier)
244        - fixed compilation with gcc 4.3
245        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
246        - fixed configure so it detects x86_64 (#107)
247        - fixes for building with newer MinGW versions
248        - fix for building with bison 2.4 (#111)
249        - fixed building with libgig installed in a non-standard directory
250        - minor fix in configure for mmsystem.h detection on MinGW
251        - Windows: look for editor plugins and Fantasia using base
252          directory of liblinuxsampler dll (look in the same directory and one
253          directory above)
254        - configure script fix: removed unconditional use of SSE
255        - fixed building with sqlite installed in a non-standard directory
256        - when cross-compiling, don't try to create instruments.db
257        - fix for new mingw-w64 version, which has usleep
258    
259      * general changes:
260        - bugfix: on some POSIX systems instrument editor plugins refused to
261          load as we used a non-portable Linux specific struct field
262          (fixes bug #70, patch by Ronald Baljeu)
263        - fixed endless loop which occured when loading an instrument editor
264          plugin DLL on Windows systems failed
265        - fixed memory leaks that occurred when liblinuxsampler was unloaded
266        - optimized the SynchronizedConfig class so it doesn't wait
267          unnecessarily long after an update
268        - added support for notifying instrument editors on note-on / note-off
269          events (e.g. to highlight the pressed keys on the virtual keyboard
270          of gigedit)
271        - added support for triggering notes by instrument editors (see above)
272        - be verbose on DLL load errors (on Linux)
273        - fixed di-harmonic triangle LFO implementation (this LFO implementation
274          is only used by very few systems, most pick the int math
275          implementation, which is usually faster)
276        - fixes for audio drivers with varying buffer sizes
277        - experimental support for running LinuxSampler as a DSSI, LV2 and
278          VST plugin
279        - notification events for stream/voice count statistics are now sent
280          only when there are actual changes
281        - added memory ordering constraints to improve stability on
282          multi-core and multi-cpu systems
283        - maximum voices and disk streams can now be altered at runtime
284        - fixed CPU feature detection on x86_64 (maybe fixes #108)
285        - automatic stacktrace mechanism is now turned off by default and can
286          be switched on by command line option "--stacktrace" (the automatic
287          stacktrace mechanism seems to be broken on most systems at the moment)
288        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
289          a pointer to the launched InstrumentEditor object
290        - added optional 3rd party user data parameter for following
291          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
292          InstrumentEditor::Launch(),
293          InstrumentManager::LaunchInstrumentEditor()
294        - theoretical fix: made SynchronizedConfig follow C++0x memory
295          model more strictly
296        - fixes for using large audio device buffers
297        - Windows: add the installation directory to the DLL search path
298          when loading an editor plugin (solves problems with VST and
299          gigedit on systems with other GTK versions installed)
300    
301      * audio driver:
302        - removed the nonsense audio channel constraint (which was hard coded to
303          max. 100 audio channels) for most audio drivers
304        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
305          opposed to the LSCP specs
306        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
307          reflected the wrong value
308        - fixed a memory management bug in ASIO driver
309        - Makefile fix: JACK_CFLAGS wasn't used
310        - JACK: use jack_client_open instead of the deprecated
311          jack_client_new
312        - added (experimental) CoreAudio driver
313        - applied old fixes to the ASIO driver that were included in the
314          previous binary release but accidentally never committed to CVS
315          (fixes #117)
316        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
317          win64)
318        - VST: added support for sample rate and buffer size changes
319        - VST: close editor (Fantasia) when the VST is removed
320        - VST: avoid opening Fantasia more than once for each VST instance
321        - VST: export main function as "main" on Linux too (fix for
322          energyXT)
323        - VST: changed number of output channels from one stereo to 16
324          stereo
325        - added channel routing, fxsends and midi maps to the settings
326          stored in the plugin state
327        - performance optimization of AudioChannel::MixTo() and
328          AudioChannel::CopyTo() methods using GCC vector exensions
329          (if available)
330        - ASIO fixes: avoid initializing the device twice, avoid throwing
331          exception when getting parameters from a disconnected device
332    
333      * MIDI driver:
334        - added JACK MIDI driver
335        - dispatch bank select as ordinary CC as well, the user might seriously
336          want to (mis)use it for some purpose ("fixed" in all current MIDI
337          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
338        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
339          CoreMidi or AU
340        - fixed mingw-w64 compilation error in MME driver
341        - made program change handling in MIDI thread real-time safe by
342          moving the logic to a non-RT thread
343        - fixed minor memory leak in ALSA driver
344    
345      * instruments database:
346        - avoid time consuming samples scanning when adding instruments
347          to the instruments database
348        - added support for handling lost files in the instruments database
349        - Implemented option for adding instruments in separate directories
350          in the instruments database
351          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
352        - work-around for missing fnmatch function on Windows to make
353          instrument database compilable
354        - added instrument database support on Windows
355          works with both standalone mode and VST plugin.
356          the instruments DB file is located in
357          %USERPROFILE%\.linuxsampler\instruments.db which allows different
358          databases for each windows user
359          if no DB is present it automatically creates the .linuxsampler subdir
360          and then creates an empty DB
361        - fixed recursive import, which was broken on Windows
362    
363      * Gigasampler format engine:
364        - fixed a memory leak that could happen when a channel was deleted
365          while notes were playing
366        - made it possible to load an instrument even if the audio thread
367          isn't running
368        - added partial support for the "Controller Triggered" MIDI rule,
369          enough for piano gigs with pedal noise samples
370        - minor fix: only mark FX sends as being modified if really the
371          respective FX send MIDI controller was used
372        - added support for GM global device volume SysEx message
373          (can be selected at compile time to either apply globally to the
374          whole sampler [default] or only to the sampler channels that are
375          connected to the respective MIDI input port the SysEx message arrived
376          on)
377        - bugfix: notes triggered at position 0 in the audio buffer were
378          sometimes wrongly killed in the same buffer, causing no sound to
379          be played
380        - added support for chromatic / drumkit mode Roland GS Sysex message
381          which is usally used to switch a part between chromatic sounds and
382          drumkit sounds (as opposed to their common default setting of MIDI
383          part 10 being a drumkit part and all other ones chromatic parts), in
384          LS however one can switch between the first 16 MIDI instrument maps
385          defined for the sampler
386        - made it possible to create multiple sample channels even if the
387          audio thread isn't running
388        - fixed crash when removing channel with active voices (#116)
389        - bugfix: on sample reference changes (instrument editor), only
390          un-cache the respective sample if it's really not used by any
391          sampler engine anymore
392        - re-cache samples in case they were changed by an instrument editor,
393          e.g. when a sample was added while playing (#82)
394        - fixed hanging notes which occured when note-off event had the exact
395          same time stamp as the voice's note-on event and occured both in the
396          same audio fragment cycle (fixes bug #112)
397        - added support for the "fine tune" and "pitch bend range"
398          instrument-level gig parameters
399        - fixed minor artifacts in pitch bend handling
400        - added support for GS Reset SysEx message
401        - allow gig files to use unlimited downward pitch shifting
402        - added a limit check for upward pitch shifting
403        - bugfix: sometimes, when playing a note twice fast, the second
404          note was silent
405        - fixed crash happening when a pitch bend event arrived at the
406          same time a new instrument was loading
407    
408      * LSCP server:
409        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
410          react on MIDI data arriving on certain sampler channels (so far only
411          Note-On and Note-Off events are sent via this LSCP event)
412        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
413          react on MIDI data arriving on certain MIDI input devices (so far only
414          Note-On and Note-Off events are sent via this LSCP event)
415        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
416          SET DB_INSTRUMENT FILE_PATH
417        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
418          frontends to send MIDI messages to specific sampler channel
419        - added two additional fields to GET FILE INSTRUMENT INFO command -
420          KEY_BINDINGS and KEYSWITCH_BINDINGS
421        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
422          was incorrect
423        - Optimized the retrieval of the MIDI instrument mappings
424        - added new LSCP command "SET VOICES" to globally alter the maximum
425          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
426          be triggered respectively
427        - added new LSCP command "SET STREAMS" to globally alter the maximum
428          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
429          which will be triggered respectively
430        - bugfix: retry if "select" returns EINTR (this fixes a crash when
431          a gigedit file dialog is opened)
432        - close all connections when LSCPServer is deleted
433        - hard close of all sockets on exit
434        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
435          driver
436    
437      * Bug fixes:
438        - fixed a crash which occurs when removing a sampler channel waiting
439          to start instrument loading after another channel
440        - fixed a crash which occurs when removing a sampler channel with
441          instrument loading in progress (bug #113)
442        - fixed termination caused by uncaught exception when adding MIDI
443          instrument with PERSISTENT load mode
444        - fixed possible iterator invalidations when resetting the sampler
445        - fixed memory leaks when issuing the following LSCP commands:
446          GET AUDIO_OUTPUT_DRIVER INFO
447          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
448          GET MIDI_INPUT_DRIVER INFO
449          GET MIDI_INPUT_DRIVER_PARAMETER INFO
450        - fixed possible compilation error when sqlite is not present
451        - fixed orphaned pointers when setting maximum voices limit (bug #118)
452        - fixed crash when changing the audio output device of a sampler
453          channel with loaded instrument and start playing notes
454        - fixed endless loop in Engine::SuspendAll() (bug #120)
455        - fixed a low-level atomic load function that was broken on 64-bit
456          PowerPC, which probably could cause crashes on that platform
457        - fixed a memory management error which could cause a crash when a
458          plugin was unloaded
459        - bugfix: two private structs had the same name, which could cause
460          problems if the linker chose the wrong constructor
461        - fixed low-level ConditionServer usage bug that caused lockups on
462          Windows
463    
464    
465    Version 0.5.1 (6 December 2007)
466    
467      * packaging changes:
468        - added autoconf checks for pthread library
469        - added autoconf check for pthread bug found on certain NPTL-enabled
470          glibc versions (see Gentoo bug report #194076)
471        - added autoconf checks for MS Windows
472    
473      * general changes:
474        - bugfix: the thread used by an editor plugin didn't die when the
475          editor closed
476        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
477          out all the space. operator--() did not apply size_mask after
478          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
479          order to avoid problems with the _NonVolatileReader functions.
480        - bugfix: Stream.h: added a missing divide by BytesPerSample in
481          GetWriteSpace(). Since this function is currently only used in
482          the stream's qsort() compare function, it didn't trigger any
483          bugs.
484        - Resampler.h, Synthesizer.h: cubic interpolation now works in
485          24bit mode too. Faster method to read 24bit words on little
486          endian machines (x86): replaced 3 byte reads + shifts with a 1
487          unaligned 32bit read and shift
488        - experimental support for MS Windows (MIDI input via MME, AUDIO
489          output via ASIO)
490        - made handling of SIGINT signal (Ctrl-C) a bit more robust
491        - support for monitoring the total number of active disk streams
492          (new LSCP commands: GET TOTAL_STREAM_COUNT,
493          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
494    
495      * AUDIO driver:
496        - added Windows ASIO low latency audio driver
497    
498      * MIDI driver:
499        - added MME Windows MIDI driver
500    
501      * LSCP server:
502        - added support for Windows style path / filenames, however with
503          forward slash path separators instead of backslash
504          (i.e. "C:/foo/bar.gig")
505        - allow naughty liblscp to send non-string device parameters within
506          apostrophes as well
507        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
508          "LIST FILE INSTRUMENTS <file>" and
509          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
510          about an arbitrary instrument file on the system where the sampler is
511          running on
512    
513    Version 0.5.0 (15 October 2007)
514    
515      * packaging changes:
516        - config.h is not going to be installed along with liblinuxsampler's
517          API header files anymore
518        - only the API relevant header (and source) files will be exported to
519          the Doxygen API documentation (explicitly listed in Doxyfile.in)
520        - added completely new XCode project files for Mac OSX which is now
521          capable to execute our autoconf environment, thus no need anymore
522          to maintain the compile time configuration file (osx/version.h) for
523          OSX manually (patch by Toshi Nagata)
524        - fixed buggy boolean --enable-foo / --disable-foo configure script
525          parameters
526        - global.h now only covers global definitions that are needed for the
527          C++ API header files, all implementation internal global definitions
528          are now in global_private.h
529        - atomic.h is not exposed to the C++ API anymore
530        - no need to include config.h anymore for using LS's API header files
531        - fixed warnings in API doc generation
532    
533      * general changes:
534        - replaced the old, confusing MIDI program change mechanism by a
535          flexible MIDI instrument mapper which allows to map arbitrary
536          (MIDI bank, MIDI program) pairs with arbitrary
537          (engine type, instrument file, file index) triplets which will be
538          loaded on the respective channel when such MIDI program change
539          messages arrive, beside that, each entry allows to define a life-time
540          strategy for the instrument, so the user can define whether the
541          instrument should i.e. be permanently loaded (to be able to switch
542          quickly among sounds) or i.e. loaded just on demand when the
543          respective program change arrives (to safe RAM space), as well as a
544          global volume factor for each entry, so the user can adjust the volume
545          dynamic of his mapped instrument collection without having to modify
546          the instrument files, also one can manage arbitrary amount of such
547          MIDI instrument maps and assign each sampler channel individually
548          a certain map, so that i.e. separation of normal instruments and
549          drumkits is possible
550        - new notification events for tracking changes to audio/MIDI devices,
551          MIDI instrument maps, MIDI instruments, FX sends, global volume.
552        - sampler was limited to load max. 200 instruments in the background
553          due to a constant size RingBuffer FIFO which is now replaced by a
554          dynamic (unlimited) size std::list FIFO
555        - added FX sends, these allow to route audio signals to arbitrary audio
556          output channels for being processed by external effect processors
557          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
558          controllers
559        - global (sampler wide) volume can now be controlled at runtime
560        - Implemented new, improved notification system
561        - fixed compilation errors regarding OSX
562          (patch by Toshi Nagata)
563        - implemented instruments database
564        - added support for escape sequences to the instruments database
565        - added highly experimental support for on-the-fly instrument editing
566          within the sampler's process (by using instrument editor plugins),
567          you'll notice the new "Registered instrument editors:" message on
568          startup, added a new LSCP command:
569          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
570          to spawn a matching instrument editor for the instrument on the
571          given sampler channel, the plugin path can be overridden at compile
572          time with ./configure --enable-plugin-dir=/some/dir
573        - added experimental code for synchronizing instrument editors hosted
574          in the sampler's process to safely edit instruments while playing
575          without a crash (hopefully) by either suspending single regions
576          wherever possible or if unavoidable whole engine(s)
577        - fixed several issues in fundamental "Thread" class: set scheduling
578          policy and priority on thread level, set a minimum stack size for
579          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
580          threads simply inherited properties of starting thread instead of
581          setting their own policy and priority
582        - minor fix in our automatic stack trace mechanism on crashes, the
583          main process did not wait for the stack trace process to finish
584          its output
585        - fixed some minor memory leaks
586        - reenabled assembly features support, at the moment only for
587          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
588        - minor assembly fix in x86 features detection (don't use the PIC
589          register, to avoid relocations in the text segment at runtime)
590        - POSIX callback functions of Thread.h are hidden
591    
592      * MIDI driver:
593        - dispatch bank select (MSB and LSB) messages
594    
595      * audio driver:
596        - the ALSA audio output driver parameters now reflect the correct
597          parameter value ranges for the respective selected sound card
598          (patch by Till Wimmer, a bit fixed and extended)
599    
600      * Gigasampler format engine:
601        - if a filter is used and EG2 finishes before EG1, let the voice
602          die when EG2 has finished (this fixes a problem with clicks and
603          voice starvation for some gigs)
604        - playback is no longer disabled during instrument loading
605        - all notes playing on a channel that changes its instrument keep
606          playing with the old instrument until they get a note off
607          command
608        - EG fix: a release value of zero could cause noises or crash
609        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
610        - EG fine tuning: when attack is zero the EG starts at a level
611          above max sustain level, which means that there is a decay phase
612          even if sustain is 100%
613        - more EG fixes: the level could sometimes go below zero and cause
614          noises or crashes
615        - minor fix of EGDecay (patch by Toshi Nagata)
616        - fixed compiler error when --enable-override-filter-type was
617          supplied to the configure script (fixes #46)
618        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
619          instead of a fix value
620        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
621          127 (solo mode) only kill voices if the respective mode really
622          changed
623    
624      * LSCP server:
625        - fixed compile time error for old Bison versions
626          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
627        - parser now supports extended ASCII character set
628          (up to ASCII code 255, i.e. includes now umlauts and accents)
629        - filename arguments in LSCP commands now allow to use escape
630          sequences, that is directly literal as one of: \', \", \\, \n, \r,
631          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
632          code value like \xf2) (fixes bug #24)
633        - the following LSCP commands now also support escape sequences for at
634          least one of their text-based parameters (i.e. name, description):
635          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
636          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
637          "SET DB_INSTRUMENT_DIRECTORY NAME",
638          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
639          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
640          "FIND DB_INSTRUMENT_DIRECTORIES"
641        - returns verbose syntax errors (line and column where syntax error
642          occured, the unexpected character and the actually expected, possible
643          character(s), the latter only if less than 5 possibilities)
644        - made sure that LSCP syntax is not affected by gigedit locale
645          settings
646        - bugfix regarding strings parameter lists: all comma separated lists
647          of strings were treated as being one string containing commas
648          (fixes #57)
649    
650      * Bug fixes:
651        - fixed crash occurring on certain LSCP scripts (Bug 39)
652        - another thread safety fix for lscp "load engine" and "set
653          channel audio output device"
654        - fixed a crash which occurs when reassigning the same engine
655          on a sampler channel with connected MIDI device
656        - fixed a crash which occurs when changing the number of ports of a MIDI
657          device connected to a sampler channel to number less then or equal
658          to the index of the port to which the sampler channel is connected.
659        - The previous bindings were not been disconnected when altering
660          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
661          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
662        - The active stream/voice count statistic was incorrect.
663        - notification events were not been sent for some sampler
664          channel changes
665        - added default min and max values to restrict the number of allowed
666          audio output channels and MIDI input ports
667        - the connection to the PCM interface is now closed when destroying
668          an audio output device
669        - files with slash in their path or filename could not be loaded
670    
671      * test cases:
672        - updated and fixed (haven't been touched in a while)
673    
674    Version 0.4.0 (24 November 2006)
675    
676      * packaging changes:
677        - changed deprecated copyright attribute to license; added ldconfig
678          to post-(un)install steps; added devel package for liblinuxsampler;
679          to linuxsampler.spec (RPM)
680        - install necessary development header files for allowing 3rd party
681          applications to link against liblinuxsampler
682        - liblinuxsampler's API documentation can be generated with 'make docs'
683          (Doxygen required)
684        - added benchmark to automatically detect the best triangle LFO
685          implementation (currently either an integer math solution or a
686          di-harmonic approximation), automatic detection can be overriden
687          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
688          configure script argument though (mandatory for cross-compilation)
689        - do not automatically pick optimized gcc flags if the user already
690          provided some on his own (as CXXFLAGS)
691        - added compile time option to disable processing of All-Notes-Off MIDI
692          messages
693        - added compile time options to allow disabling the various audio and
694          MIDI drivers
695        - fixed automatic GCC CPU switch detection on PPC
696          (patch by Ebrahim Mayat)
697    
698      * Gigasampler format engine:
699        - extensive synthesis optimization
700          (reimplementation of EGs and LFO(s), removed synthesis parameter
701          prerendering and the synthesis parameter matrix in general, splitting
702          each audio fragment into subfragments now where each subfragment uses
703          constant pitch and filter coefficients. The volume coefficient is
704          linearly interpolated inside a subfragment, unless
705          --disable-interpolate-volume is set.)
706        - fine tuning of the EG modulation parameters
707        - improved filter cutoff calculation by adding support for the
708          following gig parameters: Cutoff freq (used when no cutoff
709          controller is defined), Control invert, Minimum cutoff, Velocity
710          curve and Velocity range. The keyboard tracking now scales
711          cutoff frequency instead of resonance.
712        - added support for gig parameter Resonance.
713        - fixed bug in sysex handling (patch by Juan Linietsky)
714        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
715          which can be overridden with --enable-global-attenuation
716        - EG fixes: made the length of "attack hold" stage more
717          accurate. Release stage can now start before attack stage
718          ends. Cancel release didn't work when sustain was zero. Attack
719          time now has a minimal value to prevent clicks.
720        - fixed pitch changes larger than one octave
721        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
722        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
723          all modes can be altered via standard GM messages, that is CC5 for
724          altering portamento time, CC65 for enabling / disabling portamento
725          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
726        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
727          parameter) and crossfade
728        - added support for the "attenuation controller threshold" gig
729          parameter
730        - added smoothing of volume changes caused by control change
731          messages
732        - sample loop parameters are now taken from the DimensionRegion
733          instead of the wave chunk
734        - fixed keyswitching for v3 gigs with a number of keyswitch splits
735          not equal to a power of two
736        - reimplementation of the filter algorithm. The new filter is more
737          accurate and supports all gig filter types, including bandreject
738          and lowpass turbo.
739        - real support for 24 bit samples - samples are not truncated to
740          16 bits anymore
741        - support for aftertouch (channel pressure, not polyphonic
742          aftertouch)
743        - LFO1 behaviour fixed (dampening from max volume instead of
744          amplifying from 0)
745    
746      * LSCP server:
747        - fixed application exit on broken pipe error (fixes bug #20)
748        - fixed the notification messages delay due to lack of
749          network activity (fixes bug #26)
750        - fixed parser bug which occured on space(s) within device parameters
751          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
752    
753      * audio driver:
754        - added aRts audio output driver (by no means RT safe)
755    
756      * MIDI driver:
757        - fixed legacy sysex code which caused dispatching of MIDI SysEx
758          messages several times instead of once
759        - API extension for MIDI drivers which already supply exact time stamps
760          for events (i.e. for offline rendering based MIDI drivers)
761        - added checks for bad MIDI data
762    
763      * linuxsampler application:
764        - show available sampler engine types on startup
765    
766      * general changes:
767        - support for muting sampler channels and solo mode of the same, two new
768          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
