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)

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

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

161          the ALSA sequencer client name
162        - removed limit of maximum amount of MIDI ports per MIDI device, since
163          there is no reason for this limit
164    
165      * audio driver:
166        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
167

205      * Bug fixes:
206        - Fixed crash which may occur when MIDI key + transpose is out of range
207        - minor valgrind fixes
208        - fixed crash which occurred when changing an already deployed sampler
209          channel to a different engine type
210        - fixed crash when deleting a sampler channel or changing engine
211          type while an instrument load was in progress
212        - bugfix: playing a note while changing the instrument could cause
213          a crash, or give "Handing back unknown region" error messages
214        - bugfix: calling SET VOICES (which Fantasia does on start and
215          refresh) could cause instruments to be unloaded
216        - Mac OS X: fixed name collision of enum in EffectControl and
217          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
218        - Mac OS X: fixed hanging threads
219        - Windows: disabled the previous thread fix on non-Mac systems, as
220          it caused hanging threads on Windows
221        - Fixed possible crashes due to corrupted MIDI/audio device list
222          after MIDI/audio device creation failure
223    
224    Version 1.0.0 (31 July 2009)
225    
226      * packaging changes:
227        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
228          causing e.g. the libgig test to fail when
229          "./configure --disable-jack-driver" was used
230          (patch by Alexis Ballier)
231        - fixed compilation with gcc 4.3
232        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
233        - fixed configure so it detects x86_64 (#107)
234        - fixes for building with newer MinGW versions
235        - fix for building with bison 2.4 (#111)
236        - fixed building with libgig installed in a non-standard directory
237        - minor fix in configure for mmsystem.h detection on MinGW
238        - Windows: look for editor plugins and Fantasia using base
239          directory of liblinuxsampler dll (look in the same directory and one
240          directory above)
241        - configure script fix: removed unconditional use of SSE
242        - fixed building with sqlite installed in a non-standard directory
243        - when cross-compiling, don't try to create instruments.db
244        - fix for new mingw-w64 version, which has usleep
245    
246      * general changes:
247        - bugfix: on some POSIX systems instrument editor plugins refused to
248          load as we used a non-portable Linux specific struct field
249          (fixes bug #70, patch by Ronald Baljeu)
250        - fixed endless loop which occured when loading an instrument editor
251          plugin DLL on Windows systems failed
252        - fixed memory leaks that occurred when liblinuxsampler was unloaded
253        - optimized the SynchronizedConfig class so it doesn't wait
254          unnecessarily long after an update
255        - added support for notifying instrument editors on note-on / note-off
256          events (e.g. to highlight the pressed keys on the virtual keyboard
257          of gigedit)
258        - added support for triggering notes by instrument editors (see above)
259        - be verbose on DLL load errors (on Linux)
260        - fixed di-harmonic triangle LFO implementation (this LFO implementation
261          is only used by very few systems, most pick the int math
262          implementation, which is usually faster)
263        - fixes for audio drivers with varying buffer sizes
264        - experimental support for running LinuxSampler as a DSSI, LV2 and
265          VST plugin
266        - notification events for stream/voice count statistics are now sent
267          only when there are actual changes
268        - added memory ordering constraints to improve stability on
269          multi-core and multi-cpu systems
270        - maximum voices and disk streams can now be altered at runtime
271        - fixed CPU feature detection on x86_64 (maybe fixes #108)
272        - automatic stacktrace mechanism is now turned off by default and can
273          be switched on by command line option "--stacktrace" (the automatic
274          stacktrace mechanism seems to be broken on most systems at the moment)
275        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
276          a pointer to the launched InstrumentEditor object
277        - added optional 3rd party user data parameter for following
278          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
279          InstrumentEditor::Launch(),
280          InstrumentManager::LaunchInstrumentEditor()
281        - theoretical fix: made SynchronizedConfig follow C++0x memory
282          model more strictly
283        - fixes for using large audio device buffers
284        - Windows: add the installation directory to the DLL search path
285          when loading an editor plugin (solves problems with VST and
286          gigedit on systems with other GTK versions installed)
287    
288      * audio driver:
289        - removed the nonsense audio channel constraint (which was hard coded to
290          max. 100 audio channels) for most audio drivers
291        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
292          opposed to the LSCP specs
293        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
294          reflected the wrong value
295        - fixed a memory management bug in ASIO driver
296        - Makefile fix: JACK_CFLAGS wasn't used
297        - JACK: use jack_client_open instead of the deprecated
298          jack_client_new
299        - added (experimental) CoreAudio driver
300        - applied old fixes to the ASIO driver that were included in the
301          previous binary release but accidentally never committed to CVS
302          (fixes #117)
303        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
304          win64)
305        - VST: added support for sample rate and buffer size changes
306        - VST: close editor (Fantasia) when the VST is removed
307        - VST: avoid opening Fantasia more than once for each VST instance
308        - VST: export main function as "main" on Linux too (fix for
309          energyXT)
310        - VST: changed number of output channels from one stereo to 16
311          stereo
312        - added channel routing, fxsends and midi maps to the settings
313          stored in the plugin state
314        - performance optimization of AudioChannel::MixTo() and
315          AudioChannel::CopyTo() methods using GCC vector exensions
316          (if available)
317        - ASIO fixes: avoid initializing the device twice, avoid throwing
318          exception when getting parameters from a disconnected device
319    
320      * MIDI driver:
321        - added JACK MIDI driver
322        - dispatch bank select as ordinary CC as well, the user might seriously
323          want to (mis)use it for some purpose ("fixed" in all current MIDI
324          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
325        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
326          CoreMidi or AU
327        - fixed mingw-w64 compilation error in MME driver
328        - made program change handling in MIDI thread real-time safe by
329          moving the logic to a non-RT thread
330        - fixed minor memory leak in ALSA driver
331    
332      * instruments database:
333        - avoid time consuming samples scanning when adding instruments
334          to the instruments database
335        - added support for handling lost files in the instruments database
336        - Implemented option for adding instruments in separate directories
337          in the instruments database
338          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
339        - work-around for missing fnmatch function on Windows to make
340          instrument database compilable
341        - added instrument database support on Windows
342          works with both standalone mode and VST plugin.
343          the instruments DB file is located in
344          %USERPROFILE%\.linuxsampler\instruments.db which allows different
345          databases for each windows user
346          if no DB is present it automatically creates the .linuxsampler subdir
347          and then creates an empty DB
348        - fixed recursive import, which was broken on Windows
349    
350      * Gigasampler format engine:
351        - fixed a memory leak that could happen when a channel was deleted
352          while notes were playing
353        - made it possible to load an instrument even if the audio thread
354          isn't running
355        - added partial support for the "Controller Triggered" MIDI rule,
356          enough for piano gigs with pedal noise samples
357        - minor fix: only mark FX sends as being modified if really the
358          respective FX send MIDI controller was used
359        - added support for GM global device volume SysEx message
360          (can be selected at compile time to either apply globally to the
361          whole sampler [default] or only to the sampler channels that are
362          connected to the respective MIDI input port the SysEx message arrived
363          on)
364        - bugfix: notes triggered at position 0 in the audio buffer were
365          sometimes wrongly killed in the same buffer, causing no sound to
366          be played
367        - added support for chromatic / drumkit mode Roland GS Sysex message
368          which is usally used to switch a part between chromatic sounds and
369          drumkit sounds (as opposed to their common default setting of MIDI
370          part 10 being a drumkit part and all other ones chromatic parts), in
371          LS however one can switch between the first 16 MIDI instrument maps
372          defined for the sampler
373        - made it possible to create multiple sample channels even if the
374          audio thread isn't running
375        - fixed crash when removing channel with active voices (#116)
376        - bugfix: on sample reference changes (instrument editor), only
377          un-cache the respective sample if it's really not used by any
378          sampler engine anymore
379        - re-cache samples in case they were changed by an instrument editor,
380          e.g. when a sample was added while playing (#82)
381        - fixed hanging notes which occured when note-off event had the exact
382          same time stamp as the voice's note-on event and occured both in the
383          same audio fragment cycle (fixes bug #112)
384        - added support for the "fine tune" and "pitch bend range"
385          instrument-level gig parameters
386        - fixed minor artifacts in pitch bend handling
387        - added support for GS Reset SysEx message
388        - allow gig files to use unlimited downward pitch shifting
389        - added a limit check for upward pitch shifting
390        - bugfix: sometimes, when playing a note twice fast, the second
391          note was silent
392        - fixed crash happening when a pitch bend event arrived at the
393          same time a new instrument was loading
394    
395      * LSCP server:
396        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
397          react on MIDI data arriving on certain sampler channels (so far only
398          Note-On and Note-Off events are sent via this LSCP event)
399        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
400          react on MIDI data arriving on certain MIDI input devices (so far only
401          Note-On and Note-Off events are sent via this LSCP event)
402        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
403          SET DB_INSTRUMENT FILE_PATH
404        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
405          frontends to send MIDI messages to specific sampler channel
406        - added two additional fields to GET FILE INSTRUMENT INFO command -
407          KEY_BINDINGS and KEYSWITCH_BINDINGS
408        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
409          was incorrect
410        - Optimized the retrieval of the MIDI instrument mappings
411        - added new LSCP command "SET VOICES" to globally alter the maximum
412          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
413          be triggered respectively
414        - added new LSCP command "SET STREAMS" to globally alter the maximum
415          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
416          which will be triggered respectively
417        - bugfix: retry if "select" returns EINTR (this fixes a crash when
418          a gigedit file dialog is opened)
419        - close all connections when LSCPServer is deleted
420        - hard close of all sockets on exit
421        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
422          driver
423    
424      * Bug fixes:
425        - fixed a crash which occurs when removing a sampler channel waiting
426          to start instrument loading after another channel
427        - fixed a crash which occurs when removing a sampler channel with
428          instrument loading in progress (bug #113)
429        - fixed termination caused by uncaught exception when adding MIDI
430          instrument with PERSISTENT load mode
431        - fixed possible iterator invalidations when resetting the sampler
432        - fixed memory leaks when issuing the following LSCP commands:
433          GET AUDIO_OUTPUT_DRIVER INFO
434          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
435          GET MIDI_INPUT_DRIVER INFO
436          GET MIDI_INPUT_DRIVER_PARAMETER INFO
437        - fixed possible compilation error when sqlite is not present
438        - fixed orphaned pointers when setting maximum voices limit (bug #118)
439        - fixed crash when changing the audio output device of a sampler
440          channel with loaded instrument and start playing notes
441        - fixed endless loop in Engine::SuspendAll() (bug #120)
442        - fixed a low-level atomic load function that was broken on 64-bit
443          PowerPC, which probably could cause crashes on that platform
444        - fixed a memory management error which could cause a crash when a
445          plugin was unloaded
446        - bugfix: two private structs had the same name, which could cause
447          problems if the linker chose the wrong constructor
448        - fixed low-level ConditionServer usage bug that caused lockups on
449          Windows
450    
451    
452    Version 0.5.1 (6 December 2007)
453    
454      * packaging changes:
455        - added autoconf checks for pthread library
456        - added autoconf check for pthread bug found on certain NPTL-enabled
457          glibc versions (see Gentoo bug report #194076)
458        - added autoconf checks for MS Windows
459    
460      * general changes:
461        - bugfix: the thread used by an editor plugin didn't die when the
462          editor closed
463        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
464          out all the space. operator--() did not apply size_mask after
465          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
466          order to avoid problems with the _NonVolatileReader functions.
467        - bugfix: Stream.h: added a missing divide by BytesPerSample in
468          GetWriteSpace(). Since this function is currently only used in
469          the stream's qsort() compare function, it didn't trigger any
470          bugs.
471        - Resampler.h, Synthesizer.h: cubic interpolation now works in
472          24bit mode too. Faster method to read 24bit words on little
473          endian machines (x86): replaced 3 byte reads + shifts with a 1
474          unaligned 32bit read and shift
475        - experimental support for MS Windows (MIDI input via MME, AUDIO
476          output via ASIO)
477        - made handling of SIGINT signal (Ctrl-C) a bit more robust
478        - support for monitoring the total number of active disk streams
479          (new LSCP commands: GET TOTAL_STREAM_COUNT,
480          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
481    
482      * AUDIO driver:
483        - added Windows ASIO low latency audio driver
484    
485      * MIDI driver:
486        - added MME Windows MIDI driver
487    
488      * LSCP server:
489        - added support for Windows style path / filenames, however with
490          forward slash path separators instead of backslash
491          (i.e. "C:/foo/bar.gig")
492        - allow naughty liblscp to send non-string device parameters within
493          apostrophes as well
494        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
495          "LIST FILE INSTRUMENTS <file>" and
496          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
497          about an arbitrary instrument file on the system where the sampler is
498          running on
499    
500    Version 0.5.0 (15 October 2007)
501    
502      * packaging changes:
503        - config.h is not going to be installed along with liblinuxsampler's
504          API header files anymore
505        - only the API relevant header (and source) files will be exported to
506          the Doxygen API documentation (explicitly listed in Doxyfile.in)
507        - added completely new XCode project files for Mac OSX which is now
508          capable to execute our autoconf environment, thus no need anymore
509          to maintain the compile time configuration file (osx/version.h) for
510          OSX manually (patch by Toshi Nagata)
511        - fixed buggy boolean --enable-foo / --disable-foo configure script
512          parameters
513        - global.h now only covers global definitions that are needed for the
514          C++ API header files, all implementation internal global definitions
515          are now in global_private.h
516        - atomic.h is not exposed to the C++ API anymore
517        - no need to include config.h anymore for using LS's API header files
518        - fixed warnings in API doc generation
519    
520      * general changes:
521        - replaced the old, confusing MIDI program change mechanism by a
522          flexible MIDI instrument mapper which allows to map arbitrary
523          (MIDI bank, MIDI program) pairs with arbitrary
524          (engine type, instrument file, file index) triplets which will be
525          loaded on the respective channel when such MIDI program change
526          messages arrive, beside that, each entry allows to define a life-time
527          strategy for the instrument, so the user can define whether the
528          instrument should i.e. be permanently loaded (to be able to switch
529          quickly among sounds) or i.e. loaded just on demand when the
530          respective program change arrives (to safe RAM space), as well as a
531          global volume factor for each entry, so the user can adjust the volume
532          dynamic of his mapped instrument collection without having to modify
533          the instrument files, also one can manage arbitrary amount of such
534          MIDI instrument maps and assign each sampler channel individually
535          a certain map, so that i.e. separation of normal instruments and
536          drumkits is possible
537        - new notification events for tracking changes to audio/MIDI devices,
538          MIDI instrument maps, MIDI instruments, FX sends, global volume.
539        - sampler was limited to load max. 200 instruments in the background
540          due to a constant size RingBuffer FIFO which is now replaced by a
541          dynamic (unlimited) size std::list FIFO
542        - added FX sends, these allow to route audio signals to arbitrary audio
543          output channels for being processed by external effect processors
544          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
545          controllers
546        - global (sampler wide) volume can now be controlled at runtime
547        - Implemented new, improved notification system
548        - fixed compilation errors regarding OSX
549          (patch by Toshi Nagata)
550        - implemented instruments database
551        - added support for escape sequences to the instruments database
552        - added highly experimental support for on-the-fly instrument editing
553          within the sampler's process (by using instrument editor plugins),
554          you'll notice the new "Registered instrument editors:" message on
555          startup, added a new LSCP command:
556          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
557          to spawn a matching instrument editor for the instrument on the
558          given sampler channel, the plugin path can be overridden at compile
559          time with ./configure --enable-plugin-dir=/some/dir
560        - added experimental code for synchronizing instrument editors hosted
561          in the sampler's process to safely edit instruments while playing
562          without a crash (hopefully) by either suspending single regions
563          wherever possible or if unavoidable whole engine(s)
564        - fixed several issues in fundamental "Thread" class: set scheduling
565          policy and priority on thread level, set a minimum stack size for
566          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
567          threads simply inherited properties of starting thread instead of
568          setting their own policy and priority
569        - minor fix in our automatic stack trace mechanism on crashes, the
570          main process did not wait for the stack trace process to finish
571          its output
572        - fixed some minor memory leaks
573        - reenabled assembly features support, at the moment only for
574          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
575        - minor assembly fix in x86 features detection (don't use the PIC
576          register, to avoid relocations in the text segment at runtime)
577        - POSIX callback functions of Thread.h are hidden
578    
579      * MIDI driver:
580        - dispatch bank select (MSB and LSB) messages
581    
582      * audio driver:
583        - the ALSA audio output driver parameters now reflect the correct
584          parameter value ranges for the respective selected sound card
585          (patch by Till Wimmer, a bit fixed and extended)
586    
587      * Gigasampler format engine:
588        - if a filter is used and EG2 finishes before EG1, let the voice
589          die when EG2 has finished (this fixes a problem with clicks and
590          voice starvation for some gigs)
591        - playback is no longer disabled during instrument loading
592        - all notes playing on a channel that changes its instrument keep
593          playing with the old instrument until they get a note off
594          command
595        - EG fix: a release value of zero could cause noises or crash
596        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
597        - EG fine tuning: when attack is zero the EG starts at a level
598          above max sustain level, which means that there is a decay phase
599          even if sustain is 100%
600        - more EG fixes: the level could sometimes go below zero and cause
601          noises or crashes
602        - minor fix of EGDecay (patch by Toshi Nagata)
603        - fixed compiler error when --enable-override-filter-type was
604          supplied to the configure script (fixes #46)
605        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
606          instead of a fix value
607        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
608          127 (solo mode) only kill voices if the respective mode really
609          changed
610    
611      * LSCP server:
612        - fixed compile time error for old Bison versions
613          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
614        - parser now supports extended ASCII character set
615          (up to ASCII code 255, i.e. includes now umlauts and accents)
616        - filename arguments in LSCP commands now allow to use escape
617          sequences, that is directly literal as one of: \', \", \\, \n, \r,
618          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
619          code value like \xf2) (fixes bug #24)
620        - the following LSCP commands now also support escape sequences for at
621          least one of their text-based parameters (i.e. name, description):
622          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
623          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
624          "SET DB_INSTRUMENT_DIRECTORY NAME",
625          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
626          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
627          "FIND DB_INSTRUMENT_DIRECTORIES"
628        - returns verbose syntax errors (line and column where syntax error
629          occured, the unexpected character and the actually expected, possible
630          character(s), the latter only if less than 5 possibilities)
631        - made sure that LSCP syntax is not affected by gigedit locale
632          settings
633        - bugfix regarding strings parameter lists: all comma separated lists
634          of strings were treated as being one string containing commas
635          (fixes #57)
636    
637      * Bug fixes:
638        - fixed crash occurring on certain LSCP scripts (Bug 39)
639        - another thread safety fix for lscp "load engine" and "set
640          channel audio output device"
641        - fixed a crash which occurs when reassigning the same engine
642          on a sampler channel with connected MIDI device
643        - fixed a crash which occurs when changing the number of ports of a MIDI
644          device connected to a sampler channel to number less then or equal
645          to the index of the port to which the sampler channel is connected.
646        - The previous bindings were not been disconnected when altering
647          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
648          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
649        - The active stream/voice count statistic was incorrect.
650        - notification events were not been sent for some sampler
651          channel changes
652        - added default min and max values to restrict the number of allowed
653          audio output channels and MIDI input ports
654        - the connection to the PCM interface is now closed when destroying
655          an audio output device
656        - files with slash in their path or filename could not be loaded
657    
658      * test cases:
659        - updated and fixed (haven't been touched in a while)
660    
661    Version 0.4.0 (24 November 2006)
662    
663      * packaging changes:
664        - changed deprecated copyright attribute to license; added ldconfig
665          to post-(un)install steps; added devel package for liblinuxsampler;
666          to linuxsampler.spec (RPM)
667        - install necessary development header files for allowing 3rd party
668          applications to link against liblinuxsampler
669        - liblinuxsampler's API documentation can be generated with 'make docs'
670          (Doxygen required)
671        - added benchmark to automatically detect the best triangle LFO
672          implementation (currently either an integer math solution or a
673          di-harmonic approximation), automatic detection can be overriden
674          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
675          configure script argument though (mandatory for cross-compilation)
676        - do not automatically pick optimized gcc flags if the user already
677          provided some on his own (as CXXFLAGS)
678        - added compile time option to disable processing of All-Notes-Off MIDI
679          messages
680        - added compile time options to allow disabling the various audio and
681          MIDI drivers
682        - fixed automatic GCC CPU switch detection on PPC
683          (patch by Ebrahim Mayat)
684    
685      * Gigasampler format engine:
686        - extensive synthesis optimization
687          (reimplementation of EGs and LFO(s), removed synthesis parameter
688          prerendering and the synthesis parameter matrix in general, splitting
689          each audio fragment into subfragments now where each subfragment uses
690          constant pitch and filter coefficients. The volume coefficient is
691          linearly interpolated inside a subfragment, unless
692          --disable-interpolate-volume is set.)
693        - fine tuning of the EG modulation parameters
694        - improved filter cutoff calculation by adding support for the
695          following gig parameters: Cutoff freq (used when no cutoff
696          controller is defined), Control invert, Minimum cutoff, Velocity
697          curve and Velocity range. The keyboard tracking now scales
698          cutoff frequency instead of resonance.
699        - added support for gig parameter Resonance.
700        - fixed bug in sysex handling (patch by Juan Linietsky)
701        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
702          which can be overridden with --enable-global-attenuation
703        - EG fixes: made the length of "attack hold" stage more
704          accurate. Release stage can now start before attack stage
705          ends. Cancel release didn't work when sustain was zero. Attack
706          time now has a minimal value to prevent clicks.
707        - fixed pitch changes larger than one octave
708        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
709        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
710          all modes can be altered via standard GM messages, that is CC5 for
711          altering portamento time, CC65 for enabling / disabling portamento
712          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
713        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
714          parameter) and crossfade
715        - added support for the "attenuation controller threshold" gig
716          parameter
717        - added smoothing of volume changes caused by control change
718          messages
719        - sample loop parameters are now taken from the DimensionRegion
720          instead of the wave chunk
721        - fixed keyswitching for v3 gigs with a number of keyswitch splits
722          not equal to a power of two
723        - reimplementation of the filter algorithm. The new filter is more
724          accurate and supports all gig filter types, including bandreject
725          and lowpass turbo.
726        - real support for 24 bit samples - samples are not truncated to
727          16 bits anymore
728        - support for aftertouch (channel pressure, not polyphonic
729          aftertouch)
730        - LFO1 behaviour fixed (dampening from max volume instead of
731          amplifying from 0)
732    
733      * LSCP server:
734        - fixed application exit on broken pipe error (fixes bug #20)
735        - fixed the notification messages delay due to lack of
736          network activity (fixes bug #26)
737        - fixed parser bug which occured on space(s) within device parameters
738          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
739    
740      * audio driver:
741        - added aRts audio output driver (by no means RT safe)
742    
743      * MIDI driver:
744        - fixed legacy sysex code which caused dispatching of MIDI SysEx
745          messages several times instead of once
746        - API extension for MIDI drivers which already supply exact time stamps
747          for events (i.e. for offline rendering based MIDI drivers)
748        - added checks for bad MIDI data
749    
750      * linuxsampler application:
751        - show available sampler engine types on startup
752    
753      * general changes:
754        - support for muting sampler channels and solo mode of the same, two new
755          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
756          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
757          introduced for this, the behavior is the same like on a mixer console
758          (patch by Grigor Iliev, a bit adjusted). Also added configure option
759          --enable-process-muted-channels which can be used to enable the
760          processing of muted channels.
761        - support for sostenuto pedal
762        - support for monitoring the total number of active voices
763          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
764          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
765        - fixed some memory management errors
766        - fixed some concurrency problems that could lead to crashes when
767          LSCP commands were executed
768        - fixed crash when instrument loading failed previously on the same
769          sampler channel (fixes bug #36)
770    
771    Version 0.3.3 (15 July 2005)
772    
773      * packaging changes:
774        - fixed compilation with gcc 4.0
775    
776      * Gigasampler format engine:
777        - LFO preprocessing was performed even though the respective LFO was
778          disabled by the instrument patch (minor efficiency fix)
