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

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)

47        - implemented the "round robin keyboard" dimension
48        - fixed round robin and random dimensions for cases when number of
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

133        - AU bugfix: failed to destroy its audio/MIDI devices
134        - Listen to all interfaces on Mac OS X (INADDR_ANY)
135        - VST bugfix: If the host called resume() before and after
136          changing sample rate or block size, the number of channels was
137          incorrectly set to two. This caused silence in Cubase 5.
138        - save engine type (gig, sfz or sf2) in plugin state
139        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

148        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
149          the ALSA sequencer client name
150        - removed limit of maximum amount of MIDI ports per MIDI device, since
151          there is no reason for this limit
152    
153      * audio driver:
154        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
155

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