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)
44

46        - implemented the "round robin keyboard" dimension
47        - fixed round robin and random dimensions for cases when number of
48          dimension zones is not a power of two
49        - made round robin use a counter for each region instead of each
50          key
51    
52      * SFZ format engine:
53        - Initial implementation (not usable yet)
54        - added support for v2 multiple stage envelope generators
55        - added a fine-tuned v1 envelope generator instead of using the
56          one from the gig engine
57        - fixed memory leak and memory handling errors
58        - added support for trigger=first, trigger=legato and sw_previous
59        - allow non-numerical key values ("C#4" for example)
60        - "key" opcode now sets pitch_keycenter too
61        - fixed error when unloading instrument with same sample used by
62          multiple regions
63        - added some opcode aliases, like loopmode for loop_mode, to be
64          more compatible

66        - added support for off_mode=normal
67        - added support for random, seq_position, seq_length and volume
68        - added v1 LFO opcodes to parser (no support in engine yet)

73        - improved logic for sw_lokey/hikey/up/down/last
74        - added more v1 aliases to parser
75        - reduced memory usage for sfz data
76        - RT-safeness: avoid malloc in audio thread
77        - fixed a bug that could cause voice stealing to fail
78        - optimized sample lookup
79        - improved support for exclusive groups (group, off_by and
80          off_mode)
81        - added support for controller triggered regions (on_locc/on_hicc)
82        - added support for loop_mode=one_shot
83        - fixed playback of 16 bit wav files on big endian CPUs
84        - added support for Ogg Vorbis sample files
85        - use loop markers from sample file if loop_start and loop_end are
86          not set in sfz file
87        - implemeted filters. Filter types: lowpass, bandpass, bandreject
88          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
89          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,

91        - bugfix: zero ampeg_sustain didn't work
92        - added support for velocity effect on amplifier envelope time
93          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
94          ampeg_vel2release)
95        - added support for EG hold (ampeg_hold)
96

103        - initial implementation of cutoff filter
104    
105      * Gigasampler format engine:
106        - bugfix: pitch LFO controller "internal+aftertouch" was broken
107        - bugfix: filter keyboard tracking was broken
108        - filter performance fix (an unnecessary copy was made of the
109          filter parameters in each sub fragment)
110    
111      * Host plugins:
112        - AU bugfix: failed to destroy its audio/MIDI devices
113        - Listen to all interfaces on Mac OS X (INADDR_ANY)
114        - VST bugfix: If the host called resume() before and after
115          changing sample rate or block size, the number of channels was
116          incorrectly set to two. This caused silence in Cubase 5.
117        - save engine type (gig, sfz or sf2) in plugin state
118        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
119          64 bit Windows
120        - AU: changed number of output channels from one stereo to 16
121          stereo
122        - VST: made it possible to build the VST plugin for Mac
123        - AU: link AU plugin dynamically if --disable-shared isn't
124          specified
125    
126      * MIDI driver:
127        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
128          the ALSA sequencer client name
129        - removed limit of maximum amount of MIDI ports per MIDI device, since
130          there is no reason for this limit
131    
132      * audio driver:
133        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
134    
135      * LSCP server:
136        - added support for sending MIDI CC messages via LSCP command
137          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

171    
172      * Bug fixes:
173        - Fixed crash which may occur when MIDI key + transpose is out of range
174        - minor valgrind fixes
175        - fixed crash which occurred when changing an already deployed sampler
176          channel to a different engine type
177        - fixed crash when deleting a sampler channel or changing engine
178          type while an instrument load was in progress
179        - bugfix: playing a note while changing the instrument could cause
180          a crash, or give "Handing back unknown region" error messages
181        - bugfix: calling SET VOICES (which Fantasia does on start and
182          refresh) could cause instruments to be unloaded
183        - Mac OS X: fixed name collision of enum in EffectControl and
184          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
185        - Mac OS X: fixed hanging threads
186        - Windows: disabled the previous thread fix on non-Mac systems, as
187          it caused hanging threads on Windows
188        - Fixed possible crashes due to corrupted MIDI/audio device list
189          after MIDI/audio device creation failure
190    
191    Version 1.0.0 (31 July 2009)
192    
193      * packaging changes:
194        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
195          causing e.g. the libgig test to fail when
196          "./configure --disable-jack-driver" was used
197          (patch by Alexis Ballier)
198        - fixed compilation with gcc 4.3
199        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
200        - fixed configure so it detects x86_64 (#107)
201        - fixes for building with newer MinGW versions
202        - fix for building with bison 2.4 (#111)
203        - fixed building with libgig installed in a non-standard directory
204        - minor fix in configure for mmsystem.h detection on MinGW
205        - Windows: look for editor plugins and Fantasia using base
206          directory of liblinuxsampler dll (look in the same directory and one
207          directory above)
208        - configure script fix: removed unconditional use of SSE
209        - fixed building with sqlite installed in a non-standard directory
210        - when cross-compiling, don't try to create instruments.db
211        - fix for new mingw-w64 version, which has usleep
212    
213      * general changes:
214        - bugfix: on some POSIX systems instrument editor plugins refused to
215          load as we used a non-portable Linux specific struct field
216          (fixes bug #70, patch by Ronald Baljeu)
217        - fixed endless loop which occured when loading an instrument editor
218          plugin DLL on Windows systems failed
219        - fixed memory leaks that occurred when liblinuxsampler was unloaded
220        - optimized the SynchronizedConfig class so it doesn't wait
221          unnecessarily long after an update
222        - added support for notifying instrument editors on note-on / note-off
223          events (e.g. to highlight the pressed keys on the virtual keyboard
224          of gigedit)
225        - added support for triggering notes by instrument editors (see above)
226        - be verbose on DLL load errors (on Linux)
227        - fixed di-harmonic triangle LFO implementation (this LFO implementation
228          is only used by very few systems, most pick the int math
229          implementation, which is usually faster)
230        - fixes for audio drivers with varying buffer sizes
231        - experimental support for running LinuxSampler as a DSSI, LV2 and
232          VST plugin
233        - notification events for stream/voice count statistics are now sent
234          only when there are actual changes
235        - added memory ordering constraints to improve stability on
236          multi-core and multi-cpu systems
237        - maximum voices and disk streams can now be altered at runtime
238        - fixed CPU feature detection on x86_64 (maybe fixes #108)
239        - automatic stacktrace mechanism is now turned off by default and can
240          be switched on by command line option "--stacktrace" (the automatic
241          stacktrace mechanism seems to be broken on most systems at the moment)
242        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
243          a pointer to the launched InstrumentEditor object
244        - added optional 3rd party user data parameter for following
245          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
246          InstrumentEditor::Launch(),
247          InstrumentManager::LaunchInstrumentEditor()
248        - theoretical fix: made SynchronizedConfig follow C++0x memory
249          model more strictly
250        - fixes for using large audio device buffers
251        - Windows: add the installation directory to the DLL search path
252          when loading an editor plugin (solves problems with VST and
253          gigedit on systems with other GTK versions installed)
254    
255      * audio driver:
256        - removed the nonsense audio channel constraint (which was hard coded to
257          max. 100 audio channels) for most audio drivers
258        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
259          opposed to the LSCP specs
260        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
261          reflected the wrong value
262        - fixed a memory management bug in ASIO driver
263        - Makefile fix: JACK_CFLAGS wasn't used
264        - JACK: use jack_client_open instead of the deprecated
265          jack_client_new
266        - added (experimental) CoreAudio driver
267        - applied old fixes to the ASIO driver that were included in the
268          previous binary release but accidentally never committed to CVS
269          (fixes #117)
270        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
271          win64)
272        - VST: added support for sample rate and buffer size changes
273        - VST: close editor (Fantasia) when the VST is removed
274        - VST: avoid opening Fantasia more than once for each VST instance
275        - VST: export main function as "main" on Linux too (fix for
276          energyXT)
277        - VST: changed number of output channels from one stereo to 16
278          stereo
279        - added channel routing, fxsends and midi maps to the settings
280          stored in the plugin state
281        - performance optimization of AudioChannel::MixTo() and
282          AudioChannel::CopyTo() methods using GCC vector exensions
283          (if available)
284        - ASIO fixes: avoid initializing the device twice, avoid throwing
285          exception when getting parameters from a disconnected device
286    
287      * MIDI driver:
288        - added JACK MIDI driver
289        - dispatch bank select as ordinary CC as well, the user might seriously
290          want to (mis)use it for some purpose ("fixed" in all current MIDI
291          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
292        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
293          CoreMidi or AU
294        - fixed mingw-w64 compilation error in MME driver
295        - made program change handling in MIDI thread real-time safe by
296          moving the logic to a non-RT thread
297        - fixed minor memory leak in ALSA driver
298    
299      * instruments database:
300        - avoid time consuming samples scanning when adding instruments
301          to the instruments database
302        - added support for handling lost files in the instruments database
303        - Implemented option for adding instruments in separate directories
304          in the instruments database
305          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
306        - work-around for missing fnmatch function on Windows to make
307          instrument database compilable
308        - added instrument database support on Windows
309          works with both standalone mode and VST plugin.
310          the instruments DB file is located in
311          %USERPROFILE%\.linuxsampler\instruments.db which allows different
312          databases for each windows user
313          if no DB is present it automatically creates the .linuxsampler subdir
314          and then creates an empty DB
315        - fixed recursive import, which was broken on Windows
316    
317      * Gigasampler format engine:
318        - fixed a memory leak that could happen when a channel was deleted
319          while notes were playing
320        - made it possible to load an instrument even if the audio thread
321          isn't running
322        - added partial support for the "Controller Triggered" MIDI rule,
323          enough for piano gigs with pedal noise samples
324        - minor fix: only mark FX sends as being modified if really the
325          respective FX send MIDI controller was used
326        - added support for GM global device volume SysEx message
327          (can be selected at compile time to either apply globally to the
328          whole sampler [default] or only to the sampler channels that are
329          connected to the respective MIDI input port the SysEx message arrived
330          on)
331        - bugfix: notes triggered at position 0 in the audio buffer were
332          sometimes wrongly killed in the same buffer, causing no sound to
333          be played
334        - added support for chromatic / drumkit mode Roland GS Sysex message
335          which is usally used to switch a part between chromatic sounds and
336          drumkit sounds (as opposed to their common default setting of MIDI
337          part 10 being a drumkit part and all other ones chromatic parts), in
338          LS however one can switch between the first 16 MIDI instrument maps
339          defined for the sampler
340        - made it possible to create multiple sample channels even if the
341          audio thread isn't running
342        - fixed crash when removing channel with active voices (#116)
343        - bugfix: on sample reference changes (instrument editor), only
344          un-cache the respective sample if it's really not used by any
345          sampler engine anymore
346        - re-cache samples in case they were changed by an instrument editor,
347          e.g. when a sample was added while playing (#82)
348        - fixed hanging notes which occured when note-off event had the exact
349          same time stamp as the voice's note-on event and occured both in the
350          same audio fragment cycle (fixes bug #112)
351        - added support for the "fine tune" and "pitch bend range"
352          instrument-level gig parameters
353        - fixed minor artifacts in pitch bend handling
354        - added support for GS Reset SysEx message
355        - allow gig files to use unlimited downward pitch shifting
356        - added a limit check for upward pitch shifting
357        - bugfix: sometimes, when playing a note twice fast, the second
358          note was silent
359        - fixed crash happening when a pitch bend event arrived at the
360          same time a new instrument was loading
361    
362      * LSCP server:
363        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
364          react on MIDI data arriving on certain sampler channels (so far only
365          Note-On and Note-Off events are sent via this LSCP event)
366        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
367          react on MIDI data arriving on certain MIDI input devices (so far only
368          Note-On and Note-Off events are sent via this LSCP event)
369        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
370          SET DB_INSTRUMENT FILE_PATH
371        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
372          frontends to send MIDI messages to specific sampler channel
373        - added two additional fields to GET FILE INSTRUMENT INFO command -
374          KEY_BINDINGS and KEYSWITCH_BINDINGS
375        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
376          was incorrect
377        - Optimized the retrieval of the MIDI instrument mappings
378        - added new LSCP command "SET VOICES" to globally alter the maximum
379          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
380          be triggered respectively
381        - added new LSCP command "SET STREAMS" to globally alter the maximum
382          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
383          which will be triggered respectively
384        - bugfix: retry if "select" returns EINTR (this fixes a crash when
385          a gigedit file dialog is opened)
386        - close all connections when LSCPServer is deleted
387        - hard close of all sockets on exit
388        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
389          driver
390    
391      * Bug fixes:
392        - fixed a crash which occurs when removing a sampler channel waiting
393          to start instrument loading after another channel
394        - fixed a crash which occurs when removing a sampler channel with
395          instrument loading in progress (bug #113)
396        - fixed termination caused by uncaught exception when adding MIDI
397          instrument with PERSISTENT load mode
398        - fixed possible iterator invalidations when resetting the sampler
399        - fixed memory leaks when issuing the following LSCP commands:
400          GET AUDIO_OUTPUT_DRIVER INFO
401          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
402          GET MIDI_INPUT_DRIVER INFO
403          GET MIDI_INPUT_DRIVER_PARAMETER INFO
404        - fixed possible compilation error when sqlite is not present
405        - fixed orphaned pointers when setting maximum voices limit (bug #118)
406        - fixed crash when changing the audio output device of a sampler
407          channel with loaded instrument and start playing notes
408        - fixed endless loop in Engine::SuspendAll() (bug #120)
409        - fixed a low-level atomic load function that was broken on 64-bit
410          PowerPC, which probably could cause crashes on that platform
411        - fixed a memory management error which could cause a crash when a
412          plugin was unloaded
413        - bugfix: two private structs had the same name, which could cause
414          problems if the linker chose the wrong constructor
415        - fixed low-level ConditionServer usage bug that caused lockups on
416          Windows
417    
418    
419    Version 0.5.1 (6 December 2007)
420    
421      * packaging changes:
422        - added autoconf checks for pthread library
423        - added autoconf check for pthread bug found on certain NPTL-enabled
424          glibc versions (see Gentoo bug report #194076)
425        - added autoconf checks for MS Windows
426    
427      * general changes:
428        - bugfix: the thread used by an editor plugin didn't die when the
429          editor closed
430        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
431          out all the space. operator--() did not apply size_mask after
432          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
433          order to avoid problems with the _NonVolatileReader functions.
434        - bugfix: Stream.h: added a missing divide by BytesPerSample in
435          GetWriteSpace(). Since this function is currently only used in
436          the stream's qsort() compare function, it didn't trigger any
437          bugs.
438        - Resampler.h, Synthesizer.h: cubic interpolation now works in
439          24bit mode too. Faster method to read 24bit words on little
440          endian machines (x86): replaced 3 byte reads + shifts with a 1
441          unaligned 32bit read and shift
442        - experimental support for MS Windows (MIDI input via MME, AUDIO
443          output via ASIO)
444        - made handling of SIGINT signal (Ctrl-C) a bit more robust
445        - support for monitoring the total number of active disk streams
446          (new LSCP commands: GET TOTAL_STREAM_COUNT,
447          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
448    
449      * AUDIO driver:
450        - added Windows ASIO low latency audio driver
451    
452      * MIDI driver:
453        - added MME Windows MIDI driver
454    
455      * LSCP server:
456        - added support for Windows style path / filenames, however with
457          forward slash path separators instead of backslash
458          (i.e. "C:/foo/bar.gig")
459        - allow naughty liblscp to send non-string device parameters within
460          apostrophes as well
461        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
462          "LIST FILE INSTRUMENTS <file>" and
463          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
464          about an arbitrary instrument file on the system where the sampler is
465          running on
466    
467    Version 0.5.0 (15 October 2007)
468    
469      * packaging changes:
470        - config.h is not going to be installed along with liblinuxsampler's
471          API header files anymore
472        - only the API relevant header (and source) files will be exported to
473          the Doxygen API documentation (explicitly listed in Doxyfile.in)
474        - added completely new XCode project files for Mac OSX which is now
475          capable to execute our autoconf environment, thus no need anymore
476          to maintain the compile time configuration file (osx/version.h) for
477          OSX manually (patch by Toshi Nagata)
478        - fixed buggy boolean --enable-foo / --disable-foo configure script
479          parameters
480        - global.h now only covers global definitions that are needed for the
481          C++ API header files, all implementation internal global definitions
482          are now in global_private.h
483        - atomic.h is not exposed to the C++ API anymore
484        - no need to include config.h anymore for using LS's API header files
485        - fixed warnings in API doc generation
486

514        - Implemented new, improved notification system
515        - fixed compilation errors regarding OSX
516          (patch by Toshi Nagata)
517        - implemented instruments database
518        - added support for escape sequences to the instruments database
519        - added highly experimental support for on-the-fly instrument editing
520          within the sampler's process (by using instrument editor plugins),
521          you'll notice the new "Registered instrument editors:" message on
522          startup, added a new LSCP command:
523          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
524          to spawn a matching instrument editor for the instrument on the
525          given sampler channel, the plugin path can be overridden at compile
526          time with ./configure --enable-plugin-dir=/some/dir
527        - added experimental code for synchronizing instrument editors hosted
528          in the sampler's process to safely edit instruments while playing
529          without a crash (hopefully) by either suspending single regions
530          wherever possible or if unavoidable whole engine(s)
531        - fixed several issues in fundamental "Thread" class: set scheduling
532          policy and priority on thread level, set a minimum stack size for
533          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
534          threads simply inherited properties of starting thread instead of
535          setting their own policy and priority
536        - minor fix in our automatic stack trace mechanism on crashes, the
537          main process did not wait for the stack trace process to finish
538          its output
539        - fixed some minor memory leaks
540        - reenabled assembly features support, at the moment only for
541          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
542        - minor assembly fix in x86 features detection (don't use the PIC
543          register, to avoid relocations in the text segment at runtime)
544        - POSIX callback functions of Thread.h are hidden
545

569        - minor fix of EGDecay (patch by Toshi Nagata)
570        - fixed compiler error when --enable-override-filter-type was
571          supplied to the configure script (fixes #46)
572        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
573          instead of a fix value
574        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
575          127 (solo mode) only kill voices if the respective mode really
576          changed
577    
578      * LSCP server:
579        - fixed compile time error for old Bison versions
580          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
581        - parser now supports extended ASCII character set
582          (up to ASCII code 255, i.e. includes now umlauts and accents)
583        - filename arguments in LSCP commands now allow to use escape
584          sequences, that is directly literal as one of: \', \", \\, \n, \r,
585          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
586          code value like \xf2) (fixes bug #24)
587        - the following LSCP commands now also support escape sequences for at
588          least one of their text-based parameters (i.e. name, description):
589          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
590          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
591          "SET DB_INSTRUMENT_DIRECTORY NAME",
592          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
593          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
594          "FIND DB_INSTRUMENT_DIRECTORIES"
595        - returns verbose syntax errors (line and column where syntax error
596          occured, the unexpected character and the actually expected, possible
597          character(s), the latter only if less than 5 possibilities)
598        - made sure that LSCP syntax is not affected by gigedit locale
599          settings
600        - bugfix regarding strings parameter lists: all comma separated lists
601          of strings were treated as being one string containing commas
602          (fixes #57)

608        - fixed a crash which occurs when reassigning the same engine
609          on a sampler channel with connected MIDI device
610        - fixed a crash which occurs when changing the number of ports of a MIDI
611          device connected to a sampler channel to number less then or equal
612          to the index of the port to which the sampler channel is connected.
613        - The previous bindings were not been disconnected when altering
614          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
615          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
616        - The active stream/voice count statistic was incorrect.
617        - notification events were not been sent for some sampler
618          channel changes
619        - added default min and max values to restrict the number of allowed
620          audio output channels and MIDI input ports
621        - the connection to the PCM interface is now closed when destroying
622          an audio output device
623        - files with slash in their path or filename could not be loaded
