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 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    
19      * general changes:
20        - Refactoring: moved the independent code from
21          the Gigasampler format engine to base classes
22        - command line option '--profile' is currently disabled, since the
23          respective profiling code is currently broken
24        - Introduced support for optional environment variable
25          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
26          where the sampler shall look for instrument editor plugins
27          (patch by Luis Garrido, slightly modified).
28        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
29        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
30        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
31          note (in this implementation of the sampler its simply hard routed to
32          the 1st effect send of the sampler channel, no matter what the actual
33          effect type is)
34        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
35          note (in this implementation of the sampler its simply hard routed to
36          the 2nd effect send of the sampler channel, no matter what the actual
37          effect type is)
38        - implemented support for internal LADSPA effects
39        - raised limit of program change queue from 100 to 512
40          (as suggested by Alex Stone)
41    
42      * Gigasampler format engine:

44        - fixed round robin and random dimensions for cases when number of
45          dimension zones is not a power of two
46        - made round robin use a counter for each region instead of each
47          key
48    
49      * SFZ format engine:
50        - Initial implementation (not usable yet)
51        - added support for v2 multiple stage envelope generators
52        - added a fine-tuned v1 envelope generator instead of using the
53          one from the gig engine
54        - fixed memory leak and memory handling errors
55        - added support for trigger=first, trigger=legato and sw_previous
56        - allow non-numerical key values ("C#4" for example)
57        - "key" opcode now sets pitch_keycenter too
58        - fixed error when unloading instrument with same sample used by
59          multiple regions
60        - added some opcode aliases, like loopmode for loop_mode, to be
61          more compatible
62        - added support for trigger=release and rt_decay
63        - added support for off_mode=normal
64        - added support for random, seq_position, seq_length and volume
65        - added v1 LFO opcodes to parser (no support in engine yet)
66        - added support for amp_veltrack and amp_velcurve_N
67        - fine-tuned the default velocity curve

71        - added more v1 aliases to parser
72        - reduced memory usage for sfz data
73        - RT-safeness: avoid malloc in audio thread
74        - fixed a bug that could cause voice stealing to fail
75        - optimized sample lookup
76        - improved support for exclusive groups (group, off_by and
77          off_mode)
78        - added support for controller triggered regions (on_locc/on_hicc)
79        - added support for loop_mode=one_shot
80        - fixed playback of 16 bit wav files on big endian CPUs
81        - added support for Ogg Vorbis sample files
82        - use loop markers from sample file if loop_start and loop_end are
83          not set in sfz file
84        - implemeted filters. Filter types: lowpass, bandpass, bandreject
85          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
86          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
87          cutoff_cc, cutoff_chanaft.
88        - bugfix: zero ampeg_sustain didn't work
89        - added support for velocity effect on amplifier envelope time
90          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
91          ampeg_vel2release)
92    
93      * SoundFont format engine:
94        - Initial implementation (not usable yet)
95        - RT-safeness: avoid malloc in audio thread
96        - fixed a bug that could cause voice stealing to fail
97

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

152        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
153          <effect-chain> <effect-instance>"
154        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
155          <effect-chain> <effect-chain-pos> <effect-instance>"

164    
165      * Bug fixes:
166        - Fixed crash which may occur when MIDI key + transpose is out of range
167        - minor valgrind fixes
168        - fixed crash which occured when changing an already deployed sampler
169          channel to a different engine type
170        - fixed crash when deleting a sampler channel or changing engine
171          type while an instrument load was in progress
172        - bugfix: playing a note while changing the instrument could cause
173          a crash, or give "Handing back unknown region" error messages
174        - bugfix: calling SET VOICES (which Fantasia does on start and
175          refresh) could cause instruments to be unloaded
176        - Mac OS X: fixed name collision of enum in EffectControl and
177          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
178        - Mac OS X: fixed hanging threads
179        - Windows: disabled the previous thread fix on non-Mac systems, as
180          it caused hanging threads on Windows
181    
182    Version 1.0.0 (31 July 2009)
183    
184      * packaging changes:
185        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
186          causing e.g. the libgig test to fail when
187          "./configure --disable-jack-driver" was used
188          (patch by Alexis Ballier)
189        - fixed compilation with gcc 4.3
190        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
191        - fixed configure so it detects x86_64 (#107)
192        - fixes for building with newer MinGW versions
193        - fix for building with bison 2.4 (#111)
194        - fixed building with libgig installed in a non-standard directory
195        - minor fix in configure for mmsystem.h detection on MinGW
196        - Windows: look for editor plugins and Fantasia using base
197          directory of liblinuxsampler dll (look in the same directory and one
198          directory above)
199        - configure script fix: removed unconditional use of SSE
200        - fixed building with sqlite installed in a non-standard directory
201        - when cross-compiling, don't try to create instruments.db
202        - fix for new mingw-w64 version, which has usleep
203    
204      * general changes:
205        - bugfix: on some POSIX systems instrument editor plugins refused to
206          load as we used a non-portable Linux specific struct field
207          (fixes bug #70, patch by Ronald Baljeu)
208        - fixed endless loop which occured when loading an instrument editor
209          plugin DLL on Windows systems failed
210        - fixed memory leaks that occurred when liblinuxsampler was unloaded
211        - optimized the SynchronizedConfig class so it doesn't wait
212          unnecessarily long after an update
213        - added support for notifying instrument editors on note-on / note-off
214          events (e.g. to highlight the pressed keys on the virtual keyboard
215          of gigedit)
216        - added support for triggering notes by instrument editors (see above)
217        - be verbose on DLL load errors (on Linux)
218        - fixed di-harmonic triangle LFO implementation (this LFO implementation
219          is only used by very few systems, most pick the int math
220          implementation, which is usually faster)
221        - fixes for audio drivers with varying buffer sizes
222        - experimental support for running LinuxSampler as a DSSI, LV2 and
223          VST plugin
224        - notification events for stream/voice count statistics are now sent
225          only when there are actual changes
226        - added memory ordering constraints to improve stability on
227          multi-core and multi-cpu systems
228        - maximum voices and disk streams can now be altered at runtime
229        - fixed CPU feature detection on x86_64 (maybe fixes #108)
230        - automatic stacktrace mechanism is now turned off by default and can
231          be switched on by command line option "--stacktrace" (the automatic
232          stacktrace mechanism seems to be broken on most systems at the moment)
233        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
234          a pointer to the launched InstrumentEditor object
235        - added optional 3rd party user data parameter for following
236          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
237          InstrumentEditor::Launch(),
238          InstrumentManager::LaunchInstrumentEditor()
239        - theoretical fix: made SynchronizedConfig follow C++0x memory
240          model more strictly
241        - fixes for using large audio device buffers
242        - Windows: add the installation directory to the DLL search path
243          when loading an editor plugin (solves problems with VST and
244          gigedit on systems with other GTK versions installed)
245    
246      * audio driver:
247        - removed the nonsense audio channel constraint (which was hard coded to
248          max. 100 audio channels) for most audio drivers
249        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
250          opposed to the LSCP specs
251        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
252          reflected the wrong value
253        - fixed a memory management bug in ASIO driver
254        - Makefile fix: JACK_CFLAGS wasn't used
255        - JACK: use jack_client_open instead of the deprecated
256          jack_client_new
257        - added (experimental) CoreAudio driver
258        - applied old fixes to the ASIO driver that were included in the
259          previous binary release but accidentally never committed to CVS
260          (fixes #117)
261        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
262          win64)
263        - VST: added support for sample rate and buffer size changes
264        - VST: close editor (Fantasia) when the VST is removed
265        - VST: avoid opening Fantasia more than once for each VST instance
266        - VST: export main function as "main" on Linux too (fix for
267          energyXT)
268        - VST: changed number of output channels from one stereo to 16
269          stereo
270        - added channel routing, fxsends and midi maps to the settings
271          stored in the plugin state
272        - performance optimization of AudioChannel::MixTo() and
273          AudioChannel::CopyTo() methods using GCC vector exensions
274          (if available)
275        - ASIO fixes: avoid initializing the device twice, avoid throwing
276          exception when getting parameters from a disconnected device
277    
278      * MIDI driver:
279        - added JACK MIDI driver
280        - dispatch bank select as ordinary CC as well, the user might seriously
281          want to (mis)use it for some purpose ("fixed" in all current MIDI
282          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
283        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
284          CoreMidi or AU
285        - fixed mingw-w64 compilation error in MME driver
286        - made program change handling in MIDI thread real-time safe by
287          moving the logic to a non-RT thread
288        - fixed minor memory leak in ALSA driver
289    
290      * instruments database:
291        - avoid time consuming samples scanning when adding instruments
292          to the instruments database
293        - added support for handling lost files in the instruments database
294        - Implemented option for adding instruments in separate directories
295          in the instruments database
296          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
297        - work-around for missing fnmatch function on Windows to make
298          instrument database compilable
299        - added instrument database support on Windows
300          works with both standalone mode and VST plugin.
301          the instruments DB file is located in
302          %USERPROFILE%\.linuxsampler\instruments.db which allows different
303          databases for each windows user
304          if no DB is present it automatically creates the .linuxsampler subdir
305          and then creates an empty DB
306        - fixed recursive import, which was broken on Windows
307    
308      * Gigasampler format engine:
309        - fixed a memory leak that could happen when a channel was deleted
310          while notes were playing
311        - made it possible to load an instrument even if the audio thread
312          isn't running
313        - added partial support for the "Controller Triggered" MIDI rule,
314          enough for piano gigs with pedal noise samples
315        - minor fix: only mark FX sends as being modified if really the
316          respective FX send MIDI controller was used
317        - added support for GM global device volume SysEx message
318          (can be selected at compile time to either apply globally to the
319          whole sampler [default] or only to the sampler channels that are
320          connected to the respective MIDI input port the SysEx message arrived
321          on)
322        - bugfix: notes triggered at position 0 in the audio buffer were
323          sometimes wrongly killed in the same buffer, causing no sound to
324          be played
325        - added support for chromatic / drumkit mode Roland GS Sysex message
326          which is usally used to switch a part between chromatic sounds and
327          drumkit sounds (as opposed to their common default setting of MIDI
328          part 10 being a drumkit part and all other ones chromatic parts), in
329          LS however one can switch between the first 16 MIDI instrument maps
330          defined for the sampler
331        - made it possible to create multiple sample channels even if the
332          audio thread isn't running
333        - fixed crash when removing channel with active voices (#116)
334        - bugfix: on sample reference changes (instrument editor), only
335          un-cache the respective sample if it's really not used by any
336          sampler engine anymore
337        - re-cache samples in case they were changed by an instrument editor,
338          e.g. when a sample was added while playing (#82)
339        - fixed hanging notes which occured when note-off event had the exact
340          same time stamp as the voice's note-on event and occured both in the
341          same audio fragment cycle (fixes bug #112)
342        - added support for the "fine tune" and "pitch bend range"
343          instrument-level gig parameters
344        - fixed minor artifacts in pitch bend handling
345        - added support for GS Reset SysEx message
346        - allow gig files to use unlimited downward pitch shifting
347        - added a limit check for upward pitch shifting
348        - bugfix: sometimes, when playing a note twice fast, the second
349          note was silent
350        - fixed crash happening when a pitch bend event arrived at the
351          same time a new instrument was loading
352    
353      * LSCP server:
354        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
355          react on MIDI data arriving on certain sampler channels (so far only
356          Note-On and Note-Off events are sent via this LSCP event)
357        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
358          react on MIDI data arriving on certain MIDI input devices (so far only
359          Note-On and Note-Off events are sent via this LSCP event)
360        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
361          SET DB_INSTRUMENT FILE_PATH
362        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
363          frontends to send MIDI messages to specific sampler channel
364        - added two additional fields to GET FILE INSTRUMENT INFO command -
365          KEY_BINDINGS and KEYSWITCH_BINDINGS
366        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
367          was incorrect
368        - Optimized the retrieval of the MIDI instrument mappings
369        - added new LSCP command "SET VOICES" to globally alter the maximum
370          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
371          be triggered respectively
372        - added new LSCP command "SET STREAMS" to globally alter the maximum
373          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
374          which will be triggered respectively
375        - bugfix: retry if "select" returns EINTR (this fixes a crash when
376          a gigedit file dialog is opened)
377        - close all connections when LSCPServer is deleted
378        - hard close of all sockets on exit
379        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
380          driver
381    
382      * Bug fixes:
383        - fixed a crash which occurs when removing a sampler channel waiting
384          to start instrument loading after another channel
385        - fixed a crash which occurs when removing a sampler channel with
386          instrument loading in progress (bug #113)
387        - fixed termination caused by uncaught exception when adding MIDI
388          instrument with PERSISTENT load mode
389        - fixed possible iterator invalidations when resetting the sampler
390        - fixed memory leaks when issuing the following LSCP commands:
391          GET AUDIO_OUTPUT_DRIVER INFO
392          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
393          GET MIDI_INPUT_DRIVER INFO
394          GET MIDI_INPUT_DRIVER_PARAMETER INFO
395        - fixed possible compilation error when sqlite is not present
396        - fixed orphaned pointers when setting maximum voices limit (bug #118)
397        - fixed crash when changing the audio output device of a sampler
398          channel with loaded instrument and start playing notes
399        - fixed endless loop in Engine::SuspendAll() (bug #120)
400        - fixed a low-level atomic load function that was broken on 64-bit
401          PowerPC, which probably could cause crashes on that platform
402        - fixed a memory management error which could cause a crash when a
403          plugin was unloaded
404        - bugfix: two private structs had the same name, which could cause
405          problems if the linker chose the wrong constructor
406        - fixed low-level ConditionServer usage bug that caused lockups on
407          Windows
408    
409    
410    Version 0.5.1 (6 December 2007)
411    
412      * packaging changes:
413        - added autoconf checks for pthread library
414        - added autoconf check for pthread bug found on certain NPTL-enabled
415          glibc versions (see Gentoo bug report #194076)
416        - added autoconf checks for MS Windows
417    
418      * general changes:
419        - bugfix: the thread used by an editor plugin didn't die when the
420          editor closed
421        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
422          out all the space. operator--() did not apply size_mask after
423          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
424          order to avoid problems with the _NonVolatileReader functions.
425        - bugfix: Stream.h: added a missing divide by BytesPerSample in
426          GetWriteSpace(). Since this function is currently only used in
427          the stream's qsort() compare function, it didn't trigger any
428          bugs.
429        - Resampler.h, Synthesizer.h: cubic interpolation now works in
430          24bit mode too. Faster method to read 24bit words on little
431          endian machines (x86): replaced 3 byte reads + shifts with a 1
432          unaligned 32bit read and shift
433        - experimental support for MS Windows (MIDI input via MME, AUDIO
434          output via ASIO)
435        - made handling of SIGINT signal (Ctrl-C) a bit more robust
436        - support for monitoring the total number of active disk streams
437          (new LSCP commands: GET TOTAL_STREAM_COUNT,
438          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
439    
440      * AUDIO driver:
441        - added Windows ASIO low latency audio driver
442    
443      * MIDI driver:
444        - added MME Windows MIDI driver
445    
446      * LSCP server:
447        - added support for Windows style path / filenames, however with
448          forward slash path separators instead of backslash
449          (i.e. "C:/foo/bar.gig")
450        - allow naughty liblscp to send non-string device parameters within
451          apostrophes as well
452        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
453          "LIST FILE INSTRUMENTS <file>" and
454          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
455          about an arbitrary instrument file on the system where the sampler is
456          running on
457    
458    Version 0.5.0 (15 October 2007)
459    
460      * packaging changes:
461        - config.h is not going to be installed along with liblinuxsampler's
462          API header files anymore
463        - only the API relevant header (and source) files will be exported to
464          the Doxygen API documentation (explicitly listed in Doxyfile.in)
465        - added completely new XCode project files for Mac OSX which is now
466          capable to execute our autoconf environment, thus no need anymore
467          to maintain the compile time configuration file (osx/version.h) for
468          OSX manually (patch by Toshi Nagata)
469        - fixed buggy boolean --enable-foo / --disable-foo configure script
470          parameters
471        - global.h now only covers global definitions that are needed for the
472          C++ API header files, all implementation internal global definitions
473          are now in global_private.h
474        - atomic.h is not exposed to the C++ API anymore
475        - no need to include config.h anymore for using LS's API header files
476        - fixed warnings in API doc generation
477

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

560        - minor fix of EGDecay (patch by Toshi Nagata)
561        - fixed compiler error when --enable-override-filter-type was
562          supplied to the configure script (fixes #46)
563        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
564          instead of a fix value
565        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
566          127 (solo mode) only kill voices if the respective mode really
567          changed
568    
569      * LSCP server:
570        - fixed compile time error for old Bison versions
571          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
572        - parser now supports extended ASCII character set
573          (up to ASCII code 255, i.e. includes now umlauts and accents)
574        - filename arguments in LSCP commands now allow to use escape
575          sequences, that is directly literal as one of: \', \", \\, \n, \r,
576          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
577          code value like \xf2) (fixes bug #24)
578        - the following LSCP commands now also support escape sequences for at
579          least one of their text-based parameters (i.e. name, description):
580          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
581          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
582          "SET DB_INSTRUMENT_DIRECTORY NAME",
583          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
584          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
585          "FIND DB_INSTRUMENT_DIRECTORIES"
586        - returns verbose syntax errors (line and column where syntax error
587          occured, the unexpected character and the actually expected, possible
588          character(s), the latter only if less than 5 possibilities)
589        - made sure that LSCP syntax is not affected by gigedit locale
590          settings
591        - bugfix regarding strings parameter lists: all comma separated lists
592          of strings were treated as being one string containing commas
593          (fixes #57)

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