1  Version CVS HEAD (?)  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    
9      * general changes:
10        - Refactoring: moved the independent code from
11          the Gigasampler format engine to base classes
12        - command line option '--profile' is currently disabled, since the
13          respective profiling code is currently broken
14        - Introduced support for optional environment variable
15          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16          where the sampler shall look for instrument editor plugins
17          (patch by Luis Garrido, slightly modified).
18        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21          note (in this implementation of the sampler its simply hard routed to
22          the 1st effect send of the sampler channel, no matter what the actual
23          effect type is)
24        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25          note (in this implementation of the sampler its simply hard routed to
26          the 2nd effect send of the sampler channel, no matter what the actual
27          effect type is)
28        - implemented support for internal LADSPA effects
29        - raised limit of program change queue from 100 to 512
30          (as suggested by Alex Stone)
31    
32      * Gigasampler format engine:
33        - implemented the "round robin keyboard" dimension
34        - fixed round robin and random dimensions for cases when number of
35          dimension zones is not a power of two
36        - made round robin use a counter for each region instead of each
37          key
38    
39      * SFZ format engine:
40        - Initial implementation (not usable yet)
41        - added support for v2 multiple stage envelope generators
42        - added a fine-tuned v1 envelope generator instead of using the
43          one from the gig engine
44        - fixed memory leak and memory handling errors
45        - added support for trigger=first, trigger=legato and sw_previous
46        - allow non-numerical key values ("C#4" for example)
47        - "key" opcode now sets pitch_keycenter too
48        - fixed error when unloading instrument with same sample used by
49          multiple regions
50        - added some opcode aliases, like loopmode for loop_mode, to be
51          more compatible
52        - added support for trigger=release and rt_decay
53        - added support for off_mode=normal
54        - added support for random, seq_position, seq_length and volume
55        - added v1 LFO opcodes to parser (no support in engine yet)
56        - added support for amp_veltrack and amp_velcurve_N
57        - fine-tuned the default velocity curve
58        - added support for transpose
59        - fixed crash when using sw_down/up
60        - improved logic for sw_lokey/hikey/up/down/last
61        - added more v1 aliases to parser
62        - reduced memory usage for sfz data
63        - RT-safeness: avoid malloc in audio thread
64        - fixed a bug that could cause voice stealing to fail
65        - optimized sample lookup
66        - improved support for exclusive groups (group, off_by and
67          off_mode)
68        - added support for controller triggered regions (on_locc/on_hicc)
69        - added support for loop_mode=one_shot
70        - fixed playback of 16 bit wav files on big endian CPUs
71        - added support for Ogg Vorbis sample files
72        - use loop markers from sample file if loop_start and loop_end are
73          not set in sfz file
74    
75      * SoundFont format engine:
76        - Initial implementation (not usable yet)
77        - RT-safeness: avoid malloc in audio thread
78        - fixed a bug that could cause voice stealing to fail
79    
80      * Host plugins:
81        - AU bugfix: failed to destroy its audio/MIDI devices
82        - Listen to all interfaces on Mac OS X (INADDR_ANY)
83        - VST bugfix: If the host called resume() before and after
84          changing sample rate or block size, the number of channels was
85          incorrectly set to two. This caused silence in Cubase 5.
86        - save engine type (gig, sfz or sf2) in plugin state
87        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
88          64 bit Windows
89    
90      * MIDI driver:
91        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
92          the ALSA sequencer client name
93        - removed limit of maximum amount of MIDI ports per MIDI device, since
94          there is no reason for this limit
95    
96      * LSCP server:
97        - added support for sending MIDI CC messages via LSCP command
98          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

111        - added LSCP command "SET EFFECT_INSTANCE_INPUT_CONTROL VALUE
112          <effect-instance> <input-control> <value>"
113        - added LSCP command "GET SEND_EFFECT_CHAINS <audio-device>"
114        - added LSCP command "LIST SEND_EFFECT_CHAINS <audio-device>"
115        - added LSCP command "ADD SEND_EFFECT_CHAIN <audio-device>"

117          "REMOVE SEND_EFFECT_CHAIN <audio-device> <effect-chain>"
118        - added LSCP command
119          "GET SEND_EFFECT_CHAIN INFO <audio-device> <effect-chain>"
120        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>

122        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
123          <effect-chain> <effect-chain-pos> <effect-instance>"
124        - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
125          <effect-chain> <chain-pos>"
126        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
127          <fx_send_id> <effect_chain> <chain_pos>"
128        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
129    
130      * Bug fixes:
131        - Fixed crash which may occur when MIDI key + transpose is out of range
132        - minor valgrind fixes
133        - fixed crash which occured when changing an already deployed sampler
134          channel to a different engine type
135        - fixed crash when deleting a sampler channel or changing engine
136          type while an instrument load was in progress
137        - bugfix: playing a note while changing the instrument could cause
138          a crash, or give "Handing back unknown region" error messages
139        - bugfix: calling SET VOICES (which Fantasia does on start and
140          refresh) could cause instruments to be unloaded
141    
142    Version 1.0.0 (31 July 2009)
143    
144      * packaging changes:
145        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
146          causing e.g. the libgig test to fail when
147          "./configure --disable-jack-driver" was used
148          (patch by Alexis Ballier)
149        - fixed compilation with gcc 4.3
150        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
151        - fixed configure so it detects x86_64 (#107)
152        - fixes for building with newer MinGW versions
153        - fix for building with bison 2.4 (#111)
154        - fixed building with libgig installed in a non-standard directory
155        - minor fix in configure for mmsystem.h detection on MinGW
156        - Windows: look for editor plugins and Fantasia using base
157          directory of liblinuxsampler dll (look in the same directory and one
158          directory above)
159        - configure script fix: removed unconditional use of SSE
160        - fixed building with sqlite installed in a non-standard directory
161        - when cross-compiling, don't try to create instruments.db
162        - fix for new mingw-w64 version, which has usleep
163    
164      * general changes:
165        - bugfix: on some POSIX systems instrument editor plugins refused to
166          load as we used a non-portable Linux specific struct field
167          (fixes bug #70, patch by Ronald Baljeu)
168        - fixed endless loop which occured when loading an instrument editor
169          plugin DLL on Windows systems failed
170        - fixed memory leaks that occurred when liblinuxsampler was unloaded
171        - optimized the SynchronizedConfig class so it doesn't wait
172          unnecessarily long after an update
173        - added support for notifying instrument editors on note-on / note-off
174          events (e.g. to highlight the pressed keys on the virtual keyboard
175          of gigedit)
176        - added support for triggering notes by instrument editors (see above)
177        - be verbose on DLL load errors (on Linux)
178        - fixed di-harmonic triangle LFO implementation (this LFO implementation
179          is only used by very few systems, most pick the int math
180          implementation, which is usually faster)
181        - fixes for audio drivers with varying buffer sizes
182        - experimental support for running LinuxSampler as a DSSI, LV2 and
183          VST plugin
184        - notification events for stream/voice count statistics are now sent
185          only when there are actual changes
186        - added memory ordering constraints to improve stability on
187          multi-core and multi-cpu systems
188        - maximum voices and disk streams can now be altered at runtime
189        - fixed CPU feature detection on x86_64 (maybe fixes #108)
190        - automatic stacktrace mechanism is now turned off by default and can
191          be switched on by command line option "--stacktrace" (the automatic
192          stacktrace mechanism seems to be broken on most systems at the moment)
193        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
194          a pointer to the launched InstrumentEditor object
195        - added optional 3rd party user data parameter for following
196          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
197          InstrumentEditor::Launch(),
198          InstrumentManager::LaunchInstrumentEditor()
199        - theoretical fix: made SynchronizedConfig follow C++0x memory
200          model more strictly
201        - fixes for using large audio device buffers
202        - Windows: add the installation directory to the DLL search path
203          when loading an editor plugin (solves problems with VST and
204          gigedit on systems with other GTK versions installed)
205    
206      * audio driver:
207        - removed the nonsense audio channel constraint (which was hard coded to
208          max. 100 audio channels) for most audio drivers
209        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
210          opposed to the LSCP specs
211        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
212          reflected the wrong value
213        - fixed a memory management bug in ASIO driver
214        - Makefile fix: JACK_CFLAGS wasn't used
215        - JACK: use jack_client_open instead of the deprecated
216          jack_client_new
217        - added (experimental) CoreAudio driver
218        - applied old fixes to the ASIO driver that were included in the
219          previous binary release but accidentally never committed to CVS
220          (fixes #117)
221        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
222          win64)
223        - VST: added support for sample rate and buffer size changes
224        - VST: close editor (Fantasia) when the VST is removed
225        - VST: avoid opening Fantasia more than once for each VST instance
226        - VST: export main function as "main" on Linux too (fix for
227          energyXT)
228        - VST: changed number of output channels from one stereo to 16
229          stereo
230        - added channel routing, fxsends and midi maps to the settings
231          stored in the plugin state
232        - performance optimization of AudioChannel::MixTo() and
233          AudioChannel::CopyTo() methods using GCC vector exensions
234          (if available)
235        - ASIO fixes: avoid initializing the device twice, avoid throwing
236          exception when getting parameters from a disconnected device
237    
238      * MIDI driver:
239        - added JACK MIDI driver
240        - dispatch bank select as ordinary CC as well, the user might seriously
241          want to (mis)use it for some purpose ("fixed" in all current MIDI
242          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
243        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
244          CoreMidi or AU
245        - fixed mingw-w64 compilation error in MME driver
246        - made program change handling in MIDI thread real-time safe by
247          moving the logic to a non-RT thread
248        - fixed minor memory leak in ALSA driver
249    
250      * instruments database:
251        - avoid time consuming samples scanning when adding instruments
252          to the instruments database
253        - added support for handling lost files in the instruments database
254        - Implemented option for adding instruments in separate directories
255          in the instruments database
256          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
257        - work-around for missing fnmatch function on Windows to make
258          instrument database compilable
259        - added instrument database support on Windows
260          works with both standalone mode and VST plugin.
261          the instruments DB file is located in
262          %USERPROFILE%\.linuxsampler\instruments.db which allows different
263          databases for each windows user
264          if no DB is present it automatically creates the .linuxsampler subdir
265          and then creates an empty DB
266        - fixed recursive import, which was broken on Windows
267    
268      * Gigasampler format engine:
269        - fixed a memory leak that could happen when a channel was deleted
270          while notes were playing
271        - made it possible to load an instrument even if the audio thread
272          isn't running
273        - added partial support for the "Controller Triggered" MIDI rule,
274          enough for piano gigs with pedal noise samples
275        - minor fix: only mark FX sends as being modified if really the
276          respective FX send MIDI controller was used
277        - added support for GM global device volume SysEx message
278          (can be selected at compile time to either apply globally to the
279          whole sampler [default] or only to the sampler channels that are
280          connected to the respective MIDI input port the SysEx message arrived
281          on)
282        - bugfix: notes triggered at position 0 in the audio buffer were
283          sometimes wrongly killed in the same buffer, causing no sound to
284          be played
285        - added support for chromatic / drumkit mode Roland GS Sysex message
286          which is usally used to switch a part between chromatic sounds and
287          drumkit sounds (as opposed to their common default setting of MIDI
288          part 10 being a drumkit part and all other ones chromatic parts), in
289          LS however one can switch between the first 16 MIDI instrument maps
290          defined for the sampler
291        - made it possible to create multiple sample channels even if the
292          audio thread isn't running
293        - fixed crash when removing channel with active voices (#116)
294        - bugfix: on sample reference changes (instrument editor), only
295          un-cache the respective sample if it's really not used by any
296          sampler engine anymore
297        - re-cache samples in case they were changed by an instrument editor,
298          e.g. when a sample was added while playing (#82)
299        - fixed hanging notes which occured when note-off event had the exact
300          same time stamp as the voice's note-on event and occured both in the
301          same audio fragment cycle (fixes bug #112)
302        - added support for the "fine tune" and "pitch bend range"
303          instrument-level gig parameters
304        - fixed minor artifacts in pitch bend handling
305        - added support for GS Reset SysEx message
306        - allow gig files to use unlimited downward pitch shifting
307        - added a limit check for upward pitch shifting
308        - bugfix: sometimes, when playing a note twice fast, the second
309          note was silent
310        - fixed crash happening when a pitch bend event arrived at the
311          same time a new instrument was loading
312    
313      * LSCP server:
314        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
315          react on MIDI data arriving on certain sampler channels (so far only
316          Note-On and Note-Off events are sent via this LSCP event)
317        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
318          react on MIDI data arriving on certain MIDI input devices (so far only
319          Note-On and Note-Off events are sent via this LSCP event)
320        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
321          SET DB_INSTRUMENT FILE_PATH
322        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
323          frontends to send MIDI messages to specific sampler channel
324        - added two additional fields to GET FILE INSTRUMENT INFO command -
325          KEY_BINDINGS and KEYSWITCH_BINDINGS
326        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
327          was incorrect
328        - Optimized the retrieval of the MIDI instrument mappings
329        - added new LSCP command "SET VOICES" to globally alter the maximum
330          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
331          be triggered respectively
332        - added new LSCP command "SET STREAMS" to globally alter the maximum
333          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
334          which will be triggered respectively
335        - bugfix: retry if "select" returns EINTR (this fixes a crash when
336          a gigedit file dialog is opened)
337        - close all connections when LSCPServer is deleted
338        - hard close of all sockets on exit
339        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
340          driver
341    
342      * Bug fixes:
343        - fixed a crash which occurs when removing a sampler channel waiting
344          to start instrument loading after another channel
345        - fixed a crash which occurs when removing a sampler channel with
346          instrument loading in progress (bug #113)
347        - fixed termination caused by uncaught exception when adding MIDI
348          instrument with PERSISTENT load mode
349        - fixed possible iterator invalidations when resetting the sampler
350        - fixed memory leaks when issuing the following LSCP commands:
351          GET AUDIO_OUTPUT_DRIVER INFO
352          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
353          GET MIDI_INPUT_DRIVER INFO
354          GET MIDI_INPUT_DRIVER_PARAMETER INFO
355        - fixed possible compilation error when sqlite is not present
356        - fixed orphaned pointers when setting maximum voices limit (bug #118)
357        - fixed crash when changing the audio output device of a sampler
358          channel with loaded instrument and start playing notes
359        - fixed endless loop in Engine::SuspendAll() (bug #120)
360        - fixed a low-level atomic load function that was broken on 64-bit
361          PowerPC, which probably could cause crashes on that platform
362        - fixed a memory management error which could cause a crash when a
363          plugin was unloaded
364        - bugfix: two private structs had the same name, which could cause
365          problems if the linker chose the wrong constructor
366        - fixed low-level ConditionServer usage bug that caused lockups on
367          Windows
368    
369    
370    Version 0.5.1 (6 December 2007)
371    
372      * packaging changes:
373        - added autoconf checks for pthread library
374        - added autoconf check for pthread bug found on certain NPTL-enabled
375          glibc versions (see Gentoo bug report #194076)
376        - added autoconf checks for MS Windows
377    
378      * general changes:
379        - bugfix: the thread used by an editor plugin didn't die when the
380          editor closed
381        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
382          out all the space. operator--() did not apply size_mask after
383          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
384          order to avoid problems with the _NonVolatileReader functions.
385        - bugfix: Stream.h: added a missing divide by BytesPerSample in
386          GetWriteSpace(). Since this function is currently only used in
387          the stream's qsort() compare function, it didn't trigger any
388          bugs.
389        - Resampler.h, Synthesizer.h: cubic interpolation now works in
390          24bit mode too. Faster method to read 24bit words on little
391          endian machines (x86): replaced 3 byte reads + shifts with a 1
392          unaligned 32bit read and shift
393        - experimental support for MS Windows (MIDI input via MME, AUDIO
394          output via ASIO)
395        - made handling of SIGINT signal (Ctrl-C) a bit more robust
396        - support for monitoring the total number of active disk streams
397          (new LSCP commands: GET TOTAL_STREAM_COUNT,
398          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
399    
400      * AUDIO driver:
401        - added Windows ASIO low latency audio driver
402    
403      * MIDI driver:
404        - added MME Windows MIDI driver
405    
406      * LSCP server:
407        - added support for Windows style path / filenames, however with
408          forward slash path separators instead of backslash
409          (i.e. "C:/foo/bar.gig")
410        - allow naughty liblscp to send non-string device parameters within
411          apostrophes as well
412        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
413          "LIST FILE INSTRUMENTS <file>" and
414          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
415          about an arbitrary instrument file on the system where the sampler is
416          running on
417    
418    Version 0.5.0 (15 October 2007)
419    
420      * packaging changes:
421        - config.h is not going to be installed along with liblinuxsampler's
422          API header files anymore
423        - only the API relevant header (and source) files will be exported to
424          the Doxygen API documentation (explicitly listed in Doxyfile.in)
425        - added completely new XCode project files for Mac OSX which is now
426          capable to execute our autoconf environment, thus no need anymore
427          to maintain the compile time configuration file (osx/version.h) for
428          OSX manually (patch by Toshi Nagata)
429        - fixed buggy boolean --enable-foo / --disable-foo configure script
430          parameters
431        - global.h now only covers global definitions that are needed for the
432          C++ API header files, all implementation internal global definitions
433          are now in global_private.h
434        - atomic.h is not exposed to the C++ API anymore
435        - no need to include config.h anymore for using LS's API header files
436        - fixed warnings in API doc generation
437

465        - Implemented new, improved notification system
466        - fixed compilation errors regarding OSX
467          (patch by Toshi Nagata)
468        - implemented instruments database
469        - added support for escape sequences to the instruments database
470        - added highly experimental support for on-the-fly instrument editing
471          within the sampler's process (by using instrument editor plugins),
472          you'll notice the new "Registered instrument editors:" message on
473          startup, added a new LSCP command:
474          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
475          to spawn a matching instrument editor for the instrument on the
476          given sampler channel, the plugin path can be overridden at compile
477          time with ./configure --enable-plugin-dir=/some/dir
478        - added experimental code for synchronizing instrument editors hosted
479          in the sampler's process to safely edit instruments while playing
480          without a crash (hopefully) by either suspending single regions
481          wherever possible or if unavoidable whole engine(s)
482        - fixed several issues in fundamental "Thread" class: set scheduling
483          policy and priority on thread level, set a minimum stack size for
484          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
485          threads simply inherited properties of starting thread instead of
486          setting their own policy and priority
487        - minor fix in our automatic stack trace mechanism on crashes, the
488          main process did not wait for the stack trace process to finish
489          its output
490        - fixed some minor memory leaks
491        - reenabled assembly features support, at the moment only for
492          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
493        - minor assembly fix in x86 features detection (don't use the PIC
494          register, to avoid relocations in the text segment at runtime)
495        - POSIX callback functions of Thread.h are hidden
496    
497    * MIDI driver:    * MIDI driver:
498      - dispatch bank select (MSB and LSB) messages      - dispatch bank select (MSB and LSB) messages

500      * audio driver:
501        - the ALSA audio output driver parameters now reflect the correct
502          parameter value ranges for the respective selected sound card
503          (patch by Till Wimmer, a bit fixed and extended)

515        - EG fine tuning: when attack is zero the EG starts at a level
516          above max sustain level, which means that there is a decay phase
517          even if sustain is 100%
518        - more EG fixes: the level could sometimes go below zero and cause
519          noises or crashes
520        - minor fix of EGDecay (patch by Toshi Nagata)
521        - fixed compiler error when --enable-override-filter-type was
522          supplied to the configure script (fixes #46)
523        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
524          instead of a fix value
525        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
526          127 (solo mode) only kill voices if the respective mode really
527          changed
528    
529      * LSCP server:
530        - fixed compile time error for old Bison versions
531          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
532        - parser now supports extended ASCII character set
533          (up to ASCII code 255, i.e. includes now umlauts and accents)
534        - filename arguments in LSCP commands now allow to use escape
535          sequences, that is directly literal as one of: \', \", \\, \n, \r,
536          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
537          code value like \xf2) (fixes bug #24)
538        - the following LSCP commands now also support escape sequences for at
539          least one of their text-based parameters (i.e. name, description):
540          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
541          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
542          "SET DB_INSTRUMENT_DIRECTORY NAME",
543          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
544          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
545          "FIND DB_INSTRUMENT_DIRECTORIES"
546        - returns verbose syntax errors (line and column where syntax error
547          occured, the unexpected character and the actually expected, possible
548          character(s), the latter only if less than 5 possibilities)
549        - made sure that LSCP syntax is not affected by gigedit locale
550          settings
551        - bugfix regarding strings parameter lists: all comma separated lists
552          of strings were treated as being one string containing commas
553          (fixes #57)
554    
555    * Bug fixes:    * Bug fixes:
556      - fixed crash occurring on certain LSCP scripts (Bug 39)      - fixed crash occurring on certain LSCP scripts (Bug 39)
557      - another thread safety fix for lscp "load engine" and "set      - another thread safety fix for lscp "load engine" and "set
558        channel audio output device"        channel audio output device"
559        - fixed a crash which occurs when reassigning the same engine
560          on a sampler channel with connected MIDI device
561        - fixed a crash which occurs when changing the number of ports of a MIDI
562          device connected to a sampler channel to number less then or equal
563          to the index of the port to which the sampler channel is connected.
564        - The previous bindings were not been disconnected when altering
565          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
566          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
567        - The active stream/voice count statistic was incorrect.
568        - notification events were not been sent for some sampler
569          channel changes
570        - added default min and max values to restrict the number of allowed
571          audio output channels and MIDI input ports
572        - the connection to the PCM interface is now closed when destroying
573          an audio output device
574        - files with slash in their path or filename could not be loaded
575    
576      * test cases:
577        - updated and fixed (haven't been touched in a while)
