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)

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

79        - optimized sample lookup
80        - improved support for exclusive groups (group, off_by and
81          off_mode)
82        - added support for controller triggered regions (on_locc/on_hicc)
83        - added support for loop_mode=one_shot

121        - initial implementation of cutoff filter
122    
123      * Gigasampler format engine:
124        - bugfix: pitch LFO controller "internal+aftertouch" was broken
125        - bugfix: filter keyboard tracking was broken
126        - filter performance fix (an unnecessary copy was made of the
127          filter parameters in each sub fragment)
128    
129      * Host plugins:
130        - AU bugfix: failed to destroy its audio/MIDI devices
131        - Listen to all interfaces on Mac OS X (INADDR_ANY)
132        - VST bugfix: If the host called resume() before and after
133          changing sample rate or block size, the number of channels was
134          incorrectly set to two. This caused silence in Cubase 5.
135        - save engine type (gig, sfz or sf2) in plugin state
136        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

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

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