2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8        - Mac OS X: support the new dir for Core Audio SDK
9        - Mac OS X: fixed building outside source directory
10        - made sure all source files for hostplugins are included when
11          doing "make dist"
12        - removed empty directories left from the cvs to svn migration
13        - fixed compilation with gcc 4.6.1
14        - another "make dist" fix, for the LV2 plugin
15        - made --enable-pthread-testcancel default on Mac OS X
16        - minor Makefile fix for building lscpparser when build and source
17          directories are separate
18        - Mac OS X: made it possible to specify plugin installation dir to
19          configure
20        - Mac OS X: Makefile fix for the install-strip target
21    
22      * general changes:
23        - Refactoring: moved the independent code from
24          the Gigasampler format engine to base classes
25        - command line option '--profile' is currently disabled, since the
26          respective profiling code is currently broken
27        - Introduced support for optional environment variable
28          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29          where the sampler shall look for instrument editor plugins
30          (patch by Luis Garrido, slightly modified).
31        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34          note (in this implementation of the sampler its simply hard routed to
35          the 1st effect send of the sampler channel, no matter what the actual
36          effect type is)
37        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38          note (in this implementation of the sampler its simply hard routed to
39          the 2nd effect send of the sampler channel, no matter what the actual
40          effect type is)
41        - implemented support for internal LADSPA effects
42        - raised limit of program change queue from 100 to 512
43          (as suggested by Alex Stone)
44

47        - fixed round robin and random dimensions for cases when number of
48          dimension zones is not a power of two
49        - made round robin use a counter for each region instead of each
50          key
51    
52      * SFZ format engine:
53        - Initial implementation (not usable yet)
54        - added support for v2 multiple stage envelope generators
55        - added a fine-tuned v1 envelope generator instead of using the
56          one from the gig engine

61        - fixed error when unloading instrument with same sample used by
62          multiple regions
63        - added some opcode aliases, like loopmode for loop_mode, to be
64          more compatible

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

107        - initial implementation of cutoff filter
108    
109      * Gigasampler format engine:
110        - bugfix: pitch LFO controller "internal+aftertouch" was broken
111        - bugfix: filter keyboard tracking was broken
112        - filter performance fix (an unnecessary copy was made of the
113          filter parameters in each sub fragment)
114    
115      * Host plugins:
116        - AU bugfix: failed to destroy its audio/MIDI devices
117        - Listen to all interfaces on Mac OS X (INADDR_ANY)
118        - VST bugfix: If the host called resume() before and after
119          changing sample rate or block size, the number of channels was
120          incorrectly set to two. This caused silence in Cubase 5.
121        - save engine type (gig, sfz or sf2) in plugin state
122        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
123          64 bit Windows
124        - AU: changed number of output channels from one stereo to 16
125          stereo
126        - VST: made it possible to build the VST plugin for Mac
127        - AU: link AU plugin dynamically if --disable-shared isn't
128          specified

131        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
132          the ALSA sequencer client name
133        - removed limit of maximum amount of MIDI ports per MIDI device, since
134          there is no reason for this limit
135    
136      * audio driver:
137        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
138

163        - added LSCP command "APPEND SEND_EFFECT_CHAIN EFFECT <audio-device>
164          <effect-chain> <effect-instance>"
165        - added LSCP command "INSERT SEND_EFFECT_CHAIN EFFECT <audio-device>
166          <effect-chain> <effect-chain-pos> <effect-instance>"

175    
176      * Bug fixes:
177        - Fixed crash which may occur when MIDI key + transpose is out of range
178        - minor valgrind fixes
179        - fixed crash which occurred when changing an already deployed sampler
180          channel to a different engine type
181        - fixed crash when deleting a sampler channel or changing engine
182          type while an instrument load was in progress
183        - bugfix: playing a note while changing the instrument could cause
184          a crash, or give "Handing back unknown region" error messages
185        - bugfix: calling SET VOICES (which Fantasia does on start and
186          refresh) could cause instruments to be unloaded
187        - Mac OS X: fixed name collision of enum in EffectControl and
188          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
189        - Mac OS X: fixed hanging threads
190        - Windows: disabled the previous thread fix on non-Mac systems, as
191          it caused hanging threads on Windows
192        - Fixed possible crashes due to corrupted MIDI/audio device list
193          after MIDI/audio device creation failure
194    
195    Version 1.0.0 (31 July 2009)
196    
197      * packaging changes:
198        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
199          causing e.g. the libgig test to fail when
200          "./configure --disable-jack-driver" was used
201          (patch by Alexis Ballier)
202        - fixed compilation with gcc 4.3
203        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
204        - fixed configure so it detects x86_64 (#107)
205        - fixes for building with newer MinGW versions
206        - fix for building with bison 2.4 (#111)
207        - fixed building with libgig installed in a non-standard directory
208        - minor fix in configure for mmsystem.h detection on MinGW
209        - Windows: look for editor plugins and Fantasia using base
210          directory of liblinuxsampler dll (look in the same directory and one
211          directory above)
212        - configure script fix: removed unconditional use of SSE
213        - fixed building with sqlite installed in a non-standard directory
214        - when cross-compiling, don't try to create instruments.db
215        - fix for new mingw-w64 version, which has usleep
216    
217      * general changes:
218        - bugfix: on some POSIX systems instrument editor plugins refused to
219          load as we used a non-portable Linux specific struct field
220          (fixes bug #70, patch by Ronald Baljeu)
221        - fixed endless loop which occured when loading an instrument editor
222          plugin DLL on Windows systems failed
223        - fixed memory leaks that occurred when liblinuxsampler was unloaded
224        - optimized the SynchronizedConfig class so it doesn't wait
225          unnecessarily long after an update
226        - added support for notifying instrument editors on note-on / note-off
227          events (e.g. to highlight the pressed keys on the virtual keyboard
228          of gigedit)
229        - added support for triggering notes by instrument editors (see above)
230        - be verbose on DLL load errors (on Linux)
231        - fixed di-harmonic triangle LFO implementation (this LFO implementation
232          is only used by very few systems, most pick the int math
233          implementation, which is usually faster)
234        - fixes for audio drivers with varying buffer sizes
235        - experimental support for running LinuxSampler as a DSSI, LV2 and
236          VST plugin
237        - notification events for stream/voice count statistics are now sent
238          only when there are actual changes
239        - added memory ordering constraints to improve stability on
240          multi-core and multi-cpu systems
241        - maximum voices and disk streams can now be altered at runtime
242        - fixed CPU feature detection on x86_64 (maybe fixes #108)
243        - automatic stacktrace mechanism is now turned off by default and can
244          be switched on by command line option "--stacktrace" (the automatic
245          stacktrace mechanism seems to be broken on most systems at the moment)
246        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
247          a pointer to the launched InstrumentEditor object
248        - added optional 3rd party user data parameter for following
249          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
250          InstrumentEditor::Launch(),
251          InstrumentManager::LaunchInstrumentEditor()
252        - theoretical fix: made SynchronizedConfig follow C++0x memory
253          model more strictly
254        - fixes for using large audio device buffers
255        - Windows: add the installation directory to the DLL search path
256          when loading an editor plugin (solves problems with VST and
257          gigedit on systems with other GTK versions installed)
258    
259      * audio driver:
260        - removed the nonsense audio channel constraint (which was hard coded to
261          max. 100 audio channels) for most audio drivers
262        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
263          opposed to the LSCP specs
264        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
265          reflected the wrong value
266        - fixed a memory management bug in ASIO driver
267        - Makefile fix: JACK_CFLAGS wasn't used
268        - JACK: use jack_client_open instead of the deprecated
269          jack_client_new
270        - added (experimental) CoreAudio driver
271        - applied old fixes to the ASIO driver that were included in the
272          previous binary release but accidentally never committed to CVS
273          (fixes #117)
274        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
275          win64)
276        - VST: added support for sample rate and buffer size changes
277        - VST: close editor (Fantasia) when the VST is removed
278        - VST: avoid opening Fantasia more than once for each VST instance
279        - VST: export main function as "main" on Linux too (fix for
280          energyXT)
281        - VST: changed number of output channels from one stereo to 16
282          stereo
283        - added channel routing, fxsends and midi maps to the settings
284          stored in the plugin state
285        - performance optimization of AudioChannel::MixTo() and
286          AudioChannel::CopyTo() methods using GCC vector exensions
287          (if available)
288        - ASIO fixes: avoid initializing the device twice, avoid throwing
289          exception when getting parameters from a disconnected device
290    
291      * MIDI driver:
292        - added JACK MIDI driver
293        - dispatch bank select as ordinary CC as well, the user might seriously
294          want to (mis)use it for some purpose ("fixed" in all current MIDI
295          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
296        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
297          CoreMidi or AU
298        - fixed mingw-w64 compilation error in MME driver
299        - made program change handling in MIDI thread real-time safe by
300          moving the logic to a non-RT thread
301        - fixed minor memory leak in ALSA driver
302    
303      * instruments database:
304        - avoid time consuming samples scanning when adding instruments
305          to the instruments database
306        - added support for handling lost files in the instruments database
307        - Implemented option for adding instruments in separate directories
308          in the instruments database
309          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
310        - work-around for missing fnmatch function on Windows to make
311          instrument database compilable
312        - added instrument database support on Windows
313          works with both standalone mode and VST plugin.
314          the instruments DB file is located in
315          %USERPROFILE%\.linuxsampler\instruments.db which allows different
316          databases for each windows user
317          if no DB is present it automatically creates the .linuxsampler subdir
318          and then creates an empty DB
319        - fixed recursive import, which was broken on Windows
320    
321      * Gigasampler format engine:
322        - fixed a memory leak that could happen when a channel was deleted
323          while notes were playing
324        - made it possible to load an instrument even if the audio thread
325          isn't running
326        - added partial support for the "Controller Triggered" MIDI rule,
327          enough for piano gigs with pedal noise samples
328        - minor fix: only mark FX sends as being modified if really the
329          respective FX send MIDI controller was used
330        - added support for GM global device volume SysEx message
331          (can be selected at compile time to either apply globally to the
332          whole sampler [default] or only to the sampler channels that are
333          connected to the respective MIDI input port the SysEx message arrived
334          on)
335        - bugfix: notes triggered at position 0 in the audio buffer were
336          sometimes wrongly killed in the same buffer, causing no sound to
337          be played
338        - added support for chromatic / drumkit mode Roland GS Sysex message
339          which is usally used to switch a part between chromatic sounds and
340          drumkit sounds (as opposed to their common default setting of MIDI
341          part 10 being a drumkit part and all other ones chromatic parts), in
342          LS however one can switch between the first 16 MIDI instrument maps
343          defined for the sampler
344        - made it possible to create multiple sample channels even if the
345          audio thread isn't running
346        - fixed crash when removing channel with active voices (#116)
347        - bugfix: on sample reference changes (instrument editor), only
348          un-cache the respective sample if it's really not used by any
349          sampler engine anymore
350        - re-cache samples in case they were changed by an instrument editor,
351          e.g. when a sample was added while playing (#82)
352        - fixed hanging notes which occured when note-off event had the exact
353          same time stamp as the voice's note-on event and occured both in the
354          same audio fragment cycle (fixes bug #112)
355        - added support for the "fine tune" and "pitch bend range"
356          instrument-level gig parameters
357        - fixed minor artifacts in pitch bend handling
358        - added support for GS Reset SysEx message
359        - allow gig files to use unlimited downward pitch shifting
360        - added a limit check for upward pitch shifting
361        - bugfix: sometimes, when playing a note twice fast, the second
362          note was silent
363        - fixed crash happening when a pitch bend event arrived at the
364          same time a new instrument was loading
365    
366      * LSCP server:
367        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
368          react on MIDI data arriving on certain sampler channels (so far only
369          Note-On and Note-Off events are sent via this LSCP event)
370        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
371          react on MIDI data arriving on certain MIDI input devices (so far only
372          Note-On and Note-Off events are sent via this LSCP event)
373        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
374          SET DB_INSTRUMENT FILE_PATH
375        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
376          frontends to send MIDI messages to specific sampler channel
377        - added two additional fields to GET FILE INSTRUMENT INFO command -
378          KEY_BINDINGS and KEYSWITCH_BINDINGS
379        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
380          was incorrect
381        - Optimized the retrieval of the MIDI instrument mappings
382        - added new LSCP command "SET VOICES" to globally alter the maximum
383          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
384          be triggered respectively
385        - added new LSCP command "SET STREAMS" to globally alter the maximum
386          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
387          which will be triggered respectively
388        - bugfix: retry if "select" returns EINTR (this fixes a crash when
389          a gigedit file dialog is opened)
390        - close all connections when LSCPServer is deleted
391        - hard close of all sockets on exit
392        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
393          driver
394    
395      * Bug fixes:
396        - fixed a crash which occurs when removing a sampler channel waiting
397          to start instrument loading after another channel
398        - fixed a crash which occurs when removing a sampler channel with
399          instrument loading in progress (bug #113)
400        - fixed termination caused by uncaught exception when adding MIDI
401          instrument with PERSISTENT load mode
402        - fixed possible iterator invalidations when resetting the sampler
403        - fixed memory leaks when issuing the following LSCP commands:
404          GET AUDIO_OUTPUT_DRIVER INFO
405          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
406          GET MIDI_INPUT_DRIVER INFO
407          GET MIDI_INPUT_DRIVER_PARAMETER INFO
408        - fixed possible compilation error when sqlite is not present
409        - fixed orphaned pointers when setting maximum voices limit (bug #118)
410        - fixed crash when changing the audio output device of a sampler
411          channel with loaded instrument and start playing notes
412        - fixed endless loop in Engine::SuspendAll() (bug #120)
413        - fixed a low-level atomic load function that was broken on 64-bit
414          PowerPC, which probably could cause crashes on that platform
415        - fixed a memory management error which could cause a crash when a
416          plugin was unloaded
417        - bugfix: two private structs had the same name, which could cause
418          problems if the linker chose the wrong constructor
419        - fixed low-level ConditionServer usage bug that caused lockups on
420          Windows
421    
422    
423    Version 0.5.1 (6 December 2007)
424    
425      * packaging changes:
426        - added autoconf checks for pthread library
427        - added autoconf check for pthread bug found on certain NPTL-enabled
428          glibc versions (see Gentoo bug report #194076)
429        - added autoconf checks for MS Windows
430    
431      * general changes:
432        - bugfix: the thread used by an editor plugin didn't die when the
433          editor closed
434        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
435          out all the space. operator--() did not apply size_mask after
436          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
437          order to avoid problems with the _NonVolatileReader functions.
438        - bugfix: Stream.h: added a missing divide by BytesPerSample in
439          GetWriteSpace(). Since this function is currently only used in
440          the stream's qsort() compare function, it didn't trigger any
441          bugs.
442        - Resampler.h, Synthesizer.h: cubic interpolation now works in
443          24bit mode too. Faster method to read 24bit words on little
444          endian machines (x86): replaced 3 byte reads + shifts with a 1
445          unaligned 32bit read and shift
446        - experimental support for MS Windows (MIDI input via MME, AUDIO
447          output via ASIO)
448        - made handling of SIGINT signal (Ctrl-C) a bit more robust
449        - support for monitoring the total number of active disk streams
450          (new LSCP commands: GET TOTAL_STREAM_COUNT,
451          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
452    
453      * AUDIO driver:
454        - added Windows ASIO low latency audio driver
455    
456      * MIDI driver:
457        - added MME Windows MIDI driver
458    
459      * LSCP server:
460        - added support for Windows style path / filenames, however with
461          forward slash path separators instead of backslash
462          (i.e. "C:/foo/bar.gig")
463        - allow naughty liblscp to send non-string device parameters within
464          apostrophes as well
465        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
466          "LIST FILE INSTRUMENTS <file>" and
467          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
468          about an arbitrary instrument file on the system where the sampler is
469          running on
470    
471    Version 0.5.0 (15 October 2007)
472    
473      * packaging changes:
474        - config.h is not going to be installed along with liblinuxsampler's
475          API header files anymore
476        - only the API relevant header (and source) files will be exported to
477          the Doxygen API documentation (explicitly listed in Doxyfile.in)
478        - added completely new XCode project files for Mac OSX which is now
479          capable to execute our autoconf environment, thus no need anymore
480          to maintain the compile time configuration file (osx/version.h) for
481          OSX manually (patch by Toshi Nagata)
482        - fixed buggy boolean --enable-foo / --disable-foo configure script
483          parameters
484        - global.h now only covers global definitions that are needed for the
485          C++ API header files, all implementation internal global definitions
486          are now in global_private.h
487        - atomic.h is not exposed to the C++ API anymore
488        - no need to include config.h anymore for using LS's API header files
489        - fixed warnings in API doc generation
490    
491      * general changes:
492        - replaced the old, confusing MIDI program change mechanism by a
493          flexible MIDI instrument mapper which allows to map arbitrary
494          (MIDI bank, MIDI program) pairs with arbitrary
495          (engine type, instrument file, file index) triplets which will be
496          loaded on the respective channel when such MIDI program change
497          messages arrive, beside that, each entry allows to define a life-time
498          strategy for the instrument, so the user can define whether the
499          instrument should i.e. be permanently loaded (to be able to switch
500          quickly among sounds) or i.e. loaded just on demand when the
501          respective program change arrives (to safe RAM space), as well as a
502          global volume factor for each entry, so the user can adjust the volume
503          dynamic of his mapped instrument collection without having to modify
504          the instrument files, also one can manage arbitrary amount of such
505          MIDI instrument maps and assign each sampler channel individually
506          a certain map, so that i.e. separation of normal instruments and
507          drumkits is possible
508        - new notification events for tracking changes to audio/MIDI devices,
509          MIDI instrument maps, MIDI instruments, FX sends, global volume.
510        - sampler was limited to load max. 200 instruments in the background
511          due to a constant size RingBuffer FIFO which is now replaced by a
512          dynamic (unlimited) size std::list FIFO
513        - added FX sends, these allow to route audio signals to arbitrary audio
514          output channels for being processed by external effect processors
515          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
516          controllers
517        - global (sampler wide) volume can now be controlled at runtime
518        - Implemented new, improved notification system
519        - fixed compilation errors regarding OSX
520          (patch by Toshi Nagata)
521        - implemented instruments database
522        - added support for escape sequences to the instruments database
523        - added highly experimental support for on-the-fly instrument editing
524          within the sampler's process (by using instrument editor plugins),
525          you'll notice the new "Registered instrument editors:" message on
526          startup, added a new LSCP command:
527          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
528          to spawn a matching instrument editor for the instrument on the
529          given sampler channel, the plugin path can be overridden at compile
530          time with ./configure --enable-plugin-dir=/some/dir
531        - added experimental code for synchronizing instrument editors hosted
532          in the sampler's process to safely edit instruments while playing
533          without a crash (hopefully) by either suspending single regions
534          wherever possible or if unavoidable whole engine(s)
535        - fixed several issues in fundamental "Thread" class: set scheduling
536          policy and priority on thread level, set a minimum stack size for
537          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
538          threads simply inherited properties of starting thread instead of
539          setting their own policy and priority
540        - minor fix in our automatic stack trace mechanism on crashes, the
541          main process did not wait for the stack trace process to finish
542          its output
543        - fixed some minor memory leaks
544        - reenabled assembly features support, at the moment only for
545          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
546        - minor assembly fix in x86 features detection (don't use the PIC
547          register, to avoid relocations in the text segment at runtime)
548        - POSIX callback functions of Thread.h are hidden
549    
550      * MIDI driver:
551        - dispatch bank select (MSB and LSB) messages
552    
553      * audio driver:
554        - the ALSA audio output driver parameters now reflect the correct
555          parameter value ranges for the respective selected sound card
556          (patch by Till Wimmer, a bit fixed and extended)
557    
558      * Gigasampler format engine:
559        - if a filter is used and EG2 finishes before EG1, let the voice
560          die when EG2 has finished (this fixes a problem with clicks and
561          voice starvation for some gigs)
562        - playback is no longer disabled during instrument loading
563        - all notes playing on a channel that changes its instrument keep
564          playing with the old instrument until they get a note off
565          command
566        - EG fix: a release value of zero could cause noises or crash
567        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
568        - EG fine tuning: when attack is zero the EG starts at a level
569          above max sustain level, which means that there is a decay phase
570          even if sustain is 100%
571        - more EG fixes: the level could sometimes go below zero and cause
572          noises or crashes
573        - minor fix of EGDecay (patch by Toshi Nagata)
574        - fixed compiler error when --enable-override-filter-type was
575          supplied to the configure script (fixes #46)
576        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
577          instead of a fix value
578        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
579          127 (solo mode) only kill voices if the respective mode really
580          changed
581    
582      * LSCP server:
583        - fixed compile time error for old Bison versions
584          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
585        - parser now supports extended ASCII character set
586          (up to ASCII code 255, i.e. includes now umlauts and accents)
587        - filename arguments in LSCP commands now allow to use escape
588          sequences, that is directly literal as one of: \', \", \\, \n, \r,
589          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
590          code value like \xf2) (fixes bug #24)
591        - the following LSCP commands now also support escape sequences for at
592          least one of their text-based parameters (i.e. name, description):
593          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
594          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
595          "SET DB_INSTRUMENT_DIRECTORY NAME",
596          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
597          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
598          "FIND DB_INSTRUMENT_DIRECTORIES"
599        - returns verbose syntax errors (line and column where syntax error
600          occured, the unexpected character and the actually expected, possible
601          character(s), the latter only if less than 5 possibilities)
602        - made sure that LSCP syntax is not affected by gigedit locale
603          settings
604        - bugfix regarding strings parameter lists: all comma separated lists
605          of strings were treated as being one string containing commas
606          (fixes #57)
607    
608      * Bug fixes:
609        - fixed crash occurring on certain LSCP scripts (Bug 39)
610        - another thread safety fix for lscp "load engine" and "set
611          channel audio output device"
612        - fixed a crash which occurs when reassigning the same engine
613          on a sampler channel with connected MIDI device
614        - fixed a crash which occurs when changing the number of ports of a MIDI
615          device connected to a sampler channel to number less then or equal
616          to the index of the port to which the sampler channel is connected.
617        - The previous bindings were not been disconnected when altering
618          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
619          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
620        - The active stream/voice count statistic was incorrect.
621        - notification events were not been sent for some sampler
622          channel changes
623        - added default min and max values to restrict the number of allowed
624          audio output channels and MIDI input ports
625        - the connection to the PCM interface is now closed when destroying
626          an audio output device
627        - files with slash in their path or filename could not be loaded
628    
629      * test cases:
630        - updated and fixed (haven't been touched in a while)
