2    
3    * packaging changes:    * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14    
15      * general changes:
16        - bugfix: on some POSIX systems instrument editor plugins refused to
17          load as we used a non-portable Linux specific struct field
18          (fixes bug #70, patch by Ronald Baljeu)
19        - fixed endless loop which occured when loading an instrument editor
20          plugin DLL on Windows systems failed
21        - fixed memory leaks that occurred when liblinuxsampler was unloaded
22        - optimized the SynchronizedConfig class so it doesn't wait
23          unnecessarily long after an update
24        - added support for notifying instrument editors on note-on / note-off
25          events (e.g. to highlight the pressed keys on the virtual keyboard
26          of gigedit)
27        - added support for triggering notes by instrument editors (see above)
28        - be verbose on DLL load errors (on Linux)
29        - fixed di-harmonic triangle LFO implementation (this LFO implementation
30          is only used by very few systems, most pick the int math
31          implementation, which is usually faster)
32        - fixes for audio drivers with varying buffer sizes
33        - experimental support for running LinuxSampler as a DSSI, LV2 and
34          VST plugin
35        - notification events for stream/voice count statistics are now sent
36          only when there are actual changes
37        - added memory ordering constraints to improve stability on
38          multi-core and multi-cpu systems
39        - maximum voices and disk streams can now be altered at runtime
40        - fixed CPU feature detection on x86_64 (maybe fixes #108)
41        - automatic stacktrace mechanism is now turned off by default and can
42          be switched on by command line option "--stacktrace" (the automatic
43          stacktrace mechanism seems to be broken on most systems at the moment)
44    
45      * audio driver:
46        - removed the nonsense audio channel constraint (which was hard coded to
47          max. 100 audio channels) for most audio drivers
48        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
49          opposed to the LSCP specs
50        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
51          reflected the wrong value
52        - fixed a memory management bug in ASIO driver
53        - Makefile fix: JACK_CFLAGS wasn't used
54        - JACK: use jack_client_open instead of the deprecated
55          jack_client_new
56        - added (experimental) CoreAudio driver
57    
58      * MIDI driver:
59        - added JACK MIDI driver
60        - dispatch bank select as ordinary CC as well, the user might seriously
61          want to (mis)use it for some purpose ("fixed" in all current MIDI
62          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
63    
64      * instruments database:
65        - avoid time consuming samples scanning when adding instruments
66          to the instruments database
67        - added support for handling lost files in the instruments database
68        - Implemented option for adding instruments in separate directories
69          in the instruments database
70          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
71    
72      * Gigasampler format engine:
73        - fixed a memory leak that could happen when a channel was deleted
74          while notes were playing
75        - made it possible to load an instrument even if the audio thread
76          isn't running
77        - added partial support for the "Controller Triggered" MIDI rule,
78          enough for piano gigs with pedal noise samples
79        - minor fix: only mark FX sends as being modified if really the
80          respective FX send MIDI controller was used
81        - added support for GM global device volume SysEx message
82          (can be selected at compile time to either apply globally to the
83          whole sampler [default] or only to the sampler channels that are
84          connected to the respective MIDI input port the SysEx message arrived
85          on)
86        - bugfix: notes triggered at position 0 in the audio buffer were
87          sometimes wrongly killed in the same buffer, causing no sound to
88          be played
89        - added support for chromatic / drumkit mode Roland GS Sysex message
90          which is usally used to switch a part between chromatic sounds and
91          drumkit sounds (as opposed to their common default setting of MIDI
92          part 10 being a drumkit part and all other ones chromatic parts), in
93          LS however one can switch between the first 16 MIDI instrument maps
94          defined for the sampler
95        - made it possible to create multiple sample channels even if the
96          audio thread isn't running
97        - fixed crash when removing channel with active voices (#116)
98        - bugfix: on sample reference changes (instrument editor), only
99          un-cache the respective sample if it's really not used by any
100          sampler engine anymore
101        - re-cache samples in case they were changed by an instrument editor,
102          e.g. when a sample was added while playing (#82)
103        - fixed hanging notes which occured when note-off event had the exact
104          same time stamp as the voice's note-on event and occured both in the
105          same audio fragment cycle (fixes bug #112)
106        - added support for the "fine tune" and "pitch bend range"
107          instrument-level gig parameters
108        - fixed minor artifacts in pitch bend handling
109    
110      * LSCP server:
111        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
112          react on MIDI data arriving on certain sampler channels (so far only
113          Note-On and Note-Off events are sent via this LSCP event)
114        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
115          react on MIDI data arriving on certain MIDI input devices (so far only
116          Note-On and Note-Off events are sent via this LSCP event)
117        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
118          SET DB_INSTRUMENT FILE_PATH
119        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
120          frontends to send MIDI messages to specific sampler channel
121        - added two additional fields to GET FILE INSTRUMENT INFO command -
122          KEY_BINDINGS and KEYSWITCH_BINDINGS
123        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
124          was incorrect
125        - Optimized the retrieval of the MIDI instrument mappings
126        - added new LSCP command "SET VOICES" to globally alter the maximum
127          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
128          be triggered respectively
129        - added new LSCP command "SET STREAMS" to globally alter the maximum
130          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
131          which will be triggered respectively
132        - bugfix: retry if "select" returns EINTR (this fixes a crash when
133          a gigedit file dialog is opened)
134        - close all connections when LSCPServer is deleted
135    
136      * Bug fixes:
137        - fixed a crash which occurs when removing a sampler channel waiting
138          to start instrument loading after another channel
139        - fixed a crash which occurs when removing a sampler channel with
140          instrument loading in progress (bug #113)
141        - fixed termination caused by uncaught exception when adding MIDI
142          instrument with PERSISTENT load mode
143        - fixed possible iterator invalidations when resetting the sampler
144        - fixed memory leaks when issuing the following LSCP commands:
145          GET AUDIO_OUTPUT_DRIVER INFO
146          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
147          GET MIDI_INPUT_DRIVER INFO
148          GET MIDI_INPUT_DRIVER_PARAMETER INFO
149        - fixed possible compilation error when sqlite is not present
150        - fixed orphaned pointers when setting maximum voices limit (bug #118)
151        - fixed crash when changing the audio output device of a sampler
152          channel with loaded instrument and start playing notes
153        - fixed endless loop in Engine::SuspendAll() (bug #120)
154    
155    
156    Version 0.5.1 (6 December 2007)
157    
158      * packaging changes:
159        - added autoconf checks for pthread library
160        - added autoconf check for pthread bug found on certain NPTL-enabled
161          glibc versions (see Gentoo bug report #194076)
162        - added autoconf checks for MS Windows
163    
164      * general changes:
165        - bugfix: the thread used by an editor plugin didn't die when the
166          editor closed
167        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
168          out all the space. operator--() did not apply size_mask after
169          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
170          order to avoid problems with the _NonVolatileReader functions.
171        - bugfix: Stream.h: added a missing divide by BytesPerSample in
172          GetWriteSpace(). Since this function is currently only used in
173          the stream's qsort() compare function, it didn't trigger any
174          bugs.
175        - Resampler.h, Synthesizer.h: cubic interpolation now works in
176          24bit mode too. Faster method to read 24bit words on little
177          endian machines (x86): replaced 3 byte reads + shifts with a 1
178          unaligned 32bit read and shift
179        - experimental support for MS Windows (MIDI input via MME, AUDIO
180          output via ASIO)
181        - made handling of SIGINT signal (Ctrl-C) a bit more robust
182        - support for monitoring the total number of active disk streams
183          (new LSCP commands: GET TOTAL_STREAM_COUNT,
184          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
185    
186      * AUDIO driver:
187        - added Windows ASIO low latency audio driver
188    
189      * MIDI driver:
190        - added MME Windows MIDI driver
191    
192      * LSCP server:
193        - added support for Windows style path / filenames, however with
194          forward slash path separators instead of backslash
195          (i.e. "C:/foo/bar.gig")
196        - allow naughty liblscp to send non-string device parameters within
197          apostrophes as well
198        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
199          "LIST FILE INSTRUMENTS <file>" and
200          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
201          about an arbitrary instrument file on the system where the sampler is
202          running on
203    
204    Version 0.5.0 (15 October 2007)
205    
206      * packaging changes:
207        - config.h is not going to be installed along with liblinuxsampler's
208          API header files anymore
209        - only the API relevant header (and source) files will be exported to
210          the Doxygen API documentation (explicitly listed in Doxyfile.in)
211        - added completely new XCode project files for Mac OSX which is now
212          capable to execute our autoconf environment, thus no need anymore
213          to maintain the compile time configuration file (osx/version.h) for
214          OSX manually (patch by Toshi Nagata)
215        - fixed buggy boolean --enable-foo / --disable-foo configure script
216          parameters
217        - global.h now only covers global definitions that are needed for the
218          C++ API header files, all implementation internal global definitions
219          are now in global_private.h
220        - atomic.h is not exposed to the C++ API anymore
221        - no need to include config.h anymore for using LS's API header files
222        - fixed warnings in API doc generation
223    
224      * general changes:
225        - replaced the old, confusing MIDI program change mechanism by a
226          flexible MIDI instrument mapper which allows to map arbitrary
227          (MIDI bank, MIDI program) pairs with arbitrary
228          (engine type, instrument file, file index) triplets which will be
229          loaded on the respective channel when such MIDI program change
230          messages arrive, beside that, each entry allows to define a life-time
231          strategy for the instrument, so the user can define whether the
232          instrument should i.e. be permanently loaded (to be able to switch
233          quickly among sounds) or i.e. loaded just on demand when the
234          respective program change arrives (to safe RAM space), as well as a
235          global volume factor for each entry, so the user can adjust the volume
236          dynamic of his mapped instrument collection without having to modify
237          the instrument files, also one can manage arbitrary amount of such
238          MIDI instrument maps and assign each sampler channel individually
239          a certain map, so that i.e. separation of normal instruments and
240          drumkits is possible
241        - new notification events for tracking changes to audio/MIDI devices,
242          MIDI instrument maps, MIDI instruments, FX sends, global volume.
243        - sampler was limited to load max. 200 instruments in the background
244          due to a constant size RingBuffer FIFO which is now replaced by a
245          dynamic (unlimited) size std::list FIFO
246        - added FX sends, these allow to route audio signals to arbitrary audio
247          output channels for being processed by external effect processors
248          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
249          controllers
250        - global (sampler wide) volume can now be controlled at runtime
251        - Implemented new, improved notification system
252        - fixed compilation errors regarding OSX
253          (patch by Toshi Nagata)
254        - implemented instruments database
255        - added support for escape sequences to the instruments database
256        - added highly experimental support for on-the-fly instrument editing
257          within the sampler's process (by using instrument editor plugins),
258          you'll notice the new "Registered instrument editors:" message on
259          startup, added a new LSCP command:
260          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
261          to spawn a matching instrument editor for the instrument on the
262          given sampler channel, the plugin path can be overridden at compile
263          time with ./configure --enable-plugin-dir=/some/dir
264        - added experimental code for synchronizing instrument editors hosted
265          in the sampler's process to safely edit instruments while playing
266          without a crash (hopefully) by either suspending single regions
267          wherever possible or if unavoidable whole engine(s)
268        - fixed several issues in fundamental "Thread" class: set scheduling
269          policy and priority on thread level, set a minimum stack size for
270          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
271          threads simply inherited properties of starting thread instead of
272          setting their own policy and priority
273        - minor fix in our automatic stack trace mechanism on crashes, the
274          main process did not wait for the stack trace process to finish
275          its output
276        - fixed some minor memory leaks
277        - reenabled assembly features support, at the moment only for
278          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
279        - minor assembly fix in x86 features detection (don't use the PIC
280          register, to avoid relocations in the text segment at runtime)
281        - POSIX callback functions of Thread.h are hidden
282    
283      * MIDI driver:
284        - dispatch bank select (MSB and LSB) messages
285    
286      * audio driver:
287        - the ALSA audio output driver parameters now reflect the correct
288          parameter value ranges for the respective selected sound card
289          (patch by Till Wimmer, a bit fixed and extended)
290    
291      * Gigasampler format engine:
292        - if a filter is used and EG2 finishes before EG1, let the voice
293          die when EG2 has finished (this fixes a problem with clicks and
294          voice starvation for some gigs)
295        - playback is no longer disabled during instrument loading
296        - all notes playing on a channel that changes its instrument keep
297          playing with the old instrument until they get a note off
298          command
299        - EG fix: a release value of zero could cause noises or crash
300        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
301        - EG fine tuning: when attack is zero the EG starts at a level
302          above max sustain level, which means that there is a decay phase
303          even if sustain is 100%
304        - more EG fixes: the level could sometimes go below zero and cause
305          noises or crashes
306        - minor fix of EGDecay (patch by Toshi Nagata)
307        - fixed compiler error when --enable-override-filter-type was
308          supplied to the configure script (fixes #46)
309        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
310          instead of a fix value
311        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
312          127 (solo mode) only kill voices if the respective mode really
313          changed
314    
315      * LSCP server:
316        - fixed compile time error for old Bison versions
317          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
318        - parser now supports extended ASCII character set
319          (up to ASCII code 255, i.e. includes now umlauts and accents)
320        - filename arguments in LSCP commands now allow to use escape
321          sequences, that is directly literal as one of: \', \", \\, \n, \r,
322          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
323          code value like \xf2) (fixes bug #24)
324        - the following LSCP commands now also support escape sequences for at
325          least one of their text-based parameters (i.e. name, description):
326          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
327          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
328          "SET DB_INSTRUMENT_DIRECTORY NAME",
329          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
330          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
331          "FIND DB_INSTRUMENT_DIRECTORIES"
332        - returns verbose syntax errors (line and column where syntax error
333          occured, the unexpected character and the actually expected, possible
334          character(s), the latter only if less than 5 possibilities)
335        - made sure that LSCP syntax is not affected by gigedit locale
336          settings
337        - bugfix regarding strings parameter lists: all comma separated lists
338          of strings were treated as being one string containing commas
339          (fixes #57)
340    
341      * Bug fixes:
342        - fixed crash occurring on certain LSCP scripts (Bug 39)
343        - another thread safety fix for lscp "load engine" and "set
344          channel audio output device"
345        - fixed a crash which occurs when reassigning the same engine
346          on a sampler channel with connected MIDI device
347        - fixed a crash which occurs when changing the number of ports of a MIDI
348          device connected to a sampler channel to number less then or equal
349          to the index of the port to which the sampler channel is connected.
350        - The previous bindings were not been disconnected when altering
351          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
352          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
353        - The active stream/voice count statistic was incorrect.
354        - notification events were not been sent for some sampler
355          channel changes
356        - added default min and max values to restrict the number of allowed
357          audio output channels and MIDI input ports
358        - the connection to the PCM interface is now closed when destroying
359          an audio output device
360        - files with slash in their path or filename could not be loaded
361    
362      * test cases:
363        - updated and fixed (haven't been touched in a while)
364    
365    Version 0.4.0 (24 November 2006)
366    
367      * packaging changes:
368        - changed deprecated copyright attribute to license; added ldconfig
369          to post-(un)install steps; added devel package for liblinuxsampler;
370          to linuxsampler.spec (RPM)
371        - install necessary development header files for allowing 3rd party
372          applications to link against liblinuxsampler
373        - liblinuxsampler's API documentation can be generated with 'make docs'
374          (Doxygen required)
375        - added benchmark to automatically detect the best triangle LFO
376          implementation (currently either an integer math solution or a
377          di-harmonic approximation), automatic detection can be overriden
378          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
379          configure script argument though (mandatory for cross-compilation)
380        - do not automatically pick optimized gcc flags if the user already
381          provided some on his own (as CXXFLAGS)
382        - added compile time option to disable processing of All-Notes-Off MIDI
383          messages
384        - added compile time options to allow disabling the various audio and
385          MIDI drivers
386        - fixed automatic GCC CPU switch detection on PPC
387          (patch by Ebrahim Mayat)
388    
389      * Gigasampler format engine:
390        - extensive synthesis optimization
391          (reimplementation of EGs and LFO(s), removed synthesis parameter
392          prerendering and the synthesis parameter matrix in general, splitting
393          each audio fragment into subfragments now where each subfragment uses
394          constant pitch and filter coefficients. The volume coefficient is
395          linearly interpolated inside a subfragment, unless
396          --disable-interpolate-volume is set.)
397        - fine tuning of the EG modulation parameters
398        - improved filter cutoff calculation by adding support for the
399          following gig parameters: Cutoff freq (used when no cutoff
400          controller is defined), Control invert, Minimum cutoff, Velocity
401          curve and Velocity range. The keyboard tracking now scales
402          cutoff frequency instead of resonance.
403        - added support for gig parameter Resonance.
404        - fixed bug in sysex handling (patch by Juan Linietsky)
405        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
406          which can be overridden with --enable-global-attenuation
407        - EG fixes: made the length of "attack hold" stage more
408          accurate. Release stage can now start before attack stage
409          ends. Cancel release didn't work when sustain was zero. Attack
410          time now has a minimal value to prevent clicks.
411        - fixed pitch changes larger than one octave
412        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
413        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
414          all modes can be altered via standard GM messages, that is CC5 for
415          altering portamento time, CC65 for enabling / disabling portamento
416          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
417        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
418          parameter) and crossfade
419        - added support for the "attenuation controller threshold" gig
420          parameter
421        - added smoothing of volume changes caused by control change
422          messages
423        - sample loop parameters are now taken from the DimensionRegion
424          instead of the wave chunk
425        - fixed keyswitching for v3 gigs with a number of keyswitch splits
426          not equal to a power of two
427        - reimplementation of the filter algorithm. The new filter is more
428          accurate and supports all gig filter types, including bandreject
429          and lowpass turbo.
430        - real support for 24 bit samples - samples are not truncated to
431          16 bits anymore
432        - support for aftertouch (channel pressure, not polyphonic
433          aftertouch)
434        - LFO1 behaviour fixed (dampening from max volume instead of
435          amplifying from 0)
436    
437      * LSCP server:
438        - fixed application exit on broken pipe error (fixes bug #20)
439        - fixed the notification messages delay due to lack of
440          network activity (fixes bug #26)
441        - fixed parser bug which occured on space(s) within device parameters
442          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
443    
444      * audio driver:
445        - added aRts audio output driver (by no means RT safe)
446    
447      * MIDI driver:
448        - fixed legacy sysex code which caused dispatching of MIDI SysEx
449          messages several times instead of once
450        - API extension for MIDI drivers which already supply exact time stamps
451          for events (i.e. for offline rendering based MIDI drivers)
452        - added checks for bad MIDI data
453    
454      * linuxsampler application:
455        - show available sampler engine types on startup
456    
457      * general changes:
458        - support for muting sampler channels and solo mode of the same, two new
459          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
460          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
461          introduced for this, the behavior is the same like on a mixer console
462          (patch by Grigor Iliev, a bit adjusted). Also added configure option
463          --enable-process-muted-channels which can be used to enable the
464          processing of muted channels.
465        - support for sostenuto pedal
466        - support for monitoring the total number of active voices
467          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
468          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
469        - fixed some memory management errors
470        - fixed some concurrency problems that could lead to crashes when
471          LSCP commands were executed
472        - fixed crash when instrument loading failed previously on the same
473          sampler channel (fixes bug #36)
474    
475    Version 0.3.3 (15 July 2005)
476    
477      * packaging changes:
478        - fixed compilation with gcc 4.0
479    
480      * Gigasampler format engine:
481        - LFO preprocessing was performed even though the respective LFO was
482          disabled by the instrument patch (minor efficiency fix)
483        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
484          for volume ramp downs in the same fragment (needed for current voice
485          stealing implementation) then simply inform the user with a warning
486          about possible click sounds and reduce the volume ramp down
487          appropriately instead of cancelling the audio device connection
488    
489    Version 0.3.2 (24 June 2005)
490    
491      * packaging changes:
492      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
493        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)

503      - volume of release triggered samples now depends on note-on velocity,      - volume of release triggered samples now depends on note-on velocity,
504        note length and gig parameter "release trigger decay" instead of        note length and gig parameter "release trigger decay" instead of

506      - revised voice stealing (fixes crash caused by voice stealing)      - revised voice stealing
507          (fixes crash and endless loop caused by voice stealing)
508        - don't reset scale tuning on instrument or audio output device change
509        - handle key group conflicts right at the beginning of each fragment
510          instead of when the respective voice is actually launched
511          (fixes undefined behavior if stolen voices belonged to a key group -
512          this case was followed by a "killed voice survived" error message)
513        - fixed minor issue with null/silence samples
514          (those stole voices even though they don't need a voice at all which
515          resulted in "voice stealing didn't work out" messages)
516        - don't reset volume, pan, pitch and MIDI controller values on
517          instrument or audio output device change

522          (e.g. did not notify on volume changes or MIDI program change events)
523    
524      * linuxsampler application:
525        - added command line parameters --lscp-addr and --lscp-port to override
526          default IP address and port of LSCP server
