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        - added support for GS Reset SysEx message
110    
111      * LSCP server:
112        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
113          react on MIDI data arriving on certain sampler channels (so far only
114          Note-On and Note-Off events are sent via this LSCP event)
115        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
116          react on MIDI data arriving on certain MIDI input devices (so far only
117          Note-On and Note-Off events are sent via this LSCP event)
118        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
119          SET DB_INSTRUMENT FILE_PATH
120        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
121          frontends to send MIDI messages to specific sampler channel
122        - added two additional fields to GET FILE INSTRUMENT INFO command -
123          KEY_BINDINGS and KEYSWITCH_BINDINGS
124        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
125          was incorrect
126        - Optimized the retrieval of the MIDI instrument mappings
127        - added new LSCP command "SET VOICES" to globally alter the maximum
128          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
129          be triggered respectively
130        - added new LSCP command "SET STREAMS" to globally alter the maximum
131          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
132          which will be triggered respectively
133        - bugfix: retry if "select" returns EINTR (this fixes a crash when
134          a gigedit file dialog is opened)
135        - close all connections when LSCPServer is deleted
136    
137      * Bug fixes:
138        - fixed a crash which occurs when removing a sampler channel waiting
139          to start instrument loading after another channel
140        - fixed a crash which occurs when removing a sampler channel with
141          instrument loading in progress (bug #113)
142        - fixed termination caused by uncaught exception when adding MIDI
143          instrument with PERSISTENT load mode
144        - fixed possible iterator invalidations when resetting the sampler
145        - fixed memory leaks when issuing the following LSCP commands:
146          GET AUDIO_OUTPUT_DRIVER INFO
147          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
148          GET MIDI_INPUT_DRIVER INFO
149          GET MIDI_INPUT_DRIVER_PARAMETER INFO
150        - fixed possible compilation error when sqlite is not present
151        - fixed orphaned pointers when setting maximum voices limit (bug #118)
152        - fixed crash when changing the audio output device of a sampler
153          channel with loaded instrument and start playing notes
154        - fixed endless loop in Engine::SuspendAll() (bug #120)
155    
156    
157    Version 0.5.1 (6 December 2007)
158    
159      * packaging changes:
160        - added autoconf checks for pthread library
161        - added autoconf check for pthread bug found on certain NPTL-enabled
162          glibc versions (see Gentoo bug report #194076)
163        - added autoconf checks for MS Windows
164    
165      * general changes:
166        - bugfix: the thread used by an editor plugin didn't die when the
167          editor closed
168        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
169          out all the space. operator--() did not apply size_mask after
170          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
171          order to avoid problems with the _NonVolatileReader functions.
172        - bugfix: Stream.h: added a missing divide by BytesPerSample in
173          GetWriteSpace(). Since this function is currently only used in
174          the stream's qsort() compare function, it didn't trigger any
175          bugs.
176        - Resampler.h, Synthesizer.h: cubic interpolation now works in
177          24bit mode too. Faster method to read 24bit words on little
178          endian machines (x86): replaced 3 byte reads + shifts with a 1
179          unaligned 32bit read and shift
180        - experimental support for MS Windows (MIDI input via MME, AUDIO
181          output via ASIO)
182        - made handling of SIGINT signal (Ctrl-C) a bit more robust
183        - support for monitoring the total number of active disk streams
184          (new LSCP commands: GET TOTAL_STREAM_COUNT,
185          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
186    
187      * AUDIO driver:
188        - added Windows ASIO low latency audio driver
189    
190      * MIDI driver:
191        - added MME Windows MIDI driver
192    
193      * LSCP server:
194        - added support for Windows style path / filenames, however with
195          forward slash path separators instead of backslash
196          (i.e. "C:/foo/bar.gig")
197        - allow naughty liblscp to send non-string device parameters within
198          apostrophes as well
199        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
200          "LIST FILE INSTRUMENTS <file>" and
201          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
202          about an arbitrary instrument file on the system where the sampler is
203          running on
204    
205    Version 0.5.0 (15 October 2007)
206    
207      * packaging changes:
208        - config.h is not going to be installed along with liblinuxsampler's
209          API header files anymore
210        - only the API relevant header (and source) files will be exported to
211          the Doxygen API documentation (explicitly listed in Doxyfile.in)
212        - added completely new XCode project files for Mac OSX which is now
213          capable to execute our autoconf environment, thus no need anymore
214          to maintain the compile time configuration file (osx/version.h) for
215          OSX manually (patch by Toshi Nagata)
216        - fixed buggy boolean --enable-foo / --disable-foo configure script
217          parameters
218        - global.h now only covers global definitions that are needed for the
219          C++ API header files, all implementation internal global definitions
220          are now in global_private.h
221        - atomic.h is not exposed to the C++ API anymore
222        - no need to include config.h anymore for using LS's API header files
223        - fixed warnings in API doc generation
224    
225      * general changes:
226        - replaced the old, confusing MIDI program change mechanism by a
227          flexible MIDI instrument mapper which allows to map arbitrary
228          (MIDI bank, MIDI program) pairs with arbitrary
229          (engine type, instrument file, file index) triplets which will be
230          loaded on the respective channel when such MIDI program change
231          messages arrive, beside that, each entry allows to define a life-time
232          strategy for the instrument, so the user can define whether the
233          instrument should i.e. be permanently loaded (to be able to switch
234          quickly among sounds) or i.e. loaded just on demand when the
235          respective program change arrives (to safe RAM space), as well as a
236          global volume factor for each entry, so the user can adjust the volume
237          dynamic of his mapped instrument collection without having to modify
238          the instrument files, also one can manage arbitrary amount of such
239          MIDI instrument maps and assign each sampler channel individually
240          a certain map, so that i.e. separation of normal instruments and
241          drumkits is possible
242        - new notification events for tracking changes to audio/MIDI devices,
243          MIDI instrument maps, MIDI instruments, FX sends, global volume.
244        - sampler was limited to load max. 200 instruments in the background
245          due to a constant size RingBuffer FIFO which is now replaced by a
246          dynamic (unlimited) size std::list FIFO
247        - added FX sends, these allow to route audio signals to arbitrary audio
248          output channels for being processed by external effect processors
249          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
250          controllers
251        - global (sampler wide) volume can now be controlled at runtime
252        - Implemented new, improved notification system
253        - fixed compilation errors regarding OSX
254          (patch by Toshi Nagata)
255        - implemented instruments database
256        - added support for escape sequences to the instruments database
257        - added highly experimental support for on-the-fly instrument editing
258          within the sampler's process (by using instrument editor plugins),
259          you'll notice the new "Registered instrument editors:" message on
260          startup, added a new LSCP command:
261          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
262          to spawn a matching instrument editor for the instrument on the
263          given sampler channel, the plugin path can be overridden at compile
264          time with ./configure --enable-plugin-dir=/some/dir
265        - added experimental code for synchronizing instrument editors hosted
266          in the sampler's process to safely edit instruments while playing
267          without a crash (hopefully) by either suspending single regions
268          wherever possible or if unavoidable whole engine(s)
269        - fixed several issues in fundamental "Thread" class: set scheduling
270          policy and priority on thread level, set a minimum stack size for
271          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
272          threads simply inherited properties of starting thread instead of
273          setting their own policy and priority
274        - minor fix in our automatic stack trace mechanism on crashes, the
275          main process did not wait for the stack trace process to finish
276          its output
277        - fixed some minor memory leaks
278        - reenabled assembly features support, at the moment only for
279          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
280        - minor assembly fix in x86 features detection (don't use the PIC
281          register, to avoid relocations in the text segment at runtime)
282        - POSIX callback functions of Thread.h are hidden
283    
284      * MIDI driver:
285        - dispatch bank select (MSB and LSB) messages
286    
287      * audio driver:
288        - the ALSA audio output driver parameters now reflect the correct
289          parameter value ranges for the respective selected sound card
290          (patch by Till Wimmer, a bit fixed and extended)
291    
292      * Gigasampler format engine:
293        - if a filter is used and EG2 finishes before EG1, let the voice
294          die when EG2 has finished (this fixes a problem with clicks and
295          voice starvation for some gigs)
296        - playback is no longer disabled during instrument loading
297        - all notes playing on a channel that changes its instrument keep
298          playing with the old instrument until they get a note off
299          command
300        - EG fix: a release value of zero could cause noises or crash
301        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
302        - EG fine tuning: when attack is zero the EG starts at a level
303          above max sustain level, which means that there is a decay phase
304          even if sustain is 100%
305        - more EG fixes: the level could sometimes go below zero and cause
306          noises or crashes
307        - minor fix of EGDecay (patch by Toshi Nagata)
308        - fixed compiler error when --enable-override-filter-type was
309          supplied to the configure script (fixes #46)
310        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
311          instead of a fix value
312        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
313          127 (solo mode) only kill voices if the respective mode really
314          changed
315    
316      * LSCP server:
317        - fixed compile time error for old Bison versions
318          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
319        - parser now supports extended ASCII character set
320          (up to ASCII code 255, i.e. includes now umlauts and accents)
321        - filename arguments in LSCP commands now allow to use escape
322          sequences, that is directly literal as one of: \', \", \\, \n, \r,
323          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
324          code value like \xf2) (fixes bug #24)
325        - the following LSCP commands now also support escape sequences for at
326          least one of their text-based parameters (i.e. name, description):
327          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
328          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
329          "SET DB_INSTRUMENT_DIRECTORY NAME",
330          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
331          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
332          "FIND DB_INSTRUMENT_DIRECTORIES"
333        - returns verbose syntax errors (line and column where syntax error
334          occured, the unexpected character and the actually expected, possible
335          character(s), the latter only if less than 5 possibilities)
336        - made sure that LSCP syntax is not affected by gigedit locale
337          settings
338        - bugfix regarding strings parameter lists: all comma separated lists
339          of strings were treated as being one string containing commas
340          (fixes #57)
341    
342      * Bug fixes:
343        - fixed crash occurring on certain LSCP scripts (Bug 39)
344        - another thread safety fix for lscp "load engine" and "set
345          channel audio output device"
346        - fixed a crash which occurs when reassigning the same engine
347          on a sampler channel with connected MIDI device
348        - fixed a crash which occurs when changing the number of ports of a MIDI
349          device connected to a sampler channel to number less then or equal
350          to the index of the port to which the sampler channel is connected.
351        - The previous bindings were not been disconnected when altering
352          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
353          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
354        - The active stream/voice count statistic was incorrect.
355        - notification events were not been sent for some sampler
356          channel changes
357        - added default min and max values to restrict the number of allowed
358          audio output channels and MIDI input ports
359        - the connection to the PCM interface is now closed when destroying
360          an audio output device
361        - files with slash in their path or filename could not be loaded
362    
363      * test cases:
364        - updated and fixed (haven't been touched in a while)
365    
366    Version 0.4.0 (24 November 2006)
367    
368      * packaging changes:
369        - changed deprecated copyright attribute to license; added ldconfig
370          to post-(un)install steps; added devel package for liblinuxsampler;
371          to linuxsampler.spec (RPM)
372        - install necessary development header files for allowing 3rd party
373          applications to link against liblinuxsampler
374        - liblinuxsampler's API documentation can be generated with 'make docs'
375          (Doxygen required)
376        - added benchmark to automatically detect the best triangle LFO
377          implementation (currently either an integer math solution or a
378          di-harmonic approximation), automatic detection can be overriden
379          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
380          configure script argument though (mandatory for cross-compilation)
381        - do not automatically pick optimized gcc flags if the user already
382          provided some on his own (as CXXFLAGS)
383        - added compile time option to disable processing of All-Notes-Off MIDI
384          messages
385        - added compile time options to allow disabling the various audio and
386          MIDI drivers
387        - fixed automatic GCC CPU switch detection on PPC
388          (patch by Ebrahim Mayat)
389    
390      * Gigasampler format engine:
391        - extensive synthesis optimization
392          (reimplementation of EGs and LFO(s), removed synthesis parameter
393          prerendering and the synthesis parameter matrix in general, splitting
394          each audio fragment into subfragments now where each subfragment uses
395          constant pitch and filter coefficients. The volume coefficient is
396          linearly interpolated inside a subfragment, unless
397          --disable-interpolate-volume is set.)
398        - fine tuning of the EG modulation parameters
399        - improved filter cutoff calculation by adding support for the
400          following gig parameters: Cutoff freq (used when no cutoff
401          controller is defined), Control invert, Minimum cutoff, Velocity
402          curve and Velocity range. The keyboard tracking now scales
403          cutoff frequency instead of resonance.
404        - added support for gig parameter Resonance.
405        - fixed bug in sysex handling (patch by Juan Linietsky)
406        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
407          which can be overridden with --enable-global-attenuation
408        - EG fixes: made the length of "attack hold" stage more
409          accurate. Release stage can now start before attack stage
410          ends. Cancel release didn't work when sustain was zero. Attack
411          time now has a minimal value to prevent clicks.
412        - fixed pitch changes larger than one octave
413        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
414        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
415          all modes can be altered via standard GM messages, that is CC5 for
416          altering portamento time, CC65 for enabling / disabling portamento
417          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
418        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
419          parameter) and crossfade
420        - added support for the "attenuation controller threshold" gig
421          parameter
422        - added smoothing of volume changes caused by control change
423          messages
424        - sample loop parameters are now taken from the DimensionRegion
425          instead of the wave chunk
426        - fixed keyswitching for v3 gigs with a number of keyswitch splits
427          not equal to a power of two
428        - reimplementation of the filter algorithm. The new filter is more
429          accurate and supports all gig filter types, including bandreject
430          and lowpass turbo.
431        - real support for 24 bit samples - samples are not truncated to
432          16 bits anymore
433        - support for aftertouch (channel pressure, not polyphonic
434          aftertouch)
435        - LFO1 behaviour fixed (dampening from max volume instead of
436          amplifying from 0)
437    
438      * LSCP server:
439        - fixed application exit on broken pipe error (fixes bug #20)
440        - fixed the notification messages delay due to lack of
441          network activity (fixes bug #26)
442        - fixed parser bug which occured on space(s) within device parameters
443          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
444    
445      * audio driver:
446        - added aRts audio output driver (by no means RT safe)
447    
448      * MIDI driver:
449        - fixed legacy sysex code which caused dispatching of MIDI SysEx
450          messages several times instead of once
451        - API extension for MIDI drivers which already supply exact time stamps
452          for events (i.e. for offline rendering based MIDI drivers)
453        - added checks for bad MIDI data
454    
455      * linuxsampler application:
456        - show available sampler engine types on startup
457    
458      * general changes:
459        - support for muting sampler channels and solo mode of the same, two new
460          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
461          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
462          introduced for this, the behavior is the same like on a mixer console
463          (patch by Grigor Iliev, a bit adjusted). Also added configure option
464          --enable-process-muted-channels which can be used to enable the
465          processing of muted channels.
466        - support for sostenuto pedal
467        - support for monitoring the total number of active voices
468          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
469          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
470        - fixed some memory management errors
471        - fixed some concurrency problems that could lead to crashes when
472          LSCP commands were executed
473        - fixed crash when instrument loading failed previously on the same
474          sampler channel (fixes bug #36)
475    
476    Version 0.3.3 (15 July 2005)
477    
478      * packaging changes:
479        - fixed compilation with gcc 4.0
480    
481      * Gigasampler format engine:
482        - LFO preprocessing was performed even though the respective LFO was
483          disabled by the instrument patch (minor efficiency fix)
484        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
485          for volume ramp downs in the same fragment (needed for current voice
486          stealing implementation) then simply inform the user with a warning
487          about possible click sounds and reduce the volume ramp down
488          appropriately instead of cancelling the audio device connection
489    
490    Version 0.3.2 (24 June 2005)
491    
492      * packaging changes:
493      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
494        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
495    * support for the gig parameters for "release velocity response"      - hand-crafted assembly optimization code can be disabled with
496      curves        './configure --disable-asm' (definitely not recommended)
497    * fine tuning of the EGADSR envelope      - fixed 'make dist' rule to include all necessary files
498        - require automake (>= 1.5) for 'make -f Makefile.cvs'
499          (due to 'dist-bzip2' automake option)
500    
501      * Gigasampler format engine:
502        - support for the gig parameters for "release velocity response" curves
503        - fine tuning of the EGADSR envelope
504        - volume of release triggered samples now depends on note-on velocity,
505          note length and gig parameter "release trigger decay" instead of
506          note-off velocity.
507        - revised voice stealing
508          (fixes crash and endless loop caused by voice stealing)
509        - don't reset scale tuning on instrument or audio output device change
510        - handle key group conflicts right at the beginning of each fragment
511          instead of when the respective voice is actually launched
512          (fixes undefined behavior if stolen voices belonged to a key group -
513          this case was followed by a "killed voice survived" error message)
514        - fixed minor issue with null/silence samples
515          (those stole voices even though they don't need a voice at all which
516          resulted in "voice stealing didn't work out" messages)
517        - don't reset volume, pan, pitch and MIDI controller values on
518          instrument or audio output device change
519    
520      * LSCP server:
521        - fixed some crashes (patch by Grigor Iliev, fixes #19)
522        - fixed LSCP event "CHANNEL_INFO" notification
523          (e.g. did not notify on volume changes or MIDI program change events)
524    
525      * linuxsampler application:
526        - added command line parameters --lscp-addr and --lscp-port to override
527          default IP address and port of LSCP server
528    
529  Version 0.3.1 (24 May 2005)  Version 0.3.1 (24 May 2005)
