# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9        - Fixed unintended volume fade-in of voices under certain conditions.
10    
11      * Gigasampler/GigaStudio format engine:
12        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13          cutoff settings.
14    
15      * general changes:
16        - fixed printf type errors (mostly in debug messages)
17        - use unique_ptr instead of auto_ptr when building with C++11
18        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19          allowing to sort data efficiently in real-time safe manner.
20        - RTList class: added methods for moving/inserting elements to arbitrary
21          position within a list.
22        - RTList class: added method fromPtr() for creating an Iterator object from
23          a raw element pointer.
24        - Attempt to partly fix resetting engine channels vs. resetting engine, an
25          overall cleanup of the Reset*(), ConnectAudioDevice(),
26          DisconnectAudioDevice() API methods would still be desirable though,
27          because the current situation is still inconsistent and error prone.
28        - Active voices are now internally grouped to "Note" objects, instead of
29          being directly assigned to a keyboard key. This allows more fine graded
30          processing of voices, which is i.e. required for certain instrument
31          script features.
32        - Fix: Release trigger voices were not spawned on sustain pedal up
33          (CC #64) events.
34        - Fix: Release trigger voices can now also distinguish correctly between
35          note-off and sustain pedal up events.
36        - All engines: Increased ramp speed of volume smoother and pan smoother
37          (while slow rate of crossfade smoother is preserved) to allow quick
38          volume and pan changes by instrument scripts for instance.
39        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40          properly and thus were ignored for certain uses.
41        - Added new C++ API method
42          VirtualMidiDevice::SendChannelPressureToSampler().
43        - windows, 32-bit: fixed potential crashes by making sure the stack in
44          sub threads is 16-byte aligned
45        - fixed numerous compiler warnings
46        - Fixed invalid (note-on) event ID being assigned to new Note objects.
47    
48      * packaging changes:
49        - removed unnecessary dependency to libuuid
50          (originated by libgig's usage of it)
51        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52          auto detect whether it (sh/c)ould output its messages in color.
53    
54      * Real-time instrument scripts:
55        - Implemented scheduler for delayed MIDI events and for suspended scripts.
56        - Built-in script function "wait()": implemented support for function's
57          "duration-us" argument, thus scripts using this function are now
58          correctly resumed after the requested amount of microseconds.
59        - Built-in script function "play_note()": implemented support for
60          function's "duration-us" argument, thus notes triggered with this
61          argument are now correctly released after the requested amount of
62          microseconds.
63        - Fix: script events were not cleared when engine channel was reset,
64          potentially causing undefined behavior.
65        - Fixed crash which happened when trying to reference an undeclared
66          variable.
67        - Built-in script function "play_note()": Added support for passing
68          special value -1 for "duration-us" argument, which will cause the
69          triggered note to be released once the original note was released.
70        - Instrument script classes now exported with the liblinuxsampler C++ API.
71        - Added new API method ScriptVM::syntaxHighlighting() which provides
72          a convenient syntax highlighting backend for external instrument
73          script editor applications.
74        - Added new C++ API class "ScriptVMFactory".
75        - Extended parser issues to provide not only first line and first
76          column, but also last line and last column of issue (thus marking
77          the precise span of the issue within the source code).
78        - Reload script automatically after being modified by an instrument
79          editor.
80        - NKSP language grammar correction: allow empty event handler bodies
81          like "on note end on".
82        - Implemented built-in script function "change_vol()".
83        - Implemented built-in script function "change_tune()".
84        - Implemented built-in script function "change_pan()".
85        - Implemented built-in script function "change_cutoff()".
86        - Implemented built-in script function "change_reso()".
87        - Implemented built-in script function "event_status()".
88        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90          "event_status()" function.
91        - NKSP language: Added support for bitwise operators ".or.", ".and."
92          and ".not.".
93        - NKSP language scanner: Fixed IDs matching to require at least one
94          character (i.e. when matching function names or variable names).
95        - NKSP language scanner: disabled unusued rules.
96        - Fixed behavior of play_note() and note_off() functions which must
97          be distinguished engine internally from "real" MIDI note on/off
98          events in order to avoid misbehaviors like hanging notes.
99        - Implemented built-in script variable "$KSP_TIMER".
100        - Implemented built-in script variable "$NKSP_REAL_TIMER".
101        - Implemented built-in script variable "$NKSP_PERF_TIMER".
102        - Implemented built-in script variable "$ENGINE_UPTIME".
103        - Implemented built-in script function "inc()".
104        - Implemented built-in script function "dec()".
105        - NKSP language fix: division expressions were evaluated too often.
106        - NKSP language fix: string concatenation operator was right
107          associative instead of left (to right).
108        - NKSP language correction: allow empty statements in entire language
109          (i.e. "if end if").
110        - Implemented built-in script function "stop_wait()".
111        - Implemented built-in script variable "$NI_CALLBACK_ID".
112        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114        - Added support for read-only built-in variables (respectively
115          handled by the script parser).
116        - Added built-in script constant "$NI_CB_TYPE_INIT".
117        - Added built-in script constant "$NI_CB_TYPE_NOTE".
118        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120        - NKSP Language: Added support for user defined script functions.
121        - Implemented built-in script function "change_attack()".
122        - Implemented built-in script function "change_decay()".
123        - Implemented built-in script function "change_release()".
124        - Fixed all change_*() built-in script functions to apply their
125          synthesis parameter changes immediately in case the respective note
126          was triggered at the same time, instead of scheduling the parameter
127          change, especially because it would cause some parameter types's
128          changes either to be ramped (i.e. change_vol()) or other types even
129          to have not effect at all (i.e. change_attack()).
130        - Implemented built-in script function "sh_left()".
131        - Implemented built-in script function "sh_right()".
132        - Implemented built-in script function "min()".
133        - Implemented built-in script function "max()".
134        - NKSP Fix: "init" event handler was not always executed when a script
135          was loaded.
136        - NKSP built-in wait() script function: abort script execution if
137          a negative or zero wait time was passed as argument (since this is
138          a common indication of a bug either of the script or even of the
139          engine, which could lead to RT instability or even worse).
140        - ScriptVM: Implemented automatic suspension of RT safety
141          threatening scripts.
142        - Provide more user friendly error messages on syntax errors.
143        - Fixed NKSP parser warning "Not a statement" when assigning an
144          initializer list to an array variable.
145        - Implemented built-in script array variable "%ALL_EVENTS".
146        - Implemented built-in script function "in_range()".
147        - Implemented built-in script function "change_amp_lfo_depth()".
148        - Implemented built-in script function "change_amp_lfo_freq()".
149        - Implemented built-in script function "change_pitch_lfo_depth()".
150        - Implemented built-in script function "change_pitch_lfo_freq()".
151        - Implemented built-in script function "change_vol_time()".
152        - Implemented built-in script function "change_tune_time()".
153        - Implemented built-in script function "fade_in()".
154        - Implemented built-in script function "fade_out()".
155        - Fixed acceptance of wrong data type of parameters passed to built-in
156          script functions "change_vol()", "change_tune()", "change_pan()",
157          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160        - Added built-in script function "get_event_par()" and implemented some
161          of its possible parameter selections.
162        - Added built-in script function "set_event_par()" and implemented some
163          of its possible parameter selections.
164        - Fixed a bunch of scheduler time related bugs.
165        - Fixed polyphonic variables not being reset to zero after usage.
166        - Built-in "ignore_event()" function: argument is now optional, like with
167          built-in function "ignore_controller()".
168        - Implemented built-in script function "change_velo()".
169        - Implemented built-in script function "change_note()".
170        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171          intuitive behavior if used in combination with "change_vol_time()" or
172          "change_tune_time()" respectively: now tuning/volume changes are only
173          assigned (without delay) immediately to a new note if the respective
174          timing function has not been called before, otherwise the volume/tuning
175          changes are automatically faded (before, only the event's time stamp was
176          relevant).
177         - Implemented built-in script function "array_equal()".
178         - Implemented built-in script function "search()".
179         - Implemented built-in script function "sort()".
180         - NKSP Fix: Never suspend "init" event handlers.
181         - Implemented built-in script function "same_region()" (currently only
182           available for gig format engine).
183    
184      * Instruments DB:
185        - Fixed memory access bug of general DB access code which lead to
186          undefined behavior.
187        - Cleanup of instruments DB file creation and opening code.
188        - The instrument DB path of linuxsampler's --create-instruments-db argument
189          is now optional, if it is missing, then a default location is used.
190        - Added support for scanning SFZ (.sfz) files.
191        - Added support for scanning Sound Font (.sf2) files.
192        - Fixed undefined DB transaction behavior.
193

198        - Mac OS X: support the new dir for Core Audio SDK
199        - Mac OS X: fixed building outside source directory
200        - made sure all source files for hostplugins are included when
201          doing "make dist"
202        - removed empty directories left from the cvs to svn migration
203        - fixed compilation with gcc 4.6.1
204        - another "make dist" fix, for the LV2 plugin
205        - made --enable-pthread-testcancel default on Mac OS X
206        - minor Makefile fix for building lscpparser when build and source
207          directories are separate
208        - Mac OS X: made it possible to specify plugin installation dir to
209          configure
210        - Mac OS X: Makefile fix for the install-strip target
211        - fixed compilation with gcc 4.7
212        - fixed configure script error with old autoconf versions

215        - modernized configure script
216        - fixed linkage error when building with
217          LDFLAGS="-Wl,--no-undefined" (#190)
218        - fixed compilation with Clang 3.2
219        - removed usage of deprecated Automake variable INCLUDES

226          on the process's main thread
227        - fixed build error on newer MinGW
228        - support building with older jack versions
229        - support building with spaces in vst sdk path
230        - enabled automake 'subdir-objects' option and moved external
231          source references (vst, au, asio) from makefiles to cpp files,
232          in order to get rid of warnings from automake 1.14
233    
234      * general changes:
235        - Refactoring: moved the independent code from
236          the Gigasampler format engine to base classes
237        - command line option '--profile' is currently disabled, since the
238          respective profiling code is currently broken
239        - Introduced support for optional environment variable
240          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
241          where the sampler shall look for instrument editor plugins
242          (patch by Luis Garrido, slightly modified).
243        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
244        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
245        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
246          note (in this implementation of the sampler its simply hard routed to
247          the 1st effect send of the sampler channel, no matter what the actual
248          effect type is)
249        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
250          note (in this implementation of the sampler its simply hard routed to
251          the 2nd effect send of the sampler channel, no matter what the actual
252          effect type is)
253        - implemented support for internal LADSPA effects
254        - raised limit of program change queue from 100 to 512
255          (as suggested by Alex Stone)
256        - implemented sine LFO, pulse LFO and saw LFO
257        - experimental support for per voice equalization
258        - added command line option --exec-after-init
259        - Introduced new C++ API method:
260          EngineChannel::InstrumentFileName(int index)
261          allowing to retrieve the whole list of files used for the loaded
262          instrument on an engine channel (a.k.a. part). Some GigaStudio
263          instruments for example are splitted over several files like
264          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
265        - Added new C++ API method Sampler::GetGlobalMaxVoices().
266        - Added new C++ API method Sampler::GetGlobalMaxStreams().
267        - Added new C++ API method Sampler::SetGlobalMaxVoices().
268        - Added new C++ API method Sampler::SetGlobalMaxStreams().
269        - Various "const" and "restrict" optimizations.
270        - all engines: add pan CC value to instrument pan parameter before
271          applying panning, instead of using two separate pan functions in
272          series (#182)
273        - added a lock guard class for exception safe mutex handling and
274          used it everywhere appropriate
275        - Immediately apply scale tuning changes to active voices.
276        - Exposed scale tuning to C++ API (along to the already existing standard
277          SysEx way).
278        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
279          and broken for ppc64. (Seq_cst loads and stores are actually not
280          used in LS, so the bug wasn't noticable.)
281        - lsatomic.h: added ARMv7 support
282        - Added support for multiple MIDI input ports per sampler channel (and
283          added various new C++ methods for this new feature / design change, old
284          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
285          as deprecated but are still there and should provide full behavior
286          backward compatibility).
287        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
288          unsafe and caused compilation error with clang 2.x).
289        - Bugfix: only process the latest MIDI program change event.
290        - Introducing the LSCP shell, which provides convenient control of the
291          sampler from the command line by providing LSCP aware features.
292        - VirtualMidiDevice: Added support for program change.
293        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
294        - VirtualMidiDevice: Added support for pitch bend.
295        - Aftertouch: extended API to explicitly handle channel pressure and
296          polyphonic key pressure events (so far polyphonic pressure was not
297          supported at all, and channel pressure was rerouted as CC128 but not
298          used so far).
299        - Added initial support for real-time instrument scripts. The script VM
300          code is shared by all sampler engine implemementations, however only the
301          gig file format currently provides support for storing instrument scripts
302          (as LinuxSampler extension to the original GigaStudio 4 format).
303    
304      * Gigasampler format engine:
305        - implemented the "round robin keyboard" dimension
306        - fixed round robin and random dimensions for cases when number of
307          dimension zones is not a power of two
308        - made round robin use a counter for each region instead of each
309          key
310        - bugfix: pitch LFO controller "internal+aftertouch" was broken
311        - bugfix: filter keyboard tracking was broken
312        - filter performance fix (an unnecessary copy was made of the
313          filter parameters in each sub fragment)
314        - handle special case when pan parameter in gig file has max or
315          min value
316        - Exclusive Groups: don't ever stop voices of the same note,
317          doesn't sound naturally with a drumkit
318        - fixed EG1 modulation when attack or release is zero
319        - Fixed support for 'aftertouch' attenuation controller.
320        - Fixed crash that happened with velocity split sounds under certain
321          conditions (see also previous commit on libgig).
322        - fixed behaviour of filter LFO
323    
324      * SFZ format engine:
325        - Initial implementation (not usable yet)
326        - added support for v2 multiple stage envelope generators
327        - added a fine-tuned v1 envelope generator instead of using the
328          one from the gig engine
329        - fixed memory leak and memory handling errors
330        - added support for trigger=first, trigger=legato and sw_previous
331        - allow non-numerical key values ("C#4" for example)
332        - "key" opcode now sets pitch_keycenter too
333        - fixed error when unloading instrument with same sample used by
334          multiple regions
335        - added some opcode aliases, like loopmode for loop_mode, to be
336          more compatible
337        - added support for trigger=release and rt_decay
338        - added support for off_mode=normal
339        - added support for random, seq_position, seq_length and volume
340        - added v1 LFO opcodes to parser (no support in engine yet)
341        - added support for amp_veltrack and amp_velcurve_N
342        - fine-tuned the default velocity curve
343        - added support for transpose
344        - fixed crash when using sw_down/up
345        - improved logic for sw_lokey/hikey/up/down/last
346        - added more v1 aliases to parser
347        - reduced memory usage for sfz data
348        - RT-safeness: avoid malloc in audio thread
349        - fixed a bug that could cause voice stealing to fail
350        - optimized sample lookup
351        - improved support for exclusive groups (group, off_by and
352          off_mode)
353        - added support for controller triggered regions (on_locc/on_hicc)
354        - added support for loop_mode=one_shot
355        - fixed playback of 16 bit wav files on big endian CPUs
356        - added support for Ogg Vorbis sample files
357        - use loop markers from sample file if loop_start and loop_end are
358          not set in sfz file
359        - implemeted filters. Filter types: lowpass, bandpass, bandreject
360          and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
361          cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
362          cutoff_cc, cutoff_chanaft.
363        - bugfix: zero ampeg_sustain didn't work
364        - added support for velocity effect on amplifier envelope time
365          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
366          ampeg_vel2release)
367        - added support for EG hold (ampeg_hold)
368        - added support for sample offset (offset)
369        - use the newly introduced signal units model
370        - implemented opcodes lfoN_delay,
371          lfoN_freq, lfoN_pan, lfoN_cutoff, lfoN_resonance
372        - implemented opcodes ampeg_delay, ampeg_vel2delay

503          incorrectly set to two. This caused silence in Cubase 5.
504        - save engine type (gig, sfz or sf2) in plugin state
505        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
506          64 bit Windows

561        - MME bugfix: driver wasn't closed properly
562        - CoreMIDI: automatically connect to all input sources by default (driver
563          parameter "AUTO_BIND").

692        - bugfix: calling SET VOICES (which Fantasia does on start and
693          refresh) could cause instruments to be unloaded
694        - Mac OS X: fixed name collision of enum in EffectControl and
695          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
696        - Mac OS X: fixed hanging threads
697        - Windows: disabled the previous thread fix on non-Mac systems, as
698          it caused hanging threads on Windows
699        - Fixed possible crashes due to corrupted MIDI/audio device list
700          after MIDI/audio device creation failure
701        - When creating MIDI instrument map entries with "PERSISTENT" type, the
702          instruments were uselessly precached with zero samples, however it still
703          took the full preloading time and on 1st program change the respective
704          instrument was completely reloaded again.
705        - fixed handling of rapid bank select and program change messages
706          sent to the same sampler channel (patch from the Open Octave
707          project, slightly adjusted)
708        - fixed crash when trying to create an effect instance with controls
709          which min and/or max values depend on the sample rate
710        - fixed bug #162
711        - bugfix: LADSPA_PATH was not evaluated correctly when containing
712          multiple paths (#165)
713        - thread safety fixes for the instrument loading thread
714        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
715          (#176)
716        - more thread safety fixes for the instrument loading thread
717        - sfz/sf2 engine: fixed crash when using small audio fragment size
718        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
719        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
720          introduced in previous fix)
721        - fixed crash when a channel received a program change while
722          playing a note in a key group
723        - fixed erroneous error message piping in VoiceBase.h
724          (labelled "Disk stream not available in time")
725        - Update effects on sample rate & period size changes (to avoid
726          crashes and noise on such transitions).
727        - ignore missing LADSPA paths without ignoring valid LADSPA paths
728          (fixes #208)
729        - Fixed bug in LSCP grammar definition which caused a statement like
730          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
731          practically irrelevant, however it caused problems with the new LSCP
732          shell's auto completion feature).
733        - Fixed MIDI program change messages being ignored if quickly executed
734          after each other (fixes #231).
735    
736    Version 1.0.0 (31 July 2009)
737    
738      * packaging changes:
739        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
740          causing e.g. the libgig test to fail when
741          "./configure --disable-jack-driver" was used
742          (patch by Alexis Ballier)
743        - fixed compilation with gcc 4.3
744        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
745        - fixed configure so it detects x86_64 (#107)
746        - fixes for building with newer MinGW versions
747        - fix for building with bison 2.4 (#111)
748        - fixed building with libgig installed in a non-standard directory
749        - minor fix in configure for mmsystem.h detection on MinGW
750        - Windows: look for editor plugins and Fantasia using base
751          directory of liblinuxsampler dll (look in the same directory and one
752          directory above)
753        - configure script fix: removed unconditional use of SSE
754        - fixed building with sqlite installed in a non-standard directory
755        - when cross-compiling, don't try to create instruments.db
756        - fix for new mingw-w64 version, which has usleep
757    
758      * general changes:
759        - bugfix: on some POSIX systems instrument editor plugins refused to
760          load as we used a non-portable Linux specific struct field
761          (fixes bug #70, patch by Ronald Baljeu)
762        - fixed endless loop which occured when loading an instrument editor
763          plugin DLL on Windows systems failed
764        - fixed memory leaks that occurred when liblinuxsampler was unloaded
765        - optimized the SynchronizedConfig class so it doesn't wait
766          unnecessarily long after an update
767        - added support for notifying instrument editors on note-on / note-off
768          events (e.g. to highlight the pressed keys on the virtual keyboard
769          of gigedit)
770        - added support for triggering notes by instrument editors (see above)
771        - be verbose on DLL load errors (on Linux)
772        - fixed di-harmonic triangle LFO implementation (this LFO implementation
773          is only used by very few systems, most pick the int math
774          implementation, which is usually faster)
775        - fixes for audio drivers with varying buffer sizes
776        - experimental support for running LinuxSampler as a DSSI, LV2 and
777          VST plugin
778        - notification events for stream/voice count statistics are now sent
779          only when there are actual changes
780        - added memory ordering constraints to improve stability on
781          multi-core and multi-cpu systems
782        - maximum voices and disk streams can now be altered at runtime
783        - fixed CPU feature detection on x86_64 (maybe fixes #108)
784        - automatic stacktrace mechanism is now turned off by default and can
785          be switched on by command line option "--stacktrace" (the automatic
786          stacktrace mechanism seems to be broken on most systems at the moment)
787        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
788          a pointer to the launched InstrumentEditor object
789        - added optional 3rd party user data parameter for following
790          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
791          InstrumentEditor::Launch(),
792          InstrumentManager::LaunchInstrumentEditor()
793        - theoretical fix: made SynchronizedConfig follow C++0x memory
794          model more strictly
795        - fixes for using large audio device buffers
796        - Windows: add the installation directory to the DLL search path
797          when loading an editor plugin (solves problems with VST and
798          gigedit on systems with other GTK versions installed)
799        - updated linuxsampler man page
800    
801      * audio driver:
802        - removed the nonsense audio channel constraint (which was hard coded to
803          max. 100 audio channels) for most audio drivers
804        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
805          opposed to the LSCP specs
806        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
807          reflected the wrong value
808        - fixed a memory management bug in ASIO driver
809        - Makefile fix: JACK_CFLAGS wasn't used
810        - JACK: use jack_client_open instead of the deprecated
811          jack_client_new
812        - added (experimental) CoreAudio driver
813        - applied old fixes to the ASIO driver that were included in the
814          previous binary release but accidentally never committed to CVS
815          (fixes #117)
816        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
817          win64)
818        - VST: added support for sample rate and buffer size changes
819        - VST: close editor (Fantasia) when the VST is removed
820        - VST: avoid opening Fantasia more than once for each VST instance
821        - VST: export main function as "main" on Linux too (fix for
822          energyXT)
823        - VST: changed number of output channels from one stereo to 16
824          stereo
825        - added channel routing, fxsends and midi maps to the settings
826          stored in the plugin state
827        - performance optimization of AudioChannel::MixTo() and
828          AudioChannel::CopyTo() methods using GCC vector exensions
829          (if available)
830        - ASIO fixes: avoid initializing the device twice, avoid throwing
831          exception when getting parameters from a disconnected device
832    
833      * MIDI driver:
834        - added JACK MIDI driver
835        - dispatch bank select as ordinary CC as well, the user might seriously
836          want to (mis)use it for some purpose ("fixed" in all current MIDI
837          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
838        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
839          CoreMidi or AU
840        - fixed mingw-w64 compilation error in MME driver
841        - made program change handling in MIDI thread real-time safe by
842          moving the logic to a non-RT thread
843        - fixed minor memory leak in ALSA driver
844    
845      * instruments database:
846        - avoid time consuming samples scanning when adding instruments
847          to the instruments database
848        - added support for handling lost files in the instruments database
849        - Implemented option for adding instruments in separate directories
850          in the instruments database
851          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
852        - work-around for missing fnmatch function on Windows to make
853          instrument database compilable
854        - added instrument database support on Windows
855          works with both standalone mode and VST plugin.
856          the instruments DB file is located in
857          %USERPROFILE%\.linuxsampler\instruments.db which allows different
858          databases for each windows user
859          if no DB is present it automatically creates the .linuxsampler subdir
860          and then creates an empty DB
861        - fixed recursive import, which was broken on Windows
862    
863      * Gigasampler format engine:
864        - fixed a memory leak that could happen when a channel was deleted
865          while notes were playing
866        - made it possible to load an instrument even if the audio thread
867          isn't running
868        - added partial support for the "Controller Triggered" MIDI rule,
869          enough for piano gigs with pedal noise samples
870        - minor fix: only mark FX sends as being modified if really the
871          respective FX send MIDI controller was used
872        - added support for GM global device volume SysEx message
873          (can be selected at compile time to either apply globally to the
874          whole sampler [default] or only to the sampler channels that are
875          connected to the respective MIDI input port the SysEx message arrived
876          on)
877        - bugfix: notes triggered at position 0 in the audio buffer were
878          sometimes wrongly killed in the same buffer, causing no sound to
879          be played
880        - added support for chromatic / drumkit mode Roland GS Sysex message
881          which is usally used to switch a part between chromatic sounds and
882          drumkit sounds (as opposed to their common default setting of MIDI
883          part 10 being a drumkit part and all other ones chromatic parts), in
884          LS however one can switch between the first 16 MIDI instrument maps
885          defined for the sampler
886        - made it possible to create multiple sample channels even if the
887          audio thread isn't running
888        - fixed crash when removing channel with active voices (#116)
889        - bugfix: on sample reference changes (instrument editor), only
890          un-cache the respective sample if it's really not used by any
891          sampler engine anymore
892        - re-cache samples in case they were changed by an instrument editor,
893          e.g. when a sample was added while playing (#82)
894        - fixed hanging notes which occured when note-off event had the exact
895          same time stamp as the voice's note-on event and occured both in the
896          same audio fragment cycle (fixes bug #112)
897        - added support for the "fine tune" and "pitch bend range"
898          instrument-level gig parameters
899        - fixed minor artifacts in pitch bend handling
900        - added support for GS Reset SysEx message
901        - allow gig files to use unlimited downward pitch shifting
902        - added a limit check for upward pitch shifting
903        - bugfix: sometimes, when playing a note twice fast, the second
904          note was silent
905        - fixed crash happening when a pitch bend event arrived at the
906          same time a new instrument was loading
907    
908      * LSCP server:
909        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
910          react on MIDI data arriving on certain sampler channels (so far only
911          Note-On and Note-Off events are sent via this LSCP event)
912        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
913          react on MIDI data arriving on certain MIDI input devices (so far only
914          Note-On and Note-Off events are sent via this LSCP event)
915        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
916          SET DB_INSTRUMENT FILE_PATH
917        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
918          frontends to send MIDI messages to specific sampler channel
919        - added two additional fields to GET FILE INSTRUMENT INFO command -
920          KEY_BINDINGS and KEYSWITCH_BINDINGS
921        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
922          was incorrect
923        - Optimized the retrieval of the MIDI instrument mappings
924        - added new LSCP command "SET VOICES" to globally alter the maximum
925          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
926          be triggered respectively
927        - added new LSCP command "SET STREAMS" to globally alter the maximum
928          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
929          which will be triggered respectively
930        - bugfix: retry if "select" returns EINTR (this fixes a crash when
931          a gigedit file dialog is opened)
932        - close all connections when LSCPServer is deleted
933        - hard close of all sockets on exit
934        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
935          driver
936    
937      * Bug fixes:
938        - fixed a crash which occurs when removing a sampler channel waiting
939          to start instrument loading after another channel
940        - fixed a crash which occurs when removing a sampler channel with
941          instrument loading in progress (bug #113)
942        - fixed termination caused by uncaught exception when adding MIDI
943          instrument with PERSISTENT load mode
944        - fixed possible iterator invalidations when resetting the sampler
945        - fixed memory leaks when issuing the following LSCP commands:
946          GET AUDIO_OUTPUT_DRIVER INFO
947          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
948          GET MIDI_INPUT_DRIVER INFO
949          GET MIDI_INPUT_DRIVER_PARAMETER INFO
950        - fixed possible compilation error when sqlite is not present
951        - fixed orphaned pointers when setting maximum voices limit (bug #118)
952        - fixed crash when changing the audio output device of a sampler
953          channel with loaded instrument and start playing notes
954        - fixed endless loop in Engine::SuspendAll() (bug #120)
955        - fixed a low-level atomic load function that was broken on 64-bit
956          PowerPC, which probably could cause crashes on that platform
957        - fixed a memory management error which could cause a crash when a
958          plugin was unloaded
959        - bugfix: two private structs had the same name, which could cause
960          problems if the linker chose the wrong constructor
961        - fixed low-level ConditionServer usage bug that caused lockups on
962          Windows
963    
964    
965    Version 0.5.1 (6 December 2007)
966    
967      * packaging changes:
968        - added autoconf checks for pthread library
969        - added autoconf check for pthread bug found on certain NPTL-enabled
970          glibc versions (see Gentoo bug report #194076)
971        - added autoconf checks for MS Windows
972    
973      * general changes:
974        - bugfix: the thread used by an editor plugin didn't die when the
975          editor closed
976        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
977          out all the space. operator--() did not apply size_mask after
978          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
979          order to avoid problems with the _NonVolatileReader functions.
980        - bugfix: Stream.h: added a missing divide by BytesPerSample in
981          GetWriteSpace(). Since this function is currently only used in
982          the stream's qsort() compare function, it didn't trigger any
983          bugs.
984        - Resampler.h, Synthesizer.h: cubic interpolation now works in
985          24bit mode too. Faster method to read 24bit words on little
986          endian machines (x86): replaced 3 byte reads + shifts with a 1
987          unaligned 32bit read and shift
988        - experimental support for MS Windows (MIDI input via MME, AUDIO
989          output via ASIO)
990        - made handling of SIGINT signal (Ctrl-C) a bit more robust
991        - support for monitoring the total number of active disk streams
992          (new LSCP commands: GET TOTAL_STREAM_COUNT,
993          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
994    
995      * AUDIO driver:
996        - added Windows ASIO low latency audio driver
997    
998      * MIDI driver:
999        - added MME Windows MIDI driver
1000    
1001      * LSCP server:
1002        - added support for Windows style path / filenames, however with
1003          forward slash path separators instead of backslash
1004          (i.e. "C:/foo/bar.gig")
1005        - allow naughty liblscp to send non-string device parameters within
1006          apostrophes as well
1007        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1008          "LIST FILE INSTRUMENTS <file>" and
1009          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1010          about an arbitrary instrument file on the system where the sampler is
1011          running on
1012    
1013    Version 0.5.0 (15 October 2007)
1014    
1015      * packaging changes:
1016        - config.h is not going to be installed along with liblinuxsampler's
1017          API header files anymore
1018        - only the API relevant header (and source) files will be exported to
1019          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1020        - added completely new XCode project files for Mac OSX which is now
1021          capable to execute our autoconf environment, thus no need anymore
1022          to maintain the compile time configuration file (osx/version.h) for
1023          OSX manually (patch by Toshi Nagata)
1024        - fixed buggy boolean --enable-foo / --disable-foo configure script
1025          parameters
1026        - global.h now only covers global definitions that are needed for the
1027          C++ API header files, all implementation internal global definitions
1028          are now in global_private.h
1029        - atomic.h is not exposed to the C++ API anymore
1030        - no need to include config.h anymore for using LS's API header files
1031        - fixed warnings in API doc generation
1032    
1033      * general changes:
1034        - replaced the old, confusing MIDI program change mechanism by a
1035          flexible MIDI instrument mapper which allows to map arbitrary
1036          (MIDI bank, MIDI program) pairs with arbitrary
1037          (engine type, instrument file, file index) triplets which will be
1038          loaded on the respective channel when such MIDI program change
1039          messages arrive, beside that, each entry allows to define a life-time
1040          strategy for the instrument, so the user can define whether the
1041          instrument should i.e. be permanently loaded (to be able to switch
1042          quickly among sounds) or i.e. loaded just on demand when the
1043          respective program change arrives (to safe RAM space), as well as a
1044          global volume factor for each entry, so the user can adjust the volume
1045          dynamic of his mapped instrument collection without having to modify
1046          the instrument files, also one can manage arbitrary amount of such
1047          MIDI instrument maps and assign each sampler channel individually
1048          a certain map, so that i.e. separation of normal instruments and
1049          drumkits is possible
1050        - new notification events for tracking changes to audio/MIDI devices,
1051          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1052        - sampler was limited to load max. 200 instruments in the background
1053          due to a constant size RingBuffer FIFO which is now replaced by a
1054          dynamic (unlimited) size std::list FIFO
1055        - added FX sends, these allow to route audio signals to arbitrary audio
1056          output channels for being processed by external effect processors
1057          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1058          controllers
1059        - global (sampler wide) volume can now be controlled at runtime
1060        - Implemented new, improved notification system
1061        - fixed compilation errors regarding OSX
1062          (patch by Toshi Nagata)
1063        - implemented instruments database
1064        - added support for escape sequences to the instruments database
1065        - added highly experimental support for on-the-fly instrument editing
1066          within the sampler's process (by using instrument editor plugins),
1067          you'll notice the new "Registered instrument editors:" message on
1068          startup, added a new LSCP command:
1069          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1070          to spawn a matching instrument editor for the instrument on the
1071          given sampler channel, the plugin path can be overridden at compile
1072          time with ./configure --enable-plugin-dir=/some/dir
1073        - added experimental code for synchronizing instrument editors hosted
1074          in the sampler's process to safely edit instruments while playing
1075          without a crash (hopefully) by either suspending single regions
1076          wherever possible or if unavoidable whole engine(s)
1077        - fixed several issues in fundamental "Thread" class: set scheduling
1078          policy and priority on thread level, set a minimum stack size for
1079          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1080          threads simply inherited properties of starting thread instead of
1081          setting their own policy and priority
1082        - minor fix in our automatic stack trace mechanism on crashes, the
1083          main process did not wait for the stack trace process to finish
1084          its output
1085        - fixed some minor memory leaks
1086        - reenabled assembly features support, at the moment only for
1087          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1088        - minor assembly fix in x86 features detection (don't use the PIC
1089          register, to avoid relocations in the text segment at runtime)
1090        - POSIX callback functions of Thread.h are hidden
1091    
1092      * MIDI driver:
1093        - dispatch bank select (MSB and LSB) messages
1094    
1095      * audio driver:
1096        - the ALSA audio output driver parameters now reflect the correct
1097          parameter value ranges for the respective selected sound card
1098          (patch by Till Wimmer, a bit fixed and extended)
1099    
1100      * Gigasampler format engine:
1101        - if a filter is used and EG2 finishes before EG1, let the voice
1102          die when EG2 has finished (this fixes a problem with clicks and
1103          voice starvation for some gigs)
1104        - playback is no longer disabled during instrument loading
1105        - all notes playing on a channel that changes its instrument keep
1106          playing with the old instrument until they get a note off
1107          command
1108        - EG fix: a release value of zero could cause noises or crash
1109        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1110        - EG fine tuning: when attack is zero the EG starts at a level
1111          above max sustain level, which means that there is a decay phase
1112          even if sustain is 100%
1113        - more EG fixes: the level could sometimes go below zero and cause
1114          noises or crashes
1115        - minor fix of EGDecay (patch by Toshi Nagata)
1116        - fixed compiler error when --enable-override-filter-type was
1117          supplied to the configure script (fixes #46)
1118        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1119          instead of a fix value
1120        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1121          127 (solo mode) only kill voices if the respective mode really
1122          changed
1123    
1124      * LSCP server:
1125        - fixed compile time error for old Bison versions
1126          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1127        - parser now supports extended ASCII character set
1128          (up to ASCII code 255, i.e. includes now umlauts and accents)
1129        - filename arguments in LSCP commands now allow to use escape
1130          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1131          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1132          code value like \xf2) (fixes bug #24)
1133        - the following LSCP commands now also support escape sequences for at
1134          least one of their text-based parameters (i.e. name, description):
1135          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1136          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1137          "SET DB_INSTRUMENT_DIRECTORY NAME",
1138          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1139          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1140          "FIND DB_INSTRUMENT_DIRECTORIES"
1141        - returns verbose syntax errors (line and column where syntax error
1142          occured, the unexpected character and the actually expected, possible
1143          character(s), the latter only if less than 5 possibilities)
1144        - made sure that LSCP syntax is not affected by gigedit locale
1145          settings
1146        - bugfix regarding strings parameter lists: all comma separated lists
1147          of strings were treated as being one string containing commas
1148          (fixes #57)
1149    
1150      * Bug fixes:
1151        - fixed crash occurring on certain LSCP scripts (Bug 39)
1152        - another thread safety fix for lscp "load engine" and "set
1153          channel audio output device"
1154        - fixed a crash which occurs when reassigning the same engine
1155          on a sampler channel with connected MIDI device
1156        - fixed a crash which occurs when changing the number of ports of a MIDI
1157          device connected to a sampler channel to number less then or equal
1158          to the index of the port to which the sampler channel is connected.
1159        - The previous bindings were not been disconnected when altering
1160          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1161          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1162        - The active stream/voice count statistic was incorrect.
1163        - notification events were not been sent for some sampler
1164          channel changes
1165        - added default min and max values to restrict the number of allowed
1166          audio output channels and MIDI input ports
1167        - the connection to the PCM interface is now closed when destroying
1168          an audio output device
1169        - files with slash in their path or filename could not be loaded
1170    
1171      * test cases:
1172        - updated and fixed (haven't been touched in a while)
1173    
1174    Version 0.4.0 (24 November 2006)
1175    
1176      * packaging changes:
1177        - changed deprecated copyright attribute to license; added ldconfig
1178          to post-(un)install steps; added devel package for liblinuxsampler;
1179          to linuxsampler.spec (RPM)
1180        - install necessary development header files for allowing 3rd party
1181          applications to link against liblinuxsampler
1182        - liblinuxsampler's API documentation can be generated with 'make docs'
1183          (Doxygen required)
1184        - added benchmark to automatically detect the best triangle LFO
1185          implementation (currently either an integer math solution or a
1186          di-harmonic approximation), automatic detection can be overriden
1187          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1188          configure script argument though (mandatory for cross-compilation)
1189        - do not automatically pick optimized gcc flags if the user already
1190          provided some on his own (as CXXFLAGS)
1191        - added compile time option to disable processing of All-Notes-Off MIDI
1192          messages
1193        - added compile time options to allow disabling the various audio and
1194          MIDI drivers
1195        - fixed automatic GCC CPU switch detection on PPC
1196          (patch by Ebrahim Mayat)
1197    
1198      * Gigasampler format engine:
1199        - extensive synthesis optimization
1200          (reimplementation of EGs and LFO(s), removed synthesis parameter
1201          prerendering and the synthesis parameter matrix in general, splitting
1202          each audio fragment into subfragments now where each subfragment uses
1203          constant pitch and filter coefficients. The volume coefficient is
1204          linearly interpolated inside a subfragment, unless
1205          --disable-interpolate-volume is set.)
1206        - fine tuning of the EG modulation parameters
1207        - improved filter cutoff calculation by adding support for the
1208          following gig parameters: Cutoff freq (used when no cutoff
1209          controller is defined), Control invert, Minimum cutoff, Velocity
1210          curve and Velocity range. The keyboard tracking now scales
1211          cutoff frequency instead of resonance.
1212        - added support for gig parameter Resonance.
1213        - fixed bug in sysex handling (patch by Juan Linietsky)
1214        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1215          which can be overridden with --enable-global-attenuation
1216        - EG fixes: made the length of "attack hold" stage more
1217          accurate. Release stage can now start before attack stage
1218          ends. Cancel release didn't work when sustain was zero. Attack
1219          time now has a minimal value to prevent clicks.
1220        - fixed pitch changes larger than one octave
1221        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1222        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1223          all modes can be altered via standard GM messages, that is CC5 for
1224          altering portamento time, CC65 for enabling / disabling portamento
1225          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1226        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1227          parameter) and crossfade
1228        - added support for the "attenuation controller threshold" gig
1229          parameter
1230        - added smoothing of volume changes caused by control change
1231          messages
1232        - sample loop parameters are now taken from the DimensionRegion
1233          instead of the wave chunk
1234        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1235          not equal to a power of two
1236        - reimplementation of the filter algorithm. The new filter is more
1237          accurate and supports all gig filter types, including bandreject
1238          and lowpass turbo.
1239        - real support for 24 bit samples - samples are not truncated to
1240          16 bits anymore
1241        - support for aftertouch (channel pressure, not polyphonic
1242          aftertouch)
1243        - LFO1 behaviour fixed (dampening from max volume instead of
1244          amplifying from 0)
1245    
1246      * LSCP server:
1247        - fixed application exit on broken pipe error (fixes bug #20)
1248        - fixed the notification messages delay due to lack of
1249          network activity (fixes bug #26)
1250        - fixed parser bug which occured on space(s) within device parameters
1251          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1252    
1253      * audio driver:
1254        - added aRts audio output driver (by no means RT safe)
1255    
1256      * MIDI driver:
1257        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1258          messages several times instead of once
1259        - API extension for MIDI drivers which already supply exact time stamps
1260          for events (i.e. for offline rendering based MIDI drivers)
1261        - added checks for bad MIDI data
1262    
1263      * linuxsampler application:
1264        - show available sampler engine types on startup
1265    
1266      * general changes:
1267        - support for muting sampler channels and solo mode of the same, two new
1268          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1269          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1270          introduced for this, the behavior is the same like on a mixer console
1271          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1272          --enable-process-muted-channels which can be used to enable the
1273          processing of muted channels.
1274        - support for sostenuto pedal
1275        - support for monitoring the total number of active voices
1276          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1277          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1278        - fixed some memory management errors
1279        - fixed some concurrency problems that could lead to crashes when
1280          LSCP commands were executed
1281        - fixed crash when instrument loading failed previously on the same
1282          sampler channel (fixes bug #36)
1283    
1284    Version 0.3.3 (15 July 2005)
1285    
1286      * packaging changes:
1287        - fixed compilation with gcc 4.0
1288    
1289      * Gigasampler format engine:
1290        - LFO preprocessing was performed even though the respective LFO was
1291          disabled by the instrument patch (minor efficiency fix)
1292        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1293          for volume ramp downs in the same fragment (needed for current voice
1294          stealing implementation) then simply inform the user with a warning
1295          about possible click sounds and reduce the volume ramp down
1296          appropriately instead of cancelling the audio device connection
1297    
1298    Version 0.3.2 (24 June 2005)
1299    
1300    * packaging changes:    * packaging changes:
1301      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
# Line 15  Version CVS HEAD (?) Line 1312  Version CVS HEAD (?)
1312      - volume of release triggered samples now depends on note-on velocity,      - volume of release triggered samples now depends on note-on velocity,
1313        note length and gig parameter "release trigger decay" instead of        note length and gig parameter "release trigger decay" instead of

1315      - revised voice stealing (fixes crash caused by voice stealing)      - revised voice stealing
1316          (fixes crash and endless loop caused by voice stealing)
1317      - don't reset scale tuning on instrument or audio output device change      - don't reset scale tuning on instrument or audio output device change
1318        - handle key group conflicts right at the beginning of each fragment
1319          instead of when the respective voice is actually launched
1320          (fixes undefined behavior if stolen voices belonged to a key group -
1321          this case was followed by a "killed voice survived" error message)
1322        - fixed minor issue with null/silence samples
1323          (those stole voices even though they don't need a voice at all which
1324          resulted in "voice stealing didn't work out" messages)
1325        - don't reset volume, pan, pitch and MIDI controller values on
1326          instrument or audio output device change
1327

1330        - fixed LSCP event "CHANNEL_INFO" notification
1331          (e.g. did not notify on volume changes or MIDI program change events)
1332    
1333      * linuxsampler application:
1334        - added command line parameters --lscp-addr and --lscp-port to override
1335          default IP address and port of LSCP server
