# 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        - sfz parser: allow missing space between header and opcode
11    
12      * Gigasampler/GigaStudio format engine:
13        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14          cutoff settings.
15    
16      * general changes:
17        - fixed printf type errors (mostly in debug messages)
18        - use unique_ptr instead of auto_ptr when building with C++11
19        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
20          allowing to sort data efficiently in real-time safe manner.
21        - RTList class: added methods for moving/inserting elements to arbitrary
22          position within a list.
23        - RTList class: added method fromPtr() for creating an Iterator object from
24          a raw element pointer.
25        - Attempt to partly fix resetting engine channels vs. resetting engine, an
26          overall cleanup of the Reset*(), ConnectAudioDevice(),
27          DisconnectAudioDevice() API methods would still be desirable though,
28          because the current situation is still inconsistent and error prone.
29        - Active voices are now internally grouped to "Note" objects, instead of
30          being directly assigned to a keyboard key. This allows more fine graded
31          processing of voices, which is i.e. required for certain instrument
32          script features.
33        - Fix: Release trigger voices were not spawned on sustain pedal up
34          (CC #64) events.
35        - Fix: Release trigger voices can now also distinguish correctly between
36          note-off and sustain pedal up events.
37        - All engines: Increased ramp speed of volume smoother and pan smoother
38          (while slow rate of crossfade smoother is preserved) to allow quick
39          volume and pan changes by instrument scripts for instance.
40        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
41          properly and thus were ignored for certain uses.
42        - Added new C++ API method
43          VirtualMidiDevice::SendChannelPressureToSampler().
44        - windows, 32-bit: fixed potential crashes by making sure the stack in
45          sub threads is 16-byte aligned
46        - fixed numerous compiler warnings
47        - Fixed invalid (note-on) event ID being assigned to new Note objects.
48        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
49          fixes potential undefined behavior.
50    
51      * packaging changes:
52        - removed unnecessary dependency to libuuid
53          (originated by libgig's usage of it)
54        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
55          auto detect whether it (sh/c)ould output its messages in color.
56    
57      * Real-time instrument scripts:
58        - Implemented scheduler for delayed MIDI events and for suspended scripts.
59        - Built-in script function "wait()": implemented support for function's
60          "duration-us" argument, thus scripts using this function are now
61          correctly resumed after the requested amount of microseconds.
62        - Built-in script function "play_note()": implemented support for
63          function's "duration-us" argument, thus notes triggered with this
64          argument are now correctly released after the requested amount of
65          microseconds.
66        - Fix: script events were not cleared when engine channel was reset,
67          potentially causing undefined behavior.
68        - Fixed crash which happened when trying to reference an undeclared
69          variable.
70        - Built-in script function "play_note()": Added support for passing
71          special value -1 for "duration-us" argument, which will cause the
72          triggered note to be released once the original note was released.
73        - Instrument script classes now exported with the liblinuxsampler C++ API.
74        - Added new API method ScriptVM::syntaxHighlighting() which provides
75          a convenient syntax highlighting backend for external instrument
76          script editor applications.
77        - Added new C++ API class "ScriptVMFactory".
78        - Extended parser issues to provide not only first line and first
79          column, but also last line and last column of issue (thus marking
80          the precise span of the issue within the source code).
81        - Reload script automatically after being modified by an instrument
82          editor.
83        - NKSP language grammar correction: allow empty event handler bodies
84          like "on note end on".
85        - Implemented built-in script function "change_vol()".
86        - Implemented built-in script function "change_tune()".
87        - Implemented built-in script function "change_pan()".
88        - Implemented built-in script function "change_cutoff()".
89        - Implemented built-in script function "change_reso()".
90        - Implemented built-in script function "event_status()".
91        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
92          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
93          "event_status()" function.
94        - NKSP language: Added support for bitwise operators ".or.", ".and."
95          and ".not.".
96        - NKSP language scanner: Fixed IDs matching to require at least one
97          character (i.e. when matching function names or variable names).
98        - NKSP language scanner: disabled unusued rules.
99        - Fixed behavior of play_note() and note_off() functions which must
100          be distinguished engine internally from "real" MIDI note on/off
101          events in order to avoid misbehaviors like hanging notes.
102        - Implemented built-in script variable "$KSP_TIMER".
103        - Implemented built-in script variable "$NKSP_REAL_TIMER".
104        - Implemented built-in script variable "$NKSP_PERF_TIMER".
105        - Implemented built-in script variable "$ENGINE_UPTIME".
106        - Implemented built-in script function "inc()".
107        - Implemented built-in script function "dec()".
108        - NKSP language fix: division expressions were evaluated too often.
109        - NKSP language fix: string concatenation operator was right
110          associative instead of left (to right).
111        - NKSP language correction: allow empty statements in entire language
112          (i.e. "if end if").
113        - Implemented built-in script function "stop_wait()".
114        - Implemented built-in script variable "$NI_CALLBACK_ID".
115        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
116        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
117        - Added support for read-only built-in variables (respectively
118          handled by the script parser).
119        - Added built-in script constant "$NI_CB_TYPE_INIT".
120        - Added built-in script constant "$NI_CB_TYPE_NOTE".
121        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
122        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
123        - NKSP Language: Added support for user defined script functions.
124        - Implemented built-in script function "change_attack()".
125        - Implemented built-in script function "change_decay()".
126        - Implemented built-in script function "change_release()".
127        - Fixed all change_*() built-in script functions to apply their
128          synthesis parameter changes immediately in case the respective note
129          was triggered at the same time, instead of scheduling the parameter
130          change, especially because it would cause some parameter types's
131          changes either to be ramped (i.e. change_vol()) or other types even
132          to have not effect at all (i.e. change_attack()).
133        - Implemented built-in script function "sh_left()".
134        - Implemented built-in script function "sh_right()".
135        - Implemented built-in script function "min()".
136        - Implemented built-in script function "max()".
137        - NKSP Fix: "init" event handler was not always executed when a script
138          was loaded.
139        - NKSP built-in wait() script function: abort script execution if
140          a negative or zero wait time was passed as argument (since this is
141          a common indication of a bug either of the script or even of the
142          engine, which could lead to RT instability or even worse).
143        - ScriptVM: Implemented automatic suspension of RT safety
144          threatening scripts.
145        - Provide more user friendly error messages on syntax errors.
146        - Fixed NKSP parser warning "Not a statement" when assigning an
147          initializer list to an array variable.
148        - Implemented built-in script array variable "%ALL_EVENTS".
149        - Implemented built-in script function "in_range()".
150        - Implemented built-in script function "change_amp_lfo_depth()".
151        - Implemented built-in script function "change_amp_lfo_freq()".
152        - Implemented built-in script function "change_pitch_lfo_depth()".
153        - Implemented built-in script function "change_pitch_lfo_freq()".
154        - Implemented built-in script function "change_vol_time()".
155        - Implemented built-in script function "change_tune_time()".
156        - Implemented built-in script function "fade_in()".
157        - Implemented built-in script function "fade_out()".
158        - Fixed acceptance of wrong data type of parameters passed to built-in
159          script functions "change_vol()", "change_tune()", "change_pan()",
160          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
161          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
162          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
163        - Added built-in script function "get_event_par()" and implemented some
164          of its possible parameter selections.
165        - Added built-in script function "set_event_par()" and implemented some
166          of its possible parameter selections.
167        - Fixed a bunch of scheduler time related bugs.
168        - Fixed polyphonic variables not being reset to zero after usage.
169        - Built-in "ignore_event()" function: argument is now optional, like with
170          built-in function "ignore_controller()".
171        - Implemented built-in script function "change_velo()".
172        - Implemented built-in script function "change_note()".
173        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
174          intuitive behavior if used in combination with "change_vol_time()" or
175          "change_tune_time()" respectively: now tuning/volume changes are only
176          assigned (without delay) immediately to a new note if the respective
177          timing function has not been called before, otherwise the volume/tuning
178          changes are automatically faded (before, only the event's time stamp was
179          relevant).
180         - Implemented built-in script function "array_equal()".
181         - Implemented built-in script function "search()".
182         - Implemented built-in script function "sort()".
183         - NKSP Fix: Never suspend "init" event handlers.
184         - Implemented built-in script function "same_region()" (currently only
185           available for gig format engine).
186         - Added built-in script constant "$NKSP_LINEAR".
187         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
188         - Implemented built-in script function "change_vol_curve()".
189         - Implemented built-in script function "change_tune_curve()".
190         - built-in "play_note()" function now supports a sample playback start
191           offset with argument 3, where special value -1 means to use the regular
192           sample offset as defined by the instrument file.
193         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
194         - Built-in variable $EVENT_NOTE is now a read-only variable.
195         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
196         - built-in "play_note()" function now accepts -2 for its fourth argument
197           (note duration) which means the life time of the note shall be sticked
198           to the requested note number of argument 1.
199         - Fix: built-in "play_note()" function now returns 0 as result value if
200           -1 was passed for its fourth argument (note duration) and the respective
201           parent note is already gone.
202        - Implemented built-in script function "change_play_pos()".
203        - NKSP language: Added support for user declared const array variables.
204        - NKSP language: Raise parser warning if array variable is accessed with
205          an index that exceeds the array's size.
206        - NKSP language fix: Unknown characters were not handled correctly.
207        - NKSP language: Added support for "synchronized .. end synchronized"
208          code blocks.
209        - Implemented built-in script function "abort()" which allows to abort
210          another script handler by passing its callback ID.
211        - Fixed potential memory access bug and potential undefined behavior of
212          "init" event handlers.
213        - Print a time stamp along to each call of built-in function "message()".
214        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
215          to retrieve all code blocks filtered out by the preprocessor.
216    
217      * Instruments DB:
218        - Fixed memory access bug of general DB access code which lead to
219          undefined behavior.
220        - Cleanup of instruments DB file creation and opening code.
221        - The instrument DB path of linuxsampler's --create-instruments-db argument
222          is now optional, if it is missing, then a default location is used.
223        - Added support for scanning SFZ (.sfz) files.
224        - Added support for scanning Sound Font (.sf2) files.
225        - Fixed undefined DB transaction behavior.
226    
227    Version 2.0.0 (15 July 2015)

229      * packaging changes:
230        - fixed building with newer MinGW-w64
231        - Mac OS X: support the new dir for Core Audio SDK
232        - Mac OS X: fixed building outside source directory
233        - made sure all source files for hostplugins are included when
234          doing "make dist"
235        - removed empty directories left from the cvs to svn migration
236        - fixed compilation with gcc 4.6.1
237        - another "make dist" fix, for the LV2 plugin
238        - made --enable-pthread-testcancel default on Mac OS X
239        - minor Makefile fix for building lscpparser when build and source
240          directories are separate
241        - Mac OS X: made it possible to specify plugin installation dir to
242          configure
243        - Mac OS X: Makefile fix for the install-strip target
244        - fixed compilation with gcc 4.7
245        - fixed configure script error with old autoconf versions
246        - lsatomic.h: use gcc provided atomic functions if building with
247          gcc 4.7 and C++11
248        - modernized configure script
249        - fixed linkage error when building with
250          LDFLAGS="-Wl,--no-undefined" (#190)
251        - fixed compilation with Clang 3.2
252        - removed usage of deprecated Automake variable INCLUDES

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

698        - Giga format scripts: Implemented built-in script function
699          "gig_set_dim_zone(event_id, dimension, zone)".
700        - Implemented built-in script int array variable %KEY_DOWN.
701        - Implemented built-in script function "abs()".
702        - Implemented built-in script function "random()".
703        - Implemented built-in script function "num_elements()".
704        - Implemented built-in script function "note_off()".
705        - Implemented built-in script function "set_event_mark()".
706        - Implemented built-in script function "delete_event_mark()".
707        - Implemented built-in script function "by_marks()".
708        - Added built-in script int const variables $MARK_1 to $MARK_28.
709        - Built-in script functions "ignore_event()", "note_off()" and
710          "gig_set_dim_zone()" now also accept an array of event IDs as argument
711          (i.e. return value of new script function "by_marks()").
712        - Pass/preserve polyphonic variable data from respective "note" event
713          handler to "release" event handler.
714        - Fixed crash when using built-in script function "by_marks()".
715    
716      * Bug fixes:
717        - Fixed crash which may occur when MIDI key + transpose is out of range
718        - minor valgrind fixes
719        - fixed crash which occurred when changing an already deployed sampler
720          channel to a different engine type
721        - fixed crash when deleting a sampler channel or changing engine
722          type while an instrument load was in progress
723        - bugfix: playing a note while changing the instrument could cause
724          a crash, or give "Handing back unknown region" error messages
725        - bugfix: calling SET VOICES (which Fantasia does on start and
726          refresh) could cause instruments to be unloaded
727        - Mac OS X: fixed name collision of enum in EffectControl and
728          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
729        - Mac OS X: fixed hanging threads
730        - Windows: disabled the previous thread fix on non-Mac systems, as
731          it caused hanging threads on Windows
732        - Fixed possible crashes due to corrupted MIDI/audio device list
733          after MIDI/audio device creation failure
734        - When creating MIDI instrument map entries with "PERSISTENT" type, the
735          instruments were uselessly precached with zero samples, however it still
736          took the full preloading time and on 1st program change the respective
737          instrument was completely reloaded again.
738        - fixed handling of rapid bank select and program change messages
739          sent to the same sampler channel (patch from the Open Octave
740          project, slightly adjusted)
741        - fixed crash when trying to create an effect instance with controls
742          which min and/or max values depend on the sample rate
743        - fixed bug #162
744        - bugfix: LADSPA_PATH was not evaluated correctly when containing
745          multiple paths (#165)
746        - thread safety fixes for the instrument loading thread
747        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
748          (#176)
749        - more thread safety fixes for the instrument loading thread
750        - sfz/sf2 engine: fixed crash when using small audio fragment size
751        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
752        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
753          introduced in previous fix)
754        - fixed crash when a channel received a program change while
755          playing a note in a key group
756        - fixed erroneous error message piping in VoiceBase.h
757          (labelled "Disk stream not available in time")
758        - Update effects on sample rate & period size changes (to avoid
759          crashes and noise on such transitions).
760        - ignore missing LADSPA paths without ignoring valid LADSPA paths
761          (fixes #208)
762        - Fixed bug in LSCP grammar definition which caused a statement like
763          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
764          practically irrelevant, however it caused problems with the new LSCP
765          shell's auto completion feature).
766        - Fixed MIDI program change messages being ignored if quickly executed
767          after each other (fixes #231).
768    
769    Version 1.0.0 (31 July 2009)
770    
771      * packaging changes:
772        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
773          causing e.g. the libgig test to fail when
774          "./configure --disable-jack-driver" was used
775          (patch by Alexis Ballier)
776        - fixed compilation with gcc 4.3
777        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
778        - fixed configure so it detects x86_64 (#107)
779        - fixes for building with newer MinGW versions
780        - fix for building with bison 2.4 (#111)
781        - fixed building with libgig installed in a non-standard directory
782        - minor fix in configure for mmsystem.h detection on MinGW
783        - Windows: look for editor plugins and Fantasia using base
784          directory of liblinuxsampler dll (look in the same directory and one
785          directory above)
786        - configure script fix: removed unconditional use of SSE
787        - fixed building with sqlite installed in a non-standard directory
788        - when cross-compiling, don't try to create instruments.db
789        - fix for new mingw-w64 version, which has usleep
790    
791      * general changes:
792        - bugfix: on some POSIX systems instrument editor plugins refused to
793          load as we used a non-portable Linux specific struct field
794          (fixes bug #70, patch by Ronald Baljeu)
795        - fixed endless loop which occured when loading an instrument editor
796          plugin DLL on Windows systems failed
797        - fixed memory leaks that occurred when liblinuxsampler was unloaded
798        - optimized the SynchronizedConfig class so it doesn't wait
799          unnecessarily long after an update
800        - added support for notifying instrument editors on note-on / note-off
801          events (e.g. to highlight the pressed keys on the virtual keyboard
802          of gigedit)
803        - added support for triggering notes by instrument editors (see above)
804        - be verbose on DLL load errors (on Linux)
805        - fixed di-harmonic triangle LFO implementation (this LFO implementation
806          is only used by very few systems, most pick the int math
807          implementation, which is usually faster)
808        - fixes for audio drivers with varying buffer sizes
809        - experimental support for running LinuxSampler as a DSSI, LV2 and
810          VST plugin
811        - notification events for stream/voice count statistics are now sent
812          only when there are actual changes
813        - added memory ordering constraints to improve stability on
814          multi-core and multi-cpu systems
815        - maximum voices and disk streams can now be altered at runtime
816        - fixed CPU feature detection on x86_64 (maybe fixes #108)
817        - automatic stacktrace mechanism is now turned off by default and can
818          be switched on by command line option "--stacktrace" (the automatic
819          stacktrace mechanism seems to be broken on most systems at the moment)
820        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
821          a pointer to the launched InstrumentEditor object
822        - added optional 3rd party user data parameter for following
823          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
824          InstrumentEditor::Launch(),
825          InstrumentManager::LaunchInstrumentEditor()
826        - theoretical fix: made SynchronizedConfig follow C++0x memory
827          model more strictly
828        - fixes for using large audio device buffers
829        - Windows: add the installation directory to the DLL search path
830          when loading an editor plugin (solves problems with VST and
831          gigedit on systems with other GTK versions installed)
832        - updated linuxsampler man page
833    
834      * audio driver:
835        - removed the nonsense audio channel constraint (which was hard coded to
836          max. 100 audio channels) for most audio drivers
837        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
838          opposed to the LSCP specs
839        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
840          reflected the wrong value
841        - fixed a memory management bug in ASIO driver
842        - Makefile fix: JACK_CFLAGS wasn't used
843        - JACK: use jack_client_open instead of the deprecated
844          jack_client_new
845        - added (experimental) CoreAudio driver
846        - applied old fixes to the ASIO driver that were included in the
847          previous binary release but accidentally never committed to CVS
848          (fixes #117)
849        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
850          win64)
851        - VST: added support for sample rate and buffer size changes
852        - VST: close editor (Fantasia) when the VST is removed
853        - VST: avoid opening Fantasia more than once for each VST instance
854        - VST: export main function as "main" on Linux too (fix for
855          energyXT)
856        - VST: changed number of output channels from one stereo to 16
857          stereo
858        - added channel routing, fxsends and midi maps to the settings
859          stored in the plugin state
860        - performance optimization of AudioChannel::MixTo() and
861          AudioChannel::CopyTo() methods using GCC vector exensions
862          (if available)
863        - ASIO fixes: avoid initializing the device twice, avoid throwing
864          exception when getting parameters from a disconnected device
865    
866      * MIDI driver:
867        - added JACK MIDI driver
868        - dispatch bank select as ordinary CC as well, the user might seriously
869          want to (mis)use it for some purpose ("fixed" in all current MIDI
870          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
871        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
872          CoreMidi or AU
873        - fixed mingw-w64 compilation error in MME driver
874        - made program change handling in MIDI thread real-time safe by
875          moving the logic to a non-RT thread
876        - fixed minor memory leak in ALSA driver
877    
878      * instruments database:
879        - avoid time consuming samples scanning when adding instruments
880          to the instruments database
881        - added support for handling lost files in the instruments database
882        - Implemented option for adding instruments in separate directories
883          in the instruments database
884          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
885        - work-around for missing fnmatch function on Windows to make
886          instrument database compilable
887        - added instrument database support on Windows
888          works with both standalone mode and VST plugin.
889          the instruments DB file is located in
890          %USERPROFILE%\.linuxsampler\instruments.db which allows different
891          databases for each windows user
892          if no DB is present it automatically creates the .linuxsampler subdir
893          and then creates an empty DB
894        - fixed recursive import, which was broken on Windows
895    
896      * Gigasampler format engine:
897        - fixed a memory leak that could happen when a channel was deleted
898          while notes were playing
899        - made it possible to load an instrument even if the audio thread
900          isn't running
901        - added partial support for the "Controller Triggered" MIDI rule,
902          enough for piano gigs with pedal noise samples
903        - minor fix: only mark FX sends as being modified if really the
904          respective FX send MIDI controller was used
905        - added support for GM global device volume SysEx message
906          (can be selected at compile time to either apply globally to the
907          whole sampler [default] or only to the sampler channels that are
908          connected to the respective MIDI input port the SysEx message arrived
909          on)
910        - bugfix: notes triggered at position 0 in the audio buffer were
911          sometimes wrongly killed in the same buffer, causing no sound to
912          be played
913        - added support for chromatic / drumkit mode Roland GS Sysex message
914          which is usally used to switch a part between chromatic sounds and
915          drumkit sounds (as opposed to their common default setting of MIDI
916          part 10 being a drumkit part and all other ones chromatic parts), in
917          LS however one can switch between the first 16 MIDI instrument maps
918          defined for the sampler
919        - made it possible to create multiple sample channels even if the
920          audio thread isn't running
921        - fixed crash when removing channel with active voices (#116)
922        - bugfix: on sample reference changes (instrument editor), only
923          un-cache the respective sample if it's really not used by any
924          sampler engine anymore
925        - re-cache samples in case they were changed by an instrument editor,
926          e.g. when a sample was added while playing (#82)
927        - fixed hanging notes which occured when note-off event had the exact
928          same time stamp as the voice's note-on event and occured both in the
929          same audio fragment cycle (fixes bug #112)
930        - added support for the "fine tune" and "pitch bend range"
931          instrument-level gig parameters
932        - fixed minor artifacts in pitch bend handling
933        - added support for GS Reset SysEx message
934        - allow gig files to use unlimited downward pitch shifting
935        - added a limit check for upward pitch shifting
936        - bugfix: sometimes, when playing a note twice fast, the second
937          note was silent
938        - fixed crash happening when a pitch bend event arrived at the
939          same time a new instrument was loading
940    
941      * LSCP server:
942        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
943          react on MIDI data arriving on certain sampler channels (so far only
944          Note-On and Note-Off events are sent via this LSCP event)
945        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
946          react on MIDI data arriving on certain MIDI input devices (so far only
947          Note-On and Note-Off events are sent via this LSCP event)
948        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
949          SET DB_INSTRUMENT FILE_PATH
950        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
951          frontends to send MIDI messages to specific sampler channel
952        - added two additional fields to GET FILE INSTRUMENT INFO command -
953          KEY_BINDINGS and KEYSWITCH_BINDINGS
954        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
955          was incorrect
956        - Optimized the retrieval of the MIDI instrument mappings
957        - added new LSCP command "SET VOICES" to globally alter the maximum
958          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
959          be triggered respectively
960        - added new LSCP command "SET STREAMS" to globally alter the maximum
961          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
962          which will be triggered respectively
963        - bugfix: retry if "select" returns EINTR (this fixes a crash when
964          a gigedit file dialog is opened)
965        - close all connections when LSCPServer is deleted
966        - hard close of all sockets on exit
967        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
968          driver
969    
970      * Bug fixes:
971        - fixed a crash which occurs when removing a sampler channel waiting
972          to start instrument loading after another channel
973        - fixed a crash which occurs when removing a sampler channel with
974          instrument loading in progress (bug #113)
975        - fixed termination caused by uncaught exception when adding MIDI
976          instrument with PERSISTENT load mode
977        - fixed possible iterator invalidations when resetting the sampler
978        - fixed memory leaks when issuing the following LSCP commands:
979          GET AUDIO_OUTPUT_DRIVER INFO
980          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
981          GET MIDI_INPUT_DRIVER INFO
982          GET MIDI_INPUT_DRIVER_PARAMETER INFO
983        - fixed possible compilation error when sqlite is not present
984        - fixed orphaned pointers when setting maximum voices limit (bug #118)
985        - fixed crash when changing the audio output device of a sampler
986          channel with loaded instrument and start playing notes
987        - fixed endless loop in Engine::SuspendAll() (bug #120)
988        - fixed a low-level atomic load function that was broken on 64-bit
989          PowerPC, which probably could cause crashes on that platform
990        - fixed a memory management error which could cause a crash when a
991          plugin was unloaded
992        - bugfix: two private structs had the same name, which could cause
993          problems if the linker chose the wrong constructor
994        - fixed low-level ConditionServer usage bug that caused lockups on
995          Windows
996    
997    
998    Version 0.5.1 (6 December 2007)
999    
1000      * packaging changes:
1001        - added autoconf checks for pthread library
1002        - added autoconf check for pthread bug found on certain NPTL-enabled
1003          glibc versions (see Gentoo bug report #194076)
1004        - added autoconf checks for MS Windows
1005    
1006      * general changes:
1007        - bugfix: the thread used by an editor plugin didn't die when the
1008          editor closed
1009        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1010          out all the space. operator--() did not apply size_mask after
1011          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1012          order to avoid problems with the _NonVolatileReader functions.
1013        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1014          GetWriteSpace(). Since this function is currently only used in
1015          the stream's qsort() compare function, it didn't trigger any
1016          bugs.
1017        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1018          24bit mode too. Faster method to read 24bit words on little
1019          endian machines (x86): replaced 3 byte reads + shifts with a 1
1020          unaligned 32bit read and shift
1021        - experimental support for MS Windows (MIDI input via MME, AUDIO
1022          output via ASIO)
1023        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1024        - support for monitoring the total number of active disk streams
1025          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1026          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1027    
1028      * AUDIO driver:
1029        - added Windows ASIO low latency audio driver
1030    
1031      * MIDI driver:
1032        - added MME Windows MIDI driver
1033    
1034      * LSCP server:
1035        - added support for Windows style path / filenames, however with
1036          forward slash path separators instead of backslash
1037          (i.e. "C:/foo/bar.gig")
1038        - allow naughty liblscp to send non-string device parameters within
1039          apostrophes as well
1040        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1041          "LIST FILE INSTRUMENTS <file>" and
1042          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1043          about an arbitrary instrument file on the system where the sampler is
1044          running on
1045    
1046    Version 0.5.0 (15 October 2007)
1047    
1048      * packaging changes:
1049        - config.h is not going to be installed along with liblinuxsampler's
1050          API header files anymore
1051        - only the API relevant header (and source) files will be exported to
1052          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1053        - added completely new XCode project files for Mac OSX which is now
1054          capable to execute our autoconf environment, thus no need anymore
1055          to maintain the compile time configuration file (osx/version.h) for
1056          OSX manually (patch by Toshi Nagata)
1057        - fixed buggy boolean --enable-foo / --disable-foo configure script
1058          parameters
1059        - global.h now only covers global definitions that are needed for the
1060          C++ API header files, all implementation internal global definitions
1061          are now in global_private.h
1062        - atomic.h is not exposed to the C++ API anymore
1063        - no need to include config.h anymore for using LS's API header files
1064        - fixed warnings in API doc generation
1065    
1066      * general changes:
1067        - replaced the old, confusing MIDI program change mechanism by a
1068          flexible MIDI instrument mapper which allows to map arbitrary
1069          (MIDI bank, MIDI program) pairs with arbitrary
1070          (engine type, instrument file, file index) triplets which will be
1071          loaded on the respective channel when such MIDI program change
1072          messages arrive, beside that, each entry allows to define a life-time
1073          strategy for the instrument, so the user can define whether the
1074          instrument should i.e. be permanently loaded (to be able to switch
1075          quickly among sounds) or i.e. loaded just on demand when the
1076          respective program change arrives (to safe RAM space), as well as a
1077          global volume factor for each entry, so the user can adjust the volume
1078          dynamic of his mapped instrument collection without having to modify
1079          the instrument files, also one can manage arbitrary amount of such
1080          MIDI instrument maps and assign each sampler channel individually
1081          a certain map, so that i.e. separation of normal instruments and
1082          drumkits is possible
1083        - new notification events for tracking changes to audio/MIDI devices,
1084          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1085        - sampler was limited to load max. 200 instruments in the background
1086          due to a constant size RingBuffer FIFO which is now replaced by a
1087          dynamic (unlimited) size std::list FIFO
1088        - added FX sends, these allow to route audio signals to arbitrary audio
1089          output channels for being processed by external effect processors
1090          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1091          controllers
1092        - global (sampler wide) volume can now be controlled at runtime
1093        - Implemented new, improved notification system
1094        - fixed compilation errors regarding OSX
1095          (patch by Toshi Nagata)
1096        - implemented instruments database
1097        - added support for escape sequences to the instruments database
1098        - added highly experimental support for on-the-fly instrument editing
1099          within the sampler's process (by using instrument editor plugins),
1100          you'll notice the new "Registered instrument editors:" message on
1101          startup, added a new LSCP command:
1102          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1103          to spawn a matching instrument editor for the instrument on the
1104          given sampler channel, the plugin path can be overridden at compile
1105          time with ./configure --enable-plugin-dir=/some/dir
1106        - added experimental code for synchronizing instrument editors hosted
1107          in the sampler's process to safely edit instruments while playing
1108          without a crash (hopefully) by either suspending single regions
1109          wherever possible or if unavoidable whole engine(s)
1110        - fixed several issues in fundamental "Thread" class: set scheduling
1111          policy and priority on thread level, set a minimum stack size for
1112          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1113          threads simply inherited properties of starting thread instead of
1114          setting their own policy and priority
1115        - minor fix in our automatic stack trace mechanism on crashes, the
1116          main process did not wait for the stack trace process to finish
1117          its output
1118        - fixed some minor memory leaks
1119        - reenabled assembly features support, at the moment only for
1120          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1121        - minor assembly fix in x86 features detection (don't use the PIC
1122          register, to avoid relocations in the text segment at runtime)
1123        - POSIX callback functions of Thread.h are hidden
1124    
1125      * MIDI driver:
1126        - dispatch bank select (MSB and LSB) messages
1127    
1128      * audio driver:
1129        - the ALSA audio output driver parameters now reflect the correct
1130          parameter value ranges for the respective selected sound card
1131          (patch by Till Wimmer, a bit fixed and extended)
1132    
1133      * Gigasampler format engine:
1134        - if a filter is used and EG2 finishes before EG1, let the voice
1135          die when EG2 has finished (this fixes a problem with clicks and
1136          voice starvation for some gigs)
1137        - playback is no longer disabled during instrument loading
1138        - all notes playing on a channel that changes its instrument keep
1139          playing with the old instrument until they get a note off
1140          command
1141        - EG fix: a release value of zero could cause noises or crash
1142        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1143        - EG fine tuning: when attack is zero the EG starts at a level
1144          above max sustain level, which means that there is a decay phase
1145          even if sustain is 100%
1146        - more EG fixes: the level could sometimes go below zero and cause
1147          noises or crashes
1148        - minor fix of EGDecay (patch by Toshi Nagata)
1149        - fixed compiler error when --enable-override-filter-type was
1150          supplied to the configure script (fixes #46)
1151        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1152          instead of a fix value
1153        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1154          127 (solo mode) only kill voices if the respective mode really
1155          changed
1156    
1157      * LSCP server:
1158        - fixed compile time error for old Bison versions
1159          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1160        - parser now supports extended ASCII character set
1161          (up to ASCII code 255, i.e. includes now umlauts and accents)
1162        - filename arguments in LSCP commands now allow to use escape
1163          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1164          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1165          code value like \xf2) (fixes bug #24)
1166        - the following LSCP commands now also support escape sequences for at
1167          least one of their text-based parameters (i.e. name, description):
1168          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1169          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1170          "SET DB_INSTRUMENT_DIRECTORY NAME",
1171          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1172          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1173          "FIND DB_INSTRUMENT_DIRECTORIES"
1174        - returns verbose syntax errors (line and column where syntax error
1175          occured, the unexpected character and the actually expected, possible
1176          character(s), the latter only if less than 5 possibilities)
1177        - made sure that LSCP syntax is not affected by gigedit locale
1178          settings
1179        - bugfix regarding strings parameter lists: all comma separated lists
1180          of strings were treated as being one string containing commas
1181          (fixes #57)
1182    
1183      * Bug fixes:
1184        - fixed crash occurring on certain LSCP scripts (Bug 39)
1185        - another thread safety fix for lscp "load engine" and "set
1186          channel audio output device"
1187        - fixed a crash which occurs when reassigning the same engine
1188          on a sampler channel with connected MIDI device
1189        - fixed a crash which occurs when changing the number of ports of a MIDI
1190          device connected to a sampler channel to number less then or equal
1191          to the index of the port to which the sampler channel is connected.
1192        - The previous bindings were not been disconnected when altering
1193          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1194          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1195        - The active stream/voice count statistic was incorrect.
1196        - notification events were not been sent for some sampler
1197          channel changes
1198        - added default min and max values to restrict the number of allowed
1199          audio output channels and MIDI input ports
1200        - the connection to the PCM interface is now closed when destroying
1201          an audio output device
1202        - files with slash in their path or filename could not be loaded
1203    
1204      * test cases:
1205        - updated and fixed (haven't been touched in a while)
1206    
1207    Version 0.4.0 (24 November 2006)
1208    
1209      * packaging changes:
1210        - changed deprecated copyright attribute to license; added ldconfig
1211          to post-(un)install steps; added devel package for liblinuxsampler;
1212          to linuxsampler.spec (RPM)
1213        - install necessary development header files for allowing 3rd party
1214          applications to link against liblinuxsampler
1215        - liblinuxsampler's API documentation can be generated with 'make docs'
1216          (Doxygen required)
1217        - added benchmark to automatically detect the best triangle LFO
1218          implementation (currently either an integer math solution or a
1219          di-harmonic approximation), automatic detection can be overriden
1220          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1221          configure script argument though (mandatory for cross-compilation)
1222        - do not automatically pick optimized gcc flags if the user already
1223          provided some on his own (as CXXFLAGS)
1224        - added compile time option to disable processing of All-Notes-Off MIDI
1225          messages
1226        - added compile time options to allow disabling the various audio and
1227          MIDI drivers
1228        - fixed automatic GCC CPU switch detection on PPC
1229          (patch by Ebrahim Mayat)
1230    
1231      * Gigasampler format engine:
1232        - extensive synthesis optimization
1233          (reimplementation of EGs and LFO(s), removed synthesis parameter
1234          prerendering and the synthesis parameter matrix in general, splitting
1235          each audio fragment into subfragments now where each subfragment uses
1236          constant pitch and filter coefficients. The volume coefficient is
1237          linearly interpolated inside a subfragment, unless
1238          --disable-interpolate-volume is set.)
1239        - fine tuning of the EG modulation parameters
1240        - improved filter cutoff calculation by adding support for the
1241          following gig parameters: Cutoff freq (used when no cutoff
1242          controller is defined), Control invert, Minimum cutoff, Velocity
1243          curve and Velocity range. The keyboard tracking now scales
1244          cutoff frequency instead of resonance.
1245        - added support for gig parameter Resonance.
1246        - fixed bug in sysex handling (patch by Juan Linietsky)
1247        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1248          which can be overridden with --enable-global-attenuation
1249        - EG fixes: made the length of "attack hold" stage more
1250          accurate. Release stage can now start before attack stage
1251          ends. Cancel release didn't work when sustain was zero. Attack
1252          time now has a minimal value to prevent clicks.
1253        - fixed pitch changes larger than one octave
1254        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1255        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1256          all modes can be altered via standard GM messages, that is CC5 for
1257          altering portamento time, CC65 for enabling / disabling portamento
1258          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1259        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1260          parameter) and crossfade
1261        - added support for the "attenuation controller threshold" gig
1262          parameter
1263        - added smoothing of volume changes caused by control change
1264          messages
1265        - sample loop parameters are now taken from the DimensionRegion
1266          instead of the wave chunk
1267        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1268          not equal to a power of two
1269        - reimplementation of the filter algorithm. The new filter is more
1270          accurate and supports all gig filter types, including bandreject
1271          and lowpass turbo.
1272        - real support for 24 bit samples - samples are not truncated to
1273          16 bits anymore
1274        - support for aftertouch (channel pressure, not polyphonic
1275          aftertouch)
1276        - LFO1 behaviour fixed (dampening from max volume instead of
1277          amplifying from 0)
1278    
1279      * LSCP server:
1280        - fixed application exit on broken pipe error (fixes bug #20)
1281        - fixed the notification messages delay due to lack of
1282          network activity (fixes bug #26)
1283        - fixed parser bug which occured on space(s) within device parameters
1284          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1285    
1286      * audio driver:
1287        - added aRts audio output driver (by no means RT safe)
1288    
1289      * MIDI driver:
1290        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1291          messages several times instead of once
1292        - API extension for MIDI drivers which already supply exact time stamps
1293          for events (i.e. for offline rendering based MIDI drivers)
1294        - added checks for bad MIDI data
1295    
1296      * linuxsampler application:
1297        - show available sampler engine types on startup
1298    
1299      * general changes:
1300        - support for muting sampler channels and solo mode of the same, two new
1301          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1302          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1303          introduced for this, the behavior is the same like on a mixer console
1304          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1305          --enable-process-muted-channels which can be used to enable the
1306          processing of muted channels.
1307        - support for sostenuto pedal
1308        - support for monitoring the total number of active voices
1309          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1310          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1311        - fixed some memory management errors
1312        - fixed some concurrency problems that could lead to crashes when
1313          LSCP commands were executed
1314        - fixed crash when instrument loading failed previously on the same
1315          sampler channel (fixes bug #36)
1316    
1317    Version 0.3.3 (15 July 2005)
1318    
1319      * packaging changes:
1320        - fixed compilation with gcc 4.0
1321    
1322      * Gigasampler format engine:
1323        - LFO preprocessing was performed even though the respective LFO was
1324          disabled by the instrument patch (minor efficiency fix)
1325        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1326          for volume ramp downs in the same fragment (needed for current voice
1327          stealing implementation) then simply inform the user with a warning
1328          about possible click sounds and reduce the volume ramp down
1329          appropriately instead of cancelling the audio device connection
1330    
1331    Version 0.3.2 (24 June 2005)
1332    
1333    * packaging changes:    * packaging changes:
