* NKSP language fix: Unknown characters were not handled correctly.
* Bumped version (2.0.0.svn59).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5 schoenebeck 3082 - 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 schoenebeck 3095 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 schoenebeck 3100 - Fixed unintended volume fade-in of voices under certain conditions.
10 persson 2856
11 schoenebeck 3188 * Gigasampler/GigaStudio format engine:
12 schoenebeck 3072 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13     cutoff settings.
14    
15 persson 2837 * general changes:
16     - fixed printf type errors (mostly in debug messages)
17 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
18 schoenebeck 2871 - 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 schoenebeck 2879 - 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 schoenebeck 2927 - 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 schoenebeck 2963 - 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 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40     properly and thus were ignored for certain uses.
41 schoenebeck 3018 - Added new C++ API method
42     VirtualMidiDevice::SendChannelPressureToSampler().
43 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
44     sub threads is 16-byte aligned
45 schoenebeck 3054 - fixed numerous compiler warnings
46 schoenebeck 3205 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47 persson 2837
48 schoenebeck 2866 * packaging changes:
49     - removed unnecessary dependency to libuuid
50     (originated by libgig's usage of it)
51 schoenebeck 2884 - 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 schoenebeck 2866
54 schoenebeck 2871 * 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 schoenebeck 2879 - 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 schoenebeck 2885 - 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 schoenebeck 2889 - 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 schoenebeck 2902 - Reload script automatically after being modified by an instrument
79     editor.
80 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
81     like "on note end on".

83     - Implemented built-in script function "change_tune()".
84     - Implemented built-in script function "change_pan()".
85 schoenebeck 2935 - 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 schoenebeck 2938 - 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 schoenebeck 2942 - 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 schoenebeck 2945 - 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 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
109     (i.e. "if end if").
110 schoenebeck 2948 - 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).

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".

121 schoenebeck 2953 - Implemented built-in script function "change_attack()".
122     - Implemented built-in script function "change_decay()".
123     - Implemented built-in script function "change_release()".
124 schoenebeck 2962 - 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 schoenebeck 2965 - Implemented built-in script function "sh_left()".
131     - Implemented built-in script function "sh_right()".
132 schoenebeck 2970 - Implemented built-in script function "min()".
133     - Implemented built-in script function "max()".
134 schoenebeck 2972 - 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 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
141     threatening scripts.
142 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
143 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
144     initializer list to an array variable.
145 schoenebeck 3073 - Implemented built-in script array variable "%ALL_EVENTS".
146 schoenebeck 3076 - Implemented built-in script function "in_range()".
147 schoenebeck 3118 - 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 schoenebeck 3188 - 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 schoenebeck 3193 - 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 schoenebeck 3205 - Fixed a bunch of scheduler time related bugs.
165 schoenebeck 3207 - Fixed polyphonic variables not being reset to zero after usage.
166 schoenebeck 3212 - Built-in "ignore_event()" function: argument is now optional, like with
167     built-in function "ignore_controller()".
168 schoenebeck 3214 - Implemented built-in script function "change_velo()".
169     - Implemented built-in script function "change_note()".
170 schoenebeck 3218 - 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 schoenebeck 3221 - 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 schoenebeck 3228 - Implemented built-in script function "same_region()" (currently only
182     available for gig format engine).
183 schoenebeck 3246 - Added built-in script constant "$NKSP_LINEAR".
184     - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185     - Implemented built-in script function "change_vol_curve()".
186     - Implemented built-in script function "change_tune_curve()".
187 schoenebeck 3251 - built-in "play_note()" function now supports a sample playback start
188     offset with argument 3, where special value -1 means to use the regular
189     sample offset as defined by the instrument file.
190 schoenebeck 3253 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
191     - Built-in variable $EVENT_NOTE is now a read-only variable.
192     - Built-in variable $EVENT_VELOCITY is now a read-only variable.
193     - built-in "play_note()" function now accepts -2 for its fourth argument
194     (note duration) which means the life time of the note shall be sticked
195     to the requested note number of argument 1.
196     - Fix: built-in "play_note()" function now returns 0 as result value if
197     -1 was passed for its fourth argument (note duration) and the respective
198     parent note is already gone.
199 schoenebeck 3255 - Implemented built-in script function "change_play_pos()".
200 schoenebeck 3257 - NKSP language: Added support for user declared const array variables.
201     - NKSP language: Raise parser warning if array variable is accessed with
202     an index that exceeds the array's size.
203 schoenebeck 3259 - NKSP language fix: Unknown characters were not handled correctly.
204 schoenebeck 2871
205 schoenebeck 3050 * Instruments DB:
206     - Fixed memory access bug of general DB access code which lead to
207     undefined behavior.
208 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
209     - The instrument DB path of linuxsampler's --create-instruments-db argument
210     is now optional, if it is missing, then a default location is used.
211 schoenebeck 3092 - Added support for scanning SFZ (.sfz) files.
212     - Added support for scanning Sound Font (.sf2) files.
213 schoenebeck 3101 - Fixed undefined DB transaction behavior.

254 persson 2382
255 persson 2086 * general changes:
256 iliev 2012 - Refactoring: moved the independent code from
257     the Gigasampler format engine to base classes
258 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
259     respective profiling code is currently broken
260 schoenebeck 2053 - Introduced support for optional environment variable
261     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
262     where the sampler shall look for instrument editor plugins
263     (patch by Luis Garrido, slightly modified).
264 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
265     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
266     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
267     note (in this implementation of the sampler its simply hard routed to
268     the 1st effect send of the sampler channel, no matter what the actual
269     effect type is)
270     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
271     note (in this implementation of the sampler its simply hard routed to
272     the 2nd effect send of the sampler channel, no matter what the actual
273     effect type is)
274 schoenebeck 2124 - implemented support for internal LADSPA effects
275 schoenebeck 2140 - raised limit of program change queue from 100 to 512
276     (as suggested by Alex Stone)
277 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
278 iliev 2296 - experimental support for per voice equalization
279 iliev 2306 - added command line option --exec-after-init
280 schoenebeck 2330 - Introduced new C++ API method:
281     EngineChannel::InstrumentFileName(int index)
282     allowing to retrieve the whole list of files used for the loaded
283     instrument on an engine channel (a.k.a. part). Some GigaStudio
284     instruments for example are splitted over several files like
285     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
286 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
287     - Added new C++ API method Sampler::GetGlobalMaxStreams().
288     - Added new C++ API method Sampler::SetGlobalMaxVoices().
289     - Added new C++ API method Sampler::SetGlobalMaxStreams().
290 schoenebeck 2377 - Various "const" and "restrict" optimizations.
291 persson 2382 - all engines: add pan CC value to instrument pan parameter before
292     applying panning, instead of using two separate pan functions in
293     series (#182)
294 persson 2427 - added a lock guard class for exception safe mutex handling and
295     used it everywhere appropriate
296 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
297     - Exposed scale tuning to C++ API (along to the already existing standard
298     SysEx way).
299 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
300     and broken for ppc64. (Seq_cst loads and stores are actually not
301     used in LS, so the bug wasn't noticable.)
302     - lsatomic.h: added ARMv7 support
303 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
304     added various new C++ methods for this new feature / design change, old
305     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
306     as deprecated but are still there and should provide full behavior
307     backward compatibility).
308     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
309     unsafe and caused compilation error with clang 2.x).
310 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
311 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
312     sampler from the command line by providing LSCP aware features.
313 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
314     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
315     - VirtualMidiDevice: Added support for pitch bend.
316 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
317     polyphonic key pressure events (so far polyphonic pressure was not
318     supported at all, and channel pressure was rerouted as CC128 but not
319     used so far).
320 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
321     code is shared by all sampler engine implemementations, however only the
322     gig file format currently provides support for storing instrument scripts
323     (as LinuxSampler extension to the original GigaStudio 4 format).
324 iliev 2012
325 persson 2043 * Gigasampler format engine:
326     - implemented the "round robin keyboard" dimension
327     - fixed round robin and random dimensions for cases when number of
328     dimension zones is not a power of two
329     - made round robin use a counter for each region instead of each
330     key
331 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
332     - bugfix: filter keyboard tracking was broken
333     - filter performance fix (an unnecessary copy was made of the
334     filter parameters in each sub fragment)
335     - handle special case when pan parameter in gig file has max or
336     min value
337 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
338     doesn't sound naturally with a drumkit
339 persson 2408 - fixed EG1 modulation when attack or release is zero
340 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
341 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
342     conditions (see also previous commit on libgig).
343 persson 2673 - fixed behaviour of filter LFO
344 persson 2043
345 schoenebeck 2047 * SFZ format engine:
346 iliev 2012 - Initial implementation (not usable yet)
347 persson 2055 - added support for v2 multiple stage envelope generators
348     - added a fine-tuned v1 envelope generator instead of using the
349     one from the gig engine
350 persson 2058 - fixed memory leak and memory handling errors
351 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
352 persson 2058 - allow non-numerical key values ("C#4" for example)
353     - "key" opcode now sets pitch_keycenter too
354     - fixed error when unloading instrument with same sample used by
355     multiple regions
356     - added some opcode aliases, like loopmode for loop_mode, to be
357     more compatible
358 persson 2061 - added support for trigger=release and rt_decay
359 persson 2063 - added support for off_mode=normal
360 persson 2072 - added support for random, seq_position, seq_length and volume
361     - added v1 LFO opcodes to parser (no support in engine yet)
362 persson 2082 - added support for amp_veltrack and amp_velcurve_N
363     - fine-tuned the default velocity curve
364 persson 2086 - added support for transpose
365     - fixed crash when using sw_down/up
366     - improved logic for sw_lokey/hikey/up/down/last
367     - added more v1 aliases to parser
368 persson 2091 - reduced memory usage for sfz data
369 persson 2101 - RT-safeness: avoid malloc in audio thread
370     - fixed a bug that could cause voice stealing to fail
371 persson 2106 - optimized sample lookup
372 persson 2114 - improved support for exclusive groups (group, off_by and

707 iliev 2201 - fixed crash which occurred when changing an already deployed sampler
708 schoenebeck 2123 channel to a different engine type
709 persson 2127 - fixed crash when deleting a sampler channel or changing engine
710     type while an instrument load was in progress
711 persson 2162 - bugfix: playing a note while changing the instrument could cause
712     a crash, or give "Handing back unknown region" error messages
713 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
714     refresh) could cause instruments to be unloaded

716     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
717 persson 2185 - Mac OS X: fixed hanging threads

721     after MIDI/audio device creation failure
722 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
723     instruments were uselessly precached with zero samples, however it still
724     took the full preloading time and on 1st program change the respective
725     instrument was completely reloaded again.
726 persson 2277 - fixed handling of rapid bank select and program change messages
727     sent to the same sampler channel (patch from the Open Octave
728     project, slightly adjusted)

745     (labelled "Disk stream not available in time")
746 schoenebeck 2413 - Update effects on sample rate & period size changes (to avoid
747     crashes and noise on such transitions).
748 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
749     (fixes #208)
750 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
751     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
752     practically irrelevant, however it caused problems with the new LSCP
753     shell's auto completion feature).
754 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
755     after each other (fixes #231).

805 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
806     be switched on by command line option "--stacktrace" (the automatic
807     stacktrace mechanism seems to be broken on most systems at the moment)
808 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
809     a pointer to the launched InstrumentEditor object
810 schoenebeck 1876 - added optional 3rd party user data parameter for following
811     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

832 persson 1748 jack_client_new
833 iliev 1829 - added (experimental) CoreAudio driver
834 persson 1888 - applied old fixes to the ASIO driver that were included in the
835     previous binary release but accidentally never committed to CVS
836     (fixes #117)
837 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
838     win64)

847     stored in the plugin state
848 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
849     AudioChannel::CopyTo() methods using GCC vector exensions
850     (if available)
851 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
852     exception when getting parameters from a disconnected device
853 schoenebeck 1599
854 persson 1651 * MIDI driver:
855     - added JACK MIDI driver
856 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
857     want to (mis)use it for some purpose ("fixed" in all current MIDI
858     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
859 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
860 persson 1887 CoreMidi or AU
861 persson 1889 - fixed mingw-w64 compilation error in MME driver
862 persson 1924 - made program change handling in MIDI thread real-time safe by

873 persson 1908 - work-around for missing fnmatch function on Windows to make
874     instrument database compilable
875 schoenebeck 1930 - added instrument database support on Windows
876     works with both standalone mode and VST plugin.
877     the instruments DB file is located in
878     %USERPROFILE%\.linuxsampler\instruments.db which allows different
879     databases for each windows user
880     if no DB is present it automatically creates the .linuxsampler subdir
881     and then creates an empty DB
882 persson 1943 - fixed recursive import, which was broken on Windows
883 iliev 1603
884 persson 1644 * Gigasampler format engine:
885     - fixed a memory leak that could happen when a channel was deleted
886     while notes were playing
887 persson 1646 - made it possible to load an instrument even if the audio thread
888     isn't running
889 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
890     enough for piano gigs with pedal noise samples
891 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
892     respective FX send MIDI controller was used
893 schoenebeck 1724 - added support for GM global device volume SysEx message
894 schoenebeck 1762 (can be selected at compile time to either apply globally to the
895     whole sampler [default] or only to the sampler channels that are
896     connected to the respective MIDI input port the SysEx message arrived
897     on)
898 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
899     sometimes wrongly killed in the same buffer, causing no sound to
900     be played
901 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
902     which is usally used to switch a part between chromatic sounds and
903     drumkit sounds (as opposed to their common default setting of MIDI
904     part 10 being a drumkit part and all other ones chromatic parts), in
905     LS however one can switch between the first 16 MIDI instrument maps
906     defined for the sampler
907 persson 1764 - made it possible to create multiple sample channels even if the
908     audio thread isn't running
909 persson 1844 - fixed crash when removing channel with active voices (#116)
910 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
911     un-cache the respective sample if it's really not used by any
912     sampler engine anymore
913     - re-cache samples in case they were changed by an instrument editor,
914     e.g. when a sample was added while playing (#82)
915 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
916     same time stamp as the voice's note-on event and occured both in the
917     same audio fragment cycle (fixes bug #112)
918 persson 1858 - added support for the "fine tune" and "pitch bend range"
919     instrument-level gig parameters
920     - fixed minor artifacts in pitch bend handling
921 schoenebeck 1860 - added support for GS Reset SysEx message
922 persson 1862 - allow gig files to use unlimited downward pitch shifting
923     - added a limit check for upward pitch shifting
924 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
925     note was silent
926 persson 1923 - fixed crash happening when a pitch bend event arrived at the
927     same time a new instrument was loading
928 persson 1644
929 schoenebeck 1687 * LSCP server:
930     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
931     react on MIDI data arriving on certain sampler channels (so far only
932     Note-On and Note-Off events are sent via this LSCP event)
933 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
934     react on MIDI data arriving on certain MIDI input devices (so far only
935     Note-On and Note-Off events are sent via this LSCP event)
936 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
937     SET DB_INSTRUMENT FILE_PATH
938 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
939     frontends to send MIDI messages to specific sampler channel
940     - added two additional fields to GET FILE INSTRUMENT INFO command -
941     KEY_BINDINGS and KEYSWITCH_BINDINGS
942 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
943     was incorrect
944 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
945 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
946     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
947     be triggered respectively
948     - added new LSCP command "SET STREAMS" to globally alter the maximum
949     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
950     which will be triggered respectively
951 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
952     a gigedit file dialog is opened)
953 iliev 1848 - close all connections when LSCPServer is deleted
954 iliev 1882 - hard close of all sockets on exit
955 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
956     driver
957 schoenebeck 1687
958 iliev 1761 * Bug fixes:
959     - fixed a crash which occurs when removing a sampler channel waiting
960     to start instrument loading after another channel
961 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
962     instrument loading in progress (bug #113)
963 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
964     instrument with PERSISTENT load mode
965 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
966     - fixed memory leaks when issuing the following LSCP commands:
967     GET AUDIO_OUTPUT_DRIVER INFO
968     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
969     GET MIDI_INPUT_DRIVER INFO
970     GET MIDI_INPUT_DRIVER_PARAMETER INFO
971     - fixed possible compilation error when sqlite is not present
972 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
973 iliev 1847 - fixed crash when changing the audio output device of a sampler
974     channel with loaded instrument and start playing notes
975 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
976 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
977     PowerPC, which probably could cause crashes on that platform
978 persson 1889 - fixed a memory management error which could cause a crash when a
979     plugin was unloaded
980 persson 1896 - bugfix: two private structs had the same name, which could cause
981     problems if the linker chose the wrong constructor
982 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
983     Windows
984 iliev 1761
985    
986 schoenebeck 1560 Version 0.5.1 (6 December 2007)
987 schoenebeck 1454
988     * packaging changes:
989     - added autoconf checks for pthread library
990     - added autoconf check for pthread bug found on certain NPTL-enabled
991     glibc versions (see Gentoo bug report #194076)
992 senoner 1502 - added autoconf checks for MS Windows
993 schoenebeck 1454
994 persson 1455 * general changes:
995     - bugfix: the thread used by an editor plugin didn't die when the
996     editor closed
997 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
998     out all the space. operator--() did not apply size_mask after
999     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1000     order to avoid problems with the _NonVolatileReader functions.
1001     - bugfix: Stream.h: added a missing divide by BytesPerSample in
1002     GetWriteSpace(). Since this function is currently only used in
1003     the stream's qsort() compare function, it didn't trigger any
1004     bugs.
1005     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1006     24bit mode too. Faster method to read 24bit words on little
1007     endian machines (x86): replaced 3 byte reads + shifts with a 1
1008     unaligned 32bit read and shift
1009     - experimental support for MS Windows (MIDI input via MME, AUDIO
1010     output via ASIO)
1011     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1012 iliev 1541 - support for monitoring the total number of active disk streams
1013     (new LSCP commands: GET TOTAL_STREAM_COUNT,
1014     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1015 persson 1455
1016 senoner 1500 * AUDIO driver:
1017 persson 1534 - added Windows ASIO low latency audio driver
1018 senoner 1500
1019 senoner 1485 * MIDI driver:
1020 schoenebeck 1495 - added MME Windows MIDI driver
1021 senoner 1485
1022 schoenebeck 1471 * LSCP server:
1023     - added support for Windows style path / filenames, however with
1024     forward slash path separators instead of backslash
1025     (i.e. "C:/foo/bar.gig")
1026 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1027     apostrophes as well
1028 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1029     "LIST FILE INSTRUMENTS <file>" and
1030     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1031     about an arbitrary instrument file on the system where the sampler is
1032     running on
1033 schoenebeck 1471
1034 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1035 schoenebeck 947
1036 schoenebeck 1065 * packaging changes:
1037 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1038     API header files anymore
1039 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1040     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1041 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1042     capable to execute our autoconf environment, thus no need anymore
1043     to maintain the compile time configuration file (osx/version.h) for
1044     OSX manually (patch by Toshi Nagata)
1045 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1046     parameters
1047 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1048     C++ API header files, all implementation internal global definitions
1049     are now in global_private.h
1050     - atomic.h is not exposed to the C++ API anymore
1051     - no need to include config.h anymore for using LS's API header files
1052     - fixed warnings in API doc generation
1053 schoenebeck 1065
1054 schoenebeck 947 * general changes:
1055     - replaced the old, confusing MIDI program change mechanism by a
1056     flexible MIDI instrument mapper which allows to map arbitrary
1057 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1058 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1059     loaded on the respective channel when such MIDI program change
1060     messages arrive, beside that, each entry allows to define a life-time
1061     strategy for the instrument, so the user can define whether the
1062     instrument should i.e. be permanently loaded (to be able to switch
1063     quickly among sounds) or i.e. loaded just on demand when the
1064     respective program change arrives (to safe RAM space), as well as a
1065     global volume factor for each entry, so the user can adjust the volume
1066     dynamic of his mapped instrument collection without having to modify
1067 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1068     MIDI instrument maps and assign each sampler channel individually
1069     a certain map, so that i.e. separation of normal instruments and
1070     drumkits is possible
1071 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1072     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1073 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1074     due to a constant size RingBuffer FIFO which is now replaced by a
1075     dynamic (unlimited) size std::list FIFO
1076 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1077     output channels for being processed by external effect processors
1078     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1079     controllers
1080 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1081 iliev 1130 - Implemented new, improved notification system
1082 schoenebeck 1149 - fixed compilation errors regarding OSX
1083     (patch by Toshi Nagata)
1084 iliev 1161 - implemented instruments database
1085 iliev 1345 - added support for escape sequences to the instruments database
1086 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1087     within the sampler's process (by using instrument editor plugins),
1088     you'll notice the new "Registered instrument editors:" message on
1089 schoenebeck 1407 startup, added a new LSCP command:
1090     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1091 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1092     given sampler channel, the plugin path can be overridden at compile
1093     time with ./configure --enable-plugin-dir=/some/dir
1094 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1095     in the sampler's process to safely edit instruments while playing
1096     without a crash (hopefully) by either suspending single regions
1097     wherever possible or if unavoidable whole engine(s)
1098 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1099     policy and priority on thread level, set a minimum stack size for
1100     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1101     threads simply inherited properties of starting thread instead of
1102     setting their own policy and priority
1103 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1104     main process did not wait for the stack trace process to finish
1105     its output
1106 persson 1248 - fixed some minor memory leaks
1107 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1108     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1109 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1110     register, to avoid relocations in the text segment at runtime)
1111 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1112 schoenebeck 947
1113     * MIDI driver:
1114     - dispatch bank select (MSB and LSB) messages
1115    
1116 schoenebeck 1049 * audio driver:
1117     - the ALSA audio output driver parameters now reflect the correct
1118     parameter value ranges for the respective selected sound card
1119     (patch by Till Wimmer, a bit fixed and extended)
1120    
1121 persson 951 * Gigasampler format engine:
1122     - if a filter is used and EG2 finishes before EG1, let the voice
1123     die when EG2 has finished (this fixes a problem with clicks and
1124     voice starvation for some gigs)
1125 persson 1038 - playback is no longer disabled during instrument loading
1126     - all notes playing on a channel that changes its instrument keep
1127     playing with the old instrument until they get a note off
1128     command
1129 persson 1039 - EG fix: a release value of zero could cause noises or crash
1130 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1131 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1132     above max sustain level, which means that there is a decay phase
1133     even if sustain is 100%
1134 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1135     noises or crashes
1136 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1137 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1138     supplied to the configure script (fixes #46)
1139 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1140     instead of a fix value
1141 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1142     127 (solo mode) only kill voices if the respective mode really
1143     changed
1144 persson 951
1145 schoenebeck 1244 * LSCP server:
1146     - fixed compile time error for old Bison versions
1147     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1148 schoenebeck 1245 - parser now supports extended ASCII character set
1149     (up to ASCII code 255, i.e. includes now umlauts and accents)
1150     - filename arguments in LSCP commands now allow to use escape
1151     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1152     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1153     code value like \xf2) (fixes bug #24)
1154 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1155     least one of their text-based parameters (i.e. name, description):
1156     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1157     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1158     "SET DB_INSTRUMENT_DIRECTORY NAME",
1159     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1160     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1161     "FIND DB_INSTRUMENT_DIRECTORIES"
1162 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1163     occured, the unexpected character and the actually expected, possible
1164     character(s), the latter only if less than 5 possibilities)
1165 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1166     settings
1167 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1168     of strings were treated as being one string containing commas
1169     (fixes #57)
1170 schoenebeck 1244
1171 iliev 959 * Bug fixes:
1172     - fixed crash occurring on certain LSCP scripts (Bug 39)
1173 persson 1038 - another thread safety fix for lscp "load engine" and "set
1174     channel audio output device"
1175 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1176     on a sampler channel with connected MIDI device
1177 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1178     device connected to a sampler channel to number less then or equal
1179     to the index of the port to which the sampler channel is connected.
1180 iliev 1296 - The previous bindings were not been disconnected when altering
1181     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1182     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1183 iliev 1297 - The active stream/voice count statistic was incorrect.
1184 iliev 1298 - notification events were not been sent for some sampler
1185     channel changes
1186 iliev 1305 - added default min and max values to restrict the number of allowed
1187     audio output channels and MIDI input ports
1188 iliev 1306 - the connection to the PCM interface is now closed when destroying
1189     an audio output device
1190 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1191 iliev 959
1192 schoenebeck 1221 * test cases:
1193     - updated and fixed (haven't been touched in a while)
1194    
1195 schoenebeck 937 Version 0.4.0 (24 November 2006)
1196 persson 696
1197 schoenebeck 697 * packaging changes:
1198 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1199     to post-(un)install steps; added devel package for liblinuxsampler;
1200     to linuxsampler.spec (RPM)
1201 schoenebeck 697 - install necessary development header files for allowing 3rd party
1202     applications to link against liblinuxsampler
1203     - liblinuxsampler's API documentation can be generated with 'make docs'
1204     (Doxygen required)
1205 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1206     implementation (currently either an integer math solution or a
1207     di-harmonic approximation), automatic detection can be overriden
1208     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1209     configure script argument though (mandatory for cross-compilation)
1210 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1211     provided some on his own (as CXXFLAGS)
1212 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1213     messages
1214 schoenebeck 852 - added compile time options to allow disabling the various audio and
1215     MIDI drivers
1216 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1217     (patch by Ebrahim Mayat)
1218 schoenebeck 697
1219 persson 696 * Gigasampler format engine:
1220 schoenebeck 738 - extensive synthesis optimization
1221     (reimplementation of EGs and LFO(s), removed synthesis parameter
1222     prerendering and the synthesis parameter matrix in general, splitting
1223     each audio fragment into subfragments now where each subfragment uses
1224 persson 830 constant pitch and filter coefficients. The volume coefficient is
1225     linearly interpolated inside a subfragment, unless
1226     --disable-interpolate-volume is set.)
1227 persson 696 - fine tuning of the EG modulation parameters
1228 persson 729 - improved filter cutoff calculation by adding support for the
1229     following gig parameters: Cutoff freq (used when no cutoff
1230     controller is defined), Control invert, Minimum cutoff, Velocity
1231 persson 791 curve and Velocity range. The keyboard tracking now scales
1232     cutoff frequency instead of resonance.
1233 persson 877 - added support for gig parameter Resonance.
1234 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1235 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1236     which can be overridden with --enable-global-attenuation
1237 persson 783 - EG fixes: made the length of "attack hold" stage more
1238     accurate. Release stage can now start before attack stage
1239 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1240     time now has a minimal value to prevent clicks.
1241 persson 799 - fixed pitch changes larger than one octave
1242 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1243     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1244     all modes can be altered via standard GM messages, that is CC5 for
1245     altering portamento time, CC65 for enabling / disabling portamento
1246     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1247 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1248     parameter) and crossfade
1249 persson 831 - added support for the "attenuation controller threshold" gig
1250     parameter
1251 persson 832 - added smoothing of volume changes caused by control change
1252     messages
1253 persson 865 - sample loop parameters are now taken from the DimensionRegion
1254     instead of the wave chunk
1255     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1256     not equal to a power of two
1257 persson 877 - reimplementation of the filter algorithm. The new filter is more
1258     accurate and supports all gig filter types, including bandreject
1259     and lowpass turbo.
1260 persson 903 - real support for 24 bit samples - samples are not truncated to
1261     16 bits anymore
1262     - support for aftertouch (channel pressure, not polyphonic
1263     aftertouch)
1264 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1265     amplifying from 0)
1266 persson 696
1267 schoenebeck 711 * LSCP server:
1268     - fixed application exit on broken pipe error (fixes bug #20)
1269 iliev 793 - fixed the notification messages delay due to lack of
1270     network activity (fixes bug #26)
1271 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1272     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1273 schoenebeck 711
1274 schoenebeck 838 * audio driver:
1275     - added aRts audio output driver (by no means RT safe)
1276    
1277 schoenebeck 775 * MIDI driver:
1278     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1279     messages several times instead of once
1280 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1281     for events (i.e. for offline rendering based MIDI drivers)
1282 persson 922 - added checks for bad MIDI data
1283 schoenebeck 775
1284 schoenebeck 900 * linuxsampler application:
1285     - show available sampler engine types on startup
1286    
1287 schoenebeck 705 * general changes:
1288     - support for muting sampler channels and solo mode of the same, two new
1289     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1290     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1291     introduced for this, the behavior is the same like on a mixer console
1292 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1293     --enable-process-muted-channels which can be used to enable the
1294     processing of muted channels.
1295 iliev 777 - support for sostenuto pedal
1296 iliev 779 - support for monitoring the total number of active voices
1297 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1298     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1299 persson 835 - fixed some memory management errors
1300 persson 841 - fixed some concurrency problems that could lead to crashes when
1301     LSCP commands were executed
1302 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1303     sampler channel (fixes bug #36)
1304 schoenebeck 705
1305 schoenebeck 692 Version 0.3.3 (15 July 2005)
1306 schoenebeck 686
1307     * packaging changes:
1308     - fixed compilation with gcc 4.0
1309    
1310 schoenebeck 687 * Gigasampler format engine:
1311     - LFO preprocessing was performed even though the respective LFO was
1312     disabled by the instrument patch (minor efficiency fix)
1313 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1314     for volume ramp downs in the same fragment (needed for current voice
1315     stealing implementation) then simply inform the user with a warning
1316     about possible click sounds and reduce the volume ramp down
1317     appropriately instead of cancelling the audio device connection
1318 schoenebeck 687
1319 schoenebeck 677 Version 0.3.2 (24 June 2005)
1320 schoenebeck 609
1321     * packaging changes:
1322     - updated autotools build files to compile on OS X
1323     (conditional compilation of CoreMIDI and MidiShare drivers)
1324 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1325     './configure --disable-asm' (definitely not recommended)
1326 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1327     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1328     (due to 'dist-bzip2' automake option)
1329 schoenebeck 649
1330     * Gigasampler format engine:
1331     - support for the gig parameters for "release velocity response" curves
1332     - fine tuning of the EGADSR envelope
1333     - volume of release triggered samples now depends on note-on velocity,
1334     note length and gig parameter "release trigger decay" instead of
1335     note-off velocity.
1336 schoenebeck 663 - revised voice stealing
1337     (fixes crash and endless loop caused by voice stealing)
1338 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1339 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1340     instead of when the respective voice is actually launched
1341     (fixes undefined behavior if stolen voices belonged to a key group -
1342     this case was followed by a "killed voice survived" error message)
1343 schoenebeck 669 - fixed minor issue with null/silence samples
1344     (those stole voices even though they don't need a voice at all which
1345     resulted in "voice stealing didn't work out" messages)
1346 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1347     instrument or audio output device change
1348 schoenebeck 654
1349 schoenebeck 620 * LSCP server:
1350 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1351 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1352 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1353 schoenebeck 609
1354 schoenebeck 668 * linuxsampler application:
1355     - added command line parameters --lscp-addr and --lscp-port to override
1356     default IP address and port of LSCP server
1357    
1358 schoenebeck 579 Version 0.3.1 (24 May 2005)
1359    
1360     * initial release
