* NKSP: built-in "play_note()" function now accepts -2 for its fourth
  argument (note duration) which means the life time of the note shall
  be sticked to the requested note number of argument 1.
* NKSP Fix: built-in "play_note()" function now returns 0 as result
  value if -1 was passed for its fourth argument (note duration) and
  the respective parent note is already gone.
* NKSP: Built-in array variable %KEY_DOWN[] is now a read-only
  variable.
* Built-in variable $EVENT_NOTE is now a read-only variable.
* Built-in variable $EVENT_VELOCITY is now a read-only variable.
* Bumped version (2.0.0.svn56).

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".
82 schoenebeck 2931 - Implemented built-in script function "change_vol()".
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 "$NKSP_IGNORE_WAIT".
114     - Added support for read-only built-in variables (respectively
115     handled by the script parser).
116     - Added built-in script constant "$NI_CB_TYPE_INIT".
117     - Added built-in script constant "$NI_CB_TYPE_NOTE".
118     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

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.

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 2871
200 schoenebeck 3050 * Instruments DB:
201     - Fixed memory access bug of general DB access code which lead to
202     undefined behavior.
203 schoenebeck 3091 - Cleanup of instruments DB file creation and opening code.
204     - The instrument DB path of linuxsampler's --create-instruments-db argument
205     is now optional, if it is missing, then a default location is used.

221 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
222 persson 2197 - minor Makefile fix for building lscpparser when build and source
223     directories are separate
224 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to

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

355 persson 2072 - added support for random, seq_position, seq_length and volume
356     - added v1 LFO opcodes to parser (no support in engine yet)
357 persson 2082 - added support for amp_veltrack and amp_velcurve_N
358     - fine-tuned the default velocity curve
359 persson 2086 - added support for transpose
360     - fixed crash when using sw_down/up
361     - improved logic for sw_lokey/hikey/up/down/last
362     - added more v1 aliases to parser
363 persson 2091 - reduced memory usage for sfz data
364 persson 2101 - RT-safeness: avoid malloc in audio thread
365     - fixed a bug that could cause voice stealing to fail
366 persson 2106 - optimized sample lookup

691     - Added built-in script int const variables $MARK_1 to $MARK_28.
692     - Built-in script functions "ignore_event()", "note_off()" and
693     "gig_set_dim_zone()" now also accept an array of event IDs as argument
694     (i.e. return value of new script function "by_marks()").
695 schoenebeck 2645 - Pass/preserve polyphonic variable data from respective "note" event
696     handler to "release" event handler.

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

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

715 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
716     after MIDI/audio device creation failure
717 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
718     instruments were uselessly precached with zero samples, however it still
719     took the full preloading time and on 1st program change the respective
720     instrument was completely reloaded again.
721 persson 2277 - fixed handling of rapid bank select and program change messages
722     sent to the same sampler channel (patch from the Open Octave
723     project, slightly adjusted)

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

787 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
788 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

823     reflected the wrong value
824 persson 1644 - fixed a memory management bug in ASIO driver
825 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

827 persson 1748 jack_client_new
828 iliev 1829 - added (experimental) CoreAudio driver
829 persson 1888 - applied old fixes to the ASIO driver that were included in the
830     previous binary release but accidentally never committed to CVS
831     (fixes #117)
832 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
833     win64)
834 persson 1895 - VST: added support for sample rate and buffer size changes

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

868 persson 1908 - work-around for missing fnmatch function on Windows to make
869     instrument database compilable
870 schoenebeck 1930 - added instrument database support on Windows
871     works with both standalone mode and VST plugin.
872     the instruments DB file is located in
873     %USERPROFILE%\.linuxsampler\instruments.db which allows different
874     databases for each windows user
875     if no DB is present it automatically creates the .linuxsampler subdir
876     and then creates an empty DB
877 persson 1943 - fixed recursive import, which was broken on Windows
878 iliev 1603
879 persson 1644 * Gigasampler format engine:
880     - fixed a memory leak that could happen when a channel was deleted
881     while notes were playing
882 persson 1646 - made it possible to load an instrument even if the audio thread
883     isn't running
884 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
885     enough for piano gigs with pedal noise samples
886 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
887     respective FX send MIDI controller was used
888 schoenebeck 1724 - added support for GM global device volume SysEx message
889 schoenebeck 1762 (can be selected at compile time to either apply globally to the
890     whole sampler [default] or only to the sampler channels that are
891     connected to the respective MIDI input port the SysEx message arrived
892     on)
893 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
894     sometimes wrongly killed in the same buffer, causing no sound to
895     be played
896 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
897     which is usally used to switch a part between chromatic sounds and
898     drumkit sounds (as opposed to their common default setting of MIDI
899     part 10 being a drumkit part and all other ones chromatic parts), in
900     LS however one can switch between the first 16 MIDI instrument maps
901     defined for the sampler
902 persson 1764 - made it possible to create multiple sample channels even if the
903     audio thread isn't running
904 persson 1844 - fixed crash when removing channel with active voices (#116)
905 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
906     un-cache the respective sample if it's really not used by any
907     sampler engine anymore
908     - re-cache samples in case they were changed by an instrument editor,
909     e.g. when a sample was added while playing (#82)
910 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
911     same time stamp as the voice's note-on event and occured both in the
912     same audio fragment cycle (fixes bug #112)
913 persson 1858 - added support for the "fine tune" and "pitch bend range"
914     instrument-level gig parameters
915     - fixed minor artifacts in pitch bend handling
916 schoenebeck 1860 - added support for GS Reset SysEx message
917 persson 1862 - allow gig files to use unlimited downward pitch shifting
918     - added a limit check for upward pitch shifting
919 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
920     note was silent
921 persson 1923 - fixed crash happening when a pitch bend event arrived at the
922     same time a new instrument was loading
923 persson 1644
924 schoenebeck 1687 * LSCP server:
925     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
926     react on MIDI data arriving on certain sampler channels (so far only
927     Note-On and Note-Off events are sent via this LSCP event)
928 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
929     react on MIDI data arriving on certain MIDI input devices (so far only
930     Note-On and Note-Off events are sent via this LSCP event)
931 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
932     SET DB_INSTRUMENT FILE_PATH
933 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
934     frontends to send MIDI messages to specific sampler channel
935     - added two additional fields to GET FILE INSTRUMENT INFO command -
936     KEY_BINDINGS and KEYSWITCH_BINDINGS
937 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
938     was incorrect
939 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
940 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
941     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
942     be triggered respectively
943     - added new LSCP command "SET STREAMS" to globally alter the maximum
944     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
945     which will be triggered respectively
946 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
947     a gigedit file dialog is opened)
948 iliev 1848 - close all connections when LSCPServer is deleted
949 iliev 1882 - hard close of all sockets on exit
950 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
951     driver
952 schoenebeck 1687
953 iliev 1761 * Bug fixes:
954     - fixed a crash which occurs when removing a sampler channel waiting
955     to start instrument loading after another channel
956 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
957     instrument loading in progress (bug #113)
958 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
959     instrument with PERSISTENT load mode
960 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
961     - fixed memory leaks when issuing the following LSCP commands:
962     GET AUDIO_OUTPUT_DRIVER INFO
963     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
964     GET MIDI_INPUT_DRIVER INFO
965     GET MIDI_INPUT_DRIVER_PARAMETER INFO
966     - fixed possible compilation error when sqlite is not present
967 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
968 iliev 1847 - fixed crash when changing the audio output device of a sampler
969     channel with loaded instrument and start playing notes
970 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
971 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
972     PowerPC, which probably could cause crashes on that platform
973 persson 1889 - fixed a memory management error which could cause a crash when a
974     plugin was unloaded
975 persson 1896 - bugfix: two private structs had the same name, which could cause
976     problems if the linker chose the wrong constructor
977 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
978     Windows
979 iliev 1761

981 schoenebeck 1560 Version 0.5.1 (6 December 2007)
982 schoenebeck 1454
983     * packaging changes:
984     - added autoconf checks for pthread library
985     - added autoconf check for pthread bug found on certain NPTL-enabled
986     glibc versions (see Gentoo bug report #194076)
987 senoner 1502 - added autoconf checks for MS Windows
988 schoenebeck 1454
989 persson 1455 * general changes:
990     - bugfix: the thread used by an editor plugin didn't die when the
991     editor closed
992 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
993     out all the space. operator--() did not apply size_mask after
994     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
995     order to avoid problems with the _NonVolatileReader functions.
996     - bugfix: Stream.h: added a missing divide by BytesPerSample in
997     GetWriteSpace(). Since this function is currently only used in
998     the stream's qsort() compare function, it didn't trigger any
999     bugs.
1000     - Resampler.h, Synthesizer.h: cubic interpolation now works in
1001     24bit mode too. Faster method to read 24bit words on little
1002     endian machines (x86): replaced 3 byte reads + shifts with a 1
1003     unaligned 32bit read and shift
1004     - experimental support for MS Windows (MIDI input via MME, AUDIO
1005     output via ASIO)
1006     - made handling of SIGINT signal (Ctrl-C) a bit more robust
1007 iliev 1541 - support for monitoring the total number of active disk streams

1009     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1010 persson 1455
1011 senoner 1500 * AUDIO driver:
1012 persson 1534 - added Windows ASIO low latency audio driver
1013 senoner 1500
1014 senoner 1485 * MIDI driver:
1015 schoenebeck 1495 - added MME Windows MIDI driver
1016 senoner 1485
1017 schoenebeck 1471 * LSCP server:
1018     - added support for Windows style path / filenames, however with
1019     forward slash path separators instead of backslash
1020     (i.e. "C:/foo/bar.gig")
1021 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
1022     apostrophes as well
1023 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1024     "LIST FILE INSTRUMENTS <file>" and
1025     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1026     about an arbitrary instrument file on the system where the sampler is
1027     running on
1028 schoenebeck 1471
1029 schoenebeck 1424 Version 0.5.0 (15 October 2007)
1030 schoenebeck 947
1031 schoenebeck 1065 * packaging changes:
1032 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
1033     API header files anymore
1034 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
1035     the Doxygen API documentation (explicitly listed in Doxyfile.in)
1036 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
1037     capable to execute our autoconf environment, thus no need anymore
1038     to maintain the compile time configuration file (osx/version.h) for
1039     OSX manually (patch by Toshi Nagata)
1040 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
1041     parameters
1042 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
1043     C++ API header files, all implementation internal global definitions
1044     are now in global_private.h
1045     - atomic.h is not exposed to the C++ API anymore
1046     - no need to include config.h anymore for using LS's API header files
1047     - fixed warnings in API doc generation
1048 schoenebeck 1065
1049 schoenebeck 947 * general changes:
1050     - replaced the old, confusing MIDI program change mechanism by a
1051     flexible MIDI instrument mapper which allows to map arbitrary
1052 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
1053 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
1054     loaded on the respective channel when such MIDI program change
1055     messages arrive, beside that, each entry allows to define a life-time
1056     strategy for the instrument, so the user can define whether the
1057     instrument should i.e. be permanently loaded (to be able to switch
1058     quickly among sounds) or i.e. loaded just on demand when the
1059     respective program change arrives (to safe RAM space), as well as a
1060     global volume factor for each entry, so the user can adjust the volume
1061     dynamic of his mapped instrument collection without having to modify
1062 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
1063     MIDI instrument maps and assign each sampler channel individually
1064     a certain map, so that i.e. separation of normal instruments and
1065     drumkits is possible
1066 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1067     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1068 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1069     due to a constant size RingBuffer FIFO which is now replaced by a
1070     dynamic (unlimited) size std::list FIFO
1071 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1072     output channels for being processed by external effect processors
1073     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1074     controllers
1075 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1076 iliev 1130 - Implemented new, improved notification system
1077 schoenebeck 1149 - fixed compilation errors regarding OSX
1078     (patch by Toshi Nagata)
1079 iliev 1161 - implemented instruments database
1080 iliev 1345 - added support for escape sequences to the instruments database
1081 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1082     within the sampler's process (by using instrument editor plugins),
1083     you'll notice the new "Registered instrument editors:" message on
1084 schoenebeck 1407 startup, added a new LSCP command:
1085     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1086 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1087     given sampler channel, the plugin path can be overridden at compile
1088     time with ./configure --enable-plugin-dir=/some/dir
1089 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1090     in the sampler's process to safely edit instruments while playing
1091     without a crash (hopefully) by either suspending single regions
1092     wherever possible or if unavoidable whole engine(s)
1093 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1094     policy and priority on thread level, set a minimum stack size for
1095     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1096     threads simply inherited properties of starting thread instead of
1097     setting their own policy and priority
1098 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1099     main process did not wait for the stack trace process to finish
1100     its output
1101 persson 1248 - fixed some minor memory leaks
1102 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1103     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1104 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1105     register, to avoid relocations in the text segment at runtime)
1106 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1107 schoenebeck 947
1108     * MIDI driver:
1109     - dispatch bank select (MSB and LSB) messages
1110    
1111 schoenebeck 1049 * audio driver:
1112     - the ALSA audio output driver parameters now reflect the correct
1113     parameter value ranges for the respective selected sound card
1114     (patch by Till Wimmer, a bit fixed and extended)
1115    
1116 persson 951 * Gigasampler format engine:
1117     - if a filter is used and EG2 finishes before EG1, let the voice
1118     die when EG2 has finished (this fixes a problem with clicks and
1119     voice starvation for some gigs)
1120 persson 1038 - playback is no longer disabled during instrument loading
1121     - all notes playing on a channel that changes its instrument keep
1122     playing with the old instrument until they get a note off
1123     command
1124 persson 1039 - EG fix: a release value of zero could cause noises or crash
1125 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1126 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1127     above max sustain level, which means that there is a decay phase
1128     even if sustain is 100%
1129 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1130     noises or crashes
1131 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1132 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1133     supplied to the configure script (fixes #46)
1134 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1135     instead of a fix value
1136 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1137     127 (solo mode) only kill voices if the respective mode really
1138     changed
1139 persson 951
1140 schoenebeck 1244 * LSCP server:
1141     - fixed compile time error for old Bison versions
1142     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1143 schoenebeck 1245 - parser now supports extended ASCII character set
1144     (up to ASCII code 255, i.e. includes now umlauts and accents)
1145     - filename arguments in LSCP commands now allow to use escape
1146     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1147     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1148     code value like \xf2) (fixes bug #24)
1149 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1150     least one of their text-based parameters (i.e. name, description):
1151     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1152     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1153     "SET DB_INSTRUMENT_DIRECTORY NAME",
1154     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1155     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1156     "FIND DB_INSTRUMENT_DIRECTORIES"
1157 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1158     occured, the unexpected character and the actually expected, possible
1159     character(s), the latter only if less than 5 possibilities)
1160 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1161     settings
1162 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1163     of strings were treated as being one string containing commas
1164     (fixes #57)
1165 schoenebeck 1244
1166 iliev 959 * Bug fixes:
1167     - fixed crash occurring on certain LSCP scripts (Bug 39)
1168 persson 1038 - another thread safety fix for lscp "load engine" and "set
1169     channel audio output device"
1170 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1171     on a sampler channel with connected MIDI device
1172 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1173     device connected to a sampler channel to number less then or equal
1174     to the index of the port to which the sampler channel is connected.
1175 iliev 1296 - The previous bindings were not been disconnected when altering
1176     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1177     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1178 iliev 1297 - The active stream/voice count statistic was incorrect.
1179 iliev 1298 - notification events were not been sent for some sampler
1180     channel changes
1181 iliev 1305 - added default min and max values to restrict the number of allowed
1182     audio output channels and MIDI input ports
1183 iliev 1306 - the connection to the PCM interface is now closed when destroying
1184     an audio output device
1185 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1186 iliev 959
1187 schoenebeck 1221 * test cases:
1188     - updated and fixed (haven't been touched in a while)
1189    
1190 schoenebeck 937 Version 0.4.0 (24 November 2006)
1191 persson 696
1192 schoenebeck 697 * packaging changes:
1193 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1194     to post-(un)install steps; added devel package for liblinuxsampler;
1195     to linuxsampler.spec (RPM)
1196 schoenebeck 697 - install necessary development header files for allowing 3rd party
1197     applications to link against liblinuxsampler
1198     - liblinuxsampler's API documentation can be generated with 'make docs'
1199     (Doxygen required)
1200 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1201     implementation (currently either an integer math solution or a
1202     di-harmonic approximation), automatic detection can be overriden
1203     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1204     configure script argument though (mandatory for cross-compilation)
1205 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1206     provided some on his own (as CXXFLAGS)
1207 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1208     messages
1209 schoenebeck 852 - added compile time options to allow disabling the various audio and
1210     MIDI drivers
1211 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1212     (patch by Ebrahim Mayat)
1213 schoenebeck 697
1214 persson 696 * Gigasampler format engine:
1215 schoenebeck 738 - extensive synthesis optimization
1216     (reimplementation of EGs and LFO(s), removed synthesis parameter
1217     prerendering and the synthesis parameter matrix in general, splitting
1218     each audio fragment into subfragments now where each subfragment uses
1219 persson 830 constant pitch and filter coefficients. The volume coefficient is
1220     linearly interpolated inside a subfragment, unless
1221     --disable-interpolate-volume is set.)
1222 persson 696 - fine tuning of the EG modulation parameters
1223 persson 729 - improved filter cutoff calculation by adding support for the
1224     following gig parameters: Cutoff freq (used when no cutoff
1225     controller is defined), Control invert, Minimum cutoff, Velocity
1226 persson 791 curve and Velocity range. The keyboard tracking now scales
1227     cutoff frequency instead of resonance.
1228 persson 877 - added support for gig parameter Resonance.
1229 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1230 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1231     which can be overridden with --enable-global-attenuation
1232 persson 783 - EG fixes: made the length of "attack hold" stage more
1233     accurate. Release stage can now start before attack stage
1234 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1235     time now has a minimal value to prevent clicks.
1236 persson 799 - fixed pitch changes larger than one octave
1237 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1238     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1239     all modes can be altered via standard GM messages, that is CC5 for
1240     altering portamento time, CC65 for enabling / disabling portamento
1241     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1242 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1243     parameter) and crossfade
1244 persson 831 - added support for the "attenuation controller threshold" gig
1245     parameter
1246 persson 832 - added smoothing of volume changes caused by control change
1247     messages
1248 persson 865 - sample loop parameters are now taken from the DimensionRegion
1249     instead of the wave chunk
1250     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1251     not equal to a power of two
1252 persson 877 - reimplementation of the filter algorithm. The new filter is more
1253     accurate and supports all gig filter types, including bandreject
1254     and lowpass turbo.
1255 persson 903 - real support for 24 bit samples - samples are not truncated to
1256     16 bits anymore
1257     - support for aftertouch (channel pressure, not polyphonic
1258     aftertouch)
1259 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1260     amplifying from 0)
1261 persson 696
1262 schoenebeck 711 * LSCP server:
1263     - fixed application exit on broken pipe error (fixes bug #20)
1264 iliev 793 - fixed the notification messages delay due to lack of
1265     network activity (fixes bug #26)
1266 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1267     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1268 schoenebeck 711
1269 schoenebeck 838 * audio driver:
1270     - added aRts audio output driver (by no means RT safe)
1271    
1272 schoenebeck 775 * MIDI driver:
1273     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1274     messages several times instead of once
1275 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1276     for events (i.e. for offline rendering based MIDI drivers)
1277 persson 922 - added checks for bad MIDI data
1278 schoenebeck 775
1279 schoenebeck 900 * linuxsampler application:
1280     - show available sampler engine types on startup
1281    
1282 schoenebeck 705 * general changes:
1283     - support for muting sampler channels and solo mode of the same, two new
1284     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1285     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1286     introduced for this, the behavior is the same like on a mixer console
1287 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1288     --enable-process-muted-channels which can be used to enable the
1289     processing of muted channels.
1290 iliev 777 - support for sostenuto pedal
1291 iliev 779 - support for monitoring the total number of active voices
1292 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1293     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1294 persson 835 - fixed some memory management errors
1295 persson 841 - fixed some concurrency problems that could lead to crashes when
1296     LSCP commands were executed
1297 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1298     sampler channel (fixes bug #36)
1299 schoenebeck 705
1300 schoenebeck 692 Version 0.3.3 (15 July 2005)
1301 schoenebeck 686
1302     * packaging changes:
1303     - fixed compilation with gcc 4.0
1304    
1305 schoenebeck 687 * Gigasampler format engine:
1306     - LFO preprocessing was performed even though the respective LFO was
1307     disabled by the instrument patch (minor efficiency fix)
1308 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1309     for volume ramp downs in the same fragment (needed for current voice
1310     stealing implementation) then simply inform the user with a warning
1311     about possible click sounds and reduce the volume ramp down
1312     appropriately instead of cancelling the audio device connection
1313 schoenebeck 687
1314 schoenebeck 677 Version 0.3.2 (24 June 2005)
1315 schoenebeck 609
1316     * packaging changes:
1317     - updated autotools build files to compile on OS X
1318     (conditional compilation of CoreMIDI and MidiShare drivers)
1319 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1320     './configure --disable-asm' (definitely not recommended)
1321 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1322     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1323     (due to 'dist-bzip2' automake option)
1324 schoenebeck 649
1325     * Gigasampler format engine:
1326     - support for the gig parameters for "release velocity response" curves
1327     - fine tuning of the EGADSR envelope
1328     - volume of release triggered samples now depends on note-on velocity,
1329     note length and gig parameter "release trigger decay" instead of
1330     note-off velocity.
1331 schoenebeck 663 - revised voice stealing
1332     (fixes crash and endless loop caused by voice stealing)
1333 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1334 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1335     instead of when the respective voice is actually launched
1336     (fixes undefined behavior if stolen voices belonged to a key group -
1337     this case was followed by a "killed voice survived" error message)
1338 schoenebeck 669 - fixed minor issue with null/silence samples
1339     (those stole voices even though they don't need a voice at all which
1340     resulted in "voice stealing didn't work out" messages)
1341 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1342     instrument or audio output device change
1343 schoenebeck 654
1344 schoenebeck 620 * LSCP server:
1345 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1346 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1347 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1348 schoenebeck 609
1349 schoenebeck 668 * linuxsampler application:
1350     - added command line parameters --lscp-addr and --lscp-port to override
1351     default IP address and port of LSCP server
1352    
1353 schoenebeck 579 Version 0.3.1 (24 May 2005)
1354    
1355     * initial release
