Mon Jun 5 18:40:18 2017 UTC (6 years, 9 months ago) by schoenebeck
File size: 73892 byte(s)
* NKSP: Implemented built-in script function "abort()" which allows
  to abort another script handler by passing its callback ID.
* Bumped version (2.0.0.svn61).

1 Version SVN trunk (?)
2
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
5 - Removed code duplication in SFZ file loading code.
6 - Added support for sfz extension opcode 'script' which may be used to
7 load real-time instrument script file (NKSP script language).
8 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 - Fixed unintended volume fade-in of voices under certain conditions.
10
11 * Gigasampler/GigaStudio format engine:
12 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13 cutoff settings.
14
15 * general changes:
16 - fixed printf type errors (mostly in debug messages)
17 - use unique_ptr instead of auto_ptr when building with C++11
18 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19 allowing to sort data efficiently in real-time safe manner.
20 - RTList class: added methods for moving/inserting elements to arbitrary
21 position within a list.
22 - RTList class: added method fromPtr() for creating an Iterator object from
23 a raw element pointer.
24 - Attempt to partly fix resetting engine channels vs. resetting engine, an
25 overall cleanup of the Reset*(), ConnectAudioDevice(),
26 DisconnectAudioDevice() API methods would still be desirable though,
27 because the current situation is still inconsistent and error prone.
28 - Active voices are now internally grouped to "Note" objects, instead of
29 being directly assigned to a keyboard key. This allows more fine graded
30 processing of voices, which is i.e. required for certain instrument
31 script features.
32 - Fix: Release trigger voices were not spawned on sustain pedal up
33 (CC #64) events.
34 - Fix: Release trigger voices can now also distinguish correctly between
35 note-off and sustain pedal up events.
36 - All engines: Increased ramp speed of volume smoother and pan smoother
37 (while slow rate of crossfade smoother is preserved) to allow quick
38 volume and pan changes by instrument scripts for instance.
39 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40 properly and thus were ignored for certain uses.
41 - Added new C++ API method
42 VirtualMidiDevice::SendChannelPressureToSampler().
43 - windows, 32-bit: fixed potential crashes by making sure the stack in
44 sub threads is 16-byte aligned
45 - fixed numerous compiler warnings
46 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47
48 * packaging changes:
49 - removed unnecessary dependency to libuuid
50 (originated by libgig's usage of it)
51 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52 auto detect whether it (sh/c)ould output its messages in color.
53
54 * Real-time instrument scripts:
55 - Implemented scheduler for delayed MIDI events and for suspended scripts.
56 - Built-in script function "wait()": implemented support for function's
57 "duration-us" argument, thus scripts using this function are now
58 correctly resumed after the requested amount of microseconds.
59 - Built-in script function "play_note()": implemented support for
60 function's "duration-us" argument, thus notes triggered with this
61 argument are now correctly released after the requested amount of
62 microseconds.
63 - Fix: script events were not cleared when engine channel was reset,
64 potentially causing undefined behavior.
65 - Fixed crash which happened when trying to reference an undeclared
66 variable.
67 - Built-in script function "play_note()": Added support for passing
68 special value -1 for "duration-us" argument, which will cause the
69 triggered note to be released once the original note was released.
70 - Instrument script classes now exported with the liblinuxsampler C++ API.
71 - Added new API method ScriptVM::syntaxHighlighting() which provides
72 a convenient syntax highlighting backend for external instrument
73 script editor applications.
74 - Added new C++ API class "ScriptVMFactory".
75 - Extended parser issues to provide not only first line and first
76 column, but also last line and last column of issue (thus marking
77 the precise span of the issue within the source code).
78 - Reload script automatically after being modified by an instrument
79 editor.
80 - NKSP language grammar correction: allow empty event handler bodies
81 like "on note end on".
82 - Implemented built-in script function "change_vol()".
83 - Implemented built-in script function "change_tune()".
84 - Implemented built-in script function "change_pan()".
85 - Implemented built-in script function "change_cutoff()".
86 - Implemented built-in script function "change_reso()".
87 - Implemented built-in script function "event_status()".
88 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90 "event_status()" function.
91 - NKSP language: Added support for bitwise operators ".or.", ".and."
92 and ".not.".
93 - NKSP language scanner: Fixed IDs matching to require at least one
94 character (i.e. when matching function names or variable names).
95 - NKSP language scanner: disabled unusued rules.
96 - Fixed behavior of play_note() and note_off() functions which must
97 be distinguished engine internally from "real" MIDI note on/off
98 events in order to avoid misbehaviors like hanging notes.
99 - Implemented built-in script variable "$KSP_TIMER".
100 - Implemented built-in script variable "$NKSP_REAL_TIMER".
101 - Implemented built-in script variable "$NKSP_PERF_TIMER".
102 - Implemented built-in script variable "$ENGINE_UPTIME".
103 - Implemented built-in script function "inc()".
104 - Implemented built-in script function "dec()".
105 - NKSP language fix: division expressions were evaluated too often.
106 - NKSP language fix: string concatenation operator was right
107 associative instead of left (to right).
108 - NKSP language correction: allow empty statements in entire language
109 (i.e. "if end if").
110 - Implemented built-in script function "stop_wait()".
111 - Implemented built-in script variable "$NI_CALLBACK_ID".
112 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

115 handled by the script parser).
116 - Added built-in script constant "$NI_CB_TYPE_INIT".
117 - Added built-in script constant "$NI_CB_TYPE_NOTE".
118 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 - NKSP Language: Added support for user defined script functions.
121 - Implemented built-in script function "change_attack()".
122 - Implemented built-in script function "change_decay()".
123 - Implemented built-in script function "change_release()".
124 - Fixed all change_*() built-in script functions to apply their
125 synthesis parameter changes immediately in case the respective note
126 was triggered at the same time, instead of scheduling the parameter
127 change, especially because it would cause some parameter types's
128 changes either to be ramped (i.e. change_vol()) or other types even
129 to have not effect at all (i.e. change_attack()).
130 - Implemented built-in script function "sh_left()".
131 - Implemented built-in script function "sh_right()".
132 - Implemented built-in script function "min()".
133 - Implemented built-in script function "max()".
134 - NKSP Fix: "init" event handler was not always executed when a script
135 was loaded.
136 - NKSP built-in wait() script function: abort script execution if
137 a negative or zero wait time was passed as argument (since this is
138 a common indication of a bug either of the script or even of the
139 engine, which could lead to RT instability or even worse).
140 - ScriptVM: Implemented automatic suspension of RT safety
141 threatening scripts.
142 - Provide more user friendly error messages on syntax errors.
143 - Fixed NKSP parser warning "Not a statement" when assigning an
144 initializer list to an array variable.

146 - Implemented built-in script function "in_range()".
147 - Implemented built-in script function "change_amp_lfo_depth()".
148 - Implemented built-in script function "change_amp_lfo_freq()".
149 - Implemented built-in script function "change_pitch_lfo_depth()".
150 - Implemented built-in script function "change_pitch_lfo_freq()".
151 - Implemented built-in script function "change_vol_time()".
152 - Implemented built-in script function "change_tune_time()".
153 - Implemented built-in script function "fade_in()".
154 - Implemented built-in script function "fade_out()".
155 - Fixed acceptance of wrong data type of parameters passed to built-in
156 script functions "change_vol()", "change_tune()", "change_pan()",
157 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 - Added built-in script function "get_event_par()" and implemented some
161 of its possible parameter selections.
162 - Added built-in script function "set_event_par()" and implemented some
163 of its possible parameter selections.
164 - Fixed a bunch of scheduler time related bugs.
165 - Fixed polyphonic variables not being reset to zero after usage.
166 - Built-in "ignore_event()" function: argument is now optional, like with
167 built-in function "ignore_controller()".
168 - Implemented built-in script function "change_velo()".
169 - Implemented built-in script function "change_note()".
170 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171 intuitive behavior if used in combination with "change_vol_time()" or
172 "change_tune_time()" respectively: now tuning/volume changes are only
173 assigned (without delay) immediately to a new note if the respective
174 timing function has not been called before, otherwise the volume/tuning
175 changes are automatically faded (before, only the event's time stamp was
176 relevant).
177 - Implemented built-in script function "array_equal()".
178 - Implemented built-in script function "search()".
179 - Implemented built-in script function "sort()".
180 - NKSP Fix: Never suspend "init" event handlers.
181 - Implemented built-in script function "same_region()" (currently only
182 available for gig format engine).
183 - 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 - 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 - 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 - Implemented built-in script function "change_play_pos()".
200 - 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 - NKSP language fix: Unknown characters were not handled correctly.
204 - NKSP language: Added support for "synchronized .. end synchronized"
205 code blocks.
206 - Implemented built-in script function "abort()" which allows to abort
207 another script handler by passing its callback ID.
208

210 - Fixed memory access bug of general DB access code which lead to
211 undefined behavior.
212 - Cleanup of instruments DB file creation and opening code.
213 - The instrument DB path of linuxsampler's --create-instruments-db argument

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

375 - optimized sample lookup
376 - improved support for exclusive groups (group, off_by and
377 off_mode)
378 - added support for controller triggered regions (on_locc/on_hicc)
379 - added support for loop_mode=one_shot
380 - fixed playback of 16 bit wav files on big endian CPUs
381 - added support for Ogg Vorbis sample files
382 - use loop markers from sample file if loop_start and loop_end are
383 not set in sfz file
384 - implemeted filters. Filter types: lowpass, bandpass, bandreject
385 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
386 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
387 cutoff_cc, cutoff_chanaft.
388 - bugfix: zero ampeg_sustain didn't work

577 the driver will automatically connect to other CoreMIDI clients' ports
578 (e.g. external MIDI devices being attached to the Mac)
579 - added support for MIDI note on velocity filter
580 - CoreMIDI: fixed memory deallocation error
581 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
582 virtual keyboards in frontends / instrument editors being stuck.

751 crashes and noise on such transitions).
752 - ignore missing LADSPA paths without ignoring valid LADSPA paths
753 (fixes #208)
754 - Fixed bug in LSCP grammar definition which caused a statement like
755 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
756 practically irrelevant, however it caused problems with the new LSCP
757 shell's auto completion feature).
758 - Fixed MIDI program change messages being ignored if quickly executed
759 after each other (fixes #231).
760
761 Version 1.0.0 (31 July 2009)

777 directory above)
778 - configure script fix: removed unconditional use of SSE
779 - fixed building with sqlite installed in a non-standard directory
780 - when cross-compiling, don't try to create instruments.db

782
783 * general changes:
784 - bugfix: on some POSIX systems instrument editor plugins refused to

786 (fixes bug #70, patch by Ronald Baljeu)
787 - fixed endless loop which occured when loading an instrument editor
788 plugin DLL on Windows systems failed
789 - fixed memory leaks that occurred when liblinuxsampler was unloaded
790 - optimized the SynchronizedConfig class so it doesn't wait
791 unnecessarily long after an update

794 of gigedit)
795 - added support for triggering notes by instrument editors (see above)
796 - be verbose on DLL load errors (on Linux)
797 - fixed di-harmonic triangle LFO implementation (this LFO implementation
798 is only used by very few systems, most pick the int math
799 implementation, which is usually faster)
800 - fixes for audio drivers with varying buffer sizes
801 - experimental support for running LinuxSampler as a DSSI, LV2 and
802 VST plugin
803 - notification events for stream/voice count statistics are now sent

806 multi-core and multi-cpu systems
807 - maximum voices and disk streams can now be altered at runtime
808 - fixed CPU feature detection on x86_64 (maybe fixes #108)
809 - automatic stacktrace mechanism is now turned off by default and can
810 be switched on by command line option "--stacktrace" (the automatic
811 stacktrace mechanism seems to be broken on most systems at the moment)
812 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
813 a pointer to the launched InstrumentEditor object
814 - added optional 3rd party user data parameter for following
815 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
816 InstrumentEditor::Launch(),
817 InstrumentManager::LaunchInstrumentEditor()
818 - theoretical fix: made SynchronizedConfig follow C++0x memory
819 model more strictly
820 - fixes for using large audio device buffers
821 - Windows: add the installation directory to the DLL search path
822 when loading an editor plugin (solves problems with VST and

828 max. 100 audio channels) for most audio drivers
829 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
830 opposed to the LSCP specs
831 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
832 reflected the wrong value
833 - fixed a memory management bug in ASIO driver
834 - Makefile fix: JACK_CFLAGS wasn't used
835 - JACK: use jack_client_open instead of the deprecated

849 stereo
850 - added channel routing, fxsends and midi maps to the settings
851 stored in the plugin state
852 - performance optimization of AudioChannel::MixTo() and
853 AudioChannel::CopyTo() methods using GCC vector exensions
854 (if available)
855 - ASIO fixes: avoid initializing the device twice, avoid throwing
856 exception when getting parameters from a disconnected device
857
858 * MIDI driver:
859 - added JACK MIDI driver
860 - dispatch bank select as ordinary CC as well, the user might seriously

863 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
864 CoreMidi or AU
865 - fixed mingw-w64 compilation error in MME driver
866 - made program change handling in MIDI thread real-time safe by
867 moving the logic to a non-RT thread
868 - fixed minor memory leak in ALSA driver
869
870 * instruments database:
871 - avoid time consuming samples scanning when adding instruments
872 to the instruments database
873 - added support for handling lost files in the instruments database
874 - Implemented option for adding instruments in separate directories
875 in the instruments database
876 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
877 - work-around for missing fnmatch function on Windows to make
878 instrument database compilable
879 - added instrument database support on Windows
880 works with both standalone mode and VST plugin.
881 the instruments DB file is located in
882 %USERPROFILE%\.linuxsampler\instruments.db which allows different
883 databases for each windows user
884 if no DB is present it automatically creates the .linuxsampler subdir
885 and then creates an empty DB
886 - fixed recursive import, which was broken on Windows
887
888 * Gigasampler format engine:
889 - fixed a memory leak that could happen when a channel was deleted
890 while notes were playing
891 - made it possible to load an instrument even if the audio thread
892 isn't running
893 - added partial support for the "Controller Triggered" MIDI rule,
894 enough for piano gigs with pedal noise samples
895 - minor fix: only mark FX sends as being modified if really the
896 respective FX send MIDI controller was used
897 - added support for GM global device volume SysEx message
898 (can be selected at compile time to either apply globally to the
899 whole sampler [default] or only to the sampler channels that are
900 connected to the respective MIDI input port the SysEx message arrived
901 on)
902 - bugfix: notes triggered at position 0 in the audio buffer were
903 sometimes wrongly killed in the same buffer, causing no sound to
904 be played
905 - added support for chromatic / drumkit mode Roland GS Sysex message
906 which is usally used to switch a part between chromatic sounds and
907 drumkit sounds (as opposed to their common default setting of MIDI
908 part 10 being a drumkit part and all other ones chromatic parts), in
909 LS however one can switch between the first 16 MIDI instrument maps
910 defined for the sampler
911 - made it possible to create multiple sample channels even if the
912 audio thread isn't running
913 - fixed crash when removing channel with active voices (#116)
914 - bugfix: on sample reference changes (instrument editor), only
915 un-cache the respective sample if it's really not used by any
916 sampler engine anymore
917 - re-cache samples in case they were changed by an instrument editor,
918 e.g. when a sample was added while playing (#82)
919 - fixed hanging notes which occured when note-off event had the exact
920 same time stamp as the voice's note-on event and occured both in the
921 same audio fragment cycle (fixes bug #112)
922 - added support for the "fine tune" and "pitch bend range"
923 instrument-level gig parameters
924 - fixed minor artifacts in pitch bend handling
925 - added support for GS Reset SysEx message
926 - allow gig files to use unlimited downward pitch shifting
927 - added a limit check for upward pitch shifting
928 - bugfix: sometimes, when playing a note twice fast, the second
929 note was silent
930 - fixed crash happening when a pitch bend event arrived at the
931 same time a new instrument was loading
932
933 * LSCP server:
934 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
935 react on MIDI data arriving on certain sampler channels (so far only
936 Note-On and Note-Off events are sent via this LSCP event)
937 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
938 react on MIDI data arriving on certain MIDI input devices (so far only
939 Note-On and Note-Off events are sent via this LSCP event)
940 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
941 SET DB_INSTRUMENT FILE_PATH
942 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
943 frontends to send MIDI messages to specific sampler channel
944 - added two additional fields to GET FILE INSTRUMENT INFO command -
945 KEY_BINDINGS and KEYSWITCH_BINDINGS
946 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
947 was incorrect
948 - Optimized the retrieval of the MIDI instrument mappings
949 - added new LSCP command "SET VOICES" to globally alter the maximum
950 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
951 be triggered respectively
952 - added new LSCP command "SET STREAMS" to globally alter the maximum
953 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
954 which will be triggered respectively
955 - bugfix: retry if "select" returns EINTR (this fixes a crash when
956 a gigedit file dialog is opened)
957 - close all connections when LSCPServer is deleted
958 - hard close of all sockets on exit
959 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
960 driver
961
962 * Bug fixes:
963 - fixed a crash which occurs when removing a sampler channel waiting
964 to start instrument loading after another channel
965 - fixed a crash which occurs when removing a sampler channel with
966 instrument loading in progress (bug #113)
967 - fixed termination caused by uncaught exception when adding MIDI
968 instrument with PERSISTENT load mode
969 - fixed possible iterator invalidations when resetting the sampler
970 - fixed memory leaks when issuing the following LSCP commands:
971 GET AUDIO_OUTPUT_DRIVER INFO
972 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
973 GET MIDI_INPUT_DRIVER INFO
974 GET MIDI_INPUT_DRIVER_PARAMETER INFO
975 - fixed possible compilation error when sqlite is not present
976 - fixed orphaned pointers when setting maximum voices limit (bug #118)
977 - fixed crash when changing the audio output device of a sampler
978 channel with loaded instrument and start playing notes
979 - fixed endless loop in Engine::SuspendAll() (bug #120)
980 - fixed a low-level atomic load function that was broken on 64-bit
981 PowerPC, which probably could cause crashes on that platform
982 - fixed a memory management error which could cause a crash when a
983 plugin was unloaded
984 - bugfix: two private structs had the same name, which could cause
985 problems if the linker chose the wrong constructor
986 - fixed low-level ConditionServer usage bug that caused lockups on
987 Windows
988
989
990 Version 0.5.1 (6 December 2007)
991
992 * packaging changes:
993 - added autoconf checks for pthread library
994 - added autoconf check for pthread bug found on certain NPTL-enabled
995 glibc versions (see Gentoo bug report #194076)
996 - added autoconf checks for MS Windows
997
998 * general changes:
999 - bugfix: the thread used by an editor plugin didn't die when the
1000 editor closed
1001 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1002 out all the space. operator--() did not apply size_mask after
1003 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1004 order to avoid problems with the _NonVolatileReader functions.
1005 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1006 GetWriteSpace(). Since this function is currently only used in
1007 the stream's qsort() compare function, it didn't trigger any
1008 bugs.
1009 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1010 24bit mode too. Faster method to read 24bit words on little
1011 endian machines (x86): replaced 3 byte reads + shifts with a 1
1012 unaligned 32bit read and shift
1013 - experimental support for MS Windows (MIDI input via MME, AUDIO
1014 output via ASIO)
1015 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1016 - support for monitoring the total number of active disk streams
1017 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1018 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1019
1020 * AUDIO driver:
1021 - added Windows ASIO low latency audio driver
1022
1023 * MIDI driver:
1024 - added MME Windows MIDI driver
1025
1026 * LSCP server:
1027 - added support for Windows style path / filenames, however with
1028 forward slash path separators instead of backslash
1029 (i.e. "C:/foo/bar.gig")
1030 - allow naughty liblscp to send non-string device parameters within
1031 apostrophes as well
1032 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1033 "LIST FILE INSTRUMENTS <file>" and
1034 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1035 about an arbitrary instrument file on the system where the sampler is
1036 running on
1037
1038 Version 0.5.0 (15 October 2007)
1039
1040 * packaging changes:
1041 - config.h is not going to be installed along with liblinuxsampler's
1042 API header files anymore
1043 - only the API relevant header (and source) files will be exported to
1044 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1045 - added completely new XCode project files for Mac OSX which is now
1046 capable to execute our autoconf environment, thus no need anymore
1047 to maintain the compile time configuration file (osx/version.h) for
1048 OSX manually (patch by Toshi Nagata)
1049 - fixed buggy boolean --enable-foo / --disable-foo configure script
1050 parameters
1051 - global.h now only covers global definitions that are needed for the
1052 C++ API header files, all implementation internal global definitions
1053 are now in global_private.h
1054 - atomic.h is not exposed to the C++ API anymore
1055 - no need to include config.h anymore for using LS's API header files
1056 - fixed warnings in API doc generation
1057
1058 * general changes:
1059 - replaced the old, confusing MIDI program change mechanism by a
1060 flexible MIDI instrument mapper which allows to map arbitrary
1061 (MIDI bank, MIDI program) pairs with arbitrary
1062 (engine type, instrument file, file index) triplets which will be
1063 loaded on the respective channel when such MIDI program change
1064 messages arrive, beside that, each entry allows to define a life-time
1065 strategy for the instrument, so the user can define whether the
1066 instrument should i.e. be permanently loaded (to be able to switch
1067 quickly among sounds) or i.e. loaded just on demand when the
1068 respective program change arrives (to safe RAM space), as well as a
1069 global volume factor for each entry, so the user can adjust the volume
1070 dynamic of his mapped instrument collection without having to modify
1071 the instrument files, also one can manage arbitrary amount of such
1072 MIDI instrument maps and assign each sampler channel individually
1073 a certain map, so that i.e. separation of normal instruments and
1074 drumkits is possible
1075 - new notification events for tracking changes to audio/MIDI devices,
1076 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1077 - sampler was limited to load max. 200 instruments in the background
1078 due to a constant size RingBuffer FIFO which is now replaced by a
1079 dynamic (unlimited) size std::list FIFO
1080 - added FX sends, these allow to route audio signals to arbitrary audio
1081 output channels for being processed by external effect processors
1082 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1083 controllers
1084 - global (sampler wide) volume can now be controlled at runtime
1085 - Implemented new, improved notification system
1086 - fixed compilation errors regarding OSX
1087 (patch by Toshi Nagata)
1088 - implemented instruments database
1089 - added support for escape sequences to the instruments database
1090 - added highly experimental support for on-the-fly instrument editing
1091 within the sampler's process (by using instrument editor plugins),
1092 you'll notice the new "Registered instrument editors:" message on
1093 startup, added a new LSCP command:
1094 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1095 to spawn a matching instrument editor for the instrument on the
1096 given sampler channel, the plugin path can be overridden at compile
1097 time with ./configure --enable-plugin-dir=/some/dir
1098 - added experimental code for synchronizing instrument editors hosted
1099 in the sampler's process to safely edit instruments while playing
1100 without a crash (hopefully) by either suspending single regions
1101 wherever possible or if unavoidable whole engine(s)
1102 - fixed several issues in fundamental "Thread" class: set scheduling
1103 policy and priority on thread level, set a minimum stack size for
1104 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1105 threads simply inherited properties of starting thread instead of
1106 setting their own policy and priority
1107 - minor fix in our automatic stack trace mechanism on crashes, the
1108 main process did not wait for the stack trace process to finish
1109 its output
1110 - fixed some minor memory leaks
1111 - reenabled assembly features support, at the moment only for
1112 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1113 - minor assembly fix in x86 features detection (don't use the PIC
1114 register, to avoid relocations in the text segment at runtime)
1115 - POSIX callback functions of Thread.h are hidden
1116
1117 * MIDI driver:
1118 - dispatch bank select (MSB and LSB) messages
1119
1120 * audio driver:
1121 - the ALSA audio output driver parameters now reflect the correct
1122 parameter value ranges for the respective selected sound card
1123 (patch by Till Wimmer, a bit fixed and extended)
1124
1125 * Gigasampler format engine:
1126 - if a filter is used and EG2 finishes before EG1, let the voice
1127 die when EG2 has finished (this fixes a problem with clicks and
1128 voice starvation for some gigs)
1129 - playback is no longer disabled during instrument loading
1130 - all notes playing on a channel that changes its instrument keep
1131 playing with the old instrument until they get a note off
1132 command
1133 - EG fix: a release value of zero could cause noises or crash
1134 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1135 - EG fine tuning: when attack is zero the EG starts at a level
1136 above max sustain level, which means that there is a decay phase
1137 even if sustain is 100%
1138 - more EG fixes: the level could sometimes go below zero and cause
1139 noises or crashes
1140 - minor fix of EGDecay (patch by Toshi Nagata)
1141 - fixed compiler error when --enable-override-filter-type was
1142 supplied to the configure script (fixes #46)
1143 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1144 instead of a fix value
1145 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1146 127 (solo mode) only kill voices if the respective mode really
1147 changed
1148
1149 * LSCP server:
1150 - fixed compile time error for old Bison versions
1151 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1152 - parser now supports extended ASCII character set
1153 (up to ASCII code 255, i.e. includes now umlauts and accents)
1154 - filename arguments in LSCP commands now allow to use escape
1155 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1156 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1157 code value like \xf2) (fixes bug #24)
1158 - the following LSCP commands now also support escape sequences for at
1159 least one of their text-based parameters (i.e. name, description):
1160 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1161 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1162 "SET DB_INSTRUMENT_DIRECTORY NAME",
1163 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1164 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1165 "FIND DB_INSTRUMENT_DIRECTORIES"
1166 - returns verbose syntax errors (line and column where syntax error
1167 occured, the unexpected character and the actually expected, possible
1168 character(s), the latter only if less than 5 possibilities)
1169 - made sure that LSCP syntax is not affected by gigedit locale
1170 settings
1171 - bugfix regarding strings parameter lists: all comma separated lists
1172 of strings were treated as being one string containing commas
1173 (fixes #57)
1174
1175 * Bug fixes:
1176 - fixed crash occurring on certain LSCP scripts (Bug 39)
1177 - another thread safety fix for lscp "load engine" and "set
1178 channel audio output device"
1179 - fixed a crash which occurs when reassigning the same engine
1180 on a sampler channel with connected MIDI device
1181 - fixed a crash which occurs when changing the number of ports of a MIDI
1182 device connected to a sampler channel to number less then or equal
1183 to the index of the port to which the sampler channel is connected.
1184 - The previous bindings were not been disconnected when altering
1185 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1186 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1187 - The active stream/voice count statistic was incorrect.
1188 - notification events were not been sent for some sampler
1189 channel changes
1190 - added default min and max values to restrict the number of allowed
1191 audio output channels and MIDI input ports
1192 - the connection to the PCM interface is now closed when destroying
1193 an audio output device
1194 - files with slash in their path or filename could not be loaded
1195
1196 * test cases:
1197 - updated and fixed (haven't been touched in a while)
1198
1199 Version 0.4.0 (24 November 2006)
1200
1201 * packaging changes:
1202 - changed deprecated copyright attribute to license; added ldconfig
1203 to post-(un)install steps; added devel package for liblinuxsampler;
1204 to linuxsampler.spec (RPM)
1205 - install necessary development header files for allowing 3rd party
1206 applications to link against liblinuxsampler
1207 - liblinuxsampler's API documentation can be generated with 'make docs'
1208 (Doxygen required)
1209 - added benchmark to automatically detect the best triangle LFO
1210 implementation (currently either an integer math solution or a
1211 di-harmonic approximation), automatic detection can be overriden
1212 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1213 configure script argument though (mandatory for cross-compilation)
1214 - do not automatically pick optimized gcc flags if the user already
1215 provided some on his own (as CXXFLAGS)
1216 - added compile time option to disable processing of All-Notes-Off MIDI
1217 messages
1218 - added compile time options to allow disabling the various audio and
1219 MIDI drivers
1220 - fixed automatic GCC CPU switch detection on PPC
1221 (patch by Ebrahim Mayat)
1222
1223 * Gigasampler format engine:
1224 - extensive synthesis optimization
1225 (reimplementation of EGs and LFO(s), removed synthesis parameter
1226 prerendering and the synthesis parameter matrix in general, splitting
1227 each audio fragment into subfragments now where each subfragment uses
1228 constant pitch and filter coefficients. The volume coefficient is
1229 linearly interpolated inside a subfragment, unless
1230 --disable-interpolate-volume is set.)
1231 - fine tuning of the EG modulation parameters
1232 - improved filter cutoff calculation by adding support for the
1233 following gig parameters: Cutoff freq (used when no cutoff
1234 controller is defined), Control invert, Minimum cutoff, Velocity
1235 curve and Velocity range. The keyboard tracking now scales
1236 cutoff frequency instead of resonance.
1237 - added support for gig parameter Resonance.
1238 - fixed bug in sysex handling (patch by Juan Linietsky)
1239 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1240 which can be overridden with --enable-global-attenuation
1241 - EG fixes: made the length of "attack hold" stage more
1242 accurate. Release stage can now start before attack stage
1243 ends. Cancel release didn't work when sustain was zero. Attack
1244 time now has a minimal value to prevent clicks.
1245 - fixed pitch changes larger than one octave
1246 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1247 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1248 all modes can be altered via standard GM messages, that is CC5 for
1249 altering portamento time, CC65 for enabling / disabling portamento
1250 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1251 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1252 parameter) and crossfade
1253 - added support for the "attenuation controller threshold" gig
1254 parameter
1255 - added smoothing of volume changes caused by control change
1256 messages
1257 - sample loop parameters are now taken from the DimensionRegion
1258 instead of the wave chunk
1259 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1260 not equal to a power of two
1261 - reimplementation of the filter algorithm. The new filter is more
1262 accurate and supports all gig filter types, including bandreject
1263 and lowpass turbo.
1264 - real support for 24 bit samples - samples are not truncated to
1265 16 bits anymore
1266 - support for aftertouch (channel pressure, not polyphonic
1267 aftertouch)
1268 - LFO1 behaviour fixed (dampening from max volume instead of
1269 amplifying from 0)
1270
1271 * LSCP server:
1272 - fixed application exit on broken pipe error (fixes bug #20)
1273 - fixed the notification messages delay due to lack of
1274 network activity (fixes bug #26)
1275 - fixed parser bug which occured on space(s) within device parameters
1276 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1277
1278 * audio driver:
1279 - added aRts audio output driver (by no means RT safe)
1280
1281 * MIDI driver:
1282 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1283 messages several times instead of once
1284 - API extension for MIDI drivers which already supply exact time stamps
1285 for events (i.e. for offline rendering based MIDI drivers)
1286 - added checks for bad MIDI data
1287
1288 * linuxsampler application:
1289 - show available sampler engine types on startup
1290
1291 * general changes:
1292 - support for muting sampler channels and solo mode of the same, two new
1293 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1294 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1295 introduced for this, the behavior is the same like on a mixer console
1296 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1297 --enable-process-muted-channels which can be used to enable the
1298 processing of muted channels.
1299 - support for sostenuto pedal
1300 - support for monitoring the total number of active voices
1301 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1302 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1303 - fixed some memory management errors
1304 - fixed some concurrency problems that could lead to crashes when
1305 LSCP commands were executed
1306 - fixed crash when instrument loading failed previously on the same
1307 sampler channel (fixes bug #36)
1308
1309 Version 0.3.3 (15 July 2005)
1310
1311 * packaging changes:
1312 - fixed compilation with gcc 4.0
1313
1314 * Gigasampler format engine:
1315 - LFO preprocessing was performed even though the respective LFO was
1316 disabled by the instrument patch (minor efficiency fix)
1317 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1318 for volume ramp downs in the same fragment (needed for current voice
1319 stealing implementation) then simply inform the user with a warning
1320 about possible click sounds and reduce the volume ramp down
1321 appropriately instead of cancelling the audio device connection
1322
1323 Version 0.3.2 (24 June 2005)
1324
1325 * packaging changes:
1326 - updated autotools build files to compile on OS X
1327 (conditional compilation of CoreMIDI and MidiShare drivers)
1328 - hand-crafted assembly optimization code can be disabled with
1329 './configure --disable-asm' (definitely not recommended)
1330 - fixed 'make dist' rule to include all necessary files
1331 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1332 (due to 'dist-bzip2' automake option)
1333
1334 * Gigasampler format engine:
1335 - support for the gig parameters for "release velocity response" curves
1336 - fine tuning of the EGADSR envelope
1337 - volume of release triggered samples now depends on note-on velocity,
1338 note length and gig parameter "release trigger decay" instead of
1339 note-off velocity.
1340 - revised voice stealing
1341 (fixes crash and endless loop caused by voice stealing)
1342 - don't reset scale tuning on instrument or audio output device change
1343 - handle key group conflicts right at the beginning of each fragment
1344 instead of when the respective voice is actually launched
1345 (fixes undefined behavior if stolen voices belonged to a key group -
1346 this case was followed by a "killed voice survived" error message)
1347 - fixed minor issue with null/silence samples
1348 (those stole voices even though they don't need a voice at all which
1349 resulted in "voice stealing didn't work out" messages)
1350 - don't reset volume, pan, pitch and MIDI controller values on
1351 instrument or audio output device change

1358 * linuxsampler application:
1359 - added command line parameters --lscp-addr and --lscp-port to override
1360 default IP address and port of LSCP server
