File size: 73667 byte(s)
* NKSP language fix: Unknown characters were not handled correctly.
* Bumped version (2.0.0.svn59).

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 "$NKSP_IGNORE_WAIT".
114 - Added support for read-only built-in variables (respectively
115 handled by the script parser).
116 - Added built-in script constant "$NI_CB_TYPE_INIT".
117 - Added built-in script constant "$NI_CB_TYPE_NOTE".
118 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 - NKSP Language: Added support for user defined script functions.
121 - Implemented built-in script function "change_attack()".
122 - Implemented built-in script function "change_decay()".
123 - Implemented built-in script function "change_release()".
124 - Fixed all change_*() built-in script functions to apply their
125 synthesis parameter changes immediately in case the respective note
126 was triggered at the same time, instead of scheduling the parameter
127 change, especially because it would cause some parameter types's
128 changes either to be ramped (i.e. change_vol()) or other types even
129 to have not effect at all (i.e. change_attack()).
130 - Implemented built-in script function "sh_left()".
131 - Implemented built-in script function "sh_right()".
132 - Implemented built-in script function "min()".
133 - Implemented built-in script function "max()".
134 - NKSP Fix: "init" event handler was not always executed when a script
135 was loaded.
136 - NKSP built-in wait() script function: abort script execution if
137 a negative or zero wait time was passed as argument (since this is
138 a common indication of a bug either of the script or even of the
139 engine, which could lead to RT instability or even worse).
140 - ScriptVM: Implemented automatic suspension of RT safety
141 threatening scripts.
142 - Provide more user friendly error messages on syntax errors.
143 - Fixed NKSP parser warning "Not a statement" when assigning an
144 initializer list to an array variable.
145 - Implemented built-in script array variable "%ALL_EVENTS".
146 - Implemented built-in script function "in_range()".
147 - Implemented built-in script function "change_amp_lfo_depth()".
148 - Implemented built-in script function "change_amp_lfo_freq()".
149 - Implemented built-in script function "change_pitch_lfo_depth()".
150 - Implemented built-in script function "change_pitch_lfo_freq()".
151 - Implemented built-in script function "change_vol_time()".
152 - Implemented built-in script function "change_tune_time()".
153 - Implemented built-in script function "fade_in()".
154 - Implemented built-in script function "fade_out()".
155 - Fixed acceptance of wrong data type of parameters passed to built-in
156 script functions "change_vol()", "change_tune()", "change_pan()",
157 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 - Added built-in script function "get_event_par()" and implemented some
161 of its possible parameter selections.
162 - Added built-in script function "set_event_par()" and implemented some
163 of its possible parameter selections.
164 - Fixed a bunch of scheduler time related bugs.
165 - Fixed polyphonic variables not being reset to zero after usage.
166 - Built-in "ignore_event()" function: argument is now optional, like with
167 built-in function "ignore_controller()".
168 - Implemented built-in script function "change_velo()".
169 - Implemented built-in script function "change_note()".
170 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171 intuitive behavior if used in combination with "change_vol_time()" or
172 "change_tune_time()" respectively: now tuning/volume changes are only
173 assigned (without delay) immediately to a new note if the respective
174 timing function has not been called before, otherwise the volume/tuning
175 changes are automatically faded (before, only the event's time stamp was
176 relevant).
177 - Implemented built-in script function "array_equal()".
178 - Implemented built-in script function "search()".
179 - Implemented built-in script function "sort()".
180 - NKSP Fix: Never suspend "init" event handlers.
181 - Implemented built-in script function "same_region()" (currently only
182 available for gig format engine).
183 - 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
205 * Instruments DB:
206 - Fixed memory access bug of general DB access code which lead to
207 undefined behavior.
208 - Cleanup of instruments DB file creation and opening code.
209 - The instrument DB path of linuxsampler's --create-instruments-db argument
210 is now optional, if it is missing, then a default location is used.
211 - Added support for scanning SFZ (.sfz) files.
212 - Added support for scanning Sound Font (.sf2) files.
213 - Fixed undefined DB transaction behavior.

253 in order to get rid of warnings from automake 1.14
254
255 * general changes:
256 - Refactoring: moved the independent code from
257 the Gigasampler format engine to base classes
258 - command line option '--profile' is currently disabled, since the
259 respective profiling code is currently broken
260 - Introduced support for optional environment variable
261 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
262 where the sampler shall look for instrument editor plugins
263 (patch by Luis Garrido, slightly modified).
264 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
265 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
266 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
267 note (in this implementation of the sampler its simply hard routed to
268 the 1st effect send of the sampler channel, no matter what the actual
269 effect type is)
270 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
271 note (in this implementation of the sampler its simply hard routed to
272 the 2nd effect send of the sampler channel, no matter what the actual
273 effect type is)
274 - implemented support for internal LADSPA effects
275 - raised limit of program change queue from 100 to 512
276 (as suggested by Alex Stone)
277 - implemented sine LFO, pulse LFO and saw LFO
278 - experimental support for per voice equalization
279 - added command line option --exec-after-init
280 - Introduced new C++ API method:
281 EngineChannel::InstrumentFileName(int index)
282 allowing to retrieve the whole list of files used for the loaded
283 instrument on an engine channel (a.k.a. part). Some GigaStudio
284 instruments for example are splitted over several files like
285 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
286 - Added new C++ API method Sampler::GetGlobalMaxVoices().
287 - Added new C++ API method Sampler::GetGlobalMaxStreams().
288 - Added new C++ API method Sampler::SetGlobalMaxVoices().
289 - Added new C++ API method Sampler::SetGlobalMaxStreams().
290 - Various "const" and "restrict" optimizations.
291 - all engines: add pan CC value to instrument pan parameter before
292 applying panning, instead of using two separate pan functions in
293 series (#182)
294 - added a lock guard class for exception safe mutex handling and
295 used it everywhere appropriate
296 - Immediately apply scale tuning changes to active voices.
297 - Exposed scale tuning to C++ API (along to the already existing standard
298 SysEx way).
299 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
300 and broken for ppc64. (Seq_cst loads and stores are actually not
301 used in LS, so the bug wasn't noticable.)
302 - lsatomic.h: added ARMv7 support
303 - Added support for multiple MIDI input ports per sampler channel (and
304 added various new C++ methods for this new feature / design change, old
305 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
306 as deprecated but are still there and should provide full behavior
307 backward compatibility).
308 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
309 unsafe and caused compilation error with clang 2.x).
310 - Bugfix: only process the latest MIDI program change event.
311 - Introducing the LSCP shell, which provides convenient control of the
312 sampler from the command line by providing LSCP aware features.
313 - VirtualMidiDevice: Added support for program change.
314 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
315 - VirtualMidiDevice: Added support for pitch bend.
316 - Aftertouch: extended API to explicitly handle channel pressure and
317 polyphonic key pressure events (so far polyphonic pressure was not
318 supported at all, and channel pressure was rerouted as CC128 but not
319 used so far).
320 - Added initial support for real-time instrument scripts. The script VM
321 code is shared by all sampler engine implemementations, however only the
322 gig file format currently provides support for storing instrument scripts
323 (as LinuxSampler extension to the original GigaStudio 4 format).
324
325 * Gigasampler format engine:
326 - implemented the "round robin keyboard" dimension
327 - fixed round robin and random dimensions for cases when number of
328 dimension zones is not a power of two
329 - made round robin use a counter for each region instead of each
330 key
331 - bugfix: pitch LFO controller "internal+aftertouch" was broken
332 - bugfix: filter keyboard tracking was broken
333 - filter performance fix (an unnecessary copy was made of the
334 filter parameters in each sub fragment)
335 - handle special case when pan parameter in gig file has max or
336 min value
337 - Exclusive Groups: don't ever stop voices of the same note,
338 doesn't sound naturally with a drumkit
339 - fixed EG1 modulation when attack or release is zero
340 - Fixed support for 'aftertouch' attenuation controller.
341 - Fixed crash that happened with velocity split sounds under certain
342 conditions (see also previous commit on libgig).
343 - fixed behaviour of filter LFO
344
345 * SFZ format engine:
346 - Initial implementation (not usable yet)
347 - added support for v2 multiple stage envelope generators
348 - added a fine-tuned v1 envelope generator instead of using the
349 one from the gig engine
350 - fixed memory leak and memory handling errors
351 - added support for trigger=first, trigger=legato and sw_previous
352 - allow non-numerical key values ("C#4" for example)
353 - "key" opcode now sets pitch_keycenter too
354 - fixed error when unloading instrument with same sample used by
355 multiple regions
356 - added some opcode aliases, like loopmode for loop_mode, to be
357 more compatible
358 - added support for trigger=release and rt_decay

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

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

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

773 directory above)
774 - configure script fix: removed unconditional use of SSE
775 - fixed building with sqlite installed in a non-standard directory
776 - when cross-compiling, don't try to create instruments.db
777 - fix for new mingw-w64 version, which has usleep
778
779 * general changes:
780 - bugfix: on some POSIX systems instrument editor plugins refused to
781 load as we used a non-portable Linux specific struct field
782 (fixes bug #70, patch by Ronald Baljeu)
783 - fixed endless loop which occured when loading an instrument editor
784 plugin DLL on Windows systems failed
785 - fixed memory leaks that occurred when liblinuxsampler was unloaded
786 - optimized the SynchronizedConfig class so it doesn't wait
787 unnecessarily long after an update

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

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

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

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

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