Revision 3290 - (show annotations) (download)
Fri Jun 23 12:24:58 2017 UTC (6 years, 9 months ago) by schoenebeck
File size: 74342 byte(s)
* Revised fundamental C++ classes "Thread", "Mutex" and
  "Condition" which fixes potential undefined behavior
  (note: this addresses mainly the POSIX implementation,
   Win32 is untested yet and would also need an update).
* Bumped version (2.0.0.svn64).

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 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
48 fixes potential undefined behavior.
49
50 * packaging changes:
51 - removed unnecessary dependency to libuuid
52 (originated by libgig's usage of it)
53 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
54 auto detect whether it (sh/c)ould output its messages in color.
55
56 * Real-time instrument scripts:
57 - Implemented scheduler for delayed MIDI events and for suspended scripts.
58 - Built-in script function "wait()": implemented support for function's
59 "duration-us" argument, thus scripts using this function are now
60 correctly resumed after the requested amount of microseconds.
61 - Built-in script function "play_note()": implemented support for
62 function's "duration-us" argument, thus notes triggered with this
63 argument are now correctly released after the requested amount of
64 microseconds.
65 - Fix: script events were not cleared when engine channel was reset,
66 potentially causing undefined behavior.
67 - Fixed crash which happened when trying to reference an undeclared
68 variable.
69 - Built-in script function "play_note()": Added support for passing
70 special value -1 for "duration-us" argument, which will cause the
71 triggered note to be released once the original note was released.
72 - Instrument script classes now exported with the liblinuxsampler C++ API.
73 - Added new API method ScriptVM::syntaxHighlighting() which provides
74 a convenient syntax highlighting backend for external instrument
75 script editor applications.
76 - Added new C++ API class "ScriptVMFactory".
77 - Extended parser issues to provide not only first line and first
78 column, but also last line and last column of issue (thus marking
79 the precise span of the issue within the source code).
80 - Reload script automatically after being modified by an instrument
81 editor.
82 - NKSP language grammar correction: allow empty event handler bodies
83 like "on note end on".
84 - Implemented built-in script function "change_vol()".
85 - Implemented built-in script function "change_tune()".
86 - Implemented built-in script function "change_pan()".
87 - Implemented built-in script function "change_cutoff()".
88 - Implemented built-in script function "change_reso()".
89 - Implemented built-in script function "event_status()".
90 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
91 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
92 "event_status()" function.
93 - NKSP language: Added support for bitwise operators ".or.", ".and."
94 and ".not.".
95 - NKSP language scanner: Fixed IDs matching to require at least one
96 character (i.e. when matching function names or variable names).
97 - NKSP language scanner: disabled unusued rules.
98 - Fixed behavior of play_note() and note_off() functions which must
99 be distinguished engine internally from "real" MIDI note on/off
100 events in order to avoid misbehaviors like hanging notes.
101 - Implemented built-in script variable "$KSP_TIMER".
102 - Implemented built-in script variable "$NKSP_REAL_TIMER".
103 - Implemented built-in script variable "$NKSP_PERF_TIMER".
104 - Implemented built-in script variable "$ENGINE_UPTIME".
105 - Implemented built-in script function "inc()".
106 - Implemented built-in script function "dec()".
107 - NKSP language fix: division expressions were evaluated too often.
108 - NKSP language fix: string concatenation operator was right
109 associative instead of left (to right).
110 - NKSP language correction: allow empty statements in entire language
111 (i.e. "if end if").
112 - Implemented built-in script function "stop_wait()".
113 - Implemented built-in script variable "$NI_CALLBACK_ID".
114 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
115 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
116 - Added support for read-only built-in variables (respectively
117 handled by the script parser).
118 - Added built-in script constant "$NI_CB_TYPE_INIT".
119 - Added built-in script constant "$NI_CB_TYPE_NOTE".
120 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
121 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
122 - NKSP Language: Added support for user defined script functions.
123 - Implemented built-in script function "change_attack()".
124 - Implemented built-in script function "change_decay()".
125 - Implemented built-in script function "change_release()".
126 - Fixed all change_*() built-in script functions to apply their
127 synthesis parameter changes immediately in case the respective note
128 was triggered at the same time, instead of scheduling the parameter
129 change, especially because it would cause some parameter types's
130 changes either to be ramped (i.e. change_vol()) or other types even
131 to have not effect at all (i.e. change_attack()).
132 - Implemented built-in script function "sh_left()".
133 - Implemented built-in script function "sh_right()".
134 - Implemented built-in script function "min()".
135 - Implemented built-in script function "max()".
136 - NKSP Fix: "init" event handler was not always executed when a script
137 was loaded.
138 - NKSP built-in wait() script function: abort script execution if
139 a negative or zero wait time was passed as argument (since this is
140 a common indication of a bug either of the script or even of the
141 engine, which could lead to RT instability or even worse).
142 - ScriptVM: Implemented automatic suspension of RT safety
143 threatening scripts.
144 - Provide more user friendly error messages on syntax errors.
145 - Fixed NKSP parser warning "Not a statement" when assigning an
146 initializer list to an array variable.

148 - Implemented built-in script function "in_range()".
149 - Implemented built-in script function "change_amp_lfo_depth()".
150 - Implemented built-in script function "change_amp_lfo_freq()".
151 - Implemented built-in script function "change_pitch_lfo_depth()".
152 - Implemented built-in script function "change_pitch_lfo_freq()".
153 - Implemented built-in script function "change_vol_time()".
154 - Implemented built-in script function "change_tune_time()".
155 - Implemented built-in script function "fade_in()".
156 - Implemented built-in script function "fade_out()".
157 - Fixed acceptance of wrong data type of parameters passed to built-in
158 script functions "change_vol()", "change_tune()", "change_pan()",
159 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
160 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
161 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
162 - Added built-in script function "get_event_par()" and implemented some
163 of its possible parameter selections.
164 - Added built-in script function "set_event_par()" and implemented some
165 of its possible parameter selections.
166 - Fixed a bunch of scheduler time related bugs.
167 - Fixed polyphonic variables not being reset to zero after usage.
168 - Built-in "ignore_event()" function: argument is now optional, like with
169 built-in function "ignore_controller()".
170 - Implemented built-in script function "change_velo()".
171 - Implemented built-in script function "change_note()".
172 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
173 intuitive behavior if used in combination with "change_vol_time()" or
174 "change_tune_time()" respectively: now tuning/volume changes are only
175 assigned (without delay) immediately to a new note if the respective
176 timing function has not been called before, otherwise the volume/tuning
177 changes are automatically faded (before, only the event's time stamp was
178 relevant).
179 - Implemented built-in script function "array_equal()".
180 - Implemented built-in script function "search()".
181 - Implemented built-in script function "sort()".
182 - NKSP Fix: Never suspend "init" event handlers.
183 - Implemented built-in script function "same_region()" (currently only
184 available for gig format engine).
185 - Added built-in script constant "$NKSP_LINEAR".
186 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
187 - Implemented built-in script function "change_vol_curve()".
188 - Implemented built-in script function "change_tune_curve()".
189 - built-in "play_note()" function now supports a sample playback start
190 offset with argument 3, where special value -1 means to use the regular
191 sample offset as defined by the instrument file.
192 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
193 - Built-in variable $EVENT_NOTE is now a read-only variable.
194 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
195 - built-in "play_note()" function now accepts -2 for its fourth argument
196 (note duration) which means the life time of the note shall be sticked
197 to the requested note number of argument 1.
198 - Fix: built-in "play_note()" function now returns 0 as result value if
199 -1 was passed for its fourth argument (note duration) and the respective
200 parent note is already gone.
201 - Implemented built-in script function "change_play_pos()".
202 - NKSP language: Added support for user declared const array variables.
203 - NKSP language: Raise parser warning if array variable is accessed with
204 an index that exceeds the array's size.
205 - NKSP language fix: Unknown characters were not handled correctly.
206 - NKSP language: Added support for "synchronized .. end synchronized"
207 code blocks.
208 - Implemented built-in script function "abort()" which allows to abort
209 another script handler by passing its callback ID.
210 - Fixed potential memory access bug and potential undefined behavior of
211 "init" event handlers.
212 - Print a time stamp along to each call of built-in function "message()".
213 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
214 to retrieve all code blocks filtered out by the preprocessor.
215
216 * Instruments DB:
217 - Fixed memory access bug of general DB access code which lead to
218 undefined behavior.
219 - Cleanup of instruments DB file creation and opening code.
220 - The instrument DB path of linuxsampler's --create-instruments-db argument
221 is now optional, if it is missing, then a default location is used.
222 - Added support for scanning SFZ (.sfz) files.
223 - Added support for scanning Sound Font (.sf2) files.
224 - Fixed undefined DB transaction behavior.

264 in order to get rid of warnings from automake 1.14
265
266 * general changes:
267 - Refactoring: moved the independent code from
268 the Gigasampler format engine to base classes
269 - command line option '--profile' is currently disabled, since the
270 respective profiling code is currently broken
271 - Introduced support for optional environment variable
272 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
273 where the sampler shall look for instrument editor plugins
274 (patch by Luis Garrido, slightly modified).
275 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
276 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
277 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
278 note (in this implementation of the sampler its simply hard routed to
279 the 1st effect send of the sampler channel, no matter what the actual
280 effect type is)
281 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
282 note (in this implementation of the sampler its simply hard routed to
283 the 2nd effect send of the sampler channel, no matter what the actual
284 effect type is)
285 - implemented support for internal LADSPA effects
286 - raised limit of program change queue from 100 to 512
287 (as suggested by Alex Stone)
288 - implemented sine LFO, pulse LFO and saw LFO
289 - experimental support for per voice equalization
290 - added command line option --exec-after-init
291 - Introduced new C++ API method:
292 EngineChannel::InstrumentFileName(int index)
293 allowing to retrieve the whole list of files used for the loaded
294 instrument on an engine channel (a.k.a. part). Some GigaStudio
295 instruments for example are splitted over several files like
296 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
297 - Added new C++ API method Sampler::GetGlobalMaxVoices().
298 - Added new C++ API method Sampler::GetGlobalMaxStreams().
299 - Added new C++ API method Sampler::SetGlobalMaxVoices().
300 - Added new C++ API method Sampler::SetGlobalMaxStreams().
301 - Various "const" and "restrict" optimizations.
302 - all engines: add pan CC value to instrument pan parameter before
303 applying panning, instead of using two separate pan functions in
304 series (#182)
305 - added a lock guard class for exception safe mutex handling and
306 used it everywhere appropriate
307 - Immediately apply scale tuning changes to active voices.
308 - Exposed scale tuning to C++ API (along to the already existing standard
309 SysEx way).
310 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
311 and broken for ppc64. (Seq_cst loads and stores are actually not
312 used in LS, so the bug wasn't noticable.)
313 - lsatomic.h: added ARMv7 support
314 - Added support for multiple MIDI input ports per sampler channel (and
315 added various new C++ methods for this new feature / design change, old
316 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
317 as deprecated but are still there and should provide full behavior
318 backward compatibility).
319 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
320 unsafe and caused compilation error with clang 2.x).
321 - Bugfix: only process the latest MIDI program change event.
322 - Introducing the LSCP shell, which provides convenient control of the
323 sampler from the command line by providing LSCP aware features.
324 - VirtualMidiDevice: Added support for program change.
325 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
326 - VirtualMidiDevice: Added support for pitch bend.
327 - Aftertouch: extended API to explicitly handle channel pressure and
328 polyphonic key pressure events (so far polyphonic pressure was not
329 supported at all, and channel pressure was rerouted as CC128 but not
330 used so far).
331 - Added initial support for real-time instrument scripts. The script VM
332 code is shared by all sampler engine implemementations, however only the
333 gig file format currently provides support for storing instrument scripts
334 (as LinuxSampler extension to the original GigaStudio 4 format).
335
336 * Gigasampler format engine:
337 - implemented the "round robin keyboard" dimension
338 - fixed round robin and random dimensions for cases when number of
339 dimension zones is not a power of two
340 - made round robin use a counter for each region instead of each
341 key
342 - bugfix: pitch LFO controller "internal+aftertouch" was broken
343 - bugfix: filter keyboard tracking was broken
344 - filter performance fix (an unnecessary copy was made of the
345 filter parameters in each sub fragment)
346 - handle special case when pan parameter in gig file has max or
347 min value
348 - Exclusive Groups: don't ever stop voices of the same note,
349 doesn't sound naturally with a drumkit
350 - fixed EG1 modulation when attack or release is zero
351 - Fixed support for 'aftertouch' attenuation controller.
352 - Fixed crash that happened with velocity split sounds under certain
353 conditions (see also previous commit on libgig).
354 - fixed behaviour of filter LFO
355
356 * SFZ format engine:
357 - Initial implementation (not usable yet)
358 - added support for v2 multiple stage envelope generators
359 - added a fine-tuned v1 envelope generator instead of using the
360 one from the gig engine
361 - fixed memory leak and memory handling errors
362 - added support for trigger=first, trigger=legato and sw_previous
363 - allow non-numerical key values ("C#4" for example)
364 - "key" opcode now sets pitch_keycenter too
365 - fixed error when unloading instrument with same sample used by
366 multiple regions
367 - added some opcode aliases, like loopmode for loop_mode, to be
368 more compatible
369 - added support for trigger=release and rt_decay
370 - added support for off_mode=normal
371 - added support for random, seq_position, seq_length and volume
372 - added v1 LFO opcodes to parser (no support in engine yet)
373 - added support for amp_veltrack and amp_velcurve_N
374 - fine-tuned the default velocity curve
375 - added support for transpose
376 - fixed crash when using sw_down/up
377 - improved logic for sw_lokey/hikey/up/down/last
378 - added more v1 aliases to parser
379 - reduced memory usage for sfz data
380 - RT-safeness: avoid malloc in audio thread
381 - fixed a bug that could cause voice stealing to fail
382 - optimized sample lookup
383 - improved support for exclusive groups (group, off_by and
384 off_mode)
385 - added support for controller triggered regions (on_locc/on_hicc)
386 - added support for loop_mode=one_shot
387 - fixed playback of 16 bit wav files on big endian CPUs
388 - added support for Ogg Vorbis sample files
389 - use loop markers from sample file if loop_start and loop_end are
390 not set in sfz file
391 - implemeted filters. Filter types: lowpass, bandpass, bandreject
392 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
393 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
394 cutoff_cc, cutoff_chanaft.
395 - bugfix: zero ampeg_sustain didn't work

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

758 crashes and noise on such transitions).
759 - ignore missing LADSPA paths without ignoring valid LADSPA paths
760 (fixes #208)
761 - Fixed bug in LSCP grammar definition which caused a statement like
762 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
763 practically irrelevant, however it caused problems with the new LSCP
764 shell's auto completion feature).
765 - Fixed MIDI program change messages being ignored if quickly executed
766 after each other (fixes #231).
767
768 Version 1.0.0 (31 July 2009)
769

784 directory above)
785 - configure script fix: removed unconditional use of SSE
786 - fixed building with sqlite installed in a non-standard directory
787 - when cross-compiling, don't try to create instruments.db
788 - fix for new mingw-w64 version, which has usleep
789
790 * general changes:
791 - bugfix: on some POSIX systems instrument editor plugins refused to
792 load as we used a non-portable Linux specific struct field
793 (fixes bug #70, patch by Ronald Baljeu)
794 - fixed endless loop which occured when loading an instrument editor
795 plugin DLL on Windows systems failed
796 - fixed memory leaks that occurred when liblinuxsampler was unloaded
797 - optimized the SynchronizedConfig class so it doesn't wait
798 unnecessarily long after an update

800 events (e.g. to highlight the pressed keys on the virtual keyboard
801 of gigedit)
802 - added support for triggering notes by instrument editors (see above)
803 - be verbose on DLL load errors (on Linux)
804 - fixed di-harmonic triangle LFO implementation (this LFO implementation
805 is only used by very few systems, most pick the int math
806 implementation, which is usually faster)
807 - fixes for audio drivers with varying buffer sizes
808 - experimental support for running LinuxSampler as a DSSI, LV2 and
809 VST plugin
810 - notification events for stream/voice count statistics are now sent
811 only when there are actual changes

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

835 max. 100 audio channels) for most audio drivers
836 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
837 opposed to the LSCP specs
838 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
839 reflected the wrong value
840 - fixed a memory management bug in ASIO driver
841 - Makefile fix: JACK_CFLAGS wasn't used
842 - JACK: use jack_client_open instead of the deprecated

854 energyXT)
855 - VST: changed number of output channels from one stereo to 16
856 stereo
857 - added channel routing, fxsends and midi maps to the settings
858 stored in the plugin state
859 - performance optimization of AudioChannel::MixTo() and
860 AudioChannel::CopyTo() methods using GCC vector exensions
861 (if available)
862 - ASIO fixes: avoid initializing the device twice, avoid throwing
863 exception when getting parameters from a disconnected device
864
865 * MIDI driver:
866 - added JACK MIDI driver
867 - dispatch bank select as ordinary CC as well, the user might seriously
868 want to (mis)use it for some purpose ("fixed" in all current MIDI
869 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
870 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
871 CoreMidi or AU
872 - fixed mingw-w64 compilation error in MME driver
873 - made program change handling in MIDI thread real-time safe by
874 moving the logic to a non-RT thread
875 - fixed minor memory leak in ALSA driver
876
877 * instruments database:
878 - avoid time consuming samples scanning when adding instruments
879 to the instruments database
880 - added support for handling lost files in the instruments database
881 - Implemented option for adding instruments in separate directories
882 in the instruments database
883 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
884 - work-around for missing fnmatch function on Windows to make
885 instrument database compilable
886 - added instrument database support on Windows
887 works with both standalone mode and VST plugin.
888 the instruments DB file is located in
889 %USERPROFILE%\.linuxsampler\instruments.db which allows different
890 databases for each windows user
891 if no DB is present it automatically creates the .linuxsampler subdir
892 and then creates an empty DB
893 - fixed recursive import, which was broken on Windows
894
895 * Gigasampler format engine:
896 - fixed a memory leak that could happen when a channel was deleted
897 while notes were playing
898 - made it possible to load an instrument even if the audio thread
899 isn't running
900 - added partial support for the "Controller Triggered" MIDI rule,
901 enough for piano gigs with pedal noise samples
902 - minor fix: only mark FX sends as being modified if really the
903 respective FX send MIDI controller was used
904 - added support for GM global device volume SysEx message
905 (can be selected at compile time to either apply globally to the
906 whole sampler [default] or only to the sampler channels that are
907 connected to the respective MIDI input port the SysEx message arrived
908 on)
909 - bugfix: notes triggered at position 0 in the audio buffer were
910 sometimes wrongly killed in the same buffer, causing no sound to
911 be played
912 - added support for chromatic / drumkit mode Roland GS Sysex message
913 which is usally used to switch a part between chromatic sounds and
914 drumkit sounds (as opposed to their common default setting of MIDI
915 part 10 being a drumkit part and all other ones chromatic parts), in
916 LS however one can switch between the first 16 MIDI instrument maps
917 defined for the sampler
918 - made it possible to create multiple sample channels even if the
919 audio thread isn't running
920 - fixed crash when removing channel with active voices (#116)
921 - bugfix: on sample reference changes (instrument editor), only
922 un-cache the respective sample if it's really not used by any
923 sampler engine anymore
924 - re-cache samples in case they were changed by an instrument editor,
925 e.g. when a sample was added while playing (#82)
926 - fixed hanging notes which occured when note-off event had the exact
927 same time stamp as the voice's note-on event and occured both in the
928 same audio fragment cycle (fixes bug #112)
929 - added support for the "fine tune" and "pitch bend range"
930 instrument-level gig parameters
931 - fixed minor artifacts in pitch bend handling
932 - added support for GS Reset SysEx message
933 - allow gig files to use unlimited downward pitch shifting
934 - added a limit check for upward pitch shifting
935 - bugfix: sometimes, when playing a note twice fast, the second
936 note was silent
937 - fixed crash happening when a pitch bend event arrived at the
938 same time a new instrument was loading
939
940 * LSCP server:
941 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
942 react on MIDI data arriving on certain sampler channels (so far only
943 Note-On and Note-Off events are sent via this LSCP event)
944 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
945 react on MIDI data arriving on certain MIDI input devices (so far only
946 Note-On and Note-Off events are sent via this LSCP event)
947 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
948 SET DB_INSTRUMENT FILE_PATH
949 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
950 frontends to send MIDI messages to specific sampler channel
951 - added two additional fields to GET FILE INSTRUMENT INFO command -
952 KEY_BINDINGS and KEYSWITCH_BINDINGS
953 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
954 was incorrect
955 - Optimized the retrieval of the MIDI instrument mappings
956 - added new LSCP command "SET VOICES" to globally alter the maximum
957 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
958 be triggered respectively
959 - added new LSCP command "SET STREAMS" to globally alter the maximum
960 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
961 which will be triggered respectively
962 - bugfix: retry if "select" returns EINTR (this fixes a crash when
963 a gigedit file dialog is opened)
964 - close all connections when LSCPServer is deleted
965 - hard close of all sockets on exit
966 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
967 driver
968
969 * Bug fixes:
970 - fixed a crash which occurs when removing a sampler channel waiting
971 to start instrument loading after another channel
972 - fixed a crash which occurs when removing a sampler channel with
973 instrument loading in progress (bug #113)
974 - fixed termination caused by uncaught exception when adding MIDI
975 instrument with PERSISTENT load mode
976 - fixed possible iterator invalidations when resetting the sampler
977 - fixed memory leaks when issuing the following LSCP commands:
978 GET AUDIO_OUTPUT_DRIVER INFO
979 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
980 GET MIDI_INPUT_DRIVER INFO
981 GET MIDI_INPUT_DRIVER_PARAMETER INFO
982 - fixed possible compilation error when sqlite is not present
983 - fixed orphaned pointers when setting maximum voices limit (bug #118)
984 - fixed crash when changing the audio output device of a sampler
985 channel with loaded instrument and start playing notes
986 - fixed endless loop in Engine::SuspendAll() (bug #120)
987 - fixed a low-level atomic load function that was broken on 64-bit
988 PowerPC, which probably could cause crashes on that platform
989 - fixed a memory management error which could cause a crash when a
990 plugin was unloaded
991 - bugfix: two private structs had the same name, which could cause
992 problems if the linker chose the wrong constructor
993 - fixed low-level ConditionServer usage bug that caused lockups on
994 Windows
995
996
997 Version 0.5.1 (6 December 2007)
998
999 * packaging changes:
1000 - added autoconf checks for pthread library
1001 - added autoconf check for pthread bug found on certain NPTL-enabled
1002 glibc versions (see Gentoo bug report #194076)
1003 - added autoconf checks for MS Windows
1004
1005 * general changes:
1006 - bugfix: the thread used by an editor plugin didn't die when the
1007 editor closed
1008 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1009 out all the space. operator--() did not apply size_mask after
1010 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1011 order to avoid problems with the _NonVolatileReader functions.
1012 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1013 GetWriteSpace(). Since this function is currently only used in
1014 the stream's qsort() compare function, it didn't trigger any
1015 bugs.
1016 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1017 24bit mode too. Faster method to read 24bit words on little
1018 endian machines (x86): replaced 3 byte reads + shifts with a 1
1019 unaligned 32bit read and shift
1020 - experimental support for MS Windows (MIDI input via MME, AUDIO
1021 output via ASIO)
1022 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1023 - support for monitoring the total number of active disk streams
1024 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1025 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1026
1027 * AUDIO driver:
1028 - added Windows ASIO low latency audio driver
1029
1030 * MIDI driver:
1031 - added MME Windows MIDI driver
1032
1033 * LSCP server:
1034 - added support for Windows style path / filenames, however with
1035 forward slash path separators instead of backslash
1036 (i.e. "C:/foo/bar.gig")
1037 - allow naughty liblscp to send non-string device parameters within
1038 apostrophes as well
1039 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1040 "LIST FILE INSTRUMENTS <file>" and
1041 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1042 about an arbitrary instrument file on the system where the sampler is
1043 running on
1044
1045 Version 0.5.0 (15 October 2007)
1046
1047 * packaging changes:
1048 - config.h is not going to be installed along with liblinuxsampler's
1049 API header files anymore
1050 - only the API relevant header (and source) files will be exported to
1051 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1052 - added completely new XCode project files for Mac OSX which is now
1053 capable to execute our autoconf environment, thus no need anymore
1054 to maintain the compile time configuration file (osx/version.h) for
1055 OSX manually (patch by Toshi Nagata)
1056 - fixed buggy boolean --enable-foo / --disable-foo configure script
1057 parameters
1058 - global.h now only covers global definitions that are needed for the
1059 C++ API header files, all implementation internal global definitions
1060 are now in global_private.h
1061 - atomic.h is not exposed to the C++ API anymore
1062 - no need to include config.h anymore for using LS's API header files
1063 - fixed warnings in API doc generation
1064
1065 * general changes:
1066 - replaced the old, confusing MIDI program change mechanism by a
1067 flexible MIDI instrument mapper which allows to map arbitrary
1068 (MIDI bank, MIDI program) pairs with arbitrary
1069 (engine type, instrument file, file index) triplets which will be
1070 loaded on the respective channel when such MIDI program change
1071 messages arrive, beside that, each entry allows to define a life-time
1072 strategy for the instrument, so the user can define whether the
1073 instrument should i.e. be permanently loaded (to be able to switch
1074 quickly among sounds) or i.e. loaded just on demand when the
1075 respective program change arrives (to safe RAM space), as well as a
1076 global volume factor for each entry, so the user can adjust the volume
1077 dynamic of his mapped instrument collection without having to modify
1078 the instrument files, also one can manage arbitrary amount of such
1079 MIDI instrument maps and assign each sampler channel individually
1080 a certain map, so that i.e. separation of normal instruments and
1081 drumkits is possible
1082 - new notification events for tracking changes to audio/MIDI devices,
1083 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1084 - sampler was limited to load max. 200 instruments in the background
1085 due to a constant size RingBuffer FIFO which is now replaced by a
1086 dynamic (unlimited) size std::list FIFO
1087 - added FX sends, these allow to route audio signals to arbitrary audio
1088 output channels for being processed by external effect processors
1089 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1090 controllers
1091 - global (sampler wide) volume can now be controlled at runtime
1092 - Implemented new, improved notification system
1093 - fixed compilation errors regarding OSX
1094 (patch by Toshi Nagata)
1095 - implemented instruments database
1096 - added support for escape sequences to the instruments database
1097 - added highly experimental support for on-the-fly instrument editing
1098 within the sampler's process (by using instrument editor plugins),
1099 you'll notice the new "Registered instrument editors:" message on
1100 startup, added a new LSCP command:
1101 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1102 to spawn a matching instrument editor for the instrument on the
1103 given sampler channel, the plugin path can be overridden at compile
1104 time with ./configure --enable-plugin-dir=/some/dir
1105 - added experimental code for synchronizing instrument editors hosted
1106 in the sampler's process to safely edit instruments while playing
1107 without a crash (hopefully) by either suspending single regions
1108 wherever possible or if unavoidable whole engine(s)
1109 - fixed several issues in fundamental "Thread" class: set scheduling
1110 policy and priority on thread level, set a minimum stack size for
1111 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1112 threads simply inherited properties of starting thread instead of
1113 setting their own policy and priority
1114 - minor fix in our automatic stack trace mechanism on crashes, the
1115 main process did not wait for the stack trace process to finish
1116 its output
1117 - fixed some minor memory leaks
1118 - reenabled assembly features support, at the moment only for
1119 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1120 - minor assembly fix in x86 features detection (don't use the PIC
1121 register, to avoid relocations in the text segment at runtime)
1122 - POSIX callback functions of Thread.h are hidden
1123
1124 * MIDI driver:
1125 - dispatch bank select (MSB and LSB) messages
1126
1127 * audio driver:
1128 - the ALSA audio output driver parameters now reflect the correct
1129 parameter value ranges for the respective selected sound card
1130 (patch by Till Wimmer, a bit fixed and extended)
1131
1132 * Gigasampler format engine:
1133 - if a filter is used and EG2 finishes before EG1, let the voice
1134 die when EG2 has finished (this fixes a problem with clicks and
1135 voice starvation for some gigs)
1136 - playback is no longer disabled during instrument loading
1137 - all notes playing on a channel that changes its instrument keep
1138 playing with the old instrument until they get a note off
1139 command
1140 - EG fix: a release value of zero could cause noises or crash
1141 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1142 - EG fine tuning: when attack is zero the EG starts at a level
1143 above max sustain level, which means that there is a decay phase
1144 even if sustain is 100%
1145 - more EG fixes: the level could sometimes go below zero and cause
1146 noises or crashes
1147 - minor fix of EGDecay (patch by Toshi Nagata)
1148 - fixed compiler error when --enable-override-filter-type was
1149 supplied to the configure script (fixes #46)
1150 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1151 instead of a fix value
1152 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1153 127 (solo mode) only kill voices if the respective mode really
1154 changed
1155
1156 * LSCP server:
1157 - fixed compile time error for old Bison versions
1158 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1159 - parser now supports extended ASCII character set
1160 (up to ASCII code 255, i.e. includes now umlauts and accents)
1161 - filename arguments in LSCP commands now allow to use escape
1162 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1163 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1164 code value like \xf2) (fixes bug #24)
1165 - the following LSCP commands now also support escape sequences for at
1166 least one of their text-based parameters (i.e. name, description):
1167 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1168 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1169 "SET DB_INSTRUMENT_DIRECTORY NAME",
1170 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1171 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1172 "FIND DB_INSTRUMENT_DIRECTORIES"
1173 - returns verbose syntax errors (line and column where syntax error
1174 occured, the unexpected character and the actually expected, possible
1175 character(s), the latter only if less than 5 possibilities)
1176 - made sure that LSCP syntax is not affected by gigedit locale
1177 settings
1178 - bugfix regarding strings parameter lists: all comma separated lists
1179 of strings were treated as being one string containing commas
1180 (fixes #57)
1181
1182 * Bug fixes:
1183 - fixed crash occurring on certain LSCP scripts (Bug 39)
1184 - another thread safety fix for lscp "load engine" and "set
1185 channel audio output device"
1186 - fixed a crash which occurs when reassigning the same engine
1187 on a sampler channel with connected MIDI device
1188 - fixed a crash which occurs when changing the number of ports of a MIDI
1189 device connected to a sampler channel to number less then or equal
1190 to the index of the port to which the sampler channel is connected.
1191 - The previous bindings were not been disconnected when altering
1192 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1193 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1194 - The active stream/voice count statistic was incorrect.
1195 - notification events were not been sent for some sampler
1196 channel changes
1197 - added default min and max values to restrict the number of allowed
1198 audio output channels and MIDI input ports
1199 - the connection to the PCM interface is now closed when destroying
1200 an audio output device
1201 - files with slash in their path or filename could not be loaded
1202
1203 * test cases:
1204 - updated and fixed (haven't been touched in a while)
1205
1206 Version 0.4.0 (24 November 2006)
1207
1208 * packaging changes:
1209 - changed deprecated copyright attribute to license; added ldconfig
1210 to post-(un)install steps; added devel package for liblinuxsampler;
1211 to linuxsampler.spec (RPM)
1212 - install necessary development header files for allowing 3rd party
1213 applications to link against liblinuxsampler
1214 - liblinuxsampler's API documentation can be generated with 'make docs'
1215 (Doxygen required)
1216 - added benchmark to automatically detect the best triangle LFO
1217 implementation (currently either an integer math solution or a
1218 di-harmonic approximation), automatic detection can be overriden
1219 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1220 configure script argument though (mandatory for cross-compilation)
1221 - do not automatically pick optimized gcc flags if the user already
1222 provided some on his own (as CXXFLAGS)
1223 - added compile time option to disable processing of All-Notes-Off MIDI
1224 messages
1225 - added compile time options to allow disabling the various audio and
1226 MIDI drivers
1227 - fixed automatic GCC CPU switch detection on PPC
1228 (patch by Ebrahim Mayat)
1229
1230 * Gigasampler format engine:
1231 - extensive synthesis optimization
1232 (reimplementation of EGs and LFO(s), removed synthesis parameter
1233 prerendering and the synthesis parameter matrix in general, splitting
1234 each audio fragment into subfragments now where each subfragment uses
1235 constant pitch and filter coefficients. The volume coefficient is
1236 linearly interpolated inside a subfragment, unless
1237 --disable-interpolate-volume is set.)
1238 - fine tuning of the EG modulation parameters
1239 - improved filter cutoff calculation by adding support for the
1240 following gig parameters: Cutoff freq (used when no cutoff
1241 controller is defined), Control invert, Minimum cutoff, Velocity
1242 curve and Velocity range. The keyboard tracking now scales
1243 cutoff frequency instead of resonance.
1244 - added support for gig parameter Resonance.
1245 - fixed bug in sysex handling (patch by Juan Linietsky)
1246 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1247 which can be overridden with --enable-global-attenuation
1248 - EG fixes: made the length of "attack hold" stage more
1249 accurate. Release stage can now start before attack stage
1250 ends. Cancel release didn't work when sustain was zero. Attack
1251 time now has a minimal value to prevent clicks.
1252 - fixed pitch changes larger than one octave
1253 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1254 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1255 all modes can be altered via standard GM messages, that is CC5 for
1256 altering portamento time, CC65 for enabling / disabling portamento
1257 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1258 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1259 parameter) and crossfade
1260 - added support for the "attenuation controller threshold" gig
1261 parameter
1262 - added smoothing of volume changes caused by control change
1263 messages
1264 - sample loop parameters are now taken from the DimensionRegion
1265 instead of the wave chunk
1266 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1267 not equal to a power of two
1268 - reimplementation of the filter algorithm. The new filter is more
1269 accurate and supports all gig filter types, including bandreject
1270 and lowpass turbo.
1271 - real support for 24 bit samples - samples are not truncated to
1272 16 bits anymore
1273 - support for aftertouch (channel pressure, not polyphonic
1274 aftertouch)
1275 - LFO1 behaviour fixed (dampening from max volume instead of
1276 amplifying from 0)
1277
1278 * LSCP server:
1279 - fixed application exit on broken pipe error (fixes bug #20)
1280 - fixed the notification messages delay due to lack of
1281 network activity (fixes bug #26)
1282 - fixed parser bug which occured on space(s) within device parameters
1283 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1284
1285 * audio driver:
1286 - added aRts audio output driver (by no means RT safe)
1287
1288 * MIDI driver:
1289 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1290 messages several times instead of once
1291 - API extension for MIDI drivers which already supply exact time stamps
1292 for events (i.e. for offline rendering based MIDI drivers)
1293 - added checks for bad MIDI data
1294
1295 * linuxsampler application:
1296 - show available sampler engine types on startup
1297
1298 * general changes:
1299 - support for muting sampler channels and solo mode of the same, two new
1300 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1301 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1302 introduced for this, the behavior is the same like on a mixer console
1303 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1304 --enable-process-muted-channels which can be used to enable the
1305 processing of muted channels.
1306 - support for sostenuto pedal
1307 - support for monitoring the total number of active voices
1308 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1309 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1310 - fixed some memory management errors
1311 - fixed some concurrency problems that could lead to crashes when
1312 LSCP commands were executed
1313 - fixed crash when instrument loading failed previously on the same
1314 sampler channel (fixes bug #36)
1315
1316 Version 0.3.3 (15 July 2005)
1317
1318 * packaging changes:
1319 - fixed compilation with gcc 4.0
1320
1321 * Gigasampler format engine:
1322 - LFO preprocessing was performed even though the respective LFO was
1323 disabled by the instrument patch (minor efficiency fix)
1324 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1325 for volume ramp downs in the same fragment (needed for current voice
1326 stealing implementation) then simply inform the user with a warning
1327 about possible click sounds and reduce the volume ramp down
1328 appropriately instead of cancelling the audio device connection
1329
1330 Version 0.3.2 (24 June 2005)
1331
1332 * packaging changes:
1333 - updated autotools build files to compile on OS X
1334 (conditional compilation of CoreMIDI and MidiShare drivers)
1335 - hand-crafted assembly optimization code can be disabled with
1336 './configure --disable-asm' (definitely not recommended)
1337 - fixed 'make dist' rule to include all necessary files
1338 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1339 (due to 'dist-bzip2' automake option)
1340
1341 * Gigasampler format engine:
1342 - support for the gig parameters for "release velocity response" curves
1343 - fine tuning of the EGADSR envelope
1344 - volume of release triggered samples now depends on note-on velocity,
1345 note length and gig parameter "release trigger decay" instead of
1346 note-off velocity.
1347 - revised voice stealing
1348 (fixes crash and endless loop caused by voice stealing)
1349 - don't reset scale tuning on instrument or audio output device change
1350 - handle key group conflicts right at the beginning of each fragment
1351 instead of when the respective voice is actually launched
1352 (fixes undefined behavior if stolen voices belonged to a key group -
1353 this case was followed by a "killed voice survived" error message)
1354 - fixed minor issue with null/silence samples
1355 (those stole voices even though they don't need a voice at all which
1356 resulted in "voice stealing didn't work out" messages)
1357 - don't reset volume, pan, pitch and MIDI controller values on
1358 instrument or audio output device change
1359
1360 * LSCP server:
1361 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1362 - fixed LSCP event "CHANNEL_INFO" notification
1363 (e.g. did not notify on volume changes or MIDI program change events)
1364
1365 * linuxsampler application:
1366 - added command line parameters --lscp-addr and --lscp-port to override
1367 default IP address and port of LSCP server
1368
1369 Version 0.3.1 (24 May 2005)
1370
1371 * initial release
