Mon May 29 22:19:19 2017 UTC (6 years, 10 months ago) by schoenebeck
File size: 72724 byte(s)
* NKSP: built-in "play_note()" function now supports a sample playback
  start offset with argument 3, where special value -1 means to use the
  regular sample offset as defined by the instrument file.
* Bumped version (2.0.0.svn55).

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
191 * Instruments DB:
192 - Fixed memory access bug of general DB access code which lead to
193 undefined behavior.
194 - Cleanup of instruments DB file creation and opening code.
195 - The instrument DB path of linuxsampler's --create-instruments-db argument
196 is now optional, if it is missing, then a default location is used.
197 - Added support for scanning SFZ (.sfz) files.
198 - Added support for scanning Sound Font (.sf2) files.
199 - Fixed undefined DB transaction behavior.

236 - support building with spaces in vst sdk path
237 - enabled automake 'subdir-objects' option and moved external
238 source references (vst, au, asio) from makefiles to cpp files,
239 in order to get rid of warnings from automake 1.14
240
241 * general changes:
242 - Refactoring: moved the independent code from
243 the Gigasampler format engine to base classes
244 - command line option '--profile' is currently disabled, since the
245 respective profiling code is currently broken
246 - Introduced support for optional environment variable
247 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
248 where the sampler shall look for instrument editor plugins
249 (patch by Luis Garrido, slightly modified).
250 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
251 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
252 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
253 note (in this implementation of the sampler its simply hard routed to
254 the 1st effect send of the sampler channel, no matter what the actual
255 effect type is)
256 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
257 note (in this implementation of the sampler its simply hard routed to
258 the 2nd effect send of the sampler channel, no matter what the actual
259 effect type is)
260 - implemented support for internal LADSPA effects
261 - raised limit of program change queue from 100 to 512
262 (as suggested by Alex Stone)
263 - implemented sine LFO, pulse LFO and saw LFO
264 - experimental support for per voice equalization
265 - added command line option --exec-after-init
266 - Introduced new C++ API method:
267 EngineChannel::InstrumentFileName(int index)
268 allowing to retrieve the whole list of files used for the loaded
269 instrument on an engine channel (a.k.a. part). Some GigaStudio
270 instruments for example are splitted over several files like
271 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
272 - Added new C++ API method Sampler::GetGlobalMaxVoices().
273 - Added new C++ API method Sampler::GetGlobalMaxStreams().
274 - Added new C++ API method Sampler::SetGlobalMaxVoices().
275 - Added new C++ API method Sampler::SetGlobalMaxStreams().
276 - Various "const" and "restrict" optimizations.
277 - all engines: add pan CC value to instrument pan parameter before
278 applying panning, instead of using two separate pan functions in
279 series (#182)
280 - added a lock guard class for exception safe mutex handling and
281 used it everywhere appropriate
282 - Immediately apply scale tuning changes to active voices.
283 - Exposed scale tuning to C++ API (along to the already existing standard
284 SysEx way).
285 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
286 and broken for ppc64. (Seq_cst loads and stores are actually not
287 used in LS, so the bug wasn't noticable.)
288 - lsatomic.h: added ARMv7 support
289 - Added support for multiple MIDI input ports per sampler channel (and
290 added various new C++ methods for this new feature / design change, old
291 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
292 as deprecated but are still there and should provide full behavior
293 backward compatibility).
294 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
295 unsafe and caused compilation error with clang 2.x).
296 - Bugfix: only process the latest MIDI program change event.
297 - Introducing the LSCP shell, which provides convenient control of the
298 sampler from the command line by providing LSCP aware features.
299 - VirtualMidiDevice: Added support for program change.
300 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
301 - VirtualMidiDevice: Added support for pitch bend.
302 - Aftertouch: extended API to explicitly handle channel pressure and
303 polyphonic key pressure events (so far polyphonic pressure was not
304 supported at all, and channel pressure was rerouted as CC128 but not
305 used so far).
306 - Added initial support for real-time instrument scripts. The script VM
307 code is shared by all sampler engine implemementations, however only the
308 gig file format currently provides support for storing instrument scripts
309 (as LinuxSampler extension to the original GigaStudio 4 format).
310
311 * Gigasampler format engine:
312 - implemented the "round robin keyboard" dimension
313 - fixed round robin and random dimensions for cases when number of
314 dimension zones is not a power of two
315 - made round robin use a counter for each region instead of each
316 key
317 - bugfix: pitch LFO controller "internal+aftertouch" was broken
318 - bugfix: filter keyboard tracking was broken
319 - filter performance fix (an unnecessary copy was made of the
320 filter parameters in each sub fragment)
321 - handle special case when pan parameter in gig file has max or
322 min value
323 - Exclusive Groups: don't ever stop voices of the same note,
324 doesn't sound naturally with a drumkit
325 - fixed EG1 modulation when attack or release is zero
326 - Fixed support for 'aftertouch' attenuation controller.
327 - Fixed crash that happened with velocity split sounds under certain
328 conditions (see also previous commit on libgig).
329 - fixed behaviour of filter LFO
330
331 * SFZ format engine:
332 - Initial implementation (not usable yet)
333 - added support for v2 multiple stage envelope generators
334 - added a fine-tuned v1 envelope generator instead of using the
335 one from the gig engine
336 - fixed memory leak and memory handling errors
337 - added support for trigger=first, trigger=legato and sw_previous
338 - allow non-numerical key values ("C#4" for example)
339 - "key" opcode now sets pitch_keycenter too
340 - fixed error when unloading instrument with same sample used by
341 multiple regions
342 - added some opcode aliases, like loopmode for loop_mode, to be
343 more compatible
344 - added support for trigger=release and rt_decay
345 - added support for off_mode=normal
346 - added support for random, seq_position, seq_length and volume
347 - added v1 LFO opcodes to parser (no support in engine yet)
348 - added support for amp_veltrack and amp_velcurve_N
349 - fine-tuned the default velocity curve
350 - added support for transpose
351 - fixed crash when using sw_down/up
352 - improved logic for sw_lokey/hikey/up/down/last
353 - added more v1 aliases to parser
354 - reduced memory usage for sfz data
355 - RT-safeness: avoid malloc in audio thread

361 - added support for loop_mode=one_shot
362 - fixed playback of 16 bit wav files on big endian CPUs
363 - added support for Ogg Vorbis sample files
364 - use loop markers from sample file if loop_start and loop_end are
365 not set in sfz file
366 - implemeted filters. Filter types: lowpass, bandpass, bandreject
367 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
368 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
369 cutoff_cc, cutoff_chanaft.
370 - bugfix: zero ampeg_sustain didn't work

559 the driver will automatically connect to other CoreMIDI clients' ports
560 (e.g. external MIDI devices being attached to the Mac)
561 - added support for MIDI note on velocity filter
562 - CoreMIDI: fixed memory deallocation error
563 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

705 it caused hanging threads on Windows
706 - Fixed possible crashes due to corrupted MIDI/audio device list
707 after MIDI/audio device creation failure
708 - When creating MIDI instrument map entries with "PERSISTENT" type, the
709 instruments were uselessly precached with zero samples, however it still
710 took the full preloading time and on 1st program change the respective

733 crashes and noise on such transitions).
734 - ignore missing LADSPA paths without ignoring valid LADSPA paths
735 (fixes #208)
736 - Fixed bug in LSCP grammar definition which caused a statement like
737 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
738 practically irrelevant, however it caused problems with the new LSCP
739 shell's auto completion feature).
740 - Fixed MIDI program change messages being ignored if quickly executed
741 after each other (fixes #231).
742
743 Version 1.0.0 (31 July 2009)
744
745 * packaging changes:
746 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

759 directory above)
760 - configure script fix: removed unconditional use of SSE
761 - fixed building with sqlite installed in a non-standard directory
762 - when cross-compiling, don't try to create instruments.db
763 - fix for new mingw-w64 version, which has usleep
764
765 * general changes:
766 - bugfix: on some POSIX systems instrument editor plugins refused to

768 (fixes bug #70, patch by Ronald Baljeu)
769 - fixed endless loop which occured when loading an instrument editor
770 plugin DLL on Windows systems failed
771 - fixed memory leaks that occurred when liblinuxsampler was unloaded
772 - optimized the SynchronizedConfig class so it doesn't wait
773 unnecessarily long after an update
774 - added support for notifying instrument editors on note-on / note-off
775 events (e.g. to highlight the pressed keys on the virtual keyboard
776 of gigedit)
777 - added support for triggering notes by instrument editors (see above)
778 - be verbose on DLL load errors (on Linux)
779 - fixed di-harmonic triangle LFO implementation (this LFO implementation
780 is only used by very few systems, most pick the int math
781 implementation, which is usually faster)
782 - fixes for audio drivers with varying buffer sizes
783 - experimental support for running LinuxSampler as a DSSI, LV2 and
784 VST plugin
785 - notification events for stream/voice count statistics are now sent

790 - fixed CPU feature detection on x86_64 (maybe fixes #108)
791 - automatic stacktrace mechanism is now turned off by default and can
792 be switched on by command line option "--stacktrace" (the automatic
793 stacktrace mechanism seems to be broken on most systems at the moment)
794 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
795 a pointer to the launched InstrumentEditor object
796 - added optional 3rd party user data parameter for following
797 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
798 InstrumentEditor::Launch(),
799 InstrumentManager::LaunchInstrumentEditor()
800 - theoretical fix: made SynchronizedConfig follow C++0x memory
801 model more strictly
802 - fixes for using large audio device buffers
803 - Windows: add the installation directory to the DLL search path
804 when loading an editor plugin (solves problems with VST and
805 gigedit on systems with other GTK versions installed)
806 - updated linuxsampler man page
807
808 * audio driver:
809 - removed the nonsense audio channel constraint (which was hard coded to
810 max. 100 audio channels) for most audio drivers
811 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
812 opposed to the LSCP specs
813 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
814 reflected the wrong value
815 - fixed a memory management bug in ASIO driver
816 - Makefile fix: JACK_CFLAGS wasn't used
817 - JACK: use jack_client_open instead of the deprecated
818 jack_client_new

829 energyXT)
830 - VST: changed number of output channels from one stereo to 16
831 stereo
832 - added channel routing, fxsends and midi maps to the settings
833 stored in the plugin state
834 - performance optimization of AudioChannel::MixTo() and
835 AudioChannel::CopyTo() methods using GCC vector exensions
836 (if available)
837 - ASIO fixes: avoid initializing the device twice, avoid throwing
838 exception when getting parameters from a disconnected device
839
840 * MIDI driver:
841 - added JACK MIDI driver
842 - dispatch bank select as ordinary CC as well, the user might seriously
843 want to (mis)use it for some purpose ("fixed" in all current MIDI
844 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
845 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
846 CoreMidi or AU
847 - fixed mingw-w64 compilation error in MME driver
848 - made program change handling in MIDI thread real-time safe by
849 moving the logic to a non-RT thread

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