File size: 73396 byte(s)
* NKSP: Implemented built-in script function "change_play_pos()".
* Bumped version (2.0.0.svn57).

1 Version SVN trunk (?)
2
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
5 - Removed code duplication in SFZ file loading code.
6 - Added support for sfz extension opcode 'script' which may be used to
7 load real-time instrument script file (NKSP script language).
8 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9 - Fixed unintended volume fade-in of voices under certain conditions.
10
11 * Gigasampler/GigaStudio format engine:
12 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13 cutoff settings.
14
15 * general changes:
16 - fixed printf type errors (mostly in debug messages)
17 - use unique_ptr instead of auto_ptr when building with C++11
18 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19 allowing to sort data efficiently in real-time safe manner.
20 - RTList class: added methods for moving/inserting elements to arbitrary
21 position within a list.
22 - RTList class: added method fromPtr() for creating an Iterator object from
23 a raw element pointer.
24 - Attempt to partly fix resetting engine channels vs. resetting engine, an
25 overall cleanup of the Reset*(), ConnectAudioDevice(),
26 DisconnectAudioDevice() API methods would still be desirable though,
27 because the current situation is still inconsistent and error prone.
28 - Active voices are now internally grouped to "Note" objects, instead of
29 being directly assigned to a keyboard key. This allows more fine graded
30 processing of voices, which is i.e. required for certain instrument
31 script features.
32 - Fix: Release trigger voices were not spawned on sustain pedal up
33 (CC #64) events.
34 - Fix: Release trigger voices can now also distinguish correctly between
35 note-off and sustain pedal up events.
36 - All engines: Increased ramp speed of volume smoother and pan smoother
37 (while slow rate of crossfade smoother is preserved) to allow quick
38 volume and pan changes by instrument scripts for instance.
39 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40 properly and thus were ignored for certain uses.
41 - Added new C++ API method
42 VirtualMidiDevice::SendChannelPressureToSampler().
43 - windows, 32-bit: fixed potential crashes by making sure the stack in
44 sub threads is 16-byte aligned
45 - fixed numerous compiler warnings
46 - Fixed invalid (note-on) event ID being assigned to new Note objects.
47
48 * packaging changes:
49 - removed unnecessary dependency to libuuid
50 (originated by libgig's usage of it)
51 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
52 auto detect whether it (sh/c)ould output its messages in color.
53
54 * Real-time instrument scripts:
55 - Implemented scheduler for delayed MIDI events and for suspended scripts.
56 - Built-in script function "wait()": implemented support for function's
57 "duration-us" argument, thus scripts using this function are now
58 correctly resumed after the requested amount of microseconds.
59 - Built-in script function "play_note()": implemented support for
60 function's "duration-us" argument, thus notes triggered with this
61 argument are now correctly released after the requested amount of
62 microseconds.
63 - Fix: script events were not cleared when engine channel was reset,
64 potentially causing undefined behavior.
65 - Fixed crash which happened when trying to reference an undeclared
66 variable.
67 - Built-in script function "play_note()": Added support for passing
68 special value -1 for "duration-us" argument, which will cause the
69 triggered note to be released once the original note was released.
70 - Instrument script classes now exported with the liblinuxsampler C++ API.
71 - Added new API method ScriptVM::syntaxHighlighting() which provides
72 a convenient syntax highlighting backend for external instrument
73 script editor applications.
74 - Added new C++ API class "ScriptVMFactory".
75 - Extended parser issues to provide not only first line and first
76 column, but also last line and last column of issue (thus marking
77 the precise span of the issue within the source code).
78 - Reload script automatically after being modified by an instrument
79 editor.
80 - NKSP language grammar correction: allow empty event handler bodies
81 like "on note end on".
82 - Implemented built-in script function "change_vol()".
83 - Implemented built-in script function "change_tune()".
84 - Implemented built-in script function "change_pan()".
85 - Implemented built-in script function "change_cutoff()".
86 - Implemented built-in script function "change_reso()".
87 - Implemented built-in script function "event_status()".
88 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
89 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
90 "event_status()" function.
91 - NKSP language: Added support for bitwise operators ".or.", ".and."
92 and ".not.".
93 - NKSP language scanner: Fixed IDs matching to require at least one
94 character (i.e. when matching function names or variable names).
95 - NKSP language scanner: disabled unusued rules.
96 - Fixed behavior of play_note() and note_off() functions which must
97 be distinguished engine internally from "real" MIDI note on/off
98 events in order to avoid misbehaviors like hanging notes.
99 - Implemented built-in script variable "$KSP_TIMER".
100 - Implemented built-in script variable "$NKSP_REAL_TIMER".
101 - Implemented built-in script variable "$NKSP_PERF_TIMER".
102 - Implemented built-in script variable "$ENGINE_UPTIME".
103 - Implemented built-in script function "inc()".
104 - Implemented built-in script function "dec()".
105 - NKSP language fix: division expressions were evaluated too often.
106 - NKSP language fix: string concatenation operator was right
107 associative instead of left (to right).
108 - NKSP language correction: allow empty statements in entire language
109 (i.e. "if end if").
110 - Implemented built-in script function "stop_wait()".
111 - Implemented built-in script variable "$NI_CALLBACK_ID".
112 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
113 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
114 - Added support for read-only built-in variables (respectively
115 handled by the script parser).
116 - Added built-in script constant "$NI_CB_TYPE_INIT".
117 - Added built-in script constant "$NI_CB_TYPE_NOTE".
118 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
119 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
120 - NKSP Language: Added support for user defined script functions.
121 - Implemented built-in script function "change_attack()".
122 - Implemented built-in script function "change_decay()".
123 - Implemented built-in script function "change_release()".
124 - Fixed all change_*() built-in script functions to apply their
125 synthesis parameter changes immediately in case the respective note
126 was triggered at the same time, instead of scheduling the parameter
127 change, especially because it would cause some parameter types's
128 changes either to be ramped (i.e. change_vol()) or other types even
129 to have not effect at all (i.e. change_attack()).
130 - Implemented built-in script function "sh_left()".
131 - Implemented built-in script function "sh_right()".
132 - Implemented built-in script function "min()".
133 - Implemented built-in script function "max()".
134 - NKSP Fix: "init" event handler was not always executed when a script
135 was loaded.
136 - NKSP built-in wait() script function: abort script execution if
137 a negative or zero wait time was passed as argument (since this is
138 a common indication of a bug either of the script or even of the
139 engine, which could lead to RT instability or even worse).
140 - ScriptVM: Implemented automatic suspension of RT safety
141 threatening scripts.
142 - Provide more user friendly error messages on syntax errors.
143 - Fixed NKSP parser warning "Not a statement" when assigning an
144 initializer list to an array variable.
145 - Implemented built-in script array variable "%ALL_EVENTS".
146 - Implemented built-in script function "in_range()".
147 - Implemented built-in script function "change_amp_lfo_depth()".
148 - Implemented built-in script function "change_amp_lfo_freq()".
149 - Implemented built-in script function "change_pitch_lfo_depth()".
150 - Implemented built-in script function "change_pitch_lfo_freq()".
151 - Implemented built-in script function "change_vol_time()".
152 - Implemented built-in script function "change_tune_time()".
153 - Implemented built-in script function "fade_in()".
154 - Implemented built-in script function "fade_out()".
155 - Fixed acceptance of wrong data type of parameters passed to built-in
156 script functions "change_vol()", "change_tune()", "change_pan()",
157 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 - Added built-in script function "get_event_par()" and implemented some
161 of its possible parameter selections.
162 - Added built-in script function "set_event_par()" and implemented some
163 of its possible parameter selections.
164 - Fixed a bunch of scheduler time related bugs.
165 - Fixed polyphonic variables not being reset to zero after usage.
166 - Built-in "ignore_event()" function: argument is now optional, like with
167 built-in function "ignore_controller()".
168 - Implemented built-in script function "change_velo()".
169 - Implemented built-in script function "change_note()".
170 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
171 intuitive behavior if used in combination with "change_vol_time()" or
172 "change_tune_time()" respectively: now tuning/volume changes are only
173 assigned (without delay) immediately to a new note if the respective
174 timing function has not been called before, otherwise the volume/tuning
175 changes are automatically faded (before, only the event's time stamp was
176 relevant).
177 - Implemented built-in script function "array_equal()".
178 - Implemented built-in script function "search()".
179 - Implemented built-in script function "sort()".
180 - NKSP Fix: Never suspend "init" event handlers.
181 - Implemented built-in script function "same_region()" (currently only
182 available for gig format engine).
183 - Added built-in script constant "$NKSP_LINEAR".
184 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
185 - Implemented built-in script function "change_vol_curve()".
186 - Implemented built-in script function "change_tune_curve()".
187 - built-in "play_note()" function now supports a sample playback start
188 offset with argument 3, where special value -1 means to use the regular
189 sample offset as defined by the instrument file.
190 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
191 - Built-in variable $EVENT_NOTE is now a read-only variable.
192 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
193 - built-in "play_note()" function now accepts -2 for its fourth argument
194 (note duration) which means the life time of the note shall be sticked
195 to the requested note number of argument 1.
196 - Fix: built-in "play_note()" function now returns 0 as result value if
197 -1 was passed for its fourth argument (note duration) and the respective
198 parent note is already gone.
199 - Implemented built-in script function "change_play_pos()".
200
201 * Instruments DB:
202 - Fixed memory access bug of general DB access code which lead to
203 undefined behavior.
204 - Cleanup of instruments DB file creation and opening code.
205 - The instrument DB path of linuxsampler's --create-instruments-db argument
206 is now optional, if it is missing, then a default location is used.
207 - Added support for scanning SFZ (.sfz) files.
208 - Added support for scanning Sound Font (.sf2) files.
209 - Fixed undefined DB transaction behavior.

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

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

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

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

774
775 * general changes:
776 - bugfix: on some POSIX systems instrument editor plugins refused to

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

786 of gigedit)
787 - added support for triggering notes by instrument editors (see above)
788 - be verbose on DLL load errors (on Linux)
789 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

822 opposed to the LSCP specs
823 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
824 reflected the wrong value
825 - fixed a memory management bug in ASIO driver
826 - Makefile fix: JACK_CFLAGS wasn't used
827 - JACK: use jack_client_open instead of the deprecated

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

855 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
856 CoreMidi or AU
857 - fixed mingw-w64 compilation error in MME driver
858 - made program change handling in MIDI thread real-time safe by
859 moving the logic to a non-RT thread

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