File size: 74876 byte(s)
* Added built-in script function "callback_status()".
* Added built-in constant $CALLBACK_STATUS_TERMINATED.
* Added built-in constant $CALLBACK_STATUS_QUEUE.
* Added built-in constant $CALLBACK_STATUS_RUNNING.
* Bumped version (2.0.0.svn66).

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

124 - Implemented built-in script function "change_attack()".
125 - Implemented built-in script function "change_decay()".
126 - Implemented built-in script function "change_release()".
127 - Fixed all change_*() built-in script functions to apply their
128 synthesis parameter changes immediately in case the respective note
129 was triggered at the same time, instead of scheduling the parameter
130 change, especially because it would cause some parameter types's
131 changes either to be ramped (i.e. change_vol()) or other types even
132 to have not effect at all (i.e. change_attack()).
133 - Implemented built-in script function "sh_left()".
134 - Implemented built-in script function "sh_right()".
135 - Implemented built-in script function "min()".
136 - Implemented built-in script function "max()".
137 - NKSP Fix: "init" event handler was not always executed when a script
138 was loaded.
139 - NKSP built-in wait() script function: abort script execution if
140 a negative or zero wait time was passed as argument (since this is
141 a common indication of a bug either of the script or even of the
142 engine, which could lead to RT instability or even worse).
143 - ScriptVM: Implemented automatic suspension of RT safety
144 threatening scripts.
145 - Provide more user friendly error messages on syntax errors.
146 - Fixed NKSP parser warning "Not a statement" when assigning an
147 initializer list to an array variable.
148 - Implemented built-in script array variable "%ALL_EVENTS".
149 - Implemented built-in script function "in_range()".
150 - Implemented built-in script function "change_amp_lfo_depth()".
151 - Implemented built-in script function "change_amp_lfo_freq()".
152 - Implemented built-in script function "change_pitch_lfo_depth()".
153 - Implemented built-in script function "change_pitch_lfo_freq()".
154 - Implemented built-in script function "change_vol_time()".
155 - Implemented built-in script function "change_tune_time()".
156 - Implemented built-in script function "fade_in()".
157 - Implemented built-in script function "fade_out()".
158 - Fixed acceptance of wrong data type of parameters passed to built-in
159 script functions "change_vol()", "change_tune()", "change_pan()",
160 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
161 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
162 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
163 - Added built-in script function "get_event_par()" and implemented some
164 of its possible parameter selections.
165 - Added built-in script function "set_event_par()" and implemented some
166 of its possible parameter selections.
167 - Fixed a bunch of scheduler time related bugs.
168 - Fixed polyphonic variables not being reset to zero after usage.
169 - Built-in "ignore_event()" function: argument is now optional, like with
170 built-in function "ignore_controller()".
171 - Implemented built-in script function "change_velo()".
172 - Implemented built-in script function "change_note()".
173 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
174 intuitive behavior if used in combination with "change_vol_time()" or
175 "change_tune_time()" respectively: now tuning/volume changes are only
176 assigned (without delay) immediately to a new note if the respective
177 timing function has not been called before, otherwise the volume/tuning
178 changes are automatically faded (before, only the event's time stamp was
179 relevant).
180 - Implemented built-in script function "array_equal()".
181 - Implemented built-in script function "search()".
182 - Implemented built-in script function "sort()".
183 - NKSP Fix: Never suspend "init" event handlers.
184 - Implemented built-in script function "same_region()" (currently only
185 available for gig format engine).
186 - Added built-in script constant "$NKSP_LINEAR".
187 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
188 - Implemented built-in script function "change_vol_curve()".
189 - Implemented built-in script function "change_tune_curve()".
190 - built-in "play_note()" function now supports a sample playback start
191 offset with argument 3, where special value -1 means to use the regular
192 sample offset as defined by the instrument file.
193 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
194 - Built-in variable $EVENT_NOTE is now a read-only variable.
195 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
196 - built-in "play_note()" function now accepts -2 for its fourth argument
197 (note duration) which means the life time of the note shall be sticked
198 to the requested note number of argument 1.
199 - Fix: built-in "play_note()" function now returns 0 as result value if
200 -1 was passed for its fourth argument (note duration) and the respective
201 parent note is already gone.
202 - Implemented built-in script function "change_play_pos()".
203 - NKSP language: Added support for user declared const array variables.
204 - NKSP language: Raise parser warning if array variable is accessed with
205 an index that exceeds the array's size.
206 - NKSP language fix: Unknown characters were not handled correctly.
207 - NKSP language: Added support for "synchronized .. end synchronized"
208 code blocks.
209 - Implemented built-in script function "abort()" which allows to abort

220 - Added built-in script function "callback_status()".
221 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
222 - Added built-in constant $CALLBACK_STATUS_QUEUE.
223 - Added built-in constant $CALLBACK_STATUS_RUNNING.
224
225 * Instruments DB:
226 - Fixed memory access bug of general DB access code which lead to
227 undefined behavior.
228 - Cleanup of instruments DB file creation and opening code.
229 - The instrument DB path of linuxsampler's --create-instruments-db argument
230 is now optional, if it is missing, then a default location is used.

273 in order to get rid of warnings from automake 1.14
274
275 * general changes:
276 - Refactoring: moved the independent code from
277 the Gigasampler format engine to base classes
278 - command line option '--profile' is currently disabled, since the
279 respective profiling code is currently broken
280 - Introduced support for optional environment variable
281 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
282 where the sampler shall look for instrument editor plugins
283 (patch by Luis Garrido, slightly modified).
284 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
285 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
286 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
287 note (in this implementation of the sampler its simply hard routed to
288 the 1st effect send of the sampler channel, no matter what the actual
289 effect type is)
290 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
291 note (in this implementation of the sampler its simply hard routed to
292 the 2nd effect send of the sampler channel, no matter what the actual
293 effect type is)
294 - implemented support for internal LADSPA effects
295 - raised limit of program change queue from 100 to 512
296 (as suggested by Alex Stone)
297 - implemented sine LFO, pulse LFO and saw LFO
298 - experimental support for per voice equalization
299 - added command line option --exec-after-init
300 - Introduced new C++ API method:
301 EngineChannel::InstrumentFileName(int index)
302 allowing to retrieve the whole list of files used for the loaded
303 instrument on an engine channel (a.k.a. part). Some GigaStudio
304 instruments for example are splitted over several files like
305 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
306 - Added new C++ API method Sampler::GetGlobalMaxVoices().
307 - Added new C++ API method Sampler::GetGlobalMaxStreams().
308 - Added new C++ API method Sampler::SetGlobalMaxVoices().
309 - Added new C++ API method Sampler::SetGlobalMaxStreams().
310 - Various "const" and "restrict" optimizations.
311 - all engines: add pan CC value to instrument pan parameter before
312 applying panning, instead of using two separate pan functions in
313 series (#182)
314 - added a lock guard class for exception safe mutex handling and
315 used it everywhere appropriate
316 - Immediately apply scale tuning changes to active voices.
317 - Exposed scale tuning to C++ API (along to the already existing standard
318 SysEx way).
319 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
320 and broken for ppc64. (Seq_cst loads and stores are actually not
321 used in LS, so the bug wasn't noticable.)
322 - lsatomic.h: added ARMv7 support
323 - Added support for multiple MIDI input ports per sampler channel (and
324 added various new C++ methods for this new feature / design change, old
325 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
326 as deprecated but are still there and should provide full behavior
327 backward compatibility).
328 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
329 unsafe and caused compilation error with clang 2.x).
330 - Bugfix: only process the latest MIDI program change event.
331 - Introducing the LSCP shell, which provides convenient control of the
332 sampler from the command line by providing LSCP aware features.
333 - VirtualMidiDevice: Added support for program change.
334 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
335 - VirtualMidiDevice: Added support for pitch bend.
336 - Aftertouch: extended API to explicitly handle channel pressure and
337 polyphonic key pressure events (so far polyphonic pressure was not
338 supported at all, and channel pressure was rerouted as CC128 but not
339 used so far).
340 - Added initial support for real-time instrument scripts. The script VM
341 code is shared by all sampler engine implemementations, however only the
342 gig file format currently provides support for storing instrument scripts
343 (as LinuxSampler extension to the original GigaStudio 4 format).
344
345 * Gigasampler format engine:
346 - implemented the "round robin keyboard" dimension
347 - fixed round robin and random dimensions for cases when number of
348 dimension zones is not a power of two
349 - made round robin use a counter for each region instead of each
350 key
351 - bugfix: pitch LFO controller "internal+aftertouch" was broken
352 - bugfix: filter keyboard tracking was broken
353 - filter performance fix (an unnecessary copy was made of the
354 filter parameters in each sub fragment)
355 - handle special case when pan parameter in gig file has max or
356 min value
357 - Exclusive Groups: don't ever stop voices of the same note,
358 doesn't sound naturally with a drumkit
359 - fixed EG1 modulation when attack or release is zero
360 - Fixed support for 'aftertouch' attenuation controller.
361 - Fixed crash that happened with velocity split sounds under certain
362 conditions (see also previous commit on libgig).
363 - fixed behaviour of filter LFO
364
365 * SFZ format engine:
366 - Initial implementation (not usable yet)
367 - added support for v2 multiple stage envelope generators
368 - added a fine-tuned v1 envelope generator instead of using the
369 one from the gig engine

371 - added support for trigger=first, trigger=legato and sw_previous
372 - allow non-numerical key values ("C#4" for example)
373 - "key" opcode now sets pitch_keycenter too
374 - fixed error when unloading instrument with same sample used by
375 multiple regions
376 - added some opcode aliases, like loopmode for loop_mode, to be
377 more compatible
378 - added support for trigger=release and rt_decay
379 - added support for off_mode=normal

395 - added support for loop_mode=one_shot
396 - fixed playback of 16 bit wav files on big endian CPUs
397 - added support for Ogg Vorbis sample files
398 - use loop markers from sample file if loop_start and loop_end are
399 not set in sfz file
400 - implemeted filters. Filter types: lowpass, bandpass, bandreject
401 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
402 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
403 cutoff_cc, cutoff_chanaft.
404 - bugfix: zero ampeg_sustain didn't work

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

767 crashes and noise on such transitions).
768 - ignore missing LADSPA paths without ignoring valid LADSPA paths
769 (fixes #208)
770 - Fixed bug in LSCP grammar definition which caused a statement like
771 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
772 practically irrelevant, however it caused problems with the new LSCP
773 shell's auto completion feature).
774 - Fixed MIDI program change messages being ignored if quickly executed
775 after each other (fixes #231).
776
777 Version 1.0.0 (31 July 2009)
778
779 * packaging changes:
780 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

792 directory of liblinuxsampler dll (look in the same directory and one
793 directory above)
794 - configure script fix: removed unconditional use of SSE
795 - fixed building with sqlite installed in a non-standard directory
796 - when cross-compiling, don't try to create instruments.db
797 - fix for new mingw-w64 version, which has usleep
798
799 * general changes:
800 - bugfix: on some POSIX systems instrument editor plugins refused to
801 load as we used a non-portable Linux specific struct field
802 (fixes bug #70, patch by Ronald Baljeu)
803 - fixed endless loop which occured when loading an instrument editor
804 plugin DLL on Windows systems failed
805 - fixed memory leaks that occurred when liblinuxsampler was unloaded
806 - optimized the SynchronizedConfig class so it doesn't wait
807 unnecessarily long after an update
808 - added support for notifying instrument editors on note-on / note-off
809 events (e.g. to highlight the pressed keys on the virtual keyboard
810 of gigedit)
811 - added support for triggering notes by instrument editors (see above)
812 - be verbose on DLL load errors (on Linux)
813 - fixed di-harmonic triangle LFO implementation (this LFO implementation
814 is only used by very few systems, most pick the int math
815 implementation, which is usually faster)
816 - fixes for audio drivers with varying buffer sizes
817 - experimental support for running LinuxSampler as a DSSI, LV2 and
818 VST plugin
819 - notification events for stream/voice count statistics are now sent
820 only when there are actual changes
821 - added memory ordering constraints to improve stability on
822 multi-core and multi-cpu systems
823 - maximum voices and disk streams can now be altered at runtime
824 - fixed CPU feature detection on x86_64 (maybe fixes #108)
825 - automatic stacktrace mechanism is now turned off by default and can
826 be switched on by command line option "--stacktrace" (the automatic
827 stacktrace mechanism seems to be broken on most systems at the moment)
828 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
829 a pointer to the launched InstrumentEditor object
830 - added optional 3rd party user data parameter for following
831 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
832 InstrumentEditor::Launch(),
833 InstrumentManager::LaunchInstrumentEditor()
834 - theoretical fix: made SynchronizedConfig follow C++0x memory
835 model more strictly
836 - fixes for using large audio device buffers
837 - Windows: add the installation directory to the DLL search path
838 when loading an editor plugin (solves problems with VST and
839 gigedit on systems with other GTK versions installed)
840 - updated linuxsampler man page
841

843 - removed the nonsense audio channel constraint (which was hard coded to
844 max. 100 audio channels) for most audio drivers
845 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
846 opposed to the LSCP specs
847 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
848 reflected the wrong value
849 - fixed a memory management bug in ASIO driver
850 - Makefile fix: JACK_CFLAGS wasn't used
851 - JACK: use jack_client_open instead of the deprecated
852 jack_client_new

858 win64)
859 - VST: added support for sample rate and buffer size changes
860 - VST: close editor (Fantasia) when the VST is removed
861 - VST: avoid opening Fantasia more than once for each VST instance
862 - VST: export main function as "main" on Linux too (fix for
863 energyXT)
864 - VST: changed number of output channels from one stereo to 16
865 stereo
866 - added channel routing, fxsends and midi maps to the settings
867 stored in the plugin state
868 - performance optimization of AudioChannel::MixTo() and
869 AudioChannel::CopyTo() methods using GCC vector exensions
870 (if available)
871 - ASIO fixes: avoid initializing the device twice, avoid throwing
872 exception when getting parameters from a disconnected device
873
874 * MIDI driver:
875 - added JACK MIDI driver
876 - dispatch bank select as ordinary CC as well, the user might seriously
877 want to (mis)use it for some purpose ("fixed" in all current MIDI
878 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
879 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
880 CoreMidi or AU
881 - fixed mingw-w64 compilation error in MME driver
882 - made program change handling in MIDI thread real-time safe by
883 moving the logic to a non-RT thread
884 - fixed minor memory leak in ALSA driver
885
886 * instruments database:
887 - avoid time consuming samples scanning when adding instruments
888 to the instruments database
889 - added support for handling lost files in the instruments database
890 - Implemented option for adding instruments in separate directories
891 in the instruments database
892 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
893 - work-around for missing fnmatch function on Windows to make
894 instrument database compilable
895 - added instrument database support on Windows
896 works with both standalone mode and VST plugin.
897 the instruments DB file is located in
898 %USERPROFILE%\.linuxsampler\instruments.db which allows different
899 databases for each windows user
900 if no DB is present it automatically creates the .linuxsampler subdir
901 and then creates an empty DB
902 - fixed recursive import, which was broken on Windows
903
904 * Gigasampler format engine:
905 - fixed a memory leak that could happen when a channel was deleted
906 while notes were playing
907 - made it possible to load an instrument even if the audio thread
908 isn't running
909 - added partial support for the "Controller Triggered" MIDI rule,
910 enough for piano gigs with pedal noise samples
911 - minor fix: only mark FX sends as being modified if really the
912 respective FX send MIDI controller was used
913 - added support for GM global device volume SysEx message
914 (can be selected at compile time to either apply globally to the
915 whole sampler [default] or only to the sampler channels that are
916 connected to the respective MIDI input port the SysEx message arrived
917 on)
918 - bugfix: notes triggered at position 0 in the audio buffer were
919 sometimes wrongly killed in the same buffer, causing no sound to
920 be played
921 - added support for chromatic / drumkit mode Roland GS Sysex message
922 which is usally used to switch a part between chromatic sounds and
923 drumkit sounds (as opposed to their common default setting of MIDI
924 part 10 being a drumkit part and all other ones chromatic parts), in
925 LS however one can switch between the first 16 MIDI instrument maps
926 defined for the sampler
927 - made it possible to create multiple sample channels even if the
928 audio thread isn't running
929 - fixed crash when removing channel with active voices (#116)
930 - bugfix: on sample reference changes (instrument editor), only
931 un-cache the respective sample if it's really not used by any
932 sampler engine anymore
933 - re-cache samples in case they were changed by an instrument editor,
934 e.g. when a sample was added while playing (#82)
935 - fixed hanging notes which occured when note-off event had the exact
936 same time stamp as the voice's note-on event and occured both in the
937 same audio fragment cycle (fixes bug #112)
938 - added support for the "fine tune" and "pitch bend range"
939 instrument-level gig parameters
940 - fixed minor artifacts in pitch bend handling
941 - added support for GS Reset SysEx message
942 - allow gig files to use unlimited downward pitch shifting
943 - added a limit check for upward pitch shifting
944 - bugfix: sometimes, when playing a note twice fast, the second
945 note was silent
946 - fixed crash happening when a pitch bend event arrived at the
947 same time a new instrument was loading
948
949 * LSCP server:
950 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
951 react on MIDI data arriving on certain sampler channels (so far only
952 Note-On and Note-Off events are sent via this LSCP event)
953 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
954 react on MIDI data arriving on certain MIDI input devices (so far only
955 Note-On and Note-Off events are sent via this LSCP event)
956 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
957 SET DB_INSTRUMENT FILE_PATH
958 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
959 frontends to send MIDI messages to specific sampler channel
960 - added two additional fields to GET FILE INSTRUMENT INFO command -
961 KEY_BINDINGS and KEYSWITCH_BINDINGS
962 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
963 was incorrect
964 - Optimized the retrieval of the MIDI instrument mappings
965 - added new LSCP command "SET VOICES" to globally alter the maximum
966 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
967 be triggered respectively
968 - added new LSCP command "SET STREAMS" to globally alter the maximum
969 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
970 which will be triggered respectively
971 - bugfix: retry if "select" returns EINTR (this fixes a crash when
972 a gigedit file dialog is opened)
973 - close all connections when LSCPServer is deleted
974 - hard close of all sockets on exit
975 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
976 driver
977
978 * Bug fixes:
979 - fixed a crash which occurs when removing a sampler channel waiting
980 to start instrument loading after another channel
981 - fixed a crash which occurs when removing a sampler channel with
982 instrument loading in progress (bug #113)
983 - fixed termination caused by uncaught exception when adding MIDI
984 instrument with PERSISTENT load mode
985 - fixed possible iterator invalidations when resetting the sampler
986 - fixed memory leaks when issuing the following LSCP commands:
987 GET AUDIO_OUTPUT_DRIVER INFO
988 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
989 GET MIDI_INPUT_DRIVER INFO
990 GET MIDI_INPUT_DRIVER_PARAMETER INFO
991 - fixed possible compilation error when sqlite is not present
992 - fixed orphaned pointers when setting maximum voices limit (bug #118)
993 - fixed crash when changing the audio output device of a sampler
994 channel with loaded instrument and start playing notes
995 - fixed endless loop in Engine::SuspendAll() (bug #120)
996 - fixed a low-level atomic load function that was broken on 64-bit
997 PowerPC, which probably could cause crashes on that platform
998 - fixed a memory management error which could cause a crash when a
999 plugin was unloaded
1000 - bugfix: two private structs had the same name, which could cause
1001 problems if the linker chose the wrong constructor
1002 - fixed low-level ConditionServer usage bug that caused lockups on
1003 Windows
1004
1005
1006 Version 0.5.1 (6 December 2007)
1007
1008 * packaging changes:
1009 - added autoconf checks for pthread library
1010 - added autoconf check for pthread bug found on certain NPTL-enabled
1011 glibc versions (see Gentoo bug report #194076)
1012 - added autoconf checks for MS Windows
1013
1014 * general changes:
1015 - bugfix: the thread used by an editor plugin didn't die when the
1016 editor closed
1017 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1018 out all the space. operator--() did not apply size_mask after
1019 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1020 order to avoid problems with the _NonVolatileReader functions.
1021 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1022 GetWriteSpace(). Since this function is currently only used in
1023 the stream's qsort() compare function, it didn't trigger any
1024 bugs.
1025 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1026 24bit mode too. Faster method to read 24bit words on little
1027 endian machines (x86): replaced 3 byte reads + shifts with a 1
1028 unaligned 32bit read and shift
1029 - experimental support for MS Windows (MIDI input via MME, AUDIO
1030 output via ASIO)
1031 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1032 - support for monitoring the total number of active disk streams
1033 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1034 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1035
1036 * AUDIO driver:
1037 - added Windows ASIO low latency audio driver
1038
1039 * MIDI driver:
1040 - added MME Windows MIDI driver
1041
1042 * LSCP server:
1043 - added support for Windows style path / filenames, however with
1044 forward slash path separators instead of backslash
1045 (i.e. "C:/foo/bar.gig")
1046 - allow naughty liblscp to send non-string device parameters within
1047 apostrophes as well
1048 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1049 "LIST FILE INSTRUMENTS <file>" and
1050 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1051 about an arbitrary instrument file on the system where the sampler is
1052 running on
1053
1054 Version 0.5.0 (15 October 2007)
1055
1056 * packaging changes:
1057 - config.h is not going to be installed along with liblinuxsampler's
1058 API header files anymore
1059 - only the API relevant header (and source) files will be exported to
1060 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1061 - added completely new XCode project files for Mac OSX which is now
1062 capable to execute our autoconf environment, thus no need anymore
1063 to maintain the compile time configuration file (osx/version.h) for
1064 OSX manually (patch by Toshi Nagata)
1065 - fixed buggy boolean --enable-foo / --disable-foo configure script
1066 parameters
1067 - global.h now only covers global definitions that are needed for the
1068 C++ API header files, all implementation internal global definitions
1069 are now in global_private.h
1070 - atomic.h is not exposed to the C++ API anymore
1071 - no need to include config.h anymore for using LS's API header files
1072 - fixed warnings in API doc generation
1073
1074 * general changes:
1075 - replaced the old, confusing MIDI program change mechanism by a
1076 flexible MIDI instrument mapper which allows to map arbitrary
1077 (MIDI bank, MIDI program) pairs with arbitrary
1078 (engine type, instrument file, file index) triplets which will be
1079 loaded on the respective channel when such MIDI program change
1080 messages arrive, beside that, each entry allows to define a life-time
1081 strategy for the instrument, so the user can define whether the
1082 instrument should i.e. be permanently loaded (to be able to switch
1083 quickly among sounds) or i.e. loaded just on demand when the
1084 respective program change arrives (to safe RAM space), as well as a
1085 global volume factor for each entry, so the user can adjust the volume
1086 dynamic of his mapped instrument collection without having to modify
1087 the instrument files, also one can manage arbitrary amount of such
1088 MIDI instrument maps and assign each sampler channel individually
1089 a certain map, so that i.e. separation of normal instruments and
1090 drumkits is possible
1091 - new notification events for tracking changes to audio/MIDI devices,
1092 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1093 - sampler was limited to load max. 200 instruments in the background
1094 due to a constant size RingBuffer FIFO which is now replaced by a
1095 dynamic (unlimited) size std::list FIFO
1096 - added FX sends, these allow to route audio signals to arbitrary audio
1097 output channels for being processed by external effect processors
1098 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1099 controllers
1100 - global (sampler wide) volume can now be controlled at runtime
1101 - Implemented new, improved notification system
1102 - fixed compilation errors regarding OSX
1103 (patch by Toshi Nagata)
1104 - implemented instruments database
1105 - added support for escape sequences to the instruments database
1106 - added highly experimental support for on-the-fly instrument editing
1107 within the sampler's process (by using instrument editor plugins),
1108 you'll notice the new "Registered instrument editors:" message on
1109 startup, added a new LSCP command:
1110 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1111 to spawn a matching instrument editor for the instrument on the
1112 given sampler channel, the plugin path can be overridden at compile
1113 time with ./configure --enable-plugin-dir=/some/dir
1114 - added experimental code for synchronizing instrument editors hosted
1115 in the sampler's process to safely edit instruments while playing
1116 without a crash (hopefully) by either suspending single regions
1117 wherever possible or if unavoidable whole engine(s)
1118 - fixed several issues in fundamental "Thread" class: set scheduling
1119 policy and priority on thread level, set a minimum stack size for
1120 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1121 threads simply inherited properties of starting thread instead of
1122 setting their own policy and priority
1123 - minor fix in our automatic stack trace mechanism on crashes, the
1124 main process did not wait for the stack trace process to finish
1125 its output
1126 - fixed some minor memory leaks
1127 - reenabled assembly features support, at the moment only for
1128 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1129 - minor assembly fix in x86 features detection (don't use the PIC
1130 register, to avoid relocations in the text segment at runtime)
1131 - POSIX callback functions of Thread.h are hidden
1132
1133 * MIDI driver:
1134 - dispatch bank select (MSB and LSB) messages
1135
1136 * audio driver:
1137 - the ALSA audio output driver parameters now reflect the correct
1138 parameter value ranges for the respective selected sound card
1139 (patch by Till Wimmer, a bit fixed and extended)
1140
1141 * Gigasampler format engine:
1142 - if a filter is used and EG2 finishes before EG1, let the voice
1143 die when EG2 has finished (this fixes a problem with clicks and
1144 voice starvation for some gigs)
1145 - playback is no longer disabled during instrument loading
1146 - all notes playing on a channel that changes its instrument keep
1147 playing with the old instrument until they get a note off
1148 command
1149 - EG fix: a release value of zero could cause noises or crash
1150 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1151 - EG fine tuning: when attack is zero the EG starts at a level
1152 above max sustain level, which means that there is a decay phase
1153 even if sustain is 100%
1154 - more EG fixes: the level could sometimes go below zero and cause
1155 noises or crashes
1156 - minor fix of EGDecay (patch by Toshi Nagata)
1157 - fixed compiler error when --enable-override-filter-type was
1158 supplied to the configure script (fixes #46)
1159 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1160 instead of a fix value
1161 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1162 127 (solo mode) only kill voices if the respective mode really
1163 changed
1164
1165 * LSCP server:
1166 - fixed compile time error for old Bison versions
1167 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1168 - parser now supports extended ASCII character set
1169 (up to ASCII code 255, i.e. includes now umlauts and accents)
1170 - filename arguments in LSCP commands now allow to use escape
1171 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1172 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1173 code value like \xf2) (fixes bug #24)
1174 - the following LSCP commands now also support escape sequences for at
1175 least one of their text-based parameters (i.e. name, description):
1176 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1177 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1178 "SET DB_INSTRUMENT_DIRECTORY NAME",
1179 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1180 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1181 "FIND DB_INSTRUMENT_DIRECTORIES"
1182 - returns verbose syntax errors (line and column where syntax error
1183 occured, the unexpected character and the actually expected, possible
1184 character(s), the latter only if less than 5 possibilities)
1185 - made sure that LSCP syntax is not affected by gigedit locale
1186 settings
1187 - bugfix regarding strings parameter lists: all comma separated lists
1188 of strings were treated as being one string containing commas
1189 (fixes #57)
1190
1191 * Bug fixes:
1192 - fixed crash occurring on certain LSCP scripts (Bug 39)
1193 - another thread safety fix for lscp "load engine" and "set
1194 channel audio output device"
1195 - fixed a crash which occurs when reassigning the same engine
1196 on a sampler channel with connected MIDI device
1197 - fixed a crash which occurs when changing the number of ports of a MIDI
1198 device connected to a sampler channel to number less then or equal
1199 to the index of the port to which the sampler channel is connected.
1200 - The previous bindings were not been disconnected when altering
1201 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1202 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1203 - The active stream/voice count statistic was incorrect.
1204 - notification events were not been sent for some sampler
1205 channel changes
1206 - added default min and max values to restrict the number of allowed
1207 audio output channels and MIDI input ports
1208 - the connection to the PCM interface is now closed when destroying
1209 an audio output device
1210 - files with slash in their path or filename could not be loaded
1211
1212 * test cases:
1213 - updated and fixed (haven't been touched in a while)
1214
1215 Version 0.4.0 (24 November 2006)
1216
1217 * packaging changes:
1218 - changed deprecated copyright attribute to license; added ldconfig
1219 to post-(un)install steps; added devel package for liblinuxsampler;
1220 to linuxsampler.spec (RPM)
1221 - install necessary development header files for allowing 3rd party
1222 applications to link against liblinuxsampler
1223 - liblinuxsampler's API documentation can be generated with 'make docs'
1224 (Doxygen required)
1225 - added benchmark to automatically detect the best triangle LFO
1226 implementation (currently either an integer math solution or a
1227 di-harmonic approximation), automatic detection can be overriden
1228 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1229 configure script argument though (mandatory for cross-compilation)
1230 - do not automatically pick optimized gcc flags if the user already
1231 provided some on his own (as CXXFLAGS)
1232 - added compile time option to disable processing of All-Notes-Off MIDI
1233 messages
1234 - added compile time options to allow disabling the various audio and
1235 MIDI drivers
1236 - fixed automatic GCC CPU switch detection on PPC
1237 (patch by Ebrahim Mayat)
1238
1239 * Gigasampler format engine:
1240 - extensive synthesis optimization
1241 (reimplementation of EGs and LFO(s), removed synthesis parameter
1242 prerendering and the synthesis parameter matrix in general, splitting
1243 each audio fragment into subfragments now where each subfragment uses
1244 constant pitch and filter coefficients. The volume coefficient is
1245 linearly interpolated inside a subfragment, unless
1246 --disable-interpolate-volume is set.)
1247 - fine tuning of the EG modulation parameters
1248 - improved filter cutoff calculation by adding support for the
1249 following gig parameters: Cutoff freq (used when no cutoff
1250 controller is defined), Control invert, Minimum cutoff, Velocity
1251 curve and Velocity range. The keyboard tracking now scales
1252 cutoff frequency instead of resonance.
1253 - added support for gig parameter Resonance.
1254 - fixed bug in sysex handling (patch by Juan Linietsky)
1255 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1256 which can be overridden with --enable-global-attenuation
1257 - EG fixes: made the length of "attack hold" stage more
1258 accurate. Release stage can now start before attack stage
1259 ends. Cancel release didn't work when sustain was zero. Attack
1260 time now has a minimal value to prevent clicks.
1261 - fixed pitch changes larger than one octave
1262 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1263 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1264 all modes can be altered via standard GM messages, that is CC5 for
1265 altering portamento time, CC65 for enabling / disabling portamento
1266 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1267 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1268 parameter) and crossfade
1269 - added support for the "attenuation controller threshold" gig
1270 parameter
1271 - added smoothing of volume changes caused by control change
1272 messages
1273 - sample loop parameters are now taken from the DimensionRegion
1274 instead of the wave chunk
1275 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1276 not equal to a power of two
1277 - reimplementation of the filter algorithm. The new filter is more
1278 accurate and supports all gig filter types, including bandreject
1279 and lowpass turbo.
1280 - real support for 24 bit samples - samples are not truncated to
1281 16 bits anymore
1282 - support for aftertouch (channel pressure, not polyphonic
1283 aftertouch)
1284 - LFO1 behaviour fixed (dampening from max volume instead of
1285 amplifying from 0)
1286
1287 * LSCP server:
1288 - fixed application exit on broken pipe error (fixes bug #20)
1289 - fixed the notification messages delay due to lack of
1290 network activity (fixes bug #26)
1291 - fixed parser bug which occured on space(s) within device parameters
1292 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1293
1294 * audio driver:
1295 - added aRts audio output driver (by no means RT safe)
1296
1297 * MIDI driver:
1298 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1299 messages several times instead of once
1300 - API extension for MIDI drivers which already supply exact time stamps
1301 for events (i.e. for offline rendering based MIDI drivers)
1302 - added checks for bad MIDI data
1303
1304 * linuxsampler application:
1305 - show available sampler engine types on startup
1306
1307 * general changes:
1308 - support for muting sampler channels and solo mode of the same, two new
1309 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1310 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1311 introduced for this, the behavior is the same like on a mixer console
1312 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1313 --enable-process-muted-channels which can be used to enable the
1314 processing of muted channels.
1315 - support for sostenuto pedal
1316 - support for monitoring the total number of active voices
1317 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1318 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1319 - fixed some memory management errors
1320 - fixed some concurrency problems that could lead to crashes when
1321 LSCP commands were executed
1322 - fixed crash when instrument loading failed previously on the same
1323 sampler channel (fixes bug #36)
1324
1325 Version 0.3.3 (15 July 2005)
1326
1327 * packaging changes:
1328 - fixed compilation with gcc 4.0
1329
1330 * Gigasampler format engine:
1331 - LFO preprocessing was performed even though the respective LFO was
1332 disabled by the instrument patch (minor efficiency fix)
1333 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1334 for volume ramp downs in the same fragment (needed for current voice
1335 stealing implementation) then simply inform the user with a warning
1336 about possible click sounds and reduce the volume ramp down
1337 appropriately instead of cancelling the audio device connection
1338
1339 Version 0.3.2 (24 June 2005)
1340
1341 * packaging changes:
1342 - updated autotools build files to compile on OS X
1343 (conditional compilation of CoreMIDI and MidiShare drivers)
1344 - hand-crafted assembly optimization code can be disabled with
1345 './configure --disable-asm' (definitely not recommended)
1346 - fixed 'make dist' rule to include all necessary files
1347 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1348 (due to 'dist-bzip2' automake option)
1349
1350 * Gigasampler format engine:
1351 - support for the gig parameters for "release velocity response" curves
1352 - fine tuning of the EGADSR envelope
1353 - volume of release triggered samples now depends on note-on velocity,
1354 note length and gig parameter "release trigger decay" instead of
1355 note-off velocity.
1356 - revised voice stealing
1357 (fixes crash and endless loop caused by voice stealing)
1358 - don't reset scale tuning on instrument or audio output device change
1359 - handle key group conflicts right at the beginning of each fragment
1360 instead of when the respective voice is actually launched
1361 (fixes undefined behavior if stolen voices belonged to a key group -
1362 this case was followed by a "killed voice survived" error message)
1363 - fixed minor issue with null/silence samples
1364 (those stole voices even though they don't need a voice at all which
1365 resulted in "voice stealing didn't work out" messages)
1366 - don't reset volume, pan, pitch and MIDI controller values on
1367 instrument or audio output device change
1368
1369 * LSCP server:
1370 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1371 - fixed LSCP event "CHANNEL_INFO" notification
1372 (e.g. did not notify on volume changes or MIDI program change events)
1373
1374 * linuxsampler application:
1375 - added command line parameters --lscp-addr and --lscp-port to override
1376 default IP address and port of LSCP server
1377
1378 Version 0.3.1 (24 May 2005)
1379
1380 * initial release
