* NKSP: Implemented built-in script function "change_vol_curve()".
* NKSP: Implemented built-in script function "change_tune_curve()".
* NKSP: Added built-in script constant "$NKSP_LINEAR".
* NKSP: Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
* Bumped version (2.0.0.svn54).

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

236 in order to get rid of warnings from automake 1.14
237
238 * general changes:
239 - Refactoring: moved the independent code from
240 the Gigasampler format engine to base classes
241 - command line option '--profile' is currently disabled, since the
242 respective profiling code is currently broken
243 - Introduced support for optional environment variable
244 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
245 where the sampler shall look for instrument editor plugins
246 (patch by Luis Garrido, slightly modified).
247 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
248 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
249 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
250 note (in this implementation of the sampler its simply hard routed to
251 the 1st effect send of the sampler channel, no matter what the actual
252 effect type is)
253 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
254 note (in this implementation of the sampler its simply hard routed to
255 the 2nd effect send of the sampler channel, no matter what the actual
256 effect type is)
257 - implemented support for internal LADSPA effects
258 - raised limit of program change queue from 100 to 512
259 (as suggested by Alex Stone)
260 - implemented sine LFO, pulse LFO and saw LFO
261 - experimental support for per voice equalization
262 - added command line option --exec-after-init
263 - Introduced new C++ API method:
264 EngineChannel::InstrumentFileName(int index)
265 allowing to retrieve the whole list of files used for the loaded
266 instrument on an engine channel (a.k.a. part). Some GigaStudio
267 instruments for example are splitted over several files like
268 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
269 - Added new C++ API method Sampler::GetGlobalMaxVoices().
270 - Added new C++ API method Sampler::GetGlobalMaxStreams().
271 - Added new C++ API method Sampler::SetGlobalMaxVoices().
272 - Added new C++ API method Sampler::SetGlobalMaxStreams().
273 - Various "const" and "restrict" optimizations.
274 - all engines: add pan CC value to instrument pan parameter before
275 applying panning, instead of using two separate pan functions in
276 series (#182)
277 - added a lock guard class for exception safe mutex handling and
278 used it everywhere appropriate
279 - Immediately apply scale tuning changes to active voices.
280 - Exposed scale tuning to C++ API (along to the already existing standard
281 SysEx way).
282 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
283 and broken for ppc64. (Seq_cst loads and stores are actually not
284 used in LS, so the bug wasn't noticable.)
285 - lsatomic.h: added ARMv7 support
286 - Added support for multiple MIDI input ports per sampler channel (and
287 added various new C++ methods for this new feature / design change, old
288 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
289 as deprecated but are still there and should provide full behavior
290 backward compatibility).
291 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
292 unsafe and caused compilation error with clang 2.x).
293 - Bugfix: only process the latest MIDI program change event.
294 - Introducing the LSCP shell, which provides convenient control of the
295 sampler from the command line by providing LSCP aware features.
296 - VirtualMidiDevice: Added support for program change.
297 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
298 - VirtualMidiDevice: Added support for pitch bend.
299 - Aftertouch: extended API to explicitly handle channel pressure and
300 polyphonic key pressure events (so far polyphonic pressure was not
301 supported at all, and channel pressure was rerouted as CC128 but not
302 used so far).
303 - Added initial support for real-time instrument scripts. The script VM
304 code is shared by all sampler engine implemementations, however only the
305 gig file format currently provides support for storing instrument scripts
306 (as LinuxSampler extension to the original GigaStudio 4 format).
307
308 * Gigasampler format engine:
309 - implemented the "round robin keyboard" dimension
310 - fixed round robin and random dimensions for cases when number of
311 dimension zones is not a power of two
312 - made round robin use a counter for each region instead of each
313 key
314 - bugfix: pitch LFO controller "internal+aftertouch" was broken
315 - bugfix: filter keyboard tracking was broken
316 - filter performance fix (an unnecessary copy was made of the
317 filter parameters in each sub fragment)
318 - handle special case when pan parameter in gig file has max or
319 min value
320 - Exclusive Groups: don't ever stop voices of the same note,
321 doesn't sound naturally with a drumkit
322 - fixed EG1 modulation when attack or release is zero
323 - Fixed support for 'aftertouch' attenuation controller.
324 - Fixed crash that happened with velocity split sounds under certain
325 conditions (see also previous commit on libgig).
326 - fixed behaviour of filter LFO
327
328 * SFZ format engine:
329 - Initial implementation (not usable yet)
330 - added support for v2 multiple stage envelope generators
331 - added a fine-tuned v1 envelope generator instead of using the
332 one from the gig engine
333 - fixed memory leak and memory handling errors
334 - added support for trigger=first, trigger=legato and sw_previous
335 - allow non-numerical key values ("C#4" for example)
336 - "key" opcode now sets pitch_keycenter too
337 - fixed error when unloading instrument with same sample used by
338 multiple regions
339 - added some opcode aliases, like loopmode for loop_mode, to be
340 more compatible
341 - added support for trigger=release and rt_decay
342 - added support for off_mode=normal
343 - added support for random, seq_position, seq_length and volume
344 - added v1 LFO opcodes to parser (no support in engine yet)
345 - added support for amp_veltrack and amp_velcurve_N
346 - fine-tuned the default velocity curve
347 - added support for transpose
348 - fixed crash when using sw_down/up
349 - improved logic for sw_lokey/hikey/up/down/last
350 - added more v1 aliases to parser
351 - reduced memory usage for sfz data
352 - RT-safeness: avoid malloc in audio thread
353 - fixed a bug that could cause voice stealing to fail
354 - optimized sample lookup
355 - improved support for exclusive groups (group, off_by and
356 off_mode)
357 - added support for controller triggered regions (on_locc/on_hicc)
358 - added support for loop_mode=one_shot
359 - fixed playback of 16 bit wav files on big endian CPUs
360 - added support for Ogg Vorbis sample files
361 - use loop markers from sample file if loop_start and loop_end are
362 not set in sfz file
363 - implemeted filters. Filter types: lowpass, bandpass, bandreject
364 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
365 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
366 cutoff_cc, cutoff_chanaft.
367 - bugfix: zero ampeg_sustain didn't work

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

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

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

756 directory above)
757 - configure script fix: removed unconditional use of SSE
758 - fixed building with sqlite installed in a non-standard directory
759 - when cross-compiling, don't try to create instruments.db
760 - fix for new mingw-w64 version, which has usleep
761
762 * general changes:
763 - bugfix: on some POSIX systems instrument editor plugins refused to
764 load as we used a non-portable Linux specific struct field
765 (fixes bug #70, patch by Ronald Baljeu)
766 - fixed endless loop which occured when loading an instrument editor
767 plugin DLL on Windows systems failed
768 - fixed memory leaks that occurred when liblinuxsampler was unloaded
769 - optimized the SynchronizedConfig class so it doesn't wait
770 unnecessarily long after an update

772 events (e.g. to highlight the pressed keys on the virtual keyboard
773 of gigedit)
774 - added support for triggering notes by instrument editors (see above)
775 - be verbose on DLL load errors (on Linux)
776 - fixed di-harmonic triangle LFO implementation (this LFO implementation
777 is only used by very few systems, most pick the int math
778 implementation, which is usually faster)
779 - fixes for audio drivers with varying buffer sizes
780 - experimental support for running LinuxSampler as a DSSI, LV2 and
781 VST plugin
782 - notification events for stream/voice count statistics are now sent
783 only when there are actual changes

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

826 energyXT)
827 - VST: changed number of output channels from one stereo to 16
828 stereo
829 - added channel routing, fxsends and midi maps to the settings
830 stored in the plugin state
831 - performance optimization of AudioChannel::MixTo() and
832 AudioChannel::CopyTo() methods using GCC vector exensions
833 (if available)
834 - ASIO fixes: avoid initializing the device twice, avoid throwing
835 exception when getting parameters from a disconnected device
836
837 * MIDI driver:
838 - added JACK MIDI driver
839 - dispatch bank select as ordinary CC as well, the user might seriously
840 want to (mis)use it for some purpose ("fixed" in all current MIDI

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

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