File size: 72145 byte(s)
* NKSP Fix: Never suspend "init" event handlers.
* NKSP: Implemented built-in script function "array_equal()".
* NKSP: Implemented built-in script function "search()".
* NKSP: Implemented built-in script function "sort()".
* Bumped version (2.0.0.svn52).

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

214 - fixed linkage error when building with
215 LDFLAGS="-Wl,--no-undefined" (#190)
216 - fixed compilation with Clang 3.2
217 - removed usage of deprecated Automake variable INCLUDES

224 on the process's main thread
225 - fixed build error on newer MinGW
226 - support building with older jack versions
227 - support building with spaces in vst sdk path
228 - enabled automake 'subdir-objects' option and moved external
229 source references (vst, au, asio) from makefiles to cpp files,
230 in order to get rid of warnings from automake 1.14
231
232 * general changes:
233 - Refactoring: moved the independent code from
234 the Gigasampler format engine to base classes
235 - command line option '--profile' is currently disabled, since the
236 respective profiling code is currently broken
237 - Introduced support for optional environment variable
238 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
239 where the sampler shall look for instrument editor plugins
240 (patch by Luis Garrido, slightly modified).
241 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
242 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
243 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
244 note (in this implementation of the sampler its simply hard routed to
245 the 1st effect send of the sampler channel, no matter what the actual
246 effect type is)
247 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
248 note (in this implementation of the sampler its simply hard routed to
249 the 2nd effect send of the sampler channel, no matter what the actual
250 effect type is)
251 - implemented support for internal LADSPA effects
252 - raised limit of program change queue from 100 to 512
253 (as suggested by Alex Stone)
254 - implemented sine LFO, pulse LFO and saw LFO
255 - experimental support for per voice equalization
256 - added command line option --exec-after-init
257 - Introduced new C++ API method:
258 EngineChannel::InstrumentFileName(int index)
259 allowing to retrieve the whole list of files used for the loaded
260 instrument on an engine channel (a.k.a. part). Some GigaStudio
261 instruments for example are splitted over several files like
262 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
263 - Added new C++ API method Sampler::GetGlobalMaxVoices().
264 - Added new C++ API method Sampler::GetGlobalMaxStreams().
265 - Added new C++ API method Sampler::SetGlobalMaxVoices().
266 - Added new C++ API method Sampler::SetGlobalMaxStreams().
267 - Various "const" and "restrict" optimizations.
268 - all engines: add pan CC value to instrument pan parameter before
269 applying panning, instead of using two separate pan functions in
270 series (#182)
271 - added a lock guard class for exception safe mutex handling and
272 used it everywhere appropriate
273 - Immediately apply scale tuning changes to active voices.
274 - Exposed scale tuning to C++ API (along to the already existing standard
275 SysEx way).
276 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
277 and broken for ppc64. (Seq_cst loads and stores are actually not
278 used in LS, so the bug wasn't noticable.)
279 - lsatomic.h: added ARMv7 support
280 - Added support for multiple MIDI input ports per sampler channel (and
281 added various new C++ methods for this new feature / design change, old
282 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
283 as deprecated but are still there and should provide full behavior
284 backward compatibility).
285 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
286 unsafe and caused compilation error with clang 2.x).
287 - Bugfix: only process the latest MIDI program change event.
288 - Introducing the LSCP shell, which provides convenient control of the
289 sampler from the command line by providing LSCP aware features.
290 - VirtualMidiDevice: Added support for program change.
291 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
292 - VirtualMidiDevice: Added support for pitch bend.
293 - Aftertouch: extended API to explicitly handle channel pressure and
294 polyphonic key pressure events (so far polyphonic pressure was not
295 supported at all, and channel pressure was rerouted as CC128 but not
296 used so far).
297 - Added initial support for real-time instrument scripts. The script VM
298 code is shared by all sampler engine implemementations, however only the
299 gig file format currently provides support for storing instrument scripts
300 (as LinuxSampler extension to the original GigaStudio 4 format).
301
302 * Gigasampler format engine:
303 - implemented the "round robin keyboard" dimension
304 - fixed round robin and random dimensions for cases when number of
305 dimension zones is not a power of two
306 - made round robin use a counter for each region instead of each
307 key
308 - bugfix: pitch LFO controller "internal+aftertouch" was broken
309 - bugfix: filter keyboard tracking was broken
310 - filter performance fix (an unnecessary copy was made of the
311 filter parameters in each sub fragment)
312 - handle special case when pan parameter in gig file has max or
313 min value
314 - Exclusive Groups: don't ever stop voices of the same note,
315 doesn't sound naturally with a drumkit
316 - fixed EG1 modulation when attack or release is zero
317 - Fixed support for 'aftertouch' attenuation controller.
318 - Fixed crash that happened with velocity split sounds under certain
319 conditions (see also previous commit on libgig).
320 - fixed behaviour of filter LFO
321
322 * SFZ format engine:
323 - Initial implementation (not usable yet)
324 - added support for v2 multiple stage envelope generators
325 - added a fine-tuned v1 envelope generator instead of using the
326 one from the gig engine
327 - fixed memory leak and memory handling errors
328 - added support for trigger=first, trigger=legato and sw_previous
329 - allow non-numerical key values ("C#4" for example)
330 - "key" opcode now sets pitch_keycenter too
331 - fixed error when unloading instrument with same sample used by
332 multiple regions
333 - added some opcode aliases, like loopmode for loop_mode, to be
334 more compatible
335 - added support for trigger=release and rt_decay
336 - added support for off_mode=normal
337 - added support for random, seq_position, seq_length and volume
338 - added v1 LFO opcodes to parser (no support in engine yet)
339 - added support for amp_veltrack and amp_velcurve_N
340 - fine-tuned the default velocity curve
341 - added support for transpose
342 - fixed crash when using sw_down/up
343 - improved logic for sw_lokey/hikey/up/down/last
344 - added more v1 aliases to parser
345 - reduced memory usage for sfz data
346 - RT-safeness: avoid malloc in audio thread
347 - fixed a bug that could cause voice stealing to fail
348 - optimized sample lookup
349 - improved support for exclusive groups (group, off_by and
350 off_mode)
351 - added support for controller triggered regions (on_locc/on_hicc)
352 - added support for loop_mode=one_shot
353 - fixed playback of 16 bit wav files on big endian CPUs
354 - added support for Ogg Vorbis sample files
355 - use loop markers from sample file if loop_start and loop_end are
356 not set in sfz file
357 - implemeted filters. Filter types: lowpass, bandpass, bandreject
358 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
359 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
360 cutoff_cc, cutoff_chanaft.
361 - bugfix: zero ampeg_sustain didn't work

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

690 - bugfix: calling SET VOICES (which Fantasia does on start and
691 refresh) could cause instruments to be unloaded
692 - Mac OS X: fixed name collision of enum in EffectControl and
693 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
694 - Mac OS X: fixed hanging threads
695 - Windows: disabled the previous thread fix on non-Mac systems, as
696 it caused hanging threads on Windows
697 - Fixed possible crashes due to corrupted MIDI/audio device list
698 after MIDI/audio device creation failure
699 - When creating MIDI instrument map entries with "PERSISTENT" type, the
700 instruments were uselessly precached with zero samples, however it still
701 took the full preloading time and on 1st program change the respective
702 instrument was completely reloaded again.

704 sent to the same sampler channel (patch from the Open Octave
705 project, slightly adjusted)

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

750 directory above)
751 - configure script fix: removed unconditional use of SSE
752 - fixed building with sqlite installed in a non-standard directory
753 - when cross-compiling, don't try to create instruments.db
754 - fix for new mingw-w64 version, which has usleep
755
756 * general changes:
757 - bugfix: on some POSIX systems instrument editor plugins refused to
758 load as we used a non-portable Linux specific struct field
759 (fixes bug #70, patch by Ronald Baljeu)
760 - fixed endless loop which occured when loading an instrument editor
761 plugin DLL on Windows systems failed
762 - fixed memory leaks that occurred when liblinuxsampler was unloaded
763 - optimized the SynchronizedConfig class so it doesn't wait
764 unnecessarily long after an update
765 - added support for notifying instrument editors on note-on / note-off
766 events (e.g. to highlight the pressed keys on the virtual keyboard
767 of gigedit)
768 - added support for triggering notes by instrument editors (see above)
769 - be verbose on DLL load errors (on Linux)
770 - fixed di-harmonic triangle LFO implementation (this LFO implementation
771 is only used by very few systems, most pick the int math
772 implementation, which is usually faster)
773 - fixes for audio drivers with varying buffer sizes
774 - experimental support for running LinuxSampler as a DSSI, LV2 and
775 VST plugin
776 - notification events for stream/voice count statistics are now sent
777 only when there are actual changes
778 - added memory ordering constraints to improve stability on
779 multi-core and multi-cpu systems
780 - maximum voices and disk streams can now be altered at runtime
781 - fixed CPU feature detection on x86_64 (maybe fixes #108)
782 - automatic stacktrace mechanism is now turned off by default and can
783 be switched on by command line option "--stacktrace" (the automatic
784 stacktrace mechanism seems to be broken on most systems at the moment)
785 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
786 a pointer to the launched InstrumentEditor object
787 - added optional 3rd party user data parameter for following
788 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
789 InstrumentEditor::Launch(),
790 InstrumentManager::LaunchInstrumentEditor()
791 - theoretical fix: made SynchronizedConfig follow C++0x memory
792 model more strictly
793 - fixes for using large audio device buffers
794 - Windows: add the installation directory to the DLL search path
795 when loading an editor plugin (solves problems with VST and
796 gigedit on systems with other GTK versions installed)
797 - updated linuxsampler man page
798
799 * audio driver:
800 - removed the nonsense audio channel constraint (which was hard coded to
801 max. 100 audio channels) for most audio drivers
802 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
803 opposed to the LSCP specs
804 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
805 reflected the wrong value
806 - fixed a memory management bug in ASIO driver
807 - Makefile fix: JACK_CFLAGS wasn't used
808 - JACK: use jack_client_open instead of the deprecated
809 jack_client_new

815 win64)
816 - VST: added support for sample rate and buffer size changes
817 - VST: close editor (Fantasia) when the VST is removed
818 - VST: avoid opening Fantasia more than once for each VST instance

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

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