* NKSP: Adjusted behavior of "change_vol()" and "change_tune()" to a more
  intuitive behavior if used in combination with "change_vol_time()" or
  "change_tune_time()" respectively: now tuning/volume changes are only
  assigned (without delay) immediately to a new note if the respective
  timing function has not been called before, otherwise the volume/tuning
  changes are automatically faded (before, only the event's time stamp was
  relevant).
* Bumped version (2.0.0.svn50).

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

210 - fixed linkage error when building with
211 LDFLAGS="-Wl,--no-undefined" (#190)
212 - fixed compilation with Clang 3.2
213 - removed usage of deprecated Automake variable INCLUDES
214 - fixed building with C++11

220 on the process's main thread
221 - fixed build error on newer MinGW
222 - support building with older jack versions
223 - support building with spaces in vst sdk path
224 - enabled automake 'subdir-objects' option and moved external
225 source references (vst, au, asio) from makefiles to cpp files,
226 in order to get rid of warnings from automake 1.14
227
228 * general changes:
229 - Refactoring: moved the independent code from
230 the Gigasampler format engine to base classes
231 - command line option '--profile' is currently disabled, since the
232 respective profiling code is currently broken
233 - Introduced support for optional environment variable
234 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
235 where the sampler shall look for instrument editor plugins
236 (patch by Luis Garrido, slightly modified).
237 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
238 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
239 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
240 note (in this implementation of the sampler its simply hard routed to
241 the 1st effect send of the sampler channel, no matter what the actual
242 effect type is)
243 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
244 note (in this implementation of the sampler its simply hard routed to
245 the 2nd effect send of the sampler channel, no matter what the actual
246 effect type is)
247 - implemented support for internal LADSPA effects
248 - raised limit of program change queue from 100 to 512
249 (as suggested by Alex Stone)
250 - implemented sine LFO, pulse LFO and saw LFO
251 - experimental support for per voice equalization
252 - added command line option --exec-after-init
253 - Introduced new C++ API method:
254 EngineChannel::InstrumentFileName(int index)
255 allowing to retrieve the whole list of files used for the loaded
256 instrument on an engine channel (a.k.a. part). Some GigaStudio
257 instruments for example are splitted over several files like
258 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
259 - Added new C++ API method Sampler::GetGlobalMaxVoices().
260 - Added new C++ API method Sampler::GetGlobalMaxStreams().
261 - Added new C++ API method Sampler::SetGlobalMaxVoices().
262 - Added new C++ API method Sampler::SetGlobalMaxStreams().
263 - Various "const" and "restrict" optimizations.
264 - all engines: add pan CC value to instrument pan parameter before
265 applying panning, instead of using two separate pan functions in
266 series (#182)
267 - added a lock guard class for exception safe mutex handling and
268 used it everywhere appropriate
269 - Immediately apply scale tuning changes to active voices.
270 - Exposed scale tuning to C++ API (along to the already existing standard
271 SysEx way).
272 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
273 and broken for ppc64. (Seq_cst loads and stores are actually not
274 used in LS, so the bug wasn't noticable.)
275 - lsatomic.h: added ARMv7 support
276 - Added support for multiple MIDI input ports per sampler channel (and
277 added various new C++ methods for this new feature / design change, old
278 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
279 as deprecated but are still there and should provide full behavior
280 backward compatibility).
281 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
282 unsafe and caused compilation error with clang 2.x).
283 - Bugfix: only process the latest MIDI program change event.
284 - Introducing the LSCP shell, which provides convenient control of the
285 sampler from the command line by providing LSCP aware features.
286 - VirtualMidiDevice: Added support for program change.
287 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
288 - VirtualMidiDevice: Added support for pitch bend.
289 - Aftertouch: extended API to explicitly handle channel pressure and
290 polyphonic key pressure events (so far polyphonic pressure was not
291 supported at all, and channel pressure was rerouted as CC128 but not
292 used so far).
293 - Added initial support for real-time instrument scripts. The script VM
294 code is shared by all sampler engine implemementations, however only the
295 gig file format currently provides support for storing instrument scripts
296 (as LinuxSampler extension to the original GigaStudio 4 format).
297
298 * Gigasampler format engine:
299 - implemented the "round robin keyboard" dimension
300 - fixed round robin and random dimensions for cases when number of
301 dimension zones is not a power of two
302 - made round robin use a counter for each region instead of each
303 key
304 - bugfix: pitch LFO controller "internal+aftertouch" was broken
305 - bugfix: filter keyboard tracking was broken
306 - filter performance fix (an unnecessary copy was made of the
307 filter parameters in each sub fragment)
308 - handle special case when pan parameter in gig file has max or
309 min value
310 - Exclusive Groups: don't ever stop voices of the same note,
311 doesn't sound naturally with a drumkit
312 - fixed EG1 modulation when attack or release is zero
313 - Fixed support for 'aftertouch' attenuation controller.
314 - Fixed crash that happened with velocity split sounds under certain
315 conditions (see also previous commit on libgig).
316 - fixed behaviour of filter LFO
317
318 * SFZ format engine:
319 - Initial implementation (not usable yet)
320 - added support for v2 multiple stage envelope generators
321 - added a fine-tuned v1 envelope generator instead of using the
322 one from the gig engine

324 - added support for trigger=first, trigger=legato and sw_previous
325 - allow non-numerical key values ("C#4" for example)

327 - fixed error when unloading instrument with same sample used by
328 multiple regions
329 - added some opcode aliases, like loopmode for loop_mode, to be
330 more compatible
331 - added support for trigger=release and rt_decay

344 - optimized sample lookup
345 - improved support for exclusive groups (group, off_by and
346 off_mode)
347 - added support for controller triggered regions (on_locc/on_hicc)
348 - added support for loop_mode=one_shot
349 - fixed playback of 16 bit wav files on big endian CPUs
350 - added support for Ogg Vorbis sample files
351 - use loop markers from sample file if loop_start and loop_end are
352 not set in sfz file
353 - implemeted filters. Filter types: lowpass, bandpass, bandreject
354 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
355 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
356 cutoff_cc, cutoff_chanaft.
357 - bugfix: zero ampeg_sustain didn't work

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

673 - Pass/preserve polyphonic variable data from respective "note" event
674 handler to "release" event handler.

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

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

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

735 "./configure --disable-jack-driver" was used
736 (patch by Alexis Ballier)
737 - fixed compilation with gcc 4.3
738 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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

811 win64)
812 - VST: added support for sample rate and buffer size changes
813 - VST: close editor (Fantasia) when the VST is removed
814 - VST: avoid opening Fantasia more than once for each VST instance

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

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