* NKSP: Built-in "ignore_event()" function: argument is now optional,
  like with built-in function "ignore_controller()".

1 Version SVN trunk (?)
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.
11 * Gigasampler/GigaStudio format engine:
12 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13 cutoff settings.
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.
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.
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.

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()".
169 * Instruments DB:
170 - Fixed memory access bug of general DB access code which lead to
171 undefined behavior.
172 - Cleanup of instruments DB file creation and opening code.
173 - The instrument DB path of linuxsampler's --create-instruments-db argument
174 is now optional, if it is missing, then a default location is used.
175 - Added support for scanning SFZ (.sfz) files.
176 - Added support for scanning Sound Font (.sf2) files.
177 - Fixed undefined DB transaction behavior.

201 - fixed linkage error when building with
202 LDFLAGS="-Wl,--no-undefined" (#190)

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

327 - fine-tuned the default velocity curve
328 - added support for transpose
329 - fixed crash when using sw_down/up
330 - improved logic for sw_lokey/hikey/up/down/last
331 - added more v1 aliases to parser
332 - reduced memory usage for sfz data
333 - RT-safeness: avoid malloc in audio thread
334 - fixed a bug that could cause voice stealing to fail
335 - optimized sample lookup
336 - improved support for exclusive groups (group, off_by and
337 off_mode)
338 - added support for controller triggered regions (on_locc/on_hicc)
339 - added support for loop_mode=one_shot
340 - fixed playback of 16 bit wav files on big endian CPUs
341 - added support for Ogg Vorbis sample files
342 - use loop markers from sample file if loop_start and loop_end are
343 not set in sfz file
344 - implemeted filters. Filter types: lowpass, bandpass, bandreject
345 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
346 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
347 cutoff_cc, cutoff_chanaft.
348 - bugfix: zero ampeg_sustain didn't work
349 - added support for velocity effect on amplifier envelope time
350 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
351 ampeg_vel2release)
352 - added support for EG hold (ampeg_hold)

539 - added support for MIDI note on velocity filter
540 - CoreMIDI: fixed memory deallocation error
541 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
542 virtual keyboards in frontends / instrument editors being stuck.

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

672 channel to a different engine type
673 - fixed crash when deleting a sampler channel or changing engine
674 type while an instrument load was in progress
675 - bugfix: playing a note while changing the instrument could cause
676 a crash, or give "Handing back unknown region" error messages
677 - bugfix: calling SET VOICES (which Fantasia does on start and
678 refresh) could cause instruments to be unloaded
679 - Mac OS X: fixed name collision of enum in EffectControl and
680 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
681 - Mac OS X: fixed hanging threads
682 - Windows: disabled the previous thread fix on non-Mac systems, as
683 it caused hanging threads on Windows
684 - Fixed possible crashes due to corrupted MIDI/audio device list
685 after MIDI/audio device creation failure
686 - When creating MIDI instrument map entries with "PERSISTENT" type, the
687 instruments were uselessly precached with zero samples, however it still
688 took the full preloading time and on 1st program change the respective
689 instrument was completely reloaded again.
690 - fixed handling of rapid bank select and program change messages
691 sent to the same sampler channel (patch from the Open Octave
692 project, slightly adjusted)

711 crashes and noise on such transitions).
712 - ignore missing LADSPA paths without ignoring valid LADSPA paths
713 (fixes #208)
714 - Fixed bug in LSCP grammar definition which caused a statement like
715 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
716 practically irrelevant, however it caused problems with the new LSCP
717 shell's auto completion feature).
718 - Fixed MIDI program change messages being ignored if quickly executed
719 after each other (fixes #231).
721 Version 1.0.0 (31 July 2009)
723 * packaging changes:

736 directory of liblinuxsampler dll (look in the same directory and one
737 directory above)
738 - configure script fix: removed unconditional use of SSE
739 - fixed building with sqlite installed in a non-standard directory
740 - when cross-compiling, don't try to create instruments.db
741 - fix for new mingw-w64 version, which has usleep
743 * general changes:
744 - bugfix: on some POSIX systems instrument editor plugins refused to
745 load as we used a non-portable Linux specific struct field
746 (fixes bug #70, patch by Ronald Baljeu)
747 - fixed endless loop which occured when loading an instrument editor
748 plugin DLL on Windows systems failed
749 - fixed memory leaks that occurred when liblinuxsampler was unloaded
750 - optimized the SynchronizedConfig class so it doesn't wait
751 unnecessarily long after an update

753 events (e.g. to highlight the pressed keys on the virtual keyboard
754 of gigedit)
755 - added support for triggering notes by instrument editors (see above)
756 - be verbose on DLL load errors (on Linux)
757 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

802 win64)
803 - VST: added support for sample rate and buffer size changes
804 - VST: close editor (Fantasia) when the VST is removed
805 - VST: avoid opening Fantasia more than once for each VST instance

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

837 - work-around for missing fnmatch function on Windows to make
838 instrument database compilable
839 - added instrument database support on Windows
840 works with both standalone mode and VST plugin.
841 the instruments DB file is located in
842 %USERPROFILE%\.linuxsampler\instruments.db which allows different
843 databases for each windows user
844 if no DB is present it automatically creates the .linuxsampler subdir
845 and then creates an empty DB
846 - fixed recursive import, which was broken on Windows
848 * Gigasampler format engine:
849 - fixed a memory leak that could happen when a channel was deleted
850 while notes were playing
851 - made it possible to load an instrument even if the audio thread
852 isn't running
853 - added partial support for the "Controller Triggered" MIDI rule,
854 enough for piano gigs with pedal noise samples
855 - minor fix: only mark FX sends as being modified if really the
856 respective FX send MIDI controller was used
857 - added support for GM global device volume SysEx message
858 (can be selected at compile time to either apply globally to the
859 whole sampler [default] or only to the sampler channels that are
860 connected to the respective MIDI input port the SysEx message arrived
861 on)
862 - bugfix: notes triggered at position 0 in the audio buffer were
863 sometimes wrongly killed in the same buffer, causing no sound to
864 be played
865 - added support for chromatic / drumkit mode Roland GS Sysex message
866 which is usally used to switch a part between chromatic sounds and
867 drumkit sounds (as opposed to their common default setting of MIDI
868 part 10 being a drumkit part and all other ones chromatic parts), in
869 LS however one can switch between the first 16 MIDI instrument maps
870 defined for the sampler
871 - made it possible to create multiple sample channels even if the
872 audio thread isn't running
873 - fixed crash when removing channel with active voices (#116)
874 - bugfix: on sample reference changes (instrument editor), only
875 un-cache the respective sample if it's really not used by any
876 sampler engine anymore
877 - re-cache samples in case they were changed by an instrument editor,
878 e.g. when a sample was added while playing (#82)
879 - fixed hanging notes which occured when note-off event had the exact
880 same time stamp as the voice's note-on event and occured both in the
881 same audio fragment cycle (fixes bug #112)
882 - added support for the "fine tune" and "pitch bend range"
883 instrument-level gig parameters
884 - fixed minor artifacts in pitch bend handling
885 - added support for GS Reset SysEx message
886 - allow gig files to use unlimited downward pitch shifting
887 - added a limit check for upward pitch shifting
888 - bugfix: sometimes, when playing a note twice fast, the second
889 note was silent
890 - fixed crash happening when a pitch bend event arrived at the
891 same time a new instrument was loading
893 * LSCP server:
894 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
895 react on MIDI data arriving on certain sampler channels (so far only
896 Note-On and Note-Off events are sent via this LSCP event)
897 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
898 react on MIDI data arriving on certain MIDI input devices (so far only
899 Note-On and Note-Off events are sent via this LSCP event)
900 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
902 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
903 frontends to send MIDI messages to specific sampler channel
904 - added two additional fields to GET FILE INSTRUMENT INFO command -
906 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
907 was incorrect
908 - Optimized the retrieval of the MIDI instrument mappings
909 - added new LSCP command "SET VOICES" to globally alter the maximum
910 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
911 be triggered respectively
912 - added new LSCP command "SET STREAMS" to globally alter the maximum
913 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
914 which will be triggered respectively
915 - bugfix: retry if "select" returns EINTR (this fixes a crash when
916 a gigedit file dialog is opened)
917 - close all connections when LSCPServer is deleted
918 - hard close of all sockets on exit
919 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
920 driver
922 * Bug fixes:
923 - fixed a crash which occurs when removing a sampler channel waiting
924 to start instrument loading after another channel
925 - fixed a crash which occurs when removing a sampler channel with
926 instrument loading in progress (bug #113)
927 - fixed termination caused by uncaught exception when adding MIDI
928 instrument with PERSISTENT load mode
929 - fixed possible iterator invalidations when resetting the sampler
930 - fixed memory leaks when issuing the following LSCP commands:
935 - fixed possible compilation error when sqlite is not present
936 - fixed orphaned pointers when setting maximum voices limit (bug #118)
937 - fixed crash when changing the audio output device of a sampler
938 channel with loaded instrument and start playing notes
939 - fixed endless loop in Engine::SuspendAll() (bug #120)
940 - fixed a low-level atomic load function that was broken on 64-bit
941 PowerPC, which probably could cause crashes on that platform
942 - fixed a memory management error which could cause a crash when a
943 plugin was unloaded
944 - bugfix: two private structs had the same name, which could cause
945 problems if the linker chose the wrong constructor
946 - fixed low-level ConditionServer usage bug that caused lockups on
947 Windows
950 Version 0.5.1 (6 December 2007)
952 * packaging changes:
953 - added autoconf checks for pthread library
954 - added autoconf check for pthread bug found on certain NPTL-enabled
955 glibc versions (see Gentoo bug report #194076)
956 - added autoconf checks for MS Windows
958 * general changes:
959 - bugfix: the thread used by an editor plugin didn't die when the
960 editor closed
961 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
962 out all the space. operator--() did not apply size_mask after
963 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
964 order to avoid problems with the _NonVolatileReader functions.
965 - bugfix: Stream.h: added a missing divide by BytesPerSample in
966 GetWriteSpace(). Since this function is currently only used in
967 the stream's qsort() compare function, it didn't trigger any
968 bugs.
969 - Resampler.h, Synthesizer.h: cubic interpolation now works in
970 24bit mode too. Faster method to read 24bit words on little
971 endian machines (x86): replaced 3 byte reads + shifts with a 1
972 unaligned 32bit read and shift
973 - experimental support for MS Windows (MIDI input via MME, AUDIO
974 output via ASIO)
975 - made handling of SIGINT signal (Ctrl-C) a bit more robust
976 - support for monitoring the total number of active disk streams
977 (new LSCP commands: GET TOTAL_STREAM_COUNT,
980 * AUDIO driver:
981 - added Windows ASIO low latency audio driver
983 * MIDI driver:
984 - added MME Windows MIDI driver
986 * LSCP server:
987 - added support for Windows style path / filenames, however with
988 forward slash path separators instead of backslash
989 (i.e. "C:/foo/bar.gig")
990 - allow naughty liblscp to send non-string device parameters within
991 apostrophes as well
992 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
993 "LIST FILE INSTRUMENTS <file>" and
994 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
995 about an arbitrary instrument file on the system where the sampler is
996 running on
998 Version 0.5.0 (15 October 2007)
1000 * packaging changes:
1001 - config.h is not going to be installed along with liblinuxsampler's
1002 API header files anymore
1003 - only the API relevant header (and source) files will be exported to
1004 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1005 - added completely new XCode project files for Mac OSX which is now
1006 capable to execute our autoconf environment, thus no need anymore
1007 to maintain the compile time configuration file (osx/version.h) for
1008 OSX manually (patch by Toshi Nagata)
1009 - fixed buggy boolean --enable-foo / --disable-foo configure script
1010 parameters
1011 - global.h now only covers global definitions that are needed for the
1012 C++ API header files, all implementation internal global definitions
1013 are now in global_private.h
1014 - atomic.h is not exposed to the C++ API anymore
1015 - no need to include config.h anymore for using LS's API header files
1016 - fixed warnings in API doc generation
1018 * general changes:
1019 - replaced the old, confusing MIDI program change mechanism by a
1020 flexible MIDI instrument mapper which allows to map arbitrary
1021 (MIDI bank, MIDI program) pairs with arbitrary
1022 (engine type, instrument file, file index) triplets which will be
1023 loaded on the respective channel when such MIDI program change
1024 messages arrive, beside that, each entry allows to define a life-time
1025 strategy for the instrument, so the user can define whether the
1026 instrument should i.e. be permanently loaded (to be able to switch
1027 quickly among sounds) or i.e. loaded just on demand when the
1028 respective program change arrives (to safe RAM space), as well as a
1029 global volume factor for each entry, so the user can adjust the volume
1030 dynamic of his mapped instrument collection without having to modify
1031 the instrument files, also one can manage arbitrary amount of such
1032 MIDI instrument maps and assign each sampler channel individually
1033 a certain map, so that i.e. separation of normal instruments and
1034 drumkits is possible
1035 - new notification events for tracking changes to audio/MIDI devices,
1036 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1037 - sampler was limited to load max. 200 instruments in the background
1038 due to a constant size RingBuffer FIFO which is now replaced by a
1039 dynamic (unlimited) size std::list FIFO
1040 - added FX sends, these allow to route audio signals to arbitrary audio
1041 output channels for being processed by external effect processors
1042 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1043 controllers
1044 - global (sampler wide) volume can now be controlled at runtime
1045 - Implemented new, improved notification system
1046 - fixed compilation errors regarding OSX
1047 (patch by Toshi Nagata)
1048 - implemented instruments database
1049 - added support for escape sequences to the instruments database
1050 - added highly experimental support for on-the-fly instrument editing
1051 within the sampler's process (by using instrument editor plugins),
1052 you'll notice the new "Registered instrument editors:" message on
1053 startup, added a new LSCP command:
1054 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1055 to spawn a matching instrument editor for the instrument on the
1056 given sampler channel, the plugin path can be overridden at compile
1057 time with ./configure --enable-plugin-dir=/some/dir
1058 - added experimental code for synchronizing instrument editors hosted
1059 in the sampler's process to safely edit instruments while playing
1060 without a crash (hopefully) by either suspending single regions
1061 wherever possible or if unavoidable whole engine(s)
1062 - fixed several issues in fundamental "Thread" class: set scheduling
1063 policy and priority on thread level, set a minimum stack size for
1064 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1065 threads simply inherited properties of starting thread instead of
1066 setting their own policy and priority
1067 - minor fix in our automatic stack trace mechanism on crashes, the
1068 main process did not wait for the stack trace process to finish
1069 its output
1070 - fixed some minor memory leaks
1071 - reenabled assembly features support, at the moment only for
1072 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1073 - minor assembly fix in x86 features detection (don't use the PIC
1074 register, to avoid relocations in the text segment at runtime)
1075 - POSIX callback functions of Thread.h are hidden
1077 * MIDI driver:
1078 - dispatch bank select (MSB and LSB) messages
1080 * audio driver:
1081 - the ALSA audio output driver parameters now reflect the correct
1082 parameter value ranges for the respective selected sound card
1083 (patch by Till Wimmer, a bit fixed and extended)
1085 * Gigasampler format engine:
1086 - if a filter is used and EG2 finishes before EG1, let the voice
1087 die when EG2 has finished (this fixes a problem with clicks and
1088 voice starvation for some gigs)
1089 - playback is no longer disabled during instrument loading
1090 - all notes playing on a channel that changes its instrument keep
1091 playing with the old instrument until they get a note off
1092 command
1093 - EG fix: a release value of zero could cause noises or crash
1094 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1095 - EG fine tuning: when attack is zero the EG starts at a level
1096 above max sustain level, which means that there is a decay phase
1097 even if sustain is 100%
1098 - more EG fixes: the level could sometimes go below zero and cause
1099 noises or crashes
1100 - minor fix of EGDecay (patch by Toshi Nagata)
1101 - fixed compiler error when --enable-override-filter-type was
1102 supplied to the configure script (fixes #46)
1103 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1104 instead of a fix value
1105 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1106 127 (solo mode) only kill voices if the respective mode really
1107 changed
1109 * LSCP server:
1110 - fixed compile time error for old Bison versions
1111 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1112 - parser now supports extended ASCII character set
1113 (up to ASCII code 255, i.e. includes now umlauts and accents)
1114 - filename arguments in LSCP commands now allow to use escape
1115 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1116 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1117 code value like \xf2) (fixes bug #24)
1118 - the following LSCP commands now also support escape sequences for at
1119 least one of their text-based parameters (i.e. name, description):
1126 - returns verbose syntax errors (line and column where syntax error
1127 occured, the unexpected character and the actually expected, possible
1128 character(s), the latter only if less than 5 possibilities)
1129 - made sure that LSCP syntax is not affected by gigedit locale
1130 settings
1131 - bugfix regarding strings parameter lists: all comma separated lists
1132 of strings were treated as being one string containing commas
1133 (fixes #57)
1135 * Bug fixes:
1136 - fixed crash occurring on certain LSCP scripts (Bug 39)
1137 - another thread safety fix for lscp "load engine" and "set
1138 channel audio output device"
1139 - fixed a crash which occurs when reassigning the same engine
1140 on a sampler channel with connected MIDI device
1141 - fixed a crash which occurs when changing the number of ports of a MIDI
1142 device connected to a sampler channel to number less then or equal
1143 to the index of the port to which the sampler channel is connected.
1144 - The previous bindings were not been disconnected when altering
1145 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1146 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1147 - The active stream/voice count statistic was incorrect.
1148 - notification events were not been sent for some sampler
1149 channel changes
1150 - added default min and max values to restrict the number of allowed
1151 audio output channels and MIDI input ports
1152 - the connection to the PCM interface is now closed when destroying
1153 an audio output device
1154 - files with slash in their path or filename could not be loaded
1156 * test cases:
1157 - updated and fixed (haven't been touched in a while)
1159 Version 0.4.0 (24 November 2006)
1161 * packaging changes:
1162 - changed deprecated copyright attribute to license; added ldconfig
1163 to post-(un)install steps; added devel package for liblinuxsampler;
1164 to linuxsampler.spec (RPM)
1165 - install necessary development header files for allowing 3rd party
1166 applications to link against liblinuxsampler
1167 - liblinuxsampler's API documentation can be generated with 'make docs'
1168 (Doxygen required)
1169 - added benchmark to automatically detect the best triangle LFO
1170 implementation (currently either an integer math solution or a
1171 di-harmonic approximation), automatic detection can be overriden
1172 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1173 configure script argument though (mandatory for cross-compilation)
1174 - do not automatically pick optimized gcc flags if the user already
1175 provided some on his own (as CXXFLAGS)
1176 - added compile time option to disable processing of All-Notes-Off MIDI
1177 messages
1178 - added compile time options to allow disabling the various audio and
1179 MIDI drivers
1180 - fixed automatic GCC CPU switch detection on PPC
1181 (patch by Ebrahim Mayat)
1183 * Gigasampler format engine:
1184 - extensive synthesis optimization
1185 (reimplementation of EGs and LFO(s), removed synthesis parameter
1186 prerendering and the synthesis parameter matrix in general, splitting
1187 each audio fragment into subfragments now where each subfragment uses
1188 constant pitch and filter coefficients. The volume coefficient is
1189 linearly interpolated inside a subfragment, unless
1190 --disable-interpolate-volume is set.)
1191 - fine tuning of the EG modulation parameters
1192 - improved filter cutoff calculation by adding support for the
1193 following gig parameters: Cutoff freq (used when no cutoff
1194 controller is defined), Control invert, Minimum cutoff, Velocity
1195 curve and Velocity range. The keyboard tracking now scales
1196 cutoff frequency instead of resonance.
1197 - added support for gig parameter Resonance.
1198 - fixed bug in sysex handling (patch by Juan Linietsky)
1199 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1200 which can be overridden with --enable-global-attenuation
1201 - EG fixes: made the length of "attack hold" stage more
1202 accurate. Release stage can now start before attack stage
1203 ends. Cancel release didn't work when sustain was zero. Attack
1204 time now has a minimal value to prevent clicks.
1205 - fixed pitch changes larger than one octave
1206 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1207 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1208 all modes can be altered via standard GM messages, that is CC5 for
1209 altering portamento time, CC65 for enabling / disabling portamento
1210 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1211 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1212 parameter) and crossfade
1213 - added support for the "attenuation controller threshold" gig
1214 parameter
1215 - added smoothing of volume changes caused by control change
1216 messages
1217 - sample loop parameters are now taken from the DimensionRegion
1218 instead of the wave chunk
1219 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1220 not equal to a power of two
1221 - reimplementation of the filter algorithm. The new filter is more
1222 accurate and supports all gig filter types, including bandreject
1223 and lowpass turbo.
1224 - real support for 24 bit samples - samples are not truncated to
1225 16 bits anymore
1226 - support for aftertouch (channel pressure, not polyphonic
1227 aftertouch)
1228 - LFO1 behaviour fixed (dampening from max volume instead of
1229 amplifying from 0)
1231 * LSCP server:
1232 - fixed application exit on broken pipe error (fixes bug #20)
1233 - fixed the notification messages delay due to lack of
1234 network activity (fixes bug #26)
1235 - fixed parser bug which occured on space(s) within device parameters
1238 * audio driver:
1239 - added aRts audio output driver (by no means RT safe)
1241 * MIDI driver:
1242 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1243 messages several times instead of once
1244 - API extension for MIDI drivers which already supply exact time stamps
1245 for events (i.e. for offline rendering based MIDI drivers)
1246 - added checks for bad MIDI data
1248 * linuxsampler application:
1249 - show available sampler engine types on startup
1251 * general changes:
1252 - support for muting sampler channels and solo mode of the same, two new
1253 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1254 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1255 introduced for this, the behavior is the same like on a mixer console
1256 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1257 --enable-process-muted-channels which can be used to enable the
1258 processing of muted channels.
1259 - support for sostenuto pedal
1260 - support for monitoring the total number of active voices
1263 - fixed some memory management errors
1264 - fixed some concurrency problems that could lead to crashes when
1265 LSCP commands were executed
1266 - fixed crash when instrument loading failed previously on the same
1267 sampler channel (fixes bug #36)
1269 Version 0.3.3 (15 July 2005)
1271 * packaging changes:
1272 - fixed compilation with gcc 4.0
1274 * Gigasampler format engine:
1275 - LFO preprocessing was performed even though the respective LFO was
1276 disabled by the instrument patch (minor efficiency fix)
1277 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1278 for volume ramp downs in the same fragment (needed for current voice
1279 stealing implementation) then simply inform the user with a warning
1280 about possible click sounds and reduce the volume ramp down
1281 appropriately instead of cancelling the audio device connection
1283 Version 0.3.2 (24 June 2005)
1285 * packaging changes:
1286 - updated autotools build files to compile on OS X
1287 (conditional compilation of CoreMIDI and MidiShare drivers)
1288 - hand-crafted assembly optimization code can be disabled with
1289 './configure --disable-asm' (definitely not recommended)
1290 - fixed 'make dist' rule to include all necessary files
1291 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1292 (due to 'dist-bzip2' automake option)
1294 * Gigasampler format engine:
1295 - support for the gig parameters for "release velocity response" curves
1296 - fine tuning of the EGADSR envelope
1297 - volume of release triggered samples now depends on note-on velocity,
1298 note length and gig parameter "release trigger decay" instead of
1299 note-off velocity.
1300 - revised voice stealing
1301 (fixes crash and endless loop caused by voice stealing)
1302 - don't reset scale tuning on instrument or audio output device change
1303 - handle key group conflicts right at the beginning of each fragment
1304 instead of when the respective voice is actually launched
1305 (fixes undefined behavior if stolen voices belonged to a key group -
1306 this case was followed by a "killed voice survived" error message)
1307 - fixed minor issue with null/silence samples
1308 (those stole voices even though they don't need a voice at all which
1309 resulted in "voice stealing didn't work out" messages)
1310 - don't reset volume, pan, pitch and MIDI controller values on
1311 instrument or audio output device change
1313 * LSCP server:
1314 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1315 - fixed LSCP event "CHANNEL_INFO" notification
1316 (e.g. did not notify on volume changes or MIDI program change events)
1318 * linuxsampler application:
1319 - added command line parameters --lscp-addr and --lscp-port to override
1320 default IP address and port of LSCP server
1322 Version 0.3.1 (24 May 2005)
1324 * initial release
