File size: 69348 byte(s)
* Added support for sfz extension opcode 'script' which may be used to
  load real-time instrument script file (NKSP script language).
* Removed code duplication in SFZ file loading code.
* Bumped version (2.0.0.svn37).

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
9 * Gigasampler format engine:
10 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
11 cutoff settings.
12
13 * general changes:
14 - fixed printf type errors (mostly in debug messages)
15 - use unique_ptr instead of auto_ptr when building with C++11
16 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
17 allowing to sort data efficiently in real-time safe manner.
18 - RTList class: added methods for moving/inserting elements to arbitrary
19 position within a list.
20 - RTList class: added method fromPtr() for creating an Iterator object from
21 a raw element pointer.
22 - Attempt to partly fix resetting engine channels vs. resetting engine, an
23 overall cleanup of the Reset*(), ConnectAudioDevice(),
24 DisconnectAudioDevice() API methods would still be desirable though,
25 because the current situation is still inconsistent and error prone.
26 - Active voices are now internally grouped to "Note" objects, instead of
27 being directly assigned to a keyboard key. This allows more fine graded
28 processing of voices, which is i.e. required for certain instrument
29 script features.
30 - Fix: Release trigger voices were not spawned on sustain pedal up
31 (CC #64) events.
32 - Fix: Release trigger voices can now also distinguish correctly between
33 note-off and sustain pedal up events.
34 - All engines: Increased ramp speed of volume smoother and pan smoother
35 (while slow rate of crossfade smoother is preserved) to allow quick
36 volume and pan changes by instrument scripts for instance.
37 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
38 properly and thus were ignored for certain uses.
39 - Added new C++ API method
40 VirtualMidiDevice::SendChannelPressureToSampler().
41 - windows, 32-bit: fixed potential crashes by making sure the stack in
42 sub threads is 16-byte aligned
43 - fixed numerous compiler warnings
44
45 * packaging changes:
46 - removed unnecessary dependency to libuuid
47 (originated by libgig's usage of it)
48 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
49 auto detect whether it (sh/c)ould output its messages in color.
50
51 * Real-time instrument scripts:
52 - Implemented scheduler for delayed MIDI events and for suspended scripts.
53 - Built-in script function "wait()": implemented support for function's
54 "duration-us" argument, thus scripts using this function are now
55 correctly resumed after the requested amount of microseconds.
56 - Built-in script function "play_note()": implemented support for
57 function's "duration-us" argument, thus notes triggered with this
58 argument are now correctly released after the requested amount of
59 microseconds.
60 - Fix: script events were not cleared when engine channel was reset,
61 potentially causing undefined behavior.
62 - Fixed crash which happened when trying to reference an undeclared
63 variable.
64 - Built-in script function "play_note()": Added support for passing
65 special value -1 for "duration-us" argument, which will cause the
66 triggered note to be released once the original note was released.
67 - Instrument script classes now exported with the liblinuxsampler C++ API.
68 - Added new API method ScriptVM::syntaxHighlighting() which provides
69 a convenient syntax highlighting backend for external instrument
70 script editor applications.
71 - Added new C++ API class "ScriptVMFactory".
72 - Extended parser issues to provide not only first line and first
73 column, but also last line and last column of issue (thus marking
74 the precise span of the issue within the source code).
75 - Reload script automatically after being modified by an instrument
76 editor.
77 - NKSP language grammar correction: allow empty event handler bodies
78 like "on note end on".
79 - Implemented built-in script function "change_vol()".
80 - Implemented built-in script function "change_tune()".
81 - Implemented built-in script function "change_pan()".
82 - Implemented built-in script function "change_cutoff()".
83 - Implemented built-in script function "change_reso()".
84 - Implemented built-in script function "event_status()".
85 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
86 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
87 "event_status()" function.
88 - NKSP language: Added support for bitwise operators ".or.", ".and."
89 and ".not.".
90 - NKSP language scanner: Fixed IDs matching to require at least one
91 character (i.e. when matching function names or variable names).
92 - NKSP language scanner: disabled unusued rules.
93 - Fixed behavior of play_note() and note_off() functions which must
94 be distinguished engine internally from "real" MIDI note on/off
95 events in order to avoid misbehaviors like hanging notes.
96 - Implemented built-in script variable "$KSP_TIMER".
97 - Implemented built-in script variable "$NKSP_REAL_TIMER".
98 - Implemented built-in script variable "$NKSP_PERF_TIMER".
99 - Implemented built-in script variable "$ENGINE_UPTIME".
100 - Implemented built-in script function "inc()".
101 - Implemented built-in script function "dec()".
102 - NKSP language fix: division expressions were evaluated too often.
103 - NKSP language fix: string concatenation operator was right
104 associative instead of left (to right).
105 - NKSP language correction: allow empty statements in entire language
106 (i.e. "if end if").
107 - Implemented built-in script function "stop_wait()".
108 - Implemented built-in script variable "$NI_CALLBACK_ID".
109 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
110 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
111 - Added support for read-only built-in variables (respectively
112 handled by the script parser).
113 - Added built-in script constant "$NI_CB_TYPE_INIT".
114 - Added built-in script constant "$NI_CB_TYPE_NOTE".
115 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
116 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
117 - NKSP Language: Added support for user defined script functions.
118 - Implemented built-in script function "change_attack()".
119 - Implemented built-in script function "change_decay()".
120 - Implemented built-in script function "change_release()".
121 - Fixed all change_*() built-in script functions to apply their
122 synthesis parameter changes immediately in case the respective note
123 was triggered at the same time, instead of scheduling the parameter
124 change, especially because it would cause some parameter types's
125 changes either to be ramped (i.e. change_vol()) or other types even
126 to have not effect at all (i.e. change_attack()).
127 - Implemented built-in script function "sh_left()".
128 - Implemented built-in script function "sh_right()".
129 - Implemented built-in script function "min()".
130 - Implemented built-in script function "max()".
131 - NKSP Fix: "init" event handler was not always executed when a script
132 was loaded.
133 - NKSP built-in wait() script function: abort script execution if
134 a negative or zero wait time was passed as argument (since this is
135 a common indication of a bug either of the script or even of the
136 engine, which could lead to RT instability or even worse).
137 - ScriptVM: Implemented automatic suspension of RT safety
138 threatening scripts.
139 - Provide more user friendly error messages on syntax errors.
140 - Fixed NKSP parser warning "Not a statement" when assigning an
141 initializer list to an array variable.
142 - Implemented built-in script array variable "%ALL_EVENTS".
143 - Implemented built-in script function "in_range()".
144
145 * Instruments DB:
146 - Fixed memory access bug of general DB access code which lead to
147 undefined behavior.
148
149 Version 2.0.0 (15 July 2015)

188
189 * general changes:
190 - Refactoring: moved the independent code from
191 the Gigasampler format engine to base classes
192 - command line option '--profile' is currently disabled, since the
193 respective profiling code is currently broken
194 - Introduced support for optional environment variable
195 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
196 where the sampler shall look for instrument editor plugins
197 (patch by Luis Garrido, slightly modified).
198 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
199 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
200 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
201 note (in this implementation of the sampler its simply hard routed to
202 the 1st effect send of the sampler channel, no matter what the actual
203 effect type is)
204 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
205 note (in this implementation of the sampler its simply hard routed to
206 the 2nd effect send of the sampler channel, no matter what the actual
207 effect type is)
208 - implemented support for internal LADSPA effects
209 - raised limit of program change queue from 100 to 512
210 (as suggested by Alex Stone)
211 - implemented sine LFO, pulse LFO and saw LFO
212 - experimental support for per voice equalization
213 - added command line option --exec-after-init
214 - Introduced new C++ API method:
215 EngineChannel::InstrumentFileName(int index)
216 allowing to retrieve the whole list of files used for the loaded
217 instrument on an engine channel (a.k.a. part). Some GigaStudio
218 instruments for example are splitted over several files like
219 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
220 - Added new C++ API method Sampler::GetGlobalMaxVoices().
221 - Added new C++ API method Sampler::GetGlobalMaxStreams().
222 - Added new C++ API method Sampler::SetGlobalMaxVoices().
223 - Added new C++ API method Sampler::SetGlobalMaxStreams().
224 - Various "const" and "restrict" optimizations.
225 - all engines: add pan CC value to instrument pan parameter before
226 applying panning, instead of using two separate pan functions in
227 series (#182)
228 - added a lock guard class for exception safe mutex handling and
229 used it everywhere appropriate
230 - Immediately apply scale tuning changes to active voices.
231 - Exposed scale tuning to C++ API (along to the already existing standard
232 SysEx way).
233 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
234 and broken for ppc64. (Seq_cst loads and stores are actually not
235 used in LS, so the bug wasn't noticable.)
236 - lsatomic.h: added ARMv7 support
237 - Added support for multiple MIDI input ports per sampler channel (and
238 added various new C++ methods for this new feature / design change, old
239 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
240 as deprecated but are still there and should provide full behavior
241 backward compatibility).
242 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
243 unsafe and caused compilation error with clang 2.x).
244 - Bugfix: only process the latest MIDI program change event.
245 - Introducing the LSCP shell, which provides convenient control of the
246 sampler from the command line by providing LSCP aware features.
247 - VirtualMidiDevice: Added support for program change.
248 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
249 - VirtualMidiDevice: Added support for pitch bend.
250 - Aftertouch: extended API to explicitly handle channel pressure and
251 polyphonic key pressure events (so far polyphonic pressure was not
252 supported at all, and channel pressure was rerouted as CC128 but not
253 used so far).
254 - Added initial support for real-time instrument scripts. The script VM
255 code is shared by all sampler engine implemementations, however only the
256 gig file format currently provides support for storing instrument scripts
257 (as LinuxSampler extension to the original GigaStudio 4 format).
258
259 * Gigasampler format engine:
260 - implemented the "round robin keyboard" dimension
261 - fixed round robin and random dimensions for cases when number of
262 dimension zones is not a power of two
263 - made round robin use a counter for each region instead of each
264 key
265 - bugfix: pitch LFO controller "internal+aftertouch" was broken
266 - bugfix: filter keyboard tracking was broken
267 - filter performance fix (an unnecessary copy was made of the
268 filter parameters in each sub fragment)
269 - handle special case when pan parameter in gig file has max or
270 min value
271 - Exclusive Groups: don't ever stop voices of the same note,
272 doesn't sound naturally with a drumkit
273 - fixed EG1 modulation when attack or release is zero
274 - Fixed support for 'aftertouch' attenuation controller.
275 - Fixed crash that happened with velocity split sounds under certain
276 conditions (see also previous commit on libgig).
277 - fixed behaviour of filter LFO
278
279 * SFZ format engine:
280 - Initial implementation (not usable yet)

285 - added support for trigger=first, trigger=legato and sw_previous
286 - allow non-numerical key values ("C#4" for example)
287 - "key" opcode now sets pitch_keycenter too
288 - fixed error when unloading instrument with same sample used by
289 multiple regions
290 - added some opcode aliases, like loopmode for loop_mode, to be
291 more compatible
292 - added support for trigger=release and rt_decay
293 - added support for off_mode=normal
294 - added support for random, seq_position, seq_length and volume

309 - added support for loop_mode=one_shot
310 - fixed playback of 16 bit wav files on big endian CPUs
311 - added support for Ogg Vorbis sample files
312 - use loop markers from sample file if loop_start and loop_end are
313 not set in sfz file
314 - implemeted filters. Filter types: lowpass, bandpass, bandreject
315 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
316 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
317 cutoff_cc, cutoff_chanaft.

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

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

642 channel to a different engine type
643 - fixed crash when deleting a sampler channel or changing engine
644 type while an instrument load was in progress
645 - bugfix: playing a note while changing the instrument could cause
646 a crash, or give "Handing back unknown region" error messages
647 - bugfix: calling SET VOICES (which Fantasia does on start and
648 refresh) could cause instruments to be unloaded
649 - Mac OS X: fixed name collision of enum in EffectControl and
650 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
651 - Mac OS X: fixed hanging threads
652 - Windows: disabled the previous thread fix on non-Mac systems, as
653 it caused hanging threads on Windows
654 - Fixed possible crashes due to corrupted MIDI/audio device list
655 after MIDI/audio device creation failure
656 - When creating MIDI instrument map entries with "PERSISTENT" type, the
657 instruments were uselessly precached with zero samples, however it still
658 took the full preloading time and on 1st program change the respective
659 instrument was completely reloaded again.

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

677 playing a note in a key group
678 - fixed erroneous error message piping in VoiceBase.h
679 (labelled "Disk stream not available in time")
680 - Update effects on sample rate & period size changes (to avoid
681 crashes and noise on such transitions).
682 - ignore missing LADSPA paths without ignoring valid LADSPA paths
683 (fixes #208)
684 - Fixed bug in LSCP grammar definition which caused a statement like
685 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
686 practically irrelevant, however it caused problems with the new LSCP
687 shell's auto completion feature).
688 - Fixed MIDI program change messages being ignored if quickly executed
689 after each other (fixes #231).
690
691 Version 1.0.0 (31 July 2009)
692
693 * packaging changes:
694 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
695 causing e.g. the libgig test to fail when
696 "./configure --disable-jack-driver" was used
697 (patch by Alexis Ballier)
698 - fixed compilation with gcc 4.3
699 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

704 - minor fix in configure for mmsystem.h detection on MinGW
705 - Windows: look for editor plugins and Fantasia using base
706 directory of liblinuxsampler dll (look in the same directory and one
707 directory above)
708 - configure script fix: removed unconditional use of SSE
709 - fixed building with sqlite installed in a non-standard directory
710 - when cross-compiling, don't try to create instruments.db
711 - fix for new mingw-w64 version, which has usleep
712
713 * general changes:
714 - bugfix: on some POSIX systems instrument editor plugins refused to
715 load as we used a non-portable Linux specific struct field
716 (fixes bug #70, patch by Ronald Baljeu)
717 - fixed endless loop which occured when loading an instrument editor
718 plugin DLL on Windows systems failed
719 - fixed memory leaks that occurred when liblinuxsampler was unloaded
720 - optimized the SynchronizedConfig class so it doesn't wait
721 unnecessarily long after an update
722 - added support for notifying instrument editors on note-on / note-off
723 events (e.g. to highlight the pressed keys on the virtual keyboard
724 of gigedit)
725 - added support for triggering notes by instrument editors (see above)
726 - be verbose on DLL load errors (on Linux)
727 - fixed di-harmonic triangle LFO implementation (this LFO implementation
728 is only used by very few systems, most pick the int math
729 implementation, which is usually faster)
730 - fixes for audio drivers with varying buffer sizes
731 - experimental support for running LinuxSampler as a DSSI, LV2 and
732 VST plugin
733 - notification events for stream/voice count statistics are now sent
734 only when there are actual changes
735 - added memory ordering constraints to improve stability on
736 multi-core and multi-cpu systems
737 - maximum voices and disk streams can now be altered at runtime
738 - fixed CPU feature detection on x86_64 (maybe fixes #108)
739 - automatic stacktrace mechanism is now turned off by default and can
740 be switched on by command line option "--stacktrace" (the automatic
741 stacktrace mechanism seems to be broken on most systems at the moment)
742 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
743 a pointer to the launched InstrumentEditor object
744 - added optional 3rd party user data parameter for following
745 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
746 InstrumentEditor::Launch(),
747 InstrumentManager::LaunchInstrumentEditor()
748 - theoretical fix: made SynchronizedConfig follow C++0x memory
749 model more strictly
750 - fixes for using large audio device buffers
751 - Windows: add the installation directory to the DLL search path
752 when loading an editor plugin (solves problems with VST and
753 gigedit on systems with other GTK versions installed)
754 - updated linuxsampler man page
755
756 * audio driver:
757 - removed the nonsense audio channel constraint (which was hard coded to
758 max. 100 audio channels) for most audio drivers
759 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
760 opposed to the LSCP specs
761 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
762 reflected the wrong value
763 - fixed a memory management bug in ASIO driver
764 - Makefile fix: JACK_CFLAGS wasn't used
765 - JACK: use jack_client_open instead of the deprecated
766 jack_client_new

772 win64)
773 - VST: added support for sample rate and buffer size changes
774 - VST: close editor (Fantasia) when the VST is removed
775 - VST: avoid opening Fantasia more than once for each VST instance
776 - VST: export main function as "main" on Linux too (fix for
777 energyXT)
778 - VST: changed number of output channels from one stereo to 16
779 stereo
780 - added channel routing, fxsends and midi maps to the settings
781 stored in the plugin state
782 - performance optimization of AudioChannel::MixTo() and
783 AudioChannel::CopyTo() methods using GCC vector exensions
784 (if available)
785 - ASIO fixes: avoid initializing the device twice, avoid throwing
786 exception when getting parameters from a disconnected device
787
788 * MIDI driver:
789 - added JACK MIDI driver
790 - dispatch bank select as ordinary CC as well, the user might seriously
791 want to (mis)use it for some purpose ("fixed" in all current MIDI
792 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
793 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
794 CoreMidi or AU
795 - fixed mingw-w64 compilation error in MME driver
796 - made program change handling in MIDI thread real-time safe by
797 moving the logic to a non-RT thread
798 - fixed minor memory leak in ALSA driver
799
800 * instruments database:
801 - avoid time consuming samples scanning when adding instruments
802 to the instruments database

807 - work-around for missing fnmatch function on Windows to make
808 instrument database compilable
809 - added instrument database support on Windows
810 works with both standalone mode and VST plugin.
811 the instruments DB file is located in
812 %USERPROFILE%\.linuxsampler\instruments.db which allows different
813 databases for each windows user
814 if no DB is present it automatically creates the .linuxsampler subdir
815 and then creates an empty DB
816 - fixed recursive import, which was broken on Windows
817
818 * Gigasampler format engine:
819 - fixed a memory leak that could happen when a channel was deleted
820 while notes were playing
821 - made it possible to load an instrument even if the audio thread
822 isn't running
823 - added partial support for the "Controller Triggered" MIDI rule,
824 enough for piano gigs with pedal noise samples
825 - minor fix: only mark FX sends as being modified if really the
826 respective FX send MIDI controller was used
827 - added support for GM global device volume SysEx message
828 (can be selected at compile time to either apply globally to the
829 whole sampler [default] or only to the sampler channels that are
830 connected to the respective MIDI input port the SysEx message arrived
831 on)
832 - bugfix: notes triggered at position 0 in the audio buffer were
833 sometimes wrongly killed in the same buffer, causing no sound to
834 be played
835 - added support for chromatic / drumkit mode Roland GS Sysex message
836 which is usally used to switch a part between chromatic sounds and
837 drumkit sounds (as opposed to their common default setting of MIDI
838 part 10 being a drumkit part and all other ones chromatic parts), in
839 LS however one can switch between the first 16 MIDI instrument maps
840 defined for the sampler
841 - made it possible to create multiple sample channels even if the
842 audio thread isn't running
843 - fixed crash when removing channel with active voices (#116)
844 - bugfix: on sample reference changes (instrument editor), only
845 un-cache the respective sample if it's really not used by any
846 sampler engine anymore
847 - re-cache samples in case they were changed by an instrument editor,
848 e.g. when a sample was added while playing (#82)
849 - fixed hanging notes which occured when note-off event had the exact
850 same time stamp as the voice's note-on event and occured both in the
851 same audio fragment cycle (fixes bug #112)
852 - added support for the "fine tune" and "pitch bend range"
853 instrument-level gig parameters
854 - fixed minor artifacts in pitch bend handling
855 - added support for GS Reset SysEx message
856 - allow gig files to use unlimited downward pitch shifting
857 - added a limit check for upward pitch shifting
858 - bugfix: sometimes, when playing a note twice fast, the second
859 note was silent
860 - fixed crash happening when a pitch bend event arrived at the
861 same time a new instrument was loading
862
863 * LSCP server:
864 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
865 react on MIDI data arriving on certain sampler channels (so far only
866 Note-On and Note-Off events are sent via this LSCP event)
867 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
868 react on MIDI data arriving on certain MIDI input devices (so far only
869 Note-On and Note-Off events are sent via this LSCP event)
870 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
871 SET DB_INSTRUMENT FILE_PATH
872 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
873 frontends to send MIDI messages to specific sampler channel
874 - added two additional fields to GET FILE INSTRUMENT INFO command -
875 KEY_BINDINGS and KEYSWITCH_BINDINGS
876 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
877 was incorrect
878 - Optimized the retrieval of the MIDI instrument mappings
879 - added new LSCP command "SET VOICES" to globally alter the maximum
880 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
881 be triggered respectively
882 - added new LSCP command "SET STREAMS" to globally alter the maximum
883 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
884 which will be triggered respectively
885 - bugfix: retry if "select" returns EINTR (this fixes a crash when
886 a gigedit file dialog is opened)
887 - close all connections when LSCPServer is deleted
888 - hard close of all sockets on exit
889 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
890 driver
891
892 * Bug fixes:
893 - fixed a crash which occurs when removing a sampler channel waiting
894 to start instrument loading after another channel
895 - fixed a crash which occurs when removing a sampler channel with
896 instrument loading in progress (bug #113)
897 - fixed termination caused by uncaught exception when adding MIDI
898 instrument with PERSISTENT load mode
899 - fixed possible iterator invalidations when resetting the sampler
900 - fixed memory leaks when issuing the following LSCP commands:
901 GET AUDIO_OUTPUT_DRIVER INFO
902 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
903 GET MIDI_INPUT_DRIVER INFO
904 GET MIDI_INPUT_DRIVER_PARAMETER INFO
905 - fixed possible compilation error when sqlite is not present
906 - fixed orphaned pointers when setting maximum voices limit (bug #118)
907 - fixed crash when changing the audio output device of a sampler
908 channel with loaded instrument and start playing notes
909 - fixed endless loop in Engine::SuspendAll() (bug #120)
910 - fixed a low-level atomic load function that was broken on 64-bit
911 PowerPC, which probably could cause crashes on that platform
912 - fixed a memory management error which could cause a crash when a
913 plugin was unloaded
914 - bugfix: two private structs had the same name, which could cause
915 problems if the linker chose the wrong constructor
916 - fixed low-level ConditionServer usage bug that caused lockups on
917 Windows
918
919
920 Version 0.5.1 (6 December 2007)
921
922 * packaging changes:
923 - added autoconf checks for pthread library
924 - added autoconf check for pthread bug found on certain NPTL-enabled
925 glibc versions (see Gentoo bug report #194076)
926 - added autoconf checks for MS Windows
927
928 * general changes:
929 - bugfix: the thread used by an editor plugin didn't die when the
930 editor closed
931 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
932 out all the space. operator--() did not apply size_mask after
933 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
934 order to avoid problems with the _NonVolatileReader functions.
935 - bugfix: Stream.h: added a missing divide by BytesPerSample in
936 GetWriteSpace(). Since this function is currently only used in
937 the stream's qsort() compare function, it didn't trigger any
938 bugs.
939 - Resampler.h, Synthesizer.h: cubic interpolation now works in
940 24bit mode too. Faster method to read 24bit words on little
941 endian machines (x86): replaced 3 byte reads + shifts with a 1
942 unaligned 32bit read and shift
943 - experimental support for MS Windows (MIDI input via MME, AUDIO
944 output via ASIO)
945 - made handling of SIGINT signal (Ctrl-C) a bit more robust
946 - support for monitoring the total number of active disk streams
947 (new LSCP commands: GET TOTAL_STREAM_COUNT,
948 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
949
950 * AUDIO driver:
951 - added Windows ASIO low latency audio driver
952
953 * MIDI driver:
954 - added MME Windows MIDI driver
955
956 * LSCP server:
957 - added support for Windows style path / filenames, however with
958 forward slash path separators instead of backslash
959 (i.e. "C:/foo/bar.gig")
960 - allow naughty liblscp to send non-string device parameters within
961 apostrophes as well
962 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
963 "LIST FILE INSTRUMENTS <file>" and
964 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
965 about an arbitrary instrument file on the system where the sampler is
966 running on
967
968 Version 0.5.0 (15 October 2007)
969
970 * packaging changes:
971 - config.h is not going to be installed along with liblinuxsampler's
972 API header files anymore
973 - only the API relevant header (and source) files will be exported to
974 the Doxygen API documentation (explicitly listed in Doxyfile.in)
975 - added completely new XCode project files for Mac OSX which is now
976 capable to execute our autoconf environment, thus no need anymore
977 to maintain the compile time configuration file (osx/version.h) for
978 OSX manually (patch by Toshi Nagata)
979 - fixed buggy boolean --enable-foo / --disable-foo configure script
980 parameters
981 - global.h now only covers global definitions that are needed for the
982 C++ API header files, all implementation internal global definitions
983 are now in global_private.h
984 - atomic.h is not exposed to the C++ API anymore
985 - no need to include config.h anymore for using LS's API header files
986 - fixed warnings in API doc generation
987
988 * general changes:
989 - replaced the old, confusing MIDI program change mechanism by a
990 flexible MIDI instrument mapper which allows to map arbitrary
991 (MIDI bank, MIDI program) pairs with arbitrary
992 (engine type, instrument file, file index) triplets which will be
993 loaded on the respective channel when such MIDI program change
994 messages arrive, beside that, each entry allows to define a life-time
995 strategy for the instrument, so the user can define whether the
996 instrument should i.e. be permanently loaded (to be able to switch
997 quickly among sounds) or i.e. loaded just on demand when the
998 respective program change arrives (to safe RAM space), as well as a
999 global volume factor for each entry, so the user can adjust the volume
1000 dynamic of his mapped instrument collection without having to modify
1001 the instrument files, also one can manage arbitrary amount of such
1002 MIDI instrument maps and assign each sampler channel individually
1003 a certain map, so that i.e. separation of normal instruments and
1004 drumkits is possible
1005 - new notification events for tracking changes to audio/MIDI devices,
1006 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1007 - sampler was limited to load max. 200 instruments in the background
1008 due to a constant size RingBuffer FIFO which is now replaced by a
1009 dynamic (unlimited) size std::list FIFO
1010 - added FX sends, these allow to route audio signals to arbitrary audio
1011 output channels for being processed by external effect processors
1012 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1013 controllers
1014 - global (sampler wide) volume can now be controlled at runtime
1015 - Implemented new, improved notification system
1016 - fixed compilation errors regarding OSX
1017 (patch by Toshi Nagata)
1018 - implemented instruments database
1019 - added support for escape sequences to the instruments database
1020 - added highly experimental support for on-the-fly instrument editing
1021 within the sampler's process (by using instrument editor plugins),
1022 you'll notice the new "Registered instrument editors:" message on
1023 startup, added a new LSCP command:
1024 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1025 to spawn a matching instrument editor for the instrument on the
1026 given sampler channel, the plugin path can be overridden at compile
1027 time with ./configure --enable-plugin-dir=/some/dir
1028 - added experimental code for synchronizing instrument editors hosted
1029 in the sampler's process to safely edit instruments while playing
1030 without a crash (hopefully) by either suspending single regions
1031 wherever possible or if unavoidable whole engine(s)
1032 - fixed several issues in fundamental "Thread" class: set scheduling
1033 policy and priority on thread level, set a minimum stack size for
1034 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1035 threads simply inherited properties of starting thread instead of
1036 setting their own policy and priority
1037 - minor fix in our automatic stack trace mechanism on crashes, the
1038 main process did not wait for the stack trace process to finish
1039 its output
1040 - fixed some minor memory leaks
1041 - reenabled assembly features support, at the moment only for
1042 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1043 - minor assembly fix in x86 features detection (don't use the PIC
1044 register, to avoid relocations in the text segment at runtime)
1045 - POSIX callback functions of Thread.h are hidden
1046
1047 * MIDI driver:
1048 - dispatch bank select (MSB and LSB) messages
1049
1050 * audio driver:
1051 - the ALSA audio output driver parameters now reflect the correct
1052 parameter value ranges for the respective selected sound card
1053 (patch by Till Wimmer, a bit fixed and extended)
1054
1055 * Gigasampler format engine:
1056 - if a filter is used and EG2 finishes before EG1, let the voice
1057 die when EG2 has finished (this fixes a problem with clicks and
1058 voice starvation for some gigs)
1059 - playback is no longer disabled during instrument loading
1060 - all notes playing on a channel that changes its instrument keep
1061 playing with the old instrument until they get a note off
1062 command
1063 - EG fix: a release value of zero could cause noises or crash
1064 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1065 - EG fine tuning: when attack is zero the EG starts at a level
1066 above max sustain level, which means that there is a decay phase
1067 even if sustain is 100%
1068 - more EG fixes: the level could sometimes go below zero and cause
1069 noises or crashes
1070 - minor fix of EGDecay (patch by Toshi Nagata)
1071 - fixed compiler error when --enable-override-filter-type was
1072 supplied to the configure script (fixes #46)
1073 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1074 instead of a fix value
1075 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1076 127 (solo mode) only kill voices if the respective mode really
1077 changed
1078
1079 * LSCP server:
1080 - fixed compile time error for old Bison versions
1081 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1082 - parser now supports extended ASCII character set
1083 (up to ASCII code 255, i.e. includes now umlauts and accents)
1084 - filename arguments in LSCP commands now allow to use escape
1085 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1086 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1087 code value like \xf2) (fixes bug #24)
1088 - the following LSCP commands now also support escape sequences for at
1089 least one of their text-based parameters (i.e. name, description):
1090 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1091 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1092 "SET DB_INSTRUMENT_DIRECTORY NAME",
1093 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1094 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1095 "FIND DB_INSTRUMENT_DIRECTORIES"
1096 - returns verbose syntax errors (line and column where syntax error
1097 occured, the unexpected character and the actually expected, possible
1098 character(s), the latter only if less than 5 possibilities)
1099 - made sure that LSCP syntax is not affected by gigedit locale
1100 settings
1101 - bugfix regarding strings parameter lists: all comma separated lists
1102 of strings were treated as being one string containing commas
1103 (fixes #57)
1104
1105 * Bug fixes:
1106 - fixed crash occurring on certain LSCP scripts (Bug 39)
1107 - another thread safety fix for lscp "load engine" and "set
1108 channel audio output device"
1109 - fixed a crash which occurs when reassigning the same engine
1110 on a sampler channel with connected MIDI device
1111 - fixed a crash which occurs when changing the number of ports of a MIDI
1112 device connected to a sampler channel to number less then or equal
1113 to the index of the port to which the sampler channel is connected.
1114 - The previous bindings were not been disconnected when altering
1115 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1116 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1117 - The active stream/voice count statistic was incorrect.
1118 - notification events were not been sent for some sampler
1119 channel changes
1120 - added default min and max values to restrict the number of allowed
1121 audio output channels and MIDI input ports
1122 - the connection to the PCM interface is now closed when destroying
1123 an audio output device
1124 - files with slash in their path or filename could not be loaded
1125
1126 * test cases:
1127 - updated and fixed (haven't been touched in a while)
1128
1129 Version 0.4.0 (24 November 2006)
1130
1131 * packaging changes:
1132 - changed deprecated copyright attribute to license; added ldconfig
1133 to post-(un)install steps; added devel package for liblinuxsampler;
1134 to linuxsampler.spec (RPM)
1135 - install necessary development header files for allowing 3rd party
1136 applications to link against liblinuxsampler
1137 - liblinuxsampler's API documentation can be generated with 'make docs'
1138 (Doxygen required)
1139 - added benchmark to automatically detect the best triangle LFO
1140 implementation (currently either an integer math solution or a
1141 di-harmonic approximation), automatic detection can be overriden
1142 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1143 configure script argument though (mandatory for cross-compilation)
1144 - do not automatically pick optimized gcc flags if the user already
1145 provided some on his own (as CXXFLAGS)
1146 - added compile time option to disable processing of All-Notes-Off MIDI
1147 messages
1148 - added compile time options to allow disabling the various audio and
1149 MIDI drivers
1150 - fixed automatic GCC CPU switch detection on PPC
1151 (patch by Ebrahim Mayat)
1152
1153 * Gigasampler format engine:
1154 - extensive synthesis optimization
1155 (reimplementation of EGs and LFO(s), removed synthesis parameter
1156 prerendering and the synthesis parameter matrix in general, splitting
1157 each audio fragment into subfragments now where each subfragment uses
1158 constant pitch and filter coefficients. The volume coefficient is
1159 linearly interpolated inside a subfragment, unless
1160 --disable-interpolate-volume is set.)
1161 - fine tuning of the EG modulation parameters
1162 - improved filter cutoff calculation by adding support for the
1163 following gig parameters: Cutoff freq (used when no cutoff
1164 controller is defined), Control invert, Minimum cutoff, Velocity
1165 curve and Velocity range. The keyboard tracking now scales
1166 cutoff frequency instead of resonance.
1167 - added support for gig parameter Resonance.
1168 - fixed bug in sysex handling (patch by Juan Linietsky)
1169 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1170 which can be overridden with --enable-global-attenuation
1171 - EG fixes: made the length of "attack hold" stage more
1172 accurate. Release stage can now start before attack stage
1173 ends. Cancel release didn't work when sustain was zero. Attack
1174 time now has a minimal value to prevent clicks.
1175 - fixed pitch changes larger than one octave
1176 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1177 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1178 all modes can be altered via standard GM messages, that is CC5 for
1179 altering portamento time, CC65 for enabling / disabling portamento
1180 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1181 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1182 parameter) and crossfade
1183 - added support for the "attenuation controller threshold" gig
1184 parameter
1185 - added smoothing of volume changes caused by control change
1186 messages
1187 - sample loop parameters are now taken from the DimensionRegion
1188 instead of the wave chunk
1189 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1190 not equal to a power of two
1191 - reimplementation of the filter algorithm. The new filter is more
1192 accurate and supports all gig filter types, including bandreject
1193 and lowpass turbo.
1194 - real support for 24 bit samples - samples are not truncated to
1195 16 bits anymore
1196 - support for aftertouch (channel pressure, not polyphonic
1197 aftertouch)
1198 - LFO1 behaviour fixed (dampening from max volume instead of
1199 amplifying from 0)
1200
1201 * LSCP server:
1202 - fixed application exit on broken pipe error (fixes bug #20)
1203 - fixed the notification messages delay due to lack of
1204 network activity (fixes bug #26)
1205 - fixed parser bug which occured on space(s) within device parameters
1206 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1207
1208 * audio driver:
1209 - added aRts audio output driver (by no means RT safe)
1210
1211 * MIDI driver:
1212 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1213 messages several times instead of once
1214 - API extension for MIDI drivers which already supply exact time stamps
1215 for events (i.e. for offline rendering based MIDI drivers)
1216 - added checks for bad MIDI data
1217
1218 * linuxsampler application:
1219 - show available sampler engine types on startup
1220
1221 * general changes:
1222 - support for muting sampler channels and solo mode of the same, two new
1223 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1224 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1225 introduced for this, the behavior is the same like on a mixer console
1226 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1227 --enable-process-muted-channels which can be used to enable the
1228 processing of muted channels.
1229 - support for sostenuto pedal
1230 - support for monitoring the total number of active voices
1231 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1232 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1233 - fixed some memory management errors
1234 - fixed some concurrency problems that could lead to crashes when
1235 LSCP commands were executed
1236 - fixed crash when instrument loading failed previously on the same
1237 sampler channel (fixes bug #36)
1238
1239 Version 0.3.3 (15 July 2005)
1240
1241 * packaging changes:
1242 - fixed compilation with gcc 4.0
1243
1244 * Gigasampler format engine:
1245 - LFO preprocessing was performed even though the respective LFO was
1246 disabled by the instrument patch (minor efficiency fix)
1247 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1248 for volume ramp downs in the same fragment (needed for current voice
1249 stealing implementation) then simply inform the user with a warning
1250 about possible click sounds and reduce the volume ramp down
1251 appropriately instead of cancelling the audio device connection
1252
1253 Version 0.3.2 (24 June 2005)
1254
1255 * packaging changes:
1256 - updated autotools build files to compile on OS X
1257 (conditional compilation of CoreMIDI and MidiShare drivers)
1258 - hand-crafted assembly optimization code can be disabled with
1259 './configure --disable-asm' (definitely not recommended)
1260 - fixed 'make dist' rule to include all necessary files
1261 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1262 (due to 'dist-bzip2' automake option)
1263
1264 * Gigasampler format engine:
1265 - support for the gig parameters for "release velocity response" curves
1266 - fine tuning of the EGADSR envelope
1267 - volume of release triggered samples now depends on note-on velocity,
1268 note length and gig parameter "release trigger decay" instead of
1269 note-off velocity.
1270 - revised voice stealing
1271 (fixes crash and endless loop caused by voice stealing)
1272 - don't reset scale tuning on instrument or audio output device change
1273 - handle key group conflicts right at the beginning of each fragment
1274 instead of when the respective voice is actually launched
1275 (fixes undefined behavior if stolen voices belonged to a key group -
1276 this case was followed by a "killed voice survived" error message)
1277 - fixed minor issue with null/silence samples
1278 (those stole voices even though they don't need a voice at all which
1279 resulted in "voice stealing didn't work out" messages)
1280 - don't reset volume, pan, pitch and MIDI controller values on
1281 instrument or audio output device change
1282
1283 * LSCP server:
1284 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1285 - fixed LSCP event "CHANNEL_INFO" notification
1286 (e.g. did not notify on volume changes or MIDI program change events)
1287
1288 * linuxsampler application:
1289 - added command line parameters --lscp-addr and --lscp-port to override
1290 default IP address and port of LSCP server
1291
1292 Version 0.3.1 (24 May 2005)
1293
1294 * initial release
