Revision 2947 - (show annotations) (download)
Thu Jul 14 10:37:28 2016 UTC (3 years, 4 months ago) by schoenebeck
File size: 65939 byte(s)
* NKSP language correction: allow empty statements in entire language
  (i.e. "if end if").
* Bumped version (2.0.0.svn16).

1 Version SVN trunk (?)
2
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
5
6 * general changes:
7 - fixed printf type errors (mostly in debug messages)
8 - use unique_ptr instead of auto_ptr when building with C++11
9 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10 allowing to sort data efficiently in real-time safe manner.
11 - RTList class: added methods for moving/inserting elements to arbitrary
12 position within a list.
13 - RTList class: added method fromPtr() for creating an Iterator object from
14 a raw element pointer.
15 - Attempt to partly fix resetting engine channels vs. resetting engine, an
16 overall cleanup of the Reset*(), ConnectAudioDevice(),
17 DisconnectAudioDevice() API methods would still be desirable though,
18 because the current situation is still inconsistent and error prone.
19 - Active voices are now internally grouped to "Note" objects, instead of
20 being directly assigned to a keyboard key. This allows more fine graded
21 processing of voices, which is i.e. required for certain instrument
22 script features.
23 - Fix: Release trigger voices were not spawned on sustain pedal up
24 (CC #64) events.
25 - Fix: Release trigger voices can now also distinguish correctly between
26 note-off and sustain pedal up events.
27
28 * packaging changes:
29 - removed unnecessary dependency to libuuid
30 (originated by libgig's usage of it)
31 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32 auto detect whether it (sh/c)ould output its messages in color.
33
34 * Real-time instrument scripts:
35 - Implemented scheduler for delayed MIDI events and for suspended scripts.
36 - Built-in script function "wait()": implemented support for function's
37 "duration-us" argument, thus scripts using this function are now
38 correctly resumed after the requested amount of microseconds.
39 - Built-in script function "play_note()": implemented support for
40 function's "duration-us" argument, thus notes triggered with this
41 argument are now correctly released after the requested amount of
42 microseconds.
43 - Fix: script events were not cleared when engine channel was reset,
44 potentially causing undefined behavior.
45 - Fixed crash which happened when trying to reference an undeclared
46 variable.
47 - Built-in script function "play_note()": Added support for passing
48 special value -1 for "duration-us" argument, which will cause the
49 triggered note to be released once the original note was released.
50 - Instrument script classes now exported with the liblinuxsampler C++ API.
51 - Added new API method ScriptVM::syntaxHighlighting() which provides
52 a convenient syntax highlighting backend for external instrument
53 script editor applications.
54 - Added new C++ API class "ScriptVMFactory".
55 - Extended parser issues to provide not only first line and first
56 column, but also last line and last column of issue (thus marking
57 the precise span of the issue within the source code).
58 - Reload script automatically after being modified by an instrument
59 editor.
60 - NKSP language grammar correction: allow empty event handler bodies
61 like "on note end on".
62 - Implemented built-in script function "change_vol()".
63 - Implemented built-in script function "change_tune()".
64 - Implemented built-in script function "change_pan()".
65 - Implemented built-in script function "change_cutoff()".
66 - Implemented built-in script function "change_reso()".
67 - Implemented built-in script function "event_status()".
68 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70 "event_status()" function.
71 - NKSP language: Added support for bitwise operators ".or.", ".and."
72 and ".not.".
73 - NKSP language scanner: Fixed IDs matching to require at least one
74 character (i.e. when matching function names or variable names).
75 - NKSP language scanner: disabled unusued rules.
76 - Fixed behavior of play_note() and note_off() functions which must
77 be distinguished engine internally from "real" MIDI note on/off
78 events in order to avoid misbehaviors like hanging notes.
79 - Implemented built-in script variable "$KSP_TIMER".
80 - Implemented built-in script variable "$NKSP_REAL_TIMER".
81 - Implemented built-in script variable "$NKSP_PERF_TIMER".
82 - Implemented built-in script variable "$ENGINE_UPTIME".
83 - Implemented built-in script function "inc()".
84 - Implemented built-in script function "dec()".
85 - NKSP language fix: division expressions were evaluated too often.
86 - NKSP language fix: string concatenation operator was right
87 associative instead of left (to right).
88 - NKSP language correction: allow empty statements in entire language
89 (i.e. "if end if").
90
91 Version 2.0.0 (15 July 2015)
92

127 - enabled automake 'subdir-objects' option and moved external
128 source references (vst, au, asio) from makefiles to cpp files,
129 in order to get rid of warnings from automake 1.14
130
131 * general changes:
132 - Refactoring: moved the independent code from
133 the Gigasampler format engine to base classes
134 - command line option '--profile' is currently disabled, since the
135 respective profiling code is currently broken
136 - Introduced support for optional environment variable
137 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
138 where the sampler shall look for instrument editor plugins
139 (patch by Luis Garrido, slightly modified).
140 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
141 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
142 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
143 note (in this implementation of the sampler its simply hard routed to
144 the 1st effect send of the sampler channel, no matter what the actual
145 effect type is)
146 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
147 note (in this implementation of the sampler its simply hard routed to
148 the 2nd effect send of the sampler channel, no matter what the actual
149 effect type is)
150 - implemented support for internal LADSPA effects
151 - raised limit of program change queue from 100 to 512
152 (as suggested by Alex Stone)
153 - implemented sine LFO, pulse LFO and saw LFO
154 - experimental support for per voice equalization
155 - added command line option --exec-after-init
156 - Introduced new C++ API method:
157 EngineChannel::InstrumentFileName(int index)
158 allowing to retrieve the whole list of files used for the loaded
159 instrument on an engine channel (a.k.a. part). Some GigaStudio
160 instruments for example are splitted over several files like
161 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
162 - Added new C++ API method Sampler::GetGlobalMaxVoices().
163 - Added new C++ API method Sampler::GetGlobalMaxStreams().
164 - Added new C++ API method Sampler::SetGlobalMaxVoices().
165 - Added new C++ API method Sampler::SetGlobalMaxStreams().
166 - Various "const" and "restrict" optimizations.
167 - all engines: add pan CC value to instrument pan parameter before
168 applying panning, instead of using two separate pan functions in
169 series (#182)
170 - added a lock guard class for exception safe mutex handling and
171 used it everywhere appropriate
172 - Immediately apply scale tuning changes to active voices.
173 - Exposed scale tuning to C++ API (along to the already existing standard
174 SysEx way).
175 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
176 and broken for ppc64. (Seq_cst loads and stores are actually not
177 used in LS, so the bug wasn't noticable.)
178 - lsatomic.h: added ARMv7 support
179 - Added support for multiple MIDI input ports per sampler channel (and
180 added various new C++ methods for this new feature / design change, old
181 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
182 as deprecated but are still there and should provide full behavior
183 backward compatibility).
184 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
185 unsafe and caused compilation error with clang 2.x).
186 - Bugfix: only process the latest MIDI program change event.
187 - Introducing the LSCP shell, which provides convenient control of the
188 sampler from the command line by providing LSCP aware features.
189 - VirtualMidiDevice: Added support for program change.
190 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
191 - VirtualMidiDevice: Added support for pitch bend.
192 - Aftertouch: extended API to explicitly handle channel pressure and
193 polyphonic key pressure events (so far polyphonic pressure was not
194 supported at all, and channel pressure was rerouted as CC128 but not
195 used so far).
196 - Added initial support for real-time instrument scripts. The script VM
197 code is shared by all sampler engine implemementations, however only the
198 gig file format currently provides support for storing instrument scripts
199 (as LinuxSampler extension to the original GigaStudio 4 format).
200

206 key
207 - bugfix: pitch LFO controller "internal+aftertouch" was broken
208 - bugfix: filter keyboard tracking was broken
209 - filter performance fix (an unnecessary copy was made of the
210 filter parameters in each sub fragment)
211 - handle special case when pan parameter in gig file has max or
212 min value
213 - Exclusive Groups: don't ever stop voices of the same note,
214 doesn't sound naturally with a drumkit
215 - fixed EG1 modulation when attack or release is zero

383 - bugfix: line numbers in error messages were wrong after "#include"
384 - added support for float and 32 bit sample files
385
386 * SoundFont format engine:
387 - Initial implementation (not usable yet)
388 - RT-safeness: avoid malloc in audio thread

396 - AU bugfix: failed to destroy its audio/MIDI devices
397 - Listen to all interfaces on Mac OS X (INADDR_ANY)
398 - VST bugfix: If the host called resume() before and after

402 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
403 64 bit Windows
404 - AU: changed number of output channels from one stereo to 16
405 stereo
406 - VST: made it possible to build the VST plugin for Mac
407 - AU: link AU plugin dynamically if --disable-shared isn't
408 specified

410 - VST bugfix: instrument loading hang and crashed the host when
411 the plugin was loaded a second time (#174)
412 - plugin bugfix: instrument loading hang when the plugin was
413 loaded a second time (this time it's for Linux and Mac, previous
414 similar fix was for Windows)
415 - thread safety fixes for the instrument loading thread
416 - LV2: use the new lv2 package if present

434 informations like the EngineChannel for which the instrument editor was
435 spawned for. This allows the instrument editors to interact more actively
436 with the sampler.
437
438 * MIDI driver:
439 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
440 the ALSA sequencer client name

442 there is no reason for this limit
443 - MME: fixed memory handling bug found with cppcheck
444 - MME: removed compiler warning
445 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
446 which allows to retrieve the list of CoreMIDI clients / ports and to connect
447 to them a la JACK, via the usual sampler APIs
448 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
449 the driver will automatically connect to other CoreMIDI clients' ports
450 (e.g. external MIDI devices being attached to the Mac)
451 - added support for MIDI note on velocity filter
452 - CoreMIDI: fixed memory deallocation error
453 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
454 virtual keyboards in frontends / instrument editors being stuck.

516 - Added support for auto correction of obvious and trivial syntax mistakes.
517 - Added support for auto completion by tab key.
518 - Show currently available auto completion while typing.
519 - Added support for browsing command history with up / down keys.

523 - Added support for moving cursor left/right with arrow keys.
524 - Added support for built-in LSCP reference documentation, which will
525 automatically show the relevant LSCP reference section on screen as soon

575 - Pass/preserve polyphonic variable data from respective "note" event
576 handler to "release" event handler.
577
578 * Bug fixes:

582 channel to a different engine type
583 - fixed crash when deleting a sampler channel or changing engine
584 type while an instrument load was in progress
585 - bugfix: playing a note while changing the instrument could cause
586 a crash, or give "Handing back unknown region" error messages
587 - bugfix: calling SET VOICES (which Fantasia does on start and
588 refresh) could cause instruments to be unloaded
589 - Mac OS X: fixed name collision of enum in EffectControl and
590 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
591 - Mac OS X: fixed hanging threads
592 - Windows: disabled the previous thread fix on non-Mac systems, as
593 it caused hanging threads on Windows
594 - Fixed possible crashes due to corrupted MIDI/audio device list
595 after MIDI/audio device creation failure
596 - When creating MIDI instrument map entries with "PERSISTENT" type, the
597 instruments were uselessly precached with zero samples, however it still
598 took the full preloading time and on 1st program change the respective
599 instrument was completely reloaded again.
600 - fixed handling of rapid bank select and program change messages
601 sent to the same sampler channel (patch from the Open Octave
602 project, slightly adjusted)

617 playing a note in a key group
618 - fixed erroneous error message piping in VoiceBase.h
619 (labelled "Disk stream not available in time")
620 - Update effects on sample rate & period size changes (to avoid
621 crashes and noise on such transitions).
622 - ignore missing LADSPA paths without ignoring valid LADSPA paths
623 (fixes #208)
624 - Fixed bug in LSCP grammar definition which caused a statement like
625 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
626 practically irrelevant, however it caused problems with the new LSCP
627 shell's auto completion feature).
628 - Fixed MIDI program change messages being ignored if quickly executed
629 after each other (fixes #231).
630
631 Version 1.0.0 (31 July 2009)
632
633 * packaging changes:
634 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
635 causing e.g. the libgig test to fail when
636 "./configure --disable-jack-driver" was used
637 (patch by Alexis Ballier)
638 - fixed compilation with gcc 4.3
639 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

644 - minor fix in configure for mmsystem.h detection on MinGW
645 - Windows: look for editor plugins and Fantasia using base
646 directory of liblinuxsampler dll (look in the same directory and one
647 directory above)
648 - configure script fix: removed unconditional use of SSE
649 - fixed building with sqlite installed in a non-standard directory
650 - when cross-compiling, don't try to create instruments.db
651 - fix for new mingw-w64 version, which has usleep
652
653 * general changes:
654 - bugfix: on some POSIX systems instrument editor plugins refused to
655 load as we used a non-portable Linux specific struct field
656 (fixes bug #70, patch by Ronald Baljeu)
657 - fixed endless loop which occured when loading an instrument editor
658 plugin DLL on Windows systems failed
659 - fixed memory leaks that occurred when liblinuxsampler was unloaded
660 - optimized the SynchronizedConfig class so it doesn't wait
661 unnecessarily long after an update
662 - added support for notifying instrument editors on note-on / note-off
663 events (e.g. to highlight the pressed keys on the virtual keyboard
664 of gigedit)
665 - added support for triggering notes by instrument editors (see above)
666 - be verbose on DLL load errors (on Linux)
667 - fixed di-harmonic triangle LFO implementation (this LFO implementation
668 is only used by very few systems, most pick the int math
669 implementation, which is usually faster)
670 - fixes for audio drivers with varying buffer sizes
671 - experimental support for running LinuxSampler as a DSSI, LV2 and
672 VST plugin
673 - notification events for stream/voice count statistics are now sent
674 only when there are actual changes
675 - added memory ordering constraints to improve stability on
676 multi-core and multi-cpu systems
677 - maximum voices and disk streams can now be altered at runtime
678 - fixed CPU feature detection on x86_64 (maybe fixes #108)
679 - automatic stacktrace mechanism is now turned off by default and can
680 be switched on by command line option "--stacktrace" (the automatic
681 stacktrace mechanism seems to be broken on most systems at the moment)
682 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
683 a pointer to the launched InstrumentEditor object
684 - added optional 3rd party user data parameter for following
685 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
686 InstrumentEditor::Launch(),
687 InstrumentManager::LaunchInstrumentEditor()
688 - theoretical fix: made SynchronizedConfig follow C++0x memory
689 model more strictly
690 - fixes for using large audio device buffers
691 - Windows: add the installation directory to the DLL search path
692 when loading an editor plugin (solves problems with VST and
693 gigedit on systems with other GTK versions installed)
694 - updated linuxsampler man page
695
696 * audio driver:
697 - removed the nonsense audio channel constraint (which was hard coded to
698 max. 100 audio channels) for most audio drivers
699 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
700 opposed to the LSCP specs
701 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
702 reflected the wrong value
703 - fixed a memory management bug in ASIO driver
704 - Makefile fix: JACK_CFLAGS wasn't used
705 - JACK: use jack_client_open instead of the deprecated
706 jack_client_new

709 previous binary release but accidentally never committed to CVS
710 (fixes #117)
711 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
712 win64)
713 - VST: added support for sample rate and buffer size changes
714 - VST: close editor (Fantasia) when the VST is removed
715 - VST: avoid opening Fantasia more than once for each VST instance
716 - VST: export main function as "main" on Linux too (fix for
717 energyXT)
718 - VST: changed number of output channels from one stereo to 16
719 stereo
720 - added channel routing, fxsends and midi maps to the settings
721 stored in the plugin state
722 - performance optimization of AudioChannel::MixTo() and
723 AudioChannel::CopyTo() methods using GCC vector exensions
724 (if available)
725 - ASIO fixes: avoid initializing the device twice, avoid throwing
726 exception when getting parameters from a disconnected device
727
728 * MIDI driver:
729 - added JACK MIDI driver
730 - dispatch bank select as ordinary CC as well, the user might seriously
731 want to (mis)use it for some purpose ("fixed" in all current MIDI
732 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
733 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
734 CoreMidi or AU
735 - fixed mingw-w64 compilation error in MME driver
736 - made program change handling in MIDI thread real-time safe by
737 moving the logic to a non-RT thread
738 - fixed minor memory leak in ALSA driver
739
740 * instruments database:
741 - avoid time consuming samples scanning when adding instruments
742 to the instruments database

744 - Implemented option for adding instruments in separate directories
745 in the instruments database
746 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
747 - work-around for missing fnmatch function on Windows to make
748 instrument database compilable
749 - added instrument database support on Windows
750 works with both standalone mode and VST plugin.
751 the instruments DB file is located in
752 %USERPROFILE%\.linuxsampler\instruments.db which allows different
753 databases for each windows user
754 if no DB is present it automatically creates the .linuxsampler subdir
755 and then creates an empty DB
756 - fixed recursive import, which was broken on Windows
757
758 * Gigasampler format engine:
759 - fixed a memory leak that could happen when a channel was deleted
760 while notes were playing
761 - made it possible to load an instrument even if the audio thread
762 isn't running
763 - added partial support for the "Controller Triggered" MIDI rule,
764 enough for piano gigs with pedal noise samples
765 - minor fix: only mark FX sends as being modified if really the
766 respective FX send MIDI controller was used
767 - added support for GM global device volume SysEx message
768 (can be selected at compile time to either apply globally to the
769 whole sampler [default] or only to the sampler channels that are
770 connected to the respective MIDI input port the SysEx message arrived
771 on)
772 - bugfix: notes triggered at position 0 in the audio buffer were
773 sometimes wrongly killed in the same buffer, causing no sound to
774 be played
775 - added support for chromatic / drumkit mode Roland GS Sysex message
776 which is usally used to switch a part between chromatic sounds and
777 drumkit sounds (as opposed to their common default setting of MIDI
778 part 10 being a drumkit part and all other ones chromatic parts), in
779 LS however one can switch between the first 16 MIDI instrument maps
780 defined for the sampler
781 - made it possible to create multiple sample channels even if the
782 audio thread isn't running
783 - fixed crash when removing channel with active voices (#116)
784 - bugfix: on sample reference changes (instrument editor), only
785 un-cache the respective sample if it's really not used by any
786 sampler engine anymore
787 - re-cache samples in case they were changed by an instrument editor,
788 e.g. when a sample was added while playing (#82)
789 - fixed hanging notes which occured when note-off event had the exact
790 same time stamp as the voice's note-on event and occured both in the
791 same audio fragment cycle (fixes bug #112)
792 - added support for the "fine tune" and "pitch bend range"
793 instrument-level gig parameters
794 - fixed minor artifacts in pitch bend handling
795 - added support for GS Reset SysEx message
796 - allow gig files to use unlimited downward pitch shifting
797 - added a limit check for upward pitch shifting
798 - bugfix: sometimes, when playing a note twice fast, the second
799 note was silent
800 - fixed crash happening when a pitch bend event arrived at the
801 same time a new instrument was loading
802
803 * LSCP server:
804 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
805 react on MIDI data arriving on certain sampler channels (so far only
806 Note-On and Note-Off events are sent via this LSCP event)
807 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
808 react on MIDI data arriving on certain MIDI input devices (so far only
809 Note-On and Note-Off events are sent via this LSCP event)
810 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
811 SET DB_INSTRUMENT FILE_PATH
812 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
813 frontends to send MIDI messages to specific sampler channel
814 - added two additional fields to GET FILE INSTRUMENT INFO command -
815 KEY_BINDINGS and KEYSWITCH_BINDINGS
816 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
817 was incorrect
818 - Optimized the retrieval of the MIDI instrument mappings
819 - added new LSCP command "SET VOICES" to globally alter the maximum
820 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
821 be triggered respectively
822 - added new LSCP command "SET STREAMS" to globally alter the maximum
823 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
824 which will be triggered respectively
825 - bugfix: retry if "select" returns EINTR (this fixes a crash when
826 a gigedit file dialog is opened)
827 - close all connections when LSCPServer is deleted
828 - hard close of all sockets on exit
829 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
830 driver
831
832 * Bug fixes:
833 - fixed a crash which occurs when removing a sampler channel waiting
834 to start instrument loading after another channel
835 - fixed a crash which occurs when removing a sampler channel with
836 instrument loading in progress (bug #113)
837 - fixed termination caused by uncaught exception when adding MIDI
838 instrument with PERSISTENT load mode
839 - fixed possible iterator invalidations when resetting the sampler
840 - fixed memory leaks when issuing the following LSCP commands:
841 GET AUDIO_OUTPUT_DRIVER INFO
842 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
843 GET MIDI_INPUT_DRIVER INFO
844 GET MIDI_INPUT_DRIVER_PARAMETER INFO
845 - fixed possible compilation error when sqlite is not present
846 - fixed orphaned pointers when setting maximum voices limit (bug #118)
847 - fixed crash when changing the audio output device of a sampler
848 channel with loaded instrument and start playing notes
849 - fixed endless loop in Engine::SuspendAll() (bug #120)
850 - fixed a low-level atomic load function that was broken on 64-bit
851 PowerPC, which probably could cause crashes on that platform
852 - fixed a memory management error which could cause a crash when a
853 plugin was unloaded
854 - bugfix: two private structs had the same name, which could cause
855 problems if the linker chose the wrong constructor
856 - fixed low-level ConditionServer usage bug that caused lockups on
857 Windows
858
859
860 Version 0.5.1 (6 December 2007)
861
862 * packaging changes:
863 - added autoconf checks for pthread library
864 - added autoconf check for pthread bug found on certain NPTL-enabled
865 glibc versions (see Gentoo bug report #194076)
866 - added autoconf checks for MS Windows
867
868 * general changes:
869 - bugfix: the thread used by an editor plugin didn't die when the
870 editor closed
871 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
872 out all the space. operator--() did not apply size_mask after
873 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
874 order to avoid problems with the _NonVolatileReader functions.
875 - bugfix: Stream.h: added a missing divide by BytesPerSample in
876 GetWriteSpace(). Since this function is currently only used in
877 the stream's qsort() compare function, it didn't trigger any
878 bugs.
879 - Resampler.h, Synthesizer.h: cubic interpolation now works in
880 24bit mode too. Faster method to read 24bit words on little
881 endian machines (x86): replaced 3 byte reads + shifts with a 1
882 unaligned 32bit read and shift
883 - experimental support for MS Windows (MIDI input via MME, AUDIO
884 output via ASIO)
885 - made handling of SIGINT signal (Ctrl-C) a bit more robust
886 - support for monitoring the total number of active disk streams
887 (new LSCP commands: GET TOTAL_STREAM_COUNT,
888 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
889
890 * AUDIO driver:
891 - added Windows ASIO low latency audio driver
892
893 * MIDI driver:
894 - added MME Windows MIDI driver
895
896 * LSCP server:
897 - added support for Windows style path / filenames, however with
898 forward slash path separators instead of backslash
899 (i.e. "C:/foo/bar.gig")
900 - allow naughty liblscp to send non-string device parameters within
901 apostrophes as well
902 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
903 "LIST FILE INSTRUMENTS <file>" and
904 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
905 about an arbitrary instrument file on the system where the sampler is
906 running on
907
908 Version 0.5.0 (15 October 2007)
909
910 * packaging changes:
911 - config.h is not going to be installed along with liblinuxsampler's
912 API header files anymore
913 - only the API relevant header (and source) files will be exported to
914 the Doxygen API documentation (explicitly listed in Doxyfile.in)
915 - added completely new XCode project files for Mac OSX which is now
916 capable to execute our autoconf environment, thus no need anymore
917 to maintain the compile time configuration file (osx/version.h) for
918 OSX manually (patch by Toshi Nagata)
919 - fixed buggy boolean --enable-foo / --disable-foo configure script
920 parameters
921 - global.h now only covers global definitions that are needed for the
922 C++ API header files, all implementation internal global definitions
923 are now in global_private.h
924 - atomic.h is not exposed to the C++ API anymore
925 - no need to include config.h anymore for using LS's API header files
926 - fixed warnings in API doc generation
927
928 * general changes:
929 - replaced the old, confusing MIDI program change mechanism by a
930 flexible MIDI instrument mapper which allows to map arbitrary
931 (MIDI bank, MIDI program) pairs with arbitrary
932 (engine type, instrument file, file index) triplets which will be
933 loaded on the respective channel when such MIDI program change
934 messages arrive, beside that, each entry allows to define a life-time
935 strategy for the instrument, so the user can define whether the
936 instrument should i.e. be permanently loaded (to be able to switch
937 quickly among sounds) or i.e. loaded just on demand when the
938 respective program change arrives (to safe RAM space), as well as a
939 global volume factor for each entry, so the user can adjust the volume
940 dynamic of his mapped instrument collection without having to modify
941 the instrument files, also one can manage arbitrary amount of such
942 MIDI instrument maps and assign each sampler channel individually
943 a certain map, so that i.e. separation of normal instruments and
944 drumkits is possible
945 - new notification events for tracking changes to audio/MIDI devices,
946 MIDI instrument maps, MIDI instruments, FX sends, global volume.
947 - sampler was limited to load max. 200 instruments in the background
948 due to a constant size RingBuffer FIFO which is now replaced by a
949 dynamic (unlimited) size std::list FIFO
950 - added FX sends, these allow to route audio signals to arbitrary audio
951 output channels for being processed by external effect processors
952 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
953 controllers
954 - global (sampler wide) volume can now be controlled at runtime
955 - Implemented new, improved notification system
956 - fixed compilation errors regarding OSX
957 (patch by Toshi Nagata)
958 - implemented instruments database
959 - added support for escape sequences to the instruments database
960 - added highly experimental support for on-the-fly instrument editing
961 within the sampler's process (by using instrument editor plugins),
962 you'll notice the new "Registered instrument editors:" message on
963 startup, added a new LSCP command:
964 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
965 to spawn a matching instrument editor for the instrument on the
966 given sampler channel, the plugin path can be overridden at compile
967 time with ./configure --enable-plugin-dir=/some/dir
968 - added experimental code for synchronizing instrument editors hosted
969 in the sampler's process to safely edit instruments while playing
970 without a crash (hopefully) by either suspending single regions
971 wherever possible or if unavoidable whole engine(s)
972 - fixed several issues in fundamental "Thread" class: set scheduling
973 policy and priority on thread level, set a minimum stack size for
974 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
975 threads simply inherited properties of starting thread instead of
976 setting their own policy and priority
977 - minor fix in our automatic stack trace mechanism on crashes, the
978 main process did not wait for the stack trace process to finish
979 its output
980 - fixed some minor memory leaks
981 - reenabled assembly features support, at the moment only for
982 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
983 - minor assembly fix in x86 features detection (don't use the PIC
984 register, to avoid relocations in the text segment at runtime)
985 - POSIX callback functions of Thread.h are hidden
986
987 * MIDI driver:
988 - dispatch bank select (MSB and LSB) messages
989
990 * audio driver:
991 - the ALSA audio output driver parameters now reflect the correct
992 parameter value ranges for the respective selected sound card
993 (patch by Till Wimmer, a bit fixed and extended)
994
995 * Gigasampler format engine:
996 - if a filter is used and EG2 finishes before EG1, let the voice
997 die when EG2 has finished (this fixes a problem with clicks and
998 voice starvation for some gigs)
999 - playback is no longer disabled during instrument loading
1000 - all notes playing on a channel that changes its instrument keep
1001 playing with the old instrument until they get a note off
1002 command
1003 - EG fix: a release value of zero could cause noises or crash
1004 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1005 - EG fine tuning: when attack is zero the EG starts at a level
1006 above max sustain level, which means that there is a decay phase
1007 even if sustain is 100%
1008 - more EG fixes: the level could sometimes go below zero and cause
1009 noises or crashes
1010 - minor fix of EGDecay (patch by Toshi Nagata)
1011 - fixed compiler error when --enable-override-filter-type was
1012 supplied to the configure script (fixes #46)
1013 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1014 instead of a fix value
1015 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1016 127 (solo mode) only kill voices if the respective mode really
1017 changed
1018
1019 * LSCP server:
1020 - fixed compile time error for old Bison versions
1021 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1022 - parser now supports extended ASCII character set
1023 (up to ASCII code 255, i.e. includes now umlauts and accents)
1024 - filename arguments in LSCP commands now allow to use escape
1025 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1026 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1027 code value like \xf2) (fixes bug #24)
1028 - the following LSCP commands now also support escape sequences for at
1029 least one of their text-based parameters (i.e. name, description):
1030 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1031 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1032 "SET DB_INSTRUMENT_DIRECTORY NAME",
1033 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1034 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1035 "FIND DB_INSTRUMENT_DIRECTORIES"
1036 - returns verbose syntax errors (line and column where syntax error
1037 occured, the unexpected character and the actually expected, possible
1038 character(s), the latter only if less than 5 possibilities)
1039 - made sure that LSCP syntax is not affected by gigedit locale
1040 settings
1041 - bugfix regarding strings parameter lists: all comma separated lists
1042 of strings were treated as being one string containing commas
1043 (fixes #57)
1044
1045 * Bug fixes:
1046 - fixed crash occurring on certain LSCP scripts (Bug 39)
1047 - another thread safety fix for lscp "load engine" and "set
1048 channel audio output device"
1049 - fixed a crash which occurs when reassigning the same engine
1050 on a sampler channel with connected MIDI device
1051 - fixed a crash which occurs when changing the number of ports of a MIDI
1052 device connected to a sampler channel to number less then or equal
1053 to the index of the port to which the sampler channel is connected.
1054 - The previous bindings were not been disconnected when altering
1055 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1056 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1057 - The active stream/voice count statistic was incorrect.
1058 - notification events were not been sent for some sampler
1059 channel changes
1060 - added default min and max values to restrict the number of allowed
1061 audio output channels and MIDI input ports
1062 - the connection to the PCM interface is now closed when destroying
1063 an audio output device
1064 - files with slash in their path or filename could not be loaded
1065
1066 * test cases:
1067 - updated and fixed (haven't been touched in a while)
1068
1069 Version 0.4.0 (24 November 2006)
1070
1071 * packaging changes:
1072 - changed deprecated copyright attribute to license; added ldconfig
1073 to post-(un)install steps; added devel package for liblinuxsampler;
1074 to linuxsampler.spec (RPM)
1075 - install necessary development header files for allowing 3rd party
1076 applications to link against liblinuxsampler
1077 - liblinuxsampler's API documentation can be generated with 'make docs'
1078 (Doxygen required)
1079 - added benchmark to automatically detect the best triangle LFO
1080 implementation (currently either an integer math solution or a
1081 di-harmonic approximation), automatic detection can be overriden
1082 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1083 configure script argument though (mandatory for cross-compilation)
1084 - do not automatically pick optimized gcc flags if the user already
1085 provided some on his own (as CXXFLAGS)
1086 - added compile time option to disable processing of All-Notes-Off MIDI
1087 messages
1088 - added compile time options to allow disabling the various audio and
1089 MIDI drivers
1090 - fixed automatic GCC CPU switch detection on PPC
1091 (patch by Ebrahim Mayat)
1092
1093 * Gigasampler format engine:
1094 - extensive synthesis optimization
1095 (reimplementation of EGs and LFO(s), removed synthesis parameter
1096 prerendering and the synthesis parameter matrix in general, splitting
1097 each audio fragment into subfragments now where each subfragment uses
1098 constant pitch and filter coefficients. The volume coefficient is
1099 linearly interpolated inside a subfragment, unless
1100 --disable-interpolate-volume is set.)
1101 - fine tuning of the EG modulation parameters
1102 - improved filter cutoff calculation by adding support for the
1103 following gig parameters: Cutoff freq (used when no cutoff
1104 controller is defined), Control invert, Minimum cutoff, Velocity
1105 curve and Velocity range. The keyboard tracking now scales
1106 cutoff frequency instead of resonance.
1107 - added support for gig parameter Resonance.
1108 - fixed bug in sysex handling (patch by Juan Linietsky)
1109 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1110 which can be overridden with --enable-global-attenuation
1111 - EG fixes: made the length of "attack hold" stage more
1112 accurate. Release stage can now start before attack stage
1113 ends. Cancel release didn't work when sustain was zero. Attack
1114 time now has a minimal value to prevent clicks.
1115 - fixed pitch changes larger than one octave
1116 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1117 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1118 all modes can be altered via standard GM messages, that is CC5 for
1119 altering portamento time, CC65 for enabling / disabling portamento
1120 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1121 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1122 parameter) and crossfade
1123 - added support for the "attenuation controller threshold" gig
1124 parameter
1125 - added smoothing of volume changes caused by control change
1126 messages
1127 - sample loop parameters are now taken from the DimensionRegion
1128 instead of the wave chunk
1129 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1130 not equal to a power of two
1131 - reimplementation of the filter algorithm. The new filter is more
1132 accurate and supports all gig filter types, including bandreject
1133 and lowpass turbo.
1134 - real support for 24 bit samples - samples are not truncated to
1135 16 bits anymore
1136 - support for aftertouch (channel pressure, not polyphonic
1137 aftertouch)
1138 - LFO1 behaviour fixed (dampening from max volume instead of
1139 amplifying from 0)
1140
1141 * LSCP server:
1142 - fixed application exit on broken pipe error (fixes bug #20)
1143 - fixed the notification messages delay due to lack of
1144 network activity (fixes bug #26)
1145 - fixed parser bug which occured on space(s) within device parameters
1146 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1147
1148 * audio driver:
1149 - added aRts audio output driver (by no means RT safe)
1150
1151 * MIDI driver:
1152 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1153 messages several times instead of once
1154 - API extension for MIDI drivers which already supply exact time stamps
1155 for events (i.e. for offline rendering based MIDI drivers)
1156 - added checks for bad MIDI data
1157
1158 * linuxsampler application:
1159 - show available sampler engine types on startup
1160
1161 * general changes:
1162 - support for muting sampler channels and solo mode of the same, two new
1163 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1164 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1165 introduced for this, the behavior is the same like on a mixer console
1166 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1167 --enable-process-muted-channels which can be used to enable the
1168 processing of muted channels.
1169 - support for sostenuto pedal
1170 - support for monitoring the total number of active voices
1171 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1172 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1173 - fixed some memory management errors
1174 - fixed some concurrency problems that could lead to crashes when
1175 LSCP commands were executed
1176 - fixed crash when instrument loading failed previously on the same
1177 sampler channel (fixes bug #36)
1178
1179 Version 0.3.3 (15 July 2005)
1180
1181 * packaging changes:
1182 - fixed compilation with gcc 4.0
1183
1184 * Gigasampler format engine:
1185 - LFO preprocessing was performed even though the respective LFO was
1186 disabled by the instrument patch (minor efficiency fix)
1187 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1188 for volume ramp downs in the same fragment (needed for current voice
1189 stealing implementation) then simply inform the user with a warning
1190 about possible click sounds and reduce the volume ramp down
1191 appropriately instead of cancelling the audio device connection
1192
1193 Version 0.3.2 (24 June 2005)
1194
1195 * packaging changes:
1196 - updated autotools build files to compile on OS X
1197 (conditional compilation of CoreMIDI and MidiShare drivers)
1198 - hand-crafted assembly optimization code can be disabled with
1199 './configure --disable-asm' (definitely not recommended)
1200 - fixed 'make dist' rule to include all necessary files
1201 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1202 (due to 'dist-bzip2' automake option)
1203
1204 * Gigasampler format engine:
1205 - support for the gig parameters for "release velocity response" curves
1206 - fine tuning of the EGADSR envelope
1207 - volume of release triggered samples now depends on note-on velocity,
1208 note length and gig parameter "release trigger decay" instead of
1209 note-off velocity.
1210 - revised voice stealing
1211 (fixes crash and endless loop caused by voice stealing)
1212 - don't reset scale tuning on instrument or audio output device change
1213 - handle key group conflicts right at the beginning of each fragment
1214 instead of when the respective voice is actually launched
1215 (fixes undefined behavior if stolen voices belonged to a key group -
1216 this case was followed by a "killed voice survived" error message)
1217 - fixed minor issue with null/silence samples
1218 (those stole voices even though they don't need a voice at all which
1219 resulted in "voice stealing didn't work out" messages)
1220 - don't reset volume, pan, pitch and MIDI controller values on
1221 instrument or audio output device change
1222
1223 * LSCP server:
1224 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1225 - fixed LSCP event "CHANNEL_INFO" notification
1226 (e.g. did not notify on volume changes or MIDI program change events)
1227
1228 * linuxsampler application:
1229 - added command line parameters --lscp-addr and --lscp-port to override
1230 default IP address and port of LSCP server
1231
1232 Version 0.3.1 (24 May 2005)
1233
1234 * initial release
