Revision 2911 - (show annotations) (download)
Mon May 16 20:27:33 2016 UTC (7 years, 10 months ago) by schoenebeck
File size: 64072 byte(s)
* NKSP language grammar correction: allow empty event handler bodies
  like "on note end on".
* Bumped version (2.0.0.svn9).

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
24 * packaging changes:
25 - removed unnecessary dependency to libuuid
26 (originated by libgig's usage of it)
27 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28 auto detect whether it (sh/c)ould output its messages in color.
29
30 * Real-time instrument scripts:
31 - Implemented scheduler for delayed MIDI events and for suspended scripts.
32 - Built-in script function "wait()": implemented support for function's
33 "duration-us" argument, thus scripts using this function are now
34 correctly resumed after the requested amount of microseconds.
35 - Built-in script function "play_note()": implemented support for
36 function's "duration-us" argument, thus notes triggered with this
37 argument are now correctly released after the requested amount of
38 microseconds.
39 - Fix: script events were not cleared when engine channel was reset,
40 potentially causing undefined behavior.
41 - Fixed crash which happened when trying to reference an undeclared
42 variable.
43 - Built-in script function "play_note()": Added support for passing
44 special value -1 for "duration-us" argument, which will cause the
45 triggered note to be released once the original note was released.
46 - Instrument script classes now exported with the liblinuxsampler C++ API.
47 - Added new API method ScriptVM::syntaxHighlighting() which provides
48 a convenient syntax highlighting backend for external instrument
49 script editor applications.
50 - Added new C++ API class "ScriptVMFactory".
51 - Extended parser issues to provide not only first line and first
52 column, but also last line and last column of issue (thus marking
53 the precise span of the issue within the source code).
54 - Reload script automatically after being modified by an instrument
55 editor.
56 - NKSP language grammar correction: allow empty event handler bodies
57 like "on note end on".
58
59 Version 2.0.0 (15 July 2015)
60

78 - lsatomic.h: use gcc provided atomic functions if building with
79 gcc 4.7 and C++11
80 - modernized configure script
81 - fixed linkage error when building with
82 LDFLAGS="-Wl,--no-undefined" (#190)
83 - fixed compilation with Clang 3.2

88 makefiles
89 - fix for building with bison 3.0 (#202)
90 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
91 on the process's main thread
92 - fixed build error on newer MinGW
93 - support building with older jack versions
94 - support building with spaces in vst sdk path
95 - enabled automake 'subdir-objects' option and moved external
96 source references (vst, au, asio) from makefiles to cpp files,
97 in order to get rid of warnings from automake 1.14
98
99 * general changes:
100 - Refactoring: moved the independent code from
101 the Gigasampler format engine to base classes
102 - command line option '--profile' is currently disabled, since the
103 respective profiling code is currently broken
104 - Introduced support for optional environment variable
105 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
106 where the sampler shall look for instrument editor plugins
107 (patch by Luis Garrido, slightly modified).
108 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
109 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
110 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
111 note (in this implementation of the sampler its simply hard routed to
112 the 1st effect send of the sampler channel, no matter what the actual
113 effect type is)
114 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
115 note (in this implementation of the sampler its simply hard routed to
116 the 2nd effect send of the sampler channel, no matter what the actual
117 effect type is)
118 - implemented support for internal LADSPA effects
119 - raised limit of program change queue from 100 to 512
120 (as suggested by Alex Stone)
121 - implemented sine LFO, pulse LFO and saw LFO
122 - experimental support for per voice equalization
123 - added command line option --exec-after-init
124 - Introduced new C++ API method:
125 EngineChannel::InstrumentFileName(int index)
126 allowing to retrieve the whole list of files used for the loaded
127 instrument on an engine channel (a.k.a. part). Some GigaStudio
128 instruments for example are splitted over several files like
129 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
130 - Added new C++ API method Sampler::GetGlobalMaxVoices().
131 - Added new C++ API method Sampler::GetGlobalMaxStreams().
132 - Added new C++ API method Sampler::SetGlobalMaxVoices().
133 - Added new C++ API method Sampler::SetGlobalMaxStreams().
134 - Various "const" and "restrict" optimizations.
135 - all engines: add pan CC value to instrument pan parameter before
136 applying panning, instead of using two separate pan functions in
137 series (#182)
138 - added a lock guard class for exception safe mutex handling and
139 used it everywhere appropriate
140 - Immediately apply scale tuning changes to active voices.
141 - Exposed scale tuning to C++ API (along to the already existing standard
142 SysEx way).
143 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
144 and broken for ppc64. (Seq_cst loads and stores are actually not
145 used in LS, so the bug wasn't noticable.)
146 - lsatomic.h: added ARMv7 support
147 - Added support for multiple MIDI input ports per sampler channel (and
148 added various new C++ methods for this new feature / design change, old
149 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
150 as deprecated but are still there and should provide full behavior
151 backward compatibility).
152 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
153 unsafe and caused compilation error with clang 2.x).
154 - Bugfix: only process the latest MIDI program change event.
155 - Introducing the LSCP shell, which provides convenient control of the
156 sampler from the command line by providing LSCP aware features.
157 - VirtualMidiDevice: Added support for program change.
158 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
159 - VirtualMidiDevice: Added support for pitch bend.
160 - Aftertouch: extended API to explicitly handle channel pressure and
161 polyphonic key pressure events (so far polyphonic pressure was not
162 supported at all, and channel pressure was rerouted as CC128 but not
163 used so far).
164 - Added initial support for real-time instrument scripts. The script VM
165 code is shared by all sampler engine implemementations, however only the
166 gig file format currently provides support for storing instrument scripts
167 (as LinuxSampler extension to the original GigaStudio 4 format).
168

174 key
175 - bugfix: pitch LFO controller "internal+aftertouch" was broken
176 - bugfix: filter keyboard tracking was broken
177 - filter performance fix (an unnecessary copy was made of the
178 filter parameters in each sub fragment)
179 - handle special case when pan parameter in gig file has max or
180 min value
181 - Exclusive Groups: don't ever stop voices of the same note,
182 doesn't sound naturally with a drumkit
183 - fixed EG1 modulation when attack or release is zero
184 - Fixed support for 'aftertouch' attenuation controller.
185 - Fixed crash that happened with velocity split sounds under certain
186 conditions (see also previous commit on libgig).
187 - fixed behaviour of filter LFO
188

351 - bugfix: line numbers in error messages were wrong after "#include"
352 - added support for float and 32 bit sample files
353
354 * SoundFont format engine:
355 - Initial implementation (not usable yet)
356 - RT-safeness: avoid malloc in audio thread
357 - fixed a bug that could cause voice stealing to fail
358 - fine-tuned amplitude EG (by switching from gig to sfz EG)
359 - initial implementation of Vibrato LFO and Modulation LFO
360 - initial implementation of cutoff filter
361 - use linear decay and release for filter and pitch EG
362
363 * Host plugins (VST, AU, LV2, DSSI):
364 - AU bugfix: failed to destroy its audio/MIDI devices
365 - Listen to all interfaces on Mac OS X (INADDR_ANY)
366 - VST bugfix: If the host called resume() before and after
367 changing sample rate or block size, the number of channels was
368 incorrectly set to two. This caused silence in Cubase 5.
369 - save engine type (gig, sfz or sf2) in plugin state
370 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
371 64 bit Windows
372 - AU: changed number of output channels from one stereo to 16
373 stereo
374 - VST: made it possible to build the VST plugin for Mac
375 - AU: link AU plugin dynamically if --disable-shared isn't
376 specified
377 - LV2 "state" extension support (patch by David Robillard)
378 - VST bugfix: instrument loading hang and crashed the host when
379 the plugin was loaded a second time (#174)
380 - plugin bugfix: instrument loading hang when the plugin was
381 loaded a second time (this time it's for Linux and Mac, previous
382 similar fix was for Windows)
383 - thread safety fixes for the instrument loading thread
384 - LV2: use the new lv2 package if present
385 - VST: try to open Fantasia automatically on Linux and Mac too (on
386 Linux, the Fantasia jar should be placed in <prefix>/share/java)
387 - VST: fixed crashes on Linux Ardour and EnergyXT
388 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
389 port and audio channel routing for DSSI plugins are now visible.
390 - LV2: use urid and atom extensions instead of deprecated uri-map
391 and event
392 - LV2: lv2 package 1.0 is now required to build the LV2 plugin
393 - LV2: changed number of output channels to 16 stereo, just like
394 the VST and AU plugins
395 - LV2: fixed save/restore of SFZ state (patch by David Robillard)
396 - LV2: made LV2 plugin buildable on Windows and Mac
397 - VST: implemented retrieval and switching of programs using the
398 sampler's internal MIDI instrument mapping system
399
400 * Instrument editor interface:
401 - Changed instrument editor plugin interface, providing additional
402 informations like the EngineChannel for which the instrument editor was
403 spawned for. This allows the instrument editors to interact more actively
404 with the sampler.
405
406 * MIDI driver:
407 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
408 the ALSA sequencer client name
409 - removed limit of maximum amount of MIDI ports per MIDI device, since
410 there is no reason for this limit
411 - MME: fixed memory handling bug found with cppcheck
412 - MME: removed compiler warning
413 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
414 which allows to retrieve the list of CoreMIDI clients / ports and to connect
415 to them a la JACK, via the usual sampler APIs
416 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled

550 channel to a different engine type
551 - fixed crash when deleting a sampler channel or changing engine
552 type while an instrument load was in progress
553 - bugfix: playing a note while changing the instrument could cause
554 a crash, or give "Handing back unknown region" error messages
555 - bugfix: calling SET VOICES (which Fantasia does on start and
556 refresh) could cause instruments to be unloaded
557 - Mac OS X: fixed name collision of enum in EffectControl and
558 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
559 - Mac OS X: fixed hanging threads
560 - Windows: disabled the previous thread fix on non-Mac systems, as
561 it caused hanging threads on Windows
562 - Fixed possible crashes due to corrupted MIDI/audio device list
563 after MIDI/audio device creation failure
564 - When creating MIDI instrument map entries with "PERSISTENT" type, the
565 instruments were uselessly precached with zero samples, however it still
566 took the full preloading time and on 1st program change the respective
567 instrument was completely reloaded again.
568 - fixed handling of rapid bank select and program change messages
569 sent to the same sampler channel (patch from the Open Octave
570 project, slightly adjusted)

585 playing a note in a key group
586 - fixed erroneous error message piping in VoiceBase.h
587 (labelled "Disk stream not available in time")
588 - Update effects on sample rate & period size changes (to avoid
589 crashes and noise on such transitions).
590 - ignore missing LADSPA paths without ignoring valid LADSPA paths
591 (fixes #208)
592 - Fixed bug in LSCP grammar definition which caused a statement like
593 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
594 practically irrelevant, however it caused problems with the new LSCP
595 shell's auto completion feature).
596 - Fixed MIDI program change messages being ignored if quickly executed
597 after each other (fixes #231).
598
599 Version 1.0.0 (31 July 2009)
600
601 * packaging changes:
602 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
603 causing e.g. the libgig test to fail when
604 "./configure --disable-jack-driver" was used
605 (patch by Alexis Ballier)
606 - fixed compilation with gcc 4.3
607 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

611 - fixed building with libgig installed in a non-standard directory
612 - minor fix in configure for mmsystem.h detection on MinGW
613 - Windows: look for editor plugins and Fantasia using base
614 directory of liblinuxsampler dll (look in the same directory and one
615 directory above)
616 - configure script fix: removed unconditional use of SSE
617 - fixed building with sqlite installed in a non-standard directory
618 - when cross-compiling, don't try to create instruments.db
619 - fix for new mingw-w64 version, which has usleep
620
621 * general changes:
622 - bugfix: on some POSIX systems instrument editor plugins refused to
623 load as we used a non-portable Linux specific struct field
624 (fixes bug #70, patch by Ronald Baljeu)
625 - fixed endless loop which occured when loading an instrument editor
626 plugin DLL on Windows systems failed
627 - fixed memory leaks that occurred when liblinuxsampler was unloaded
628 - optimized the SynchronizedConfig class so it doesn't wait
629 unnecessarily long after an update
630 - added support for notifying instrument editors on note-on / note-off
631 events (e.g. to highlight the pressed keys on the virtual keyboard
632 of gigedit)
633 - added support for triggering notes by instrument editors (see above)
634 - be verbose on DLL load errors (on Linux)
635 - fixed di-harmonic triangle LFO implementation (this LFO implementation
636 is only used by very few systems, most pick the int math
637 implementation, which is usually faster)
638 - fixes for audio drivers with varying buffer sizes
639 - experimental support for running LinuxSampler as a DSSI, LV2 and
640 VST plugin
641 - notification events for stream/voice count statistics are now sent
642 only when there are actual changes

644 multi-core and multi-cpu systems
645 - maximum voices and disk streams can now be altered at runtime
646 - fixed CPU feature detection on x86_64 (maybe fixes #108)
647 - automatic stacktrace mechanism is now turned off by default and can
648 be switched on by command line option "--stacktrace" (the automatic
649 stacktrace mechanism seems to be broken on most systems at the moment)
650 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
651 a pointer to the launched InstrumentEditor object
652 - added optional 3rd party user data parameter for following
653 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
654 InstrumentEditor::Launch(),
655 InstrumentManager::LaunchInstrumentEditor()
656 - theoretical fix: made SynchronizedConfig follow C++0x memory
657 model more strictly
658 - fixes for using large audio device buffers
659 - Windows: add the installation directory to the DLL search path
660 when loading an editor plugin (solves problems with VST and
661 gigedit on systems with other GTK versions installed)
662 - updated linuxsampler man page
663
664 * audio driver:
665 - removed the nonsense audio channel constraint (which was hard coded to
666 max. 100 audio channels) for most audio drivers
667 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
668 opposed to the LSCP specs
669 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
670 reflected the wrong value
671 - fixed a memory management bug in ASIO driver
672 - Makefile fix: JACK_CFLAGS wasn't used
673 - JACK: use jack_client_open instead of the deprecated
674 jack_client_new

680 win64)
681 - VST: added support for sample rate and buffer size changes
682 - VST: close editor (Fantasia) when the VST is removed
683 - VST: avoid opening Fantasia more than once for each VST instance
684 - VST: export main function as "main" on Linux too (fix for
685 energyXT)
686 - VST: changed number of output channels from one stereo to 16
687 stereo
688 - added channel routing, fxsends and midi maps to the settings
689 stored in the plugin state
690 - performance optimization of AudioChannel::MixTo() and
691 AudioChannel::CopyTo() methods using GCC vector exensions
692 (if available)
693 - ASIO fixes: avoid initializing the device twice, avoid throwing
694 exception when getting parameters from a disconnected device
695
696 * MIDI driver:
697 - added JACK MIDI driver
698 - dispatch bank select as ordinary CC as well, the user might seriously
699 want to (mis)use it for some purpose ("fixed" in all current MIDI
700 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
701 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
702 CoreMidi or AU
703 - fixed mingw-w64 compilation error in MME driver
704 - made program change handling in MIDI thread real-time safe by
705 moving the logic to a non-RT thread
706 - fixed minor memory leak in ALSA driver
707
708 * instruments database:
709 - avoid time consuming samples scanning when adding instruments
710 to the instruments database

712 - Implemented option for adding instruments in separate directories
713 in the instruments database
714 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
715 - work-around for missing fnmatch function on Windows to make
716 instrument database compilable
717 - added instrument database support on Windows
718 works with both standalone mode and VST plugin.
719 the instruments DB file is located in
720 %USERPROFILE%\.linuxsampler\instruments.db which allows different
721 databases for each windows user
722 if no DB is present it automatically creates the .linuxsampler subdir
723 and then creates an empty DB
724 - fixed recursive import, which was broken on Windows
725
726 * Gigasampler format engine:
727 - fixed a memory leak that could happen when a channel was deleted
728 while notes were playing
729 - made it possible to load an instrument even if the audio thread
730 isn't running
731 - added partial support for the "Controller Triggered" MIDI rule,
732 enough for piano gigs with pedal noise samples
733 - minor fix: only mark FX sends as being modified if really the
734 respective FX send MIDI controller was used
735 - added support for GM global device volume SysEx message
736 (can be selected at compile time to either apply globally to the
737 whole sampler [default] or only to the sampler channels that are
738 connected to the respective MIDI input port the SysEx message arrived
739 on)
740 - bugfix: notes triggered at position 0 in the audio buffer were
741 sometimes wrongly killed in the same buffer, causing no sound to
742 be played
743 - added support for chromatic / drumkit mode Roland GS Sysex message
744 which is usally used to switch a part between chromatic sounds and
745 drumkit sounds (as opposed to their common default setting of MIDI
746 part 10 being a drumkit part and all other ones chromatic parts), in
747 LS however one can switch between the first 16 MIDI instrument maps
748 defined for the sampler
749 - made it possible to create multiple sample channels even if the
750 audio thread isn't running
751 - fixed crash when removing channel with active voices (#116)
752 - bugfix: on sample reference changes (instrument editor), only
753 un-cache the respective sample if it's really not used by any
754 sampler engine anymore
755 - re-cache samples in case they were changed by an instrument editor,
756 e.g. when a sample was added while playing (#82)
757 - fixed hanging notes which occured when note-off event had the exact
758 same time stamp as the voice's note-on event and occured both in the
759 same audio fragment cycle (fixes bug #112)
760 - added support for the "fine tune" and "pitch bend range"
761 instrument-level gig parameters
762 - fixed minor artifacts in pitch bend handling
763 - added support for GS Reset SysEx message
764 - allow gig files to use unlimited downward pitch shifting
765 - added a limit check for upward pitch shifting
766 - bugfix: sometimes, when playing a note twice fast, the second
767 note was silent
768 - fixed crash happening when a pitch bend event arrived at the
769 same time a new instrument was loading
770
771 * LSCP server:
772 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
773 react on MIDI data arriving on certain sampler channels (so far only
774 Note-On and Note-Off events are sent via this LSCP event)
775 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
776 react on MIDI data arriving on certain MIDI input devices (so far only
777 Note-On and Note-Off events are sent via this LSCP event)
778 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
779 SET DB_INSTRUMENT FILE_PATH
780 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
781 frontends to send MIDI messages to specific sampler channel
782 - added two additional fields to GET FILE INSTRUMENT INFO command -
783 KEY_BINDINGS and KEYSWITCH_BINDINGS
784 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
785 was incorrect
786 - Optimized the retrieval of the MIDI instrument mappings
787 - added new LSCP command "SET VOICES" to globally alter the maximum
788 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
789 be triggered respectively
790 - added new LSCP command "SET STREAMS" to globally alter the maximum
791 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
792 which will be triggered respectively
793 - bugfix: retry if "select" returns EINTR (this fixes a crash when
794 a gigedit file dialog is opened)
795 - close all connections when LSCPServer is deleted
796 - hard close of all sockets on exit
797 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
798 driver
799
800 * Bug fixes:
801 - fixed a crash which occurs when removing a sampler channel waiting
802 to start instrument loading after another channel
803 - fixed a crash which occurs when removing a sampler channel with
804 instrument loading in progress (bug #113)
805 - fixed termination caused by uncaught exception when adding MIDI
806 instrument with PERSISTENT load mode
807 - fixed possible iterator invalidations when resetting the sampler
808 - fixed memory leaks when issuing the following LSCP commands:
809 GET AUDIO_OUTPUT_DRIVER INFO
810 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
811 GET MIDI_INPUT_DRIVER INFO
812 GET MIDI_INPUT_DRIVER_PARAMETER INFO
813 - fixed possible compilation error when sqlite is not present
814 - fixed orphaned pointers when setting maximum voices limit (bug #118)
815 - fixed crash when changing the audio output device of a sampler
816 channel with loaded instrument and start playing notes
817 - fixed endless loop in Engine::SuspendAll() (bug #120)
818 - fixed a low-level atomic load function that was broken on 64-bit
819 PowerPC, which probably could cause crashes on that platform
820 - fixed a memory management error which could cause a crash when a
821 plugin was unloaded
822 - bugfix: two private structs had the same name, which could cause
823 problems if the linker chose the wrong constructor
824 - fixed low-level ConditionServer usage bug that caused lockups on
825 Windows
826
827
828 Version 0.5.1 (6 December 2007)
829
830 * packaging changes:
831 - added autoconf checks for pthread library
832 - added autoconf check for pthread bug found on certain NPTL-enabled
833 glibc versions (see Gentoo bug report #194076)
834 - added autoconf checks for MS Windows
835
836 * general changes:
837 - bugfix: the thread used by an editor plugin didn't die when the
838 editor closed
839 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
840 out all the space. operator--() did not apply size_mask after
841 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
842 order to avoid problems with the _NonVolatileReader functions.
843 - bugfix: Stream.h: added a missing divide by BytesPerSample in
844 GetWriteSpace(). Since this function is currently only used in
845 the stream's qsort() compare function, it didn't trigger any
846 bugs.
847 - Resampler.h, Synthesizer.h: cubic interpolation now works in
848 24bit mode too. Faster method to read 24bit words on little
849 endian machines (x86): replaced 3 byte reads + shifts with a 1
850 unaligned 32bit read and shift
851 - experimental support for MS Windows (MIDI input via MME, AUDIO
852 output via ASIO)
853 - made handling of SIGINT signal (Ctrl-C) a bit more robust
854 - support for monitoring the total number of active disk streams
855 (new LSCP commands: GET TOTAL_STREAM_COUNT,
856 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
857
858 * AUDIO driver:
859 - added Windows ASIO low latency audio driver
860
861 * MIDI driver:
862 - added MME Windows MIDI driver
863
864 * LSCP server:
865 - added support for Windows style path / filenames, however with
866 forward slash path separators instead of backslash
867 (i.e. "C:/foo/bar.gig")
868 - allow naughty liblscp to send non-string device parameters within
869 apostrophes as well
870 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
871 "LIST FILE INSTRUMENTS <file>" and
872 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
873 about an arbitrary instrument file on the system where the sampler is
874 running on
875
876 Version 0.5.0 (15 October 2007)
877
878 * packaging changes:
879 - config.h is not going to be installed along with liblinuxsampler's
880 API header files anymore
881 - only the API relevant header (and source) files will be exported to
882 the Doxygen API documentation (explicitly listed in Doxyfile.in)
883 - added completely new XCode project files for Mac OSX which is now
884 capable to execute our autoconf environment, thus no need anymore
885 to maintain the compile time configuration file (osx/version.h) for
886 OSX manually (patch by Toshi Nagata)
887 - fixed buggy boolean --enable-foo / --disable-foo configure script
888 parameters
889 - global.h now only covers global definitions that are needed for the
890 C++ API header files, all implementation internal global definitions
891 are now in global_private.h
892 - atomic.h is not exposed to the C++ API anymore
893 - no need to include config.h anymore for using LS's API header files
894 - fixed warnings in API doc generation
895
896 * general changes:
897 - replaced the old, confusing MIDI program change mechanism by a
898 flexible MIDI instrument mapper which allows to map arbitrary
899 (MIDI bank, MIDI program) pairs with arbitrary
900 (engine type, instrument file, file index) triplets which will be
901 loaded on the respective channel when such MIDI program change
902 messages arrive, beside that, each entry allows to define a life-time
903 strategy for the instrument, so the user can define whether the
904 instrument should i.e. be permanently loaded (to be able to switch
905 quickly among sounds) or i.e. loaded just on demand when the
906 respective program change arrives (to safe RAM space), as well as a
907 global volume factor for each entry, so the user can adjust the volume
908 dynamic of his mapped instrument collection without having to modify
909 the instrument files, also one can manage arbitrary amount of such
910 MIDI instrument maps and assign each sampler channel individually
911 a certain map, so that i.e. separation of normal instruments and
912 drumkits is possible
913 - new notification events for tracking changes to audio/MIDI devices,
914 MIDI instrument maps, MIDI instruments, FX sends, global volume.
915 - sampler was limited to load max. 200 instruments in the background
916 due to a constant size RingBuffer FIFO which is now replaced by a
917 dynamic (unlimited) size std::list FIFO
918 - added FX sends, these allow to route audio signals to arbitrary audio
919 output channels for being processed by external effect processors
920 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
921 controllers
922 - global (sampler wide) volume can now be controlled at runtime
923 - Implemented new, improved notification system
924 - fixed compilation errors regarding OSX
925 (patch by Toshi Nagata)
926 - implemented instruments database
927 - added support for escape sequences to the instruments database
928 - added highly experimental support for on-the-fly instrument editing
929 within the sampler's process (by using instrument editor plugins),
930 you'll notice the new "Registered instrument editors:" message on
931 startup, added a new LSCP command:
932 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
933 to spawn a matching instrument editor for the instrument on the
934 given sampler channel, the plugin path can be overridden at compile
935 time with ./configure --enable-plugin-dir=/some/dir
936 - added experimental code for synchronizing instrument editors hosted
937 in the sampler's process to safely edit instruments while playing
938 without a crash (hopefully) by either suspending single regions
939 wherever possible or if unavoidable whole engine(s)
940 - fixed several issues in fundamental "Thread" class: set scheduling
941 policy and priority on thread level, set a minimum stack size for
942 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
943 threads simply inherited properties of starting thread instead of
944 setting their own policy and priority
945 - minor fix in our automatic stack trace mechanism on crashes, the
946 main process did not wait for the stack trace process to finish
947 its output
948 - fixed some minor memory leaks
949 - reenabled assembly features support, at the moment only for
950 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
951 - minor assembly fix in x86 features detection (don't use the PIC
952 register, to avoid relocations in the text segment at runtime)
953 - POSIX callback functions of Thread.h are hidden
954
955 * MIDI driver:
956 - dispatch bank select (MSB and LSB) messages
957
958 * audio driver:
959 - the ALSA audio output driver parameters now reflect the correct
960 parameter value ranges for the respective selected sound card
961 (patch by Till Wimmer, a bit fixed and extended)
962
963 * Gigasampler format engine:
964 - if a filter is used and EG2 finishes before EG1, let the voice
965 die when EG2 has finished (this fixes a problem with clicks and
966 voice starvation for some gigs)
967 - playback is no longer disabled during instrument loading
968 - all notes playing on a channel that changes its instrument keep
969 playing with the old instrument until they get a note off
970 command
971 - EG fix: a release value of zero could cause noises or crash
972 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
973 - EG fine tuning: when attack is zero the EG starts at a level
974 above max sustain level, which means that there is a decay phase
975 even if sustain is 100%
976 - more EG fixes: the level could sometimes go below zero and cause
977 noises or crashes
978 - minor fix of EGDecay (patch by Toshi Nagata)
979 - fixed compiler error when --enable-override-filter-type was
980 supplied to the configure script (fixes #46)
981 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
982 instead of a fix value
983 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
984 127 (solo mode) only kill voices if the respective mode really
985 changed
986
987 * LSCP server:
988 - fixed compile time error for old Bison versions
989 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
990 - parser now supports extended ASCII character set
991 (up to ASCII code 255, i.e. includes now umlauts and accents)
992 - filename arguments in LSCP commands now allow to use escape
993 sequences, that is directly literal as one of: \', \", \\, \n, \r,
994 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
995 code value like \xf2) (fixes bug #24)
996 - the following LSCP commands now also support escape sequences for at
997 least one of their text-based parameters (i.e. name, description):
998 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
999 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1000 "SET DB_INSTRUMENT_DIRECTORY NAME",
1001 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1002 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1003 "FIND DB_INSTRUMENT_DIRECTORIES"
1004 - returns verbose syntax errors (line and column where syntax error
1005 occured, the unexpected character and the actually expected, possible
1006 character(s), the latter only if less than 5 possibilities)
1007 - made sure that LSCP syntax is not affected by gigedit locale
1008 settings
1009 - bugfix regarding strings parameter lists: all comma separated lists
1010 of strings were treated as being one string containing commas
1011 (fixes #57)
1012
1013 * Bug fixes:
1014 - fixed crash occurring on certain LSCP scripts (Bug 39)
1015 - another thread safety fix for lscp "load engine" and "set
1016 channel audio output device"
1017 - fixed a crash which occurs when reassigning the same engine
1018 on a sampler channel with connected MIDI device
1019 - fixed a crash which occurs when changing the number of ports of a MIDI
1020 device connected to a sampler channel to number less then or equal
1021 to the index of the port to which the sampler channel is connected.
1022 - The previous bindings were not been disconnected when altering
1023 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1024 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1025 - The active stream/voice count statistic was incorrect.
1026 - notification events were not been sent for some sampler
1027 channel changes
1028 - added default min and max values to restrict the number of allowed
1029 audio output channels and MIDI input ports
1030 - the connection to the PCM interface is now closed when destroying
1031 an audio output device
1032 - files with slash in their path or filename could not be loaded
1033
1034 * test cases:
1035 - updated and fixed (haven't been touched in a while)
1036
1037 Version 0.4.0 (24 November 2006)
1038
1039 * packaging changes:
1040 - changed deprecated copyright attribute to license; added ldconfig
1041 to post-(un)install steps; added devel package for liblinuxsampler;
1042 to linuxsampler.spec (RPM)
1043 - install necessary development header files for allowing 3rd party
1044 applications to link against liblinuxsampler
1045 - liblinuxsampler's API documentation can be generated with 'make docs'
1046 (Doxygen required)
1047 - added benchmark to automatically detect the best triangle LFO
1048 implementation (currently either an integer math solution or a
1049 di-harmonic approximation), automatic detection can be overriden
1050 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1051 configure script argument though (mandatory for cross-compilation)
1052 - do not automatically pick optimized gcc flags if the user already
1053 provided some on his own (as CXXFLAGS)
1054 - added compile time option to disable processing of All-Notes-Off MIDI
1055 messages
1056 - added compile time options to allow disabling the various audio and
1057 MIDI drivers
1058 - fixed automatic GCC CPU switch detection on PPC
1059 (patch by Ebrahim Mayat)
1060
1061 * Gigasampler format engine:
1062 - extensive synthesis optimization
1063 (reimplementation of EGs and LFO(s), removed synthesis parameter
1064 prerendering and the synthesis parameter matrix in general, splitting
1065 each audio fragment into subfragments now where each subfragment uses
1066 constant pitch and filter coefficients. The volume coefficient is
1067 linearly interpolated inside a subfragment, unless
1068 --disable-interpolate-volume is set.)
1069 - fine tuning of the EG modulation parameters
1070 - improved filter cutoff calculation by adding support for the
1071 following gig parameters: Cutoff freq (used when no cutoff
1072 controller is defined), Control invert, Minimum cutoff, Velocity
1073 curve and Velocity range. The keyboard tracking now scales
1074 cutoff frequency instead of resonance.
1075 - added support for gig parameter Resonance.
1076 - fixed bug in sysex handling (patch by Juan Linietsky)
1077 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1078 which can be overridden with --enable-global-attenuation
1079 - EG fixes: made the length of "attack hold" stage more
1080 accurate. Release stage can now start before attack stage
1081 ends. Cancel release didn't work when sustain was zero. Attack
1082 time now has a minimal value to prevent clicks.
1083 - fixed pitch changes larger than one octave
1084 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1085 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1086 all modes can be altered via standard GM messages, that is CC5 for
1087 altering portamento time, CC65 for enabling / disabling portamento
1088 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1089 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1090 parameter) and crossfade
1091 - added support for the "attenuation controller threshold" gig
1092 parameter
1093 - added smoothing of volume changes caused by control change
1094 messages
1095 - sample loop parameters are now taken from the DimensionRegion
1096 instead of the wave chunk
1097 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1098 not equal to a power of two
1099 - reimplementation of the filter algorithm. The new filter is more
1100 accurate and supports all gig filter types, including bandreject
1101 and lowpass turbo.
1102 - real support for 24 bit samples - samples are not truncated to
1103 16 bits anymore
1104 - support for aftertouch (channel pressure, not polyphonic
1105 aftertouch)
1106 - LFO1 behaviour fixed (dampening from max volume instead of
1107 amplifying from 0)
1108
1109 * LSCP server:
1110 - fixed application exit on broken pipe error (fixes bug #20)
1111 - fixed the notification messages delay due to lack of
1112 network activity (fixes bug #26)
1113 - fixed parser bug which occured on space(s) within device parameters
1114 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1115
1116 * audio driver:
1117 - added aRts audio output driver (by no means RT safe)
1118
1119 * MIDI driver:
1120 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1121 messages several times instead of once
1122 - API extension for MIDI drivers which already supply exact time stamps
1123 for events (i.e. for offline rendering based MIDI drivers)
1124 - added checks for bad MIDI data
1125
1126 * linuxsampler application:
1127 - show available sampler engine types on startup
1128
1129 * general changes:
1130 - support for muting sampler channels and solo mode of the same, two new
1131 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1132 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1133 introduced for this, the behavior is the same like on a mixer console
1134 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1135 --enable-process-muted-channels which can be used to enable the
1136 processing of muted channels.
1137 - support for sostenuto pedal
1138 - support for monitoring the total number of active voices
1139 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1140 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1141 - fixed some memory management errors
1142 - fixed some concurrency problems that could lead to crashes when
1143 LSCP commands were executed
1144 - fixed crash when instrument loading failed previously on the same
1145 sampler channel (fixes bug #36)
1146
1147 Version 0.3.3 (15 July 2005)
1148
1149 * packaging changes:
1150 - fixed compilation with gcc 4.0
1151
1152 * Gigasampler format engine:
1153 - LFO preprocessing was performed even though the respective LFO was
1154 disabled by the instrument patch (minor efficiency fix)
1155 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1156 for volume ramp downs in the same fragment (needed for current voice
1157 stealing implementation) then simply inform the user with a warning
1158 about possible click sounds and reduce the volume ramp down
1159 appropriately instead of cancelling the audio device connection
1160
1161 Version 0.3.2 (24 June 2005)
1162
1163 * packaging changes:
1164 - updated autotools build files to compile on OS X
1165 (conditional compilation of CoreMIDI and MidiShare drivers)
1166 - hand-crafted assembly optimization code can be disabled with
1167 './configure --disable-asm' (definitely not recommended)
1168 - fixed 'make dist' rule to include all necessary files
1169 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1170 (due to 'dist-bzip2' automake option)
1171
1172 * Gigasampler format engine:
1173 - support for the gig parameters for "release velocity response" curves
1174 - fine tuning of the EGADSR envelope
1175 - volume of release triggered samples now depends on note-on velocity,
1176 note length and gig parameter "release trigger decay" instead of
1177 note-off velocity.
1178 - revised voice stealing
1179 (fixes crash and endless loop caused by voice stealing)
1180 - don't reset scale tuning on instrument or audio output device change
1181 - handle key group conflicts right at the beginning of each fragment
1182 instead of when the respective voice is actually launched
1183 (fixes undefined behavior if stolen voices belonged to a key group -
1184 this case was followed by a "killed voice survived" error message)
1185 - fixed minor issue with null/silence samples
1186 (those stole voices even though they don't need a voice at all which
1187 resulted in "voice stealing didn't work out" messages)
1188 - don't reset volume, pan, pitch and MIDI controller values on
1189 instrument or audio output device change
1190
1191 * LSCP server:
1192 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1193 - fixed LSCP event "CHANNEL_INFO" notification
1194 (e.g. did not notify on volume changes or MIDI program change events)
1195
1196 * linuxsampler application:
1197 - added command line parameters --lscp-addr and --lscp-port to override
1198 default IP address and port of LSCP server
1199
1200 Version 0.3.1 (24 May 2005)
1201
1202 * initial release
