Sat Jul 9 14:38:33 2016 UTC (3 years, 7 months ago) by schoenebeck
File size: 64465 byte(s)
* Implemented built-in instrument script function "change_vol()".
* Implemented built-in instrument script function "change_tune()".
* Implemented built-in instrument script function "change_pan()".
* Bumped version (2.0.0.svn11).

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
66 Version 2.0.0 (15 July 2015)
67

79 directories are separate
80 - Mac OS X: made it possible to specify plugin installation dir to
81 configure
82 - Mac OS X: Makefile fix for the install-strip target
83 - fixed compilation with gcc 4.7

94 - build fix: libsndfile compiler flags were missing in some
95 makefiles
96 - fix for building with bison 3.0 (#202)
97 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
98 on the process's main thread
99 - fixed build error on newer MinGW
100 - support building with older jack versions
101 - support building with spaces in vst sdk path
102 - enabled automake 'subdir-objects' option and moved external
103 source references (vst, au, asio) from makefiles to cpp files,
104 in order to get rid of warnings from automake 1.14
105
106 * general changes:
107 - Refactoring: moved the independent code from
108 the Gigasampler format engine to base classes
109 - command line option '--profile' is currently disabled, since the
110 respective profiling code is currently broken
111 - Introduced support for optional environment variable
112 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
113 where the sampler shall look for instrument editor plugins
114 (patch by Luis Garrido, slightly modified).
115 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
116 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
117 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
118 note (in this implementation of the sampler its simply hard routed to
119 the 1st effect send of the sampler channel, no matter what the actual
120 effect type is)
121 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
122 note (in this implementation of the sampler its simply hard routed to
123 the 2nd effect send of the sampler channel, no matter what the actual
124 effect type is)
125 - implemented support for internal LADSPA effects
126 - raised limit of program change queue from 100 to 512
127 (as suggested by Alex Stone)
128 - implemented sine LFO, pulse LFO and saw LFO
129 - experimental support for per voice equalization
130 - added command line option --exec-after-init
131 - Introduced new C++ API method:
132 EngineChannel::InstrumentFileName(int index)
133 allowing to retrieve the whole list of files used for the loaded
134 instrument on an engine channel (a.k.a. part). Some GigaStudio
135 instruments for example are splitted over several files like
136 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
137 - Added new C++ API method Sampler::GetGlobalMaxVoices().
138 - Added new C++ API method Sampler::GetGlobalMaxStreams().
139 - Added new C++ API method Sampler::SetGlobalMaxVoices().
140 - Added new C++ API method Sampler::SetGlobalMaxStreams().
141 - Various "const" and "restrict" optimizations.
142 - all engines: add pan CC value to instrument pan parameter before
143 applying panning, instead of using two separate pan functions in
144 series (#182)
145 - added a lock guard class for exception safe mutex handling and
146 used it everywhere appropriate
147 - Immediately apply scale tuning changes to active voices.
148 - Exposed scale tuning to C++ API (along to the already existing standard
149 SysEx way).
150 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
151 and broken for ppc64. (Seq_cst loads and stores are actually not
152 used in LS, so the bug wasn't noticable.)
153 - lsatomic.h: added ARMv7 support
154 - Added support for multiple MIDI input ports per sampler channel (and
155 added various new C++ methods for this new feature / design change, old
156 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
157 as deprecated but are still there and should provide full behavior
158 backward compatibility).
159 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
160 unsafe and caused compilation error with clang 2.x).
161 - Bugfix: only process the latest MIDI program change event.
162 - Introducing the LSCP shell, which provides convenient control of the
163 sampler from the command line by providing LSCP aware features.
164 - VirtualMidiDevice: Added support for program change.
165 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
166 - VirtualMidiDevice: Added support for pitch bend.
167 - Aftertouch: extended API to explicitly handle channel pressure and
168 polyphonic key pressure events (so far polyphonic pressure was not
169 supported at all, and channel pressure was rerouted as CC128 but not
170 used so far).
171 - Added initial support for real-time instrument scripts. The script VM
172 code is shared by all sampler engine implemementations, however only the
173 gig file format currently provides support for storing instrument scripts
174 (as LinuxSampler extension to the original GigaStudio 4 format).
175
176 * Gigasampler format engine:
177 - implemented the "round robin keyboard" dimension
178 - fixed round robin and random dimensions for cases when number of
179 dimension zones is not a power of two
180 - made round robin use a counter for each region instead of each
181 key
182 - bugfix: pitch LFO controller "internal+aftertouch" was broken
183 - bugfix: filter keyboard tracking was broken
184 - filter performance fix (an unnecessary copy was made of the
185 filter parameters in each sub fragment)
186 - handle special case when pan parameter in gig file has max or
187 min value
188 - Exclusive Groups: don't ever stop voices of the same note,
189 doesn't sound naturally with a drumkit
190 - fixed EG1 modulation when attack or release is zero
191 - Fixed support for 'aftertouch' attenuation controller.
192 - Fixed crash that happened with velocity split sounds under certain
193 conditions (see also previous commit on libgig).
194 - fixed behaviour of filter LFO
195
196 * SFZ format engine:
197 - Initial implementation (not usable yet)

205 - fixed error when unloading instrument with same sample used by
206 multiple regions
207 - added some opcode aliases, like loopmode for loop_mode, to be
208 more compatible

357 after each "#include", only after the main file is parsed
358 - bugfix: line numbers in error messages were wrong after "#include"
359 - added support for float and 32 bit sample files
360
361 * SoundFont format engine:
362 - Initial implementation (not usable yet)
363 - RT-safeness: avoid malloc in audio thread
364 - fixed a bug that could cause voice stealing to fail
365 - fine-tuned amplitude EG (by switching from gig to sfz EG)
366 - initial implementation of Vibrato LFO and Modulation LFO
367 - initial implementation of cutoff filter
368 - use linear decay and release for filter and pitch EG
369
370 * Host plugins (VST, AU, LV2, DSSI):
371 - AU bugfix: failed to destroy its audio/MIDI devices
372 - Listen to all interfaces on Mac OS X (INADDR_ANY)
373 - VST bugfix: If the host called resume() before and after
374 changing sample rate or block size, the number of channels was
375 incorrectly set to two. This caused silence in Cubase 5.
376 - save engine type (gig, sfz or sf2) in plugin state
377 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
378 64 bit Windows
379 - AU: changed number of output channels from one stereo to 16
380 stereo
381 - VST: made it possible to build the VST plugin for Mac
382 - AU: link AU plugin dynamically if --disable-shared isn't
383 specified
384 - LV2 "state" extension support (patch by David Robillard)
385 - VST bugfix: instrument loading hang and crashed the host when
386 the plugin was loaded a second time (#174)
387 - plugin bugfix: instrument loading hang when the plugin was
388 loaded a second time (this time it's for Linux and Mac, previous
389 similar fix was for Windows)
390 - thread safety fixes for the instrument loading thread
391 - LV2: use the new lv2 package if present
392 - VST: try to open Fantasia automatically on Linux and Mac too (on
393 Linux, the Fantasia jar should be placed in <prefix>/share/java)
394 - VST: fixed crashes on Linux Ardour and EnergyXT
395 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
396 port and audio channel routing for DSSI plugins are now visible.
397 - LV2: use urid and atom extensions instead of deprecated uri-map
398 and event
399 - LV2: lv2 package 1.0 is now required to build the LV2 plugin
400 - LV2: changed number of output channels to 16 stereo, just like
401 the VST and AU plugins
402 - LV2: fixed save/restore of SFZ state (patch by David Robillard)
403 - LV2: made LV2 plugin buildable on Windows and Mac
404 - VST: implemented retrieval and switching of programs using the
405 sampler's internal MIDI instrument mapping system
406
407 * Instrument editor interface:
408 - Changed instrument editor plugin interface, providing additional
409 informations like the EngineChannel for which the instrument editor was
410 spawned for. This allows the instrument editors to interact more actively
411 with the sampler.
412
413 * MIDI driver:
414 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
415 the ALSA sequencer client name
416 - removed limit of maximum amount of MIDI ports per MIDI device, since

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

592 playing a note in a key group
593 - fixed erroneous error message piping in VoiceBase.h
594 (labelled "Disk stream not available in time")

596 crashes and noise on such transitions).
597 - ignore missing LADSPA paths without ignoring valid LADSPA paths
598 (fixes #208)
599 - Fixed bug in LSCP grammar definition which caused a statement like
600 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
601 practically irrelevant, however it caused problems with the new LSCP
602 shell's auto completion feature).
603 - Fixed MIDI program change messages being ignored if quickly executed
604 after each other (fixes #231).
605
606 Version 1.0.0 (31 July 2009)
607
608 * packaging changes:
609 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

619 - minor fix in configure for mmsystem.h detection on MinGW
620 - Windows: look for editor plugins and Fantasia using base
621 directory of liblinuxsampler dll (look in the same directory and one
622 directory above)
623 - configure script fix: removed unconditional use of SSE
624 - fixed building with sqlite installed in a non-standard directory
625 - when cross-compiling, don't try to create instruments.db
626 - fix for new mingw-w64 version, which has usleep
627
628 * general changes:
629 - bugfix: on some POSIX systems instrument editor plugins refused to
630 load as we used a non-portable Linux specific struct field
631 (fixes bug #70, patch by Ronald Baljeu)
632 - fixed endless loop which occured when loading an instrument editor
633 plugin DLL on Windows systems failed
634 - fixed memory leaks that occurred when liblinuxsampler was unloaded
635 - optimized the SynchronizedConfig class so it doesn't wait
636 unnecessarily long after an update

638 events (e.g. to highlight the pressed keys on the virtual keyboard
639 of gigedit)
640 - added support for triggering notes by instrument editors (see above)
641 - be verbose on DLL load errors (on Linux)
642 - fixed di-harmonic triangle LFO implementation (this LFO implementation
643 is only used by very few systems, most pick the int math
644 implementation, which is usually faster)
645 - fixes for audio drivers with varying buffer sizes
646 - experimental support for running LinuxSampler as a DSSI, LV2 and
647 VST plugin
648 - notification events for stream/voice count statistics are now sent
649 only when there are actual changes

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

687 win64)
688 - VST: added support for sample rate and buffer size changes
689 - VST: close editor (Fantasia) when the VST is removed
690 - VST: avoid opening Fantasia more than once for each VST instance
691 - VST: export main function as "main" on Linux too (fix for
692 energyXT)
693 - VST: changed number of output channels from one stereo to 16
694 stereo
695 - added channel routing, fxsends and midi maps to the settings
696 stored in the plugin state
697 - performance optimization of AudioChannel::MixTo() and
698 AudioChannel::CopyTo() methods using GCC vector exensions
699 (if available)
700 - ASIO fixes: avoid initializing the device twice, avoid throwing
701 exception when getting parameters from a disconnected device
702
703 * MIDI driver:
704 - added JACK MIDI driver
705 - dispatch bank select as ordinary CC as well, the user might seriously
706 want to (mis)use it for some purpose ("fixed" in all current MIDI
707 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
708 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
709 CoreMidi or AU
710 - fixed mingw-w64 compilation error in MME driver
711 - made program change handling in MIDI thread real-time safe by
712 moving the logic to a non-RT thread
713 - fixed minor memory leak in ALSA driver
714
715 * instruments database:
716 - avoid time consuming samples scanning when adding instruments
717 to the instruments database

719 - Implemented option for adding instruments in separate directories
720 in the instruments database
721 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
722 - work-around for missing fnmatch function on Windows to make
723 instrument database compilable
724 - added instrument database support on Windows
725 works with both standalone mode and VST plugin.
726 the instruments DB file is located in
727 %USERPROFILE%\.linuxsampler\instruments.db which allows different
728 databases for each windows user
729 if no DB is present it automatically creates the .linuxsampler subdir
730 and then creates an empty DB
731 - fixed recursive import, which was broken on Windows
732
733 * Gigasampler format engine:
734 - fixed a memory leak that could happen when a channel was deleted
735 while notes were playing
736 - made it possible to load an instrument even if the audio thread
737 isn't running
738 - added partial support for the "Controller Triggered" MIDI rule,
739 enough for piano gigs with pedal noise samples
740 - minor fix: only mark FX sends as being modified if really the
741 respective FX send MIDI controller was used
742 - added support for GM global device volume SysEx message
743 (can be selected at compile time to either apply globally to the
744 whole sampler [default] or only to the sampler channels that are
745 connected to the respective MIDI input port the SysEx message arrived
746 on)
747 - bugfix: notes triggered at position 0 in the audio buffer were
748 sometimes wrongly killed in the same buffer, causing no sound to
749 be played
750 - added support for chromatic / drumkit mode Roland GS Sysex message
751 which is usally used to switch a part between chromatic sounds and
752 drumkit sounds (as opposed to their common default setting of MIDI
753 part 10 being a drumkit part and all other ones chromatic parts), in
754 LS however one can switch between the first 16 MIDI instrument maps
755 defined for the sampler
756 - made it possible to create multiple sample channels even if the
757 audio thread isn't running
758 - fixed crash when removing channel with active voices (#116)
759 - bugfix: on sample reference changes (instrument editor), only
760 un-cache the respective sample if it's really not used by any
761 sampler engine anymore
762 - re-cache samples in case they were changed by an instrument editor,
763 e.g. when a sample was added while playing (#82)
764 - fixed hanging notes which occured when note-off event had the exact
765 same time stamp as the voice's note-on event and occured both in the
766 same audio fragment cycle (fixes bug #112)
767 - added support for the "fine tune" and "pitch bend range"
768 instrument-level gig parameters
769 - fixed minor artifacts in pitch bend handling
770 - added support for GS Reset SysEx message
771 - allow gig files to use unlimited downward pitch shifting
772 - added a limit check for upward pitch shifting
773 - bugfix: sometimes, when playing a note twice fast, the second
774 note was silent
775 - fixed crash happening when a pitch bend event arrived at the
776 same time a new instrument was loading
777
778 * LSCP server:
779 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
780 react on MIDI data arriving on certain sampler channels (so far only
781 Note-On and Note-Off events are sent via this LSCP event)
782 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
783 react on MIDI data arriving on certain MIDI input devices (so far only
784 Note-On and Note-Off events are sent via this LSCP event)
785 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
786 SET DB_INSTRUMENT FILE_PATH
787 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
788 frontends to send MIDI messages to specific sampler channel
789 - added two additional fields to GET FILE INSTRUMENT INFO command -
790 KEY_BINDINGS and KEYSWITCH_BINDINGS
791 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
792 was incorrect
793 - Optimized the retrieval of the MIDI instrument mappings
794 - added new LSCP command "SET VOICES" to globally alter the maximum
795 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
796 be triggered respectively
797 - added new LSCP command "SET STREAMS" to globally alter the maximum
798 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
799 which will be triggered respectively
800 - bugfix: retry if "select" returns EINTR (this fixes a crash when
801 a gigedit file dialog is opened)
802 - close all connections when LSCPServer is deleted
803 - hard close of all sockets on exit
804 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
805 driver
806
807 * Bug fixes:
808 - fixed a crash which occurs when removing a sampler channel waiting
809 to start instrument loading after another channel
810 - fixed a crash which occurs when removing a sampler channel with
811 instrument loading in progress (bug #113)
812 - fixed termination caused by uncaught exception when adding MIDI
813 instrument with PERSISTENT load mode
814 - fixed possible iterator invalidations when resetting the sampler
815 - fixed memory leaks when issuing the following LSCP commands:
816 GET AUDIO_OUTPUT_DRIVER INFO
817 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
818 GET MIDI_INPUT_DRIVER INFO
819 GET MIDI_INPUT_DRIVER_PARAMETER INFO
820 - fixed possible compilation error when sqlite is not present
821 - fixed orphaned pointers when setting maximum voices limit (bug #118)
822 - fixed crash when changing the audio output device of a sampler
823 channel with loaded instrument and start playing notes
824 - fixed endless loop in Engine::SuspendAll() (bug #120)
825 - fixed a low-level atomic load function that was broken on 64-bit
826 PowerPC, which probably could cause crashes on that platform
827 - fixed a memory management error which could cause a crash when a
828 plugin was unloaded
829 - bugfix: two private structs had the same name, which could cause
830 problems if the linker chose the wrong constructor
831 - fixed low-level ConditionServer usage bug that caused lockups on
832 Windows
833
834
835 Version 0.5.1 (6 December 2007)
836
837 * packaging changes:
838 - added autoconf checks for pthread library
839 - added autoconf check for pthread bug found on certain NPTL-enabled
840 glibc versions (see Gentoo bug report #194076)
841 - added autoconf checks for MS Windows
842
843 * general changes:
844 - bugfix: the thread used by an editor plugin didn't die when the
845 editor closed
846 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
847 out all the space. operator--() did not apply size_mask after
848 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
849 order to avoid problems with the _NonVolatileReader functions.
850 - bugfix: Stream.h: added a missing divide by BytesPerSample in
851 GetWriteSpace(). Since this function is currently only used in
852 the stream's qsort() compare function, it didn't trigger any
853 bugs.
854 - Resampler.h, Synthesizer.h: cubic interpolation now works in
855 24bit mode too. Faster method to read 24bit words on little
856 endian machines (x86): replaced 3 byte reads + shifts with a 1
857 unaligned 32bit read and shift
858 - experimental support for MS Windows (MIDI input via MME, AUDIO
859 output via ASIO)
860 - made handling of SIGINT signal (Ctrl-C) a bit more robust
861 - support for monitoring the total number of active disk streams
862 (new LSCP commands: GET TOTAL_STREAM_COUNT,
863 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
864
865 * AUDIO driver:
866 - added Windows ASIO low latency audio driver
867
868 * MIDI driver:
869 - added MME Windows MIDI driver
870
871 * LSCP server:
872 - added support for Windows style path / filenames, however with
873 forward slash path separators instead of backslash
874 (i.e. "C:/foo/bar.gig")
875 - allow naughty liblscp to send non-string device parameters within
876 apostrophes as well
877 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
878 "LIST FILE INSTRUMENTS <file>" and
879 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
880 about an arbitrary instrument file on the system where the sampler is
881 running on
882
883 Version 0.5.0 (15 October 2007)
884
885 * packaging changes:
886 - config.h is not going to be installed along with liblinuxsampler's
887 API header files anymore
888 - only the API relevant header (and source) files will be exported to
889 the Doxygen API documentation (explicitly listed in Doxyfile.in)
890 - added completely new XCode project files for Mac OSX which is now
891 capable to execute our autoconf environment, thus no need anymore
892 to maintain the compile time configuration file (osx/version.h) for
893 OSX manually (patch by Toshi Nagata)
894 - fixed buggy boolean --enable-foo / --disable-foo configure script
895 parameters
896 - global.h now only covers global definitions that are needed for the
897 C++ API header files, all implementation internal global definitions
898 are now in global_private.h
899 - atomic.h is not exposed to the C++ API anymore
900 - no need to include config.h anymore for using LS's API header files
901 - fixed warnings in API doc generation
902
903 * general changes:
904 - replaced the old, confusing MIDI program change mechanism by a
905 flexible MIDI instrument mapper which allows to map arbitrary
906 (MIDI bank, MIDI program) pairs with arbitrary
907 (engine type, instrument file, file index) triplets which will be
908 loaded on the respective channel when such MIDI program change
909 messages arrive, beside that, each entry allows to define a life-time
910 strategy for the instrument, so the user can define whether the
911 instrument should i.e. be permanently loaded (to be able to switch
912 quickly among sounds) or i.e. loaded just on demand when the
913 respective program change arrives (to safe RAM space), as well as a
914 global volume factor for each entry, so the user can adjust the volume
915 dynamic of his mapped instrument collection without having to modify
916 the instrument files, also one can manage arbitrary amount of such
917 MIDI instrument maps and assign each sampler channel individually
918 a certain map, so that i.e. separation of normal instruments and
919 drumkits is possible
920 - new notification events for tracking changes to audio/MIDI devices,
921 MIDI instrument maps, MIDI instruments, FX sends, global volume.
922 - sampler was limited to load max. 200 instruments in the background
923 due to a constant size RingBuffer FIFO which is now replaced by a
924 dynamic (unlimited) size std::list FIFO
925 - added FX sends, these allow to route audio signals to arbitrary audio
926 output channels for being processed by external effect processors
927 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
928 controllers
929 - global (sampler wide) volume can now be controlled at runtime
930 - Implemented new, improved notification system
931 - fixed compilation errors regarding OSX
932 (patch by Toshi Nagata)
933 - implemented instruments database
934 - added support for escape sequences to the instruments database
935 - added highly experimental support for on-the-fly instrument editing
936 within the sampler's process (by using instrument editor plugins),
937 you'll notice the new "Registered instrument editors:" message on
938 startup, added a new LSCP command:
939 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
940 to spawn a matching instrument editor for the instrument on the
941 given sampler channel, the plugin path can be overridden at compile
942 time with ./configure --enable-plugin-dir=/some/dir
943 - added experimental code for synchronizing instrument editors hosted
944 in the sampler's process to safely edit instruments while playing
945 without a crash (hopefully) by either suspending single regions
946 wherever possible or if unavoidable whole engine(s)
947 - fixed several issues in fundamental "Thread" class: set scheduling
948 policy and priority on thread level, set a minimum stack size for
949 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
950 threads simply inherited properties of starting thread instead of
951 setting their own policy and priority
952 - minor fix in our automatic stack trace mechanism on crashes, the
953 main process did not wait for the stack trace process to finish
954 its output
955 - fixed some minor memory leaks
956 - reenabled assembly features support, at the moment only for
957 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
958 - minor assembly fix in x86 features detection (don't use the PIC
959 register, to avoid relocations in the text segment at runtime)
960 - POSIX callback functions of Thread.h are hidden
961
962 * MIDI driver:
963 - dispatch bank select (MSB and LSB) messages
964
965 * audio driver:
966 - the ALSA audio output driver parameters now reflect the correct
967 parameter value ranges for the respective selected sound card
968 (patch by Till Wimmer, a bit fixed and extended)
969
970 * Gigasampler format engine:
971 - if a filter is used and EG2 finishes before EG1, let the voice
972 die when EG2 has finished (this fixes a problem with clicks and
973 voice starvation for some gigs)
974 - playback is no longer disabled during instrument loading
975 - all notes playing on a channel that changes its instrument keep
976 playing with the old instrument until they get a note off
977 command
978 - EG fix: a release value of zero could cause noises or crash
979 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
980 - EG fine tuning: when attack is zero the EG starts at a level
981 above max sustain level, which means that there is a decay phase
982 even if sustain is 100%
983 - more EG fixes: the level could sometimes go below zero and cause
984 noises or crashes
985 - minor fix of EGDecay (patch by Toshi Nagata)
986 - fixed compiler error when --enable-override-filter-type was
987 supplied to the configure script (fixes #46)
988 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
989 instead of a fix value
990 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
991 127 (solo mode) only kill voices if the respective mode really
992 changed
993
994 * LSCP server:
995 - fixed compile time error for old Bison versions
996 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
997 - parser now supports extended ASCII character set
998 (up to ASCII code 255, i.e. includes now umlauts and accents)
999 - filename arguments in LSCP commands now allow to use escape
1000 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1001 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1002 code value like \xf2) (fixes bug #24)
1003 - the following LSCP commands now also support escape sequences for at
1004 least one of their text-based parameters (i.e. name, description):
1005 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1006 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1007 "SET DB_INSTRUMENT_DIRECTORY NAME",
1008 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1009 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1010 "FIND DB_INSTRUMENT_DIRECTORIES"
1011 - returns verbose syntax errors (line and column where syntax error
1012 occured, the unexpected character and the actually expected, possible
1013 character(s), the latter only if less than 5 possibilities)
1014 - made sure that LSCP syntax is not affected by gigedit locale
1015 settings
1016 - bugfix regarding strings parameter lists: all comma separated lists
1017 of strings were treated as being one string containing commas
1018 (fixes #57)
1019
1020 * Bug fixes:
1021 - fixed crash occurring on certain LSCP scripts (Bug 39)
1022 - another thread safety fix for lscp "load engine" and "set
1023 channel audio output device"
1024 - fixed a crash which occurs when reassigning the same engine
1025 on a sampler channel with connected MIDI device
1026 - fixed a crash which occurs when changing the number of ports of a MIDI
1027 device connected to a sampler channel to number less then or equal
1028 to the index of the port to which the sampler channel is connected.
1029 - The previous bindings were not been disconnected when altering
1030 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1031 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1032 - The active stream/voice count statistic was incorrect.
1033 - notification events were not been sent for some sampler
1034 channel changes
1035 - added default min and max values to restrict the number of allowed
1036 audio output channels and MIDI input ports
1037 - the connection to the PCM interface is now closed when destroying
1038 an audio output device
1039 - files with slash in their path or filename could not be loaded
1040
1041 * test cases:
1042 - updated and fixed (haven't been touched in a while)
1043
1044 Version 0.4.0 (24 November 2006)
1045
1046 * packaging changes:
1047 - changed deprecated copyright attribute to license; added ldconfig
1048 to post-(un)install steps; added devel package for liblinuxsampler;
1049 to linuxsampler.spec (RPM)
1050 - install necessary development header files for allowing 3rd party
1051 applications to link against liblinuxsampler
1052 - liblinuxsampler's API documentation can be generated with 'make docs'
1053 (Doxygen required)
1054 - added benchmark to automatically detect the best triangle LFO
1055 implementation (currently either an integer math solution or a
1056 di-harmonic approximation), automatic detection can be overriden
1057 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1058 configure script argument though (mandatory for cross-compilation)
1059 - do not automatically pick optimized gcc flags if the user already
1060 provided some on his own (as CXXFLAGS)
1061 - added compile time option to disable processing of All-Notes-Off MIDI
1062 messages
1063 - added compile time options to allow disabling the various audio and
1064 MIDI drivers
1065 - fixed automatic GCC CPU switch detection on PPC
1066 (patch by Ebrahim Mayat)
1067
1068 * Gigasampler format engine:
1069 - extensive synthesis optimization
1070 (reimplementation of EGs and LFO(s), removed synthesis parameter
1071 prerendering and the synthesis parameter matrix in general, splitting
1072 each audio fragment into subfragments now where each subfragment uses
1073 constant pitch and filter coefficients. The volume coefficient is
1074 linearly interpolated inside a subfragment, unless
1075 --disable-interpolate-volume is set.)
1076 - fine tuning of the EG modulation parameters
1077 - improved filter cutoff calculation by adding support for the
1078 following gig parameters: Cutoff freq (used when no cutoff
1079 controller is defined), Control invert, Minimum cutoff, Velocity
1080 curve and Velocity range. The keyboard tracking now scales
1081 cutoff frequency instead of resonance.
1082 - added support for gig parameter Resonance.
1083 - fixed bug in sysex handling (patch by Juan Linietsky)
1084 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1085 which can be overridden with --enable-global-attenuation
1086 - EG fixes: made the length of "attack hold" stage more
1087 accurate. Release stage can now start before attack stage
1088 ends. Cancel release didn't work when sustain was zero. Attack
1089 time now has a minimal value to prevent clicks.
1090 - fixed pitch changes larger than one octave
1091 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1092 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1093 all modes can be altered via standard GM messages, that is CC5 for
1094 altering portamento time, CC65 for enabling / disabling portamento
1095 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1096 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1097 parameter) and crossfade
1098 - added support for the "attenuation controller threshold" gig
1099 parameter
1100 - added smoothing of volume changes caused by control change
1101 messages
1102 - sample loop parameters are now taken from the DimensionRegion
1103 instead of the wave chunk
1104 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1105 not equal to a power of two
1106 - reimplementation of the filter algorithm. The new filter is more
1107 accurate and supports all gig filter types, including bandreject
1108 and lowpass turbo.
1109 - real support for 24 bit samples - samples are not truncated to
1110 16 bits anymore
1111 - support for aftertouch (channel pressure, not polyphonic
1112 aftertouch)
1113 - LFO1 behaviour fixed (dampening from max volume instead of
1114 amplifying from 0)
1115
1116 * LSCP server:
1117 - fixed application exit on broken pipe error (fixes bug #20)
1118 - fixed the notification messages delay due to lack of
1119 network activity (fixes bug #26)
1120 - fixed parser bug which occured on space(s) within device parameters
1121 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1122
1123 * audio driver:
1124 - added aRts audio output driver (by no means RT safe)
1125
1126 * MIDI driver:
1127 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1128 messages several times instead of once
1129 - API extension for MIDI drivers which already supply exact time stamps
1130 for events (i.e. for offline rendering based MIDI drivers)
1131 - added checks for bad MIDI data
1132
1133 * linuxsampler application:
1134 - show available sampler engine types on startup
1135
1136 * general changes:
1137 - support for muting sampler channels and solo mode of the same, two new
1138 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1139 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1140 introduced for this, the behavior is the same like on a mixer console
1141 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1142 --enable-process-muted-channels which can be used to enable the
1143 processing of muted channels.
1144 - support for sostenuto pedal
1145 - support for monitoring the total number of active voices
1146 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1147 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1148 - fixed some memory management errors
1149 - fixed some concurrency problems that could lead to crashes when
1150 LSCP commands were executed
1151 - fixed crash when instrument loading failed previously on the same
1152 sampler channel (fixes bug #36)
1153
1154 Version 0.3.3 (15 July 2005)
1155
1156 * packaging changes:
1157 - fixed compilation with gcc 4.0
1158
1159 * Gigasampler format engine:
1160 - LFO preprocessing was performed even though the respective LFO was
1161 disabled by the instrument patch (minor efficiency fix)
1162 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1163 for volume ramp downs in the same fragment (needed for current voice
1164 stealing implementation) then simply inform the user with a warning
1165 about possible click sounds and reduce the volume ramp down
1166 appropriately instead of cancelling the audio device connection
1167
1168 Version 0.3.2 (24 June 2005)
1169
1170 * packaging changes:
1171 - updated autotools build files to compile on OS X
1172 (conditional compilation of CoreMIDI and MidiShare drivers)
1173 - hand-crafted assembly optimization code can be disabled with
1174 './configure --disable-asm' (definitely not recommended)
1175 - fixed 'make dist' rule to include all necessary files
1176 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1177 (due to 'dist-bzip2' automake option)
1178
1179 * Gigasampler format engine:
1180 - support for the gig parameters for "release velocity response" curves
1181 - fine tuning of the EGADSR envelope
1182 - volume of release triggered samples now depends on note-on velocity,
1183 note length and gig parameter "release trigger decay" instead of
1184 note-off velocity.
1185 - revised voice stealing
1186 (fixes crash and endless loop caused by voice stealing)
1187 - don't reset scale tuning on instrument or audio output device change
1188 - handle key group conflicts right at the beginning of each fragment
1189 instead of when the respective voice is actually launched
1190 (fixes undefined behavior if stolen voices belonged to a key group -
1191 this case was followed by a "killed voice survived" error message)
1192 - fixed minor issue with null/silence samples
1193 (those stole voices even though they don't need a voice at all which
1194 resulted in "voice stealing didn't work out" messages)
1195 - don't reset volume, pan, pitch and MIDI controller values on
1196 instrument or audio output device change
1197
1198 * LSCP server:
1199 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1200 - fixed LSCP event "CHANNEL_INFO" notification
1201 (e.g. did not notify on volume changes or MIDI program change events)
1202
1203 * linuxsampler application:
1204 - added command line parameters --lscp-addr and --lscp-port to override
1205 default IP address and port of LSCP server
1206
1207 Version 0.3.1 (24 May 2005)
1208
1209 * initial release
