File size: 65839 byte(s)
* NKSP: Implemented built-in script function "inc()".
* NKSP: Implemented built-in script function "dec()".
* NKSP language fix: division expressions were evaluated too often.
* NKSP language fix: string concatenation operator was right
  associative instead of left (to right).
* Bumped version (2.0.0.svn15).

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

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

201 - fixed round robin and random dimensions for cases when number of
202 dimension zones is not a power of two
203 - made round robin use a counter for each region instead of each
204 key
205 - bugfix: pitch LFO controller "internal+aftertouch" was broken
206 - bugfix: filter keyboard tracking was broken
207 - filter performance fix (an unnecessary copy was made of the
208 filter parameters in each sub fragment)
209 - handle special case when pan parameter in gig file has max or
210 min value
211 - Exclusive Groups: don't ever stop voices of the same note,
212 doesn't sound naturally with a drumkit
213 - fixed EG1 modulation when attack or release is zero
214 - Fixed support for 'aftertouch' attenuation controller.
215 - Fixed crash that happened with velocity split sounds under certain
216 conditions (see also previous commit on libgig).

249 - added support for loop_mode=one_shot
250 - fixed playback of 16 bit wav files on big endian CPUs
251 - added support for Ogg Vorbis sample files
252 - use loop markers from sample file if loop_start and loop_end are
253 not set in sfz file

382 - added support for float and 32 bit sample files
383
384 * SoundFont format engine:
385 - Initial implementation (not usable yet)
386 - RT-safeness: avoid malloc in audio thread
387 - fixed a bug that could cause voice stealing to fail

390 - initial implementation of cutoff filter
391 - use linear decay and release for filter and pitch EG
392

404 - VST: made it possible to build the VST plugin for Mac
405 - AU: link AU plugin dynamically if --disable-shared isn't
406 specified

408 - VST bugfix: instrument loading hang and crashed the host when
409 the plugin was loaded a second time (#174)
410 - plugin bugfix: instrument loading hang when the plugin was
411 loaded a second time (this time it's for Linux and Mac, previous
412 similar fix was for Windows)
413 - thread safety fixes for the instrument loading thread

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

442 - MME: removed compiler warning
443 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
444 which allows to retrieve the list of CoreMIDI clients / ports and to connect
445 to them a la JACK, via the usual sampler APIs
446 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
447 the driver will automatically connect to other CoreMIDI clients' ports
448 (e.g. external MIDI devices being attached to the Mac)
449 - added support for MIDI note on velocity filter
450 - CoreMIDI: fixed memory deallocation error
451 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
452 virtual keyboards in frontends / instrument editors being stuck.

515 - Added support for auto completion by tab key.
516 - Show currently available auto completion while typing.
517 - Added support for browsing command history with up / down keys.

522 - Added support for built-in LSCP reference documentation, which will
523 automatically show the relevant LSCP reference section on screen as soon

575
576 * Bug fixes:

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

615 playing a note in a key group
616 - fixed erroneous error message piping in VoiceBase.h
617 (labelled "Disk stream not available in time")
618 - Update effects on sample rate & period size changes (to avoid
619 crashes and noise on such transitions).
620 - ignore missing LADSPA paths without ignoring valid LADSPA paths
621 (fixes #208)
622 - Fixed bug in LSCP grammar definition which caused a statement like
623 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
624 practically irrelevant, however it caused problems with the new LSCP
625 shell's auto completion feature).
626 - Fixed MIDI program change messages being ignored if quickly executed
627 after each other (fixes #231).
628
629 Version 1.0.0 (31 July 2009)
630
631 * packaging changes:
632 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
633 causing e.g. the libgig test to fail when
634 "./configure --disable-jack-driver" was used
635 (patch by Alexis Ballier)
636 - fixed compilation with gcc 4.3
637 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
638 - fixed configure so it detects x86_64 (#107)

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

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

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