File size: 65308 byte(s)
* Fixed behavior of built-in instrument script functions play_note()
  and note_off(), which must be distinguished engine internally
  from "real" MIDI note on/off events in order to avoid
  misbehaviors like hanging notes.
* Bumped version (2.0.0.svn13).

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
80 Version 2.0.0 (15 July 2015)
81

102 - fixed linkage error when building with
103 LDFLAGS="-Wl,--no-undefined" (#190)
104 - fixed compilation with Clang 3.2
105 - removed usage of deprecated Automake variable INCLUDES
106 - fixed building with C++11

109 makefiles
110 - fix for building with bison 3.0 (#202)
111 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
112 on the process's main thread
113 - fixed build error on newer MinGW
114 - support building with older jack versions
115 - support building with spaces in vst sdk path
116 - enabled automake 'subdir-objects' option and moved external
117 source references (vst, au, asio) from makefiles to cpp files,
118 in order to get rid of warnings from automake 1.14
119
120 * general changes:
121 - Refactoring: moved the independent code from
122 the Gigasampler format engine to base classes
123 - command line option '--profile' is currently disabled, since the
124 respective profiling code is currently broken
125 - Introduced support for optional environment variable
126 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
127 where the sampler shall look for instrument editor plugins
128 (patch by Luis Garrido, slightly modified).
129 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
130 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
131 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
132 note (in this implementation of the sampler its simply hard routed to
133 the 1st effect send of the sampler channel, no matter what the actual
134 effect type is)
135 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
136 note (in this implementation of the sampler its simply hard routed to
137 the 2nd effect send of the sampler channel, no matter what the actual
138 effect type is)
139 - implemented support for internal LADSPA effects
140 - raised limit of program change queue from 100 to 512
141 (as suggested by Alex Stone)
142 - implemented sine LFO, pulse LFO and saw LFO
143 - experimental support for per voice equalization
144 - added command line option --exec-after-init
145 - Introduced new C++ API method:
146 EngineChannel::InstrumentFileName(int index)
147 allowing to retrieve the whole list of files used for the loaded
148 instrument on an engine channel (a.k.a. part). Some GigaStudio
149 instruments for example are splitted over several files like
150 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
151 - Added new C++ API method Sampler::GetGlobalMaxVoices().
152 - Added new C++ API method Sampler::GetGlobalMaxStreams().
153 - Added new C++ API method Sampler::SetGlobalMaxVoices().
154 - Added new C++ API method Sampler::SetGlobalMaxStreams().
155 - Various "const" and "restrict" optimizations.
156 - all engines: add pan CC value to instrument pan parameter before
157 applying panning, instead of using two separate pan functions in
158 series (#182)
159 - added a lock guard class for exception safe mutex handling and
160 used it everywhere appropriate
161 - Immediately apply scale tuning changes to active voices.
162 - Exposed scale tuning to C++ API (along to the already existing standard
163 SysEx way).
164 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
165 and broken for ppc64. (Seq_cst loads and stores are actually not
166 used in LS, so the bug wasn't noticable.)
167 - lsatomic.h: added ARMv7 support
168 - Added support for multiple MIDI input ports per sampler channel (and
169 added various new C++ methods for this new feature / design change, old
170 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
171 as deprecated but are still there and should provide full behavior
172 backward compatibility).
173 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
174 unsafe and caused compilation error with clang 2.x).
175 - Bugfix: only process the latest MIDI program change event.
176 - Introducing the LSCP shell, which provides convenient control of the
177 sampler from the command line by providing LSCP aware features.
178 - VirtualMidiDevice: Added support for program change.
179 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
180 - VirtualMidiDevice: Added support for pitch bend.
181 - Aftertouch: extended API to explicitly handle channel pressure and
182 polyphonic key pressure events (so far polyphonic pressure was not
183 supported at all, and channel pressure was rerouted as CC128 but not
184 used so far).
185 - Added initial support for real-time instrument scripts. The script VM
186 code is shared by all sampler engine implemementations, however only the
187 gig file format currently provides support for storing instrument scripts
188 (as LinuxSampler extension to the original GigaStudio 4 format).
189
190 * Gigasampler format engine:
191 - implemented the "round robin keyboard" dimension
192 - fixed round robin and random dimensions for cases when number of
193 dimension zones is not a power of two
194 - made round robin use a counter for each region instead of each
195 key
196 - bugfix: pitch LFO controller "internal+aftertouch" was broken
197 - bugfix: filter keyboard tracking was broken
198 - filter performance fix (an unnecessary copy was made of the
199 filter parameters in each sub fragment)
200 - handle special case when pan parameter in gig file has max or
201 min value
202 - Exclusive Groups: don't ever stop voices of the same note,
203 doesn't sound naturally with a drumkit
204 - fixed EG1 modulation when attack or release is zero
205 - Fixed support for 'aftertouch' attenuation controller.
206 - Fixed crash that happened with velocity split sounds under certain
207 conditions (see also previous commit on libgig).
208 - fixed behaviour of filter LFO
209
210 * SFZ format engine:

372 - bugfix: line numbers in error messages were wrong after "#include"
373 - added support for float and 32 bit sample files
374
375 * SoundFont format engine:
376 - Initial implementation (not usable yet)
377 - RT-safeness: avoid malloc in audio thread

381 - initial implementation of cutoff filter
382 - use linear decay and release for filter and pitch EG
383
384 * Host plugins (VST, AU, LV2, DSSI):
385 - AU bugfix: failed to destroy its audio/MIDI devices
386 - Listen to all interfaces on Mac OS X (INADDR_ANY)
387 - VST bugfix: If the host called resume() before and after
388 changing sample rate or block size, the number of channels was
389 incorrectly set to two. This caused silence in Cubase 5.
390 - save engine type (gig, sfz or sf2) in plugin state
391 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
392 64 bit Windows

397 specified
398 - LV2 "state" extension support (patch by David Robillard)
399 - VST bugfix: instrument loading hang and crashed the host when
400 the plugin was loaded a second time (#174)
401 - plugin bugfix: instrument loading hang when the plugin was
402 loaded a second time (this time it's for Linux and Mac, previous
403 similar fix was for Windows)
404 - thread safety fixes for the instrument loading thread
405 - LV2: use the new lv2 package if present
406 - VST: try to open Fantasia automatically on Linux and Mac too (on
407 Linux, the Fantasia jar should be placed in <prefix>/share/java)
408 - VST: fixed crashes on Linux Ardour and EnergyXT
409 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
410 port and audio channel routing for DSSI plugins are now visible.
411 - LV2: use urid and atom extensions instead of deprecated uri-map
412 and event
413 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

420
421 * Instrument editor interface:
422 - Changed instrument editor plugin interface, providing additional
423 informations like the EngineChannel for which the instrument editor was
424 spawned for. This allows the instrument editors to interact more actively
425 with the sampler.
426
427 * MIDI driver:
428 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
429 the ALSA sequencer client name

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

446 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
447 - MME bugfix: driver wasn't closed properly
448 - CoreMIDI: automatically connect to all input sources by default (driver
449 parameter "AUTO_BIND").

505 - Added support for auto correction of obvious and trivial syntax mistakes.
506 - Added support for auto completion by tab key.
507 - Show currently available auto completion while typing.
508 - Added support for browsing command history with up / down keys.
509 - Show all possible next symbols immediately right to the current command

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

566
567 * Bug fixes:

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

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

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

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

733 - Implemented option for adding instruments in separate directories
734 in the instruments database
735 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
736 - work-around for missing fnmatch function on Windows to make
737 instrument database compilable
738 - added instrument database support on Windows
739 works with both standalone mode and VST plugin.
740 the instruments DB file is located in
741 %USERPROFILE%\.linuxsampler\instruments.db which allows different
742 databases for each windows user
743 if no DB is present it automatically creates the .linuxsampler subdir
744 and then creates an empty DB
745 - fixed recursive import, which was broken on Windows
746
747 * Gigasampler format engine:
748 - fixed a memory leak that could happen when a channel was deleted
749 while notes were playing
750 - made it possible to load an instrument even if the audio thread
751 isn't running
752 - added partial support for the "Controller Triggered" MIDI rule,
753 enough for piano gigs with pedal noise samples
754 - minor fix: only mark FX sends as being modified if really the
755 respective FX send MIDI controller was used
756 - added support for GM global device volume SysEx message
757 (can be selected at compile time to either apply globally to the
758 whole sampler [default] or only to the sampler channels that are
759 connected to the respective MIDI input port the SysEx message arrived
760 on)
761 - bugfix: notes triggered at position 0 in the audio buffer were
762 sometimes wrongly killed in the same buffer, causing no sound to
763 be played
764 - added support for chromatic / drumkit mode Roland GS Sysex message
765 which is usally used to switch a part between chromatic sounds and
766 drumkit sounds (as opposed to their common default setting of MIDI
767 part 10 being a drumkit part and all other ones chromatic parts), in
768 LS however one can switch between the first 16 MIDI instrument maps
769 defined for the sampler
770 - made it possible to create multiple sample channels even if the
771 audio thread isn't running
772 - fixed crash when removing channel with active voices (#116)
773 - bugfix: on sample reference changes (instrument editor), only
774 un-cache the respective sample if it's really not used by any
775 sampler engine anymore
776 - re-cache samples in case they were changed by an instrument editor,
777 e.g. when a sample was added while playing (#82)
778 - fixed hanging notes which occured when note-off event had the exact
779 same time stamp as the voice's note-on event and occured both in the
780 same audio fragment cycle (fixes bug #112)
781 - added support for the "fine tune" and "pitch bend range"
782 instrument-level gig parameters
783 - fixed minor artifacts in pitch bend handling
784 - added support for GS Reset SysEx message
785 - allow gig files to use unlimited downward pitch shifting
786 - added a limit check for upward pitch shifting
787 - bugfix: sometimes, when playing a note twice fast, the second
788 note was silent
789 - fixed crash happening when a pitch bend event arrived at the
790 same time a new instrument was loading
791
792 * LSCP server:
793 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
794 react on MIDI data arriving on certain sampler channels (so far only
795 Note-On and Note-Off events are sent via this LSCP event)
796 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
797 react on MIDI data arriving on certain MIDI input devices (so far only
798 Note-On and Note-Off events are sent via this LSCP event)
799 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
800 SET DB_INSTRUMENT FILE_PATH
801 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
802 frontends to send MIDI messages to specific sampler channel
803 - added two additional fields to GET FILE INSTRUMENT INFO command -
804 KEY_BINDINGS and KEYSWITCH_BINDINGS
805 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
806 was incorrect
807 - Optimized the retrieval of the MIDI instrument mappings
808 - added new LSCP command "SET VOICES" to globally alter the maximum
809 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
810 be triggered respectively
811 - added new LSCP command "SET STREAMS" to globally alter the maximum
812 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
813 which will be triggered respectively
814 - bugfix: retry if "select" returns EINTR (this fixes a crash when
815 a gigedit file dialog is opened)
816 - close all connections when LSCPServer is deleted
817 - hard close of all sockets on exit
818 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
819 driver
820
821 * Bug fixes:
822 - fixed a crash which occurs when removing a sampler channel waiting
823 to start instrument loading after another channel
824 - fixed a crash which occurs when removing a sampler channel with
825 instrument loading in progress (bug #113)
826 - fixed termination caused by uncaught exception when adding MIDI
827 instrument with PERSISTENT load mode
828 - fixed possible iterator invalidations when resetting the sampler
829 - fixed memory leaks when issuing the following LSCP commands:
830 GET AUDIO_OUTPUT_DRIVER INFO
831 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
832 GET MIDI_INPUT_DRIVER INFO
833 GET MIDI_INPUT_DRIVER_PARAMETER INFO
834 - fixed possible compilation error when sqlite is not present
835 - fixed orphaned pointers when setting maximum voices limit (bug #118)
836 - fixed crash when changing the audio output device of a sampler
837 channel with loaded instrument and start playing notes
838 - fixed endless loop in Engine::SuspendAll() (bug #120)
839 - fixed a low-level atomic load function that was broken on 64-bit
840 PowerPC, which probably could cause crashes on that platform
841 - fixed a memory management error which could cause a crash when a
842 plugin was unloaded
843 - bugfix: two private structs had the same name, which could cause
844 problems if the linker chose the wrong constructor
845 - fixed low-level ConditionServer usage bug that caused lockups on
846 Windows
847
848
849 Version 0.5.1 (6 December 2007)
850
851 * packaging changes:
852 - added autoconf checks for pthread library
853 - added autoconf check for pthread bug found on certain NPTL-enabled
854 glibc versions (see Gentoo bug report #194076)
855 - added autoconf checks for MS Windows
856
857 * general changes:
858 - bugfix: the thread used by an editor plugin didn't die when the
859 editor closed
860 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
861 out all the space. operator--() did not apply size_mask after
862 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
863 order to avoid problems with the _NonVolatileReader functions.
864 - bugfix: Stream.h: added a missing divide by BytesPerSample in
865 GetWriteSpace(). Since this function is currently only used in
866 the stream's qsort() compare function, it didn't trigger any
867 bugs.
868 - Resampler.h, Synthesizer.h: cubic interpolation now works in
869 24bit mode too. Faster method to read 24bit words on little
870 endian machines (x86): replaced 3 byte reads + shifts with a 1
871 unaligned 32bit read and shift
872 - experimental support for MS Windows (MIDI input via MME, AUDIO
873 output via ASIO)
874 - made handling of SIGINT signal (Ctrl-C) a bit more robust
875 - support for monitoring the total number of active disk streams
876 (new LSCP commands: GET TOTAL_STREAM_COUNT,
877 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
878
879 * AUDIO driver:
880 - added Windows ASIO low latency audio driver
881
882 * MIDI driver:
883 - added MME Windows MIDI driver
884
885 * LSCP server:
886 - added support for Windows style path / filenames, however with
887 forward slash path separators instead of backslash
888 (i.e. "C:/foo/bar.gig")
889 - allow naughty liblscp to send non-string device parameters within
890 apostrophes as well
891 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
892 "LIST FILE INSTRUMENTS <file>" and
893 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
894 about an arbitrary instrument file on the system where the sampler is
895 running on
896
897 Version 0.5.0 (15 October 2007)
898
899 * packaging changes:
900 - config.h is not going to be installed along with liblinuxsampler's
901 API header files anymore
902 - only the API relevant header (and source) files will be exported to
903 the Doxygen API documentation (explicitly listed in Doxyfile.in)
904 - added completely new XCode project files for Mac OSX which is now
905 capable to execute our autoconf environment, thus no need anymore
906 to maintain the compile time configuration file (osx/version.h) for
907 OSX manually (patch by Toshi Nagata)
908 - fixed buggy boolean --enable-foo / --disable-foo configure script
909 parameters
910 - global.h now only covers global definitions that are needed for the
911 C++ API header files, all implementation internal global definitions
912 are now in global_private.h
913 - atomic.h is not exposed to the C++ API anymore
914 - no need to include config.h anymore for using LS's API header files
915 - fixed warnings in API doc generation
916
917 * general changes:
918 - replaced the old, confusing MIDI program change mechanism by a
919 flexible MIDI instrument mapper which allows to map arbitrary
920 (MIDI bank, MIDI program) pairs with arbitrary
921 (engine type, instrument file, file index) triplets which will be
922 loaded on the respective channel when such MIDI program change
923 messages arrive, beside that, each entry allows to define a life-time
924 strategy for the instrument, so the user can define whether the
925 instrument should i.e. be permanently loaded (to be able to switch
926 quickly among sounds) or i.e. loaded just on demand when the
927 respective program change arrives (to safe RAM space), as well as a
928 global volume factor for each entry, so the user can adjust the volume
929 dynamic of his mapped instrument collection without having to modify
930 the instrument files, also one can manage arbitrary amount of such
931 MIDI instrument maps and assign each sampler channel individually
932 a certain map, so that i.e. separation of normal instruments and
933 drumkits is possible
934 - new notification events for tracking changes to audio/MIDI devices,
935 MIDI instrument maps, MIDI instruments, FX sends, global volume.
936 - sampler was limited to load max. 200 instruments in the background
937 due to a constant size RingBuffer FIFO which is now replaced by a
938 dynamic (unlimited) size std::list FIFO
939 - added FX sends, these allow to route audio signals to arbitrary audio
940 output channels for being processed by external effect processors
941 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
942 controllers
943 - global (sampler wide) volume can now be controlled at runtime
944 - Implemented new, improved notification system
945 - fixed compilation errors regarding OSX
946 (patch by Toshi Nagata)
947 - implemented instruments database
948 - added support for escape sequences to the instruments database
949 - added highly experimental support for on-the-fly instrument editing
950 within the sampler's process (by using instrument editor plugins),
951 you'll notice the new "Registered instrument editors:" message on
952 startup, added a new LSCP command:
953 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
954 to spawn a matching instrument editor for the instrument on the
955 given sampler channel, the plugin path can be overridden at compile
956 time with ./configure --enable-plugin-dir=/some/dir
957 - added experimental code for synchronizing instrument editors hosted
958 in the sampler's process to safely edit instruments while playing
959 without a crash (hopefully) by either suspending single regions
960 wherever possible or if unavoidable whole engine(s)
961 - fixed several issues in fundamental "Thread" class: set scheduling
962 policy and priority on thread level, set a minimum stack size for
963 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
964 threads simply inherited properties of starting thread instead of
965 setting their own policy and priority
966 - minor fix in our automatic stack trace mechanism on crashes, the
967 main process did not wait for the stack trace process to finish
968 its output
969 - fixed some minor memory leaks
970 - reenabled assembly features support, at the moment only for
971 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
972 - minor assembly fix in x86 features detection (don't use the PIC
973 register, to avoid relocations in the text segment at runtime)
974 - POSIX callback functions of Thread.h are hidden
975
976 * MIDI driver:
977 - dispatch bank select (MSB and LSB) messages
978
979 * audio driver:
980 - the ALSA audio output driver parameters now reflect the correct
981 parameter value ranges for the respective selected sound card
982 (patch by Till Wimmer, a bit fixed and extended)
983
984 * Gigasampler format engine:
985 - if a filter is used and EG2 finishes before EG1, let the voice
986 die when EG2 has finished (this fixes a problem with clicks and
987 voice starvation for some gigs)
988 - playback is no longer disabled during instrument loading
989 - all notes playing on a channel that changes its instrument keep
990 playing with the old instrument until they get a note off
991 command
992 - EG fix: a release value of zero could cause noises or crash
993 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
994 - EG fine tuning: when attack is zero the EG starts at a level
995 above max sustain level, which means that there is a decay phase
996 even if sustain is 100%
997 - more EG fixes: the level could sometimes go below zero and cause
998 noises or crashes
999 - minor fix of EGDecay (patch by Toshi Nagata)
1000 - fixed compiler error when --enable-override-filter-type was
1001 supplied to the configure script (fixes #46)
1002 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1003 instead of a fix value
1004 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1005 127 (solo mode) only kill voices if the respective mode really
1006 changed
1007
1008 * LSCP server:
1009 - fixed compile time error for old Bison versions
1010 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1011 - parser now supports extended ASCII character set
1012 (up to ASCII code 255, i.e. includes now umlauts and accents)
1013 - filename arguments in LSCP commands now allow to use escape
1014 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1015 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1016 code value like \xf2) (fixes bug #24)
1017 - the following LSCP commands now also support escape sequences for at
1018 least one of their text-based parameters (i.e. name, description):
1019 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1020 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1021 "SET DB_INSTRUMENT_DIRECTORY NAME",
1022 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1023 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1024 "FIND DB_INSTRUMENT_DIRECTORIES"
1025 - returns verbose syntax errors (line and column where syntax error
1026 occured, the unexpected character and the actually expected, possible
1027 character(s), the latter only if less than 5 possibilities)
1028 - made sure that LSCP syntax is not affected by gigedit locale
1029 settings
1030 - bugfix regarding strings parameter lists: all comma separated lists
1031 of strings were treated as being one string containing commas
1032 (fixes #57)
1033
1034 * Bug fixes:
1035 - fixed crash occurring on certain LSCP scripts (Bug 39)
1036 - another thread safety fix for lscp "load engine" and "set
1037 channel audio output device"
1038 - fixed a crash which occurs when reassigning the same engine
1039 on a sampler channel with connected MIDI device
1040 - fixed a crash which occurs when changing the number of ports of a MIDI
1041 device connected to a sampler channel to number less then or equal
1042 to the index of the port to which the sampler channel is connected.
1043 - The previous bindings were not been disconnected when altering
1044 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1045 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1046 - The active stream/voice count statistic was incorrect.
1047 - notification events were not been sent for some sampler
1048 channel changes
1049 - added default min and max values to restrict the number of allowed
1050 audio output channels and MIDI input ports
1051 - the connection to the PCM interface is now closed when destroying
1052 an audio output device
1053 - files with slash in their path or filename could not be loaded
1054
1055 * test cases:
1056 - updated and fixed (haven't been touched in a while)
1057
1058 Version 0.4.0 (24 November 2006)
1059
1060 * packaging changes:
1061 - changed deprecated copyright attribute to license; added ldconfig
1062 to post-(un)install steps; added devel package for liblinuxsampler;
1063 to linuxsampler.spec (RPM)
1064 - install necessary development header files for allowing 3rd party
1065 applications to link against liblinuxsampler
1066 - liblinuxsampler's API documentation can be generated with 'make docs'
1067 (Doxygen required)
1068 - added benchmark to automatically detect the best triangle LFO
1069 implementation (currently either an integer math solution or a
1070 di-harmonic approximation), automatic detection can be overriden
1071 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1072 configure script argument though (mandatory for cross-compilation)
1073 - do not automatically pick optimized gcc flags if the user already
1074 provided some on his own (as CXXFLAGS)
1075 - added compile time option to disable processing of All-Notes-Off MIDI
1076 messages
1077 - added compile time options to allow disabling the various audio and
1078 MIDI drivers
1079 - fixed automatic GCC CPU switch detection on PPC
1080 (patch by Ebrahim Mayat)
1081
1082 * Gigasampler format engine:
1083 - extensive synthesis optimization
1084 (reimplementation of EGs and LFO(s), removed synthesis parameter
1085 prerendering and the synthesis parameter matrix in general, splitting
1086 each audio fragment into subfragments now where each subfragment uses
1087 constant pitch and filter coefficients. The volume coefficient is
1088 linearly interpolated inside a subfragment, unless
1089 --disable-interpolate-volume is set.)
1090 - fine tuning of the EG modulation parameters
1091 - improved filter cutoff calculation by adding support for the
1092 following gig parameters: Cutoff freq (used when no cutoff
1093 controller is defined), Control invert, Minimum cutoff, Velocity
1094 curve and Velocity range. The keyboard tracking now scales
1095 cutoff frequency instead of resonance.
1096 - added support for gig parameter Resonance.
1097 - fixed bug in sysex handling (patch by Juan Linietsky)
1098 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1099 which can be overridden with --enable-global-attenuation
1100 - EG fixes: made the length of "attack hold" stage more
1101 accurate. Release stage can now start before attack stage
1102 ends. Cancel release didn't work when sustain was zero. Attack
1103 time now has a minimal value to prevent clicks.
1104 - fixed pitch changes larger than one octave
1105 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1106 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1107 all modes can be altered via standard GM messages, that is CC5 for
1108 altering portamento time, CC65 for enabling / disabling portamento
1109 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1110 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1111 parameter) and crossfade
1112 - added support for the "attenuation controller threshold" gig
1113 parameter
1114 - added smoothing of volume changes caused by control change
1115 messages
1116 - sample loop parameters are now taken from the DimensionRegion
1117 instead of the wave chunk
1118 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1119 not equal to a power of two
1120 - reimplementation of the filter algorithm. The new filter is more
1121 accurate and supports all gig filter types, including bandreject
1122 and lowpass turbo.
1123 - real support for 24 bit samples - samples are not truncated to
1124 16 bits anymore
1125 - support for aftertouch (channel pressure, not polyphonic
1126 aftertouch)
1127 - LFO1 behaviour fixed (dampening from max volume instead of
1128 amplifying from 0)
1129
1130 * LSCP server:
1131 - fixed application exit on broken pipe error (fixes bug #20)
1132 - fixed the notification messages delay due to lack of
1133 network activity (fixes bug #26)
1134 - fixed parser bug which occured on space(s) within device parameters
1135 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1136
1137 * audio driver:
1138 - added aRts audio output driver (by no means RT safe)
1139
1140 * MIDI driver:
1141 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1142 messages several times instead of once
1143 - API extension for MIDI drivers which already supply exact time stamps
1144 for events (i.e. for offline rendering based MIDI drivers)
1145 - added checks for bad MIDI data
1146
1147 * linuxsampler application:
1148 - show available sampler engine types on startup
1149
1150 * general changes:
1151 - support for muting sampler channels and solo mode of the same, two new
1152 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1153 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1154 introduced for this, the behavior is the same like on a mixer console
1155 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1156 --enable-process-muted-channels which can be used to enable the
1157 processing of muted channels.
1158 - support for sostenuto pedal
1159 - support for monitoring the total number of active voices
1160 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1161 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1162 - fixed some memory management errors
1163 - fixed some concurrency problems that could lead to crashes when
1164 LSCP commands were executed
1165 - fixed crash when instrument loading failed previously on the same
1166 sampler channel (fixes bug #36)
1167
1168 Version 0.3.3 (15 July 2005)
1169
1170 * packaging changes:
1171 - fixed compilation with gcc 4.0
1172
1173 * Gigasampler format engine:
1174 - LFO preprocessing was performed even though the respective LFO was
1175 disabled by the instrument patch (minor efficiency fix)
1176 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1177 for volume ramp downs in the same fragment (needed for current voice
1178 stealing implementation) then simply inform the user with a warning
1179 about possible click sounds and reduce the volume ramp down
1180 appropriately instead of cancelling the audio device connection
1181
1182 Version 0.3.2 (24 June 2005)
1183
1184 * packaging changes:
1185 - updated autotools build files to compile on OS X
1186 (conditional compilation of CoreMIDI and MidiShare drivers)
1187 - hand-crafted assembly optimization code can be disabled with
1188 './configure --disable-asm' (definitely not recommended)
1189 - fixed 'make dist' rule to include all necessary files
1190 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1191 (due to 'dist-bzip2' automake option)
1192
1193 * Gigasampler format engine:
1194 - support for the gig parameters for "release velocity response" curves
1195 - fine tuning of the EGADSR envelope
1196 - volume of release triggered samples now depends on note-on velocity,
1197 note length and gig parameter "release trigger decay" instead of
1198 note-off velocity.
1199 - revised voice stealing
1200 (fixes crash and endless loop caused by voice stealing)
1201 - don't reset scale tuning on instrument or audio output device change
1202 - handle key group conflicts right at the beginning of each fragment
1203 instead of when the respective voice is actually launched
1204 (fixes undefined behavior if stolen voices belonged to a key group -
1205 this case was followed by a "killed voice survived" error message)
1206 - fixed minor issue with null/silence samples
1207 (those stole voices even though they don't need a voice at all which
1208 resulted in "voice stealing didn't work out" messages)
1209 - don't reset volume, pan, pitch and MIDI controller values on
1210 instrument or audio output device change
1211
1212 * LSCP server:
1213 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1214 - fixed LSCP event "CHANNEL_INFO" notification
1215 (e.g. did not notify on volume changes or MIDI program change events)
1216
1217 * linuxsampler application:
1218 - added command line parameters --lscp-addr and --lscp-port to override
1219 default IP address and port of LSCP server
1220
1221 Version 0.3.1 (24 May 2005)
1222
1223 * initial release
