* All engines: Implemented scheduler for delayed MIDI events and for
  suspended real-time instrument scripts.
* Real-Time instrument scripts: Implemented support for built-in "wait()"
  function's "duration-us" argument, thus scripts using this function are
  now correctly resumed after the requested amount of microseconds.
* Real-Time instrument scripts: Implemented support for built-in
  "play_note()" function's "duration-us" argument, thus notes triggered
  with this argument are now correctly released after the requested amount
  of microseconds.
* Real-Time instrument scripts: Fixed crash which happened when trying to
  reference an undeclared script variable.
* Real-Time instrument scripts: Script events were not cleared when
  engine channel was reset, potentially causing undefined behavior.
* All engines: Attempt to partly fix resetting engine channels vs.
  resetting engine, an overall cleanup of the Reset*(),
  ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be
  desirable though, because the current situation is still inconsistent
  and error prone.
* Bumped version (2.0.0.svn2).

1 Version SVN trunk (?)
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
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.
20 * packaging changes:
21 - removed unnecessary dependency to libuuid
22 (originated by libgig's usage of it)
24 * Real-time instrument scripts:
25 - Implemented scheduler for delayed MIDI events and for suspended scripts.
26 - Built-in script function "wait()": implemented support for function's
27 "duration-us" argument, thus scripts using this function are now
28 correctly resumed after the requested amount of microseconds.
29 - Built-in script function "play_note()": implemented support for
30 function's "duration-us" argument, thus notes triggered with this
31 argument are now correctly released after the requested amount of
32 microseconds.
33 - Fix: script events were not cleared when engine channel was reset,
34 potentially causing undefined behavior.
35 - Fixed crash which happened when trying to reference an undeclared
36 variable.
38 Version 2.0.0 (15 July 2015)
40 * packaging changes:
41 - fixed building with newer MinGW-w64
42 - Mac OS X: support the new dir for Core Audio SDK
43 - Mac OS X: fixed building outside source directory
44 - made sure all source files for hostplugins are included when

55 - fixed compilation with gcc 4.7
56 - fixed configure script error with old autoconf versions
57 - lsatomic.h: use gcc provided atomic functions if building with
58 gcc 4.7 and C++11
59 - modernized configure script
60 - fixed linkage error when building with
61 LDFLAGS="-Wl,--no-undefined" (#190)
62 - fixed compilation with Clang 3.2
63 - removed usage of deprecated Automake variable INCLUDES
64 - fixed building with C++11
65 - build fix: ChangeFlagRelaxed.h was missing in makefile
66 - build fix: libsndfile compiler flags were missing in some
67 makefiles
68 - fix for building with bison 3.0 (#202)
69 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
70 on the process's main thread
71 - fixed build error on newer MinGW
72 - support building with older jack versions
73 - support building with spaces in vst sdk path
74 - enabled automake 'subdir-objects' option and moved external
75 source references (vst, au, asio) from makefiles to cpp files,
76 in order to get rid of warnings from automake 1.14
78 * general changes:
79 - Refactoring: moved the independent code from
80 the Gigasampler format engine to base classes
81 - command line option '--profile' is currently disabled, since the
82 respective profiling code is currently broken
83 - Introduced support for optional environment variable
84 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
85 where the sampler shall look for instrument editor plugins
86 (patch by Luis Garrido, slightly modified).
87 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
88 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
89 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
90 note (in this implementation of the sampler its simply hard routed to
91 the 1st effect send of the sampler channel, no matter what the actual
92 effect type is)
93 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
94 note (in this implementation of the sampler its simply hard routed to
95 the 2nd effect send of the sampler channel, no matter what the actual
96 effect type is)
97 - implemented support for internal LADSPA effects
98 - raised limit of program change queue from 100 to 512
99 (as suggested by Alex Stone)
100 - implemented sine LFO, pulse LFO and saw LFO
101 - experimental support for per voice equalization
102 - added command line option --exec-after-init
103 - Introduced new C++ API method:
104 EngineChannel::InstrumentFileName(int index)
105 allowing to retrieve the whole list of files used for the loaded
106 instrument on an engine channel (a.k.a. part). Some GigaStudio
107 instruments for example are splitted over several files like
108 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
109 - Added new C++ API method Sampler::GetGlobalMaxVoices().
110 - Added new C++ API method Sampler::GetGlobalMaxStreams().
111 - Added new C++ API method Sampler::SetGlobalMaxVoices().
112 - Added new C++ API method Sampler::SetGlobalMaxStreams().
113 - Various "const" and "restrict" optimizations.
114 - all engines: add pan CC value to instrument pan parameter before
115 applying panning, instead of using two separate pan functions in
116 series (#182)
117 - added a lock guard class for exception safe mutex handling and
118 used it everywhere appropriate
119 - Immediately apply scale tuning changes to active voices.
120 - Exposed scale tuning to C++ API (along to the already existing standard
121 SysEx way).
122 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
123 and broken for ppc64. (Seq_cst loads and stores are actually not
124 used in LS, so the bug wasn't noticable.)
125 - lsatomic.h: added ARMv7 support
126 - Added support for multiple MIDI input ports per sampler channel (and
127 added various new C++ methods for this new feature / design change, old
128 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
129 as deprecated but are still there and should provide full behavior
130 backward compatibility).
131 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
132 unsafe and caused compilation error with clang 2.x).
133 - Bugfix: only process the latest MIDI program change event.
134 - Introducing the LSCP shell, which provides convenient control of the
135 sampler from the command line by providing LSCP aware features.
136 - VirtualMidiDevice: Added support for program change.
137 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
138 - VirtualMidiDevice: Added support for pitch bend.
139 - Aftertouch: extended API to explicitly handle channel pressure and
140 polyphonic key pressure events (so far polyphonic pressure was not
141 supported at all, and channel pressure was rerouted as CC128 but not
142 used so far).
143 - Added initial support for real-time instrument scripts. The script VM
144 code is shared by all sampler engine implemementations, however only the
145 gig file format currently provides support for storing instrument scripts
146 (as LinuxSampler extension to the original GigaStudio 4 format).
148 * Gigasampler format engine:

150 - fixed round robin and random dimensions for cases when number of
151 dimension zones is not a power of two

153 key
154 - bugfix: pitch LFO controller "internal+aftertouch" was broken
155 - bugfix: filter keyboard tracking was broken
156 - filter performance fix (an unnecessary copy was made of the
157 filter parameters in each sub fragment)
158 - handle special case when pan parameter in gig file has max or
159 min value
160 - Exclusive Groups: don't ever stop voices of the same note,
161 doesn't sound naturally with a drumkit
162 - fixed EG1 modulation when attack or release is zero
163 - Fixed support for 'aftertouch' attenuation controller.
164 - Fixed crash that happened with velocity split sounds under certain
165 conditions (see also previous commit on libgig).
166 - fixed behaviour of filter LFO
168 * SFZ format engine:
169 - Initial implementation (not usable yet)
170 - added support for v2 multiple stage envelope generators

174 - added support for trigger=first, trigger=legato and sw_previous
175 - allow non-numerical key values ("C#4" for example)

177 - fixed error when unloading instrument with same sample used by
178 multiple regions
179 - added some opcode aliases, like loopmode for loop_mode, to be
180 more compatible
181 - added support for trigger=release and rt_decay
182 - added support for off_mode=normal

190 - added more v1 aliases to parser
191 - reduced memory usage for sfz data
192 - RT-safeness: avoid malloc in audio thread
193 - fixed a bug that could cause voice stealing to fail
194 - optimized sample lookup
195 - improved support for exclusive groups (group, off_by and
196 off_mode)
197 - added support for controller triggered regions (on_locc/on_hicc)
198 - added support for loop_mode=one_shot
199 - fixed playback of 16 bit wav files on big endian CPUs
200 - added support for Ogg Vorbis sample files
201 - use loop markers from sample file if loop_start and loop_end are
202 not set in sfz file

331 - added support for float and 32 bit sample files
333 * SoundFont format engine:
334 - Initial implementation (not usable yet)
335 - RT-safeness: avoid malloc in audio thread

343 - AU bugfix: failed to destroy its audio/MIDI devices
344 - Listen to all interfaces on Mac OS X (INADDR_ANY)
345 - VST bugfix: If the host called resume() before and after
346 changing sample rate or block size, the number of channels was
347 incorrectly set to two. This caused silence in Cubase 5.
348 - save engine type (gig, sfz or sf2) in plugin state
349 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
350 64 bit Windows

357 - VST bugfix: instrument loading hang and crashed the host when
358 the plugin was loaded a second time (#174)
359 - plugin bugfix: instrument loading hang when the plugin was
360 loaded a second time (this time it's for Linux and Mac, previous
361 similar fix was for Windows)
362 - thread safety fixes for the instrument loading thread
363 - LV2: use the new lv2 package if present
364 - VST: try to open Fantasia automatically on Linux and Mac too (on
365 Linux, the Fantasia jar should be placed in <prefix>/share/java)
366 - VST: fixed crashes on Linux Ardour and EnergyXT
367 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
368 port and audio channel routing for DSSI plugins are now visible.
369 - LV2: use urid and atom extensions instead of deprecated uri-map
370 and event
371 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

375 - LV2: made LV2 plugin buildable on Windows and Mac
376 - VST: implemented retrieval and switching of programs using the
377 sampler's internal MIDI instrument mapping system
379 * Instrument editor interface:
380 - Changed instrument editor plugin interface, providing additional
381 informations like the EngineChannel for which the instrument editor was
382 spawned for. This allows the instrument editors to interact more actively
383 with the sampler.
385 * MIDI driver:
386 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
387 the ALSA sequencer client name
388 - removed limit of maximum amount of MIDI ports per MIDI device, since
389 there is no reason for this limit
390 - MME: fixed memory handling bug found with cppcheck
391 - MME: removed compiler warning
392 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
393 which allows to retrieve the list of CoreMIDI clients / ports and to connect
394 to them a la JACK, via the usual sampler APIs
395 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
396 the driver will automatically connect to other CoreMIDI clients' ports
397 (e.g. external MIDI devices being attached to the Mac)
398 - added support for MIDI note on velocity filter
399 - CoreMIDI: fixed memory deallocation error
400 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
401 virtual keyboards in frontends / instrument editors being stuck.
402 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
403 - Implemented missing handling of MIDI "running status".
404 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
405 - MME bugfix: driver wasn't closed properly
406 - CoreMIDI: automatically connect to all input sources by default (driver
407 parameter "AUTO_BIND").
408 - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online

529 channel to a different engine type
530 - fixed crash when deleting a sampler channel or changing engine
531 type while an instrument load was in progress
532 - bugfix: playing a note while changing the instrument could cause
533 a crash, or give "Handing back unknown region" error messages
534 - bugfix: calling SET VOICES (which Fantasia does on start and
535 refresh) could cause instruments to be unloaded
536 - Mac OS X: fixed name collision of enum in EffectControl and
537 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
538 - Mac OS X: fixed hanging threads
539 - Windows: disabled the previous thread fix on non-Mac systems, as
540 it caused hanging threads on Windows
541 - Fixed possible crashes due to corrupted MIDI/audio device list
542 after MIDI/audio device creation failure
543 - When creating MIDI instrument map entries with "PERSISTENT" type, the
544 instruments were uselessly precached with zero samples, however it still
545 took the full preloading time and on 1st program change the respective
546 instrument was completely reloaded again.
547 - fixed handling of rapid bank select and program change messages
548 sent to the same sampler channel (patch from the Open Octave
549 project, slightly adjusted)
550 - fixed crash when trying to create an effect instance with controls
551 which min and/or max values depend on the sample rate

568 crashes and noise on such transitions).
569 - ignore missing LADSPA paths without ignoring valid LADSPA paths
570 (fixes #208)
571 - Fixed bug in LSCP grammar definition which caused a statement like
572 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
573 practically irrelevant, however it caused problems with the new LSCP
574 shell's auto completion feature).
575 - Fixed MIDI program change messages being ignored if quickly executed
576 after each other (fixes #231).
578 Version 1.0.0 (31 July 2009)
580 * packaging changes:
581 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

591 - minor fix in configure for mmsystem.h detection on MinGW
592 - Windows: look for editor plugins and Fantasia using base
593 directory of liblinuxsampler dll (look in the same directory and one
594 directory above)
595 - configure script fix: removed unconditional use of SSE
596 - fixed building with sqlite installed in a non-standard directory
597 - when cross-compiling, don't try to create instruments.db
598 - fix for new mingw-w64 version, which has usleep
600 * general changes:
601 - bugfix: on some POSIX systems instrument editor plugins refused to
602 load as we used a non-portable Linux specific struct field
603 (fixes bug #70, patch by Ronald Baljeu)
604 - fixed endless loop which occured when loading an instrument editor
605 plugin DLL on Windows systems failed
606 - fixed memory leaks that occurred when liblinuxsampler was unloaded
607 - optimized the SynchronizedConfig class so it doesn't wait
608 unnecessarily long after an update
609 - added support for notifying instrument editors on note-on / note-off
610 events (e.g. to highlight the pressed keys on the virtual keyboard
611 of gigedit)
612 - added support for triggering notes by instrument editors (see above)
613 - be verbose on DLL load errors (on Linux)
614 - fixed di-harmonic triangle LFO implementation (this LFO implementation
615 is only used by very few systems, most pick the int math
616 implementation, which is usually faster)
617 - fixes for audio drivers with varying buffer sizes
618 - experimental support for running LinuxSampler as a DSSI, LV2 and
619 VST plugin
620 - notification events for stream/voice count statistics are now sent
621 only when there are actual changes
622 - added memory ordering constraints to improve stability on
623 multi-core and multi-cpu systems
624 - maximum voices and disk streams can now be altered at runtime
625 - fixed CPU feature detection on x86_64 (maybe fixes #108)
626 - automatic stacktrace mechanism is now turned off by default and can
627 be switched on by command line option "--stacktrace" (the automatic
628 stacktrace mechanism seems to be broken on most systems at the moment)
629 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
630 a pointer to the launched InstrumentEditor object
631 - added optional 3rd party user data parameter for following
632 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
633 InstrumentEditor::Launch(),
634 InstrumentManager::LaunchInstrumentEditor()
635 - theoretical fix: made SynchronizedConfig follow C++0x memory
636 model more strictly
637 - fixes for using large audio device buffers
638 - Windows: add the installation directory to the DLL search path
639 when loading an editor plugin (solves problems with VST and
640 gigedit on systems with other GTK versions installed)
641 - updated linuxsampler man page
643 * audio driver:
644 - removed the nonsense audio channel constraint (which was hard coded to
645 max. 100 audio channels) for most audio drivers
646 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
647 opposed to the LSCP specs
648 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
649 reflected the wrong value
650 - fixed a memory management bug in ASIO driver
651 - Makefile fix: JACK_CFLAGS wasn't used
652 - JACK: use jack_client_open instead of the deprecated
653 jack_client_new
654 - added (experimental) CoreAudio driver
655 - applied old fixes to the ASIO driver that were included in the
656 previous binary release but accidentally never committed to CVS
657 (fixes #117)
658 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
659 win64)
660 - VST: added support for sample rate and buffer size changes
661 - VST: close editor (Fantasia) when the VST is removed
662 - VST: avoid opening Fantasia more than once for each VST instance
663 - VST: export main function as "main" on Linux too (fix for
664 energyXT)
665 - VST: changed number of output channels from one stereo to 16
666 stereo
667 - added channel routing, fxsends and midi maps to the settings
668 stored in the plugin state
669 - performance optimization of AudioChannel::MixTo() and
670 AudioChannel::CopyTo() methods using GCC vector exensions
671 (if available)
672 - ASIO fixes: avoid initializing the device twice, avoid throwing
673 exception when getting parameters from a disconnected device
675 * MIDI driver:
676 - added JACK MIDI driver
677 - dispatch bank select as ordinary CC as well, the user might seriously
678 want to (mis)use it for some purpose ("fixed" in all current MIDI
679 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
680 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
681 CoreMidi or AU
682 - fixed mingw-w64 compilation error in MME driver
683 - made program change handling in MIDI thread real-time safe by
684 moving the logic to a non-RT thread
685 - fixed minor memory leak in ALSA driver
687 * instruments database:
688 - avoid time consuming samples scanning when adding instruments
689 to the instruments database
690 - added support for handling lost files in the instruments database
691 - Implemented option for adding instruments in separate directories
692 in the instruments database
693 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
694 - work-around for missing fnmatch function on Windows to make
695 instrument database compilable
696 - added instrument database support on Windows
697 works with both standalone mode and VST plugin.
698 the instruments DB file is located in
699 %USERPROFILE%\.linuxsampler\instruments.db which allows different
700 databases for each windows user
701 if no DB is present it automatically creates the .linuxsampler subdir
702 and then creates an empty DB
703 - fixed recursive import, which was broken on Windows
705 * Gigasampler format engine:
706 - fixed a memory leak that could happen when a channel was deleted
707 while notes were playing
708 - made it possible to load an instrument even if the audio thread
709 isn't running
710 - added partial support for the "Controller Triggered" MIDI rule,
711 enough for piano gigs with pedal noise samples
712 - minor fix: only mark FX sends as being modified if really the
713 respective FX send MIDI controller was used
714 - added support for GM global device volume SysEx message
715 (can be selected at compile time to either apply globally to the
716 whole sampler [default] or only to the sampler channels that are
717 connected to the respective MIDI input port the SysEx message arrived
718 on)
719 - bugfix: notes triggered at position 0 in the audio buffer were
720 sometimes wrongly killed in the same buffer, causing no sound to
721 be played
722 - added support for chromatic / drumkit mode Roland GS Sysex message
723 which is usally used to switch a part between chromatic sounds and
724 drumkit sounds (as opposed to their common default setting of MIDI
725 part 10 being a drumkit part and all other ones chromatic parts), in
726 LS however one can switch between the first 16 MIDI instrument maps
727 defined for the sampler
728 - made it possible to create multiple sample channels even if the
729 audio thread isn't running
730 - fixed crash when removing channel with active voices (#116)
731 - bugfix: on sample reference changes (instrument editor), only
732 un-cache the respective sample if it's really not used by any
733 sampler engine anymore
734 - re-cache samples in case they were changed by an instrument editor,
735 e.g. when a sample was added while playing (#82)
736 - fixed hanging notes which occured when note-off event had the exact
737 same time stamp as the voice's note-on event and occured both in the
738 same audio fragment cycle (fixes bug #112)
739 - added support for the "fine tune" and "pitch bend range"
740 instrument-level gig parameters
741 - fixed minor artifacts in pitch bend handling
742 - added support for GS Reset SysEx message
743 - allow gig files to use unlimited downward pitch shifting
744 - added a limit check for upward pitch shifting
745 - bugfix: sometimes, when playing a note twice fast, the second
746 note was silent
747 - fixed crash happening when a pitch bend event arrived at the
748 same time a new instrument was loading
750 * LSCP server:
751 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
752 react on MIDI data arriving on certain sampler channels (so far only
753 Note-On and Note-Off events are sent via this LSCP event)
754 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
755 react on MIDI data arriving on certain MIDI input devices (so far only
756 Note-On and Note-Off events are sent via this LSCP event)
757 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
759 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
760 frontends to send MIDI messages to specific sampler channel
761 - added two additional fields to GET FILE INSTRUMENT INFO command -
763 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
764 was incorrect
765 - Optimized the retrieval of the MIDI instrument mappings
766 - added new LSCP command "SET VOICES" to globally alter the maximum
767 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
768 be triggered respectively
769 - added new LSCP command "SET STREAMS" to globally alter the maximum
770 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
771 which will be triggered respectively
772 - bugfix: retry if "select" returns EINTR (this fixes a crash when
773 a gigedit file dialog is opened)
774 - close all connections when LSCPServer is deleted
775 - hard close of all sockets on exit
776 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
777 driver
779 * Bug fixes:
780 - fixed a crash which occurs when removing a sampler channel waiting
781 to start instrument loading after another channel
782 - fixed a crash which occurs when removing a sampler channel with
783 instrument loading in progress (bug #113)
784 - fixed termination caused by uncaught exception when adding MIDI
785 instrument with PERSISTENT load mode
786 - fixed possible iterator invalidations when resetting the sampler
787 - fixed memory leaks when issuing the following LSCP commands:
792 - fixed possible compilation error when sqlite is not present
793 - fixed orphaned pointers when setting maximum voices limit (bug #118)
794 - fixed crash when changing the audio output device of a sampler
795 channel with loaded instrument and start playing notes
796 - fixed endless loop in Engine::SuspendAll() (bug #120)
797 - fixed a low-level atomic load function that was broken on 64-bit
798 PowerPC, which probably could cause crashes on that platform
799 - fixed a memory management error which could cause a crash when a
800 plugin was unloaded
801 - bugfix: two private structs had the same name, which could cause
802 problems if the linker chose the wrong constructor
803 - fixed low-level ConditionServer usage bug that caused lockups on
804 Windows
807 Version 0.5.1 (6 December 2007)
809 * packaging changes:
810 - added autoconf checks for pthread library
811 - added autoconf check for pthread bug found on certain NPTL-enabled
812 glibc versions (see Gentoo bug report #194076)
813 - added autoconf checks for MS Windows
815 * general changes:
816 - bugfix: the thread used by an editor plugin didn't die when the
817 editor closed
818 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
819 out all the space. operator--() did not apply size_mask after
820 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
821 order to avoid problems with the _NonVolatileReader functions.
822 - bugfix: Stream.h: added a missing divide by BytesPerSample in
823 GetWriteSpace(). Since this function is currently only used in
824 the stream's qsort() compare function, it didn't trigger any
825 bugs.
826 - Resampler.h, Synthesizer.h: cubic interpolation now works in
827 24bit mode too. Faster method to read 24bit words on little
828 endian machines (x86): replaced 3 byte reads + shifts with a 1
829 unaligned 32bit read and shift
830 - experimental support for MS Windows (MIDI input via MME, AUDIO
831 output via ASIO)
832 - made handling of SIGINT signal (Ctrl-C) a bit more robust
833 - support for monitoring the total number of active disk streams
834 (new LSCP commands: GET TOTAL_STREAM_COUNT,
837 * AUDIO driver:
838 - added Windows ASIO low latency audio driver
840 * MIDI driver:
841 - added MME Windows MIDI driver
843 * LSCP server:
844 - added support for Windows style path / filenames, however with
845 forward slash path separators instead of backslash
846 (i.e. "C:/foo/bar.gig")
847 - allow naughty liblscp to send non-string device parameters within
848 apostrophes as well
849 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
850 "LIST FILE INSTRUMENTS <file>" and
851 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
852 about an arbitrary instrument file on the system where the sampler is
853 running on
855 Version 0.5.0 (15 October 2007)
857 * packaging changes:
858 - config.h is not going to be installed along with liblinuxsampler's
859 API header files anymore
860 - only the API relevant header (and source) files will be exported to
861 the Doxygen API documentation (explicitly listed in Doxyfile.in)
862 - added completely new XCode project files for Mac OSX which is now
863 capable to execute our autoconf environment, thus no need anymore
864 to maintain the compile time configuration file (osx/version.h) for
865 OSX manually (patch by Toshi Nagata)
866 - fixed buggy boolean --enable-foo / --disable-foo configure script
867 parameters
868 - global.h now only covers global definitions that are needed for the
869 C++ API header files, all implementation internal global definitions
870 are now in global_private.h
871 - atomic.h is not exposed to the C++ API anymore
872 - no need to include config.h anymore for using LS's API header files
873 - fixed warnings in API doc generation
875 * general changes:
876 - replaced the old, confusing MIDI program change mechanism by a
877 flexible MIDI instrument mapper which allows to map arbitrary
878 (MIDI bank, MIDI program) pairs with arbitrary
879 (engine type, instrument file, file index) triplets which will be
880 loaded on the respective channel when such MIDI program change
881 messages arrive, beside that, each entry allows to define a life-time
882 strategy for the instrument, so the user can define whether the
883 instrument should i.e. be permanently loaded (to be able to switch
884 quickly among sounds) or i.e. loaded just on demand when the
885 respective program change arrives (to safe RAM space), as well as a
886 global volume factor for each entry, so the user can adjust the volume
887 dynamic of his mapped instrument collection without having to modify
888 the instrument files, also one can manage arbitrary amount of such
889 MIDI instrument maps and assign each sampler channel individually
890 a certain map, so that i.e. separation of normal instruments and
891 drumkits is possible
892 - new notification events for tracking changes to audio/MIDI devices,
893 MIDI instrument maps, MIDI instruments, FX sends, global volume.
894 - sampler was limited to load max. 200 instruments in the background
895 due to a constant size RingBuffer FIFO which is now replaced by a
896 dynamic (unlimited) size std::list FIFO
897 - added FX sends, these allow to route audio signals to arbitrary audio
898 output channels for being processed by external effect processors
899 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
900 controllers
901 - global (sampler wide) volume can now be controlled at runtime
902 - Implemented new, improved notification system
903 - fixed compilation errors regarding OSX
904 (patch by Toshi Nagata)
905 - implemented instruments database
906 - added support for escape sequences to the instruments database
907 - added highly experimental support for on-the-fly instrument editing
908 within the sampler's process (by using instrument editor plugins),
909 you'll notice the new "Registered instrument editors:" message on
910 startup, added a new LSCP command:
911 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
912 to spawn a matching instrument editor for the instrument on the
913 given sampler channel, the plugin path can be overridden at compile
914 time with ./configure --enable-plugin-dir=/some/dir
915 - added experimental code for synchronizing instrument editors hosted
916 in the sampler's process to safely edit instruments while playing
917 without a crash (hopefully) by either suspending single regions
918 wherever possible or if unavoidable whole engine(s)
919 - fixed several issues in fundamental "Thread" class: set scheduling
920 policy and priority on thread level, set a minimum stack size for
921 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
922 threads simply inherited properties of starting thread instead of
923 setting their own policy and priority
924 - minor fix in our automatic stack trace mechanism on crashes, the
925 main process did not wait for the stack trace process to finish
926 its output
927 - fixed some minor memory leaks
928 - reenabled assembly features support, at the moment only for
929 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
930 - minor assembly fix in x86 features detection (don't use the PIC
931 register, to avoid relocations in the text segment at runtime)
932 - POSIX callback functions of Thread.h are hidden
934 * MIDI driver:
935 - dispatch bank select (MSB and LSB) messages
937 * audio driver:
938 - the ALSA audio output driver parameters now reflect the correct
939 parameter value ranges for the respective selected sound card
940 (patch by Till Wimmer, a bit fixed and extended)
942 * Gigasampler format engine:
943 - if a filter is used and EG2 finishes before EG1, let the voice
944 die when EG2 has finished (this fixes a problem with clicks and
945 voice starvation for some gigs)
946 - playback is no longer disabled during instrument loading
947 - all notes playing on a channel that changes its instrument keep
948 playing with the old instrument until they get a note off
949 command
950 - EG fix: a release value of zero could cause noises or crash
951 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
952 - EG fine tuning: when attack is zero the EG starts at a level
953 above max sustain level, which means that there is a decay phase
954 even if sustain is 100%
955 - more EG fixes: the level could sometimes go below zero and cause
956 noises or crashes
957 - minor fix of EGDecay (patch by Toshi Nagata)
958 - fixed compiler error when --enable-override-filter-type was
959 supplied to the configure script (fixes #46)
960 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
961 instead of a fix value
962 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
963 127 (solo mode) only kill voices if the respective mode really
964 changed
966 * LSCP server:
967 - fixed compile time error for old Bison versions
968 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
969 - parser now supports extended ASCII character set
970 (up to ASCII code 255, i.e. includes now umlauts and accents)
971 - filename arguments in LSCP commands now allow to use escape
972 sequences, that is directly literal as one of: \', \", \\, \n, \r,
973 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
974 code value like \xf2) (fixes bug #24)
975 - the following LSCP commands now also support escape sequences for at
976 least one of their text-based parameters (i.e. name, description):
983 - returns verbose syntax errors (line and column where syntax error
984 occured, the unexpected character and the actually expected, possible
985 character(s), the latter only if less than 5 possibilities)
986 - made sure that LSCP syntax is not affected by gigedit locale
987 settings
988 - bugfix regarding strings parameter lists: all comma separated lists
989 of strings were treated as being one string containing commas
990 (fixes #57)
992 * Bug fixes:
993 - fixed crash occurring on certain LSCP scripts (Bug 39)
994 - another thread safety fix for lscp "load engine" and "set
995 channel audio output device"
996 - fixed a crash which occurs when reassigning the same engine
997 on a sampler channel with connected MIDI device
998 - fixed a crash which occurs when changing the number of ports of a MIDI
999 device connected to a sampler channel to number less then or equal
1000 to the index of the port to which the sampler channel is connected.
1001 - The previous bindings were not been disconnected when altering
1002 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1003 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1004 - The active stream/voice count statistic was incorrect.
1005 - notification events were not been sent for some sampler
1006 channel changes
1007 - added default min and max values to restrict the number of allowed
1008 audio output channels and MIDI input ports
1009 - the connection to the PCM interface is now closed when destroying
1010 an audio output device
1011 - files with slash in their path or filename could not be loaded
1013 * test cases:
1014 - updated and fixed (haven't been touched in a while)
1016 Version 0.4.0 (24 November 2006)
1018 * packaging changes:
1019 - changed deprecated copyright attribute to license; added ldconfig
1020 to post-(un)install steps; added devel package for liblinuxsampler;
1021 to linuxsampler.spec (RPM)
1022 - install necessary development header files for allowing 3rd party
1023 applications to link against liblinuxsampler
1024 - liblinuxsampler's API documentation can be generated with 'make docs'
1025 (Doxygen required)
1026 - added benchmark to automatically detect the best triangle LFO
1027 implementation (currently either an integer math solution or a
1028 di-harmonic approximation), automatic detection can be overriden
1029 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1030 configure script argument though (mandatory for cross-compilation)
1031 - do not automatically pick optimized gcc flags if the user already
1032 provided some on his own (as CXXFLAGS)
1033 - added compile time option to disable processing of All-Notes-Off MIDI
1034 messages
1035 - added compile time options to allow disabling the various audio and
1036 MIDI drivers
1037 - fixed automatic GCC CPU switch detection on PPC
1038 (patch by Ebrahim Mayat)
1040 * Gigasampler format engine:
1041 - extensive synthesis optimization
1042 (reimplementation of EGs and LFO(s), removed synthesis parameter
1043 prerendering and the synthesis parameter matrix in general, splitting
1044 each audio fragment into subfragments now where each subfragment uses
1045 constant pitch and filter coefficients. The volume coefficient is
1046 linearly interpolated inside a subfragment, unless
1047 --disable-interpolate-volume is set.)
1048 - fine tuning of the EG modulation parameters
1049 - improved filter cutoff calculation by adding support for the
1050 following gig parameters: Cutoff freq (used when no cutoff
1051 controller is defined), Control invert, Minimum cutoff, Velocity
1052 curve and Velocity range. The keyboard tracking now scales
1053 cutoff frequency instead of resonance.
1054 - added support for gig parameter Resonance.
1055 - fixed bug in sysex handling (patch by Juan Linietsky)
1056 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1057 which can be overridden with --enable-global-attenuation
1058 - EG fixes: made the length of "attack hold" stage more
1059 accurate. Release stage can now start before attack stage
1060 ends. Cancel release didn't work when sustain was zero. Attack
1061 time now has a minimal value to prevent clicks.
1062 - fixed pitch changes larger than one octave
1063 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1064 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1065 all modes can be altered via standard GM messages, that is CC5 for
1066 altering portamento time, CC65 for enabling / disabling portamento
1067 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1068 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1069 parameter) and crossfade
1070 - added support for the "attenuation controller threshold" gig
1071 parameter
1072 - added smoothing of volume changes caused by control change
1073 messages
1074 - sample loop parameters are now taken from the DimensionRegion
1075 instead of the wave chunk
1076 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1077 not equal to a power of two
1078 - reimplementation of the filter algorithm. The new filter is more
1079 accurate and supports all gig filter types, including bandreject
1080 and lowpass turbo.
1081 - real support for 24 bit samples - samples are not truncated to
1082 16 bits anymore
1083 - support for aftertouch (channel pressure, not polyphonic
1084 aftertouch)
1085 - LFO1 behaviour fixed (dampening from max volume instead of
1086 amplifying from 0)
1088 * LSCP server:
1089 - fixed application exit on broken pipe error (fixes bug #20)
1090 - fixed the notification messages delay due to lack of
1091 network activity (fixes bug #26)
1092 - fixed parser bug which occured on space(s) within device parameters
1095 * audio driver:
1096 - added aRts audio output driver (by no means RT safe)
1098 * MIDI driver:
1099 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1100 messages several times instead of once
1101 - API extension for MIDI drivers which already supply exact time stamps
1102 for events (i.e. for offline rendering based MIDI drivers)
1103 - added checks for bad MIDI data
1105 * linuxsampler application:
1106 - show available sampler engine types on startup
1108 * general changes:
1109 - support for muting sampler channels and solo mode of the same, two new
1110 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1111 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1112 introduced for this, the behavior is the same like on a mixer console
1113 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1114 --enable-process-muted-channels which can be used to enable the
1115 processing of muted channels.
1116 - support for sostenuto pedal
1117 - support for monitoring the total number of active voices
1120 - fixed some memory management errors
1121 - fixed some concurrency problems that could lead to crashes when
1122 LSCP commands were executed
1123 - fixed crash when instrument loading failed previously on the same
1124 sampler channel (fixes bug #36)
1126 Version 0.3.3 (15 July 2005)
1128 * packaging changes:
1129 - fixed compilation with gcc 4.0
1131 * Gigasampler format engine:
1132 - LFO preprocessing was performed even though the respective LFO was
1133 disabled by the instrument patch (minor efficiency fix)
1134 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1135 for volume ramp downs in the same fragment (needed for current voice
1136 stealing implementation) then simply inform the user with a warning
1137 about possible click sounds and reduce the volume ramp down
1138 appropriately instead of cancelling the audio device connection
1140 Version 0.3.2 (24 June 2005)
1142 * packaging changes:
1143 - updated autotools build files to compile on OS X
1144 (conditional compilation of CoreMIDI and MidiShare drivers)
1145 - hand-crafted assembly optimization code can be disabled with
1146 './configure --disable-asm' (definitely not recommended)
1147 - fixed 'make dist' rule to include all necessary files
1148 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1149 (due to 'dist-bzip2' automake option)
1151 * Gigasampler format engine:
1152 - support for the gig parameters for "release velocity response" curves
1153 - fine tuning of the EGADSR envelope
1154 - volume of release triggered samples now depends on note-on velocity,
1155 note length and gig parameter "release trigger decay" instead of
1156 note-off velocity.
1157 - revised voice stealing
1158 (fixes crash and endless loop caused by voice stealing)
1159 - don't reset scale tuning on instrument or audio output device change
1160 - handle key group conflicts right at the beginning of each fragment
1161 instead of when the respective voice is actually launched
1162 (fixes undefined behavior if stolen voices belonged to a key group -
1163 this case was followed by a "killed voice survived" error message)
1164 - fixed minor issue with null/silence samples
1165 (those stole voices even though they don't need a voice at all which
1166 resulted in "voice stealing didn't work out" messages)
1167 - don't reset volume, pan, pitch and MIDI controller values on
1168 instrument or audio output device change
1170 * LSCP server:
1171 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1172 - fixed LSCP event "CHANNEL_INFO" notification
1173 (e.g. did not notify on volume changes or MIDI program change events)
1175 * linuxsampler application:
1176 - added command line parameters --lscp-addr and --lscp-port to override
1177 default IP address and port of LSCP server
1179 Version 0.3.1 (24 May 2005)
1181 * initial release
