* NKSP: Implemented built-in script function "change_attack()".
* NKSP: Implemented built-in script function "change_decay()".
* NKSP: Implemented built-in script function "change_release()".
* Bumped version (2.0.0.svn19).

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 - NKSP language correction: allow empty statements in entire language
89 (i.e. "if end if").
90 - Implemented built-in script function "stop_wait()".
91 - Implemented built-in script variable "$NI_CALLBACK_ID".
92 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94 - Added support for read-only built-in variables (respectively
95 handled by the script parser).
96 - Added built-in script constant "$NI_CB_TYPE_INIT".
97 - Added built-in script constant "$NI_CB_TYPE_NOTE".
98 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
100 - NKSP Language: Added support for user defined script functions.
101 - Implemented built-in script function "change_attack()".
102 - Implemented built-in script function "change_decay()".
103 - Implemented built-in script function "change_release()".
104

140 - support building with spaces in vst sdk path
141 - enabled automake 'subdir-objects' option and moved external
142 source references (vst, au, asio) from makefiles to cpp files,
143 in order to get rid of warnings from automake 1.14
144
145 * general changes:
146 - Refactoring: moved the independent code from
147 the Gigasampler format engine to base classes
148 - command line option '--profile' is currently disabled, since the
149 respective profiling code is currently broken
150 - Introduced support for optional environment variable
151 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
152 where the sampler shall look for instrument editor plugins
153 (patch by Luis Garrido, slightly modified).
154 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
155 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
156 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
157 note (in this implementation of the sampler its simply hard routed to
158 the 1st effect send of the sampler channel, no matter what the actual
159 effect type is)
160 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
161 note (in this implementation of the sampler its simply hard routed to
162 the 2nd effect send of the sampler channel, no matter what the actual
163 effect type is)
164 - implemented support for internal LADSPA effects
165 - raised limit of program change queue from 100 to 512
166 (as suggested by Alex Stone)
167 - implemented sine LFO, pulse LFO and saw LFO
168 - experimental support for per voice equalization
169 - added command line option --exec-after-init
170 - Introduced new C++ API method:
171 EngineChannel::InstrumentFileName(int index)
172 allowing to retrieve the whole list of files used for the loaded
173 instrument on an engine channel (a.k.a. part). Some GigaStudio
174 instruments for example are splitted over several files like
175 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
176 - Added new C++ API method Sampler::GetGlobalMaxVoices().
177 - Added new C++ API method Sampler::GetGlobalMaxStreams().
178 - Added new C++ API method Sampler::SetGlobalMaxVoices().
179 - Added new C++ API method Sampler::SetGlobalMaxStreams().
180 - Various "const" and "restrict" optimizations.
181 - all engines: add pan CC value to instrument pan parameter before
182 applying panning, instead of using two separate pan functions in
183 series (#182)
184 - added a lock guard class for exception safe mutex handling and
185 used it everywhere appropriate
186 - Immediately apply scale tuning changes to active voices.
187 - Exposed scale tuning to C++ API (along to the already existing standard
188 SysEx way).
189 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
190 and broken for ppc64. (Seq_cst loads and stores are actually not
191 used in LS, so the bug wasn't noticable.)
192 - lsatomic.h: added ARMv7 support
193 - Added support for multiple MIDI input ports per sampler channel (and
194 added various new C++ methods for this new feature / design change, old
195 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
196 as deprecated but are still there and should provide full behavior
197 backward compatibility).
198 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
199 unsafe and caused compilation error with clang 2.x).
200 - Bugfix: only process the latest MIDI program change event.
201 - Introducing the LSCP shell, which provides convenient control of the
202 sampler from the command line by providing LSCP aware features.
203 - VirtualMidiDevice: Added support for program change.
204 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
205 - VirtualMidiDevice: Added support for pitch bend.
206 - Aftertouch: extended API to explicitly handle channel pressure and
207 polyphonic key pressure events (so far polyphonic pressure was not
208 supported at all, and channel pressure was rerouted as CC128 but not
209 used so far).
210 - Added initial support for real-time instrument scripts. The script VM
211 code is shared by all sampler engine implemementations, however only the
212 gig file format currently provides support for storing instrument scripts
213 (as LinuxSampler extension to the original GigaStudio 4 format).
214

220 key
221 - bugfix: pitch LFO controller "internal+aftertouch" was broken
222 - bugfix: filter keyboard tracking was broken
223 - filter performance fix (an unnecessary copy was made of the
224 filter parameters in each sub fragment)
225 - handle special case when pan parameter in gig file has max or
226 min value
227 - Exclusive Groups: don't ever stop voices of the same note,
228 doesn't sound naturally with a drumkit
229 - fixed EG1 modulation when attack or release is zero
230 - Fixed support for 'aftertouch' attenuation controller.
231 - Fixed crash that happened with velocity split sounds under certain
232 conditions (see also previous commit on libgig).

265 - added support for loop_mode=one_shot
266 - fixed playback of 16 bit wav files on big endian CPUs
267 - added support for Ogg Vorbis sample files
268 - use loop markers from sample file if loop_start and loop_end are
269 not set in sfz file

414 incorrectly set to two. This caused silence in Cubase 5.
415 - save engine type (gig, sfz or sf2) in plugin state
416 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
417 64 bit Windows

427 loaded a second time (this time it's for Linux and Mac, previous
428 similar fix was for Windows)
429 - thread safety fixes for the instrument loading thread
430 - LV2: use the new lv2 package if present
431 - VST: try to open Fantasia automatically on Linux and Mac too (on
432 Linux, the Fantasia jar should be placed in <prefix>/share/java)
433 - VST: fixed crashes on Linux Ardour and EnergyXT
434 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
435 port and audio channel routing for DSSI plugins are now visible.
436 - LV2: use urid and atom extensions instead of deprecated uri-map
437 and event
438 - LV2: lv2 package 1.0 is now required to build the LV2 plugin
439 - LV2: changed number of output channels to 16 stereo, just like
440 the VST and AU plugins
441 - LV2: fixed save/restore of SFZ state (patch by David Robillard)
442 - LV2: made LV2 plugin buildable on Windows and Mac
443 - VST: implemented retrieval and switching of programs using the
444 sampler's internal MIDI instrument mapping system
445
446 * Instrument editor interface:

448 informations like the EngineChannel for which the instrument editor was
449 spawned for. This allows the instrument editors to interact more actively
450 with the sampler.
451
452 * MIDI driver:
453 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
454 the ALSA sequencer client name

458 - MME: removed compiler warning
459 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
460 which allows to retrieve the list of CoreMIDI clients / ports and to connect
461 to them a la JACK, via the usual sampler APIs
462 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
463 the driver will automatically connect to other CoreMIDI clients' ports
464 (e.g. external MIDI devices being attached to the Mac)
465 - added support for MIDI note on velocity filter
466 - CoreMIDI: fixed memory deallocation error
467 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
468 virtual keyboards in frontends / instrument editors being stuck.
469 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
470 - Implemented missing handling of MIDI "running status".
471 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
472 - MME bugfix: driver wasn't closed properly
473 - CoreMIDI: automatically connect to all input sources by default (driver
474 parameter "AUTO_BIND").

483 RT context.
484 - ASIO driver: removed compiler warnings
485 - CoreAudio: fixed minor error handling bug
486 - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

531 - Added support for auto completion by tab key.
532 - Show currently available auto completion while typing.
533 - Added support for browsing command history with up / down keys.

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

631 playing a note in a key group
632 - fixed erroneous error message piping in VoiceBase.h
633 (labelled "Disk stream not available in time")
634 - Update effects on sample rate & period size changes (to avoid
635 crashes and noise on such transitions).
636 - ignore missing LADSPA paths without ignoring valid LADSPA paths
637 (fixes #208)
638 - Fixed bug in LSCP grammar definition which caused a statement like
639 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
640 practically irrelevant, however it caused problems with the new LSCP
641 shell's auto completion feature).
642 - Fixed MIDI program change messages being ignored if quickly executed
643 after each other (fixes #231).
644
645 Version 1.0.0 (31 July 2009)
646
647 * packaging changes:
648 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

658 - minor fix in configure for mmsystem.h detection on MinGW
659 - Windows: look for editor plugins and Fantasia using base
660 directory of liblinuxsampler dll (look in the same directory and one
661 directory above)
662 - configure script fix: removed unconditional use of SSE
663 - fixed building with sqlite installed in a non-standard directory
664 - when cross-compiling, don't try to create instruments.db
665 - fix for new mingw-w64 version, which has usleep
666
667 * general changes:
668 - bugfix: on some POSIX systems instrument editor plugins refused to
669 load as we used a non-portable Linux specific struct field
670 (fixes bug #70, patch by Ronald Baljeu)
671 - fixed endless loop which occured when loading an instrument editor
672 plugin DLL on Windows systems failed
673 - fixed memory leaks that occurred when liblinuxsampler was unloaded
674 - optimized the SynchronizedConfig class so it doesn't wait
675 unnecessarily long after an update
676 - added support for notifying instrument editors on note-on / note-off
677 events (e.g. to highlight the pressed keys on the virtual keyboard
678 of gigedit)
679 - added support for triggering notes by instrument editors (see above)
680 - be verbose on DLL load errors (on Linux)
681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
682 is only used by very few systems, most pick the int math
683 implementation, which is usually faster)
684 - fixes for audio drivers with varying buffer sizes
685 - experimental support for running LinuxSampler as a DSSI, LV2 and
686 VST plugin
687 - notification events for stream/voice count statistics are now sent
688 only when there are actual changes

690 multi-core and multi-cpu systems
691 - maximum voices and disk streams can now be altered at runtime
692 - fixed CPU feature detection on x86_64 (maybe fixes #108)
693 - automatic stacktrace mechanism is now turned off by default and can
694 be switched on by command line option "--stacktrace" (the automatic
695 stacktrace mechanism seems to be broken on most systems at the moment)
696 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
697 a pointer to the launched InstrumentEditor object
698 - added optional 3rd party user data parameter for following
699 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
700 InstrumentEditor::Launch(),
701 InstrumentManager::LaunchInstrumentEditor()
702 - theoretical fix: made SynchronizedConfig follow C++0x memory
703 model more strictly
704 - fixes for using large audio device buffers
705 - Windows: add the installation directory to the DLL search path
706 when loading an editor plugin (solves problems with VST and
707 gigedit on systems with other GTK versions installed)
708 - updated linuxsampler man page
709
710 * audio driver:
711 - removed the nonsense audio channel constraint (which was hard coded to
712 max. 100 audio channels) for most audio drivers
713 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
714 opposed to the LSCP specs
715 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
716 reflected the wrong value
717 - fixed a memory management bug in ASIO driver
718 - Makefile fix: JACK_CFLAGS wasn't used
719 - JACK: use jack_client_open instead of the deprecated
720 jack_client_new

726 win64)
727 - VST: added support for sample rate and buffer size changes
728 - VST: close editor (Fantasia) when the VST is removed
729 - VST: avoid opening Fantasia more than once for each VST instance
730 - VST: export main function as "main" on Linux too (fix for
731 energyXT)
732 - VST: changed number of output channels from one stereo to 16
733 stereo
734 - added channel routing, fxsends and midi maps to the settings
735 stored in the plugin state
736 - performance optimization of AudioChannel::MixTo() and
737 AudioChannel::CopyTo() methods using GCC vector exensions
738 (if available)
739 - ASIO fixes: avoid initializing the device twice, avoid throwing
740 exception when getting parameters from a disconnected device
741
742 * MIDI driver:
743 - added JACK MIDI driver
744 - dispatch bank select as ordinary CC as well, the user might seriously
745 want to (mis)use it for some purpose ("fixed" in all current MIDI
746 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
747 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
748 CoreMidi or AU
749 - fixed mingw-w64 compilation error in MME driver
750 - made program change handling in MIDI thread real-time safe by
751 moving the logic to a non-RT thread
752 - fixed minor memory leak in ALSA driver
753
754 * instruments database:
755 - avoid time consuming samples scanning when adding instruments
756 to the instruments database

761 - work-around for missing fnmatch function on Windows to make
762 instrument database compilable
763 - added instrument database support on Windows
764 works with both standalone mode and VST plugin.
765 the instruments DB file is located in
766 %USERPROFILE%\.linuxsampler\instruments.db which allows different
767 databases for each windows user
768 if no DB is present it automatically creates the .linuxsampler subdir
769 and then creates an empty DB
770 - fixed recursive import, which was broken on Windows
771
772 * Gigasampler format engine:
773 - fixed a memory leak that could happen when a channel was deleted
774 while notes were playing
775 - made it possible to load an instrument even if the audio thread
776 isn't running
777 - added partial support for the "Controller Triggered" MIDI rule,
778 enough for piano gigs with pedal noise samples
779 - minor fix: only mark FX sends as being modified if really the
780 respective FX send MIDI controller was used
781 - added support for GM global device volume SysEx message
782 (can be selected at compile time to either apply globally to the
783 whole sampler [default] or only to the sampler channels that are
784 connected to the respective MIDI input port the SysEx message arrived
785 on)
786 - bugfix: notes triggered at position 0 in the audio buffer were
787 sometimes wrongly killed in the same buffer, causing no sound to
788 be played
789 - added support for chromatic / drumkit mode Roland GS Sysex message
790 which is usally used to switch a part between chromatic sounds and
791 drumkit sounds (as opposed to their common default setting of MIDI
792 part 10 being a drumkit part and all other ones chromatic parts), in
793 LS however one can switch between the first 16 MIDI instrument maps
794 defined for the sampler
795 - made it possible to create multiple sample channels even if the
796 audio thread isn't running
797 - fixed crash when removing channel with active voices (#116)
798 - bugfix: on sample reference changes (instrument editor), only
799 un-cache the respective sample if it's really not used by any
800 sampler engine anymore
801 - re-cache samples in case they were changed by an instrument editor,
802 e.g. when a sample was added while playing (#82)
803 - fixed hanging notes which occured when note-off event had the exact
804 same time stamp as the voice's note-on event and occured both in the
805 same audio fragment cycle (fixes bug #112)
806 - added support for the "fine tune" and "pitch bend range"
807 instrument-level gig parameters
808 - fixed minor artifacts in pitch bend handling
809 - added support for GS Reset SysEx message
810 - allow gig files to use unlimited downward pitch shifting
811 - added a limit check for upward pitch shifting
812 - bugfix: sometimes, when playing a note twice fast, the second
813 note was silent
814 - fixed crash happening when a pitch bend event arrived at the
815 same time a new instrument was loading
816
817 * LSCP server:
818 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
819 react on MIDI data arriving on certain sampler channels (so far only
820 Note-On and Note-Off events are sent via this LSCP event)
821 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
822 react on MIDI data arriving on certain MIDI input devices (so far only
823 Note-On and Note-Off events are sent via this LSCP event)
824 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
825 SET DB_INSTRUMENT FILE_PATH
826 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
827 frontends to send MIDI messages to specific sampler channel
828 - added two additional fields to GET FILE INSTRUMENT INFO command -
829 KEY_BINDINGS and KEYSWITCH_BINDINGS
830 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
831 was incorrect
832 - Optimized the retrieval of the MIDI instrument mappings
833 - added new LSCP command "SET VOICES" to globally alter the maximum
834 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
835 be triggered respectively
836 - added new LSCP command "SET STREAMS" to globally alter the maximum
837 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
838 which will be triggered respectively
839 - bugfix: retry if "select" returns EINTR (this fixes a crash when
840 a gigedit file dialog is opened)
841 - close all connections when LSCPServer is deleted
842 - hard close of all sockets on exit
843 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
844 driver
845
846 * Bug fixes:
847 - fixed a crash which occurs when removing a sampler channel waiting
848 to start instrument loading after another channel
849 - fixed a crash which occurs when removing a sampler channel with
850 instrument loading in progress (bug #113)
851 - fixed termination caused by uncaught exception when adding MIDI
852 instrument with PERSISTENT load mode
853 - fixed possible iterator invalidations when resetting the sampler
854 - fixed memory leaks when issuing the following LSCP commands:
855 GET AUDIO_OUTPUT_DRIVER INFO
856 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
857 GET MIDI_INPUT_DRIVER INFO
858 GET MIDI_INPUT_DRIVER_PARAMETER INFO
859 - fixed possible compilation error when sqlite is not present
860 - fixed orphaned pointers when setting maximum voices limit (bug #118)
861 - fixed crash when changing the audio output device of a sampler
862 channel with loaded instrument and start playing notes
863 - fixed endless loop in Engine::SuspendAll() (bug #120)
864 - fixed a low-level atomic load function that was broken on 64-bit
865 PowerPC, which probably could cause crashes on that platform
866 - fixed a memory management error which could cause a crash when a
867 plugin was unloaded
868 - bugfix: two private structs had the same name, which could cause
869 problems if the linker chose the wrong constructor
870 - fixed low-level ConditionServer usage bug that caused lockups on
871 Windows
872
873
874 Version 0.5.1 (6 December 2007)
875
876 * packaging changes:
877 - added autoconf checks for pthread library

879 glibc versions (see Gentoo bug report #194076)
880 - added autoconf checks for MS Windows
881
882 * general changes:
883 - bugfix: the thread used by an editor plugin didn't die when the
884 editor closed
885 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
886 out all the space. operator--() did not apply size_mask after
887 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
888 order to avoid problems with the _NonVolatileReader functions.
889 - bugfix: Stream.h: added a missing divide by BytesPerSample in
890 GetWriteSpace(). Since this function is currently only used in
891 the stream's qsort() compare function, it didn't trigger any
892 bugs.
893 - Resampler.h, Synthesizer.h: cubic interpolation now works in
894 24bit mode too. Faster method to read 24bit words on little
895 endian machines (x86): replaced 3 byte reads + shifts with a 1
896 unaligned 32bit read and shift
897 - experimental support for MS Windows (MIDI input via MME, AUDIO
898 output via ASIO)
899 - made handling of SIGINT signal (Ctrl-C) a bit more robust
900 - support for monitoring the total number of active disk streams
901 (new LSCP commands: GET TOTAL_STREAM_COUNT,
902 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
903
904 * AUDIO driver:
905 - added Windows ASIO low latency audio driver
906
907 * MIDI driver:
908 - added MME Windows MIDI driver
909
910 * LSCP server:
911 - added support for Windows style path / filenames, however with
912 forward slash path separators instead of backslash
913 (i.e. "C:/foo/bar.gig")
914 - allow naughty liblscp to send non-string device parameters within
915 apostrophes as well
916 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
917 "LIST FILE INSTRUMENTS <file>" and
918 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
919 about an arbitrary instrument file on the system where the sampler is
920 running on
921
922 Version 0.5.0 (15 October 2007)
923
924 * packaging changes:
925 - config.h is not going to be installed along with liblinuxsampler's
926 API header files anymore
927 - only the API relevant header (and source) files will be exported to
928 the Doxygen API documentation (explicitly listed in Doxyfile.in)
929 - added completely new XCode project files for Mac OSX which is now
930 capable to execute our autoconf environment, thus no need anymore
931 to maintain the compile time configuration file (osx/version.h) for
932 OSX manually (patch by Toshi Nagata)
933 - fixed buggy boolean --enable-foo / --disable-foo configure script
934 parameters
935 - global.h now only covers global definitions that are needed for the
936 C++ API header files, all implementation internal global definitions
937 are now in global_private.h
938 - atomic.h is not exposed to the C++ API anymore
939 - no need to include config.h anymore for using LS's API header files
940 - fixed warnings in API doc generation
941
942 * general changes:
943 - replaced the old, confusing MIDI program change mechanism by a
944 flexible MIDI instrument mapper which allows to map arbitrary
945 (MIDI bank, MIDI program) pairs with arbitrary
946 (engine type, instrument file, file index) triplets which will be
947 loaded on the respective channel when such MIDI program change
948 messages arrive, beside that, each entry allows to define a life-time
949 strategy for the instrument, so the user can define whether the
950 instrument should i.e. be permanently loaded (to be able to switch
951 quickly among sounds) or i.e. loaded just on demand when the
952 respective program change arrives (to safe RAM space), as well as a
953 global volume factor for each entry, so the user can adjust the volume
954 dynamic of his mapped instrument collection without having to modify
955 the instrument files, also one can manage arbitrary amount of such
956 MIDI instrument maps and assign each sampler channel individually
957 a certain map, so that i.e. separation of normal instruments and
958 drumkits is possible
959 - new notification events for tracking changes to audio/MIDI devices,
960 MIDI instrument maps, MIDI instruments, FX sends, global volume.
961 - sampler was limited to load max. 200 instruments in the background
962 due to a constant size RingBuffer FIFO which is now replaced by a
963 dynamic (unlimited) size std::list FIFO
964 - added FX sends, these allow to route audio signals to arbitrary audio
965 output channels for being processed by external effect processors
966 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
967 controllers
968 - global (sampler wide) volume can now be controlled at runtime
969 - Implemented new, improved notification system
970 - fixed compilation errors regarding OSX
971 (patch by Toshi Nagata)
972 - implemented instruments database
973 - added support for escape sequences to the instruments database
974 - added highly experimental support for on-the-fly instrument editing
975 within the sampler's process (by using instrument editor plugins),
976 you'll notice the new "Registered instrument editors:" message on
977 startup, added a new LSCP command:
978 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
979 to spawn a matching instrument editor for the instrument on the
980 given sampler channel, the plugin path can be overridden at compile
981 time with ./configure --enable-plugin-dir=/some/dir
982 - added experimental code for synchronizing instrument editors hosted
983 in the sampler's process to safely edit instruments while playing
984 without a crash (hopefully) by either suspending single regions
985 wherever possible or if unavoidable whole engine(s)
986 - fixed several issues in fundamental "Thread" class: set scheduling
987 policy and priority on thread level, set a minimum stack size for
988 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
989 threads simply inherited properties of starting thread instead of
990 setting their own policy and priority
991 - minor fix in our automatic stack trace mechanism on crashes, the
992 main process did not wait for the stack trace process to finish
993 its output
994 - fixed some minor memory leaks
995 - reenabled assembly features support, at the moment only for
996 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
997 - minor assembly fix in x86 features detection (don't use the PIC
998 register, to avoid relocations in the text segment at runtime)
999 - POSIX callback functions of Thread.h are hidden
1000
1001 * MIDI driver:
1002 - dispatch bank select (MSB and LSB) messages
1003
1004 * audio driver:
1005 - the ALSA audio output driver parameters now reflect the correct
1006 parameter value ranges for the respective selected sound card
1007 (patch by Till Wimmer, a bit fixed and extended)
1008
1009 * Gigasampler format engine:
1010 - if a filter is used and EG2 finishes before EG1, let the voice
1011 die when EG2 has finished (this fixes a problem with clicks and
1012 voice starvation for some gigs)
1013 - playback is no longer disabled during instrument loading
1014 - all notes playing on a channel that changes its instrument keep
1015 playing with the old instrument until they get a note off
1016 command
1017 - EG fix: a release value of zero could cause noises or crash
1018 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1019 - EG fine tuning: when attack is zero the EG starts at a level
1020 above max sustain level, which means that there is a decay phase
1021 even if sustain is 100%
1022 - more EG fixes: the level could sometimes go below zero and cause
1023 noises or crashes
1024 - minor fix of EGDecay (patch by Toshi Nagata)
1025 - fixed compiler error when --enable-override-filter-type was
1026 supplied to the configure script (fixes #46)
1027 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1028 instead of a fix value
1029 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1030 127 (solo mode) only kill voices if the respective mode really
1031 changed
1032
1033 * LSCP server:
1034 - fixed compile time error for old Bison versions
1035 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1036 - parser now supports extended ASCII character set
1037 (up to ASCII code 255, i.e. includes now umlauts and accents)
1038 - filename arguments in LSCP commands now allow to use escape
1039 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1040 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1041 code value like \xf2) (fixes bug #24)
1042 - the following LSCP commands now also support escape sequences for at
1043 least one of their text-based parameters (i.e. name, description):
1044 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1045 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1046 "SET DB_INSTRUMENT_DIRECTORY NAME",
1047 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1048 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1049 "FIND DB_INSTRUMENT_DIRECTORIES"
1050 - returns verbose syntax errors (line and column where syntax error
1051 occured, the unexpected character and the actually expected, possible
1052 character(s), the latter only if less than 5 possibilities)
1053 - made sure that LSCP syntax is not affected by gigedit locale
1054 settings
1055 - bugfix regarding strings parameter lists: all comma separated lists
1056 of strings were treated as being one string containing commas
1057 (fixes #57)
1058
1059 * Bug fixes:
1060 - fixed crash occurring on certain LSCP scripts (Bug 39)
1061 - another thread safety fix for lscp "load engine" and "set
1062 channel audio output device"
1063 - fixed a crash which occurs when reassigning the same engine
1064 on a sampler channel with connected MIDI device
1065 - fixed a crash which occurs when changing the number of ports of a MIDI
1066 device connected to a sampler channel to number less then or equal
1067 to the index of the port to which the sampler channel is connected.
1068 - The previous bindings were not been disconnected when altering
1069 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1070 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1071 - The active stream/voice count statistic was incorrect.
1072 - notification events were not been sent for some sampler
1073 channel changes
1074 - added default min and max values to restrict the number of allowed
1075 audio output channels and MIDI input ports
1076 - the connection to the PCM interface is now closed when destroying
1077 an audio output device
1078 - files with slash in their path or filename could not be loaded
1079
1080 * test cases:
1081 - updated and fixed (haven't been touched in a while)
1082
1083 Version 0.4.0 (24 November 2006)
1084
1085 * packaging changes:
1086 - changed deprecated copyright attribute to license; added ldconfig
1087 to post-(un)install steps; added devel package for liblinuxsampler;
1088 to linuxsampler.spec (RPM)
1089 - install necessary development header files for allowing 3rd party
1090 applications to link against liblinuxsampler
1091 - liblinuxsampler's API documentation can be generated with 'make docs'
1092 (Doxygen required)
1093 - added benchmark to automatically detect the best triangle LFO
1094 implementation (currently either an integer math solution or a
1095 di-harmonic approximation), automatic detection can be overriden
1096 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1097 configure script argument though (mandatory for cross-compilation)
1098 - do not automatically pick optimized gcc flags if the user already
1099 provided some on his own (as CXXFLAGS)
1100 - added compile time option to disable processing of All-Notes-Off MIDI
1101 messages
1102 - added compile time options to allow disabling the various audio and
1103 MIDI drivers
1104 - fixed automatic GCC CPU switch detection on PPC
1105 (patch by Ebrahim Mayat)
1106
1107 * Gigasampler format engine:
1108 - extensive synthesis optimization
1109 (reimplementation of EGs and LFO(s), removed synthesis parameter
1110 prerendering and the synthesis parameter matrix in general, splitting
1111 each audio fragment into subfragments now where each subfragment uses
1112 constant pitch and filter coefficients. The volume coefficient is
1113 linearly interpolated inside a subfragment, unless
1114 --disable-interpolate-volume is set.)
1115 - fine tuning of the EG modulation parameters
1116 - improved filter cutoff calculation by adding support for the
1117 following gig parameters: Cutoff freq (used when no cutoff
1118 controller is defined), Control invert, Minimum cutoff, Velocity
1119 curve and Velocity range. The keyboard tracking now scales
1120 cutoff frequency instead of resonance.
1121 - added support for gig parameter Resonance.
1122 - fixed bug in sysex handling (patch by Juan Linietsky)
1123 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1124 which can be overridden with --enable-global-attenuation
1125 - EG fixes: made the length of "attack hold" stage more
1126 accurate. Release stage can now start before attack stage
1127 ends. Cancel release didn't work when sustain was zero. Attack
1128 time now has a minimal value to prevent clicks.
1129 - fixed pitch changes larger than one octave
1130 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1131 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1132 all modes can be altered via standard GM messages, that is CC5 for
1133 altering portamento time, CC65 for enabling / disabling portamento
1134 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1135 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1136 parameter) and crossfade
1137 - added support for the "attenuation controller threshold" gig
1138 parameter
1139 - added smoothing of volume changes caused by control change
1140 messages
1141 - sample loop parameters are now taken from the DimensionRegion
1142 instead of the wave chunk
1143 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1144 not equal to a power of two
1145 - reimplementation of the filter algorithm. The new filter is more
1146 accurate and supports all gig filter types, including bandreject
1147 and lowpass turbo.
1148 - real support for 24 bit samples - samples are not truncated to
1149 16 bits anymore
1150 - support for aftertouch (channel pressure, not polyphonic
1151 aftertouch)
1152 - LFO1 behaviour fixed (dampening from max volume instead of
1153 amplifying from 0)
1154
1155 * LSCP server:
1156 - fixed application exit on broken pipe error (fixes bug #20)
1157 - fixed the notification messages delay due to lack of
1158 network activity (fixes bug #26)
1159 - fixed parser bug which occured on space(s) within device parameters
1160 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1161
1162 * audio driver:
1163 - added aRts audio output driver (by no means RT safe)
1164
1165 * MIDI driver:
1166 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1167 messages several times instead of once
1168 - API extension for MIDI drivers which already supply exact time stamps
1169 for events (i.e. for offline rendering based MIDI drivers)
1170 - added checks for bad MIDI data
1171
1172 * linuxsampler application:
1173 - show available sampler engine types on startup
1174
1175 * general changes:
1176 - support for muting sampler channels and solo mode of the same, two new
1177 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1178 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1179 introduced for this, the behavior is the same like on a mixer console
1180 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1181 --enable-process-muted-channels which can be used to enable the
1182 processing of muted channels.
1183 - support for sostenuto pedal
1184 - support for monitoring the total number of active voices
1185 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1186 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1187 - fixed some memory management errors
1188 - fixed some concurrency problems that could lead to crashes when
1189 LSCP commands were executed
1190 - fixed crash when instrument loading failed previously on the same
1191 sampler channel (fixes bug #36)
1192
1193 Version 0.3.3 (15 July 2005)
1194
1195 * packaging changes:
1196 - fixed compilation with gcc 4.0
1197
1198 * Gigasampler format engine:
1199 - LFO preprocessing was performed even though the respective LFO was
1200 disabled by the instrument patch (minor efficiency fix)
1201 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1202 for volume ramp downs in the same fragment (needed for current voice
1203 stealing implementation) then simply inform the user with a warning
1204 about possible click sounds and reduce the volume ramp down
1205 appropriately instead of cancelling the audio device connection
1206
1207 Version 0.3.2 (24 June 2005)
1208
1209 * packaging changes:
1210 - updated autotools build files to compile on OS X
1211 (conditional compilation of CoreMIDI and MidiShare drivers)
1212 - hand-crafted assembly optimization code can be disabled with
1213 './configure --disable-asm' (definitely not recommended)
1214 - fixed 'make dist' rule to include all necessary files
1215 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1216 (due to 'dist-bzip2' automake option)
1217
1218 * Gigasampler format engine:
1219 - support for the gig parameters for "release velocity response" curves
1220 - fine tuning of the EGADSR envelope
1221 - volume of release triggered samples now depends on note-on velocity,
1222 note length and gig parameter "release trigger decay" instead of
1223 note-off velocity.
1224 - revised voice stealing
1225 (fixes crash and endless loop caused by voice stealing)
1226 - don't reset scale tuning on instrument or audio output device change
1227 - handle key group conflicts right at the beginning of each fragment
1228 instead of when the respective voice is actually launched
1229 (fixes undefined behavior if stolen voices belonged to a key group -
1230 this case was followed by a "killed voice survived" error message)
1231 - fixed minor issue with null/silence samples
1232 (those stole voices even though they don't need a voice at all which
1233 resulted in "voice stealing didn't work out" messages)
1234 - don't reset volume, pan, pitch and MIDI controller values on
1235 instrument or audio output device change
1236
1237 * LSCP server:
1238 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1239 - fixed LSCP event "CHANNEL_INFO" notification
1240 (e.g. did not notify on volume changes or MIDI program change events)
1241
1242 * linuxsampler application:
1243 - added command line parameters --lscp-addr and --lscp-port to override
1244 default IP address and port of LSCP server
1245
1246 Version 0.3.1 (24 May 2005)
1247
1248 * initial release
