File size: 65552 byte(s)
* NKSP: Implemented built-in script variable "$KSP_TIMER".
* NKSP: Implemented built-in script variable "$NKSP_REAL_TIMER".
* NKSP: Implemented built-in script variable "$NKSP_PERF_TIMER".
* NKSP: Implemented built-in script variable "$ENGINE_UPTIME".
* Bumped version (2.0.0.svn14).

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
84 Version 2.0.0 (15 July 2015)
85

107 LDFLAGS="-Wl,--no-undefined" (#190)
108 - fixed compilation with Clang 3.2
109 - removed usage of deprecated Automake variable INCLUDES

119 - support building with spaces in vst sdk path
120 - enabled automake 'subdir-objects' option and moved external
121 source references (vst, au, asio) from makefiles to cpp files,
122 in order to get rid of warnings from automake 1.14
123
124 * general changes:
125 - Refactoring: moved the independent code from
126 the Gigasampler format engine to base classes
127 - command line option '--profile' is currently disabled, since the
128 respective profiling code is currently broken
129 - Introduced support for optional environment variable
130 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
131 where the sampler shall look for instrument editor plugins
132 (patch by Luis Garrido, slightly modified).
133 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
134 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
135 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
136 note (in this implementation of the sampler its simply hard routed to
137 the 1st effect send of the sampler channel, no matter what the actual
138 effect type is)
139 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
140 note (in this implementation of the sampler its simply hard routed to
141 the 2nd effect send of the sampler channel, no matter what the actual
142 effect type is)
143 - implemented support for internal LADSPA effects
144 - raised limit of program change queue from 100 to 512
145 (as suggested by Alex Stone)
146 - implemented sine LFO, pulse LFO and saw LFO
147 - experimental support for per voice equalization
148 - added command line option --exec-after-init
149 - Introduced new C++ API method:
150 EngineChannel::InstrumentFileName(int index)
151 allowing to retrieve the whole list of files used for the loaded
152 instrument on an engine channel (a.k.a. part). Some GigaStudio
153 instruments for example are splitted over several files like
154 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
155 - Added new C++ API method Sampler::GetGlobalMaxVoices().
156 - Added new C++ API method Sampler::GetGlobalMaxStreams().
157 - Added new C++ API method Sampler::SetGlobalMaxVoices().
158 - Added new C++ API method Sampler::SetGlobalMaxStreams().
159 - Various "const" and "restrict" optimizations.
160 - all engines: add pan CC value to instrument pan parameter before
161 applying panning, instead of using two separate pan functions in
162 series (#182)
163 - added a lock guard class for exception safe mutex handling and
164 used it everywhere appropriate
165 - Immediately apply scale tuning changes to active voices.
166 - Exposed scale tuning to C++ API (along to the already existing standard
167 SysEx way).
168 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
169 and broken for ppc64. (Seq_cst loads and stores are actually not
170 used in LS, so the bug wasn't noticable.)
171 - lsatomic.h: added ARMv7 support
172 - Added support for multiple MIDI input ports per sampler channel (and
173 added various new C++ methods for this new feature / design change, old
174 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
175 as deprecated but are still there and should provide full behavior
176 backward compatibility).
177 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
178 unsafe and caused compilation error with clang 2.x).
179 - Bugfix: only process the latest MIDI program change event.
180 - Introducing the LSCP shell, which provides convenient control of the
181 sampler from the command line by providing LSCP aware features.
182 - VirtualMidiDevice: Added support for program change.
183 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
184 - VirtualMidiDevice: Added support for pitch bend.
185 - Aftertouch: extended API to explicitly handle channel pressure and
186 polyphonic key pressure events (so far polyphonic pressure was not
187 supported at all, and channel pressure was rerouted as CC128 but not
188 used so far).
189 - Added initial support for real-time instrument scripts. The script VM
190 code is shared by all sampler engine implemementations, however only the
191 gig file format currently provides support for storing instrument scripts
192 (as LinuxSampler extension to the original GigaStudio 4 format).
193
194 * Gigasampler format engine:
195 - implemented the "round robin keyboard" dimension
196 - fixed round robin and random dimensions for cases when number of
197 dimension zones is not a power of two
198 - made round robin use a counter for each region instead of each
199 key
200 - bugfix: pitch LFO controller "internal+aftertouch" was broken
201 - bugfix: filter keyboard tracking was broken
202 - filter performance fix (an unnecessary copy was made of the
203 filter parameters in each sub fragment)
204 - handle special case when pan parameter in gig file has max or
205 min value
206 - Exclusive Groups: don't ever stop voices of the same note,
207 doesn't sound naturally with a drumkit
208 - fixed EG1 modulation when attack or release is zero
209 - Fixed support for 'aftertouch' attenuation controller.
210 - Fixed crash that happened with velocity split sounds under certain
211 conditions (see also previous commit on libgig).
212 - fixed behaviour of filter LFO
213
214 * SFZ format engine:

244 - added support for loop_mode=one_shot
245 - fixed playback of 16 bit wav files on big endian CPUs
246 - added support for Ogg Vorbis sample files
247 - use loop markers from sample file if loop_start and loop_end are
248 not set in sfz file

376 - bugfix: line numbers in error messages were wrong after "#include"
377 - added support for float and 32 bit sample files
378
379 * SoundFont format engine:
380 - Initial implementation (not usable yet)
381 - RT-safeness: avoid malloc in audio thread
382 - fixed a bug that could cause voice stealing to fail
383 - fine-tuned amplitude EG (by switching from gig to sfz EG)
384 - initial implementation of Vibrato LFO and Modulation LFO
385 - initial implementation of cutoff filter
386 - use linear decay and release for filter and pitch EG
387
388 * Host plugins (VST, AU, LV2, DSSI):
389 - AU bugfix: failed to destroy its audio/MIDI devices
390 - Listen to all interfaces on Mac OS X (INADDR_ANY)
391 - VST bugfix: If the host called resume() before and after
392 changing sample rate or block size, the number of channels was
393 incorrectly set to two. This caused silence in Cubase 5.

395 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
396 64 bit Windows

398 stereo
399 - VST: made it possible to build the VST plugin for Mac
400 - AU: link AU plugin dynamically if --disable-shared isn't
401 specified
402 - LV2 "state" extension support (patch by David Robillard)
403 - VST bugfix: instrument loading hang and crashed the host when
404 the plugin was loaded a second time (#174)
405 - plugin bugfix: instrument loading hang when the plugin was
406 loaded a second time (this time it's for Linux and Mac, previous
407 similar fix was for Windows)
408 - thread safety fixes for the instrument loading thread
409 - LV2: use the new lv2 package if present
410 - VST: try to open Fantasia automatically on Linux and Mac too (on
411 Linux, the Fantasia jar should be placed in <prefix>/share/java)
412 - VST: fixed crashes on Linux Ardour and EnergyXT

427 informations like the EngineChannel for which the instrument editor was
428 spawned for. This allows the instrument editors to interact more actively
429 with the sampler.
430
431 * MIDI driver:
432 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
433 the ALSA sequencer client name

437 - MME: removed compiler warning
438 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
439 which allows to retrieve the list of CoreMIDI clients / ports and to connect
440 to them a la JACK, via the usual sampler APIs

442 the driver will automatically connect to other CoreMIDI clients' ports
443 (e.g. external MIDI devices being attached to the Mac)
444 - added support for MIDI note on velocity filter
445 - CoreMIDI: fixed memory deallocation error
446 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
447 virtual keyboards in frontends / instrument editors being stuck.

510 - Added support for auto completion by tab key.
511 - Show currently available auto completion while typing.
512 - Added support for browsing command history with up / down keys.

570
571 * Bug fixes:

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

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

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

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

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