File size: 63375 byte(s)
* Automake: set environment variable GCC_COLORS=auto to allow GCC to
  auto detect whether it (sh/c)ould output its messages in color.
* Fixed behavior of built-in script function "ignore_event()".
* Bumped version (2.0.0.svn4).

1 Version SVN trunk (?)
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
6 * general changes:
7 - fixed printf type errors (mostly in debug messages)
8 - use unique_ptr instead of auto_ptr when building with C++11
9 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10 allowing to sort data efficiently in real-time safe manner.
11 - RTList class: added methods for moving/inserting elements to arbitrary
12 position within a list.
13 - RTList class: added method fromPtr() for creating an Iterator object from
14 a raw element pointer.
15 - Attempt to partly fix resetting engine channels vs. resetting engine, an
16 overall cleanup of the Reset*(), ConnectAudioDevice(),
17 DisconnectAudioDevice() API methods would still be desirable though,
18 because the current situation is still inconsistent and error prone.
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.
24 * packaging changes:
25 - removed unnecessary dependency to libuuid
26 (originated by libgig's usage of it)
27 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28 auto detect whether it (sh/c)ould output its messages in color.
30 * Real-time instrument scripts:
31 - Implemented scheduler for delayed MIDI events and for suspended scripts.
32 - Built-in script function "wait()": implemented support for function's
33 "duration-us" argument, thus scripts using this function are now
34 correctly resumed after the requested amount of microseconds.
35 - Built-in script function "play_note()": implemented support for
36 function's "duration-us" argument, thus notes triggered with this
37 argument are now correctly released after the requested amount of
38 microseconds.
39 - Fix: script events were not cleared when engine channel was reset,
40 potentially causing undefined behavior.
41 - Fixed crash which happened when trying to reference an undeclared
42 variable.
43 - Built-in script function "play_note()": Added support for passing
44 special value -1 for "duration-us" argument, which will cause the
45 triggered note to be released once the original note was released.
47 Version 2.0.0 (15 July 2015)
49 * packaging changes:
50 - fixed building with newer MinGW-w64
51 - Mac OS X: support the new dir for Core Audio SDK
52 - Mac OS X: fixed building outside source directory
53 - made sure all source files for hostplugins are included when
54 doing "make dist"
55 - removed empty directories left from the cvs to svn migration
56 - fixed compilation with gcc 4.6.1
57 - another "make dist" fix, for the LV2 plugin
58 - made --enable-pthread-testcancel default on Mac OS X
59 - minor Makefile fix for building lscpparser when build and source
60 directories are separate
61 - Mac OS X: made it possible to specify plugin installation dir to
62 configure
63 - Mac OS X: Makefile fix for the install-strip target
64 - fixed compilation with gcc 4.7
65 - fixed configure script error with old autoconf versions
66 - lsatomic.h: use gcc provided atomic functions if building with
67 gcc 4.7 and C++11
68 - modernized configure script
69 - fixed linkage error when building with
70 LDFLAGS="-Wl,--no-undefined" (#190)
71 - fixed compilation with Clang 3.2
72 - removed usage of deprecated Automake variable INCLUDES
73 - fixed building with C++11
74 - build fix: ChangeFlagRelaxed.h was missing in makefile
75 - build fix: libsndfile compiler flags were missing in some
76 makefiles
77 - fix for building with bison 3.0 (#202)
78 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
79 on the process's main thread
80 - fixed build error on newer MinGW
81 - support building with older jack versions
82 - support building with spaces in vst sdk path
83 - enabled automake 'subdir-objects' option and moved external
84 source references (vst, au, asio) from makefiles to cpp files,
85 in order to get rid of warnings from automake 1.14
87 * general changes:
88 - Refactoring: moved the independent code from
89 the Gigasampler format engine to base classes
90 - command line option '--profile' is currently disabled, since the
91 respective profiling code is currently broken
92 - Introduced support for optional environment variable
93 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
94 where the sampler shall look for instrument editor plugins
95 (patch by Luis Garrido, slightly modified).
96 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
97 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
98 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
99 note (in this implementation of the sampler its simply hard routed to
100 the 1st effect send of the sampler channel, no matter what the actual
101 effect type is)
102 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
103 note (in this implementation of the sampler its simply hard routed to
104 the 2nd effect send of the sampler channel, no matter what the actual
105 effect type is)
106 - implemented support for internal LADSPA effects
107 - raised limit of program change queue from 100 to 512
108 (as suggested by Alex Stone)
109 - implemented sine LFO, pulse LFO and saw LFO
110 - experimental support for per voice equalization
111 - added command line option --exec-after-init
112 - Introduced new C++ API method:
113 EngineChannel::InstrumentFileName(int index)
114 allowing to retrieve the whole list of files used for the loaded
115 instrument on an engine channel (a.k.a. part). Some GigaStudio
116 instruments for example are splitted over several files like
117 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
118 - Added new C++ API method Sampler::GetGlobalMaxVoices().
119 - Added new C++ API method Sampler::GetGlobalMaxStreams().
120 - Added new C++ API method Sampler::SetGlobalMaxVoices().
121 - Added new C++ API method Sampler::SetGlobalMaxStreams().
122 - Various "const" and "restrict" optimizations.
123 - all engines: add pan CC value to instrument pan parameter before
124 applying panning, instead of using two separate pan functions in
125 series (#182)
126 - added a lock guard class for exception safe mutex handling and
127 used it everywhere appropriate
128 - Immediately apply scale tuning changes to active voices.
129 - Exposed scale tuning to C++ API (along to the already existing standard
130 SysEx way).
131 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
132 and broken for ppc64. (Seq_cst loads and stores are actually not
133 used in LS, so the bug wasn't noticable.)
134 - lsatomic.h: added ARMv7 support
135 - Added support for multiple MIDI input ports per sampler channel (and
136 added various new C++ methods for this new feature / design change, old
137 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
138 as deprecated but are still there and should provide full behavior
139 backward compatibility).
140 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
141 unsafe and caused compilation error with clang 2.x).
142 - Bugfix: only process the latest MIDI program change event.
143 - Introducing the LSCP shell, which provides convenient control of the
144 sampler from the command line by providing LSCP aware features.
145 - VirtualMidiDevice: Added support for program change.
146 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
147 - VirtualMidiDevice: Added support for pitch bend.
148 - Aftertouch: extended API to explicitly handle channel pressure and
149 polyphonic key pressure events (so far polyphonic pressure was not
150 supported at all, and channel pressure was rerouted as CC128 but not
151 used so far).
152 - Added initial support for real-time instrument scripts. The script VM
153 code is shared by all sampler engine implemementations, however only the
154 gig file format currently provides support for storing instrument scripts
155 (as LinuxSampler extension to the original GigaStudio 4 format).
157 * Gigasampler format engine:
158 - implemented the "round robin keyboard" dimension
159 - fixed round robin and random dimensions for cases when number of
160 dimension zones is not a power of two
161 - made round robin use a counter for each region instead of each
162 key
163 - bugfix: pitch LFO controller "internal+aftertouch" was broken
164 - bugfix: filter keyboard tracking was broken
165 - filter performance fix (an unnecessary copy was made of the
166 filter parameters in each sub fragment)
167 - handle special case when pan parameter in gig file has max or
168 min value
169 - Exclusive Groups: don't ever stop voices of the same note,
170 doesn't sound naturally with a drumkit
171 - fixed EG1 modulation when attack or release is zero
172 - Fixed support for 'aftertouch' attenuation controller.
173 - Fixed crash that happened with velocity split sounds under certain
174 conditions (see also previous commit on libgig).
175 - fixed behaviour of filter LFO
177 * SFZ format engine:
178 - Initial implementation (not usable yet)
179 - added support for v2 multiple stage envelope generators
180 - added a fine-tuned v1 envelope generator instead of using the
181 one from the gig engine
182 - fixed memory leak and memory handling errors
183 - added support for trigger=first, trigger=legato and sw_previous
184 - allow non-numerical key values ("C#4" for example)

186 - fixed error when unloading instrument with same sample used by
187 multiple regions
188 - added some opcode aliases, like loopmode for loop_mode, to be
189 more compatible
190 - added support for trigger=release and rt_decay

198 - improved logic for sw_lokey/hikey/up/down/last
199 - added more v1 aliases to parser
200 - reduced memory usage for sfz data
201 - RT-safeness: avoid malloc in audio thread
202 - fixed a bug that could cause voice stealing to fail
203 - optimized sample lookup
204 - improved support for exclusive groups (group, off_by and
205 off_mode)
206 - added support for controller triggered regions (on_locc/on_hicc)
207 - added support for loop_mode=one_shot
208 - fixed playback of 16 bit wav files on big endian CPUs
209 - added support for Ogg Vorbis sample files
210 - use loop markers from sample file if loop_start and loop_end are
211 not set in sfz file

340 - added support for float and 32 bit sample files
342 * SoundFont format engine:
343 - Initial implementation (not usable yet)
344 - RT-safeness: avoid malloc in audio thread

352 - AU bugfix: failed to destroy its audio/MIDI devices
353 - Listen to all interfaces on Mac OS X (INADDR_ANY)
354 - VST bugfix: If the host called resume() before and after
355 changing sample rate or block size, the number of channels was
356 incorrectly set to two. This caused silence in Cubase 5.
357 - save engine type (gig, sfz or sf2) in plugin state
358 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
359 64 bit Windows

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

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

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

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

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

600 - minor fix in configure for mmsystem.h detection on MinGW
601 - Windows: look for editor plugins and Fantasia using base
602 directory of liblinuxsampler dll (look in the same directory and one
603 directory above)
604 - configure script fix: removed unconditional use of SSE
605 - fixed building with sqlite installed in a non-standard directory
606 - when cross-compiling, don't try to create instruments.db
607 - fix for new mingw-w64 version, which has usleep
609 * general changes:
610 - bugfix: on some POSIX systems instrument editor plugins refused to
611 load as we used a non-portable Linux specific struct field
612 (fixes bug #70, patch by Ronald Baljeu)
613 - fixed endless loop which occured when loading an instrument editor
614 plugin DLL on Windows systems failed
615 - fixed memory leaks that occurred when liblinuxsampler was unloaded
616 - optimized the SynchronizedConfig class so it doesn't wait
617 unnecessarily long after an update
618 - added support for notifying instrument editors on note-on / note-off
619 events (e.g. to highlight the pressed keys on the virtual keyboard
620 of gigedit)
621 - added support for triggering notes by instrument editors (see above)
622 - be verbose on DLL load errors (on Linux)
623 - fixed di-harmonic triangle LFO implementation (this LFO implementation
624 is only used by very few systems, most pick the int math
625 implementation, which is usually faster)
626 - fixes for audio drivers with varying buffer sizes
627 - experimental support for running LinuxSampler as a DSSI, LV2 and
628 VST plugin
629 - notification events for stream/voice count statistics are now sent
630 only when there are actual changes
631 - added memory ordering constraints to improve stability on
632 multi-core and multi-cpu systems
633 - maximum voices and disk streams can now be altered at runtime
634 - fixed CPU feature detection on x86_64 (maybe fixes #108)
635 - automatic stacktrace mechanism is now turned off by default and can
636 be switched on by command line option "--stacktrace" (the automatic
637 stacktrace mechanism seems to be broken on most systems at the moment)
638 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
639 a pointer to the launched InstrumentEditor object
640 - added optional 3rd party user data parameter for following
641 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
642 InstrumentEditor::Launch(),
643 InstrumentManager::LaunchInstrumentEditor()
644 - theoretical fix: made SynchronizedConfig follow C++0x memory
645 model more strictly
646 - fixes for using large audio device buffers
647 - Windows: add the installation directory to the DLL search path
648 when loading an editor plugin (solves problems with VST and
649 gigedit on systems with other GTK versions installed)
650 - updated linuxsampler man page
652 * audio driver:
653 - removed the nonsense audio channel constraint (which was hard coded to
654 max. 100 audio channels) for most audio drivers
655 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
656 opposed to the LSCP specs
657 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
658 reflected the wrong value
659 - fixed a memory management bug in ASIO driver
660 - Makefile fix: JACK_CFLAGS wasn't used
661 - JACK: use jack_client_open instead of the deprecated
662 jack_client_new
663 - added (experimental) CoreAudio driver
664 - applied old fixes to the ASIO driver that were included in the
665 previous binary release but accidentally never committed to CVS
666 (fixes #117)
667 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
668 win64)
669 - VST: added support for sample rate and buffer size changes
670 - VST: close editor (Fantasia) when the VST is removed
671 - VST: avoid opening Fantasia more than once for each VST instance
672 - VST: export main function as "main" on Linux too (fix for
673 energyXT)
674 - VST: changed number of output channels from one stereo to 16
675 stereo
676 - added channel routing, fxsends and midi maps to the settings
677 stored in the plugin state
678 - performance optimization of AudioChannel::MixTo() and
679 AudioChannel::CopyTo() methods using GCC vector exensions
680 (if available)
681 - ASIO fixes: avoid initializing the device twice, avoid throwing
682 exception when getting parameters from a disconnected device
684 * MIDI driver:
685 - added JACK MIDI driver
686 - dispatch bank select as ordinary CC as well, the user might seriously
687 want to (mis)use it for some purpose ("fixed" in all current MIDI
688 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
689 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
690 CoreMidi or AU
691 - fixed mingw-w64 compilation error in MME driver
692 - made program change handling in MIDI thread real-time safe by
693 moving the logic to a non-RT thread
694 - fixed minor memory leak in ALSA driver
696 * instruments database:
697 - avoid time consuming samples scanning when adding instruments
698 to the instruments database
699 - added support for handling lost files in the instruments database
700 - Implemented option for adding instruments in separate directories
701 in the instruments database
702 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
703 - work-around for missing fnmatch function on Windows to make
704 instrument database compilable
705 - added instrument database support on Windows
706 works with both standalone mode and VST plugin.
707 the instruments DB file is located in
708 %USERPROFILE%\.linuxsampler\instruments.db which allows different
709 databases for each windows user
710 if no DB is present it automatically creates the .linuxsampler subdir
711 and then creates an empty DB
712 - fixed recursive import, which was broken on Windows
714 * Gigasampler format engine:
715 - fixed a memory leak that could happen when a channel was deleted
716 while notes were playing
717 - made it possible to load an instrument even if the audio thread
718 isn't running
719 - added partial support for the "Controller Triggered" MIDI rule,
720 enough for piano gigs with pedal noise samples
721 - minor fix: only mark FX sends as being modified if really the
722 respective FX send MIDI controller was used
723 - added support for GM global device volume SysEx message
724 (can be selected at compile time to either apply globally to the
725 whole sampler [default] or only to the sampler channels that are
726 connected to the respective MIDI input port the SysEx message arrived
727 on)
728 - bugfix: notes triggered at position 0 in the audio buffer were
729 sometimes wrongly killed in the same buffer, causing no sound to
730 be played
731 - added support for chromatic / drumkit mode Roland GS Sysex message
732 which is usally used to switch a part between chromatic sounds and
733 drumkit sounds (as opposed to their common default setting of MIDI
734 part 10 being a drumkit part and all other ones chromatic parts), in
735 LS however one can switch between the first 16 MIDI instrument maps
736 defined for the sampler
737 - made it possible to create multiple sample channels even if the
738 audio thread isn't running
739 - fixed crash when removing channel with active voices (#116)
740 - bugfix: on sample reference changes (instrument editor), only
741 un-cache the respective sample if it's really not used by any
742 sampler engine anymore
743 - re-cache samples in case they were changed by an instrument editor,
744 e.g. when a sample was added while playing (#82)
745 - fixed hanging notes which occured when note-off event had the exact
746 same time stamp as the voice's note-on event and occured both in the
747 same audio fragment cycle (fixes bug #112)
748 - added support for the "fine tune" and "pitch bend range"
749 instrument-level gig parameters
750 - fixed minor artifacts in pitch bend handling
751 - added support for GS Reset SysEx message
752 - allow gig files to use unlimited downward pitch shifting
753 - added a limit check for upward pitch shifting
754 - bugfix: sometimes, when playing a note twice fast, the second
755 note was silent
756 - fixed crash happening when a pitch bend event arrived at the
757 same time a new instrument was loading
759 * LSCP server:
760 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
761 react on MIDI data arriving on certain sampler channels (so far only
762 Note-On and Note-Off events are sent via this LSCP event)
763 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
764 react on MIDI data arriving on certain MIDI input devices (so far only
765 Note-On and Note-Off events are sent via this LSCP event)
766 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
768 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
769 frontends to send MIDI messages to specific sampler channel
770 - added two additional fields to GET FILE INSTRUMENT INFO command -
772 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
773 was incorrect
774 - Optimized the retrieval of the MIDI instrument mappings
775 - added new LSCP command "SET VOICES" to globally alter the maximum
776 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
777 be triggered respectively
778 - added new LSCP command "SET STREAMS" to globally alter the maximum
779 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
780 which will be triggered respectively
781 - bugfix: retry if "select" returns EINTR (this fixes a crash when
782 a gigedit file dialog is opened)
783 - close all connections when LSCPServer is deleted
784 - hard close of all sockets on exit
785 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
786 driver
788 * Bug fixes:
789 - fixed a crash which occurs when removing a sampler channel waiting
790 to start instrument loading after another channel
791 - fixed a crash which occurs when removing a sampler channel with
792 instrument loading in progress (bug #113)
793 - fixed termination caused by uncaught exception when adding MIDI
794 instrument with PERSISTENT load mode
795 - fixed possible iterator invalidations when resetting the sampler
796 - fixed memory leaks when issuing the following LSCP commands:
801 - fixed possible compilation error when sqlite is not present
802 - fixed orphaned pointers when setting maximum voices limit (bug #118)
803 - fixed crash when changing the audio output device of a sampler
804 channel with loaded instrument and start playing notes
805 - fixed endless loop in Engine::SuspendAll() (bug #120)
806 - fixed a low-level atomic load function that was broken on 64-bit
807 PowerPC, which probably could cause crashes on that platform
808 - fixed a memory management error which could cause a crash when a
809 plugin was unloaded
810 - bugfix: two private structs had the same name, which could cause
811 problems if the linker chose the wrong constructor
812 - fixed low-level ConditionServer usage bug that caused lockups on
813 Windows
816 Version 0.5.1 (6 December 2007)
818 * packaging changes:
819 - added autoconf checks for pthread library
820 - added autoconf check for pthread bug found on certain NPTL-enabled
821 glibc versions (see Gentoo bug report #194076)
822 - added autoconf checks for MS Windows
824 * general changes:
825 - bugfix: the thread used by an editor plugin didn't die when the
826 editor closed
827 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
828 out all the space. operator--() did not apply size_mask after
829 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
830 order to avoid problems with the _NonVolatileReader functions.
831 - bugfix: Stream.h: added a missing divide by BytesPerSample in
832 GetWriteSpace(). Since this function is currently only used in
833 the stream's qsort() compare function, it didn't trigger any
834 bugs.
835 - Resampler.h, Synthesizer.h: cubic interpolation now works in
836 24bit mode too. Faster method to read 24bit words on little
837 endian machines (x86): replaced 3 byte reads + shifts with a 1
838 unaligned 32bit read and shift
839 - experimental support for MS Windows (MIDI input via MME, AUDIO
840 output via ASIO)
841 - made handling of SIGINT signal (Ctrl-C) a bit more robust
842 - support for monitoring the total number of active disk streams
843 (new LSCP commands: GET TOTAL_STREAM_COUNT,
846 * AUDIO driver:
847 - added Windows ASIO low latency audio driver
849 * MIDI driver:
850 - added MME Windows MIDI driver
852 * LSCP server:
853 - added support for Windows style path / filenames, however with
854 forward slash path separators instead of backslash
855 (i.e. "C:/foo/bar.gig")
856 - allow naughty liblscp to send non-string device parameters within
857 apostrophes as well
858 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
859 "LIST FILE INSTRUMENTS <file>" and
860 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
861 about an arbitrary instrument file on the system where the sampler is
862 running on
864 Version 0.5.0 (15 October 2007)
866 * packaging changes:
867 - config.h is not going to be installed along with liblinuxsampler's
868 API header files anymore
869 - only the API relevant header (and source) files will be exported to
870 the Doxygen API documentation (explicitly listed in Doxyfile.in)
871 - added completely new XCode project files for Mac OSX which is now
872 capable to execute our autoconf environment, thus no need anymore
873 to maintain the compile time configuration file (osx/version.h) for
874 OSX manually (patch by Toshi Nagata)
875 - fixed buggy boolean --enable-foo / --disable-foo configure script
876 parameters
877 - global.h now only covers global definitions that are needed for the
878 C++ API header files, all implementation internal global definitions
879 are now in global_private.h
880 - atomic.h is not exposed to the C++ API anymore
881 - no need to include config.h anymore for using LS's API header files
882 - fixed warnings in API doc generation
884 * general changes:
885 - replaced the old, confusing MIDI program change mechanism by a
886 flexible MIDI instrument mapper which allows to map arbitrary
887 (MIDI bank, MIDI program) pairs with arbitrary
888 (engine type, instrument file, file index) triplets which will be
889 loaded on the respective channel when such MIDI program change
890 messages arrive, beside that, each entry allows to define a life-time
891 strategy for the instrument, so the user can define whether the
892 instrument should i.e. be permanently loaded (to be able to switch
893 quickly among sounds) or i.e. loaded just on demand when the
894 respective program change arrives (to safe RAM space), as well as a
895 global volume factor for each entry, so the user can adjust the volume
896 dynamic of his mapped instrument collection without having to modify
897 the instrument files, also one can manage arbitrary amount of such
898 MIDI instrument maps and assign each sampler channel individually
899 a certain map, so that i.e. separation of normal instruments and
900 drumkits is possible
901 - new notification events for tracking changes to audio/MIDI devices,
902 MIDI instrument maps, MIDI instruments, FX sends, global volume.
903 - sampler was limited to load max. 200 instruments in the background
904 due to a constant size RingBuffer FIFO which is now replaced by a
905 dynamic (unlimited) size std::list FIFO
906 - added FX sends, these allow to route audio signals to arbitrary audio
907 output channels for being processed by external effect processors
908 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
909 controllers
910 - global (sampler wide) volume can now be controlled at runtime
911 - Implemented new, improved notification system
912 - fixed compilation errors regarding OSX
913 (patch by Toshi Nagata)
914 - implemented instruments database
915 - added support for escape sequences to the instruments database
916 - added highly experimental support for on-the-fly instrument editing
917 within the sampler's process (by using instrument editor plugins),
918 you'll notice the new "Registered instrument editors:" message on
919 startup, added a new LSCP command:
920 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
921 to spawn a matching instrument editor for the instrument on the
922 given sampler channel, the plugin path can be overridden at compile
923 time with ./configure --enable-plugin-dir=/some/dir
924 - added experimental code for synchronizing instrument editors hosted
925 in the sampler's process to safely edit instruments while playing
926 without a crash (hopefully) by either suspending single regions
927 wherever possible or if unavoidable whole engine(s)
928 - fixed several issues in fundamental "Thread" class: set scheduling
929 policy and priority on thread level, set a minimum stack size for
930 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
931 threads simply inherited properties of starting thread instead of
932 setting their own policy and priority
933 - minor fix in our automatic stack trace mechanism on crashes, the
934 main process did not wait for the stack trace process to finish
935 its output
936 - fixed some minor memory leaks
937 - reenabled assembly features support, at the moment only for
938 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
939 - minor assembly fix in x86 features detection (don't use the PIC
940 register, to avoid relocations in the text segment at runtime)
941 - POSIX callback functions of Thread.h are hidden
943 * MIDI driver:
944 - dispatch bank select (MSB and LSB) messages
946 * audio driver:
947 - the ALSA audio output driver parameters now reflect the correct
948 parameter value ranges for the respective selected sound card
949 (patch by Till Wimmer, a bit fixed and extended)
951 * Gigasampler format engine:
952 - if a filter is used and EG2 finishes before EG1, let the voice
953 die when EG2 has finished (this fixes a problem with clicks and
954 voice starvation for some gigs)
955 - playback is no longer disabled during instrument loading
956 - all notes playing on a channel that changes its instrument keep
957 playing with the old instrument until they get a note off
958 command
959 - EG fix: a release value of zero could cause noises or crash
960 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
961 - EG fine tuning: when attack is zero the EG starts at a level
962 above max sustain level, which means that there is a decay phase
963 even if sustain is 100%
964 - more EG fixes: the level could sometimes go below zero and cause
965 noises or crashes
966 - minor fix of EGDecay (patch by Toshi Nagata)
967 - fixed compiler error when --enable-override-filter-type was
968 supplied to the configure script (fixes #46)
969 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
970 instead of a fix value
971 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
972 127 (solo mode) only kill voices if the respective mode really
973 changed
975 * LSCP server:
976 - fixed compile time error for old Bison versions
977 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
978 - parser now supports extended ASCII character set
979 (up to ASCII code 255, i.e. includes now umlauts and accents)
980 - filename arguments in LSCP commands now allow to use escape
981 sequences, that is directly literal as one of: \', \", \\, \n, \r,
982 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
983 code value like \xf2) (fixes bug #24)
984 - the following LSCP commands now also support escape sequences for at
985 least one of their text-based parameters (i.e. name, description):
992 - returns verbose syntax errors (line and column where syntax error
993 occured, the unexpected character and the actually expected, possible
994 character(s), the latter only if less than 5 possibilities)
995 - made sure that LSCP syntax is not affected by gigedit locale
996 settings
997 - bugfix regarding strings parameter lists: all comma separated lists
998 of strings were treated as being one string containing commas
999 (fixes #57)
1001 * Bug fixes:
1002 - fixed crash occurring on certain LSCP scripts (Bug 39)
1003 - another thread safety fix for lscp "load engine" and "set
1004 channel audio output device"
1005 - fixed a crash which occurs when reassigning the same engine
1006 on a sampler channel with connected MIDI device
1007 - fixed a crash which occurs when changing the number of ports of a MIDI
1008 device connected to a sampler channel to number less then or equal
1009 to the index of the port to which the sampler channel is connected.
1010 - The previous bindings were not been disconnected when altering
1011 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1012 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1013 - The active stream/voice count statistic was incorrect.
1014 - notification events were not been sent for some sampler
1015 channel changes
1016 - added default min and max values to restrict the number of allowed
1017 audio output channels and MIDI input ports
1018 - the connection to the PCM interface is now closed when destroying
1019 an audio output device
1020 - files with slash in their path or filename could not be loaded
1022 * test cases:
1023 - updated and fixed (haven't been touched in a while)
1025 Version 0.4.0 (24 November 2006)
1027 * packaging changes:
1028 - changed deprecated copyright attribute to license; added ldconfig
1029 to post-(un)install steps; added devel package for liblinuxsampler;
1030 to linuxsampler.spec (RPM)
1031 - install necessary development header files for allowing 3rd party
1032 applications to link against liblinuxsampler
1033 - liblinuxsampler's API documentation can be generated with 'make docs'
1034 (Doxygen required)
1035 - added benchmark to automatically detect the best triangle LFO
1036 implementation (currently either an integer math solution or a
1037 di-harmonic approximation), automatic detection can be overriden
1038 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1039 configure script argument though (mandatory for cross-compilation)
1040 - do not automatically pick optimized gcc flags if the user already
1041 provided some on his own (as CXXFLAGS)
1042 - added compile time option to disable processing of All-Notes-Off MIDI
1043 messages
1044 - added compile time options to allow disabling the various audio and
1045 MIDI drivers
1046 - fixed automatic GCC CPU switch detection on PPC
1047 (patch by Ebrahim Mayat)
1049 * Gigasampler format engine:
1050 - extensive synthesis optimization
1051 (reimplementation of EGs and LFO(s), removed synthesis parameter
1052 prerendering and the synthesis parameter matrix in general, splitting
1053 each audio fragment into subfragments now where each subfragment uses
1054 constant pitch and filter coefficients. The volume coefficient is
1055 linearly interpolated inside a subfragment, unless
1056 --disable-interpolate-volume is set.)
1057 - fine tuning of the EG modulation parameters
1058 - improved filter cutoff calculation by adding support for the
1059 following gig parameters: Cutoff freq (used when no cutoff
1060 controller is defined), Control invert, Minimum cutoff, Velocity
1061 curve and Velocity range. The keyboard tracking now scales
1062 cutoff frequency instead of resonance.
1063 - added support for gig parameter Resonance.
1064 - fixed bug in sysex handling (patch by Juan Linietsky)
1065 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1066 which can be overridden with --enable-global-attenuation
1067 - EG fixes: made the length of "attack hold" stage more
1068 accurate. Release stage can now start before attack stage
1069 ends. Cancel release didn't work when sustain was zero. Attack
1070 time now has a minimal value to prevent clicks.
1071 - fixed pitch changes larger than one octave
1072 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1073 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1074 all modes can be altered via standard GM messages, that is CC5 for
1075 altering portamento time, CC65 for enabling / disabling portamento
1076 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1077 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1078 parameter) and crossfade
1079 - added support for the "attenuation controller threshold" gig
1080 parameter
1081 - added smoothing of volume changes caused by control change
1082 messages
1083 - sample loop parameters are now taken from the DimensionRegion
1084 instead of the wave chunk
1085 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1086 not equal to a power of two
1087 - reimplementation of the filter algorithm. The new filter is more
1088 accurate and supports all gig filter types, including bandreject
1089 and lowpass turbo.
1090 - real support for 24 bit samples - samples are not truncated to
1091 16 bits anymore
1092 - support for aftertouch (channel pressure, not polyphonic
1093 aftertouch)
1094 - LFO1 behaviour fixed (dampening from max volume instead of
1095 amplifying from 0)
1097 * LSCP server:
1098 - fixed application exit on broken pipe error (fixes bug #20)
1099 - fixed the notification messages delay due to lack of
1100 network activity (fixes bug #26)
1101 - fixed parser bug which occured on space(s) within device parameters
1104 * audio driver:
1105 - added aRts audio output driver (by no means RT safe)
1107 * MIDI driver:
1108 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1109 messages several times instead of once
1110 - API extension for MIDI drivers which already supply exact time stamps
1111 for events (i.e. for offline rendering based MIDI drivers)
1112 - added checks for bad MIDI data
1114 * linuxsampler application:
1115 - show available sampler engine types on startup
1117 * general changes:
1118 - support for muting sampler channels and solo mode of the same, two new
1119 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1120 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1121 introduced for this, the behavior is the same like on a mixer console
1122 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1123 --enable-process-muted-channels which can be used to enable the
1124 processing of muted channels.
1125 - support for sostenuto pedal
1126 - support for monitoring the total number of active voices
1129 - fixed some memory management errors
1130 - fixed some concurrency problems that could lead to crashes when
1131 LSCP commands were executed
1132 - fixed crash when instrument loading failed previously on the same
1133 sampler channel (fixes bug #36)
1135 Version 0.3.3 (15 July 2005)
1137 * packaging changes:
1138 - fixed compilation with gcc 4.0
1140 * Gigasampler format engine:
1141 - LFO preprocessing was performed even though the respective LFO was
1142 disabled by the instrument patch (minor efficiency fix)
1143 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1144 for volume ramp downs in the same fragment (needed for current voice
1145 stealing implementation) then simply inform the user with a warning
1146 about possible click sounds and reduce the volume ramp down
1147 appropriately instead of cancelling the audio device connection
1149 Version 0.3.2 (24 June 2005)
1151 * packaging changes:
1152 - updated autotools build files to compile on OS X
1153 (conditional compilation of CoreMIDI and MidiShare drivers)
1154 - hand-crafted assembly optimization code can be disabled with
1155 './configure --disable-asm' (definitely not recommended)
1156 - fixed 'make dist' rule to include all necessary files
1157 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1158 (due to 'dist-bzip2' automake option)
1160 * Gigasampler format engine:
1161 - support for the gig parameters for "release velocity response" curves
1162 - fine tuning of the EGADSR envelope
1163 - volume of release triggered samples now depends on note-on velocity,
1164 note length and gig parameter "release trigger decay" instead of
1165 note-off velocity.
1166 - revised voice stealing
1167 (fixes crash and endless loop caused by voice stealing)
1168 - don't reset scale tuning on instrument or audio output device change
1169 - handle key group conflicts right at the beginning of each fragment
1170 instead of when the respective voice is actually launched
1171 (fixes undefined behavior if stolen voices belonged to a key group -
1172 this case was followed by a "killed voice survived" error message)
1173 - fixed minor issue with null/silence samples
1174 (those stole voices even though they don't need a voice at all which
1175 resulted in "voice stealing didn't work out" messages)
1176 - don't reset volume, pan, pitch and MIDI controller values on
1177 instrument or audio output device change
1179 * LSCP server:
1180 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1181 - fixed LSCP event "CHANNEL_INFO" notification
1182 (e.g. did not notify on volume changes or MIDI program change events)
1184 * linuxsampler application:
1185 - added command line parameters --lscp-addr and --lscp-port to override
1186 default IP address and port of LSCP server
1188 Version 0.3.1 (24 May 2005)
1190 * initial release
