File size: 67201 byte(s)
* NKSP: Fixed all change_*() built-in script functions to apply their
  synthesis parameter changes immediately in case the respective note
  was triggered at the same time, instead of scheduling the parameter
  change, especially because it would cause some parameter types's
  changes either to be ramped (i.e. change_vol()) or other types even
  to have not effect at all (i.e. change_attack()).
* Bumped version (2.0.0.svn20).

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 - Fixed all change_*() built-in script functions to apply their
105 synthesis parameter changes immediately in case the respective note
106 was triggered at the same time, instead of scheduling the parameter
107 change, especially because it would cause some parameter types's
108 changes either to be ramped (i.e. change_vol()) or other types even
109 to have not effect at all (i.e. change_attack()).
110

149 in order to get rid of warnings from automake 1.14
150
151 * general changes:
152 - Refactoring: moved the independent code from
153 the Gigasampler format engine to base classes
154 - command line option '--profile' is currently disabled, since the
155 respective profiling code is currently broken
156 - Introduced support for optional environment variable
157 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
158 where the sampler shall look for instrument editor plugins
159 (patch by Luis Garrido, slightly modified).
160 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
161 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
162 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
163 note (in this implementation of the sampler its simply hard routed to
164 the 1st effect send of the sampler channel, no matter what the actual
165 effect type is)
166 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
167 note (in this implementation of the sampler its simply hard routed to
168 the 2nd effect send of the sampler channel, no matter what the actual
169 effect type is)
170 - implemented support for internal LADSPA effects
171 - raised limit of program change queue from 100 to 512
172 (as suggested by Alex Stone)
173 - implemented sine LFO, pulse LFO and saw LFO
174 - experimental support for per voice equalization
175 - added command line option --exec-after-init
176 - Introduced new C++ API method:
177 EngineChannel::InstrumentFileName(int index)
178 allowing to retrieve the whole list of files used for the loaded
179 instrument on an engine channel (a.k.a. part). Some GigaStudio
180 instruments for example are splitted over several files like
181 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
182 - Added new C++ API method Sampler::GetGlobalMaxVoices().
183 - Added new C++ API method Sampler::GetGlobalMaxStreams().
184 - Added new C++ API method Sampler::SetGlobalMaxVoices().
185 - Added new C++ API method Sampler::SetGlobalMaxStreams().
186 - Various "const" and "restrict" optimizations.
187 - all engines: add pan CC value to instrument pan parameter before
188 applying panning, instead of using two separate pan functions in
189 series (#182)
190 - added a lock guard class for exception safe mutex handling and
191 used it everywhere appropriate
192 - Immediately apply scale tuning changes to active voices.
193 - Exposed scale tuning to C++ API (along to the already existing standard
194 SysEx way).
195 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
196 and broken for ppc64. (Seq_cst loads and stores are actually not
197 used in LS, so the bug wasn't noticable.)
198 - lsatomic.h: added ARMv7 support
199 - Added support for multiple MIDI input ports per sampler channel (and
200 added various new C++ methods for this new feature / design change, old
201 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
202 as deprecated but are still there and should provide full behavior
203 backward compatibility).
204 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
205 unsafe and caused compilation error with clang 2.x).
206 - Bugfix: only process the latest MIDI program change event.
207 - Introducing the LSCP shell, which provides convenient control of the
208 sampler from the command line by providing LSCP aware features.
209 - VirtualMidiDevice: Added support for program change.
210 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
211 - VirtualMidiDevice: Added support for pitch bend.
212 - Aftertouch: extended API to explicitly handle channel pressure and
213 polyphonic key pressure events (so far polyphonic pressure was not
214 supported at all, and channel pressure was rerouted as CC128 but not
215 used so far).
216 - Added initial support for real-time instrument scripts. The script VM
217 code is shared by all sampler engine implemementations, however only the
218 gig file format currently provides support for storing instrument scripts
219 (as LinuxSampler extension to the original GigaStudio 4 format).
220
221 * Gigasampler format engine:
222 - implemented the "round robin keyboard" dimension
223 - fixed round robin and random dimensions for cases when number of
224 dimension zones is not a power of two

226 key
227 - bugfix: pitch LFO controller "internal+aftertouch" was broken
228 - bugfix: filter keyboard tracking was broken
229 - filter performance fix (an unnecessary copy was made of the
230 filter parameters in each sub fragment)
231 - handle special case when pan parameter in gig file has max or
232 min value
233 - Exclusive Groups: don't ever stop voices of the same note,
234 doesn't sound naturally with a drumkit
235 - fixed EG1 modulation when attack or release is zero
236 - Fixed support for 'aftertouch' attenuation controller.
237 - Fixed crash that happened with velocity split sounds under certain
238 conditions (see also previous commit on libgig).
239 - fixed behaviour of filter LFO
240
241 * SFZ format engine:

249 - "key" opcode now sets pitch_keycenter too
250 - fixed error when unloading instrument with same sample used by
251 multiple regions
252 - added some opcode aliases, like loopmode for loop_mode, to be
253 more compatible

271 - added support for loop_mode=one_shot
272 - fixed playback of 16 bit wav files on big endian CPUs
273 - added support for Ogg Vorbis sample files
274 - use loop markers from sample file if loop_start and loop_end are
275 not set in sfz file

405
406 * SoundFont format engine:

416 - AU bugfix: failed to destroy its audio/MIDI devices
417 - Listen to all interfaces on Mac OS X (INADDR_ANY)
418 - VST bugfix: If the host called resume() before and after
419 changing sample rate or block size, the number of channels was
420 incorrectly set to two. This caused silence in Cubase 5.
421 - save engine type (gig, sfz or sf2) in plugin state
422 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
423 64 bit Windows

433 loaded a second time (this time it's for Linux and Mac, previous
434 similar fix was for Windows)
435 - thread safety fixes for the instrument loading thread
436 - LV2: use the new lv2 package if present
437 - VST: try to open Fantasia automatically on Linux and Mac too (on
438 Linux, the Fantasia jar should be placed in <prefix>/share/java)
439 - VST: fixed crashes on Linux Ardour and EnergyXT
440 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
441 port and audio channel routing for DSSI plugins are now visible.
442 - LV2: use urid and atom extensions instead of deprecated uri-map
443 and event
444 - LV2: lv2 package 1.0 is now required to build the LV2 plugin
445 - LV2: changed number of output channels to 16 stereo, just like
446 the VST and AU plugins

448 - LV2: made LV2 plugin buildable on Windows and Mac
449 - VST: implemented retrieval and switching of programs using the
450 sampler's internal MIDI instrument mapping system
451
452 * Instrument editor interface:
453 - Changed instrument editor plugin interface, providing additional
454 informations like the EngineChannel for which the instrument editor was
455 spawned for. This allows the instrument editors to interact more actively
456 with the sampler.
457
458 * MIDI driver:
459 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
460 the ALSA sequencer client name

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

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

637 playing a note in a key group
638 - fixed erroneous error message piping in VoiceBase.h
639 (labelled "Disk stream not available in time")
640 - Update effects on sample rate & period size changes (to avoid
641 crashes and noise on such transitions).
642 - ignore missing LADSPA paths without ignoring valid LADSPA paths
643 (fixes #208)
644 - Fixed bug in LSCP grammar definition which caused a statement like
645 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
646 practically irrelevant, however it caused problems with the new LSCP
647 shell's auto completion feature).
648 - Fixed MIDI program change messages being ignored if quickly executed
649 after each other (fixes #231).
650
651 Version 1.0.0 (31 July 2009)
652
653 * packaging changes:
654 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

664 - minor fix in configure for mmsystem.h detection on MinGW
665 - Windows: look for editor plugins and Fantasia using base
666 directory of liblinuxsampler dll (look in the same directory and one
667 directory above)
668 - configure script fix: removed unconditional use of SSE
669 - fixed building with sqlite installed in a non-standard directory
670 - when cross-compiling, don't try to create instruments.db
671 - fix for new mingw-w64 version, which has usleep
672
673 * general changes:
674 - bugfix: on some POSIX systems instrument editor plugins refused to
675 load as we used a non-portable Linux specific struct field
676 (fixes bug #70, patch by Ronald Baljeu)
677 - fixed endless loop which occured when loading an instrument editor
678 plugin DLL on Windows systems failed
679 - fixed memory leaks that occurred when liblinuxsampler was unloaded
680 - optimized the SynchronizedConfig class so it doesn't wait
681 unnecessarily long after an update
682 - added support for notifying instrument editors on note-on / note-off
683 events (e.g. to highlight the pressed keys on the virtual keyboard
684 of gigedit)
685 - added support for triggering notes by instrument editors (see above)
686 - be verbose on DLL load errors (on Linux)
687 - fixed di-harmonic triangle LFO implementation (this LFO implementation
688 is only used by very few systems, most pick the int math
689 implementation, which is usually faster)
690 - fixes for audio drivers with varying buffer sizes
691 - experimental support for running LinuxSampler as a DSSI, LV2 and
692 VST plugin
693 - notification events for stream/voice count statistics are now sent
694 only when there are actual changes
695 - added memory ordering constraints to improve stability on
696 multi-core and multi-cpu systems
697 - maximum voices and disk streams can now be altered at runtime
698 - fixed CPU feature detection on x86_64 (maybe fixes #108)
699 - automatic stacktrace mechanism is now turned off by default and can
700 be switched on by command line option "--stacktrace" (the automatic
701 stacktrace mechanism seems to be broken on most systems at the moment)
702 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
703 a pointer to the launched InstrumentEditor object
704 - added optional 3rd party user data parameter for following
705 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
706 InstrumentEditor::Launch(),
707 InstrumentManager::LaunchInstrumentEditor()
708 - theoretical fix: made SynchronizedConfig follow C++0x memory
709 model more strictly
710 - fixes for using large audio device buffers
711 - Windows: add the installation directory to the DLL search path
712 when loading an editor plugin (solves problems with VST and
713 gigedit on systems with other GTK versions installed)
714 - updated linuxsampler man page
715
716 * audio driver:
717 - removed the nonsense audio channel constraint (which was hard coded to
718 max. 100 audio channels) for most audio drivers
719 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
720 opposed to the LSCP specs
721 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
722 reflected the wrong value
723 - fixed a memory management bug in ASIO driver
724 - Makefile fix: JACK_CFLAGS wasn't used
725 - JACK: use jack_client_open instead of the deprecated
726 jack_client_new

732 win64)
733 - VST: added support for sample rate and buffer size changes
734 - VST: close editor (Fantasia) when the VST is removed
735 - VST: avoid opening Fantasia more than once for each VST instance
736 - VST: export main function as "main" on Linux too (fix for
737 energyXT)
738 - VST: changed number of output channels from one stereo to 16
739 stereo
740 - added channel routing, fxsends and midi maps to the settings
741 stored in the plugin state
742 - performance optimization of AudioChannel::MixTo() and
743 AudioChannel::CopyTo() methods using GCC vector exensions
744 (if available)
745 - ASIO fixes: avoid initializing the device twice, avoid throwing
746 exception when getting parameters from a disconnected device
747
748 * MIDI driver:
749 - added JACK MIDI driver
750 - dispatch bank select as ordinary CC as well, the user might seriously
751 want to (mis)use it for some purpose ("fixed" in all current MIDI
752 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
753 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
754 CoreMidi or AU
755 - fixed mingw-w64 compilation error in MME driver
756 - made program change handling in MIDI thread real-time safe by
757 moving the logic to a non-RT thread
758 - fixed minor memory leak in ALSA driver
759
760 * instruments database:
761 - avoid time consuming samples scanning when adding instruments
762 to the instruments database

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

879
880 Version 0.5.1 (6 December 2007)
881
882 * packaging changes:
883 - added autoconf checks for pthread library
884 - added autoconf check for pthread bug found on certain NPTL-enabled
885 glibc versions (see Gentoo bug report #194076)
886 - added autoconf checks for MS Windows
887
888 * general changes:
889 - bugfix: the thread used by an editor plugin didn't die when the
890 editor closed
891 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
892 out all the space. operator--() did not apply size_mask after
893 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
894 order to avoid problems with the _NonVolatileReader functions.
895 - bugfix: Stream.h: added a missing divide by BytesPerSample in
896 GetWriteSpace(). Since this function is currently only used in
897 the stream's qsort() compare function, it didn't trigger any
898 bugs.
899 - Resampler.h, Synthesizer.h: cubic interpolation now works in
900 24bit mode too. Faster method to read 24bit words on little
901 endian machines (x86): replaced 3 byte reads + shifts with a 1
902 unaligned 32bit read and shift
903 - experimental support for MS Windows (MIDI input via MME, AUDIO
904 output via ASIO)
905 - made handling of SIGINT signal (Ctrl-C) a bit more robust
906 - support for monitoring the total number of active disk streams
907 (new LSCP commands: GET TOTAL_STREAM_COUNT,
908 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
909
910 * AUDIO driver:
911 - added Windows ASIO low latency audio driver
912
913 * MIDI driver:
914 - added MME Windows MIDI driver
915
916 * LSCP server:
917 - added support for Windows style path / filenames, however with
918 forward slash path separators instead of backslash
919 (i.e. "C:/foo/bar.gig")
920 - allow naughty liblscp to send non-string device parameters within
921 apostrophes as well
922 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
923 "LIST FILE INSTRUMENTS <file>" and
924 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
925 about an arbitrary instrument file on the system where the sampler is
926 running on
927
928 Version 0.5.0 (15 October 2007)
929
930 * packaging changes:
931 - config.h is not going to be installed along with liblinuxsampler's
932 API header files anymore
933 - only the API relevant header (and source) files will be exported to
934 the Doxygen API documentation (explicitly listed in Doxyfile.in)
935 - added completely new XCode project files for Mac OSX which is now
936 capable to execute our autoconf environment, thus no need anymore
937 to maintain the compile time configuration file (osx/version.h) for
938 OSX manually (patch by Toshi Nagata)
939 - fixed buggy boolean --enable-foo / --disable-foo configure script
940 parameters
941 - global.h now only covers global definitions that are needed for the
942 C++ API header files, all implementation internal global definitions
943 are now in global_private.h
944 - atomic.h is not exposed to the C++ API anymore
945 - no need to include config.h anymore for using LS's API header files
946 - fixed warnings in API doc generation
947
948 * general changes:
949 - replaced the old, confusing MIDI program change mechanism by a
950 flexible MIDI instrument mapper which allows to map arbitrary
951 (MIDI bank, MIDI program) pairs with arbitrary
952 (engine type, instrument file, file index) triplets which will be
953 loaded on the respective channel when such MIDI program change
954 messages arrive, beside that, each entry allows to define a life-time
955 strategy for the instrument, so the user can define whether the
956 instrument should i.e. be permanently loaded (to be able to switch
957 quickly among sounds) or i.e. loaded just on demand when the
958 respective program change arrives (to safe RAM space), as well as a
959 global volume factor for each entry, so the user can adjust the volume
960 dynamic of his mapped instrument collection without having to modify
961 the instrument files, also one can manage arbitrary amount of such
962 MIDI instrument maps and assign each sampler channel individually
963 a certain map, so that i.e. separation of normal instruments and
964 drumkits is possible
965 - new notification events for tracking changes to audio/MIDI devices,
966 MIDI instrument maps, MIDI instruments, FX sends, global volume.
967 - sampler was limited to load max. 200 instruments in the background
968 due to a constant size RingBuffer FIFO which is now replaced by a
969 dynamic (unlimited) size std::list FIFO
970 - added FX sends, these allow to route audio signals to arbitrary audio
971 output channels for being processed by external effect processors
972 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
973 controllers
974 - global (sampler wide) volume can now be controlled at runtime
975 - Implemented new, improved notification system
976 - fixed compilation errors regarding OSX
977 (patch by Toshi Nagata)
978 - implemented instruments database
979 - added support for escape sequences to the instruments database
980 - added highly experimental support for on-the-fly instrument editing
981 within the sampler's process (by using instrument editor plugins),
982 you'll notice the new "Registered instrument editors:" message on
983 startup, added a new LSCP command:
984 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
985 to spawn a matching instrument editor for the instrument on the
986 given sampler channel, the plugin path can be overridden at compile
987 time with ./configure --enable-plugin-dir=/some/dir
988 - added experimental code for synchronizing instrument editors hosted
989 in the sampler's process to safely edit instruments while playing
990 without a crash (hopefully) by either suspending single regions
991 wherever possible or if unavoidable whole engine(s)
992 - fixed several issues in fundamental "Thread" class: set scheduling
993 policy and priority on thread level, set a minimum stack size for
994 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
995 threads simply inherited properties of starting thread instead of
996 setting their own policy and priority
997 - minor fix in our automatic stack trace mechanism on crashes, the
998 main process did not wait for the stack trace process to finish
999 its output
1000 - fixed some minor memory leaks
1001 - reenabled assembly features support, at the moment only for
1002 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1003 - minor assembly fix in x86 features detection (don't use the PIC
1004 register, to avoid relocations in the text segment at runtime)
1005 - POSIX callback functions of Thread.h are hidden
1006
1007 * MIDI driver:
1008 - dispatch bank select (MSB and LSB) messages
1009
1010 * audio driver:
1011 - the ALSA audio output driver parameters now reflect the correct
1012 parameter value ranges for the respective selected sound card
1013 (patch by Till Wimmer, a bit fixed and extended)
1014
1015 * Gigasampler format engine:
1016 - if a filter is used and EG2 finishes before EG1, let the voice
1017 die when EG2 has finished (this fixes a problem with clicks and
1018 voice starvation for some gigs)
1019 - playback is no longer disabled during instrument loading
1020 - all notes playing on a channel that changes its instrument keep
1021 playing with the old instrument until they get a note off
1022 command
1023 - EG fix: a release value of zero could cause noises or crash
1024 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1025 - EG fine tuning: when attack is zero the EG starts at a level
1026 above max sustain level, which means that there is a decay phase
1027 even if sustain is 100%
1028 - more EG fixes: the level could sometimes go below zero and cause
1029 noises or crashes
1030 - minor fix of EGDecay (patch by Toshi Nagata)
1031 - fixed compiler error when --enable-override-filter-type was
1032 supplied to the configure script (fixes #46)
1033 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1034 instead of a fix value
1035 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1036 127 (solo mode) only kill voices if the respective mode really
1037 changed
1038
1039 * LSCP server:
1040 - fixed compile time error for old Bison versions
1041 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1042 - parser now supports extended ASCII character set
1043 (up to ASCII code 255, i.e. includes now umlauts and accents)
1044 - filename arguments in LSCP commands now allow to use escape
1045 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1046 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1047 code value like \xf2) (fixes bug #24)
1048 - the following LSCP commands now also support escape sequences for at
1049 least one of their text-based parameters (i.e. name, description):
1050 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1051 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1052 "SET DB_INSTRUMENT_DIRECTORY NAME",
1053 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1054 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1055 "FIND DB_INSTRUMENT_DIRECTORIES"
1056 - returns verbose syntax errors (line and column where syntax error
1057 occured, the unexpected character and the actually expected, possible
1058 character(s), the latter only if less than 5 possibilities)
1059 - made sure that LSCP syntax is not affected by gigedit locale
1060 settings
1061 - bugfix regarding strings parameter lists: all comma separated lists
1062 of strings were treated as being one string containing commas
1063 (fixes #57)
1064
1065 * Bug fixes:
1066 - fixed crash occurring on certain LSCP scripts (Bug 39)
1067 - another thread safety fix for lscp "load engine" and "set
1068 channel audio output device"
1069 - fixed a crash which occurs when reassigning the same engine
1070 on a sampler channel with connected MIDI device
1071 - fixed a crash which occurs when changing the number of ports of a MIDI
1072 device connected to a sampler channel to number less then or equal
1073 to the index of the port to which the sampler channel is connected.
1074 - The previous bindings were not been disconnected when altering
1075 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1076 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1077 - The active stream/voice count statistic was incorrect.
1078 - notification events were not been sent for some sampler
1079 channel changes
1080 - added default min and max values to restrict the number of allowed
1081 audio output channels and MIDI input ports
1082 - the connection to the PCM interface is now closed when destroying
1083 an audio output device
1084 - files with slash in their path or filename could not be loaded
1085
1086 * test cases:
1087 - updated and fixed (haven't been touched in a while)
1088
1089 Version 0.4.0 (24 November 2006)
1090
1091 * packaging changes:
1092 - changed deprecated copyright attribute to license; added ldconfig
1093 to post-(un)install steps; added devel package for liblinuxsampler;
1094 to linuxsampler.spec (RPM)
1095 - install necessary development header files for allowing 3rd party
1096 applications to link against liblinuxsampler
1097 - liblinuxsampler's API documentation can be generated with 'make docs'
1098 (Doxygen required)
1099 - added benchmark to automatically detect the best triangle LFO
1100 implementation (currently either an integer math solution or a
1101 di-harmonic approximation), automatic detection can be overriden
1102 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1103 configure script argument though (mandatory for cross-compilation)
1104 - do not automatically pick optimized gcc flags if the user already
1105 provided some on his own (as CXXFLAGS)
1106 - added compile time option to disable processing of All-Notes-Off MIDI
1107 messages
1108 - added compile time options to allow disabling the various audio and
1109 MIDI drivers
1110 - fixed automatic GCC CPU switch detection on PPC
1111 (patch by Ebrahim Mayat)
1112
1113 * Gigasampler format engine:
1114 - extensive synthesis optimization
1115 (reimplementation of EGs and LFO(s), removed synthesis parameter
1116 prerendering and the synthesis parameter matrix in general, splitting
1117 each audio fragment into subfragments now where each subfragment uses
1118 constant pitch and filter coefficients. The volume coefficient is
1119 linearly interpolated inside a subfragment, unless
1120 --disable-interpolate-volume is set.)
1121 - fine tuning of the EG modulation parameters
1122 - improved filter cutoff calculation by adding support for the
1123 following gig parameters: Cutoff freq (used when no cutoff
1124 controller is defined), Control invert, Minimum cutoff, Velocity
1125 curve and Velocity range. The keyboard tracking now scales
1126 cutoff frequency instead of resonance.
1127 - added support for gig parameter Resonance.
1128 - fixed bug in sysex handling (patch by Juan Linietsky)
1129 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1130 which can be overridden with --enable-global-attenuation
1131 - EG fixes: made the length of "attack hold" stage more
1132 accurate. Release stage can now start before attack stage
1133 ends. Cancel release didn't work when sustain was zero. Attack
1134 time now has a minimal value to prevent clicks.
1135 - fixed pitch changes larger than one octave
1136 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1137 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1138 all modes can be altered via standard GM messages, that is CC5 for
1139 altering portamento time, CC65 for enabling / disabling portamento
1140 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1141 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1142 parameter) and crossfade
1143 - added support for the "attenuation controller threshold" gig
1144 parameter
1145 - added smoothing of volume changes caused by control change
1146 messages
1147 - sample loop parameters are now taken from the DimensionRegion
1148 instead of the wave chunk
1149 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1150 not equal to a power of two
1151 - reimplementation of the filter algorithm. The new filter is more
1152 accurate and supports all gig filter types, including bandreject
1153 and lowpass turbo.
1154 - real support for 24 bit samples - samples are not truncated to
1155 16 bits anymore
1156 - support for aftertouch (channel pressure, not polyphonic
1157 aftertouch)
1158 - LFO1 behaviour fixed (dampening from max volume instead of
1159 amplifying from 0)
1160
1161 * LSCP server:
1162 - fixed application exit on broken pipe error (fixes bug #20)
1163 - fixed the notification messages delay due to lack of
1164 network activity (fixes bug #26)
1165 - fixed parser bug which occured on space(s) within device parameters
1166 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1167
1168 * audio driver:
1169 - added aRts audio output driver (by no means RT safe)
1170
1171 * MIDI driver:
1172 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1173 messages several times instead of once
1174 - API extension for MIDI drivers which already supply exact time stamps
1175 for events (i.e. for offline rendering based MIDI drivers)
1176 - added checks for bad MIDI data
1177
1178 * linuxsampler application:
1179 - show available sampler engine types on startup
1180
1181 * general changes:
1182 - support for muting sampler channels and solo mode of the same, two new
1183 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1184 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1185 introduced for this, the behavior is the same like on a mixer console
1186 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1187 --enable-process-muted-channels which can be used to enable the
1188 processing of muted channels.
1189 - support for sostenuto pedal
1190 - support for monitoring the total number of active voices
1191 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1192 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1193 - fixed some memory management errors
1194 - fixed some concurrency problems that could lead to crashes when
1195 LSCP commands were executed
1196 - fixed crash when instrument loading failed previously on the same
1197 sampler channel (fixes bug #36)
1198
1199 Version 0.3.3 (15 July 2005)
1200
1201 * packaging changes:
1202 - fixed compilation with gcc 4.0
1203
1204 * Gigasampler format engine:
1205 - LFO preprocessing was performed even though the respective LFO was
1206 disabled by the instrument patch (minor efficiency fix)
1207 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1208 for volume ramp downs in the same fragment (needed for current voice
1209 stealing implementation) then simply inform the user with a warning
1210 about possible click sounds and reduce the volume ramp down
1211 appropriately instead of cancelling the audio device connection
1212
1213 Version 0.3.2 (24 June 2005)
1214
1215 * packaging changes:
1216 - updated autotools build files to compile on OS X
1217 (conditional compilation of CoreMIDI and MidiShare drivers)
1218 - hand-crafted assembly optimization code can be disabled with
1219 './configure --disable-asm' (definitely not recommended)
1220 - fixed 'make dist' rule to include all necessary files
1221 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1222 (due to 'dist-bzip2' automake option)
1223
1224 * Gigasampler format engine:
1225 - support for the gig parameters for "release velocity response" curves
1226 - fine tuning of the EGADSR envelope
1227 - volume of release triggered samples now depends on note-on velocity,
1228 note length and gig parameter "release trigger decay" instead of
1229 note-off velocity.
1230 - revised voice stealing
1231 (fixes crash and endless loop caused by voice stealing)
1232 - don't reset scale tuning on instrument or audio output device change
1233 - handle key group conflicts right at the beginning of each fragment
1234 instead of when the respective voice is actually launched
1235 (fixes undefined behavior if stolen voices belonged to a key group -
1236 this case was followed by a "killed voice survived" error message)
1237 - fixed minor issue with null/silence samples
1238 (those stole voices even though they don't need a voice at all which
1239 resulted in "voice stealing didn't work out" messages)
1240 - don't reset volume, pan, pitch and MIDI controller values on
1241 instrument or audio output device change
1242
1243 * LSCP server:
1244 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1245 - fixed LSCP event "CHANNEL_INFO" notification
1246 (e.g. did not notify on volume changes or MIDI program change events)
1247
1248 * linuxsampler application:
1249 - added command line parameters --lscp-addr and --lscp-port to override
1250 default IP address and port of LSCP server
1251
1252 Version 0.3.1 (24 May 2005)
1253
1254 * initial release
