Mon Jul 18 09:42:28 2016 UTC (7 years, 8 months ago) by schoenebeck
File size: 67529 byte(s)
* NKSP: Implemented built-in script function "sh_left()".
* NKSP: Implemented built-in script function "sh_right()".
* Bumped version (2.0.0.svn22).

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 - All engines: Increased ramp speed of volume smoother and pan smoother
28 (while slow rate of crossfade smoother is preserved) to allow quick
29 volume and pan changes by instrument scripts for instance.
30
31 * packaging changes:
32 - removed unnecessary dependency to libuuid
33 (originated by libgig's usage of it)
34 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
35 auto detect whether it (sh/c)ould output its messages in color.
36
37 * Real-time instrument scripts:
38 - Implemented scheduler for delayed MIDI events and for suspended scripts.
39 - Built-in script function "wait()": implemented support for function's
40 "duration-us" argument, thus scripts using this function are now
41 correctly resumed after the requested amount of microseconds.
42 - Built-in script function "play_note()": implemented support for
43 function's "duration-us" argument, thus notes triggered with this
44 argument are now correctly released after the requested amount of
45 microseconds.
46 - Fix: script events were not cleared when engine channel was reset,
47 potentially causing undefined behavior.
48 - Fixed crash which happened when trying to reference an undeclared
49 variable.
50 - Built-in script function "play_note()": Added support for passing
51 special value -1 for "duration-us" argument, which will cause the
52 triggered note to be released once the original note was released.
53 - Instrument script classes now exported with the liblinuxsampler C++ API.
54 - Added new API method ScriptVM::syntaxHighlighting() which provides
55 a convenient syntax highlighting backend for external instrument
56 script editor applications.
57 - Added new C++ API class "ScriptVMFactory".
58 - Extended parser issues to provide not only first line and first
59 column, but also last line and last column of issue (thus marking
60 the precise span of the issue within the source code).
61 - Reload script automatically after being modified by an instrument
62 editor.
63 - NKSP language grammar correction: allow empty event handler bodies
64 like "on note end on".
65 - Implemented built-in script function "change_vol()".
66 - Implemented built-in script function "change_tune()".
67 - Implemented built-in script function "change_pan()".
68 - Implemented built-in script function "change_cutoff()".
69 - Implemented built-in script function "change_reso()".
70 - Implemented built-in script function "event_status()".
71 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
72 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
73 "event_status()" function.
74 - NKSP language: Added support for bitwise operators ".or.", ".and."
75 and ".not.".
76 - NKSP language scanner: Fixed IDs matching to require at least one
77 character (i.e. when matching function names or variable names).
78 - NKSP language scanner: disabled unusued rules.
79 - Fixed behavior of play_note() and note_off() functions which must
80 be distinguished engine internally from "real" MIDI note on/off
81 events in order to avoid misbehaviors like hanging notes.
82 - Implemented built-in script variable "$KSP_TIMER".
83 - Implemented built-in script variable "$NKSP_REAL_TIMER".
84 - Implemented built-in script variable "$NKSP_PERF_TIMER".
85 - Implemented built-in script variable "$ENGINE_UPTIME".
86 - Implemented built-in script function "inc()".
87 - Implemented built-in script function "dec()".
88 - NKSP language fix: division expressions were evaluated too often.
89 - NKSP language fix: string concatenation operator was right
90 associative instead of left (to right).
91 - NKSP language correction: allow empty statements in entire language
92 (i.e. "if end if").
93 - Implemented built-in script function "stop_wait()".
94 - Implemented built-in script variable "$NI_CALLBACK_ID".
95 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
96 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
97 - Added support for read-only built-in variables (respectively
98 handled by the script parser).
99 - Added built-in script constant "$NI_CB_TYPE_INIT".
100 - Added built-in script constant "$NI_CB_TYPE_NOTE".
101 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
102 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
103 - NKSP Language: Added support for user defined script functions.
104 - Implemented built-in script function "change_attack()".
105 - Implemented built-in script function "change_decay()".
106 - Implemented built-in script function "change_release()".
107 - Fixed all change_*() built-in script functions to apply their
108 synthesis parameter changes immediately in case the respective note
109 was triggered at the same time, instead of scheduling the parameter
110 change, especially because it would cause some parameter types's
111 changes either to be ramped (i.e. change_vol()) or other types even
112 to have not effect at all (i.e. change_attack()).
113 - Implemented built-in script function "sh_left()".
114 - Implemented built-in script function "sh_right()".
115

148 on the process's main thread
149 - fixed build error on newer MinGW
150 - support building with older jack versions

154 in order to get rid of warnings from automake 1.14
155
156 * general changes:
157 - Refactoring: moved the independent code from
158 the Gigasampler format engine to base classes
159 - command line option '--profile' is currently disabled, since the
160 respective profiling code is currently broken
161 - Introduced support for optional environment variable
162 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
163 where the sampler shall look for instrument editor plugins
164 (patch by Luis Garrido, slightly modified).
165 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
166 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
167 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
168 note (in this implementation of the sampler its simply hard routed to
169 the 1st effect send of the sampler channel, no matter what the actual
170 effect type is)
171 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
172 note (in this implementation of the sampler its simply hard routed to
173 the 2nd effect send of the sampler channel, no matter what the actual
174 effect type is)
175 - implemented support for internal LADSPA effects
176 - raised limit of program change queue from 100 to 512
177 (as suggested by Alex Stone)
178 - implemented sine LFO, pulse LFO and saw LFO
179 - experimental support for per voice equalization
180 - added command line option --exec-after-init
181 - Introduced new C++ API method:
182 EngineChannel::InstrumentFileName(int index)
183 allowing to retrieve the whole list of files used for the loaded
184 instrument on an engine channel (a.k.a. part). Some GigaStudio
185 instruments for example are splitted over several files like
186 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
187 - Added new C++ API method Sampler::GetGlobalMaxVoices().
188 - Added new C++ API method Sampler::GetGlobalMaxStreams().
189 - Added new C++ API method Sampler::SetGlobalMaxVoices().
190 - Added new C++ API method Sampler::SetGlobalMaxStreams().
191 - Various "const" and "restrict" optimizations.
192 - all engines: add pan CC value to instrument pan parameter before
193 applying panning, instead of using two separate pan functions in
194 series (#182)
195 - added a lock guard class for exception safe mutex handling and
196 used it everywhere appropriate
197 - Immediately apply scale tuning changes to active voices.
198 - Exposed scale tuning to C++ API (along to the already existing standard
199 SysEx way).
200 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
201 and broken for ppc64. (Seq_cst loads and stores are actually not
202 used in LS, so the bug wasn't noticable.)
203 - lsatomic.h: added ARMv7 support
204 - Added support for multiple MIDI input ports per sampler channel (and
205 added various new C++ methods for this new feature / design change, old
206 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
207 as deprecated but are still there and should provide full behavior
208 backward compatibility).
209 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
210 unsafe and caused compilation error with clang 2.x).
211 - Bugfix: only process the latest MIDI program change event.
212 - Introducing the LSCP shell, which provides convenient control of the
213 sampler from the command line by providing LSCP aware features.
214 - VirtualMidiDevice: Added support for program change.
215 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
216 - VirtualMidiDevice: Added support for pitch bend.
217 - Aftertouch: extended API to explicitly handle channel pressure and
218 polyphonic key pressure events (so far polyphonic pressure was not
219 supported at all, and channel pressure was rerouted as CC128 but not
220 used so far).
221 - Added initial support for real-time instrument scripts. The script VM
222 code is shared by all sampler engine implemementations, however only the
223 gig file format currently provides support for storing instrument scripts
224 (as LinuxSampler extension to the original GigaStudio 4 format).
225
226 * Gigasampler format engine:
227 - implemented the "round robin keyboard" dimension
228 - fixed round robin and random dimensions for cases when number of
229 dimension zones is not a power of two
230 - made round robin use a counter for each region instead of each
231 key
232 - bugfix: pitch LFO controller "internal+aftertouch" was broken
233 - bugfix: filter keyboard tracking was broken
234 - filter performance fix (an unnecessary copy was made of the
235 filter parameters in each sub fragment)
236 - handle special case when pan parameter in gig file has max or
237 min value
238 - Exclusive Groups: don't ever stop voices of the same note,
239 doesn't sound naturally with a drumkit
240 - fixed EG1 modulation when attack or release is zero
241 - Fixed support for 'aftertouch' attenuation controller.
242 - Fixed crash that happened with velocity split sounds under certain
243 conditions (see also previous commit on libgig).
244 - fixed behaviour of filter LFO
245
246 * SFZ format engine:

253 - allow non-numerical key values ("C#4" for example)
254 - "key" opcode now sets pitch_keycenter too
255 - fixed error when unloading instrument with same sample used by
256 multiple regions
257 - added some opcode aliases, like loopmode for loop_mode, to be
258 more compatible
259 - added support for trigger=release and rt_decay

276 - added support for loop_mode=one_shot
277 - fixed playback of 16 bit wav files on big endian CPUs
278 - added support for Ogg Vorbis sample files
279 - use loop markers from sample file if loop_start and loop_end are
280 not set in sfz file
281 - implemeted filters. Filter types: lowpass, bandpass, bandreject
282 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
283 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
284 cutoff_cc, cutoff_chanaft.
285 - bugfix: zero ampeg_sustain didn't work

404 - added support for "#include" instruction
405 (modified patch which was originally posted by Sergey on LS mailing list)
406 - bugfix: generation of velocity curves etc should not be done
407 after each "#include", only after the main file is parsed
408 - bugfix: line numbers in error messages were wrong after "#include"
409 - added support for float and 32 bit sample files
410
411 * SoundFont format engine:
412 - Initial implementation (not usable yet)
413 - RT-safeness: avoid malloc in audio thread

421 - AU bugfix: failed to destroy its audio/MIDI devices
422 - Listen to all interfaces on Mac OS X (INADDR_ANY)
423 - VST bugfix: If the host called resume() before and after
424 changing sample rate or block size, the number of channels was
425 incorrectly set to two. This caused silence in Cubase 5.
426 - save engine type (gig, sfz or sf2) in plugin state
427 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
428 64 bit Windows

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

453 - LV2: made LV2 plugin buildable on Windows and Mac
454 - VST: implemented retrieval and switching of programs using the
455 sampler's internal MIDI instrument mapping system
456
457 * Instrument editor interface:
458 - Changed instrument editor plugin interface, providing additional
459 informations like the EngineChannel for which the instrument editor was
460 spawned for. This allows the instrument editors to interact more actively
461 with the sampler.
462
463 * MIDI driver:
464 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
465 the ALSA sequencer client name

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

542 - Added support for auto completion by tab key.
543 - Show currently available auto completion while typing.
544 - Added support for browsing command history with up / down keys.

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

642 playing a note in a key group
643 - fixed erroneous error message piping in VoiceBase.h
644 (labelled "Disk stream not available in time")
645 - Update effects on sample rate & period size changes (to avoid
646 crashes and noise on such transitions).
647 - ignore missing LADSPA paths without ignoring valid LADSPA paths
648 (fixes #208)
649 - Fixed bug in LSCP grammar definition which caused a statement like
650 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
651 practically irrelevant, however it caused problems with the new LSCP
652 shell's auto completion feature).
653 - Fixed MIDI program change messages being ignored if quickly executed
654 after each other (fixes #231).
655
656 Version 1.0.0 (31 July 2009)
657
658 * packaging changes:
659 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

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

737 win64)
738 - VST: added support for sample rate and buffer size changes
739 - VST: close editor (Fantasia) when the VST is removed
740 - VST: avoid opening Fantasia more than once for each VST instance
741 - VST: export main function as "main" on Linux too (fix for
742 energyXT)
743 - VST: changed number of output channels from one stereo to 16
744 stereo
745 - added channel routing, fxsends and midi maps to the settings
746 stored in the plugin state
747 - performance optimization of AudioChannel::MixTo() and
748 AudioChannel::CopyTo() methods using GCC vector exensions
749 (if available)
750 - ASIO fixes: avoid initializing the device twice, avoid throwing
751 exception when getting parameters from a disconnected device
752
753 * MIDI driver:
754 - added JACK MIDI driver
755 - dispatch bank select as ordinary CC as well, the user might seriously
756 want to (mis)use it for some purpose ("fixed" in all current MIDI
757 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
758 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
759 CoreMidi or AU
760 - fixed mingw-w64 compilation error in MME driver
761 - made program change handling in MIDI thread real-time safe by
762 moving the logic to a non-RT thread
763 - fixed minor memory leak in ALSA driver
764
765 * instruments database:
766 - avoid time consuming samples scanning when adding instruments
767 to the instruments database

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

868 GET MIDI_INPUT_DRIVER INFO
869 GET MIDI_INPUT_DRIVER_PARAMETER INFO
870 - fixed possible compilation error when sqlite is not present
871 - fixed orphaned pointers when setting maximum voices limit (bug #118)
872 - fixed crash when changing the audio output device of a sampler
873 channel with loaded instrument and start playing notes
874 - fixed endless loop in Engine::SuspendAll() (bug #120)
875 - fixed a low-level atomic load function that was broken on 64-bit
876 PowerPC, which probably could cause crashes on that platform
877 - fixed a memory management error which could cause a crash when a
878 plugin was unloaded
879 - bugfix: two private structs had the same name, which could cause
880 problems if the linker chose the wrong constructor
881 - fixed low-level ConditionServer usage bug that caused lockups on
882 Windows
883
884
885 Version 0.5.1 (6 December 2007)
886
887 * packaging changes:
888 - added autoconf checks for pthread library
889 - added autoconf check for pthread bug found on certain NPTL-enabled
890 glibc versions (see Gentoo bug report #194076)
891 - added autoconf checks for MS Windows
892
893 * general changes:
894 - bugfix: the thread used by an editor plugin didn't die when the
895 editor closed
896 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
897 out all the space. operator--() did not apply size_mask after
898 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
899 order to avoid problems with the _NonVolatileReader functions.
900 - bugfix: Stream.h: added a missing divide by BytesPerSample in
901 GetWriteSpace(). Since this function is currently only used in
902 the stream's qsort() compare function, it didn't trigger any
903 bugs.
904 - Resampler.h, Synthesizer.h: cubic interpolation now works in
905 24bit mode too. Faster method to read 24bit words on little
906 endian machines (x86): replaced 3 byte reads + shifts with a 1
907 unaligned 32bit read and shift
908 - experimental support for MS Windows (MIDI input via MME, AUDIO
909 output via ASIO)
910 - made handling of SIGINT signal (Ctrl-C) a bit more robust
911 - support for monitoring the total number of active disk streams
912 (new LSCP commands: GET TOTAL_STREAM_COUNT,
913 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
914
915 * AUDIO driver:
916 - added Windows ASIO low latency audio driver
917
918 * MIDI driver:
919 - added MME Windows MIDI driver
920
921 * LSCP server:
922 - added support for Windows style path / filenames, however with
923 forward slash path separators instead of backslash
924 (i.e. "C:/foo/bar.gig")
925 - allow naughty liblscp to send non-string device parameters within
926 apostrophes as well
927 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
928 "LIST FILE INSTRUMENTS <file>" and
929 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
930 about an arbitrary instrument file on the system where the sampler is
931 running on
932
933 Version 0.5.0 (15 October 2007)
934
935 * packaging changes:
936 - config.h is not going to be installed along with liblinuxsampler's
937 API header files anymore
938 - only the API relevant header (and source) files will be exported to
939 the Doxygen API documentation (explicitly listed in Doxyfile.in)
940 - added completely new XCode project files for Mac OSX which is now
941 capable to execute our autoconf environment, thus no need anymore
942 to maintain the compile time configuration file (osx/version.h) for
943 OSX manually (patch by Toshi Nagata)
944 - fixed buggy boolean --enable-foo / --disable-foo configure script
945 parameters
946 - global.h now only covers global definitions that are needed for the
947 C++ API header files, all implementation internal global definitions
948 are now in global_private.h
949 - atomic.h is not exposed to the C++ API anymore
950 - no need to include config.h anymore for using LS's API header files
951 - fixed warnings in API doc generation
952
953 * general changes:
954 - replaced the old, confusing MIDI program change mechanism by a
955 flexible MIDI instrument mapper which allows to map arbitrary
956 (MIDI bank, MIDI program) pairs with arbitrary
957 (engine type, instrument file, file index) triplets which will be
958 loaded on the respective channel when such MIDI program change
959 messages arrive, beside that, each entry allows to define a life-time
960 strategy for the instrument, so the user can define whether the
961 instrument should i.e. be permanently loaded (to be able to switch
962 quickly among sounds) or i.e. loaded just on demand when the
963 respective program change arrives (to safe RAM space), as well as a
964 global volume factor for each entry, so the user can adjust the volume
965 dynamic of his mapped instrument collection without having to modify
966 the instrument files, also one can manage arbitrary amount of such
967 MIDI instrument maps and assign each sampler channel individually
968 a certain map, so that i.e. separation of normal instruments and
969 drumkits is possible
970 - new notification events for tracking changes to audio/MIDI devices,
971 MIDI instrument maps, MIDI instruments, FX sends, global volume.
972 - sampler was limited to load max. 200 instruments in the background
973 due to a constant size RingBuffer FIFO which is now replaced by a
974 dynamic (unlimited) size std::list FIFO
975 - added FX sends, these allow to route audio signals to arbitrary audio
976 output channels for being processed by external effect processors
977 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
978 controllers
979 - global (sampler wide) volume can now be controlled at runtime
980 - Implemented new, improved notification system
981 - fixed compilation errors regarding OSX
982 (patch by Toshi Nagata)
983 - implemented instruments database
984 - added support for escape sequences to the instruments database
985 - added highly experimental support for on-the-fly instrument editing
986 within the sampler's process (by using instrument editor plugins),
987 you'll notice the new "Registered instrument editors:" message on
988 startup, added a new LSCP command:
989 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
990 to spawn a matching instrument editor for the instrument on the
991 given sampler channel, the plugin path can be overridden at compile
992 time with ./configure --enable-plugin-dir=/some/dir
993 - added experimental code for synchronizing instrument editors hosted
994 in the sampler's process to safely edit instruments while playing
995 without a crash (hopefully) by either suspending single regions
996 wherever possible or if unavoidable whole engine(s)
997 - fixed several issues in fundamental "Thread" class: set scheduling
998 policy and priority on thread level, set a minimum stack size for
999 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1000 threads simply inherited properties of starting thread instead of
1001 setting their own policy and priority
1002 - minor fix in our automatic stack trace mechanism on crashes, the
1003 main process did not wait for the stack trace process to finish
1004 its output
1005 - fixed some minor memory leaks
1006 - reenabled assembly features support, at the moment only for
1007 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1008 - minor assembly fix in x86 features detection (don't use the PIC
1009 register, to avoid relocations in the text segment at runtime)
1010 - POSIX callback functions of Thread.h are hidden
1011
1012 * MIDI driver:
1013 - dispatch bank select (MSB and LSB) messages
1014
1015 * audio driver:
1016 - the ALSA audio output driver parameters now reflect the correct
1017 parameter value ranges for the respective selected sound card
1018 (patch by Till Wimmer, a bit fixed and extended)
1019
1020 * Gigasampler format engine:
1021 - if a filter is used and EG2 finishes before EG1, let the voice
1022 die when EG2 has finished (this fixes a problem with clicks and
1023 voice starvation for some gigs)
1024 - playback is no longer disabled during instrument loading
1025 - all notes playing on a channel that changes its instrument keep
1026 playing with the old instrument until they get a note off
1027 command
1028 - EG fix: a release value of zero could cause noises or crash
1029 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1030 - EG fine tuning: when attack is zero the EG starts at a level
1031 above max sustain level, which means that there is a decay phase
1032 even if sustain is 100%
1033 - more EG fixes: the level could sometimes go below zero and cause
1034 noises or crashes
1035 - minor fix of EGDecay (patch by Toshi Nagata)
1036 - fixed compiler error when --enable-override-filter-type was
1037 supplied to the configure script (fixes #46)
1038 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1039 instead of a fix value
1040 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1041 127 (solo mode) only kill voices if the respective mode really
1042 changed
1043
1044 * LSCP server:
1045 - fixed compile time error for old Bison versions
1046 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1047 - parser now supports extended ASCII character set
1048 (up to ASCII code 255, i.e. includes now umlauts and accents)
1049 - filename arguments in LSCP commands now allow to use escape
1050 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1051 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1052 code value like \xf2) (fixes bug #24)
1053 - the following LSCP commands now also support escape sequences for at
1054 least one of their text-based parameters (i.e. name, description):
1055 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1056 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1057 "SET DB_INSTRUMENT_DIRECTORY NAME",
1058 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1059 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1060 "FIND DB_INSTRUMENT_DIRECTORIES"
1061 - returns verbose syntax errors (line and column where syntax error
1062 occured, the unexpected character and the actually expected, possible
1063 character(s), the latter only if less than 5 possibilities)
1064 - made sure that LSCP syntax is not affected by gigedit locale
1065 settings
1066 - bugfix regarding strings parameter lists: all comma separated lists
1067 of strings were treated as being one string containing commas
1068 (fixes #57)
1069
1070 * Bug fixes:
1071 - fixed crash occurring on certain LSCP scripts (Bug 39)
1072 - another thread safety fix for lscp "load engine" and "set
1073 channel audio output device"
1074 - fixed a crash which occurs when reassigning the same engine
1075 on a sampler channel with connected MIDI device
1076 - fixed a crash which occurs when changing the number of ports of a MIDI
1077 device connected to a sampler channel to number less then or equal
1078 to the index of the port to which the sampler channel is connected.
1079 - The previous bindings were not been disconnected when altering
1080 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1081 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1082 - The active stream/voice count statistic was incorrect.
1083 - notification events were not been sent for some sampler
1084 channel changes
1085 - added default min and max values to restrict the number of allowed
1086 audio output channels and MIDI input ports
1087 - the connection to the PCM interface is now closed when destroying
1088 an audio output device
1089 - files with slash in their path or filename could not be loaded
1090
1091 * test cases:
1092 - updated and fixed (haven't been touched in a while)
1093
1094 Version 0.4.0 (24 November 2006)
1095
1096 * packaging changes:
1097 - changed deprecated copyright attribute to license; added ldconfig
1098 to post-(un)install steps; added devel package for liblinuxsampler;
1099 to linuxsampler.spec (RPM)
1100 - install necessary development header files for allowing 3rd party
1101 applications to link against liblinuxsampler
1102 - liblinuxsampler's API documentation can be generated with 'make docs'
1103 (Doxygen required)
1104 - added benchmark to automatically detect the best triangle LFO
1105 implementation (currently either an integer math solution or a
1106 di-harmonic approximation), automatic detection can be overriden
1107 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1108 configure script argument though (mandatory for cross-compilation)
1109 - do not automatically pick optimized gcc flags if the user already
1110 provided some on his own (as CXXFLAGS)
1111 - added compile time option to disable processing of All-Notes-Off MIDI
1112 messages
1113 - added compile time options to allow disabling the various audio and
1114 MIDI drivers
1115 - fixed automatic GCC CPU switch detection on PPC
1116 (patch by Ebrahim Mayat)
1117
1118 * Gigasampler format engine:
1119 - extensive synthesis optimization
1120 (reimplementation of EGs and LFO(s), removed synthesis parameter
1121 prerendering and the synthesis parameter matrix in general, splitting
1122 each audio fragment into subfragments now where each subfragment uses
1123 constant pitch and filter coefficients. The volume coefficient is
1124 linearly interpolated inside a subfragment, unless
1125 --disable-interpolate-volume is set.)
1126 - fine tuning of the EG modulation parameters
1127 - improved filter cutoff calculation by adding support for the
1128 following gig parameters: Cutoff freq (used when no cutoff
1129 controller is defined), Control invert, Minimum cutoff, Velocity
1130 curve and Velocity range. The keyboard tracking now scales
1131 cutoff frequency instead of resonance.
1132 - added support for gig parameter Resonance.
1133 - fixed bug in sysex handling (patch by Juan Linietsky)
1134 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1135 which can be overridden with --enable-global-attenuation
1136 - EG fixes: made the length of "attack hold" stage more
1137 accurate. Release stage can now start before attack stage
1138 ends. Cancel release didn't work when sustain was zero. Attack
1139 time now has a minimal value to prevent clicks.
1140 - fixed pitch changes larger than one octave
1141 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1142 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1143 all modes can be altered via standard GM messages, that is CC5 for
1144 altering portamento time, CC65 for enabling / disabling portamento
1145 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1146 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1147 parameter) and crossfade
1148 - added support for the "attenuation controller threshold" gig
1149 parameter
1150 - added smoothing of volume changes caused by control change
1151 messages
1152 - sample loop parameters are now taken from the DimensionRegion
1153 instead of the wave chunk
1154 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1155 not equal to a power of two
1156 - reimplementation of the filter algorithm. The new filter is more
1157 accurate and supports all gig filter types, including bandreject
1158 and lowpass turbo.
1159 - real support for 24 bit samples - samples are not truncated to
1160 16 bits anymore
1161 - support for aftertouch (channel pressure, not polyphonic
1162 aftertouch)
1163 - LFO1 behaviour fixed (dampening from max volume instead of
1164 amplifying from 0)
1165
1166 * LSCP server:
1167 - fixed application exit on broken pipe error (fixes bug #20)
1168 - fixed the notification messages delay due to lack of
1169 network activity (fixes bug #26)
1170 - fixed parser bug which occured on space(s) within device parameters
1171 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1172
1173 * audio driver:
1174 - added aRts audio output driver (by no means RT safe)
1175
1176 * MIDI driver:
1177 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1178 messages several times instead of once
1179 - API extension for MIDI drivers which already supply exact time stamps
1180 for events (i.e. for offline rendering based MIDI drivers)
1181 - added checks for bad MIDI data
1182
1183 * linuxsampler application:
1184 - show available sampler engine types on startup
1185
1186 * general changes:
1187 - support for muting sampler channels and solo mode of the same, two new
1188 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1189 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1190 introduced for this, the behavior is the same like on a mixer console
1191 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1192 --enable-process-muted-channels which can be used to enable the
1193 processing of muted channels.
1194 - support for sostenuto pedal
1195 - support for monitoring the total number of active voices
1196 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1197 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1198 - fixed some memory management errors
1199 - fixed some concurrency problems that could lead to crashes when
1200 LSCP commands were executed
1201 - fixed crash when instrument loading failed previously on the same
1202 sampler channel (fixes bug #36)
1203
1204 Version 0.3.3 (15 July 2005)
1205
1206 * packaging changes:
1207 - fixed compilation with gcc 4.0
1208
1209 * Gigasampler format engine:
1210 - LFO preprocessing was performed even though the respective LFO was
1211 disabled by the instrument patch (minor efficiency fix)
1212 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1213 for volume ramp downs in the same fragment (needed for current voice
1214 stealing implementation) then simply inform the user with a warning
1215 about possible click sounds and reduce the volume ramp down
1216 appropriately instead of cancelling the audio device connection
1217
1218 Version 0.3.2 (24 June 2005)
1219
1220 * packaging changes:
1221 - updated autotools build files to compile on OS X
1222 (conditional compilation of CoreMIDI and MidiShare drivers)
1223 - hand-crafted assembly optimization code can be disabled with
1224 './configure --disable-asm' (definitely not recommended)
1225 - fixed 'make dist' rule to include all necessary files
1226 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1227 (due to 'dist-bzip2' automake option)
1228
1229 * Gigasampler format engine:
1230 - support for the gig parameters for "release velocity response" curves
1231 - fine tuning of the EGADSR envelope
1232 - volume of release triggered samples now depends on note-on velocity,
1233 note length and gig parameter "release trigger decay" instead of
1234 note-off velocity.
1235 - revised voice stealing
1236 (fixes crash and endless loop caused by voice stealing)
1237 - don't reset scale tuning on instrument or audio output device change
1238 - handle key group conflicts right at the beginning of each fragment
1239 instead of when the respective voice is actually launched
1240 (fixes undefined behavior if stolen voices belonged to a key group -
1241 this case was followed by a "killed voice survived" error message)
1242 - fixed minor issue with null/silence samples
1243 (those stole voices even though they don't need a voice at all which
1244 resulted in "voice stealing didn't work out" messages)
1245 - don't reset volume, pan, pitch and MIDI controller values on
1246 instrument or audio output device change
1247
1248 * LSCP server:
1249 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1250 - fixed LSCP event "CHANNEL_INFO" notification
1251 (e.g. did not notify on volume changes or MIDI program change events)
1252
1253 * linuxsampler application:
1254 - added command line parameters --lscp-addr and --lscp-port to override
1255 default IP address and port of LSCP server
1256
1257 Version 0.3.1 (24 May 2005)
1258
1259 * initial release
