Sun Jul 17 18:41:21 2016 UTC (3 years, 7 months ago) by schoenebeck
File size: 67416 byte(s)
* All engines: Increased ramp speed of volume smoother and pan smoother
  (while slow rate of crossfade smoother is preserved) to allow quick
  volume and pan changes by instrument scripts for instance.
* Bumped version (2.0.0.svn21).

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
114 Version 2.0.0 (15 July 2015)
115

146 on the process's main thread
147 - fixed build error on newer MinGW
148 - support building with older jack versions
149 - support building with spaces in vst sdk path
150 - enabled automake 'subdir-objects' option and moved external
151 source references (vst, au, asio) from makefiles to cpp files,
152 in order to get rid of warnings from automake 1.14
153
154 * general changes:
155 - Refactoring: moved the independent code from
156 the Gigasampler format engine to base classes
157 - command line option '--profile' is currently disabled, since the
158 respective profiling code is currently broken
159 - Introduced support for optional environment variable
160 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
161 where the sampler shall look for instrument editor plugins
162 (patch by Luis Garrido, slightly modified).
163 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
164 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
165 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
166 note (in this implementation of the sampler its simply hard routed to
167 the 1st effect send of the sampler channel, no matter what the actual
168 effect type is)
169 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
170 note (in this implementation of the sampler its simply hard routed to
171 the 2nd effect send of the sampler channel, no matter what the actual
172 effect type is)
173 - implemented support for internal LADSPA effects
174 - raised limit of program change queue from 100 to 512
175 (as suggested by Alex Stone)
176 - implemented sine LFO, pulse LFO and saw LFO
177 - experimental support for per voice equalization
178 - added command line option --exec-after-init
179 - Introduced new C++ API method:
180 EngineChannel::InstrumentFileName(int index)
181 allowing to retrieve the whole list of files used for the loaded
182 instrument on an engine channel (a.k.a. part). Some GigaStudio
183 instruments for example are splitted over several files like
184 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
185 - Added new C++ API method Sampler::GetGlobalMaxVoices().
186 - Added new C++ API method Sampler::GetGlobalMaxStreams().
187 - Added new C++ API method Sampler::SetGlobalMaxVoices().
188 - Added new C++ API method Sampler::SetGlobalMaxStreams().
189 - Various "const" and "restrict" optimizations.
190 - all engines: add pan CC value to instrument pan parameter before
191 applying panning, instead of using two separate pan functions in
192 series (#182)
193 - added a lock guard class for exception safe mutex handling and
194 used it everywhere appropriate
195 - Immediately apply scale tuning changes to active voices.
196 - Exposed scale tuning to C++ API (along to the already existing standard
197 SysEx way).
198 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
199 and broken for ppc64. (Seq_cst loads and stores are actually not
200 used in LS, so the bug wasn't noticable.)
201 - lsatomic.h: added ARMv7 support
202 - Added support for multiple MIDI input ports per sampler channel (and
203 added various new C++ methods for this new feature / design change, old
204 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
205 as deprecated but are still there and should provide full behavior
206 backward compatibility).
207 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
208 unsafe and caused compilation error with clang 2.x).
209 - Bugfix: only process the latest MIDI program change event.
210 - Introducing the LSCP shell, which provides convenient control of the
211 sampler from the command line by providing LSCP aware features.
212 - VirtualMidiDevice: Added support for program change.
213 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
214 - VirtualMidiDevice: Added support for pitch bend.
215 - Aftertouch: extended API to explicitly handle channel pressure and
216 polyphonic key pressure events (so far polyphonic pressure was not
217 supported at all, and channel pressure was rerouted as CC128 but not
218 used so far).
219 - Added initial support for real-time instrument scripts. The script VM
220 code is shared by all sampler engine implemementations, however only the
221 gig file format currently provides support for storing instrument scripts
222 (as LinuxSampler extension to the original GigaStudio 4 format).
223
224 * Gigasampler format engine:
225 - implemented the "round robin keyboard" dimension
226 - fixed round robin and random dimensions for cases when number of
227 dimension zones is not a power of two
228 - made round robin use a counter for each region instead of each
229 key
230 - bugfix: pitch LFO controller "internal+aftertouch" was broken
231 - bugfix: filter keyboard tracking was broken
232 - filter performance fix (an unnecessary copy was made of the
233 filter parameters in each sub fragment)
234 - handle special case when pan parameter in gig file has max or
235 min value
236 - Exclusive Groups: don't ever stop voices of the same note,
237 doesn't sound naturally with a drumkit
238 - fixed EG1 modulation when attack or release is zero
239 - Fixed support for 'aftertouch' attenuation controller.
240 - Fixed crash that happened with velocity split sounds under certain
241 conditions (see also previous commit on libgig).
242 - fixed behaviour of filter LFO
243
244 * SFZ format engine:

252 - "key" opcode now sets pitch_keycenter too
253 - fixed error when unloading instrument with same sample used by
254 multiple regions
255 - added some opcode aliases, like loopmode for loop_mode, to be
256 more compatible
257 - added support for trigger=release and rt_decay

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

406 - bugfix: line numbers in error messages were wrong after "#include"
407 - added support for float and 32 bit sample files
408
409 * SoundFont format engine:
410 - Initial implementation (not usable yet)
411 - RT-safeness: avoid malloc in audio thread

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

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

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

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

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

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

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

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

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

770 - work-around for missing fnmatch function on Windows to make
771 instrument database compilable
772 - added instrument database support on Windows
773 works with both standalone mode and VST plugin.
774 the instruments DB file is located in
775 %USERPROFILE%\.linuxsampler\instruments.db which allows different
776 databases for each windows user
777 if no DB is present it automatically creates the .linuxsampler subdir
778 and then creates an empty DB
779 - fixed recursive import, which was broken on Windows
780
781 * Gigasampler format engine:
782 - fixed a memory leak that could happen when a channel was deleted
783 while notes were playing
784 - made it possible to load an instrument even if the audio thread
785 isn't running
786 - added partial support for the "Controller Triggered" MIDI rule,
787 enough for piano gigs with pedal noise samples
788 - minor fix: only mark FX sends as being modified if really the
789 respective FX send MIDI controller was used
790 - added support for GM global device volume SysEx message
791 (can be selected at compile time to either apply globally to the
792 whole sampler [default] or only to the sampler channels that are
793 connected to the respective MIDI input port the SysEx message arrived
794 on)
795 - bugfix: notes triggered at position 0 in the audio buffer were
796 sometimes wrongly killed in the same buffer, causing no sound to
797 be played
798 - added support for chromatic / drumkit mode Roland GS Sysex message
799 which is usally used to switch a part between chromatic sounds and
800 drumkit sounds (as opposed to their common default setting of MIDI
801 part 10 being a drumkit part and all other ones chromatic parts), in
802 LS however one can switch between the first 16 MIDI instrument maps
803 defined for the sampler
804 - made it possible to create multiple sample channels even if the
805 audio thread isn't running
806 - fixed crash when removing channel with active voices (#116)
807 - bugfix: on sample reference changes (instrument editor), only
808 un-cache the respective sample if it's really not used by any
809 sampler engine anymore
810 - re-cache samples in case they were changed by an instrument editor,
811 e.g. when a sample was added while playing (#82)
812 - fixed hanging notes which occured when note-off event had the exact
813 same time stamp as the voice's note-on event and occured both in the
814 same audio fragment cycle (fixes bug #112)
815 - added support for the "fine tune" and "pitch bend range"
816 instrument-level gig parameters
817 - fixed minor artifacts in pitch bend handling
818 - added support for GS Reset SysEx message
819 - allow gig files to use unlimited downward pitch shifting
820 - added a limit check for upward pitch shifting
821 - bugfix: sometimes, when playing a note twice fast, the second
822 note was silent
823 - fixed crash happening when a pitch bend event arrived at the
824 same time a new instrument was loading
825
826 * LSCP server:
827 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
828 react on MIDI data arriving on certain sampler channels (so far only
829 Note-On and Note-Off events are sent via this LSCP event)
830 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
831 react on MIDI data arriving on certain MIDI input devices (so far only
832 Note-On and Note-Off events are sent via this LSCP event)
833 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
834 SET DB_INSTRUMENT FILE_PATH
835 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
836 frontends to send MIDI messages to specific sampler channel
837 - added two additional fields to GET FILE INSTRUMENT INFO command -
838 KEY_BINDINGS and KEYSWITCH_BINDINGS
839 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
840 was incorrect
841 - Optimized the retrieval of the MIDI instrument mappings
842 - added new LSCP command "SET VOICES" to globally alter the maximum
843 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
844 be triggered respectively
845 - added new LSCP command "SET STREAMS" to globally alter the maximum
846 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
847 which will be triggered respectively
848 - bugfix: retry if "select" returns EINTR (this fixes a crash when
849 a gigedit file dialog is opened)
850 - close all connections when LSCPServer is deleted
851 - hard close of all sockets on exit
852 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
853 driver
854
855 * Bug fixes:
856 - fixed a crash which occurs when removing a sampler channel waiting
857 to start instrument loading after another channel
858 - fixed a crash which occurs when removing a sampler channel with
859 instrument loading in progress (bug #113)
860 - fixed termination caused by uncaught exception when adding MIDI
861 instrument with PERSISTENT load mode
862 - fixed possible iterator invalidations when resetting the sampler
863 - fixed memory leaks when issuing the following LSCP commands:
864 GET AUDIO_OUTPUT_DRIVER INFO
865 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
866 GET MIDI_INPUT_DRIVER INFO
867 GET MIDI_INPUT_DRIVER_PARAMETER INFO
868 - fixed possible compilation error when sqlite is not present
869 - fixed orphaned pointers when setting maximum voices limit (bug #118)
870 - fixed crash when changing the audio output device of a sampler
871 channel with loaded instrument and start playing notes
872 - fixed endless loop in Engine::SuspendAll() (bug #120)
873 - fixed a low-level atomic load function that was broken on 64-bit
874 PowerPC, which probably could cause crashes on that platform
875 - fixed a memory management error which could cause a crash when a
876 plugin was unloaded
877 - bugfix: two private structs had the same name, which could cause
878 problems if the linker chose the wrong constructor
879 - fixed low-level ConditionServer usage bug that caused lockups on
880 Windows
881
882
883 Version 0.5.1 (6 December 2007)
884
885 * packaging changes:
886 - added autoconf checks for pthread library
887 - added autoconf check for pthread bug found on certain NPTL-enabled
888 glibc versions (see Gentoo bug report #194076)
889 - added autoconf checks for MS Windows
890
891 * general changes:
892 - bugfix: the thread used by an editor plugin didn't die when the
893 editor closed
894 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
895 out all the space. operator--() did not apply size_mask after
896 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
897 order to avoid problems with the _NonVolatileReader functions.
898 - bugfix: Stream.h: added a missing divide by BytesPerSample in
899 GetWriteSpace(). Since this function is currently only used in
900 the stream's qsort() compare function, it didn't trigger any
901 bugs.
902 - Resampler.h, Synthesizer.h: cubic interpolation now works in
903 24bit mode too. Faster method to read 24bit words on little
904 endian machines (x86): replaced 3 byte reads + shifts with a 1
905 unaligned 32bit read and shift
906 - experimental support for MS Windows (MIDI input via MME, AUDIO
907 output via ASIO)
908 - made handling of SIGINT signal (Ctrl-C) a bit more robust
909 - support for monitoring the total number of active disk streams
910 (new LSCP commands: GET TOTAL_STREAM_COUNT,
911 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
912
913 * AUDIO driver:
914 - added Windows ASIO low latency audio driver
915
916 * MIDI driver:
917 - added MME Windows MIDI driver
918
919 * LSCP server:
920 - added support for Windows style path / filenames, however with
921 forward slash path separators instead of backslash
922 (i.e. "C:/foo/bar.gig")
923 - allow naughty liblscp to send non-string device parameters within
924 apostrophes as well
925 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
926 "LIST FILE INSTRUMENTS <file>" and
927 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
928 about an arbitrary instrument file on the system where the sampler is
929 running on
930
931 Version 0.5.0 (15 October 2007)
932
933 * packaging changes:
934 - config.h is not going to be installed along with liblinuxsampler's
935 API header files anymore
936 - only the API relevant header (and source) files will be exported to
937 the Doxygen API documentation (explicitly listed in Doxyfile.in)
938 - added completely new XCode project files for Mac OSX which is now
939 capable to execute our autoconf environment, thus no need anymore
940 to maintain the compile time configuration file (osx/version.h) for
941 OSX manually (patch by Toshi Nagata)
942 - fixed buggy boolean --enable-foo / --disable-foo configure script
943 parameters
944 - global.h now only covers global definitions that are needed for the
945 C++ API header files, all implementation internal global definitions
946 are now in global_private.h
947 - atomic.h is not exposed to the C++ API anymore
948 - no need to include config.h anymore for using LS's API header files
949 - fixed warnings in API doc generation
950
951 * general changes:
952 - replaced the old, confusing MIDI program change mechanism by a
953 flexible MIDI instrument mapper which allows to map arbitrary
954 (MIDI bank, MIDI program) pairs with arbitrary
955 (engine type, instrument file, file index) triplets which will be
956 loaded on the respective channel when such MIDI program change
957 messages arrive, beside that, each entry allows to define a life-time
958 strategy for the instrument, so the user can define whether the
959 instrument should i.e. be permanently loaded (to be able to switch
960 quickly among sounds) or i.e. loaded just on demand when the
961 respective program change arrives (to safe RAM space), as well as a
962 global volume factor for each entry, so the user can adjust the volume
963 dynamic of his mapped instrument collection without having to modify
964 the instrument files, also one can manage arbitrary amount of such
965 MIDI instrument maps and assign each sampler channel individually
966 a certain map, so that i.e. separation of normal instruments and
967 drumkits is possible
968 - new notification events for tracking changes to audio/MIDI devices,
969 MIDI instrument maps, MIDI instruments, FX sends, global volume.
970 - sampler was limited to load max. 200 instruments in the background
971 due to a constant size RingBuffer FIFO which is now replaced by a
972 dynamic (unlimited) size std::list FIFO
973 - added FX sends, these allow to route audio signals to arbitrary audio
974 output channels for being processed by external effect processors
975 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
976 controllers
977 - global (sampler wide) volume can now be controlled at runtime
978 - Implemented new, improved notification system
979 - fixed compilation errors regarding OSX
980 (patch by Toshi Nagata)
981 - implemented instruments database
982 - added support for escape sequences to the instruments database
983 - added highly experimental support for on-the-fly instrument editing
984 within the sampler's process (by using instrument editor plugins),
985 you'll notice the new "Registered instrument editors:" message on
986 startup, added a new LSCP command:
987 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
988 to spawn a matching instrument editor for the instrument on the
989 given sampler channel, the plugin path can be overridden at compile
990 time with ./configure --enable-plugin-dir=/some/dir
991 - added experimental code for synchronizing instrument editors hosted
992 in the sampler's process to safely edit instruments while playing
993 without a crash (hopefully) by either suspending single regions
994 wherever possible or if unavoidable whole engine(s)
995 - fixed several issues in fundamental "Thread" class: set scheduling
996 policy and priority on thread level, set a minimum stack size for
997 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
998 threads simply inherited properties of starting thread instead of
999 setting their own policy and priority
1000 - minor fix in our automatic stack trace mechanism on crashes, the
1001 main process did not wait for the stack trace process to finish
1002 its output
1003 - fixed some minor memory leaks
1004 - reenabled assembly features support, at the moment only for
1005 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1006 - minor assembly fix in x86 features detection (don't use the PIC
1007 register, to avoid relocations in the text segment at runtime)
1008 - POSIX callback functions of Thread.h are hidden
1009
1010 * MIDI driver:
1011 - dispatch bank select (MSB and LSB) messages
1012
1013 * audio driver:
1014 - the ALSA audio output driver parameters now reflect the correct
1015 parameter value ranges for the respective selected sound card
1016 (patch by Till Wimmer, a bit fixed and extended)
1017
1018 * Gigasampler format engine:
1019 - if a filter is used and EG2 finishes before EG1, let the voice
1020 die when EG2 has finished (this fixes a problem with clicks and
1021 voice starvation for some gigs)
1022 - playback is no longer disabled during instrument loading
1023 - all notes playing on a channel that changes its instrument keep
1024 playing with the old instrument until they get a note off
1025 command
1026 - EG fix: a release value of zero could cause noises or crash
1027 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1028 - EG fine tuning: when attack is zero the EG starts at a level
1029 above max sustain level, which means that there is a decay phase
1030 even if sustain is 100%
1031 - more EG fixes: the level could sometimes go below zero and cause
1032 noises or crashes
1033 - minor fix of EGDecay (patch by Toshi Nagata)
1034 - fixed compiler error when --enable-override-filter-type was
1035 supplied to the configure script (fixes #46)
1036 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1037 instead of a fix value
1038 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1039 127 (solo mode) only kill voices if the respective mode really
1040 changed
1041
1042 * LSCP server:
1043 - fixed compile time error for old Bison versions
1044 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1045 - parser now supports extended ASCII character set
1046 (up to ASCII code 255, i.e. includes now umlauts and accents)
1047 - filename arguments in LSCP commands now allow to use escape
1048 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1049 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1050 code value like \xf2) (fixes bug #24)
1051 - the following LSCP commands now also support escape sequences for at
1052 least one of their text-based parameters (i.e. name, description):
1053 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1054 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1055 "SET DB_INSTRUMENT_DIRECTORY NAME",
1056 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1057 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1058 "FIND DB_INSTRUMENT_DIRECTORIES"
1059 - returns verbose syntax errors (line and column where syntax error
1060 occured, the unexpected character and the actually expected, possible
1061 character(s), the latter only if less than 5 possibilities)
1062 - made sure that LSCP syntax is not affected by gigedit locale
1063 settings
1064 - bugfix regarding strings parameter lists: all comma separated lists
1065 of strings were treated as being one string containing commas
1066 (fixes #57)
1067
1068 * Bug fixes:
1069 - fixed crash occurring on certain LSCP scripts (Bug 39)
1070 - another thread safety fix for lscp "load engine" and "set
1071 channel audio output device"
1072 - fixed a crash which occurs when reassigning the same engine
1073 on a sampler channel with connected MIDI device
1074 - fixed a crash which occurs when changing the number of ports of a MIDI
1075 device connected to a sampler channel to number less then or equal
1076 to the index of the port to which the sampler channel is connected.
1077 - The previous bindings were not been disconnected when altering
1078 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1079 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1080 - The active stream/voice count statistic was incorrect.
1081 - notification events were not been sent for some sampler
1082 channel changes
1083 - added default min and max values to restrict the number of allowed
1084 audio output channels and MIDI input ports
1085 - the connection to the PCM interface is now closed when destroying
1086 an audio output device
1087 - files with slash in their path or filename could not be loaded
1088
1089 * test cases:
1090 - updated and fixed (haven't been touched in a while)
1091
1092 Version 0.4.0 (24 November 2006)
1093
1094 * packaging changes:
1095 - changed deprecated copyright attribute to license; added ldconfig
1096 to post-(un)install steps; added devel package for liblinuxsampler;
1097 to linuxsampler.spec (RPM)
1098 - install necessary development header files for allowing 3rd party
1099 applications to link against liblinuxsampler
1100 - liblinuxsampler's API documentation can be generated with 'make docs'
1101 (Doxygen required)
1102 - added benchmark to automatically detect the best triangle LFO
1103 implementation (currently either an integer math solution or a
1104 di-harmonic approximation), automatic detection can be overriden
1105 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1106 configure script argument though (mandatory for cross-compilation)
1107 - do not automatically pick optimized gcc flags if the user already
1108 provided some on his own (as CXXFLAGS)
1109 - added compile time option to disable processing of All-Notes-Off MIDI
1110 messages
1111 - added compile time options to allow disabling the various audio and
1112 MIDI drivers
1113 - fixed automatic GCC CPU switch detection on PPC
1114 (patch by Ebrahim Mayat)
1115
1116 * Gigasampler format engine:
1117 - extensive synthesis optimization
1118 (reimplementation of EGs and LFO(s), removed synthesis parameter
1119 prerendering and the synthesis parameter matrix in general, splitting
1120 each audio fragment into subfragments now where each subfragment uses
1121 constant pitch and filter coefficients. The volume coefficient is
1122 linearly interpolated inside a subfragment, unless
1123 --disable-interpolate-volume is set.)
1124 - fine tuning of the EG modulation parameters
1125 - improved filter cutoff calculation by adding support for the
1126 following gig parameters: Cutoff freq (used when no cutoff
1127 controller is defined), Control invert, Minimum cutoff, Velocity
1128 curve and Velocity range. The keyboard tracking now scales
1129 cutoff frequency instead of resonance.
1130 - added support for gig parameter Resonance.
1131 - fixed bug in sysex handling (patch by Juan Linietsky)
1132 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1133 which can be overridden with --enable-global-attenuation
1134 - EG fixes: made the length of "attack hold" stage more
1135 accurate. Release stage can now start before attack stage
1136 ends. Cancel release didn't work when sustain was zero. Attack
1137 time now has a minimal value to prevent clicks.
1138 - fixed pitch changes larger than one octave
1139 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1140 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1141 all modes can be altered via standard GM messages, that is CC5 for
1142 altering portamento time, CC65 for enabling / disabling portamento
1143 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1144 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1145 parameter) and crossfade
1146 - added support for the "attenuation controller threshold" gig
1147 parameter
1148 - added smoothing of volume changes caused by control change
1149 messages
1150 - sample loop parameters are now taken from the DimensionRegion
1151 instead of the wave chunk
1152 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1153 not equal to a power of two
1154 - reimplementation of the filter algorithm. The new filter is more
1155 accurate and supports all gig filter types, including bandreject
1156 and lowpass turbo.
1157 - real support for 24 bit samples - samples are not truncated to
1158 16 bits anymore
1159 - support for aftertouch (channel pressure, not polyphonic
1160 aftertouch)
1161 - LFO1 behaviour fixed (dampening from max volume instead of
1162 amplifying from 0)
1163
1164 * LSCP server:
1165 - fixed application exit on broken pipe error (fixes bug #20)
1166 - fixed the notification messages delay due to lack of
1167 network activity (fixes bug #26)
1168 - fixed parser bug which occured on space(s) within device parameters
1169 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1170
1171 * audio driver:
1172 - added aRts audio output driver (by no means RT safe)
1173
1174 * MIDI driver:
1175 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1176 messages several times instead of once
1177 - API extension for MIDI drivers which already supply exact time stamps
1178 for events (i.e. for offline rendering based MIDI drivers)
1179 - added checks for bad MIDI data
1180
1181 * linuxsampler application:
1182 - show available sampler engine types on startup
1183
1184 * general changes:
1185 - support for muting sampler channels and solo mode of the same, two new
1186 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1187 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1188 introduced for this, the behavior is the same like on a mixer console
1189 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1190 --enable-process-muted-channels which can be used to enable the
1191 processing of muted channels.
1192 - support for sostenuto pedal
1193 - support for monitoring the total number of active voices
1194 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1195 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1196 - fixed some memory management errors
1197 - fixed some concurrency problems that could lead to crashes when
1198 LSCP commands were executed
1199 - fixed crash when instrument loading failed previously on the same
1200 sampler channel (fixes bug #36)
1201
1202 Version 0.3.3 (15 July 2005)
1203
1204 * packaging changes:
1205 - fixed compilation with gcc 4.0
1206
1207 * Gigasampler format engine:
1208 - LFO preprocessing was performed even though the respective LFO was
1209 disabled by the instrument patch (minor efficiency fix)
1210 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1211 for volume ramp downs in the same fragment (needed for current voice
1212 stealing implementation) then simply inform the user with a warning
1213 about possible click sounds and reduce the volume ramp down
1214 appropriately instead of cancelling the audio device connection
1215
1216 Version 0.3.2 (24 June 2005)
1217
1218 * packaging changes:
1219 - updated autotools build files to compile on OS X
1220 (conditional compilation of CoreMIDI and MidiShare drivers)
1221 - hand-crafted assembly optimization code can be disabled with
1222 './configure --disable-asm' (definitely not recommended)
1223 - fixed 'make dist' rule to include all necessary files
1224 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1225 (due to 'dist-bzip2' automake option)
1226
1227 * Gigasampler format engine:
1228 - support for the gig parameters for "release velocity response" curves
1229 - fine tuning of the EGADSR envelope
1230 - volume of release triggered samples now depends on note-on velocity,
1231 note length and gig parameter "release trigger decay" instead of
1232 note-off velocity.
1233 - revised voice stealing
1234 (fixes crash and endless loop caused by voice stealing)
1235 - don't reset scale tuning on instrument or audio output device change
1236 - handle key group conflicts right at the beginning of each fragment
1237 instead of when the respective voice is actually launched
1238 (fixes undefined behavior if stolen voices belonged to a key group -
1239 this case was followed by a "killed voice survived" error message)
1240 - fixed minor issue with null/silence samples
1241 (those stole voices even though they don't need a voice at all which
1242 resulted in "voice stealing didn't work out" messages)
1243 - don't reset volume, pan, pitch and MIDI controller values on
1244 instrument or audio output device change
1245
1246 * LSCP server:
1247 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1248 - fixed LSCP event "CHANNEL_INFO" notification
1249 (e.g. did not notify on volume changes or MIDI program change events)
1250
1251 * linuxsampler application:
1252 - added command line parameters --lscp-addr and --lscp-port to override
1253 default IP address and port of LSCP server
1254
1255 Version 0.3.1 (24 May 2005)
1256
1257 * initial release
