Thu Jul 21 16:22:55 2016 UTC (7 years, 8 months ago) by schoenebeck
File size: 67633 byte(s)
* NKSP: Implemented built-in script function "min()".
* NKSP: Implemented built-in script function "max()".
* Bumped version (2.0.0.svn23).

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 - Implemented built-in script function "min()".
116 - Implemented built-in script function "max()".

156 in order to get rid of warnings from automake 1.14
157
158 * general changes:
159 - Refactoring: moved the independent code from
160 the Gigasampler format engine to base classes
161 - command line option '--profile' is currently disabled, since the
162 respective profiling code is currently broken
163 - Introduced support for optional environment variable
164 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
165 where the sampler shall look for instrument editor plugins
166 (patch by Luis Garrido, slightly modified).
167 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
168 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
169 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
170 note (in this implementation of the sampler its simply hard routed to
171 the 1st effect send of the sampler channel, no matter what the actual
172 effect type is)
173 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
174 note (in this implementation of the sampler its simply hard routed to
175 the 2nd effect send of the sampler channel, no matter what the actual
176 effect type is)
177 - implemented support for internal LADSPA effects
178 - raised limit of program change queue from 100 to 512
179 (as suggested by Alex Stone)
180 - implemented sine LFO, pulse LFO and saw LFO
181 - experimental support for per voice equalization
182 - added command line option --exec-after-init
183 - Introduced new C++ API method:
184 EngineChannel::InstrumentFileName(int index)
185 allowing to retrieve the whole list of files used for the loaded
186 instrument on an engine channel (a.k.a. part). Some GigaStudio
187 instruments for example are splitted over several files like
188 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
189 - Added new C++ API method Sampler::GetGlobalMaxVoices().
190 - Added new C++ API method Sampler::GetGlobalMaxStreams().
191 - Added new C++ API method Sampler::SetGlobalMaxVoices().
192 - Added new C++ API method Sampler::SetGlobalMaxStreams().
193 - Various "const" and "restrict" optimizations.
194 - all engines: add pan CC value to instrument pan parameter before
195 applying panning, instead of using two separate pan functions in
196 series (#182)
197 - added a lock guard class for exception safe mutex handling and
198 used it everywhere appropriate
199 - Immediately apply scale tuning changes to active voices.
200 - Exposed scale tuning to C++ API (along to the already existing standard
201 SysEx way).
202 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
203 and broken for ppc64. (Seq_cst loads and stores are actually not
204 used in LS, so the bug wasn't noticable.)
205 - lsatomic.h: added ARMv7 support
206 - Added support for multiple MIDI input ports per sampler channel (and
207 added various new C++ methods for this new feature / design change, old
208 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
209 as deprecated but are still there and should provide full behavior
210 backward compatibility).
211 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
212 unsafe and caused compilation error with clang 2.x).
213 - Bugfix: only process the latest MIDI program change event.
214 - Introducing the LSCP shell, which provides convenient control of the
215 sampler from the command line by providing LSCP aware features.
216 - VirtualMidiDevice: Added support for program change.
217 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
218 - VirtualMidiDevice: Added support for pitch bend.
219 - Aftertouch: extended API to explicitly handle channel pressure and
220 polyphonic key pressure events (so far polyphonic pressure was not
221 supported at all, and channel pressure was rerouted as CC128 but not
222 used so far).
223 - Added initial support for real-time instrument scripts. The script VM
224 code is shared by all sampler engine implemementations, however only the
225 gig file format currently provides support for storing instrument scripts
226 (as LinuxSampler extension to the original GigaStudio 4 format).
227
228 * Gigasampler format engine:
229 - implemented the "round robin keyboard" dimension
230 - fixed round robin and random dimensions for cases when number of
231 dimension zones is not a power of two
232 - made round robin use a counter for each region instead of each
233 key
234 - bugfix: pitch LFO controller "internal+aftertouch" was broken
235 - bugfix: filter keyboard tracking was broken
236 - filter performance fix (an unnecessary copy was made of the
237 filter parameters in each sub fragment)
238 - handle special case when pan parameter in gig file has max or
239 min value
240 - Exclusive Groups: don't ever stop voices of the same note,
241 doesn't sound naturally with a drumkit
242 - fixed EG1 modulation when attack or release is zero
243 - Fixed support for 'aftertouch' attenuation controller.
244 - Fixed crash that happened with velocity split sounds under certain
245 conditions (see also previous commit on libgig).
246 - fixed behaviour of filter LFO
247
248 * SFZ format engine:
249 - Initial implementation (not usable yet)

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

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

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

423 - AU bugfix: failed to destroy its audio/MIDI devices
424 - Listen to all interfaces on Mac OS X (INADDR_ANY)
425 - VST bugfix: If the host called resume() before and after
426 changing sample rate or block size, the number of channels was
427 incorrectly set to two. This caused silence in Cubase 5.
428 - save engine type (gig, sfz or sf2) in plugin state
429 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
430 64 bit Windows

440 loaded a second time (this time it's for Linux and Mac, previous
441 similar fix was for Windows)
442 - thread safety fixes for the instrument loading thread

444 - VST: try to open Fantasia automatically on Linux and Mac too (on
445 Linux, the Fantasia jar should be placed in <prefix>/share/java)
446 - VST: fixed crashes on Linux Ardour and EnergyXT
447 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
448 port and audio channel routing for DSSI plugins are now visible.
449 - LV2: use urid and atom extensions instead of deprecated uri-map
450 and event
451 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

458
459 * Instrument editor interface:
460 - Changed instrument editor plugin interface, providing additional
461 informations like the EngineChannel for which the instrument editor was
462 spawned for. This allows the instrument editors to interact more actively
463 with the sampler.
464
465 * MIDI driver:
466 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
467 the ALSA sequencer client name

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

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

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

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

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

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

774 - work-around for missing fnmatch function on Windows to make
775 instrument database compilable
776 - added instrument database support on Windows
777 works with both standalone mode and VST plugin.
778 the instruments DB file is located in
779 %USERPROFILE%\.linuxsampler\instruments.db which allows different
780 databases for each windows user
781 if no DB is present it automatically creates the .linuxsampler subdir
782 and then creates an empty DB
783 - fixed recursive import, which was broken on Windows
784
785 * Gigasampler format engine:
786 - fixed a memory leak that could happen when a channel was deleted
787 while notes were playing
788 - made it possible to load an instrument even if the audio thread
789 isn't running
790 - added partial support for the "Controller Triggered" MIDI rule,
791 enough for piano gigs with pedal noise samples
792 - minor fix: only mark FX sends as being modified if really the
793 respective FX send MIDI controller was used
794 - added support for GM global device volume SysEx message
795 (can be selected at compile time to either apply globally to the
796 whole sampler [default] or only to the sampler channels that are
797 connected to the respective MIDI input port the SysEx message arrived
798 on)
799 - bugfix: notes triggered at position 0 in the audio buffer were
800 sometimes wrongly killed in the same buffer, causing no sound to
801 be played
802 - added support for chromatic / drumkit mode Roland GS Sysex message
803 which is usally used to switch a part between chromatic sounds and
804 drumkit sounds (as opposed to their common default setting of MIDI
805 part 10 being a drumkit part and all other ones chromatic parts), in
806 LS however one can switch between the first 16 MIDI instrument maps
807 defined for the sampler
808 - made it possible to create multiple sample channels even if the
809 audio thread isn't running
810 - fixed crash when removing channel with active voices (#116)
811 - bugfix: on sample reference changes (instrument editor), only
812 un-cache the respective sample if it's really not used by any
813 sampler engine anymore
814 - re-cache samples in case they were changed by an instrument editor,
815 e.g. when a sample was added while playing (#82)
816 - fixed hanging notes which occured when note-off event had the exact
817 same time stamp as the voice's note-on event and occured both in the
818 same audio fragment cycle (fixes bug #112)
819 - added support for the "fine tune" and "pitch bend range"
820 instrument-level gig parameters
821 - fixed minor artifacts in pitch bend handling
822 - added support for GS Reset SysEx message
823 - allow gig files to use unlimited downward pitch shifting
824 - added a limit check for upward pitch shifting
825 - bugfix: sometimes, when playing a note twice fast, the second
826 note was silent
827 - fixed crash happening when a pitch bend event arrived at the
828 same time a new instrument was loading
829
830 * LSCP server:
831 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
832 react on MIDI data arriving on certain sampler channels (so far only
833 Note-On and Note-Off events are sent via this LSCP event)
834 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
835 react on MIDI data arriving on certain MIDI input devices (so far only
836 Note-On and Note-Off events are sent via this LSCP event)
837 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
838 SET DB_INSTRUMENT FILE_PATH
839 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
840 frontends to send MIDI messages to specific sampler channel
841 - added two additional fields to GET FILE INSTRUMENT INFO command -
842 KEY_BINDINGS and KEYSWITCH_BINDINGS
843 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
844 was incorrect
845 - Optimized the retrieval of the MIDI instrument mappings
846 - added new LSCP command "SET VOICES" to globally alter the maximum
847 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
848 be triggered respectively
849 - added new LSCP command "SET STREAMS" to globally alter the maximum
850 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
851 which will be triggered respectively
852 - bugfix: retry if "select" returns EINTR (this fixes a crash when
853 a gigedit file dialog is opened)
854 - close all connections when LSCPServer is deleted
855 - hard close of all sockets on exit
856 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
857 driver
858
859 * Bug fixes:
860 - fixed a crash which occurs when removing a sampler channel waiting
861 to start instrument loading after another channel
862 - fixed a crash which occurs when removing a sampler channel with
863 instrument loading in progress (bug #113)
864 - fixed termination caused by uncaught exception when adding MIDI
865 instrument with PERSISTENT load mode
866 - fixed possible iterator invalidations when resetting the sampler
867 - fixed memory leaks when issuing the following LSCP commands:
868 GET AUDIO_OUTPUT_DRIVER INFO
869 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
870 GET MIDI_INPUT_DRIVER INFO
871 GET MIDI_INPUT_DRIVER_PARAMETER INFO
872 - fixed possible compilation error when sqlite is not present
873 - fixed orphaned pointers when setting maximum voices limit (bug #118)
874 - fixed crash when changing the audio output device of a sampler
875 channel with loaded instrument and start playing notes
876 - fixed endless loop in Engine::SuspendAll() (bug #120)
877 - fixed a low-level atomic load function that was broken on 64-bit
878 PowerPC, which probably could cause crashes on that platform
879 - fixed a memory management error which could cause a crash when a
880 plugin was unloaded
881 - bugfix: two private structs had the same name, which could cause
882 problems if the linker chose the wrong constructor
883 - fixed low-level ConditionServer usage bug that caused lockups on
884 Windows
885
886
887 Version 0.5.1 (6 December 2007)
888
889 * packaging changes:
890 - added autoconf checks for pthread library
891 - added autoconf check for pthread bug found on certain NPTL-enabled
892 glibc versions (see Gentoo bug report #194076)
893 - added autoconf checks for MS Windows
894
895 * general changes:
896 - bugfix: the thread used by an editor plugin didn't die when the
897 editor closed
898 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
899 out all the space. operator--() did not apply size_mask after
900 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
901 order to avoid problems with the _NonVolatileReader functions.
902 - bugfix: Stream.h: added a missing divide by BytesPerSample in
903 GetWriteSpace(). Since this function is currently only used in
904 the stream's qsort() compare function, it didn't trigger any
905 bugs.
906 - Resampler.h, Synthesizer.h: cubic interpolation now works in
907 24bit mode too. Faster method to read 24bit words on little
908 endian machines (x86): replaced 3 byte reads + shifts with a 1
909 unaligned 32bit read and shift
910 - experimental support for MS Windows (MIDI input via MME, AUDIO
911 output via ASIO)
912 - made handling of SIGINT signal (Ctrl-C) a bit more robust
913 - support for monitoring the total number of active disk streams
914 (new LSCP commands: GET TOTAL_STREAM_COUNT,
915 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
916
917 * AUDIO driver:
918 - added Windows ASIO low latency audio driver
919
920 * MIDI driver:
921 - added MME Windows MIDI driver
922
923 * LSCP server:
924 - added support for Windows style path / filenames, however with
925 forward slash path separators instead of backslash
926 (i.e. "C:/foo/bar.gig")
927 - allow naughty liblscp to send non-string device parameters within
928 apostrophes as well
929 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
930 "LIST FILE INSTRUMENTS <file>" and
931 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
932 about an arbitrary instrument file on the system where the sampler is
933 running on
934
935 Version 0.5.0 (15 October 2007)
936
937 * packaging changes:
938 - config.h is not going to be installed along with liblinuxsampler's
939 API header files anymore
940 - only the API relevant header (and source) files will be exported to
941 the Doxygen API documentation (explicitly listed in Doxyfile.in)
942 - added completely new XCode project files for Mac OSX which is now
943 capable to execute our autoconf environment, thus no need anymore
944 to maintain the compile time configuration file (osx/version.h) for
945 OSX manually (patch by Toshi Nagata)
946 - fixed buggy boolean --enable-foo / --disable-foo configure script
947 parameters
948 - global.h now only covers global definitions that are needed for the
949 C++ API header files, all implementation internal global definitions
950 are now in global_private.h
951 - atomic.h is not exposed to the C++ API anymore
952 - no need to include config.h anymore for using LS's API header files
953 - fixed warnings in API doc generation
954
955 * general changes:
956 - replaced the old, confusing MIDI program change mechanism by a
957 flexible MIDI instrument mapper which allows to map arbitrary
958 (MIDI bank, MIDI program) pairs with arbitrary
959 (engine type, instrument file, file index) triplets which will be
960 loaded on the respective channel when such MIDI program change
961 messages arrive, beside that, each entry allows to define a life-time
962 strategy for the instrument, so the user can define whether the
963 instrument should i.e. be permanently loaded (to be able to switch
964 quickly among sounds) or i.e. loaded just on demand when the
965 respective program change arrives (to safe RAM space), as well as a
966 global volume factor for each entry, so the user can adjust the volume
967 dynamic of his mapped instrument collection without having to modify
968 the instrument files, also one can manage arbitrary amount of such
969 MIDI instrument maps and assign each sampler channel individually
970 a certain map, so that i.e. separation of normal instruments and
971 drumkits is possible
972 - new notification events for tracking changes to audio/MIDI devices,
973 MIDI instrument maps, MIDI instruments, FX sends, global volume.
974 - sampler was limited to load max. 200 instruments in the background
975 due to a constant size RingBuffer FIFO which is now replaced by a
976 dynamic (unlimited) size std::list FIFO
977 - added FX sends, these allow to route audio signals to arbitrary audio
978 output channels for being processed by external effect processors
979 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
980 controllers
981 - global (sampler wide) volume can now be controlled at runtime
982 - Implemented new, improved notification system
983 - fixed compilation errors regarding OSX
984 (patch by Toshi Nagata)
985 - implemented instruments database
986 - added support for escape sequences to the instruments database
987 - added highly experimental support for on-the-fly instrument editing
988 within the sampler's process (by using instrument editor plugins),
989 you'll notice the new "Registered instrument editors:" message on
990 startup, added a new LSCP command:
991 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
992 to spawn a matching instrument editor for the instrument on the
993 given sampler channel, the plugin path can be overridden at compile
994 time with ./configure --enable-plugin-dir=/some/dir
995 - added experimental code for synchronizing instrument editors hosted
996 in the sampler's process to safely edit instruments while playing
997 without a crash (hopefully) by either suspending single regions
998 wherever possible or if unavoidable whole engine(s)
999 - fixed several issues in fundamental "Thread" class: set scheduling
1000 policy and priority on thread level, set a minimum stack size for
1001 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1002 threads simply inherited properties of starting thread instead of
1003 setting their own policy and priority
1004 - minor fix in our automatic stack trace mechanism on crashes, the
1005 main process did not wait for the stack trace process to finish
1006 its output
1007 - fixed some minor memory leaks
1008 - reenabled assembly features support, at the moment only for
1009 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1010 - minor assembly fix in x86 features detection (don't use the PIC
1011 register, to avoid relocations in the text segment at runtime)
1012 - POSIX callback functions of Thread.h are hidden
1013
1014 * MIDI driver:
1015 - dispatch bank select (MSB and LSB) messages
1016
1017 * audio driver:
1018 - the ALSA audio output driver parameters now reflect the correct
1019 parameter value ranges for the respective selected sound card
1020 (patch by Till Wimmer, a bit fixed and extended)
1021
1022 * Gigasampler format engine:
1023 - if a filter is used and EG2 finishes before EG1, let the voice
1024 die when EG2 has finished (this fixes a problem with clicks and
1025 voice starvation for some gigs)
1026 - playback is no longer disabled during instrument loading
1027 - all notes playing on a channel that changes its instrument keep
1028 playing with the old instrument until they get a note off
1029 command
1030 - EG fix: a release value of zero could cause noises or crash
1031 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1032 - EG fine tuning: when attack is zero the EG starts at a level
1033 above max sustain level, which means that there is a decay phase
1034 even if sustain is 100%
1035 - more EG fixes: the level could sometimes go below zero and cause
1036 noises or crashes
1037 - minor fix of EGDecay (patch by Toshi Nagata)
1038 - fixed compiler error when --enable-override-filter-type was
1039 supplied to the configure script (fixes #46)
1040 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1041 instead of a fix value
1042 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1043 127 (solo mode) only kill voices if the respective mode really
1044 changed
1045
1046 * LSCP server:
1047 - fixed compile time error for old Bison versions
1048 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1049 - parser now supports extended ASCII character set
1050 (up to ASCII code 255, i.e. includes now umlauts and accents)
1051 - filename arguments in LSCP commands now allow to use escape
1052 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1053 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1054 code value like \xf2) (fixes bug #24)
1055 - the following LSCP commands now also support escape sequences for at
1056 least one of their text-based parameters (i.e. name, description):
1057 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1058 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1059 "SET DB_INSTRUMENT_DIRECTORY NAME",
1060 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1061 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1062 "FIND DB_INSTRUMENT_DIRECTORIES"
1063 - returns verbose syntax errors (line and column where syntax error
1064 occured, the unexpected character and the actually expected, possible
1065 character(s), the latter only if less than 5 possibilities)
1066 - made sure that LSCP syntax is not affected by gigedit locale
1067 settings
1068 - bugfix regarding strings parameter lists: all comma separated lists
1069 of strings were treated as being one string containing commas
1070 (fixes #57)
1071
1072 * Bug fixes:
1073 - fixed crash occurring on certain LSCP scripts (Bug 39)
1074 - another thread safety fix for lscp "load engine" and "set
1075 channel audio output device"
1076 - fixed a crash which occurs when reassigning the same engine
1077 on a sampler channel with connected MIDI device
1078 - fixed a crash which occurs when changing the number of ports of a MIDI
1079 device connected to a sampler channel to number less then or equal
1080 to the index of the port to which the sampler channel is connected.
1081 - The previous bindings were not been disconnected when altering
1082 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1083 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1084 - The active stream/voice count statistic was incorrect.
1085 - notification events were not been sent for some sampler
1086 channel changes
1087 - added default min and max values to restrict the number of allowed
1088 audio output channels and MIDI input ports
1089 - the connection to the PCM interface is now closed when destroying
1090 an audio output device
1091 - files with slash in their path or filename could not be loaded
1092
1093 * test cases:
1094 - updated and fixed (haven't been touched in a while)
1095
1096 Version 0.4.0 (24 November 2006)
1097
1098 * packaging changes:
1099 - changed deprecated copyright attribute to license; added ldconfig
1100 to post-(un)install steps; added devel package for liblinuxsampler;
1101 to linuxsampler.spec (RPM)
1102 - install necessary development header files for allowing 3rd party
1103 applications to link against liblinuxsampler
1104 - liblinuxsampler's API documentation can be generated with 'make docs'
1105 (Doxygen required)
1106 - added benchmark to automatically detect the best triangle LFO
1107 implementation (currently either an integer math solution or a
1108 di-harmonic approximation), automatic detection can be overriden
1109 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1110 configure script argument though (mandatory for cross-compilation)
1111 - do not automatically pick optimized gcc flags if the user already
1112 provided some on his own (as CXXFLAGS)
1113 - added compile time option to disable processing of All-Notes-Off MIDI
1114 messages
1115 - added compile time options to allow disabling the various audio and
1116 MIDI drivers
1117 - fixed automatic GCC CPU switch detection on PPC
1118 (patch by Ebrahim Mayat)
1119
1120 * Gigasampler format engine:
1121 - extensive synthesis optimization
1122 (reimplementation of EGs and LFO(s), removed synthesis parameter
1123 prerendering and the synthesis parameter matrix in general, splitting
1124 each audio fragment into subfragments now where each subfragment uses
1125 constant pitch and filter coefficients. The volume coefficient is
1126 linearly interpolated inside a subfragment, unless
1127 --disable-interpolate-volume is set.)
1128 - fine tuning of the EG modulation parameters
1129 - improved filter cutoff calculation by adding support for the
1130 following gig parameters: Cutoff freq (used when no cutoff
1131 controller is defined), Control invert, Minimum cutoff, Velocity
1132 curve and Velocity range. The keyboard tracking now scales
1133 cutoff frequency instead of resonance.
1134 - added support for gig parameter Resonance.
1135 - fixed bug in sysex handling (patch by Juan Linietsky)
1136 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1137 which can be overridden with --enable-global-attenuation
1138 - EG fixes: made the length of "attack hold" stage more
1139 accurate. Release stage can now start before attack stage
1140 ends. Cancel release didn't work when sustain was zero. Attack
1141 time now has a minimal value to prevent clicks.
1142 - fixed pitch changes larger than one octave
1143 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1144 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1145 all modes can be altered via standard GM messages, that is CC5 for
1146 altering portamento time, CC65 for enabling / disabling portamento
1147 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1148 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1149 parameter) and crossfade
1150 - added support for the "attenuation controller threshold" gig
1151 parameter
1152 - added smoothing of volume changes caused by control change
1153 messages
1154 - sample loop parameters are now taken from the DimensionRegion
1155 instead of the wave chunk
1156 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1157 not equal to a power of two
1158 - reimplementation of the filter algorithm. The new filter is more
1159 accurate and supports all gig filter types, including bandreject
1160 and lowpass turbo.
1161 - real support for 24 bit samples - samples are not truncated to
1162 16 bits anymore
1163 - support for aftertouch (channel pressure, not polyphonic
1164 aftertouch)
1165 - LFO1 behaviour fixed (dampening from max volume instead of
1166 amplifying from 0)
1167
1168 * LSCP server:
1169 - fixed application exit on broken pipe error (fixes bug #20)
1170 - fixed the notification messages delay due to lack of
1171 network activity (fixes bug #26)
1172 - fixed parser bug which occured on space(s) within device parameters
1173 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1174
1175 * audio driver:
1176 - added aRts audio output driver (by no means RT safe)
1177
1178 * MIDI driver:
1179 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1180 messages several times instead of once
1181 - API extension for MIDI drivers which already supply exact time stamps
1182 for events (i.e. for offline rendering based MIDI drivers)
1183 - added checks for bad MIDI data
1184
1185 * linuxsampler application:
1186 - show available sampler engine types on startup
1187
1188 * general changes:
1189 - support for muting sampler channels and solo mode of the same, two new
1190 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1191 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1192 introduced for this, the behavior is the same like on a mixer console
1193 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1194 --enable-process-muted-channels which can be used to enable the
1195 processing of muted channels.
1196 - support for sostenuto pedal
1197 - support for monitoring the total number of active voices
1198 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1199 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1200 - fixed some memory management errors
1201 - fixed some concurrency problems that could lead to crashes when
1202 LSCP commands were executed
1203 - fixed crash when instrument loading failed previously on the same
1204 sampler channel (fixes bug #36)
1205
1206 Version 0.3.3 (15 July 2005)
1207
1208 * packaging changes:
1209 - fixed compilation with gcc 4.0
1210
1211 * Gigasampler format engine:
1212 - LFO preprocessing was performed even though the respective LFO was
1213 disabled by the instrument patch (minor efficiency fix)
1214 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1215 for volume ramp downs in the same fragment (needed for current voice
1216 stealing implementation) then simply inform the user with a warning
1217 about possible click sounds and reduce the volume ramp down
1218 appropriately instead of cancelling the audio device connection
1219
1220 Version 0.3.2 (24 June 2005)
1221
1222 * packaging changes:
1223 - updated autotools build files to compile on OS X
1224 (conditional compilation of CoreMIDI and MidiShare drivers)
1225 - hand-crafted assembly optimization code can be disabled with
1226 './configure --disable-asm' (definitely not recommended)
1227 - fixed 'make dist' rule to include all necessary files
1228 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1229 (due to 'dist-bzip2' automake option)
1230
1231 * Gigasampler format engine:
1232 - support for the gig parameters for "release velocity response" curves
1233 - fine tuning of the EGADSR envelope
1234 - volume of release triggered samples now depends on note-on velocity,
1235 note length and gig parameter "release trigger decay" instead of
1236 note-off velocity.
1237 - revised voice stealing
1238 (fixes crash and endless loop caused by voice stealing)
1239 - don't reset scale tuning on instrument or audio output device change
1240 - handle key group conflicts right at the beginning of each fragment
1241 instead of when the respective voice is actually launched
1242 (fixes undefined behavior if stolen voices belonged to a key group -
1243 this case was followed by a "killed voice survived" error message)
1244 - fixed minor issue with null/silence samples
1245 (those stole voices even though they don't need a voice at all which
1246 resulted in "voice stealing didn't work out" messages)
1247 - don't reset volume, pan, pitch and MIDI controller values on
1248 instrument or audio output device change
1249
1250 * LSCP server:
1251 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1252 - fixed LSCP event "CHANNEL_INFO" notification
1253 (e.g. did not notify on volume changes or MIDI program change events)
1254
1255 * linuxsampler application:
1256 - added command line parameters --lscp-addr and --lscp-port to override
1257 default IP address and port of LSCP server
1258
1259 Version 0.3.1 (24 May 2005)
1260
1261 * initial release
