File size: 68604 byte(s)
* windows, 32-bit: fixed potential crashes by making sure the stack in
  sub threads is 16-byte aligned

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 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31 properly and thus were ignored for certain uses.
32 - Added new C++ API method
33 VirtualMidiDevice::SendChannelPressureToSampler().
34 - windows, 32-bit: fixed potential crashes by making sure the stack in
35 sub threads is 16-byte aligned
36
37 * packaging changes:
38 - removed unnecessary dependency to libuuid
39 (originated by libgig's usage of it)
40 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
41 auto detect whether it (sh/c)ould output its messages in color.
42
43 * Real-time instrument scripts:
44 - Implemented scheduler for delayed MIDI events and for suspended scripts.
45 - Built-in script function "wait()": implemented support for function's
46 "duration-us" argument, thus scripts using this function are now
47 correctly resumed after the requested amount of microseconds.
48 - Built-in script function "play_note()": implemented support for
49 function's "duration-us" argument, thus notes triggered with this
50 argument are now correctly released after the requested amount of
51 microseconds.
52 - Fix: script events were not cleared when engine channel was reset,
53 potentially causing undefined behavior.
54 - Fixed crash which happened when trying to reference an undeclared
55 variable.
56 - Built-in script function "play_note()": Added support for passing
57 special value -1 for "duration-us" argument, which will cause the
58 triggered note to be released once the original note was released.
59 - Instrument script classes now exported with the liblinuxsampler C++ API.
60 - Added new API method ScriptVM::syntaxHighlighting() which provides
61 a convenient syntax highlighting backend for external instrument
62 script editor applications.
63 - Added new C++ API class "ScriptVMFactory".
64 - Extended parser issues to provide not only first line and first
65 column, but also last line and last column of issue (thus marking
66 the precise span of the issue within the source code).
67 - Reload script automatically after being modified by an instrument
68 editor.
69 - NKSP language grammar correction: allow empty event handler bodies
70 like "on note end on".
71 - Implemented built-in script function "change_vol()".
72 - Implemented built-in script function "change_tune()".
73 - Implemented built-in script function "change_pan()".
74 - Implemented built-in script function "change_cutoff()".
75 - Implemented built-in script function "change_reso()".
76 - Implemented built-in script function "event_status()".
77 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
78 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
79 "event_status()" function.
80 - NKSP language: Added support for bitwise operators ".or.", ".and."
81 and ".not.".
82 - NKSP language scanner: Fixed IDs matching to require at least one
83 character (i.e. when matching function names or variable names).
84 - NKSP language scanner: disabled unusued rules.
85 - Fixed behavior of play_note() and note_off() functions which must
86 be distinguished engine internally from "real" MIDI note on/off
87 events in order to avoid misbehaviors like hanging notes.
88 - Implemented built-in script variable "$KSP_TIMER".
89 - Implemented built-in script variable "$NKSP_REAL_TIMER".
90 - Implemented built-in script variable "$NKSP_PERF_TIMER".
91 - Implemented built-in script variable "$ENGINE_UPTIME".
92 - Implemented built-in script function "inc()".
93 - Implemented built-in script function "dec()".
94 - NKSP language fix: division expressions were evaluated too often.
95 - NKSP language fix: string concatenation operator was right
96 associative instead of left (to right).
97 - NKSP language correction: allow empty statements in entire language
98 (i.e. "if end if").
99 - Implemented built-in script function "stop_wait()".
100 - Implemented built-in script variable "$NI_CALLBACK_ID".
101 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
102 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
103 - Added support for read-only built-in variables (respectively
104 handled by the script parser).
105 - Added built-in script constant "$NI_CB_TYPE_INIT".
106 - Added built-in script constant "$NI_CB_TYPE_NOTE".
107 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
108 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
109 - NKSP Language: Added support for user defined script functions.
110 - Implemented built-in script function "change_attack()".
111 - Implemented built-in script function "change_decay()".
112 - Implemented built-in script function "change_release()".
113 - Fixed all change_*() built-in script functions to apply their
114 synthesis parameter changes immediately in case the respective note
115 was triggered at the same time, instead of scheduling the parameter
116 change, especially because it would cause some parameter types's
117 changes either to be ramped (i.e. change_vol()) or other types even
118 to have not effect at all (i.e. change_attack()).
119 - Implemented built-in script function "sh_left()".
120 - Implemented built-in script function "sh_right()".
121 - Implemented built-in script function "min()".
122 - Implemented built-in script function "max()".
123 - NKSP Fix: "init" event handler was not always executed when a script
124 was loaded.
125 - NKSP built-in wait() script function: abort script execution if
126 a negative or zero wait time was passed as argument (since this is
127 a common indication of a bug either of the script or even of the
128 engine, which could lead to RT instability or even worse).
129 - ScriptVM: Implemented automatic suspension of RT safety
130 threatening scripts.
131 - Provide more user friendly error messages on syntax errors.
132 - Fixed NKSP parser warning "Not a statement" when assigning an
133 initializer list to an array variable.

173 in order to get rid of warnings from automake 1.14
174
175 * general changes:
176 - Refactoring: moved the independent code from
177 the Gigasampler format engine to base classes
178 - command line option '--profile' is currently disabled, since the
179 respective profiling code is currently broken
180 - Introduced support for optional environment variable
181 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
182 where the sampler shall look for instrument editor plugins
183 (patch by Luis Garrido, slightly modified).
184 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
185 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
186 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
187 note (in this implementation of the sampler its simply hard routed to
188 the 1st effect send of the sampler channel, no matter what the actual
189 effect type is)
190 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
191 note (in this implementation of the sampler its simply hard routed to
192 the 2nd effect send of the sampler channel, no matter what the actual
193 effect type is)
194 - implemented support for internal LADSPA effects
195 - raised limit of program change queue from 100 to 512
196 (as suggested by Alex Stone)
197 - implemented sine LFO, pulse LFO and saw LFO
198 - experimental support for per voice equalization
199 - added command line option --exec-after-init
200 - Introduced new C++ API method:
201 EngineChannel::InstrumentFileName(int index)
202 allowing to retrieve the whole list of files used for the loaded
203 instrument on an engine channel (a.k.a. part). Some GigaStudio
204 instruments for example are splitted over several files like
205 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
206 - Added new C++ API method Sampler::GetGlobalMaxVoices().
207 - Added new C++ API method Sampler::GetGlobalMaxStreams().
208 - Added new C++ API method Sampler::SetGlobalMaxVoices().
209 - Added new C++ API method Sampler::SetGlobalMaxStreams().
210 - Various "const" and "restrict" optimizations.
211 - all engines: add pan CC value to instrument pan parameter before
212 applying panning, instead of using two separate pan functions in
213 series (#182)
214 - added a lock guard class for exception safe mutex handling and
215 used it everywhere appropriate
216 - Immediately apply scale tuning changes to active voices.
217 - Exposed scale tuning to C++ API (along to the already existing standard
218 SysEx way).
219 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
220 and broken for ppc64. (Seq_cst loads and stores are actually not
221 used in LS, so the bug wasn't noticable.)
222 - lsatomic.h: added ARMv7 support
223 - Added support for multiple MIDI input ports per sampler channel (and
224 added various new C++ methods for this new feature / design change, old
225 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
226 as deprecated but are still there and should provide full behavior
227 backward compatibility).
228 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
229 unsafe and caused compilation error with clang 2.x).
230 - Bugfix: only process the latest MIDI program change event.
231 - Introducing the LSCP shell, which provides convenient control of the
232 sampler from the command line by providing LSCP aware features.
233 - VirtualMidiDevice: Added support for program change.
234 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
235 - VirtualMidiDevice: Added support for pitch bend.
236 - Aftertouch: extended API to explicitly handle channel pressure and
237 polyphonic key pressure events (so far polyphonic pressure was not
238 supported at all, and channel pressure was rerouted as CC128 but not
239 used so far).
240 - Added initial support for real-time instrument scripts. The script VM
241 code is shared by all sampler engine implemementations, however only the
242 gig file format currently provides support for storing instrument scripts
243 (as LinuxSampler extension to the original GigaStudio 4 format).
244
245 * Gigasampler format engine:
246 - implemented the "round robin keyboard" dimension
247 - fixed round robin and random dimensions for cases when number of
248 dimension zones is not a power of two
249 - made round robin use a counter for each region instead of each
250 key
251 - bugfix: pitch LFO controller "internal+aftertouch" was broken
252 - bugfix: filter keyboard tracking was broken
253 - filter performance fix (an unnecessary copy was made of the
254 filter parameters in each sub fragment)
255 - handle special case when pan parameter in gig file has max or
256 min value
257 - Exclusive Groups: don't ever stop voices of the same note,
258 doesn't sound naturally with a drumkit
259 - fixed EG1 modulation when attack or release is zero
260 - Fixed support for 'aftertouch' attenuation controller.
261 - Fixed crash that happened with velocity split sounds under certain
262 conditions (see also previous commit on libgig).
263 - fixed behaviour of filter LFO
264
265 * SFZ format engine:
266 - Initial implementation (not usable yet)

271 - added support for trigger=first, trigger=legato and sw_previous
272 - allow non-numerical key values ("C#4" for example)
273 - "key" opcode now sets pitch_keycenter too
274 - fixed error when unloading instrument with same sample used by
275 multiple regions
276 - added some opcode aliases, like loopmode for loop_mode, to be
277 more compatible
278 - added support for trigger=release and rt_decay

288 - reduced memory usage for sfz data
289 - RT-safeness: avoid malloc in audio thread
290 - fixed a bug that could cause voice stealing to fail
291 - optimized sample lookup
292 - improved support for exclusive groups (group, off_by and
293 off_mode)
294 - added support for controller triggered regions (on_locc/on_hicc)
295 - added support for loop_mode=one_shot
296 - fixed playback of 16 bit wav files on big endian CPUs
297 - added support for Ogg Vorbis sample files
298 - use loop markers from sample file if loop_start and loop_end are
299 not set in sfz file
300 - implemeted filters. Filter types: lowpass, bandpass, bandreject

440 - AU bugfix: failed to destroy its audio/MIDI devices
441 - Listen to all interfaces on Mac OS X (INADDR_ANY)
442 - VST bugfix: If the host called resume() before and after
443 changing sample rate or block size, the number of channels was
444 incorrectly set to two. This caused silence in Cubase 5.
445 - save engine type (gig, sfz or sf2) in plugin state
446 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
447 64 bit Windows

478 informations like the EngineChannel for which the instrument editor was
479 spawned for. This allows the instrument editors to interact more actively
480 with the sampler.
481
482 * MIDI driver:
483 - ALSA MIDI driver supports now "NAME" device parameter, for overriding

493 the driver will automatically connect to other CoreMIDI clients' ports
494 (e.g. external MIDI devices being attached to the Mac)
495 - added support for MIDI note on velocity filter
496 - CoreMIDI: fixed memory deallocation error
497 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
498 virtual keyboards in frontends / instrument editors being stuck.
499 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

626 channel to a different engine type
627 - fixed crash when deleting a sampler channel or changing engine
628 type while an instrument load was in progress
629 - bugfix: playing a note while changing the instrument could cause
630 a crash, or give "Handing back unknown region" error messages
631 - bugfix: calling SET VOICES (which Fantasia does on start and
632 refresh) could cause instruments to be unloaded
633 - Mac OS X: fixed name collision of enum in EffectControl and
634 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
635 - Mac OS X: fixed hanging threads
636 - Windows: disabled the previous thread fix on non-Mac systems, as
637 it caused hanging threads on Windows
638 - Fixed possible crashes due to corrupted MIDI/audio device list
639 after MIDI/audio device creation failure
640 - When creating MIDI instrument map entries with "PERSISTENT" type, the
641 instruments were uselessly precached with zero samples, however it still
642 took the full preloading time and on 1st program change the respective
643 instrument was completely reloaded again.
644 - fixed handling of rapid bank select and program change messages
645 sent to the same sampler channel (patch from the Open Octave
646 project, slightly adjusted)

661 playing a note in a key group
662 - fixed erroneous error message piping in VoiceBase.h
663 (labelled "Disk stream not available in time")
664 - Update effects on sample rate & period size changes (to avoid
665 crashes and noise on such transitions).
666 - ignore missing LADSPA paths without ignoring valid LADSPA paths
667 (fixes #208)
668 - Fixed bug in LSCP grammar definition which caused a statement like
669 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
670 practically irrelevant, however it caused problems with the new LSCP
671 shell's auto completion feature).
672 - Fixed MIDI program change messages being ignored if quickly executed
673 after each other (fixes #231).
674
675 Version 1.0.0 (31 July 2009)
676
677 * packaging changes:
678 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

688 - minor fix in configure for mmsystem.h detection on MinGW
689 - Windows: look for editor plugins and Fantasia using base
690 directory of liblinuxsampler dll (look in the same directory and one
691 directory above)
692 - configure script fix: removed unconditional use of SSE
693 - fixed building with sqlite installed in a non-standard directory
694 - when cross-compiling, don't try to create instruments.db
695 - fix for new mingw-w64 version, which has usleep
696
697 * general changes:
698 - bugfix: on some POSIX systems instrument editor plugins refused to
699 load as we used a non-portable Linux specific struct field
700 (fixes bug #70, patch by Ronald Baljeu)
701 - fixed endless loop which occured when loading an instrument editor
702 plugin DLL on Windows systems failed
703 - fixed memory leaks that occurred when liblinuxsampler was unloaded
704 - optimized the SynchronizedConfig class so it doesn't wait
705 unnecessarily long after an update
706 - added support for notifying instrument editors on note-on / note-off
707 events (e.g. to highlight the pressed keys on the virtual keyboard
708 of gigedit)
709 - added support for triggering notes by instrument editors (see above)
710 - be verbose on DLL load errors (on Linux)
711 - fixed di-harmonic triangle LFO implementation (this LFO implementation
712 is only used by very few systems, most pick the int math
713 implementation, which is usually faster)
714 - fixes for audio drivers with varying buffer sizes
715 - experimental support for running LinuxSampler as a DSSI, LV2 and
716 VST plugin
717 - notification events for stream/voice count statistics are now sent
718 only when there are actual changes
719 - added memory ordering constraints to improve stability on
720 multi-core and multi-cpu systems
721 - maximum voices and disk streams can now be altered at runtime
722 - fixed CPU feature detection on x86_64 (maybe fixes #108)
723 - automatic stacktrace mechanism is now turned off by default and can
724 be switched on by command line option "--stacktrace" (the automatic
725 stacktrace mechanism seems to be broken on most systems at the moment)
726 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
727 a pointer to the launched InstrumentEditor object
728 - added optional 3rd party user data parameter for following
729 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
730 InstrumentEditor::Launch(),
731 InstrumentManager::LaunchInstrumentEditor()
732 - theoretical fix: made SynchronizedConfig follow C++0x memory
733 model more strictly
734 - fixes for using large audio device buffers
735 - Windows: add the installation directory to the DLL search path
736 when loading an editor plugin (solves problems with VST and
737 gigedit on systems with other GTK versions installed)
738 - updated linuxsampler man page
739
740 * audio driver:
741 - removed the nonsense audio channel constraint (which was hard coded to
742 max. 100 audio channels) for most audio drivers
743 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
744 opposed to the LSCP specs
745 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
746 reflected the wrong value
747 - fixed a memory management bug in ASIO driver
748 - Makefile fix: JACK_CFLAGS wasn't used
749 - JACK: use jack_client_open instead of the deprecated
750 jack_client_new

756 win64)
757 - VST: added support for sample rate and buffer size changes
758 - VST: close editor (Fantasia) when the VST is removed
759 - VST: avoid opening Fantasia more than once for each VST instance
760 - VST: export main function as "main" on Linux too (fix for
761 energyXT)
762 - VST: changed number of output channels from one stereo to 16
763 stereo
764 - added channel routing, fxsends and midi maps to the settings
765 stored in the plugin state
766 - performance optimization of AudioChannel::MixTo() and
767 AudioChannel::CopyTo() methods using GCC vector exensions
768 (if available)
769 - ASIO fixes: avoid initializing the device twice, avoid throwing
770 exception when getting parameters from a disconnected device
771
772 * MIDI driver:
773 - added JACK MIDI driver
774 - dispatch bank select as ordinary CC as well, the user might seriously
775 want to (mis)use it for some purpose ("fixed" in all current MIDI
776 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
777 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
778 CoreMidi or AU
779 - fixed mingw-w64 compilation error in MME driver
780 - made program change handling in MIDI thread real-time safe by
781 moving the logic to a non-RT thread
782 - fixed minor memory leak in ALSA driver
783
784 * instruments database:
785 - avoid time consuming samples scanning when adding instruments
786 to the instruments database

791 - work-around for missing fnmatch function on Windows to make
792 instrument database compilable
793 - added instrument database support on Windows
794 works with both standalone mode and VST plugin.
795 the instruments DB file is located in
796 %USERPROFILE%\.linuxsampler\instruments.db which allows different
797 databases for each windows user
798 if no DB is present it automatically creates the .linuxsampler subdir
799 and then creates an empty DB
800 - fixed recursive import, which was broken on Windows
801
802 * Gigasampler format engine:
803 - fixed a memory leak that could happen when a channel was deleted
804 while notes were playing
805 - made it possible to load an instrument even if the audio thread
806 isn't running
807 - added partial support for the "Controller Triggered" MIDI rule,
808 enough for piano gigs with pedal noise samples
809 - minor fix: only mark FX sends as being modified if really the
810 respective FX send MIDI controller was used
811 - added support for GM global device volume SysEx message
812 (can be selected at compile time to either apply globally to the
813 whole sampler [default] or only to the sampler channels that are
814 connected to the respective MIDI input port the SysEx message arrived
815 on)
816 - bugfix: notes triggered at position 0 in the audio buffer were
817 sometimes wrongly killed in the same buffer, causing no sound to
818 be played
819 - added support for chromatic / drumkit mode Roland GS Sysex message
820 which is usally used to switch a part between chromatic sounds and
821 drumkit sounds (as opposed to their common default setting of MIDI
822 part 10 being a drumkit part and all other ones chromatic parts), in
823 LS however one can switch between the first 16 MIDI instrument maps
824 defined for the sampler
825 - made it possible to create multiple sample channels even if the
826 audio thread isn't running
827 - fixed crash when removing channel with active voices (#116)
828 - bugfix: on sample reference changes (instrument editor), only
829 un-cache the respective sample if it's really not used by any
830 sampler engine anymore
831 - re-cache samples in case they were changed by an instrument editor,
832 e.g. when a sample was added while playing (#82)
833 - fixed hanging notes which occured when note-off event had the exact
834 same time stamp as the voice's note-on event and occured both in the
835 same audio fragment cycle (fixes bug #112)
836 - added support for the "fine tune" and "pitch bend range"
837 instrument-level gig parameters
838 - fixed minor artifacts in pitch bend handling
839 - added support for GS Reset SysEx message
840 - allow gig files to use unlimited downward pitch shifting
841 - added a limit check for upward pitch shifting
842 - bugfix: sometimes, when playing a note twice fast, the second
843 note was silent
844 - fixed crash happening when a pitch bend event arrived at the
845 same time a new instrument was loading
846
847 * LSCP server:
848 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
849 react on MIDI data arriving on certain sampler channels (so far only
850 Note-On and Note-Off events are sent via this LSCP event)
851 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
852 react on MIDI data arriving on certain MIDI input devices (so far only
853 Note-On and Note-Off events are sent via this LSCP event)
854 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
855 SET DB_INSTRUMENT FILE_PATH
856 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
857 frontends to send MIDI messages to specific sampler channel
858 - added two additional fields to GET FILE INSTRUMENT INFO command -
859 KEY_BINDINGS and KEYSWITCH_BINDINGS
860 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
861 was incorrect
862 - Optimized the retrieval of the MIDI instrument mappings
863 - added new LSCP command "SET VOICES" to globally alter the maximum
864 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
865 be triggered respectively
866 - added new LSCP command "SET STREAMS" to globally alter the maximum
867 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
868 which will be triggered respectively
869 - bugfix: retry if "select" returns EINTR (this fixes a crash when
870 a gigedit file dialog is opened)
871 - close all connections when LSCPServer is deleted
872 - hard close of all sockets on exit
873 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
874 driver
875
876 * Bug fixes:
877 - fixed a crash which occurs when removing a sampler channel waiting
878 to start instrument loading after another channel
879 - fixed a crash which occurs when removing a sampler channel with
880 instrument loading in progress (bug #113)
881 - fixed termination caused by uncaught exception when adding MIDI
882 instrument with PERSISTENT load mode
883 - fixed possible iterator invalidations when resetting the sampler
884 - fixed memory leaks when issuing the following LSCP commands:
885 GET AUDIO_OUTPUT_DRIVER INFO
886 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
887 GET MIDI_INPUT_DRIVER INFO
888 GET MIDI_INPUT_DRIVER_PARAMETER INFO
889 - fixed possible compilation error when sqlite is not present
890 - fixed orphaned pointers when setting maximum voices limit (bug #118)
891 - fixed crash when changing the audio output device of a sampler
892 channel with loaded instrument and start playing notes
893 - fixed endless loop in Engine::SuspendAll() (bug #120)
894 - fixed a low-level atomic load function that was broken on 64-bit
895 PowerPC, which probably could cause crashes on that platform
896 - fixed a memory management error which could cause a crash when a
897 plugin was unloaded
898 - bugfix: two private structs had the same name, which could cause
899 problems if the linker chose the wrong constructor
900 - fixed low-level ConditionServer usage bug that caused lockups on
901 Windows
902
903
904 Version 0.5.1 (6 December 2007)
905
906 * packaging changes:
907 - added autoconf checks for pthread library
908 - added autoconf check for pthread bug found on certain NPTL-enabled
909 glibc versions (see Gentoo bug report #194076)
910 - added autoconf checks for MS Windows
911
912 * general changes:
913 - bugfix: the thread used by an editor plugin didn't die when the
914 editor closed
915 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
916 out all the space. operator--() did not apply size_mask after
917 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
918 order to avoid problems with the _NonVolatileReader functions.
919 - bugfix: Stream.h: added a missing divide by BytesPerSample in
920 GetWriteSpace(). Since this function is currently only used in
921 the stream's qsort() compare function, it didn't trigger any
922 bugs.
923 - Resampler.h, Synthesizer.h: cubic interpolation now works in
924 24bit mode too. Faster method to read 24bit words on little
925 endian machines (x86): replaced 3 byte reads + shifts with a 1
926 unaligned 32bit read and shift
927 - experimental support for MS Windows (MIDI input via MME, AUDIO
928 output via ASIO)
929 - made handling of SIGINT signal (Ctrl-C) a bit more robust
930 - support for monitoring the total number of active disk streams
931 (new LSCP commands: GET TOTAL_STREAM_COUNT,
932 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
933
934 * AUDIO driver:
935 - added Windows ASIO low latency audio driver
936
937 * MIDI driver:
938 - added MME Windows MIDI driver
939
940 * LSCP server:
941 - added support for Windows style path / filenames, however with
942 forward slash path separators instead of backslash
943 (i.e. "C:/foo/bar.gig")
944 - allow naughty liblscp to send non-string device parameters within
945 apostrophes as well
946 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
947 "LIST FILE INSTRUMENTS <file>" and
948 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
949 about an arbitrary instrument file on the system where the sampler is
950 running on
951
952 Version 0.5.0 (15 October 2007)
953
954 * packaging changes:
955 - config.h is not going to be installed along with liblinuxsampler's
956 API header files anymore
957 - only the API relevant header (and source) files will be exported to
958 the Doxygen API documentation (explicitly listed in Doxyfile.in)
959 - added completely new XCode project files for Mac OSX which is now
960 capable to execute our autoconf environment, thus no need anymore
961 to maintain the compile time configuration file (osx/version.h) for
962 OSX manually (patch by Toshi Nagata)
963 - fixed buggy boolean --enable-foo / --disable-foo configure script
964 parameters
965 - global.h now only covers global definitions that are needed for the
966 C++ API header files, all implementation internal global definitions
967 are now in global_private.h
968 - atomic.h is not exposed to the C++ API anymore
969 - no need to include config.h anymore for using LS's API header files
970 - fixed warnings in API doc generation
971
972 * general changes:
973 - replaced the old, confusing MIDI program change mechanism by a
974 flexible MIDI instrument mapper which allows to map arbitrary
975 (MIDI bank, MIDI program) pairs with arbitrary
976 (engine type, instrument file, file index) triplets which will be
977 loaded on the respective channel when such MIDI program change
978 messages arrive, beside that, each entry allows to define a life-time
979 strategy for the instrument, so the user can define whether the
980 instrument should i.e. be permanently loaded (to be able to switch
981 quickly among sounds) or i.e. loaded just on demand when the
982 respective program change arrives (to safe RAM space), as well as a
983 global volume factor for each entry, so the user can adjust the volume
984 dynamic of his mapped instrument collection without having to modify
985 the instrument files, also one can manage arbitrary amount of such
986 MIDI instrument maps and assign each sampler channel individually
987 a certain map, so that i.e. separation of normal instruments and
988 drumkits is possible
989 - new notification events for tracking changes to audio/MIDI devices,
990 MIDI instrument maps, MIDI instruments, FX sends, global volume.
991 - sampler was limited to load max. 200 instruments in the background
992 due to a constant size RingBuffer FIFO which is now replaced by a
993 dynamic (unlimited) size std::list FIFO
994 - added FX sends, these allow to route audio signals to arbitrary audio
995 output channels for being processed by external effect processors
996 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
997 controllers
998 - global (sampler wide) volume can now be controlled at runtime
999 - Implemented new, improved notification system
1000 - fixed compilation errors regarding OSX
1001 (patch by Toshi Nagata)
1002 - implemented instruments database
1003 - added support for escape sequences to the instruments database
1004 - added highly experimental support for on-the-fly instrument editing
1005 within the sampler's process (by using instrument editor plugins),
1006 you'll notice the new "Registered instrument editors:" message on
1007 startup, added a new LSCP command:
1008 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1009 to spawn a matching instrument editor for the instrument on the
1010 given sampler channel, the plugin path can be overridden at compile
1011 time with ./configure --enable-plugin-dir=/some/dir
1012 - added experimental code for synchronizing instrument editors hosted
1013 in the sampler's process to safely edit instruments while playing
1014 without a crash (hopefully) by either suspending single regions
1015 wherever possible or if unavoidable whole engine(s)
1016 - fixed several issues in fundamental "Thread" class: set scheduling
1017 policy and priority on thread level, set a minimum stack size for
1018 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1019 threads simply inherited properties of starting thread instead of
1020 setting their own policy and priority
1021 - minor fix in our automatic stack trace mechanism on crashes, the
1022 main process did not wait for the stack trace process to finish
1023 its output
1024 - fixed some minor memory leaks
1025 - reenabled assembly features support, at the moment only for
1026 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1027 - minor assembly fix in x86 features detection (don't use the PIC
1028 register, to avoid relocations in the text segment at runtime)
1029 - POSIX callback functions of Thread.h are hidden
1030
1031 * MIDI driver:
1032 - dispatch bank select (MSB and LSB) messages
1033
1034 * audio driver:
1035 - the ALSA audio output driver parameters now reflect the correct
1036 parameter value ranges for the respective selected sound card
1037 (patch by Till Wimmer, a bit fixed and extended)
1038
1039 * Gigasampler format engine:
1040 - if a filter is used and EG2 finishes before EG1, let the voice
1041 die when EG2 has finished (this fixes a problem with clicks and
1042 voice starvation for some gigs)
1043 - playback is no longer disabled during instrument loading
1044 - all notes playing on a channel that changes its instrument keep
1045 playing with the old instrument until they get a note off
1046 command
1047 - EG fix: a release value of zero could cause noises or crash
1048 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1049 - EG fine tuning: when attack is zero the EG starts at a level
1050 above max sustain level, which means that there is a decay phase
1051 even if sustain is 100%
1052 - more EG fixes: the level could sometimes go below zero and cause
1053 noises or crashes
1054 - minor fix of EGDecay (patch by Toshi Nagata)
1055 - fixed compiler error when --enable-override-filter-type was
1056 supplied to the configure script (fixes #46)
1057 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1058 instead of a fix value
1059 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1060 127 (solo mode) only kill voices if the respective mode really
1061 changed
1062
1063 * LSCP server:
1064 - fixed compile time error for old Bison versions
1065 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1066 - parser now supports extended ASCII character set
1067 (up to ASCII code 255, i.e. includes now umlauts and accents)
1068 - filename arguments in LSCP commands now allow to use escape
1069 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1070 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1071 code value like \xf2) (fixes bug #24)
1072 - the following LSCP commands now also support escape sequences for at
1073 least one of their text-based parameters (i.e. name, description):
1074 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1075 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1076 "SET DB_INSTRUMENT_DIRECTORY NAME",
1077 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1078 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1079 "FIND DB_INSTRUMENT_DIRECTORIES"
1080 - returns verbose syntax errors (line and column where syntax error
1081 occured, the unexpected character and the actually expected, possible
1082 character(s), the latter only if less than 5 possibilities)
1083 - made sure that LSCP syntax is not affected by gigedit locale
1084 settings
1085 - bugfix regarding strings parameter lists: all comma separated lists
1086 of strings were treated as being one string containing commas
1087 (fixes #57)
1088
1089 * Bug fixes:
1090 - fixed crash occurring on certain LSCP scripts (Bug 39)
1091 - another thread safety fix for lscp "load engine" and "set
1092 channel audio output device"
1093 - fixed a crash which occurs when reassigning the same engine
1094 on a sampler channel with connected MIDI device
1095 - fixed a crash which occurs when changing the number of ports of a MIDI
1096 device connected to a sampler channel to number less then or equal
1097 to the index of the port to which the sampler channel is connected.
1098 - The previous bindings were not been disconnected when altering
1099 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1100 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1101 - The active stream/voice count statistic was incorrect.
1102 - notification events were not been sent for some sampler
1103 channel changes
1104 - added default min and max values to restrict the number of allowed
1105 audio output channels and MIDI input ports
1106 - the connection to the PCM interface is now closed when destroying
1107 an audio output device
1108 - files with slash in their path or filename could not be loaded
1109
1110 * test cases:
1111 - updated and fixed (haven't been touched in a while)
1112
1113 Version 0.4.0 (24 November 2006)
1114
1115 * packaging changes:
1116 - changed deprecated copyright attribute to license; added ldconfig
1117 to post-(un)install steps; added devel package for liblinuxsampler;
1118 to linuxsampler.spec (RPM)
1119 - install necessary development header files for allowing 3rd party
1120 applications to link against liblinuxsampler
1121 - liblinuxsampler's API documentation can be generated with 'make docs'
1122 (Doxygen required)
1123 - added benchmark to automatically detect the best triangle LFO
1124 implementation (currently either an integer math solution or a
1125 di-harmonic approximation), automatic detection can be overriden
1126 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1127 configure script argument though (mandatory for cross-compilation)
1128 - do not automatically pick optimized gcc flags if the user already
1129 provided some on his own (as CXXFLAGS)
1130 - added compile time option to disable processing of All-Notes-Off MIDI
1131 messages
1132 - added compile time options to allow disabling the various audio and
1133 MIDI drivers
1134 - fixed automatic GCC CPU switch detection on PPC
1135 (patch by Ebrahim Mayat)
1136
1137 * Gigasampler format engine:
1138 - extensive synthesis optimization
1139 (reimplementation of EGs and LFO(s), removed synthesis parameter
1140 prerendering and the synthesis parameter matrix in general, splitting
1141 each audio fragment into subfragments now where each subfragment uses
1142 constant pitch and filter coefficients. The volume coefficient is
1143 linearly interpolated inside a subfragment, unless
1144 --disable-interpolate-volume is set.)
1145 - fine tuning of the EG modulation parameters
1146 - improved filter cutoff calculation by adding support for the
1147 following gig parameters: Cutoff freq (used when no cutoff
1148 controller is defined), Control invert, Minimum cutoff, Velocity
1149 curve and Velocity range. The keyboard tracking now scales
1150 cutoff frequency instead of resonance.
1151 - added support for gig parameter Resonance.
1152 - fixed bug in sysex handling (patch by Juan Linietsky)
1153 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1154 which can be overridden with --enable-global-attenuation
1155 - EG fixes: made the length of "attack hold" stage more
1156 accurate. Release stage can now start before attack stage
1157 ends. Cancel release didn't work when sustain was zero. Attack
1158 time now has a minimal value to prevent clicks.
1159 - fixed pitch changes larger than one octave
1160 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1161 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1162 all modes can be altered via standard GM messages, that is CC5 for
1163 altering portamento time, CC65 for enabling / disabling portamento
1164 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1165 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1166 parameter) and crossfade
1167 - added support for the "attenuation controller threshold" gig
1168 parameter
1169 - added smoothing of volume changes caused by control change
1170 messages
1171 - sample loop parameters are now taken from the DimensionRegion
1172 instead of the wave chunk
1173 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1174 not equal to a power of two
1175 - reimplementation of the filter algorithm. The new filter is more
1176 accurate and supports all gig filter types, including bandreject
1177 and lowpass turbo.
1178 - real support for 24 bit samples - samples are not truncated to
1179 16 bits anymore
1180 - support for aftertouch (channel pressure, not polyphonic
1181 aftertouch)
1182 - LFO1 behaviour fixed (dampening from max volume instead of
1183 amplifying from 0)
1184
1185 * LSCP server:
1186 - fixed application exit on broken pipe error (fixes bug #20)
1187 - fixed the notification messages delay due to lack of
1188 network activity (fixes bug #26)
1189 - fixed parser bug which occured on space(s) within device parameters
1190 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1191
1192 * audio driver:
1193 - added aRts audio output driver (by no means RT safe)
1194
1195 * MIDI driver:
1196 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1197 messages several times instead of once
1198 - API extension for MIDI drivers which already supply exact time stamps
1199 for events (i.e. for offline rendering based MIDI drivers)
1200 - added checks for bad MIDI data
1201
1202 * linuxsampler application:
1203 - show available sampler engine types on startup
1204
1205 * general changes:
1206 - support for muting sampler channels and solo mode of the same, two new
1207 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1208 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1209 introduced for this, the behavior is the same like on a mixer console
1210 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1211 --enable-process-muted-channels which can be used to enable the
1212 processing of muted channels.
1213 - support for sostenuto pedal
1214 - support for monitoring the total number of active voices
1215 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1216 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1217 - fixed some memory management errors
1218 - fixed some concurrency problems that could lead to crashes when
1219 LSCP commands were executed
1220 - fixed crash when instrument loading failed previously on the same
1221 sampler channel (fixes bug #36)
1222
1223 Version 0.3.3 (15 July 2005)
1224
1225 * packaging changes:
1226 - fixed compilation with gcc 4.0
1227
1228 * Gigasampler format engine:
1229 - LFO preprocessing was performed even though the respective LFO was
1230 disabled by the instrument patch (minor efficiency fix)
1231 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1232 for volume ramp downs in the same fragment (needed for current voice
1233 stealing implementation) then simply inform the user with a warning
1234 about possible click sounds and reduce the volume ramp down
1235 appropriately instead of cancelling the audio device connection
1236
1237 Version 0.3.2 (24 June 2005)
1238
1239 * packaging changes:
1240 - updated autotools build files to compile on OS X
1241 (conditional compilation of CoreMIDI and MidiShare drivers)
1242 - hand-crafted assembly optimization code can be disabled with
1243 './configure --disable-asm' (definitely not recommended)
1244 - fixed 'make dist' rule to include all necessary files
1245 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1246 (due to 'dist-bzip2' automake option)
1247
1248 * Gigasampler format engine:
1249 - support for the gig parameters for "release velocity response" curves
1250 - fine tuning of the EGADSR envelope
1251 - volume of release triggered samples now depends on note-on velocity,
1252 note length and gig parameter "release trigger decay" instead of
1253 note-off velocity.
1254 - revised voice stealing
1255 (fixes crash and endless loop caused by voice stealing)
1256 - don't reset scale tuning on instrument or audio output device change
1257 - handle key group conflicts right at the beginning of each fragment
1258 instead of when the respective voice is actually launched
1259 (fixes undefined behavior if stolen voices belonged to a key group -
1260 this case was followed by a "killed voice survived" error message)
1261 - fixed minor issue with null/silence samples
1262 (those stole voices even though they don't need a voice at all which
1263 resulted in "voice stealing didn't work out" messages)
1264 - don't reset volume, pan, pitch and MIDI controller values on
1265 instrument or audio output device change
1266
1267 * LSCP server:
1268 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1269 - fixed LSCP event "CHANNEL_INFO" notification
1270 (e.g. did not notify on volume changes or MIDI program change events)
1271
1272 * linuxsampler application:
1273 - added command line parameters --lscp-addr and --lscp-port to override
1274 default IP address and port of LSCP server
1275
1276 Version 0.3.1 (24 May 2005)
1277
1278 * initial release
