File size: 69027 byte(s)
* Gig Engine: Fixed clicks and pumping noise with Lowpass Turbo filter
  on very low cutoff settings.
* Bumped version (2.0.0.svn34).

1 Version SVN trunk (?)
2
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
5
6 * Gigasampler format engine:
7 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
8 cutoff settings.
9
10 * general changes:
11 - fixed printf type errors (mostly in debug messages)
12 - use unique_ptr instead of auto_ptr when building with C++11
13 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
14 allowing to sort data efficiently in real-time safe manner.
15 - RTList class: added methods for moving/inserting elements to arbitrary
16 position within a list.
17 - RTList class: added method fromPtr() for creating an Iterator object from
18 a raw element pointer.
19 - Attempt to partly fix resetting engine channels vs. resetting engine, an
20 overall cleanup of the Reset*(), ConnectAudioDevice(),
21 DisconnectAudioDevice() API methods would still be desirable though,
22 because the current situation is still inconsistent and error prone.
23 - Active voices are now internally grouped to "Note" objects, instead of
24 being directly assigned to a keyboard key. This allows more fine graded
25 processing of voices, which is i.e. required for certain instrument
26 script features.
27 - Fix: Release trigger voices were not spawned on sustain pedal up
28 (CC #64) events.
29 - Fix: Release trigger voices can now also distinguish correctly between
30 note-off and sustain pedal up events.
31 - All engines: Increased ramp speed of volume smoother and pan smoother
32 (while slow rate of crossfade smoother is preserved) to allow quick
33 volume and pan changes by instrument scripts for instance.
34 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
35 properly and thus were ignored for certain uses.
36 - Added new C++ API method
37 VirtualMidiDevice::SendChannelPressureToSampler().
38 - windows, 32-bit: fixed potential crashes by making sure the stack in
39 sub threads is 16-byte aligned
40 - fixed numerous compiler warnings
41
42 * packaging changes:
43 - removed unnecessary dependency to libuuid
44 (originated by libgig's usage of it)
45 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
46 auto detect whether it (sh/c)ould output its messages in color.
47
48 * Real-time instrument scripts:
49 - Implemented scheduler for delayed MIDI events and for suspended scripts.
50 - Built-in script function "wait()": implemented support for function's
51 "duration-us" argument, thus scripts using this function are now
52 correctly resumed after the requested amount of microseconds.
53 - Built-in script function "play_note()": implemented support for
54 function's "duration-us" argument, thus notes triggered with this
55 argument are now correctly released after the requested amount of
56 microseconds.
57 - Fix: script events were not cleared when engine channel was reset,
58 potentially causing undefined behavior.
59 - Fixed crash which happened when trying to reference an undeclared
60 variable.
61 - Built-in script function "play_note()": Added support for passing
62 special value -1 for "duration-us" argument, which will cause the
63 triggered note to be released once the original note was released.
64 - Instrument script classes now exported with the liblinuxsampler C++ API.
65 - Added new API method ScriptVM::syntaxHighlighting() which provides
66 a convenient syntax highlighting backend for external instrument
67 script editor applications.
68 - Added new C++ API class "ScriptVMFactory".
69 - Extended parser issues to provide not only first line and first
70 column, but also last line and last column of issue (thus marking
71 the precise span of the issue within the source code).
72 - Reload script automatically after being modified by an instrument
73 editor.
74 - NKSP language grammar correction: allow empty event handler bodies
75 like "on note end on".
76 - Implemented built-in script function "change_vol()".
77 - Implemented built-in script function "change_tune()".
78 - Implemented built-in script function "change_pan()".
79 - Implemented built-in script function "change_cutoff()".
80 - Implemented built-in script function "change_reso()".
81 - Implemented built-in script function "event_status()".
82 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
83 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
84 "event_status()" function.
85 - NKSP language: Added support for bitwise operators ".or.", ".and."
86 and ".not.".
87 - NKSP language scanner: Fixed IDs matching to require at least one
88 character (i.e. when matching function names or variable names).
89 - NKSP language scanner: disabled unusued rules.
90 - Fixed behavior of play_note() and note_off() functions which must
91 be distinguished engine internally from "real" MIDI note on/off
92 events in order to avoid misbehaviors like hanging notes.
93 - Implemented built-in script variable "$KSP_TIMER".
94 - Implemented built-in script variable "$NKSP_REAL_TIMER".
95 - Implemented built-in script variable "$NKSP_PERF_TIMER".
96 - Implemented built-in script variable "$ENGINE_UPTIME".
97 - Implemented built-in script function "inc()".
98 - Implemented built-in script function "dec()".
99 - NKSP language fix: division expressions were evaluated too often.
100 - NKSP language fix: string concatenation operator was right
101 associative instead of left (to right).
102 - NKSP language correction: allow empty statements in entire language
103 (i.e. "if end if").
104 - Implemented built-in script function "stop_wait()".
105 - Implemented built-in script variable "$NI_CALLBACK_ID".
106 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
107 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
108 - Added support for read-only built-in variables (respectively
109 handled by the script parser).
110 - Added built-in script constant "$NI_CB_TYPE_INIT".
111 - Added built-in script constant "$NI_CB_TYPE_NOTE".
112 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
113 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
114 - NKSP Language: Added support for user defined script functions.
115 - Implemented built-in script function "change_attack()".
116 - Implemented built-in script function "change_decay()".
117 - Implemented built-in script function "change_release()".
118 - Fixed all change_*() built-in script functions to apply their
119 synthesis parameter changes immediately in case the respective note
120 was triggered at the same time, instead of scheduling the parameter
121 change, especially because it would cause some parameter types's
122 changes either to be ramped (i.e. change_vol()) or other types even
123 to have not effect at all (i.e. change_attack()).
124 - Implemented built-in script function "sh_left()".
125 - Implemented built-in script function "sh_right()".
126 - Implemented built-in script function "min()".
127 - Implemented built-in script function "max()".
128 - NKSP Fix: "init" event handler was not always executed when a script
129 was loaded.
130 - NKSP built-in wait() script function: abort script execution if
131 a negative or zero wait time was passed as argument (since this is
132 a common indication of a bug either of the script or even of the
133 engine, which could lead to RT instability or even worse).
134 - ScriptVM: Implemented automatic suspension of RT safety
135 threatening scripts.
136 - Provide more user friendly error messages on syntax errors.
137 - Fixed NKSP parser warning "Not a statement" when assigning an
138 initializer list to an array variable.
139
140 * Instruments DB:
141 - Fixed memory access bug of general DB access code which lead to
142 undefined behavior.
143
144 Version 2.0.0 (15 July 2015)
145
146 * packaging changes:
147 - fixed building with newer MinGW-w64

182 in order to get rid of warnings from automake 1.14
183
184 * general changes:
185 - Refactoring: moved the independent code from
186 the Gigasampler format engine to base classes
187 - command line option '--profile' is currently disabled, since the
188 respective profiling code is currently broken
189 - Introduced support for optional environment variable
190 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
191 where the sampler shall look for instrument editor plugins
192 (patch by Luis Garrido, slightly modified).
193 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
194 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
195 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
196 note (in this implementation of the sampler its simply hard routed to
197 the 1st effect send of the sampler channel, no matter what the actual
198 effect type is)
199 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
200 note (in this implementation of the sampler its simply hard routed to
201 the 2nd effect send of the sampler channel, no matter what the actual
202 effect type is)
203 - implemented support for internal LADSPA effects
204 - raised limit of program change queue from 100 to 512
205 (as suggested by Alex Stone)
206 - implemented sine LFO, pulse LFO and saw LFO
207 - experimental support for per voice equalization
208 - added command line option --exec-after-init
209 - Introduced new C++ API method:
210 EngineChannel::InstrumentFileName(int index)
211 allowing to retrieve the whole list of files used for the loaded
212 instrument on an engine channel (a.k.a. part). Some GigaStudio
213 instruments for example are splitted over several files like
214 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
215 - Added new C++ API method Sampler::GetGlobalMaxVoices().
216 - Added new C++ API method Sampler::GetGlobalMaxStreams().
217 - Added new C++ API method Sampler::SetGlobalMaxVoices().
218 - Added new C++ API method Sampler::SetGlobalMaxStreams().
219 - Various "const" and "restrict" optimizations.
220 - all engines: add pan CC value to instrument pan parameter before
221 applying panning, instead of using two separate pan functions in
222 series (#182)
223 - added a lock guard class for exception safe mutex handling and
224 used it everywhere appropriate
225 - Immediately apply scale tuning changes to active voices.
226 - Exposed scale tuning to C++ API (along to the already existing standard
227 SysEx way).
228 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
229 and broken for ppc64. (Seq_cst loads and stores are actually not
230 used in LS, so the bug wasn't noticable.)
231 - lsatomic.h: added ARMv7 support
232 - Added support for multiple MIDI input ports per sampler channel (and
233 added various new C++ methods for this new feature / design change, old
234 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
235 as deprecated but are still there and should provide full behavior
236 backward compatibility).
237 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
238 unsafe and caused compilation error with clang 2.x).
239 - Bugfix: only process the latest MIDI program change event.
240 - Introducing the LSCP shell, which provides convenient control of the
241 sampler from the command line by providing LSCP aware features.
242 - VirtualMidiDevice: Added support for program change.
243 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
244 - VirtualMidiDevice: Added support for pitch bend.
245 - Aftertouch: extended API to explicitly handle channel pressure and
246 polyphonic key pressure events (so far polyphonic pressure was not
247 supported at all, and channel pressure was rerouted as CC128 but not
248 used so far).
249 - Added initial support for real-time instrument scripts. The script VM
250 code is shared by all sampler engine implemementations, however only the
251 gig file format currently provides support for storing instrument scripts
252 (as LinuxSampler extension to the original GigaStudio 4 format).
253
254 * Gigasampler format engine:
255 - implemented the "round robin keyboard" dimension
256 - fixed round robin and random dimensions for cases when number of
257 dimension zones is not a power of two
258 - made round robin use a counter for each region instead of each
259 key
260 - bugfix: pitch LFO controller "internal+aftertouch" was broken
261 - bugfix: filter keyboard tracking was broken
262 - filter performance fix (an unnecessary copy was made of the
263 filter parameters in each sub fragment)
264 - handle special case when pan parameter in gig file has max or
265 min value
266 - Exclusive Groups: don't ever stop voices of the same note,
267 doesn't sound naturally with a drumkit
268 - fixed EG1 modulation when attack or release is zero
269 - Fixed support for 'aftertouch' attenuation controller.
270 - Fixed crash that happened with velocity split sounds under certain
271 conditions (see also previous commit on libgig).
272 - fixed behaviour of filter LFO
273
274 * SFZ format engine:
275 - Initial implementation (not usable yet)
276 - added support for v2 multiple stage envelope generators
277 - added a fine-tuned v1 envelope generator instead of using the
278 one from the gig engine

280 - added support for trigger=first, trigger=legato and sw_previous
281 - allow non-numerical key values ("C#4" for example)
282 - "key" opcode now sets pitch_keycenter too
283 - fixed error when unloading instrument with same sample used by
284 multiple regions
285 - added some opcode aliases, like loopmode for loop_mode, to be
286 more compatible
287 - added support for trigger=release and rt_decay
288 - added support for off_mode=normal
289 - added support for random, seq_position, seq_length and volume

294 - fixed crash when using sw_down/up
295 - improved logic for sw_lokey/hikey/up/down/last
296 - added more v1 aliases to parser
297 - reduced memory usage for sfz data
298 - RT-safeness: avoid malloc in audio thread
299 - fixed a bug that could cause voice stealing to fail
300 - optimized sample lookup
301 - improved support for exclusive groups (group, off_by and
302 off_mode)
303 - added support for controller triggered regions (on_locc/on_hicc)
304 - added support for loop_mode=one_shot
305 - fixed playback of 16 bit wav files on big endian CPUs
306 - added support for Ogg Vorbis sample files
307 - use loop markers from sample file if loop_start and loop_end are
308 not set in sfz file
309 - implemeted filters. Filter types: lowpass, bandpass, bandreject

450 - Listen to all interfaces on Mac OS X (INADDR_ANY)
451 - VST bugfix: If the host called resume() before and after
452 changing sample rate or block size, the number of channels was
453 incorrectly set to two. This caused silence in Cubase 5.
454 - save engine type (gig, sfz or sf2) in plugin state

502 the driver will automatically connect to other CoreMIDI clients' ports
503 (e.g. external MIDI devices being attached to the Mac)
504 - added support for MIDI note on velocity filter
505 - CoreMIDI: fixed memory deallocation error
506 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
507 virtual keyboards in frontends / instrument editors being stuck.

629 - Pass/preserve polyphonic variable data from respective "note" event
630 handler to "release" event handler.

637 channel to a different engine type
638 - fixed crash when deleting a sampler channel or changing engine
639 type while an instrument load was in progress
640 - bugfix: playing a note while changing the instrument could cause
641 a crash, or give "Handing back unknown region" error messages
642 - bugfix: calling SET VOICES (which Fantasia does on start and
643 refresh) could cause instruments to be unloaded
644 - Mac OS X: fixed name collision of enum in EffectControl and
645 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
646 - Mac OS X: fixed hanging threads
647 - Windows: disabled the previous thread fix on non-Mac systems, as
648 it caused hanging threads on Windows
649 - Fixed possible crashes due to corrupted MIDI/audio device list
650 after MIDI/audio device creation failure
651 - When creating MIDI instrument map entries with "PERSISTENT" type, the
652 instruments were uselessly precached with zero samples, however it still
653 took the full preloading time and on 1st program change the respective
654 instrument was completely reloaded again.

656 sent to the same sampler channel (patch from the Open Octave
657 project, slightly adjusted)

672 playing a note in a key group
673 - fixed erroneous error message piping in VoiceBase.h
674 (labelled "Disk stream not available in time")
675 - Update effects on sample rate & period size changes (to avoid
676 crashes and noise on such transitions).
677 - ignore missing LADSPA paths without ignoring valid LADSPA paths
678 (fixes #208)
679 - Fixed bug in LSCP grammar definition which caused a statement like
680 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
681 practically irrelevant, however it caused problems with the new LSCP
682 shell's auto completion feature).
683 - Fixed MIDI program change messages being ignored if quickly executed
684 after each other (fixes #231).
685
686 Version 1.0.0 (31 July 2009)
687
688 * packaging changes:
689 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

699 - minor fix in configure for mmsystem.h detection on MinGW
700 - Windows: look for editor plugins and Fantasia using base
701 directory of liblinuxsampler dll (look in the same directory and one
702 directory above)
703 - configure script fix: removed unconditional use of SSE
704 - fixed building with sqlite installed in a non-standard directory
705 - when cross-compiling, don't try to create instruments.db
706 - fix for new mingw-w64 version, which has usleep
707
708 * general changes:
709 - bugfix: on some POSIX systems instrument editor plugins refused to
710 load as we used a non-portable Linux specific struct field
711 (fixes bug #70, patch by Ronald Baljeu)
712 - fixed endless loop which occured when loading an instrument editor
713 plugin DLL on Windows systems failed
714 - fixed memory leaks that occurred when liblinuxsampler was unloaded
715 - optimized the SynchronizedConfig class so it doesn't wait
716 unnecessarily long after an update
717 - added support for notifying instrument editors on note-on / note-off
718 events (e.g. to highlight the pressed keys on the virtual keyboard
719 of gigedit)
720 - added support for triggering notes by instrument editors (see above)
721 - be verbose on DLL load errors (on Linux)
722 - fixed di-harmonic triangle LFO implementation (this LFO implementation
723 is only used by very few systems, most pick the int math
724 implementation, which is usually faster)
725 - fixes for audio drivers with varying buffer sizes
726 - experimental support for running LinuxSampler as a DSSI, LV2 and
727 VST plugin
728 - notification events for stream/voice count statistics are now sent
729 only when there are actual changes

731 multi-core and multi-cpu systems
732 - maximum voices and disk streams can now be altered at runtime
733 - fixed CPU feature detection on x86_64 (maybe fixes #108)
734 - automatic stacktrace mechanism is now turned off by default and can
735 be switched on by command line option "--stacktrace" (the automatic
736 stacktrace mechanism seems to be broken on most systems at the moment)
737 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
738 a pointer to the launched InstrumentEditor object
739 - added optional 3rd party user data parameter for following
740 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
741 InstrumentEditor::Launch(),
742 InstrumentManager::LaunchInstrumentEditor()
743 - theoretical fix: made SynchronizedConfig follow C++0x memory
744 model more strictly
745 - fixes for using large audio device buffers
746 - Windows: add the installation directory to the DLL search path
747 when loading an editor plugin (solves problems with VST and
748 gigedit on systems with other GTK versions installed)
749 - updated linuxsampler man page
750
751 * audio driver:
752 - removed the nonsense audio channel constraint (which was hard coded to
753 max. 100 audio channels) for most audio drivers
754 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
755 opposed to the LSCP specs
756 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
757 reflected the wrong value
758 - fixed a memory management bug in ASIO driver
759 - Makefile fix: JACK_CFLAGS wasn't used
760 - JACK: use jack_client_open instead of the deprecated
761 jack_client_new

767 win64)
768 - VST: added support for sample rate and buffer size changes
769 - VST: close editor (Fantasia) when the VST is removed
770 - VST: avoid opening Fantasia more than once for each VST instance
771 - VST: export main function as "main" on Linux too (fix for
772 energyXT)
773 - VST: changed number of output channels from one stereo to 16
774 stereo
775 - added channel routing, fxsends and midi maps to the settings
776 stored in the plugin state
777 - performance optimization of AudioChannel::MixTo() and
778 AudioChannel::CopyTo() methods using GCC vector exensions
779 (if available)
780 - ASIO fixes: avoid initializing the device twice, avoid throwing
781 exception when getting parameters from a disconnected device
782
783 * MIDI driver:
784 - added JACK MIDI driver
785 - dispatch bank select as ordinary CC as well, the user might seriously
786 want to (mis)use it for some purpose ("fixed" in all current MIDI
787 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
788 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
789 CoreMidi or AU
790 - fixed mingw-w64 compilation error in MME driver
791 - made program change handling in MIDI thread real-time safe by
792 moving the logic to a non-RT thread
793 - fixed minor memory leak in ALSA driver
794
795 * instruments database:
796 - avoid time consuming samples scanning when adding instruments
797 to the instruments database

802 - work-around for missing fnmatch function on Windows to make
803 instrument database compilable
804 - added instrument database support on Windows
805 works with both standalone mode and VST plugin.
806 the instruments DB file is located in
807 %USERPROFILE%\.linuxsampler\instruments.db which allows different
808 databases for each windows user
809 if no DB is present it automatically creates the .linuxsampler subdir
810 and then creates an empty DB
811 - fixed recursive import, which was broken on Windows
812
813 * Gigasampler format engine:
814 - fixed a memory leak that could happen when a channel was deleted
815 while notes were playing
816 - made it possible to load an instrument even if the audio thread
817 isn't running
818 - added partial support for the "Controller Triggered" MIDI rule,
819 enough for piano gigs with pedal noise samples
820 - minor fix: only mark FX sends as being modified if really the
821 respective FX send MIDI controller was used
822 - added support for GM global device volume SysEx message
823 (can be selected at compile time to either apply globally to the
824 whole sampler [default] or only to the sampler channels that are
825 connected to the respective MIDI input port the SysEx message arrived
826 on)
827 - bugfix: notes triggered at position 0 in the audio buffer were
828 sometimes wrongly killed in the same buffer, causing no sound to
829 be played
830 - added support for chromatic / drumkit mode Roland GS Sysex message
831 which is usally used to switch a part between chromatic sounds and
832 drumkit sounds (as opposed to their common default setting of MIDI
833 part 10 being a drumkit part and all other ones chromatic parts), in
834 LS however one can switch between the first 16 MIDI instrument maps
835 defined for the sampler
836 - made it possible to create multiple sample channels even if the
837 audio thread isn't running
838 - fixed crash when removing channel with active voices (#116)
839 - bugfix: on sample reference changes (instrument editor), only
840 un-cache the respective sample if it's really not used by any
841 sampler engine anymore
842 - re-cache samples in case they were changed by an instrument editor,
843 e.g. when a sample was added while playing (#82)
844 - fixed hanging notes which occured when note-off event had the exact
845 same time stamp as the voice's note-on event and occured both in the
846 same audio fragment cycle (fixes bug #112)
847 - added support for the "fine tune" and "pitch bend range"
848 instrument-level gig parameters
849 - fixed minor artifacts in pitch bend handling
850 - added support for GS Reset SysEx message
851 - allow gig files to use unlimited downward pitch shifting
852 - added a limit check for upward pitch shifting
853 - bugfix: sometimes, when playing a note twice fast, the second
854 note was silent
855 - fixed crash happening when a pitch bend event arrived at the
856 same time a new instrument was loading
857
858 * LSCP server:
859 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
860 react on MIDI data arriving on certain sampler channels (so far only
861 Note-On and Note-Off events are sent via this LSCP event)
862 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
863 react on MIDI data arriving on certain MIDI input devices (so far only
864 Note-On and Note-Off events are sent via this LSCP event)
865 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
866 SET DB_INSTRUMENT FILE_PATH
867 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
868 frontends to send MIDI messages to specific sampler channel
869 - added two additional fields to GET FILE INSTRUMENT INFO command -
870 KEY_BINDINGS and KEYSWITCH_BINDINGS
871 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
872 was incorrect
873 - Optimized the retrieval of the MIDI instrument mappings
874 - added new LSCP command "SET VOICES" to globally alter the maximum
875 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
876 be triggered respectively
877 - added new LSCP command "SET STREAMS" to globally alter the maximum
878 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
879 which will be triggered respectively
880 - bugfix: retry if "select" returns EINTR (this fixes a crash when
881 a gigedit file dialog is opened)
882 - close all connections when LSCPServer is deleted
883 - hard close of all sockets on exit
884 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
885 driver
886
887 * Bug fixes:
888 - fixed a crash which occurs when removing a sampler channel waiting
889 to start instrument loading after another channel
890 - fixed a crash which occurs when removing a sampler channel with
891 instrument loading in progress (bug #113)
892 - fixed termination caused by uncaught exception when adding MIDI
893 instrument with PERSISTENT load mode
894 - fixed possible iterator invalidations when resetting the sampler
895 - fixed memory leaks when issuing the following LSCP commands:
896 GET AUDIO_OUTPUT_DRIVER INFO
897 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
898 GET MIDI_INPUT_DRIVER INFO
899 GET MIDI_INPUT_DRIVER_PARAMETER INFO
900 - fixed possible compilation error when sqlite is not present
901 - fixed orphaned pointers when setting maximum voices limit (bug #118)
902 - fixed crash when changing the audio output device of a sampler
903 channel with loaded instrument and start playing notes
904 - fixed endless loop in Engine::SuspendAll() (bug #120)
905 - fixed a low-level atomic load function that was broken on 64-bit
906 PowerPC, which probably could cause crashes on that platform
907 - fixed a memory management error which could cause a crash when a
908 plugin was unloaded
909 - bugfix: two private structs had the same name, which could cause
910 problems if the linker chose the wrong constructor
911 - fixed low-level ConditionServer usage bug that caused lockups on
912 Windows
913
914
915 Version 0.5.1 (6 December 2007)
916
917 * packaging changes:
918 - added autoconf checks for pthread library
919 - added autoconf check for pthread bug found on certain NPTL-enabled
920 glibc versions (see Gentoo bug report #194076)
921 - added autoconf checks for MS Windows
922
923 * general changes:
924 - bugfix: the thread used by an editor plugin didn't die when the
925 editor closed
926 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
927 out all the space. operator--() did not apply size_mask after
928 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
929 order to avoid problems with the _NonVolatileReader functions.
930 - bugfix: Stream.h: added a missing divide by BytesPerSample in
931 GetWriteSpace(). Since this function is currently only used in
932 the stream's qsort() compare function, it didn't trigger any
933 bugs.
934 - Resampler.h, Synthesizer.h: cubic interpolation now works in
935 24bit mode too. Faster method to read 24bit words on little
936 endian machines (x86): replaced 3 byte reads + shifts with a 1
937 unaligned 32bit read and shift
938 - experimental support for MS Windows (MIDI input via MME, AUDIO
939 output via ASIO)
940 - made handling of SIGINT signal (Ctrl-C) a bit more robust
941 - support for monitoring the total number of active disk streams
942 (new LSCP commands: GET TOTAL_STREAM_COUNT,
943 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
944
945 * AUDIO driver:
946 - added Windows ASIO low latency audio driver
947
948 * MIDI driver:
949 - added MME Windows MIDI driver
950
951 * LSCP server:
952 - added support for Windows style path / filenames, however with
953 forward slash path separators instead of backslash
954 (i.e. "C:/foo/bar.gig")
955 - allow naughty liblscp to send non-string device parameters within
956 apostrophes as well
957 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
958 "LIST FILE INSTRUMENTS <file>" and
959 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
960 about an arbitrary instrument file on the system where the sampler is
961 running on
962
963 Version 0.5.0 (15 October 2007)
964
965 * packaging changes:
966 - config.h is not going to be installed along with liblinuxsampler's
967 API header files anymore
968 - only the API relevant header (and source) files will be exported to
969 the Doxygen API documentation (explicitly listed in Doxyfile.in)
970 - added completely new XCode project files for Mac OSX which is now
971 capable to execute our autoconf environment, thus no need anymore
972 to maintain the compile time configuration file (osx/version.h) for
973 OSX manually (patch by Toshi Nagata)
974 - fixed buggy boolean --enable-foo / --disable-foo configure script
975 parameters
976 - global.h now only covers global definitions that are needed for the
977 C++ API header files, all implementation internal global definitions
978 are now in global_private.h
979 - atomic.h is not exposed to the C++ API anymore
980 - no need to include config.h anymore for using LS's API header files
981 - fixed warnings in API doc generation
982
983 * general changes:
984 - replaced the old, confusing MIDI program change mechanism by a
985 flexible MIDI instrument mapper which allows to map arbitrary
986 (MIDI bank, MIDI program) pairs with arbitrary
987 (engine type, instrument file, file index) triplets which will be
988 loaded on the respective channel when such MIDI program change
989 messages arrive, beside that, each entry allows to define a life-time
990 strategy for the instrument, so the user can define whether the
991 instrument should i.e. be permanently loaded (to be able to switch
992 quickly among sounds) or i.e. loaded just on demand when the
993 respective program change arrives (to safe RAM space), as well as a
994 global volume factor for each entry, so the user can adjust the volume
995 dynamic of his mapped instrument collection without having to modify
996 the instrument files, also one can manage arbitrary amount of such
997 MIDI instrument maps and assign each sampler channel individually
998 a certain map, so that i.e. separation of normal instruments and
999 drumkits is possible
1000 - new notification events for tracking changes to audio/MIDI devices,
1001 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1002 - sampler was limited to load max. 200 instruments in the background
1003 due to a constant size RingBuffer FIFO which is now replaced by a
1004 dynamic (unlimited) size std::list FIFO
1005 - added FX sends, these allow to route audio signals to arbitrary audio
1006 output channels for being processed by external effect processors
1007 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1008 controllers
1009 - global (sampler wide) volume can now be controlled at runtime
1010 - Implemented new, improved notification system
1011 - fixed compilation errors regarding OSX
1012 (patch by Toshi Nagata)
1013 - implemented instruments database
1014 - added support for escape sequences to the instruments database
1015 - added highly experimental support for on-the-fly instrument editing
1016 within the sampler's process (by using instrument editor plugins),
1017 you'll notice the new "Registered instrument editors:" message on
1018 startup, added a new LSCP command:
1019 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1020 to spawn a matching instrument editor for the instrument on the
1021 given sampler channel, the plugin path can be overridden at compile
1022 time with ./configure --enable-plugin-dir=/some/dir
1023 - added experimental code for synchronizing instrument editors hosted
1024 in the sampler's process to safely edit instruments while playing
1025 without a crash (hopefully) by either suspending single regions
1026 wherever possible or if unavoidable whole engine(s)
1027 - fixed several issues in fundamental "Thread" class: set scheduling
1028 policy and priority on thread level, set a minimum stack size for
1029 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1030 threads simply inherited properties of starting thread instead of
1031 setting their own policy and priority
1032 - minor fix in our automatic stack trace mechanism on crashes, the
1033 main process did not wait for the stack trace process to finish
1034 its output
1035 - fixed some minor memory leaks
1036 - reenabled assembly features support, at the moment only for
1037 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1038 - minor assembly fix in x86 features detection (don't use the PIC
1039 register, to avoid relocations in the text segment at runtime)
1040 - POSIX callback functions of Thread.h are hidden
1041
1042 * MIDI driver:
1043 - dispatch bank select (MSB and LSB) messages
1044
1045 * audio driver:
1046 - the ALSA audio output driver parameters now reflect the correct
1047 parameter value ranges for the respective selected sound card
1048 (patch by Till Wimmer, a bit fixed and extended)
1049
1050 * Gigasampler format engine:
1051 - if a filter is used and EG2 finishes before EG1, let the voice
1052 die when EG2 has finished (this fixes a problem with clicks and
1053 voice starvation for some gigs)
1054 - playback is no longer disabled during instrument loading
1055 - all notes playing on a channel that changes its instrument keep
1056 playing with the old instrument until they get a note off
1057 command
1058 - EG fix: a release value of zero could cause noises or crash
1059 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1060 - EG fine tuning: when attack is zero the EG starts at a level
1061 above max sustain level, which means that there is a decay phase
1062 even if sustain is 100%
1063 - more EG fixes: the level could sometimes go below zero and cause
1064 noises or crashes
1065 - minor fix of EGDecay (patch by Toshi Nagata)
1066 - fixed compiler error when --enable-override-filter-type was
1067 supplied to the configure script (fixes #46)
1068 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1069 instead of a fix value
1070 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1071 127 (solo mode) only kill voices if the respective mode really
1072 changed
1073
1074 * LSCP server:
1075 - fixed compile time error for old Bison versions
1076 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1077 - parser now supports extended ASCII character set
1078 (up to ASCII code 255, i.e. includes now umlauts and accents)
1079 - filename arguments in LSCP commands now allow to use escape
1080 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1081 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1082 code value like \xf2) (fixes bug #24)
1083 - the following LSCP commands now also support escape sequences for at
1084 least one of their text-based parameters (i.e. name, description):
1085 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1086 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1087 "SET DB_INSTRUMENT_DIRECTORY NAME",
1088 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1089 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1090 "FIND DB_INSTRUMENT_DIRECTORIES"
1091 - returns verbose syntax errors (line and column where syntax error
1092 occured, the unexpected character and the actually expected, possible
1093 character(s), the latter only if less than 5 possibilities)
1094 - made sure that LSCP syntax is not affected by gigedit locale
1095 settings
1096 - bugfix regarding strings parameter lists: all comma separated lists
1097 of strings were treated as being one string containing commas
1098 (fixes #57)
1099
1100 * Bug fixes:
1101 - fixed crash occurring on certain LSCP scripts (Bug 39)
1102 - another thread safety fix for lscp "load engine" and "set
1103 channel audio output device"
1104 - fixed a crash which occurs when reassigning the same engine
1105 on a sampler channel with connected MIDI device
1106 - fixed a crash which occurs when changing the number of ports of a MIDI
1107 device connected to a sampler channel to number less then or equal
1108 to the index of the port to which the sampler channel is connected.
1109 - The previous bindings were not been disconnected when altering
1110 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1111 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1112 - The active stream/voice count statistic was incorrect.
1113 - notification events were not been sent for some sampler
1114 channel changes
1115 - added default min and max values to restrict the number of allowed
1116 audio output channels and MIDI input ports
1117 - the connection to the PCM interface is now closed when destroying
1118 an audio output device
1119 - files with slash in their path or filename could not be loaded
1120
1121 * test cases:
1122 - updated and fixed (haven't been touched in a while)
1123
1124 Version 0.4.0 (24 November 2006)
1125
1126 * packaging changes:
1127 - changed deprecated copyright attribute to license; added ldconfig
1128 to post-(un)install steps; added devel package for liblinuxsampler;
1129 to linuxsampler.spec (RPM)
1130 - install necessary development header files for allowing 3rd party
1131 applications to link against liblinuxsampler
1132 - liblinuxsampler's API documentation can be generated with 'make docs'
1133 (Doxygen required)
1134 - added benchmark to automatically detect the best triangle LFO
1135 implementation (currently either an integer math solution or a
1136 di-harmonic approximation), automatic detection can be overriden
1137 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1138 configure script argument though (mandatory for cross-compilation)
1139 - do not automatically pick optimized gcc flags if the user already
1140 provided some on his own (as CXXFLAGS)
1141 - added compile time option to disable processing of All-Notes-Off MIDI
1142 messages
1143 - added compile time options to allow disabling the various audio and
1144 MIDI drivers
1145 - fixed automatic GCC CPU switch detection on PPC
1146 (patch by Ebrahim Mayat)
1147
1148 * Gigasampler format engine:
1149 - extensive synthesis optimization
1150 (reimplementation of EGs and LFO(s), removed synthesis parameter
1151 prerendering and the synthesis parameter matrix in general, splitting
1152 each audio fragment into subfragments now where each subfragment uses
1153 constant pitch and filter coefficients. The volume coefficient is
1154 linearly interpolated inside a subfragment, unless
1155 --disable-interpolate-volume is set.)
1156 - fine tuning of the EG modulation parameters
1157 - improved filter cutoff calculation by adding support for the
1158 following gig parameters: Cutoff freq (used when no cutoff
1159 controller is defined), Control invert, Minimum cutoff, Velocity
1160 curve and Velocity range. The keyboard tracking now scales
1161 cutoff frequency instead of resonance.
1162 - added support for gig parameter Resonance.
1163 - fixed bug in sysex handling (patch by Juan Linietsky)
1164 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1165 which can be overridden with --enable-global-attenuation
1166 - EG fixes: made the length of "attack hold" stage more
1167 accurate. Release stage can now start before attack stage
1168 ends. Cancel release didn't work when sustain was zero. Attack
1169 time now has a minimal value to prevent clicks.
1170 - fixed pitch changes larger than one octave
1171 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1172 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1173 all modes can be altered via standard GM messages, that is CC5 for
1174 altering portamento time, CC65 for enabling / disabling portamento
1175 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1176 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1177 parameter) and crossfade
1178 - added support for the "attenuation controller threshold" gig
1179 parameter
1180 - added smoothing of volume changes caused by control change
1181 messages
1182 - sample loop parameters are now taken from the DimensionRegion
1183 instead of the wave chunk
1184 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1185 not equal to a power of two
1186 - reimplementation of the filter algorithm. The new filter is more
1187 accurate and supports all gig filter types, including bandreject
1188 and lowpass turbo.
1189 - real support for 24 bit samples - samples are not truncated to
1190 16 bits anymore
1191 - support for aftertouch (channel pressure, not polyphonic
1192 aftertouch)
1193 - LFO1 behaviour fixed (dampening from max volume instead of
1194 amplifying from 0)
1195
1196 * LSCP server:
1197 - fixed application exit on broken pipe error (fixes bug #20)
1198 - fixed the notification messages delay due to lack of
1199 network activity (fixes bug #26)
1200 - fixed parser bug which occured on space(s) within device parameters
1201 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1202
1203 * audio driver:
1204 - added aRts audio output driver (by no means RT safe)
1205
1206 * MIDI driver:
1207 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1208 messages several times instead of once
1209 - API extension for MIDI drivers which already supply exact time stamps
1210 for events (i.e. for offline rendering based MIDI drivers)
1211 - added checks for bad MIDI data
1212
1213 * linuxsampler application:
1214 - show available sampler engine types on startup
1215
1216 * general changes:
1217 - support for muting sampler channels and solo mode of the same, two new
1218 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1219 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1220 introduced for this, the behavior is the same like on a mixer console
1221 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1222 --enable-process-muted-channels which can be used to enable the
1223 processing of muted channels.
1224 - support for sostenuto pedal
1225 - support for monitoring the total number of active voices
1226 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1227 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1228 - fixed some memory management errors
1229 - fixed some concurrency problems that could lead to crashes when
1230 LSCP commands were executed
1231 - fixed crash when instrument loading failed previously on the same
1232 sampler channel (fixes bug #36)
1233
1234 Version 0.3.3 (15 July 2005)
1235
1236 * packaging changes:
1237 - fixed compilation with gcc 4.0
1238
1239 * Gigasampler format engine:
1240 - LFO preprocessing was performed even though the respective LFO was
1241 disabled by the instrument patch (minor efficiency fix)
1242 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1243 for volume ramp downs in the same fragment (needed for current voice
1244 stealing implementation) then simply inform the user with a warning
1245 about possible click sounds and reduce the volume ramp down
1246 appropriately instead of cancelling the audio device connection
1247
1248 Version 0.3.2 (24 June 2005)
1249
1250 * packaging changes:
1251 - updated autotools build files to compile on OS X
1252 (conditional compilation of CoreMIDI and MidiShare drivers)
1253 - hand-crafted assembly optimization code can be disabled with
1254 './configure --disable-asm' (definitely not recommended)
1255 - fixed 'make dist' rule to include all necessary files
1256 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1257 (due to 'dist-bzip2' automake option)
1258
1259 * Gigasampler format engine:
1260 - support for the gig parameters for "release velocity response" curves
1261 - fine tuning of the EGADSR envelope
1262 - volume of release triggered samples now depends on note-on velocity,
1263 note length and gig parameter "release trigger decay" instead of
1264 note-off velocity.
1265 - revised voice stealing
1266 (fixes crash and endless loop caused by voice stealing)
1267 - don't reset scale tuning on instrument or audio output device change
1268 - handle key group conflicts right at the beginning of each fragment
1269 instead of when the respective voice is actually launched
1270 (fixes undefined behavior if stolen voices belonged to a key group -
1271 this case was followed by a "killed voice survived" error message)
1272 - fixed minor issue with null/silence samples
1273 (those stole voices even though they don't need a voice at all which
1274 resulted in "voice stealing didn't work out" messages)
1275 - don't reset volume, pan, pitch and MIDI controller values on
1276 instrument or audio output device change
1277
1278 * LSCP server:
1279 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1280 - fixed LSCP event "CHANNEL_INFO" notification
1281 (e.g. did not notify on volume changes or MIDI program change events)
1282
1283 * linuxsampler application:
1284 - added command line parameters --lscp-addr and --lscp-port to override
1285 default IP address and port of LSCP server
1286
1287 Version 0.3.1 (24 May 2005)
1288
1289 * initial release
