Wed May 24 20:05:38 2017 UTC (6 years, 10 months ago) by schoenebeck
File size: 71132 byte(s)
* Fixed invalid (note-on) event ID being assigned to new Note
  objects.
* Fixed a bunch of scheduler time related bugs.
* Bumped version (2.0.0.svn47).

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

146 - Implemented built-in script function "in_range()".
147 - Implemented built-in script function "change_amp_lfo_depth()".
148 - Implemented built-in script function "change_amp_lfo_freq()".
149 - Implemented built-in script function "change_pitch_lfo_depth()".
150 - Implemented built-in script function "change_pitch_lfo_freq()".
151 - Implemented built-in script function "change_vol_time()".
152 - Implemented built-in script function "change_tune_time()".
153 - Implemented built-in script function "fade_in()".
154 - Implemented built-in script function "fade_out()".
155 - Fixed acceptance of wrong data type of parameters passed to built-in
156 script functions "change_vol()", "change_tune()", "change_pan()",
157 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
158 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
159 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
160 - Added built-in script function "get_event_par()" and implemented some
161 of its possible parameter selections.
162 - Added built-in script function "set_event_par()" and implemented some
163 of its possible parameter selections.
164 - Fixed a bunch of scheduler time related bugs.
165
166 * Instruments DB:
167 - Fixed memory access bug of general DB access code which lead to
168 undefined behavior.
169 - Cleanup of instruments DB file creation and opening code.
170 - The instrument DB path of linuxsampler's --create-instruments-db argument
171 is now optional, if it is missing, then a default location is used.
172 - Added support for scanning SFZ (.sfz) files.
173 - Added support for scanning Sound Font (.sf2) files.
174 - Fixed undefined DB transaction behavior.

198 - fixed linkage error when building with
199 LDFLAGS="-Wl,--no-undefined" (#190)
200 - fixed compilation with Clang 3.2
201 - removed usage of deprecated Automake variable INCLUDES
202 - fixed building with C++11

212 - enabled automake 'subdir-objects' option and moved external
213 source references (vst, au, asio) from makefiles to cpp files,
214 in order to get rid of warnings from automake 1.14
215
216 * general changes:
217 - Refactoring: moved the independent code from
218 the Gigasampler format engine to base classes
219 - command line option '--profile' is currently disabled, since the
220 respective profiling code is currently broken
221 - Introduced support for optional environment variable
222 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
223 where the sampler shall look for instrument editor plugins
224 (patch by Luis Garrido, slightly modified).
225 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
226 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
227 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
228 note (in this implementation of the sampler its simply hard routed to
229 the 1st effect send of the sampler channel, no matter what the actual
230 effect type is)
231 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
232 note (in this implementation of the sampler its simply hard routed to
233 the 2nd effect send of the sampler channel, no matter what the actual
234 effect type is)
235 - implemented support for internal LADSPA effects
236 - raised limit of program change queue from 100 to 512
237 (as suggested by Alex Stone)
238 - implemented sine LFO, pulse LFO and saw LFO
239 - experimental support for per voice equalization
240 - added command line option --exec-after-init
241 - Introduced new C++ API method:
242 EngineChannel::InstrumentFileName(int index)
243 allowing to retrieve the whole list of files used for the loaded
244 instrument on an engine channel (a.k.a. part). Some GigaStudio
245 instruments for example are splitted over several files like
246 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
247 - Added new C++ API method Sampler::GetGlobalMaxVoices().
248 - Added new C++ API method Sampler::GetGlobalMaxStreams().
249 - Added new C++ API method Sampler::SetGlobalMaxVoices().
250 - Added new C++ API method Sampler::SetGlobalMaxStreams().
251 - Various "const" and "restrict" optimizations.
252 - all engines: add pan CC value to instrument pan parameter before
253 applying panning, instead of using two separate pan functions in
254 series (#182)
255 - added a lock guard class for exception safe mutex handling and
256 used it everywhere appropriate
257 - Immediately apply scale tuning changes to active voices.
258 - Exposed scale tuning to C++ API (along to the already existing standard
259 SysEx way).
260 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
261 and broken for ppc64. (Seq_cst loads and stores are actually not
262 used in LS, so the bug wasn't noticable.)
263 - lsatomic.h: added ARMv7 support
264 - Added support for multiple MIDI input ports per sampler channel (and
265 added various new C++ methods for this new feature / design change, old
266 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
267 as deprecated but are still there and should provide full behavior
268 backward compatibility).
269 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
270 unsafe and caused compilation error with clang 2.x).
271 - Bugfix: only process the latest MIDI program change event.
272 - Introducing the LSCP shell, which provides convenient control of the
273 sampler from the command line by providing LSCP aware features.
274 - VirtualMidiDevice: Added support for program change.
275 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
276 - VirtualMidiDevice: Added support for pitch bend.
277 - Aftertouch: extended API to explicitly handle channel pressure and
278 polyphonic key pressure events (so far polyphonic pressure was not
279 supported at all, and channel pressure was rerouted as CC128 but not
280 used so far).
281 - Added initial support for real-time instrument scripts. The script VM
282 code is shared by all sampler engine implemementations, however only the
283 gig file format currently provides support for storing instrument scripts
284 (as LinuxSampler extension to the original GigaStudio 4 format).
285
286 * Gigasampler format engine:
287 - implemented the "round robin keyboard" dimension
288 - fixed round robin and random dimensions for cases when number of
289 dimension zones is not a power of two
290 - made round robin use a counter for each region instead of each
291 key
292 - bugfix: pitch LFO controller "internal+aftertouch" was broken
293 - bugfix: filter keyboard tracking was broken
294 - filter performance fix (an unnecessary copy was made of the
295 filter parameters in each sub fragment)
296 - handle special case when pan parameter in gig file has max or
297 min value
298 - Exclusive Groups: don't ever stop voices of the same note,
299 doesn't sound naturally with a drumkit
300 - fixed EG1 modulation when attack or release is zero
301 - Fixed support for 'aftertouch' attenuation controller.
302 - Fixed crash that happened with velocity split sounds under certain
303 conditions (see also previous commit on libgig).
304 - fixed behaviour of filter LFO
305
306 * SFZ format engine:
307 - Initial implementation (not usable yet)
308 - added support for v2 multiple stage envelope generators
309 - added a fine-tuned v1 envelope generator instead of using the
310 one from the gig engine
311 - fixed memory leak and memory handling errors
312 - added support for trigger=first, trigger=legato and sw_previous
313 - allow non-numerical key values ("C#4" for example)
314 - "key" opcode now sets pitch_keycenter too
315 - fixed error when unloading instrument with same sample used by
316 multiple regions
317 - added some opcode aliases, like loopmode for loop_mode, to be
318 more compatible
319 - added support for trigger=release and rt_decay
320 - added support for off_mode=normal
321 - added support for random, seq_position, seq_length and volume

327 - improved logic for sw_lokey/hikey/up/down/last
328 - added more v1 aliases to parser
329 - reduced memory usage for sfz data
330 - RT-safeness: avoid malloc in audio thread
331 - fixed a bug that could cause voice stealing to fail
332 - optimized sample lookup
333 - improved support for exclusive groups (group, off_by and
334 off_mode)
335 - added support for controller triggered regions (on_locc/on_hicc)
336 - added support for loop_mode=one_shot
337 - fixed playback of 16 bit wav files on big endian CPUs
338 - added support for Ogg Vorbis sample files
339 - use loop markers from sample file if loop_start and loop_end are
340 not set in sfz file
341 - implemeted filters. Filter types: lowpass, bandpass, bandreject
342 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
343 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
344 cutoff_cc, cutoff_chanaft.
345 - bugfix: zero ampeg_sustain didn't work
346 - added support for velocity effect on amplifier envelope time
347 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and

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

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

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

669 channel to a different engine type
670 - fixed crash when deleting a sampler channel or changing engine
671 type while an instrument load was in progress
672 - bugfix: playing a note while changing the instrument could cause
673 a crash, or give "Handing back unknown region" error messages
674 - bugfix: calling SET VOICES (which Fantasia does on start and
675 refresh) could cause instruments to be unloaded
676 - Mac OS X: fixed name collision of enum in EffectControl and
677 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
678 - Mac OS X: fixed hanging threads
679 - Windows: disabled the previous thread fix on non-Mac systems, as
680 it caused hanging threads on Windows
681 - Fixed possible crashes due to corrupted MIDI/audio device list
682 after MIDI/audio device creation failure
683 - When creating MIDI instrument map entries with "PERSISTENT" type, the
684 instruments were uselessly precached with zero samples, however it still
685 took the full preloading time and on 1st program change the respective
686 instrument was completely reloaded again.
687 - fixed handling of rapid bank select and program change messages
688 sent to the same sampler channel (patch from the Open Octave
689 project, slightly adjusted)

704 playing a note in a key group
705 - fixed erroneous error message piping in VoiceBase.h
706 (labelled "Disk stream not available in time")
707 - Update effects on sample rate & period size changes (to avoid
708 crashes and noise on such transitions).
709 - ignore missing LADSPA paths without ignoring valid LADSPA paths
710 (fixes #208)
711 - Fixed bug in LSCP grammar definition which caused a statement like
712 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
713 practically irrelevant, however it caused problems with the new LSCP
714 shell's auto completion feature).
715 - Fixed MIDI program change messages being ignored if quickly executed
716 after each other (fixes #231).
717
718 Version 1.0.0 (31 July 2009)
719
720 * packaging changes:
721 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
722 causing e.g. the libgig test to fail when
723 "./configure --disable-jack-driver" was used
724 (patch by Alexis Ballier)
725 - fixed compilation with gcc 4.3
726 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

731 - minor fix in configure for mmsystem.h detection on MinGW
732 - Windows: look for editor plugins and Fantasia using base
733 directory of liblinuxsampler dll (look in the same directory and one
734 directory above)
735 - configure script fix: removed unconditional use of SSE
736 - fixed building with sqlite installed in a non-standard directory
737 - when cross-compiling, don't try to create instruments.db
738 - fix for new mingw-w64 version, which has usleep
739
740 * general changes:
741 - bugfix: on some POSIX systems instrument editor plugins refused to
742 load as we used a non-portable Linux specific struct field
743 (fixes bug #70, patch by Ronald Baljeu)
744 - fixed endless loop which occured when loading an instrument editor
745 plugin DLL on Windows systems failed
746 - fixed memory leaks that occurred when liblinuxsampler was unloaded
747 - optimized the SynchronizedConfig class so it doesn't wait
748 unnecessarily long after an update
749 - added support for notifying instrument editors on note-on / note-off
750 events (e.g. to highlight the pressed keys on the virtual keyboard
751 of gigedit)
752 - added support for triggering notes by instrument editors (see above)
753 - be verbose on DLL load errors (on Linux)
754 - fixed di-harmonic triangle LFO implementation (this LFO implementation
755 is only used by very few systems, most pick the int math
756 implementation, which is usually faster)
757 - fixes for audio drivers with varying buffer sizes
758 - experimental support for running LinuxSampler as a DSSI, LV2 and
759 VST plugin
760 - notification events for stream/voice count statistics are now sent
761 only when there are actual changes
762 - added memory ordering constraints to improve stability on
763 multi-core and multi-cpu systems
764 - maximum voices and disk streams can now be altered at runtime
765 - fixed CPU feature detection on x86_64 (maybe fixes #108)
766 - automatic stacktrace mechanism is now turned off by default and can
767 be switched on by command line option "--stacktrace" (the automatic
768 stacktrace mechanism seems to be broken on most systems at the moment)
769 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
770 a pointer to the launched InstrumentEditor object
771 - added optional 3rd party user data parameter for following
772 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
773 InstrumentEditor::Launch(),
774 InstrumentManager::LaunchInstrumentEditor()
775 - theoretical fix: made SynchronizedConfig follow C++0x memory
776 model more strictly
777 - fixes for using large audio device buffers
778 - Windows: add the installation directory to the DLL search path
779 when loading an editor plugin (solves problems with VST and
780 gigedit on systems with other GTK versions installed)
781 - updated linuxsampler man page
782
783 * audio driver:
784 - removed the nonsense audio channel constraint (which was hard coded to
785 max. 100 audio channels) for most audio drivers
786 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
787 opposed to the LSCP specs
788 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
789 reflected the wrong value
790 - fixed a memory management bug in ASIO driver
791 - Makefile fix: JACK_CFLAGS wasn't used
792 - JACK: use jack_client_open instead of the deprecated
793 jack_client_new

796 previous binary release but accidentally never committed to CVS
797 (fixes #117)
798 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
799 win64)
800 - VST: added support for sample rate and buffer size changes
801 - VST: close editor (Fantasia) when the VST is removed
802 - VST: avoid opening Fantasia more than once for each VST instance
803 - VST: export main function as "main" on Linux too (fix for
804 energyXT)
805 - VST: changed number of output channels from one stereo to 16
806 stereo
807 - added channel routing, fxsends and midi maps to the settings
808 stored in the plugin state
809 - performance optimization of AudioChannel::MixTo() and
810 AudioChannel::CopyTo() methods using GCC vector exensions
811 (if available)
812 - ASIO fixes: avoid initializing the device twice, avoid throwing
813 exception when getting parameters from a disconnected device
814
815 * MIDI driver:
816 - added JACK MIDI driver
817 - dispatch bank select as ordinary CC as well, the user might seriously
818 want to (mis)use it for some purpose ("fixed" in all current MIDI
819 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
820 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
821 CoreMidi or AU
822 - fixed mingw-w64 compilation error in MME driver
823 - made program change handling in MIDI thread real-time safe by
824 moving the logic to a non-RT thread
825 - fixed minor memory leak in ALSA driver
826
827 * instruments database:
828 - avoid time consuming samples scanning when adding instruments
829 to the instruments database

832 in the instruments database
833 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
834 - work-around for missing fnmatch function on Windows to make
835 instrument database compilable
836 - added instrument database support on Windows
837 works with both standalone mode and VST plugin.
838 the instruments DB file is located in
839 %USERPROFILE%\.linuxsampler\instruments.db which allows different
840 databases for each windows user
841 if no DB is present it automatically creates the .linuxsampler subdir
842 and then creates an empty DB
843 - fixed recursive import, which was broken on Windows
844
845 * Gigasampler format engine:
846 - fixed a memory leak that could happen when a channel was deleted
847 while notes were playing
848 - made it possible to load an instrument even if the audio thread
849 isn't running
850 - added partial support for the "Controller Triggered" MIDI rule,
851 enough for piano gigs with pedal noise samples
852 - minor fix: only mark FX sends as being modified if really the
853 respective FX send MIDI controller was used
854 - added support for GM global device volume SysEx message
855 (can be selected at compile time to either apply globally to the
856 whole sampler [default] or only to the sampler channels that are
857 connected to the respective MIDI input port the SysEx message arrived
858 on)
859 - bugfix: notes triggered at position 0 in the audio buffer were
860 sometimes wrongly killed in the same buffer, causing no sound to
861 be played
862 - added support for chromatic / drumkit mode Roland GS Sysex message
863 which is usally used to switch a part between chromatic sounds and
864 drumkit sounds (as opposed to their common default setting of MIDI
865 part 10 being a drumkit part and all other ones chromatic parts), in
866 LS however one can switch between the first 16 MIDI instrument maps
867 defined for the sampler
868 - made it possible to create multiple sample channels even if the
869 audio thread isn't running
870 - fixed crash when removing channel with active voices (#116)
871 - bugfix: on sample reference changes (instrument editor), only
872 un-cache the respective sample if it's really not used by any
873 sampler engine anymore
874 - re-cache samples in case they were changed by an instrument editor,
875 e.g. when a sample was added while playing (#82)
876 - fixed hanging notes which occured when note-off event had the exact
877 same time stamp as the voice's note-on event and occured both in the
878 same audio fragment cycle (fixes bug #112)
879 - added support for the "fine tune" and "pitch bend range"
880 instrument-level gig parameters
881 - fixed minor artifacts in pitch bend handling
882 - added support for GS Reset SysEx message
883 - allow gig files to use unlimited downward pitch shifting
884 - added a limit check for upward pitch shifting
885 - bugfix: sometimes, when playing a note twice fast, the second
886 note was silent
887 - fixed crash happening when a pitch bend event arrived at the
888 same time a new instrument was loading
889
890 * LSCP server:
891 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
892 react on MIDI data arriving on certain sampler channels (so far only
893 Note-On and Note-Off events are sent via this LSCP event)
894 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
895 react on MIDI data arriving on certain MIDI input devices (so far only
896 Note-On and Note-Off events are sent via this LSCP event)
897 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
898 SET DB_INSTRUMENT FILE_PATH
899 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
900 frontends to send MIDI messages to specific sampler channel
901 - added two additional fields to GET FILE INSTRUMENT INFO command -
902 KEY_BINDINGS and KEYSWITCH_BINDINGS
903 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
904 was incorrect
905 - Optimized the retrieval of the MIDI instrument mappings
906 - added new LSCP command "SET VOICES" to globally alter the maximum
907 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
908 be triggered respectively
909 - added new LSCP command "SET STREAMS" to globally alter the maximum
910 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
911 which will be triggered respectively
912 - bugfix: retry if "select" returns EINTR (this fixes a crash when
913 a gigedit file dialog is opened)
914 - close all connections when LSCPServer is deleted
915 - hard close of all sockets on exit
916 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
917 driver
918
919 * Bug fixes:
920 - fixed a crash which occurs when removing a sampler channel waiting
921 to start instrument loading after another channel
922 - fixed a crash which occurs when removing a sampler channel with
923 instrument loading in progress (bug #113)
924 - fixed termination caused by uncaught exception when adding MIDI
925 instrument with PERSISTENT load mode
926 - fixed possible iterator invalidations when resetting the sampler
927 - fixed memory leaks when issuing the following LSCP commands:
928 GET AUDIO_OUTPUT_DRIVER INFO
929 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
930 GET MIDI_INPUT_DRIVER INFO
931 GET MIDI_INPUT_DRIVER_PARAMETER INFO
932 - fixed possible compilation error when sqlite is not present
933 - fixed orphaned pointers when setting maximum voices limit (bug #118)
934 - fixed crash when changing the audio output device of a sampler
935 channel with loaded instrument and start playing notes
936 - fixed endless loop in Engine::SuspendAll() (bug #120)
937 - fixed a low-level atomic load function that was broken on 64-bit
938 PowerPC, which probably could cause crashes on that platform
939 - fixed a memory management error which could cause a crash when a
940 plugin was unloaded
941 - bugfix: two private structs had the same name, which could cause
942 problems if the linker chose the wrong constructor
943 - fixed low-level ConditionServer usage bug that caused lockups on
944 Windows
945
946
947 Version 0.5.1 (6 December 2007)
948
949 * packaging changes:
950 - added autoconf checks for pthread library
951 - added autoconf check for pthread bug found on certain NPTL-enabled
952 glibc versions (see Gentoo bug report #194076)
953 - added autoconf checks for MS Windows
954
955 * general changes:
956 - bugfix: the thread used by an editor plugin didn't die when the
957 editor closed
958 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
959 out all the space. operator--() did not apply size_mask after
960 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
961 order to avoid problems with the _NonVolatileReader functions.
962 - bugfix: Stream.h: added a missing divide by BytesPerSample in
963 GetWriteSpace(). Since this function is currently only used in
964 the stream's qsort() compare function, it didn't trigger any
965 bugs.
966 - Resampler.h, Synthesizer.h: cubic interpolation now works in
967 24bit mode too. Faster method to read 24bit words on little
968 endian machines (x86): replaced 3 byte reads + shifts with a 1
969 unaligned 32bit read and shift
970 - experimental support for MS Windows (MIDI input via MME, AUDIO
971 output via ASIO)
972 - made handling of SIGINT signal (Ctrl-C) a bit more robust
973 - support for monitoring the total number of active disk streams
974 (new LSCP commands: GET TOTAL_STREAM_COUNT,
975 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
976
977 * AUDIO driver:
978 - added Windows ASIO low latency audio driver
979
980 * MIDI driver:
981 - added MME Windows MIDI driver
982
983 * LSCP server:
984 - added support for Windows style path / filenames, however with
985 forward slash path separators instead of backslash
986 (i.e. "C:/foo/bar.gig")
987 - allow naughty liblscp to send non-string device parameters within
988 apostrophes as well
989 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
990 "LIST FILE INSTRUMENTS <file>" and
991 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
992 about an arbitrary instrument file on the system where the sampler is
993 running on
994
995 Version 0.5.0 (15 October 2007)
996
997 * packaging changes:
998 - config.h is not going to be installed along with liblinuxsampler's
999 API header files anymore
1000 - only the API relevant header (and source) files will be exported to
1001 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1002 - added completely new XCode project files for Mac OSX which is now
1003 capable to execute our autoconf environment, thus no need anymore
1004 to maintain the compile time configuration file (osx/version.h) for
1005 OSX manually (patch by Toshi Nagata)
1006 - fixed buggy boolean --enable-foo / --disable-foo configure script
1007 parameters
1008 - global.h now only covers global definitions that are needed for the
1009 C++ API header files, all implementation internal global definitions
1010 are now in global_private.h
1011 - atomic.h is not exposed to the C++ API anymore
1012 - no need to include config.h anymore for using LS's API header files
1013 - fixed warnings in API doc generation
1014
1015 * general changes:
1016 - replaced the old, confusing MIDI program change mechanism by a
1017 flexible MIDI instrument mapper which allows to map arbitrary
1018 (MIDI bank, MIDI program) pairs with arbitrary
1019 (engine type, instrument file, file index) triplets which will be
1020 loaded on the respective channel when such MIDI program change
1021 messages arrive, beside that, each entry allows to define a life-time
1022 strategy for the instrument, so the user can define whether the
1023 instrument should i.e. be permanently loaded (to be able to switch
1024 quickly among sounds) or i.e. loaded just on demand when the
1025 respective program change arrives (to safe RAM space), as well as a
1026 global volume factor for each entry, so the user can adjust the volume
1027 dynamic of his mapped instrument collection without having to modify
1028 the instrument files, also one can manage arbitrary amount of such
1029 MIDI instrument maps and assign each sampler channel individually
1030 a certain map, so that i.e. separation of normal instruments and
1031 drumkits is possible
1032 - new notification events for tracking changes to audio/MIDI devices,
1033 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1034 - sampler was limited to load max. 200 instruments in the background
1035 due to a constant size RingBuffer FIFO which is now replaced by a
1036 dynamic (unlimited) size std::list FIFO
1037 - added FX sends, these allow to route audio signals to arbitrary audio
1038 output channels for being processed by external effect processors
1039 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1040 controllers
1041 - global (sampler wide) volume can now be controlled at runtime
1042 - Implemented new, improved notification system
1043 - fixed compilation errors regarding OSX
1044 (patch by Toshi Nagata)
1045 - implemented instruments database
1046 - added support for escape sequences to the instruments database
1047 - added highly experimental support for on-the-fly instrument editing
1048 within the sampler's process (by using instrument editor plugins),
1049 you'll notice the new "Registered instrument editors:" message on
1050 startup, added a new LSCP command:
1051 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1052 to spawn a matching instrument editor for the instrument on the
1053 given sampler channel, the plugin path can be overridden at compile
1054 time with ./configure --enable-plugin-dir=/some/dir
1055 - added experimental code for synchronizing instrument editors hosted
1056 in the sampler's process to safely edit instruments while playing
1057 without a crash (hopefully) by either suspending single regions
1058 wherever possible or if unavoidable whole engine(s)
1059 - fixed several issues in fundamental "Thread" class: set scheduling
1060 policy and priority on thread level, set a minimum stack size for
1061 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1062 threads simply inherited properties of starting thread instead of
1063 setting their own policy and priority
1064 - minor fix in our automatic stack trace mechanism on crashes, the
1065 main process did not wait for the stack trace process to finish
1066 its output
1067 - fixed some minor memory leaks
1068 - reenabled assembly features support, at the moment only for
1069 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1070 - minor assembly fix in x86 features detection (don't use the PIC
1071 register, to avoid relocations in the text segment at runtime)
1072 - POSIX callback functions of Thread.h are hidden
1073
1074 * MIDI driver:
1075 - dispatch bank select (MSB and LSB) messages
1076
1077 * audio driver:
1078 - the ALSA audio output driver parameters now reflect the correct
1079 parameter value ranges for the respective selected sound card
1080 (patch by Till Wimmer, a bit fixed and extended)
1081
1082 * Gigasampler format engine:
1083 - if a filter is used and EG2 finishes before EG1, let the voice
1084 die when EG2 has finished (this fixes a problem with clicks and
1085 voice starvation for some gigs)
1086 - playback is no longer disabled during instrument loading
1087 - all notes playing on a channel that changes its instrument keep
1088 playing with the old instrument until they get a note off
1089 command
1090 - EG fix: a release value of zero could cause noises or crash
1091 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1092 - EG fine tuning: when attack is zero the EG starts at a level
1093 above max sustain level, which means that there is a decay phase
1094 even if sustain is 100%
1095 - more EG fixes: the level could sometimes go below zero and cause
1096 noises or crashes
1097 - minor fix of EGDecay (patch by Toshi Nagata)
1098 - fixed compiler error when --enable-override-filter-type was
1099 supplied to the configure script (fixes #46)
1100 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1101 instead of a fix value
1102 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1103 127 (solo mode) only kill voices if the respective mode really
1104 changed
1105
1106 * LSCP server:
1107 - fixed compile time error for old Bison versions
1108 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1109 - parser now supports extended ASCII character set
1110 (up to ASCII code 255, i.e. includes now umlauts and accents)
1111 - filename arguments in LSCP commands now allow to use escape
1112 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1113 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1114 code value like \xf2) (fixes bug #24)
1115 - the following LSCP commands now also support escape sequences for at
1116 least one of their text-based parameters (i.e. name, description):
1117 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1118 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1119 "SET DB_INSTRUMENT_DIRECTORY NAME",
1120 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1121 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1122 "FIND DB_INSTRUMENT_DIRECTORIES"
1123 - returns verbose syntax errors (line and column where syntax error
1124 occured, the unexpected character and the actually expected, possible
1125 character(s), the latter only if less than 5 possibilities)
1126 - made sure that LSCP syntax is not affected by gigedit locale
1127 settings
1128 - bugfix regarding strings parameter lists: all comma separated lists
1129 of strings were treated as being one string containing commas
1130 (fixes #57)
1131
1132 * Bug fixes:
1133 - fixed crash occurring on certain LSCP scripts (Bug 39)
1134 - another thread safety fix for lscp "load engine" and "set
1135 channel audio output device"
1136 - fixed a crash which occurs when reassigning the same engine
1137 on a sampler channel with connected MIDI device
1138 - fixed a crash which occurs when changing the number of ports of a MIDI
1139 device connected to a sampler channel to number less then or equal
1140 to the index of the port to which the sampler channel is connected.
1141 - The previous bindings were not been disconnected when altering
1142 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1143 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1144 - The active stream/voice count statistic was incorrect.
1145 - notification events were not been sent for some sampler
1146 channel changes
1147 - added default min and max values to restrict the number of allowed
1148 audio output channels and MIDI input ports
1149 - the connection to the PCM interface is now closed when destroying
1150 an audio output device
1151 - files with slash in their path or filename could not be loaded
1152
1153 * test cases:
1154 - updated and fixed (haven't been touched in a while)
1155
1156 Version 0.4.0 (24 November 2006)
1157
1158 * packaging changes:
1159 - changed deprecated copyright attribute to license; added ldconfig
1160 to post-(un)install steps; added devel package for liblinuxsampler;
1161 to linuxsampler.spec (RPM)
1162 - install necessary development header files for allowing 3rd party
1163 applications to link against liblinuxsampler
1164 - liblinuxsampler's API documentation can be generated with 'make docs'
1165 (Doxygen required)
1166 - added benchmark to automatically detect the best triangle LFO
1167 implementation (currently either an integer math solution or a
1168 di-harmonic approximation), automatic detection can be overriden
1169 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1170 configure script argument though (mandatory for cross-compilation)
1171 - do not automatically pick optimized gcc flags if the user already
1172 provided some on his own (as CXXFLAGS)
1173 - added compile time option to disable processing of All-Notes-Off MIDI
1174 messages
1175 - added compile time options to allow disabling the various audio and
1176 MIDI drivers
1177 - fixed automatic GCC CPU switch detection on PPC
1178 (patch by Ebrahim Mayat)
1179
1180 * Gigasampler format engine:
1181 - extensive synthesis optimization
1182 (reimplementation of EGs and LFO(s), removed synthesis parameter
1183 prerendering and the synthesis parameter matrix in general, splitting
1184 each audio fragment into subfragments now where each subfragment uses
1185 constant pitch and filter coefficients. The volume coefficient is
1186 linearly interpolated inside a subfragment, unless
1187 --disable-interpolate-volume is set.)
1188 - fine tuning of the EG modulation parameters
1189 - improved filter cutoff calculation by adding support for the
1190 following gig parameters: Cutoff freq (used when no cutoff
1191 controller is defined), Control invert, Minimum cutoff, Velocity
1192 curve and Velocity range. The keyboard tracking now scales
1193 cutoff frequency instead of resonance.
1194 - added support for gig parameter Resonance.
1195 - fixed bug in sysex handling (patch by Juan Linietsky)
1196 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1197 which can be overridden with --enable-global-attenuation
1198 - EG fixes: made the length of "attack hold" stage more
1199 accurate. Release stage can now start before attack stage
1200 ends. Cancel release didn't work when sustain was zero. Attack
1201 time now has a minimal value to prevent clicks.
1202 - fixed pitch changes larger than one octave
1203 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1204 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1205 all modes can be altered via standard GM messages, that is CC5 for
1206 altering portamento time, CC65 for enabling / disabling portamento
1207 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1208 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1209 parameter) and crossfade
1210 - added support for the "attenuation controller threshold" gig
1211 parameter
1212 - added smoothing of volume changes caused by control change
1213 messages
1214 - sample loop parameters are now taken from the DimensionRegion
1215 instead of the wave chunk
1216 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1217 not equal to a power of two
1218 - reimplementation of the filter algorithm. The new filter is more
1219 accurate and supports all gig filter types, including bandreject
1220 and lowpass turbo.
1221 - real support for 24 bit samples - samples are not truncated to
1222 16 bits anymore
1223 - support for aftertouch (channel pressure, not polyphonic
1224 aftertouch)
1225 - LFO1 behaviour fixed (dampening from max volume instead of
1226 amplifying from 0)
1227
1228 * LSCP server:
1229 - fixed application exit on broken pipe error (fixes bug #20)
1230 - fixed the notification messages delay due to lack of
1231 network activity (fixes bug #26)
1232 - fixed parser bug which occured on space(s) within device parameters
1233 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1234
1235 * audio driver:
1236 - added aRts audio output driver (by no means RT safe)
1237
1238 * MIDI driver:
1239 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1240 messages several times instead of once
1241 - API extension for MIDI drivers which already supply exact time stamps
1242 for events (i.e. for offline rendering based MIDI drivers)
1243 - added checks for bad MIDI data
1244
1245 * linuxsampler application:
1246 - show available sampler engine types on startup
1247
1248 * general changes:
1249 - support for muting sampler channels and solo mode of the same, two new
1250 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1251 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1252 introduced for this, the behavior is the same like on a mixer console
1253 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1254 --enable-process-muted-channels which can be used to enable the
1255 processing of muted channels.
1256 - support for sostenuto pedal
1257 - support for monitoring the total number of active voices
1258 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1259 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1260 - fixed some memory management errors
1261 - fixed some concurrency problems that could lead to crashes when
1262 LSCP commands were executed
1263 - fixed crash when instrument loading failed previously on the same
1264 sampler channel (fixes bug #36)
1265
1266 Version 0.3.3 (15 July 2005)
1267
1268 * packaging changes:
1269 - fixed compilation with gcc 4.0
1270
1271 * Gigasampler format engine:
1272 - LFO preprocessing was performed even though the respective LFO was
1273 disabled by the instrument patch (minor efficiency fix)
1274 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1275 for volume ramp downs in the same fragment (needed for current voice
1276 stealing implementation) then simply inform the user with a warning
1277 about possible click sounds and reduce the volume ramp down
1278 appropriately instead of cancelling the audio device connection
1279
1280 Version 0.3.2 (24 June 2005)
1281
1282 * packaging changes:
1283 - updated autotools build files to compile on OS X
1284 (conditional compilation of CoreMIDI and MidiShare drivers)
1285 - hand-crafted assembly optimization code can be disabled with
1286 './configure --disable-asm' (definitely not recommended)
1287 - fixed 'make dist' rule to include all necessary files
1288 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1289 (due to 'dist-bzip2' automake option)
1290
1291 * Gigasampler format engine:
1292 - support for the gig parameters for "release velocity response" curves
1293 - fine tuning of the EGADSR envelope
1294 - volume of release triggered samples now depends on note-on velocity,
1295 note length and gig parameter "release trigger decay" instead of
1296 note-off velocity.
1297 - revised voice stealing
1298 (fixes crash and endless loop caused by voice stealing)
1299 - don't reset scale tuning on instrument or audio output device change
1300 - handle key group conflicts right at the beginning of each fragment
1301 instead of when the respective voice is actually launched
1302 (fixes undefined behavior if stolen voices belonged to a key group -
1303 this case was followed by a "killed voice survived" error message)
1304 - fixed minor issue with null/silence samples
1305 (those stole voices even though they don't need a voice at all which
1306 resulted in "voice stealing didn't work out" messages)
1307 - don't reset volume, pan, pitch and MIDI controller values on
1308 instrument or audio output device change
1309
1310 * LSCP server:
1311 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1312 - fixed LSCP event "CHANNEL_INFO" notification
1313 (e.g. did not notify on volume changes or MIDI program change events)
1314
1315 * linuxsampler application:
1316 - added command line parameters --lscp-addr and --lscp-port to override
1317 default IP address and port of LSCP server
1318
1319 Version 0.3.1 (24 May 2005)
1320
1321 * initial release
