File size: 71202 byte(s)
* NKSP: Fixed polyphonic variables not being reset to zero
  after usage.
* Bumped version (2.0.0.svn48).

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 - Fixed polyphonic variables not being reset to zero after usage.
166
167 * Instruments DB:
168 - Fixed memory access bug of general DB access code which lead to
169 undefined behavior.
170 - Cleanup of instruments DB file creation and opening code.
171 - The instrument DB path of linuxsampler's --create-instruments-db argument
172 is now optional, if it is missing, then a default location is used.
173 - Added support for scanning SFZ (.sfz) files.
174 - Added support for scanning Sound Font (.sf2) files.
175 - Fixed undefined DB transaction behavior.

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

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

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

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

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

610 - Added support for moving cursor left/right with arrow keys.
611 - Added support for built-in LSCP reference documentation, which will
612 automatically show the relevant LSCP reference section on screen as soon

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

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

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

731 - fixed building with libgig installed in a non-standard directory
732 - minor fix in configure for mmsystem.h detection on MinGW
733 - Windows: look for editor plugins and Fantasia using base
734 directory of liblinuxsampler dll (look in the same directory and one
735 directory above)
736 - configure script fix: removed unconditional use of SSE
737 - fixed building with sqlite installed in a non-standard directory
738 - when cross-compiling, don't try to create instruments.db
739 - fix for new mingw-w64 version, which has usleep
740
741 * general changes:
742 - bugfix: on some POSIX systems instrument editor plugins refused to
743 load as we used a non-portable Linux specific struct field
744 (fixes bug #70, patch by Ronald Baljeu)
745 - fixed endless loop which occured when loading an instrument editor
746 plugin DLL on Windows systems failed
747 - fixed memory leaks that occurred when liblinuxsampler was unloaded
748 - optimized the SynchronizedConfig class so it doesn't wait
749 unnecessarily long after an update
750 - added support for notifying instrument editors on note-on / note-off
751 events (e.g. to highlight the pressed keys on the virtual keyboard
752 of gigedit)
753 - added support for triggering notes by instrument editors (see above)
754 - be verbose on DLL load errors (on Linux)
755 - fixed di-harmonic triangle LFO implementation (this LFO implementation
756 is only used by very few systems, most pick the int math
757 implementation, which is usually faster)
758 - fixes for audio drivers with varying buffer sizes
759 - experimental support for running LinuxSampler as a DSSI, LV2 and
760 VST plugin
761 - notification events for stream/voice count statistics are now sent
762 only when there are actual changes
763 - added memory ordering constraints to improve stability on
764 multi-core and multi-cpu systems
765 - maximum voices and disk streams can now be altered at runtime
766 - fixed CPU feature detection on x86_64 (maybe fixes #108)
767 - automatic stacktrace mechanism is now turned off by default and can
768 be switched on by command line option "--stacktrace" (the automatic
769 stacktrace mechanism seems to be broken on most systems at the moment)
770 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
771 a pointer to the launched InstrumentEditor object
772 - added optional 3rd party user data parameter for following
773 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
774 InstrumentEditor::Launch(),
775 InstrumentManager::LaunchInstrumentEditor()
776 - theoretical fix: made SynchronizedConfig follow C++0x memory
777 model more strictly
778 - fixes for using large audio device buffers
779 - Windows: add the installation directory to the DLL search path
780 when loading an editor plugin (solves problems with VST and
781 gigedit on systems with other GTK versions installed)
782 - updated linuxsampler man page
783
784 * audio driver:
785 - removed the nonsense audio channel constraint (which was hard coded to
786 max. 100 audio channels) for most audio drivers
787 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
788 opposed to the LSCP specs
789 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
790 reflected the wrong value
791 - fixed a memory management bug in ASIO driver
792 - Makefile fix: JACK_CFLAGS wasn't used
793 - JACK: use jack_client_open instead of the deprecated
794 jack_client_new
795 - added (experimental) CoreAudio driver
796 - applied old fixes to the ASIO driver that were included in the
797 previous binary release but accidentally never committed to CVS
798 (fixes #117)
799 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
800 win64)
801 - VST: added support for sample rate and buffer size changes
802 - VST: close editor (Fantasia) when the VST is removed
803 - VST: avoid opening Fantasia more than once for each VST instance
804 - VST: export main function as "main" on Linux too (fix for
805 energyXT)
806 - VST: changed number of output channels from one stereo to 16
807 stereo
808 - added channel routing, fxsends and midi maps to the settings
809 stored in the plugin state
810 - performance optimization of AudioChannel::MixTo() and
811 AudioChannel::CopyTo() methods using GCC vector exensions
812 (if available)
813 - ASIO fixes: avoid initializing the device twice, avoid throwing
814 exception when getting parameters from a disconnected device
815
816 * MIDI driver:
817 - added JACK MIDI driver
818 - dispatch bank select as ordinary CC as well, the user might seriously
819 want to (mis)use it for some purpose ("fixed" in all current MIDI
820 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
821 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
822 CoreMidi or AU
823 - fixed mingw-w64 compilation error in MME driver
824 - made program change handling in MIDI thread real-time safe by
825 moving the logic to a non-RT thread
826 - fixed minor memory leak in ALSA driver
827
828 * instruments database:
829 - avoid time consuming samples scanning when adding instruments
830 to the instruments database
831 - added support for handling lost files in the instruments database

833 in the instruments database
834 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
835 - work-around for missing fnmatch function on Windows to make
836 instrument database compilable
837 - added instrument database support on Windows
838 works with both standalone mode and VST plugin.
839 the instruments DB file is located in
840 %USERPROFILE%\.linuxsampler\instruments.db which allows different
841 databases for each windows user
842 if no DB is present it automatically creates the .linuxsampler subdir
843 and then creates an empty DB
844 - fixed recursive import, which was broken on Windows
845
846 * Gigasampler format engine:
847 - fixed a memory leak that could happen when a channel was deleted
848 while notes were playing
849 - made it possible to load an instrument even if the audio thread
850 isn't running
851 - added partial support for the "Controller Triggered" MIDI rule,
852 enough for piano gigs with pedal noise samples
853 - minor fix: only mark FX sends as being modified if really the
854 respective FX send MIDI controller was used
855 - added support for GM global device volume SysEx message
856 (can be selected at compile time to either apply globally to the
857 whole sampler [default] or only to the sampler channels that are
858 connected to the respective MIDI input port the SysEx message arrived
859 on)
860 - bugfix: notes triggered at position 0 in the audio buffer were
861 sometimes wrongly killed in the same buffer, causing no sound to
862 be played
863 - added support for chromatic / drumkit mode Roland GS Sysex message
864 which is usally used to switch a part between chromatic sounds and
865 drumkit sounds (as opposed to their common default setting of MIDI
866 part 10 being a drumkit part and all other ones chromatic parts), in
867 LS however one can switch between the first 16 MIDI instrument maps
868 defined for the sampler
869 - made it possible to create multiple sample channels even if the
870 audio thread isn't running
871 - fixed crash when removing channel with active voices (#116)
872 - bugfix: on sample reference changes (instrument editor), only
873 un-cache the respective sample if it's really not used by any
874 sampler engine anymore
875 - re-cache samples in case they were changed by an instrument editor,
876 e.g. when a sample was added while playing (#82)
877 - fixed hanging notes which occured when note-off event had the exact
878 same time stamp as the voice's note-on event and occured both in the
879 same audio fragment cycle (fixes bug #112)
880 - added support for the "fine tune" and "pitch bend range"
881 instrument-level gig parameters
882 - fixed minor artifacts in pitch bend handling
883 - added support for GS Reset SysEx message
884 - allow gig files to use unlimited downward pitch shifting
885 - added a limit check for upward pitch shifting
886 - bugfix: sometimes, when playing a note twice fast, the second
887 note was silent
888 - fixed crash happening when a pitch bend event arrived at the
889 same time a new instrument was loading
890
891 * LSCP server:
892 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
893 react on MIDI data arriving on certain sampler channels (so far only
894 Note-On and Note-Off events are sent via this LSCP event)
895 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
896 react on MIDI data arriving on certain MIDI input devices (so far only
897 Note-On and Note-Off events are sent via this LSCP event)
898 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
899 SET DB_INSTRUMENT FILE_PATH
900 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
901 frontends to send MIDI messages to specific sampler channel
902 - added two additional fields to GET FILE INSTRUMENT INFO command -
903 KEY_BINDINGS and KEYSWITCH_BINDINGS
904 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
905 was incorrect
906 - Optimized the retrieval of the MIDI instrument mappings
907 - added new LSCP command "SET VOICES" to globally alter the maximum
908 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
909 be triggered respectively
910 - added new LSCP command "SET STREAMS" to globally alter the maximum
911 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
912 which will be triggered respectively
913 - bugfix: retry if "select" returns EINTR (this fixes a crash when
914 a gigedit file dialog is opened)
915 - close all connections when LSCPServer is deleted
916 - hard close of all sockets on exit
917 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
918 driver
919
920 * Bug fixes:
921 - fixed a crash which occurs when removing a sampler channel waiting
922 to start instrument loading after another channel
923 - fixed a crash which occurs when removing a sampler channel with
924 instrument loading in progress (bug #113)
925 - fixed termination caused by uncaught exception when adding MIDI
926 instrument with PERSISTENT load mode
927 - fixed possible iterator invalidations when resetting the sampler
928 - fixed memory leaks when issuing the following LSCP commands:
929 GET AUDIO_OUTPUT_DRIVER INFO
930 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
931 GET MIDI_INPUT_DRIVER INFO
932 GET MIDI_INPUT_DRIVER_PARAMETER INFO
933 - fixed possible compilation error when sqlite is not present
934 - fixed orphaned pointers when setting maximum voices limit (bug #118)
935 - fixed crash when changing the audio output device of a sampler
936 channel with loaded instrument and start playing notes
937 - fixed endless loop in Engine::SuspendAll() (bug #120)
938 - fixed a low-level atomic load function that was broken on 64-bit
939 PowerPC, which probably could cause crashes on that platform
940 - fixed a memory management error which could cause a crash when a
941 plugin was unloaded
942 - bugfix: two private structs had the same name, which could cause
943 problems if the linker chose the wrong constructor
944 - fixed low-level ConditionServer usage bug that caused lockups on
945 Windows
946
947
948 Version 0.5.1 (6 December 2007)
949
950 * packaging changes:
951 - added autoconf checks for pthread library
952 - added autoconf check for pthread bug found on certain NPTL-enabled
953 glibc versions (see Gentoo bug report #194076)
954 - added autoconf checks for MS Windows
955
956 * general changes:
957 - bugfix: the thread used by an editor plugin didn't die when the
958 editor closed
959 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
960 out all the space. operator--() did not apply size_mask after
961 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
962 order to avoid problems with the _NonVolatileReader functions.
963 - bugfix: Stream.h: added a missing divide by BytesPerSample in
964 GetWriteSpace(). Since this function is currently only used in
965 the stream's qsort() compare function, it didn't trigger any
966 bugs.
967 - Resampler.h, Synthesizer.h: cubic interpolation now works in
968 24bit mode too. Faster method to read 24bit words on little
969 endian machines (x86): replaced 3 byte reads + shifts with a 1
970 unaligned 32bit read and shift
971 - experimental support for MS Windows (MIDI input via MME, AUDIO
972 output via ASIO)
973 - made handling of SIGINT signal (Ctrl-C) a bit more robust
974 - support for monitoring the total number of active disk streams
975 (new LSCP commands: GET TOTAL_STREAM_COUNT,
976 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
977
978 * AUDIO driver:
979 - added Windows ASIO low latency audio driver
980
981 * MIDI driver:
982 - added MME Windows MIDI driver
983
984 * LSCP server:
985 - added support for Windows style path / filenames, however with
986 forward slash path separators instead of backslash
987 (i.e. "C:/foo/bar.gig")
988 - allow naughty liblscp to send non-string device parameters within
989 apostrophes as well
990 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
991 "LIST FILE INSTRUMENTS <file>" and
992 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
993 about an arbitrary instrument file on the system where the sampler is
994 running on
995
996 Version 0.5.0 (15 October 2007)
997
998 * packaging changes:
999 - config.h is not going to be installed along with liblinuxsampler's
1000 API header files anymore
1001 - only the API relevant header (and source) files will be exported to
1002 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1003 - added completely new XCode project files for Mac OSX which is now
1004 capable to execute our autoconf environment, thus no need anymore
1005 to maintain the compile time configuration file (osx/version.h) for
1006 OSX manually (patch by Toshi Nagata)
1007 - fixed buggy boolean --enable-foo / --disable-foo configure script
1008 parameters
1009 - global.h now only covers global definitions that are needed for the
1010 C++ API header files, all implementation internal global definitions
1011 are now in global_private.h
1012 - atomic.h is not exposed to the C++ API anymore
1013 - no need to include config.h anymore for using LS's API header files
1014 - fixed warnings in API doc generation
1015
1016 * general changes:
1017 - replaced the old, confusing MIDI program change mechanism by a
1018 flexible MIDI instrument mapper which allows to map arbitrary
1019 (MIDI bank, MIDI program) pairs with arbitrary
1020 (engine type, instrument file, file index) triplets which will be
1021 loaded on the respective channel when such MIDI program change
1022 messages arrive, beside that, each entry allows to define a life-time
1023 strategy for the instrument, so the user can define whether the
1024 instrument should i.e. be permanently loaded (to be able to switch
1025 quickly among sounds) or i.e. loaded just on demand when the
1026 respective program change arrives (to safe RAM space), as well as a
1027 global volume factor for each entry, so the user can adjust the volume
1028 dynamic of his mapped instrument collection without having to modify
1029 the instrument files, also one can manage arbitrary amount of such
1030 MIDI instrument maps and assign each sampler channel individually
1031 a certain map, so that i.e. separation of normal instruments and
1032 drumkits is possible
1033 - new notification events for tracking changes to audio/MIDI devices,
1034 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1035 - sampler was limited to load max. 200 instruments in the background
1036 due to a constant size RingBuffer FIFO which is now replaced by a
1037 dynamic (unlimited) size std::list FIFO
1038 - added FX sends, these allow to route audio signals to arbitrary audio
1039 output channels for being processed by external effect processors
1040 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1041 controllers
1042 - global (sampler wide) volume can now be controlled at runtime
1043 - Implemented new, improved notification system
1044 - fixed compilation errors regarding OSX
1045 (patch by Toshi Nagata)
1046 - implemented instruments database
1047 - added support for escape sequences to the instruments database
1048 - added highly experimental support for on-the-fly instrument editing
1049 within the sampler's process (by using instrument editor plugins),
1050 you'll notice the new "Registered instrument editors:" message on
1051 startup, added a new LSCP command:
1052 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1053 to spawn a matching instrument editor for the instrument on the
1054 given sampler channel, the plugin path can be overridden at compile
1055 time with ./configure --enable-plugin-dir=/some/dir
1056 - added experimental code for synchronizing instrument editors hosted
1057 in the sampler's process to safely edit instruments while playing
1058 without a crash (hopefully) by either suspending single regions
1059 wherever possible or if unavoidable whole engine(s)
1060 - fixed several issues in fundamental "Thread" class: set scheduling
1061 policy and priority on thread level, set a minimum stack size for
1062 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1063 threads simply inherited properties of starting thread instead of
1064 setting their own policy and priority
1065 - minor fix in our automatic stack trace mechanism on crashes, the
1066 main process did not wait for the stack trace process to finish
1067 its output
1068 - fixed some minor memory leaks
1069 - reenabled assembly features support, at the moment only for
1070 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1071 - minor assembly fix in x86 features detection (don't use the PIC
1072 register, to avoid relocations in the text segment at runtime)
1073 - POSIX callback functions of Thread.h are hidden
1074
1075 * MIDI driver:
1076 - dispatch bank select (MSB and LSB) messages
1077
1078 * audio driver:
1079 - the ALSA audio output driver parameters now reflect the correct
1080 parameter value ranges for the respective selected sound card
1081 (patch by Till Wimmer, a bit fixed and extended)
1082
1083 * Gigasampler format engine:
1084 - if a filter is used and EG2 finishes before EG1, let the voice
1085 die when EG2 has finished (this fixes a problem with clicks and
1086 voice starvation for some gigs)
1087 - playback is no longer disabled during instrument loading
1088 - all notes playing on a channel that changes its instrument keep
1089 playing with the old instrument until they get a note off
1090 command
1091 - EG fix: a release value of zero could cause noises or crash
1092 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1093 - EG fine tuning: when attack is zero the EG starts at a level
1094 above max sustain level, which means that there is a decay phase
1095 even if sustain is 100%
1096 - more EG fixes: the level could sometimes go below zero and cause
1097 noises or crashes
1098 - minor fix of EGDecay (patch by Toshi Nagata)
1099 - fixed compiler error when --enable-override-filter-type was
1100 supplied to the configure script (fixes #46)
1101 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1102 instead of a fix value
1103 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1104 127 (solo mode) only kill voices if the respective mode really
1105 changed
1106
1107 * LSCP server:
1108 - fixed compile time error for old Bison versions
1109 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1110 - parser now supports extended ASCII character set
1111 (up to ASCII code 255, i.e. includes now umlauts and accents)
1112 - filename arguments in LSCP commands now allow to use escape
1113 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1114 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1115 code value like \xf2) (fixes bug #24)
1116 - the following LSCP commands now also support escape sequences for at
1117 least one of their text-based parameters (i.e. name, description):
1118 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1119 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1120 "SET DB_INSTRUMENT_DIRECTORY NAME",
1121 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1122 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1123 "FIND DB_INSTRUMENT_DIRECTORIES"
1124 - returns verbose syntax errors (line and column where syntax error
1125 occured, the unexpected character and the actually expected, possible
1126 character(s), the latter only if less than 5 possibilities)
1127 - made sure that LSCP syntax is not affected by gigedit locale
1128 settings
1129 - bugfix regarding strings parameter lists: all comma separated lists
1130 of strings were treated as being one string containing commas
1131 (fixes #57)
1132
1133 * Bug fixes:
1134 - fixed crash occurring on certain LSCP scripts (Bug 39)
1135 - another thread safety fix for lscp "load engine" and "set
1136 channel audio output device"
1137 - fixed a crash which occurs when reassigning the same engine
1138 on a sampler channel with connected MIDI device
1139 - fixed a crash which occurs when changing the number of ports of a MIDI
1140 device connected to a sampler channel to number less then or equal
1141 to the index of the port to which the sampler channel is connected.
1142 - The previous bindings were not been disconnected when altering
1143 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1144 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1145 - The active stream/voice count statistic was incorrect.
1146 - notification events were not been sent for some sampler
1147 channel changes
1148 - added default min and max values to restrict the number of allowed
1149 audio output channels and MIDI input ports
1150 - the connection to the PCM interface is now closed when destroying
1151 an audio output device
1152 - files with slash in their path or filename could not be loaded
1153
1154 * test cases:
1155 - updated and fixed (haven't been touched in a while)
1156
1157 Version 0.4.0 (24 November 2006)
1158
1159 * packaging changes:
1160 - changed deprecated copyright attribute to license; added ldconfig
1161 to post-(un)install steps; added devel package for liblinuxsampler;
1162 to linuxsampler.spec (RPM)
1163 - install necessary development header files for allowing 3rd party
1164 applications to link against liblinuxsampler
1165 - liblinuxsampler's API documentation can be generated with 'make docs'
1166 (Doxygen required)
1167 - added benchmark to automatically detect the best triangle LFO
1168 implementation (currently either an integer math solution or a
1169 di-harmonic approximation), automatic detection can be overriden
1170 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1171 configure script argument though (mandatory for cross-compilation)
1172 - do not automatically pick optimized gcc flags if the user already
1173 provided some on his own (as CXXFLAGS)
1174 - added compile time option to disable processing of All-Notes-Off MIDI
1175 messages
1176 - added compile time options to allow disabling the various audio and
1177 MIDI drivers
1178 - fixed automatic GCC CPU switch detection on PPC
1179 (patch by Ebrahim Mayat)
1180
1181 * Gigasampler format engine:
1182 - extensive synthesis optimization
1183 (reimplementation of EGs and LFO(s), removed synthesis parameter
1184 prerendering and the synthesis parameter matrix in general, splitting
1185 each audio fragment into subfragments now where each subfragment uses
1186 constant pitch and filter coefficients. The volume coefficient is
1187 linearly interpolated inside a subfragment, unless
1188 --disable-interpolate-volume is set.)
1189 - fine tuning of the EG modulation parameters
1190 - improved filter cutoff calculation by adding support for the
1191 following gig parameters: Cutoff freq (used when no cutoff
1192 controller is defined), Control invert, Minimum cutoff, Velocity
1193 curve and Velocity range. The keyboard tracking now scales
1194 cutoff frequency instead of resonance.
1195 - added support for gig parameter Resonance.
1196 - fixed bug in sysex handling (patch by Juan Linietsky)
1197 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1198 which can be overridden with --enable-global-attenuation
1199 - EG fixes: made the length of "attack hold" stage more
1200 accurate. Release stage can now start before attack stage
1201 ends. Cancel release didn't work when sustain was zero. Attack
1202 time now has a minimal value to prevent clicks.
1203 - fixed pitch changes larger than one octave
1204 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1205 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1206 all modes can be altered via standard GM messages, that is CC5 for
1207 altering portamento time, CC65 for enabling / disabling portamento
1208 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1209 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1210 parameter) and crossfade
1211 - added support for the "attenuation controller threshold" gig
1212 parameter
1213 - added smoothing of volume changes caused by control change
1214 messages
1215 - sample loop parameters are now taken from the DimensionRegion
1216 instead of the wave chunk
1217 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1218 not equal to a power of two
1219 - reimplementation of the filter algorithm. The new filter is more
1220 accurate and supports all gig filter types, including bandreject
1221 and lowpass turbo.
1222 - real support for 24 bit samples - samples are not truncated to
1223 16 bits anymore
1224 - support for aftertouch (channel pressure, not polyphonic
1225 aftertouch)
1226 - LFO1 behaviour fixed (dampening from max volume instead of
1227 amplifying from 0)
1228
1229 * LSCP server:
1230 - fixed application exit on broken pipe error (fixes bug #20)
1231 - fixed the notification messages delay due to lack of
1232 network activity (fixes bug #26)
1233 - fixed parser bug which occured on space(s) within device parameters
1234 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1235
1236 * audio driver:
1237 - added aRts audio output driver (by no means RT safe)
1238
1239 * MIDI driver:
1240 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1241 messages several times instead of once
1242 - API extension for MIDI drivers which already supply exact time stamps
1243 for events (i.e. for offline rendering based MIDI drivers)
1244 - added checks for bad MIDI data
1245
1246 * linuxsampler application:
1247 - show available sampler engine types on startup
1248
1249 * general changes:
1250 - support for muting sampler channels and solo mode of the same, two new
1251 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1252 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1253 introduced for this, the behavior is the same like on a mixer console
1254 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1255 --enable-process-muted-channels which can be used to enable the
1256 processing of muted channels.
1257 - support for sostenuto pedal
1258 - support for monitoring the total number of active voices
1259 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1260 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1261 - fixed some memory management errors
1262 - fixed some concurrency problems that could lead to crashes when
1263 LSCP commands were executed
1264 - fixed crash when instrument loading failed previously on the same
1265 sampler channel (fixes bug #36)
1266
1267 Version 0.3.3 (15 July 2005)
1268
1269 * packaging changes:
1270 - fixed compilation with gcc 4.0
1271
1272 * Gigasampler format engine:
1273 - LFO preprocessing was performed even though the respective LFO was
1274 disabled by the instrument patch (minor efficiency fix)
1275 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1276 for volume ramp downs in the same fragment (needed for current voice
1277 stealing implementation) then simply inform the user with a warning
1278 about possible click sounds and reduce the volume ramp down
1279 appropriately instead of cancelling the audio device connection
1280
1281 Version 0.3.2 (24 June 2005)
1282
1283 * packaging changes:
1284 - updated autotools build files to compile on OS X
1285 (conditional compilation of CoreMIDI and MidiShare drivers)
1286 - hand-crafted assembly optimization code can be disabled with
1287 './configure --disable-asm' (definitely not recommended)
1288 - fixed 'make dist' rule to include all necessary files
1289 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1290 (due to 'dist-bzip2' automake option)
1291
1292 * Gigasampler format engine:
1293 - support for the gig parameters for "release velocity response" curves
1294 - fine tuning of the EGADSR envelope
1295 - volume of release triggered samples now depends on note-on velocity,
1296 note length and gig parameter "release trigger decay" instead of
1297 note-off velocity.
1298 - revised voice stealing
1299 (fixes crash and endless loop caused by voice stealing)
1300 - don't reset scale tuning on instrument or audio output device change
1301 - handle key group conflicts right at the beginning of each fragment
1302 instead of when the respective voice is actually launched
1303 (fixes undefined behavior if stolen voices belonged to a key group -
1304 this case was followed by a "killed voice survived" error message)
1305 - fixed minor issue with null/silence samples
1306 (those stole voices even though they don't need a voice at all which
1307 resulted in "voice stealing didn't work out" messages)
1308 - don't reset volume, pan, pitch and MIDI controller values on
1309 instrument or audio output device change
1310
1311 * LSCP server:
1312 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1313 - fixed LSCP event "CHANNEL_INFO" notification
1314 (e.g. did not notify on volume changes or MIDI program change events)
1315
1316 * linuxsampler application:
1317 - added command line parameters --lscp-addr and --lscp-port to override
1318 default IP address and port of LSCP server
1319
1320 Version 0.3.1 (24 May 2005)
1321
1322 * initial release
