* NKSP: Implemented built-in script function "change_vol_time()".
* NKSP: Implemented built-in script function "change_tune_time()".
* NKSP: Implemented built-in script function "fade_in()".
* NKSP: Implemented built-in script function "fade_out()".
* NKSP: Fixed acceptance of wrong data type of parameters passed to
  built-in script functions "change_vol()", "change_tune()",
  "change_pan()", "change_cutoff()", "change_reso()",
  "change_attack()", "change_decay()", "change_release()",
  "change_amp_lfo_depth()", "change_amp_lfo_freq()",
  "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
* Bumped version (2.0.0.svn45).

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
47 * packaging changes:
48 - removed unnecessary dependency to libuuid
49 (originated by libgig's usage of it)
50 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51 auto detect whether it (sh/c)ould output its messages in color.
52
53 * Real-time instrument scripts:
54 - Implemented scheduler for delayed MIDI events and for suspended scripts.
55 - Built-in script function "wait()": implemented support for function's
56 "duration-us" argument, thus scripts using this function are now
57 correctly resumed after the requested amount of microseconds.
58 - Built-in script function "play_note()": implemented support for
59 function's "duration-us" argument, thus notes triggered with this
60 argument are now correctly released after the requested amount of
61 microseconds.
62 - Fix: script events were not cleared when engine channel was reset,
63 potentially causing undefined behavior.
64 - Fixed crash which happened when trying to reference an undeclared
65 variable.
66 - Built-in script function "play_note()": Added support for passing
67 special value -1 for "duration-us" argument, which will cause the
68 triggered note to be released once the original note was released.
69 - Instrument script classes now exported with the liblinuxsampler C++ API.
70 - Added new API method ScriptVM::syntaxHighlighting() which provides
71 a convenient syntax highlighting backend for external instrument
72 script editor applications.
73 - Added new C++ API class "ScriptVMFactory".
74 - Extended parser issues to provide not only first line and first
75 column, but also last line and last column of issue (thus marking
76 the precise span of the issue within the source code).
77 - Reload script automatically after being modified by an instrument
78 editor.
79 - NKSP language grammar correction: allow empty event handler bodies
80 like "on note end on".
81 - Implemented built-in script function "change_vol()".
82 - Implemented built-in script function "change_tune()".
83 - Implemented built-in script function "change_pan()".
84 - Implemented built-in script function "change_cutoff()".
85 - Implemented built-in script function "change_reso()".
86 - Implemented built-in script function "event_status()".
87 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89 "event_status()" function.
90 - NKSP language: Added support for bitwise operators ".or.", ".and."
91 and ".not.".
92 - NKSP language scanner: Fixed IDs matching to require at least one
93 character (i.e. when matching function names or variable names).
94 - NKSP language scanner: disabled unusued rules.
95 - Fixed behavior of play_note() and note_off() functions which must
96 be distinguished engine internally from "real" MIDI note on/off
97 events in order to avoid misbehaviors like hanging notes.
98 - Implemented built-in script variable "$KSP_TIMER".
99 - Implemented built-in script variable "$NKSP_REAL_TIMER".
100 - Implemented built-in script variable "$NKSP_PERF_TIMER".
101 - Implemented built-in script variable "$ENGINE_UPTIME".
102 - Implemented built-in script function "inc()".
103 - Implemented built-in script function "dec()".
104 - NKSP language fix: division expressions were evaluated too often.
105 - NKSP language fix: string concatenation operator was right
106 associative instead of left (to right).
107 - NKSP language correction: allow empty statements in entire language
108 (i.e. "if end if").
109 - Implemented built-in script function "stop_wait()".
110 - Implemented built-in script variable "$NI_CALLBACK_ID".
111 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113 - Added support for read-only built-in variables (respectively
114 handled by the script parser).
115 - Added built-in script constant "$NI_CB_TYPE_INIT".
116 - Added built-in script constant "$NI_CB_TYPE_NOTE".
117 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119 - NKSP Language: Added support for user defined script functions.
120 - Implemented built-in script function "change_attack()".
121 - Implemented built-in script function "change_decay()".
122 - Implemented built-in script function "change_release()".
123 - Fixed all change_*() built-in script functions to apply their
124 synthesis parameter changes immediately in case the respective note
125 was triggered at the same time, instead of scheduling the parameter
126 change, especially because it would cause some parameter types's
127 changes either to be ramped (i.e. change_vol()) or other types even
128 to have not effect at all (i.e. change_attack()).
129 - Implemented built-in script function "sh_left()".
130 - Implemented built-in script function "sh_right()".
131 - Implemented built-in script function "min()".
132 - Implemented built-in script function "max()".
133 - NKSP Fix: "init" event handler was not always executed when a script
134 was loaded.
135 - NKSP built-in wait() script function: abort script execution if
136 a negative or zero wait time was passed as argument (since this is
137 a common indication of a bug either of the script or even of the
138 engine, which could lead to RT instability or even worse).
139 - ScriptVM: Implemented automatic suspension of RT safety
140 threatening scripts.
141 - Provide more user friendly error messages on syntax errors.
142 - Fixed NKSP parser warning "Not a statement" when assigning an
143 initializer list to an array variable.
144 - Implemented built-in script array variable "%ALL_EVENTS".
145 - Implemented built-in script function "in_range()".
146 - Implemented built-in script function "change_amp_lfo_depth()".
147 - Implemented built-in script function "change_amp_lfo_freq()".
148 - Implemented built-in script function "change_pitch_lfo_depth()".
149 - Implemented built-in script function "change_pitch_lfo_freq()".
150 - Implemented built-in script function "change_vol_time()".
151 - Implemented built-in script function "change_tune_time()".
152 - Implemented built-in script function "fade_in()".
153 - Implemented built-in script function "fade_out()".
154 - Fixed acceptance of wrong data type of parameters passed to built-in
155 script functions "change_vol()", "change_tune()", "change_pan()",
156 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
157 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
158 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
159
160 * Instruments DB:
161 - Fixed memory access bug of general DB access code which lead to
162 undefined behavior.
163 - Cleanup of instruments DB file creation and opening code.
164 - The instrument DB path of linuxsampler's --create-instruments-db argument
165 is now optional, if it is missing, then a default location is used.
166 - Added support for scanning SFZ (.sfz) files.
167 - Added support for scanning Sound Font (.sf2) files.
168 - Fixed undefined DB transaction behavior.
169

192 - fixed linkage error when building with
193 LDFLAGS="-Wl,--no-undefined" (#190)
194 - fixed compilation with Clang 3.2
195 - removed usage of deprecated Automake variable INCLUDES
196 - fixed building with C++11
197 - build fix: ChangeFlagRelaxed.h was missing in makefile
198 - build fix: libsndfile compiler flags were missing in some
199 makefiles
200 - fix for building with bison 3.0 (#202)
201 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
202 on the process's main thread
203 - fixed build error on newer MinGW
204 - support building with older jack versions
205 - support building with spaces in vst sdk path
206 - enabled automake 'subdir-objects' option and moved external
207 source references (vst, au, asio) from makefiles to cpp files,
208 in order to get rid of warnings from automake 1.14
209
210 * general changes:
211 - Refactoring: moved the independent code from
212 the Gigasampler format engine to base classes
213 - command line option '--profile' is currently disabled, since the
214 respective profiling code is currently broken
215 - Introduced support for optional environment variable
216 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
217 where the sampler shall look for instrument editor plugins
218 (patch by Luis Garrido, slightly modified).
219 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
220 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
221 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
222 note (in this implementation of the sampler its simply hard routed to
223 the 1st effect send of the sampler channel, no matter what the actual
224 effect type is)
225 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
226 note (in this implementation of the sampler its simply hard routed to
227 the 2nd effect send of the sampler channel, no matter what the actual
228 effect type is)
229 - implemented support for internal LADSPA effects
230 - raised limit of program change queue from 100 to 512
231 (as suggested by Alex Stone)
232 - implemented sine LFO, pulse LFO and saw LFO
233 - experimental support for per voice equalization
234 - added command line option --exec-after-init
235 - Introduced new C++ API method:
236 EngineChannel::InstrumentFileName(int index)
237 allowing to retrieve the whole list of files used for the loaded
238 instrument on an engine channel (a.k.a. part). Some GigaStudio
239 instruments for example are splitted over several files like
240 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
241 - Added new C++ API method Sampler::GetGlobalMaxVoices().
242 - Added new C++ API method Sampler::GetGlobalMaxStreams().
243 - Added new C++ API method Sampler::SetGlobalMaxVoices().
244 - Added new C++ API method Sampler::SetGlobalMaxStreams().
245 - Various "const" and "restrict" optimizations.
246 - all engines: add pan CC value to instrument pan parameter before
247 applying panning, instead of using two separate pan functions in
248 series (#182)
249 - added a lock guard class for exception safe mutex handling and
250 used it everywhere appropriate
251 - Immediately apply scale tuning changes to active voices.
252 - Exposed scale tuning to C++ API (along to the already existing standard
253 SysEx way).
254 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
255 and broken for ppc64. (Seq_cst loads and stores are actually not
256 used in LS, so the bug wasn't noticable.)
257 - lsatomic.h: added ARMv7 support
258 - Added support for multiple MIDI input ports per sampler channel (and
259 added various new C++ methods for this new feature / design change, old
260 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
261 as deprecated but are still there and should provide full behavior
262 backward compatibility).
263 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
264 unsafe and caused compilation error with clang 2.x).
265 - Bugfix: only process the latest MIDI program change event.
266 - Introducing the LSCP shell, which provides convenient control of the
267 sampler from the command line by providing LSCP aware features.
268 - VirtualMidiDevice: Added support for program change.
269 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
270 - VirtualMidiDevice: Added support for pitch bend.
271 - Aftertouch: extended API to explicitly handle channel pressure and
272 polyphonic key pressure events (so far polyphonic pressure was not
273 supported at all, and channel pressure was rerouted as CC128 but not
274 used so far).
275 - Added initial support for real-time instrument scripts. The script VM
276 code is shared by all sampler engine implemementations, however only the
277 gig file format currently provides support for storing instrument scripts
278 (as LinuxSampler extension to the original GigaStudio 4 format).
279

281 - implemented the "round robin keyboard" dimension
282 - fixed round robin and random dimensions for cases when number of
283 dimension zones is not a power of two
284 - made round robin use a counter for each region instead of each
285 key
286 - bugfix: pitch LFO controller "internal+aftertouch" was broken
287 - bugfix: filter keyboard tracking was broken
288 - filter performance fix (an unnecessary copy was made of the
289 filter parameters in each sub fragment)
290 - handle special case when pan parameter in gig file has max or
291 min value
292 - Exclusive Groups: don't ever stop voices of the same note,
293 doesn't sound naturally with a drumkit
294 - fixed EG1 modulation when attack or release is zero
295 - Fixed support for 'aftertouch' attenuation controller.
296 - Fixed crash that happened with velocity split sounds under certain
297 conditions (see also previous commit on libgig).
298 - fixed behaviour of filter LFO
299
300 * SFZ format engine:
301 - Initial implementation (not usable yet)
302 - added support for v2 multiple stage envelope generators
303 - added a fine-tuned v1 envelope generator instead of using the
304 one from the gig engine
305 - fixed memory leak and memory handling errors
306 - added support for trigger=first, trigger=legato and sw_previous
307 - allow non-numerical key values ("C#4" for example)
308 - "key" opcode now sets pitch_keycenter too
309 - fixed error when unloading instrument with same sample used by
310 multiple regions
311 - added some opcode aliases, like loopmode for loop_mode, to be
312 more compatible
313 - added support for trigger=release and rt_decay
314 - added support for off_mode=normal
315 - added support for random, seq_position, seq_length and volume

330 - added support for loop_mode=one_shot
331 - fixed playback of 16 bit wav files on big endian CPUs
332 - added support for Ogg Vorbis sample files
333 - use loop markers from sample file if loop_start and loop_end are
334 not set in sfz file
335 - implemeted filters. Filter types: lowpass, bandpass, bandreject
336 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
337 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
338 cutoff_cc, cutoff_chanaft.
339 - bugfix: zero ampeg_sustain didn't work

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

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

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

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

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

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

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

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

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