* NKSP: Implemented built-in script function "stop_wait()".
* NKSP: Implemented built-in script variable "$NI_CALLBACK_ID".
* NKSP: Implemented built-in script variable "$NI_CALLBACK_TYPE".
* NKSP: Implemented built-in script variable "$NKSP_IGNORE_WAIT".
* NKSP: Added support for read-only built-in variables
  (respectively handled by the script parser).
* NKSP: Added built-in script constant "$NI_CB_TYPE_INIT".
* NKSP: Added built-in script constant "$NI_CB_TYPE_NOTE".
* NKSP: Added built-in script constant "$NI_CB_TYPE_RELEASE".
* NKSP: Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
* Bumped version (2.0.0.svn17).

1 Version SVN trunk (?)
3 * SFZ format engine:
4 - added support for <global>, <master> and #define (patch by Alby M)
6 * general changes:
7 - fixed printf type errors (mostly in debug messages)
8 - use unique_ptr instead of auto_ptr when building with C++11
9 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10 allowing to sort data efficiently in real-time safe manner.
11 - RTList class: added methods for moving/inserting elements to arbitrary
12 position within a list.
13 - RTList class: added method fromPtr() for creating an Iterator object from
14 a raw element pointer.
15 - Attempt to partly fix resetting engine channels vs. resetting engine, an
16 overall cleanup of the Reset*(), ConnectAudioDevice(),
17 DisconnectAudioDevice() API methods would still be desirable though,
18 because the current situation is still inconsistent and error prone.
19 - Active voices are now internally grouped to "Note" objects, instead of
20 being directly assigned to a keyboard key. This allows more fine graded
21 processing of voices, which is i.e. required for certain instrument
22 script features.
23 - Fix: Release trigger voices were not spawned on sustain pedal up
24 (CC #64) events.
25 - Fix: Release trigger voices can now also distinguish correctly between
26 note-off and sustain pedal up events.
28 * packaging changes:
29 - removed unnecessary dependency to libuuid
30 (originated by libgig's usage of it)
31 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32 auto detect whether it (sh/c)ould output its messages in color.
34 * Real-time instrument scripts:
35 - Implemented scheduler for delayed MIDI events and for suspended scripts.
36 - Built-in script function "wait()": implemented support for function's
37 "duration-us" argument, thus scripts using this function are now
38 correctly resumed after the requested amount of microseconds.
39 - Built-in script function "play_note()": implemented support for
40 function's "duration-us" argument, thus notes triggered with this
41 argument are now correctly released after the requested amount of
42 microseconds.
43 - Fix: script events were not cleared when engine channel was reset,
44 potentially causing undefined behavior.
45 - Fixed crash which happened when trying to reference an undeclared
46 variable.
47 - Built-in script function "play_note()": Added support for passing
48 special value -1 for "duration-us" argument, which will cause the
49 triggered note to be released once the original note was released.
50 - Instrument script classes now exported with the liblinuxsampler C++ API.
51 - Added new API method ScriptVM::syntaxHighlighting() which provides
52 a convenient syntax highlighting backend for external instrument
53 script editor applications.
54 - Added new C++ API class "ScriptVMFactory".
55 - Extended parser issues to provide not only first line and first
56 column, but also last line and last column of issue (thus marking
57 the precise span of the issue within the source code).
58 - Reload script automatically after being modified by an instrument
59 editor.
60 - NKSP language grammar correction: allow empty event handler bodies
61 like "on note end on".
62 - Implemented built-in script function "change_vol()".
63 - Implemented built-in script function "change_tune()".
64 - Implemented built-in script function "change_pan()".
65 - Implemented built-in script function "change_cutoff()".
66 - Implemented built-in script function "change_reso()".
67 - Implemented built-in script function "event_status()".
68 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70 "event_status()" function.
71 - NKSP language: Added support for bitwise operators ".or.", ".and."
72 and ".not.".
73 - NKSP language scanner: Fixed IDs matching to require at least one
74 character (i.e. when matching function names or variable names).
75 - NKSP language scanner: disabled unusued rules.
76 - Fixed behavior of play_note() and note_off() functions which must
77 be distinguished engine internally from "real" MIDI note on/off
78 events in order to avoid misbehaviors like hanging notes.
79 - Implemented built-in script variable "$KSP_TIMER".
80 - Implemented built-in script variable "$NKSP_REAL_TIMER".
81 - Implemented built-in script variable "$NKSP_PERF_TIMER".
82 - Implemented built-in script variable "$ENGINE_UPTIME".
83 - Implemented built-in script function "inc()".
84 - Implemented built-in script function "dec()".
85 - NKSP language fix: division expressions were evaluated too often.
86 - NKSP language fix: string concatenation operator was right
87 associative instead of left (to right).
88 - NKSP language correction: allow empty statements in entire language
89 (i.e. "if end if").
90 - Implemented built-in script function "stop_wait()".
91 - Implemented built-in script variable "$NI_CALLBACK_ID".
92 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94 - Added support for read-only built-in variables (respectively
95 handled by the script parser).
96 - Added built-in script constant "$NI_CB_TYPE_INIT".
97 - Added built-in script constant "$NI_CB_TYPE_NOTE".
98 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

123 - fixed linkage error when building with
124 LDFLAGS="-Wl,--no-undefined" (#190)
125 - fixed compilation with Clang 3.2
126 - removed usage of deprecated Automake variable INCLUDES

128 - build fix: ChangeFlagRelaxed.h was missing in makefile
129 - build fix: libsndfile compiler flags were missing in some
130 makefiles
131 - fix for building with bison 3.0 (#202)
132 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
133 on the process's main thread
134 - fixed build error on newer MinGW
135 - support building with older jack versions
136 - support building with spaces in vst sdk path
137 - enabled automake 'subdir-objects' option and moved external
138 source references (vst, au, asio) from makefiles to cpp files,
139 in order to get rid of warnings from automake 1.14
141 * general changes:
142 - Refactoring: moved the independent code from
143 the Gigasampler format engine to base classes
144 - command line option '--profile' is currently disabled, since the
145 respective profiling code is currently broken
146 - Introduced support for optional environment variable
147 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
148 where the sampler shall look for instrument editor plugins
149 (patch by Luis Garrido, slightly modified).
150 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
151 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
152 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
153 note (in this implementation of the sampler its simply hard routed to
154 the 1st effect send of the sampler channel, no matter what the actual
155 effect type is)
156 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
157 note (in this implementation of the sampler its simply hard routed to
158 the 2nd effect send of the sampler channel, no matter what the actual
159 effect type is)
160 - implemented support for internal LADSPA effects
161 - raised limit of program change queue from 100 to 512
162 (as suggested by Alex Stone)
163 - implemented sine LFO, pulse LFO and saw LFO
164 - experimental support for per voice equalization
165 - added command line option --exec-after-init
166 - Introduced new C++ API method:
167 EngineChannel::InstrumentFileName(int index)
168 allowing to retrieve the whole list of files used for the loaded
169 instrument on an engine channel (a.k.a. part). Some GigaStudio
170 instruments for example are splitted over several files like
171 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
172 - Added new C++ API method Sampler::GetGlobalMaxVoices().
173 - Added new C++ API method Sampler::GetGlobalMaxStreams().
174 - Added new C++ API method Sampler::SetGlobalMaxVoices().
175 - Added new C++ API method Sampler::SetGlobalMaxStreams().
176 - Various "const" and "restrict" optimizations.
177 - all engines: add pan CC value to instrument pan parameter before
178 applying panning, instead of using two separate pan functions in
179 series (#182)
180 - added a lock guard class for exception safe mutex handling and
181 used it everywhere appropriate
182 - Immediately apply scale tuning changes to active voices.
183 - Exposed scale tuning to C++ API (along to the already existing standard
184 SysEx way).
185 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
186 and broken for ppc64. (Seq_cst loads and stores are actually not
187 used in LS, so the bug wasn't noticable.)
188 - lsatomic.h: added ARMv7 support
189 - Added support for multiple MIDI input ports per sampler channel (and
190 added various new C++ methods for this new feature / design change, old
191 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
192 as deprecated but are still there and should provide full behavior
193 backward compatibility).
194 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
195 unsafe and caused compilation error with clang 2.x).
196 - Bugfix: only process the latest MIDI program change event.
197 - Introducing the LSCP shell, which provides convenient control of the
198 sampler from the command line by providing LSCP aware features.
199 - VirtualMidiDevice: Added support for program change.
200 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
201 - VirtualMidiDevice: Added support for pitch bend.
202 - Aftertouch: extended API to explicitly handle channel pressure and
203 polyphonic key pressure events (so far polyphonic pressure was not
204 supported at all, and channel pressure was rerouted as CC128 but not
205 used so far).
206 - Added initial support for real-time instrument scripts. The script VM
207 code is shared by all sampler engine implemementations, however only the
208 gig file format currently provides support for storing instrument scripts
209 (as LinuxSampler extension to the original GigaStudio 4 format).
211 * Gigasampler format engine:
212 - implemented the "round robin keyboard" dimension
213 - fixed round robin and random dimensions for cases when number of
214 dimension zones is not a power of two
215 - made round robin use a counter for each region instead of each
216 key
217 - bugfix: pitch LFO controller "internal+aftertouch" was broken
218 - bugfix: filter keyboard tracking was broken
219 - filter performance fix (an unnecessary copy was made of the
220 filter parameters in each sub fragment)
221 - handle special case when pan parameter in gig file has max or
222 min value
223 - Exclusive Groups: don't ever stop voices of the same note,
224 doesn't sound naturally with a drumkit
225 - fixed EG1 modulation when attack or release is zero
226 - Fixed support for 'aftertouch' attenuation controller.
227 - Fixed crash that happened with velocity split sounds under certain
228 conditions (see also previous commit on libgig).
229 - fixed behaviour of filter LFO
231 * SFZ format engine:
232 - Initial implementation (not usable yet)
233 - added support for v2 multiple stage envelope generators
234 - added a fine-tuned v1 envelope generator instead of using the
235 one from the gig engine
236 - fixed memory leak and memory handling errors
237 - added support for trigger=first, trigger=legato and sw_previous
238 - allow non-numerical key values ("C#4" for example)
239 - "key" opcode now sets pitch_keycenter too
240 - fixed error when unloading instrument with same sample used by
241 multiple regions
242 - added some opcode aliases, like loopmode for loop_mode, to be
243 more compatible
244 - added support for trigger=release and rt_decay
245 - added support for off_mode=normal
246 - added support for random, seq_position, seq_length and volume
247 - added v1 LFO opcodes to parser (no support in engine yet)

249 - fine-tuned the default velocity curve
250 - added support for transpose
251 - fixed crash when using sw_down/up
252 - improved logic for sw_lokey/hikey/up/down/last
253 - added more v1 aliases to parser
254 - reduced memory usage for sfz data
255 - RT-safeness: avoid malloc in audio thread
256 - fixed a bug that could cause voice stealing to fail
257 - optimized sample lookup
258 - improved support for exclusive groups (group, off_by and
259 off_mode)
260 - added support for controller triggered regions (on_locc/on_hicc)
261 - added support for loop_mode=one_shot
262 - fixed playback of 16 bit wav files on big endian CPUs
263 - added support for Ogg Vorbis sample files
264 - use loop markers from sample file if loop_start and loop_end are
265 not set in sfz file
266 - implemeted filters. Filter types: lowpass, bandpass, bandreject
267 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
268 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
269 cutoff_cc, cutoff_chanaft.
270 - bugfix: zero ampeg_sustain didn't work

410 incorrectly set to two. This caused silence in Cubase 5.
411 - save engine type (gig, sfz or sf2) in plugin state
412 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
413 64 bit Windows

423 loaded a second time (this time it's for Linux and Mac, previous
424 similar fix was for Windows)
425 - thread safety fixes for the instrument loading thread
426 - LV2: use the new lv2 package if present

428 Linux, the Fantasia jar should be placed in <prefix>/share/java)
429 - VST: fixed crashes on Linux Ardour and EnergyXT
430 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
431 port and audio channel routing for DSSI plugins are now visible.
432 - LV2: use urid and atom extensions instead of deprecated uri-map
433 and event
434 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

439 - VST: implemented retrieval and switching of programs using the
440 sampler's internal MIDI instrument mapping system
442 * Instrument editor interface:

445 spawned for. This allows the instrument editors to interact more actively
446 with the sampler.
448 * MIDI driver:
449 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
450 the ALSA sequencer client name

459 the driver will automatically connect to other CoreMIDI clients' ports
460 (e.g. external MIDI devices being attached to the Mac)
461 - added support for MIDI note on velocity filter
462 - CoreMIDI: fixed memory deallocation error
463 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
464 virtual keyboards in frontends / instrument editors being stuck.
465 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
466 - Implemented missing handling of MIDI "running status".
467 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
468 - MME bugfix: driver wasn't closed properly

479 RT context.
480 - ASIO driver: removed compiler warnings
481 - CoreAudio: fixed minor error handling bug
482 - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

527 - Added support for auto completion by tab key.
528 - Show currently available auto completion while typing.
529 - Added support for browsing command history with up / down keys.
530 - Show all possible next symbols immediately right to the current command

532 be the case in other shells).
533 - Added support for moving cursor left/right with arrow keys.
534 - Added support for built-in LSCP reference documentation, which will
535 automatically show the relevant LSCP reference section on screen as soon

592 channel to a different engine type
593 - fixed crash when deleting a sampler channel or changing engine
594 type while an instrument load was in progress
595 - bugfix: playing a note while changing the instrument could cause
596 a crash, or give "Handing back unknown region" error messages
597 - bugfix: calling SET VOICES (which Fantasia does on start and
598 refresh) could cause instruments to be unloaded
599 - Mac OS X: fixed name collision of enum in EffectControl and
600 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
601 - Mac OS X: fixed hanging threads
602 - Windows: disabled the previous thread fix on non-Mac systems, as
603 it caused hanging threads on Windows
604 - Fixed possible crashes due to corrupted MIDI/audio device list
605 after MIDI/audio device creation failure
606 - When creating MIDI instrument map entries with "PERSISTENT" type, the
607 instruments were uselessly precached with zero samples, however it still
608 took the full preloading time and on 1st program change the respective
609 instrument was completely reloaded again.
610 - fixed handling of rapid bank select and program change messages
611 sent to the same sampler channel (patch from the Open Octave
612 project, slightly adjusted)

631 crashes and noise on such transitions).
632 - ignore missing LADSPA paths without ignoring valid LADSPA paths
633 (fixes #208)
634 - Fixed bug in LSCP grammar definition which caused a statement like
635 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
636 practically irrelevant, however it caused problems with the new LSCP
637 shell's auto completion feature).
638 - Fixed MIDI program change messages being ignored if quickly executed
639 after each other (fixes #231).
641 Version 1.0.0 (31 July 2009)
643 * packaging changes:
644 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

654 - minor fix in configure for mmsystem.h detection on MinGW
655 - Windows: look for editor plugins and Fantasia using base
656 directory of liblinuxsampler dll (look in the same directory and one
657 directory above)
658 - configure script fix: removed unconditional use of SSE
659 - fixed building with sqlite installed in a non-standard directory
660 - when cross-compiling, don't try to create instruments.db
661 - fix for new mingw-w64 version, which has usleep
663 * general changes:
664 - bugfix: on some POSIX systems instrument editor plugins refused to
665 load as we used a non-portable Linux specific struct field
666 (fixes bug #70, patch by Ronald Baljeu)
667 - fixed endless loop which occured when loading an instrument editor
668 plugin DLL on Windows systems failed
669 - fixed memory leaks that occurred when liblinuxsampler was unloaded
670 - optimized the SynchronizedConfig class so it doesn't wait
671 unnecessarily long after an update

673 events (e.g. to highlight the pressed keys on the virtual keyboard
674 of gigedit)
675 - added support for triggering notes by instrument editors (see above)
676 - be verbose on DLL load errors (on Linux)
677 - fixed di-harmonic triangle LFO implementation (this LFO implementation

679 implementation, which is usually faster)
680 - fixes for audio drivers with varying buffer sizes
681 - experimental support for running LinuxSampler as a DSSI, LV2 and
682 VST plugin
683 - notification events for stream/voice count statistics are now sent
684 only when there are actual changes
685 - added memory ordering constraints to improve stability on
686 multi-core and multi-cpu systems
687 - maximum voices and disk streams can now be altered at runtime
688 - fixed CPU feature detection on x86_64 (maybe fixes #108)
689 - automatic stacktrace mechanism is now turned off by default and can
690 be switched on by command line option "--stacktrace" (the automatic
691 stacktrace mechanism seems to be broken on most systems at the moment)
692 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
693 a pointer to the launched InstrumentEditor object
694 - added optional 3rd party user data parameter for following
695 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
696 InstrumentEditor::Launch(),
697 InstrumentManager::LaunchInstrumentEditor()
698 - theoretical fix: made SynchronizedConfig follow C++0x memory
699 model more strictly
700 - fixes for using large audio device buffers
701 - Windows: add the installation directory to the DLL search path
702 when loading an editor plugin (solves problems with VST and
703 gigedit on systems with other GTK versions installed)
704 - updated linuxsampler man page
706 * audio driver:
707 - removed the nonsense audio channel constraint (which was hard coded to
708 max. 100 audio channels) for most audio drivers
709 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
710 opposed to the LSCP specs
711 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
712 reflected the wrong value
713 - fixed a memory management bug in ASIO driver
714 - Makefile fix: JACK_CFLAGS wasn't used
715 - JACK: use jack_client_open instead of the deprecated
716 jack_client_new
717 - added (experimental) CoreAudio driver
718 - applied old fixes to the ASIO driver that were included in the
719 previous binary release but accidentally never committed to CVS
720 (fixes #117)
721 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
722 win64)
723 - VST: added support for sample rate and buffer size changes
724 - VST: close editor (Fantasia) when the VST is removed
725 - VST: avoid opening Fantasia more than once for each VST instance
726 - VST: export main function as "main" on Linux too (fix for
727 energyXT)
728 - VST: changed number of output channels from one stereo to 16
729 stereo
730 - added channel routing, fxsends and midi maps to the settings
731 stored in the plugin state
732 - performance optimization of AudioChannel::MixTo() and
733 AudioChannel::CopyTo() methods using GCC vector exensions
734 (if available)
735 - ASIO fixes: avoid initializing the device twice, avoid throwing
736 exception when getting parameters from a disconnected device
738 * MIDI driver:
739 - added JACK MIDI driver
740 - dispatch bank select as ordinary CC as well, the user might seriously
741 want to (mis)use it for some purpose ("fixed" in all current MIDI
742 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
743 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
744 CoreMidi or AU
745 - fixed mingw-w64 compilation error in MME driver
746 - made program change handling in MIDI thread real-time safe by
747 moving the logic to a non-RT thread
748 - fixed minor memory leak in ALSA driver
750 * instruments database:
751 - avoid time consuming samples scanning when adding instruments
752 to the instruments database
753 - added support for handling lost files in the instruments database
754 - Implemented option for adding instruments in separate directories
755 in the instruments database
756 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
757 - work-around for missing fnmatch function on Windows to make
758 instrument database compilable
759 - added instrument database support on Windows
760 works with both standalone mode and VST plugin.
761 the instruments DB file is located in
762 %USERPROFILE%\.linuxsampler\instruments.db which allows different
763 databases for each windows user
764 if no DB is present it automatically creates the .linuxsampler subdir
765 and then creates an empty DB
766 - fixed recursive import, which was broken on Windows
768 * Gigasampler format engine:
769 - fixed a memory leak that could happen when a channel was deleted
770 while notes were playing
771 - made it possible to load an instrument even if the audio thread
772 isn't running
773 - added partial support for the "Controller Triggered" MIDI rule,
774 enough for piano gigs with pedal noise samples
775 - minor fix: only mark FX sends as being modified if really the
776 respective FX send MIDI controller was used
777 - added support for GM global device volume SysEx message
778 (can be selected at compile time to either apply globally to the
779 whole sampler [default] or only to the sampler channels that are
780 connected to the respective MIDI input port the SysEx message arrived
781 on)
782 - bugfix: notes triggered at position 0 in the audio buffer were
783 sometimes wrongly killed in the same buffer, causing no sound to
784 be played
785 - added support for chromatic / drumkit mode Roland GS Sysex message
786 which is usally used to switch a part between chromatic sounds and
787 drumkit sounds (as opposed to their common default setting of MIDI
788 part 10 being a drumkit part and all other ones chromatic parts), in
789 LS however one can switch between the first 16 MIDI instrument maps
790 defined for the sampler
791 - made it possible to create multiple sample channels even if the
792 audio thread isn't running
793 - fixed crash when removing channel with active voices (#116)
794 - bugfix: on sample reference changes (instrument editor), only
795 un-cache the respective sample if it's really not used by any
796 sampler engine anymore
797 - re-cache samples in case they were changed by an instrument editor,
798 e.g. when a sample was added while playing (#82)
799 - fixed hanging notes which occured when note-off event had the exact
800 same time stamp as the voice's note-on event and occured both in the
801 same audio fragment cycle (fixes bug #112)
802 - added support for the "fine tune" and "pitch bend range"
803 instrument-level gig parameters
804 - fixed minor artifacts in pitch bend handling
805 - added support for GS Reset SysEx message
806 - allow gig files to use unlimited downward pitch shifting
807 - added a limit check for upward pitch shifting
808 - bugfix: sometimes, when playing a note twice fast, the second
809 note was silent
810 - fixed crash happening when a pitch bend event arrived at the
811 same time a new instrument was loading
813 * LSCP server:
814 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
815 react on MIDI data arriving on certain sampler channels (so far only
816 Note-On and Note-Off events are sent via this LSCP event)
817 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
818 react on MIDI data arriving on certain MIDI input devices (so far only
819 Note-On and Note-Off events are sent via this LSCP event)
820 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
822 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
823 frontends to send MIDI messages to specific sampler channel
824 - added two additional fields to GET FILE INSTRUMENT INFO command -
826 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
827 was incorrect
828 - Optimized the retrieval of the MIDI instrument mappings
829 - added new LSCP command "SET VOICES" to globally alter the maximum
830 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
831 be triggered respectively
832 - added new LSCP command "SET STREAMS" to globally alter the maximum
833 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
834 which will be triggered respectively
835 - bugfix: retry if "select" returns EINTR (this fixes a crash when
836 a gigedit file dialog is opened)
837 - close all connections when LSCPServer is deleted
838 - hard close of all sockets on exit
839 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
840 driver
842 * Bug fixes:
843 - fixed a crash which occurs when removing a sampler channel waiting
844 to start instrument loading after another channel
845 - fixed a crash which occurs when removing a sampler channel with
846 instrument loading in progress (bug #113)
847 - fixed termination caused by uncaught exception when adding MIDI
848 instrument with PERSISTENT load mode
849 - fixed possible iterator invalidations when resetting the sampler
850 - fixed memory leaks when issuing the following LSCP commands:
855 - fixed possible compilation error when sqlite is not present
856 - fixed orphaned pointers when setting maximum voices limit (bug #118)
857 - fixed crash when changing the audio output device of a sampler
858 channel with loaded instrument and start playing notes
859 - fixed endless loop in Engine::SuspendAll() (bug #120)
860 - fixed a low-level atomic load function that was broken on 64-bit
861 PowerPC, which probably could cause crashes on that platform
862 - fixed a memory management error which could cause a crash when a
863 plugin was unloaded
864 - bugfix: two private structs had the same name, which could cause
865 problems if the linker chose the wrong constructor
866 - fixed low-level ConditionServer usage bug that caused lockups on
867 Windows
870 Version 0.5.1 (6 December 2007)
872 * packaging changes:
873 - added autoconf checks for pthread library
874 - added autoconf check for pthread bug found on certain NPTL-enabled
875 glibc versions (see Gentoo bug report #194076)
876 - added autoconf checks for MS Windows
878 * general changes:
879 - bugfix: the thread used by an editor plugin didn't die when the
880 editor closed
881 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
882 out all the space. operator--() did not apply size_mask after
883 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
884 order to avoid problems with the _NonVolatileReader functions.
885 - bugfix: Stream.h: added a missing divide by BytesPerSample in
886 GetWriteSpace(). Since this function is currently only used in
887 the stream's qsort() compare function, it didn't trigger any
888 bugs.
889 - Resampler.h, Synthesizer.h: cubic interpolation now works in
890 24bit mode too. Faster method to read 24bit words on little
891 endian machines (x86): replaced 3 byte reads + shifts with a 1
892 unaligned 32bit read and shift
893 - experimental support for MS Windows (MIDI input via MME, AUDIO
894 output via ASIO)
895 - made handling of SIGINT signal (Ctrl-C) a bit more robust
896 - support for monitoring the total number of active disk streams
897 (new LSCP commands: GET TOTAL_STREAM_COUNT,
900 * AUDIO driver:
901 - added Windows ASIO low latency audio driver
903 * MIDI driver:
904 - added MME Windows MIDI driver
906 * LSCP server:
907 - added support for Windows style path / filenames, however with
908 forward slash path separators instead of backslash
909 (i.e. "C:/foo/bar.gig")
910 - allow naughty liblscp to send non-string device parameters within
911 apostrophes as well
912 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
913 "LIST FILE INSTRUMENTS <file>" and
914 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
915 about an arbitrary instrument file on the system where the sampler is
916 running on
918 Version 0.5.0 (15 October 2007)
920 * packaging changes:
921 - config.h is not going to be installed along with liblinuxsampler's
922 API header files anymore
923 - only the API relevant header (and source) files will be exported to
924 the Doxygen API documentation (explicitly listed in Doxyfile.in)
925 - added completely new XCode project files for Mac OSX which is now
926 capable to execute our autoconf environment, thus no need anymore
927 to maintain the compile time configuration file (osx/version.h) for
928 OSX manually (patch by Toshi Nagata)
929 - fixed buggy boolean --enable-foo / --disable-foo configure script
930 parameters
931 - global.h now only covers global definitions that are needed for the
932 C++ API header files, all implementation internal global definitions
933 are now in global_private.h
934 - atomic.h is not exposed to the C++ API anymore
935 - no need to include config.h anymore for using LS's API header files
936 - fixed warnings in API doc generation
938 * general changes:
939 - replaced the old, confusing MIDI program change mechanism by a
940 flexible MIDI instrument mapper which allows to map arbitrary
941 (MIDI bank, MIDI program) pairs with arbitrary
942 (engine type, instrument file, file index) triplets which will be
943 loaded on the respective channel when such MIDI program change
944 messages arrive, beside that, each entry allows to define a life-time
945 strategy for the instrument, so the user can define whether the
946 instrument should i.e. be permanently loaded (to be able to switch
947 quickly among sounds) or i.e. loaded just on demand when the
948 respective program change arrives (to safe RAM space), as well as a
949 global volume factor for each entry, so the user can adjust the volume
950 dynamic of his mapped instrument collection without having to modify
951 the instrument files, also one can manage arbitrary amount of such
952 MIDI instrument maps and assign each sampler channel individually
953 a certain map, so that i.e. separation of normal instruments and
954 drumkits is possible
955 - new notification events for tracking changes to audio/MIDI devices,
956 MIDI instrument maps, MIDI instruments, FX sends, global volume.
957 - sampler was limited to load max. 200 instruments in the background
958 due to a constant size RingBuffer FIFO which is now replaced by a
959 dynamic (unlimited) size std::list FIFO
960 - added FX sends, these allow to route audio signals to arbitrary audio
961 output channels for being processed by external effect processors
962 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
963 controllers
964 - global (sampler wide) volume can now be controlled at runtime
965 - Implemented new, improved notification system
966 - fixed compilation errors regarding OSX
967 (patch by Toshi Nagata)
968 - implemented instruments database
969 - added support for escape sequences to the instruments database
970 - added highly experimental support for on-the-fly instrument editing
971 within the sampler's process (by using instrument editor plugins),
972 you'll notice the new "Registered instrument editors:" message on
973 startup, added a new LSCP command:
974 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
975 to spawn a matching instrument editor for the instrument on the
976 given sampler channel, the plugin path can be overridden at compile
977 time with ./configure --enable-plugin-dir=/some/dir
978 - added experimental code for synchronizing instrument editors hosted
979 in the sampler's process to safely edit instruments while playing
980 without a crash (hopefully) by either suspending single regions
981 wherever possible or if unavoidable whole engine(s)
982 - fixed several issues in fundamental "Thread" class: set scheduling
983 policy and priority on thread level, set a minimum stack size for
984 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
985 threads simply inherited properties of starting thread instead of
986 setting their own policy and priority
987 - minor fix in our automatic stack trace mechanism on crashes, the
988 main process did not wait for the stack trace process to finish
989 its output
990 - fixed some minor memory leaks
991 - reenabled assembly features support, at the moment only for
992 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
993 - minor assembly fix in x86 features detection (don't use the PIC
994 register, to avoid relocations in the text segment at runtime)
995 - POSIX callback functions of Thread.h are hidden
997 * MIDI driver:
998 - dispatch bank select (MSB and LSB) messages
1000 * audio driver:
1001 - the ALSA audio output driver parameters now reflect the correct
1002 parameter value ranges for the respective selected sound card
1003 (patch by Till Wimmer, a bit fixed and extended)
1005 * Gigasampler format engine:
1006 - if a filter is used and EG2 finishes before EG1, let the voice
1007 die when EG2 has finished (this fixes a problem with clicks and
1008 voice starvation for some gigs)
1009 - playback is no longer disabled during instrument loading
1010 - all notes playing on a channel that changes its instrument keep
1011 playing with the old instrument until they get a note off
1012 command
1013 - EG fix: a release value of zero could cause noises or crash
1014 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1015 - EG fine tuning: when attack is zero the EG starts at a level
1016 above max sustain level, which means that there is a decay phase
1017 even if sustain is 100%
1018 - more EG fixes: the level could sometimes go below zero and cause
1019 noises or crashes
1020 - minor fix of EGDecay (patch by Toshi Nagata)
1021 - fixed compiler error when --enable-override-filter-type was
1022 supplied to the configure script (fixes #46)
1023 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1024 instead of a fix value
1025 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1026 127 (solo mode) only kill voices if the respective mode really
1027 changed
1029 * LSCP server:
1030 - fixed compile time error for old Bison versions
1031 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1032 - parser now supports extended ASCII character set
1033 (up to ASCII code 255, i.e. includes now umlauts and accents)
1034 - filename arguments in LSCP commands now allow to use escape
1035 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1036 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1037 code value like \xf2) (fixes bug #24)
1038 - the following LSCP commands now also support escape sequences for at
1039 least one of their text-based parameters (i.e. name, description):
1046 - returns verbose syntax errors (line and column where syntax error
1047 occured, the unexpected character and the actually expected, possible
1048 character(s), the latter only if less than 5 possibilities)
1049 - made sure that LSCP syntax is not affected by gigedit locale
1050 settings
1051 - bugfix regarding strings parameter lists: all comma separated lists
1052 of strings were treated as being one string containing commas
1053 (fixes #57)
1055 * Bug fixes:
1056 - fixed crash occurring on certain LSCP scripts (Bug 39)
1057 - another thread safety fix for lscp "load engine" and "set
1058 channel audio output device"
1059 - fixed a crash which occurs when reassigning the same engine
1060 on a sampler channel with connected MIDI device
1061 - fixed a crash which occurs when changing the number of ports of a MIDI
1062 device connected to a sampler channel to number less then or equal
1063 to the index of the port to which the sampler channel is connected.
1064 - The previous bindings were not been disconnected when altering
1065 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1066 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1067 - The active stream/voice count statistic was incorrect.
1068 - notification events were not been sent for some sampler
1069 channel changes
1070 - added default min and max values to restrict the number of allowed
1071 audio output channels and MIDI input ports
1072 - the connection to the PCM interface is now closed when destroying
1073 an audio output device
1074 - files with slash in their path or filename could not be loaded
1076 * test cases:
1077 - updated and fixed (haven't been touched in a while)
1079 Version 0.4.0 (24 November 2006)
1081 * packaging changes:
1082 - changed deprecated copyright attribute to license; added ldconfig
1083 to post-(un)install steps; added devel package for liblinuxsampler;
1084 to linuxsampler.spec (RPM)
1085 - install necessary development header files for allowing 3rd party
1086 applications to link against liblinuxsampler
1087 - liblinuxsampler's API documentation can be generated with 'make docs'
1088 (Doxygen required)
1089 - added benchmark to automatically detect the best triangle LFO
1090 implementation (currently either an integer math solution or a
1091 di-harmonic approximation), automatic detection can be overriden
1092 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1093 configure script argument though (mandatory for cross-compilation)
1094 - do not automatically pick optimized gcc flags if the user already
1095 provided some on his own (as CXXFLAGS)
1096 - added compile time option to disable processing of All-Notes-Off MIDI
1097 messages
1098 - added compile time options to allow disabling the various audio and
1099 MIDI drivers
1100 - fixed automatic GCC CPU switch detection on PPC
1101 (patch by Ebrahim Mayat)
1103 * Gigasampler format engine:
1104 - extensive synthesis optimization
1105 (reimplementation of EGs and LFO(s), removed synthesis parameter
1106 prerendering and the synthesis parameter matrix in general, splitting
1107 each audio fragment into subfragments now where each subfragment uses
1108 constant pitch and filter coefficients. The volume coefficient is
1109 linearly interpolated inside a subfragment, unless
1110 --disable-interpolate-volume is set.)
1111 - fine tuning of the EG modulation parameters
1112 - improved filter cutoff calculation by adding support for the
1113 following gig parameters: Cutoff freq (used when no cutoff
1114 controller is defined), Control invert, Minimum cutoff, Velocity
1115 curve and Velocity range. The keyboard tracking now scales
1116 cutoff frequency instead of resonance.
1117 - added support for gig parameter Resonance.
1118 - fixed bug in sysex handling (patch by Juan Linietsky)
1119 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1120 which can be overridden with --enable-global-attenuation
1121 - EG fixes: made the length of "attack hold" stage more
1122 accurate. Release stage can now start before attack stage
1123 ends. Cancel release didn't work when sustain was zero. Attack
1124 time now has a minimal value to prevent clicks.
1125 - fixed pitch changes larger than one octave
1126 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1127 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1128 all modes can be altered via standard GM messages, that is CC5 for
1129 altering portamento time, CC65 for enabling / disabling portamento
1130 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1131 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1132 parameter) and crossfade
1133 - added support for the "attenuation controller threshold" gig
1134 parameter
1135 - added smoothing of volume changes caused by control change
1136 messages
1137 - sample loop parameters are now taken from the DimensionRegion
1138 instead of the wave chunk
1139 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1140 not equal to a power of two
1141 - reimplementation of the filter algorithm. The new filter is more
1142 accurate and supports all gig filter types, including bandreject
1143 and lowpass turbo.
1144 - real support for 24 bit samples - samples are not truncated to
1145 16 bits anymore
1146 - support for aftertouch (channel pressure, not polyphonic
1147 aftertouch)
1148 - LFO1 behaviour fixed (dampening from max volume instead of
1149 amplifying from 0)
1151 * LSCP server:
1152 - fixed application exit on broken pipe error (fixes bug #20)
1153 - fixed the notification messages delay due to lack of
1154 network activity (fixes bug #26)
1155 - fixed parser bug which occured on space(s) within device parameters
1158 * audio driver:
1159 - added aRts audio output driver (by no means RT safe)
1161 * MIDI driver:
1162 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1163 messages several times instead of once
1164 - API extension for MIDI drivers which already supply exact time stamps
1165 for events (i.e. for offline rendering based MIDI drivers)
1166 - added checks for bad MIDI data
1168 * linuxsampler application:
1169 - show available sampler engine types on startup
1171 * general changes:
1172 - support for muting sampler channels and solo mode of the same, two new
1173 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1174 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1175 introduced for this, the behavior is the same like on a mixer console
1176 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1177 --enable-process-muted-channels which can be used to enable the
1178 processing of muted channels.
1179 - support for sostenuto pedal
1180 - support for monitoring the total number of active voices
1183 - fixed some memory management errors
1184 - fixed some concurrency problems that could lead to crashes when
1185 LSCP commands were executed
1186 - fixed crash when instrument loading failed previously on the same
1187 sampler channel (fixes bug #36)
1189 Version 0.3.3 (15 July 2005)
1191 * packaging changes:
1192 - fixed compilation with gcc 4.0
1194 * Gigasampler format engine:
1195 - LFO preprocessing was performed even though the respective LFO was
1196 disabled by the instrument patch (minor efficiency fix)
1197 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1198 for volume ramp downs in the same fragment (needed for current voice
1199 stealing implementation) then simply inform the user with a warning
1200 about possible click sounds and reduce the volume ramp down
1201 appropriately instead of cancelling the audio device connection
1203 Version 0.3.2 (24 June 2005)
1205 * packaging changes:
1206 - updated autotools build files to compile on OS X
1207 (conditional compilation of CoreMIDI and MidiShare drivers)
1208 - hand-crafted assembly optimization code can be disabled with
1209 './configure --disable-asm' (definitely not recommended)
1210 - fixed 'make dist' rule to include all necessary files
1211 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1212 (due to 'dist-bzip2' automake option)
1214 * Gigasampler format engine:
1215 - support for the gig parameters for "release velocity response" curves
1216 - fine tuning of the EGADSR envelope
1217 - volume of release triggered samples now depends on note-on velocity,
1218 note length and gig parameter "release trigger decay" instead of
1219 note-off velocity.
1220 - revised voice stealing
1221 (fixes crash and endless loop caused by voice stealing)
1222 - don't reset scale tuning on instrument or audio output device change
1223 - handle key group conflicts right at the beginning of each fragment
1224 instead of when the respective voice is actually launched
1225 (fixes undefined behavior if stolen voices belonged to a key group -
1226 this case was followed by a "killed voice survived" error message)
1227 - fixed minor issue with null/silence samples
1228 (those stole voices even though they don't need a voice at all which
1229 resulted in "voice stealing didn't work out" messages)
1230 - don't reset volume, pan, pitch and MIDI controller values on
1231 instrument or audio output device change
1233 * LSCP server:
1234 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1235 - fixed LSCP event "CHANNEL_INFO" notification
1236 (e.g. did not notify on volume changes or MIDI program change events)
1238 * linuxsampler application:
1239 - added command line parameters --lscp-addr and --lscp-port to override
1240 default IP address and port of LSCP server
1242 Version 0.3.1 (24 May 2005)
1244 * initial release
