* NKSP: Fixed all change_*() built-in script functions to apply their
  synthesis parameter changes immediately in case the respective note
  was triggered at the same time, instead of scheduling the parameter
  change, especially because it would cause some parameter types's
  changes either to be ramped (i.e. change_vol()) or other types even
  to have not effect at all (i.e. change_attack()).
* Bumped version (2.0.0.svn20).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5    
6 persson 2837 * general changes:
7     - fixed printf type errors (mostly in debug messages)
8 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
9 schoenebeck 2871 - 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 schoenebeck 2879 - 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 schoenebeck 2927 - 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.
27 persson 2837
28 schoenebeck 2866 * packaging changes:
29     - removed unnecessary dependency to libuuid
30     (originated by libgig's usage of it)
31 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32     auto detect whether it (sh/c)ould output its messages in color.
33 schoenebeck 2866
34 schoenebeck 2871 * 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 schoenebeck 2879 - 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 schoenebeck 2885 - 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 schoenebeck 2889 - 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 schoenebeck 2902 - Reload script automatically after being modified by an instrument
59     editor.
60 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
61     like "on note end on".
62 schoenebeck 2931 - Implemented built-in script function "change_vol()".
63     - Implemented built-in script function "change_tune()".
64     - Implemented built-in script function "change_pan()".
65 schoenebeck 2935 - 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 schoenebeck 2938 - 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 schoenebeck 2942 - 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 schoenebeck 2945 - 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 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
89     (i.e. "if end if").
90 schoenebeck 2948 - 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".
100 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
101 schoenebeck 2953 - Implemented built-in script function "change_attack()".
102     - Implemented built-in script function "change_decay()".
103     - Implemented built-in script function "change_release()".
104 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
105     synthesis parameter changes immediately in case the respective note
106     was triggered at the same time, instead of scheduling the parameter
107     change, especially because it would cause some parameter types's
108     changes either to be ramped (i.e. change_vol()) or other types even
109     to have not effect at all (i.e. change_attack()).

150 persson 2382
151 persson 2086 * general changes:
152 iliev 2012 - Refactoring: moved the independent code from
153     the Gigasampler format engine to base classes
154 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
155     respective profiling code is currently broken
156 schoenebeck 2053 - Introduced support for optional environment variable
157     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
158     where the sampler shall look for instrument editor plugins
159     (patch by Luis Garrido, slightly modified).
160 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
161     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
162     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
163     note (in this implementation of the sampler its simply hard routed to
164     the 1st effect send of the sampler channel, no matter what the actual
165     effect type is)
166     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
167     note (in this implementation of the sampler its simply hard routed to
168     the 2nd effect send of the sampler channel, no matter what the actual
169     effect type is)
170 schoenebeck 2124 - implemented support for internal LADSPA effects
171 schoenebeck 2140 - raised limit of program change queue from 100 to 512
172     (as suggested by Alex Stone)

174 iliev 2296 - experimental support for per voice equalization
175 iliev 2306 - added command line option --exec-after-init
176 schoenebeck 2330 - Introduced new C++ API method:
177     EngineChannel::InstrumentFileName(int index)
178     allowing to retrieve the whole list of files used for the loaded
179     instrument on an engine channel (a.k.a. part). Some GigaStudio
180     instruments for example are splitted over several files like
181     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
182 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
183     - Added new C++ API method Sampler::GetGlobalMaxStreams().
184     - Added new C++ API method Sampler::SetGlobalMaxVoices().
185     - Added new C++ API method Sampler::SetGlobalMaxStreams().
186 schoenebeck 2377 - Various "const" and "restrict" optimizations.
187 persson 2382 - all engines: add pan CC value to instrument pan parameter before
188     applying panning, instead of using two separate pan functions in
189     series (#182)
190 persson 2427 - added a lock guard class for exception safe mutex handling and
191     used it everywhere appropriate
192 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
193     - Exposed scale tuning to C++ API (along to the already existing standard
194     SysEx way).
195 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
196     and broken for ppc64. (Seq_cst loads and stores are actually not
197     used in LS, so the bug wasn't noticable.)
198     - lsatomic.h: added ARMv7 support
199 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
200     added various new C++ methods for this new feature / design change, old
201     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
202     as deprecated but are still there and should provide full behavior
203     backward compatibility).
204     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
205     unsafe and caused compilation error with clang 2.x).
206 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
207 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
208     sampler from the command line by providing LSCP aware features.
209 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
210     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
211     - VirtualMidiDevice: Added support for pitch bend.
212 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
213     polyphonic key pressure events (so far polyphonic pressure was not
214     supported at all, and channel pressure was rerouted as CC128 but not
215     used so far).
216 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
217     code is shared by all sampler engine implemementations, however only the
218     gig file format currently provides support for storing instrument scripts
219     (as LinuxSampler extension to the original GigaStudio 4 format).
220 iliev 2012
221 persson 2043 * Gigasampler format engine:
222     - implemented the "round robin keyboard" dimension
223     - fixed round robin and random dimensions for cases when number of

230     filter parameters in each sub fragment)
231     - handle special case when pan parameter in gig file has max or
232     min value
233 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
234     doesn't sound naturally with a drumkit

643     (fixes #208)
644 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
645     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
646     practically irrelevant, however it caused problems with the new LSCP

697 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
698 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
699 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
700     be switched on by command line option "--stacktrace" (the automatic
701     stacktrace mechanism seems to be broken on most systems at the moment)
702 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
703     a pointer to the launched InstrumentEditor object
704 schoenebeck 1876 - added optional 3rd party user data parameter for following
705     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

709     model more strictly
710 persson 1895 - fixes for using large audio device buffers
711 persson 1951 - Windows: add the installation directory to the DLL search path

714 schoenebeck 2509 - updated linuxsampler man page
715 schoenebeck 1601
716 schoenebeck 1599 * audio driver:
717     - removed the nonsense audio channel constraint (which was hard coded to
718     max. 100 audio channels) for most audio drivers
719 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
720     opposed to the LSCP specs
721 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
722     reflected the wrong value
723 persson 1644 - fixed a memory management bug in ASIO driver
724 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
725 persson 1777 - JACK: use jack_client_open instead of the deprecated
726 persson 1748 jack_client_new
727 iliev 1829 - added (experimental) CoreAudio driver
728 persson 1888 - applied old fixes to the ASIO driver that were included in the
729     previous binary release but accidentally never committed to CVS
730     (fixes #117)
731 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
732     win64)
733 persson 1895 - VST: added support for sample rate and buffer size changes
734     - VST: close editor (Fantasia) when the VST is removed

739     stereo
740 persson 1922 - added channel routing, fxsends and midi maps to the settings
741     stored in the plugin state
742 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
743     AudioChannel::CopyTo() methods using GCC vector exensions
744     (if available)
745 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
746     exception when getting parameters from a disconnected device
747 schoenebeck 1599
748 persson 1651 * MIDI driver:
749     - added JACK MIDI driver
750 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
751     want to (mis)use it for some purpose ("fixed" in all current MIDI
752     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
753 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
754 persson 1887 CoreMidi or AU
755 persson 1889 - fixed mingw-w64 compilation error in MME driver
756 persson 1924 - made program change handling in MIDI thread real-time safe by
757     moving the logic to a non-RT thread

759 persson 1651
760 schoenebeck 1604 * instruments database:
761 iliev 1603 - avoid time consuming samples scanning when adding instruments
762     to the instruments database
763 iliev 1727 - added support for handling lost files in the instruments database

765     in the instruments database
766     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
767 persson 1908 - work-around for missing fnmatch function on Windows to make
768     instrument database compilable
769 schoenebeck 1930 - added instrument database support on Windows
770     works with both standalone mode and VST plugin.
771     the instruments DB file is located in
772     %USERPROFILE%\.linuxsampler\instruments.db which allows different
773     databases for each windows user
774     if no DB is present it automatically creates the .linuxsampler subdir
775     and then creates an empty DB
776 persson 1943 - fixed recursive import, which was broken on Windows
777 iliev 1603
778 persson 1644 * Gigasampler format engine:
779     - fixed a memory leak that could happen when a channel was deleted
780     while notes were playing
781 persson 1646 - made it possible to load an instrument even if the audio thread
782     isn't running
783 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
784     enough for piano gigs with pedal noise samples
785 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
786     respective FX send MIDI controller was used
787 schoenebeck 1724 - added support for GM global device volume SysEx message
788 schoenebeck 1762 (can be selected at compile time to either apply globally to the
789     whole sampler [default] or only to the sampler channels that are
790     connected to the respective MIDI input port the SysEx message arrived
791     on)
792 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
793     sometimes wrongly killed in the same buffer, causing no sound to
794     be played
795 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
796     which is usally used to switch a part between chromatic sounds and
797     drumkit sounds (as opposed to their common default setting of MIDI
798     part 10 being a drumkit part and all other ones chromatic parts), in
799     LS however one can switch between the first 16 MIDI instrument maps
800     defined for the sampler
801 persson 1764 - made it possible to create multiple sample channels even if the
802     audio thread isn't running
803 persson 1844 - fixed crash when removing channel with active voices (#116)
804 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
805     un-cache the respective sample if it's really not used by any
806     sampler engine anymore
807     - re-cache samples in case they were changed by an instrument editor,
808     e.g. when a sample was added while playing (#82)
809 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
810     same time stamp as the voice's note-on event and occured both in the
811     same audio fragment cycle (fixes bug #112)
812 persson 1858 - added support for the "fine tune" and "pitch bend range"
813     instrument-level gig parameters
814     - fixed minor artifacts in pitch bend handling
815 schoenebeck 1860 - added support for GS Reset SysEx message
816 persson 1862 - allow gig files to use unlimited downward pitch shifting
817     - added a limit check for upward pitch shifting
818 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
819     note was silent
820 persson 1923 - fixed crash happening when a pitch bend event arrived at the
821     same time a new instrument was loading
822 persson 1644
823 schoenebeck 1687 * LSCP server:
824     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
825     react on MIDI data arriving on certain sampler channels (so far only
826     Note-On and Note-Off events are sent via this LSCP event)
827 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
828     react on MIDI data arriving on certain MIDI input devices (so far only
829     Note-On and Note-Off events are sent via this LSCP event)
830 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
831     SET DB_INSTRUMENT FILE_PATH
832 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
833     frontends to send MIDI messages to specific sampler channel
834     - added two additional fields to GET FILE INSTRUMENT INFO command -
835     KEY_BINDINGS and KEYSWITCH_BINDINGS
836 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
837     was incorrect
838 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
839 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
840     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
841     be triggered respectively
842     - added new LSCP command "SET STREAMS" to globally alter the maximum
843     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
844     which will be triggered respectively
845 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
846     a gigedit file dialog is opened)
847 iliev 1848 - close all connections when LSCPServer is deleted
848 iliev 1882 - hard close of all sockets on exit
849 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
850     driver
851 schoenebeck 1687
852 iliev 1761 * Bug fixes:
853     - fixed a crash which occurs when removing a sampler channel waiting
854     to start instrument loading after another channel
855 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
856     instrument loading in progress (bug #113)
857 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
858     instrument with PERSISTENT load mode
859 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
860     - fixed memory leaks when issuing the following LSCP commands:
861     GET AUDIO_OUTPUT_DRIVER INFO
862     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
863     GET MIDI_INPUT_DRIVER INFO
864     GET MIDI_INPUT_DRIVER_PARAMETER INFO
865     - fixed possible compilation error when sqlite is not present
866 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
867 iliev 1847 - fixed crash when changing the audio output device of a sampler
868     channel with loaded instrument and start playing notes
869 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
870 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
871     PowerPC, which probably could cause crashes on that platform
872 persson 1889 - fixed a memory management error which could cause a crash when a
873     plugin was unloaded
874 persson 1896 - bugfix: two private structs had the same name, which could cause
875     problems if the linker chose the wrong constructor
876 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
877     Windows
878 iliev 1761
879    
880 schoenebeck 1560 Version 0.5.1 (6 December 2007)
881 schoenebeck 1454
882     * packaging changes:
883     - added autoconf checks for pthread library
884     - added autoconf check for pthread bug found on certain NPTL-enabled
885     glibc versions (see Gentoo bug report #194076)
886 senoner 1502 - added autoconf checks for MS Windows
887 schoenebeck 1454
888 persson 1455 * general changes:
889     - bugfix: the thread used by an editor plugin didn't die when the
890     editor closed
891 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
892     out all the space. operator--() did not apply size_mask after
893     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
894     order to avoid problems with the _NonVolatileReader functions.
895     - bugfix: Stream.h: added a missing divide by BytesPerSample in
896     GetWriteSpace(). Since this function is currently only used in
897     the stream's qsort() compare function, it didn't trigger any
898     bugs.
899     - Resampler.h, Synthesizer.h: cubic interpolation now works in
900     24bit mode too. Faster method to read 24bit words on little
901     endian machines (x86): replaced 3 byte reads + shifts with a 1
902     unaligned 32bit read and shift
903     - experimental support for MS Windows (MIDI input via MME, AUDIO
904     output via ASIO)
905     - made handling of SIGINT signal (Ctrl-C) a bit more robust
906 iliev 1541 - support for monitoring the total number of active disk streams
907     (new LSCP commands: GET TOTAL_STREAM_COUNT,
908     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
909 persson 1455
910 senoner 1500 * AUDIO driver:
911 persson 1534 - added Windows ASIO low latency audio driver
912 senoner 1500
913 senoner 1485 * MIDI driver:
914 schoenebeck 1495 - added MME Windows MIDI driver
915 senoner 1485
916 schoenebeck 1471 * LSCP server:
917     - added support for Windows style path / filenames, however with
918     forward slash path separators instead of backslash
919     (i.e. "C:/foo/bar.gig")
920 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
921     apostrophes as well
922 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
923     "LIST FILE INSTRUMENTS <file>" and
924     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
925     about an arbitrary instrument file on the system where the sampler is
926     running on
927 schoenebeck 1471
928 schoenebeck 1424 Version 0.5.0 (15 October 2007)
929 schoenebeck 947
930 schoenebeck 1065 * packaging changes:
931 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
932     API header files anymore
933 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
934     the Doxygen API documentation (explicitly listed in Doxyfile.in)
935 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
936     capable to execute our autoconf environment, thus no need anymore
937     to maintain the compile time configuration file (osx/version.h) for
938     OSX manually (patch by Toshi Nagata)
939 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
940     parameters
941 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
942     C++ API header files, all implementation internal global definitions
943     are now in global_private.h
944     - atomic.h is not exposed to the C++ API anymore
945     - no need to include config.h anymore for using LS's API header files
946     - fixed warnings in API doc generation
947 schoenebeck 1065
948 schoenebeck 947 * general changes:
949     - replaced the old, confusing MIDI program change mechanism by a
950     flexible MIDI instrument mapper which allows to map arbitrary
951 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
952 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
953     loaded on the respective channel when such MIDI program change
954     messages arrive, beside that, each entry allows to define a life-time
955     strategy for the instrument, so the user can define whether the
956     instrument should i.e. be permanently loaded (to be able to switch
957     quickly among sounds) or i.e. loaded just on demand when the
958     respective program change arrives (to safe RAM space), as well as a
959     global volume factor for each entry, so the user can adjust the volume
960     dynamic of his mapped instrument collection without having to modify
961 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
962     MIDI instrument maps and assign each sampler channel individually
963     a certain map, so that i.e. separation of normal instruments and
964     drumkits is possible
965 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
966     MIDI instrument maps, MIDI instruments, FX sends, global volume.
967 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
968     due to a constant size RingBuffer FIFO which is now replaced by a
969     dynamic (unlimited) size std::list FIFO
970 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
971     output channels for being processed by external effect processors
972     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
973     controllers
974 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
975 iliev 1130 - Implemented new, improved notification system
976 schoenebeck 1149 - fixed compilation errors regarding OSX
977     (patch by Toshi Nagata)
978 iliev 1161 - implemented instruments database
979 iliev 1345 - added support for escape sequences to the instruments database
980 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
981     within the sampler's process (by using instrument editor plugins),
982     you'll notice the new "Registered instrument editors:" message on
983 schoenebeck 1407 startup, added a new LSCP command:
984     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
985 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
986     given sampler channel, the plugin path can be overridden at compile
987     time with ./configure --enable-plugin-dir=/some/dir
988 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
989     in the sampler's process to safely edit instruments while playing
990     without a crash (hopefully) by either suspending single regions
991     wherever possible or if unavoidable whole engine(s)
992 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
993     policy and priority on thread level, set a minimum stack size for
994     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
995     threads simply inherited properties of starting thread instead of
996     setting their own policy and priority
997 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
998     main process did not wait for the stack trace process to finish
999     its output
1000 persson 1248 - fixed some minor memory leaks
1001 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1002     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1003 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1004     register, to avoid relocations in the text segment at runtime)
1005 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1006 schoenebeck 947
1007     * MIDI driver:
1008     - dispatch bank select (MSB and LSB) messages
1009    
1010 schoenebeck 1049 * audio driver:
1011     - the ALSA audio output driver parameters now reflect the correct
1012     parameter value ranges for the respective selected sound card
1013     (patch by Till Wimmer, a bit fixed and extended)
1014    
1015 persson 951 * Gigasampler format engine:
1016     - if a filter is used and EG2 finishes before EG1, let the voice
1017     die when EG2 has finished (this fixes a problem with clicks and
1018     voice starvation for some gigs)
1019 persson 1038 - playback is no longer disabled during instrument loading
1020     - all notes playing on a channel that changes its instrument keep
1021     playing with the old instrument until they get a note off
1022     command
1023 persson 1039 - EG fix: a release value of zero could cause noises or crash
1024 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1025 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1026     above max sustain level, which means that there is a decay phase
1027     even if sustain is 100%
1028 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1029     noises or crashes
1030 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1031 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1032     supplied to the configure script (fixes #46)
1033 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1034     instead of a fix value
1035 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1036     127 (solo mode) only kill voices if the respective mode really
1037     changed
1038 persson 951
1039 schoenebeck 1244 * LSCP server:
1040     - fixed compile time error for old Bison versions
1041     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1042 schoenebeck 1245 - parser now supports extended ASCII character set
1043     (up to ASCII code 255, i.e. includes now umlauts and accents)
1044     - filename arguments in LSCP commands now allow to use escape
1045     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1046     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1047     code value like \xf2) (fixes bug #24)
1048 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1049     least one of their text-based parameters (i.e. name, description):
1050     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1051     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1052     "SET DB_INSTRUMENT_DIRECTORY NAME",
1053     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1054     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1055     "FIND DB_INSTRUMENT_DIRECTORIES"
1056 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1057     occured, the unexpected character and the actually expected, possible
1058     character(s), the latter only if less than 5 possibilities)
1059 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1060     settings
1061 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1062     of strings were treated as being one string containing commas
1063     (fixes #57)
1064 schoenebeck 1244
1065 iliev 959 * Bug fixes:
1066     - fixed crash occurring on certain LSCP scripts (Bug 39)
1067 persson 1038 - another thread safety fix for lscp "load engine" and "set
1068     channel audio output device"
1069 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1070     on a sampler channel with connected MIDI device
1071 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1072     device connected to a sampler channel to number less then or equal
1073     to the index of the port to which the sampler channel is connected.
1074 iliev 1296 - The previous bindings were not been disconnected when altering
1075     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1076     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1077 iliev 1297 - The active stream/voice count statistic was incorrect.
1078 iliev 1298 - notification events were not been sent for some sampler
1079     channel changes
1080 iliev 1305 - added default min and max values to restrict the number of allowed
1081     audio output channels and MIDI input ports
1082 iliev 1306 - the connection to the PCM interface is now closed when destroying
1083     an audio output device
1084 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1085 iliev 959
1086 schoenebeck 1221 * test cases:
1087     - updated and fixed (haven't been touched in a while)
1088    
1089 schoenebeck 937 Version 0.4.0 (24 November 2006)
1090 persson 696
1091 schoenebeck 697 * packaging changes:
1092 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1093     to post-(un)install steps; added devel package for liblinuxsampler;
1094     to linuxsampler.spec (RPM)
1095 schoenebeck 697 - install necessary development header files for allowing 3rd party
1096     applications to link against liblinuxsampler
1097     - liblinuxsampler's API documentation can be generated with 'make docs'
1098     (Doxygen required)
1099 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1100     implementation (currently either an integer math solution or a
1101     di-harmonic approximation), automatic detection can be overriden
1102     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1103     configure script argument though (mandatory for cross-compilation)
1104 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1105     provided some on his own (as CXXFLAGS)
1106 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1107     messages
1108 schoenebeck 852 - added compile time options to allow disabling the various audio and
1109     MIDI drivers
1110 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1111     (patch by Ebrahim Mayat)
1112 schoenebeck 697
1113 persson 696 * Gigasampler format engine:
1114 schoenebeck 738 - extensive synthesis optimization
1115     (reimplementation of EGs and LFO(s), removed synthesis parameter
1116     prerendering and the synthesis parameter matrix in general, splitting
1117     each audio fragment into subfragments now where each subfragment uses
1118 persson 830 constant pitch and filter coefficients. The volume coefficient is
1119     linearly interpolated inside a subfragment, unless
1120     --disable-interpolate-volume is set.)
1121 persson 696 - fine tuning of the EG modulation parameters
1122 persson 729 - improved filter cutoff calculation by adding support for the
1123     following gig parameters: Cutoff freq (used when no cutoff
1124     controller is defined), Control invert, Minimum cutoff, Velocity
1125 persson 791 curve and Velocity range. The keyboard tracking now scales
1126     cutoff frequency instead of resonance.
1127 persson 877 - added support for gig parameter Resonance.
1128 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1129 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1130     which can be overridden with --enable-global-attenuation
1131 persson 783 - EG fixes: made the length of "attack hold" stage more
1132     accurate. Release stage can now start before attack stage
1133 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1134     time now has a minimal value to prevent clicks.
1135 persson 799 - fixed pitch changes larger than one octave
1136 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1137     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1138     all modes can be altered via standard GM messages, that is CC5 for
1139     altering portamento time, CC65 for enabling / disabling portamento
1140     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1141 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1142     parameter) and crossfade
1143 persson 831 - added support for the "attenuation controller threshold" gig
1144     parameter
1145 persson 832 - added smoothing of volume changes caused by control change
1146     messages
1147 persson 865 - sample loop parameters are now taken from the DimensionRegion
1148     instead of the wave chunk
1149     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1150     not equal to a power of two
1151 persson 877 - reimplementation of the filter algorithm. The new filter is more
1152     accurate and supports all gig filter types, including bandreject
1153     and lowpass turbo.
1154 persson 903 - real support for 24 bit samples - samples are not truncated to
1155     16 bits anymore
1156     - support for aftertouch (channel pressure, not polyphonic
1157     aftertouch)
1158 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1159     amplifying from 0)
1160 persson 696
1161 schoenebeck 711 * LSCP server:
1162     - fixed application exit on broken pipe error (fixes bug #20)
1163 iliev 793 - fixed the notification messages delay due to lack of
1164     network activity (fixes bug #26)
1165 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1166     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1167 schoenebeck 711
1168 schoenebeck 838 * audio driver:
1169     - added aRts audio output driver (by no means RT safe)
1170    
1171 schoenebeck 775 * MIDI driver:
1172     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1173     messages several times instead of once
1174 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1175     for events (i.e. for offline rendering based MIDI drivers)
1176 persson 922 - added checks for bad MIDI data
1177 schoenebeck 775
1178 schoenebeck 900 * linuxsampler application:
1179     - show available sampler engine types on startup
1180    
1181 schoenebeck 705 * general changes:
1182     - support for muting sampler channels and solo mode of the same, two new
1183     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1184     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1185     introduced for this, the behavior is the same like on a mixer console
1186 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1187     --enable-process-muted-channels which can be used to enable the
1188     processing of muted channels.
1189 iliev 777 - support for sostenuto pedal
1190 iliev 779 - support for monitoring the total number of active voices
1191 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1192     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1193 persson 835 - fixed some memory management errors
1194 persson 841 - fixed some concurrency problems that could lead to crashes when
1195     LSCP commands were executed
1196 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1197     sampler channel (fixes bug #36)
1198 schoenebeck 705
1199 schoenebeck 692 Version 0.3.3 (15 July 2005)
1200 schoenebeck 686
1201     * packaging changes:
1202     - fixed compilation with gcc 4.0
1203    
1204 schoenebeck 687 * Gigasampler format engine:
1205     - LFO preprocessing was performed even though the respective LFO was
1206     disabled by the instrument patch (minor efficiency fix)
1207 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1208     for volume ramp downs in the same fragment (needed for current voice
1209     stealing implementation) then simply inform the user with a warning
1210     about possible click sounds and reduce the volume ramp down
1211     appropriately instead of cancelling the audio device connection
1212 schoenebeck 687
1213 schoenebeck 677 Version 0.3.2 (24 June 2005)
1214 schoenebeck 609
1215     * packaging changes:
1216     - updated autotools build files to compile on OS X
1217     (conditional compilation of CoreMIDI and MidiShare drivers)
1218 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1219     './configure --disable-asm' (definitely not recommended)
1220 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1221     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1222     (due to 'dist-bzip2' automake option)
1223 schoenebeck 649
1224     * Gigasampler format engine:
1225     - support for the gig parameters for "release velocity response" curves
1226     - fine tuning of the EGADSR envelope
1227     - volume of release triggered samples now depends on note-on velocity,
1228     note length and gig parameter "release trigger decay" instead of
1229     note-off velocity.
1230 schoenebeck 663 - revised voice stealing
1231     (fixes crash and endless loop caused by voice stealing)
1232 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1233 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1234     instead of when the respective voice is actually launched
1235     (fixes undefined behavior if stolen voices belonged to a key group -
1236     this case was followed by a "killed voice survived" error message)
1237 schoenebeck 669 - fixed minor issue with null/silence samples
1238     (those stole voices even though they don't need a voice at all which
1239     resulted in "voice stealing didn't work out" messages)
1240 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1241     instrument or audio output device change
1242 schoenebeck 654
1243 schoenebeck 620 * LSCP server:
1244 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1245 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1246 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1247 schoenebeck 609
1248 schoenebeck 668 * linuxsampler application:
1249     - added command line parameters --lscp-addr and --lscp-port to override
1250     default IP address and port of LSCP server
1251    
1252 schoenebeck 579 Version 0.3.1 (24 May 2005)
1253    
1254     * initial release
