* All engines: Increased ramp speed of volume smoother and pan smoother
  (while slow rate of crossfade smoother is preserved) to allow quick
  volume and pan changes by instrument scripts for instance.
* Bumped version (2.0.0.svn21).

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 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
28     (while slow rate of crossfade smoother is preserved) to allow quick
29     volume and pan changes by instrument scripts for instance.
30 persson 2837
31 schoenebeck 2866 * packaging changes:
32     - removed unnecessary dependency to libuuid
33     (originated by libgig's usage of it)
34 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
35     auto detect whether it (sh/c)ould output its messages in color.
36 schoenebeck 2866
37 schoenebeck 2871 * Real-time instrument scripts:
38     - Implemented scheduler for delayed MIDI events and for suspended scripts.
39     - Built-in script function "wait()": implemented support for function's
40     "duration-us" argument, thus scripts using this function are now
41     correctly resumed after the requested amount of microseconds.
42     - Built-in script function "play_note()": implemented support for
43     function's "duration-us" argument, thus notes triggered with this
44     argument are now correctly released after the requested amount of
45     microseconds.
46     - Fix: script events were not cleared when engine channel was reset,
47     potentially causing undefined behavior.
48     - Fixed crash which happened when trying to reference an undeclared
49     variable.
50 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
51     special value -1 for "duration-us" argument, which will cause the
52     triggered note to be released once the original note was released.
53 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
54     - Added new API method ScriptVM::syntaxHighlighting() which provides
55     a convenient syntax highlighting backend for external instrument
56     script editor applications.
57 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
58     - Extended parser issues to provide not only first line and first
59     column, but also last line and last column of issue (thus marking
60     the precise span of the issue within the source code).
61 schoenebeck 2902 - Reload script automatically after being modified by an instrument
62     editor.
63 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
64     like "on note end on".
65 schoenebeck 2931 - Implemented built-in script function "change_vol()".
66     - Implemented built-in script function "change_tune()".
67     - Implemented built-in script function "change_pan()".
68 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
69     - Implemented built-in script function "change_reso()".
70     - Implemented built-in script function "event_status()".
71     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
72     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
73     "event_status()" function.
74     - NKSP language: Added support for bitwise operators ".or.", ".and."
75     and ".not.".
76     - NKSP language scanner: Fixed IDs matching to require at least one
77     character (i.e. when matching function names or variable names).
78     - NKSP language scanner: disabled unusued rules.
79 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
80     be distinguished engine internally from "real" MIDI note on/off
81     events in order to avoid misbehaviors like hanging notes.
82 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
83     - Implemented built-in script variable "$NKSP_REAL_TIMER".
84     - Implemented built-in script variable "$NKSP_PERF_TIMER".
85     - Implemented built-in script variable "$ENGINE_UPTIME".
86 schoenebeck 2945 - Implemented built-in script function "inc()".
87     - Implemented built-in script function "dec()".
88     - NKSP language fix: division expressions were evaluated too often.
89     - NKSP language fix: string concatenation operator was right
90     associative instead of left (to right).
91 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
92     (i.e. "if end if").
93 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
94     - Implemented built-in script variable "$NI_CALLBACK_ID".
95     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
96     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
97     - Added support for read-only built-in variables (respectively
98     handled by the script parser).
99     - Added built-in script constant "$NI_CB_TYPE_INIT".
100     - Added built-in script constant "$NI_CB_TYPE_NOTE".
101     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
102     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
103 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
104 schoenebeck 2953 - Implemented built-in script function "change_attack()".
105     - Implemented built-in script function "change_decay()".
106     - Implemented built-in script function "change_release()".
107 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
108     synthesis parameter changes immediately in case the respective note
109     was triggered at the same time, instead of scheduling the parameter
110     change, especially because it would cause some parameter types's
111     changes either to be ramped (i.e. change_vol()) or other types even
112     to have not effect at all (i.e. change_attack()).

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

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

231     - bugfix: filter keyboard tracking was broken
232     - filter performance fix (an unnecessary copy was made of the
233     filter parameters in each sub fragment)
234     - handle special case when pan parameter in gig file has max or
235     min value
236 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
237     doesn't sound naturally with a drumkit

646     (fixes #208)
647 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like

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

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

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

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

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

768     in the instruments database
769     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
770 persson 1908 - work-around for missing fnmatch function on Windows to make
771     instrument database compilable
772 schoenebeck 1930 - added instrument database support on Windows
773     works with both standalone mode and VST plugin.
774     the instruments DB file is located in
775     %USERPROFILE%\.linuxsampler\instruments.db which allows different
776     databases for each windows user
777     if no DB is present it automatically creates the .linuxsampler subdir
778     and then creates an empty DB
779 persson 1943 - fixed recursive import, which was broken on Windows
780 iliev 1603
781 persson 1644 * Gigasampler format engine:
782     - fixed a memory leak that could happen when a channel was deleted
783     while notes were playing
784 persson 1646 - made it possible to load an instrument even if the audio thread
785     isn't running
786 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
787     enough for piano gigs with pedal noise samples
788 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
789     respective FX send MIDI controller was used
790 schoenebeck 1724 - added support for GM global device volume SysEx message
791 schoenebeck 1762 (can be selected at compile time to either apply globally to the
792     whole sampler [default] or only to the sampler channels that are
793     connected to the respective MIDI input port the SysEx message arrived
794     on)
795 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
796     sometimes wrongly killed in the same buffer, causing no sound to
797     be played
798 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
799     which is usally used to switch a part between chromatic sounds and
800     drumkit sounds (as opposed to their common default setting of MIDI
801     part 10 being a drumkit part and all other ones chromatic parts), in
802     LS however one can switch between the first 16 MIDI instrument maps
803     defined for the sampler
804 persson 1764 - made it possible to create multiple sample channels even if the
805     audio thread isn't running
806 persson 1844 - fixed crash when removing channel with active voices (#116)
807 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
808     un-cache the respective sample if it's really not used by any
809     sampler engine anymore
810     - re-cache samples in case they were changed by an instrument editor,
811     e.g. when a sample was added while playing (#82)
812 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
813     same time stamp as the voice's note-on event and occured both in the
814     same audio fragment cycle (fixes bug #112)
815 persson 1858 - added support for the "fine tune" and "pitch bend range"
816     instrument-level gig parameters
817     - fixed minor artifacts in pitch bend handling
818 schoenebeck 1860 - added support for GS Reset SysEx message
819 persson 1862 - allow gig files to use unlimited downward pitch shifting
820     - added a limit check for upward pitch shifting
821 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
822     note was silent
823 persson 1923 - fixed crash happening when a pitch bend event arrived at the
824     same time a new instrument was loading
825 persson 1644
826 schoenebeck 1687 * LSCP server:
827     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
828     react on MIDI data arriving on certain sampler channels (so far only
829     Note-On and Note-Off events are sent via this LSCP event)
830 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
831     react on MIDI data arriving on certain MIDI input devices (so far only
832     Note-On and Note-Off events are sent via this LSCP event)
833 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
834     SET DB_INSTRUMENT FILE_PATH
835 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
836     frontends to send MIDI messages to specific sampler channel
837     - added two additional fields to GET FILE INSTRUMENT INFO command -
838     KEY_BINDINGS and KEYSWITCH_BINDINGS
839 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
840     was incorrect
841 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
842 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
843     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
844     be triggered respectively
845     - added new LSCP command "SET STREAMS" to globally alter the maximum
846     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
847     which will be triggered respectively
848 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
849     a gigedit file dialog is opened)
850 iliev 1848 - close all connections when LSCPServer is deleted
851 iliev 1882 - hard close of all sockets on exit
852 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
853     driver
854 schoenebeck 1687
855 iliev 1761 * Bug fixes:
856     - fixed a crash which occurs when removing a sampler channel waiting
857     to start instrument loading after another channel
858 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
859     instrument loading in progress (bug #113)
860 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
861     instrument with PERSISTENT load mode
862 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
863     - fixed memory leaks when issuing the following LSCP commands:
864     GET AUDIO_OUTPUT_DRIVER INFO
865     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
866     GET MIDI_INPUT_DRIVER INFO
867     GET MIDI_INPUT_DRIVER_PARAMETER INFO
868     - fixed possible compilation error when sqlite is not present
869 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
870 iliev 1847 - fixed crash when changing the audio output device of a sampler
871     channel with loaded instrument and start playing notes
872 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
873 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
874     PowerPC, which probably could cause crashes on that platform
875 persson 1889 - fixed a memory management error which could cause a crash when a
876     plugin was unloaded
877 persson 1896 - bugfix: two private structs had the same name, which could cause
878     problems if the linker chose the wrong constructor
879 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
880     Windows
881 iliev 1761
882    
883 schoenebeck 1560 Version 0.5.1 (6 December 2007)
884 schoenebeck 1454
885     * packaging changes:
886     - added autoconf checks for pthread library
887     - added autoconf check for pthread bug found on certain NPTL-enabled
888     glibc versions (see Gentoo bug report #194076)
889 senoner 1502 - added autoconf checks for MS Windows
890 schoenebeck 1454
891 persson 1455 * general changes:
892     - bugfix: the thread used by an editor plugin didn't die when the
893     editor closed
894 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
895     out all the space. operator--() did not apply size_mask after
896     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
897     order to avoid problems with the _NonVolatileReader functions.
898     - bugfix: Stream.h: added a missing divide by BytesPerSample in
899     GetWriteSpace(). Since this function is currently only used in
900     the stream's qsort() compare function, it didn't trigger any
901     bugs.
902     - Resampler.h, Synthesizer.h: cubic interpolation now works in
903     24bit mode too. Faster method to read 24bit words on little
904     endian machines (x86): replaced 3 byte reads + shifts with a 1
905     unaligned 32bit read and shift
906     - experimental support for MS Windows (MIDI input via MME, AUDIO
907     output via ASIO)
908     - made handling of SIGINT signal (Ctrl-C) a bit more robust
909 iliev 1541 - support for monitoring the total number of active disk streams
910     (new LSCP commands: GET TOTAL_STREAM_COUNT,
911     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
912 persson 1455
913 senoner 1500 * AUDIO driver:
914 persson 1534 - added Windows ASIO low latency audio driver
915 senoner 1500
916 senoner 1485 * MIDI driver:
917 schoenebeck 1495 - added MME Windows MIDI driver
918 senoner 1485
919 schoenebeck 1471 * LSCP server:
920     - added support for Windows style path / filenames, however with
921     forward slash path separators instead of backslash
922     (i.e. "C:/foo/bar.gig")
923 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
924     apostrophes as well
925 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
926     "LIST FILE INSTRUMENTS <file>" and
927     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
928     about an arbitrary instrument file on the system where the sampler is
929     running on
930 schoenebeck 1471
931 schoenebeck 1424 Version 0.5.0 (15 October 2007)
932 schoenebeck 947
933 schoenebeck 1065 * packaging changes:
934 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
935     API header files anymore
936 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
937     the Doxygen API documentation (explicitly listed in Doxyfile.in)
938 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
939     capable to execute our autoconf environment, thus no need anymore
940     to maintain the compile time configuration file (osx/version.h) for
941     OSX manually (patch by Toshi Nagata)
942 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
943     parameters
944 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
945     C++ API header files, all implementation internal global definitions
946     are now in global_private.h
947     - atomic.h is not exposed to the C++ API anymore
948     - no need to include config.h anymore for using LS's API header files
949     - fixed warnings in API doc generation
950 schoenebeck 1065
951 schoenebeck 947 * general changes:
952     - replaced the old, confusing MIDI program change mechanism by a
953     flexible MIDI instrument mapper which allows to map arbitrary
954 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
955 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
956     loaded on the respective channel when such MIDI program change
957     messages arrive, beside that, each entry allows to define a life-time
958     strategy for the instrument, so the user can define whether the
959     instrument should i.e. be permanently loaded (to be able to switch
960     quickly among sounds) or i.e. loaded just on demand when the
961     respective program change arrives (to safe RAM space), as well as a
962     global volume factor for each entry, so the user can adjust the volume
963     dynamic of his mapped instrument collection without having to modify
964 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
965     MIDI instrument maps and assign each sampler channel individually
966     a certain map, so that i.e. separation of normal instruments and
967     drumkits is possible
968 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
969     MIDI instrument maps, MIDI instruments, FX sends, global volume.
970 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
971     due to a constant size RingBuffer FIFO which is now replaced by a
972     dynamic (unlimited) size std::list FIFO
973 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
974     output channels for being processed by external effect processors
975     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
976     controllers
977 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
978 iliev 1130 - Implemented new, improved notification system
979 schoenebeck 1149 - fixed compilation errors regarding OSX
980     (patch by Toshi Nagata)
981 iliev 1161 - implemented instruments database
982 iliev 1345 - added support for escape sequences to the instruments database
983 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
984     within the sampler's process (by using instrument editor plugins),
985     you'll notice the new "Registered instrument editors:" message on
986 schoenebeck 1407 startup, added a new LSCP command:
987     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
988 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
989     given sampler channel, the plugin path can be overridden at compile
990     time with ./configure --enable-plugin-dir=/some/dir
991 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
992     in the sampler's process to safely edit instruments while playing
993     without a crash (hopefully) by either suspending single regions
994     wherever possible or if unavoidable whole engine(s)
995 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
996     policy and priority on thread level, set a minimum stack size for
997     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
998     threads simply inherited properties of starting thread instead of
999     setting their own policy and priority
1000 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1001     main process did not wait for the stack trace process to finish
1002     its output
1003 persson 1248 - fixed some minor memory leaks
1004 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1005     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1006 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1007     register, to avoid relocations in the text segment at runtime)
1008 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1009 schoenebeck 947
1010     * MIDI driver:
1011     - dispatch bank select (MSB and LSB) messages
1012    
1013 schoenebeck 1049 * audio driver:
1014     - the ALSA audio output driver parameters now reflect the correct
1015     parameter value ranges for the respective selected sound card
1016     (patch by Till Wimmer, a bit fixed and extended)
1017    
1018 persson 951 * Gigasampler format engine:
1019     - if a filter is used and EG2 finishes before EG1, let the voice
1020     die when EG2 has finished (this fixes a problem with clicks and
1021     voice starvation for some gigs)
1022 persson 1038 - playback is no longer disabled during instrument loading
1023     - all notes playing on a channel that changes its instrument keep
1024     playing with the old instrument until they get a note off
1025     command
1026 persson 1039 - EG fix: a release value of zero could cause noises or crash
1027 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1028 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1029     above max sustain level, which means that there is a decay phase
1030     even if sustain is 100%
1031 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1032     noises or crashes
1033 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1034 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1035     supplied to the configure script (fixes #46)
1036 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1037     instead of a fix value
1038 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1039     127 (solo mode) only kill voices if the respective mode really
1040     changed
1041 persson 951
1042 schoenebeck 1244 * LSCP server:
1043     - fixed compile time error for old Bison versions
1044     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1045 schoenebeck 1245 - parser now supports extended ASCII character set
1046     (up to ASCII code 255, i.e. includes now umlauts and accents)
1047     - filename arguments in LSCP commands now allow to use escape
1048     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1049     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1050     code value like \xf2) (fixes bug #24)
1051 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1052     least one of their text-based parameters (i.e. name, description):
1053     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1054     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1055     "SET DB_INSTRUMENT_DIRECTORY NAME",
1056     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1057     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1058     "FIND DB_INSTRUMENT_DIRECTORIES"
1059 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1060     occured, the unexpected character and the actually expected, possible
1061     character(s), the latter only if less than 5 possibilities)
1062 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1063     settings
1064 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1065     of strings were treated as being one string containing commas
1066     (fixes #57)
1067 schoenebeck 1244
1068 iliev 959 * Bug fixes:
1069     - fixed crash occurring on certain LSCP scripts (Bug 39)
1070 persson 1038 - another thread safety fix for lscp "load engine" and "set
1071     channel audio output device"
1072 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1073     on a sampler channel with connected MIDI device
1074 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1075     device connected to a sampler channel to number less then or equal
1076     to the index of the port to which the sampler channel is connected.
1077 iliev 1296 - The previous bindings were not been disconnected when altering
1078     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1079     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1080 iliev 1297 - The active stream/voice count statistic was incorrect.
1081 iliev 1298 - notification events were not been sent for some sampler
1082     channel changes
1083 iliev 1305 - added default min and max values to restrict the number of allowed
1084     audio output channels and MIDI input ports
1085 iliev 1306 - the connection to the PCM interface is now closed when destroying
1086     an audio output device
1087 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1088 iliev 959
1089 schoenebeck 1221 * test cases:
1090     - updated and fixed (haven't been touched in a while)
1091    
1092 schoenebeck 937 Version 0.4.0 (24 November 2006)
1093 persson 696
1094 schoenebeck 697 * packaging changes:
1095 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1096     to post-(un)install steps; added devel package for liblinuxsampler;
1097     to linuxsampler.spec (RPM)
1098 schoenebeck 697 - install necessary development header files for allowing 3rd party
1099     applications to link against liblinuxsampler
1100     - liblinuxsampler's API documentation can be generated with 'make docs'
1101     (Doxygen required)
1102 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1103     implementation (currently either an integer math solution or a
1104     di-harmonic approximation), automatic detection can be overriden
1105     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1106     configure script argument though (mandatory for cross-compilation)
1107 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1108     provided some on his own (as CXXFLAGS)
1109 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1110     messages
1111 schoenebeck 852 - added compile time options to allow disabling the various audio and
1112     MIDI drivers
1113 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1114     (patch by Ebrahim Mayat)
1115 schoenebeck 697
1116 persson 696 * Gigasampler format engine:
1117 schoenebeck 738 - extensive synthesis optimization
1118     (reimplementation of EGs and LFO(s), removed synthesis parameter
1119     prerendering and the synthesis parameter matrix in general, splitting
1120     each audio fragment into subfragments now where each subfragment uses
1121 persson 830 constant pitch and filter coefficients. The volume coefficient is
1122     linearly interpolated inside a subfragment, unless
1123     --disable-interpolate-volume is set.)
1124 persson 696 - fine tuning of the EG modulation parameters
1125 persson 729 - improved filter cutoff calculation by adding support for the
1126     following gig parameters: Cutoff freq (used when no cutoff
1127     controller is defined), Control invert, Minimum cutoff, Velocity
1128 persson 791 curve and Velocity range. The keyboard tracking now scales
1129     cutoff frequency instead of resonance.
1130 persson 877 - added support for gig parameter Resonance.
1131 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1132 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1133     which can be overridden with --enable-global-attenuation
1134 persson 783 - EG fixes: made the length of "attack hold" stage more
1135     accurate. Release stage can now start before attack stage
1136 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1137     time now has a minimal value to prevent clicks.
1138 persson 799 - fixed pitch changes larger than one octave
1139 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1140     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1141     all modes can be altered via standard GM messages, that is CC5 for
1142     altering portamento time, CC65 for enabling / disabling portamento
1143     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1144 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1145     parameter) and crossfade
1146 persson 831 - added support for the "attenuation controller threshold" gig
1147     parameter
1148 persson 832 - added smoothing of volume changes caused by control change
1149     messages
1150 persson 865 - sample loop parameters are now taken from the DimensionRegion
1151     instead of the wave chunk
1152     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1153     not equal to a power of two
1154 persson 877 - reimplementation of the filter algorithm. The new filter is more
1155     accurate and supports all gig filter types, including bandreject
1156     and lowpass turbo.
1157 persson 903 - real support for 24 bit samples - samples are not truncated to
1158     16 bits anymore
1159     - support for aftertouch (channel pressure, not polyphonic
1160     aftertouch)
1161 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1162     amplifying from 0)
1163 persson 696
1164 schoenebeck 711 * LSCP server:
1165     - fixed application exit on broken pipe error (fixes bug #20)
1166 iliev 793 - fixed the notification messages delay due to lack of
1167     network activity (fixes bug #26)
1168 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1169     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1170 schoenebeck 711
1171 schoenebeck 838 * audio driver:
1172     - added aRts audio output driver (by no means RT safe)
1173    
1174 schoenebeck 775 * MIDI driver:
1175     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1176     messages several times instead of once
1177 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1178     for events (i.e. for offline rendering based MIDI drivers)
1179 persson 922 - added checks for bad MIDI data
1180 schoenebeck 775
1181 schoenebeck 900 * linuxsampler application:
1182     - show available sampler engine types on startup
1183    
1184 schoenebeck 705 * general changes:
1185     - support for muting sampler channels and solo mode of the same, two new
1186     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1187     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1188     introduced for this, the behavior is the same like on a mixer console
1189 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1190     --enable-process-muted-channels which can be used to enable the
1191     processing of muted channels.
1192 iliev 777 - support for sostenuto pedal
1193 iliev 779 - support for monitoring the total number of active voices
1194 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1195     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1196 persson 835 - fixed some memory management errors
1197 persson 841 - fixed some concurrency problems that could lead to crashes when
1198     LSCP commands were executed
1199 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1200     sampler channel (fixes bug #36)
1201 schoenebeck 705
1202 schoenebeck 692 Version 0.3.3 (15 July 2005)
1203 schoenebeck 686
1204     * packaging changes:
1205     - fixed compilation with gcc 4.0
1206    
1207 schoenebeck 687 * Gigasampler format engine:
1208     - LFO preprocessing was performed even though the respective LFO was
1209     disabled by the instrument patch (minor efficiency fix)
1210 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1211     for volume ramp downs in the same fragment (needed for current voice
1212     stealing implementation) then simply inform the user with a warning
1213     about possible click sounds and reduce the volume ramp down
1214     appropriately instead of cancelling the audio device connection
1215 schoenebeck 687
1216 schoenebeck 677 Version 0.3.2 (24 June 2005)
1217 schoenebeck 609
1218     * packaging changes:
1219     - updated autotools build files to compile on OS X
1220     (conditional compilation of CoreMIDI and MidiShare drivers)
1221 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1222     './configure --disable-asm' (definitely not recommended)
1223 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1224     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1225     (due to 'dist-bzip2' automake option)
1226 schoenebeck 649
1227     * Gigasampler format engine:
1228     - support for the gig parameters for "release velocity response" curves
1229     - fine tuning of the EGADSR envelope
1230     - volume of release triggered samples now depends on note-on velocity,
1231     note length and gig parameter "release trigger decay" instead of
1232     note-off velocity.
1233 schoenebeck 663 - revised voice stealing
1234     (fixes crash and endless loop caused by voice stealing)
1235 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1236 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1237     instead of when the respective voice is actually launched
1238     (fixes undefined behavior if stolen voices belonged to a key group -
1239     this case was followed by a "killed voice survived" error message)
1240 schoenebeck 669 - fixed minor issue with null/silence samples
1241     (those stole voices even though they don't need a voice at all which
1242     resulted in "voice stealing didn't work out" messages)
1243 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1244     instrument or audio output device change
1245 schoenebeck 654
1246 schoenebeck 620 * LSCP server:
1247 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1248 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1249 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1250 schoenebeck 609
1251 schoenebeck 668 * linuxsampler application:
1252     - added command line parameters --lscp-addr and --lscp-port to override
1253     default IP address and port of LSCP server
1254    
1255 schoenebeck 579 Version 0.3.1 (24 May 2005)
1256    
1257     * initial release
