* All engines: Implemented scheduler for delayed MIDI events and for
  suspended real-time instrument scripts.
* Real-Time instrument scripts: Implemented support for built-in "wait()"
  function's "duration-us" argument, thus scripts using this function are
  now correctly resumed after the requested amount of microseconds.
* Real-Time instrument scripts: Implemented support for built-in
  "play_note()" function's "duration-us" argument, thus notes triggered
  with this argument are now correctly released after the requested amount
  of microseconds.
* Real-Time instrument scripts: Fixed crash which happened when trying to
  reference an undeclared script variable.
* Real-Time instrument scripts: Script events were not cleared when
  engine channel was reset, potentially causing undefined behavior.
* All engines: Attempt to partly fix resetting engine channels vs.
  resetting engine, an overall cleanup of the Reset*(),
  ConnectAudioDevice(), DisconnectAudioDevice() API methods would still be
  desirable though, because the current situation is still inconsistent
  and error prone.
* Bumped version (2.0.0.svn2).

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 persson 2837
20 schoenebeck 2866 * packaging changes:
21     - removed unnecessary dependency to libuuid
22     (originated by libgig's usage of it)
23    
24 schoenebeck 2871 * Real-time instrument scripts:
25     - Implemented scheduler for delayed MIDI events and for suspended scripts.
26     - Built-in script function "wait()": implemented support for function's
27     "duration-us" argument, thus scripts using this function are now
28     correctly resumed after the requested amount of microseconds.
29     - Built-in script function "play_note()": implemented support for
30     function's "duration-us" argument, thus notes triggered with this
31     argument are now correctly released after the requested amount of
32     microseconds.
33     - Fix: script events were not cleared when engine channel was reset,
34     potentially causing undefined behavior.
35     - Fixed crash which happened when trying to reference an undeclared
36     variable.

76     in order to get rid of warnings from automake 1.14
77 persson 2382
78 persson 2086 * general changes:
79 iliev 2012 - Refactoring: moved the independent code from
80     the Gigasampler format engine to base classes
81 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
82     respective profiling code is currently broken
83 schoenebeck 2053 - Introduced support for optional environment variable
84     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
85     where the sampler shall look for instrument editor plugins
86     (patch by Luis Garrido, slightly modified).
87 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
88     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
89     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
90     note (in this implementation of the sampler its simply hard routed to
91     the 1st effect send of the sampler channel, no matter what the actual
92     effect type is)
93     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
94     note (in this implementation of the sampler its simply hard routed to
95     the 2nd effect send of the sampler channel, no matter what the actual
96     effect type is)
97 schoenebeck 2124 - implemented support for internal LADSPA effects
98 schoenebeck 2140 - raised limit of program change queue from 100 to 512
99     (as suggested by Alex Stone)
100 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
101 iliev 2296 - experimental support for per voice equalization
102 iliev 2306 - added command line option --exec-after-init
103 schoenebeck 2330 - Introduced new C++ API method:
104     EngineChannel::InstrumentFileName(int index)
105     allowing to retrieve the whole list of files used for the loaded
106     instrument on an engine channel (a.k.a. part). Some GigaStudio
107     instruments for example are splitted over several files like
108     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
109 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
110     - Added new C++ API method Sampler::GetGlobalMaxStreams().
111     - Added new C++ API method Sampler::SetGlobalMaxVoices().
112     - Added new C++ API method Sampler::SetGlobalMaxStreams().
113 schoenebeck 2377 - Various "const" and "restrict" optimizations.
114 persson 2382 - all engines: add pan CC value to instrument pan parameter before
115     applying panning, instead of using two separate pan functions in
116     series (#182)
117 persson 2427 - added a lock guard class for exception safe mutex handling and
118     used it everywhere appropriate
119 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
120     - Exposed scale tuning to C++ API (along to the already existing standard
121     SysEx way).
122 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
123     and broken for ppc64. (Seq_cst loads and stores are actually not
124     used in LS, so the bug wasn't noticable.)
125     - lsatomic.h: added ARMv7 support
126 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
127     added various new C++ methods for this new feature / design change, old
128     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
129     as deprecated but are still there and should provide full behavior
130     backward compatibility).
131     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
132     unsafe and caused compilation error with clang 2.x).
133 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
134 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
135     sampler from the command line by providing LSCP aware features.
136 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
137     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
138     - VirtualMidiDevice: Added support for pitch bend.
139 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
140     polyphonic key pressure events (so far polyphonic pressure was not
141     supported at all, and channel pressure was rerouted as CC128 but not
142     used so far).
143 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
144     code is shared by all sampler engine implemementations, however only the
145     gig file format currently provides support for storing instrument scripts
146     (as LinuxSampler extension to the original GigaStudio 4 format).
147 iliev 2012
148 persson 2043 * Gigasampler format engine:
149     - implemented the "round robin keyboard" dimension
150     - fixed round robin and random dimensions for cases when number of

153     key
154 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
155     - bugfix: filter keyboard tracking was broken
156     - filter performance fix (an unnecessary copy was made of the
157     filter parameters in each sub fragment)
158     - handle special case when pan parameter in gig file has max or
159     min value
160 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
161     doesn't sound naturally with a drumkit

570     (fixes #208)
571 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
572     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
573     practically irrelevant, however it caused problems with the new LSCP
574     shell's auto completion feature).
575 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
576     after each other (fixes #231).

690 iliev 1727 - added support for handling lost files in the instruments database
691 iliev 1781 - Implemented option for adding instruments in separate directories
692     in the instruments database
693     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
694 persson 1908 - work-around for missing fnmatch function on Windows to make
695     instrument database compilable
696 schoenebeck 1930 - added instrument database support on Windows
697     works with both standalone mode and VST plugin.
698     the instruments DB file is located in
699     %USERPROFILE%\.linuxsampler\instruments.db which allows different
700     databases for each windows user
701     if no DB is present it automatically creates the .linuxsampler subdir
702     and then creates an empty DB
703 persson 1943 - fixed recursive import, which was broken on Windows
704 iliev 1603
705 persson 1644 * Gigasampler format engine:
706     - fixed a memory leak that could happen when a channel was deleted
707     while notes were playing
708 persson 1646 - made it possible to load an instrument even if the audio thread
709     isn't running
710 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
711     enough for piano gigs with pedal noise samples
712 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
713     respective FX send MIDI controller was used
714 schoenebeck 1724 - added support for GM global device volume SysEx message
715 schoenebeck 1762 (can be selected at compile time to either apply globally to the
716     whole sampler [default] or only to the sampler channels that are
717     connected to the respective MIDI input port the SysEx message arrived
718     on)
719 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
720     sometimes wrongly killed in the same buffer, causing no sound to
721     be played
722 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
723     which is usally used to switch a part between chromatic sounds and
724     drumkit sounds (as opposed to their common default setting of MIDI
725     part 10 being a drumkit part and all other ones chromatic parts), in
726     LS however one can switch between the first 16 MIDI instrument maps
727     defined for the sampler
728 persson 1764 - made it possible to create multiple sample channels even if the
729     audio thread isn't running
730 persson 1844 - fixed crash when removing channel with active voices (#116)
731 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
732     un-cache the respective sample if it's really not used by any
733     sampler engine anymore
734     - re-cache samples in case they were changed by an instrument editor,
735     e.g. when a sample was added while playing (#82)
736 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
737     same time stamp as the voice's note-on event and occured both in the
738     same audio fragment cycle (fixes bug #112)
739 persson 1858 - added support for the "fine tune" and "pitch bend range"
740     instrument-level gig parameters
741     - fixed minor artifacts in pitch bend handling
742 schoenebeck 1860 - added support for GS Reset SysEx message
743 persson 1862 - allow gig files to use unlimited downward pitch shifting
744     - added a limit check for upward pitch shifting
745 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
746     note was silent
747 persson 1923 - fixed crash happening when a pitch bend event arrived at the
748     same time a new instrument was loading
749 persson 1644
750 schoenebeck 1687 * LSCP server:
751     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
752     react on MIDI data arriving on certain sampler channels (so far only
753     Note-On and Note-Off events are sent via this LSCP event)
754 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
755     react on MIDI data arriving on certain MIDI input devices (so far only
756     Note-On and Note-Off events are sent via this LSCP event)
757 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
758     SET DB_INSTRUMENT FILE_PATH
759 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
760     frontends to send MIDI messages to specific sampler channel
761     - added two additional fields to GET FILE INSTRUMENT INFO command -
762     KEY_BINDINGS and KEYSWITCH_BINDINGS
763 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
764     was incorrect
765 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
766 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
767     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
768     be triggered respectively
769     - added new LSCP command "SET STREAMS" to globally alter the maximum
770     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
771     which will be triggered respectively
772 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
773     a gigedit file dialog is opened)
774 iliev 1848 - close all connections when LSCPServer is deleted
775 iliev 1882 - hard close of all sockets on exit
776 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
777     driver
778 schoenebeck 1687
779 iliev 1761 * Bug fixes:
780     - fixed a crash which occurs when removing a sampler channel waiting
781     to start instrument loading after another channel
782 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
783     instrument loading in progress (bug #113)
784 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
785     instrument with PERSISTENT load mode
786 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
787     - fixed memory leaks when issuing the following LSCP commands:
788     GET AUDIO_OUTPUT_DRIVER INFO
789     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
790     GET MIDI_INPUT_DRIVER INFO
791     GET MIDI_INPUT_DRIVER_PARAMETER INFO
792     - fixed possible compilation error when sqlite is not present
793 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
794 iliev 1847 - fixed crash when changing the audio output device of a sampler
795     channel with loaded instrument and start playing notes
796 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
797 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
798     PowerPC, which probably could cause crashes on that platform
799 persson 1889 - fixed a memory management error which could cause a crash when a
800     plugin was unloaded
801 persson 1896 - bugfix: two private structs had the same name, which could cause
802     problems if the linker chose the wrong constructor
803 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
804     Windows
805 iliev 1761
806    
807 schoenebeck 1560 Version 0.5.1 (6 December 2007)
808 schoenebeck 1454
809     * packaging changes:
810     - added autoconf checks for pthread library
811     - added autoconf check for pthread bug found on certain NPTL-enabled
812     glibc versions (see Gentoo bug report #194076)
813 senoner 1502 - added autoconf checks for MS Windows
814 schoenebeck 1454
815 persson 1455 * general changes:
816     - bugfix: the thread used by an editor plugin didn't die when the
817     editor closed
818 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
819     out all the space. operator--() did not apply size_mask after
820     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
821     order to avoid problems with the _NonVolatileReader functions.
822     - bugfix: Stream.h: added a missing divide by BytesPerSample in
823     GetWriteSpace(). Since this function is currently only used in
824     the stream's qsort() compare function, it didn't trigger any
825     bugs.
826     - Resampler.h, Synthesizer.h: cubic interpolation now works in
827     24bit mode too. Faster method to read 24bit words on little
828     endian machines (x86): replaced 3 byte reads + shifts with a 1
829     unaligned 32bit read and shift
830     - experimental support for MS Windows (MIDI input via MME, AUDIO
831     output via ASIO)
832     - made handling of SIGINT signal (Ctrl-C) a bit more robust
833 iliev 1541 - support for monitoring the total number of active disk streams
834     (new LSCP commands: GET TOTAL_STREAM_COUNT,
835     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
836 persson 1455
837 senoner 1500 * AUDIO driver:
838 persson 1534 - added Windows ASIO low latency audio driver
839 senoner 1500
840 senoner 1485 * MIDI driver:
841 schoenebeck 1495 - added MME Windows MIDI driver
842 senoner 1485
843 schoenebeck 1471 * LSCP server:
844     - added support for Windows style path / filenames, however with
845     forward slash path separators instead of backslash
846     (i.e. "C:/foo/bar.gig")
847 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
848     apostrophes as well
849 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
850     "LIST FILE INSTRUMENTS <file>" and
851     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
852     about an arbitrary instrument file on the system where the sampler is
853     running on
854 schoenebeck 1471
855 schoenebeck 1424 Version 0.5.0 (15 October 2007)
856 schoenebeck 947
857 schoenebeck 1065 * packaging changes:
858 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
859     API header files anymore
860 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
861     the Doxygen API documentation (explicitly listed in Doxyfile.in)
862 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
863     capable to execute our autoconf environment, thus no need anymore
864     to maintain the compile time configuration file (osx/version.h) for
865     OSX manually (patch by Toshi Nagata)
866 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
867     parameters
868 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
869     C++ API header files, all implementation internal global definitions
870     are now in global_private.h
871     - atomic.h is not exposed to the C++ API anymore
872     - no need to include config.h anymore for using LS's API header files
873     - fixed warnings in API doc generation
874 schoenebeck 1065
875 schoenebeck 947 * general changes:
876     - replaced the old, confusing MIDI program change mechanism by a
877     flexible MIDI instrument mapper which allows to map arbitrary
878 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
879 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
880     loaded on the respective channel when such MIDI program change
881     messages arrive, beside that, each entry allows to define a life-time
882     strategy for the instrument, so the user can define whether the
883     instrument should i.e. be permanently loaded (to be able to switch
884     quickly among sounds) or i.e. loaded just on demand when the
885     respective program change arrives (to safe RAM space), as well as a
886     global volume factor for each entry, so the user can adjust the volume
887     dynamic of his mapped instrument collection without having to modify
888 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
889     MIDI instrument maps and assign each sampler channel individually
890     a certain map, so that i.e. separation of normal instruments and
891     drumkits is possible
892 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
893     MIDI instrument maps, MIDI instruments, FX sends, global volume.
894 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
895     due to a constant size RingBuffer FIFO which is now replaced by a
896     dynamic (unlimited) size std::list FIFO
897 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
898     output channels for being processed by external effect processors
899     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
900     controllers
901 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
902 iliev 1130 - Implemented new, improved notification system
903 schoenebeck 1149 - fixed compilation errors regarding OSX
904     (patch by Toshi Nagata)
905 iliev 1161 - implemented instruments database
906 iliev 1345 - added support for escape sequences to the instruments database
907 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
908     within the sampler's process (by using instrument editor plugins),
909     you'll notice the new "Registered instrument editors:" message on
910 schoenebeck 1407 startup, added a new LSCP command:
911     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
912 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
913     given sampler channel, the plugin path can be overridden at compile
914     time with ./configure --enable-plugin-dir=/some/dir
915 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
916     in the sampler's process to safely edit instruments while playing
917     without a crash (hopefully) by either suspending single regions
918     wherever possible or if unavoidable whole engine(s)
919 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
920     policy and priority on thread level, set a minimum stack size for
921     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
922     threads simply inherited properties of starting thread instead of
923     setting their own policy and priority
924 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
925     main process did not wait for the stack trace process to finish
926     its output
927 persson 1248 - fixed some minor memory leaks
928 schoenebeck 1259 - reenabled assembly features support, at the moment only for
929     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
930 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
931     register, to avoid relocations in the text segment at runtime)
932 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
933 schoenebeck 947
934     * MIDI driver:
935     - dispatch bank select (MSB and LSB) messages
936    
937 schoenebeck 1049 * audio driver:
938     - the ALSA audio output driver parameters now reflect the correct
939     parameter value ranges for the respective selected sound card
940     (patch by Till Wimmer, a bit fixed and extended)
941    
942 persson 951 * Gigasampler format engine:
943     - if a filter is used and EG2 finishes before EG1, let the voice
944     die when EG2 has finished (this fixes a problem with clicks and
945     voice starvation for some gigs)
946 persson 1038 - playback is no longer disabled during instrument loading
947     - all notes playing on a channel that changes its instrument keep
948     playing with the old instrument until they get a note off
949     command
950 persson 1039 - EG fix: a release value of zero could cause noises or crash
951 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
952 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
953     above max sustain level, which means that there is a decay phase
954     even if sustain is 100%
955 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
956     noises or crashes
957 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
958 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
959     supplied to the configure script (fixes #46)
960 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
961     instead of a fix value
962 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
963     127 (solo mode) only kill voices if the respective mode really
964     changed
965 persson 951
966 schoenebeck 1244 * LSCP server:
967     - fixed compile time error for old Bison versions
968     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
969 schoenebeck 1245 - parser now supports extended ASCII character set
970     (up to ASCII code 255, i.e. includes now umlauts and accents)
971     - filename arguments in LSCP commands now allow to use escape
972     sequences, that is directly literal as one of: \', \", \\, \n, \r,
973     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
974     code value like \xf2) (fixes bug #24)
975 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
976     least one of their text-based parameters (i.e. name, description):
977     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
978     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
979     "SET DB_INSTRUMENT_DIRECTORY NAME",
980     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
981     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
982     "FIND DB_INSTRUMENT_DIRECTORIES"
983 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
984     occured, the unexpected character and the actually expected, possible
985     character(s), the latter only if less than 5 possibilities)
986 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
987     settings
988 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
989     of strings were treated as being one string containing commas
990     (fixes #57)
991 schoenebeck 1244
992 iliev 959 * Bug fixes:
993     - fixed crash occurring on certain LSCP scripts (Bug 39)
994 persson 1038 - another thread safety fix for lscp "load engine" and "set
995     channel audio output device"
996 iliev 1283 - fixed a crash which occurs when reassigning the same engine
997     on a sampler channel with connected MIDI device
998 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
999     device connected to a sampler channel to number less then or equal
1000     to the index of the port to which the sampler channel is connected.
1001 iliev 1296 - The previous bindings were not been disconnected when altering
1002     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1003     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1004 iliev 1297 - The active stream/voice count statistic was incorrect.
1005 iliev 1298 - notification events were not been sent for some sampler
1006     channel changes
1007 iliev 1305 - added default min and max values to restrict the number of allowed
1008     audio output channels and MIDI input ports
1009 iliev 1306 - the connection to the PCM interface is now closed when destroying
1010     an audio output device
1011 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1012 iliev 959
1013 schoenebeck 1221 * test cases:
1014     - updated and fixed (haven't been touched in a while)
1015    
1016 schoenebeck 937 Version 0.4.0 (24 November 2006)
1017 persson 696
1018 schoenebeck 697 * packaging changes:
1019 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1020     to post-(un)install steps; added devel package for liblinuxsampler;
1021     to linuxsampler.spec (RPM)
1022 schoenebeck 697 - install necessary development header files for allowing 3rd party
1023     applications to link against liblinuxsampler
1024     - liblinuxsampler's API documentation can be generated with 'make docs'
1025     (Doxygen required)
1026 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1027     implementation (currently either an integer math solution or a
1028     di-harmonic approximation), automatic detection can be overriden
1029     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1030     configure script argument though (mandatory for cross-compilation)
1031 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1032     provided some on his own (as CXXFLAGS)
1033 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1034     messages
1035 schoenebeck 852 - added compile time options to allow disabling the various audio and
1036     MIDI drivers
1037 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1038     (patch by Ebrahim Mayat)
1039 schoenebeck 697
1040 persson 696 * Gigasampler format engine:
1041 schoenebeck 738 - extensive synthesis optimization
1042     (reimplementation of EGs and LFO(s), removed synthesis parameter
1043     prerendering and the synthesis parameter matrix in general, splitting
1044     each audio fragment into subfragments now where each subfragment uses
1045 persson 830 constant pitch and filter coefficients. The volume coefficient is
1046     linearly interpolated inside a subfragment, unless
1047     --disable-interpolate-volume is set.)
1048 persson 696 - fine tuning of the EG modulation parameters
1049 persson 729 - improved filter cutoff calculation by adding support for the
1050     following gig parameters: Cutoff freq (used when no cutoff
1051     controller is defined), Control invert, Minimum cutoff, Velocity
1052 persson 791 curve and Velocity range. The keyboard tracking now scales
1053     cutoff frequency instead of resonance.
1054 persson 877 - added support for gig parameter Resonance.
1055 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1056 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1057     which can be overridden with --enable-global-attenuation
1058 persson 783 - EG fixes: made the length of "attack hold" stage more
1059     accurate. Release stage can now start before attack stage
1060 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1061     time now has a minimal value to prevent clicks.
1062 persson 799 - fixed pitch changes larger than one octave
1063 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1064     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1065     all modes can be altered via standard GM messages, that is CC5 for
1066     altering portamento time, CC65 for enabling / disabling portamento
1067     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1068 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1069     parameter) and crossfade
1070 persson 831 - added support for the "attenuation controller threshold" gig
1071     parameter
1072 persson 832 - added smoothing of volume changes caused by control change
1073     messages
1074 persson 865 - sample loop parameters are now taken from the DimensionRegion
1075     instead of the wave chunk
1076     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1077     not equal to a power of two
1078 persson 877 - reimplementation of the filter algorithm. The new filter is more
1079     accurate and supports all gig filter types, including bandreject
1080     and lowpass turbo.
1081 persson 903 - real support for 24 bit samples - samples are not truncated to
1082     16 bits anymore
1083     - support for aftertouch (channel pressure, not polyphonic
1084     aftertouch)
1085 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1086     amplifying from 0)
1087 persson 696
1088 schoenebeck 711 * LSCP server:
1089     - fixed application exit on broken pipe error (fixes bug #20)
1090 iliev 793 - fixed the notification messages delay due to lack of
1091     network activity (fixes bug #26)
1092 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1093     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1094 schoenebeck 711
1095 schoenebeck 838 * audio driver:
1096     - added aRts audio output driver (by no means RT safe)
1097    
1098 schoenebeck 775 * MIDI driver:
1099     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1100     messages several times instead of once
1101 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1102     for events (i.e. for offline rendering based MIDI drivers)
1103 persson 922 - added checks for bad MIDI data
1104 schoenebeck 775
1105 schoenebeck 900 * linuxsampler application:
1106     - show available sampler engine types on startup
1107    
1108 schoenebeck 705 * general changes:
1109     - support for muting sampler channels and solo mode of the same, two new
1110     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1111     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1112     introduced for this, the behavior is the same like on a mixer console
1113 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1114     --enable-process-muted-channels which can be used to enable the
1115     processing of muted channels.
1116 iliev 777 - support for sostenuto pedal
1117 iliev 779 - support for monitoring the total number of active voices
1118 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1119     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1120 persson 835 - fixed some memory management errors
1121 persson 841 - fixed some concurrency problems that could lead to crashes when
1122     LSCP commands were executed
1123 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1124     sampler channel (fixes bug #36)
1125 schoenebeck 705
1126 schoenebeck 692 Version 0.3.3 (15 July 2005)
1127 schoenebeck 686
1128     * packaging changes:
1129     - fixed compilation with gcc 4.0
1130    
1131 schoenebeck 687 * Gigasampler format engine:
1132     - LFO preprocessing was performed even though the respective LFO was
1133     disabled by the instrument patch (minor efficiency fix)
1134 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1135     for volume ramp downs in the same fragment (needed for current voice
1136     stealing implementation) then simply inform the user with a warning
1137     about possible click sounds and reduce the volume ramp down
1138     appropriately instead of cancelling the audio device connection
1139 schoenebeck 687
1140 schoenebeck 677 Version 0.3.2 (24 June 2005)
1141 schoenebeck 609
1142     * packaging changes:
1143     - updated autotools build files to compile on OS X
1144     (conditional compilation of CoreMIDI and MidiShare drivers)
1145 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1146     './configure --disable-asm' (definitely not recommended)
1147 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1148     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1149     (due to 'dist-bzip2' automake option)
1150 schoenebeck 649
1151     * Gigasampler format engine:
1152     - support for the gig parameters for "release velocity response" curves
1153     - fine tuning of the EGADSR envelope
1154     - volume of release triggered samples now depends on note-on velocity,
1155     note length and gig parameter "release trigger decay" instead of
1156     note-off velocity.
1157 schoenebeck 663 - revised voice stealing
1158     (fixes crash and endless loop caused by voice stealing)
1159 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1160 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1161     instead of when the respective voice is actually launched
1162     (fixes undefined behavior if stolen voices belonged to a key group -
1163     this case was followed by a "killed voice survived" error message)
1164 schoenebeck 669 - fixed minor issue with null/silence samples
1165     (those stole voices even though they don't need a voice at all which
1166     resulted in "voice stealing didn't work out" messages)
1167 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1168     instrument or audio output device change
1169 schoenebeck 654
1170 schoenebeck 620 * LSCP server:
1171 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1172 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1173 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1174 schoenebeck 609
1175 schoenebeck 668 * linuxsampler application:
1176     - added command line parameters --lscp-addr and --lscp-port to override
1177     default IP address and port of LSCP server
1178    
1179 schoenebeck 579 Version 0.3.1 (24 May 2005)
1180    
1181     * initial release
