Mon Apr 25 17:28:23 2016 UTC (4 years, 1 month ago) by schoenebeck
File size: 63884 byte(s)
* Added new C++ API class "ScriptVMFactory".
* Instrument Scripts: extended parser issues to provide not only first
  line and first column, but also last line and last column of issue
  (thus marking the precise span of the issue within the source code).
* Bumped version (2.0.0.svn7).

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 persson 2837
24 schoenebeck 2866 * packaging changes:
25     - removed unnecessary dependency to libuuid
26     (originated by libgig's usage of it)
27 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28     auto detect whether it (sh/c)ould output its messages in color.
29 schoenebeck 2866
30 schoenebeck 2871 * Real-time instrument scripts:
31     - Implemented scheduler for delayed MIDI events and for suspended scripts.
32     - Built-in script function "wait()": implemented support for function's
33     "duration-us" argument, thus scripts using this function are now
34     correctly resumed after the requested amount of microseconds.
35     - Built-in script function "play_note()": implemented support for
36     function's "duration-us" argument, thus notes triggered with this
37     argument are now correctly released after the requested amount of
38     microseconds.
39     - Fix: script events were not cleared when engine channel was reset,
40     potentially causing undefined behavior.
41     - Fixed crash which happened when trying to reference an undeclared
42     variable.
43 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
44     special value -1 for "duration-us" argument, which will cause the
45     triggered note to be released once the original note was released.
46 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
47     - Added new API method ScriptVM::syntaxHighlighting() which provides
48     a convenient syntax highlighting backend for external instrument
49     script editor applications.
50 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
51     - Extended parser issues to provide not only first line and first
52     column, but also last line and last column of issue (thus marking
53     the precise span of the issue within the source code).
54 schoenebeck 2871

65 persson 2203 - another "make dist" fix, for the LV2 plugin
66 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
67 persson 2197 - minor Makefile fix for building lscpparser when build and source

91 persson 2519 - enabled automake 'subdir-objects' option and moved external
92     source references (vst, au, asio) from makefiles to cpp files,
93     in order to get rid of warnings from automake 1.14
94 persson 2382
95 persson 2086 * general changes:
96 iliev 2012 - Refactoring: moved the independent code from
97     the Gigasampler format engine to base classes
98 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
99     respective profiling code is currently broken
100 schoenebeck 2053 - Introduced support for optional environment variable
101     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
102     where the sampler shall look for instrument editor plugins
103     (patch by Luis Garrido, slightly modified).
104 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
105     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
106     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
107     note (in this implementation of the sampler its simply hard routed to
108     the 1st effect send of the sampler channel, no matter what the actual
109     effect type is)
110     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
111     note (in this implementation of the sampler its simply hard routed to
112     the 2nd effect send of the sampler channel, no matter what the actual
113     effect type is)
114 schoenebeck 2124 - implemented support for internal LADSPA effects
115 schoenebeck 2140 - raised limit of program change queue from 100 to 512
116     (as suggested by Alex Stone)
117 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
118 iliev 2296 - experimental support for per voice equalization
119 iliev 2306 - added command line option --exec-after-init
120 schoenebeck 2330 - Introduced new C++ API method:
121     EngineChannel::InstrumentFileName(int index)
122     allowing to retrieve the whole list of files used for the loaded
123     instrument on an engine channel (a.k.a. part). Some GigaStudio
124     instruments for example are splitted over several files like
125     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
126 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
127     - Added new C++ API method Sampler::GetGlobalMaxStreams().
128     - Added new C++ API method Sampler::SetGlobalMaxVoices().
129     - Added new C++ API method Sampler::SetGlobalMaxStreams().
130 schoenebeck 2377 - Various "const" and "restrict" optimizations.
131 persson 2382 - all engines: add pan CC value to instrument pan parameter before
132     applying panning, instead of using two separate pan functions in
133     series (#182)
134 persson 2427 - added a lock guard class for exception safe mutex handling and
135     used it everywhere appropriate
136 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
137     - Exposed scale tuning to C++ API (along to the already existing standard
138     SysEx way).
139 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
140     and broken for ppc64. (Seq_cst loads and stores are actually not
141     used in LS, so the bug wasn't noticable.)
142     - lsatomic.h: added ARMv7 support
143 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
144     added various new C++ methods for this new feature / design change, old
145     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
146     as deprecated but are still there and should provide full behavior
147     backward compatibility).
148     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
149     unsafe and caused compilation error with clang 2.x).
150 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
151 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
152     sampler from the command line by providing LSCP aware features.
153 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
154     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
155     - VirtualMidiDevice: Added support for pitch bend.
156 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
157     polyphonic key pressure events (so far polyphonic pressure was not
158     supported at all, and channel pressure was rerouted as CC128 but not
159     used so far).
160 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
161     code is shared by all sampler engine implemementations, however only the
162     gig file format currently provides support for storing instrument scripts
163     (as LinuxSampler extension to the original GigaStudio 4 format).
164 iliev 2012
165 persson 2043 * Gigasampler format engine:
166     - implemented the "round robin keyboard" dimension
167     - fixed round robin and random dimensions for cases when number of

171 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
172     - bugfix: filter keyboard tracking was broken
173     - filter performance fix (an unnecessary copy was made of the
174     filter parameters in each sub fragment)
175     - handle special case when pan parameter in gig file has max or
176     min value
177 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
178     doesn't sound naturally with a drumkit
179 persson 2408 - fixed EG1 modulation when attack or release is zero
180 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.

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

647     a pointer to the launched InstrumentEditor object
648 schoenebeck 1876 - added optional 3rd party user data parameter for following

696     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
697 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
698 persson 1887 CoreMidi or AU
699 persson 1889 - fixed mingw-w64 compilation error in MME driver
700 persson 1924 - made program change handling in MIDI thread real-time safe by
701     moving the logic to a non-RT thread
702 persson 1951 - fixed minor memory leak in ALSA driver
703 persson 1651
704 schoenebeck 1604 * instruments database:
705 iliev 1603 - avoid time consuming samples scanning when adding instruments
706     to the instruments database
707 iliev 1727 - added support for handling lost files in the instruments database
708 iliev 1781 - Implemented option for adding instruments in separate directories
709     in the instruments database
710     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
711 persson 1908 - work-around for missing fnmatch function on Windows to make
712     instrument database compilable
713 schoenebeck 1930 - added instrument database support on Windows
714     works with both standalone mode and VST plugin.
715     the instruments DB file is located in
716     %USERPROFILE%\.linuxsampler\instruments.db which allows different
717     databases for each windows user
718     if no DB is present it automatically creates the .linuxsampler subdir
719     and then creates an empty DB
720 persson 1943 - fixed recursive import, which was broken on Windows
721 iliev 1603
722 persson 1644 * Gigasampler format engine:
723     - fixed a memory leak that could happen when a channel was deleted
724     while notes were playing
725 persson 1646 - made it possible to load an instrument even if the audio thread
726     isn't running
727 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
728     enough for piano gigs with pedal noise samples
729 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
730     respective FX send MIDI controller was used
731 schoenebeck 1724 - added support for GM global device volume SysEx message
732 schoenebeck 1762 (can be selected at compile time to either apply globally to the
733     whole sampler [default] or only to the sampler channels that are
734     connected to the respective MIDI input port the SysEx message arrived
735     on)
736 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
737     sometimes wrongly killed in the same buffer, causing no sound to
738     be played
739 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
740     which is usally used to switch a part between chromatic sounds and
741     drumkit sounds (as opposed to their common default setting of MIDI
742     part 10 being a drumkit part and all other ones chromatic parts), in
743     LS however one can switch between the first 16 MIDI instrument maps
744     defined for the sampler
745 persson 1764 - made it possible to create multiple sample channels even if the
746     audio thread isn't running
747 persson 1844 - fixed crash when removing channel with active voices (#116)
748 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
749     un-cache the respective sample if it's really not used by any
750     sampler engine anymore
751     - re-cache samples in case they were changed by an instrument editor,
752     e.g. when a sample was added while playing (#82)
753 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
754     same time stamp as the voice's note-on event and occured both in the
755     same audio fragment cycle (fixes bug #112)
756 persson 1858 - added support for the "fine tune" and "pitch bend range"
757     instrument-level gig parameters
758     - fixed minor artifacts in pitch bend handling
759 schoenebeck 1860 - added support for GS Reset SysEx message
760 persson 1862 - allow gig files to use unlimited downward pitch shifting
761     - added a limit check for upward pitch shifting
762 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
763     note was silent
764 persson 1923 - fixed crash happening when a pitch bend event arrived at the
765     same time a new instrument was loading
766 persson 1644
767 schoenebeck 1687 * LSCP server:
768     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
769     react on MIDI data arriving on certain sampler channels (so far only
770     Note-On and Note-Off events are sent via this LSCP event)
771 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
772     react on MIDI data arriving on certain MIDI input devices (so far only
773     Note-On and Note-Off events are sent via this LSCP event)
774 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
775     SET DB_INSTRUMENT FILE_PATH
776 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
777     frontends to send MIDI messages to specific sampler channel
778     - added two additional fields to GET FILE INSTRUMENT INFO command -
779     KEY_BINDINGS and KEYSWITCH_BINDINGS
780 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
781     was incorrect
782 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
783 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
784     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
785     be triggered respectively
786     - added new LSCP command "SET STREAMS" to globally alter the maximum
787     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
788     which will be triggered respectively
789 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
790     a gigedit file dialog is opened)
791 iliev 1848 - close all connections when LSCPServer is deleted
792 iliev 1882 - hard close of all sockets on exit
793 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
794     driver
795 schoenebeck 1687
796 iliev 1761 * Bug fixes:
797     - fixed a crash which occurs when removing a sampler channel waiting
798     to start instrument loading after another channel
799 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
800     instrument loading in progress (bug #113)
801 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
802     instrument with PERSISTENT load mode
803 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
804     - fixed memory leaks when issuing the following LSCP commands:
805     GET AUDIO_OUTPUT_DRIVER INFO
806     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
807     GET MIDI_INPUT_DRIVER INFO
808     GET MIDI_INPUT_DRIVER_PARAMETER INFO
809     - fixed possible compilation error when sqlite is not present
810 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
811 iliev 1847 - fixed crash when changing the audio output device of a sampler
812     channel with loaded instrument and start playing notes
813 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
814 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
815     PowerPC, which probably could cause crashes on that platform
816 persson 1889 - fixed a memory management error which could cause a crash when a
817     plugin was unloaded
818 persson 1896 - bugfix: two private structs had the same name, which could cause
819     problems if the linker chose the wrong constructor
820 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
821     Windows
822 iliev 1761
823    
824 schoenebeck 1560 Version 0.5.1 (6 December 2007)
825 schoenebeck 1454
826     * packaging changes:
827     - added autoconf checks for pthread library
828     - added autoconf check for pthread bug found on certain NPTL-enabled
829     glibc versions (see Gentoo bug report #194076)
830 senoner 1502 - added autoconf checks for MS Windows
831 schoenebeck 1454
832 persson 1455 * general changes:
833     - bugfix: the thread used by an editor plugin didn't die when the
834     editor closed
835 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
836     out all the space. operator--() did not apply size_mask after
837     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
838     order to avoid problems with the _NonVolatileReader functions.
839     - bugfix: Stream.h: added a missing divide by BytesPerSample in
840     GetWriteSpace(). Since this function is currently only used in
841     the stream's qsort() compare function, it didn't trigger any
842     bugs.
843     - Resampler.h, Synthesizer.h: cubic interpolation now works in
844     24bit mode too. Faster method to read 24bit words on little
845     endian machines (x86): replaced 3 byte reads + shifts with a 1
846     unaligned 32bit read and shift
847     - experimental support for MS Windows (MIDI input via MME, AUDIO
848     output via ASIO)
849     - made handling of SIGINT signal (Ctrl-C) a bit more robust
850 iliev 1541 - support for monitoring the total number of active disk streams
851     (new LSCP commands: GET TOTAL_STREAM_COUNT,
852     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
853 persson 1455
854 senoner 1500 * AUDIO driver:
855 persson 1534 - added Windows ASIO low latency audio driver
856 senoner 1500
857 senoner 1485 * MIDI driver:
858 schoenebeck 1495 - added MME Windows MIDI driver
859 senoner 1485
860 schoenebeck 1471 * LSCP server:
861     - added support for Windows style path / filenames, however with
862     forward slash path separators instead of backslash
863     (i.e. "C:/foo/bar.gig")
864 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
865     apostrophes as well
866 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
867     "LIST FILE INSTRUMENTS <file>" and
868     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
869     about an arbitrary instrument file on the system where the sampler is
870     running on
871 schoenebeck 1471
872 schoenebeck 1424 Version 0.5.0 (15 October 2007)
873 schoenebeck 947
874 schoenebeck 1065 * packaging changes:
875 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
876     API header files anymore
877 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
878     the Doxygen API documentation (explicitly listed in Doxyfile.in)
879 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
880     capable to execute our autoconf environment, thus no need anymore
881     to maintain the compile time configuration file (osx/version.h) for
882     OSX manually (patch by Toshi Nagata)
883 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
884     parameters
885 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
886     C++ API header files, all implementation internal global definitions
887     are now in global_private.h
888     - atomic.h is not exposed to the C++ API anymore
889     - no need to include config.h anymore for using LS's API header files
890     - fixed warnings in API doc generation
891 schoenebeck 1065
892 schoenebeck 947 * general changes:
893     - replaced the old, confusing MIDI program change mechanism by a
894     flexible MIDI instrument mapper which allows to map arbitrary
895 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
896 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
897     loaded on the respective channel when such MIDI program change
898     messages arrive, beside that, each entry allows to define a life-time
899     strategy for the instrument, so the user can define whether the
900     instrument should i.e. be permanently loaded (to be able to switch
901     quickly among sounds) or i.e. loaded just on demand when the
902     respective program change arrives (to safe RAM space), as well as a
903     global volume factor for each entry, so the user can adjust the volume
904     dynamic of his mapped instrument collection without having to modify
905 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
906     MIDI instrument maps and assign each sampler channel individually
907     a certain map, so that i.e. separation of normal instruments and
908     drumkits is possible
909 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
910     MIDI instrument maps, MIDI instruments, FX sends, global volume.
911 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
912     due to a constant size RingBuffer FIFO which is now replaced by a
913     dynamic (unlimited) size std::list FIFO
914 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
915     output channels for being processed by external effect processors
916     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
917     controllers
918 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
919 iliev 1130 - Implemented new, improved notification system
920 schoenebeck 1149 - fixed compilation errors regarding OSX
921     (patch by Toshi Nagata)
922 iliev 1161 - implemented instruments database
923 iliev 1345 - added support for escape sequences to the instruments database
924 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
925     within the sampler's process (by using instrument editor plugins),
926     you'll notice the new "Registered instrument editors:" message on
927 schoenebeck 1407 startup, added a new LSCP command:
928     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
929 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
930     given sampler channel, the plugin path can be overridden at compile
931     time with ./configure --enable-plugin-dir=/some/dir
932 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
933     in the sampler's process to safely edit instruments while playing
934     without a crash (hopefully) by either suspending single regions
935     wherever possible or if unavoidable whole engine(s)
936 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
937     policy and priority on thread level, set a minimum stack size for
938     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
939     threads simply inherited properties of starting thread instead of
940     setting their own policy and priority
941 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
942     main process did not wait for the stack trace process to finish
943     its output
944 persson 1248 - fixed some minor memory leaks
945 schoenebeck 1259 - reenabled assembly features support, at the moment only for
946     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
947 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
948     register, to avoid relocations in the text segment at runtime)
949 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
950 schoenebeck 947
951     * MIDI driver:
952     - dispatch bank select (MSB and LSB) messages
953    
954 schoenebeck 1049 * audio driver:
955     - the ALSA audio output driver parameters now reflect the correct
956     parameter value ranges for the respective selected sound card
957     (patch by Till Wimmer, a bit fixed and extended)
958    
959 persson 951 * Gigasampler format engine:
960     - if a filter is used and EG2 finishes before EG1, let the voice
961     die when EG2 has finished (this fixes a problem with clicks and
962     voice starvation for some gigs)
963 persson 1038 - playback is no longer disabled during instrument loading
964     - all notes playing on a channel that changes its instrument keep
965     playing with the old instrument until they get a note off
966     command
967 persson 1039 - EG fix: a release value of zero could cause noises or crash
968 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
969 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
970     above max sustain level, which means that there is a decay phase
971     even if sustain is 100%
972 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
973     noises or crashes
974 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
975 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
976     supplied to the configure script (fixes #46)
977 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
978     instead of a fix value
979 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
980     127 (solo mode) only kill voices if the respective mode really
981     changed
982 persson 951
983 schoenebeck 1244 * LSCP server:
984     - fixed compile time error for old Bison versions
985     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
986 schoenebeck 1245 - parser now supports extended ASCII character set
987     (up to ASCII code 255, i.e. includes now umlauts and accents)
988     - filename arguments in LSCP commands now allow to use escape
989     sequences, that is directly literal as one of: \', \", \\, \n, \r,
990     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
991     code value like \xf2) (fixes bug #24)
992 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
993     least one of their text-based parameters (i.e. name, description):
994     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
995     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
996     "SET DB_INSTRUMENT_DIRECTORY NAME",
997     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
998     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
999     "FIND DB_INSTRUMENT_DIRECTORIES"
1000 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1001     occured, the unexpected character and the actually expected, possible
1002     character(s), the latter only if less than 5 possibilities)
1003 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1004     settings
1005 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1006     of strings were treated as being one string containing commas
1007     (fixes #57)
1008 schoenebeck 1244
1009 iliev 959 * Bug fixes:
1010     - fixed crash occurring on certain LSCP scripts (Bug 39)
1011 persson 1038 - another thread safety fix for lscp "load engine" and "set
1012     channel audio output device"
1013 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1014     on a sampler channel with connected MIDI device
1015 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1016     device connected to a sampler channel to number less then or equal
1017     to the index of the port to which the sampler channel is connected.
1018 iliev 1296 - The previous bindings were not been disconnected when altering
1019     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1020     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1021 iliev 1297 - The active stream/voice count statistic was incorrect.
1022 iliev 1298 - notification events were not been sent for some sampler
1023     channel changes
1024 iliev 1305 - added default min and max values to restrict the number of allowed
1025     audio output channels and MIDI input ports
1026 iliev 1306 - the connection to the PCM interface is now closed when destroying
1027     an audio output device
1028 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1029 iliev 959
1030 schoenebeck 1221 * test cases:
1031     - updated and fixed (haven't been touched in a while)
1032    
1033 schoenebeck 937 Version 0.4.0 (24 November 2006)
1034 persson 696
1035 schoenebeck 697 * packaging changes:
1036 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1037     to post-(un)install steps; added devel package for liblinuxsampler;
1038     to linuxsampler.spec (RPM)
1039 schoenebeck 697 - install necessary development header files for allowing 3rd party
1040     applications to link against liblinuxsampler
1041     - liblinuxsampler's API documentation can be generated with 'make docs'
1042     (Doxygen required)
1043 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1044     implementation (currently either an integer math solution or a
1045     di-harmonic approximation), automatic detection can be overriden
1046     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1047     configure script argument though (mandatory for cross-compilation)
1048 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1049     provided some on his own (as CXXFLAGS)
1050 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1051     messages
1052 schoenebeck 852 - added compile time options to allow disabling the various audio and
1053     MIDI drivers
1054 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1055     (patch by Ebrahim Mayat)
1056 schoenebeck 697
1057 persson 696 * Gigasampler format engine:
1058 schoenebeck 738 - extensive synthesis optimization
1059     (reimplementation of EGs and LFO(s), removed synthesis parameter
1060     prerendering and the synthesis parameter matrix in general, splitting
1061     each audio fragment into subfragments now where each subfragment uses
1062 persson 830 constant pitch and filter coefficients. The volume coefficient is
1063     linearly interpolated inside a subfragment, unless
1064     --disable-interpolate-volume is set.)
1065 persson 696 - fine tuning of the EG modulation parameters
1066 persson 729 - improved filter cutoff calculation by adding support for the
1067     following gig parameters: Cutoff freq (used when no cutoff
1068     controller is defined), Control invert, Minimum cutoff, Velocity
1069 persson 791 curve and Velocity range. The keyboard tracking now scales
1070     cutoff frequency instead of resonance.
1071 persson 877 - added support for gig parameter Resonance.
1072 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1073 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1074     which can be overridden with --enable-global-attenuation
1075 persson 783 - EG fixes: made the length of "attack hold" stage more
1076     accurate. Release stage can now start before attack stage
1077 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1078     time now has a minimal value to prevent clicks.
1079 persson 799 - fixed pitch changes larger than one octave
1080 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1081     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1082     all modes can be altered via standard GM messages, that is CC5 for
1083     altering portamento time, CC65 for enabling / disabling portamento
1084     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1085 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1086     parameter) and crossfade
1087 persson 831 - added support for the "attenuation controller threshold" gig
1088     parameter
1089 persson 832 - added smoothing of volume changes caused by control change
1090     messages
1091 persson 865 - sample loop parameters are now taken from the DimensionRegion
1092     instead of the wave chunk
1093     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1094     not equal to a power of two
1095 persson 877 - reimplementation of the filter algorithm. The new filter is more
1096     accurate and supports all gig filter types, including bandreject
1097     and lowpass turbo.
1098 persson 903 - real support for 24 bit samples - samples are not truncated to
1099     16 bits anymore
1100     - support for aftertouch (channel pressure, not polyphonic
1101     aftertouch)
1102 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1103     amplifying from 0)
1104 persson 696
1105 schoenebeck 711 * LSCP server:
1106     - fixed application exit on broken pipe error (fixes bug #20)
1107 iliev 793 - fixed the notification messages delay due to lack of
1108     network activity (fixes bug #26)
1109 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1110     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1111 schoenebeck 711
1112 schoenebeck 838 * audio driver:
1113     - added aRts audio output driver (by no means RT safe)
1114    
1115 schoenebeck 775 * MIDI driver:
1116     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1117     messages several times instead of once
1118 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1119     for events (i.e. for offline rendering based MIDI drivers)
1120 persson 922 - added checks for bad MIDI data
1121 schoenebeck 775
1122 schoenebeck 900 * linuxsampler application:
1123     - show available sampler engine types on startup
1124    
1125 schoenebeck 705 * general changes:
1126     - support for muting sampler channels and solo mode of the same, two new
1127     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1128     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1129     introduced for this, the behavior is the same like on a mixer console
1130 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1131     --enable-process-muted-channels which can be used to enable the
1132     processing of muted channels.
1133 iliev 777 - support for sostenuto pedal
1134 iliev 779 - support for monitoring the total number of active voices
1135 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1136     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1137 persson 835 - fixed some memory management errors
1138 persson 841 - fixed some concurrency problems that could lead to crashes when
1139     LSCP commands were executed
1140 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1141     sampler channel (fixes bug #36)
1142 schoenebeck 705
1143 schoenebeck 692 Version 0.3.3 (15 July 2005)
1144 schoenebeck 686
1145     * packaging changes:
1146     - fixed compilation with gcc 4.0
1147    
1148 schoenebeck 687 * Gigasampler format engine:
1149     - LFO preprocessing was performed even though the respective LFO was
1150     disabled by the instrument patch (minor efficiency fix)
1151 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1152     for volume ramp downs in the same fragment (needed for current voice
1153     stealing implementation) then simply inform the user with a warning
1154     about possible click sounds and reduce the volume ramp down
1155     appropriately instead of cancelling the audio device connection
1156 schoenebeck 687
1157 schoenebeck 677 Version 0.3.2 (24 June 2005)
1158 schoenebeck 609
1159     * packaging changes:
1160     - updated autotools build files to compile on OS X
1161     (conditional compilation of CoreMIDI and MidiShare drivers)
1162 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1163     './configure --disable-asm' (definitely not recommended)
1164 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1165     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1166     (due to 'dist-bzip2' automake option)
1167 schoenebeck 649
1168     * Gigasampler format engine:
1169     - support for the gig parameters for "release velocity response" curves
1170     - fine tuning of the EGADSR envelope
1171     - volume of release triggered samples now depends on note-on velocity,
1172     note length and gig parameter "release trigger decay" instead of
1173     note-off velocity.
1174 schoenebeck 663 - revised voice stealing
1175     (fixes crash and endless loop caused by voice stealing)
1176 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1177 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1178     instead of when the respective voice is actually launched
1179     (fixes undefined behavior if stolen voices belonged to a key group -
1180     this case was followed by a "killed voice survived" error message)
1181 schoenebeck 669 - fixed minor issue with null/silence samples
1182     (those stole voices even though they don't need a voice at all which
1183     resulted in "voice stealing didn't work out" messages)
1184 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1185     instrument or audio output device change
1186 schoenebeck 654
1187 schoenebeck 620 * LSCP server:
1188 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1189 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1190 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1191 schoenebeck 609
1192 schoenebeck 668 * linuxsampler application:
1193     - added command line parameters --lscp-addr and --lscp-port to override
1194     default IP address and port of LSCP server
1195    
1196 schoenebeck 579 Version 0.3.1 (24 May 2005)
1197    
1198     * initial release
