File size: 65839 byte(s)
* NKSP: Implemented built-in script function "inc()".
* NKSP: Implemented built-in script function "dec()".

* NKSP language fix: string concatenation operator was right
  associative instead of left (to right).
* Bumped version (2.0.0.svn15).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5    
6 persson 2837 * general changes:
7     - fixed printf type errors (mostly in debug messages)
8 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
9 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10     allowing to sort data efficiently in real-time safe manner.
11     - RTList class: added methods for moving/inserting elements to arbitrary
12     position within a list.
13     - RTList class: added method fromPtr() for creating an Iterator object from
14     a raw element pointer.
15     - Attempt to partly fix resetting engine channels vs. resetting engine, an
16     overall cleanup of the Reset*(), ConnectAudioDevice(),
17     DisconnectAudioDevice() API methods would still be desirable though,
18     because the current situation is still inconsistent and error prone.
19 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
20     being directly assigned to a keyboard key. This allows more fine graded
21     processing of voices, which is i.e. required for certain instrument
22     script features.
23 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
24     (CC #64) events.
25     - Fix: Release trigger voices can now also distinguish correctly between
26     note-off and sustain pedal up events.
27 persson 2837
28 schoenebeck 2866 * packaging changes:
29     - removed unnecessary dependency to libuuid
30     (originated by libgig's usage of it)
31 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32     auto detect whether it (sh/c)ould output its messages in color.
33 schoenebeck 2866
34 schoenebeck 2871 * Real-time instrument scripts:
35     - Implemented scheduler for delayed MIDI events and for suspended scripts.
36     - Built-in script function "wait()": implemented support for function's
37     "duration-us" argument, thus scripts using this function are now
38     correctly resumed after the requested amount of microseconds.
39     - Built-in script function "play_note()": implemented support for
40     function's "duration-us" argument, thus notes triggered with this
41     argument are now correctly released after the requested amount of
42     microseconds.
43     - Fix: script events were not cleared when engine channel was reset,
44     potentially causing undefined behavior.
45     - Fixed crash which happened when trying to reference an undeclared
46     variable.
47 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
48     special value -1 for "duration-us" argument, which will cause the
49     triggered note to be released once the original note was released.
50 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
51     - Added new API method ScriptVM::syntaxHighlighting() which provides
52     a convenient syntax highlighting backend for external instrument
53     script editor applications.
54 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
55     - Extended parser issues to provide not only first line and first
56     column, but also last line and last column of issue (thus marking
57     the precise span of the issue within the source code).
58 schoenebeck 2902 - Reload script automatically after being modified by an instrument
59     editor.
60 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
61     like "on note end on".
62 schoenebeck 2931 - Implemented built-in script function "change_vol()".
63     - Implemented built-in script function "change_tune()".
64     - Implemented built-in script function "change_pan()".
65 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
66     - Implemented built-in script function "change_reso()".
67     - Implemented built-in script function "event_status()".
68     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70     "event_status()" function.
71     - NKSP language: Added support for bitwise operators ".or.", ".and."
72     and ".not.".
73     - NKSP language scanner: Fixed IDs matching to require at least one
74     character (i.e. when matching function names or variable names).
75     - NKSP language scanner: disabled unusued rules.
76 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
77     be distinguished engine internally from "real" MIDI note on/off
78     events in order to avoid misbehaviors like hanging notes.
79 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
80     - Implemented built-in script variable "$NKSP_REAL_TIMER".
81     - Implemented built-in script variable "$NKSP_PERF_TIMER".
82     - Implemented built-in script variable "$ENGINE_UPTIME".
83 schoenebeck 2945 - Implemented built-in script function "inc()".
84     - Implemented built-in script function "dec()".
85     - NKSP language fix: division expressions were evaluated too often.
86     - NKSP language fix: string concatenation operator was right
87     associative instead of left (to right).

127     in order to get rid of warnings from automake 1.14
128 persson 2382
129 persson 2086 * general changes:
130 iliev 2012 - Refactoring: moved the independent code from
131     the Gigasampler format engine to base classes
132 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
133     respective profiling code is currently broken
134 schoenebeck 2053 - Introduced support for optional environment variable
135     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
136     where the sampler shall look for instrument editor plugins
137     (patch by Luis Garrido, slightly modified).
138 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
139     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
140     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
141     note (in this implementation of the sampler its simply hard routed to
142     the 1st effect send of the sampler channel, no matter what the actual
143     effect type is)
144     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
145     note (in this implementation of the sampler its simply hard routed to
146     the 2nd effect send of the sampler channel, no matter what the actual
147     effect type is)
148 schoenebeck 2124 - implemented support for internal LADSPA effects
149 schoenebeck 2140 - raised limit of program change queue from 100 to 512
150     (as suggested by Alex Stone)

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

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

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

664 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
665 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

680 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
681     a pointer to the launched InstrumentEditor object
682 schoenebeck 1876 - added optional 3rd party user data parameter for following
683     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

693 schoenebeck 1601
694 schoenebeck 1599 * audio driver:
695     - removed the nonsense audio channel constraint (which was hard coded to
696     max. 100 audio channels) for most audio drivers
697 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
698     opposed to the LSCP specs
699 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
700     reflected the wrong value
701 persson 1644 - fixed a memory management bug in ASIO driver
702 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
703 persson 1777 - JACK: use jack_client_open instead of the deprecated
704 persson 1748 jack_client_new
705 iliev 1829 - added (experimental) CoreAudio driver
706 persson 1888 - applied old fixes to the ASIO driver that were included in the
707     previous binary release but accidentally never committed to CVS
708     (fixes #117)
709 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
710     win64)
711 persson 1895 - VST: added support for sample rate and buffer size changes
712     - VST: close editor (Fantasia) when the VST is removed
713 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
714     - VST: export main function as "main" on Linux too (fix for
715     energyXT)

717     stereo
718 persson 1922 - added channel routing, fxsends and midi maps to the settings
719     stored in the plugin state
720 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
721     AudioChannel::CopyTo() methods using GCC vector exensions
722     (if available)
723 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
724     exception when getting parameters from a disconnected device
725 schoenebeck 1599
726 persson 1651 * MIDI driver:
727     - added JACK MIDI driver
728 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
729     want to (mis)use it for some purpose ("fixed" in all current MIDI
730     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
731 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
732 persson 1887 CoreMidi or AU
733 persson 1889 - fixed mingw-w64 compilation error in MME driver
734 persson 1924 - made program change handling in MIDI thread real-time safe by
735     moving the logic to a non-RT thread
736 persson 1951 - fixed minor memory leak in ALSA driver
737 persson 1651
738 schoenebeck 1604 * instruments database:
739 iliev 1603 - avoid time consuming samples scanning when adding instruments
740     to the instruments database
741 iliev 1727 - added support for handling lost files in the instruments database
742 iliev 1781 - Implemented option for adding instruments in separate directories
743     in the instruments database
744     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
745 persson 1908 - work-around for missing fnmatch function on Windows to make
746     instrument database compilable
747 schoenebeck 1930 - added instrument database support on Windows
748     works with both standalone mode and VST plugin.
749     the instruments DB file is located in
750     %USERPROFILE%\.linuxsampler\instruments.db which allows different
751     databases for each windows user
752     if no DB is present it automatically creates the .linuxsampler subdir
753     and then creates an empty DB
754 persson 1943 - fixed recursive import, which was broken on Windows
755 iliev 1603
756 persson 1644 * Gigasampler format engine:
757     - fixed a memory leak that could happen when a channel was deleted
758     while notes were playing
759 persson 1646 - made it possible to load an instrument even if the audio thread
760     isn't running
761 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
762     enough for piano gigs with pedal noise samples
763 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
764     respective FX send MIDI controller was used
765 schoenebeck 1724 - added support for GM global device volume SysEx message
766 schoenebeck 1762 (can be selected at compile time to either apply globally to the
767     whole sampler [default] or only to the sampler channels that are
768     connected to the respective MIDI input port the SysEx message arrived
769     on)
770 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
771     sometimes wrongly killed in the same buffer, causing no sound to
772     be played
773 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
774     which is usally used to switch a part between chromatic sounds and
775     drumkit sounds (as opposed to their common default setting of MIDI
776     part 10 being a drumkit part and all other ones chromatic parts), in
777     LS however one can switch between the first 16 MIDI instrument maps
778     defined for the sampler
779 persson 1764 - made it possible to create multiple sample channels even if the
780     audio thread isn't running
781 persson 1844 - fixed crash when removing channel with active voices (#116)
782 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
783     un-cache the respective sample if it's really not used by any
784     sampler engine anymore
785     - re-cache samples in case they were changed by an instrument editor,
786     e.g. when a sample was added while playing (#82)
787 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
788     same time stamp as the voice's note-on event and occured both in the
789     same audio fragment cycle (fixes bug #112)
790 persson 1858 - added support for the "fine tune" and "pitch bend range"
791     instrument-level gig parameters
792     - fixed minor artifacts in pitch bend handling
793 schoenebeck 1860 - added support for GS Reset SysEx message
794 persson 1862 - allow gig files to use unlimited downward pitch shifting
795     - added a limit check for upward pitch shifting
796 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
797     note was silent
798 persson 1923 - fixed crash happening when a pitch bend event arrived at the
799     same time a new instrument was loading
800 persson 1644
801 schoenebeck 1687 * LSCP server:
802     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
803     react on MIDI data arriving on certain sampler channels (so far only
804     Note-On and Note-Off events are sent via this LSCP event)
805 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
806     react on MIDI data arriving on certain MIDI input devices (so far only
807     Note-On and Note-Off events are sent via this LSCP event)
808 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
809     SET DB_INSTRUMENT FILE_PATH
810 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
811     frontends to send MIDI messages to specific sampler channel
812     - added two additional fields to GET FILE INSTRUMENT INFO command -
813     KEY_BINDINGS and KEYSWITCH_BINDINGS
814 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
815     was incorrect
816 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
817 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
818     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
819     be triggered respectively
820     - added new LSCP command "SET STREAMS" to globally alter the maximum
821     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
822     which will be triggered respectively
823 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
824     a gigedit file dialog is opened)
825 iliev 1848 - close all connections when LSCPServer is deleted
826 iliev 1882 - hard close of all sockets on exit
827 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
828     driver
829 schoenebeck 1687
830 iliev 1761 * Bug fixes:
831     - fixed a crash which occurs when removing a sampler channel waiting
832     to start instrument loading after another channel
833 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
834     instrument loading in progress (bug #113)
835 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
836     instrument with PERSISTENT load mode
837 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
838     - fixed memory leaks when issuing the following LSCP commands:
839     GET AUDIO_OUTPUT_DRIVER INFO
840     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
841     GET MIDI_INPUT_DRIVER INFO
842     GET MIDI_INPUT_DRIVER_PARAMETER INFO
843     - fixed possible compilation error when sqlite is not present
844 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
845 iliev 1847 - fixed crash when changing the audio output device of a sampler
846     channel with loaded instrument and start playing notes
847 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
848 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
849     PowerPC, which probably could cause crashes on that platform
850 persson 1889 - fixed a memory management error which could cause a crash when a
851     plugin was unloaded
852 persson 1896 - bugfix: two private structs had the same name, which could cause
853     problems if the linker chose the wrong constructor
854 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
855     Windows
856 iliev 1761
857    
858 schoenebeck 1560 Version 0.5.1 (6 December 2007)
859 schoenebeck 1454
860     * packaging changes:
861     - added autoconf checks for pthread library
862     - added autoconf check for pthread bug found on certain NPTL-enabled
863     glibc versions (see Gentoo bug report #194076)
864 senoner 1502 - added autoconf checks for MS Windows
865 schoenebeck 1454
866 persson 1455 * general changes:
867     - bugfix: the thread used by an editor plugin didn't die when the
868     editor closed
869 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
870     out all the space. operator--() did not apply size_mask after
871     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
872     order to avoid problems with the _NonVolatileReader functions.
873     - bugfix: Stream.h: added a missing divide by BytesPerSample in
874     GetWriteSpace(). Since this function is currently only used in
875     the stream's qsort() compare function, it didn't trigger any
876     bugs.
877     - Resampler.h, Synthesizer.h: cubic interpolation now works in
878     24bit mode too. Faster method to read 24bit words on little
879     endian machines (x86): replaced 3 byte reads + shifts with a 1
880     unaligned 32bit read and shift
881     - experimental support for MS Windows (MIDI input via MME, AUDIO
882     output via ASIO)
883     - made handling of SIGINT signal (Ctrl-C) a bit more robust
884 iliev 1541 - support for monitoring the total number of active disk streams
885     (new LSCP commands: GET TOTAL_STREAM_COUNT,
886     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
887 persson 1455
888 senoner 1500 * AUDIO driver:
889 persson 1534 - added Windows ASIO low latency audio driver
890 senoner 1500
891 senoner 1485 * MIDI driver:
892 schoenebeck 1495 - added MME Windows MIDI driver
893 senoner 1485
894 schoenebeck 1471 * LSCP server:
895     - added support for Windows style path / filenames, however with
896     forward slash path separators instead of backslash
897     (i.e. "C:/foo/bar.gig")
898 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
899     apostrophes as well
900 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
901     "LIST FILE INSTRUMENTS <file>" and
902     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
903     about an arbitrary instrument file on the system where the sampler is
904     running on
905 schoenebeck 1471
906 schoenebeck 1424 Version 0.5.0 (15 October 2007)
907 schoenebeck 947
908 schoenebeck 1065 * packaging changes:
909 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
910     API header files anymore
911 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
912     the Doxygen API documentation (explicitly listed in Doxyfile.in)
913 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
914     capable to execute our autoconf environment, thus no need anymore
915     to maintain the compile time configuration file (osx/version.h) for
916     OSX manually (patch by Toshi Nagata)
917 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
918     parameters
919 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
920     C++ API header files, all implementation internal global definitions
921     are now in global_private.h
922     - atomic.h is not exposed to the C++ API anymore
923     - no need to include config.h anymore for using LS's API header files
924     - fixed warnings in API doc generation
925 schoenebeck 1065
926 schoenebeck 947 * general changes:
927     - replaced the old, confusing MIDI program change mechanism by a
928     flexible MIDI instrument mapper which allows to map arbitrary
929 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
930 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
931     loaded on the respective channel when such MIDI program change
932     messages arrive, beside that, each entry allows to define a life-time
933     strategy for the instrument, so the user can define whether the
934     instrument should i.e. be permanently loaded (to be able to switch
935     quickly among sounds) or i.e. loaded just on demand when the
936     respective program change arrives (to safe RAM space), as well as a
937     global volume factor for each entry, so the user can adjust the volume
938     dynamic of his mapped instrument collection without having to modify
939 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
940     MIDI instrument maps and assign each sampler channel individually
941     a certain map, so that i.e. separation of normal instruments and
942     drumkits is possible
943 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
944     MIDI instrument maps, MIDI instruments, FX sends, global volume.
945 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
946     due to a constant size RingBuffer FIFO which is now replaced by a
947     dynamic (unlimited) size std::list FIFO
948 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
949     output channels for being processed by external effect processors
950     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
951     controllers
952 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
953 iliev 1130 - Implemented new, improved notification system
954 schoenebeck 1149 - fixed compilation errors regarding OSX
955     (patch by Toshi Nagata)
956 iliev 1161 - implemented instruments database
957 iliev 1345 - added support for escape sequences to the instruments database
958 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
959     within the sampler's process (by using instrument editor plugins),
960     you'll notice the new "Registered instrument editors:" message on
961 schoenebeck 1407 startup, added a new LSCP command:
962     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
963 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
964     given sampler channel, the plugin path can be overridden at compile
965     time with ./configure --enable-plugin-dir=/some/dir
966 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
967     in the sampler's process to safely edit instruments while playing
968     without a crash (hopefully) by either suspending single regions
969     wherever possible or if unavoidable whole engine(s)
970 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
971     policy and priority on thread level, set a minimum stack size for
972     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
973     threads simply inherited properties of starting thread instead of
974     setting their own policy and priority
975 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
976     main process did not wait for the stack trace process to finish
977     its output
978 persson 1248 - fixed some minor memory leaks
979 schoenebeck 1259 - reenabled assembly features support, at the moment only for
980     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
981 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
982     register, to avoid relocations in the text segment at runtime)
983 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
984 schoenebeck 947
985     * MIDI driver:
986     - dispatch bank select (MSB and LSB) messages
987    
988 schoenebeck 1049 * audio driver:
989     - the ALSA audio output driver parameters now reflect the correct
990     parameter value ranges for the respective selected sound card
991     (patch by Till Wimmer, a bit fixed and extended)
992    
993 persson 951 * Gigasampler format engine:
994     - if a filter is used and EG2 finishes before EG1, let the voice
995     die when EG2 has finished (this fixes a problem with clicks and
996     voice starvation for some gigs)
997 persson 1038 - playback is no longer disabled during instrument loading
998     - all notes playing on a channel that changes its instrument keep
999     playing with the old instrument until they get a note off
1000     command
1001 persson 1039 - EG fix: a release value of zero could cause noises or crash
1002 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1003 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1004     above max sustain level, which means that there is a decay phase
1005     even if sustain is 100%
1006 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1007     noises or crashes
1008 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1009 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1010     supplied to the configure script (fixes #46)
1011 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1012     instead of a fix value
1013 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1014     127 (solo mode) only kill voices if the respective mode really
1015     changed
1016 persson 951
1017 schoenebeck 1244 * LSCP server:
1018     - fixed compile time error for old Bison versions
1019     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1020 schoenebeck 1245 - parser now supports extended ASCII character set
1021     (up to ASCII code 255, i.e. includes now umlauts and accents)
1022     - filename arguments in LSCP commands now allow to use escape
1023     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1024     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1025     code value like \xf2) (fixes bug #24)
1026 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1027     least one of their text-based parameters (i.e. name, description):
1028     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1029     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1030     "SET DB_INSTRUMENT_DIRECTORY NAME",
1031     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1032     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1033     "FIND DB_INSTRUMENT_DIRECTORIES"
1034 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1035     occured, the unexpected character and the actually expected, possible
1036     character(s), the latter only if less than 5 possibilities)
1037 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1038     settings
1039 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1040     of strings were treated as being one string containing commas
1041     (fixes #57)
1042 schoenebeck 1244
1043 iliev 959 * Bug fixes:
1044     - fixed crash occurring on certain LSCP scripts (Bug 39)
1045 persson 1038 - another thread safety fix for lscp "load engine" and "set
1046     channel audio output device"
1047 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1048     on a sampler channel with connected MIDI device
1049 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1050     device connected to a sampler channel to number less then or equal
1051     to the index of the port to which the sampler channel is connected.
1052 iliev 1296 - The previous bindings were not been disconnected when altering
1053     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1054     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1055 iliev 1297 - The active stream/voice count statistic was incorrect.
1056 iliev 1298 - notification events were not been sent for some sampler
1057     channel changes
1058 iliev 1305 - added default min and max values to restrict the number of allowed
1059     audio output channels and MIDI input ports
1060 iliev 1306 - the connection to the PCM interface is now closed when destroying
1061     an audio output device
1062 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1063 iliev 959
1064 schoenebeck 1221 * test cases:
1065     - updated and fixed (haven't been touched in a while)
1066    
1067 schoenebeck 937 Version 0.4.0 (24 November 2006)
1068 persson 696
1069 schoenebeck 697 * packaging changes:
1070 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1071     to post-(un)install steps; added devel package for liblinuxsampler;
1072     to linuxsampler.spec (RPM)
1073 schoenebeck 697 - install necessary development header files for allowing 3rd party
1074     applications to link against liblinuxsampler
1075     - liblinuxsampler's API documentation can be generated with 'make docs'
1076     (Doxygen required)
1077 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1078     implementation (currently either an integer math solution or a
1079     di-harmonic approximation), automatic detection can be overriden
1080     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1081     configure script argument though (mandatory for cross-compilation)
1082 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1083     provided some on his own (as CXXFLAGS)
1084 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1085     messages
1086 schoenebeck 852 - added compile time options to allow disabling the various audio and
1087     MIDI drivers
1088 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1089     (patch by Ebrahim Mayat)
1090 schoenebeck 697
1091 persson 696 * Gigasampler format engine:
1092 schoenebeck 738 - extensive synthesis optimization
1093     (reimplementation of EGs and LFO(s), removed synthesis parameter
1094     prerendering and the synthesis parameter matrix in general, splitting
1095     each audio fragment into subfragments now where each subfragment uses
1096 persson 830 constant pitch and filter coefficients. The volume coefficient is
1097     linearly interpolated inside a subfragment, unless
1098     --disable-interpolate-volume is set.)
1099 persson 696 - fine tuning of the EG modulation parameters
1100 persson 729 - improved filter cutoff calculation by adding support for the
1101     following gig parameters: Cutoff freq (used when no cutoff
1102     controller is defined), Control invert, Minimum cutoff, Velocity
1103 persson 791 curve and Velocity range. The keyboard tracking now scales
1104     cutoff frequency instead of resonance.
1105 persson 877 - added support for gig parameter Resonance.
1106 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1107 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1108     which can be overridden with --enable-global-attenuation
1109 persson 783 - EG fixes: made the length of "attack hold" stage more
1110     accurate. Release stage can now start before attack stage
1111 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1112     time now has a minimal value to prevent clicks.
1113 persson 799 - fixed pitch changes larger than one octave
1114 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1115     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1116     all modes can be altered via standard GM messages, that is CC5 for
1117     altering portamento time, CC65 for enabling / disabling portamento
1118     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1119 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1120     parameter) and crossfade
1121 persson 831 - added support for the "attenuation controller threshold" gig
1122     parameter
1123 persson 832 - added smoothing of volume changes caused by control change
1124     messages
1125 persson 865 - sample loop parameters are now taken from the DimensionRegion
1126     instead of the wave chunk
1127     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1128     not equal to a power of two
1129 persson 877 - reimplementation of the filter algorithm. The new filter is more
1130     accurate and supports all gig filter types, including bandreject
1131     and lowpass turbo.
1132 persson 903 - real support for 24 bit samples - samples are not truncated to
1133     16 bits anymore
1134     - support for aftertouch (channel pressure, not polyphonic
1135     aftertouch)
1136 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1137     amplifying from 0)
1138 persson 696
1139 schoenebeck 711 * LSCP server:
1140     - fixed application exit on broken pipe error (fixes bug #20)
1141 iliev 793 - fixed the notification messages delay due to lack of
1142     network activity (fixes bug #26)
1143 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1144     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1145 schoenebeck 711
1146 schoenebeck 838 * audio driver:
1147     - added aRts audio output driver (by no means RT safe)
1148    
1149 schoenebeck 775 * MIDI driver:
1150     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1151     messages several times instead of once
1152 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1153     for events (i.e. for offline rendering based MIDI drivers)
1154 persson 922 - added checks for bad MIDI data
1155 schoenebeck 775
1156 schoenebeck 900 * linuxsampler application:
1157     - show available sampler engine types on startup
1158    
1159 schoenebeck 705 * general changes:
1160     - support for muting sampler channels and solo mode of the same, two new
1161     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1162     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1163     introduced for this, the behavior is the same like on a mixer console
1164 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1165     --enable-process-muted-channels which can be used to enable the
1166     processing of muted channels.
1167 iliev 777 - support for sostenuto pedal
1168 iliev 779 - support for monitoring the total number of active voices
1169 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1170     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1171 persson 835 - fixed some memory management errors
1172 persson 841 - fixed some concurrency problems that could lead to crashes when
1173     LSCP commands were executed
1174 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1175     sampler channel (fixes bug #36)
1176 schoenebeck 705
1177 schoenebeck 692 Version 0.3.3 (15 July 2005)
1178 schoenebeck 686
1179     * packaging changes:
1180     - fixed compilation with gcc 4.0
1181    
1182 schoenebeck 687 * Gigasampler format engine:
1183     - LFO preprocessing was performed even though the respective LFO was
1184     disabled by the instrument patch (minor efficiency fix)
1185 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1186     for volume ramp downs in the same fragment (needed for current voice
1187     stealing implementation) then simply inform the user with a warning
1188     about possible click sounds and reduce the volume ramp down
1189     appropriately instead of cancelling the audio device connection
1190 schoenebeck 687
1191 schoenebeck 677 Version 0.3.2 (24 June 2005)
1192 schoenebeck 609
1193     * packaging changes:
1194     - updated autotools build files to compile on OS X
1195     (conditional compilation of CoreMIDI and MidiShare drivers)
1196 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1197     './configure --disable-asm' (definitely not recommended)
1198 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1199     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1200     (due to 'dist-bzip2' automake option)
1201 schoenebeck 649
1202     * Gigasampler format engine:
1203     - support for the gig parameters for "release velocity response" curves
1204     - fine tuning of the EGADSR envelope
1205     - volume of release triggered samples now depends on note-on velocity,
1206     note length and gig parameter "release trigger decay" instead of
1207     note-off velocity.
1208 schoenebeck 663 - revised voice stealing
1209     (fixes crash and endless loop caused by voice stealing)
1210 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1211 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1212     instead of when the respective voice is actually launched
1213     (fixes undefined behavior if stolen voices belonged to a key group -
1214     this case was followed by a "killed voice survived" error message)
1215 schoenebeck 669 - fixed minor issue with null/silence samples
1216     (those stole voices even though they don't need a voice at all which
1217     resulted in "voice stealing didn't work out" messages)
1218 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1219     instrument or audio output device change
1220 schoenebeck 654
1221 schoenebeck 620 * LSCP server:
1222 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1223 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1224 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1225 schoenebeck 609
1226 schoenebeck 668 * linuxsampler application:
1227     - added command line parameters --lscp-addr and --lscp-port to override
1228     default IP address and port of LSCP server
1229    
1230 schoenebeck 579 Version 0.3.1 (24 May 2005)
1231    
1232     * initial release
