File size: 68404 byte(s)
* gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
  properly and thus were ignored for certain uses.
* Bumped version (2.0.0.svn28).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5    
6 persson 2837 * general changes:
7     - fixed printf type errors (mostly in debug messages)
8 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
9 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10     allowing to sort data efficiently in real-time safe manner.
11     - RTList class: added methods for moving/inserting elements to arbitrary
12     position within a list.
13     - RTList class: added method fromPtr() for creating an Iterator object from
14     a raw element pointer.
15     - Attempt to partly fix resetting engine channels vs. resetting engine, an
16     overall cleanup of the Reset*(), ConnectAudioDevice(),
17     DisconnectAudioDevice() API methods would still be desirable though,
18     because the current situation is still inconsistent and error prone.
19 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
20     being directly assigned to a keyboard key. This allows more fine graded
21     processing of voices, which is i.e. required for certain instrument
22     script features.
23 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
24     (CC #64) events.
25     - Fix: Release trigger voices can now also distinguish correctly between
26     note-off and sustain pedal up events.
27 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
28     (while slow rate of crossfade smoother is preserved) to allow quick
29     volume and pan changes by instrument scripts for instance.
30 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31     properly and thus were ignored for certain uses.
32 persson 2837
33 schoenebeck 2866 * packaging changes:
34     - removed unnecessary dependency to libuuid
35     (originated by libgig's usage of it)
36 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
37     auto detect whether it (sh/c)ould output its messages in color.
38 schoenebeck 2866
39 schoenebeck 2871 * Real-time instrument scripts:
40     - Implemented scheduler for delayed MIDI events and for suspended scripts.
41     - Built-in script function "wait()": implemented support for function's
42     "duration-us" argument, thus scripts using this function are now
43     correctly resumed after the requested amount of microseconds.
44     - Built-in script function "play_note()": implemented support for
45     function's "duration-us" argument, thus notes triggered with this
46     argument are now correctly released after the requested amount of
47     microseconds.
48     - Fix: script events were not cleared when engine channel was reset,
49     potentially causing undefined behavior.
50     - Fixed crash which happened when trying to reference an undeclared
51     variable.
52 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
53     special value -1 for "duration-us" argument, which will cause the
54     triggered note to be released once the original note was released.
55 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
56     - Added new API method ScriptVM::syntaxHighlighting() which provides
57     a convenient syntax highlighting backend for external instrument
58     script editor applications.
59 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
60     - Extended parser issues to provide not only first line and first
61     column, but also last line and last column of issue (thus marking
62     the precise span of the issue within the source code).
63 schoenebeck 2902 - Reload script automatically after being modified by an instrument
64     editor.
65 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
66     like "on note end on".
67 schoenebeck 2931 - Implemented built-in script function "change_vol()".
68     - Implemented built-in script function "change_tune()".
69     - Implemented built-in script function "change_pan()".
70 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
71     - Implemented built-in script function "change_reso()".
72     - Implemented built-in script function "event_status()".
73     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
74     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
75     "event_status()" function.
76     - NKSP language: Added support for bitwise operators ".or.", ".and."
77     and ".not.".
78     - NKSP language scanner: Fixed IDs matching to require at least one
79     character (i.e. when matching function names or variable names).
80     - NKSP language scanner: disabled unusued rules.
81 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
82     be distinguished engine internally from "real" MIDI note on/off
83     events in order to avoid misbehaviors like hanging notes.
84 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
85     - Implemented built-in script variable "$NKSP_REAL_TIMER".
86     - Implemented built-in script variable "$NKSP_PERF_TIMER".
87     - Implemented built-in script variable "$ENGINE_UPTIME".
88 schoenebeck 2945 - Implemented built-in script function "inc()".
89     - Implemented built-in script function "dec()".
90     - NKSP language fix: division expressions were evaluated too often.
91     - NKSP language fix: string concatenation operator was right
92     associative instead of left (to right).
93 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
94     (i.e. "if end if").
95 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
96     - Implemented built-in script variable "$NI_CALLBACK_ID".
97     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
98     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
99     - Added support for read-only built-in variables (respectively
100     handled by the script parser).
101     - Added built-in script constant "$NI_CB_TYPE_INIT".
102     - Added built-in script constant "$NI_CB_TYPE_NOTE".
103     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
104     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
105 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
106 schoenebeck 2953 - Implemented built-in script function "change_attack()".
107     - Implemented built-in script function "change_decay()".
108     - Implemented built-in script function "change_release()".
109 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
110     synthesis parameter changes immediately in case the respective note
111     was triggered at the same time, instead of scheduling the parameter
112     change, especially because it would cause some parameter types's
113     changes either to be ramped (i.e. change_vol()) or other types even
114     to have not effect at all (i.e. change_attack()).
115 schoenebeck 2965 - Implemented built-in script function "sh_left()".
116     - Implemented built-in script function "sh_right()".
117 schoenebeck 2970 - Implemented built-in script function "min()".
118     - Implemented built-in script function "max()".
119 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
120     was loaded.
121     - NKSP built-in wait() script function: abort script execution if
122     a negative or zero wait time was passed as argument (since this is
123     a common indication of a bug either of the script or even of the
124     engine, which could lead to RT instability or even worse).
125 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
126     threatening scripts.
127 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
128 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
129     initializer list to an array variable.

169     in order to get rid of warnings from automake 1.14
170 persson 2382
171 persson 2086 * general changes:
172 iliev 2012 - Refactoring: moved the independent code from
173     the Gigasampler format engine to base classes
174 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
175     respective profiling code is currently broken
176 schoenebeck 2053 - Introduced support for optional environment variable
177     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
178     where the sampler shall look for instrument editor plugins
179     (patch by Luis Garrido, slightly modified).
180 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
181     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
182     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
183     note (in this implementation of the sampler its simply hard routed to
184     the 1st effect send of the sampler channel, no matter what the actual
185     effect type is)
186     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
187     note (in this implementation of the sampler its simply hard routed to
188     the 2nd effect send of the sampler channel, no matter what the actual
189     effect type is)
190 schoenebeck 2124 - implemented support for internal LADSPA effects
191 schoenebeck 2140 - raised limit of program change queue from 100 to 512
192     (as suggested by Alex Stone)

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

246     key
247 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
248     - bugfix: filter keyboard tracking was broken
249     - filter performance fix (an unnecessary copy was made of the
250     filter parameters in each sub fragment)
251     - handle special case when pan parameter in gig file has max or
252     min value
253 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
254     doesn't sound naturally with a drumkit
255 persson 2408 - fixed EG1 modulation when attack or release is zero
256 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
257 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
258     conditions (see also previous commit on libgig).

265     one from the gig engine
266 persson 2058 - fixed memory leak and memory handling errors
267 persson 2061 - added support for trigger=first, trigger=legato and sw_previous

281     - fixed crash when using sw_down/up
282     - improved logic for sw_lokey/hikey/up/down/last
283     - added more v1 aliases to parser
284 persson 2091 - reduced memory usage for sfz data

695     load as we used a non-portable Linux specific struct field
696     (fixes bug #70, patch by Ronald Baljeu)
697 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
698     plugin DLL on Windows systems failed
699 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
700     - optimized the SynchronizedConfig class so it doesn't wait
701     unnecessarily long after an update
702 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
703     events (e.g. to highlight the pressed keys on the virtual keyboard
704     of gigedit)
705 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
706 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
707 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
708     is only used by very few systems, most pick the int math
709     implementation, which is usually faster)
710 persson 1748 - fixes for audio drivers with varying buffer sizes
711 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
712     VST plugin
713 iliev 1789 - notification events for stream/voice count statistics are now sent

717 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
718 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
719 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
720     be switched on by command line option "--stacktrace" (the automatic
721     stacktrace mechanism seems to be broken on most systems at the moment)
722 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
723     a pointer to the launched InstrumentEditor object
724 schoenebeck 1876 - added optional 3rd party user data parameter for following
725     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
726     InstrumentEditor::Launch(),
727     InstrumentManager::LaunchInstrumentEditor()
728 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
729     model more strictly
730 persson 1895 - fixes for using large audio device buffers
731 persson 1951 - Windows: add the installation directory to the DLL search path

734 schoenebeck 2509 - updated linuxsampler man page
735 schoenebeck 1601
736 schoenebeck 1599 * audio driver:
737     - removed the nonsense audio channel constraint (which was hard coded to
738     max. 100 audio channels) for most audio drivers
739 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
740     opposed to the LSCP specs
741 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
742     reflected the wrong value
743 persson 1644 - fixed a memory management bug in ASIO driver
744 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
745 persson 1777 - JACK: use jack_client_open instead of the deprecated
746 persson 1748 jack_client_new
747 iliev 1829 - added (experimental) CoreAudio driver
748 persson 1888 - applied old fixes to the ASIO driver that were included in the
749     previous binary release but accidentally never committed to CVS
750     (fixes #117)
751 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
752     win64)
753 persson 1895 - VST: added support for sample rate and buffer size changes
754     - VST: close editor (Fantasia) when the VST is removed
755 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

759     stereo
760 persson 1922 - added channel routing, fxsends and midi maps to the settings
761     stored in the plugin state
762 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
763     AudioChannel::CopyTo() methods using GCC vector exensions
764     (if available)
765 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
766     exception when getting parameters from a disconnected device
767 schoenebeck 1599
768 persson 1651 * MIDI driver:
769     - added JACK MIDI driver
770 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
771     want to (mis)use it for some purpose ("fixed" in all current MIDI
772     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
773 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
774 persson 1887 CoreMidi or AU
775 persson 1889 - fixed mingw-w64 compilation error in MME driver
776 persson 1924 - made program change handling in MIDI thread real-time safe by
777     moving the logic to a non-RT thread
778 persson 1951 - fixed minor memory leak in ALSA driver
779 persson 1651
780 schoenebeck 1604 * instruments database:
781 iliev 1603 - avoid time consuming samples scanning when adding instruments
782     to the instruments database
783 iliev 1727 - added support for handling lost files in the instruments database
784 iliev 1781 - Implemented option for adding instruments in separate directories
785     in the instruments database
786     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
787 persson 1908 - work-around for missing fnmatch function on Windows to make
788     instrument database compilable
789 schoenebeck 1930 - added instrument database support on Windows
790     works with both standalone mode and VST plugin.
791     the instruments DB file is located in
792     %USERPROFILE%\.linuxsampler\instruments.db which allows different
793     databases for each windows user
794     if no DB is present it automatically creates the .linuxsampler subdir
795     and then creates an empty DB
796 persson 1943 - fixed recursive import, which was broken on Windows
797 iliev 1603
798 persson 1644 * Gigasampler format engine:
799     - fixed a memory leak that could happen when a channel was deleted
800     while notes were playing
801 persson 1646 - made it possible to load an instrument even if the audio thread
802     isn't running
803 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
804     enough for piano gigs with pedal noise samples
805 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
806     respective FX send MIDI controller was used
807 schoenebeck 1724 - added support for GM global device volume SysEx message
808 schoenebeck 1762 (can be selected at compile time to either apply globally to the
809     whole sampler [default] or only to the sampler channels that are
810     connected to the respective MIDI input port the SysEx message arrived
811     on)
812 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
813     sometimes wrongly killed in the same buffer, causing no sound to
814     be played
815 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
816     which is usally used to switch a part between chromatic sounds and
817     drumkit sounds (as opposed to their common default setting of MIDI
818     part 10 being a drumkit part and all other ones chromatic parts), in
819     LS however one can switch between the first 16 MIDI instrument maps
820     defined for the sampler
821 persson 1764 - made it possible to create multiple sample channels even if the
822     audio thread isn't running
823 persson 1844 - fixed crash when removing channel with active voices (#116)
824 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
825     un-cache the respective sample if it's really not used by any
826     sampler engine anymore
827     - re-cache samples in case they were changed by an instrument editor,
828     e.g. when a sample was added while playing (#82)
829 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
830     same time stamp as the voice's note-on event and occured both in the
831     same audio fragment cycle (fixes bug #112)
832 persson 1858 - added support for the "fine tune" and "pitch bend range"
833     instrument-level gig parameters
834     - fixed minor artifacts in pitch bend handling
835 schoenebeck 1860 - added support for GS Reset SysEx message
836 persson 1862 - allow gig files to use unlimited downward pitch shifting
837     - added a limit check for upward pitch shifting
838 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
839     note was silent
840 persson 1923 - fixed crash happening when a pitch bend event arrived at the
841     same time a new instrument was loading
842 persson 1644
843 schoenebeck 1687 * LSCP server:
844     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
845     react on MIDI data arriving on certain sampler channels (so far only
846     Note-On and Note-Off events are sent via this LSCP event)
847 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
848     react on MIDI data arriving on certain MIDI input devices (so far only
849     Note-On and Note-Off events are sent via this LSCP event)
850 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
851     SET DB_INSTRUMENT FILE_PATH
852 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
853     frontends to send MIDI messages to specific sampler channel
854     - added two additional fields to GET FILE INSTRUMENT INFO command -
855     KEY_BINDINGS and KEYSWITCH_BINDINGS
856 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
857     was incorrect
858 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
859 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
860     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
861     be triggered respectively
862     - added new LSCP command "SET STREAMS" to globally alter the maximum
863     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
864     which will be triggered respectively
865 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
866     a gigedit file dialog is opened)
867 iliev 1848 - close all connections when LSCPServer is deleted
868 iliev 1882 - hard close of all sockets on exit
869 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
870     driver
871 schoenebeck 1687
872 iliev 1761 * Bug fixes:
873     - fixed a crash which occurs when removing a sampler channel waiting
874     to start instrument loading after another channel
875 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
876     instrument loading in progress (bug #113)
877 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
878     instrument with PERSISTENT load mode
879 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
880     - fixed memory leaks when issuing the following LSCP commands:
881     GET AUDIO_OUTPUT_DRIVER INFO
882     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
883     GET MIDI_INPUT_DRIVER INFO
884     GET MIDI_INPUT_DRIVER_PARAMETER INFO
885     - fixed possible compilation error when sqlite is not present
886 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
887 iliev 1847 - fixed crash when changing the audio output device of a sampler
888     channel with loaded instrument and start playing notes
889 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
890 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
891     PowerPC, which probably could cause crashes on that platform
892 persson 1889 - fixed a memory management error which could cause a crash when a
893     plugin was unloaded
894 persson 1896 - bugfix: two private structs had the same name, which could cause
895     problems if the linker chose the wrong constructor
896 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
897     Windows
898 iliev 1761
899    
900 schoenebeck 1560 Version 0.5.1 (6 December 2007)
901 schoenebeck 1454
902     * packaging changes:
903     - added autoconf checks for pthread library
904     - added autoconf check for pthread bug found on certain NPTL-enabled
905     glibc versions (see Gentoo bug report #194076)
906 senoner 1502 - added autoconf checks for MS Windows
907 schoenebeck 1454
908 persson 1455 * general changes:
909     - bugfix: the thread used by an editor plugin didn't die when the
910     editor closed
911 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
912     out all the space. operator--() did not apply size_mask after
913     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
914     order to avoid problems with the _NonVolatileReader functions.
915     - bugfix: Stream.h: added a missing divide by BytesPerSample in
916     GetWriteSpace(). Since this function is currently only used in
917     the stream's qsort() compare function, it didn't trigger any
918     bugs.
919     - Resampler.h, Synthesizer.h: cubic interpolation now works in
920     24bit mode too. Faster method to read 24bit words on little
921     endian machines (x86): replaced 3 byte reads + shifts with a 1
922     unaligned 32bit read and shift
923     - experimental support for MS Windows (MIDI input via MME, AUDIO
924     output via ASIO)
925     - made handling of SIGINT signal (Ctrl-C) a bit more robust
926 iliev 1541 - support for monitoring the total number of active disk streams
927     (new LSCP commands: GET TOTAL_STREAM_COUNT,
928     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
929 persson 1455
930 senoner 1500 * AUDIO driver:
931 persson 1534 - added Windows ASIO low latency audio driver
932 senoner 1500
933 senoner 1485 * MIDI driver:
934 schoenebeck 1495 - added MME Windows MIDI driver
935 senoner 1485
936 schoenebeck 1471 * LSCP server:
937     - added support for Windows style path / filenames, however with
938     forward slash path separators instead of backslash
939     (i.e. "C:/foo/bar.gig")
940 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
941     apostrophes as well
942 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
943     "LIST FILE INSTRUMENTS <file>" and
944     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
945     about an arbitrary instrument file on the system where the sampler is
946     running on
947 schoenebeck 1471
948 schoenebeck 1424 Version 0.5.0 (15 October 2007)
949 schoenebeck 947
950 schoenebeck 1065 * packaging changes:
951 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
952     API header files anymore
953 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
954     the Doxygen API documentation (explicitly listed in Doxyfile.in)
955 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
956     capable to execute our autoconf environment, thus no need anymore
957     to maintain the compile time configuration file (osx/version.h) for
958     OSX manually (patch by Toshi Nagata)
959 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
960     parameters
961 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
962     C++ API header files, all implementation internal global definitions
963     are now in global_private.h
964     - atomic.h is not exposed to the C++ API anymore
965     - no need to include config.h anymore for using LS's API header files
966     - fixed warnings in API doc generation
967 schoenebeck 1065
968 schoenebeck 947 * general changes:
969     - replaced the old, confusing MIDI program change mechanism by a
970     flexible MIDI instrument mapper which allows to map arbitrary
971 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
972 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
973     loaded on the respective channel when such MIDI program change
974     messages arrive, beside that, each entry allows to define a life-time
975     strategy for the instrument, so the user can define whether the
976     instrument should i.e. be permanently loaded (to be able to switch
977     quickly among sounds) or i.e. loaded just on demand when the
978     respective program change arrives (to safe RAM space), as well as a
979     global volume factor for each entry, so the user can adjust the volume
980     dynamic of his mapped instrument collection without having to modify
981 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
982     MIDI instrument maps and assign each sampler channel individually
983     a certain map, so that i.e. separation of normal instruments and
984     drumkits is possible
985 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
986     MIDI instrument maps, MIDI instruments, FX sends, global volume.
987 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
988     due to a constant size RingBuffer FIFO which is now replaced by a
989     dynamic (unlimited) size std::list FIFO
990 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
991     output channels for being processed by external effect processors
992     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
993     controllers
994 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
995 iliev 1130 - Implemented new, improved notification system
996 schoenebeck 1149 - fixed compilation errors regarding OSX
997     (patch by Toshi Nagata)
998 iliev 1161 - implemented instruments database
999 iliev 1345 - added support for escape sequences to the instruments database
1000 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1001     within the sampler's process (by using instrument editor plugins),
1002     you'll notice the new "Registered instrument editors:" message on
1003 schoenebeck 1407 startup, added a new LSCP command:
1004     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1005 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1006     given sampler channel, the plugin path can be overridden at compile
1007     time with ./configure --enable-plugin-dir=/some/dir
1008 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1009     in the sampler's process to safely edit instruments while playing
1010     without a crash (hopefully) by either suspending single regions
1011     wherever possible or if unavoidable whole engine(s)
1012 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1013     policy and priority on thread level, set a minimum stack size for
1014     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1015     threads simply inherited properties of starting thread instead of
1016     setting their own policy and priority
1017 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1018     main process did not wait for the stack trace process to finish
1019     its output
1020 persson 1248 - fixed some minor memory leaks
1021 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1022     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1023 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1024     register, to avoid relocations in the text segment at runtime)
1025 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1026 schoenebeck 947
1027     * MIDI driver:
1028     - dispatch bank select (MSB and LSB) messages
1029    
1030 schoenebeck 1049 * audio driver:
1031     - the ALSA audio output driver parameters now reflect the correct
1032     parameter value ranges for the respective selected sound card
1033     (patch by Till Wimmer, a bit fixed and extended)
1034    
1035 persson 951 * Gigasampler format engine:
1036     - if a filter is used and EG2 finishes before EG1, let the voice
1037     die when EG2 has finished (this fixes a problem with clicks and
1038     voice starvation for some gigs)
1039 persson 1038 - playback is no longer disabled during instrument loading
1040     - all notes playing on a channel that changes its instrument keep
1041     playing with the old instrument until they get a note off
1042     command
1043 persson 1039 - EG fix: a release value of zero could cause noises or crash
1044 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1045 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1046     above max sustain level, which means that there is a decay phase
1047     even if sustain is 100%
1048 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1049     noises or crashes
1050 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1051 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1052     supplied to the configure script (fixes #46)
1053 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1054     instead of a fix value
1055 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1056     127 (solo mode) only kill voices if the respective mode really
1057     changed
1058 persson 951
1059 schoenebeck 1244 * LSCP server:
1060     - fixed compile time error for old Bison versions
1061     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1062 schoenebeck 1245 - parser now supports extended ASCII character set
1063     (up to ASCII code 255, i.e. includes now umlauts and accents)
1064     - filename arguments in LSCP commands now allow to use escape
1065     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1066     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1067     code value like \xf2) (fixes bug #24)
1068 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1069     least one of their text-based parameters (i.e. name, description):
1070     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1071     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1072     "SET DB_INSTRUMENT_DIRECTORY NAME",
1073     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1074     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1075     "FIND DB_INSTRUMENT_DIRECTORIES"
1076 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1077     occured, the unexpected character and the actually expected, possible
1078     character(s), the latter only if less than 5 possibilities)
1079 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1080     settings
1081 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1082     of strings were treated as being one string containing commas
1083     (fixes #57)
1084 schoenebeck 1244
1085 iliev 959 * Bug fixes:
1086     - fixed crash occurring on certain LSCP scripts (Bug 39)
1087 persson 1038 - another thread safety fix for lscp "load engine" and "set
1088     channel audio output device"
1089 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1090     on a sampler channel with connected MIDI device
1091 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1092     device connected to a sampler channel to number less then or equal
1093     to the index of the port to which the sampler channel is connected.
1094 iliev 1296 - The previous bindings were not been disconnected when altering
1095     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1096     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1097 iliev 1297 - The active stream/voice count statistic was incorrect.
1098 iliev 1298 - notification events were not been sent for some sampler
1099     channel changes
1100 iliev 1305 - added default min and max values to restrict the number of allowed
1101     audio output channels and MIDI input ports
1102 iliev 1306 - the connection to the PCM interface is now closed when destroying
1103     an audio output device
1104 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1105 iliev 959
1106 schoenebeck 1221 * test cases:
1107     - updated and fixed (haven't been touched in a while)
1108    
1109 schoenebeck 937 Version 0.4.0 (24 November 2006)
1110 persson 696
1111 schoenebeck 697 * packaging changes:
1112 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1113     to post-(un)install steps; added devel package for liblinuxsampler;
1114     to linuxsampler.spec (RPM)
1115 schoenebeck 697 - install necessary development header files for allowing 3rd party
1116     applications to link against liblinuxsampler
1117     - liblinuxsampler's API documentation can be generated with 'make docs'
1118     (Doxygen required)
1119 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1120     implementation (currently either an integer math solution or a
1121     di-harmonic approximation), automatic detection can be overriden
1122     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1123     configure script argument though (mandatory for cross-compilation)
1124 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1125     provided some on his own (as CXXFLAGS)
1126 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1127     messages
1128 schoenebeck 852 - added compile time options to allow disabling the various audio and
1129     MIDI drivers
1130 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1131     (patch by Ebrahim Mayat)
1132 schoenebeck 697
1133 persson 696 * Gigasampler format engine:
1134 schoenebeck 738 - extensive synthesis optimization
1135     (reimplementation of EGs and LFO(s), removed synthesis parameter
1136     prerendering and the synthesis parameter matrix in general, splitting
1137     each audio fragment into subfragments now where each subfragment uses
1138 persson 830 constant pitch and filter coefficients. The volume coefficient is
1139     linearly interpolated inside a subfragment, unless
1140     --disable-interpolate-volume is set.)
1141 persson 696 - fine tuning of the EG modulation parameters
1142 persson 729 - improved filter cutoff calculation by adding support for the
1143     following gig parameters: Cutoff freq (used when no cutoff
1144     controller is defined), Control invert, Minimum cutoff, Velocity
1145 persson 791 curve and Velocity range. The keyboard tracking now scales
1146     cutoff frequency instead of resonance.
1147 persson 877 - added support for gig parameter Resonance.
1148 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1149 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1150     which can be overridden with --enable-global-attenuation
1151 persson 783 - EG fixes: made the length of "attack hold" stage more
1152     accurate. Release stage can now start before attack stage
1153 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1154     time now has a minimal value to prevent clicks.
1155 persson 799 - fixed pitch changes larger than one octave
1156 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1157     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1158     all modes can be altered via standard GM messages, that is CC5 for
1159     altering portamento time, CC65 for enabling / disabling portamento
1160     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1161 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1162     parameter) and crossfade
1163 persson 831 - added support for the "attenuation controller threshold" gig
1164     parameter
1165 persson 832 - added smoothing of volume changes caused by control change
1166     messages
1167 persson 865 - sample loop parameters are now taken from the DimensionRegion
1168     instead of the wave chunk
1169     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1170     not equal to a power of two
1171 persson 877 - reimplementation of the filter algorithm. The new filter is more
1172     accurate and supports all gig filter types, including bandreject
1173     and lowpass turbo.
1174 persson 903 - real support for 24 bit samples - samples are not truncated to
1175     16 bits anymore
1176     - support for aftertouch (channel pressure, not polyphonic
1177     aftertouch)
1178 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1179     amplifying from 0)
1180 persson 696
1181 schoenebeck 711 * LSCP server:
1182     - fixed application exit on broken pipe error (fixes bug #20)
1183 iliev 793 - fixed the notification messages delay due to lack of
1184     network activity (fixes bug #26)
1185 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1186     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1187 schoenebeck 711
1188 schoenebeck 838 * audio driver:
1189     - added aRts audio output driver (by no means RT safe)
1190    
1191 schoenebeck 775 * MIDI driver:
1192     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1193     messages several times instead of once
1194 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1195     for events (i.e. for offline rendering based MIDI drivers)
1196 persson 922 - added checks for bad MIDI data
1197 schoenebeck 775
1198 schoenebeck 900 * linuxsampler application:
1199     - show available sampler engine types on startup
1200    
1201 schoenebeck 705 * general changes:
1202     - support for muting sampler channels and solo mode of the same, two new
1203     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1204     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1205     introduced for this, the behavior is the same like on a mixer console
1206 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1207     --enable-process-muted-channels which can be used to enable the
1208     processing of muted channels.
1209 iliev 777 - support for sostenuto pedal
1210 iliev 779 - support for monitoring the total number of active voices
1211 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1212     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1213 persson 835 - fixed some memory management errors
1214 persson 841 - fixed some concurrency problems that could lead to crashes when
1215     LSCP commands were executed
1216 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1217     sampler channel (fixes bug #36)
1218 schoenebeck 705
1219 schoenebeck 692 Version 0.3.3 (15 July 2005)
1220 schoenebeck 686
1221     * packaging changes:
1222     - fixed compilation with gcc 4.0
1223    
1224 schoenebeck 687 * Gigasampler format engine:
1225     - LFO preprocessing was performed even though the respective LFO was
1226     disabled by the instrument patch (minor efficiency fix)
1227 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1228     for volume ramp downs in the same fragment (needed for current voice
1229     stealing implementation) then simply inform the user with a warning
1230     about possible click sounds and reduce the volume ramp down
1231     appropriately instead of cancelling the audio device connection
1232 schoenebeck 687
1233 schoenebeck 677 Version 0.3.2 (24 June 2005)
1234 schoenebeck 609
1235     * packaging changes:
1236     - updated autotools build files to compile on OS X
1237     (conditional compilation of CoreMIDI and MidiShare drivers)
1238 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1239     './configure --disable-asm' (definitely not recommended)
1240 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1241     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1242     (due to 'dist-bzip2' automake option)
1243 schoenebeck 649
1244     * Gigasampler format engine:
1245     - support for the gig parameters for "release velocity response" curves
1246     - fine tuning of the EGADSR envelope
1247     - volume of release triggered samples now depends on note-on velocity,
1248     note length and gig parameter "release trigger decay" instead of
1249     note-off velocity.
1250 schoenebeck 663 - revised voice stealing
1251     (fixes crash and endless loop caused by voice stealing)
1252 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1253 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1254     instead of when the respective voice is actually launched
1255     (fixes undefined behavior if stolen voices belonged to a key group -
1256     this case was followed by a "killed voice survived" error message)
1257 schoenebeck 669 - fixed minor issue with null/silence samples
1258     (those stole voices even though they don't need a voice at all which
1259     resulted in "voice stealing didn't work out" messages)
1260 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1261     instrument or audio output device change
1262 schoenebeck 654
1263 schoenebeck 620 * LSCP server:
1264 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1265 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1266 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1267 schoenebeck 609
1268 schoenebeck 668 * linuxsampler application:
1269     - added command line parameters --lscp-addr and --lscp-port to override
1270     default IP address and port of LSCP server
1271    
1272 schoenebeck 579 Version 0.3.1 (24 May 2005)
1273    
1274     * initial release
