File size: 68273 byte(s)
* NKSP: Fixed NKSP parser warning "Not a statement" when assigning an
  initializer list to an array variable.
* Bumped version (2.0.0.svn27).

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

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

192 iliev 2296 - experimental support for per voice equalization
193 iliev 2306 - added command line option --exec-after-init
194 schoenebeck 2330 - Introduced new C++ API method:
195     EngineChannel::InstrumentFileName(int index)
196     allowing to retrieve the whole list of files used for the loaded
197     instrument on an engine channel (a.k.a. part). Some GigaStudio
198     instruments for example are splitted over several files like
199     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
200 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
201     - Added new C++ API method Sampler::GetGlobalMaxStreams().
202     - Added new C++ API method Sampler::SetGlobalMaxVoices().
203     - Added new C++ API method Sampler::SetGlobalMaxStreams().
204 schoenebeck 2377 - Various "const" and "restrict" optimizations.
205 persson 2382 - all engines: add pan CC value to instrument pan parameter before
206     applying panning, instead of using two separate pan functions in
207     series (#182)
208 persson 2427 - added a lock guard class for exception safe mutex handling and
209     used it everywhere appropriate
210 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
211     - Exposed scale tuning to C++ API (along to the already existing standard
212     SysEx way).
213 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
214     and broken for ppc64. (Seq_cst loads and stores are actually not
215     used in LS, so the bug wasn't noticable.)
216     - lsatomic.h: added ARMv7 support
217 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
218     added various new C++ methods for this new feature / design change, old
219     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
220     as deprecated but are still there and should provide full behavior
221     backward compatibility).
222     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
223     unsafe and caused compilation error with clang 2.x).
224 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
225 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
226     sampler from the command line by providing LSCP aware features.
227 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
228     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
229     - VirtualMidiDevice: Added support for pitch bend.
230 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
231     polyphonic key pressure events (so far polyphonic pressure was not
232     supported at all, and channel pressure was rerouted as CC128 but not
233     used so far).
234 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
235     code is shared by all sampler engine implemementations, however only the
236     gig file format currently provides support for storing instrument scripts
237     (as LinuxSampler extension to the original GigaStudio 4 format).
238 iliev 2012
239 persson 2043 * Gigasampler format engine:
240     - implemented the "round robin keyboard" dimension
241     - fixed round robin and random dimensions for cases when number of
242     dimension zones is not a power of two
243     - made round robin use a counter for each region instead of each
244     key
245 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
246     - bugfix: filter keyboard tracking was broken
247     - filter performance fix (an unnecessary copy was made of the
248     filter parameters in each sub fragment)
249     - handle special case when pan parameter in gig file has max or
250     min value
251 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
252     doesn't sound naturally with a drumkit
253 persson 2408 - fixed EG1 modulation when attack or release is zero
254 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
255 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
256     conditions (see also previous commit on libgig).

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

277     - fine-tuned the default velocity curve
278 persson 2086 - added support for transpose
279     - fixed crash when using sw_down/up
280     - improved logic for sw_lokey/hikey/up/down/last
281     - added more v1 aliases to parser
282 persson 2091 - reduced memory usage for sfz data

694     (fixes bug #70, patch by Ronald Baljeu)
695 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
696     plugin DLL on Windows systems failed
697 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
698     - optimized the SynchronizedConfig class so it doesn't wait
699     unnecessarily long after an update
700 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
701     events (e.g. to highlight the pressed keys on the virtual keyboard
702     of gigedit)
703 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
704 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
705 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
706     is only used by very few systems, most pick the int math
707     implementation, which is usually faster)
708 persson 1748 - fixes for audio drivers with varying buffer sizes
709 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
710     VST plugin
711 iliev 1789 - notification events for stream/voice count statistics are now sent
712     only when there are actual changes
713 persson 1790 - added memory ordering constraints to improve stability on
714     multi-core and multi-cpu systems
715 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
716 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
717 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
718     be switched on by command line option "--stacktrace" (the automatic
719     stacktrace mechanism seems to be broken on most systems at the moment)
720 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
721     a pointer to the launched InstrumentEditor object
722 schoenebeck 1876 - added optional 3rd party user data parameter for following
723     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
724     InstrumentEditor::Launch(),
725     InstrumentManager::LaunchInstrumentEditor()
726 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
727     model more strictly
728 persson 1895 - fixes for using large audio device buffers
729 persson 1951 - Windows: add the installation directory to the DLL search path
730     when loading an editor plugin (solves problems with VST and
731     gigedit on systems with other GTK versions installed)
732 schoenebeck 2509 - updated linuxsampler man page
733 schoenebeck 1601
734 schoenebeck 1599 * audio driver:
735     - removed the nonsense audio channel constraint (which was hard coded to
736     max. 100 audio channels) for most audio drivers
737 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
738     opposed to the LSCP specs
739 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
740     reflected the wrong value
741 persson 1644 - fixed a memory management bug in ASIO driver
742 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
743 persson 1777 - JACK: use jack_client_open instead of the deprecated
744 persson 1748 jack_client_new
745 iliev 1829 - added (experimental) CoreAudio driver
746 persson 1888 - applied old fixes to the ASIO driver that were included in the
747     previous binary release but accidentally never committed to CVS
748     (fixes #117)
749 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
750     win64)
751 persson 1895 - VST: added support for sample rate and buffer size changes
752     - VST: close editor (Fantasia) when the VST is removed

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