* NKSP Fix: "init" event handler was not always executed when a script
  was loaded.
* NKSP built-in wait() script function: abort script execution if
  a negative or zero wait time was passed as argument (since this is
  a common indication of a bug either of the script or even of the
  engine, which could lead to RT instability or even worse).
* Bumped version (2.0.0.svn24).

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).

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

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

239     key
240 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
241     - bugfix: filter keyboard tracking was broken
242     - filter performance fix (an unnecessary copy was made of the
243     filter parameters in each sub fragment)
244     - handle special case when pan parameter in gig file has max or
245     min value
246 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
247     doesn't sound naturally with a drumkit
248 persson 2408 - fixed EG1 modulation when attack or release is zero
249 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
250 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
251     conditions (see also previous commit on libgig).
252 persson 2673 - fixed behaviour of filter LFO
253 persson 2043

272     - fine-tuned the default velocity curve
273 persson 2086 - added support for transpose
274     - fixed crash when using sw_down/up
275     - improved logic for sw_lokey/hikey/up/down/last
276     - added more v1 aliases to parser
277 persson 2091 - reduced memory usage for sfz data
278 persson 2101 - RT-safeness: avoid malloc in audio thread
279     - fixed a bug that could cause voice stealing to fail
280 persson 2106 - optimized sample lookup
281 persson 2114 - improved support for exclusive groups (group, off_by and
282     off_mode)

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

708 persson 1790 - added memory ordering constraints to improve stability on
709     multi-core and multi-cpu systems
710 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
711 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
712 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
713     be switched on by command line option "--stacktrace" (the automatic
714     stacktrace mechanism seems to be broken on most systems at the moment)
715 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
716     a pointer to the launched InstrumentEditor object
717 schoenebeck 1876 - added optional 3rd party user data parameter for following
718     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
719     InstrumentEditor::Launch(),
720     InstrumentManager::LaunchInstrumentEditor()
721 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
722     model more strictly
723 persson 1895 - fixes for using large audio device buffers
724 persson 1951 - Windows: add the installation directory to the DLL search path

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

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