* NKSP: Provide more user friendly error messages on syntax errors.
* Bumped version (2.0.0.svn26).

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.

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

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

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

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

275     - fine-tuned the default velocity curve
276 persson 2086 - added support for transpose
277     - fixed crash when using sw_down/up
278     - improved logic for sw_lokey/hikey/up/down/last
279     - added more v1 aliases to parser
280 persson 2091 - reduced memory usage for sfz data
281 persson 2101 - RT-safeness: avoid malloc in audio thread
282     - fixed a bug that could cause voice stealing to fail

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

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