File size: 69027 byte(s)
* Gig Engine: Fixed clicks and pumping noise with Lowpass Turbo filter
  on very low cutoff settings.
* Bumped version (2.0.0.svn34).

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 schoenebeck 3072 * Gigasampler format engine:
7     - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
8     cutoff settings.
9    
10 persson 2837 * general changes:
11     - fixed printf type errors (mostly in debug messages)
12 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
13 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
14     allowing to sort data efficiently in real-time safe manner.
15     - RTList class: added methods for moving/inserting elements to arbitrary
16     position within a list.
17     - RTList class: added method fromPtr() for creating an Iterator object from
18     a raw element pointer.
19     - Attempt to partly fix resetting engine channels vs. resetting engine, an
20     overall cleanup of the Reset*(), ConnectAudioDevice(),
21     DisconnectAudioDevice() API methods would still be desirable though,
22     because the current situation is still inconsistent and error prone.
23 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
24     being directly assigned to a keyboard key. This allows more fine graded
25     processing of voices, which is i.e. required for certain instrument
26     script features.
27 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
28     (CC #64) events.
29     - Fix: Release trigger voices can now also distinguish correctly between
30     note-off and sustain pedal up events.
31 schoenebeck 2963 - All engines: Increased ramp speed of volume smoother and pan smoother
32     (while slow rate of crossfade smoother is preserved) to allow quick
33     volume and pan changes by instrument scripts for instance.
34 schoenebeck 3015 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
35     properly and thus were ignored for certain uses.
36 schoenebeck 3018 - Added new C++ API method
37     VirtualMidiDevice::SendChannelPressureToSampler().
38 persson 3020 - windows, 32-bit: fixed potential crashes by making sure the stack in
39     sub threads is 16-byte aligned
40 schoenebeck 3054 - fixed numerous compiler warnings
41 persson 2837
42 schoenebeck 2866 * packaging changes:
43     - removed unnecessary dependency to libuuid
44     (originated by libgig's usage of it)
45 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
46     auto detect whether it (sh/c)ould output its messages in color.
47 schoenebeck 2866
48 schoenebeck 2871 * Real-time instrument scripts:
49     - Implemented scheduler for delayed MIDI events and for suspended scripts.
50     - Built-in script function "wait()": implemented support for function's
51     "duration-us" argument, thus scripts using this function are now
52     correctly resumed after the requested amount of microseconds.
53     - Built-in script function "play_note()": implemented support for
54     function's "duration-us" argument, thus notes triggered with this
55     argument are now correctly released after the requested amount of
56     microseconds.
57     - Fix: script events were not cleared when engine channel was reset,
58     potentially causing undefined behavior.
59     - Fixed crash which happened when trying to reference an undeclared
60     variable.
61 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
62     special value -1 for "duration-us" argument, which will cause the
63     triggered note to be released once the original note was released.
64 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
65     - Added new API method ScriptVM::syntaxHighlighting() which provides
66     a convenient syntax highlighting backend for external instrument
67     script editor applications.
68 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
69     - Extended parser issues to provide not only first line and first
70     column, but also last line and last column of issue (thus marking
71     the precise span of the issue within the source code).
72 schoenebeck 2902 - Reload script automatically after being modified by an instrument
73     editor.
74 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
75     like "on note end on".
76 schoenebeck 2931 - Implemented built-in script function "change_vol()".
77     - Implemented built-in script function "change_tune()".
78     - Implemented built-in script function "change_pan()".
79 schoenebeck 2935 - Implemented built-in script function "change_cutoff()".
80     - Implemented built-in script function "change_reso()".
81     - Implemented built-in script function "event_status()".
82     - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
83     "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
84     "event_status()" function.
85     - NKSP language: Added support for bitwise operators ".or.", ".and."
86     and ".not.".
87     - NKSP language scanner: Fixed IDs matching to require at least one
88     character (i.e. when matching function names or variable names).
89     - NKSP language scanner: disabled unusued rules.
90 schoenebeck 2938 - Fixed behavior of play_note() and note_off() functions which must
91     be distinguished engine internally from "real" MIDI note on/off
92     events in order to avoid misbehaviors like hanging notes.
93 schoenebeck 2942 - Implemented built-in script variable "$KSP_TIMER".
94     - Implemented built-in script variable "$NKSP_REAL_TIMER".
95     - Implemented built-in script variable "$NKSP_PERF_TIMER".
96     - Implemented built-in script variable "$ENGINE_UPTIME".
97 schoenebeck 2945 - Implemented built-in script function "inc()".
98     - Implemented built-in script function "dec()".
99     - NKSP language fix: division expressions were evaluated too often.
100     - NKSP language fix: string concatenation operator was right
101     associative instead of left (to right).
102 schoenebeck 2947 - NKSP language correction: allow empty statements in entire language
103     (i.e. "if end if").
104 schoenebeck 2948 - Implemented built-in script function "stop_wait()".
105     - Implemented built-in script variable "$NI_CALLBACK_ID".
106     - Implemented built-in script variable "$NI_CALLBACK_TYPE".
107     - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
108     - Added support for read-only built-in variables (respectively
109     handled by the script parser).
110     - Added built-in script constant "$NI_CB_TYPE_INIT".
111     - Added built-in script constant "$NI_CB_TYPE_NOTE".
112     - Added built-in script constant "$NI_CB_TYPE_RELEASE".
113     - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
114 schoenebeck 2951 - NKSP Language: Added support for user defined script functions.
115 schoenebeck 2953 - Implemented built-in script function "change_attack()".
116     - Implemented built-in script function "change_decay()".
117     - Implemented built-in script function "change_release()".
118 schoenebeck 2962 - Fixed all change_*() built-in script functions to apply their
119     synthesis parameter changes immediately in case the respective note
120     was triggered at the same time, instead of scheduling the parameter
121     change, especially because it would cause some parameter types's
122     changes either to be ramped (i.e. change_vol()) or other types even
123     to have not effect at all (i.e. change_attack()).
124 schoenebeck 2965 - Implemented built-in script function "sh_left()".
125     - Implemented built-in script function "sh_right()".
126 schoenebeck 2970 - Implemented built-in script function "min()".
127     - Implemented built-in script function "max()".
128 schoenebeck 2972 - NKSP Fix: "init" event handler was not always executed when a script
129     was loaded.
130     - NKSP built-in wait() script function: abort script execution if
131     a negative or zero wait time was passed as argument (since this is
132     a common indication of a bug either of the script or even of the
133     engine, which could lead to RT instability or even worse).
134 schoenebeck 2974 - ScriptVM: Implemented automatic suspension of RT safety
135     threatening scripts.
136 schoenebeck 3008 - Provide more user friendly error messages on syntax errors.
137 schoenebeck 3013 - Fixed NKSP parser warning "Not a statement" when assigning an
138     initializer list to an array variable.
139 schoenebeck 2871
140 schoenebeck 3050 * Instruments DB:
141     - Fixed memory access bug of general DB access code which lead to
142     undefined behavior.

155 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
156 persson 2197 - minor Makefile fix for building lscpparser when build and source

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

210     EngineChannel::InstrumentFileName(int index)
211     allowing to retrieve the whole list of files used for the loaded
212     instrument on an engine channel (a.k.a. part). Some GigaStudio
213     instruments for example are splitted over several files like
214     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
215 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
216     - Added new C++ API method Sampler::GetGlobalMaxStreams().
217     - Added new C++ API method Sampler::SetGlobalMaxVoices().
218     - Added new C++ API method Sampler::SetGlobalMaxStreams().
219 schoenebeck 2377 - Various "const" and "restrict" optimizations.
220 persson 2382 - all engines: add pan CC value to instrument pan parameter before
221     applying panning, instead of using two separate pan functions in
222     series (#182)
223 persson 2427 - added a lock guard class for exception safe mutex handling and
224     used it everywhere appropriate
225 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
226     - Exposed scale tuning to C++ API (along to the already existing standard
227     SysEx way).
228 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
229     and broken for ppc64. (Seq_cst loads and stores are actually not
230     used in LS, so the bug wasn't noticable.)
231     - lsatomic.h: added ARMv7 support
232 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
233     added various new C++ methods for this new feature / design change, old
234     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
235     as deprecated but are still there and should provide full behavior
236     backward compatibility).
237     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
238     unsafe and caused compilation error with clang 2.x).
239 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
240 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
241     sampler from the command line by providing LSCP aware features.
242 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
243     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
244     - VirtualMidiDevice: Added support for pitch bend.
245 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
246     polyphonic key pressure events (so far polyphonic pressure was not
247     supported at all, and channel pressure was rerouted as CC128 but not
248     used so far).
249 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
250     code is shared by all sampler engine implemementations, however only the
251     gig file format currently provides support for storing instrument scripts
252     (as LinuxSampler extension to the original GigaStudio 4 format).
253 iliev 2012
254 persson 2043 * Gigasampler format engine:
255     - implemented the "round robin keyboard" dimension
256     - fixed round robin and random dimensions for cases when number of
257     dimension zones is not a power of two
258     - made round robin use a counter for each region instead of each
259     key
260 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
261     - bugfix: filter keyboard tracking was broken
262     - filter performance fix (an unnecessary copy was made of the
263     filter parameters in each sub fragment)
264     - handle special case when pan parameter in gig file has max or
265     min value
266 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
267     doesn't sound naturally with a drumkit
268 persson 2408 - fixed EG1 modulation when attack or release is zero
269 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
270 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
271     conditions (see also previous commit on libgig).
272 persson 2673 - fixed behaviour of filter LFO
273 persson 2043
274 schoenebeck 2047 * SFZ format engine:
275 iliev 2012 - Initial implementation (not usable yet)
276 persson 2055 - added support for v2 multiple stage envelope generators
277     - added a fine-tuned v1 envelope generator instead of using the
278     one from the gig engine
279 persson 2058 - fixed memory leak and memory handling errors
280 persson 2061 - added support for trigger=first, trigger=legato and sw_previous
281 persson 2058 - allow non-numerical key values ("C#4" for example)
282     - "key" opcode now sets pitch_keycenter too
283     - fixed error when unloading instrument with same sample used by
284     multiple regions

294     - fixed crash when using sw_down/up
295     - improved logic for sw_lokey/hikey/up/down/last
296     - added more v1 aliases to parser
297 persson 2091 - reduced memory usage for sfz data

701 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
702     directory above)
703 persson 1899 - configure script fix: removed unconditional use of SSE
704 persson 1923 - fixed building with sqlite installed in a non-standard directory

706     - fix for new mingw-w64 version, which has usleep
707 schoenebeck 1639
708 schoenebeck 1601 * general changes:
709     - bugfix: on some POSIX systems instrument editor plugins refused to
710     load as we used a non-portable Linux specific struct field
711     (fixes bug #70, patch by Ronald Baljeu)
712 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
713     plugin DLL on Windows systems failed
714 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
715     - optimized the SynchronizedConfig class so it doesn't wait
716     unnecessarily long after an update
717 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
718     events (e.g. to highlight the pressed keys on the virtual keyboard
719     of gigedit)
720 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
721 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
722 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
723     is only used by very few systems, most pick the int math
724     implementation, which is usually faster)
725 persson 1748 - fixes for audio drivers with varying buffer sizes
726 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
727     VST plugin
728 iliev 1789 - notification events for stream/voice count statistics are now sent

732 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
733 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
734 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
735     be switched on by command line option "--stacktrace" (the automatic
736     stacktrace mechanism seems to be broken on most systems at the moment)
737 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
738     a pointer to the launched InstrumentEditor object
739 schoenebeck 1876 - added optional 3rd party user data parameter for following
740     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
741     InstrumentEditor::Launch(),
742     InstrumentManager::LaunchInstrumentEditor()
743 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
744     model more strictly
745 persson 1895 - fixes for using large audio device buffers
746 persson 1951 - Windows: add the installation directory to the DLL search path

748     gigedit on systems with other GTK versions installed)
749 schoenebeck 2509 - updated linuxsampler man page
750 schoenebeck 1601
751 schoenebeck 1599 * audio driver:
752     - removed the nonsense audio channel constraint (which was hard coded to
753     max. 100 audio channels) for most audio drivers
754 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
755     opposed to the LSCP specs
756 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
757     reflected the wrong value
758 persson 1644 - fixed a memory management bug in ASIO driver
759 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
760 persson 1777 - JACK: use jack_client_open instead of the deprecated
761 persson 1748 jack_client_new
762 iliev 1829 - added (experimental) CoreAudio driver
763 persson 1888 - applied old fixes to the ASIO driver that were included in the
764     previous binary release but accidentally never committed to CVS
765     (fixes #117)
766 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
767     win64)
768 persson 1895 - VST: added support for sample rate and buffer size changes
769     - VST: close editor (Fantasia) when the VST is removed

774     stereo
775 persson 1922 - added channel routing, fxsends and midi maps to the settings
776     stored in the plugin state
777 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
778     AudioChannel::CopyTo() methods using GCC vector exensions
779     (if available)
780 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
781     exception when getting parameters from a disconnected device
782 schoenebeck 1599
783 persson 1651 * MIDI driver:
784     - added JACK MIDI driver
785 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
786     want to (mis)use it for some purpose ("fixed" in all current MIDI
787     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
788 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
789 persson 1887 CoreMidi or AU
790 persson 1889 - fixed mingw-w64 compilation error in MME driver
791 persson 1924 - made program change handling in MIDI thread real-time safe by
792     moving the logic to a non-RT thread
793 persson 1951 - fixed minor memory leak in ALSA driver
794 persson 1651
795 schoenebeck 1604 * instruments database:
796 iliev 1603 - avoid time consuming samples scanning when adding instruments
797     to the instruments database
798 iliev 1727 - added support for handling lost files in the instruments database
799 iliev 1781 - Implemented option for adding instruments in separate directories
800     in the instruments database
801     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
802 persson 1908 - work-around for missing fnmatch function on Windows to make
803     instrument database compilable
804 schoenebeck 1930 - added instrument database support on Windows
805     works with both standalone mode and VST plugin.
806     the instruments DB file is located in
807     %USERPROFILE%\.linuxsampler\instruments.db which allows different
808     databases for each windows user
809     if no DB is present it automatically creates the .linuxsampler subdir
810     and then creates an empty DB
811 persson 1943 - fixed recursive import, which was broken on Windows
812 iliev 1603
813 persson 1644 * Gigasampler format engine:
814     - fixed a memory leak that could happen when a channel was deleted
815     while notes were playing
816 persson 1646 - made it possible to load an instrument even if the audio thread
817     isn't running
818 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
819     enough for piano gigs with pedal noise samples
820 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
821     respective FX send MIDI controller was used
822 schoenebeck 1724 - added support for GM global device volume SysEx message
823 schoenebeck 1762 (can be selected at compile time to either apply globally to the
824     whole sampler [default] or only to the sampler channels that are
825     connected to the respective MIDI input port the SysEx message arrived
826     on)
827 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
828     sometimes wrongly killed in the same buffer, causing no sound to
829     be played
830 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
831     which is usally used to switch a part between chromatic sounds and
832     drumkit sounds (as opposed to their common default setting of MIDI
833     part 10 being a drumkit part and all other ones chromatic parts), in
834     LS however one can switch between the first 16 MIDI instrument maps
835     defined for the sampler
836 persson 1764 - made it possible to create multiple sample channels even if the
837     audio thread isn't running
838 persson 1844 - fixed crash when removing channel with active voices (#116)
839 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
840     un-cache the respective sample if it's really not used by any
841     sampler engine anymore
842     - re-cache samples in case they were changed by an instrument editor,
843     e.g. when a sample was added while playing (#82)
844 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
845     same time stamp as the voice's note-on event and occured both in the
846     same audio fragment cycle (fixes bug #112)
847 persson 1858 - added support for the "fine tune" and "pitch bend range"
848     instrument-level gig parameters
849     - fixed minor artifacts in pitch bend handling
850 schoenebeck 1860 - added support for GS Reset SysEx message
851 persson 1862 - allow gig files to use unlimited downward pitch shifting
852     - added a limit check for upward pitch shifting
853 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
854     note was silent
855 persson 1923 - fixed crash happening when a pitch bend event arrived at the
856     same time a new instrument was loading
857 persson 1644
858 schoenebeck 1687 * LSCP server:
859     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
860     react on MIDI data arriving on certain sampler channels (so far only
861     Note-On and Note-Off events are sent via this LSCP event)
862 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
863     react on MIDI data arriving on certain MIDI input devices (so far only
864     Note-On and Note-Off events are sent via this LSCP event)
865 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
866     SET DB_INSTRUMENT FILE_PATH
867 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
868     frontends to send MIDI messages to specific sampler channel
869     - added two additional fields to GET FILE INSTRUMENT INFO command -
870     KEY_BINDINGS and KEYSWITCH_BINDINGS
871 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
872     was incorrect
873 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
874 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
875     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
876     be triggered respectively
877     - added new LSCP command "SET STREAMS" to globally alter the maximum
878     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
879     which will be triggered respectively
880 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
881     a gigedit file dialog is opened)
882 iliev 1848 - close all connections when LSCPServer is deleted
883 iliev 1882 - hard close of all sockets on exit
884 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
885     driver
886 schoenebeck 1687
887 iliev 1761 * Bug fixes:
888     - fixed a crash which occurs when removing a sampler channel waiting
889     to start instrument loading after another channel
890 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
891     instrument loading in progress (bug #113)
892 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
893     instrument with PERSISTENT load mode
894 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
895     - fixed memory leaks when issuing the following LSCP commands:
896     GET AUDIO_OUTPUT_DRIVER INFO
897     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
898     GET MIDI_INPUT_DRIVER INFO
899     GET MIDI_INPUT_DRIVER_PARAMETER INFO
900     - fixed possible compilation error when sqlite is not present
901 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
902 iliev 1847 - fixed crash when changing the audio output device of a sampler
903     channel with loaded instrument and start playing notes
904 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
905 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
906     PowerPC, which probably could cause crashes on that platform
907 persson 1889 - fixed a memory management error which could cause a crash when a
908     plugin was unloaded
909 persson 1896 - bugfix: two private structs had the same name, which could cause
910     problems if the linker chose the wrong constructor
911 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
912     Windows
913 iliev 1761
914    
915 schoenebeck 1560 Version 0.5.1 (6 December 2007)
916 schoenebeck 1454
917     * packaging changes:
918     - added autoconf checks for pthread library
919     - added autoconf check for pthread bug found on certain NPTL-enabled
920     glibc versions (see Gentoo bug report #194076)
921 senoner 1502 - added autoconf checks for MS Windows
922 schoenebeck 1454
923 persson 1455 * general changes:
924     - bugfix: the thread used by an editor plugin didn't die when the
925     editor closed
926 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
927     out all the space. operator--() did not apply size_mask after
928     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
929     order to avoid problems with the _NonVolatileReader functions.
930     - bugfix: Stream.h: added a missing divide by BytesPerSample in
931     GetWriteSpace(). Since this function is currently only used in
932     the stream's qsort() compare function, it didn't trigger any
933     bugs.
934     - Resampler.h, Synthesizer.h: cubic interpolation now works in
935     24bit mode too. Faster method to read 24bit words on little
936     endian machines (x86): replaced 3 byte reads + shifts with a 1
937     unaligned 32bit read and shift
938     - experimental support for MS Windows (MIDI input via MME, AUDIO
939     output via ASIO)
940     - made handling of SIGINT signal (Ctrl-C) a bit more robust
941 iliev 1541 - support for monitoring the total number of active disk streams
942     (new LSCP commands: GET TOTAL_STREAM_COUNT,
943     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
944 persson 1455
945 senoner 1500 * AUDIO driver:
946 persson 1534 - added Windows ASIO low latency audio driver
947 senoner 1500
948 senoner 1485 * MIDI driver:
949 schoenebeck 1495 - added MME Windows MIDI driver
950 senoner 1485
951 schoenebeck 1471 * LSCP server:
952     - added support for Windows style path / filenames, however with
953     forward slash path separators instead of backslash
954     (i.e. "C:/foo/bar.gig")
955 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
956     apostrophes as well
957 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
958     "LIST FILE INSTRUMENTS <file>" and
959     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
960     about an arbitrary instrument file on the system where the sampler is
961     running on
962 schoenebeck 1471
963 schoenebeck 1424 Version 0.5.0 (15 October 2007)
964 schoenebeck 947
965 schoenebeck 1065 * packaging changes:
966 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
967     API header files anymore
968 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
969     the Doxygen API documentation (explicitly listed in Doxyfile.in)
970 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
971     capable to execute our autoconf environment, thus no need anymore
972     to maintain the compile time configuration file (osx/version.h) for
973     OSX manually (patch by Toshi Nagata)
974 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
975     parameters
976 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
977     C++ API header files, all implementation internal global definitions
978     are now in global_private.h
979     - atomic.h is not exposed to the C++ API anymore
980     - no need to include config.h anymore for using LS's API header files
981     - fixed warnings in API doc generation
982 schoenebeck 1065
983 schoenebeck 947 * general changes:
984     - replaced the old, confusing MIDI program change mechanism by a
985     flexible MIDI instrument mapper which allows to map arbitrary
986 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
987 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
988     loaded on the respective channel when such MIDI program change
989     messages arrive, beside that, each entry allows to define a life-time
990     strategy for the instrument, so the user can define whether the
991     instrument should i.e. be permanently loaded (to be able to switch
992     quickly among sounds) or i.e. loaded just on demand when the
993     respective program change arrives (to safe RAM space), as well as a
994     global volume factor for each entry, so the user can adjust the volume
995     dynamic of his mapped instrument collection without having to modify
996 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
997     MIDI instrument maps and assign each sampler channel individually
998     a certain map, so that i.e. separation of normal instruments and
999     drumkits is possible
1000 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
1001     MIDI instrument maps, MIDI instruments, FX sends, global volume.
1002 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
1003     due to a constant size RingBuffer FIFO which is now replaced by a
1004     dynamic (unlimited) size std::list FIFO
1005 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
1006     output channels for being processed by external effect processors
1007     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1008     controllers
1009 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
1010 iliev 1130 - Implemented new, improved notification system
1011 schoenebeck 1149 - fixed compilation errors regarding OSX
1012     (patch by Toshi Nagata)
1013 iliev 1161 - implemented instruments database
1014 iliev 1345 - added support for escape sequences to the instruments database
1015 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
1016     within the sampler's process (by using instrument editor plugins),
1017     you'll notice the new "Registered instrument editors:" message on
1018 schoenebeck 1407 startup, added a new LSCP command:
1019     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1020 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
1021     given sampler channel, the plugin path can be overridden at compile
1022     time with ./configure --enable-plugin-dir=/some/dir
1023 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
1024     in the sampler's process to safely edit instruments while playing
1025     without a crash (hopefully) by either suspending single regions
1026     wherever possible or if unavoidable whole engine(s)
1027 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
1028     policy and priority on thread level, set a minimum stack size for
1029     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1030     threads simply inherited properties of starting thread instead of
1031     setting their own policy and priority
1032 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
1033     main process did not wait for the stack trace process to finish
1034     its output
1035 persson 1248 - fixed some minor memory leaks
1036 schoenebeck 1259 - reenabled assembly features support, at the moment only for
1037     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1038 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
1039     register, to avoid relocations in the text segment at runtime)
1040 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
1041 schoenebeck 947
1042     * MIDI driver:
1043     - dispatch bank select (MSB and LSB) messages
1044    
1045 schoenebeck 1049 * audio driver:
1046     - the ALSA audio output driver parameters now reflect the correct
1047     parameter value ranges for the respective selected sound card
1048     (patch by Till Wimmer, a bit fixed and extended)
1049    
1050 persson 951 * Gigasampler format engine:
1051     - if a filter is used and EG2 finishes before EG1, let the voice
1052     die when EG2 has finished (this fixes a problem with clicks and
1053     voice starvation for some gigs)
1054 persson 1038 - playback is no longer disabled during instrument loading
1055     - all notes playing on a channel that changes its instrument keep
1056     playing with the old instrument until they get a note off
1057     command
1058 persson 1039 - EG fix: a release value of zero could cause noises or crash
1059 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1060 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
1061     above max sustain level, which means that there is a decay phase
1062     even if sustain is 100%
1063 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
1064     noises or crashes
1065 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
1066 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
1067     supplied to the configure script (fixes #46)
1068 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1069     instead of a fix value
1070 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1071     127 (solo mode) only kill voices if the respective mode really
1072     changed
1073 persson 951
1074 schoenebeck 1244 * LSCP server:
1075     - fixed compile time error for old Bison versions
1076     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1077 schoenebeck 1245 - parser now supports extended ASCII character set
1078     (up to ASCII code 255, i.e. includes now umlauts and accents)
1079     - filename arguments in LSCP commands now allow to use escape
1080     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1081     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1082     code value like \xf2) (fixes bug #24)
1083 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1084     least one of their text-based parameters (i.e. name, description):
1085     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1086     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1087     "SET DB_INSTRUMENT_DIRECTORY NAME",
1088     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1089     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1090     "FIND DB_INSTRUMENT_DIRECTORIES"
1091 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1092     occured, the unexpected character and the actually expected, possible
1093     character(s), the latter only if less than 5 possibilities)
1094 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1095     settings
1096 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1097     of strings were treated as being one string containing commas
1098     (fixes #57)
1099 schoenebeck 1244
1100 iliev 959 * Bug fixes:
1101     - fixed crash occurring on certain LSCP scripts (Bug 39)
1102 persson 1038 - another thread safety fix for lscp "load engine" and "set
1103     channel audio output device"
1104 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1105     on a sampler channel with connected MIDI device
1106 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1107     device connected to a sampler channel to number less then or equal
1108     to the index of the port to which the sampler channel is connected.
1109 iliev 1296 - The previous bindings were not been disconnected when altering
1110     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1111     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1112 iliev 1297 - The active stream/voice count statistic was incorrect.
1113 iliev 1298 - notification events were not been sent for some sampler
1114     channel changes
1115 iliev 1305 - added default min and max values to restrict the number of allowed
1116     audio output channels and MIDI input ports
1117 iliev 1306 - the connection to the PCM interface is now closed when destroying
1118     an audio output device
1119 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1120 iliev 959
1121 schoenebeck 1221 * test cases:
1122     - updated and fixed (haven't been touched in a while)
1123    
1124 schoenebeck 937 Version 0.4.0 (24 November 2006)
1125 persson 696
1126 schoenebeck 697 * packaging changes:
1127 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1128     to post-(un)install steps; added devel package for liblinuxsampler;
1129     to linuxsampler.spec (RPM)
1130 schoenebeck 697 - install necessary development header files for allowing 3rd party
1131     applications to link against liblinuxsampler
1132     - liblinuxsampler's API documentation can be generated with 'make docs'
1133     (Doxygen required)
1134 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1135     implementation (currently either an integer math solution or a
1136     di-harmonic approximation), automatic detection can be overriden
1137     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1138     configure script argument though (mandatory for cross-compilation)
1139 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1140     provided some on his own (as CXXFLAGS)
1141 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1142     messages
1143 schoenebeck 852 - added compile time options to allow disabling the various audio and
1144     MIDI drivers
1145 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1146     (patch by Ebrahim Mayat)
1147 schoenebeck 697
1148 persson 696 * Gigasampler format engine:
1149 schoenebeck 738 - extensive synthesis optimization
1150     (reimplementation of EGs and LFO(s), removed synthesis parameter
1151     prerendering and the synthesis parameter matrix in general, splitting
1152     each audio fragment into subfragments now where each subfragment uses
1153 persson 830 constant pitch and filter coefficients. The volume coefficient is
1154     linearly interpolated inside a subfragment, unless
1155     --disable-interpolate-volume is set.)
1156 persson 696 - fine tuning of the EG modulation parameters
1157 persson 729 - improved filter cutoff calculation by adding support for the
1158     following gig parameters: Cutoff freq (used when no cutoff
1159     controller is defined), Control invert, Minimum cutoff, Velocity
1160 persson 791 curve and Velocity range. The keyboard tracking now scales
1161     cutoff frequency instead of resonance.
1162 persson 877 - added support for gig parameter Resonance.
1163 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1164 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1165     which can be overridden with --enable-global-attenuation
1166 persson 783 - EG fixes: made the length of "attack hold" stage more
1167     accurate. Release stage can now start before attack stage
1168 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1169     time now has a minimal value to prevent clicks.
1170 persson 799 - fixed pitch changes larger than one octave
1171 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1172     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1173     all modes can be altered via standard GM messages, that is CC5 for
1174     altering portamento time, CC65 for enabling / disabling portamento
1175     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1176 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1177     parameter) and crossfade
1178 persson 831 - added support for the "attenuation controller threshold" gig
1179     parameter
1180 persson 832 - added smoothing of volume changes caused by control change
1181     messages
1182 persson 865 - sample loop parameters are now taken from the DimensionRegion
1183     instead of the wave chunk
1184     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1185     not equal to a power of two
1186 persson 877 - reimplementation of the filter algorithm. The new filter is more
1187     accurate and supports all gig filter types, including bandreject
1188     and lowpass turbo.
1189 persson 903 - real support for 24 bit samples - samples are not truncated to
1190     16 bits anymore
1191     - support for aftertouch (channel pressure, not polyphonic
1192     aftertouch)
1193 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1194     amplifying from 0)
1195 persson 696
1196 schoenebeck 711 * LSCP server:
1197     - fixed application exit on broken pipe error (fixes bug #20)
1198 iliev 793 - fixed the notification messages delay due to lack of
1199     network activity (fixes bug #26)
1200 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1201     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1202 schoenebeck 711
1203 schoenebeck 838 * audio driver:
1204     - added aRts audio output driver (by no means RT safe)
1205    
1206 schoenebeck 775 * MIDI driver:
1207     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1208     messages several times instead of once
1209 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1210     for events (i.e. for offline rendering based MIDI drivers)
1211 persson 922 - added checks for bad MIDI data
1212 schoenebeck 775
1213 schoenebeck 900 * linuxsampler application:
1214     - show available sampler engine types on startup
1215    
1216 schoenebeck 705 * general changes:
1217     - support for muting sampler channels and solo mode of the same, two new
1218     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1219     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1220     introduced for this, the behavior is the same like on a mixer console
1221 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1222     --enable-process-muted-channels which can be used to enable the
1223     processing of muted channels.
1224 iliev 777 - support for sostenuto pedal
1225 iliev 779 - support for monitoring the total number of active voices
1226 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1227     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1228 persson 835 - fixed some memory management errors
1229 persson 841 - fixed some concurrency problems that could lead to crashes when
1230     LSCP commands were executed
1231 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1232     sampler channel (fixes bug #36)
1233 schoenebeck 705
1234 schoenebeck 692 Version 0.3.3 (15 July 2005)
1235 schoenebeck 686
1236     * packaging changes:
1237     - fixed compilation with gcc 4.0
1238    
1239 schoenebeck 687 * Gigasampler format engine:
1240     - LFO preprocessing was performed even though the respective LFO was
1241     disabled by the instrument patch (minor efficiency fix)
1242 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1243     for volume ramp downs in the same fragment (needed for current voice
1244     stealing implementation) then simply inform the user with a warning
1245     about possible click sounds and reduce the volume ramp down
1246     appropriately instead of cancelling the audio device connection
1247 schoenebeck 687
1248 schoenebeck 677 Version 0.3.2 (24 June 2005)
1249 schoenebeck 609
1250     * packaging changes:
1251     - updated autotools build files to compile on OS X
1252     (conditional compilation of CoreMIDI and MidiShare drivers)
1253 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1254     './configure --disable-asm' (definitely not recommended)
1255 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1256     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1257     (due to 'dist-bzip2' automake option)
1258 schoenebeck 649
1259     * Gigasampler format engine:
1260     - support for the gig parameters for "release velocity response" curves
1261     - fine tuning of the EGADSR envelope
1262     - volume of release triggered samples now depends on note-on velocity,
1263     note length and gig parameter "release trigger decay" instead of
1264     note-off velocity.
1265 schoenebeck 663 - revised voice stealing
1266     (fixes crash and endless loop caused by voice stealing)
1267 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1268 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1269     instead of when the respective voice is actually launched
1270     (fixes undefined behavior if stolen voices belonged to a key group -
1271     this case was followed by a "killed voice survived" error message)
1272 schoenebeck 669 - fixed minor issue with null/silence samples
1273     (those stole voices even though they don't need a voice at all which
1274     resulted in "voice stealing didn't work out" messages)
1275 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1276     instrument or audio output device change
1277 schoenebeck 654
1278 schoenebeck 620 * LSCP server:
1279 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1280 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1281 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1282 schoenebeck 609
1283 schoenebeck 668 * linuxsampler application:
1284     - added command line parameters --lscp-addr and --lscp-port to override
1285     default IP address and port of LSCP server
1286    
1287 schoenebeck 579 Version 0.3.1 (24 May 2005)
1288    
1289     * initial release
