Sysex files / Preset Text files
SysEx Files .SYX are files with one or more MIDI system exclusive messages in
binary code.
The Drehbank
needs to have one separate SysEx message per control knob, so
that a complete Drehbank SysEx File is built from 128 single SysEx messages (2
banks with 64 control knobs per bank).
Remember
SysEx stands for "System Exclusive Message". SysEx is a Midi event
that has only one norm. This norm begins with byte F0 (Start of System
Exclusive Statusbyte) and ends with byte F7 (End of System Exclusive
Statusbyte).
All bytes between F0 and F7 are freely definable. The format for SysEx
implementation is usually to be found in the manual of the equipment you
are using with the Drehbank.
Generating SysEx files
Select "Make Sysexfile" from the
"Preset" menu and a dialogue window
opens. Here you can select the knob you
want to integrate into the SysEx file.
Click on O.K. to open the data browser
so as to name and save the file. Make
sure that at the end of the file name you
type .SYX
You can send these SysEx files from a
sequencer or a SysEx dumper to the
Drehbank.
Warning
When dumping Sysex data from a sequencer or SysEx dumper to the
Drehbank make sure that between the SysEx information of each control
knob there is a gap of at least ten (or more) milliseconds. If the gap is not
long enough then it is possible that you could overload the Midi buffer.
An Midi buffer overload is indicated by the constant glowing of the L.E.D.
