I do not know either, and was asking in the context of the MIDI discussion. I 
have always assumed that XG was an extension to the standard MIDI 
specification. And again I always assumed that an interpretative function 
existed somewhere in software layers either within a driver or in a filter. 
As with your Yamaha PSR-740 XG are all functions / prsets & ?? interpreted by 
the Linux MIDI? I am only guessing how all of this works.
