I don't know - and each week I play a Yahama PSR-740 keyboard with
Yamaha's XG. I've recorded some MIDIs using it, and they open just
fine
in Rosegarden and play in fluidsynth. Or maybe
you're talking about
something else?
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.
