I am curious - has there been any move to modernize the MIDI

There has been - there is a midi over usb standard.
Midi is a poor starting point for modernisation not just beacause of
the pragmatic compromises mentioned above but also because it is
wholly unlayered (the spec covers everything from the physical up to
the presentational layer),
That could be separated fairly easily, I'd think.
and has it's expansion room squeezed into
the SysEx ghetto.
That's a big problem.
Midi over ethernet would be even less pleasant, and
less logical, than doing RS-232 over ethernet.
Only reason I mentioned Ethernet is that there are analog musical
instruments around already that can transmit their audio via Ethernet
(instead of analog audio cables).
OSC has fixed these problems and should have been built into
everything since the mid-90s but so many people have invested time in
learning MIDI that they wouldn't countenance working with anything
else. It looks like RESTful web services may eventually replace both,
however.
I suspect that MIDI won't be budged. It is a standard in the music
world, and I doubt that many musicians care about it's limitations. They
may not even be aware of them. MIDI certainly keeps time in a lot finer
increments than I'm able to play - that's why sequencer programs have
quantization functions!
How does the " XG " extension play into this? How proprietary is it?
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.
I've no clue. I have a Yamaha PSR-740 configuration file I use with
Rosegarden that lists all the extended XG voices. I don't know if it has
any support for presets or the pile of other things the keyboard has. I
haven't tried driving the PSR-740 from Rosegarden, since I don't yet
have MIDI set up.
