That is definately my understanding. I assumed also that this is why you
have 4x4 and higher midi interfaces for computers. Since your computer is
fast enough to handle more than 31.25kbs, then making parallel synced
interfaces would be a very easy solution. For my setup I have my computer
drive my Korg Triton, Boss Dr770 Drum machine and control my 2101, all
through midi. In this situation, I never have enough data on the line at
a time to cause problems. But, if I ever wanted to do live performance I
would have to use at least 4 or 5 triton modules since I use so many
sounds at a time. I do have to be careful with the controllers, and that
is another issue. That I think is why I don't understand why midi would
need to be replaced or enhanced, but, this is my limited knowledge.
I also use a midi patchbay to do all the routing and/or merging
digitally. So I use midi as one would network computers with a hub
instead of chained, like thin ethernet.
This make any sense? :)
