If you're doing digital (you did say MIDI) I'm not sure what you could
do with multiple contacts that you couldn't do with one, except maybe
some redundancy for a high-availability keyboard, with failover to the
second keyboard in extreme situations like having an elephant step on
the first one :-)

FWIW, even the duophonic Odyssey's 2- and 3-bus keyboards used only
one bus for CV.
