I mapped my MIDI Fighter Twister to a bunch of the operator parameters and turned on the arpeggiator. Instant techno.
On another instance, made the matrix you see above, put it on 3 voices 50% detune mono w/ portamento, instant lead.
Very glad I don't have to program these with a DX7's interface.
I don't know anything about music production but I'm very horny for arcade buttons. Cool gear.
