Pat, I showed you one when you were at my place. It's the Roland GI-10, and it serves a dual function: Converting a single-note analog input to a single-note MIDI out, and converting hex (up to six note) input from a GK-equipped device to up to six notes of MIDI out. It's a legacy device, over 20 years old, but I have bought two through eBay. (Don't ask—one was stolen.) The more recent GI-20, while reputed to have better tracking, lacks the quarter-inch analog input of the -10.
