I had a Casio DG-20 guitar controller I purchased new for $99 in the early nineties. It had a built-in FM synth sound module tempo rhythm machine and four drum pads. Mario mentioned each string occupied a midi channel. This had a switch that merged the six channels into one channel.

A few years ago HBO had a series about a fictional band. One of the band members played a Casio DG-20. Interest in the instrument soared. I was offered $400 and accepted the offer.
