c64-2-synth hack

[Curtin, Steven D (Steven)]

Just to give credit where credit is due-

Bob Yannes, The designer of the SID, went on to bigger and better things,
namely the DOC chip that was the heart of the Ensoniq Mirage and ESQ-1  (Son
of SID? :) ).  He's one of the founders and a vice-president at Ensoniq, and
was one of many people at Ensoniq who are into analog and vintage synths.
