That's a nice modification, Scott. While it can perform a similar
function to Larry's proposed module, Larry's concept is different. It
provides two independent CV processors, each with a reversible
attenuator and a bias pot. The modified Multimix allows summing a bias
to the MIX3/OUT, in addition to providing up to three simple bias
outputs. I can see having both types of module.
