Modular Synth Panels

Will just pointed out that if we use 100K lin pots for such a gadget,
we could have a switch to send the signal through a couple op-amps
with resistors to make the pot act like a log pot... so we could
switch each pot between lin (truly passive) and log (via op amps and
resistors set to unity gain).  He's thinking Tellun MUUB4.  Kind of a
cool idea.  I'll ask him to explore the little circuit design.  So
this would be an added benefit of building it into a 1U panel... that
it could have this active component just for fun.  Bill and Will
