Re: [motm] Panning VCAs - a different approach

2004-09-13 by Richard Brewster

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.
