For a Krell patch I'm going to need to figure out how attenuators / attenuverters (or whatever else does the job) contains the pitch signal to within maybe a 2 or 3 octave range. Right now it's got way too many high and low pitch squeals and growls, and a bandpass filter isn't the way to fix it. I want it to proportionally fit the whole output within a specific range, not just cut off the top and bottom.
