[sdiy] linearize OTA for VCF?

[Ian Fritz]

Hi Jim --

Thanks for the reminder -- I need to have another look at your circuits.

I was just thinking that since so many people seem to believe that the
distortion in the Moog ladder sounds good, why doesn't anyone talk about
distortion in OTA-based designs?

Have you listened for sonic differences (other than noise level) in the
linearized vs. non-linearized cases?

  Ian
