You have a great point Cary! But I wonder if a compromise could be made such
that a mixer designed for DC (or more precisely CV and modulation) would
handle audio with some minor distortions (since I'd think a slow slew would
more round an audio square or saw wave, and I typically use sines or
triangles for audio modulation due to reduced sidebands). This would be
reasonable tradeoff. An audio (AC) mixer should be maximized for audio
obviously.
