So Rich, you got the nerve to call "Christmas gift" a humble waveform generator without, at least, an electronic switch..?? :icon_mrgreen:

Is IC3A correct?

Otherwise looks super neat! Plus, it would only take a few parts to switch b/w envelope filter and tremolo, too.

Well spotted, Bean. I looked at that too but only saw what I expected to see!

One other question: what's with the two depth controls?
