[sdiy] Moog filter self-FM questions

[cheater cheater]

I was looking through Tim's papers earlier. The animations were indeed
very interesting and educative, I hope he makes more.

I am afraid the complete Moog Filter paper from Tim is more than I can
dedicate myself to this month.

So guys, looking back at the original question..
to what extent does the audio *really* modulate the cutoff?

Cheers
