So, I noticed that the sawtooth sounded really raw and I did some detective work and I noticed that my idea that an actual sawtooth wave was happening midway between the triangle and sawtooth markers on the knob. Not a huge deal, but is this by design or should I do some sort of calibration or something?

On a scope or by ear?

The sharktooth waveforms usually lies about where you are talking. If by ear, I would guess that's what you are hearing.

Sharktooth? I'd never even heard of such an animal. Shark fin... it does look like that.

as opposed to my ATC-1's sawtooth... (which is what I'm used to)

I didn't grab a pict of it when it was at the exact "sawtooth" part of the indicator, but it didn't look much like a sawtooth at all. (all of these are with the filter wide open) I got curious when I was listening to the raw oscs and it wasn't what I was expecting. I actually really think that part of the Phatty's dial is a "sweet" spot. At least in terms of what I think of as "phatness."

The shark tooth is a tri-saw hybrid as found on the minimoog model D.
