Polivoks Sawtooth Wave

So, I remembered I do have an oscilloscope...of sorts. I have Audiofile Engineering's Spectre, which does have an oscilloscope, but it's limited to what your audio interface can do, and unfortunately my 828mkII is not DC-coupled, so I can only use the software scope for audio rate stuff.

So anyway, that works perfectly for checking out what the waveform looks like when having the Harvestman Polivoks self-oscillate and have it's BP output FM itself.

I mentioned in the Polivoks review that it has a "saw-like sounding hybrid" when doing this...well I wasn't quite IS a sawtooth!

It's a little quiet (amplitude-wise) than say, the Plan B Model 15, but it's a very cool and usable sawtooth wave. I had a lot of fun gating it with the Model 13 Dual Timbral Gate and even layering it with the Model 15, tuning it to harmonic intervals.

This is my first state-variable filter which has simultaneous LP/BP/etc outputs so I'm curious if other filters have a similar response when patched in such a fashion. Sound off in the comments if you know.
