[sdiy] Moogey jitter

Yes. Certainly not what I'd expect from a "warm" (whatever this is)
VCO. I don't think the Korg Mono/Poly (SSM2033-based VCOs)
sounds like this.

BTW, I'm also using SSM2033s in my Minimoog Clone.
I had *no* idea about what a Mini should be like, back then.
(This was built before synth-diy started, I think)
But I tend to like its sound. (The 2033 was a lucky choice.)
I remember there were issues with decoupling the heater
part of the chip, to prevent HF oscillations.
