Yeah, well, if said pins actually controlled the volume for the first and
second oscillators, each voice would be sharing the same VCA. I honestly
don't see how that would work very well... one filter, after the VCA's, one
per oscillator, is how I always thought the Poly was laid out. I could be
wrong, however.

I would expect these two pins to control the master Level for the oscillators,
that is, parameters 17 and 27. But I could be wrong.
