[PD] this is crazy

I noticed something similar on 0.40 (pure:dyne)

Something to do with DACs. I had a patch where the [dac~]
I was adding or deleteing didn't have any correspondence to
the signal it was (supposed to be) outputting.

Drives me insane, so I avoid that version now.

And it's intermittent/random/sensitive to initial conditions.
Sometimes a patch gets the problem, sometimes not.
