I don't know?

Good point!

As I already pointed out, I never noticed zipper noise when sending
volume control to a synth, but sometimes 128 steps (and IIRC all 128
steps were used) were not enough. Perhaps it was neither linear nor log,
but bad programmed usage of those steps. I remember that for panning
often less then 10 steps were provided, I dislike/d this a lot. IIRC
panning sometimes didn't effect a hold note, it was used for the next
played note, so at least this can't be compared to a digital mixer.
