+1 on that. The advantage of differently sized and arranged icons is
the recognizability of the state it is set to. With icons of faders
it will use a lot more screen real estate when trying to convey a
topological structure though.

I guess the question between icons resembling either pots or faders
doesn't fully cut to the essence.

While I might prefer knobs for an envelope to use in a live context,
I concur that the faders in the additive synth totally make sense
and would be ridiculous with knobs.
