No experience with this exact tool, but I use Reason which is a DAW with a Skeumorphic UI (right down to connecting components with virtual wires) and I find knob-fiddling to work just fine for me. The knobs read from my mouse scroll wheel when I hover the cursor over them. And in some (most?) cases, there's also a value field I can edit directly if I want to be precise.

Or if I want to automate a gradual knob change over time as the song plays, I can either record myself "scrolling" the knob or draw the change into an automation track (and again, can set precise values for knob values at precise times if I want to).

But of course, professionals own hardware that they connect to the DAW, which renders most of that stuff irrelevant.
