Wish update numbers on fx-edit knobs when they're attached to controllers

[flying_walrus]

while dialing in tones, it's convenient to connect controllers (e.g. pedal 1) to the parameters of an effect and then alter them while playing, but there's no way to see what the actual value you've set.

it would be cpu intensive to do this while the value is changing, but maybe after you haven't moved the pedal for 500, the numerical display could update?
