Effects triggered by Audio (Help)

Sonic Sea's icon

I'm working on a simple, controllable way to add effects triggered by sound - Patch is pasted below

Couple of things:
Is there a way to make the slider/gain control the input better?
Can I set the Vizzie effects to 0 in order that clean video goes through even when they are switched on?

I feel as though I'm not doing this in a very elegant t way :(
