Title: FxMixer: turn off effects

Ok, I think this works, it at least seems to, but I'm still very unsure if I truly get how the FxMixer is meant to work so please review carefully and see if anything looks questionable...

The purpose of this is to restore the functionality of decay knobs and skip the processing of effects when there's no input, closes #646
