So how about “customize-able vocal chain” then? Like TDR’s Limiter No6, only it could be for vocals. Kind of like a Vocal Channel strip. You’ve already got most of the pieces, you could strip down the UIs and put 'em in a configurable container. That covers 1 and 2, forget about 3. Who wants another “signature plugin” anyway? Just Boz is good enough!
Ha! I’m getting ahead of myself, but you could do a BEFORE-AFTER promo video. You could sing the before part, then have Cristina or someone sing the after. (Disclaimer: I have no idea if you can sing or not. No offense intended!)
