Not sure about the correct terminology (no native speaker here - but even in German I wouldn't know the right term, ha!), but I'd like to be able to use an option for "slow-down endings".

Almost never I use simple fade-outs (booooring!); almost always I create a real ending for a song (as you would for a movie, a book etc.!), and in some cases, it just would be nice to slow that ending down; in fact, quite often I feel some kind of urge to do exactly that - you know, like a band on stage would ...?

I hope at least someone understands what I'm talking about and can maybe lend some support. ^^
