There doesn’t seem to be an option to make the PAFL Bus route to the main outs – or in my case monitor outs. It would be ideal to solo stuff using my monitors and not my headphones.
Oh yes there is. So simply by routing PAFL L&R (under I/O / Outputs / Monitor Out) to a few spare LOCAL outputs (in my case on my SQ7 the last ones 15 & 16) and plugging your speakers in to them your PAFL button becomes a solo button. Easy. Well after two hours it’s easy!
