> How can I rout the LR output & PAFL outputs to ALT output
Maybe I’m misunderstanding it, but you can’t route L/R and PAFL on your A/B output sockets at the same time.
But maybe alternatively to nottooloud’s suggestion:
You could route Listen L/R to A/B and assign it a soft rotary of your SQ-6.
Then you have PAFL adjustable on your A/B.
And if no PAFL is selected (or PAFL of L/R is selected), then you have L/R to your A/B – also adjustable.
