Hmmm it's very odd, if I set up a path with just my GK send and no Aird preamp in the active signal chain the cab sim turns off for both main and sub out.
So even if I put a divider with set to single and the A path but have an AIRD preamp on the inactive B route it's disabled.
Worth noting that this is when using the GT1K as an interface, haven't tested using with an actual amp because the child was asleep. Not sure if it's a bug or intentional thing due to the way AIRD processes the relationship between stages in the chain but it's annoying to have to sacrifice a divider just to us an ir.
