dual mix rack issues v1.8

Ok so we are running an R72 and two idr16s. all on v1.8.

basicall i cannot PFL anything plugged into the second rack.

also if i route a channel to a group rather than main mix, you can see the signal at the group but it does not get to the main LR bus.

everything from the main idr works fine!

anyone got any insite to this?

is there something obvious we should be doing to make pfl work in dual mix rack mode?

I had this problem when first trying dual rack, however I was using Ethersound and not ACE which I have no experience of and it was due to an Ethersound routing problem which I believe was sorted out in a maintainence release of V1.7

Suggest you give Technical a call and just check
