Hi again, many thanks, but...
unfortunately, my quantum is still not allowing any external OUTS, except MAIN OUTS. Even after following your most recent post.
I am getting pretty fed-up to say the least.
Any other ideas, except I remember not long after I purchased the iMAc I was needing apple help and during the attempted fix, I happened to mention that my copy of Logic Pro X was not included in the sale of the iMAC and was an add-on, and apparently this did have quite an effect to my original problem, which was purely iMAC based and Not to do with plug-ins, as i am experiencing now.
Just thought this may be worth mentioning to you??
Probably clutching at straws here, but what the ****......
