I am trying to set up a bus for reverb in Luna and I can "send" no problem from my sources however the "input" for my bus is limited to "summing". It offers me an API or a Neve plugin trial but I do not want them! All I want is to be able to set the bus input to channel 3-4 or 5-6 or ANYTHING! When I click " none", that's what I get is none! Am I missing something? I set my send outputs to, say channel 5-6 and expect to set my bus input to channel 5-6. Is that so crazy? Help?
