First off, I LOVE this desk. Just got it a few days ago, and it is GREAT to get my hands on faders and really nice external EQ again. I can get a better mix in half the time. However, I am having one pesky problem that's driving me crazy and I'm hoping for some help. I am working in Logic Pro 9.1.8 with a ZED R16 (Allen & Heath). I have gotten everything up and running FROM my DAW, however, I cannot get any signal to register coming back in. I have tried everything that I know to do. I have set the ITB channel to 17/18, enabled dig send etc. Anyone with any experience who may be able to tell me what is going on would be greatly appreciated. I'm beginning to wonder if something is wrong with the dig output on my desk. Thanks in advance!
