Here's the latest: I think I have a problem with my Zed and not Sonar. I just got home from work and decided as a troubleshooting excercise to see if I plugged a mic into channel 11 on the Zed, then set the Input of channel 1 in Sonar to 'Zed Left 11/12', would I get my signal on channel 1 in Sonar? I got nothing, but continued experimenting.
When I plugged my mic into channel 13 on the Zed and did the same experiment trying to route it to channel 1 in Sonar, all of a sudden I had a signal.
Then I checked to see if I had a signal on channel 13 in Sonar.
I continued, and I found that in actuality, I am able to get signal through the Zed into Sonar on my upper 4 channel strips, and Sonar responds as it should.
So - my Zed seems to work fine for channels 1-8 and 13-16. It won't work for me if I'm plugged into channels 9-12.
Now I'm wondering if there is something electronically connecting the channel strips in groups of 4?: My first two groups of 4 work (Ch. 1-8), the next 4 don't work (9-12), and the last group of 4 work (13-16).
There is a humongous thread on Gearslutz with the Allen and Heath Zed R16 as its subject. The A&H rep has responded there before, so I'm hopeful he'll see my post over there and respond.
Thanks for the help. I was pretty darned sure that I had the routing in Sonar as it should be, but it's upsetting that my Zed might be screwed up.
