Hello! We've got a Yamaha 01v96 w/ a 16 channel IO expansion card and 8 channels built in. We just got an Alesis HD24 and want to connect using the optical ins/outs. According to Alesis we do out from the HD24 to the in of the 01V and out from 01V to in on HD24. So, for 1-8 we have an in from HD24 and out to 01V. Same for 9-16 and 17-24. When I setup the HD24 though I am getting a "Tracks not Armed", which I am taking as meaning that it isn't getting anything from the board. So, I guess I have to tell the optical out which channels I want export? Does anyone know where to do this on the board and how to get to that spot? I look forward to hearing from you. Let me know if you have any questions.
