I have inherited a recording studio project within a youth centre. Currently nothing has been put together but items (still boxed) where brought a couple of years ago. Two items are O1V and HD24. I recognise that a card is needed to connect the two things together using the optical. The MY16-AT card has been suggested. This has two sets of ins and outs for channels 1-8 then 9-16 so what happens with the 17-24 channels on the HD24? Do I loose these, so end up with a 16 track instead of a 24 track machine? Please please help me, it will be massively appreciated not only by me but by the que of 16 -18 year olds desperate to get their band in the studio. Thanks. Paul
