yes. you dont even have to record on the hd24. just plug in your analog inputs to the back of the hd24. record enable whatever tracks you plugged in to. record enable the new track in cubase. select whatever input the signal would be coming in on. dont forget to set your sound cards clock to external digital in. the analog inputs on the hd24 will be mirrored in the digital outs. make sure input monitoring is enabled too.
