I was able to get my old Tranzport working in Cubase 7.5.20 64-bit – that’s not my issue. I haven’t used it in a few years and I am unable to record more than 1 track at once. If multiple tracks are selected and armed, when you press the record button the tracks don’t record, and the Tranzport record light goes out.
I realize that this is not a Cubase issue, per se, but I have been unable to raise anyone at Frontier Audio – as others have noted – and I wondered if I was missing something obvious. I know there’s plenty of Cubase AND Tranzport expertise on this site, so I’m hoping someone can comment.
