Multiple outputs and recording

I'm having some trouble recording straight into arrangement view from Drumazon. I have it set up with multiple outputs on separate tracks but when I hit record the clip is transparent/greyed out. The sound only appears to be coming straight from Drumazon, rather than me being able to record it in and it played from that.

I don't usually use session view, surely there's a way to do this in arrangement? As usual its probably really simple when you know how.

Thanks in advance for any help.

Sorted. Delete thread please.
