I'm using ACID 8, and I just replaced my old Behringer UMC22 with a Xenyx 502 mixer. The problem I'm having is that when I try to record a new track, the entire mix is recording to the new track. I've got the existing tracks (EZDrummer drum track, bass and 2 rhythm tracks) assigned to their own buses, but I can't find a way to isolate the live input..

I've been trying to think of why this is happening, and the only conclusion I can reach is that the main mix is being routed to the new track along with what I'm recording. Any ideas on how I can get a discrete track recorded here?
