UR 44 Outputs 1-2, 3-4 bleed

Hey there. I’ve got a UR44 unit that I’m looking to pass a guitar, bass and electronic drum kit through using Apple Mainstage. The house only outputs mono so that’s all I need.

Today was the first test. I had my guitar line-in on 1 and the drums were in with midi. I had sent the guitar through 1-2 and the drums on 3-4.

For some reason, the UR44 wouldn’t allow the 3-4 signal (drums) to be without the guitar signal (1-2). But the reverse was fine,1-2 was without drums.

Ideally, I’d want to run guitar out on input 1. Drums out on input 2. Bass on output 3… and so on all mono,

Is this possible? Thanks

Bump. I’m still having this issue and I don’t know how to solve it.

Just to reiterate, though it’s specified above, I’m trying to output unique signals from 1 (guitar) and 2 (drums) but i will get the signal from 1 outputted in 2. Basically, the drum track has the dry unprocessed guitar signal in it as well. halp!
