Aggregate Device using 2 M-Audio FastTrack Pros
Hello,
This is probably really easy, but I must not be understanding something.
I have two M-Audio FastTrack Pro USB interfaces & would like to utilize all four inputs (each one has two inputs). When I try to set them up as an aggregate device in Audio MIDI Setup, I'm only allowed two inputs, even though both devices are recognized by the computer. I see both FastTrack Pros on the left-side listing, but only see one on the right-side Aggregate Device listing. My understanding is that I should see both devices on the right & I should be able to click each one, thus combining their inputs to four.
Is it that because they are the exact same model, that it is only listing one? If so, is there a way that I can utilize their combined inputs?
