In the old old days, logic could use multiple audio devices, but they couldn't communicate with one another. I believe that you might have been able to record on an audio object using one device, then move the audio file over to an audio object using the other device for playback. Unwieldy? Yes. Unusable? For me, anyway. But if you are still using some older v. of logic, it might work. Given that you are trying to use a US-122, I'll assume you didn't really like my history lesson, which leads us to workaround #2: aggregate devices. I just tried it with my system, and it seemed to work ok. In the audio/midi setup utility, go to AUDIO>Open Aggregate Device Editor. There you can merge both the built-in and US-122 devices into some aggregate device that you can name yourself. Then, in the Audio Hardware menu of Logic, select that newly-named aggregate device as your audio hardware. You now have inputs and outputs from both devices available to all audio objects. They are not labeled according to device, but just test it to see which numbered ins/outs correlate with which device. On mine, the built-in was represented by ins and outs 3 & 4. So record from 1&2 and output to 3&4. Gregory
