Last night I couldn't figure out how to configure Metro (SE 6.1.0.4) to record from USB Audio (specifically, my Griffin iMic) into Metro6, but play back to built-in audio (speaker/headphone plug). I can select one or the other, but record and play seem to move together. (Even if I've set one as input, the other as output, in the Apple Audio MIDI Setup, no corresponding choice seems to appear in Metro...)
Even better if I can set it up not only to record USB and play back through built-in, but record USB and monitor the recording in real time through built-in...
Seems like this should be trivial, but in my ignorance I can't get it to work.
