Using Ableton Live 9 and brand new to it. Was watching Matt McCoy on http://www.youtube.com/watch?v=THJvpxZQ4lI and he routed the cues to left and loops to right via the "Audio to" drop down/ External Out option. I would've used the pan knob on each channel for the same connections (out via the Mac's headphone out).
What's the difference here? Any pros or cons for either?
