Ableton Setup Questions

[legunner]

Hey guys just confirming with some of you guys if this would work:

My cousin is playing with my S4 for 2 hours on my macbook using traktor, Then after him i intend to plug in my APC40 in to an empty usb port and boot up ableton then start playing using my s4 as a soundcard just to go through the master out.

Would this pose any questions or is it just as simple as this?

can't see why it won't work if you config it correctly

[Jaz]

yeh it seems to work in my head, as long as you have the midi interface settings and soundcard settings configed right

why not just try it?
