Traktor s2 emergency backup

Hey guys! I'm thinking of buying an s2 but I found out i can't plug in a backup devise like an iPod or ipad. This scares me because I'm a mobile DJ and if I can't have a back up ready to hit play if my laptop crashes. Is there a solution for this? If not would it be wiser to get the novation twitch cus of the backup? All advise will be greatly appreciated :) thank you

Only way around this is to use an external mixer. You can do a small behringer for around fifty bucks... I think art makes a really small passive mixer that would probably do the job too and be space efficient.

That's what I was kinda thinking about...
