Can you use 2 Controlers on one system?

LordOfPeanuts

Hi I'm planning on gifting my Traktor Kontrol S3 to a friend who has the same Controler. I was wondering if both can be used simultaneously using Traktor Pro 3? I'm aware the S3 has 4 channels but I was thinking on the the lines of him using them like a 4 deck Controler/CDJ without having to switch from A/B/C/D? For example; left controler on A/B and right Controler on C/D Channel.

Any help and/or instructions on how to achieve this would be welcome. TIA

I've successfully played B2B sets on a single computer with two controllers, so it is possible in general, although I am uncertain whether Traktor would be able to discern between two controllers of the same model.
