Users of EonCloud's free beats app Awe Beats (available on iTunes) have been able to listen to their creation on the iPad and most have exported their files to the desktop or laptop for further music production.

A pro-tip for those serious with DJ and music production is to use a USB audio interface. For this, many prefer Focusrite.

The following is a description of one of their popular product:

Scarlett 2i4 is a 2 in / 4 out USB audio interface featuring two award-winning Focusrite pre-amps and four high-quality audio outputs. Housed in an anodised aluminium unibody chassis, the Scarlett 2i4 is the perfect audio interface for musicians and digital DJs.
