Recommend a compatible audio interface (2 in 4 out)

Thanks Stevo, the Alisis looks great! And has the right spec for what I’d like to do. my concerns now are if I’m going to have load each project as and when how long will that take and will the processor on the iPad 4 cope ok?

EDIT: I’ve just had a look online and it seems the alesis that you mentioned would only work with iPads that have the 30 pin dock connector, does anybody know of a solution for this? Or have alesis released a newer model supporting the lightening connector?
