Which ipad mini for cubasis

hello,

I’m looking at the iPad Mini (Retina) for mobile composing and music production.

Any thoughts out there on how much memory is needed to have a good experience?

And any thoughts on the Retina Mini vs. the iPad Air in terms of size of user interface.

Has anyone found the Mini to be too small?

I’m favoring the Mini for travel, but perhaps the larger one is much better (?)

Thanks for any thoughts!!!
