I play in a band that gigs often, usually 6-8 x per month. I have a Line 6 mobile keys 25 keyboard and would be pretty cool to use live with GarageBand. I currently have an iPad 4 that I will use to experiment my idea with, but it is my work and personal device so I'd probably end up getting something specifically for the band. Has the iPad mini been reliable for everyone? I'm not sure how much power the line 6 keyboard draws, but I assume the battery life from the mini should withstand 2.5 hrs straight of music? Has anyone tried using an iPad live for music production? Thanks!
