I’m going to use mine for 2, and also as an ancient 4-track. I just got an iPad mini as I’ve broken my collarbone so I can’t play my keyboard and having a month off work would drive me mad without being able to make music. I plan to use it live as a digital 4-track as I’ve found laptops to be unreliable in large venues with large bass bins (another band i’m in found a solution to this by fitting SSD RAM). As it doesn’t have the same power as Cubase 7 I’ll just bounce down groups i.e. drums, synths, guitars into separate audio tracks which should be pretty stable CPU-wise and give me more control over the sound than the current 2-track backing we’re using on a trusty old DAT player. Only got Cubasis today so haven’t had time to test out the theory
