I am considering getting an iPad mostly for recording guitar. I have an Android tablet so for everything else I am set, I am really just trying talk myself into this because I know iPads are better for some things, including recording.... but I have a budget. My question, for those who multitrack on their iPads, What should I place more importance on... The more powerful iPad Air (64gb) or the storage space of the regular iPad (128gb) ? Will I just keep filling up the storage on a 64GB ? (with DAW, photo editing apps, and of course multitrack recordings). My Android tablet has removable microSD so storage is never an issue, and I'm not sure what to expect. Plus I don't record on it so those file sizes are an unknown to me also. BTW, the Air/256, and the Pros are not of interest because I don't know how much I will actually end up using this and thus they are more than I want to pay. Thank you.
