Hi there, I'm a bit of a part time musician, and I was thinking about using Garageband on my 32GB new iPad to record demos and band rehearsals etc. First question, what, in your opinion, is the best microphone to get for recording directly into iPad? Secondly, if I was to set up a mic in the middle of our rehearsal room to record our practices, would I be able to record a two hour rehearsal? Would there be enough space (I have about 12GB left on my iPad currently, but I could get rid of some stuff)? Does Garageband set any limit to length of tracks? Thanks in advance for any help.
