Only 3 instruments on iPad Air
I have just bought an iPad Air. I've seen that with iPad Air, I get couple of apps for free. One of them is GarageBand. The problem is, it is free indeed but only offers 3 instruments. The app is already free on all iDevices with 3 instruments. Why don't I have all of them? I'm not going to purchase the instruments because I bought an Air, supposedly having exclusive free apps.
GarageBand (iPad), iOS 7.0.4
