Howdy! Hope you had a great xmas. I have apps such as nano studio, garageband .while Animoog whould have been ideal(it now has a four track recorder),
It doesn't pickup my bass via the irig.
What i am after, is for an interface/app for ipad which allows me to record the usual keys/drums but also picks up my bass via irig.

Has anyone got any ideas?

Garageband doesnt do bass amps (a crime imho),and i want something with everything on a line recording wise.

Cheers

Maybe this should be moved to the recording section?
