Djam. Used the Figure app from Propellerhead for the drum & bass. Used Amplitube for guitar. Quick fun...all improv. I may go back and tweak the drums. Using Audiobus, it's easy to record from Figure into Amplitube. I looped the drums and recorded about 5 minutes. Then recorded the bass next to the drums. With the multitrack, create several drum patterns in Figure, recording each one to it's own track. Gotta love Audiobus!
