Fingerlab who makes some of my favorite iOS app (DM1 and Multipong) have released Rockmate. This looks like a really fun app. I can’t wait until the next time my brother is in the room with me.
“You can compose, record and play songs with up to 4 Rock players on one single iPad. Rockmate is easy to play with smart chords progressions, sounds great with separated guitar effects and in-house produced audio samples and is also fully customizable with multiple drums and keyboard styles.” – fingerlab.net
