Anyone else using an iOS device for music production? I've been using an a M Audio Midi keyboard and a iPod Touch. Just bought SampleTank for iPhone (http://www.ikmultimedia.com/sampletankiphone/features/) and was blown away! I ordered the iRig Midi (http://www.ikmultimedia.com/irigmidi/features/) too for 48 more sounds too! Can't wait to use this live!
How are you using your iPhone or iPod for music?
Do you intend to connect it to Arduino somehow?
Can you tell more about your ideas?
