I'm hoping to take full advantage of Garageband on my new iPad 2. While it will be fun using the built-in instruments, I'd really like being able to use my own. I've done some searches, only to come up with mixed results. I'd like to know the best solutions for recording from an external mic and from a digital piano? I have the camera connection kit, but I've read that there are specific requirements due to usb power, etc. Specifically, What is the best way to hook up an external mic for recording voiceovers and stereo sound from an instrument like a digital piano? I'm no so much concerned about MIDI input, but I would like to do multi-track audio recording using my piano and a vocal microphone. Solutions? Thanks!
