I am a musician and I get a song in my head sometimes and I want to get the melody down pretty quick but no computer with a music application. thats a problem. I think it would be sweet to have a dumbed down version of GarageBand or something (I saw the iphone guitar was not impressed) but a GarageBand like interface where you could do sheet music or a keyboard would be sweet. Perfect for making a song and setting it as a ringtone on your iphone on the go. What do you guys think possible or not?
