Basically, I'm looking for something to easily play chords for me. In the Garage Band app for iPhone, I can go to the smart guitar and strum a few chords, but if there is any way to pan to more chords (like you can pan octaves with gestures for the piano), I don't know about it. the app only has seven or so chords listed by default on screen.
is there a way to make the app display more chords, or are those all we get? Is there a program that plays chords as easily as GB? I've found some text charts of chords online, but the midi editor I have is very basic and hard to use. My aim is to learn what the different chords sound like; not necessarily what notes comprise them.
