Enjoy Exploring Chords and Progressions!
1 - ChordMapMidi is a midi controller app for iPhone which allows you to explore chords and progressions, most of the time playing with just one or two fingers.
2 - ChordMapMidi doesn't make any sound on its own. Instead, it sends midi signals to another app, a synthesizer app, running in the background.
3 - The recommended way to get started is to read this 6-page pdf document. (If you can print a copy for reference, that's even better.)

4 - The chord flow in ChordMapMidi is based on the concepts presented at ChordMaps.com (particularly parts one through five). We recommend reading those five parts, if you haven't yet.
