ChordMapMidi allows you to explore chords and chord progressions in both major and minor keys, one finger tap at a time.

Note: ChordMapMidi is a midi controller. It doesn't create sound on its own. It sends commands over virtual midi to other synthesizer apps you have on your device.

ChordMapMidi is useful for songwriters, midi musicians, music educators... especially in places where the only instrument you have is the phone in your pocket.

Have fun exploring chords and progressions!

Really Amazing

I have just about every midi controller and didn't think I needed another one, but this is so very different! It does inversions and complex chordings and it is just really awesome. With this, you can choose wrong chords and actually be more musical as you hear and feel them. It is truly remarkable when paired with grain science, thumbjam, and the arpeggiator on Cassini. Don't pass up this awesome controller. On each of the pads, you can set it up to play three separate chordings as well as the inversion and octave buttons. No regrets getting this great tool.

Cool idea, but no updates for 3 years now. Thankfully virtual midi still works (for now). Also the dev promised to bring us minor key but that never happened. This really needs update for iPad graphics at least.

Developer Response ,

ChordMapMidi has been updated--February 2019. (And this version includes a minor key map.)
