Chordion makes it easy to play common chord changes in any key. In "auto" mode, Chordion's keyboard follows the chords you play, letting you strum up and down or effortlessly pluck out melodies. The built-in drum machine & arpeggiator help you keep the beat.

More experienced users will love the wide range of customization options - from the layout of chords to synthesis parameters to exotic scales. Chordion's built-in synthesis engine is highly tweekable and easy to use - create echoing lead lines, shimmery chimes, and dreamy drones. Chordion also supports MIDI, allowing you to control other instruments using Chordion's unique interface.

We appreciate your support!

Great MIDI controller


Good audio engine, good MIDI controller, good IAA features (control bar!!!). Seriously a huge fan

Great program


Really cool program! Great for getting the melodies out quickly and experimenting on the fly. Def. worth the low price.
