Chordion is a fun new way to make music on the iPad. Choose chords with one hand and play melodies with the other - never hit a wrong note! Chordion is great for performing, writing songs, jamming, or having sing-alongs with friends.

*** App Store Best of 2013 "Innovative Music Apps" in China, Japan, and South Korea ***

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!

My fave since day one 👍🏾

I’ve had this app since release and at first I just played around with it, but when I started to really experiment with my other music apps, I was totally amazed by how it would play my music apps versus me playing it directly. Another cool thing is that I can play Chordion through my DAW (Reason) and it sounds great! The Midi setup is rather simple on Mac.

I do agree with one review to have notes on the keys would be cool, otherwise I love this app and it’s not never leaving my device.

Simple and Clean

I was looking forward to the Suzuki company’s re-release of the popular Omnichord instrument coming later this year. I fell in love with the sound of the instrument as it was the first I had ever listened to when trying headphones for the first time as a kid. They became impossible to get a hold of easily since their explosion in popularity. With this elegant and beautiful app, there’s no need for it anymore. I’m very impressed!

Next generation of musical interface

I don't know many app makers as consistent and intuitive and innovative as Olympia. Chordion is yet again a true hit. It allows you to find a harmonic space and then explore that space melodically right alongside. We need more apps like this one out there, and at that really changes the way you interact with and think about music.
