Excellent tool

I have enjoyed this app for years, and it continues to be one of the most useful tools I have for composing and studying chord progressions and voicings when away from a piano keyboard. Use it with the built in sounds for convenience, as a controller for other iOS music apps, or combine this app with the musicIO MIDI app, and a wired connection from iPhone or iPad provides a rock-solid, low-latency connection for chord input to your computer's DAW. MIDI over WiFi is also possible.

The developer is accessible by email and is very responsive to bug reports—hence the recent update with a minor bug fix. The app has received many updates and improvements over time. Well worth the price.

Awesome app with great service

This app with audiobus, korg sound module and a midi foot controller has replaced my korg keyboard for gigs. Amazing service as well. All my questions were answered within 24 hours. I am totally impressed.

Best chord app yet

I've tried a plethora of chord and scale apps. None of them has the versatility of this one. The only thing that holds me back from 5 stars is the ability to play the single notes of a chord. It would be great if there was a switch on the chord note keyboard that would change it to the keys of the note of the chord selected.
Chordion has that feature but this app, which I just bought because Chordion 2 hasn't come about, is still much better than Chordion. Love the app and some of the internal sounds are pretty darn good!
