Customer Reviews

Excellent, but not for iOS 8

I've been using this for a while, but since upgrading to iOS 8 and 8.1 it has stopped working. In fact none of my MIDI apps work anymore with my USB MIDI interface, so I think this is something Apple have changed in iOS 8. What a pity.

Useful Test Tool

Helpful app when testing midi set-ups. Used to test rtp midi was setup correctly on my Pc... Ideal to test both note and controller data.

Ad-free Version Please

How about offering a paid alternative that doesn't pester the user with ads? This app will otherwise be a last resort for me as the constant banner ads irritate and distract.
