This has the potential to be a powerful midi controller... If only the developer will beef up the midi, add more control over the chords, and allow us to mute the internal sound, it could be a fantastic, flexible, and dead simple way to control other apps and send midi to external DAWs. As it is, it's a nice harp app that I doubt will appeal to many real harp players or novices wanting to get that sound due to its look and modest complexity... But if it just went a bit further (imagine if each performance partition could have its own midi channel for example) it could be a hero of the alt controller arena. Well, I can dream.
