### 1/5 — Sad

*2020-05-21, version 4.2*

Unsupported, and C2 doesn’t send midi.  Huge potential, wasted.

### 5/5 — Best Harp app I've tried so far

*2016-05-24, version 4.2*

This is the best harp app I've used so far and this one is the fourth or fifth I've played with. It may not have all the bells and whistles of some apps but it makes up for all that by it's playability. Thanks to chord masking and chord presets I found I was making good sounding music almost immediately. In addition, the harp samples sound good, even through a combo amp.

I would like to see the interface brought out as a separate MIDI controller app with more chord options. This app gets a solid five stars.

### 3/5 — Lots of Potential

*2014-07-13, version 4.0*

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.

### 5/5 — Thanks for an awsome app!!!!!

*2012-03-29, version 2.0*

I love his app, the sound of the harp is absolutely unbelieveable. Buy this app now, it is worth every penny.  Thanks guys!!!!!!

### 4/5 — Pretty good but wish for more chords!

*2011-09-03, version 2.0*

I would love to use this app playing live but it is very limited on chords. Please expand our choices to include D, E, A major chords. Other than that, very cool app- great interface. Please make multiple touch more responsive. I'd love to do doubles and arpeggios.  Thank you!  :)

### 4/5 — Very good

*2011-03-02, version 1.0*

Very well conceived, good sound, 
Needs to be able to change tonality or build you own scale.

### 5/5 — The Best Digital Music Instrument I've Ever Used.

### 5/5 — great

*2011-02-23, version 1.0*

### 5/5 — Excellent

*2011-02-23, version 1.0*

Great sound. Intuitive. Love being able to have different chords and scales on the screen all at the same time. Nice visual effect on the playing surface. Good job! If you want to play the harp in a brand new way, GET IT!
