User reviews

I love this app!

Beautiful sounds and cool layout. Strum with the thumb to play chords or pick out single notes. Nice work. Love it.

Love this... has potential to be amazing!

Totally worth the 1$ however I’d gladly pay more if it added the suggestions in other review like velocity and sustain controls and a few more. Something like the kaoss padkontrol that easily changes 2 selected variables like volume and pitch on a finger controlled axis. It would be cool if on top of each string it had a tiny display of the tuning/note. It would really cool if you could add a little scroll wheel or up down arrows to the top of each to individually tune each string for custom arrangements. Also if you could drag the strings around to rearrange them on the fly. Would be Maybe add a lock 🔒unlock button so you could use it live and not accidentally worry about moving a random setting or tapping a button. Last idea maybe a double of triple strings button feature that makes the thing have that angelic hammered dulcimer style abilities. Think twelve sting guitar just extra added strings tuned same.

Still gave it five stars because it’s ease of use and such a value. I think it could become a useful song creation idea tool with a few added updates. Also could be a good education tool for music theory.

Thx for developing this!

Great but broken

I have been using this app for several years now. For a singer that can’t play an instrument it is important to utilize what we can. This app made it possible too input my notes and practice my songs. Only issue I have now is I can’t seem to save or share songs. I can’t rename a song so I can keep it. I used to be able to do this feature but since the app hasn’t been updated in 5 years it’s not working. I wish the developer would check that out because some people still would like to continue using this app.

No help or support.

I kind of believe I was mislead thinking purchasing full version would let me record and save things. It's a cool app but kinda pointless if all I can do is strum around and not record anything

Awesome concept

The amount of customization options is impressing. My only complain is that when strumming the same chords multiple times, there's a very audible popping sound as notes get cut off.
