Brilliant set up and so easy to use. I’m a long time novice when it comes to actual musical information and am self taught so this is the perfect app to help me dive into a deeper understanding of building songs and finding more intricate ways to bring a melody to life. Thank you for the work you do, it’s inspiring the work I do
It’s fantastic!

I have searched and searched for something as good as this. The price is fair and the app is really user friendly. This has made music production so much easier and the export to Midi functionality is super great! All rounded great app for musicians and producers!

Thanks for your awesome review! 🙌
Excellent Music Tool but has some slight issues
Steve7326
The app is well thought out and useful but I can hear random static noises when playing chords and there is a bit of lag. Overall it’s not too big of an issue and the app does exactly what it claims to do. Had these issues not appeared, this would’ve been a 5/5.
Developer Response
Hi Steve7326, the app was rewritten from scratch! Sound problems are history 😊Check it out!
I can’t get back to my song

I was making a song and then I went to popular songs and clicked on one and now I can’t get back to my song. But the app is really good
Developer Response
Hey, sorry for that! You need to save your song before opening a different one. I will think about displaying a warning before opening a new song! Thanks for the feedback!
Again some minor updates to keep everything running smoothly while you write and practice.
