Ratings and reviews

Absolutely fantastic. This is becoming my favourite chiptune tracker on mobile. The latest updates, including instrument presets and SID export are just brilliant. Thankyou.

Only half a clue as to what I'm doing but this is EXACTLY what I've been looking for, a real tracker. The UI, and layout freakin' rocks it's so easy to use and making selections is incredibly smooth. Now I've only got to figure out what it do, and do what it does.

Glorious! easier to edit and has an open format. could really use the keyboard from fake sid btw
