Ratings and reviews

Wow, the way command edit is implemented is really awesome and much easier to do than on something like sunvox where you need to do a lot of fine typing and memorizing. also as someone who doesn't quite grasp hexadecimal yet, having the slider is very nice and even if I knew hexadecimal the slider is very nice on mobile over typing. really dig the whole table thing which is something I've never encountered before. the way you can set up wave tables, pulse tables, effects tables is amazing.

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
