Hey!
I’m releasing my interpretation of a tone matrix app. You simply flip between instruments and touch the grid to start composing music.
I tried to keep the mechanics and user interface as clean as possible. I think compared to many other matrix apps out there this one is much easier to play around with.
I’m keeping this one free, it was more of a little side project, but I’m happy with the result. In hindsight next time I’ll use MIDI sounds I think, Coronas (hidden) sound API is rather limited.
