Why shapesynth? Well I really love a number of things in shapesynth, one is the tape. I’m a lover of all things tape, and the way it’s visualised on shapesynth is a thing of beauty. But, for me, being the only app I know of, music app that is, that has support for Sphero (the robotic iOS and Android ball), it’s a complete winner. For that alone.
Well worth a look at in my view. In fact, I actually bought my Sphero just to play with shapesynth, and I bought it from the app’s developer too.
