Another unique app to add to my list for this year. Shapesynth is the only app I know of that works with the Sphero ball as a controller. If that wasn’t enough, it’s a pretty unique synth app. I especially love the tape controls, but you’ll need to see that for yourself I think.
Shapesynth just keeps getting better, as do many of the developer’s other apps. Take a look at them all. They’re different, and I like that a lot.
