OscilloScoop is an interactive music app for iOS that runs on the iPad, iPhone, and iPod Touch, available through the iTunes App Store. The app presents a real-time interface for creating electronic music in various electronic music genres from hip hop to techno and house. The app is designed with a minimalist modern interface of three colored crowns, that spin like potters' wheels. Touching each crown affects the parameters of the audio. The top crown controls pitch, the middle a low pass resonant filter, and the bottom a fader. Controls on the left allow one to change the bassline beat, while buttons on the right allow the user to save their creation, and a slider below controls tempo.
