ShapeSeq is a fun and simple new kind of musical instrument for the iPhone and iPod Touch. There are four primitive shapes to choose from representing four oscillators. As each shape is moved around the screen, the pitch and volume moves with it.
Every shape has it’s own loop, and every movement is recorded on the loop for instant playback. As the loop can be varied by size and number of steps while it is playing, all kinds of new sounds and effects emerge.
