ShapeSeq is a wonderfully simple sound sequencer created by Paul Apfrod using openFrameworks. Primitive shapes represent four oscillators you can choose from. 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.
