Perpetual Motion: Endlessly Rising/Falling Harmonizer

A Shepard-Risset glissando is a tone which appears to endlessly rise or fall in pitch. This is the sonic equivalent of a barber’s pole or the Penrose stairs seen in many M.C.Escher prints—an illusion of continuous directional motion. Perpetual Motion is a Max for Live device which replicates this effect to create epic risers or the feeling of eternal falling.

Click on the background to pause the pitch shift. While paused, click on the arrow to change direction or use the slider to change speed. Click the background again to resume motion.
