Perpetual Motion

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.

You will need Ableton Live Suite OR both Ableton Live Standard and Max for Live to run this software.
