  Work Details  
  Schaeffer created the phonogene. With it he was able to transpose a loop in 12 distinct steps from using a keyboard (this led to the mellotron keyboard). The keyboard selected one of 12 capstans of different diameters, like changing gears on a bike. A 2 speed motor allowed for octave transposition.
