30hz sinewave through the rotating tapetapeheads with feedback, while variating the speed.. The vari-speed is done very crudely with a switchable DC voltage source. Before I started the video I let the pitching feedback accumulate so the 30hz sine wave was turned into a broad Shepard tone with very high frequency overtones.
