A small metal ball (Pi!) rotates (circular, ergo Pi) on the inner walls of a gong to which a Korg CM-300 contact microphone is attached. Track one of two delivers this relatively realistically with reverb (lighter tones), a second track (darker tones) alienated by a DIY Clouds (all parameters controlled by an Doepfer Quad-Sinus-LFO, Pi again*).
All these circular movements (especially my hand movement of the gong to make the ball circulating) are not perfect … so they are just a very rough Approximation Of Pi.
*UPDATE: The Doepfer has no sinus, its triangle. Sorry! But triangle can be considered as a very rough approximation of sinus …
