PLAYlogo: PanPong~.pd

The pan of each oscillator for each "sound circle" is driven between full left and right according to both the index of the ring and a "wavelength" of the pan, so outer rings pan faster than others in time. However, all pans converge on 0 as the ramp arrives at 1. And yes, it's a pun on PingPong, as in PingPong-delay, but for Pan.
