A stereo delay with resonant filters and fractally modulated panning.

The delay times are set through the bpm control and the divider adjustment. Triplet and sixteenth settings create a dotted rhythm. With every beat, the filter resonance frequencies are retuned to random steps on an equal-tempered chromatic scale, to the reference set through the tune control.
