The Xycloid Module

The Xycloid Faceplate

Xycloid traces a fixed point on the edge a circle rolling along the inside or outside of another circle.

The resulting two-dimensional shape generates a pair of complex, evolving, pulsing LFO signals.




Using Xycloid

Xycloid’s X and Y outputs are always similar, but never identical to each other. You can use relationship to create interesting interactions between parameters:

Plotting Xycloid

When plotted on a two-dimensional graph, Xycloid’s X and Y signals produce a visually pleasing shape, which can be either a hypotrochoid or an epitrochoid.

To view the shape that Xycloid produces, connect its X and Y outputs to a Scope’s X and Y inputs. Set the scope to X x Y mode. Note that the scope’s X/Y mode can also be interesting.
