RING MODULATOR

This is an effect that applies amplitude modulation (AM) to the input
signal, producing bell-like sounds. You can also change the
modulation frequency in response to changes in the volume of the
sound sent into the effect.

STEP RING MODULATOR

This is a ring modulator that uses a 16-step sequence to vary the
frequency at which modulation is applied.
