15: 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.

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

Explanation
Adjusts the frequency at which modula-

Adjusts the amount of frequency modu-
lation applied.
Determines whether the frequency mod-
ulation moves towards higher frequen-
cies (UP) or lower frequencies (DOWN).
