Ring Modulation is a classic synthesis technique that takes two
source waveforms and generates a third waveform, which contains
the sum and difference frequencies of the two inputs.
At audio rates, ring modulation creates a fairly inharmonic and
‘metallic’ sound. At LFO rates, ring modulation can generate
interesting, complex modulation shapes.
[1] IN X - First of two Ring Modulator inputs. The input is DC
coupled, so you can ring mod slower sources (like LFOs), as
well as audio rate signals.
[2] IN Y - Second of two Ring Mod inputs. This, too, is DC
coupled.
[3] RING OUT - Output of
the Ring Modulator,
which is a waveform
containing only the sum
and difference
frequencies of the two
input waveforms, as
shown in the illustration
to the right.
[4] OUTPUT LED - Color
indicates the polarity
(green = pos; red = neg)
of the RING output, while
intensity indicates
amplitude. At audio rates,
the cycle is too high to
see the individual peaks
and troughs (meaning it
acts mostly as an output
indicator). But at LFO
rates, the LED provides a
visual representation of
the complex LFO shape
being generated by the
ring mod.
