Cross modulation by a sine wave
cannot be applied to a vocoder pro-
gram.
Since a sine wave contains no
overtones, the filter will not
modify its tone.

Select HPF or BPF as the filter, and
adjust "Cutoff" to create a vocal-
type sound.

is used as the modulation source for
an oscillator, but Cross Modulation
lets you use another oscillator as the
modulation source, creating sounds
with a complex overtone structure
that would not normally be produced
otherwise. On the microKORG, you
can use oscillator 2 to apply cross
modulation if a sine wave is selected
for oscillator 1. Gradually raise the
"CONTROL 1" level, and notice how
the sound changes. This can produce
distorted sounds, or sounds with a

You can also achieve interesting re-
sults by applying sync modulation
and cross modulation at the same
time.
