When you press a button in the FM section, it
will light up to indicate that the correspond-
ing item can be set. You can then use the
DATA ENTRY sliders to change the settings
of individual parameters.

The FM tone generator
FM stands for “frequency modulation.” This
type of tone generator modulates the fre-
quency of a sound’s fundamental waveform
of a sound with a different waveform to pro-
duce a totally new one. Waveforms are gen-
erated by “operators,” of which the reface
DX has four. An operator that generates a
fundamental waveform is a “carrier,” and an
operator that modulates these waveforms is a
“modulator.” Each of the four operators can
be used as either a carrier or a modulator. By
changing the way operators are combined
and further modulating with other elements
such as levels and envelopes, you can make
sounds change in a highly complex fashion.
