When you press a button in the FM section, it
will light up to indicate that the correspond-

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.
