The cross mod fader in the DDS modulator section.
CROSS MOD: This fader controls the amount of cross modulation applied
between the first and second oscillators. This parameter is useful for
creating deep FM (frequency modulation) sounds. When applying cross
modulation, DDS 2 is modulating DDS 1 with exponential FM.
When you enable the oscillator sync option for DDS 2 (see page 34), the
default cross modulation behaviour will be reversed, i.e. DDS 2 will be
frequency modulated by DDS 1.
Since DDS 2 is forced to restart its waveform cycle with DDS 1 and
DDS 1 is responsible for the base frequency when oscillator sync is
enabled, any changes applied to DDS 2's settings will change the
harmonic content of the sound the depth of which can be controlled
by the CROSS MOD fader. De facto, this allows for a well-behaved
type of frequency modulation whose sonic outcome might resemble
the results of wave folding or phase modulation.
