Pitch
As an example, when the LFO is used to raise and lower the pitch,
you will hear a vibrato-like eect. FM (Frequency Modulation) is
an ultra high-speed vibrato. e phase of an oscillator is modulated
using the input signal from the modulator, which rapidly raises and
lowers its pitch. (is works the same as Korg’s VPM tone
generator and typical FM synthesizers.)
As modulation is incredibly fast, we hear the result not as vibrato,
but as a change in tone.
In this Operator mode, we can use the FB and WIDTH parameters
to control the amount of self-feedback and the width of the
oscillator waveform.

Modulating the amplitude of a signal creates tremolo. Ring
modulation, or Ring Mod for short, is ultra-fast tremolo. It is
historically called this because of the shape of the electrical circuit
originally used to create the eect. e input signal from the
modulators are multiplied with the carrier oscillator to rapidly
change the amplitude of the signal. As with FM, the extremely fast
modulation is perceived as a change in tonal character. e input
from the modulator(s) can be processed by a rectier, where the
“SHAPE” parameter controls the amount of rectication. e larger
the value, the more overtones will be added.
