Booster (Booster Gain)

When a Structure Type of TYPE 3 or TYPE 4 is selected, you can adjust the depth of the booster. The booster increases the input signal in order to distort the sound. This creates the distortion effect frequently used with electric guitars. Higher settings will produce more distortion.

What is a Booster?

The Booster is used to distort the incoming signal.

Booster level

In addition to using this to create distortion, you can use the waveform (WG1) of one of the Tones as an LFO which shifts the other waveform (WG2) upward or downward to create modulation similar to PWM (pulse width modulation). This parameter works best when you use it in conjunction with the Gain parameter (PATCH/WAVE/WAVE) (p. 81).

What is a Ring Modulator?

A ring modulator multiplies the waveforms of two Tones with each other, generating many new overtones (inharmonic partials) which were not present in either waveform. (Unless one of the waveforms is a sine wave, evenly-spaced frequency components will not usually be generated.)

As the pitch difference between the two waveforms changes the harmonic structure, the result will be an unpitched metallic sound. This function is suitable for creating metallic sounds such as bells.
