Creating a Patch
* If you limit the keyboard area in which a tone will sound (Keyboard Range, p. 42) or limit the range of velocities for which it will sound (Velocity Range, p.
42), the result in areas or ranges where the tone does not sound is just as if the tone had been turned off. This means that if TYPE 2–10 is selected and you
create a keyboard area or velocity range in which one tone of a pair does not sound, notes played in that area or range will be sounded by the other tone as
TYPE 1 regardless of the displayed setting.
Parameter
Value Explanation
Booster 1&2, 3&4
(Booster Gain)
0, +6, +12, +18 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.

The Booster is used to distort the incoming signal.

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 Wave Gain parameter (p. 43).

Ring Modulator
fig.RingMod
A ring modulator multiplies the waveforms of two tones with each other,
generating many new overtones (in harmonic 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.
