Creating a Patch

Booster 1&2, 3&4 (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.

Value:

0, +6, +12, +18

Key Fade Lower (Keyboard Fade Width

Lower)

This determines what will happen to the tone’s level when a note
that’s lower than the tone’s specified keyboard range is played.
Higher settings produce a more gradual change in volume. If you
don’t want the tone to sound at all when a note below the keyboard
range is played, set this parameter to “0.”

Value:

0–127

Key Range Lower (Keyboard Range Lower)

Specifies the lowest note that the tone will sound for each tone.

Value:

C-1–UPPER

Key Range Upper (Keyboard Range Upper)

Specifies the highest note that the tone will sound for each tone.

Value:

LOWER–G9

If you attempt to raise the lower key higher than the upper key,
or to lower the upper key below the lower key, the other value
will be automatically modified to the same setting.

Booster

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. 63).

Ring Modulator

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.
