Creating a Patch
fig.Struct-10
This type passes the filtered sound of each tone through a ring
modulator to create new overtones, and also mixes in the sound of
tone 2 (4). Since the ring-modulated sound can be mixed with tone 2
(4), tone 1 (3) TVA can adjust the amount of the ring-modulated
sound.
• If you select a tone while on the Structure screen, the tone paired
with the selected tone will also be selected.
• When TYPE 2–10 is selected and one tone of a pair is turned off,
the other tone will be sounded as TYPE 1 regardless of the
displayed setting.
• If you limit the keyboard area in which a tone will sound
(Keyboard Range p. 48) or limit the range of velocities for which
it will sound (Velocity Range p. 48), 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.
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.

Booster
The Booster is used to distort the incoming signal.
fig.Booster-1.e
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. 45).

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.
