Booster 1&2/3&4 (Booster Gain)

When a Structure Type of ÒTYPE3Ó or ÒTYPE4Ó is

selected, you can adjust the depth of the booster.

This can be set for the pair of tones 1 and 2 (Booster

1&2) and for the pair of tones 3 and 4 (Booster 3&4).

Range: 0, +6, +12, +18

Higher settings will produce greater distortion.

Booster

The Booster is a function that increases the input sig-

nal in order to distort it.

fig.3-69

In addition to using this for distortion, you can use the

waveform of one of the tones as an LFO to shift the

other waveform up and down, producing an effect

similar to PWM (Pulse Width Modulation). This is

even more effective when used in conjunction with the

Wave Gain of the WAVE/FXM section.

Ring Modulator

The ring modulator multiplies the waveforms of two

tones to create many new overtones that were not pre-

sent in either of the original waveforms (inharmonic

overtones). This is suitable for creating unpitched

metallic sounds such as bells.

Stretch Tune (Stretch Tuning Depth)

Select the stretch tuning curve. The selected curve will

affect the way that chords will sound.

Range: OFF, 1Ð3

When this is ÒOFF,Ó equal temperament will be used.

As the value is increased, the pitch difference between

the high range and low range will increase.

Stretch Tuning

Stretch Tuning is a method of tuning used only on

pianos. In general, pianos are tuned so that their high

range is sharper and their low range is flatter than the

equal tempered pitch. This makes chords sound better.

V-Priority (Voice Priority)

Specifies how notes will be prioritized when the maxi-

mum simultaneous polyphony (64 notes) is exceeded.

Available settings:

LAST: The last-played notes will take priority. If

more than 64 notes are played, the first-

played notes will be turned off succes-

sively.

LOUDEST: The loudest notes will take priority. If

more than 64 notes are played, the notes

with the lowest volume will be turned off

successively.

Key Range L (Key Range Lower)

Specifies the lowest note that the tone will sound.

If a note below this setting is played, it will not sound.

Range: C-1ÐUPR

Key Range U (Key Range Upper)

Specifies the highest note that the tone will sound.

If a note above this setting is played, it will not sound.

Range: LWRÐG9

By using Key Range Lower and Key Range Upper,

you can cause different tones to sound in different

areas of the keyboard.
