Effect

Synth LFO

The LFO is the oscillator that creates a swelling sound.

By greatly increasing the values for parameters such as

VCO vibrato, PWM depth, and LFO depth (explained

below), you can get various kinds of vibrating sounds

(periodic, cyclical changes) in tone and pitch.

Waveform

Sets the waveform of the vibration.

fig.10-35e

Rate

Sets the rate of the vibration. When set to 0, the rate is

approximately 0.1 Hz (10 seconds per cycle), and at a

setting of 100, the rate is approximately 20 Hz (20

cycles per second). In Tempo Sync this is disabled, and

you cannot make this setting.

Value: 0–100

Tempo Sync

This setting synchronizes the rate to the tempo of the

song. When not synchronizing, set this “Off.” When

you select the note, the rate setting is disabled, and the

rate is set the note length corresponding to the tempo.

When synchronizing to a song’s tempo, if the length of

the note is set longer (or shorter) than that of the

possible range of rate settings by the change of song

tempo, the rate can not correspond to the note length.

Value: Off, -

If “?” appears before the note symbol you set, it is because

the upper (or lower) limit of the setting range has been

exceeded, and that the synchronization is not correct.

Furthermore, the precision of the Rate setting and song

tempo differ. If left to develop over long periods, the two

may gradually drift apart.

Delay

Sets the elapsed time between the moment Trigger In

turns “On” and the point at which the modulation

from the LFO reaches the designated depth. As the

value is increased, the elapsed time increases,

gradually deepening the swelling.

Value: 0–100

Depth

OSC1/OSC2

Sets the depth of the OSC1 or OSC2 vibrato (the

cyclical change in pitch caused b the LFO).

Value: 0–+100

VCF

Sets the depth of the vibrating cutoff frequency by the

LFO. As the value is increased, the cyclical tone change

gets bigger.

Value: 0–+100

VCA

Sets the depth of the wavering volume (tremolo effect).

As the value is increased, the variation in volume

increases.

Value: 0–+100

Tri (Triangle wave)

Sqr (Square wave)

SAW (Sawtooth wave)

S/H (Sample and Hold

creates random change)
