About LFO
The LFO (low frequency oscillator) is a low frequency
waveform that is used to modulate, or regularly waver,
some aspect of the sound.  This modulation can be applied
to the level (Amplitude), pitch, or tone (Filter).

The LFO here is separate from the modulation found in the
Common page’s Control menu.  (See page 46.)  The LFO
modulation here is applied constantly and is not affected by
the controllers (MODULATION wheel, after touch, PITCH
wheel, or Foot Controller).

●

Range: 0 — 127

This determines the amount of time before the onset of the
LFO modulation.  (This only affects Pitch modulation.)

●

Settings: sawtooth, triangle, sample & hold (S&H)

This determines the particular waveform for the LFO.  The
modulation characteristics differ depending on the wave-
form selected.  The sample & hold setting produces a
random modulation effect.

●

Range: 0 — 63

This determines the speed of the LFO modulation.  Higher
values result in faster modulation.

●

Range: 0 — 31

This determines how widely the level (Amplitude) is
modulated by the LFO.  The higher the value, the greater
the modulation of the sound level .

●

Range: 0 — 63

This determines how widely the pitch is modulated by the
LFO.  The higher the value, the greater the pitch modula-
tion.

●

Range: 0 — 15

This determines how widely the tone (Filter) is modulated
by the LFO.  The higher the value, the greater the tone
modulation.
