Mod./P.Shift

This effect modulates the volume level of the input signal.
The effect is stereo, and offsetting the LFO of the left and
right phases from each other produces a tremolo effect
between left and right.

a:LFO Waveform
This parameter selects the LFO waveform. Vintage wave
simulates the characteristics of the tremolo created on a
guitar amplifier. Combining this effect with the Amp Sim-
ulation will make a realistic, vintage tremolo amplifier
sound.

b: LFO Phase [degree]
This parameter determines the difference between the
left and right LFO phases. A higher value will simulate the
auto-pan effect in which the sound is panned between
left and right.

This effect uses the input signal level to modulate a stereo
tremolo. You can simulate a tremolo effect that becomes
deeper as it fades out while the level gets lower.

d: LFO Frequency [Hz], d: Envelope Amount [Hz], 
e: Depth, e: Envelope Amount
These parameters set the modulation via an envelope
(input signal level).
The “LFO speed” is obtained by adding the “LFO Fre-
quency” value to the “Envelope Amount” value multi-
plied by the input signal. The LFO modulation depth is
obtained by adding the Depth value to the “Envelope
Amount” value multiplied by the input signal level.

•

The following example indicates that the “Depth” is 0
with an LFO Frequency of 1.0Hz and the maximum
input, and that the “Depth” is 100 with a Frequency of
8.0Hz with zero input.

“LFO Frequency [Hz]”=8.0, “Envelope Amount [Hz]”=–7.0
