Other modulation and pitch shift effects
32: St.Tremolo
(Stereo Tremolo)
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 Wave
This parameter selects the LFO waveform. Vintg (Vintage) wave
simulates the characteristics of the tremolo created on a guitar
amplifier. Combining this effect with the Amp Simulation will
make a realistic, vintage tremolo amplifier sound.
b: LFO Phase
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.
33: St.Env.Tremlo
(Stereo Envelope Tremolo)
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.
e: Freq, e: (Envelope Amount), f: Depth, f: (Envelope Amount)
These parameters set the modulation via an envelope (input sig-
nal level).
The “LFO speed” is obtained by adding the “Freq” value to the
“(Envelope Amount)” value multiplied 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 8.0 Hz with zero
input.
“Freq”=8.00 Hz, “Envelope Amount”=–7.00
“Depth”=100, “Envelope Amount”=–100
