a: LFO Phase [degree]
Offsetting the left and right phases alters how modulation is
applied to the left and right channels, creating a swelling affect.

a: LFO Waveform
b: LFO Frequency [Hz]
c: LFO Step Freq [Hz]
When "LFO Waveform" is set to Step-Tri, LFO is a step-shape,
triangle waveform. The "LFO Frequency" parameter sets the
original triangle waveform speed. Changing the "LFO Step Freq"
parameter enables you to adjust the width of the steps.
When "LFO Waveform" is set to Random, the "LFO Step Freq"
parameter uses a random LFO cycle.

d: BPM
e: Step Base Note
e: Times
The width of an LFO step, or a cycle of random LFO, is obtained
by multiplying the length of a note (r...w) (selected for "Step
Base Note", in relation to the tempo specified in "BPM, " or the
MIDI Clock tempo if "BPM" is set to MIDI) by the number
specified in the "Times" parameter.
i: Wet/Dry
The effect sound's phase will be reversed when you set this
parameter in the negative range of values.

13: St. MultiModeFilter
(Stereo Multi Mode Filter)
This is a multi-mode filter with four types; low pass, high pass,
band pass, and band reject. You can use LFO or dynamic modu-
lation to vary the cutoff frequency or resonance.
