Random Filter)
This stereo band pass filter uses a step‐shape waveform and
random LFO for modulation. You can create a special effect
from filter oscillation.
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 Frequency [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
Frequency parameter enables you to adjust the width of the
steps.
When LFO Waveform is set to Random, the LFO Step
Frequency 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 (…) (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 range of values from –Wet to –1:99.
