Cutoff Frequency - Roland JX-8P Owner's Manual

MIXER
This
is
where
the
volume
balance
of the
DCO-1
and
DCO-2
is
controlled.

VCF
(Voltage Controlled
Filter)
The
output
signal
goes
to the
Mixer then
to the
VCF
to
be
filtered.
Each
VCF
lets
lower frequency
har-
monics pass and cuts
off the higher ones.
In
other
words,
it
is
a
usual
low
pass
filter.
By controlling
the cutoff
point
and
resonance, the
waveform
changes, thereby the tone
color
alters.

The HPF
(High-Pass
Filter)
is
a
filter
that passes
higher
frequency harmonics and
cuts off
the lower
ones.
As
you
increase the value, cutoff point
goes
up,
lower frequency
harmonics
being cut
off.

This
is
for
changing the cutoff point
of
the
VCF.
As
you decrease the value, cutoff frequency
will
come
down, and
the
waveform
gradually
becomes
approx-
imation of a sine
wave, then the sound
will
fade
out.
