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.
