ARP 2600 - Controlling VCA Gain with VCO2 Sine Wave

62
Now
add
one connection:
take
a
patch
cord
and connect the
VC02
sine
output
to
the
linear
control
input of the
VCA. Set VC02
to
its
low-frequency
range and the
initial
frequency slider
to
anywhere
near center.
Set
the VCA initial
gain
about one-third
up.
As
your
signal source use
the noise generator; open
the NG-
Filter
input and
close all
the
other filter
inputs. Set
filter
resonance at
minimum and
initial frequency at maximum.
Now open the VCA
linear
control input
attenuator
about
half-
way. This
should
introduce a slow
undulation into the
volume of the
noise
you
are
listening
to:
the
slowly
undulating
output
voltage of the
VC02
sine
wave is increasing
and
decreasing the gain
of
the
VCA.
