This will
require
some
careful adjustment. The final effect should be
that
as
the melody played
on
the 2600 keyboard ascends, source
A
will
grow louder, and as the
keyboard
melody
descends, source
B will grow
louder while
source
A
grows
softer. 11 A
and B
are
the same this
amounts
to
a keyboard-controlled
automatic pan. Note that the pan effect
is
independent of
whether
the
VCO-VCF-Mix-Pan-signal
path
is
actually
used
or not;
it is derived
only
from the
keyboard voltage
alone.

The
lag
processor does
not make
a
terribly
good
envelope
follower, but
it
will
make some
interesting
control
voltages
out
of
an
audio
signal.
Try
A-
it just
for the
experience.
