USING EXTERNAL EQUIPMENT. We give
a
few general
patches
here, in
two
categories. In the first are
all
those
patches in which the
2600
is used to
modify
externally generated
signals from e.g.
electric instruments
or tape
recorders. In the
second
are all those
patches in
which
external
equipment
is used
to
modify
or
to store signals
generated
by
the
2600.

I*
The basic patch for
using
an
external
source to control
some
operating
function of the
2600.
The
Microphone Preamp
may
not
always be necessary;
but
the use
of
the
Envelope Follower is essential.
Experiment
with
the
VP
lag
in
and
out of
the circuit-its only function here
is to
smooth
out
the
EF
output a
fittle.

An obvious improvement on No. I. If,
for
example, source
B is a
Hammond,
or the vocals
of
a
rock group, and source
A
is
a lead guitar, then the
guitar
envelope
will modulate the
organ or vocal
sound.
There are innumerable
possibilities contained even in such
a
simple patch as
this
one.
