DO
NOT,
for
the
present,
USE
THE
KEYBOARD.
For now,
your
experiments should
be
directed toward
familiarizing
yourself
with
the
SOUND-GENERATING
CAPABILITIES of
the
2600.
A
synthesizer
keyboard
Is
M1SLEADINGLY
FAMILIAR
and doesn't
reall>
operate the way
any
other
keyboard
does, and
you'll
find
out
soon
enough just
how
it
does
operate.

The
3604 keyboard
unit
works
something
like
the frets
on
a
rubber
guitar,
turned
inside
out.

In making
use
of the
ADSR
and
AR control
inputs
to
anything,
set the
SWITCH
just under
the
ATTACK-RELEASE
box to
its UPPER
position.
Then use the
MANUAL
START
button
to initiate an enve-
lope
output
from
either
the
ADSR envelope
generator
or the
AR
generator.
Do anything:
punch
it,
hold it down,
or tap
it repeatedly.
3.234
Follow
prewired
connections
BACKWARDS to their
sources.
Many
of
the
VCO
outputs, for example, are
not prewired
to
any input
at all,
and
it
would be
a waste
of time trying
to
find
out
"where it all
goes".
But
most of
the input jacks
do have
a
prewired connection
which
you can trace
back from
the boxes
and labels just beneath them.
3.235
For every
effect you hear,
ask
yourself which 2600
function is
creating
which
part
of the effect.
It
will help
to draw
or imagine block
diagrams
for
each sound.
