ARP 2600 - Function Operating Characteristics; Overview of Voltage-Controlled Functions

27
4.0 IN
THIS
SECTION we
will discuss in
detail the
operating
char-
acteristics of
each
separate
function of
the
Mode!
2600.
4.01
BY THIS
TIME
you should have
experimented
in
some
measure
with
the
operation of
the
2600
through
its
built-in
p3tch, and
you
should
therefore have
some
idea
of the enormous
variety
of
-sounds
the 2600 can
generate.
4.02 MORE
IMPORTANT,
HOWEVER,
is the fact
that
you
are
be-
ginning
to
get
an idea
of how
the individual
function*
can operate
on
each other
to
control
the
audio
output from
the
2600.
4.03
That is
important
because
throughout
this
section
we are going
to
describe
each
function
mainly
in
terms
of
what
it
does
to WAVE-
FORMS-NOT
in
terms
of what
"sounds'*
it makes,
or
what
it
does to
"sounds".
You
should be able
to
understand
why
such
an approach
would
be
hopelessly
complicated:
refresh your
memory

necessary

4.04 Think of
this section
as a
REFERENCE
section.
As you
gain
familiarity
with
the
2600,
and
particularly
as you
gain
experience
in
translating
from
the
language of
SOUNDS to the
language
of WAVE-
FORMS
and
back
again,
you will find
that
this section
will
become
more
and more
valuable
to you.
For
THE MORE
CLEARLY
YOU
UNDERSTAND each
function
PURELY
IN
TERMS
OF WAVE-
FORMS, the
more
clearly
will
you
see
the possibilities
for
NEW
PATCHES
and
NEW
USES
for
each
function
in the
2600.
4.1
Five of
the
2600 functions
are
voltage
controlled-
these are the
three
VCO's, the VCF,
and
the VCA.
