Sound
and
Safe
Not
only
is
your Color
Computer
a clever creator
of
kaleidoscopic
colors,
it's
also
a
singularly
sophisticated singer
of
songs.
When
you use a
plug-in
Program Pak
cartridge, the cartridge
program
determines
the
sounds you
hear.
When
you use
the
built-in
Color
BASIC
language
(by starting-up without
a
cartridge
in
the
slot),
you can
actually
program
the
sounds you want
to hear.
Your
Color
Computer
is
a
superb
singer,
and you have
nearly
total
control
over the
quality
of
the
sound
your
TV
or
monitor produces.
For example,
type:
SOUND 39,20 (ENTER)
The computer obeys
your
command
and produces
a musical note
that lasts 1.2
seconds.
The program
is
SOUND
pitch-code, duration.
The
pitch-code
is
any
number
in
the
range
1
to
255
(1
is
the lowest
pitch,
255
the
highest),
and
duration
is
any number
in
the
range
1
to
255. Duration
sets the
time the tone
sounds
in
units of
.06
second.
Your
Color
Computer
has
quite
a
range
of
sounds.
The
following
program
lets
you hear
the entire
frequency range (codes
1-255)
that
Color
BASIC
can
produce:
