table Stereo Musical Instrument is a
state-of-the-art keyboard with many
exciting features. You can set the
keyboard to sound like 100 different
musical instruments or sound effects.

Your keyboard’s features include:
100 Prerecorded Tunes — let you
hear a sample of what you and the

tunes either one at a time or consecu-

play along with the tunes.

board to sound like anything from a
harpsichord to a honky-tonk piano.

ate almost any type of music.

or slow down the tempo of any select-
ed music pattern.

steady beat for many styles of music

Transpose Function — lets you in-
stantly change the key of the music,
even while you are playing.
Two Built-In Speakers — provide

music come alive.
Headphones/Output Jack — lets

play without disturbing others, or an
external amplifier so you can play for
a crowd.
Three Power Options — let you
power the keyboard from internal bat-
teries (not supplied), standard AC
power (with an optional adapter), or
your vehicle’s cigarette-lighter socket
(with an optional adapter) so you can
make music almost anywhere.
