32-Note Polyphonic Sound - lets you play
and hear up to 32 notes at the same time, so you
can play or create almost any type of music.
Large Display - shows you the notes and
chords as you play them, along with the current

makes it easy to read, even in dim light.
This Owner's Manual explains how to use this electronic keyboard. It does not teach music.
The keyboard conforms to most, but not all, General MIDI specifications. Because of this, you might
experience some incompatibility when using the keyboard with another General MIDI device. For
more information, see "Using MIDI" on Page 19. Your keyboard also includes a MIDI (Musical
Instrument Digital Interface) feature, which lets you connect it to other MIDI-equipped musical
instruments or devices - even your personal computer.

248 Tones - uses technology usually found only on
professional equipment to allow you to set your
keyboard to sound like anything from a harpsichord to a
honky-tonk piano. 100 of these tones have
corresponding advanced tones, created by
programming in digital signal processor (DSP) effects
and other settings. You can even create up to 32 of
your own tones with the custom tone synthesizer
feature (see "Using the Tone Synthesizer" on Page 13).
Auto Accompaniment - lets you automatically play a
preset harmonic pattern to match the selected auto-
rhythm (see "Using Auto Accompaniment" on Page 10).
