Use the following example to layer two tones (dual play) across the entire keyboard:
1. While holding down the Piano button, press the Strings button so that both buttons are lit.
NOTE: You will hear both the piano and the strings playing together.
2. To change the piano sound (the "left" tone button), press the - / + buttons to select a different piano tone in the piano tone group.
3. To change the string sound (the "right" tone button), hold down the STRINGS button and use the - / + buttons to select a different string tone.
4. To exit dual play, press any single Tone button.
NOTE: Dual play is not available if Split Play or Twin Piano are turned on.
