1. Under ZONE SWITCH, press the four part buttons so that UPPER 1 is lit and the others are not lit.
2. Use the TONE SELECT buttons to choose a tone for the first part of the layer.
3. Press UPPER 2 so it is lit.
4. Use the TONE SELECT buttons to choose a tone for the second part of the layer.
NOTE: You can repeat these steps using LOWER 1 and LOWER 2 to add two additional layers for a total of four tones playing simultaneously. Use the volume sliders under the ZONE SWITCH buttons to adjust the relative volumes of the layer tones.
