GM-800: How can I add different TONES to specific strings?

The GM-800 can assign TONES in a given SCENE to individual strings.
Useful if you want to play a bass synth part on your lower strings, and perhaps a high brass tone for the higher strings. 

1. Select the TONE in your SCENE you wish to edit, by selecting the corresponding number.
2. Use the SELECT knob to navigate to STRING.
3. Use KNOB 1 to toggle S.MUTE ON or OFF.
   By default, this is set to OFF for each string so every string will sound the tone.
4. Use the PAGE [>] right button to navigate to each string, toggling the S.MUTE ON or OFF accordingly.
5. Press the WRITE button
6. Use KNOB 1 to WRITE the SCENE (or EXCHANGE to move it to a different location).
7. Repeat these steps for each TONE you wish to edit.
