Window menu > ScoreManager > Instrument List

In the column Name, for the chord staff, click the small “triangle” > to expand the view of the chord staff.

You can set the Chords to a different playback channel, with a different playback instrument.

So I must create a chord staff first?  Seems like a lot of unnecessary additional work.  Either that or I don't know how to make visible a chord staff.  Here's a picture of my ScoreManaager window.  (And thanks for your assistance)

Chord symbols are always attached to a staff.

In your screen shot there are four staves.

If your document has chord symbols, then the chord symbols are attached to one the the four staves shown in the Instrument List.

I do not know, to which staff your chord symbols are attached.

In this example let us say that the chord symbols are attached to the ‘Rick’ staff.

In the ‘Name’ column, for the ‘Rick’ staff, click the small “triangle” > to expand the view of the ‘Rick’ staff.

(This “triangle”: > Rick)

You can set the Chords to a different playback channel, with a different playback instrument.

Got it.  Thanks so much.  More learned every day thanks to good people like you.
