shin1ro,

If what you mean by the "1" chords is that you just want the bass note of each one, there's a less cluttered way to indicate it.

For example, to hear just an "A" in the bass, hit the vertical oblong shape to the right of the fermata and then type "A." When you go out of Edit mode the shape disappears and you're left with "/A."

Cheers,
Jer
