When entering chords and qualities in the chord-entry field, if you type a "W" (instead of a note letter) a pink splotch will be entered in the editor which results in a chord name not being displayed (invisible) on the chart and a chord not played by the player.

You can then add a slash (/) and the bass note you want the player to sound.

W/Bb = /Bb You can use this to pedal a note or (in a limited way) define a bass-line or bass pick-up notes.

Scroll to "bass notes" in this post:
