I am trying to add 1 note at the end 4/4 bar
i have figured out how to do it at the beginning with the dots after the chord any suggestions would be appreciated

Welcome to the forums.
In general, the notes are actually created by BiaB from the Chords that you enter.
When you mention "at the end 4/4 bar" do you mean on the 4th beat or after the 4th beat?
You can possibly add one note if you use MIDI and use the Soloist or Melodist track.

On the forth beat

Bob,

Are you meaning that you would like to enter a chord on beat 4 (rather than a note)? Asking for a note seems to indicate that you are talking about melodic notation

Regards,
Noel

To enter a chord on the 4th beat, precede the chord with a comma (,) character e.g. ",G"
as follows:

Thanks it works
Bob
