Hi c_major,
Yes, that is what I want to be able to do and I seem to have found a way to do it!
Open a new untitled score.and before you do anything else, you open the 'score' tab and click on the 'append bar' three times and three vertical bars appear spaced evenly along the stave. Once the notes are placed between the vertical bar lines then, by highlighting between the vertical bar sections and pressing 'auto-format', a creditable attempt is made at evenly spacing the notes, especially if they are all crotchets, minims or semi quavers etc. Some adjustment is needed if there is a mixture of notes.
It would have been good however, if more than three bar lines, say four or five, were available to use and then it wouldn't look so gappy with slow music notation.
Regards
