I had gotten myself into a quandry which I simplified in the following example. (see attachment)
In fig1, the goal is to remove the 5/4 -> 4/4 change by removing the quarter rest and having everything close up.
In my first try, (fig2), I got that strange 1 beat measure. Ultimately removing the subsequent 4/4 fixed it, but it took me a few tries (ctrl-z is my favorite function) to figure that out (I kept trying to remove the bar, forgot to turn off the insert mode, removed the second 4/4 first, etc… ). Also understand this example is a contrived simplification; in the original, there was tons of music on many voices on both staves following this point which got very messed up.
I also tried (fig3), and was puzzled where the extra rests came from since, in this example, I left ins mode on, so I assumed the spacing should close up.
I’m just passing this back to the developers to examine these results and suggest what is the recommended way to do this kind of editing
