lengthening bar

With AND without insert mode active, changing the bar from a 3/4 to a 4/4 is shifting the subsequent music. How do I avoid that?

Before changing the time signature, add an explicit 3/4 time signature to the following measure.

After you change the previous bar to 4/4, you’ll need to add a missing beat. Shift-B, 1q.

Time signature changes are designed to rebar the music, that’s why it’s happening.

Thanks for the clear explanation. It worked.

If insert mode is on when you do the 4/4 the extra beat is added automatically…
