How do I join beams across piano staves?

How do I get the joined beams for LH/RH phrasing?

Start off with all the notes on one stave. Then select the notes you want to move up a stave and hit N (for North), or select all the notes you want to move down a stave and hit M.

I tried that and it separated all of the beams.

Were they beamed together before you moved some of the notes to the other stave? If so, I’d hazard a guess you used Alt-M/N, not M/N, which is a different function. If not, you’ll need to beam them together either by altering the time signature or the Notation Options > Beam Grouping, or by right-clicking > Beaming > Beam Together.


Ah yes, my mistake. I was using alt+M.
