How To Do This In Sebelius?

In piano notation, how to put the bar in the middle with a stem going to the treble clef and a stem going to the bass clef? see pic.

you write all notes in same staff, then you select the notes and use Ctrl+Shift+Down to move them to the lower staff, Ctrl+Shift+Up will move them to upper staff, it's called crossing staff.

Also you may need to hide rest on the other staff because crossing staff notes are visible in the other staff but they count as they are still in the same than the others.

Thanks, that did the trick. I didn't have problems with rests. The bars came out completely horizontal. is there a place where I can make these slanted? If not, it's OK.

not sure what you mean but try to drag the part you want to move.

Actually I did run into problems with the split staff notes. I created a separate instrument staff to experiment. When it looked the way I wanted I pasted it back into the original instrument. But it didn't paste properly, it put everything back to one staff. Further, it would not let me correct it by cmd-sft-arrow. :veryunsure:

Only now I realized you have problems because you're using "Sebelius" :D

YOu shouldn't have problems, now that I think about it, I have never done it in staves others than Piano or Harp, that sibelius somehow understand as 1, but never crossing Flute to Oboe for instance, try again in a double staff piano instrument you created by add instrument.
