Arpeggio spanning 2 (or more) staves - proper playback

Hi, everyone.

I am slowly learning MuseScore, and wanted to write a single arpeggio that spans the grand staff. Easy to add the symbol, but MuseScore won't play it back correctly.

4 years ago, "Mike320" posted a workaround. I slightly modified it (because I couldn't quite get it to work using his clever method).

I have attached my explanation in the attached .mscz file.

If some of the experts on this site would take a look at it, that would be great.

• Is there an easier way to do this?
• Does MuseScore have any plans to make a multi-stave arpeggio/glissando playback correctly?

Thanks for any suggestions you have. If you can offer any suggestions/corrections/simplifications on this process, I will modify this sheet and repost it. Perhaps it will help other beginners who want to do the same thing.

Thanks!
David
