Midi Setup (Roland Digitial Piano with Rubix22 interface)

Dorico records into only 1 staff, not the grand piano staff (treble & bass) with my Rubix 22 (interface into Roland digital piano). The Rubix 22 has 2 Midi inputs and 2 Midi outputs connected to the Roland, so I don’t know what is wrong. Is it just a Dorico setting?
Advice?

Welcome to the forum, @Rick_L. It should hopefully be as simple as selecting the bar rest in both the right- and left-hand staves before you start recording, and then Dorico will record in both.

Thanks for the response. That didn’t work, but I edited the instrument (right panel) in play mode, and made sure that Dorico was selected, but 2 midi inputs and 1 midi output, and then it worked!
