Scale Assistant muting other tracks

When I use scale assistant on any track, it will then mute all my other tracks. What I am trying to do is add a melody line to be in key with chords on another track. When I enable that I cannot here the other tracks!Any ideas would be appreciated !

On your screenshot “Solo” in the key editor is active, thus muting all other channels.

Thanks, is its possible to use the Scale Assistant on a track, and at the same time hear the other tracks in the project. I want to play I scale and hear the entire mix. - Thoughts?
