Can I listen to only one voice?

Total newbie here. Thought I might try to use musescore to learn how to sing parts in a song. I have the song as a MusicXML with 4 part harmony. It is made with 4 voices, so the different parts light up in different colors.

But, is there a way I can play through the song and only listen to one of the voices? Tried the Mixer, which does have a Solo and Mute button, but those seem to turn off everything rather than just one voice.

Any ideas?
