Playing single notes, for bass lines and riffs

Is there a way to play single notes with Scaler 2? It seems beyond chords I want to play root notes to chords and play in a key with white keys only. I actually assumed this would be trivial to do with scaler but not seeing how. Anyone know?

Press Keyslock and select Chord Notes or Chord Extensions. In the settings menu select MUTED to hear the single notes only.
