I first create a chord track. I then create an instrument track (with a HALion instrument, an electric piano). Under the Inspector of that instrument track I select Chords > Single Voice > Bass. The Voicings are set to “Piano”.
PROBLEM: the instrument track plays the whole chords, not just the bass note. Same if I select another voice (soprano, alt, tenor etc.). Selecting “Root Notes” instead of “Single Voice” doesn’t have any effect either. The whole chord is still being played.
