My lower voice is always set on Manual Bass, but I don't remember how I stored it there! I prefer using the lower sound to the Korg "Manual Bass" because it's always the SAME instrument. The Korg choice is the bass that is a assigned to the selected style, and sometimes they don't play as well LIVE, as they do in a programmed setting. I like having the same bass player on the job all night long .... just like real life. The arranger styles simulate if he/she brought a different instrument or played a different style sometimes.
Either way - glad you found what you wanted!
Everyone, and everything I listen to is my teacher. Every instrument, every voice, every sound in nature ... they are all my private tutor ... 24/7 for free.
