Free bass system confusion

[Niknak]

I’m going to purchase a Roland FR-4xb soon using c-system and want to learn the free bass so I downloaded the user manual to get started. I notice the manual gives you 5 free bass options.

1. Minor 3rds
2. Bajan (assuming Bayan)
3. Fifth
4. N. Europe
5. Finish

I know I want the notes to go from low (chin) to high so it’s not Bayan. Not sure which system to use.
