I have a Roland Piano FP30X which has dedicated line out. While it has the feature such as recording to a flash drive, I am looking to understand how to record through an interface, which for my case is Focusrtie Clarett 4Pre.

1. What kind of cables do I need? Do I need TS/TRS cables?
2. Which part of the output from the piano do I connect to to the interface? And which input is for the Clarett?
3. How better would it be to record through the piano's line out than through the headphone jack?
