Also when looking at an Audio interface check what freebies you get with it and the restrictions on the freebies.

For example, I looked for a new interface to replace one that was starting to play up. I cut it to two the Presonus 24C and a Focusrite both of which did just what I needed (even more). I was excited by the Presonus as it included Studio One Artist (not that I needed it) so that swayed the decision only to find the disappointing product limitations. Had I gone with the Focusrite there were other goodies and better options later.

Using an Audio interface will mean running via the computer even if you are only using the piano. The computer powers the Audio interface. But it will allow you to use both at the same time.

Just some of my experiences.
