Midi in, out and thru question

Hello

I would lile to ask if midi files on my computer can be played on the clp-120 (model 2006) using the midi in. I know I can use the Clavinova clp-120 keyboard to record and play tunes on the laptop using the midi out. Is there any specialised software? Also what scenarios would you use the midi thru on the clp-120.

Thanks

Jim
