Is it a piano, filter, or something else?
 

Hello there ^^
I have been wondering what exactly makes that piano sound special in that YouTube video:




I mean... It is like an echo, but I can not find it anywhere on internet while typing "Echo piano" or something simmiliar.

Maybe You could help me?

Thanks in advance ;)
