Hello Spalding
Had another look at the video and while there may be a programmed drum style about the middle of the piece, I cannot see or hear any indication of a Midi file being used.

If you fancy a listen to the top artists, then book a week’s holiday in May and go to the Blackpool keyboard festival, where you will see a lot of top performers http://www.keyboard-cavalcade.co.uk/festival.htm (Including this year Franz Lambert, who also has a DVD that I can highly recommend, here’s a demo http://download.yousendit.com/05D0852068E3D2E0)

General
As to the performance, it is quite common for players from Asia, and has been for many years, (If you go to the Blackpool keyboard festival and watch the electone competition you will find quite a few Chinese now showing up) however apart from the contests, 99.9% of the players are not heard from again in the West, because while technically proficient, they are not entertainers.
As a matter of fact in the last 30 years while performances like these have been common, (They are all taught through the Yamaha Music School) there are only 2 artists from Asia whose names are still around, these being Chiho Sunamoto and Max Takano.
