It's possible to do the same with a Tyros2/3 or even an S910 if you have a lower keyboard, like a Yamaha NP-30 and a decent set of MIDI pedals (at least more than an octave).

I grew up playing Electones (last one was an HX-1), but I prefer having the single keyboard...auto-accompaniment bass lines are so much better than years ago, and you can program your own.

The player featured has obviously spent a lot of time on the instrument.
