Vangelis - Chariots Of Fire [Live] stereo

YouTube via NorskTorsk. Anyone know what the units are on top of the piano?

Update via Siebe in the comments: "The boxes on top of the piano are probably Zyklus sequencers. There's almost no info on the internet." See the Zyklus label below. The ones previously posted do look a bit different. Maybe a different model or custom made for Vangelis?

Update: riddle solved
