States that Keith used the piano in his live setup

Sound on Sound lists Keith's gear in this article, which includes a Hohner Clavinet D6 Classic keyboard with real strings.

This Sound On Sound article states: "The huge cost of the Fairlight CMI did not put the rich and famous off. Peter Vogel brought an early CMI to the UK in person, and one of the first people to get one was Peter Gabriel. Once UK distributor Syco Systems had been set up, the client list started to grow. John Paul Jones (Led Zeppelin) bought the first as a replacement for his Mellotron. He was soon followed by Kate Bush, Thomas Dolby, Geoff Downes, Queen, Keith Emerson, Alan Parsons, Stuart Copeland, JJ of Art of Noise, Trevor Horn and Frankie Goes To Hollywood, and many others."

I worked with Kurzweil in the 80s and owned a K250 Expander and MidiBoard. You can clearly see the K250 on the left side of Keith's 1986 keyboard rig. You can also clearly hear the very distinctive K250 CHOIR patch from Sound Block A all over "The Score" - both live and on the studio recording. You can hear the K250 percussion (claps, snaps and shakers) all over Touch & Go as well. The "Endless Glissando" patch as well as the K250 choir and strings are all over "Mars, The Bringer of War."

The MidiBoard is the large 88 note controller placed on top of his GX-1. See the video.

Again....I worked for Kurzweil and owned all of these instruments. Keith was endorsed by Kurzweil Music Systems in the 80s, with a K250 and a Midiboard. Both were used on the EL Powell album and can be seen in music videos and on live concert footage. I also got to see Keith's rig in person. Keith triggered sounds from a Yamaha TX-816 and an Overheim Matrix 12 with his MidiBoard. That's where the big brass lead for "The Score" and "Touch and Go" came from. In later years, he switched to cheaper, thinner synths like the Korg O1W and an Alesis. Neither ever captured the magic of the original FM/OB analog layers. Or the GX-1 for that matter.
