>A Casio CZ-101 can be seen on one picture of their live performance, positioned on the drum stands in front of Michael Sandison. The Casio CZ-101 is visibly linked to other equipment solely through a MIDI cable, indicating its probable role as a MIDI keyboard within this live setup. Strikingly, the synth's audio output remains unutilized during the performance.
