ARP Quadra

The ARP Quadra was one of Tony Banks' keyboards.

He began using the Quadra around the time of the Duke album, initially alongside an ARP 2600. This was his go-to synthesizer for lead lines - processing the sounds with a fuzz box, as heard on songs like "Abacab". He had also experimented with triggering the ARP Quadra with a Linn LM-1 drum machine on the Fugitive soundtrack and "Mama" from the Genesis album, to generate a rhythmic pulse.

Live, a Korg WT-12 Chromatic Tuner was used to keep the Quadra oscillators in tune.

By 1986, the ARP Quadra was fitted with MIDI for the Invisible Touch tour.
