“When we first signed to Virgin we had a little bit of money in the bank to build a small studio and to buy some new instruments, and that was just the time when the Jupiter-4 came out.
“I remember saying to Bob Last, who was our manager at the time, ‘This is my dream machine; there will never be another synth that’s so significant in my life as this’.
“Of course, you had the ease of use of all the sliders for the ADSRs and filters, but mainly it was the arpeggiation that was so beautiful and amazing. We take all that for granted these days, but it was still quite an unusual thing in those days. That’s what enabled us to create loads of shimmering textures.
“There’s a [Human League] track called WXJL Tonight, on Travelogue, which is basically major sixth chords jumping around all over the place on the fastest arpeggiation setting possible, with quite a long release. In other words, the arpeggiation blended into these amazing shimmering sounds, which I personally had never heard anything like before.
