Andrew Farriss

As seen in this Video (at 1:10) he used a Korg T3 at Wembley Stadium 1991

A quote from Andrew Farriss, from Mix Online article:

“I used a Roland 707 drum machine to program the groove for what became ‘Need You Tonight,’” he says. “What’s on the record is pretty much exactly what I put into the drum machine. What I also tracked from memory was the guitar riff, the bass part—which I played on a keyboard bass—and there was a rhythm guitar part that never actually ended up on the record. There was something about it that sounded right in my head, so that’s why I made the cassette recording of it: ‘I don’t know what this thing is, but there’s something in it.’”

“We also had the 707 [drum machine beat] and an Emulator 2 sample of a bass sound I made up from a MIDI keyboard. The guitars were Fenders through some old Marshall amps. Jon would have had a Pearl [drum] kit of some sort and [Remo] Roto Toms. He did some cymbals, toms and fill stuff across the drum machine, as well. Garry added a bass part with a Fender Precision bass, and some of the guitar was overdubbed. It was important that the guitar work have the push-pull of people really playing—trying to get that aggression, that edginess, to come out.”

At the 3-minute and 19-second mark of the video titled "INXS Living Part 1," uploaded by maxsq1989, Andrew Farriss is visually confirmed using a Sequential Circuits Prophet 5 Rev 3 during a live performance with INXS. This footage is from the "Rocking The Royals" concert in Melbourne, 1985.
