Yes, it's just the "onboard" arpeggiator.
The sound is proudly made by Mr. Nick Rhodes with a genuine Jupiter 8.
I've bought just today this software and, as I'm a GREAT fan of Duran Duran, I'll try to do my best to find the exact sound that mr. Rhodes used on Hungry Like The Wolf.
As soon as done, I'll post it in the Presets section.
All Duran Duran fans are invited to do the same with their presets!!
