@jk If I had to make a guess, I'd say that arpeggiators were an "advanced" synthesizer technology in a critical window of time when a great deal of the educational content consumed by Gen X and millennials was being produced, so it made sense for that educational content to use arpeggiators if they wanted to sound sciencey, and so now we've all got that association. But this theory will make less and less sense as millennials age out. Do Zoomers/Alphas have this association? If so, why?
