I had a dx7. I will vouch for it being difficult to program decent sounds for. Despite having a map of how the 6 oscillators interacted on top of the Keyboard. See photo: https://mn2s.com/news/features/brief-history-yamaha-dx7/ https://mn2s.com/news/features/brief-history-yamaha-dx7/ It didn’t help that in the 90s when I had that keyboard they’re weren’t many online sources of info about it.. The dx7 was neat but couldn’t make very realistic instrument sounds. Very popular though.
