I own a Yamaha PSR E403. This series is a lower end class of synthetizer/arranger keyboards targeted towards novice players. Mine also has an identical UI to the one presented here. I wonder if the hack would work on it as well, being a similar model.
My better keyboard is a Yamaha CP88 which is a lot more modern and has updatable firmware. I poked a bit with the update package using binwalk and as far as I could tell it’s not encrypted, and runs some version of QNX. My hacking skills aren’t as good, but I wonder if that one has similar exploits.
