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.

Looks yours is a 6 years older version of the same thing, so I think there’s a decent chance the same thing will work. The tools are on the author’s github: https://github.com/portasynthinca3/swl01u/blob/bf50f89b1d28701791a4866ef97944513e8c6a1c/shell.py
