I guess this is more a history lesson than anything else, but my PSR-8000 operates as UD desires in fingered 1 and fingered 2 mode. c-eb triggers a minor third. c-bb triggers a seventh. Which 7th you ask? Depends on the preceding chord. If it follows Cmaj, it plays C7, if it follows Cmin, it plays Cmin7.

Have you naysayers checked all the fingering modes on the these keyboards. I would be quite surprised if the Tyros couldn't recognize 2-finger chords properly in at least one of its modes.
