Why doesn't the Light Guide match the keys I'm playing on my Yamaha Portatone EZ-150 Electronic Keyboard?
When auto accompaniment is on, the Light Guide shows the specific notes of the chords you play in the auto accompaniment area of the keyboard. If you play a single finger chord, or an inversion of a chord, the corresponding chord will be appropriately shown — even if the lighting keys do not exactly match the pressed keys.
