I saw this item on ebay and was very interested but am wondering how you play it. It says that it is an arranger but there are no keys to press so how do you change chords and play the onboard sounds. I don't want to sound like an idiot but I own a keyboard and don't want to trade it in for an x1 but would love to have the best of both worlds with the x4 and my Kn5000. Unfortunately I don't understand how one would play this instrument.
any info would be appreciated.

Thanx
