Casio midi cake 496 keyboard (Jamaica new york)

In ok. Condition. The lower key on the left don't work unless u play a chord.. which is odd...but hey... that's why I'm posting this for free. Mayb somebody is learning n wants something to practice on. This would be great. It uses 6 AA Batteries or a plug. Which I don't have.
Please pick this up ASAP. Thanx
N give me a day n time. If the ad is up IT'S still AVAILABLE
