YIKES!
I just ordered the same one to go with a Yamaha EZ200 MIDI keyboard I just ordered from amazon.
I know some USB/MIDI cables are advertised for $45 or $50 so thought I'd try this one and save a few bucks.
Maybe not such a good idea.

Will see what the experts here recommend.

Are you using a PC or a Mac?
I'm using Windows XP service pack 3 on a Dell desktop.
May make a difference?

Will let you know if mine works when they arrive probably next week.
