They both seem to be the 'same' product, but i am worried that if i buy an ebay version, and it dosent work, I may end up buying a UX16 aswell and spending around £50. Has anyone had any experience with these kinds of MIDI to USB converters??? They both claim to do the same thing, but i dont know which one to buy.
