Problem with iPhone 5 and iRig Keys
According to the documentation at the iRig Keys pages, you should be able to use Apple's Lightning to 30 pin adapter. What sometimes happens with regular connector cables that develop a break, or for some third party adapters, is that there's a voltage drop that prevents fully functional use. That can result in either a warning message like "This accessory is not supported", or discovering that the i adapter will work for some purposes, such as charging, but not others, such as the full music interface. With other connectors, such as the 30 pin to VGA out connectors that let you project presentation apps or videos to standard displays, the power requirements can change according to the device. (The VGA connectors that were designed for the second generation iPads will not work for the 3rd generation models that use more power, although the newer VGA to 30 pin adapters will work for both second and third generation iPads.)
It's always best to check the manufacturer's specs. I'll paste in an excerpt from the iRig Keys support web page, and give you the source URL. According to this document, using the Apple Lightning to 30 pin connector with the iRig Keys will work with an iPhone 5. If you purchase the Apple product, and it did not work, you should try to get a refund on your purchase. You might even show the displayed article along with the adapter to your local Apple Store, where you should also be able to purchase the adapter. If this is a third party adapter from another manufacturer, that may be the source of your problem. (Note: link is to product in U.S. Apple Store.)
