Wasn't Xkey a product from CME?

Originally developed by CME, ESI and Artesia Pro have teamed up to continue the support and the development for the Xkey product line. This means that ESI is responsible for the product development and the full technical support for all CME Xkey models as well as our new X series products such as Xkey 25, Xkey Air 25, Xkey 37, Xkey Air 37, Xjam and Xsynth.

CME remains an independent manufacturer of new and innovative products.
