I have designed the UTEP Digital Keyboard Lab (DKL) in 2006, and since it has been a model worldwide. It was upgraded in the Spring of 2019 at a cost of $124,000. The whopping 2007 AV features still in place but were all changed to digital: 3 cameras (top keyboard, side keyboard and pedals), touch screen to control all AV aspects of the lab, wireless headsets, excellent audio system, and much more. Colleagues from all over the world regularly consult me about the DKL's equipment and features.
