Jim, I just got a cd from Kellyco that is for ear training for the Excalibur It was twenty bucks. But an awesome CD to get a head start on the tones for the Excalibur. Here's the thing, by listening to the small subtle differences in the notes you can tell cash from trash, pull tab from gold, etc. There is no reason in the world why such a CD couldn't be made for any other machine. The only requirement would be a sound room where they record musicians. Can't figure why someone hasn't done it yet.![Shrug :shrug: :shrug:](https://www.findmall.com/styles/smileys/shrug.gif)
