I have an SD1 on the floor in my store and the intro 1 works fine on Wolle Beat. The interesting thing is the intro is much like variation 1 except that when I play a C major chord, for example, it is a 4 measure intro with an alernation of the chord you hit plus the fourth above ( if I hit C it then plays 1 measure of C followed by one measure of F followed by one measure of c and then the last measure of F with a fill going into version 1. When it goes into variation A it is the same as the first measure of the intro . I hope I'm not getting you all too confused here!
