[CM] Loop bug?

[Rick Taube]

that’s wierd, it sure seems like a  bug — ill take a look at it.

in  the meantime someting like this should work

(let (( chord (transpose (pick '(0 3 7)
                                   '(0 4 7)
                                   '(0 3 7 10)
                                   '(0 4 7 10)
                                   '(0 4 7 11))
                             (between 48 80))))
  (loop for foo in chord …)
