Ahh, OK.  Now I understand.

I think that the arguments to make-scale should not have implicit steps
(which they currently do).  They should be lists instead of pairs (or else
they should be (step . alteration) pairs.  And the value of each number in
the list should correspond to the weights in the values list.

((0 0 0) (1 0 0) (2 0 0) (3 -1 0) (4 -1 0) (5 -1 0) (6 -1 0) (6 0 0))

(1 1/2 1/4)

That way there is a one-to-one correspondence between the pitch declarations
and the weightings.

As long as we're adjusting things, I think we ought to be consistent.

Thanks,

Carl
