[CM] clm delay offset for tap?

[andersvi at notam02.no]

Hi Bill, others.

I'm confused about (positive) offset argument to tap.

Negative offsets yields perhaps expected results, but positive offsets
starts pulling values from what seems an odd offset into the line.

(set! (*s7* 'print-length) 20)

(define d1 (make-delay 10))

(do ((i 0 (+ 1 i)))
    ((= i 10))
  (delay d1 i))

(mus-data d1)
=> (float-vector 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0)

(tap d1)
=> 0.0
(tap d1 1)
=> 5.0
(tap d1 -1)
=> 1.0

(map (lambda (i) (tap d1 i)) '(0 1 2 3 4 5 6 7 8 9))
=> (0.0 5.0 4.0 3.0 2.0 1.0 0.0 9.0 8.0 7.0)

(map (lambda (i) (tap d1 i)) '(-0 -1 -2 -3 -4 -5 -6 -7 -8 -9))
=> (0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0)

Thanks for all help and guidance.
