Sorry one again to answer so late.

copy-out :

- An instrument 'instru has a section of his music (for ex from bar 11 
to bar 19) that comes back several times.

  (copy-out 'instru 11 19 40 60 80)

=> the section 11-19 is copied to bar 40 then to bar 60 then to bar 80.

- If all instrument of your score have their section 11-19 repeated :

   all = #'(fl1 fl2 oboe1 oboe2 cl1 cl2 ......)

   (copy-out all 11 19 40 60 80)

=> the section 11-19 of each instrument is copied to bar 40, 60, 80

- If a piece of music has a section repeated but transposed to a fifth 
higher for example, you have to use (copy-out-with-func func) instead :

  (let ((5th (set-transp 0 4 0))) ; 4 notes above = a fith
    ((copy-out-with-func 5th) all 1 20 80))

=> the section 1-20 of each instrument is copied to bar 80 but 
transposed a fifth higher.

Hope that helps.
