In all the examples, the score has the instruments readily defined by the programmer:

(def-score 
    (:score-prop score-val ...)
    (instrument-1 
        :instrument-prop instrument-val
        ...)
    (instrument-2
        :instrument-prop instrument-val
        ...)
)

 

What I have been wondering is can I dynamically create these instruments, allowing for proper reference in :layout afterwards, etc.

For example, if I wanted 10 instruments:  

(defun my-generate-instrument ...) ;; something

(def-score 
    (:score-prop score-val ...)
    (loop 
        for i from 1 to 10
        collect (my-generate-instrument i)))

 

Any tips for an scenario like this one? 

Possibly in version 1.2
Achim Bornhoeft as well has suggest the same thing.
