hello i try to make this work any idea ?

(gen-filter-change 
 (permute '(gs4 e4 d4 c4 c4 a4 fs4)) 
 '(1/16 1/2 1/4 1/4)
 '(pp ff mf))

Thanks,

Patrick

Using PERMUTE function here, is not what you should do.

Seven elements to permute will produce overload or will take looooong time.

So the solution is to place it before the function  as a variable isn't it  ?

You could do something like that:

(gen-filter-change
 (rnd-sample 24 '(gs4 e4 d4 c4 c4 a4 fs4))
 '(1/16 1/2 1/4 1/4) 
 '(pp ff mf))

or

(gen-loop 12 (gen-filter-change
              (rnd-order '(gs4 e4 d4 c4 c4 a4 fs4))
              '(1/16 1/2 1/4 1/4) 
              '(pp ff mf)))

etc...
