Hi, I think I figured that out by locating an ex. in test.scm. (partials->polynomial '(1 1 3 2 6 1)) ;(-1.0 -5.0 18.0 8.0 -48.0 0.0 32.0)
instead of using the resulting eval of (partials->polynomial) as input to coeffs: (set! gen1 (make-polyshape 440.0 :coeffs '(-1.0 -5.0 18.0 8.0 -48.0 0.0 32.0)))) It rather seems to want the whole function call: (set! gen1 (make-polyshape 440.0 :coeffs (partials->polynomial '(1 1)))) or (set! gen1 (make-polyshape 440.0 :coeffs (partials->polynomial '(1 1 3 2 6 1)))) nice. Thanks, Jim
