      This is for generating some jazz licks in the style of the LINEAR EXPRESSIONS, by jazz guitarist PAT MARTINO.
      The rhythm slots of the example contain the same 16th value, but it can be worked out as Rhythmic Cells. I was testing straight 16th lines.

      here are the two functions i use daily in my workflow.
      The first gen-pitch-line can be used as this but is also required for the second function svoice1.
      svoice1 is a generic omn generator i find useful for my work.

      is there another way to code such a function/idea?
      this is (at the moment) a "theoretically function"... no concret use - l'art pour l'art :-)
      thanx for smarter LISP-code-IDEAS!
