      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.

      Dear Friends,
      1) How to convert a given length series in a binary series ? For example:
      ((1/16 -3/16 1/16 -1/8 1/16 -1/4)) with 1/16 as a base could be transformed in binary like:
      (1 0 0 0 1 0 0 1 0 0 0 0)
      2) How to convert a length  3/16 in 1/16 -1/16 -1/16, i.e. a kind of length conversion
       based on quantize.
      3/16 could be converted in
      1/16 -1/16 -1/16
      1/32 -1/32 -1/32 -1/32 -1/32 -1/32
      depending on the value regarded as the reference (1/16 in the first case or 1/32 in the second)
      Thanks !
      Code example
      (setf ccpa1 (omn :length (length-staccato 1/16 (time-point-system (pitch-rotate 0 (pcs '3-11b :pitch))'s :start 0)))) ;EXTRA FUNCTION NEEDED ;;;LENGTH-LEGATO (by ANDRE MEIER) (defun length-staccato (n alist) (let ((newlengths) (new-omn (omn-merge-ties (flatten alist))) (time-sign (get-time-signature alist))) (progn (setf newlengths (loop for i in (omn :length new-omn) when (> i 0) append (if (= n i) (list i) (list n (* -1 (abs (- i n))))) else collect i)) (if (omn-formp alist) (omn-to-time-signature (make-omn :length newlengths :pitch (omn :pitch new-omn) :velocity (omn :velocity new-omn) :articulation (omn :articulation new-omn)) time-sign) newlengths))))

      hi all
      i need a little lisp-help...
      i want to split things like this perhaps 'an3 into '(a n 3)
      is there a way?
