Umm, do you not consider 11/9 an 11-limit consonance? (I know we have periodic wars on this subject on the list, at least when Brian is contributing.) If you do, then 11/6 and 18/11 also fit your criteria, which makes it a 24-note scale instead of 22. --pH http://library.wustl.edu/~manynote O /\ "Churchill?
