1&2 are the same question. You specify the binary log (actually its negative) of the duration rather than the duration as a fraction. The answer to 3 and other is that Lilypond is incapable of forming the right chord. You could try using simultaneous notes (stack the three in << >>) but it's rather likely that the stems will not be combined properly and/or you'll get a note column collision warning. This solution would have the advantage of producing correct Midi. What you do instead is using whiteout in order to change the notehead without Lilypond knowing what you do. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
