Dear lilypond-users, how can I change the automatic beams for the triplets in this example? I would like to beam the triplets in groups of three and I would like to do it automatically. Here the example: \version "2.11.7"
{ \time 2/2 f'' 4 \times 2/3 { a'' 8 g'' f'' } \times 2/3 { e'' d'' c'' } \times 2/3 { b' d'' b' } }
