I can't believe I am the first person to report this. Yet the output for PMX 2.73 and PMX 2.82 looks the same. The non-beamed octave chords are perfect, the beamed ones have their stem length wrong and therefore the beam position too.
I need this for something I am typesetting right now. i don't need a fix, a workaround will do. ~~~~ 2 -1 2 3 4 3 4 0.00000 -2 1 1 20 0 60 ./ Tc PMX 2.73 Tt Beam Error Arb w60m g83 zg- a8+ za- b4+ zb- e4s ze- / b84e a8 g4 g4e // d2+ zd- c4+ zc- / ~~~~ The attached .pmx file contains the same PMX code. -- Dirk
