Lilypond is correctly engraving this score in .pdf, which has some sections of single-staff polyphony. However, the MIDI playback on my PC plays one voice only. I'm ignorant to where the problem is. Is my lilypond syntax incorrect? Is my PC (Win7/WMP10) not able to play multivoice MIDI? Is lilypond not adding the 2nd voice to the MIDI file? Thank You, Javier
