It appears to happen because the 2.19 version seems to associate the MIDI output per-voice instead of per-staff. As a (ugly) workaround I used this (setting and soon after unsetting a voice): LilyPond Score

Please, check this snippet ( from http://lsr.di.unimi.it/LSR/Item?id=357 ), with Lilybin http://lilybin.com/eg700v/1 The same error doesn't occur if you compile the snippet with 2.18 version. 1) Is there a workaround for that?2) Is there a particular version of the 2.19 branch that doesn't cause the bug? ThanksPaolo
