Well, if you move "Staff_performer" to put each voice on a separate channel,
then I think we *want* the first voice to ignore dynamics in the second.

We would want this when we put different instruments sounds on the same staff, 
as in http://lsr.dsi.unimi.it/LSR/Item?id=766 which is the usual reason for 
moving Staff_performer.

Probably you first tried it using the defaults, in which case I also see a bug, 
which probably appeared when dynamics were recently re-implemented as
note-on-velocity.

% MIDI dynamics take effect one-note-late, if they are in a separate voice
% We expect each measure to sound the same

  \new Staff  <<

      { s1 | s2\ffff s2\ppp }
    >>
  \layout {}
  \midi {}
}
