I didn't make any changes to MIDI, myself, but I have been watching, and the 
code controlling this behavior has not changed.
Added tracker item <http://code.google.com/p/lilypond/issues/detail?id=1647>.  
I intend to check the code soon and comment there on whether it would be easy to fix.

In October, Javier and I discussed a workaround 
(http://lists.gnu.org/archive/html/lilypond-user/2010-10/msg00520.html) which 
works fine for stable version 2.12.

The recent changes to MIDI require more workaround for version 2.13.55 and 
later:

 \midi{
  \context {
    \Score
    % assign one MIDI channel to each Staff_performer
    midiChannelMapping = #'voice
  }
 % create a different Staff_performer (sic) for each *Voice*
 % so that you get one MIDI channel per Voice
  \context {
    \Staff
    \remove "Staff_performer"
  }
  \context {
    \Voice
    \consists "Staff_performer"
  }
