Probably you know this, but LilyPond will accept a change
 \set Staff.midiInstrument = #"pizzicato strings" 
in the middle of the music.  This generates a program change message in the
MIDI file that should change the voice used for the relevant MIDI channel.

There is a new feature 
<http://lilypond.org/doc/v2.14/Documentation/changes/index.html>
  \set Score.midiChannelMapping = #'voice 
that puts a different port assignment for each voice at the beginning of
each track in the MIDI file.

Many of us cannot use this feature, because hardware MIDI synthesizers
have only one, or maybe two, input ports.
