I haven't looked at the details of the MIDI format for 
several years but from a quick look at the descriptions
at www.wotsit.org, it seems that you can only have 16
different channels in a MIDI file and each channel
corresponds to one instrument (and one Lilypond Staff
context). At the moment you have 18 different instruments.
It might help to reduce the number of staves for the 
MIDI output to use only one for each kind of instrument
and let each part correspond to a separate voice.
This means you probably need a separate \score{} block
for the MIDI output.
