In LilyPond terminology, the limitation is that you cannot have more 
than 16 Staff contexts.
In the MIDI version of your score, you can try to include several voices 
in the same Staff, for example all violin parts in a single Staff, all 
flute parts in a single Staff and so on. Obviously there's still a 
limitation since all the voices you put in the same Staff will share the 
same MIDI instrument, i.e. they will sound the same.
