Sure. Here are the first four measures of a song I'm trying to tab. Notice 
that the first 2 measures use a single note (a) as the chord. The midi file 
plays it as violin.

In the 3rd and 4th measure, I'm using chords a and e and the midi file plays 
these with the piano instrument instead of the violin.
