I have used various chord combinations of Realtracks to produce the melody in many of my songs arrangements.
Here is one songs on my site. The song is in PD but the arrangement is my production.

The Melody is embedded in the chord and realtrack instrument selection.

Other songs on my website have also arranged using this concept. Some better than others.

Nice arrangement. The melody isn't really popping out for me, though.
