Any RealTracks can be made as a "Bluesy" RealTracks by selecting the checkbox. "Bluesy" RealTracks will use more blues scales (e.g. Bb note on a C chord). This only works for Soloist or Background RealTracks, not for chording ones.

RealTracks soloist will play in a bluesy style, where major triads are treated like 7th chords.
