When you select the rehamornist for the entire song (Window - Auto-Generate Chord Raharmonization)there are two options that I can't find any explanation for in the manual. They are:

Mix Chords from Major and Minor Keys (%) and
Number of variations (range 1 to 100)

Does anyone know what they are intended for? I've tried various values but I can't see any noticeable difference.

Thank you!
