I've created a 16 bar minor blues with the first 4 chords being: Am7 E/G# Gsus F#m7b5. After the first chorus is played consistent with the chords as written, these 4 bars are played by BIAB as Am Dm Am Am for the remaining choruses. Why the change, and how do I preclude it? I have Natural Arrangement turned off. I want to continue with the chromatic movement in the first 4 chords during the remainder of the choruses. Any help/advice would be much appreciated. Randall
