Stephen, I'm pretty sure what you should be recording is what Roland refers to as the "NTA" (Note To Arranger.) These are the notes played in the chord recognition area of the keyboard which are interpreted as input by the logic engine.

For example, a I vi ii V7 progression, two bars in 4/4 time might be: C2-E2-G2 (for two beats), C2-E2-A2 (for two beats), C2-D2-F2-A2 (for two beats), and (D2-F2-G2-B2) for two beats. Presumably the arranger would interpret this as C major, A minor, D minor 7th, and G7.

What exactly comes out of the style tracks depends on the style and what was initially recorded. Hope this helps. -Ted
