With the titles I could have given an exact description but from the sound of it so far:
Bank A are normal auto play variations.
Bank B are soloist chord progressions programmed into the composer, thus you do not have to change chords during these "break" variations but can improvise right hand in a similar way to 12 bar blues. They will cycle a chord progression around whatever starting chord you trigger and end at the same chord or suitable dominant lead back etc. Naturally you improvise mainly around the played starting chord of the auto progression. There is no display because auto chord is not operating, it is playing the constant starting chord, the composer pattern has the chord progression programmed internally.
Bank C are variations for the KN3000 composer chord map function. This is now redundant, replaced by the chord modify change introduced on the Kn6000, and triggered a different variation depending on the minor, seventh, diminished chord being played. You can still use the major pattern normally.
If they are still Kn3000 format they could do with some tweaking to sound excellent on the 6/7k.
