For liturgical music, a "sync stop," or a way to silence the style when the keys are released in the chord recognition area is a must-have. All of the mid-range keyboards from other brands have this feature. You might be able to stop or fade out the style by using a foot pedal, but it would be very awkward. Would it kill Casio to add a button for this, or a menu parameter?

Full-size midi controllers and drawbar organ modules are available as add-ons. IMO styles, style flexibility and control are what define an arranger, and these boards don't measure up to other MOTL offerings in this area. My $02, anyhow.
