The same reason arranger players buy EMC styleworks so that they can use styles from other manufactures, also Wersi instruments are Organ first and Arranger Keyboard second, (Which require different playing styles) it will allow arranger players (Or beginners) to transition easier while learning how to play the organ. (The styles on an organ are different to an arranger as arranger styles don’t work very well when playing an organ)
