 The instrument project nearly stalled after a breakdown in negotiations between Japanese and United States staff, the latter of whom insisted on manufacturing the case in the United States and designing the organ to identical specifications to the original.The company has since released the XK-3, a single-manual organ using the same digital tonewheel technology as the New B-3.The XK-3 is part of a modular system that allows an integrated lower manual and pedals to be added.
