I have a DMX Operator Pro on order but have downloaded the user manual and began reading up on it. I am confused about some terminology. It refers to scenes, pages, and chases. There are 6 scene buttons and 6 chase buttons. However 16 pages can be programmed. Do I understand correctly that there can be 16 pages within a scene? If so, where do chases come in? Can someone explain the heiarchy and how they all relate?
