Hi John,
Great response and a pretty good guess considering Walt's request. In this case, Walt has a "special" projector that requires LivePRO (and for that matter, all LD programs) to output a value to a DMX channel as long as scrolling text (or for that matter, any content) is being output. This can be done in version 3.40 or later, since we now offer a "DMX Shutter signal" to be output on each zone. It's like getting an extra 20 DMX shutter signals. Each zone may have a different DMX "shutter", or the same DMX shutter.
We will be releasing version 3.50 soon which will surely have this feature as well. In the mean time, if anyone else needs this feature, just write me a private email and I will send it to you.
Bill
