I know this is an old thread but I didn't want to create a new one.
I am working on a setup that uses 4 Gobo lights with a DMX 512 controller. They have been using one light on address 1, which sometimes serves as a spotlight, while the other 3 are on the same address 17. They use scanner 1 when they want the spot, and scanners 1 and 2 together to control all 4 in conjunction. The owner would like to mimic this configuration in MyDMX3. I have set it up to respond properly to the sliders, but the software GUI only shows a single Gobo for that address. Is there a way to do this?
