RGB Matrix
I've got some generic led pars. I made a fixture for them. I can make scenes and chases with them. But, when I pull them into a matrix and try some of the presets in there, nothing happens. I've watched videos and scanned the docs. Are there any troubleshooting tips for this scenario?

1. check DMX monitor if the numbers there are as expected.
2. Is there some shutter/dimmer channel that needs to be set before you can see anything?
3. attach your files here
