I did my RGB programming in xlights last year then imported into LOR and ran my show from LOR. I do not remember having to tell xlights to "stop" at 510 (for example) and restart at 513 and I do not see a way to do this in the models' channel setups. I do think I setup my universes as 510 each, so that might be the trick. Anyone who is more adept/practiced at this; I would appreciate your input here!!!
