Signed up in January, just now jumping into ACL to learn more about pixel displays. For the last 3 years I have been heavy into LOR with 192 channels. I tried a little bit of DMX in 2012 with some simple 3 channel controlers from HolidayCoro.com, another great learing site. I have already been looking into the forums on LSP. Since my investment in LOR and leds is extensive. I will attempt to work both LOR and DMX as I expand my display this year and into the future. So many cool things can be done with pixels I can't decide where to settle in...think it will be a matrix mega tree. Ready to explore and learn.
