If the Demo only allows you to output 16 channels, it should have no time limit at all. The program has gotten too big and too complicated to really learn any of it's real capabilities in 30 days, especially if you have a life and responsibilities. If the price was more DIY then it really wouldn't matter as many would just but it and see what it can do but at its current price, I simply can't see doing that, at least not yet. If Vixen can do half of what it claims to be able to do by the middle of the year then that's what I will use. If not then I will look as LSP again but I have a hard time spending that kind of money for software to light up Christmas lights.
