i have purchased LSP pro buggy is one way to describe it, tried importing vixen sequences not one would work. Posted msg on LSP forum for help never got a response. need a highend processor and lots of memory (it seems to me) to get anywhere. I had to wait a couple of minutes for the system to plot everything when adding channels or events. I was thrilled at first when I bought but have gone back to vixen because its the only thing that works for me consistently
