Michel, I don't want to have to bring a computer to every event. Now that I think about it, pt-itrust is not exactly safe because you can't control zones or where the lasers hit. Although, I know there is a way to achieve putting pre-made shows onto the memory card I have on my FB3 interface and this way it is not only safer because I can make them not full scale, but I still don't have to have the computer. I'm probably going to just have to find someone to send me a pre-made shows on a memory card as I've read in the forums it's no longer achievable with the latest software and firmware and they are no longer supporting it.
