Recently I have been using Touchdesigner with beyond 4 and 5. And it really couldn't be easier. It works correctly and in real tempo. In my case I only use Beyond as a bridge, I do everything from TD. To put a downside, it communicates directly with the laser, I understand, and the FX parameters, etc master doesn't work.
On the other hand, it is also possible to communicate through Ilda, of course, I have tried it and it works, fbut for my laser/mapping work to be able to do everything directly without going through ILDA is a blessing. I can do both laser and video mapping from the same TD, that's what gives me the power .
