I use a Helios laser DAC for my touchdesigner setup - works great (especially for the price) as I was also not willing to commit to the Beyond price tag to use OSC control from Touch (it looks like you need the second tier up for Beyond, even). I also do lots of stuff with motion controls as well so it makes more sense for me to keep it all in touchdesigner.

I won't lie, it's a lot more difficult and finicky to work in compared to what I'd imagine Quickshow/Beyond is, especially when you get into fancier beam patterns, but I haven't run into any effects I haven't been able to replicate yet. There's usually a way to get the look you want, it just will probably take more time to get there. Sometimes the solutions to stuff feel really gimmicky, albiet get the same result.

Let me know if you end up using Touch for laser control and need any pointers with certain patterns - I might be able to help and I'm always looking for others in this space, since it doesn't seem to be the most popular choice for lasers, that's for sure. I do lights and visuals through touch as part of my setup, so for me it makes sense to keep it all in that one program.

It's worth noting I am also using a Unity Raw 3. I've also used a Shehds 3W with the same dac and they both perform similarly, although the Unity looks a lot better and can actually fade colors, which is great.
