Hey welcome to the forum!
Triggers will probably be fine since in theory Hypno should clamp them, CVs will definitely need to be attenuated 1/2 to scale into the standard eurorack -5-5v range. Hopefully someone around here has a pulsar to speak to the most effective way to do this.
I can’t speak to Maths because I have never had one. For function generation my personal favorite is Stages, I have seen @Winston use Zadar with good effect also. May want to check out this thread: Our Favorite Eurorack modulators for Hypno
Please make sure to check out docs.sleepycircuits.com and the videos linked there from our youtube there are a number of videos on how to implement hypno in setups with a few other pieces of gear so maybe that will get the wheels turning for ya. This is a great vid to start with to get some concepts down: How to Create Audiovisuals with Moog Mother-32 and Hypno - YouTube
