Adding my request to PLEASE improve and optimize S1 CPU for multithreading. For those of us that like to use plugins like Acustica, this is a must. I have to confirm with the above comment regarding people leaving S1 for Reaper, all because the CPU optimization is significantly better. Two instances of a plugin that takes 9% in Reaper shouldn't take 48% in S1. That is ridiculous! Get with it dev team!
