There is no correlation between your audio interface and Studio One in terms of upgrading and / or licensing.
You can use what interface you want and upgrade your Studio One 3 to 4 without any trouble.
Why do you want a different interface if I may ask?
Presonus has the best "value-for-money" interfaces you can get your hands on, and if you're going to use Studio One, there is even bigger reasons to stick to a Presonus interface. They come in all shapes, sizes and prices, but they have one thing in common:
They are all great sounding, good quality interfaces, and work seamlessly with Studio One.
