Should i downgrade to 32-bit windows 7?

Now, from researching, i know im not the first person to ask this question. But i can't find any answers relating to my specific case. I have 64-bit windows, and really theres only one big issue. My casio wk-110 midi workstation doesnt work with my computer because there's no 64-bit driver. I've tried everything from calling casio asking why they wont make a 64 bit driver to attempting to use drivers meant for other midi keyboards. The only thing i want to use my computer for is games (mostly gameboy and n64 emulators) and writing music (which i use reason 4 for.) But i cantt write music iff i cant use my keyboard. I just want to know if downgrading to 32-bit (i am aware i'll lose all of my personal settings and files) would affect my computer's performance in a way where it wouldnt be worth it. Thanks.
