Cubase LE 8 AI with 2 FP10s

Hello, so my issue is when I go to assign my vst inputs Cubase will only allow me 8 inputs. I have 2 fp10s with a total of 16 inputs. I can assign all 16 inputs, but Cubase will only allow me to add 8. Is it the version of Cubase I’m using? I can upgrade to Cubase 9 for $50 but I don’t want to if I’m going to have the same issues

Yes

Since “Cubase 9” does not give a real hint about which actual version this really is, you should check the specs for the version, you intend to buy.
