Question

I can upgrade free to 12 months of Sphere. Will I still be able to upgrade to Studio One 5 at a later date if I decide I dont want Sphere. Yes I know I will have to pay the upgrade fee.

Answer 1

Yes. Your current perpetual licenses are separate from the Sphere activated versions that you may install. Should you end your subscription you'll still have Studio One 4.5 in your account and you'll still be able to update to a full perpetual license of 5 if you choose.

Answer 2

Licenses paid for are always separate.  Sphere gives you access to version 5
