Well, I have the money to update pro tools but do I also have the money to buy upgrades like battery 4 and lots of other stuff? I mean this is how they make their money. Compatibility. And (my opinion) this is also how they make people like me feel scammed, at least a little. You spend a lot of money and suddenly it doesn‘t work anymore because of „compatibility issues“ even if it easily could.
I will update once again now and then never anymore. It’s not like much better music than nowdays has been made with much „cheaper“ equipment 50 years ago
