One thing is that free CbB "support and development is discontinued", a totally different thing is the fact that it will be on purpose stopped working. Why do this ?? Just eliminate the activation and leave CbB working at user's risk !
I'm using Cakewalk @home since it was just "Cakewalk" ~20 years ago, then Sonar Producer & Platinum (free and purchased updates) with a lot of plugins added. Not for professional use.
I was going to purchase the new Sonar Premium, to get more features and contribute to its development, I'm happy to,
but I stopped because I don't like pay-per-use software and free/purchased versions will no longer work.
Hope to have misunderstood something.
EDIT 14/08/2025:
there's a Sonar free tier available with less features than the paid version (IMHO that's fine), from my test completely compatible with CbB. During installation it asks to import CbB settings to (suggested).
Both free/paid versions have a new graphical interface (1 fixed theme) not particularly pleasant to see because it's flat, dark and more confusing. But it was my understanding that is because it was rewritten to allow big screen and GPU acceleration.
So probably there will be some improvement in the near future.
