Is Cakewalk Pro Audio compatible with Windows 10?
It's impossible to say if the software is compatible with Windows 10 or not, because there is no information about it. I've checked the official website and the only thing I could find is something related to updates and patches, but no mention of Windows 10.
If you have the software, download and apply those patches and then you can see if it works or not on Windows 10.
You should also check other products released by Cakewalk. They're optimized to support newer versions of Windows as well.
According to a friend, it will run on WIN10. He is the organist at the church.
