Thanks for the reply.
The problem is it is NOT shown in the Project window. See my frame capture. After "Clock", there is nothing more. The Surround tab should be there.
Wanted to try Cakewalk and downloaded and activated On 15/10/24. I wanted to mix in Surround. However the Preferences window panel does not show Ssurround as shown in the reference manual. What went wrong?
Thank you.
