I can see in the version comparison that Platinum is required to be able to create or edit your own themes. What is not clear is whether or not I can import custom themes created and shared by other users in Professional. I was going to just try it but don't want to risk breaking anything.

Edit, oops, I don't know with professinal.

Here are some themes, add one t your themes folder, see if it appears in preferences> themes

Thanks I was about to try it but I am afraid if I am actually able to load it and it doesn't work, I could end up with a blank GUI with no way to revert the change. I would rather someone confirm that it does or does not work.

The themes wn't affect the preference menu. Unless someone has created a theme with a black menu and text. Which I dn't think is possible

Ok then, I'll give it a shot. Thanks for the info.

AFAIK, the user created themes may be loaded into Professional. SONAR looks for user created themes in "Cakewalk Content\SONAR Themes." It will not break anything.
