I don't know if others are seeing this, but when I first installed CbB, 4 of the bundled plug-ins were missing from the list of available plug-ins for use by Cakewalk.
These are the Boost 11 limiter, the Percussion Strip, the Tube Leveler, and the Vocal Strip.
If your clean install or upgrade of Cakewalk is missing them, to (re)enable them, go to the Utilities menu, then select Cakewalk Plug-In Manager.
When Plug-In Manager comes up, click on VST Audio Effects, and down below, select Show Excluded. In the middle column, you should see a list of 4 plug-ins, Boost11, Percussion Strip, Tube Leveler, and Vocal Strip.
You may enable these plug-ins by clicking on their names and then clicking on the button Enable Plug-In, which is down below the left-hand column.
I don't know why they keep getting excluded; they work just fine once I enable them.
