I recently installed Cubase 7 64 bit and then installed BFD2 drum instrument. I cannot get Cubase 7 to recognize this as a plugin. I had Cubase 5.5 running with BFD 1.5 and it worked fine
Have you made sure that you’ve got the latest updates for BFD2 as well as everything in the right places?
I found it easiest to set up the library locations - and everything else - from the standalone version first.
You should be on build 2.3.1 build 6, and you should also make very certain that Cubase is pointing to the 64-bit version - and only the 64-bit version.
Running fine here in Nuendo 6, 64-bit
