Hey bitflipper they actually do not share the same vst inventory. I already took care of that. That's why there is a full VST scan when you install CbB.
SONAR's inventory is here HKEY_CURRENT_USER\Software\Cakewalk Music Software\
SONAR\Cakewalk VST X64
CbB's inventory is here HKEY_CURRENT_USER\Software\Cakewalk Music Software\
Cakewalk\Cakewalk VST X64
So they are already completely independent.
PS: I just added migration from a prior VST Platinum/Artist,/Studio etc inventory to the new CbB inventory. This should
greatly improve the first run experience if users choose to migrate settings since it will no longer need to rescan the entire set of VST's but use the results of prior scans. This is the most troublesome area when we do new products so I think it will improve things a lot.
It will be there in the next update of CbB.
