I do not know if ProteusVX is supported anymore, nor do I know if it works these days.
The EMU site indicates it as 'End of service life', and it is no longer downloadable from their site.
For EZ Drummer, the support page on their site indicates it is unsupported with BitBridge, and that you must use the 64-bit version. Is it possible that you have a 32-bit version installed? If so, it sounds like it will NOT work in a 64-bit Sonar using BitBridge.
EZ Keys has a current version of 1.12 - I do not know if it is 32 or 64 bit.
EVM Bassline is a 32-bit plugin. I do not know if it works well with BitBridge in 64-bit Sonar.
The TX16Wx has a 64-bit version, so it likely will work OK.
So, try using the 32-bit plugins in a 32-bit Sonar install and see if those work OK. They may or may not work in 64-bit.
