Hi Andrew

"I am not sure if the VST is actually functioning, is there any easy way to tell?"

All I can say say is it works fine in 2019 32 bit and has been my default synth for the last 2 years at least.
As far as 2021 goes,
The only extra thing I saw was a yellow pop up saying Yamaha .... could not be loaded for an unknow reason, when I first searched (scanned) specific folder.
and yes it is strange that it does not show it's name just vst:
maybe the new version of BIAB requires some sort of gui as it allows multiple gui to be open.
Thank you for your time.
Mike
