I am aware I could probably get those windows plugins working again with a bit of wine + yabridge fiddling but want to take this opportunity to move towards more linux native plugins/synths.
ok that wasn't so bad, there's an issue here with yabridge:

I downloaded the fixed version and ran yabridgectl sync and it was all ok. YMMV
$ wine --version
wine-10.0 (Ubuntu 10.0~repack-11)
