Ok - I tried Yabridge once with Ardour, but had a difficult time getting anything to work. I think it is because I used a Flatpak-build of Ardour. I think I'll fork over the cash to get the pre-built binary (with upgrades) at some point soon to support their development, even though I could use the practice in building from source myself.

Good to know that it is not as hairy as I had the impression of.
