This is my first post so I just want to salute all of you guys responsible for giving us this great great great DAW!
Anyways, I’ve got this problem with samplv1 - lv2 plugin (also padthv1 and synthv1). Basically regular gui does not work - there’s only big blank gray empty window with: pinout (none) add save delete etc at the top of it. Generic Ardour’s gui works just fine but still.
I’m using Ardour 5.12-7 and Samplv1 0.9.3-1 both from community archlinux repos.
