Shoot, so my fix only works for some version of Ardour and not others? That’s frustrating, I thought it was resolved. It’s working for me on two different Linux machines, both running Ubuntu distros and a version of Ardour I downloaded directly from their own servers.
I’m glad that you got it working, but I would rather it works Ok with all versions of Ardour. Did you try it with Reaper or Bitwig? The problem appeared there too, before I fixed the plugin ID issue. Maybe you can try them it if you get a moment. If not don’t worry about it. I don’t blame you if you prefer to have some fun with ToneZ instead
