main Cardinal is faulty in Ardour Plugin Manager

[magnetophon]

It's only the main version, both the synth and the FX version work just fine. All three versions work in jalv.gtk, so this could also be an Ardour bug. How do I find out?

The error is:

Known Ardour bug, it does not support CV ports even if those are marked optional.
