First please apologize if this as already been discussed, but I couldn’t find the answer. I am using Ardour 4.7.0 on Debian Sid, with Calf plugins from Debian repositories.
When using Calf equalizer 30 bands as an Ardour plugin, most of the controls are locked: I can “drag” them with the mouse, but they go back to default as soon as I release them. The only exceptions are the two “Gain scale” (and the generic “In level”, “Bypass” and “Out level”).
This problem does not appear with others Calf equalizers or if I use this plugin on the Calf host. This makes me think that Ardour has locked the settings, maybe to use it with some hardware equalizer (that I never had).
Would you have an idea about how to unlock it ? Do not hesitate if you want me to provide more information.
