sometimes i get error messages like this [ERROR]: control protocol XML node has no name property. Ignored.
[INFO]: Loading session /media/data/data/Productions/Lennons/Unplugged/Abschied/Abschied using snapshot Abschied (1)
Loading history from ‘/media/data/data/Productions/Lennons/Unplugged/Abschied/Abschied/Abschied.history’.
when I open a session. What is the meaning of this? And what can i do against it?
You would know if you were. You would be using something else to control Ardour other than your keyboard/mouse and its GUI. ie. A MIDI Control Surface.
