Hey Paul,
thanks for your fast answer.
I am not sure what you are trying to tell me :)
You don't seem to believe it is a good idea in general.
Well, some of our competitors do exactly this behaviour.
I think it is good to have a solution like this since many of our users
are not quite fimiliar with any technical stuff, they just want to play
music. That's why automatic selection is a good idea from my point.
I also have a fireface 400 here :) This is one good example where channel detection
is always successful. I believe the overall problem is wrong firmware.
regards
Matthias
