Hi Henrik,
after some quick tests, I can deal with our two options (changing
feature_mapping signature or not, and so calling feature_mapping
before or after input_mapping).
So, my questions are:
- do we really need to change feature_mapping signature?
- is feature_mapping tied to an input or to a device?
Cheers,
Benjamin
