Midi Problem With Bcd2000

I’ve just try mapping some of the sliders on my bcd2000 and it doesn’t seem to work .

When I open the midi map params and select something to be mapped Renoise doesn’t have any problem in detecting and assigning which nob i’m using on the bcd . But once assigned and i twist the nob nothing happens in renoise …

Edit : this only seems to happen when i use the bcd in asio mode
