Some more information:
everytime I press the switch I see the busy-led light once, and when I release the switch again the busy-led lights once again, so that's normal I suppose. When I try it on my Voodu Valve the full range is recognised, from 0 – 127 ( 0=off, 127 = on ) so that's normal too.
I hope you can help me out, for me midi-switching is essential
