Thanks EWB

I read a lot of threads on the fractal forum before asking here (includng this one).

Ironically, just after posting I swith off/on my Axe and it works now... I'm pretty 100% sure that the problem comes from the Axe MFC output. It seems to be broken because it doesn't "click" when I plug the MFC cable in it. The connection is not working properly. The only solution is NOT to move the Axe now. I didn't know how this works before buying the Axe and it's sad that the previous owner didn't told me that...

I also hope that this problem didn't broke anything else in the system!!

The question now is : is it possible to control the MFC 101 (to change scenes) with a midi cable and an external power supply?
This would resolve my problem since the midi connection works good on my Axe and the MFC

Thanks !
