FA 06 with Ableton 11 & big sur

[NOli]

Hello,

Is anyone here use Roland fa 06 with Ableton 11 on Mac OS Big Sur ??

My problem is that my computer doesn't recognize my keys. In preferences of Ableton, there's nothing.. I can't control anything in MIDI.

Maybe, it comes from my multi usb that I connect to transform usb a into usb c ?

For now, I'm using and interface beringher and an old midi cable but that's pity I can't use the usb way...

Thx a lot for your answers !
