Just got the MK3 keyboard Friday Dec 12 ..with not being able to get the Mk3 to be recognized on my Music Production Wins 10 Pc threw supplied USB-C Cable . Keyboard would power up but the firmware updater could not see it and the Keyboard MK3 was not listed in Printer & Devices or Device Manager .. Nothing wrong with USB-C plug on the Wins 10 pc ...Any else I plugged into it did and does work as it should ... spent most of my Saturday and into Sunday Morning with trying anything and everything with no prevail ... Sucks !!! .. I have a new Wins 11 Pc that I am building for Music Production ... I tried the MK3 Keyboard on it ... had no problems .. Firmware updater and the Wins 11 pc recognized it right away all is good there !! The problem is why is the MK3 not work with the Wins 10 pc ...I'm not ready to switch to the new Wins 11 pc. I have the MK2 Keyboard and it works great on the Wins 10 pc ...I'm thinking ...I'm taking the MK3 back but not sure yet
