There seems to already be several issues with the SaberCore 3.0 where it will not turn on and the switch stays lit and the editor will not pick it up.
I too had to RMA my SC3 for the same reasons.
I believe it may be the external USB port that may be the issue.
Brax maybe you have heard something regarding this??
It is very disappointing to have to go without your addiction for too long...I’m getting withdrawals!! And it’s just not the same having to make saber noises myself! Not to mention no light effects
