Hi everyone, since yesterday the synth is not recognized by my computer anymore when I connect it via USB. I have tried with several cables, and with different ports on the computer, but the Super 6 still doesn’t show up on my computer (a MacBook Air with Catalina). Until yesterday it was working fine, and I haven’t made any changes whatsoever in my setup, so I can’t figure out what the problem is. Do you have any idea on how to fix this ? ---

Isn’t there a power-on button combination you have to press in order to get it to show up first? Wonder if that’s been reset at some point. ---

Not that I’m aware of. Until now it was working without any manipulation. It’s pretty confusing. I tried to plug it to an other computer but it still didn’t work, and the usb port of the synth doesn’t seem to have any damage 😕
