I need help turning a stereo track into a mono track. I've tried splitting the stereo track and turing the left and right into mono tracks, and splitting the stereo track, deleting one of them and turning the other into a mono, but every time I try to put it into Blockland, it says, "Stereo sound detected in <name>.ogg file, removing datablock." And my add on is gone. Can anyone please tell me how to do it the right way? I think I'm doing it wrong. Also, if it matters, I'm a Mac user. And don't tell me I can't make music add ons on Macs because I've done it before the same way, it's just not working on this new Mac.
