I don't know what I'm missing but I have tried so many ways to save the system settings and I can't figure it out. Right now I have redo the settings every time I turn it on, and what's even worse is that the PX5s shuts itself off between sets so I have to do it every set. I can't imagine that any company manufacturing professional keyboards would be stupid enough to have left something like this out, so if anyone out there knows how to save the system settings please let me know.
