I’m very new to recording. I have a Privia PX-760 and I’m trying to record myself singing AND playing piano. I just bought a Focusrite interface but realized too late that I don’t have the right cord to connect my piano to it. I have a USB-B to USB-A. Obviously this won’t connect to a Focusrite. Can someone please help me understand what I need to do? I really don’t want to buy a whole new piano.
