I have a PX-850. During covid I am taking piano lessons over Facetime. The sound quality isn't great. What I'd like to do is connect my px-850 to my MacOS laptop (via USB?) and be able to pipe both the keyboard and my own voice to Facetime so he can get the best possible sound quality. Is this possible? Will I need to purchase a USB-A to USB-B cable to connect the Privia to my laptop? And if I do this, will I, and my teacher, be able to hear both my own voice (via my laptop's built-in mic) and the keyboard?
