Listening on the headphone of the piano what is played on the piano and the PC
I would like to listen to what is played on a pc and my piano at the same time over the headphones. For example, I would like to listen to the instructions by a software music teacher (such as yousician) and what I play. How can I connect my PC (where I run the software teacher), my piano and my headphone? what hardware and software I need and how to connect them?
