I am new to playing the keyboard. Someone gave me a MOX8 and I have been trying to get it to play through my Asus pc with Windows 10 which I have finally managed to do. I do not have an amp yet so I have been using headphones. The PC is connected to a surround sound system. While connected to the pc, the sound out of the PC through the surround sound system from the MOX8 is just plain piano. Even though the "Voice" that is showing on the display is "MO Xpressive" and through the headphones I hear a drum beat and the keys sound similar to an organ. Can anyone help me with this so I can hear on my PC what I hear from the headphones instead of just a plain piano voice. Hopefully, this makes sense to someone.
