I have my computer volume and studio one volume all the way up to max yet no sound is coming out when i try to play back what I've recorded. It's receiving the MIDI inputs, I can see them in the editor, but no sound comes out when i try to play it back. However, I have a microphone that I've connected to my computer and it records and plays back on studio one with no problem. My keyboard model is DGX-230 and I've connected it via usb, and I have the latest version of windows 10 installed on my computer, if that helps
