I have a Yamaha PSR-79, and I correctly connected the MIDI cable to my Audiobox USB interface, but when I tried to configure an external device in Studio One, it kept saying that there was no MIDI keyboard connected and only gave me the option to 'Receive From' Audiobox USB and did not recognize anything else. I added and named the device, turned all of the channels on, turned the keyboard on before trying to add it, but it's still not being recognized. I'm not sure exactly what to do here so if anyone can help it would be greatly appreciated.
