I have tried connecting my digital piano to my audio interface using a 1/4inch cable but the sound quality is very poor. The yamaha ydp 143 has 2 phone inputs which are used for adding headphone jacks mainly and nothing else(besides usb connection of course). It doesn't have a label for left and right like some pianos do. I need to know how I can use that interface with the Scarlett solo that I have to record good quality.
I read that digital pianos are stereophonic instruments and it seems like my only option is a mkno connection which is giving me this poor quality audio, so how can I pull this off with the hardware that I have?
