Digital Piano - Yamaha p255
Audio Interface - Roland quad-capture
I bought one 1/4 inch jack from a store near my house and connected my piano to the audio interface, and when I listened to that recording, there was a lot of noise, which I think came from the cable, as it was also when I did not play a note, and also, my equipment is certainly decent. I used it later with an electric guitar cable that I had which is also more expensive, and it was a little better but still, if I turned the input volume on the audio interface a little over the half, it would start making noise, and if I didn't, the recording would just be too quiet.
My question is, should I buy more expensive pl cables? Most expensive cables are designed by description to guitars, so I'm not sure if I would waste my money..
Would be glad for advices how to solve my problem.
PS. I know that it would be better to use 2 pl cables instead of one, but I'm not sure if that has to do with the noise problem.
