I have an old Roland xp-10 with a couple sounds that I'd like to record into LP9, but the sound is distorted. Never tried before. Is there an easy fix, or are these components incompatible now? Is there some driver that needs to be installed first? I'm not a tech pro, so I don't know the music tech language. I thought it would be a simple matter of connecting the xp-10 mono output to a 1/4" input on my Presonus Firestudio Project and recording to an audio track. I get sound, but it's distorted as if the signal is too strong. I tried adjusting levels, but no change.
