Hi,
I found this thread and have the issue. I have an old model privia px110 with no digital display. It does have midi in/out ports. I have a USB midi interface adapter. I cannot connect to logic pro or any DAW on my PC. At least not now. I did once briefly, so I know it's possible. But since unplugging I have never again had success. Is there a function or something that needs for it to work or should it automatically switch to midi?
