HI, I have the Audya 5, used it many times on stage being a one man band and playing mostly country and rock and party, I also had the ketron SD1 plus and comparing the sounds correct me if I'm wrong here, but the SD1 I thought far out weighed the Audya 5's sound engine, overall though there is a lot more going for you I find when editing with Audya 5,but the one thing that upsets me when editing styles with the 5 is the arranger volume level sliders, wwhat should they be set at when editing to ensure great performance and control, I'm not cutting the Audya 5, I do think it's an excellent keyboard,
