Hi everyone I'm new here.. I need some advice please ..I have a DGX-660 hooked up via usb to a laptop. I have Propellerhead Reason 11 installed. When I hit a note on a keyboard it seems to register in the software. On playback I hear nothing. In preferences /audio/audio card driver I have tried them all with no luck? Can I switch off the piano sound as I play? Thanks...
