Hello everyone, this is my first post, please bear that in mind. Just received my ketron sd2 with the usb uno midi cables. In realband I created a new midi track..added some notes in Notation assigned the track to usb uno midi interface channel 4 patch 41 violin. I made sure midi device output showed the usb uno and put it on top of the list...played the song and heard output sound BUT not from the ketron....also ketron was not blinking...to make sure I unplugged the usb device and still heard sound. Since I heard sound it can't be my audio driver...so, what can it be....can anyone help me please? Thanks so much for your time.
