What I would like to do, is transmit from via widi from the accordion to the Ketron arranger for playing, and transmit from the I pad to the arranger for all the program change messages. I think Stage Traxx is the best thing since sliced bread …. My problem is, I can hook up stage Traxx to the arranger with widi….or I can hook up the keyboard to the arranger with widi…..but not both at the same time….. I’m sure I must be missing some little thing, but don’t know what….
