Hy, I am a new Ketron user and I've some problems with my XD3 due to the power suply. Now thanx to Mauritzio from Ketron Service, I can use my module but still I have some problems. I use one 88 hamer action piano keys as the master keyboard, and another keyboard - Roland Ax9 as a GM controler, that is plugged in Midi 1. When I play with styles, I can use the controller, but when I play Midifiles the sounds are garbled and I play drums soundr, mixed with pianos and other instruments. Thank you very much. I also have some other problems waiting to be solved.
