Hello! i have a digital piano connected to a computer via a roland UM-ONE midi cable. I play in the Kontakt Player program and I have the following problem. I am loading a church organ that has 5 registers. I want each register to turn on separately by pressing a button on my piano (not a key of a certain note but a button above them). In the program, I right-click on each register separately and click learn midi and set them to different buttons. But whatever button I press is always one and the same register, it doesn't change. As if all the buttons on the piano have the same address. Does anyone know what the problem is?
