Hi. First of all i'm going to say "i'm sorry for my english". Hope you will understand what i write I would like to use The Casio PX-5s as Master Keyboard,using as Software "Cantabile Performer". Though i'm able to send midi signals to the program using the SLIDERS, i can't say the KNOBS are working as well. It seems knobs don't send any midi signals to the program. Somewhere else, on the forum, i read a "question-answer thing" ----> "Do Knobs send midi via usb?" "Yes!". Well, i can't figure it out. How to do that?
