I have a yamaha YPR-50 keyboard and a MacBook Pro laptop. I first got MIDISPORT Uno MIDI/USB cables now I purchased a EMU MIDI/USB cable. I downloaded the driver software off the yamaha website and installed it. But I am not sure I got the right one. I think I did. I am far from a computer expert. I just want my keyboard to work on my Mac. Help Me
