I have a YDP-131 (Yamaha Digital Piano) and I bought a Midi to USB cable on Amazon to connect it to my laptop. Cubase (Artist 7) has installed correctly (sometimes it say 'Cubase has stopped working' but I can still open the program. My laptop recognises the cable, however, Cubase does not recognise the cable (something is not registering) and I cannot play anything through my piano onto Cubase. The wire has a power light which turns on so I know that their is some sort of function, but I do not know how to fix this...What do I do?
