Hi, I recently bought a Yamaha NP-31 and I want to connect it to my computer so i can record music. I have a midi interface USB cable and I use Cubase 5 for the software part. My computer recognize when i plug in the cable, but when i'm in Cubase I can't get any audio from the keyboard. I have looked at different tutorials on how to hook up a Midi device to Cubase but I no sound is being picked up. Cubase recognize that I have connected a Midi in and out. I wonder if there is a driver or something that could solve the problem. And also Cubase does not include the Yamaha NP-31 in the list of different Midi devices, so i have to define a new.
