Hey guys, I have a bit of a problem. I tried to connect my Yamaha keyboard, which is only a cheap YPG-235, to my retina Macbook pro using the USB connection. Upon realizing that I needed the drivers before I could connect to Studio One or Logic. But when I went to Yamaha's website, I couldn't find any drivers for Mountain Lion, which is 10.8. If I can't get the drivers, it won't let me use it as a midi controller, so the questions are: -Is there a way to use the old drivers with my current OS? -If not, can a USB interface allow me to transmit midi data without the need of a driver?
