Man this is so intimidating, where do I begin. How are there not any fundamental instructions on how to hook this puppy up, as in, which cables go where? I have a Roland TD 17KVX with USB cable running straight into my MacBook Pro. I have the Roland TD 17 selected and everything, the 17 is selected as the midi device, the output device I have set as The TD-17, I am just not getting any sounds I cannot hear anything from superior drummer three. Help?
