Can anyone help me out? I just got Reason 4 and a Yamaha mm6 and i want to use them together but the Yamaha wont show up but that another question for later. Im using this other beginner casio n it shows up fine in reasons and everything was working until i create my 6th or 7th track and i cant get an sound from the created track but when i click on the previous track that was working it still does. What wrong?
