Greetings. I am trying to use my Casio CTK-750 keyboard as a midi controller with MM 2013 Premium/Windows 8. I have connected via a digiflex USB/midi cable and selected USB Midi as my Input device in settings. I downloaded ASIO4ALL v2 and selected that in the ASIO driver box. I I can't get any input from the keyboard. I would be very grateful for any suggestions. Many thanks - Jon.
