I have a B4D that was given to me by a friend. So I have nothing but the unit itself. I have the B4II and I have the B4D connected to either my Yamaha MOXF8 or my M-Audio Keystation 61es. I am getting no response from the B4D. Do I need to connect it to the computer directly as well and if so, Where do I find that cable. My laptop doesn't have a 5-Pin MIDI connection. My MOXF8 has a built-in sound card so it acts as a sound card also.
