Hi, Have tried to make my connected external keyboard work in Cubase 5 but somehow it wont connect in Cubase, I don't know what's wrong really. I connect the cable from the Midi In/Out-ports on the keyboard and it goes to the USB-port on the computer. I also tested the connection with Midiox and there is nothing wrong with either the cable or the keyboard. It plays sound through the computer MIDI-card, no problem. Then I try the same in Cubase using the Tutorial no. 5, no sound. I try to connect it to a VST instrument etc, no sound, but the virtual keyboard works. I really have no clue what is wrong here. I took a look in the "VST Connection" and the tab "External instruments" and found that under "Device Port" it says "Not connected". I cannot switch to anything in that either so could it have went wrong somewhere? I could "open" ports from the keyboard in Midiox making it work but can I do the same in Cubase somehow, or is there any other workaround? Keyboard using is a Casio CTK-451. I provide you a screenshot of the VST Connection window if that helps. Appreciate any help.
