Unable to record from Groove Agent

I have the Cubase LE/AI version and upgraded with the elements 8 on a windows 7 PC. I cannot record tracks from the groove agent or the halion sonic SE. The instrument track recognizes the input and the meter responds as well and the track turns red when I hit the record. But nothing records. The recording track that begins when you start recording is grey and shows no instrument inputs, and then disappears when you stop the recording. I have used the Power Tools for Cubase and the steps outlined in the book give the same result. Is this a limitation of the program? If so, do I have to upgrade to Artist to be able to record from these?



Groove Agent and HALion Sonic SE are Instrument tracks. You will not record an Audio signal, but MIDI data. What MIDI Input do you use? What MIDI device do you use?
