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?
