Multi transfer from Virus B to Virus C (solved)

    I own a Virus B, a virus Ti and recently bought the Virus C.
    I want to transfer the multi banks from the virus B to the virus C but it doesn't work...Tansfering the banks A and B is a piece of cake, just plugged the midi out from the virus B to the midi in of Virus C, then dump bankA and the sounds are dumped to the virus C. But this just don't work with the multi's...
    Any idea? Thanks
