Now I've got it (at last, I hear you say) I need a RS232 to mini P/S plug 8 pin. This will connect to the 9 pin connector on the laptop and will have the midi in and out like the old cable. I didn't know that the USB port on the back of my 6000 was useless. (I do have a hdsx6) Many thanks for your time and effort. Now all I need to do is scource one of those cables.
