Thanks very much Mike. They say you learn something new every day, but it beats me why IT people feel the need to obscure clarity by creating their own private dictionary!
Incidentally, it has just dawned on me that the usb/midi cable you mentioned is probably used in reverse, in that the usb end goes into the computer and the midi plugs into the keyboard. So perhaps I can buy a cable and do as you suggest after all.
Very many thanks for all your help. It,s much appreciated.

Regards,

David
