Hi Nobby: Sorry if I didn't make myself clear, but I did'nt want to actually delete the 'registration bank file' from USER memory, I just wanted to be able to remove the contents 'already loaded' into Registration Memory (1-8) or at least shut off the Registration Memory button (1-8) feature altogether. Anyways, thanks for your excellent instructions on 'how to' delete Registratiion Banks from USER memory.
