By gad, Sir, I think you've cracked it! I can now program the inputs and use the "connection window" to mimic my MSR+ and switch the inputs around.
Tomorrow I'll connect it up to the rest of the system and see what happens, but it certainly looks exceedingly promising
And you're right about M-Config; it's almost worth getting a G61/68 just so I can play with the program
Many thanks for taking the time to explain it.
And I really should change my username
