That was back in the dark days before Tony and I were mates

Yes, a factory restore would have done the trick, but to be fair this was very early on in the life of the Audya (Tony was one of the first people in the UK to own one) and the UK distributor had literally only just taken on Ketron so must take some of the blame as no restore disks were available for a few months and either the engineer had to go out to the customer (which he did on more than one occasion) or the Audya had to be collected by the distributor (they paid freight even in the case of user error). Things are a lot smoother now thankfully!

By the way, Tyros 3 was more expensive than the Audya at the time (by about £250).
