Sorry Nigel, I hadn't seen your question
Our sick KN 7000 is well documented under Naughty KN7000
----- Page 3 ---- of Technics forum
Interesting as it seems like a record as to how many viewers that topic has had. [over 7000 viewers ]
The problem is still the same so the k7 is being used as a straight piano in the meantime .
Only suggested clue is a possible faulty " Flash memory "
I have not been able to have anyone that has experienced that problem -- so still waiting.
