I am having a problem with the Demo sound not working when playing the Demo.
It only works once in a while. Have initialized a couple of times but to no avail.
Has anyone had this problem and can anyone give me a clue as to what might cause this problem aside from a malfunction needing a repair? Thanks in advance for advice. Lloyd

If you have expression pedal it must be other position than minimum when you press demo button. There is a bug that it doesn't read expression pedal position anymore if it was minimum when you start demo.

Dear Jarmo:
Thank you so much for the input. That is what was wrong. When I would go to play the demo I would let up on the expression pedal and try to control the volume with the slider.
I even went to my dealer and he was going to make a service call appointment.
Thank goodness for this forum and people like you who answer these perplexing problems. Do you think this "bug: will be corrected by Technics. Thanks again for your help and a solve to my problem.
Sincerely, Lloyd
