Ted: I found a problem with the Expression Pedal connected to the KN7000.
If you do not have the pedal depressed (Volume at a level higher than off)and try to play the demo., it will not sound. The screen shows that the demo is being played (picture and printed matter show on screen).
I posted this on Synthzone and thank goodness I got a answer to this problem from a owner.
Was ready to call a serviceman.
The master volume will have no effect if the expression pedal is not pushed part way down.
Hope this is solved by Technics with a patch.
Hope all KN7000 owners will see this so they will not suspect that the demo has failed completely.
The answer to my problem came from Synthzone and this is why it is so important a site.
