Please help. I have a KN 7000. As you know it has a panel memory : one through eight where you can store eight favourite instruments in Part A and eight more instruments in Part B. Just above the black and white keys there are pictures of Percussion instruments eg. snare drum and cowbells. Recently I noted that when I play any instrument in Part B of the panel memory, I hear the programmed instrument as well as a percussion instrument concurrently.For example I will hear a piano as well as a cow bell ! I did try factory reset but that did not help. Is this a malfunction of the main Panel memory switch? If so I am unable to find a Tecnnics repair centre in British Coumbia, Canada. Any help and advice will be greatly appreciated. Thank you, Naz nazmerali@shaw.ca
