Hi Mark. Thanks. I did change the Touch Sensitivity in case it was that and then put it back.
When you talk about the Main Volume, you mean the normal Slider switch I presume. I saw on this Forum something about dust sometimes getting into the Sequencer Volume Slider, and fiddled with that a bit, but to no avail. I might try the Main Slider too.

I've just noticed that the casing at one end of the keyboard is damaged. My husband propped it up on the floor on its end and I noticed that top & bottom were pulling away from each other!

The reason he took it off the stand & propped it up was - wait for it !

- I've JUST GOT HOLD OF A KN7000 !!!!!!!!!


But I fully intend to try and get my beloved kn6500 sorted, still !
