Hi,

I have somewhat similar problem. Below certain and not always the same key my Matrix 1000 generates tones of significantly lower volume. Could be they are also different sounding, but it's hard to tell.
Did you have success with battery test

It also happens in edited patches - above the 'split' seems to be the one that corresponds most to what I set in the editor. All voices sound the same above and below the 'split'.
