Miden and James,can you also test this. if you use headphones, press phones key and then set main mixer slider up or down, you get modulation effect on specially layer 4 sound, and for get off the modulation effect you have to press reset key!!!!!!!!!!!!!!!

I get this problem a long time, after my MS is repaired.
