I wonder if any of you can shed some light on this problem.

For some reason the B3 Over voice will come on at full volume and also the style volume with it. I have no problem with any other voice on the keyboard.

If I quickly move the volume pedal it reverts to normal volume but not before it's damaged my ear drums.

I have done a system reset which made no difference. The SD7 is midi'd to a Tyros 5 but it still happens if I play the SD7 direct. What I find strange is it's the only voice with a problem. All other organ voices seem fine.

I know I can revoice the offending styles but I like to play the built in styles and match a tune to them when they start so it's difficult to remember which styles have B3 Over contained in them.

Hope this all makes sense.
