Re: Duo-Art Plays Too loud
By Craig Brougher

Pete has one of those problems that pneumatics won't fix. When the piano plays too loud on loud passages but soft on soft passages, that just means one thing: His valves are leaking. Probably due to shrunken pouches or maladjusted lifter buttons.

What happens here is that the player on low vacuum leaks badly because the tension in the stack isn't enough to "suck down" all of the valves tightly. So he raises the first intensity enough to tighten the stack valves. After that, it plays the first intensity just fine. But since the first intensity has been raised too high, it boosts everything exponentially after that, and by the time his piano reaches mezzo-forte, it's peeling the wallpaper off the walls.
