--- Paul Dempsey wrote: it seems to me that having a special,controled room might have problems of its own. If it is stabalized in the room, what happens when it is rolled onto a dry or damp stage for a recital or concert? Certainly the piano would immediatley begin to become unstable again as it either drys out or starts soaking it up. That might create performance problems,extra work,etc. Likewise, after the performance and the piano is returned to its storage area it would change again. --- end of quoted material --- Thanks, Paul, that point is well-taken. That is why I mentioned that I intend to also install a DC system under the soundboard, probably with three reservoirs and a number of rods. The DC system should act like a buffer as it adjusts between the two spaces, and should prevent sudden changes in the board. Unless the piano is away from its storage space for more than a day or two, I doubt there would be a problem. Also, my understanding from previous posts on the subject is that room climate control systems are limited in what they can do, under severe outside conditions. For instance, here in New Hampshire it commonly goes below zero in the winter. Room or building humidifiers are designed to cut off at a lower RH so that condensation doesn't happen in the walls. That means there will be less of an extreme in humidity between the climate-controlled studio and the uncontrolled concert hall (perhaps 15% difference). Does anyone else have direct experience with this kind of storage arrangement? All comments appreciated. Danny Dover,RPT Dartmouth College, Hanover, NH
