To All- I was in charge of several concert instruments that were kept in a storage room under precise environment control. However, the auditorium in which the instruments were used saw humidity fluctuations between approx. 20% and 75%. Bringing the instruments (kept at 45%) into the auditorium almost always precipitated big changes in tuning and regulation. I preferred that the instruments be kept on stage at least a week prior to their use to acclimate. This probably negated the rational for keeping the instruments under humidity control while in strorage because they not only had to make the adjustment to the stage environment, they also had to go back to storage (and 45%) after their use. For the popular instruments, that meant going back and forth many times per year.
