Digital keyboard/piano--sensitive to heat, humidity?

If the sound production is purely digital, environmental impact should be minimal. If there are actual strings, hammers, and sounding board, the tuning characterists and requirements will be the same as a conventional piano. How the mechanical components are engaged has no bearing on their mechanical characteristics. We have a conventional upright, and it is tuned at least twice a year by a very nice old fellow who urges us to be yet more conscientious. Some freinds have a Yamaha Disclavier, which is similarly manually tuned on a regular basis.

I am able to notice a weather-dependent difference in "Sound" from either piano, as I hear both frequently.
