Thank you Terry, That precision : "different pianos, different solutions" seems very appropriate to me. Another question : Do many agree that a small external humidifier near the piano will help significantly in adding some humidity to every part of the piano when needed (soundboard and pinblock and action, in a grand piano), albeit as a second choice to whole room conditioning ?
