<HTML>I have been taught (and it says so in the regulation manuals), that the rep springs should be adjusted so that there is a "gentle rise," when you let up on the key. This winter I regulated all of the main pianos in the school, including the piano faculty pianos, with the rep spring set to give me that "gentle rise." Now, all of a sudden, piano players are complaining about poor repetition, and when I check out the pianos, there is almost no rise at all. Once upon a time I heard that the springs will change with the change in weather. But what is happening? How come all of my rep springs are flat? Inquiring minds want to know. Wim </HTML>
