Regulation question

[David B]

This is a question about let off on a grand. When one depresses the keys, and holds them, should the hammers all fall back to the same height after they have hit the strings? If they fall back to different heights, will this have any effect (like on the repitition)?

[Barrie Heaton]

if you depress slowly they should not hit the string the should set off then the drop screw will drop them to 3mm depending on the makers specks

this should be even if it is not then the regulating is uneven and yes it will make the repetition uneven
