MiniMens piano string simulator introduces the new "contact ratio" =
parameter for analyzing the break in the scale from blank strings.

Contact ratio means contact time of the hammer with the string, divided =
by the time, the wave needs to run from the hammer to the bridge and =
back to the hammer. If the time is equal, the ratio becomes 1.0, what =
means that the hammer is in a synchron movement with the string. A lower =
contact ratio will produce a more partial pronounced tone, whereas a =
higher contact ratio increases the losses of the higher partials.

 (the last blank stringed key  is F-21, speak. length 1475 mm (58 inch)
