Ken,

Though I suppose it's not a bad practice to slightly depress the keys, on a
QRS system it is not necessary so long as the installation was done
correctly.  When installed, the solenoid plunger has a small amount of space
between it's tip and the key bottom at rest.  PianoDisc systems are another
beast and do require this step every time.
