How much control do you have with the solenoids, and the hammers? Is it just control of the velocity of strike, or is it possible to have positional control of the hammer?
If you could control the position, maybe you can create some interesting tonal effects that a human pianist could not achieve, by holding the hammer close to the string to partially damp it

(Similar to what guitarists can do)
