Very nice work! How does it (does it at all?) control how hard it hits from one note to the next? What does the striking - solenoids?

Yes, it uses solenoid based actuators. Not sure if it controls the dynamics too, but one way to do that would be by driving the actuators using a curve modulated by high frequency PWM; probably quite hard to calibrate to MIDI key velocity since those actuators are essentially on/off devices, but doable.

A very nice project, I'd love to see some more information about it.

Very cool - do you have a write up?

Magic!
