MidiMallet with 40 piezos

Hello All,

Im very new to all of this. I am building a midi mallet controller, and need help with the electronics. the arduino needs to connect to 40 piezo (built into the bars, just have leads exposed), connect to my laptop running logic pro x, a midi in/midi out, usb, a sensitivity knob to control how much force is required to hit each bar.

Please help!

Thank You!
