Midi Keyboard Key Velocity Example

[RandyRyanG]

Would be very helpful to have an example sketch to add Keyboard velocity for a midi keybed that has 2 switches per key. That would measure the time from one switch to the next and then convert that measurement to the correct velocity.

1. Key1 switch1 activated = start time
2. Key1 switch2 activated (pressed harder) = stop time
3. Calculate time from switch1 to switch2
4. Convert time difference measurement to velocity
5. Send Midi Note on Event with measured velocity

I have posted this question on the arduino forum in less detail and I received response from @tttapa
