Hi all.

I need to build a controller board that converts the signals from a keybed into Midi signals. I plan to use an Arduino Mega as the controller and I will write the necessary code for it.


I can figure out the scan matrix of the keyboard using a multi meter as it’s a simple signal vs no signal event, but how is velocity transmitted from the keyboard?

Regards
Sharp.

Usually the time between closure of the first and second of the pair of contacts activated by a key.
