When you hit your e-drum snare pad, the piezo picks up the “shock” and generates an electric signal.
I try to explain it in a very simple way and I hope this text will help you to understand it once and for all. Understanding MIDI is necessary to be able to work with sample software like EZdrummer, Superior Drummer or Addictive Drums, for recording or just to enjoy the high-quality drum sounds while playing e-drums. There seems to be a lot of confusion on how it works and how to use it. One of the most popular questions on my channel and website is: “How does MIDI work?”.
