Can this tech be used for making powerless keyboards? As in no power just a mic.

  The processing required to process the signal, combined with the decreased precision wouldn't make it very practical, in my opinion.

  This is a cool idea. Maybe you could make a keyboard specifically designed for this which made distinctive tones for each key like a xylophone. That would be a fun project.

  now i'm imagining a keyboard where each key just smacks a piezo crystal

    Before I owned a house I had a little Phillips puck-thing with four piezo buttons that you could bind to different smart light presets, no battery or wiring required.

      Ah, you've reminded me that there was an early zenith tv remote that was literally just chimes https://www.theverge.com/23810061/zenith-space-command-remote-control-button-of-the-month https://www.theverge.com/23810061/zenith-space-command-remot...
