    It's feasible, but there's a little lag/delay that may not work well for you when using frequency detection and converting to midi data. I have indeed done this myself with aTeensy 4 and find the...

    The digital output of the sensor is not audio data. The audio shield is attempting to convert data that is no longer analogous to a pickup. This is why you are hearing a "metallic" noise.
