PianoSens vs PitchGrabber with High Noise

The method is correct for the prior videos that put the PianoSens sensor in a head to head test with the PitchGrabber. Here we use a deafeningly loud Ninja grinder right next to the piano. We record the audio from the screen recording of both devices with normalized gain settings each at -3dB below full scale, just like a pro recording engineer would do. Listen to the result! The PitchGrabber drops out after a couple secs due to the app's inability to distinguish noise from signal., whereas the sensor continues to read more than 10 secs after the attack with no pickup sounds of the Ninja grinder.

I love these kind of real world tests

Seems like a fast Fourier Transform that snaps amplitudes to their nearest note frequency. Pretty neat!

Haven't seen something like this before. Can this be used to turn a normal piano into a MIDI input device?

[@PianoSens-ey8jb]

I haven't really thought of that, but it's possible! It reads string movement and produces the sound from the strings, which is the input into the soundboard of an acoustic piano.

Sure thing. I'd consider making a CASIO DG-20 (MIDI guitar) kind of instrument with such system in place.
