I need help, I have a project for an electric drum, I'm using 27mm piezos, 1Momn resistors and 5.1V Diode Zener, and a Multiplexer, I'm having a problem with one of the pads, where I hit it and it returns the sound it, but with an extra sound from another pad, I've already changed the sensor, I've changed the Arduino channel, I also checked the position and it doesn't touch the other, I came to the conclusion that the problem is in the code, I'm using the MIDI.h library and Hello Drum, can anyone help me?
/*
EXAMPLE - MUX Sensing
With this sample code, you can make 16 single piezo pads with a 4067.
