STM32 ADC is 3V, not 5V. |

Can you please post the full schematic you're using? |

Vcc of the multiplexer should be connected to +3V. On OpenDeck Mini it's connected to 5V because AVR is a 5V MCU. But wait, did you specify your custom YAML file? |

Next time, before you open anything, please:
Also, you have S2 connected to A9 on schematic, but in YAML file it says A6. |

I built a prototype with 5 pots, connected via a 4076 multiplexer, using a STM32F401CCU
What is strange is that at full rotation they show a midi value of 103, the voltage is 4.66v, it actually passes through 127 (4.2v) and then the midi value drops to 103. Every pot I tested has this condition.
One pot does not register, and it's not the physical device, I switch them around, Analog 0 does not register.
