Music Synthesizer

Inspiration: From classes I've taken in the past, I wanted to design a better version of a color organ I have made in previous classes. As a result, I thought about designing a basic music synthesizer.
Goal: This music synthesizer should be able to play music, and have a corresponding LED display going along with it.
Description: The board is powered by a 9V barrel jack and voltage is stepped down to 5v and 3.3v for the onboard electronics. The ESP32 processes voltage inputs, data input (music) and controls the LEDs. The user interacts with the board through potentiometers and buttons.
Block Diagram of Project: Should be able to take user input (buttons + potentiometers) to toggle audio output and LED output.

Completed Layout (Above)
Current Board Status (Below): Notice that the trace from the USB to the ESP is stripped - due to an accident.
Edited Board (Above) : Potentiometer footprint orientation flipped.
Final Incomplete Board (Below): Some of the LEDs light up, sometimes the port gets recognized which is good news for future work.
