The ESP32 Audio Kit V2.2 is a nice platform for synthesizer projects and also other stuff.
Unfortunately it has limited available IOs and there are also issues when trying to use them for SPI, I2C.
I've seen discussions online to connect for example a RFID reader to this platform.
In this video I would like to show a possible modification to free IOs for I2C, SPI and also fix the issue.
On GitHub you will find some code soon to get the button states (key1 - key6).

Please feel free to write your ideas into the comment section below. I am very happy to get feedback from you.
Do you also use the audio kit? Do you consider using an analog input to connect some buttons?
