ESP32_S3 Boards and BLE-MIDI

[jhsa]

Hi guys, There is still very little information about these ESP32 S3 boards. I got one to test and I think I can confirm this library is working with the I have. Here is the sketch I used to test it.
Button on pin 4 and GND. When pressed it should send Program Change and Control Change messages, as well as toggle the LED.
Receiving Program Change 10 on any channel will turn the LED ON.
Receiving Program Change 20 on any channel will turn the LED OFF.

This is an example of how we would use basic midi in and out in real life when building midi controllers. Some examples do not show that.
I hope this helps.

To the project owner. If you want I could post a couple more real life examples ;)
Thanks for this amazing library.
