ESP32-Midi-Controller (Single OLED Version)

Midi Controller with Expression Pedal
This controller was built to control VST plugins in Reaper.
It uses an ESP32, 10 footswitches, 1 expression pedal.
It connects to the computer running the DAW via the RTPMidi protocol.

Note: This branch is an older version of my controller. I've since updated it with support for multiple OLED screens and switched from wireless RTPMidi to Midi over serial/usb. Please check the other branches in this repository for those versions. I'm keeping this branch as some may prefer the wireless RTPMidi and to only use one OLED screen.

1. Single-OLED RTPMidi (wireless) version
   
2. Multi-OLED RTPMidi (wireless) version
   
3. Multi-OLED HairlessMidi (wired) version (Version I currently use)
