Arduino MIDI Patch Manager

This is an arduino powered, 4 channel MIDI patch manager. It allows "programs" to be saved / recalled across 4 midi channels. I was looking for a little utility to pick up a shortcoming of my Arturia Beatstep Pro. This will allow me to set one "program" per arturia pattern.

Code and a .PLT file for the case are on my github: https://github.com/billieblaze/ArduinoPatchManager

No real schematic, I wired up a pretty standard MIDI I/O schematic to the arduino, used an i2c LCD and hooked up a rotary encoder / pushbutton combo (with pullup) to some protoboard and piggy backed it onto an Arduino UNO.
