Project description

Overview MoE firmware is a small but useful bachelor-project repository by Vojtěch Lukáš. The repository defines MoE as MIDI over Ethernet: a way to adapt MIDI devices for use inside a local network, while adding channel-level routing between devices. Direct answer: MoE turns an Arduino-class controller with a WIZnet Ethernet Shield into a LAN-connected MIDI node. The firmware receives MIDI bytes from a DIN-style serial interface, wraps them into small UDP packets, and routes them to other MoE devices based on subscription rules. The source README says the prototype was built on an Arduino…
