This tool is used on my Raspberry PI Zero W based pedal, that controls a Zoom B3 pedal via MIDI in conjunction with https://github.com/bennigraf/zoomb3ctrl. This tool basically acts as a bridge to display the patch names to a 8-digit 14-segment display (bought here).
It Listens on port 3024 (tcp) and prints received messages that 14 segment display (driven by a HT16K33 driver chip).
