hardware = full compliment pots, switches and leds, 5V/3A lin reg, standard two line LCD etc etc … chips etc built on single piece of plain perf board.
I don’t assume any fault folks, as all is fine. Its juat that I expected to see MIDI activity on the display without connecting box to MIDI-games port.
MIDI non connect:
Apply power to app.
LCD shows only the standard (undriven) blocks of graphics.
