Midi expander

[elroy-croyden]

Thanks for the squares and circles, awesome work. More a question than issue, I'm currently building the midi-trig adapter as a little standalone unit. I'm assuming the 5V would typically come from the Eurorack psu. Seeing as it's standalone I'm going to use a 5V USB wallwart, to your knowledge will that work?

Hi @elroy-croyden,

I draw the 5V directly from the Eurorack power supply. If your PSU does not provide 5V, you would have to add an LM7805 to the circuit.
