So I've built the whole electronic scheme according to the plans. I'm using a Pi 2, the circuit with the optoisolator, and I've tried reversing the leads between the two pins on the midi plug. But I cannot seem to get the old school midi working, just the usb midi. I've tried to change code through the Pi CLI and nano but I get errors such as "no such file or directory" when I try to open folders. Anyone have any input?
