Prototyping a Midi to CV module with more functionality than existing offerings

Note that 6N138 is not a great choice for MIDI (though it’s commonly used anyway).

6N138 is a JEDEC part code so they all have the same basic specs. Just grab one in the right package (DIP/PDIP for through hole, not SMD). Note that 6N138 appears in a lot of internet schematics, but strictly speaking it’s not fast enough to match the MIDI spec requirements, even if that probably doesn’t matter for normal use. (I use 6N137 instead, which is much faster, has a logic gate output instead of a darlington transistor which is nice since you’re connecting it to a logic gate input, an…

Verify you have the MIDI connector pinout right, it’s easy to get it mixed up and it’s described incorrectly in some places.

The big long ICs are a stand-in for a Teensy 3.2.
