Send MIDI from a DAW (without optocouplers and other electronic stuff)

Hi guys! I was trying to send MIDI to Arduino without connecting lots of electronic components and I did it. Here's a video where I show all the setup:

  1. A DAW (Reaper)
  2. Promidi and Serial libraries
  3. Processing
  4. LoopBe30 (to create Virtual MIDI ports)
