### TeensyUSB code ### Refer to [Teensyduino instructions](https://www.pjrc.com/teensy/teensyduino.html) to set up the development environment. When compiling using Arduino IDE, remember to set the mode to **"Serial + MIDI"**. Note: the "Serial + MIDI" mode was [added recently](https://github.com/PaulStoffregen/cores/commit/a480cd28da49406c297d241a3cbb535e83bec7eb) and as of this writing is only available in the [beta version of Teensyduiono](https://forum.pjrc.com/threads/34472-Teensyduino-1-29-Beta-1-Available). Also check out [this template](https://github.com/apmorton/teensy-template) for using make and a text editor of your choice for comiling TeensyUSB code.
