• NOTE: The more standard way to build midipix these days is to use this shell script that someone else made https://github.com/lalbornoz/midipix_build
• NOTE: I have started working on PKGBUILDs here: https://github.com/DavidEGrayson/midipix-packages

Getting started with midipix

Let's compile midipix from source and play with it!

1. Get access to a Linux machine for development.
2. Install git and gcc on the development machine.
