Hi, I wanted to check out this project but I couldn't compile it. This is the error I got:

could not compile dependency :portmidi, "mix compile" failed. You can recompile this dependency with "mix deps.compile portmidi", update it with "mix deps.update portmidi" or clean it with "mix deps.clean portmidi"

Thanks
