Process not started

I got this when I tried to listen to the MIDI device (followed the example):

** (stop) exited in: GenServer.call(PortMidi.Listeners, {:list, #PID<0.148.0>}, 5000)
    ** (EXIT) no process: the process is not alive or there's no process currently associated with the given name, possibly because its application isn't started
    (elixir) lib/gen_server.ex:729: GenServer.call/3
    lib/portmidi/input/server.ex:35: PortMidi.Input.Server.handle_cast/2

Last message: {:"$gen_cast", {:new_messages, []}}
State: #PID<0.149.0>

My statement:

iex(1)> {:ok, input} = PortMidi.open(:input, "KRONOS KEYBOARD")

Did I miss something?

Hey there, thank you for using ex-portmidi! Are you absolutely sure you have added the portmidi application to your mix.exs file?

def application do
  [applications: [:portmidi]]
end

Looks like the PortMidi.Listeners GenServer (which is started with the :portmidi app) is not running.
