Here command history:

  368  cd mpd_oled_moode_audio_copy_scripts/
  369  sudo bash mpd_oled_moode_audio_copy_install
  370  sudo mpd_oled -o1 -c alsa,hw:Loopback,1
  371  ps ax | grep mpd_oled

I have just noticed that the ps command shows you are running 'mpd_oled -o6', while your screen appears to need 'mpd_oled -o1', so this will also be a source of problems.

Started with 
sudo mpd_oled -o6 -c alsa,hw:Loopback,1

Still no graphic eq bars. Raspbery is the 4th. Equalizers is enabled with flat.
But i cannot see bars
