@k-okada I had my pip installed pygame and the version was pygame-2.0.1. If I remove and reinstall pygame by pip uninstall pygame && sudo apt-get install python-pygame, then import error disappeared.

So pip was the cause in this case....

Also I check with/without MIDI device by using python-pygame from apt, so having MIDI device should not matter.

I see, so proposed workaround is to remove pip, not run sudo ln -s
