When the game lags on client-side or server-side midi tracks become desynced for the rest of a song, and becomes more and more noticeable on songs with great amounts of tracks.
The easiest way to reproduce it is to play a midi with 10 tracks+; but, you can also intentionally lag the game out to cause it as well. It becomes more of a problem on larger modpacks due to instabilities.
Of course, the expected behavior is for it to sound good; but constantly resyncing them would probably be taxing on the network so I'd recommend resyncing maybe after each bar or two.
