Easter Eggs and Running Jokes
Throughout the ages, Online Sequencer has had several April Fool's pranks and miscellaneous easter eggs.
Notable Jokes
Megalovania
Megalovania is actually a song that Toby Fox wrote for his first game, the Earthbound Halloween Hack aka MOTHER 4: Cognitive Dissonance. It's used for the final boss, Dr. Andonuts. The song was then reused for Homestuck Vol.6, but it's usually known as the song that plays in UNDERTALE when the player fights Sans during the genocide route. This song is pretty much a running joke anywhere, but what makes it so special here is when a user tries to say the name of the song in chat, it'll get censored. This is probably because someone started a chain with the song title or because of the unreasonable amount of sequences there are on the site that are just transcriptions of the song.

i created the arp at the beggining with sitar
This is a meme that originated when user Legendary_ posted Space Travel and left a comment on his own sequence reading "i created the arp at the beggining with sitar" which sparked a meme where ♩♪♫♪♬♩♩ (now banned) posted the comment on nearly all of Legendary_'s sequences, and a chain of comments on the original sequence. There is now a playlist and a forum post containing sequences making fun of the meme.
Get the vaccine
On August 14, 2021, Benvisions posted to the chat "We should all get the vaccine. Safe and effective." He used inspected elements to edit the Online Sequencer title and subtitle from "Online Sequencer: Make music online" to "Get the vaccine: Schedule an appointment online" to encourage users to get a COVID-19 vaccine to stay away from the COVID-19 pandemic. It later got pinged by Fox and subsequently added to Robo's quotes.
