bothering me right now

IDK if this is the right topic… but I could’ve sworn someone composed an auditory illusion type piece here in Notessimo. An auditory illusion is like this: https://youtu.be/A7lODxnCcmo
It was done all in piano and it sounded freaky.
Does anybody know what the song was or who did it?

oh yeah. drago made something like that on v3, but with triangle wave #1, not piano.

that’s it! THANKS
