You're not confusing me.
Yesterday musicbear also said its 3 notes, but also because of Sonic Visualizer, we know its tree notes.
Why do we, including me hear something else ?
I think it has to do with the fact its a bassguitar, and the way that especially the first note ( string ) is touched.
I might also be something like delay, that keeps confusing us.
My current bassline has two rows on notes. Top row is moved 1 or 2 /192 to the right.
Nice try but it does not really sound right.
You probably want to have a look at sonic visualizer.

Its a program like audacity, but it can do some interesting stuff. There is a pic of it in this topic.
Somebody from Linux musicians forum, had put The party - Kraze into the program.
The program can give a piano roll like picture of the notes played.
This tunnel remix, might also help you to hear its 3 motes, with first note longer.
( with according to the linux mucisian forum, ping pong delay added, for the tunnel sound )
Music bear also helped me with first piano part. It was close but no cigar.

A little change on the second bar of the loop.
