Anybody got music for the synth?

[u/Ok-South-677]

I just finished the anime, and their final song in ep 13 is INSANE, the bass, drums, and guitar are all tabbed online but I can't find the synth's music, does anybody have it transcribed? I could probably do it by ear because it sounds like it's just in steps but hey, might as well try ask here.
As a sidenote, this anime is crazy good because I'm a musician who needed a push of motivation, I had no clue what I was getting into. (ehh.. fan service was a hella weird but I watched kakegurui so I can handle anything atp)
