Silksong of Silksong : )
Pure MIDI visualization. I've been practicing a piece from Agnia's piano score recently (it's quite difficult, the transcriber really showed off a lot of technical skills). So for posting content, I've been directly visualizing the MIDI of the scores I want to play. Otherwise, I would have preferred to play it myself first before sharing.
