Cool enough I suppose, but the framing had me expecting the more farty twisted squarenoise instruments like in Wario Lands 1-3, and less smooth sines and squares. I tried out Kimi No Shiranai Monogatari and Daft Punk's Aerodynamic.

Maybe you could list examples for midis you thought sounded cool next time you share this, or in a comment.

Edit: though I guess a huge part of Wario flavor is the dissonant intervals in the music, as much as the farty instrumentation.

Better MIDI search: <https://bitmidi.com/> I guess you could copypaste the 12345.mid id number into the Wario Synth URL, but it's a bit tedious.
