SunVox is a modular synthesizer + tracker, and each module by default has its own little oscilloscope, which can be configured to represent sound signal in many ways: as a normal music player (dots, lines, painted areas etc) or as a "real" oscilloscope, like the stereo phase scope mode (beginning is sunvox software OC, then a real hardware OC for comparsion, very beautiful) or XY mode (similar).

you know what it means. yes. again. 🍎

the old guy is pretty talanted actually and makes a lot of covers on his channel
* touhou stuff (as in this video)
* minecraft, persona, undertale, gayshit impact and other games
* anime, like toradora, bleach, komi-san etc.
* folk songs
and a little bit of classical pieces of course
check out if interested! his channel is rather unpopular despite hundreds of videos, most of which are cool
