Lol. For once, contrary to the claim, this doesn’t sound like stepper music at all. And I guess all the programming is utterly unnecessary. At that point you could rip out the wires, throw away the driver you’re programming and just connect two wires from the motor to an amplifier. It’d do pretty much the same.
And is it just me or is that cheap AI narration in the video? I mean I don’t want to be negative. But I think this has exactly zero artistic value, doesn’t sound interesting (like a stepper motor or electric toothbrush does), and it’s a useless programming exercise when it could be done way easier and better without any of the limitations with samplerate and simultaneous sounds.
