(Dai commenti) "one reason this etude sounds like 8-bit music is the alternating voices. early game consoles had very few sound channels, so composers used a kind of "voice stealing" technique – rapidly switching multiple voices on a single channel to simulate more voices. this piece does something similar: it's mostly just 3–4 notes at a time, but the rapid alternation makes it sound much bigger." https://youtu.be/rQ81jzlR...
