Retro "video game" music, and many emulators and VGM players, have a similar (analogous) issue; using very high-quality (perfect) or very low-quality (exhibiting digital aliasing) square and sawtooth waves... and lots of them sometimes. In reality you had a very small number of fixed-function analog voices (= no digital aliasing) which were run through a cheap lowpass filter (= not perfect) on their way to the RF modulator.
