Ah, the good old AY-3-8910 / YM2149, as used in ZX Spectrums and Amstrad CPCs, where it should have stayed!
Any sound you like, as long as it's a square wave!
And yes, using the "out of the box" features of the soundchip, e.g. not cheating by using the CPU to drive the sound generation, the good old SID of the C64 was far better.
I remember being very disappointed when upgrading from a Spectrum 128 to an ST and discovering the in-game soundtracks at the time (late 1988) to be identical. Only had the ST for a year, before getting a computer that could generate
decent music!
