@STMusicBot Wow. This is pretty impressive sounding but It certainly does not sound like the ST sound chip.
I assume it's just sampled or is it some type of .mod player?
@Judeau @STMusicBot All these files are real ST/AY code running on a player (specialised emulator) which converts them to an audio file.
I don't know the particular specifics of this file but I can tell you it really is an AY sound chip producing it (under emulation).
