OS-9 only had the built in S$Tone command, or whatever it was. It did a single voice, like BASIC. There were wrappers written that could translate PLAY style commands into the appropriate frequency and duration, but it wasn’t built in.

An OS-9 driver that halted IRQs and played multi voice music would certainly be doable, if multitasking was not needed during the music playback.
