I think the original Helmholtz Notation for 440Hz/MIDI #69 is a′.

Just a variation of this kind of notation is ač.

In Scientific Pitch Notation this is A₄.

"It is designated A₄ in scientific pitch notation because of the note's position as the fourth A key on a standard 88-key piano keyboard. On MIDI, it is note 69."

And Jim wrote: ač,0,69,440.0000000000.

Best regard, Karl
