just to clarify:
1) the Vox Humana stop is a reed stop.
2) the thing that on most organs which mechanically pulsates the air stream,
as you mentioned, is called a tremolo, and it can of course be turned on and
off. it usually works on a whole division, such as the Swell division. It
can be that a Vox Humana stop is part of the division that has a tremolo.
3) The rank of pipes tuned slightly out of tune to cause beats is called a
celeste.
