Put down some money (4)

I believe the answer is:

note

This clue is a double definition.

'put down' is the first definition.
(noting is a kind of putting down)

'some money' is the second definition.
(a bank note)

(Other definitions for note that I've seen before include "Pay attention to; record" , "Memo; tone" , "Short message; piano key" , "Tone of importance" , "Make a mental or written reminder" .)

I've seen this clue in The Irish News.
