He's settled loudly on Milan - may change (6,3)

'he's settled' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'loudly on milan may change' is the wordplay.
I cannot quite understand how this works, but
'loudly' could be 'f' (short for forte - 'loud' in music) and 'f' is present in the answer.
an anagram of 'may' is 'yma' which is within the answer.
an anagram of 'milan' is 'amiln' which is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
