Unfortunately paid overs to import soft object (10)
I believe the answer is:
disapprove
'object' is the definition.
(to object to something is to disapprove of it)
'unfortunately paid overs to import soft' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'to import' is an insertion indicator.
'soft' becomes 'p' (musical abbreviation for 'piano').
'paid'+'overs'='paidovers'
'paidovers' is an anagram of 'disaprove'.
'disaprove' going around 'p' is 'DISAPPROVE'.
(Other definitions for disapprove that I've seen before include "Hold an unfavourable opinion (of something)" , "Reject" , "Not be happy with" , "Censure" , "mind" .)
