Irritating engineer capturing violinist's heart (6)

I believe the answer is:

riling

'irritating' is the definition.
('rile' can be a synonym of 'irritate')

'engineer capturing violinist's heart' is the wordplay.
'engineer' becomes 'rig' (I've seen this before**).
'capturing' indicates putting letters inside.
'heart' indicates the central letters.
The centre of 'violinist' is 'lin'.
'rig' enclosing 'lin' is 'RILING'.

(Another definition for riling that I've seen is " Irritating, needling".)

I've seen this clue in The Independent.
