Smooth member facing action on a regular basis (6)
I believe the answer is:
legato
'smooth' is the definition.
('legato' can be similar in meaning to 'smooth')
'member facing action on a regular basis' is the wordplay.
'member' becomes 'leg' (I've seen this before).
'facing' is a charade indicator (letters next to each other).
'on a regular basis' means one should take alternating letters.
The alternating letters of 'action' are 'ato'.
'leg'+'ato'='LEGATO'
(Other definitions for legato that I've seen before include "Got ale (anag.)" , "Smoothly flowing (music)" , "scored smoothly" , "play on without pause" , "Played smoothly" .)
