Narrative:
During descent into sju, controller advised we were east of course. Leaving fll, ZMA had cleared us direct to roble which was entered in the gfms, but apparently, I did not ever select auxiliary navigation on the autoplt mode selector. We were reclred to beano and made the crossing. Word to the wise -- rechk all switch position when a direct clearance is issued.
