Midi Song Play Back With Yamaha Style …. Possible ?

[Nova227]

 Several weeks ago I was working with a an imported midi file that worked perfectly .When I activated the style play function on Sx900 , I was trying out different setting in the midi menu at the time )
I was sure that when the on board style started it  synced to the midi file following the chord structure of the midi file. But using the  style information like the Chord Looper function follows progressions .

  I thought that was interesting feature but today I can't recreate it.

Was I imaging things ?
