Yes,the backing on the song is from the Motif. It's all Arpeggio driven and it was not very difficult to create. Actually quite easy and fun. Just pick a voice and then select from thousands of styles of intelligent arps (arps that respond to how you play), play and listen. Repeat if not satisfied. Do that for each backing voice (Drums, Bass, E Piano, Guitar, Strings, Pads). You can create a four part backing in a few minutes. It does take longer but only because there are so many arps to choose from. The lead piano, Trumpet and Sax are from the T3.
BTW, I have done something similar to what Diki suggested. I select a Tyros Style, then mute the Drums and Bass. Then I select a Drum and Bass voice on the Motif with appropriate Arps and I have a Tyros Style with Motif Drums and Bass. Really improves the sound of the Style.
