Yes, I wrote, arranged and recorded the work. It's my hobby.
The Violin is actually a GM Voice on the Motif XF. The accompaniment is not a style. It is made up of two Motif voices (Strings and Harp). With Motif you basically can quickly make your own "style". You select the voice and then you can choose from thousands of intelligent arpeggios for each voice. And you can have up to 5 different variations within a work. I used 3 for this work. So you basically try out a some these and find which ones work. That's it. The arpeggios respond to how you play and you have a variety of parameters for each that can change the behavior of the arp. The soft background strings you hear were from the Tyros as well as the Flute and Trumpet.
