Hi Fran
Not impressed with the piano or sax voices used, and I also thought the B4 sounded a touch harsh, the style seemed fine for general use, not as sophisticated as Tyros 2 but they can sometimes be over the top.
Overall for an off the cuff (So to speak) performance it seems fine.
BTW you will find that for backing (And a lot of solo work) Akai samples will be as good as any. (The advantages of High End VSTs tending to get lost in a mix)
Look forward to some more songs, particularly when you’ve got the Mediastation optimised.
