Dan, would it be possible in future to do more than the intro, a couple of bars of only one Variation and the Outro..?
Without a couple of chord changes, and a fill to a new Variation, it's kind of hard to hear how successful the translation, and the overall vArranger is actually working. Those transition points are usually the place any weirdness tends to show up.
