I'm already impressed, Ian. Don't get me wrong. But I have heard demos by talented players on many other arrangers, that if they leverage the best the arranger can do, and stay away from its weaknesses, sound just as impressive.

Korg's do great smooth jazz. Ketron's pop dance beats are hard to beat, Roland's do some pretty punchy rock, none of them are dogs, IMO!

It still comes down to the style, more than anything, I feel...
