Its not just you Col, it happens almost everytime. Although in this case, perhaps Leezone was a little over enthusiastic with the thread title

The thing is, you don't see it the other way around. If someone posts a demo or recording of their Korg, owners of other keyboards do not jump on the thread and claim their arranger will do it better. I find it very strange.
As for the youtube video posted here - I enjoyed it a great deal, and its refreshing to see an arranger keyboard put to use this way instead of in a retirement home! Its a nice clean recording with great vocals.
