Dear Beakybird,
No problem friend. First of all, I want to thank you for spending the time to detail the difference between the two keyboards. Yes, you were expected to list everything 100% and no where in my post implied that you should only list some of them. My post is different than yours and has completely different purpose and different perspective. Your post lists all the features. My post simply comment on these features.
Some of those who are looking for recommendation, simply need the feature list. But others they might need more. I found out by talking to people that sometimes they want to know if this feature is useful, needed, or worth the extra money... so on and so forth. My post was simply that and of course from my own opinion and from my own perspective.
I have tested PSR740 and PSR9kpro. In my opinion, I found out that PSR9kpro is overpriced. Yes, I do like the extra features, but it is not enough to justify 200% price increase over PSR740. Now most people disagree (and some very strongly) with me and that is fine.
If I want to get a recommendation about a keyboard, I would like to hear both opinions: why this feature is not worth it and why it is worth it from totally different perspective. Mine was one of those perspectives.
By the way, I made a case for PSR9Kpro in terms of the harddrive, ram, and better sequencer.
Cheers
