Alain,

It seems that you have had the best gear arranger keyboards you can get (SD1, 9000Pro, KN7000).

Like me you'd probably want to buy some new revolutionary gear that would change the way you make music. Thing is, you'll never be 100% satisfied or happy with just one keyboard. Well... same goes with someone who has 2 keyboards, and the person who has 3 KB's and so on...

I guess gear fetish is costing us lots of money, but some of us (like me) see that it's all worth it to have the best technology has to offer.
