I agree with Donny. Your own ears have to tell the story...
My taste tends to gravitate toward the sound of a rock organ ala Keith Emerson playing the C3 he used in the 70's. To someone who wants that perfect "jazz" organ sound my tastes probably mean absolutely nothing.
Of the following recent boards I have owned or have played specifically listening to organ sounds, this is how I might rank them for my taste: Of note also, I have heard the B4 software demoed and none of the boards I list here came close to it. Like starkeeper I have heard nothing but positive feedback on it.
1. Roland VK760 - pretty darned good. If it were a little less expensive I'd buy it... Think I'll buy the B4 software instead just to emulate organs with in the studio.
2. Korg PA80 - good but not really in the same class as the VK. Good enough for live work though that I'm not spending the extra bucks on the VK or a laptop for the B4.
3. Casio MZ2000 - one of the best sounds on the board. Maybe better than the PA80 , but I can't remember for sure. I liked it far better than the PSR740 I had at the time. The day I bought it I played parts of karn evil 9 by ELP on it. That sold me.. Not sure if the new wk will be as good, but the current WK's are nowhere near it.
4 PSR 2000 / 740 - Fair..
5: Motif - has some other good organ patches but the rock organs are the least impressive patches for me on the whole board.
6: Roland Fantom / Fantom S. I would never use it for a rock organ sound.
There it is..just my opinion and pretty much useless if your ears want to hear something other than what mine want to hear.
