Dear Mal,
let me disagree..... with kindness, of course.
I used to have an Hammond L122R with 142 Leslie cabinet: two jewels. So, I have not easy expectation for Hammond sound emulation.
For many years I had various Korg flagships, and i could never get a decent hammond sound.
Then I purchased an Hammond Xm2-Xm2c module (with real drawbars) with excellent sounds and Leslie emulation. That solved the problem (Unfortunately Hammond does not produce anymore this module).
Therefore, when I purchased a Clavinoca Cvp309, and lately Genos, I thought i should use my Hammond module.
But.... with big surprise, after quite a long search on the Clavinova (but it is exactly the same on genos), I discovered an effect that give a surprising depth and majesty to the organ flute sounds. I'm talking, for Genos, about: insert/Legacy/Rotary Speaker 5 (you must go on page 32 of the legacy effects).
Try this effect with the Classic (A whiter shade of pale) setup 688600000 + Perc.4 at level 6, very effective both with slow and fast Leslie.
Or, if you like smooth jazz organ (like Earl Grant played American Classics, with slow accompaniment), same effect, setup 888886443, no percussion, Leslie fast, also (for more full sound) with Block Harmony.
To better explain what kind of sounds you can get, you could listen to this my example (done with Clavinova Cvp309; but it is just the same with Genos):

Hope to get your welcome comments,
