From what I gather, most of the SRX-07 organ patches have the Leslie sampled into them, so you can't get the ramp up or down effect, just switching.

And, of course, if you run a slow Leslie'd sound through the Leslie sim in the MFX section, it sounds VERY weird...

I think most of tis comes from the fact that Roland had a VERY poor Leslie and scanner vib/ch sim up until recently, so they just sampled it instead. Trouble is, now they have the VK sim in most of their products, but the Hammond samples aren't straight, direct output ones...

Anyway, you want correct percussion behavior, you can't use samples... that triggering system just doesn't work right. You get the multiple trigger T-type sound, which AIN'T rock and roll, my friends!

To be honest, you CAN get the E80 Hammond beefed up a little... you just have to abandon your B3 drawbar settings, and do it by ear... That 5 1/3 is a little frisky compared with the B, and you have to remember that, if you have given your E80's Mastering EQ a bit of 'smile', it's going to brighten up the VK section too... I find it better (but more work) to just put 'smile' or any high band boosting on ONLY the sound that really needs it with the per-part EQ, and just boost up the low end a bit (which will help fatten up the VK section) with the Mastering EQ.

Don't forget about the leakage and distortion parameters, which can help dirty up that pristine sound a bit too...

If you are THAT much of a B3 fan, sadly, no sampled B is going to make you happy, much. It just sounds WRONG...
