Great update, and kudos to Acousticsamples for giving it for free for version one owners. I had been running B5 V1 through my mini vent but will try it through the onboard sim this weekend on a relatively Hammond light gig.
Setting things up on headphones or smaller studio monitors sometimes leads me astray as to what it will sound like in a room through a PA, but up to now I'm liking the new Leslie sim. As Jim points out, there is a lot of room for customisation within both the Hammond and Leslie settings and the midi implementation seems to have been improved a lot.
Steve, those presets do not appear to be loading.

So many drummers, so little time.
