This sounds as near to a Hammond B3/C3 as I'll ever need, and I used to own a real one! Easy to find a good blend when recording, and plenty of tweaks available for the inbuilt Leslie simulator. Nearly every control maps directly to my GM Lab D9-X drawbar controller. The only one that doesn't is Percussion on/off, which uses a different cc number. There are plenty of ways to get around that, but you can't change the cc mapping in the Waterfall B3 Native, so that's my one, minor criticism.
Aside from that, this virtual instrument is perfect for my needs and great value.
