If you want hardware, it's the creamware B4000 Organ module you'll need. There's hands-on
drawbars, etc... It sounds exactly like a B3 (with a leslie), even emulating worn
keys/tuning. It's modelled rather than sampled, which is a bonus, of course.
I've used the virtual version for a while, now, and it sounds great. The hardware
version has all the drawbars, etc...
You'll need a midi keyboard to go with
it, of course, but it's possibly the best gigging solution.
