The VB3 is okay, so is NI I have both but don’t use them unless I have to. The VB3 sounds better to me but isn’t 64bit and I could never get it to work w/o crashing cubase. Maybe someone else has had better luck and also on website they say they have no intention (paraphrase) of going 64
This is just opinion but…There is Nothing (!!!) like the real thing the clone software just doesn’t do it for me. I also have tried 2 Leslie emulation pedals, one the Mini Vent and the other via Hammond/Leslie. They are both really well done pedals but the Ventilator is very gritty and would work great on a rock project out of the box. I imagine with a little tuning to it the Vent would work good for Jazz also. The Leslie I think is not much different than what comes in new Hammond organs…The Vent has Lots of beef. I tried those on a Hammond VK3c
