I purchased it when it became available as a 64bit vsti. I think it is one of the better/best vsti ones but I still can't find any VSTi's that competes with the Organ sounds in my Korg Oasys 76.
Unfortunately, I know the day will come when the Oasys will take a **** and that will be that so I have been looking for a replacement in a vsti. No luck so far.
I have not had any issues using VB3 64bit so that is a positive and the price was right...
