I was looking for a replacement for Organ One, which has an amazing,'pure' sound, but it kept cutting-out at higher frequencies. After trying several others, the B3x is the one I've ended-up using. It has some lovely 'clean' organ sounds and some lovely 'dirty' organ sounds, which you can combine, for added depth of sound. If you're looking for a virtual organ that's a cut above the rest, then this could be the one.
