SoundFonts.it has updated VB3 to v1.1. This new version is a complete rewrite and brings many major improvements since v1.01, plus some new features like a new "9 key contacts" simulation and 2 sets of drawbars per each manual.
VB3 is a virtual tonewheel organ which simulates an american electromagnetic organ of the old days, but it's also capable of other simulations like the italian transistor organs of the seventies or the red-tolex organs played by famous pop bands of the sixties.
