Everything was sample based then. I, of course, used B4 when I found it. I was using Roland jv 1080 module at that time. Then, like many others, fell hard for VB3. Just look how long it took someone to produce a decent Leslie. THAT is the Hammond sound. All the sampled organs really sounded great, but the rotary was substandard. VB3 changed the echelon for developers, and it took quite a while to get near what GSI was dominating.
