I purchased this in the hope that it would replace my hardware Bass station rack. My very first impression was that it did indeed sound like a BS. The dissapointment came when I loaded some sysex patches from my songs and sustituted the plugin for the real thing. The patches sounded quite similar but not quite right. As a test i began creating patches on the hardware and then transfering to the plugin. They were never quite right. I thought it might be the transfer process, so I tried to manually create the same patch on the hardware and Plugin. It was never quite right. Static patches with no movement were close enough. Dynamic patches sounded much better on the hardware (I have had my BS for 9 years so am very familiar with the sound and programming). When you sweep the filter on the hardware the sound passes through various timbral changes that give you that goose bump effect. The plugin is linear and lacks the organic beauty of the original. I would say without hesitation that the plugin is clearly an inferior sound source to the original. I am not nit picking either, the difference is clearly audible and if the original had sounded like this I don't think it would have reached the classic status that it enjoys. It has it's uses but is a not so close second place to the original.
