Glenn, yes there are improvements but not $99 worth. There are more adjustments you can make and more setups. They include emulations of more speaker cabinets, i.e., not just the Leslie Speakers. I would say there is a slight improvement in the quality of the sound and effects (chorus, distortion & reverb).

Plus there are some bugs as noted above. It shows up in my soundcard mixer window as peaking into the red and yet there is no sound at all coming from the speakers for some of the setups....needs to be fixed. I should be careful what I say. It could well be the combination of my equipment and software that's the real problem...we'll see.
