Any downloads from now including the free downlod is at 1.01 so you don't have to update.
I think the GUI is horrible actually and it amazes me how bad some people are at designing GUI's. They have no idea. Simple as that. Having said that though it is a great plugin for sure.
Eddie I agree with you. There is a WIDE switch but not sure what it is doing. From what I can see there is no panning on the top and the bottom delay which is a major oversight for me. I don't think you can store settings also which is a bit dumb as well.
The only option you may have is to set up two of these and pan them accordingly. It just means more compliacted setting for two of them instead of one. But you could also set the threshold full up one one so only the bottom delay is working and fully down on the other so the top delay is working on that.
The free Groove 3 tutorial on this is well worth watching too.
