The Logic Off Topic list

I want to have an authentic tape delay effect. I want to automate the 
feedback and maybe other parameters to make dub reggae in a 70's style 
and fashion.
I am confident in UAD-1 effects and will probably just buy it anyway.
I don't think the Logic tape delay is as good as a tape delay plug in 
could sound. Plus you can't do that effect where you change the tape 
speed. Can the UAD-1 RE-201 do that?
