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? Roman.
