Hah I just got a painful reminder of why we need this feature when I went through Presonus's blog's wonderful "Friday Tip of the Week: Through Zero Flanging" The author recommends setting the Delay Time curve in Analog Delay to "from 1 ms to 13 ms" for his patch. Can somebody tell me how you're supposed to pinpoint that range on this graph, without numeric entry? I had to try moving the dot around by 1 pixel 3 or 4 times.
