when in life delay is same and linked, it sound lots diffrent after parameter change and restore old value and new start.

please look at video, it is hard to explain. it happen only when delay is linked and same for left and right. When change during playback the values of rates for pitch and change back to old that it sound lots diffrent.
when click on stop and then on play again it sound same as before, but is very silent. i use 100% wet to hear better. in reaper 64 bit version 5.x diffrent versions test
