As per Liam's quotes :
" Lexicon PCM70 Circular Delays Preset - Steve Lukather's main delay setting instead of using reverb.
As close as I can get, Lexicon preset has 42% Diffusion (smear) on the repeats, this option isn't available in the Kemper Rhythm Delay, at least not yet.
To get close to the diffusion/smear you may want to place a room reverb or reverb of your choice after the delay and set the Del/Rev mix to only effect the delay tails and not the dry guitar then dial the amount of reverb to taste, usually around 20% to 40%. This is a work around but doesn't sound as nice and spacey as the smear parameter on some of the other delays. Here's hoping its eventually included on all the delays. You could also try some high cut that may make the delay tails disperse in a similar manner to try and simulate smear.
I understand why the Rhythm Delay works on a ratio or note division format, but for this preset would have been much easier if I could have just dialed in 888ms, 584ms and 292ms, but the percentage settings are spot on to these times. Due to the way the feedback function works in the Quad Delay won't be able to recreate this effect, the Rhythm Delay however seems to be the only way to pull this off.
Make sure the TO TEMPO is off.
This should make the delay run around you head in a "circular" manner, initial note comes center from the guitar, then the taps pan left, then to right, then to the center and back around again.
