I was stating that a Shimmer effect will be part of a new upcoming firmware (5.0 I assume) along with all the other new delays. It was demonstrated in videos I have saw from Namm and was also available briefly by accident via a couple of rigs that appeared on rig exchange.
Was just letting the OP know that this feature will be coming to our Kemper.
The effect that you are referring to as "shimmer" is probably the crystal delay that was shown at NAMM.
