I would use the dual delay, set the note value and then use Tap Tempo. This would allow you to use the same setup on different tracks
Hi Kellerblues, thank you for this option, but unfortunately no luck. Both delay settings behave as a normal standard delay setting.
It turns out to be very difficult, if not impossible to create such a delay for a Kemper.
I also have found out that you can get a free (!) patch for this exactly sounding 1/8 dotted delay if you are an owner of the Boss Katana amp. Lucky players...!
